Abstract
Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.
