Method for control signaling for multi-beam pusch repetition transmission

A method of operating a base station (BS), the method comprising:

• configuring a plurality of sounding reference signal (SRS) resources;
• transmitting downlink control information (DCI) to a user equipment (UE) to schedule transmission of a plurality of physical uplink shared channel (PUSCH) repetitions to at least two transmission-reception points (TRPs), the DCI to include:
• a first SRS resource indicator (SRI) to indicate a first number of SRS ports for a first SRS resource of the plurality of SRS resources, the first SRS resource associated with a first PUSCH repetition of the plurality of PUSCH repetitions;
• and a second SRI to indicate a second number of SRS ports for a second SRS resource of the plurality of SRS resources, the second SRS resource associated with a second PUSCH repetition of the plurality of PUSCH repetitions, wherein the first number is equal to the second number;
• and
• receiving the first or second PUSCH repetition from the UE.

One or more non-transitory, computer-readable media having instructions that, when executed, cause a user equipment (UE) to:

• receive a configuration of a plurality of sounding reference signal (SRS) resources;
• receive downlink control information (DCI) that schedules transmission of a plurality of physical uplink shared channel (PUSCH) repetitions to at least two transmission-reception points (TRPs), the DCI to include:
• a first SRS resource indicator (SRI) to indicate a first number of SRS ports for a first SRS resource of the plurality of SRS resources, the first SRS resource associated with a first PUSCH repetition of the plurality of PUSCH repetitions;
• and a second SRI to indicate a second number of SRS ports for a second SRS resource of the plurality of SRS resources, the second SRS resource associated with a second PUSCH repetition of the plurality of PUSCH repetitions, wherein the first number is equal to the second number;
• and
• select a first precoder for the first PUSCH repetition and a second precoder for the second PUSCH repetition based on the DCI.
