SUB-BAND SPECIFIC SOUNDING REFERENCE SIGNAL RESOURCE INDICATOR INDICATION FOR NON-CODEBOOK BASED FREQUENCY-SELECTIVE UPLINK PRECODING

Title:

SUB-BAND SPECIFIC SOUNDING REFERENCE SIGNAL RESOURCE INDICATOR INDICATION FOR NON-CODEBOOK BASED FREQUENCY-SELECTIVE UPLINK PRECODING

Document Type and Number:

WIPO Patent Application WO/2021/026679

Kind Code:

A1

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a sub-band specific sounding reference signal (SRS) resource indicator identifying subsets of SRS resources, of a set of SRS resources, associated with precoding a physical uplink shared channel (PUSCH) communication that is to be transmitted in a PUSCH resource. The user equipment may precode the PUSCH communication based at least in part on the sub-band specific SRS resource indicator. The user equipment may transmit the PUSCH communication after precoding the PUSCH communication based at least in part on the sub-band specific SRS resource indicator. Numerous other aspects are provided.
