D2d cellular network resource allocation method

The present invention discloses a method for D2D resource allocation in a cellular network, comprising the steps of: a first step, the UE measurement reporting; the second step, the base station is patterned to form a portfolio; a third step, the graph coloring, form a set; a fourth step , resource allocation, the resource allocation graph coloring elapsed after obtain m number of colors, i.e., all of the D2D is divided into m subsets, each subset D2D logarithmic range, each subset using the same sub-band resource; then resource allocation method based utility to maximize the frequency utilization. A cellular network according to the present invention D2D resource allocation method in comparison with the prior art: a detailed statistical analysis of detail, and can control a variety of situations, it is estimated that all possibilities.
