Abstract: A two-way wireless relay transmission method based on network coding is provided, wherein two end nodes and n relay nodes (wherein n≥2) which form a two-way wireless relay (TWRN) are divided into three different categories, so that any two nodes in a same category are separated by at least two relay nodes belonging to other different categories, and in a same timeslot, only nodes belonging to one category are allowed to transmit data packets and nodes of the other two categories should keep silent. As a result, the mutual interference caused by the simultaneous transmission of data packets between adjacent nodes is effectively avoided, and the mutual interference caused by the simultaneous transmission of data packets by the nodes belonging to a same category is reduced.
