Abstract
Methods, systems, and devices for wireless communications are described. In some systems, a base station may communicate with a user equipment (UE) via a reconfigurable intelligent surface (RIS) which is capable of adjusting a reflection characteristic to reflect incident signaling in different directions. The base station and the RIS may establish a beamformed connection and, in some scenarios, the base station and the RIS may experience a beam failure. In such scenarios, the base station, the UE, and the RIS may participate in a two-step beam training procedure to reduce an amount of possible beam pair hypotheses that the communicating devices test in order to re-establish communication between the base station and the UE via the RIS. The two-step beam training procedure may include a first procedure in which the RIS selects a suitable beam toward the base station and a second procedure that leverages the selected beam.
