Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a network entity to determine a beam focusing distance for a reconfigurable intelligent surface (RIS) for a user equipment (UE) located in the near field region of the RIS. The beam focusing distance may be determined using reference signals for different test beam focusing distances within the near field region of the RIS. The test beams may have a same angular direction from the RIS to the UE. The test beams may have a beam focusing distance selected from a set of beam focusing distances within the near field region of the RIS.

Abstract: Methods, systems, and devices for wireless communications are described. A controller of a reconfigurable intelligent surface (RIS) may transmit a capability message indicating a capability of one or more configurable elements of the RIS to direct incoming signals in one or more directions for one or more frequency bands. For example, the configurable elements may have an ability to act as transparent to the signal, to direct the signal in an interference safe direction or frequency, and/or to diffuse the signal across multiple directions or frequencies. The controller of the RIS may control the one or more configurable elements in accordance with the capability message and an activity status of the RIS to direct a signal to at least one direction. In some cases, a network entity may transmit an indication of the at least one direction to the RIS controller.

Abstract: Certain aspects of the present disclosure provide techniques for a method for wireless communication by a first wireless entity, comprising: receiving signaling from a second network entity to configure reconfigurable intelligent surface (RIS) elements based on a direction of a target incident signal and a direction of a target reflected signal, and configuring the RIS elements based on the direction of the target incident signal and the direction of the target reflected signal and to randomize reflections, based on the signaling.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a network entity to indicate a desired beamforming coverage scheme to a controller of a reconfigurable intelligent surface (RIS). The RIS controller may identify one or more realizable multi-lobe beamforming patterns in accordance with the desired beamforming coverage scheme, and may transmit multi-lobe beam information indicating the one or more realizable multi-lobe beamforming patterns to the network entity. In some cases, the RIS may indicate single-lobe beam information to the network entity, and the network entity may transmit one or more vectors to support generating the multi-lobe beam information. In some examples, based on the multi-lobe beam information, the network entity may indicate a multi-lobe beamforming pattern that the RIS is to use for relaying a multi-lobe reflect beam or a multi-lobe incident beam.
