UE Measurement- Reference Signal Received Power (RSRP)

Reference Signal Received Power (RSRP) is measured by a UE during the procedure of cell selection, cell reselection in idle mode, and handover, and is an important factor in decision making.

RSRP linear measures the average power of resource elements over cell-specific reference signals. When the eNB configures the measurement, it usually gives the measurement bandwidth.

The measurement is usually carried on antenna port 0 of the eNB, although an eNB may use multiple antennas, in which case there are reference signals transmitting from each antenna port. If antenna port 1 can be reliably detected, it may also be used.

If there are multiple receive antennas at the UE, the received power is averaged over all branches of the receive density. In other words, RSRP is a good indication of average received RS power.

RSRP is an important parameter in coverage indication and site acceptance, and the performance of cell selection, cell reselection and handover.
