Abstract
Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may receive a configuration (for example, via control signaling) of a set of reconfigurable intelligent surfaces (RISs). The UE may select a primary RIS for bidirectional wireless communication (for example, uplink and downlink) and one or more secondary RISs for unidirectional wireless communication (for example, downlink) based on the configuration. The UE may use the one or more secondary RISs to enable higher throughput and extended coverage in the wireless communication system, for example, for downlink. The UE may communicate with the base station using the primary RIS, or the secondary RIS, or both.
