The TCI state switch delay for a reference signal (RS) on a component carrier (CC) in intra-band carrier aggregation (CA) is dependent on whether a TCI state indicated in the DCI is known based on a type of Quasi Co-Location (QCL) and whether a common TCI state ID is known on the CC. The delay is known for a delay of QCL-typeD RS on the CC or any other QCL-typeD RS in the CC set that contains the CC. The delay may be based on that of a single CC delay, with the slot where the new TCI state applies determined based on a carrier with a smallest subcarrier spacing (SCS) in the CC or the CC set.
