Hi,
We did the following tuning for L800 10M Cells to enhance DL Power of PDSCH RE.
Before (pMAX = 43dBm and dlRsBoost = 0dBm ) --> RS Power = 15.2dBm and PDSCH Power = 15.2dBm
After (pMAX = 46dBm and dlRsBoost = -3dBm ) --> RS Power = 15.2dBm and PDSCH Power = 18.2dBm
With the new setting, RS Power has not changed (15.2dB) and PDSCH RE power increased by 3dB and there was an improvement of CQI, Avg MCS PDSCH trans, Reported MIMO Rank2 Ratio and DL User Throughput.
But, the Intra frequency HO attempts increased and the Intra frequency HO SR degraded as shown in below plot.
Since our mobility strategy is totally based on RSRP (a3TriggerQuantityHO=RSRP) and RSRP is calculated based on RS Power for coverage handover, which in our case remains unchanged, how to explain the increase of Intra frequency HO attempts ?
