Stacked Intelligent Metasurface Assisted Multiuser Communications: From a Rate Fairness Perspective
Junjie Fang, Chao Zhang, Jiancheng An +4
Stacked intelligent metasurface (SIM) extends the concept of single-layer reconfigurable holographic surfaces (RHS) by incorporating a multi-layered structure, thereby providing en…
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…
Semi-Grant-Free NOMA: Ergodic Rates Analysis with Random Deployed Users
Chao Zhang, Yuanwei Liu, Wenqiang Yi +2
Semi-grant-free (Semi-GF) non-orthogonal multiple access (NOMA) enables grant-free (GF) and grant-based (GB) users to share the same resource blocks, thereby balancing the connecti…
Reconfigurable Intelligent Surfaces Aided Multi-Cell NOMA Networks: A Stochastic Geometry Model
Chao Zhang, Wenqiang Yi, Yuanwei Liu
By activating blocked users and altering successive interference cancellation (SIC) sequences, reconfigurable intelligent surfaces (RISs) become promising for enhancing non-orthogo…
