Abstract:
A method is provided for TCI switching related to CSI-RS measurement and reporting, spatial relation switch for SRS, PUSCH, and PUCCH. The PDSCH and PDCCH are received according to the QCLed aperiodic CSI-RS. When the AP CSI-RS is configured as the reference in the TCI of PDSCH, UE may apply the updated TCI for the PDSCH, after the corresponding aperiodic report has been received at the network. Spatial relation switch is based on the valid measurement report. The spatial relation switch delay of aperiodic SRS can be performed when UE has sent the corresponding measurement report to the network.
