    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: 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.
