Models, Methods, and Solutions for Multicasting in 5G/6G mmWave and Sub-THz Systems

“…Sidelink technology, which is an extension of the LTE system allowing for D2D communications without using BS as an intermediate point, can be utilized to bridge over the multicast difficulties [198], [199].

“…The problem of relay selection in D2D-aided multicasting has been the focus of several recent studies. For instance, in [125], a method for relay selection that improves energy efficiency and power allocation for multi-source networkcoded cooperative D2D communication is proposed for LTE systems, readily adaptable for mmWave networks. Similarly, in [126], a low-complexity, location-based hybrid multiple access scheme and relay selection algorithm are presented for V2X communications when no sidelink CSI is available.…”

Resource Allocation Based on SFLA Algorithm for D2D Multicast Communications

“…One of the basic 5G technologies is D2D communication network, which is described as a collection of devices that can communicate with each other wirelessly without the need for an infrastructure or a central authority [3]. The rapid increase in CUs, combined with the high demand for improving quality of service (QoS), has resulted in a decrease in spectral resources, which is one of several main factors restricting the development of modern communication networks [4,5] with the foreseeable explosion in the number of wireless devices, and the continuing development of multimedia services [6]. Multiplayer gaming and video streaming are considered as group communication applications, require firstly a high data rate and secondly low latency.…”

Ultrahigh‐Dimensional Model and Optimization Algorithm for Resource Allocation in Large‐Scale Intelligent D2D Communication System

“…As a result, the deviceto-device (D2D) communication technology is developed and plays an increasingly important role in the modern 5G cellular networks [1,2]. However, due to the fast growing cellular users and high requirement for quality of service (QoS), the lack of spectrum resource becomes one of the main reasons which severely restricts the development of modern communication network [3,4].…”
