Single layer uplink non-codebook based precoding optimization

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

• measuring a non-zero-power channel state information reference signal (NZP-CSI-RS) over one or more beams from a base station;
• determining a single beam for communication with the base station based on measurement of the NZP-CSI-RS;
• and
• transmitting a physical uplink shared channel (PUSCH) using the single beam and based on the UE determining the single beam for communication with the base station.

An apparatus for wireless communication at a base station, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• transmit a non-zero-power channel state information reference signal (NZP-CSI-RS) over one or more beams from a base station;
• skip transmission of a scheduling request indicator (SRI) to a user equipment (UE);
• and
• receive a physical uplink shared channel (PUSCH) on a single beam from the UE.
