Description

一种资源配置的方法、 装置和系统
本申请要求于 2008 年 10 月 31 日提交中国专利局、 申请号为 200810217501.X, 发明名称为 "一种资源配置的方法、 装置和系统" 的中国 专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及移动通信技术，特别涉及一种资源配置的方法、装置和系统。 背景技术
在移动通信领域中， 随着各种业务的发展， 用户对于数据传输的速度提 出了越来越高的要求。 为了支持更高速率的数据业务、 更低的时延、 更高的 吞吐量和频谱利用率， 提出了两种新的技术， 高速下行分组接入（HSDPA, High Speed Downlink Packet Access )和高速上行分组接入（HSUPA, High Speed Uplink Packet Access )技术。
HSUPA技术引入了新的物理信道，新的物理信道中包括用于承载增强专 用信道（ E-DCH, Enhanced Dedicated Channel )的上行数据信息的 E-DCH专 用物理数据信道 ( E-DPDCH, E-DCH Dedicated Physical Data Channel ) , 以 及用于承载 E-DCH的上行信令信息的 E-DCH专用物理控制信道（ E-DPCCH, E-DCH Dedicated Physical Control Channel ) 。
在引入上述新的物理信道之前， 由于数据速率提高， 传输数据的数据块 增大， 使得根据专用物理控制信道 （ DPCCH , Dedicated Physical Control Channel )进行信道估计的性能变差，无法满足高速数据传输解调的性能要求。 造成上述问题主要是因为： 为了使上行高速传输的性能达到最优， 就需要将 E-DPDCH与 DPCCH之间的功率差控制在一定的范围内， 而保证该功率差被 控制在一定的范围内就需要提升 DPCCH的功率， 同时也就需要提升 DPCCH 信噪比（ DPCCH SIR )。然而调整信噪比目标值（ SIRtar, Signal-to-Interference Ratio Target )的外环功率控制 ( OLPC, Out Loop Power Control )过程是一个 慢速的过程， 如果 SIR的调整过快， 就可能会导致 OLPC无法跟上 SIR变化 的需求。 因此， 可能会出现高速情况下需要较大的 SIR时， SIRtar仍处于较 低的值。 此时， 会导致高速情况下误码率大幅度提升， 并严重影响吞吐量。
因此， 在引入 E-DPCCH后， 为了提高信道估计的准确度， 将 E-DPCCH 也加入到信道估计中。在 E-DPCCH也加入信道估计时， 通过 E-DPCCH的功 率抬升（ power boost )特性使得 E-DPCCH与 DPCCH的功率差可以控制在性 能允许的范围内， 同时也可以满足功率变化时信噪比的要求。 由此， 信道估 计的准确度大大提高。
但是在现有技术中， 无线网络控制器（ Radio Network Controller, RNC ) 无法在进行资源配置时， 为具有 E-DPCCH power boost能力的 UE的无线链 路分配 E-DPCCH power boost资源。从而导致 UE即使具有了 E-DPCCH power boost能力， 无法利用 E-DPCCH 的 power boost特性进行信道估计， 仍然会 存在高速数据传输时， 信道估计不准确， 数据解调性能变差的问题。 发明内容

为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本 发明作进一步地详细描述。
在下述各实施例中， 无线通信系统以 WCDMA ( Wideband Code Division Multiple Access, 宽带码分多址）系统为例， 但可以普遍应用在其 他无线通信系统中， 例如应用在 LTE ( Long Term Evolution, 长期演进项 目 ） 系统中。 在其他无线通信系统中的 RNC、 Node B和 UE具有不同的 名称， 但也可以适用本发明实施例提供的技术方案。
