Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to a reconfigurable intelligent surface (RIS) controller associated with an RIS, a configuration for applying an RIS pattern. The network node may receive, from a network element, a measurement report indicating received observations of pilot signals reflected by the RIS in accordance with the RIS pattern. The network node may transmit, to the RIS controller and based at least in part on the measurement report, an indication of one or more of an updated codebook or a phase drift associated with a calibration of the RIS. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reconfigurable intelligent surface (RIS) may receive configuration information indicating a passive beamforming and information transfer (PBIT) scheme, the configuration information being based at least in part on at least one of energy consumption of the PBIT scheme or an error performance of the PBIT scheme. The RIS may communicate information available to the RIS to the network device based at least in part on the PBIT scheme. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reflecting device may generate a multi-peak reflection beam that spatially multiplexes a first reflected signal of a first signal and a second reflected signal of a second signal. The reflecting device may receive the first signal and the second signal. The reflecting device may reflect the first signal and the second signal to output a spatially multiplexed reflected signal using the multi-peak reflection beam. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A reconfigurable reflective surface (RIS) may receive control information from a network entity. The control information may be usable at the RIS for determination of a set of phase parameters. The RIS may determine whether distance information between the network entity and the RIS is available. The RIS may determine the set of phase parameters in accordance with the control information. The set of phase parameters may be usable by the RIS for reflecting communications from the network entity to a user equipment (UE) in accordance with a focusing distance that may be based on the determined availability of the distance information. The RIS may apply the set of phase parameters to reflect a signal from the network entity to the UE.
