US 12,732,260 B2 · Wireless communication using hybrid reconfigurable intelligent surfaces

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.

Dependent claims

A reconfigurable intelligent surface (RIS) co-located with a user equipment (UE) device, the RIS comprising:

an array of antenna elements configured to transmit signals for the UE device;
adjustable devices coupled to the antenna elements;
a receiver, wherein the adjustable devices configure a first set of antenna elements in the array to pass an incident signal to the receiver and configure a second set of antenna elements in the array to reflect the incident signal;
and
one or more processors configured to adjust impedances of the adjustable devices.