在 UE与 Node B之间建立无线资源控制连接 ( Radio Resource Control Connection, RRC Connection )时， UE会在 RRC连接请求（ RRC Connection Request )消息中或者 RRC连接建立完成（ RRC Connection Setup Complete ) 消息中， 向 RNC上报该 UE是否具备 E-DPCCH power boost能力。 但是， 在 RNC与 Node B同步 Node B的配置和能力信息时， Node B可能不会主 动上报该 Node B是否具有 E-DPCCH power boost能力。因此，会造成 RNC 无法正确获知 Node B的能力信息， 无法正确配置无线资源。
例如， RNC可能会默认 Node B没有上报具有 E-DPCCH power boost 能力就是不具有该能力， 则在进行无线链路（Radio Link, RL ) 配置或者 RL重配时，不会通知 Node B为当前 UE的无线链路分配 E-DPCCH power boost资源。 也就是说 Node B不会给当前 UE使用 E-DPCCH power boost 特性进行信道估计。 此时， 即使 UE具有了 E-DPCCH power boost能力也 无法使用该特性， UE和 Node B仍使用 DPCCH进行信道估计， 导致高速 数据传输时仍存在信道估计准确度低， 误码率高的问题。
因此， 需要使 RNC可以明确获知 Node B是否具有 E-DPCCH power boost的能力， 以便为 Node B和 UE配置最优的无线资源。
如附图 1所示， 本发明的第一实施例提供了一种资源配置的方法， 该 方法包括：
步骤 101 , 获取 Node B的能力信息， 该能力信息中包括 Node B是否 具有 E-DPCCH power boost能力；
步骤 102, 获取 UE 的能力信息， 该能力信息中包括 UE 是否具有 E-DPCCH power boost能力；
步骤 103 , 在 UE和 Node B均具有 E-DPCCH Power boost能力时， 通 知该 Node B为当前 UE配置采用信道功率抬升能力进行信道估计的资源。 本实施例通过 RNC获取 Node B的能力信息以及 UE的能力信息， 并 根据上述获取的能力信息， 为当前 UE配置 Node B对于信道估计最优的 资源， 从而使得在 UE和 Node B均具有信道功率抬升能力时， Node B可 以采用信道功率抬升能力进行信道估计， 实现信道估计准确度的提高， 同 时也能降低高速数据传输的误码率。
下面结合附图 2具体描述本发明的第二实施例。 本发明的第二实施例 也提供了一种资源配置的方法， 该方法包括：
步骤 201 , RNC与 Node B同步 Node B的配置和能力信息。
在步骤 201中， RNC同步 Node B的配置和能力信息可以通过资源审 计过程， 也可以通过资源状态指示过程， 或者是两者的结合。
当通过资源审计过程完成 RNC与 Node B同步 Node B的配置和能力 信息时， RNC向 Node B发送资源审计请求启动资源审计过程。 在该过程 中， RNC通过 Node B发送的资源审计响应消息获知 Node B的配置情况 和能力信息等。 通过该过程， RNC可以完成 Node B配置情况和逻辑资源 状态的同步。
为了使 RNC可以明确获知 Node B是否具有 E-DPCCH power boost的 能力， Node B 在资源审计响应消息中， 携带一个信息单元 （Information Element, IE ) 用于指示该 Node B具有 E-DPCCH power boost能力或者不 具有该能力。
因此， RNC可以通过资源审计响应消息中携带的指示 Node B是否具 有 E-DPCCH power boost 能力的 IE 明确获知 Node B 是否可以使用 E-DPCCH power boost特性。
资源审计过程可以在多种情况下被触发， 不一定在下述步骤执行前才 被触发。 例如， 在 RNC启动、 倒换或者小区状况发生变化时， RNC将发 起资源审计过程。
当通过资源状态指示过程完成 RNC与 Node B同步 Node B的配置和 能力信息时， RNC接收 Node B发送的资源状态指示消息， 并根据该消息 完成 Node B的配置和能力信息的同步。 该资源状态指示消息中携带有用 于指示 Node B配置情况和逻辑资源状态的多个 IE, 其中包括了用于指示 Node B是否具有 E-DPCCH power boost能力的 IE。
