Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) with the capability to support a single active TCI state may receive configuration signaling which configures the UE with an active transmission configuration indication (TCI) state corresponding to a first beam for a control resource set and a shared data channel. The UE may perform a random access channel procedure to select a second beam from a set of different beams. The UE may update a quasi co-location (QCL) assumption for the control resource set to correspond to the second beam and deactivate the active TCI state based on updating the QCL assumption. The UE may then monitor the control resource set, the shared data channel, or both, using the second beam. The UE may deactivate the TCI state and use the indicated downlink beam so that the UE does not exceed its capability.
