Narrowband N = 62 Sub Carriers (6 Resource Blocks).It must to bemeasured over the same bandwidth: In the procedure of handover, the LTE specification provides the flexibility of using RSRP, RSRQ, or both. RSRQ –Reference Signal Received Quality:Quality considering also RSSI and the number of used Resource Blocks (N) RSRQ = (N * RSRP) / RSSI measured over the same bandwidth.RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal.The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision.
It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband.Ī minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ RSRP –Reference Signal Received Power:RSRP is a RSSI type of measurement, as follows there are some definition of it and some details as well.
