Abstract

In a Device-to-Device (D2D) underlaying cellular system, interference cancellation is a key problem when uplink spectrums are shared and this problem becomes more complex in a multi-cell cellular network. In this paper, we propose an effective near-far interference avoidance scheme in a multi-cell cellular system. After monitoring the related control channels of a D2D subsystem and exchanging necessary information among neighboring eNBs, an eNB may stop scheduling the interfering cellular devices or facilitate power control mechanisms for the victim D2D users such that the inter-cell near-far interference can be mitigated. Simulations prove that our mechanism is effective and satisfying performance improvement can be obtained.
多蜂窝网络中D2D通信的有效干扰消除机制
在设备对设备(D2D)底层蜂窝系统中,当上行频谱共享时,干扰消除是一个关键问题,而在多蜂窝网络中,这一问题变得更加复杂。在本文中,我们提出了一种在多小区系统中有效的近远干扰避免方案。在监控D2D子系统的相关控制通道并在相邻的eNB之间交换必要的信息后,eNB可以停止调度干扰的蜂窝设备或为受害D2D用户提供功率控制机制,从而减轻蜂窝间近距离干扰。仿真结果表明,该机制是有效的,可以获得令人满意的性能改进。