RNC 通过资源状态指示消息中携带的 Node B 是否具有 E-DPCCH power boost能力的 IE, 可以明确的获知该 Node B 能否使用 E-DPCCH power boost特性进行信道估计。
Node B向 RNC发送资源状态指示消息可以在艮多情况下被触发， 而 不一定要在后续步骤执行前才进行。 例如增加 Node B的本地小区； 删除 Node B的本地小区； 本地小区的能力发生变化等情况都可能会触发 Node B向 RNC发送资源状态指示消息。
上述的资源审计过程和资源状态指示过程均可实现使 RNC 明确获知 Node B是否具有 E-DPCCH power boost能力。 同时， 两者的结合使用也可 以完成 RNC获取 Node B的能力信息的同步过程。 由于资源审计过程和资 源状态指示过程的触发条件存在不同， 所以， 两者的触发并不存在顺序上 的先后， 也不存在相互的排斥， 可以结合使用， 从而更全面的保证了， 在 UE发起 RRC连接建立时 RNC 已经准确的了解了 Node B是否可以使用 E-DPCCH power boost特性进行信道估计， 更好的保证 UE与 Node B信道 估计的准确度， 降低 UE和 Node B之间高速数据传输的误码率。
步骤 202, RNC接收 UE发送的消息， 获知 UE的能力。
当 UE发起 RRC连接时， UE会通过向 RNC发送 RRC Connection Request消息启动 RRC连接的建立过程。 在 RRC Connection Request消息 中，会携带部分该 UE的能力。在 UE向 RNC发送的 RRC Connection Setup Complete消息中， 会携带 RRC Connection Request消息中未携带的全部 UE的能力。 通过接收上述两条消息， RNC可以获知 UE全部的能力。
RNC通过上述两条消息获知的 UE的全部的能力中， 包括了 UE是否 具有 E-DPCCH power boost能力。 因此， RNC可以通过 RRC连接建立过 程， 明确获知 UE是否具有 E-DPCCH power boost能力。
可以看到， 步骤 201和步骤 202执行顺序没有先后。
步骤 203 , RNC根据 UE的能力， 为 UE配置 Node B的资源。
在 RNC接收到 UE发送的 RRC Connection Request消息后， RNC会 居该消息中携带的 UE的部分能力， 通知 Node B为 UE配置 Node B上 的资源 , 即 RL的建立。 并且， 在 RNC接收到 UE发送的 RRC Connection Setup Complete消息，获知了 UE的全部能力后，会根据 UE全部的能力重 新通知 Node B对 Node B的资源进行重新配置， 即 RL重新配置。 经过步骤 201 , RNC明确的获知 Node B是否具有 E-DPCCH power boost能力；经过步骤 202, RNC明确的获知 UE是否具有 E-DPCCH power boost能力。 因此， 在步骤 203中， RNC通过 RL建立和 RL重配过程， 可 以为 UE 最优的配置 Node B 的资源。 例如， 在 Node B 和 UE 均具有 E-DPCCH power boost能力时， RNC可以通过 RL建立过程和 RL重配过 程，通知 Node B进行资源配置给当前 UE使用 E-DPCCH power boost特性 进行信道估计， 从而提高信道估计准确度。
通过本实施例的上述步骤， RNC 可以明确的获知 Node B 是否具有 E-DPCCH power boost能力，从而在 UE和 Node B均具有 E-DPCCH power boost能力时， 为当前 UE配置 Node B使用 E-DPCCH power boost特性进 行信道估计。 根据本实施例， 在 RNC配置 Node B使用 E-DPCCH power boost特性进行信道估计时， 可以提高 UE和 Node B信道估计的准确度， 从而确保 UE和 Node B之间高速数据传输的正确率， 提高吞吐量。
此外， RNC配置完 Node B的资源后， 还可以进一步对 UE处的资源 进行配置， 例如通过无线承载 （Radio Bearer, RB ) 建立或者 RB重新配 置过程对 UE处的资源进行配置， 以达到 UE与 Node B资源配置的一致。
