1. Publishable summary SACRA (Spectrum and Energy efficiency through multi-band Cognitive Radio) addresses the implementation of a multi-band cognitive radio technology for spectral and energy-efficient broadband communications and targets, as major outcome, a proof-of-concept.

Project context and objectives

Energy efficiency and flexibility in the use of radio spectrum are two major research challenges for the development of future wireless communications technologies. To address these challenges, SACRA project designed and implemented a multi-band cognitive radio technology for future broadband communication devices.

SACRA developed a cognitive radio technology that is able to perform an optimal joint resource allocation on two separate frequency bands of the radio spectrum. The objective is to distribute the user data flows in an optimal way, based on measurements of radio spectrum occupancy and other inputs of interest. To support such cognitive operation, an advanced hardware platform is needed: SACRA addressed jointly these different aspects in one project to guarantee a coherent system approach towards a target scenario of interest defined at the beginning of the study. The innovation and impact brought by SACRA project are therefore in the combination of innovative approaches on radio frequency front-end and base band components design with new cognitive radio algorithms integrated into a single demonstrator platform.

The main SACRA objective is to develop this demonstrator in order to validate the complementary enabling techniques designed for cognitive systems to increase the overall system gain (throughput/power compromise), especially for IMT-advanced target. The demonstration is a major technical achievement as well as a valuable tool to promote the SACRA approach; it will be proposed to address the next challenges in the wireless communications domain.

Performed work and main results

In SACRA project, the technical approach consists first in the definition of a target scenario for the study, in the specification of global system requirements (architecture, target figures, characteristics) and in the definition of working assumptions and parameters. Based on this common framework, the different enabling techniques are studied and beyond- state-of-the-art solutions are proposed.

The regulation in several European countries is currently attributing the 800 MHz (790-862 MHz) band, also called Digital Dividend, to radio mobile communications (LTE and following) and considers a joint license to operators with the 2.6 GHz (2.5-2.69 GHz) band. The initial intent is to have a full coverage using the lower band for large coverage, typically for rural areas, while 2.6 GHz band would be used in high density areas. Such a static use of the two bands may appear inefficient in some conditions, depending on the traffic load, the propagation environment and the terminal positions. SACRA proposes two additional features to allow a more dynamic behaviour of the operating network:

• the capability to use jointly and simultaneously two bands taking into account instantaneous conditions, especially the environment, the system state or the communication needs;

• the capability to perform secondary use of the spectrum in the TV white spaces.

The target scenario is presented in the figure below:

Based on this general framework, three use cases have been identified for their interest considering the current standardization context (in particular LTE-Advanced), the technical challenges to be addressed and their economic potential. These use cases are:

• intra-cell and inter-cell spectrum aggregation; • cognitive relaying; • broadband access around home.

Intra-cell carrier aggregation consists in improving the capacity and/or coverage of an infrastructure deployed in a licensed band using additional resources in the TVWS. In the inter-cell case, the concept of carrier aggregation is extended to the case of two cells, either co-located or distant, in order to serve one single user equipment. Besides, thanks to an advanced use of the available bands, including the TVWS, cognitive relaying will improve the cell edge throughput or better cover shadowing areas, whereas cognitive femtocells will provide a better coverage, compared to the current status of LTE-Advanced.

An analysis of the spectrum aggregation and cognitive relaying business cases was conducted, based on techno-economical motivations to select these business cases, on the economical opportunities they will open and on an evaluation of the benefits they would provide. The business architecture models that have been proposed for these business cases have been integrated and extended to build, from the identified ecosystem model, the SACRA business architecture reference model that shows the business roles, their interrelations and the corresponding revenue flows.

The requirements to design the enabling techniques that are investigated in SACRA have been specified from the use cases. These requirements and the functional blocks that have been identified and defined have led to the elaboration of the reference model and reference architecture.

The study of the enabling techniques to design a SACRA system was completed, based on the specification of the use cases and requirements.

Several spectrum sensing methods have been compared using common simulation platform in order to identify the most interesting techniques and to select the algorithms for the SACRA demonstration. Updates of the classification method without quiet period using the exclusion of unreliable nodes have been done. Another classification method based on higher order cumulants for non-OFDM signal has also been studied. Various MIMO transmission and reception strategies or algorithms have been proposed for cognitive radio systems.

The CRRM algorithms developed over the previous years have been validated through simulations and compared against the state of the art approaches. The system control loops and the relationships among the Radio Resource Management algorithms of WP3 have been thoroughly analyzed and the traffic overhead induced to the system has been identified. This work led to provision of detailed scenarios based on the SACRA use cases and the extraction of the System Architecture based on the LTE-A. The framework for sensing configuration (algorithm selection and parameter setting) specified and the sensing configuration process defined over the previous periods has been

6

validated through simulations. The coordination and cooperation with sensing and classification has been provided and the software module for sensing control has been integrated to the SACRA platform.

The specification of the RF modem and building blocks has been completed. In order to highly reduce design and integration risk, the hardware structure, partitioning and platform of the SACRA modem has been improved. The detailed interface definition is completed, and performance results for the building blocks are published. Two different solutions, respectively for mobile phones and laptops, have been investigated to design a multiband antenna with dual polarization, and prototypes, with good performance results, are available. A tuneable band pass filter has been designed and optimized for the TVWS band. The development and layout of the ADC circuit has been finalized and sent to the foundry. The design of enhanced antenna switch PCB, an analog RF FE extension board for enhanced MIMO, has been finalized.

