Description

一种基站确定下行内环功控方式的方法及装置
技术领域
本发明涉及通信领域, 尤其涉及一种基站确定下行内环功控方式的方法 及装置。
背景技术
随着移动通信系统的演进, 用户的业务月良务质量已成为运营商的首要目 标, 业务服务质量影响了服务性能, 也决定了用户对业务的满意度。 提高用 户服务质量的一个非常重要的方面就是建立连接和信道分配时的时间延迟, 而且也会存在相对频繁的小数据包的业务, 因此需要考虑公共信道如何工作 的更有效。 比如减小上行链路和下行链路的信令延迟。 用户设备 (User Equipment, 简称为 UE )处于连接模式下的几种状态: CELL— FACH (小区— 前向接入信道) , CELL_PCH (小区 _寻呼信道)和 URA_PCH状态的下行信 令延迟 3GPP ( 3rd Generation Partnership Project, 第三代合作伙伴计划)标准 是通过引入下行高速分组接入( High Speed Packet Access, 简称为 HSPA )来 实现的, 而上行信令的延迟问题也是同样存在的。
为了减小上行的信令延迟, 需要考虑下述几个方面:
( 1 )减少 Idle模式, 减少 CELL— FACH, CELL— PCH及 URA— PCH状态 的用户面和控制面的等待时间;
( 2 )增加 CELL_FACH状态的峰值速率;
( 3 )减小 Idle、 CELL— FACH、 CELL— PCH、 URA— PCH和 CELL— DCH 状态之间的迁移延迟。
为了达到上述目的, 3GPP标准已通过引入在 CELL— FACH状态和 Idle 模式下使用 E-DCH ( Enhanced Dedicated Channel, 加强专用信道)来解决, 也即可以在 Idle模式、 CELL— FACH状态引入使用高速上行分组接入(High Speed Uplink Packet Access , 简称为 HSUPA ) 的方式。 为便于描述起见, 本 文中将 Idle状态和 CELL— FACH状态使用高速上行分组接入技术, 称为上行 链路加强 CELL— FACH技术。
上行链路加强 CELL— FACH技术的基本原理如下: 随机接入的发送原理 依然釆用 PRACH ( Physical Random Access Channel, 物理随机接入信道) 的 随机接入过程, 但是信道类型发生了改变, 也即在 Idle模式和 CELL— FACH 状态可以使用 E-DCH, CCCH ( Common Control Channel, 公共控制信道) I DCCH ( Dedicated Control Channel, 专用控制信道) I DTCH ( Dedicated Traffic Channel, 专用业务信道 )逻辑信道都可以映射到 E-DCH上进行发送。 E-DCH是映射到 E-DCH专用物理数据信道( E-DCH Dedicated Physical Data Channel, 简称为 E-DPDCH )上, 而 E-DPDCH信道又是需要通过 E-DCH专 用物理控制信道 ( E-DCH Dedicated Physical Control Channel , 简称为 E-DPCCH ) 才能正常工作, 而 E-DPCCH 又是基于专用物理控制信道 ( Dedicated Physical Control Channel, 简称为 DPCCH ) 的基础才能工作的, 因此在增强 CELL— FACH状态, 上行需要存在 DPCCH物理信道, 而为了配 合上行 DPCCH的正常工作进行链路同步, 下行也需要存在部分专用物理控 制信道( Fractional Dedicated Physical Control Channel简称为 F-DPCH )。对于 CELL— FACH状态和 Idle模式下上行引入了 DPCCH信道,下行引入了 F-DPCH 信道, 因此上下行之间需要进行内环功控, 才能保证在使用 E-DCH公共资源 的时间段内保持链路的同步。
目前对于专用态(即 CELL— DCH状态, 给用户分配专用资源)的 UE内 环功控区分上下行, 上行内环功控方式(Power Control Algorithm )有两种: 算法 1 (每个时隙都需要做内环功控)和算法 2 ( 5个时隙做一次内环功控); 下行内环功控模式(DPC MODE )也有两种: 模式 0 (每个时隙都需要做内 环功控)和模式 1 ( 3个时隙做一次内环功控) 。
目前 3GPP协议的 Uu口 ( UE和 RNC之间的接口 )定义了 Idle模式和 CELL— FACH状态 UE下行内环功控只能釆用模式 0 (即 DPC MODE =0 ) , 且无需无线网络控制器(Radio Network Control, 简称为 RNC )通过信令通 知 UE。 然而 RNC在 Iub口 ( RNC和 Node B之间的接口 )却存在 Idle状态 和 CELL— FACH状态下所使用的 DPC MODE配置信元, 且 DPC MODE可配 置两种模式 ( MODE 0和 MODE 1 ) , 且在 Iub口协议中并没有明确说在该种 场景下(即 UE处于 Idle模式或 CELL— FACH状态) Node B (节点 B, 基站) 只能使用 DPC MODE 0。 因此此种情况下就会存在下述问题: 如果 RNC为 DPC MODE配置了非零的模式,则 Node B就会按照 RNC所配置的非零模式 来接收 UE上行 DPCCH上的 TPC ( Transmit Power Control, 发射功率控制) 比特信息来做内环功控, 而 UE是固定釆用 MODE 0来发送 TPC比特信息, 这样就将会导致 Node B所调整的 F-DPCH发射功率不是 UE所期望接收的, 因而可能调整得过小导致链路失败而不能正常进行工作, 或者可能调整得过 大浪费了下行的功率资源并增加了对其他物理信道的干扰。
鉴于上述现有技术中存在的缺陷,有必要提供一种 Node B在 idle模式和 CELL FACH状态确定下行内环功控方式的方法,解决 Node B对 F-DPCH做 内环功控的方式和 UE反馈的 TPC比特方式不一致的问题。
发明内容

