Transmission Power Control and Relay Strategy for Increasing Access Rate in Device to Device Communication

In cellular networks, Device to (D2D) communication can improve spectral efficiency by enabling proximity users communicate directly without traversing the Base Station (BS). However, if not designed properly, interference generated D2D transmissions, may deteriorate quality of existing and users. this paper, we study transmission power control-based management increase access rate sum while guaranteeing Quality Service (QoS) requirements for both A four-step framework is proposed. First candidate groups, potentially admissible transmission, are arranged in order with respect their distance from BS required Signal Interference Noise Ratio (SINR). Next, upper lower bounds on transmitters calculated determine admissibility aspirant group subject QoS group, other scheduled user. Then, relay-based protocol considered admitting groups that cannot be admitted directly. Finally, each shared channel improved through iterative incrementation powers constraint all user rate. Simulation results show proposed many folds across scenarios as compared baseline schemes. Moreover, higher rates scheme translate into significantly rates.