In the third period the EMBB baseband digital processor has been complemented with a Software Design Kit comprising: - an open source software reference library (libembb) used for algorithmic evaluations, - an open source real time operating system (MutekH) ported on EMBB, - a set of software drivers of the different DSP units, for MutekH, ported on EMBB, - a convenience software library built on top of MutekH and its software drivers, ported on EMBB, - a SystemC virtual prototype for system level simulations, - a UML profile (DiplodocusDF) and a UML design entry tool (TTool) used for applications high level modelling and capable of generating the equivalent embedded software for EMBB. Besides, a deep investigation and evaluation of the association of Digital Pre-Distortion, PAPR reduction and RF impairments compensation has been conducted for the SACRA terminal. A measurement campaign was also organized.

In order to demonstrate the multi-band cognitive radio concept developed in the project, a scenario that drives the implementation and demonstration activities has been defined and specified, based on the definition of the spectrum aggregation use case. The specifications for the system integration including software and hardware integration, as well as the step-by-step integration procedure to enable the validation of efficient cognitive radio communications have been defined and followed to realise the final demonstrator. Thank s to an agreement with French regulator, for the demonstration it will be possible to transmit/receive over the air in real time.

Final results

The innovation and impact brought by SACRA project are in the combination of innovative approaches on Radio Frequency front-end and base band components design with new cognitive radio algorithms integrated into a demonstrator platform. The major outcome of SACRA project is a proof-of-concept able to communicate jointly and cognitively in two separate frequency bands, which corresponds to concrete needs today in Europe. More precisely, the project has provided:

7

• application scenarios for multi-band cognitive and energy efficient systems aware of their environment and interacting with it to optimize their performance while minimizing interference to other systems,

• broad- and multi-band energy efficient RF architectures including antennas, RF front-end components and terminal architectures,

• integrated opportunistic networks and infrastructures aiming at a global optimisation of resources,

• innovative enabling techniques such as distributed and collaborative sensing, spatial and polarization based diversity, to efficiently exploit the capabilities given by the flexible architectures mentioned above,

• a real-time demonstrator integrating the RF front end components, digital base band processing, embedded software and algorithms on a flexible radio platform to demonstrate the target application scenarios.

In the final demonstrations, a dual band communication is performed, as initially planned in the project. The demonstration setup includes:

• the SACRA terminal (including antennas, RF front End, Motherboard) • a EnodeB equipment with dual band capabilities

The demonstration illustrates a real-time communication through 2 bands, 2.6 GHz and TVWS. The communication is LTE-based, and implements carrier aggregation mechanisms. Moreover, cognitive radio algotihms such as sensing and signal classification are also validated on the SACRA hardware architecture. TVWS is used as a sensing and classification band.

Expected impact

The cognitive radio concept is expected to become the most important technique able to improve the efficiency of the radio spectrum use and a key enabler to support the Future Internet. It will represent a crucial technology on the way to future high-capacity wireless communications networks, and thus major impacts are expected. Jointly with other European projects on cognitive radio related topics, SACRA will help to support a European leadership in the area of wireless technologies. SACRA will support energy efficiency and flexibility in the use of spectrum resources, which are major research challenges for future wireless communications, as highlighted by the European Commission Work Programme.

As SACRA is addressing both the study and the design of hardware components to support the cognitive radio approach, it will provide key technology close to a product for coming wireless devices. Considering the crucial need for wireless technology to cover the growing capacity demand, wide market opportunities can therefore be foreseen.

In order to make applicable the concept of cognitive radio, the findings of SACRA will provide inputs to standardization groups. SACRA outcomes, and especially the demonstrator, will also be of interest for regulation bodies, as they will help them to build new regulation policies according to what is technically feasible with future wireless technology based on cognitive radio concept.

2. Project objectives for the period

2.1. Overall project objectives for period 3 In the first period of the project, the target scenario and use cases for the project have been defined, and the requirements for the SACRA terminal and the demonstration have been specified. This initial step allowed to start the specification and the investigation of the enabling techniques (sensing, RRM, RF components, baseband digital processing) on a common basis. This investigation leaded, during the second period, to the design and asses of the identified techniques. Moreover the system integration was specified and the validation scenarios and methodology defined. In period 3, the overall objectives were to:

• Finalization of the design and assessment of the signal classification techniques, space-time polarization codes, MIMO transmission and reception algorithms, Cognitive Radio Resource Management and intersystem networking mechanisms;

• Finalization of the design of the RF building blocks (antennas, analog front-ends, mother-board, ADC and interfaces), on the development of the software design suite, and on the definition and assessment of RF/BB co-design techniques (combination of Peak to Average Power Ratio reduction and Digital Pre-distortion techniques);

• Finalization of the software design suite, including the UML-based design framework and the software generation from high level UML models;

• Integration of the SACRA platform building blocks; • Validation trails • Completion of a recommended system definition; • To disseminate SACRA outcomes (conferences, journals, workshops, concertation

meetings, standardization bodies) and to organise a SACRA workshop.

2.2. Recommendations from period 2 review In addition to the initial objectives listed above, the consortium built an action plan to take into account the recommendations from the period 2 review. This section reminds the recommendations and the consequent actions that have been defined in the “Response to Technical Review of Period 2” document and presents the results that have been achieved.

