Section: A.20 Use case of RSRQ
Content: E-UTRAN RSRQ measurement can be used to calculate signal quality distribution. According to signal quality dstribution and other measurements like AOA, UE Rx-Tx time diffrence, the general signal quality information of cells can be learned, so that interference heavy area can be found more easily by driving test. Also it can be used to evaluate user satisfaction to some extent. So it is necessary to define the RSRQ measurements. In order to reduce the transmission bandwidth requirement, according to network optimization experience, 1dB granularity of measurement is enough.
