DESCRIPTION

LTE RSRP Notes

TRANSCRIPT

RSRP:Reference signal received power (RSRP), is determined for a considered cell as the linear average over the power contributions (in [W]) of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth.Note: Different from GSM or TD-SCDMA systems, TD-LTE systems have multiple subcarriers multiplexed. Therefore, the measured pilot signal strength is the RSRP of a single subcarrier (15 kHz) not the total bandwidth power of the frequency.The RSRPs near a cell, in the middle of a cell, and at the edge of a cell are determined based on the distribution of signals on the entire network. Generally, the RSRP near a cell is -85 dBm, the RSRP in the middle of a cell is -95 dBm, and the RSRP at the edge of a cell is -105 dBm.Currently, the minimum RSRP for UEs to camp on a cell is -120 dBm.
