Operation

3.2 Nokia UltraSite WCDMA BTS architecture

In the uplink path, the BTS receives signals from the UE; in the downlink path,the BTS sends signals to the UE. Uplink and downlink signals travel through theair interface (Uu) on different frequencies, the higher frequency carryingdownlink signals.

Uplink path

The antenna picks up a signal from the UE through the air interface. The antennapasses the signal to the optional MHA and Bias-T units and further on to theantenna connectors at the BTS cabinet top. The signal then goes through theAntenna Filter Unit (WAF) to the Transmitter and Receiver Unit (WTR).

The WTR unit converts the received signal to a digital format and sends it to thebaseband unit for further processing.

The signal passes the Summing and Multiplexing Unit(s) (WSM) which providesthe so-called pooled WSP capacity feature and is then routed to the allocatedWSP unit.

The WSP sends the processed signal to the Application Manager Unit (WAM)which passes the signal to the ATM Cross-connect Unit (AXU). The AXU unitsends the signal to the Interface Unit (IFU) which then passes the signal throughthe Iub interface to the RNC.

Downlink path

The RNC receives a signal from the network and sends the signal to the IFU unitthrough the Iub interface. The IFU unit passes the signal to the AXU unit. TheAXU unit then switches the signal to the allocated WAM unit for ATMtermination. The WAM unit unpacks the ATM frame and sends the signal to theallocated WSP unit for digital processing. The WSP unit sends the processedsignal to the WTR unit via the WSM unit(s).

In the WTR unit, the signal is converted from digital to analog and modulated tothe carrier frequency. The WTR unit then sends the signal to the Power AmplifierUnit (WPA) through a WIC unit. WPA amplifies the TX RF-signal to the finalRF-power level. The WAF unit sends the signal to the antenna connectors at theBTS cabinet top. The signal then goes through the optional Bias-T and MHAunits to the antenna which passes the signal through the air interface to the UE.

4 Transmission

4.1 Transmission interfaces

Transmission functionality is integrated in the WCDMA BTS. The transmissionbetween the RNC and the BTSs (Iub interface) is based on ATM. It is possible touse the already available PDH or SDH based transmission networks (for exampleE1, STM-1 and so on). The WCDMA ATM Iub traffic can be transported overthe existing transmission systems by using inverse multiplexing (IMA). IMAcombines 2/1.5/6.3 Mbit/s connections to one ATM connection, and vice versa.There is no immediate reason to change or modify the existing access network,except for the necessary capacity upgrades due to increased traffic. The RAN(BTS-RNC) transmission can be based on star, chain, tree and loop topologies.

The physical transmission links can be shared between the WCDMA generatedtraffic and the second generation mobile traffic and fixed traffic.

Each Nokia UltraSite WCDMA BTS has an integrated ATM switch, called theATM Cross-connect (AXC) Node, for communication between the sectors insidethe BTS, towards the RNC, and towards other BTSs. The AXC is constructed ofone AXU unit and 1 to 5 Interface Units (IFUs).

The AXU unit performs the main ATM functionality for the communicationwithin the BTS, and provides the connections to other network elements. TheIFUs provide the physical connection to the network.

The IFUs currently available for Nokia UltraSite WCDMA BTS are the IFUs A/C/D and E. They support the following transmission interfaces respectively:

. E1/JT1

. STM-0/STM-1

. E1

. Nokia Flexbus

5.1 Local management

Element manager SW is used for managing Nokia UltraSite WCDMA BTScommissioning, supervision, maintenance, and testing, as well as transmissionconfiguration. The element manager SW includes Nokia WCDMA BTS Manager(see figure below) and AXC Manager for transmission management. They areintegrated so that the physical interface (cable and connectors) are the same butthere are two different applications running on the PC.

The Manager PC is connected to the BTS by means of an Ethernet connection.



21 (86)

Related software

Figure 8. Nokia WCDMA BTS Manager

Both Nokia WCDMA BTS Manager and AXC Manager run in NT, Windows 95,Windows 98 or Windows 2000 environment.

