STAR-RIS Aided NOMA in Multi-Cell Networks: A General Analytical Framework with Gamma Distributed Channel Modeling
Ziyi Xie, Wenqiang Yi, Xuanli Wu +2
The simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) is capable of providing full-space coverage of smart radio environments. This work inve…
STAR-IOS Aided NOMA Networks: Channel Model Approximation and Performance Analysis
Chao Zhang, Wenqiang Yi, Yuanwei Liu +2
Simultaneous transmitting and reflecting intelligent omini-surfaces (STAR-IOSs) are able to achieve full coverage "smart radio environments". By splitting the energy or altering th…
A Power-Pool-Based Power Control in Semi-Grant-Free NOMA Transmission
Muhammad Fayaz, Wenqiang Yi, Yuanwei Liu +1
In this paper, we generate a transmit power pool (PP) for Internet of things (IoT) networks with semi-grant-free non-orthogonal multiple access (SGF-NOMA) via multi-agent deep rein…
Modeling and Coverage Analysis for RIS-aided NOMA Transmissions in Heterogeneous Networks
Ziyi Xie, Wenqiang Yi, Xuanli Wu +2
Reconfigurable intelligent surface (RIS) has been regarded as a promising tool to strengthen the quality of signal transmissions in non-orthogonal multiple access (NOMA) networks.…
Multi-cell NOMA: Coherent Reconfigurable Intelligent Surfaces Model With Stochastic Geometry
Chao Zhang, Wenqiang Yi, Yuanwei Liu +1
Reconfigurable intelligent surfaces (RISs) become promising for enhancing non-orthogonal multiple access (NOMA) systems, i.e., enhancing the channel quality and altering the SIC or…
Developing NOMA to Next Generation Multiple Access (NGMA): Future Vision and Research Opportunities
Yuanwei Liu, Wenqiang Yi, Zhiguo Ding +3
As a prominent member of the next generation multiple access (NGMA) family, non-orthogonal multiple access (NOMA) has been recognized as a promising multiple access candidate for t…
