Methods and apparatuses for beam management after channel setup. A method of operating a user equipment (UE) includes receiving at least one of synchronization signal/physical broadcast channel block (SSB) or channel state information reference signal (CSI-RS), measuring the at least one of the SSB or the CSI-RS, and determining downlink (DL) quasi-co-location (QCL) properties for DL communication based on the at least one of the SSB or the CSI-RS. The method further includes determining an uplink (UL) spatial domain filter for UL communication, receiving DL channels using the determined DL QCL properties until only one of only one joint TCI state or only one DL TCI state is configured, activated, or indicated to the UE, and transmitting UL channels using the determined UL spatial domain filter until only one of only one joint TCI state or only one UL TCI state is configured, activated, or indicated to the UE.