Recommendation: D2.2 needs to be revised to complete section 5.3 (concerning complexity) Action: Section 5.3 of D2.2 has been revised in the version 2.0 of D2.2. Status: The version 2.0 of D2.2 has been delivered on 13 April 2012. Recommendation: D6.2 needs to be revised to give a detailed timetable for completion of the stages to be passed in completing the demonstrator. Action: The planning of the integration stages which was presented in section 6 of D6.2 v1.0 has been refined and is reported in section 7 of D6.2 v2.0. Recommendation: A test matrix is to be submitted explaining the nature of verification of the key project objectives. Action: The matrix presenting the nature of the demonstration activities is reported in the version v2.0 of D6.2. Recommendation: The functionality of the trial and demonstration is also a concern. Techniques described in WP2 and WP3 results must be properly followed up in WP4, WP5 and the demonstrations/trials envisaged in WP6. The implementation is clearly an enormous effort and

9

should be given a high priority to focussing all efforts on the demonstration making its planning more detailed and broadening its scope if possible, e.g. number of channels within the limitations of the hardware capabilities. Action: In the version v2.0 of D6.2 further details are given on the demonstration activities of the techniques developed in WP2 and WP3 (sections 5 and 7). Status: The version v2.0 of D6.2 has been delivered on 13 April 2012 including all the aforementioned modification. Recommendation: Peer review of deliverables between workpackages is encouraged to foster cooperation. Status: The peer review of the deliverables (implemented since period 1) was pursued during the last year with a focus on XWP reviews. Names of reviewers were added in the deliverables. Recommendation: An extension of active contribution to standardisation with measurable impact, e.g. on ETSI RSS, is recommended. Further standardization bodies could be addressed. Status: SACRA partner contributed to the definition of use cases and functional requirements for carrier aggregation in TVWS which fall into open WIs in ETSI RRS technical committee (TS102.907 and TS 102 946). As a next step, after having progressed with the work on use cases and requirements definition, ETSI RRS plans to create new work items on the definition of the architecture and protocols for Cognitive radio systems operating in TVWS band and associated Cognitive Management and Control mechanism definition. During the lifetime of the project, ETSI RRS technical committee was not yet ready for creation of this new WIs because TVWS requirements were not yet mature. So, SACRA partner was not in a position to contribute further in ETSI RRS. For the time being (March 2013), ETSI RRS is currently discussing the way forward and the approval of new work items (March meeting in Maisons-Alfort). One of them will deal with the definition of the system architecture for the use of spectrum by White Space Devices (WSDs), Recommendation: The APPR (D8.2.2) is rejected because the tables that explain resource usage are insufficiently detailed, especially for equipment. Status: These tables have been updated in the version 1.14 of D8.2.2 which has been delivered on 13 March 2012. Action: Misleading sentences in the APRR have been identified and the APRR has been revised during the 8th F2F meeting (in Erlangen). Status: The version 1.15 of D8.2.2 has been delivered on 29 March 2012 with the identified corrections. Action: For the trials Monaco Telecom or Eurecom in Sophia Antipolis have been identified. However, the availability of spectrum for the final demo is not yet granted. Status: A request for spectrum in Sophia Antipolis for the day of the final review was sent, The French regulator gave an agreement to use for transmission in FDD and TDD the following bands:

• 811-821 MHz and 852-862 MHz

• 2530-2550 MHz and 2650-2670 MHz

Action: Section 7 of D3.2 will be enriched with 1 section per partner (i.e. NKUA, IT, NTUK) that shows how learning and reasoning is addressed by the WP3 algorithms. NKUA and IT have already provided draft enrichments; NTUK will provide inputs in the following weeks according to WP3 refined workplan. Action: Although only a subset of WP3 algorithms will be demonstrated due to the limitations of the hardware capabilities, Section 7 of D3.2 will be enriched with one (1) section per partner that

10

shows how learning and reasoning is addressed through the WP3 algorithms and Section 6 will include the information exchange scheme of the algorithms and the information model for policies. Status: Deliverable D3.2 was delivered with the expected sections. Action: The proposed solution for carrier aggregation (i.e. Genetic Algorithm) will be compared to other alternative approaches (e.g. score-based). Additional simulation results will show the benefits from the Genetic Algorithm approach and will be included in D3.2. Status: Deliverable D3.2 included additional comparisons and simulation results for Genetic Algorithm approach. Action: Genetic Algorithms are used as function optimization techniques for NP-hard problems. In this context:

• GAs utilization in WP3 case is complementary to the generic solutions described in the context of D3.1, as a genetic algorithm is used at the highest levels of the CRRM hierarchy in order to partition traffic flows into sub-bands and carrier components.

• The partitioning (genetic) algorithms are supported by the sensing configuration block as they use the primary user sensing information to address the LTE resource block allocation across the bands. They are also supported by the Distributed CRRM block of the CRRM system, as they use information stemming from opportunistic users, as regards their access to the unlicensed band.

• As mentioned afore, the use of GA is closely related to the other CRRM blocks as it receives inputs from them so as to proceed in decision making (i.e. partition traffic flows).

The additional information on the genetic algorithms will be reported in the next reports of WP3: in the second issue of D3.2 v2.0 but also in M3.3 and D3.3 Status: Deliverables D3.2 and D3.3 included the additional required information. Action: Milestone M3.2 describes the general principles for policy based management, followed by the description of concrete algorithms and their relationships to the rules and policies used to design the SACRA CRRM. This work will be used as a basis for the description of information model for policies in section 6 of D3.2. Furthermore, section 6 will be enriched in order to provide the information exchange scheme of the algorithms. Status: Deliverables D3.2 was delivered with the required information. Action: D3.2 will be revised in order to justify why MCAS is used in this WP and not described in D2.2 and provide the differences with the cyclostationary detector. Status: Deliverables D3.2 was delivered including expected justification on MCAS use. Action: Section 8 of the deliverable D3.2 shows the relation of each of the CRRM components with the SACRA indicators. CRRM system is the combination of all these blocks. Furthermore, the assessment of the CRRM in terms of the SACRA indicators is out of the scope of this deliverable and will be provided in the D3.3. Status: Deliverables D3.3 was delivered and provided the assessment of the CRRM in terms of the Sacra indicators. Action: To improve the monitoring of the use of the resources, an updated person months table completed by a planning for period 3 will be provided by IT, NTUK, IIS, EURE and DMCE, and will be included in the QMRs for period 3. The overspending in terms of PMs will not impact their contributions planned in period 3.

