Device-to-Device (D2D) communications has been proposed to provide high data rate service in cellular networks via direct transmissions between clients. A cooperative D2D communications system allowing multiple D2D pairs overlaying a downlink cellular network simultaneously is considered. Each individual D2D transmitter will allocate its transmission power to decode-and-forward cellular users' traffic while superimposing its own signal. We provide accurate second order approximations and closed form expressions for the average achievable rates of both cellular user and individual D2D user for various spectrum accessing policies. We show that having multiple D2D users, the per-user rates of both cellular and D2D systems can be improved simultaneously.
