UE transmitted power measurement is useful to analyze coverage quality of each cell and do troubleshooting of blind spot by the distribution of this measurement together with other measurements, such as P-CCPCH RSCP measurement. It is also used to evaluate power control performance and decrease UE transmitted power as possible with QoS is guaranteed for the purpose of energy saving. These questions are determined by the ratio of the number of larger or less than threshold to the total number of it and the threshold is configurable. So it is necessary to define UE transmitted power measurement.

According to network optimization experience, the granularity of measurement 3dB is enough to do trouble shooting of blind spot and evaluation of power control.
