Abstract
D2D (Device to Device) communication is one of the key technologies that 3GPP intends to develop for 5G communication systems. It can not only reduce the burden of eNB, but also increase the capacity of the cellular network. It is also very useful when disasters happen, while the mobile communication systems are not available. Due to limited resource blocks (RB), researchers suggest that D2D pairs which can mutually tolerate the induced interference are grouped into a clique. Then the pairs in the same clique are assigned with the same RBs, so as to reuse RBs and increase the system capacity. The previous method evaluates SINR by using the locations of the devices and free space path loss formulae. In this way, however, the possible obstacles between a pair of devices are not considered. To deal with this problem, in this paper, we propose an approach where the SINR is evaluated by a practical way that employs the Reference Signals Received Power (RSRP) reported by the devices. Our approach can also prevent cliques from being formed improperly, so as to ensure its positive effect.
