In this article, scheduling method of in-band Device-to-Device (D2D)communication underlaying cellular networks is studied.We address a single cell scenario in which several UEs have buffered data for local UEs in the same cell, and they are considered as potential D2D pairs.We propose an interference coordinated scheme, in which eNB selects D2D or UL/DL mode for each potential D2D pair, and allocates resources and power to D2D transmissions. The proposed scheduling method put no constraint on D2D distance or D2D number in a cell. The results show that spectral efficiency gain and overall user throughput are substantially increased with proper central coordination.