11

Status: The planning for the aforementioned partners was included in the QMRs and deviations were followed Action: The cross WP discussions, through the organisation of cross WP meetings, WPL conference calls and cross WP reviews of deliverables will be pursued. Status: Several meetings and conference calls were organized and the deliverables were internally reviewed by cross WP reviewers.

3.1. WP1: Target scenario and system definition Leader: TCS

Participants: NTUK, VTT, IT, EURE, DICE/DMCE, UoA, INF/IMC

Start month: M1 – End month: M34

This work package addresses the overall system aspects. In the previous periods, the target scenario, use cases of interest and overall requirements have been identified and refined, in an iterative way, using the results from the technical studies. This study led, with the specification of detailed requirements for use in the technical WPs of SACRA, to the refinement of the reference architecture. In parallel, the SACRA ecosystem and business cases have been defined and studied, and a business architecture reference model has been proposed. In the 3rd period, the main objective of this work package was to provide a recommended system definition. Progress: The objective of WP1 efforts in this last period was to deliver a complete and stand-alone deliverable which summarizes the global achievements of SACRA project; to achieve it, a strict collaboration between WP1 and the other technical WPs (WP2 to WP5) was realized in order to collect the different technical results of the project. During the first part of the year, WP1 basically monitored the results in the other technical WPs of SACRA in order to have inputs to elaborate the recommended final system definition. According to these inputs the elaboration of the SACRA system recommended started and progressed in an iterative way, updating the system according to the feedbacks from other WPs. The description of the terminal architecture, of its modules and of its interfaces, retrieved from previous deliverables of the WP, was also revised during this process of definition of a recommended system. All these efforts leaded, at the end of the WP, to present a recommended system design supports sensing and classification for protection of the primary users, and is able to manage an opportunistic access to the TV white spaces on top of the operation in the licensed bands. This final recommended system definition was detailed in the deliverable D1.3. This document, in addition to the presentation of the SACRA recommended system definition, compiles the technical and economic achievements of the project, and provides the outcomes and recommendations that are valuable for the future deployment of cognitive radio systems. It is a stand-alone document that basically summarizes the global achievements of SACRA project and that gives a clear view of the final project outcomes. Significant results: The main achievement of this year from WP1 is the definition of the SACRA recommended system through the strict collaboration between WP1 and other WPs. The deliverable D1.3 (delivered on 9th of November 2012) was the final outcome of the WP and allowed to have a final synthesis of the project achievements. Use of resources: More resources (in terms of PMs) than initially planned were dedicated to WP1. This is mainly justify by the intention to realise a final deliverable which includes all the results of the project and that can be used as reference for future studies on the topics considered in SACRA project.

3.2. WP2: Sensing and access techniques for cogniti ve spectral and energy efficient radio

Leader: VTT

Participants: NTUK, IT, EURE, INF/IMC

Start month: M3 – End month: M27 This WP develops sensing and access techniques algorithms for cognitive radio. In spectrum sensing, the goal is to study algorithms in single and/or cooperative terminals. In addition, for signal classification and separation, the goal is to consider algorithms for multiple secondary systems. Moreover, in MIMO algorithms including polarisation dimension is studied. Outcomes of this WP will be used in WP5 and WP6 for implementation of the algorithms and demonstration purposes, respectively. Progress: In task 2.1, studies on wide-band spectrum sensing techniques for multiple-antenna cognitive radio networks have been carried out. In addition, a joint sensing and primary user localisation algorithm in cognitive radio networks by casting both of the addressed topics as a compressive sampling problem has been contributed. The complexity evaluation of the sensing algorithms using the embedded library as well as performance evaluation using common framework under FCC requirements have been performed. Updates of some previously reported sensing algorithms have also been given. As a joint WP2/3 contribution, a sensing control, optimisation of cooperative sensing, and novel SNR prediction method have been considered in collaboration with WP3. The final results on spectrum sensing have been reported in D2.5. In task 2.2, updates of the classification method without quiet period using the exclusion of unreliable nodes have been done. Another classification method based on higher order cumulants for non-OFDM signals has been studied. Some updates of the classification studies have been reported in D2.5. In task 2.3, we have made proposals for multi-antenna (spatial) cognitive radio paradigms (overlay, underlay, interweave) and for how overlay multi-cell communications could be handled in various degrees of cooperation. We have proposed a transmission strategy where interference alignment carried out at interfering base stations is exploited with a low complexity receiver structure. The performance investigations of interference-limited cell-edge users in cellular networks have been done. We have considered the characterisation of rate region in terms of rate gap evaluation from the capacity region for overlay cognitive radio systems where cognitive nodes causally obtain the primary information instead of making genie-added assumption. We have been also working: 1) MISO interference channel: SINR balancing and beamforming design, 2) MIMO interference channel: distributed channel state information acquisition and filter design for weighted sum rate maximisation, and 3) underlay cognitive MISO interference channel: beamforming for weighted sum rate maximisation and spatial interweave for a MIMO secondary interference channel with multiple primary users. On the other hand, we have specified the generalised degrees of freedom for causal cognitive radio interference channel and extended the generalised degrees of freedom results to cognitive relays. In addition, power allocation for cognitive radio networks using the relative rate utility framework has been considered. Moreover, the space time coding algorithm has been developed and resource allocation under polarised multi-carrier multi-user systems including precoding as well as power allocation and bit loading have been further considered. The power optimisation for a MIMO OFDM system with polarisation diversity capability has been

