1. A method for wireless communication, comprising:
transmitting a request to a user equipment (UE) for the UE to transmit a set of sounding reference signals (SRSs);
receiving the set of SRSs in accordance with the request, the set of SRSs comprising at least two beamformed signals associated with a phase shift parameter;
identifying, based at least in part on the phase shift parameter associated with the at least two beamformed signals, an antenna port precoder configuration; and
transmitting an indication of the identified antenna port precoder configuration associated with the phase shift parameter to the UE for communication.
