Description

一种实现通信模式调整的方法、微基站及宏基站 技术领域
本文涉及无线通信系统的长期演进技术中实现通信模式调整的技术，尤指一种实现通信模式调整的方法、微基站及宏基站。
背景技术
随着智能手机、平板电脑等智能终端的应用发展，诸如云计算、物联网、手机视频电话和会议、在线游戏、在线音乐和图片下载等带动了无线通信网络用户的大规模增加，导致无线数据业务的爆炸式增长。根据预测，未来10年，无线数据业务将增长1000倍，平均每年增长2倍。
为适应无线数据业务的增长，目前，主要通过增加频谱带宽、加强业务分流、提高网络密度、提升频谱效率等提高无线通信网络容量。通过提高无线通信网络容量，可以提高正常环境下无线数据业务的服务质量。超密集网络是第五代移动通信系统中的关键技术，其中微基站(发射功率比较低的站点，也称为小基站，例如飞蜂窝(femto cell)、微蜂窝(micro cell)、小小区(small cell)、中继站(relay station)等)被大规模部署，考虑到成本、施工环境等因素，它们与上层网元之间的回传(backhaul)链路或基站之间的前传(fronthaul)链路很难全部通过光纤或有线方式实现，因此需要考虑通过无线传输的方式实现backhaul或fronthaul链路。虽然无线传输具有时延短、部署灵活的优点，但是需要占用宝贵的无线频谱资源，特别是基于同频带信号传输(in-band)方式实现时，微基站和上层网元通信与微基站和下属终端通信使用的是相同的无线频带，彼此之间通过时分的方式占用无线频带，会极大地降低整个系统的容量。例如，宏基站与微基站通过无线链路实现了in band方式的backhaul，微基站在给下属终端发送数据的同时，接收宏基站给它发送的数据。
同频同时全双工(Full-Duplex)是近几年提出的新型双工技术，其核心是通过高效精细的自干扰和互干扰消除等技术，实现全双工系统中的同频干扰消除，保证正常的信号接收，从而实现收发同频同时。同频同时全双工模 式(以下简称为全双工模式)较传统的频分双工模式或时分双工模式，能够减少一半的频率浪费，是一个未来非常有价值的移动新技术。在微基站侧引入全双工模式，可以提高无线频谱资源的利用率。但是，让微基站每时每刻都开启全双工模式，在系统工作过程中缺乏灵活性，针对网络负载的变化，开启全双工模式并不能发挥其工作性能，反而给微基站带来了不必要的计算复杂度和功耗，同时也增加了微基站下属终端的负担；例如，全双工模式下需要微基站在给下属终端发送数据的同时，需要尝试解码宏基站给该微基站发送的下行数据，给微基站带来了不必要的计算的复杂度；网络负载比较轻时，微基站没有必要开始全双工模式便可以满足系统的整体性能要求，此时如果微基站处于全双工模式，会导致微基站在尝试接收其他网络节点发送的数据的同时还要给自己的下属终端发送数据，但实际上其他网络节点并没有给它发送任何数据，造成了微基站不必要的功耗。
