Abstract: A communication system may include a wireless base station (BS), a user equipment (UE) device, and a hybrid reconfigurable intelligent surface (HRIS) co-located with the UE device. The HRIS may be used to offload beam management procedures to the BS. Adjustable devices on the HRIS may configure antenna elements of the HRIS to reflect incident signals from the BS and may configure antenna elements of the HRIS to receive the incident signals using a receiver according to a time domain multiplexing scheme, a spatial domain multiplexing scheme, and/or a power domain multiplexing scheme. The UE device may control the HRIS to switch between the schemes and to adjust a proportion of the incident signal that is reflected or received over time. The HRIS may be used in facilitating a beam acquisition and tracking procedure for the UE device and the BS, thereby minimizing resource consumption on the UE device.
