Abstract: A user equipment (UE) may obtain a plurality of reference signal received power (RSRP) measurements, each RSRP measurement of the plurality of RSRP measurements corresponding to an antenna port of a plurality of antenna ports associated with the UE. The UE may calculate a path loss and a transmit power for the plurality of antenna ports based on a worst RSRP measurement of the plurality of RSRP measurements, and may transmit a sounding reference signal (SRS) based on the transmit power. This may reduce a likelihood that a network node incorrectly estimates the channel conditions experienced by the UE and may improve the channel estimation capabilities of the network node.