15

investigated. The MIMO algorithm studies have been reported in D2.4 as well as the second version of D2.4, i.e. D2.4v2.0. Significant results: All WP2 milestones have been achieved. Two deliverables (D2.4 and D2.5) have been delivered during the period. In D2.4, various MIMO transmission and reception strategies or algorithms have been proposed for cognitive radio systems. The second version of D2.4, i.e. D2.4v2.0 has also been created where extended MIMO algorithm studies have been reported. In D2.5, the spectrum sensing considerations have been finalised. In addition, some updates on the classification studies have been reported in D2.5. Related to scientific results, several conference and journal papers have been published, accepted for publication, or submitted for publication during the period. Some of them are highlighted as co-publications with SACRA partners. Use of resources: The partners involved in WP2 did not report any major deviation between the actual and planned person-months.

WP3 main objective for the third period has been to finalize the design of the algorithms that constitute the Radio Resource Management system and the rules and policies that drive those mechanisms. The performance of each component of the proposed RRM system has been evaluated against state of the art approaches. Based on all the SACRA use cases identified in WP1 (i.e. Inter-cell and intra-cell Spectrum Aggregation, Cognitive Relays and Broadband Access Around Home), concrete scenarios and network system architecture where all the algorithms collaborate in the RRM system has been analyzed. Furthermore, all the algorithms developed in WP3 have been mapped to the SACRA functional architecture. Outcomes of this WP have been used in WP5 and WP6 for implementation of the algorithms and demonstration purposes, respectively.

This is in line with WP3 tasks that cover each a specific level in the loop hierarchy or the Cognitive Radio Resource management hierarchy, namely:

• Coordinated Radio Resource Management, • Multi-agent based autonomous system for opportunistic networks, • Integration of opportunistic wireless networks and infrastructure networks, • Behavioural Models for driving the systems with rules, policies and objectives.

Progress:

In the third period, WP3 activities have been related to the assessment of the SACRA CRRM mechanisms, to the mapping of those mechanisms to SACRA scenarios and to the provision of software modules for WP6 demo activities. The plan was set accordingly with milestones (M3.3 and M3.4) that provided inputs for the composition of the corresponding deliverables. M3.3 incorporated preliminary results of the RRM components regarding their performance, the sensitivity to assumptions, the stability and their behaviour when policies and learning techniques are applied, while M3.4 provided the missing link between WP3 and WP6. Specifically, M3.4 provided the description of the software modules that have been integrated to SACRA platform (sensing control mechanism), or are planned for simulation-based demonstrations (i.e., User and Flow partitioning algorithm, Cooperative Power Control algorithm) in WP6 context. Deliverable D3.3, as planned for the third period provided the final assessment of the RRM system, which comprises performance and stability evaluation of each CRRM mechanism independently and set the basis for the joint assessment of the Secondary Access Control mechanism and the Cooperative Power Control mechanism presented in D3.4. Furthermore, learning enhancements (when applicable) have been evaluated as well as the policy enforcement for the identified policies of the CRRM mechanisms. Deliverable D3.4, as planned for the third period, provided the mapping of the RRM system to the SACRA functional architecture and a detailed description of the invocation of the CRRM components in scenarios that are based on the identified use cases of WP1. Thus, this document is considered as the linking part between WP3 and WP1.

The delivery of D3.2 v2.0 with background traffic assessment of the RRM system, provision of information models and thorough description of learning enhancements upon the RRM components and delays of previous WP3 documents (i.e. milestone M3.2 and deliverable D3.2) are the fundamental reasons for delays of subsequent documents of WP3. More specifically, in order to

17

provide a detailed and thorough performance analysis of the CRRM system components milestone M3.3 and deliverable D3.3 have been delayed 2½ months each. This situation consequently led to 2½ month delay for the final reporting document of WP3 (i.e., deliverable D3.4), while milestone M3.4 delivered with 1 month delay.

Task 3.1 has ended. During the third period, Task 3.1 has been experimenting with the algorithms developed in the previous periods. All the CRRM algorithms have been thoroughly evaluated through various simulations. The experimental results have been reported in D3.3. Furthermore, joint assessment of the Cooperative Power Control and the Spectrum Access Control mechanisms has been performed in the third period and has been reported in D3.4.

Task 3.2 has ended. During the third year of SACRA project Task 3.2 focused on the required interactions of the sensing control and configuration with the sensing algorithms. The coordination and cooperation with sensing and classification has been provided. The implementation status (M3.4) of the sensing control mechanism has been reported in WP3 deliverables (i.e., D3.3, D3.4).

Task 3.3 has ended. In this task, the main objective for the third period has been to identify links and interactions for the RRM mechanisms’ communication and cooperation. This has been performed by identifying detailed scenarios based on SACRA use cases developed within WP1. In these scenarios, the interactions among the RRM components have been defined, so as to highlight the potential cooperation among them. Such procedure has enabled the extraction of the System Architecture, based on the LTE-A. Furthermore, in the mapping of the developed mechanisms to the SACRA functional architecture, the links among the proposed solutions have also been identified. This analysis has been reported in D3.4.

Regarding the communication overhead of the RRM mechanisms, the proposed solutions have been evaluated and the traffic overhead has been quantified; such quantification has been reported in D3.3.

Task 3.4 has ended. In this task, one of the main objectives of the third period has been to investigate the system control loops and the relationships among the Radio Resource Management algorithms of WP3. Furthermore, the assessment of the RRM mechanisms, once rules and policies have been injected in the system, has been performed; the outcomes have been reported in D3.3. In terms of this task, when applicable, the mechanisms have been enhanced with learning capabilities and the corresponding results that show improved situation awareness have also been reported in D3.2 version 2 and D3.3.