下面结合附图 3具体描述本发明的第三实施例。 本发明第三实施例提 供了一种在 UE移动过程中资源配置的方法， 该方法包括：
步骤 301 , 漂移 RNC ( Drift RNC, DRNC )与 Node B同步 Node B的 配置和能力信息。
DRNC通过资源审计过程或者资源状态指示过程， 或者是两者的结合 与 Node B同步 Node B的配置和能力信息， 从而获知 Node B是否具有 E-DPCCH power boost能力， 其具体实现参照本发明第二实施例中的步骤 201。
步骤 302, 服务 RNC ( Serving RNC, SRNC )接收 UE发送的消息， 获知 UE的能力。 UE通过 RRC连接建立过程，会向 SRNC上^艮其全部能力。据此， SRNC 可以明确获知 UE是否具有 E-DPCCH power boost能力。 具体实现参照本 发明第二实施例中的步骤 202。
步骤 303 , SRNC获知 Node B的能力信息。
DRNC 可以将其通过同步过程获知的 Node B 的能力信息转发给
SRNC, 由此， SRNC能够明确获知 Node B是否具有 E-DPCCH能力。
例如， DRNC可以通过在上行信令转移指示（ Uplink Signaling Transfer Indication ) 消息中， 增加一个用于指示 Node B是否具有 E-DPCCH power boost能力的 IE来通知 SRNC该 Node B是否可以使用 E-DPCCH power boost特性进行信道估计。
例如， DRNC还可以通过在 RL响应 （ RL Response ) 消息中， 增加一 个用于指示 Node B是否具有 E-DPCCH power boost 能力的 IE来通知 SRNC该 Node B是否可以使用 E-DPCCH power boost特性进行信道估计。
DRNC还可以通过其他与 SRNC之间的交互消息向 SRNC转发 Node B 的能力信息， 并不限于上述两种方式。
步骤 304, SRNC根据当前 UE的能力， 为该 UE配置 Node B的资源。
SRNC在步骤 303中， 通过 DRNC的转发明确的获知 Node B是否具 有 E-DPCCH power boost能力。 因此， 在为 UE配置 Node B的资源时， RNC可以根据 UE是否具有 E-DPCCH power boost能力为 UE配置 Node B 是否使用 E-DPCCH power boost特性进行信道估计。 其配置的具体实现可 参照本发明第二实施例中的步骤 203。
在本实施例中， 步骤 301和步骤 302之间在执行上没有特定的先后顺 序。 因为步骤 301为 DRNC获知 Node B的能力信息， 步骤 302为 SRNC 获知 UE的能力信息， 这两个步骤分别由 DRNC和 SRNC完成， 没有特定 的关联， 所以在执行上没有特定的先后顺序。 步骤 303需要在步骤 301之 后执行， 因为 DRNC获知了 Node B的能力之后才能将 Node B的能力转 发给 SRNC。 但步骤 303与步骤 302之间没有特定的先后顺序， 因为步骤 302为 SRNC获知 UE能力， 而步骤 303为 DRNC向 SRNC转发 Node B 的能力， 两者之间不一定存在特定的关联， 所以不存在特定的执行先后顺 序。
根据本发明的第三实施例， DRNC可以通过资源审计过程、 资源状态 指示过程或者两者的结合， 明确获知 Node B是否具有 E-DPCCH power boost能力。 通过 DRNC向 SRNC转发 Node B是否具有 E-DPCCH power boost能力， SRNC可以明确获知 Node B可否使用该特性进行信道估计。 由此， SRNC明确的了解 UE和 Node B是否具有 E-DPCCH power boost 的能力。 所以， 在 UE和 Node B均具有 E-DPCCH power boost能力时， 为 该 UE配置 Node使用 E-DPCCH power boost特性进行信道估计， 从而可 以提高 UE在移动场景下信道估计的准确度， 降低此场景下高速数据传输 的误码率。
此外， RNC配置完 Node B的资源后， 还可以进一步对 UE处的资源 进行配置， 以达到 UE与 Node B资源配置的一致。
