Interference Canceling Power Optimization for Device to Device Communication

We consider D2D communication underlying cellular uplink communication when single stage interference cancellation receivers are available to improve local service. The interference cancelation configurations and transmission powers are jointly optimized in the network to maximize a network utility. Each receiver may or may not cancel the signal from the dominant interferer. With N-1 D2D pairs and one cellular transmitter, there are 2^N possible IC state combinations. A scheduling problem is formulated to allocate resources to these combinations, and network utility is maximized by iterating between scheduling weight and transmit power. In a simulation where sum rate or proportionally fair network utility is maximized, we observe significant gains in the spectral efficiency enjoyed by the users.
