It sends a non-negative value ranging from 0 to 34 and each of these values are mapped to a specific range of real RSRQ value as shown in the following table from 36. Code reference • Reception of PSCCH at UE PHY • RSRP computation. Notably, cmWaves fall within the frequency range of 100 to 1000 GHz, offering significantly. •RSRP (dBm) = RSSI (dBm) -10*log (12*N) where RSSI = Received Signal Strength Indicator N: number of RBs across the RSSI is measured and depends on the BW • Significance : - RSRP is the most basic of the UE physical layer measurements and is the linear average power (in. This can happen immediately after the device is switched on, or it can happen after inter-system cell reselection from LTE. and simulation. RSRQ= -12.