5.2 Configuration management

Once the BTS is in normal operation, a polling process is used to check thepossible changes in the BTS configuration. The information in the HW databasechanges when units are added or removed from the BTS.




If the initially detected units do not respond to the normal autodetection polling,they are reported to be faulty.

5.3 Software updates

Nokia UltraSite WCDMA BTS can store two SW packages in its memory. SWcan be loaded either locally with the element manager SW, or remotely from theRNC or Nokia NetAct" (via the RNC).

Local SW downloading is typically done only when Nokia NetAct" connectionis missing, that is during the commissioning. Nokia UltraSite WCDMA BTS SWcan be downloaded as a background operation without interrupting the BTSoperation. The new SW can be activated at any time suitable for the operator.

Only downloadable SW is used in Nokia UltraSite WCDMA BTS. The SW canbe downloaded and updated from Nokia NetAct". This procedure is centralised,which means that several BTSs can be upgraded with the new SW eithersimultaneously or one by one.

Nokia UltraSite WCDMA BTS keeps the current and a previous SW package inits flash memory. In the case of, for example, a power cut, the current SWpackage will be brought into use from the flash memory in a few seconds.

5.4 External alarms and controls

The BTS inputs and outputs can be configured and tested locally on the NokiaUltraSite WCDMA BTS site with the element manager SW. There are 24 user-definable external inputs and 6 user-controllable outputs available. These can befreely configured to support different observation or control needs at the BTSsite.

In normal operation, the BTS's external alarms and control outputs are managedfrom Nokia NetAct" after they have been configured.

Units

7.2.1 Transmitter and Receiver unit

Note

The new Nokia UltraSite WCDMA BTS Optima Compact Outdoor and SupremeIndoor use only Rel2 units.

Transmitter and Receiver unit, WTRA (Rel1)

On the transmit side, the WCDMATransmitter and Receiver unit (WTR) receivesdigital data from the Signal Processing unit (WSP) via the Summing andMultiplexing unit (WSM) and performs modulation and up conversion of thecarrier, which is amplified by the Power Amplifier (WPA). On the receive side,the WTR performs channel selection and down conversion for the selectedcarrier. The received signal is digitised and connected to the WSP via the WSM.The main features of the WTRA unit are:

. Two receivers (RX1 and RX2) and one transmitter (TX1)

. RX band 1920-1980 MHz and TX band 2110-2170 MHz (duplexseparation of 190 MHz)

. Implementation from baseband to the RF in TX and from RF to basebandin RX

. Digital IF sampling with 61.44 MHz clock

. Internal VCXO for high quality clock reference

Transmitter and Receiver unit, WTRB (Rel2)

The Rel2 WTR unit (WTRB) offers double the capacity of the Rel1 WTR unit(WTRA). It contains two separate TRXs that can be used independently fromeach other. TRXs of the WTRB can operate on the same frequency or, ifnecessary, on different frequencies. The unit offers also combined output (TX1 +TX2).

WTRAs and WTRBs can be used in the same cabinet. The features of the WTRBare the following:




. Two independent diversity receivers, each consisting of two RX pathsresulting in a total of four RX paths (RXM1, RXD1, RXM2 and RXD2)and two independent transmitters (TX1 and TX2)

. RX band 1920-1980 MHz and TX band 2110-2170 MHz, duplexseparation of 190 MHz (WTRB can support also variable duplexseparation)

. Implementation from baseband to RF in TX and from RF to baseband inRX

. IF sampling with 61.44 MHz clock (RX)

. Internal VCXO for high quality clock reference

7.2.2 Power Amplifier unit

The Power Amplifier unit (WPA) provides linear amplification to WCDMAcarriers with a constant power gain of 40 dB (WPAA/B) or 43 dB (WPAC/D).The WPAA/B/C/D amplifier is capable of supporting up to four adjacent carriersin any 20 MHz section on the whole 60 MHz WCDMA allocation. There are 30W WPA units (WPAA/B/I/J) and 54 W WPA units (WPAC/D).

