Description

一种实现在多天线系统中进行测量的装置和方法 技术领域
本公开涉及无线通信技术领域，更具体地，涉及一种实现在多天线系统中进行测量的装置和方法。
背景技术
4G中，C-RAN(Centralized,Cooperative,Cloud&Clean-Radio Access Network)架构一般由集中BBU(Base Band Unit，基带单元)、拉远RRU(Radio Remote Unit，射频拉远单元)组成，而前者又由物理层，层二，包括MAC(Medium Access Control，媒体接入控制)，RLC(Radio Link Control，无线链路控制)，PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)等子层，以及层三，如RRC(Radio Resource Control，无线资源控制)等协议功能层构成。BBU、RRU间的前传接口采用CPRI(Common Public Radio Interface，通用公共无线电接口)，由于CPRI接口传输的是经过物理层编码调制等处理后的IQ信号，CPRI接口对传输时延和带宽都有较大的要求。若未来空口速率提升到数十Gbps后，CPRI接口的流量需求将上升到Tbps级别，对网络部署成本和部署难度都带来了巨大的压力。因此，需要重新定义BBU和RRU的功能，比如将层二的用户面部分功能部分放在BBU、部分放在RRU。本文中对重新规划功能后的BBU和RRU分别命名为CU(Centralized Unit，集中单元)和DU(Distributed Unit分布单元)。示意图如附图1所示。其中分布单元也可以称为远端单元。
未来通信系统朝着无缝广域覆盖，大容量热点，低功耗的大量连接和低延迟的高可靠性等目标发展，必然会采用高频段、大带宽，而高频段由于其传播特性的原因，覆盖范围往往很小，因此大规模天线阵列MM(massive MIMO)往往被用来提升链路增益进而提升覆盖。大规模天线阵通过采用波束赋形(beam forming)技术，可以大大提升链路性能，自然达到提升覆盖和容量的目的，被认为是提高现代无线通信系统传输速率的一种有效方式。未来通信系统中大规模天线阵的天线单元数可达数百甚至上千根，公共信道及专用信道都可能是基于波束(beam)覆盖的。
测量对于通信系统移动性管理是非常重要的，传统的测量往往要借助控制面RRC(Radio Resource control，无线资源控制)的控制信令，以切换为例，从测量配置、切换触发、目标小区接入等都需要控制信令来实现，切换需要的时间往往达到百毫秒级甚至秒级。而对于未来的无线通信系统，传统的完全依靠控制面信令进行测量的方法必然不能达到未来无线通信系统大容量或者低时延高可靠的目标和要求。
