Signaling schemes for reconfigurable intelligent surfaces in wireless communications

Abstract

Techniques are described for signaling in environments including one or more reconfigurable intelligent surfaces (RISs). An example wireless communication method includes transmitting, from a network device, a first signal to a subset of reflective elements of a surface comprising a plurality of reflective elements, the first signal being reflected off the surface in at least a first direction toward a wireless device. The method further includes receiving, from the wireless device, a second signal based on the first signal. For example, the first signal can include a reference signal, and the second signal can include a measurement of the reference signal. Based on the signaling, the subset, a different subset, or no subset of reflective elements can be selected for transmission.
