This letter proposes a novel distributed opportunistic scheduling with interference mitigation antenna selection (DOS-IMAS) to achieve the optimal multi-user diversity in ultra-dense device-to-device (D2D) networks. The proposed DOS-IMAS opportunistically and sequentially selects ${K}$ D2D pairs in a fully distributed manner based on interference and desired signal power thresholds. We prove that the proposed DOS-IMAS achieves the optimal multi-user diversity ${K}$ log SNR log ( ${n}$ ) under $n=\omega \left({(MN)^{\frac {1}{\kappa -1}}\mathsf {SNR}^{\frac {K(K-1)}{1-\kappa }}}\right)$ , where SNR , n , M , and N denote the signal-to-noise ratio, the total number of D2D pairs in the network, the number of transmit antennas, the number of receive antennas, respectively, and $\kappa \in $ (0, 1). The numerical results validate that the proposed technique outperforms existing scheduling schemes in terms of sum rates.
