The method includes receiving network information and obtaining a CSI report based on the network information. The CSI report includes CSI measurement results in a coherent joint transmission hypothesis for one or more stations.

A monitoring method includes: not expecting to monitor a physical downlink control channel (PDCCH) in a target type common search space (CSS) set or not expecting to monitor a PDCCH in a Type1-PDCCH CSS set, if a quasi-co-location type D (QCL-TypeD) property of a first demodulation reference signal (DM-RS) for monitoring the PDCCH in the Type1-PDCCH CSS set is different from a QCL-TypeD property of a second DM-RS for monitoring the PDCCH in the target type CSS set, and if the PDCCH in the Type1-PDCCH CSS set or a physical downlink shared channel (PDSCH) associated with the PDCCH in the Type1-PDCCH CSS set overlaps in at least one symbol with the PDCCH in the target type CSS set or with a PDSCH associated with the PDCCH in the target type CSS set, where the target type is Type0B-PDCCH, and/or Type2A-PDCCH, and/or Type1A-PDCCH.

Embodiments of the present disclosure provides a feedback method and apparatus, SCI sent by a second UE to a first UE is used to indicate N time-frequency resources, the second UE sends a PSSCH to the first UE on each of the N time-frequency resources, the N PSSCHs correspond to the same TB, the first UE determines L time-frequency resources according to the N time-frequency resources indicated by the first SCI, and time domains of PSFCH resources respectively corresponding to the L time-frequency resources are the same. Afterwards, the first UE feeds back to the second UE according to the PSFCH resource and received PSSCH.

A method for processing channel state information (CSI) for a non-serving cell is disclosed. The method includes receiving downlink control information (DCI) for triggering an aperiodic CSI report; determining whether the aperiodic CSI report is an aperiodic CSI report for the non-serving cell; and determining that a CSI computation delay requirement for the aperiodic CSI report corresponds to a predefined first CSI computation delay requirement, based on a determination that the aperiodic CSI report belongs to the aperiodic CSI report for the non-serving cell, where the first CSI computation delay requirement is greater than or equal to a second CSI computation delay requirement corresponding to a serving cell.
