Special Issue Information

Dear colleagues,

The standardization of fifth-generation (5G) mobile communication network technologies has been completed, and 5G is expected to be deployed around most of the world by the end of 2020. To ensure continuity and competitiveness in wireless communication systems, efforts from industry and academia have started to conceptualize the next generation of wireless communication systems, also known as sixth generation (6G). The sixth generation aims to provide revolutionary communication services and applications to meet the future demands in the 2030s while promoting sustainable development to the environment. The aim of this Special Issue is to highlight the most promising lines of research, which share common directions toward sustainable 5G and 6G communication systems.

This Special Issue encourages researchers to present original and recent developments in fundamental theory, performance limits, design, management issues, and challenges and promising solutions for sustainable 5G and 6G communication systems. Topics of interest include but are not limited to the following areas:

  • Energy-aware design of 5G/6G transmissions and communication systems;
  • Wireless energy transfers and energy harvesting for sustainable 5G/6G systems;
  • Potential 5G/6G applications toward sustainable development growth;
  • Transdisciplinary approaches toward sustainable 5G/6G developments and implementations;
  • Application of information theory to the 5G/6G communication systems;
  • Big data and edge AI technology as enablers for 5G/6G communication systems;
  • Novel interference solutions and resource controls for 5G/6G communication systems;
  • Cell-free massive MIMO for 5G/6G communication systems;
  • Propagation modeling on millimeter waves and terahertz spectrum;
  • High intelligence versus privacy and complexity;
  • Three-dimensional integrated communications;
  • Ultra-reliable low-latency communications;
  • Security and reliability issues with 6G/IoT.

We hope this Special Issue will achieve a precise, concrete, and concise conclusion that contributes significantly to opening new horizons for future research directions.

Massive multiple-input multiple-output (MIMO) is a backbone technology in the fifth-generation (5G) and beyond 5G (B5G) networks. It enhances performance gain, energy efficiency, and spectral efficiency. Unfortunately, a massive number of antennas need sophisticated processing to detect the transmitted signal. Although a detector based on the maximum likelihood (ML) is optimal, it incurs a high computational complexity, and hence, it is not hardware-friendly. In addition, the conventional linear detectors, such as the minimum mean square error (MMSE), include a matrix inversion, which causes a high computational complexity. As an alternative solution, approximate message passing (AMP) algorithm is proposed for data detection in massive MIMO uplink (UL) detectors. Although the AMP algorithm is converging extremely fast, the convergence is not guaranteed. A good initialization influences the convergence rate and affects the performance substantially together and the complexity. In this paper, we exploit several free-matrix-inversion methods, namely, the successive over-relaxation (SOR), the Gauss–Seidel (GS), and the Jacobi (JA), to initialize the AMP-based massive MIMO UL detector. In other words, hybrid detectors are proposed based on AMP, JA, SOR, and GS with an efficient initialization. Numerical results show that proposed detectors achieve a significant performance enhancement and a large reduction in the computational complexity. Full article
