Downlink control information for reconfigurable intelligent surface beam training

An apparatus for wireless communication at a base station, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit, to a reconfigurable intelligence surface (RIS) controller and one or more user equipments (UEs), downlink control information (DCI) associated with an RIS beam training, wherein the RIS controller and the one or more UEs are configured for the RIS beam training based at least in part on the DCI;
• and
• receive, from the one or more UEs, a report based at least in part on the DCI associated with the RIS beam training.
