Abstract
Methods, systems, and devices for wireless communications are described. The described techniques provide for beam training a reconfigurable intelligent surface (RIS) for sidelink communications between UEs. A base station may transmit an indication of a resource pool to a receiving UE and a transmitting UE for beam training a RIS. The transmitting UE may identify a resource pattern for training the RIS using the indicated resource pool where the resource pattern is associated with a pattern of beams at the RIS. The transmitting UE may transmit a sidelink reference signal using the identified resource. The receiving UE may receive the reference signal via the RIS according the pattern of beams and transmit a beam report to the transmitting UE. Beam training may be based on a capability of the RIS to use either a different beamformer or a different RIS configuration on different subchannels of the same resource pool.
