Abstract:
A method of activating a secondary cell (SCell) can include receiving on a primary cell (PCell) at a user equipment (UE) a first medium access control (MAC) control element (CE) for activating the SCell, receiving on the PCell a second MAC CE for indicating a first transmission configuration indication (TCI) state for receiving one of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH) of the SCell, starting to perform a time-frequency tracking process in the SCell based on a synchronization signal block (SSB) indicated in the first TCI state without waiting for an arrival of a third MAC CE on the PCell for activating a semi-persistent (SP) channel state information reference signal (CSI-RS) resource set of the SCell, and performing a CSI reporting process based on the SP CSI-RS resource set activated by the third MAC CE on the SCell.
