I'm trying to optimize the DL open-loop PC in a 3G Huawei network RAN10.
I found in the Huawei documentation the following recommendation:
The values of PSCH transmit power and SSCH transmit power must not be too large. The parameter values can be adjusted based on the measurement in the actual environment, so that the transmit powers of the synchronization channels satisfy the UE receiving demodulation requirement. The transmit power should be just enough to ensure that a UE can implement fast synchronization in most areas of the cell edge. Neither P-SCH nor S-SCH comes through channel code spectrum spreading, so they produce more serious interference than other channels, especially for near-end UEs.
Anyone know, which measurements are meant here. Unfortunately I can't find more informations about this topic.
Many thanks in advance!
The related counter I found is :
VS.RAB.Loss.CS.RF.ULSync
"UL synchronization failure leads to abnormal release of a link. This problem is usually due to poor coverage, which may be further due to missed neighboring cell configuration or small handover area. As a result, the UE shuts down the transmitter unexpectedly, or the UL demodulation is out of synchronization."
Great forum here! ;)
