Joint Sensing and Covert Communications in RIS-NOMA Systems
Jiayi Lei, Xidong Mu, Tiankui Zhang +2
A reconfigurable intelligent surface (RIS)-assisted non-orthogonal multiple access (NOMA) system is investigated, where the transmitter (Alice) is a dual functional radar communica…
Multi-Mode Pinching-Antenna Systems: Mode Selection or Mode Combining?
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +1
This letter investigates multi-mode pinching antenna systems (PASS), where signals of multiple orthogonal modes can be transmitted within a dielectric waveguide and radiated by pin…
Transmission Delay Minimization for NOMA-Based F-RANs
Yuan Ai, Xidong Mu, Pengbo Si +1
A novel non-orthogonal multiple access (NOMA) based low-delay service framework is proposed for fog radio access networks (F-RANs). Fog access points (FAPs) leverage NOMA for local…
Joint Transmit and Pinching Beamforming for Pinching Antenna Systems (PASS): Optimization-Based or Learning-Based?
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +1
A novel pinching antenna system (PASS)-enabled downlink multi-user multiple-input single-output (MISO) framework is proposed. PASS consists of multiple waveguides spanning over tho…
Multi-Mode Pinching Antenna Systems Enabled Multi-User Communications
Xiaoxia Xu, Xidong Mu, Yuanwei Liu +1
This paper proposes a novel multi-mode pinching-antenna systems (PASS) framework. Multiple data streams can be transmitted within a single waveguide through multiple guided modes,…
A Survey of Pinching-Antenna Systems (PASS)
Yuanwei Liu, Hao Jiang, Xu Gan +10
The pinching-antenna system (PASS), recently proposed as a flexible-antenna technology, has been regarded as a promising solution for several challenges in next-generation wireless…
