Description

一种载频间协作方法及装置 技术领域
本申请涉及但不限于通信领域。
背景技术
智能手机、平板电脑等智能终端的出现，导致了无线通信网络数据应用业务的蓬勃发展，如云计算、物联网、移动互联网、手机视频电话、手机视频会议、在线游戏、在线视频、在线音乐、图片下载、微博、社区等，也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。根据权威机构预测，未来10年，无线数据业务将增长500～1000倍，平均每年增长1.6～2倍。
提升无线网络容量的方法有多种，常用的有：(1)增加频谱带宽；(2)加强业务分流；(3)提高网络密度；(4)提升频谱效率。
增加频谱带宽的方式是快速提升无线网络容量最直接的方法。传统的无线通信系统使用的频谱资源范围主要集中在低频段上(例如6GHz以下)，具有可用频谱资源少、覆盖范围大、电磁波绕射能力强等特点，设计时需要优先考虑提升频谱效率。为了满足未来的发展需求，第五代移动通信系统中，高频段(例如6GHz以上)的开发利用是必然的趋势，高频段具有可用频谱资源多、传输能量衰减快、电磁波绕射能力差等特点，其设计思想应该优先考虑覆盖能力而不是频谱效率。
目前的载频协作主要集中在低频段上，由于载频的特性比较一致，所以在第四代移动通信系统时采用的方式也非常简单。
