UE timeslot ISCP measurement is useful to analyze coverage quality of each cell and do troubleshooting of blind spot together with other measurements, such as P-CCPCH RSCP measurement. So it is necessary to define UE timeslot ISCP measurement.

According to network optimization experience, the granularity of measurement is 1dB when UE_TS_ISCP_LEV is less than 57, and there are very few UE_TS_ISCP_LEV results that is larger than and equal to 57, so one measurement is defined for it. From these measurements, it is easy to get the ratio of the number of UE_TS_ISCP_LEV that is larger than threshold to the total number of it, and the threshold is configurable according to use cases, such as cell coverage analysis, channel estimation analysis etc.
