近年来随着移动互联网业务和物联网业务的兴起与
发展,用户对移动宽带业务需求越来越旺盛,对移动通信
网络的接入速率和质量要求也越来越高,原有基于码分多
址(CDMA)的3G及其增强技术未来将无法满足业务发展
需要,因此3GPP及3GPP2组织自2004年开始启动长期
演进(LTE)/空口演进(AIE,后改名为超移动宽带UMB)项
目,旨在通过引入一些关键技术,如正交频分复用(OFDM)
调制技术、多入多出(MIMO)技术、混合自动重传请求

LTE系统网络架构更加扁平化简单化,减少了网络节点和系统复杂度,从而减小了系统时延,也降低了网络部署和维护成本。LTE系统支持与其他3GPP系统互操作。根据双工方式不同LTE系统分为FDD-LTE(Frequency Division Duplexing)和TDD-LTE (Time Division Duplexing),二者技术的主要区别在于空口的物理层上(像帧结构、时分设计、同步等)。FDD系统空口上下行采用成对的频段接收和发送数据,而TDD系统上下行则使用相同的频段在不同的时隙上传输,较
