Abstract:
A configuration to reduce a timeline for non-codebook based uplink precoding procedures. The apparatus measures an NZP-CSI-RS over one or more beams from a base station. The apparatus determines a single beam for communication with the base station based on measurement of the NZP-CSI-RS. The apparatus transmits a PUSCH using the single beam and based on determining the single beam for communication with the base station. The apparatus may receive a configuration from the base station to perform a SRS-less non-codebook based uplink precoding procedure. The UE may transmit the PUSCH using the single beam and without transmitting an SRS further based on the configuration from the base station. The apparatus may skip transmission of an SRS between measurement of the NZP-CSI-RS and transmission of the PUSCH.
