D2D通信中一种资源分配与功率控制结合的方案
A Joint Method of Resource Allocation and Power Control for Device-to-Device(D2D) Communication
摘要
Abstract
By sharing the resource with cellular users,device-to-device(D2D) communication underlaying cellular network can improve the system resource utilization. But unfortunately, frequency reuse interfer-ence will be introduced between D2D users and cellular users. In order to coordinate the co-channel inter-ference,a combined strategy of resource allocation with power control is proposed in this paper. The pro-posed strategy allocates resource to D2 D links based on the overall system optimization for minimum inter-ference. Furthermore,each D2D transmitter can dynamically adjust the transmit power so as to improve the qualities of D2D pairs while ensuring the interference to cellular users to remain in a tolerable range. Sim-ulation analysis demonstrate that compared with the existing methods,the proposed method can effectively improve overall system performance.关键词
