A Unified Approach for Pinching-Antenna-Assisted Non-Orthogonal Multiple Access With Integrated Sensing and Communication

The novel flexible-antenna technology, referred to as pinching-antennas, has recently attracted significant academic interest. By embedding separate dielectric materials, these antennas can be activated at arbitrary points along waveguides, facilitating the flexible configuration of large-scale path loss. This paper co...

Power Minimization for Pinching-Antenna Systems: Flexible Hybrid NOMA Perspective

Pinching-antenna systems have emerged as a novel promising technology for sixth-generation networks, capable of enhancing spectral efficiency by dynamically creating radiation points and line-of-sight links along a dielectric waveguide. However, the power consumption of such reconfigurable systems remains a critical ch...

Outage-Constrained Environment Division Multiple Access (EDMA) for Pinching-Antenna Systems

A multi-user PA-enabled EDMA framework that accounts for probabilistic line-of-sight blockages, random non-LoS (NLoS) scattering, and practical inwaveguide attenuation is investigated, which yields significant performance gains over both PA-enabled and conventional time division multiple access designs.

Rate Maximization and Outage Analysis for BackCom-Assisted Uplink Pinching-Antenna Systems in IoT

In this paper, we consider a backscatter communication (BackCom)-assisted uplink pinching-antenna system in Internet of Things (IoT), where a non-energy-constrained IoT device provides radio frequency signals to support multiple energy-constrained IoT devices, with multiple pinching antennas deployed on a waveguide. We...
