基于相对距离的D2D通信模式选择方案
A relative distance-based mode selection scheme for D2D communication
摘要
Abstract
Device-to-Device (D2D) communication is proposed as a transmission approach to improve resource efficiency and lighten the load of base station (BS) in heterogeneous networks. In this paper, two scenarios that the heterogeneous system contains relay node or not are considered, and the research focuses on the relative distance from D2D receiver to cellular user. The simulation results demonstrate that the probability of choosing underlay mode is inversely proportional to the system threshold value of Signal to Interference plus Noise Ratio (SINR), which is determined by system parameters. Moreover, the introduction of relay node can increase the probability of selecting underlay mode, as well as increase the spectrum efficiency.关键词
