As RSRQ combines signal strength as well as interference level, this measurement value provides additional help for mobility decisions. RSRP, RSSI, and RSRQ are three important indicators that help determine the strength and quality of your wireless signal in both 4G and 5G networks. RSSI is the total received wideband power including all interference and thermal noise. RSRQ is the ratio between the RSRP and the Received Signal Strength Indicator (RSSI), and depending on the measurement bandwidth, means the number of resource blocks. The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision. RSRQ N × RSRP/ (EUTRA carrier RSSI), As you see from the definition of RSSI, RSSI contains all sorts of power including power from co-channel serving & non-serving cells, adjacent channel interference, thermal noise, etc. This study aims to evaluate the quality of video streaming over the 4G LTE network based on the quality of experience parameters of RSRP, RSRQ and. The results indicate a high level of spatial correlation and a sufficient level of confidence, which are needed to ensure consistency and repeatability of these measurements. RSRQ stands for Reference Signal Received Quality. It can therefore only be measured in the OFDM symbols carrying reference symbols. RSRQ is defined as (N x RSRP)/RSSI in 3GPP 36.214, where N is the number of RBs over the measurement bandwidth. The known indicators RSRP, RSSI, and RSRQ are analyzed spatially, over time, and for different driving conditions. RSRP stands for Reference Signal Received Power and is a variation of RSSI measurement. The RSRP is the average of the power of all resource elements which carry cell-specific reference signals over the entire bandwidth. This measurement of the signal strength of an LTE cell helps to rank between the different cells as input for handover and cell reselection decisions. The RSRP is comparable to the CPICH RSCP measurement in WCDMA. RSRP The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad).
