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. In the past few years, it has received considerable attention in academia and industry. This Special Issue (SI) of the IEEE Journal on Selected Areas in Communications (JSAC) on Massive Access for 5G and Beyond contains the latest results of researchers, industry practitioners, and individuals working on related research problems. Due to the extremely high response to the Call for Papers, this SI is split into two parts. The first part includes a guest editor-authored survey paper and 17 technical papers focusing on access models and access protocols, while the second part contains 18 papers focusing on access techniques and coverage enhancement approaches. We sincerely thank the authors, reviewers, JSAC staffs, and the Senior Editor, Prof. Wayne Stark, for their effort and time in preparing this SI.

来宾社论大规模访问5G及更高版本-第一部分

大规模访问（也称为大规模连接或大规模机器类型通信（mMTC））是第五代（5G）和5G（B5G）及以后的无线网络的主要使用案例之一。在过去的几年中，它在学术界和工业界受到了相当大的关注。IEEE关于5G及以后大规模访问的通信领域精选期刊（JSAC）的特刊（SI）包含研究人员，行业从业人员和从事相关研究问题的个人的最新成果。由于对论文征集的响应非常高，该SI分为两个部分。第一部分包括客座编辑撰写的调查论文和17篇针对访问模型和访问协议的技术论文，而第二部分则包含18篇针对访问技术和覆盖增强方法的论文。
