1. A method for a base station, the method comprising:
receiving, from a user equipment (UE), an indication of a UE capability based on an antenna structure of the UE comprising multiple antenna panels, wherein the indication of the UE capability indicates whether the UE supports coherent transmission, non-coherent transmission, or partial coherent transmission for each of the multiple antenna panels and across each of the multiple antenna panels;
measuring sounding reference signal (SRS) transmissions corresponding to the multiple antenna panels of the UE, wherein measuring the SRS transmissions comprises measuring a reference signal received power (RSRP) of the SRS transmissions from each of the multiple antenna panels to determine a pathloss for power control;
based on the UE capability and the SRS transmissions, determining one or more uplink (UL) precoders and a corresponding UL rank, wherein the one or more UL precoders includes a polarization co-phasing factor, an antenna panel co-phasing factor, and a combining weight for antennas for a same polarization; and
transmitting an indication of the one or more UL precoders and the UL rank to the UE.
