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…
Knowledge-aided Federated Learning for Energy-limited Wireless Networks
Zhixiong Chen, Wenqiang Yi, Yuanwei Liu +1
The conventional model aggregation-based federated learning (FL) approach requires all local models to have the same architecture, which fails to support practical scenarios with h…
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…
Dynamic Task Software Caching-assisted Computation Offloading for Multi-Access Edge Computing
Zhixiong Chen, Wenqiang Yi, Atm S. Alam +1
In multi-access edge computing (MEC), most existing task software caching works focus on statically caching data at the network edge, which may hardly preserve high reusability due…
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…
Intelligent Trajectory Design for RIS-NOMA aided Multi-robot Communications
Xinyu Gao, Xidong Mu, Wenqiang Yi +1
A novel reconfigurable intelligent surface-aided multi-robot network is proposed, where multiple mobile robots are served by an access point (AP) through non-orthogonal multiple ac…
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…
Efficient Wireless Federated Learning with Partial Model Aggregation
Zhixiong Chen, Wenqiang Yi, Arumugam Nallanathan +1
The data heterogeneity across devices and the limited communication resources, e.g., bandwidth and energy, are two of the main bottlenecks for wireless federated learning (FL). To…
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…
A Reliable Reinforcement Learning for Resource Allocation in Uplink NOMA-URLLC Networks
Waleed Ahsan, Wenqiang Yi, Yuanwei Liu +1
In this paper, we propose a deep state-action-reward-state-action (SARSA) learning approach for optimising the uplink resource allocation in non-orthogonal multiple access (NOM…
