Title:
SOUNDING REFERENCE SIGNAL CONFIGURATIONS TO SUPPORT UPLINK TRANSMISSIONS WITH CYCLIC DELAY DIVERSITY
Document Type and Number:
WIPO Patent Application WO/2020/061467
Kind Code:
A3
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a sounding reference signal (SRS) resource set to be used to signal a virtual port used for a physical uplink shared channel (PUSCH) communication, wherein the virtual port is a combination of at least two non-coherent or partially-coherent antenna ports of the UE using precoding and cyclic delay diversity; and transmit an SRS for the at least two non-coherent or partially-coherent antenna ports using one or more resources of the SRS resource set. Numerous other aspects are provided.
