SYSTEMS AND METHODS FOR SINGLE DOWNLINK CONTROL INFORMATION SIMULTANEOUS SPATIAL DIVISION MULTIPLEXING PHYSICAL UPLINK SHARED CHANNEL TRANSMISSION WITH SINGLE SOUNDING REFERENCE SIGNAL RESOURCE SET

Abstract

Systems and methods for single downlink control information (DCI) based simultaneous physical uplink shared channel (PUSCH) transmission with spatial division multiplexing (SDM) using a sounding reference signal (SRS) resource set are disclosed herein. The SRS resource set may be an exclusive (e.g., single) SRS resource set for either a non-codebook-based or a codebook-based simultaneous physical uplink shared channel (PUSCH) operation. In each case, a user equipment (UE) transmits the SRS resource(s) of the SRS resource set, receives a DCI from the network that schedules a first PUSCH transmission on a first UE panel and a simultaneous second PUSCH transmission on a second UE panel, and then transmits the (simultaneous) PUSCH transmissions as scheduled. Related network-side functionality is also discussed. In cases, SRS resources (and/or one or more SRS ports used by the SRS resource) are mapped to a particular UE panel. In other cases, SRS resources use both UE panels.