Significant results:

All the tasks have been completed and all the objectives of WP3 have been achieved. All the deliverables of the period have been delivered and the milestones of the period have been achieved with minor delays. Such delays are partially justified due to delays of the previous periods of the project.

During the last year of the project all the CRRM algorithms developed during the previous years have been validated through simulations and have been compared against the identified state of the art approaches. Task 3.1 has fed deliverables D3.3 and D3.4 as well as milestone M3.3.

During the last year of the project the coordination and cooperation of the sensing configuration module with sensing and classification has been provided and has set the basis for the integration to the SACRA platform. Task 3.2 has fed deliverables D3.3 and D3.4 as well as milestone M3.4 and has achieved all its objectives.

18

Task 3.3 during the last year of the project has provided a thorough study on the interactions among the RRM components identifying thus the potential cooperation among them as well as the traffic overhead induced to the system. This task has fed deliverables D3.3 and D3.4 and has achieved all its objectives.

Task 3.4 has focused on the assessment of the RRM mechanisms once specific rules have been set and policies have been injected to the system. These studies have been validated through simulations allowing thus to identify the most interesting approaches that improve the flexibility of the SACRA system to policy enforcement cases. This task has fed deliverables D3.2 version 2 and D3.3 and fulfilled all its objectives.

Use of resources: The partners involved in WP3 did not report any major deviation between the actual and planned person-months.

3.4. WP4: Antenna and Radio Frequency Modem Leader: DICE/DMCE

Participants: TCS, IT, IIS, EURE

Start month: M4 – End month: M33 The main WP4 objectives of the final project period were to finalize and to validate all specified key building blocks of the modem and to integrate modem functionality for the final 4x4 MIMO demonstrator platform. The developed, integrated hardware enables demonstration of software and hardware algorithms of WP2, WP3 and WP5. The following deliverables have been delivered during the third project period.

• D4.3: Final report on antenna design, transmitter, and receiver RF part, and ADC architecture and design

In task 4.1, the antenna design for mobile phone applications has been validated and measured integrated into the modem hardware of the demonstrator. The antenna for laptops has also been finalized. Additional studies on diversity performances have been performed in order to take into account the rotation of the terminal by the user during the communication link. All results of the antenna have been published within D4.3 and D4.4. In task 4.2, a new ADC design has been finalized fixing a hardware bug and was sent to the foundry. In task 4.3, the analog front end has been finalized and validated. Results on AFE and enhanced antenna switch PCB have been published in D4.3 and D4.4.

3.5. WP5: Flexible baseband design: application mod elling, embedded software generation and validation

Leader: IT

Participants: TCS, NTUK, VTT, IIS, EURE, DICE/DMCE, UoA, INF/IMC

Start month: M3 – End month: M30 This work package addresses the issues related to the flexible baseband (BB), the interfaces with the radio frontend (RF) and the embedded software for the cognitive radio. In the context of the SACRA project the BB digital processing will be implemented on a complex, advanced BB processor embedding a large collection of micro-processors and dedicated hardware accelerators. Designing the embedded software of such platforms is extremely challenging. The main goal of WP5 is thus to provide a design framework to ease the modelling, validation and production of the embedded software. It is also in charge of the interfaces with the RF and RF-BB co-design (partitioning of processing between RF and BB). Its outcomes will be used in the WP6 activities.

Progress: Tasks T5.1 (system requirements and embedded software modelling), T5.2 (validation techniques) and T5.3 (embedded software library) ended during the previous period. Task 5.4 (Software generation) ended at M30. The DiplodocusDF formal, domain-specific, UML profile has been finalized. The framework now supports code generation from the UML model into C-language. These developments have been tested with the modelling and the semi-automatic software generation of example applications (Energy detector and Welch periodogram detector). The software generators have been integrated in the TTool UML framework. Milestone M5.5 (Complete software design suite available and ready for integration in WP6) has been delivered. The D5.3 deliverable (Adapted BB processor, embedded software generators, integration in the TTool design framework) has been delivered with examples and user documentations. The delivery of D5.3 was the final task of this work-package. In task 5.5 (RF/BB co-design and interface), the work continued with enhancements of the DPD and PAPR algorithms. The task continued with actual measurements campaigns on hardware power amplifiers. The WP progressed as expected. There have been no significant deviations from the initial plans. D5.3 delivery has been delayed by one month and a half (mid-August instead of end of June) in order to provide better examples and documentations but this had no impact on other activities.

Significant results: Integration of the DiplodocusDF formal UML profile and its companion software generators to the TTool framework. Modelling and software generation of sensing algorithms. All tasks have been completed. The D5.3 deliverable and the M5.5 milestone have been delivered.

3.6. WP6: Integration, validation and trials Leader: EURE

Participants: NTUK, VTT, IT, IIS, DICE/DMCE, UoA, I NF/IMC

Start month: M6 – End month: M36 WP6 is dedicated to the definition of the planned integration and test activities, and to the specifications of the needed tools and resources to realize them. A selected set of scenarios, among those studied within SACRA project, will be chosen to demonstrate the multi-band cognitive radio concept developed in the project.

