（上面有一两个小错误~~~~）0Abstract: D2D(Device-to-Device) system deployment in the LTE Internet could improve resource utilization rate of the system effectively, but when sharing the resource of cellular system, the D2D system will generate interference problem between systems, which will influence the communication quality of cellular system and its total throughput. Based on the interface distinguish, a kind of D2D(Device-to-Device)access control optimization algorithm is proposed in this paper. This algorithm perceives interfaces from D2D communication to cellular subscribers at the base station terminal, which makes the D2d reuse the resource of cellular subscriber with the smallest annoyance value, and uses total throughput as a parameter when D2D system shares sources in order to rank the priority of the D2D dispatching. According to the real-time characteristics of D2D and cellular communication systems, two path loss models are introduced in this paper, and the simulation result demonstrates compared with random reuse algorithm, this algorithm can guarantee the communication quality of the cellular subscribers, increase the access success rate of D2D and enhance the system throughput on the premise of reducing total interfaces of the system.
Key words: D2D access; interference distinguish; priority; throughput; |
