Performance
The MC-TRX output power depends on the number of carriers configured per
module.
MC-TRX provides flexibility for operators:
capacity: power distributed over a high number of carriers.
coverage: power focus on a low number of carriers, with higher power per carrier.
Easy implementation by SW adaptation from the OMC.
The output power can also be shared between two different radio standards.

An MC-TRX module provides a certain amount of physical output power. Its capability to distribute the total
output power to all carriers gives operators the highest flexibility to convert the radio transmitted powerto coverage or capacity, and this is done by SW adaptation only from the OMC.TOC= Top of Cabinet

Dynamic Power Allocation (1/2)
Because it is unlikely that all carriers of the MC-TRX will transmit with
maximum power simultaneously, the Dynamic Power Allocationconsists in allocating the unused power according to the needs toother carriers with higher traffic load.
The value of additional powers depends on the number of TREs in theMC-module.

Dynamic Power Allocation (2/2)
If the BTS transmission is not possible on all the TRXs of the MC
module at the required power levels for a given radio burst due tothe maximum emission power for the Power Amplifier beingexceeded, then a power reduction in the BTS shall be applied bydecreasing priority on:
The emission power of all the 8-PSK bursts shall be reduced by samereduction factor (in %), except for the 8-PSK bursts to be transmitted withthe BCCH frequency
If the first step is not sufficient then the emission power of all the GMSKpower controlled channels shall be reduced by the same form factor (in %),except for the GMSK bursts to be transmitted with the BCCH frequency.
MC-TRXOutput Power
If the two steps dont solve the situation, a last solution (as adefense solution) consists in reducing the power of all theremaining bursts by a same form factor (in %). This situation shouldnever happen in a properly configured network.
The reduction factor is calculated by the BTS and applied immediately according to an algorithm that takes
into account the number of TRXs configured on the MC-TRX.

TRX Dynamic Power Saving
Already implemented in B10, the TRX Dynamic Power Saving
feature consists in switching off the Power Amplifier bias of a TRX assoon as several consecutive timeslots are unused in DL on this TRX.This feature allows a significant reduction of power consumption ofthe BTS.
This feature is not directly applicable to MC-TRX modules, due tothe fact that for a given TS, significant power consumption gains canonly be reached if there is no DL transmission on all the TRXs of theMC module.
MC-TRXOutput Power
TRX Dynamic Power Saving
The TRX dynamic power saving feature (with some periods of complete switch-off of the PA bias of themodule) is not directly applicable on the TRXs of MC modules, due to the specific architecture of MCmodules.
For a given TS, due to the fact that significant power consumption gains can only be reached if there is noDL transmission on all the TRXs of the MC module (on the same TS), the interest of the TRX dynamic powersaving feature within MC modules is limited.
As a consequence and to simplify, the TRX dynamic power saving feature is not directly applicableto MC modules in B11. This feature will only be supported on the Single and TWIN TRM modules.

Benefits of the MCPA Introduction
A better power efficiency:
One Power Amplifier can handle up to 6 carriers in parallel (in a pure GSMconfiguration).
Suppression of the wideband combiner stage (at least 3 dB loss = 50% of RFpower loss per combiner stage).
This also leads to a reduction of the power consumption.

4x16W = 64Wat ToC
4x45W = 180Wat module output
4x16W = 64Wat ToC
4x21W = 84Wat module output
Power Consumption Efficiency Comparison of MC-TRX vs. TWIN TRX
The conventional approach via a single carrier power amplifier needs 4x45W = 180W of RF output power onthe module side to provide 4 GSM carriers in one sector. Due to the loss in the necessary widebandcombiner, the output at Top of Cabinet (ToC) is 4x16W = 64W of RF power in this sector.
To reach the same result, an MC-TRX needs 4x21W = 84W of RF output power on the module side. Becausethere is no combining needed, the desired RF output power of 4x16W=64W is also reached at Top ofCabinet.

1.2 How Does It Work? [cont.]
Cell Frequancy Span
An MC-TRX covers a limited frequency bandwidth of 20 MHz called
MCPA frequency span (which is an HW capability) among: 35 MHz in GSM 900 MHz
75 MHz in GSM 1800 MHz
This bandwidth of 20 MHz is constant in an MC-TRX and can be shiftedwithin 35 or 75 MHz.
The whole set of TRXs of the same band and of the same cell willnot use a frequency window higher than the frequency span
reported by the BTS.
The check of frequency span at the OMC is only done if the OMC knows if there is an MC-Module in a sector
mapped on the cell (and so, only after OMC/BTS HW audit). That means the cell exists and is alreadymapped to a sector. In this case, the TRX has the RSL information. The test is done at cell level even incase of cell shared, and if there is at least one MC-Module in one sector.
In B11, we support only so-called normal cell frequency span, i.e. the whole set of TRXs (of the sameband and of the same cell) use a frequency window smaller than the frequency span reported by the BTS.
The check itself is therefore quite simple:
1. For the concerned band, look for the smallest frequency and for the highest frequency.
2. Compute the difference between them and get the correspondence in MHz.
3. Compare the result with the frequency span (also called PA RF BW) received in OMC/BTS HW audit.
The BTS has to check the Bandwidth per MC-module when it receives the radio configuration: if theBandwidth is larger than the MCPA frequency span (also called PA RF BW), the BTS sends an alarm to allinvolved MC-modules.
