A Simple Multiple-Access Design for Reconfigurable Intelligent
Surface-Aided Systems
Abstract
This paper focuses on multiple-access protocol design in a wireless
network assisted by multiple reconfigurable intelligent surfaces (RISs).
By extending the existing approaches in single-user or single-RIS cases,
we present two benchmark schemes for this multi-user multi-RIS scenario.
Inspecting their shortcomings, a simple but efficient method coined
opportunistic multi-user reflection (OMUR) is proposed.
