1. A method performed by a base station, the method comprising:
transmitting higher layer parameters to a user equipment (UE) to configure two or more sounding reference signal (SRS) resource sets for a non-codebook based physical uplink share channel (PUSCH) transmission, wherein each SRS resource set is associated with a non-zero power (NZP) channel state information reference signal (CSI-RS) resource, a first SRS resource set of the two or more SRS resource sets is associated with a first uplink (UL) transmit (TX) beam for the UE, a second SRS resource set of the two or more SRS resource sets is associated with a second UL TX beam for the UE, and the first UL TX beam and the second UL TX beam are configured for simultaneous transmission associated with the first SRS resource set and the second SRS resource set;
configuring quasi-colocation (QCL) information that indicates a receiver beam to receive each NZP CSI-RS resource and only one SRS port can be configured for the each SRS resource set;
transmitting the QCL information; and
transmitting a downlink control information (DCI) with two or more sounding reference signal SRS resource indicator (SRI) fields to schedule a non-codebook based PUSCH transmission, wherein each SRI field of the two or more SRI fields is associated with one or more SRS resources within the first or the second SRS resource set.
