Description

一种控制上行闭环发射分集的方法和系统 技术领域
本发明涉及通信领域, 具体涉及一种控制上行闭环发射分集的方法和 系统。 背景技术
高速上行链路分组接入(HSUPA )是 3GPP版本(Release, R ) 6所引 入的增强型技术, 旨在提高上行链路的传输速率, 是对宽带码分多址 ( WCDMA )上行系统性能的增强和扩展。 HSUPA通过引入快速上行混合 重传 (HARQ )、 基于节点 B ( Node B ) 的上行调度以及与之前版本更加简 单的多码传输提高上行系统传输性能, 使上行链路的最大峰值传输速率可 以达到 5.76兆每秒 ( Mbps )。
多天线技术通过在发送端和 /或接收端使用多根天线来实现更高的系统 容量、 更广的小区覆盖以及更好的业务质量。 发送端和 /或接收端的多根天 线既可以用来实现发送或接收分集也可以用来实现空间复用。 其中, 发射 分集技术是一种在发送端发送至少 2个含有相同信息的信号的无线通信领 域的抗衰落技术。 这些承载相同信息的信号来源于至少 2个相互独立的信 号源。 发射分集技术依据其发射信号样值的结构与统计特性以及其所占无 线资源的不同, 可以划分为空间、 频率、 时间 3大基本类型, 也可以是这 3 种类型的相互结合。
发射分集技术依据接收端是否需要向发送端反馈分集需要的参数分为 开环发射分集模式和闭环发射分集模式。 开环发射分集模式下, 接收端不 向发送端反馈任何额外的与发射相关的信息, 发送端可以自行使用相应的 编码技术(例如简单的空-时编码) 完成发射分集。 闭环发射分集模式下, 接收端需要使用反馈信道反馈给发射端一个与发射分集相关的参数(例如 发射分集所需的预编码向量, 通过预编码指示信息指示), 发送端在接收后 使用该反馈信息完成发射分集。
目前在 3gpp会议上已经达成共识: 当用户设备 ( UE )配置了高速链路 分组接入信道, 采用高速共享控制信道命令来控制上行闭环发射分集的激 活与去激活, 但是如果用户设备只配置了专用信道, 那么就不能采用高速 共享控制信道命令。 因此有必要研究如何在用户设备只配置了专用信道的 情况下如何激活 /去激活上行闭环发射分集, 但目前还没有确定的方法。 发明内容

参见图 4, 图 4为无线网络控制器动态控制上行闭环发射分集的激活 / 去激活的流程图, 该流程包括如下步驟:
步驟 400, 无线网络控制器获取用户设备发送的数据。
步驟 401 , 如果接收到的数据质量较差, 在用户设备支持上行闭环发射 分集的条件下, 激活上行闭环发射分集。
评价接收到的数据质量较差的方法有多种, 如接收到的误块率大于预 设门限值, 或者统计重传率高于预设门限值。
参见图 5 , 图 5为无线网络控制器动态控制上行闭环发射分集的激活 / 去激活的流程图, 该流程包括如下步驟:
步驟 500, 无线网络控制器获取用户设备发送的数据。
步驟 501 ,如果接收到的数据质量较好, 并且当前用户设备已经激活了 上行闭环发射分集, 那么无线网络控制器去激活上行闭环发射分集。
评价接收到的数据质量较好的方法有多种, 如接收到的误块率小于预 设门限值, 或者统计重传率小于预设门限值。
由以上各实施例可见, 本发明控制上行闭环发射分集的系统中, 无线 网络控制器、 节点 B以及用户设备能够进行如图 6所示的流程, 该流程包 括以下步驟:
步驟 610: 获知用户设备只配置了专用信道。
步驟 620: 由无线网络控制器决策并向节点 B发送用于激活 /去激活上 行闭环发射分集的用户面帧; 以及, 由无线网络控制器决策并向用户设备 发送用于激活 /去激活上行闭环发射分集的控制命令。
综上所述可见, 无论是方法还是系统, 本发明控制上行闭环发射分集 的技术, 保证在用户设备只配置了专用信道的情况下能够激活 /去激活上行 闭环发射分集。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
