Abstract
An apparatus, e.g., a UE, for selecting an uplink precoder using a non-codebook-based procedure is disclosed. The UE may receive, from a base station (BS), at least one downlink reference signal comprising at least one DMRS via at least one downlink channel. The UE may measure, based on the at least one downlink reference signal, the at least one downlink channel. The measuring may be based at least in part on the at least one DMRS. The UE may select at least one first uplink precoder for at least one uplink channel corresponding to the at least one downlink channel based on the measuring of the at least one downlink channel. The UE may transmit, to the BS, at least one uplink reference signal based on the at least one first uplink precoder for the at least one uplink channel.
