In this letter, the application of non-orthogonal multiple access (NOMA) to Terahertz (THz) transmission is proposed in order mitigate harmful effect beam alignment errors. particular, two types cognitive radio inspired NOMA (CR-NOMA) schemes are developed realize different tradeoffs between system performance and user fairness. Both analytical simulation results presented demonstrate superior ...

Non-orthogonal multiple access (NOMA) is an emerging technique promising to accommodate the increasing data rate requirements of next generation networks. In power-domain (PD) NOMA, this challenge addressed by allocating two or more users on each orthogonal resource block while assigning significantly different power levels all users. Recently, interesting alternative conventional PD-NOMA has b...

With the increasing number of Internet Things (IoT), Industry 4.0 (I4.0), and mobile devices, it can be expected that base stations will have to serve more clients with a limited antennas. For their broadcast channels, nonorthogonal multiple access (NOMA) blind interference alignment (BIA) are two efficient commonly adopted transmission schemes. This paper conducts comparison study on these tec...

A novel framework is proposed to integrate communication, control, and computing (3C) into fifth generation beyond (5GB) wireless networks for satisfying the ultra-reliable low-latency connectivity requirements of remote e-health systems. Non-orthogonal multiple access (NOMA)-enabled 5GB network architecture envisioned, while benefits bringing it systems are demonstrated. First, application NOM...

This article focuses on the development of integrated sensing and communications (ISAC) from a multiple access (MA) perspective, where idea non-orthogonal (NOMA) is exploited for harmoniously accommodating communication functionalities. We first reveal that developing trend ISAC \emph{orthogonality} to \emph{non-orthogonality}, introduce fundamental models downlink uplink while identifying desi...

This paper proposes an uplink non-orthogonal multiple access (NOMA) system with device-to-device (D2D) communication, enabling NOMA users to communicate other users/devices using D2D communication improve the capacity. In NOMA-D2D system, two cellular communicated BS NOMA, and simultaneously downlink NOMA. Closed-form solutions for ergodic sum capacity of proposed are derived analytically. The ...

In uplink block-fading multiple access channel (BFMAC), the advantage of multiuser diversity (MUD) can be taken to achieve higher system throughput. In this letter, with rate constraints for all users and only channel state information available at the receiver assumed, we demonstrate that nonorthogonal multiple access (NOMA) outperforms the counterpart of orthogonal multiple access (OMA) via e...

In this paper, a novel hybrid non-orthogonal multiple access (NOMA) system that combines the cooperative NOMA (C-NOMA), original NOMA, and orthogonal (OMA) is investigated. The probability-based user management algorithm (PUMA) proposed for considered with regard to fulfilling requirements of 5G beyond communications, which joint transmission mode selection pairing scheme. effective region stoc...
