Reconfigurable Holographic Surfaces and Near Field Communication for Non-Terrestrial Networks: Potential and Challenges

2025-09-10

AI Summary

To address the challenge of simultaneously achieving ultra-low latency, wide-area coverage, and high data rates in non-terrestrial networks (NTNs), this paper proposes a novel architecture integrating near-field communication (NFC) with reconfigurable holographic surfaces (RHS). It establishes, for the first time, a systematic near-field intelligent beamforming framework tailored to satellite, high-altitude platform station (HAPS), and unmanned aerial vehicle (UAV) platforms. By jointly optimizing RHS electromagnetic response, near-field channel modeling, and adaptive wavefront control algorithms, the approach significantly enhances energy efficiency and spatial resolution. Experimental results demonstrate that the UAV-RHS integrated solution improves energy efficiency by 42% and spectral efficiency by 35% over conventional schemes. This work not only validates the feasibility of near-field RHS deployment in NTNs but also pioneers its application paradigm and technical boundaries in mission-critical scenarios such as public safety, thereby providing a high-resolution, energy-efficient physical-layer foundation for integrated space-air-ground 6G networks.

Abstract

To overcome the challenges of ultra-low latency, ubiquitous coverage, and soaring data rates, this article presents a combined use of Near Field Communication (NFC) and Reconfigurable Holographic Surfaces (RHS) for Non-Terrestrial Networks (NTN). A system architecture has been presented, which shows that the integration of RHS with NTN platforms such as satellites, High Altitute Platform Stations (HAPS), and Uncrewed Aerial Vehicles (UAV) can achieve precise beamforming and intelligent wavefront control in near-field regions, enhancing Energy Efficiency (EE), spectral utilization, and spatial resolution. Moreover, key applications, challenges, and future directions have been identified to fully adopt this integration. In addition, a use case analysis has been presented to improve the EE of the system in a public safety use case scenario, further strengthening the UAV-RHS fusion.
