Title:
UPDATING SOUNDING REFERENCE SIGNAL SPATIAL RELATION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2021/146985
Kind Code:
A1
Abstract:
Apparatuses, methods, and systems are disclosed for updating SRS spatial relation information. One method includes transmitting first information indicating SRS spatial relation information for an SRS resource. The SRS spatial relation information includes: SRS spatial relation information identifiers; and an SRS spatial relation information reference signal corresponding to each SRS spatial relation information identifier. The method includes transmitting second information indicating an update to the SRS spatial relation information. The second information includes: a serving cell identifier; a bandwidth part identifier; one or more SRS resource identifiers, one or more SRS resource set identifiers, or a combination thereof; and one or more SRS spatial relation information identifiers. Each of the one or more SRS resource identifiers corresponds to each of the one or more SRS spatial relation information identifiers.
