Is the Envelope Beneficial to Non-Orthogonal Multiple Access?
Ziyi Xie, Wenqiang Yi, Xuanli Wu +2
Non-orthogonal multiple access (NOMA) is capable of serving different numbers of users in the same time-frequency resource element, and this feature can be leveraged to carry addit…
DRL Enabled Coverage and Capacity Optimization in STAR-RIS Assisted Networks
Xinyu Gao, Wenqiang Yi, Yuanwei Liu +2
Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) is a promising passive device that contributes to a full-space coverage via transmitting…
Ergodic Rate Analysis of STAR-RIS Aided NOMA Systems
Boqun Zhao, Chao Zhang, Wenqiang Yi +1
This letter analyzes the ergodic rates of a simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) aided non-orthogonal multiple access (NOMA) sys…
Coverage and Capacity Optimization in STAR-RISs Assisted Networks: A Machine Learning Approach
Xinyu Gao, Wenqiang Yi, Alexandros Agapitos +2
Coverage and capacity are the important metrics for performance evaluation in wireless networks, while the coverage and capacity have several conflicting relationships, e.g. high t…
Semi-Integrated-Sensing-and-Communication (Semi-ISaC): From OMA to NOMA
Chao Zhang, Wenqiang Yi, Yuanwei Liu +1
The new concept of semi-integrated-sensing-and-communication (Semi-ISaC) is proposed for next-generation cellular networks. Compared to the state-of-the-art, where the total bandwi…
Semi-Integrated-Sensing-and-Communication (Semi-ISaC) Networks Assisted by NOMA
Chao Zhang, Wenqiang Yi, Yuanwei Liu
This paper investigates non-orthogonal multiple access (NOMA) assisted integrated sensing and communication (ISaC) networks. Compared to the conventional ISaC networks, where the t…
