What is RSRP and RSRQ in LTE?
RSRP and RSRQ Measurement in LTE. RSRP and RSRQ are key measures of signal level and quality for modern LTE networks. In cellular networks, when a mobile moves from cell to cell and performs cell selection/reselection and handover, it has to measure the signal strength/quality of the neighbor cells. In LTE network,…
What is the difference between RSRQ RSSI and SINR?
RSSI is a pure wide band power measurement, including intracell power, interference and noise. The reporting range of RSRQ is from -3 dB to -19.5 dB. SINR – Signal to Interference plus Noise Ratio. SINR is the reference value used in system simulation and can be defined as: Wide band SINR.
What is SINR in LTE?
LTE SINR Definition. SINR is defined as: S: indicates the power of measured usable signals. Reference signals (RS) and physical downlink shared channels (PDSCHs) are mainly involved. I: indicates the average interference power – the power of measured signals or channel interference signals from other cells in the current system.
What does rsrsrq mean on a cell line?
RSRQ – Reference Signal Received Quality. 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 re-selection decision.
What is the reporting range of RSRP?
The reporting range of RSRP is defined from -140 dBm to – 44 dBm with 1 dB resolution. The mapping of measured quantity is defined in the table.

What is the difference between rsrsrp and UE?
RSRP is the average received power of a single RS resource element. UE measures the power of multiple resource elements used to transfer the reference signal but then takes an average of them rather than summing them.
