Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling configuring a first active transmission configuration indication (TCI) state for an initial control resource set and a second active TCI state for a second control resource set. The UE may monitor the initial control resource set using a first beam corresponding to the first active TCI state, the second control resource set using a second beam corresponding to the second active TCI state, and a shared data channel using one of the two beams. The UE may perform a random access channel procedure to select a third beam and update a quasi co-location assumption for the initial control resource set to correspond to the third beam. The UE may apply a selection rule for selecting between the second beam and the third beam and monitor the shared data channel using the selected beam.
