![]() If RSRP is -60 dBm and the cell is fully loaded (20MHz) and the UE is experiencing 10dBm power from a Neighbour cell operating at same frequency RSSI measured -60 dBm + 30.72 dBm +10 dBm = -19.98 dBm. ![]() Where N represents number of resource block.īy using above equation RSSI can be calculated as: Under full Load condition the RSRP (dBm)= RSSI – 10*log (12*N) RSSI = Serving Cell Power + Neighbour Co-Channel Cells Power + Thermal Noise RSSI is also a power and its measurement unit is dBm The RSSI is used in the calculation of RSRQ in LTE system. RSSI is defined as the total received wide-band power measured over entire bandwidth by UE. Received Signal Strength Indicator ( RSSI): RSRP, RSRQ, RSSI ) are included in the RRC Information Elements (IEs) carries. Reference Signal Received Quality (RSRQ).Received Signal Strength Indicator (RSSI).Reference Signal (RS) measurements are further classified into three measurement parameters as given below: In 5G new radio (NR) system, reference signal measurement are used to perform cell selection, cell reselection and handover etc.
