Description

小区配置方法、 功率控制方法、 设备及系统 技术领域
本发明涉及通信技术领域, 特别涉及一种小区配置方法、 功率控制方法、 设备及系统。 背景技术
HetNet ( Heterogeneous Network, 异构网络)是一种通过覆盖范围大的宏 小区 (英文: Macro Cell )和覆盖范围小的微小区 (英文: Small Cell )共同组 网的一种网络。 其中, 小区的覆盖范围由小区的下行发射功率而定。
在 HetNet中, UE ( User Equipment, 用户设备 )的上行发射功率仅取决于 UE本身, 但宏小区的下行发射功率大于微小区的下行发射功率, 因此, 上下 行功率平衡点是不相同的。请参考图 1 , 其示出了一种 HetNet组网下的宏小区 和微小区的结构示意图。 图中 A点是宏小区和微小区的上行功率平衡点,此时 UE发送的上行信号到宏小区和微小区的路损相同。 图中 B点是宏小区和微小 区的下行功率平衡点, B点更靠近微小区的位置, 此时 UE接收到的来自宏小 区和微小区的下行信号的信号强度相同。 一般的, B点还是服务小区切换点, B点以右, UE的服务小区是微小区; B点以左, UE的服务小区是宏小区。 B 点的附近有一个 SHO ( Soft Handover, 软切换) 区域 CD。 UE进入 SHO区域 CD后, 宏小区和微小区通常都会被 RNC列进 UE的激活集, 此时, UE会同 时收到分别来自宏小区和微小区的功率控制指令。现有的功率控制方法,包括: 若 UE收到激活集内任一个小区的 "降功率" 指令, 则 UE就响应为降功 率操作;
若 UE收到激活集内所有小区的 "升功率" 指令, UE才响应为升功率操 作。
在实现本发明的过程中, 发明人发现现有技术至少存在以下问题: 当 UE 处于 CB区域时, 宏小区是 UE的服务小区, 但是当宏小区向 UE发送 "升功 率" 指令时, 微小区经常会向 UE发送 "降功率" 指令, 使得宏小区对 UE的 功率控制无法满足宏小区对 UE的实际上行发射功率需求, 造成 UE无法正常 反馈数据接收正确与否的信号给宏小区, 影响数据的正常传输。 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 实施方式作进一步地详细描述。
申请人在研究过程中发现, RNC ( Radio Network Controller , 无线网络控 制器)会在宏小区和微小区中为每个 UE配置相同大小的基准 UL SIR ( Uplink Signal to Interference Ratio, 上行信号干扰比 )值, 宏小区和微小区都通过与该 UE对应的相同大小的基准 UL SIR值来对 UE进行功率控制, 当 UE实际的 UL SIR值大于基准 UL SIR值, 则小区向 UE发送 "降功率" 指令; 当 UE实 际的 UL SIR值小于基准 UL SIR值, 则小区向 UE发送 "升功率" 指令。 由于 UE发送的上行信号到达微小区时的路损小于到达宏小区的路损, 所以 小区 有更大的可能发送 "降功率" 指令给 UE。 如果 UE当前的服务小区是宏小区, 比如 UE处于 CB区域, UE的发射功率被微小区调低之后,很可能无法满足宏 小区对 UE发送上行信号时的功率需求, 此时, 即便宏小区向 UE发送 "升功 率"指令, UE也不会响应升功率操作 (因为微小区发送的是 "降功率"指令), 导致宏小区对 UE的功率控制无法满足实际需求。具体地讲,在数据传输 HARQ ( Hybrid Automatic Repeat Request , 混合自动重传请求)过程中, 宏小区通过 下行信号向 UE发送数据之后, UE需要通过上行信号通知宏小区有关数据接 收是否正确的相关反馈信息, 如果 UE的上行发射功率太小, 导致宏小区无法 接收到该反馈信息, 会严重影响宏小区的正常数据传输过程。 比如, 宏小区向 UE发送一个数据块之后, 一直无法接收到 UE通过上行信号反馈的有关该数 据块已经被正确接收的 ACK确认信息, 导致宏小区会多次重传该数据块给 UE。