下面结合附图 4具体描述本发明的第四实施例。 第四实施例提供了一 种资源配置的方法， 该方法包括：
步骤 401 , RNC获知 UE能力信息。
UE在发起 RRC连接建立的过程中， 会向 RNC上报其全部的能力信 息，因此， RNC可以明确的获知 UE是否具有 E-DPCCH power boost能力。 具体实现可以参照本发明的第二实施例中的步骤 202。
步骤 402, RNC根据 UE的能力配置 Node B上的资源。
Node B在与 RNC同步其能力信息时，没有上报其是否具有 E-DPCCH power boost能力， 此时 RNC默认该 Node B具有 E-DPCCH power boost 能力。 因此， 在 RNC 居当前 UE的能力为该 UE配置 Node B上的资源 时，如果该 UE具有 E-DPCCH power boost能力，则 RNC会为其配置 Node B使用 E-DPCCH power boost特性进行信道估计。
因此， RNC在 RL建立或者 RL 重配的过程中， 会给 Node B 配置 E-DPCCH power boost相关参数。
步骤 403 , RNC根据 Node B的反馈重新配置 Node B上的资源。
在 Node B不具有 E-DPCCH power boost能力时， 会反馈无线链路建 立失败消息给 RNC , 并在无线链路建立失败消息中携带建立失败的原因。 如果无线链路建立失败是由于 Node B不具有 E-DPCCH power boost能力， 则该 Node B 向 RNC 反馈的失败原因中包括指示该 Node B 不具有 E-DPCCH power boost能力。
RNC在接收到 Node B反馈的失败原因后， 可以明确的获知该 Node B 不具有 E-DPCCH power boost能力， 则重新发起无线链路的建立， 并在该 建立请求中不再给 Node B配置 E-DPCCH power boost的相关参数。
在本实施例中，步骤 403不一定需要执行，如果 Node B具有 E-DPCCH power boost能力， 则无需执行步骤 403 , 因为 Node B具有该能力时， 就 可以采用该特性进行信道估计， 不会因此返回无线链路建立失败。
根据本发明第四实施例， RNC在同步过程中由于 Node B未上报是否 具有 E-DPCCH power boost能力而默认其具有该能力， 因此在 UE具有 E-DPCCH power boost能力时， 会由于 RNC默认 Node B具有 E-DPCCH power boost能力而为该 UE配置 Node B使用 E-DPCCH power boost特性 进行信道估计，从而提高信道估计的质量，降低高速数据传输时的误码率。
此外， 根据本发明的第四实施例， 在 Node B不具有 E-DPCCH power boost能力时， 虽然在同步过程中 RNC会因为 Node B没有上报其是否具 有该能力而默认 Node B具有该能力， 但是仍可以在重新配置的过程中明 确 Node B的能力， 不会造成对 Node B和对 UE的配置不一致的问题。
下面结合附图 5具体描述本发明的第五实施例。 第五实施例提供了一 种 UE在移动过程中资源配置的方法， 该方法包括： 步骤 501 , SRNC获知 UE的能力， 其具体实现可以参照本发明第三实 施例中的步骤 302。
步骤 502, SRNC根据当前 UE的能力， 为其配置 Node B的资源。 Node B与 DRNC同步 Node B的能力信息时， Node B不上报其是否具 有 E-DPCCH power boost能力， DRNC默认该 Node B具有 E-DPCCH power boost能力。
在 DRNC向 SRNC转发 Node B的能力信息时， 也不会转发 Node B 是否具有 E-DPCCH power boost能力， 此时 SRNC会默认 Node B具有 E-DPCCH power boost能力。
因此，在 SRNC为 UE配置 Node B的资源时，如果 UE具有 E-DPCCH power boost能力， 则 SRNC会为 UE配置 Node B使用 E-DPCCH power boost特性进行信道估计。 此时， 在 SRNC发给 DRNC的 RL建立或 RL 重配消息中会携带 E-DPCCH power boost相关参数，且 DRNC发给 Node B 的 RL建立或 RL重配消息中也会携带有 E-DPCCH power boost相关参数。
