Point-to-multipoint in-band full duplex wireless communication media access control method

A point-to-multipoint in-band full duplex wireless communication media access control method belongs to the wireless communication media access control method field, comprising: building connection between a wireless access point (AP) in a communication node and a station by two request frames RTS (Request-to-Send) and RRTS and one response frame CTS (Clear-to-Send), wherein the RRTS frame comprises data package 1 and data package 2 source addresses, a destination address and a data frame length; sending and receiving data packages at the same frequency at the same time by the AP and the station through the built communication link, wherein the transmission type comprises: 1) synchronous two-way link communication taking the station as the source node; 2) synchronous two-way link communication taking the AP as the source node; 3) asynchronous two-way link communication taking the station as the source node; 4) asynchronous two-way link communication taking the AP as the forwarding node.
