5G大规模机器类通信中的传输技术

摘要

机器类通信(MTC)是物联网(IoT)的潜在挑战,作为MTC分支的大规模机器类通信(mMTC)涉及IoT的大规模部署问题,是5G的重要应用场景之一.针对mMTC场景中的传输技术,重点介绍了mMTC场景中的数据采集技术及其在无线传感器网络(WSNs)中的应用.此外,还指出了mMTC技术所面临的一些挑战.%Machine type communication (MTC) is a potential challenge in internet of things (IoT). As the branch of MTC, massive machine type communication (mMTC) involves large-scale deployment of IoT which has been an important application of 5G. In this paper, we focus on the transmission technologies of 5G massive machine type communication, and mainly introduce the technologies of data acquisition in mMTC and its applications in wireless sensor networks (WSNs). Moreover, some challenges of mMTC technology are pointed out.
