Document Type and Number:
WIPO Patent Application WO/2024/031635
Kind Code:
A1
Abstract:
A coordinated multi-point transmission method and apparatus and a storage medium. The coordinated multi-point transmission method is applied to a terminal, and comprises: acquiring coordinated multi-point transmission configuration information configured by a network device, the coordinated multi-point transmission configuration information being used for configuring a plurality of TRPs or a plurality of TRP groups, each TRP group comprising at least one TRP, and the plurality of TRPs or the plurality of TRP groups perform coherent coordinated transmission; on the basis of the coordinated multi-point transmission configuration information, selecting, among the plurality of TRPs that perform coherent transmission, all or some TRPs for coherent transmission, or selecting, among the plurality of TRP groups that perform coherent transmission, all or some TRP groups for coherent transmission; and sending indication information to the network device, the indication information being used for indicating the TRPs selected by the terminal among the plurality of TRPs and used for coherent transmission, or used for indicating the TRP groups selected by the terminal among the plurality of TRP groups and used for transmission. According to the present application, indication feedback overhead of terminals can be reduced.
