1 xCEM Improvements vs. iCEM


Why xCEM ?

xCEM is next generation of Channel Element Module board for Alcatel-Lucent macro Node-B, substituting existing iCEM

R99, HSDPA & HSUPA support provided on one module

Actual capacity increase even more significant with Multi-mode BBU in UA06

Compatible with existing macro iBTS cabinets and modules

Second form factor will also be available for d-NodeB 2U product

xCEM replaces current iCEM module and is introduced with new ordering code

No End Of Life declared on existing iCEM

5 New Features related to xCEM

UA05.1.1


#33481 E-DCH Signalling Channels Power Control

Power control for AGCH is based on CQI

AGCH is only sent by the serving radio leg

Since HS-DSCH is the DL RAB for HSUPA CQI is always available

Power is updated each HSDPA TTI = 2ms

Initial Tx power PCQI is given by a hard-coded LUT using the CQI and the mean square error of the CQI, i.e. PCQI = LUT(CQI, MSE(CQI))

MSE takes the channel variations into account

OMC Parameter eagchPowerOffSet allows further control of the Tx power

This offset is a positive or negative constant offset across all CQI values

Parameter range –45 dB to +65 dB

Final AGCH Tx power PAGCH is then given by

PAGCH = PCQI + eagchPowerOffSet

Save DL resources, improve performances!Save DL resources, improve performances!


Power control of E-AGCH channels

E-AGCH power control becomes critical as more than one E-AGCH and 2 ms TTI will be supported in UA06.

Moreover larger HSUPA mobile penetration will be available

E-AGCH power control becomes critical as more than one E-AGCH and 2 ms TTI will be supported in UA06.

Moreover larger HSUPA mobile penetration will be available

Significant power saving


#34102 Flexible HSDPA modulation usage versus codes

Enhancements

Modulation 16QAM is preferred

when number of remaining

codes is limited.

Increase the transport block size

in order to use remaining unused

codes by preferring QPSK

modulation

High benefits for cat 8 UE

Implementation

Define new TFRC tables

according to the number of

available HS-DSCH codesFor the same Transport burst size, QPSK modulation is more robust but requires more codes

Higher throughput in code limited situation and for category 8 handsets
