The described techniques relate to improved methods, systems, devices, and apparatuses that support configurations for sidelink beam management. In some cases, a base station may determine sidelink beams for beam sweeping and instruct a user equipment (UE) which sidelink beams to use. The base station may determine the sidelink beams for beam sweeping based on a report sent from the UE. In other cases, the UE may determine transmission sidelink beams for beam sweeping based on the UE capabilities beam input from the receiving UE, or the base station determining which beams to use and allocating resources for the beam sweeping. Additionally or alternatively, the base station may determine a portion of the sidelink beams for beam sweeping and the UE may determine a portion of the sidelink beams to use for beam sweeping in addition to the beams indicated by the base station.
