What is RSRP/RSRQ?

What is 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. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ.

What is the difference between SINR/Snr/SRP and RSRQ?

SINR/SNR – The signal-to-noise ratio of the given signal. RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm (bad). RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB (bad) to -3dB (good).

What is rsrsrq in eNodeB?

RSRQ is a calculated value from RSRP and RSSI . As RSRQ is a ratio of two signal powers with same same unit ( i.e. dBm) it uses dB as a measurement unit. Similar to RSRP , UE reported an integer value to eNodeB and its range is from 0 to 34

What is the formula for RSRQ?

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.
