![]() When RSRP value is reported back, its not that UE send the actual measurement right away. Please note, that RSRP can be based upon the cell specific Reference signal transmitted by only the first antenna port or RSRP can be based upon the cell specific reference signal transmitted by first and second antenna ports Reference point for RSRP measurement is the antenna connector of the UE.Power measurement is based upon the energy received during the useful part of the OFDMA symbol and excludes the energy of the cyclic prefix.The average RSRP is taken in linear units.RSRP is the average power received from a single cell specific Reference Signal Resource Element Estimate the Path Loss for power control calculations.If analogy helps RSRP is the equivalent tof the UMTS CPICH Received Signal Code Power (RSCP). RSRP measurements will be used by the UE at all times. RSRP is the water and wine for a UE, from the moment a UE is powered-on to the point it goes into idle mode. Reference signals are equivalent to what Pilot signals do in UMTS. How a UE communicates ? : Measurements and SignalsĪmong various measurements, the three most important ones are :Īll these are derived from Reference signals.
