Abstract

Device to device (D2D) communication is a key technology of 5G mobile communications. It allows devices to communicate by using direct links, rather than travelling all the way through base stations. It can not only reduce the burden of base station, but also increase the capacity of cellular networks. In order to efficiently use the limited resource blocks (RB), researchers suggest that D2D pairs which can mutually tolerate the induced interference be grouped into a clique and reuse the assigned RBs. As a result the system capacity can be improved. Most methods evaluate SINR in accordance with device locations and free space path loss formula. However, between the two devices of a D2D pair, there may be obstacles which lead to severe signal attenuation. But these obstacles are generally ignored in path-loss formulas. To deal with this problem, we propose a practical approach which evaluates SINR using the reference signal received power reported by devices during the proximity discovery phase.
