Resource Allocation For Device-To-Device Broadcast Communication In Cellular Networks

Resource allocation issue is studied for broadcast mode of device-to-device (D2D) communication in cellular networks. We design systematic methods for transmission sub frame selection by broadcast UEs. Firstly, we design transmission patterns based on Hadamard matrix for the case with 8 D2D sub frames per D2D period. Then, we expand transmission patterns to the 16 sub-frame case. Accordingly, we design a distributed scheduling scheme, which can be naturally applied with a well designed transmission pattern set and takes into account spatial relationships between broadcast UEs. System level simulation shows the performance gain provided by the designed Hadamard-matrix-based transmission pattern set and the weighted collision minimization scheduling scheme.
