Age of Information: Can CR-NOMA Help?
Zhiguo Ding, Robert Schober, H. V. Poor
The aim of this paper is to exploit cognitive-ratio inspired NOMA (CR-NOMA) transmission to reduce the age of information in wireless networks. In particular, two CR-NOMA transmiss…
Joint Beam Management and Power Allocation in THz-NOMA Networks
Zhiguo Ding, H. Vincent Poor
This paper investigates how to apply non-orthogonal multiple access (NOMA) as an add-on in terahertz (THz) networks. In particular, prior to the implementation of NOMA, it is assum…
New Antenna Selection Schemes for Full-Duplex Cooperative MIMO-NOMA Systems
Zahra Mobini, Mohammadali Mohammadi, Theodoros A. Tsiftsis +2
In this paper, we address the antenna selection (AS) problem in full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay bridges t…
NOMA Beamforming in SDMA Networks: Riding on Existing Beams or Forming New Ones?
Zhiguo Ding
In this letter, the design of non-orthogonal multiple access (NOMA) beamforming is investigated in a spatial division multiple access (SDMA) legacy system. In particular, two popul…
Uplink NOMA For STAR-RIS Networks
Jiakuo Zuo, Yuanwei Liu, Zhiguo Ding +1
A simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) enhanced uplink non-orthogonal multiple access (NOMA) communication system is proposed.…
Deep Reinforcement Learning Based Multidimensional Resource Management for Energy Harvesting Cognitive NOMA Communications
Zhaoyuan Shi, Xianzhong Xie, Huabing Lu +3
The combination of energy harvesting (EH), cognitive radio (CR), and non-orthogonal multiple access (NOMA) is a promising solution to improve energy efficiency and spectral efficie…