The EEWPA (WPAI/J) is an efficiency enhanced version of the 30 W WPA. TheEEWPA supports up to two adjacent carriers in 10 MHz bandwidth on the whole60 MHz WCDMA allocation and can be used in all Rel2 HW configurations.

To increase output power, two power amplifiers can be combined parallel byusing the Input Combiner Unit (WIC) at the WPA input and the Output CombinerUnit (WOC) at the WPA output. 54 W versions cannot be combined parallel.

All versions of the WPA and EEWPA can be used with a Wideband PowerDivider unit (WPD) to divide output power to more than one sector (ROCconfigurations).

Note

The new Nokia UltraSite WCDMA BTS Optima Compact Outdoor uses only theDC version of the WPA unit.



47 (86)

Units

7.2.3 Input Combiner

The Input Combiner (WIC) unit connects output signals from the WTR unit to theWPA inputs.

7.2.4 Output Combiner

The WAF is capable of feeding operating power to two Nokia UltraSite WCDMAMasthead Amplifier (MHA) units.

7.3 Baseband units

Note

The new Nokia UltraSite WCDMA BTS Optima Compact Outdoor and SupremeIndoor use only Rel2 units.

7.3.1 Summing and Multiplexing unit

The Wideband Summing and Multiplexing unit (WSM) sums the TX signalsfrom the Signal Processing units (per antenna) or other WSMs to its own TXsignal, and routes and sums the TX data to the appropriate WTRs. RX data isrouted through the same path, but without summing. The operating principle isthe same for both WSMA and WSMB.




Rel1 (WSMA) and Rel2 (WSMB) WSMs

In Rel2 the WSMA unit is replaced with the WSMB because the WTRB doublesthe capacity offered by the WTRA unit. This means that the data throughput ofthe WSMA has to be doubled for it to be capable of handling WTRBs. TheWSMB provides this capacity.

7.3.2 Signal Processing unit

The Signal Processing unit (WSP) performs RX and TX code channel processing,channel coding, and channel decoding functions. Summing of the TX codechannels is performed for the code channels processed in the unit. The operatingprinciple is same for WSPA and WSPC.

Rel1 (WSPA) and Rel2 (WSPC) WSPs

In Rel2 WSPC replaces the WSPA. It offers double the capacity of WSPA, that is64 HW channels. Rel1 and Rel2 WSP units can be used in the same cabinet fromrelease RAN'04 onwards.

7.3.3 Application Manager unit

The Application Manager unit (WAM) takes care of the control functions inNokia WCDMA BTSs, such as BTS initialisation, configuration, and O&Mfunctions. The unit also performs transport channel processing, ATM processing,telecom frame protocol handling and logical resource management.

One of the WAM units in the BTS acts as the master O&M unit and the other oneas the telecom master unit.The O&M master WAM takes care of the BTS powerup control and the control and maintenance functions during run time. Thetelecom master WAM operates as the main signalling counterpart to serve theRNC. All other WAMs perform lower level O&M and telecom functions. If thereis only one WAM unit in a BTS, it takes care of both master functions.

8 GSM co-siting

When utilising existing BTS sites the compatibility of Nokia UltraSite WCDMABTS with existing Nokia BTSs is a major issue. Nokia has designed NokiaUltraSite WCDMA BTS so that it can be installed as easily as possible to anexisting site. The figure below illustrates the principle of how this can beachieved.



59 (86)

GSM co-siting

Figure 23. Combining WCDMA BTS and GSM/EDGE BTS to the same antennafeeder with diplexer and Bias-T

Compatibility has been considered for the following areas:

Mechanics

Nokia UltraSite WCDMA BTS Optima Indoor and Supreme cabinets havesimilar space requirements as Nokia Talk-family and Nokia UltraSite EDGEBTSs have. Also, their floor installations share the same fixing points. OptimaCompact Outdoor is slightly wider.

