RIS-Assisted Downlink Pinching-Antenna Systems With NLOS Environments
This paper investigates a reconfigurable intelligent surface (RIS)-assisted downlink pinching-antenna system (PASS) in the presence of non-line-of-sight (NLOS) users caused by unavoidable obstacles. An RIS is deployed to extend the coverage of the physically constrained PASS by establishing virtual line-of-sight (LOS)...