步骤 503 , SRNC根据 Node B的反馈重新配置 Node B的资源。
在 Node B不具有 E-DPCCH power boost能力时，如果 UE具有该能力， SRNC会因为默认 Node B具有该能力而为 UE配置 Node B使用 E-DPCCH power boost特性进行信道估计。
此时， Node B由于不具有 E-DPCCH power boost能力， 会向 DRNC 反馈 RL建立失败消息， 在该消息中携带有指示 Node B不具有该能力的 失败原因。在接收到 Node B反馈的 RL建立失败消息后， DRNC会向 SRNC 反馈 RL建立失败， 并携带失败原因指示 Node B不具有 E-DPCCH power boost能力。在 SRNC了解到 RL建立失败是由于 Node B不具有 E-DPCCH power boost能力后， SRNC重新发起 RL建立或 RL重配， 并在 RL建立或 RL重配请求中不再配置 E-DPCCH power boost相关参数。
根据本发明第五实施例， DRNC在同步过程中由于 Node B未上报是 否具有 E-DPCCH power boost能力而默认其具有该能力， 由此 SRNC也会 默认 Node B具有该能力。 因此在 UE具有 E-DPCCH power boost能力时， 会由于 SRNC默认 Node B具有 E-DPCCH power boost能力而为该 UE配 置 Node B使用 E-DPCCH power boost特性进行信道估计， 从而提高信道 估计的质量， 降低高速数据传输时的误码率。
此外， 根据本发明的第五实施例， 在 Node B不具有 E-DPCCH power boost能力时，虽然在同步过程中 DRNC会因为 Node B没有上报其是否具 有该能力而默认 Node B具有该能力 ,且 SRNC也会因此默认 Node B具有 该能力。 但是仍可以通过 Node B反馈失败原因， 由 SRNC重新配置 Node B的资源， 不会造成对 Node B和对 UE的配置不一致的问题。
结合本发明的第四实施例和第五实施例可知， 在第四实施例的 RNC 为 SRNC时，可认为第四实施例中提供的方法也可以实现第五实施例中移 动场景下资源配置的问题。 因为在第五实施例中 DRNC 并不具有决策功 能， 只是起到一个传递过程， 仍由 SRNC最终掌握 UE和 Node B的能力 信息， 并根据两者的能力信息进行资源配置。
下面结合附图 6具体描述本发明的第六实施例。 第六实施例提供了一 种资源配置的方法， 该方法包括：
步骤 601 , RNC获知 UE的能力信息， 其具体实现方式参见本发明第 二实施例中的步骤 202。
步骤 602 , RNC根据当前 UE的能力， 为该 UE配置 Node B的资源。
RNC 在与 Node B 的同步过程中， Node B 不会上报其是否具有 E-DPCCH power boost 能力。 在此情况下， RNC 默认该 Node B 具有 E-DPCCH power boost能力。
因此， 在 UE具有 E-DPCCH power boost能力时， RNC会为该 UE配 置 Node B使用 E-DPCCH power boost特性进行信道估计。
步骤 603 , Node B根据自己的能力进行资源配置。 当 Node B不具 E-DPCCH power boost能力时， 如果 UE具有该能力， RNC会因为默认 Node B具有该能力而为 Node B配置 E-DPCCH power boost相关参数。 此时， Node B会因为自己不具有该能力而采用 DPCCH 进行信道估计。
在本实施例中提供的资源配置方法也可以应用在移动场景下。 在移动 场景中时，本实施例中的 RNC为 SRNC, SRNC通过 DRNC转发获取 Node B的能力信息， 且在未转发 Node B是否具有 E-DPCCH power boost能力 时，默认 Node B具有该能力。因此， SRNC在 UE具有 E-DPCCH power boost 能力时， 会为 Node B配置 E-DPCCH power boost相关参数。 Node B会根 据自身能力， 决定是否采用 E-DPCCH power boost特性进行信道估计。
