Abstract

The ever-increasing data rate and number of connections in mobile communication offer exciting user experiences in everyday life. Technological developments for beyond-5G and 6G wireless communications have occurred in recent years. Compared with current 5G networks, the next-generation network aims to deliver 10–1,000 times higher data rates with improved enhanced mobile broadband, a 1/10th lower latency based on ultrareliable and low-latency communications, and our society is expected to undergo a revolutionary change within the coming of a new era [1] , [2] .
