BEAM ACQUISITION FOR A RECONFIGURABLE INTELLIGENT SURFACE
This abstract first appeared for US patent application 20250007566 titled 'BEAM ACQUISITION FOR A RECONFIGURABLE INTELLIGENT SURFACE
Original Abstract Submitted
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.