根据本发明第六实施例， RNC 会在 Node B 未上报其是否具有 E-DPCCH power boost能力时， 默认 Node B具有该能力， 并在 UE具有 E-DPCCH power boost能力的情况下， 为 Node B配置 E-DPCCH power boost相关参数。 因此， 在 UE和 Node B均具有 E-DPCCH power boost能 力时， RNC可以通过资源配置使得 UE和 Node B可以采用该特性进行信 道分析， 提高信道分析准确度， 降低高速数据传输的误码率。
下面结合附图 7具体描述本发明的第七实施例。 第七实施例提供了一 种 RNC710, 该 RNC710包括：
接收模块 711 , 用于接收 Node B720和 UE730上报的能力信息， 其中 Node B720上报的能力信息中包括指示 Node B720是否具有信道功率抬升 能力的 IE;
通知模块 712,如果 UE730和 Node B720均具有信道功率抬升的能力 , 用于通知 Node B720为 UE730配置采用信道功率抬升能力进行信道估计 的资源。
接收模块 711接收 Node B720发送的资源审计响应消息或者是资源状 态指示消息，上述消息中携带着指示 Node B720是否具有 E-DPCCH power boost能力的 IE。接收模块 711还可以用于接收其他 RNC转发的指示 Node B720能力的 IE。由此，可以获知 Node B720是否具有 E-DPCCH power boost 能力。
接收模块 711还可以接收 UE730发送的 RRC连接请求或者 RRC连接 建立完成消息， 上述消息中携带着 UE730 全部的能力。 由此， 可以获知 UE730是否具有 E-DPCCH power boost能力。
通知模块 712在 UE730和 Node B720均具有 E-DPCCH power boost 能力时， 向 Node B720发送配置 E-DPCCH power boost的通知。
此外， 通知模块 712还可以用于向 UE730发送资源配置的相关参数， 即通知 UE730配置相应的资源。
本发明的第七实施例提供的 RNC在 UE处于移动或者非移动的场景 中， 均可以通过 Node B 发送的能力信息明确获知 Node B 是否具有 E-DPCCH power boost能力，从而在 UE具有该能力且 Node B也具有该能 力时， 为 UE配置 Node B采用 E-DPCCH power boost特性进行信道估计， 从而提高信道估计的准确度， 降低高速数据传输的误码率。
下面结合附图 7具体描述本发明的第八实施例。 第八实施例提供了一 种 Node B720, 该 Node B720包括：
接收模块 721 , 用于接收 RNC发送的配置 Node B信道估计资源的相 关参数；

当接收模块 721接收到 RNC710发送的资源审计请求消息时， 处理模 块 723根据 Node B720是否具有 E-DPCCH power boost能力， 在资源审计 响应消息中加入指示 Node B720是否具有 E-DPCCH power boost能力的 IE, 并通过发送模块 722发送该资源审计响应消息。
发送模块 722还可以用于将 Node B720的能力信息发给其他 RNC,再 由该 RNC转发 Node B720的能力信息给 RNC710。
处理模块 723还用于根据 Node B720是否具有 E-DPCCH power boost 能力，在用于同步 Node B资源的资源状态指示消息中加入指示 Node B720 是否具有 E-DPCCH power boost能力的 IE,并通过发送模块 722发送该资 源状态指示消息。
处理模块 723还用于根据接收模块 721接收到的 RNC710发送的配置 参数，配置 Node B720的资源。例如在接收模块 721接收到配置 E-DPCCH power boost相关参数时， 处理模块 723配置 Node B720采用 E-DPCCH power boost特性进行信道估计。
