Title:
SIGNALING SCHEMES FOR RECONFIGURABLE INTELLIGENT SURFACES IN WIRELESS COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2023/130286
Kind Code:
A1
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.
