Description

一种测量路径损耗的方法、 系统及设备
技术领域
本发明涉及移动通信领域， 尤其涉及一种测量路径损耗的方法、 系统及设 备。 背景技术
随着移动通信的发展， 用户对移动通信的性能要求越来越高。 目前， 在第 三代移动通信系统中， 下行的通信能力已经得到很大的提升。 为了提高上行接 入能力， 第三代移动通信标准化伙伴项目 （3GPP, 3rd Generation Partnership Project )组织相继在在版本 6( Release6 )和版本 7( Release7 )对频分双工（ FDD, Frequency Division Duplex )和时分双工 ( TDD, Time Division Duplex ) 引入 了上行增强（ Enhanced Uplink )技术，也称为高速上行分组接入技术（ HSUPA, High Speed Uplink Packet Access )， 其目的为提高上行的通信能力。
在 TDD HSUPA技术中， 引入了增强上行物理信道 E-PUCH, 用于传输上 行增强专用信道 E-DCH ( Enhanced Dedicated Transport Channel )数据； 引入 了上行增强专用信道的上行控制信道 E-UCCH ( E-DCH Uplink Control Channel ), 用于传输针对 E-DCH数据的控制信息， 包括传输块大小指示、 重 传序列号 RSN、 混合自动请求重传 HARQ进程号。 在 HSUPA系统中， 为了 辅助系统的资源调度，需要终端上报调度请求信息 SI( Scheduling Information ), 其中包含本邻区路径损耗相关信息 SNPL ( Serving and Neighbour Cell Pathloss ), 该信息主要反映目标小区的用户在发射功率一定时， 对本小区和同 频的邻小区的干扰水平的比例， 其中包括了本小区路径损耗、 同频的邻小区路 径损耗信息。
对于 TD-SCDMA ( Time Division- Synchronization Code Division Multiple Access, 时分同步码分多址接入） 系统， 为了扩大系统容量， 实际组网时每个 小区会有多个频点， 称为 N频点系统或者多频点系统。 在每个小区的多个频 点中， 其中有一个频点是主频点， 其它频点为辅频点， 终端可以在主频点或者 辅频点上与系统进行通信。 主公共控制物理信道 P-CCPCH ( Primary Common Control Physical Channel )在主频点上承载， 辅频点上没有 P-CCPCH信道。 终 端测量路径损耗信息是通过对 P-CCPCH接收信号的测量获得。 因此为了测量 路径损耗信息， 终端必须到主频点上测量。
为了测量 SNPL, 终端必须测量本小区的路径损耗和同频的邻小区的路径 损耗， 而测量同频的邻小区的路径损耗， 需要测量与该终端工作频点相同的频 点所在小区中的主频点上的路径损耗，终端的工作频点指的是终端上行链路所 使用的频点， 近似地， 认为主频点到终端的路径损耗， 和辅频点到终端的路径 损耗基本相等。
然而， 目前标准上， 终端可能无法准确的根据信令通知的同频、 异频邻小 区列表中包含的信息， 获取最终确定需要用于 SNPL测量的邻小区信息，从而 影响 SNPL的计算， 导致终端上报调度请求信息 SI ( Scheduling Information ) 时无法让系统准确了解当前终端的通信环境， 不利于系统的资源调度， 而且会 影响到整个系统的上行干扰控制性能。 发明内容
本发明的目的在于提出一种测量路径损耗的方法、 系统及设备，使得终端 能准确测量同频的邻小区的路径损耗，以克服现有技术中终端上报调度请求信 息 SI时无法让系统准确了解当前终端的通信环境、 系统无法有效地进行资源 调度、 系统无法控制上行干扰等一个或多个问题。
为了达到上述目的， 本发明的实施例公开了一种测量路径损耗的方法， 包 括以下步骤：
终端接收基站发送的本邻区路径损耗 SNPL测量信息；所述终端根据所述 SNPL测量信息测量与所述终端的工作频点同频的邻小区的路径损耗， 并计算 SNPL值； 所述终端将所述 SNPL值发送给所述基站。
本发明的实施例还公开了一种测量路径损耗的系统， 包括： RNC、基站以 及终端，
所述 RNC, 用于才艮据所述终端的工作频点， 确定与所述终端的工作频点 同频的邻小区的主频点信息， 形成所述 SNPL测量信息， 并发送给所述基站； 所述基站，用于向所述终端发送消息，其中所述消息包括所述 SNPL测量信息， 并用于接收所述终端反馈的 SNPL值； 所述终端， 用于根据所述 SNPL测量信 息测量与所述终端的工作频点同频的邻小区的路径损耗， 并计算 SNPL值， 同 时将所述 SNPL值发送给所述基站。
本发明的实施例还公开了一种 RNC, 包括：
频点信息获取模块， 用于根据所述终端的工作频点， 获取与所述终端的工 作频点同频的邻小区的主频点信息； 消息配置模块， 用于根据所述终端的工作 频点同频的邻小区的主频点信息， 配置 SNPL测量信息并发送给基站， 用于指 示终端进行邻小区的路径损耗测量。
本发明的实施例还公开了一种终端， 包括：
接收模块， 用于接收 SNPL测量信息； 测量模块， 用于根据所述 SNPL测 量信息对与所述终端工作频点同频的邻小区的路径损耗进行测量， 得到 SNPL 值；
发送模块， 用于将所述测量模块得到 SNPL值发送给基站。
本发明的实施例提出的技术方案具有以下一个或多个优点：本发明的实施 例公开的技术方案， 高效简单易于实现， 对现有系统的影响很小， 只需要在现 有系统的消息上携带相关信息即可实现对同频的邻小区的路径损耗准确测量。 利用本发明提出的技术方案， 终端能准确测量出同频的邻小区的路径损耗，使 得系统能准确了解当前终端的通信环境，有利于系统的资源调度， 同时也便于 系统对上行干扰的控制。 此外， 利用本发明提出的技术方案， 可以用于对同频 干扰的测量、 统计、 消除等， 有利于进一步优化系统性能。 附图说明

下面将详细描述本发明的具体实施方式， 所述实施例的示例在附图中 示出。 下面通过参考附图描述本发明， 这仅用于解释本发明， 而不能解释 为对本发明的限制。
本发明的实施例公开了一种测量路径损耗的方法， 包括以下步骤： 终端接收基站发送的本邻区路径损耗 SNPL测量信息； 所述终端根据 所述 SNPL测量信息测量与所述终端的工作频点同频的邻小区频点的路径 损耗， 并计算 SNPL值； 所述终端将所述 SNPL值发送给所述基站。
在本发明的各个实施例中， 所述终端的工作频点均指终端上行链路所 使用的频点。
如图 1 所示， 为本发明的实施例测量路径损耗的方法的实施方式流程 图。
步骤 S 100: 终端接收基站发送的 SNPL测量信息。 在该步骤中， 终端 接收基站发送的本邻区路径损耗 SNPL测量信息， 指示终端需要测量的同 频的邻小区的路径损耗。

Message ) 或者系统信息块 （ System Information Block )把终端的同频的邻 小区信息列表 （ Intra-frequency cell info list ) 和异频小区信息列表 ( Inter-frequency cell info list )通知终端。 由于 N频点系统中只有主载波存 在 P-CCPCH广播信道， 必须对主载波进行测量才能得到路径损耗， 才能计 算 SNPL。 当前终端的工作频点可以是服务小区的主频点，也可以是服务小 区的辅频点， 为了测量终端工作频点同频的邻小区的路径损耗， 下面本发 明给出具体的实施例。
