A user equipment (UE) includes a receiver that receives, from a base station (BS), one or more Transmission Configuration Indication (TCI) states for Physical Downlink Control Channel (PDCCH) reception via Radio Resource Control (RRC) signaling and a Medium Access Control Control Element (MAC CE) activation command for one of the TCI states via a Physical Downlink Shared Channel (PDSCH). The UE further includes a transmitter that transmits, to the BS, a Hybrid Automatic Repeat reQuest (HARQ) for the MAC CE activation command in a slot and a processor that activates the one of the TCI states k slots after the slot where the transmitter transmits the HARQ. A value of the k indicates a number of slots.