Progress: The technical approach of WP6 is to (step 1) use the inputs of WP1 in term of scenarios and use cases. From those scenarios, we derive (step 2) a set of general specifications for the various HW and SW blocks (blocks that are developed in the WP2 to 5). From the general specifications, a set of detailed specifications and interfaces are defined for implementation. The various blocks are developed in the WPs, according to their specifications, and finally integrated and demonstrated (step 3) in WP6. WP6, as WP1, also interacts with the others WPs in order to ensure the global coherency of the project in term of demonstration (interfaces between various blocks). On the final WP6 demonstration, we have implemented an intra-cell spectrum aggregation, with a cognitive access of TVWS band and a classical cellular connectivity in 2.6 GHz. The data flows from the 2 bands will be aggregated in the PHY/MAC layers. During the third period, the WP6 activities have focused on:

1. The finalization of the WP2/WP3 algorithms implementation 2. the integration of Software parts 3. the integration of Hardware parts

1- Concerning the WP2/WP3 algorithms, at least 2 algorithms of sensing and 1 algorithm of classification have been integrated. The description of the algorithms and their implementation on the baseband processor is given in the deliverable D6.3. 2- The integration of Software parts. The work has been conducted thanks to the step by step integration procedure (described in D6.2). This procedure assumes that the WP4 modem functional (this task has been done successfully) and that the WP2/3 algorithms are integrated in the WP5 library. Iintegration activities have been conducted both on the terminal and the ENodeB side. On the terminal side the SACRA modem including the antennas, the RF FE parts and the motherboard have been integrated with the software part. We are able to transmit and receive a signal (sinusoid, LTE, …) generated in matlab. We are able to control the RF remotely from the host PC. Moreover, the Spectrum Aggregation software have been developed and is currently under debug (date 18/12/12). On the EnodeB side, several activities have been conducted:

- the Integration of WP2/WP3 algorithms on the baseband library

- integration of the base band part with the protocol stack

3- The integration of Hardware parts

23

Integration activities have been conducted both on the terminal and the ENodeB side. On the terminal side the WP4 modem has been integrated with the host PC trough the PCI-E interface. This interface allows the samples transfer (Data) and the modem control including RF. On the ENodeB side, 2 high power RF front end have been developed, one in the TVWS band, and the other at 2.6 GHz. Those high power front end have been integrated with the transceivers and the base band processing board.

Significant results:

The significant results of the period are:

- The integration of ENodeB parts, including WP2/3 algorithms thanks to the WP5 library, protocol stack and RF parts including Power Amplifiers, filters, Low Noise Amplifier.

- The design of the software multi-threaded application that runs on the baseband processor and controls all activities (sensing, classification, data transfers between the soft modem PC and the light RRM PC)

- The integration of the SACRA UE (terminal), including WP4 modem, RF control, and the protocol stack

- Implementation of the the Spectrum Aggregation software

Use of resources: The partners involved in WP6 did not report any major deviation between the actual and planned person-months. In this WP the main resources will be used in the last period of the project.

• T.7.2.3: Courses for students

As targeted, SACRA results and know-how is included as part of future graduate and postgraduate courses. In June 2011, an engineer – system architect from IMC (formerly Infineon Technologies France) came to give two lectures on System in Package and System on Chip architecture for an UMTS WCDMA receiver at Telecom ParisTech / Institut Telecom.

32

Another two lectures on RF transceiver architecture, design and challenges for cellular systems has been given by an former engineer – system architect from DMCE (formerly DICE). These lectures have been given to Ph.D students and Ms.C students from Telecom ParisTech / Institut Telecom. In June 2011, three professors from Telecom ParisTech / Institut Telecom gave a tutorial on cognitive and opportunistic radio at The 9th IEEE International NEWCAS Conference. University of Athens (UoA) has also been offering a couple of courses on cognitive radio issues both in theoretical basis and in implementation/simulation perspective. Furthermore, the postgraduate course “Advanced topics in wireless communication networks” has been offering a series of lectures in cognitive radio networks, since October 2010. Professor Nancy Alonistioti gives a series of introductory lectures in order to present cognitive radio issues. In addition, students are invited to search for topics and state of the art in order to make their own presentations. • T.7.2.4: Open source software

The target baseband processor of the SACRA project is the EMBB generic processor developed by IT and EURE. EMBB is the basic building block on top of which SACRA baseband applications have been developed. This processor comprises a Control System (CS) with a general purpose processor plus its peripherals and a configurable Processing System (PS). In the context of SACRA the CS is based on the open source Leon3 Sparc processor from Aeroflex Gaisler (http://www.gaisler.com/). Designing the software layers for this kind of platform is very challenging. WP5 thus also designed a software design framework for the specification, modelling, design and validation of the baseband software. This framework comprises a software library named libembb, a customization of a configurable tiny operating system named MutekH (http://www.mutekh.org/), software drivers, convenience software libraries, a SystemC virtual prototype based on the SoCLib (http://www.soclib.fr/) library and an UML-based design entry tool (http://ttool.telecom-paristech.fr/) with a dedicated UML profile and UML to C translators. All these components are already (or will be after a necessary cleanup phase) available under the terms of free software licences. Moreover, the full synthesizable hardware VHDL code of the PS will also be distributed as free software as soon as stable enough.

WP7.3: Exhibitions

SACRA members participated to Future Network & Mobile Summit (FuNeMS) 2011 conference in Warsaw (June 15th-17th, 2011) and to IEEE DCOSS 2011 in Barcelona (June 27th-29th, 2011) with a stand in which the objectives and the current results have been presented. The representatives also participated to RAS cluster meeting before FuNeMS conference. SACRA partners disseminated SACRA results on sensing and on RF front-end during the GDR workshop organized on May 9th and 10th 2011 at Télécom ParisTech. Besides the SACRA coordinator made a presentation at the FlexSUS workshop.

