Resource and power allocation for achieving rate fairness in D2D communications overlaying cellular networks

This paper presents a novel resource and power allocation scheme for device-to-device (D2D) communications overlaying cellular networks. The proposed scheme is implemented in two consecutive steps. The first step depends on implementing a vital algorithm that guarantees fairness in resource allocation among different D2D pairs by allocating the best subcarriers for every user such that every link’s data rate requirements can be satisfied. The...