本发明的第八实施例提供的 Node B可以在指示 RNC其能力信息时， 明确指示其是否具有 E-DPCCH power boost能力， 从而使得 RNC明确的 了解该 Node B是否能够采用 E-DPCCH power boost特性进行信道估计。 因此， RNC可以在 UE和 Node B均具有 E-DPCCH power boost能力时， 为 UE配置 Node B采用 E-DPCCH power boost特性进行信道估计，提高信 道估计的准确度， 降低高速数据传输的误码率。
下面参照本发明的第七实施例， 具体描述本发明的第九实施例。 参照 附图 8, 第九实施例提供了另一种 RNC, 该 RNC包括：
接收模块 801 , 用于接收 Node B和 UE上报的能力信息；

UE和 Node B的能力， 通知 Node B为 UE配置采用信道抬升能力进行信 道估计或者采用专用物理控制信道进行信道估计。
接收模块 801接收 Node B发送的资源审计响应消息或资源状态指示 消息， 或者是其他 RNC转发的 Node B的能力信息， 上述消息中未携带有 指示 Node B是否具有 E-DPCCH power boost能力的 IE。 通知模块 802用 于在上述消息中未携带指示 Node B是否具有 E-DPCCH power boost能力 的 IE时， 默认 Node 具有该能力， 并通知 Node B为 UE配置采用信道抬 升能力进行信道估计的资源。
通知模块 802在接收模块 801接收到的 UE的能力信息中包括有指示
UE具有 E-DPCCH power boost能力的信息时， 通知 Node B为 UE配置采 用信道抬升能力进行信道估计的资源。
此外， 接收模块 801还用于接收 Node B发送的 RL建立失败的反馈； 且通知模块 802用于根据该反馈中包含的指示 Node B不具有 E-DPCCH power boost能力的失败信息，通知模块发送 RL建立或者重配的请求消息， 且在上述请求消息中不含有配置 E-DPCCH power boost的相关参数， 即通 知 Node B为 UE配置采用专用物理控制信道进行信道估计的资源。
本发明的第九实施例提供的 RNC , 在 Node B上报的能力信息中不含 有是否具有 E-DPCCH power boost能力时， 可以默认该 Node B具有此能 力。 因此， 包括 UE在移动或者非移动的场景下， 只要 UE具有 E-DPCCH power boost能力， RNC就可以为 UE配置 Node B采用 E-DPCCH power boost 特性进行信道估计， 从而提高信道估计的准确度， 降低高速数据传 输的误码率。
此外， 在 Node B不具有 E-DPCCH power boost能力时， 第九实施例 提供的 RNC可以通过 Node B反馈的失败原因，重新进行 RL建立或者 RL 重配， 并不再配置 Node B采用 E-DPCCH power boost特性进行信道估计， 从而保证了 Node B和 UE资源配置的一致。

发送模块 902还可以用于向其他 RNC发送本 Node B的能力信息， 接 收到能力信息的 RNC可以转发该能力信息。
本发明的第十实施例提供的 Node B可以在该 Node B具有 E-DPCCH power boost能力， 且接收到 RNC发送的配置 E-DPCCH power boost相关 参数时，为 UE配置 Node B采用 E-DPCCH power boost特性进行信道估计， 提高信道估计的准确度， 降低高速数据传输的误码率。 或者在该 Node B 不具有 E-DPCCH power boost能力， 且接收到 RNC发送的配置 E-DPCCH power boost相关参数时， 反馈 RL建立失败的原因为该 Node B 不具有
E-DPCCH power boost 能力， 从而使 RNC 明确获知该 Node B 不具有
E-DPCCH power boost能力，在重新配置时， 不再为该 Node B配置相应的 参数， 从而保证 UE与 Node B资源配置的一致性。
下面参照本发明的第八实施例， 具体描述本发明的第十一实施例。 参 照附图 10, 第十一实施例提供了另一种 Node B, 该 Node B包括：

此外，第十二实施例提供的系统还可以在 Node B720不具有 E-DPCCH power boost能力， 且接收到 RNC710发送的配置 E-DPCCH power boost 相关参数时， 配置 Node B720不采用 E-DPCCH power boost特性进行信道 估计， 从而使无线链路可以成功建立。
