How To Calculate Rsrp 2n92j

How to calculate RSRP:

Reference Signal Received Power (RSRP) is defined as the linear average over the power contributions (in [W]) of the resource elements (REs) that carry cell-specific reference signals within the considered measurement frequency bandwidth.

S. 

RSRP is the average received power of a single RS resource element

RSRP 

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.



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 – RSRP mapping 3GPP TS 36.133 V8.9.0 (2010-03)



RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors



RSRP levels for usable signal typically range from about -75 dBm close in to an LTE cell site to -120 dBm at the edge of LTE coverage.

For RSSI (Received Signal Signal Strength Indicator):

RSSI (Received Signal Strength Indicator) is a parameter which provides information about total received wide-band power (measure in all symbols) including all interference and thermal noise. RSSI is not reported to e-NodeB by UE. It can simply be computed from RSRQ and RSRP that are, instead, reported by UE.

RSSI = wideband power = noise + serving cell power + interference power

SINR Definition SINR is the reference value used in the system simulation and can be defined: 1. Wide band SINR 2. SINR for a specific sub-carriers (or for a specific resource elements)

Where S: original signal I: Interference N: Noise
