Title:
SIMULTANEOUS OR CONTEMPORANEOUS SPATIAL DOMAIN MULTIPLEXED PHYSICAL UPLINK SHARED CHANNEL TRANSMISSION USING A SINGLE DOWNLINK CONTROL INFORMATION AND TWO SOUNDING REFERENCE SIGNAL RESOURCE SETS
Document Type and Number:
WIPO Patent Application WO/2024/092561
Kind Code:
A1
Abstract:
A user equipment (UE) includes a transceiver associated with a first antenna panel and a second antenna panel of at least two antenna panels, and a processor configured to receive a single downlink control information (DCI) for simultaneous or contemporaneous codebook based physical uplink shared channel (PUSCH) transmission with spatial domain multiplexing (SDM). The processor is configured to receive a configuration of a first SRS-ResourceSet and a second SRS-ResourceSet of at least two sounding reference signal resource sets (SRS-ResourceSets). The first SRS-ResourceSet is mapped to the first antenna panel and the second SRS-ResourceSet is mapped to the second antenna panel. The processor is configured to transmit, simultaneously or contemporaneously, a first sounding reference signal (SRS) using the first SRS-ResourceSet and the first antenna panel, and a second SRS using the second SRS-ResourceSet and the second antenna panel for simultaneous or contemporaneous codebook based PUSCH transmission with SDM.