UE在 Idle模式或 CELL— FACH状态下可釆用模式 0向 Node B发送 TPC 比特信息。

公共 E-DCH 配置信息可以是在物理共享信道重配置请求消息中的公共 E-DCH系统信息 ( Common E-DCH System Information ) 中配置。
Node B对公共 E-DCH配置信息进行保存的步骤可以是: 当公共 E-DCH 系统信息中不包含下行内环功控模式(DPC MODE ) 的配置信息时, Node B 可选择所有的公共 E-DCH配置信息进行保存。
Node B对公共 E-DCH配置信息进行保存的步骤可以是: 当公共 E-DCH 系统信息中包含 DPC MODE的配置信息时 , Node B可选择除 DPC MODE的 配置信息以外的其它公共 E-DCH配置信息进行保存。
本发明还提供了一种基站确定下行内环功控方式的装置,应用于节点 B, 所述装置包括:
DPC模式确定模块, 其设置成在检测到有 Idle模式或者 CELL— FACH状 态下的 UE使用了 E-DCH信道时, 则确定釆用模式 0接收 UE在 DPCCH上 发送的 TPC比特信息, 并对 F-DPCH进行下行内环功控。
所述装置还可包括:
公共 E-DCH配置模块,其可设置成收到无线网络控制器通过物理共享信 道重配置请求消息通知的公共 E-DCH配置信息后, 选择其中的公共 E-DCH 配置信息进行保存,并向无线网络控制器返回物理共享信道重配置响应消息。 公共 E-DCH配置模块还可设置成,当无线网络控制器通过物理共享信道重配 置请求消息中的公共 E-DCH 系统信息配置公共 E-DCH配置信息、 且公共 E-DCH系统信息中包含 DPC MODE的配置信息时,选择除 DPC MODE的配 置信息以外的其它公共 E-DCH 配置信息进行保存; 否则, 选择所有的公共 E-DCH配置信息进行保存。
UE可在 Idle模式或 CELL— FACH状态下釆用模式 0向节点 B发送 TPC 比特信息。
本发明提供了一种 Node B在 Idle模式和 CELL— FACH状态确定下行内环 功控方式的方法及装置,使得 Node B对 F-DPCH做内环功控的方式和 UE反 馈的 TPC比特信息方式是一致的, 使得 F-DPCH可以用合适的发射功率进行 发送, 保证 UE能够同步 F-DPCH信道, 保持链路是可以正常工作的, 从而 保证 Node B能够正确接收 E-DPDCH上所发送的数据信息。 附图概述
