Abstract
Uplink channel measurement method and apparatus for multi-TRP scene, storage medium, terminal, and base station are provided. The method includes: receiving SRS scheduling information indicating an SRS resource set triggered by current uplink channel measurement; receiving an CSI-RS resource associated with the SRS resource set, and performing time-frequency offset compensation and channel estimation to obtain a complete downlink channel matrix, wherein the CSI-RS resource is used to measure downlink channel state of a plurality of TRPs, and the complete downlink channel matrix includes downlink channel matrixes of the TRPs; acquiring a complete uplink channel matrix by transforming the complete downlink channel matrix, wherein the complete uplink channel matrix includes uplink channel matrixes of the TRPs; determining and transmitting preset number of precoded SRS resources based on the complete uplink channel matrix, wherein the preset number is determined based on a number of SRS resources included in the SRS resource set.
