Embodiment
[0046] refer to image 3 , a multi-user multi-mode D2D communication resource allocation method based on energy efficiency, comprising the following steps:
[0047] 1) Construct a heterogeneous network model in which the cellular network and D2D communication share spectrum: such as figure 1 As shown, it is assumed that there are N cellular users, M pairs of D2D users and K idle relay users in the heterogeneous network where the cellular network and D2D communication share spectrum, and N≥M, and the cellular user set uses N={1,2, ...,n} represents, the user set of D2D users is represented by M={1,2,...,m}, and the relay user set is represented by K={1,2,...,k};
[0048] 2) Calculate the D2D user SNR and the cellular user SNR in the heterogeneous network: calculate the D2D user j’s and cellular user i's and the D2D user j after the introduction of the relay user and cellular user i's When the D2D communication is in the direct mode, the D2D user j's with cellular use...
