The invention provides a sub-channel allocation method based on an alliance game for a full-duplex in-band millimeter wave IABN with D2D, and relates to the technical field of wireless communication networks. The method comprises the following steps: constructing a directed graph with D2D downlink full duplex in-band millimeter wave IABN, determining all concurrent transmission links including a backhaul link, an access link and a D2D link, and randomly initializing a sub-channel alliance; performing interference analysis on links in each alliance through the initialized alliance segmentation, and calculating the actual reachable rate and the alliance total benefit of each concurrent link in the current alliance segmentation state; all link players in the alliance are subjected to alliance switching according to the alliance switching criterion based on the preference degree of the link players and the alliance switching criterion based on the QoS requirement of the transmission rate of the link players until
