|---|---|---|
Interference mitigation scheme is studied for Device-to-Device (D2D) communication in cellular networks to improve the overall system capacity and spectrum efficiency. Firstly a lower bound of the neighbor distance is derived for a D2D UE according to the transmitter density and the QoS requirement of a D2D pair. By using this distance, a neighbor set can be chosen adaptively based on the interference condition so that the SINR of the D2D pair can be guaranteed at a desired probability. In addition, a metric, tolerant interference degree (TID) is defined to evaluate the permissible interference scope for a successful D2D transmission. Finally, an interference mitigation scheme based on greedy coloring is designed according to the derived neighbor distance and TID to mitigate interference among D2D pairs. The simulation results show that the throughput is significantly improved by proposed scheme compared with the existing freedom degree scheme (from 135% to 220%). And the resource efficiency is up to 4 times higher than that of the freedom degree scheme. © 2013 IEEE. |
