A first UE may receive, from a base station or a second UE, one or more first TCI states via RRC signaling. The first UE may receive, from the base station or the second UE, one or more MAC-CEs. Each of the one or more MAC-CEs may include at least one indication of one or more second TCI states. The one or more second TCI states may be a subset of the one or more first TCI states. The first UE may transmit to the second UE, or receive from the second UE, a sidelink message via a sidelink channel based on a third TCI state. The third TCI state may be from the one or more second TCI states.
