Introduction
The development of 5G technology has alleviated the challenges faced by the Internet of Things (IoT) and industrial networks to some extent. 5G provides three types of network services: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine type communications (mMTC), which provide essential network infrastructure conditions for emerging virtual/augmented reality, autonomous driving, smart grid, and IoT applications [1].
