Path loss and transmit power calculation for a user equipment

An apparatus of a user equipment (UE) for wireless communication, comprising:

• a first interface configured to 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;
• a processing system configured to calculate a path loss and a transmit power, for each antenna port of the plurality of antenna ports, using an RSRP measurement corresponding to each respective antenna port;
• and
• the first interface or a second interface configured to output a sounding reference signal (SRS) via a select antenna port of the plurality of antenna ports using the transmit power associated with the select antenna port.

A method of wireless communication performed by a user equipment (UE), comprising:

• obtaining 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;
• calculating a path loss and a transmit power for the plurality of antenna ports using a worst RSRP measurement of the plurality of RSRP measurements;
• and
• transmitting a sounding reference signal (SRS) using the transmit power.
