Based on the specifications released by 3GPP (3rd Generation Partnership Project), we use game theory to divide (D2D) device-to-device users using the same base station into different coalitions by calculating the signal to interference noise ratio, and by controlling the transmit power, we allow the reuse of the same spectrum resources, thereby reducing the overall D2D demand for resources. By calculating the resource requirement of the pairs that have more demand in a coalition and using it as the basis for resource allocation by the base station, we can satisfy the demand of all D2D pairs in the same coalition. Therefore, the overall system performance can be enhanced. The formation of coalitions and the power control method are the focus of this paper.
