DETAILED DESCRIPTION For convenience of understanding, terms involved in the disclosure are introduced first. 1. Full Duplex Communication The full duplex communication may be divided into frequency division multiplexing (FDM) and time division multiplexing (TDM). The FDM means that an entire transmission frequency band may be divided into several frequency channels, each UE may occupy one frequency channel to send data, and there is a guard band between the frequency channels. In addition, the TDM means that time may be divided into small time slices, each time slice is divided into several channels (slots), and each UE may occupy one channel to send data. 2. Radio Resource Control (RRC) The RRC, referred to as radio resource management (RRM) or radio resource allocation (RRA), performs wireless resource management, control and scheduling by certain strategies
