1. A user equipment (UE), comprising:
a transceiver configured to:
receive configuration information for transmission configuration indication (TCI) states,
receive a beam indication including information indicating a number of TCI states and a number of corresponding TCI state application times, and
transmit a channel carrying an acknowledgment for the beam indication, wherein the TCI state application times are related to a time of the transmission of the channel; and
a processor operably coupled to the transceiver, the processor configured to determine, for one or more TCI states in the number of TCI states, at least one of downlink (DL) quasi-co-location (QCL) properties for DL communication and an uplink (UL) spatial domain filter for UL communication,
wherein the transceiver is further configured to at least one of:
receive, using the determined DL QCL properties, DL channels starting at the corresponding TCI state application times, and
transmit, using the determined UL spatial filter, UL channels starting at the corresponding TCI state application times.
