Abstract
A user equipment (UE) is arranged to send an uplink power reference signal to an enhanced Node B (eNB) associated with multiple reception points (RPs), to receive identification of an RP set and a downlink reference signal power level, to determine a path loss estimate for each downlink reference signal received from RPs of the RP set, to determine an uplink power level that is a function of the path loss estimates determined for the downlink signals received from the RPs of the RP set, and to use the determined uplink power level during communication with the multiple RPs.
