Description

D2D信号跳频方法及基站 技术领域
本发明涉及通信技术领域，特别涉及一种设备到设备(英文全称：Device to Device，英文缩写：D2D)信号跳频方法及基站。
背景技术
在长期演进(英文全称：Long Term Evolution，英文缩写：LTE)系统中，通信采取的是网络集中控制的方式，即终端的上下行信号都在网络的控制下进行发送和接收，终端和终端之间的通信，是由网络进行转发和控制的，终端和终端之间不存在直接的通信链路，这种方式下终端和网络的信号传输可以简称为设备到网络(英文全称：Device to Network，英文缩写：D2N)传输，如图1A所示，也就是说，两个终端之间的语音和信号等业务经过各自驻留的基站(普通基站或演进型基站)以及核心网进行交互。
移动通信系统未来发展中，为了更好的满足用户需求，提升设备之间信息交互的效率，引入了设备到设备(英文全称：Device to Device，英文缩写：D2D)通信技术，是指邻近的终端可以在近距离范围内通过直连链路进行信号传输，不需要中心节点(如基站)转发，如图1B所示。
D2D通信技术具有如下优势：
1、终端近距离直接通信方式可实现较高的信号传输速率、较低的时延和较低的功耗；
2、利用网络中广泛分布的通信终端以及D2D通信链路的短距离特点，可有效利用频谱资源；
3、D2D的直接通信方式能够适应如无线端到端等业务的本地信号共享需求，提供具有灵活适应能力的信号服务；
4、D2D直接通信能够利用网络中数量庞大且分布广泛的通信终端以拓展 网络的覆盖范围。
