摘要:

大规模接入,也称为大规模连接或大规模机器类型通信(mMTC),是第五代(5G)及超5G(B5 G)无线网络的主要用例之一。大规模接入的典型应用是蜂窝物联网(IoT)。与传统的人型通信不同,大规模接入旨在为大量物联网设备实现高效可靠的通信。因此,大规模接入的主要特征包括低功率、大规模连接和广覆盖,这需要新的概念、理论和范例来设计下一代蜂窝网络。本文对B5G无线网络大规模接入设计的各个方面进行了全面的综述。具体而言,我们提供了一个详细的审查,从理论,协议,技术,覆盖范围,能源和安全的角度大规模访问。此外,一些未来的研究方向和挑战。

英文摘要:

Massive access, also known as massive connectivity or massive machine-type communication (mMTC), is one of the main use cases of the fifth-generation (5G) and beyond 5G (B5G) wireless networks. A typical application of massive access is the cellular Internet of Things (IoT). Different from conventional human-type communication, massive access aims at realizing efficient and reliable communications for a massive number of IoT devices. Hence, the main characteristics of massive access include low power, massive connectivity, and broad coverage, which require new concepts, theories, and paradigms for the design of next-generation cellular networks. This paper presents a comprehensive survey of aspects of massive access design for B5G wireless networks. Specifically, we provide a detailed review of massive access from the perspectives of theory, protocols, techniques, coverage, energy, and security. Furthermore, several future research directions and challenges are identified.
