Abstract

The emerging pinching antenna (PA) technology has high flexibility to reconfigure wireless channels and combat line-of-sight blockage, thus holding transformative potential for indoor immersive applications in 6G. This paper investigates Pinching-antenna systems (PASS) for indoor immersive communications. Our contributions are threefold: (1) we construct a 3D model to characterize the distribution of users, waveguides, and PAs in the PASS; (2) we develop a general theoretical model on downlink performance of PASS by capturing PA-user relationships and system parameters' impacts; and (3) we conduct comprehensive numerical results of the theoretical model and provide implementation guidelines for PASS deployments.
