| description | The invention provides a D2D communication channel allocation method in an ultra-dense scene. The method comprises the following steps: constructing a D2D communication system model; determining a channel allocation priority according to the QoS demand and the transmission performance of the cellular user; the cellular users traverse all discrete transmitting powers and the maximum reusable D2D user number of channels; determining the distribution priority of the D2D users; performing D2D user channel allocation, and allocating the D2D users to cellular user channels according to an allocation priority sequence until the allocated D2D users reach the maximum reusable D2D user number of the channels; comparing system performance benefits, and determining a channel allocation scheme and cellular user power selection; and removing the D2D users and the corresponding channels which have completed channel allocation, updating the queue, traversing all the channels, and outputting a channel allocation result.
