    Abstract: Techniques discussed herein can facilitate the use of reference signals in active TCI switching. One example aspect is a user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: receive a physical downlink shared channel (PDSCH) message that includes an activation command indicating a target transmission configuration indicator (TCI) state; decode the activation command within a decoding period, where the decoding period is a time period allocated for the UE to decode the activation command; receive a TCI resource where the TCI resource is a reference signal; perform time and frequency tracking associated with the target TCI state according the TCI resource; and switch to the target TCI state after performing time and frequency tracking.
