1. A transmitting user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor communicatively coupled with the memory, the at least one processor configured to cause the transmitting UE to:
receive, from a network node, radio resource control (RRC) signaling that configures a data structure that indicates sidelink beam neighborhood information for each transmission configuration indication (TCI) state in a set of TCI states;
receive, from the network node, a sidelink grant that indicates one or more of a time resource or a frequency resource to use for a sidelink communication and indicates a set of sidelink beams associated with the sidelink communication in a TCI field that identifies a TCI state in the set of TCI states;
select, based at least in part on the set of sidelink beams indicated in the sidelink grant, a sidelink beam for the sidelink communication; and
transmit, via the selected sidelink beam, the sidelink communication to one or more receiving UEs using the one or more of the time resource or the frequency resource indicated in the sidelink grant.
