Activity on CR in ITU-R 8A

1 What is the ITU definition of cognitive radio systems?

2 What are the closely related radio technologies (e.g. smart radio, reconfigurable radio, policy-defined adaptive radio and their associated control mechanisms) and their functionalities that may be a part of cognitive radio systems?

3 What key technical characteristics, requirements, performance and benefits are associated with the implementation of cognitive radio systems?

4 What are the potential applications of cognitive radio systems and their impact on spectrum management?

New ITU-R Question on "Cognitive radio systems in the mobile service"


Activity on CR in ITU-R 8A

5 What are the operational implications (including privacy and authentication) of cognitive radio systems?

6 What are the cognitive capabilities that could facilitate coexistence with existing systems in the mobile service and in other radiocommunication services, such as broadcast, mobile satellite or fixed?

7 What spectrum-sharing techniques can be used to implement cognitive radio systems to ensure coexistence with other users?

8 How do cognitive radio systems promote the efficient use of the radio spectrum?

IEEE P1900.4 in E2R standardization strategy


IEEE P1900.4 NRM block (ongoing work)

Security Issues

Functionalities for the Network Reconfiguration Management block:

Recovery of Context Information


IEEE P1900.4 TRM block (ongoing work)

Functionalities for the Terminal Reconfiguration Management block:

Representation definition of feed-back information

(from terminal to network)

Security

issues

P1900.4 is targeting specification of functionalities necessary for information conveyancebetween the network and the user-terminal

allowing distribution of decision making

with respect to the radio resource usage policies from the network.

NOTE


IEEE P1900.4 RERM block (ongoing work)

Functionalities for the Radio Enabler for Reconfiguration Management block:


At switch on:the terminal does not know the "current" configurations of the various networks, in particular the frequency bands associated to the Radio Access Technologies (RAT)

CPC purpose:To broadcast data allowing a terminal to acquire knowledge of the available RATs in the surroundings, without having to sense the spectrum.

Op.#1

???

One scenario for CPC

Possible solution:the terminal performs sensing of the spectrumProblem: this may consume a lot of time and power if many bands are to be sensed


At the airport, Operator #2: 2 preferred RATs,

at frequencies F2.1 and F2.2 respectively

Operator #3: 2 preferred RATs, with frequencies F3.1 and F3.2 respectively

The mobile is switched on.

Op.#2

UMTS: F2.1

GSM : F2.2

Op.#3

WiFi: F3.1UMTS: F3.2

RAT selection procedure at the airport in city BMobile is switched on it listens to the CPC. The mobile, taking into account its user profile for example, chooses the operator #3 and the WLAN technology.It starts its connection on the corresponding frequency indicated by the CPC.

Op.#2:- UMTS, F2.1- GSM, F2.2Op.#3:- WiFi, F3.1- UMTS, F3.2

CPC

One use case for CPC


Some proposals of work items for ETSI

Technical standard on "Cognitive Pilot Channel"

☺☺ CPC concept needs some implementation studies

☺☺ Complementary to P1900.4 work on CPC functionalities and related protocols


Some proposals of work items for ETSI

• What additional essential parameters for cognitive terminals compared to classical radio terminals?

• What additional essential parameters for cognitive base stations?

Preparation of Harmonized Standards for Cognitive Radio systems

• Elaboration of HS for cognitive radio terminals

• Elaboration of HS for cognitive radio base stations

• Elaboration of HS for Radio Enabler

ANY QUESTION?