WP7.4: Standardization and Regulation

SACRA project was presented during the kick-off meeting of new project (DySPAN P1900.6a) aiming at defining “Procedures, Protocols and Data Archive Enhanced Interfaces between sensing nodes”. It has been noticed that X2 interface for supporting sensing info exchanges (as shown in SACRA ref model) has not been considered in 1900.6, and could be something to consider. As part of ETSI RRS, SACRA partner contributed to the definition of functional requirements for carrier aggregation in TVWS which fall into the Spectrum Management

33

Requirements section of TS 102 946. In addition, requirements for LTE operation in TVWS are presented for the Radio Access Requirements Section. SACRA partner tracked in depth the Feasibility Study on RF Performances for Cognitive Radio Systems Operating in UHF TV Band White Spaces (TR 103 067) in which several contributions have been discussed, such as combined sensing and geo-location techniques and coexistence issues. The second important technical specification is dealing with systems requirement for operation of CRS in TVWS (TS 102 946). As a next step, after having progressed with the work on use cases and requirements definition, ETSI RRS plans to create new work items on the definition of the architecture and protocols for Cognitive radio systems operating in TWS band and associated Cognitive Management and Control mechanism definition. It will bring new opportunities for SACRA partners to contribute based on WP1/2 and WP3 outcomes. This work is intending to be addressed within the Coordination and Support Action (Cognitive Radio Standardization Initiative- CRS-i) because at the time being, new WIS are not yet created in ETSI RRS framework.

More generally, one deliverable (D7.1) has been delivered on time at M36, providing an overview into the activities and plans for regulation, standardization, dissemination and exploitation that have already been achieved and are further expected to be accomplished throughout the remaining lifetime of the SACRA project. Significant results: Deliverable D7.1 was delivered presenting a snapshot on the status quo of the regulation, standardization, dissemination and exploitation efforts within the SACRA project for Year 3. Furthermore, the deliverable provides a detailed description the result achieved till the end of the project. Considerable outcomes have been achieved by SACRA, including both conference papers and journal publications (publication of 12 articles in Wireless Personal Communications journal, around 60 accepted papers to conferences). In terms of standardization, SACRA participated in working groups within the ETSI Reconfigurable Radio Systems (RRS). SACRA partner contributed to the essential normative specification allowing the definition of wireless systems operating in UHF TV WS band, meaning technical specification for systems requirement for operation of CRS in TVWS (TS 102 946). Additionally, significant courses and open source software have been offered allowing disseminating the SACRA results and know-how.

The SACRA consortium invested more efforts than initially planned in terms of PMs in order to achieve the expected objectives. This overconsumption of PMs has different reasons, but it is mainly explained by the involvement of more young researchers than originally planned by some partners and, for some partners, by the departure of some key contributors that had to be replaced. Despite the overconsumption in terms of PMs, the total costs respect the initially planned expenses. The data provided in the table are precise estimations based on the data that will be entered in the NEF system once the reporting session will be open. Some of these data are currently under audition; hence these data can still slightly change until the final submission into the NEF system (whose data are the only ones that can be considered as final ones).

4. Project management during the period This section details the management of the consortium activities in the framework of WP8. The objectives of this WP are to successfully manage the project development, to ensure that the consortium will reach its objectives and to co-ordinate activities with respect to European Commission. The management of the project is following the "Project Management Plan", detailed in the deliverable D8.1 that has been delivered on 1 March 2010. In period 3, TCS, as project coordinator, has handled the following management tasks:

• Monitoring the project results and ensuring the consistency with respect to the project objectives;

• Co-ordination of partners and project meetings; • Participation to the periodic review and definition of an action plan to answer the requests

and comments from the second review report; • Communication between the consortium and the EC.

4.1. Communication within the consortium

4.1.1. Communication means The SACRA mailing list and the BSCW server that have been set up in the first period have been used efficiently for internal communication and to exchange work documents. Emails were the main means to communicate between partners, but conference calls were often used for technical discussions in the WPs. Besides monthly WPL conference calls were organised for technical management of the project.

4.1.2. Consortium meetings In the third period, four consortium meetings have been organised, as detailed below. The 8th consortium meeting was hosted by IIS in Erlangen (Germany), on 29th and 30th of March 2012. The objectives of this meeting were to:

• Make the point on the management aspects and project schedule • Discuss about the feedbacks received after the second year technical review and organize

the corrective actions; • Discuss about the progress of the different technical WPs; • Discuss about the final demo current and expected status at the end of the project; • Organize measurements.

4.2. Status on the project planning The project achieved all its objectives and delivered all the expected deliverables, for some of them also an updated version was delivered in order to include the last results achieved during the project. Some delays were experienced for some deliveries, basically not exceeding one month (with few exceptions) in order to guarantee consistency and high quality level of the deliveries. In order to achieve all the objectives of the project and to complete the work of SACRA in line with the DoW, some partners invested more efforts in terms of person months than initially planned. This did not impact the total cost of the project, since mainly young researchers were involved in the project to complete the studies.

4.3. Dissemination In SACRA the WP7 is dedicated to dissemination activities. The actions led during the period have been reported in the last deliverable of work package 7 and summarized in section 7.1.

1 D8.2.1 v1.3 includes additional explanations in section 6 “Explanation of the use of the resources”. 2 This document D1.2 was postponed to M21 before being delivered on 12 October 2011, with no impact on the other activities of the project. 3 The delay in the delivery D3.2 is mainly due to the delay in the completion of the milestone M3.2. However it has no impact in the activities of the other WPs of the project. 4 A few broken links were part of the pdf version of D2.2 v1.0. These links have been restored in D2.2 v1.1. 5 As the possibility to make a patent application on pre-distortion algorithms proposed in D5.2 is currently investigated, this document is CO for the time being.
