Abstract: An apparatus and system for a unified transmission configuration indicator (TCI) state switch requirement are described. Both radio resource management and TCI state switch delay requirements are described. The UL TCI state switch delay requirement may depend on whether a downlink (DL) reference signal (RS) associated with the UL TCI state satisfies known conditions, as well as whether a joint or separate TCI mode is being used. In the separate TCI mode. the delay requirement may include timing between a DL data transmission and acknowledgement, and also include a time for receive beam refinement in frequency range2. In the joint TCI mode. the UL and DL TCI state switch delay requirement—due may be the same or may be the same as the separate TCI mode.