Power system

When Nokia UltraSite WCDMA BTSs are installed to existing GSM BTS sites,the same kind of connections and power supplies can be used.

Existing alarm connections, for example fire alarm and door alarm, can beconnected to Nokia UltraSite WCDMA BTS as well. Customer-specific alarminput and control output electrical specifications are the same, which allows fullinterchangeability between connections.

Nokia UltraSite Support cabinet can support both Nokia UltraSite EDGE andWCDMA BTSs.

Antennas

To minimise the work of adding WCDMA antennas to GSM BTS sites, a part ofthe existing antenna infrastructure can be reused.

A diplexer is an effective way to add Nokia UltraSite WCDMA BTS to theexisting site if the additional loss can be tolerated in the antenna line. Actuallosses are dependent on the combination but for example in the GSM 900 /WCDMA case typical loss is less than 0.5 dB. Nokia will supply diplexers to allneeded combinations.

The Bias-T, with or without VSWR monitoring of the antenna line, supplies theMHA with a DC voltage from the BTS.

GSM co-siting

Figure 24. Co-sited Nokia UltraSite WCDMA and Nokia Talk-family BTSs

Transmission

Transmission of the existing sites can be efficiently utilised when WCDMA isadded. This has been a very important transmission design criteria for NokiaUltraSite WCDMA BTSs.

Nokia UltraSite WCDMA BTS is capable of connecting to the existing PDH/SDH networks. If there is excess capacity or possibility to increase capacity inthose networks, Nokia UltraSite WCDMA BTSs are able to use it.

The same kind of physical interfaces will be used in both GSM and WCDMAsystems. This will allow easy connection to the existing transmission.

Transmission capacity can be shared by using fractional E1s or circuit emulation.




Commissioning, integration and management

The element manager SW provides support for the whole Nokia UltraSitesolution, for example WCDMA and EDGE BTSs. This allows personnel to docommissioning and integration on site using one laptop PC. They only usedifferent application software for the different technologies.

9.5 Power consumption

The power consumption of Nokia UltraSite WCDMA BTS depends on thefollowing values

. Nominal input voltage

. Nominal power consumption situation at +25° C

Note

If DC power is used, the corresponding values are approximately 5% smaller.



71 (86)

Technical data

Note

'Typical values' assumption includes one E1 transmission card. MHAs andcabinet heaters are not included in the BTS power consumptions. 'Maximumvalues' assumption includes MHAs and full transmission with radio links andoptical transmission units (for example, 3 x IFUE and 2 x IFUC in SupremeBTS).

Caution

In the commissioning phase, the Power System Manager (PSMMan) or IBBUmanager may set a limit to charging the batteries, and thus affect the batterycharging power consumption. When an IBBU cabinet is commissioned using 16A limitation, this means a 900 W battery charging power consumption. Thefactory default setting in CU is 10 A, which means a battery charging powerconsumption of about 540 W . If a 50 W WPA is used (for IBBU cabinet), themaximum power consumption is 6670 W AC.

Note

If you install LTE units in the IBBU cabinet, the power consumption increases.110 W/LTE for the LTE outputs 1-3 is the maximum power consumption. For theLTE output 4, 390 W is the maximum power consumption. Maximum heat load is240 W for the whole of the LTE space.

Note

The power calculations in the following tables indicate the actual power inputfrom the electrical network and include the operating efficiency of the powersupply unit.

9.10 Iub accuracy requirement

To meet the BTS Air interface accuracy requirement +/- 0.05 ppm (set by 3GPP),the Iub interface must meet the long-term accuracy of +/- 0.015 ppm. This kind ofaccuracy is attained if the network master clock (PRC) fulfills the ITU-Trecommendation G.811 and the synchronisation of the network is correct. Themaximum jitter/wander of the Iub interface is specified in the ITU-Trecommendation G.823.

Another possibility is that the BTS master clock reference comes via the AXUreference clock interface. The Iub accuracy requirement above also applies for theAXU reference clock interface.
