This study explores an incremental relaying strategy in downlink pairwise Non-Orthogonal
Multiple Access (NOMA), which involves multiple pairs of nodes near and far from the …

In this paper, we study the performance of the two-way relay network (TWRN) with NOMA-
based transmission, where the information is exchanged during three time slots. To provide …

In this paper, we exploit the spatial and transmission diversities in cooperative non-
orthogonal multiple access (C-NOMA) networks to improve the system sum-rate. To achieve …

Simultaneous wireless information and power transmission (SWIPT) allows the use of RF
signals for both information detection and energy harvesting. Integration of cooperation …

This paper studies the secure communications of a wireless-powered full-duplex
cooperative non-orthogonal multiple access (CoNOMA) system with a source node, a group …

This paper proposes transmission mode switching for the simultaneous wireless information
and power transfer enabled non-orthogonal multiple access (NOMA) systems with imperfect …

In this paper, we investigate the physical layer security for simultaneous transmission and
reflection (STAR) reconfigurable intelligent surface (RIS) aided systems. We consider a …

The rapid growth of connection density drives the next-generation wireless networks into
ultra-large-scale systems with massive access demand. Therefore, massive access is crucial …
