5G encompasses the development of various key wireless communication technology standards. The development entails both\ntechnological advancement and social interaction. This paper analyzes 5G development and its significant shift from a strategy\npolicy to a user-oriented development showing the coplay of technology and society in China. Based on this theory, relevant\nproposals are recommended for future technical development and industrial regulation. Also, to increase the throughput and\nspectrum efficiency, channel assignment and load balance are considered. A hybrid routing protocol TOHRP (tree-based and ondemand\nhybrid routing protocol) and a distributed channel assignment algorithm LBCA (Load Based Channel Assignment) in the\nmultichannel environment are proposed and they solve the traditional problem of (1) waste of spectrum and (2) self-interference.\nThe computer-simulated experiment shows that the algorithm improves the performance.
