Description

一种扰码标识信令组的通知方法及系统 技术领域
本发明涉及长期演进高级系统（ LTE- Advanced, Long Term Evolution Advanced System ), 尤其涉及一种扰码标识信令组的通知方法及系统。 背景技术
在长期演进（ LTE, Long Term Evolution ) 系统中， 为了对信道的质量 进行测量和对接收的数据符号进行解调， 设计出了公共参考信号 （CRS, Common Reference Signal ), 接收侧可以利用 CRS对信道的质量进行测量， 从而确定接收侧是否进行小区重选和切换到目标小区， 并且在接收侧是连 接状态时进行信道质量的测量； 当干扰级别较高时， 接收侧的物理层可以 通过高层相关的无线链路连接失败信令断开与网络侧的连接。 在 LTE版本 10中引入了解调参考信号 （DMRS, Demodulation Reference Signal )和信 道状态信息参考信号 ( CSI-RS, Channel State Information Reference Signal ) 两种导频， 接收侧利用 DMRS进行数据的解调， 利用 CSI-RS对信道质量 进行测量， 从而反馈预编码矩阵指示器（PMI, Precoding Matrix Indicator ) /信道质量指示器（ CQI, Channel Quality Indicator ) /排列指示器（ RL Rank Indicator )等信息给网络侧。 这样的配置方法的优点是可以减少信道状态参 考信号的开销， 同时能够提高信道估计的准确性， DMRS 的其他优点是可 以实现接收侧的透明检测，即接收侧不需要知道 eNodeB发送所采用的预编 码权值。 特别是对于版本 10的接收侧采用传输模式 9, 可以利用 DMRS来 估计层间干扰， 从而利用先进的接收机来减少层间干扰带来的检测误差。
在未来通信技术的发展中， 需要实现小区的 "微化 "， 即在以后的场景 中，不但要考虑均匀分布的 Macro-eNodeB,还要考虑不均匀分布的微小区， 例如微小区 （ Pico ), 家庭基站（ HeNodeB )、 中继站 （ Relay )等； 在这种 不均匀分布的微小区的分布场景中， 不但存在 Macro-eNodB之间的干扰， 海存在 Macro-eNodeB与 Pioc、 HeNodeB、 Relay等微基站之间的干扰。 由 于 Macro-eNodeB的发送功率较大， 所以这种异构网下的干扰更加严重， 因 此小区之间避免 /消除干扰的技术将成为 LTE版本 11的一个研究重点。 R10 的多输出多输入（ MIMO, Multi-Input-Multi-Output )增强也主要基于单小 区的增强， 而且在考虑异构网的场景时， 也只考虑了通过简单的时分的方 式来避免多小区之间的干扰。在 LTE版本 11中可能引入多点协作协调多点 传输（ COMP, Coordinated Multi-Point Transmission )技术来避免小区之间 的干扰， 特别是异构网下多小区之间的干扰。
多点协作 COMP技术是通过波束空分的方式来避免小区之间的干扰 的， 目前， 其主要技术可以分为： 多点协作联合发送和多点协作协同调度 / 多点协作协同波束。 由于采用多点协作联合发送时， 不同的参与发送的协 作小区需要采用相同的扰码序列来对发送的数据和 DMRS进行加扰， 如果 不同参与协作小区采用不同的扰码序列， 就会造成接收侧无法合并多个 d、 区传输的信号， 并获得合并分集增益； 而且， 当采用多点协同波束的方法 来减少不同小区接收侧之间的干扰时， 如果不同小区所使用的 DMRS扰码 不同， 就会导致不同小区的接收侧不能通过 DMRS来准确的估计出接收侧 之间的干扰， 从不能利用先进的接收技术来压缩这种干扰， 或者在动态小 区选择（DCS, Dynamic Cell Selection ) 时如何动态的通知接收侧不同发送 侧的参考信号和数据扰码序列。 发明内容
