High-speed train (HST) communications face severe challenges in providing reliable data services to users due to the rapid channel variation and beam misalignment caused by high mobility. To address these issues, we propose a rotatable antenna (RA)-enabled HST relaying system, where both the base station (BS) and the t...

Space-air-ground integrated networks (SAGINs) are expected to support ubiquitous three-dimensional (3D) communication and sensing services in future sixth-generation (6G) wireless networks. However, heterogeneous mobility and service requirements across the space, air, and ground segments challenge fixed-boresight or f...

Integrated sensing, communication, and computing (ISCC) is a promising paradigm for future sixth-generation (6G) networks. However, existing ISCC systems rely on fixed-antenna architectures, which limit spatial degrees-of-freedom (DoFs) and adaptability in dynamic wireless environments. In this paper, we investigate a...

This paper investigates a novel self-sustainable intelligent reflecting surface (IRS)-enhanced multi-input multi-output simultaneous wireless information and power transfer (SWIPT) system under imperfect channel state information. Equipped with an energy harvesting module, the IRS harvests energy from received signals...
