| 摘 要： | 随着移动通信的不断发展,5 GHz以下带宽分配已经十分拥挤,由于可用于移动通信的频谱资源有限,为满足无线通信发展的需要,可以用终端直通技术(D2D,Device-to-Device)来提高频谱利用率,并可以减少和基站通信的负担,这是新一代无线通信发展的趋势。但是在D2D通信系统中所选择的模式是十分关键的问题。这里给出了蜂窝模式和直通模式这2种通信模式,为了能更好地选择D2D的工作模式,通过仿真比较了这2种模式性能的优劣。

| Abstract: | With the development of mobile communication,the allocation of bandwidth under 5 GHz is crowded due to the limited frequency resource for mobile communication.Thus D2D（Device to Device） communication is used to improve the spectrum efficiency and reduce the burden of communication between the user and the base-station.This is also the development trend of new-generation wireless communication.However,the choice of mode in D2D communication is a critical problem.This paper describes in detail the cell mode and the D2D mode,and also compares their advantages and disadvantages by simulation. |
