description The invention discloses a multi-user multi-mode D2D communication resource allocation method based on energy efficiency. The method comprises the following steps: 1) constructing a heterogeneous network model of a cellular network and a D2D communication shared spectrum; 2) calculating a D2D user signal-to-noise ratio and a cellular user signal-to-noise ratio in the heterogeneous network; 3) obtaining an energy efficiency expression; 4) selecting a transmission mode according to the distance between the D2D users and the signal-to-noise ratio; 5) searching an optimal relay node in the relay mode; 6) obtaining the transmitting power range of a signal transmitting end; 7) obtaining the optimal transmitting power and energy efficiency; 8) searching for an optimal cellular network link for a D2D user for multiplexing, so D2D communication can be better fused with cellular communication, the influence on the cellular communication is reduced, and the concept of green communication is better met. 本发明公开了一种基于能量效率的多用户
