Non-Terrestrial Networks enable wide-area connectivity in remote and underserved regions. However, the rapid growth of Internet of Things applications poses challenges in achieving high transmission capacity while maintaining fairness under heterogeneous channel conditions. Conventional sum-rate maximization prioritize...
In this paper, we study two schemes for the fair resource allocation in wireless powered communication networks (WPCNs): a non-orthogonal multiple access (NOMA) scheme, and a proportional fair (PF) scheduling scheme. The considered WPCN consists of a base station (BS) that broadcast radio frequency (RF) energy over the...
Coordinated orthogonal frequency division multiple access (C-OFDMA) and centralized Wi-Fi access network (C-WAN) are two promising techniques for next generation Wi-Fi networks. While C-WAN enables centralized multi-access point coordination and C-OFDMA improves spectrum reuse through resource unit (RU) sharing, fairne...
This study investigates an Aerial-Ground Integrated Heterogeneous network (AGIHN) architecture that combines terrestrial macro base stations and unmanned aerial vehicles (UAVs) serving as aerial base stations to enhance uplink access for macrocell users. To address the complex uplink resource allocation challenge for m...
This paper proposes a hybrid non-orthogonal multiple access (NOMA) framework for tacking the energy efficiency optimization problem of serving additional users with pre-configured beams in the near-field downlink of ultra-massive multiple-input multiple-output (MIMO) systems. This proposed approach formulates a resourc...
Simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) is crucial to achieve full-space coverage in next-generation wireless networks. However, optimizing resource allocation in STAR-RIS-assisted systems to balance the system sum rate with user fairness, especially in the presence of imp...