为此, 本发明实施例提供了两种不同的方法来解决上述问题。 为了先对第 一种方法进行详细阐述, 请首先参考如下实施例:
请参考图 2, 其示出了本发明一个实施例中提供的功率控制方法的方法流 程图。 该功率控制方法主要用于一个 UE的激活集中同时包含第一小区和第二 小区时的功率控制。 本实施例主要以第一小区为宏小区, 第二小区为微小区进 行举例说明。 该功率控制方法, 包括:
步骤 202, RNC向第二小区发送针对一个 UE的预定指令;
当 UE的激活集中同时包含第一小区和第二小区时, UE会同时收到分别 来自第一小区和第二小区的功率控制指令。 为了使得第一小区的功率控制占主 导地位, RNC可以向第二小区发送针对该 UE的预定指令。
步骤 204, 第二小区接收到预定指令之后, 只向该 UE发送升功率指令。 第二小区接收 RNC发送的针对该 UE的预定指令。
第二小区在接收到该预定指令之后, 只向该 UE发送升功率指令, 而不可 以向该 UE发送降功率指令。 此时, 如果第一小区向该 UE发送升功率指令, 则 UE响应升功率操作; 如果第一小区向该 UE发送降功率指令, 则 UE响应 降功率操作。 显然, 此时第一小区的功率控制将占主导地位, UE 的上行发射 功率将会得到保证。 升功率指令具体可以是 TPC ( Transmit Power Control, 发射功率控制) UP 指令; 降功率指令具体可以是 TPC DOWN指令。
综上所述, 本实施例提供的功率控制方法, 通过发送预定指令让第二小区 只向 UE发送升功率指令; 解决了在 UE处于软切换区域且服务小区是第一小 区时, 第一小区对 UE的功率控制无法满足实际需求的问题; 达到了增强第一 小区对 UE的功率控制, 使得 UE的上行发射功率能够满足第一小区的需求的 效果。
需要补充说明的是, 上述步骤 202可以单独实现成为一个小区配置方法; 上述步骤 204也可以单独实现成为一个功率控制方法。 另外, 对于第一小区是 微小区, 或者第二小区是宏小区的实施例, 为本领域技术人员所易于思及的, 不再赘述。
请参考图 3, 其示出了本发明另一实施例中提供的功率控制方法的方法流 程图。 该功率控制方法主要用于一个 UE的激活集中同时包含第一小区和第二 小区时的功率控制。 本实施例主要以第一小区为宏小区, 第二小区为微小区进 行举例说明。 该功率控制方法, 包括:
步骤 302, RNC检测 UE是否符合第一预定条件, 第一预定条件包括 UE 位于软切换区域, 且 UE的服务小区为第一小区;
RNC可以只在 UE符合第一预定条件时, 才使第二小区进入只向 UE发送 升功率指令的 "特殊模式"。 该第一预定条件可以包括: UE位于软切换区域, 且 UE的服务小区为第一小区, 也即类似于 UE处于图 1中的 CB区域时的场 景。 当然,该第一预定条件也可以还包括其它条件, 比如第一预定条件可以是: UE位于软切换区域, 且 UE的服务小区为第一小区, 且第一小区的下行发射 功率减去第二小区的下行发射功率得到的差值大于预定阈值。 本实施例中仅以 预定条件包括 UE位于软切换区域, 且 UE的服务小区为第一小区进行举例说 明。
RNC可以根据内部预先存储的信息和 UE实时上报的信息, 来进行 UE是 否符合预定条件的判断过程。
步骤 304, 若 RNC检测到 UE符合第一预定条件, 则 RNC向第二小区发 送针对该 UE的预定指令;
若 RNC检测到 UE符合预定条件, 则 RNC向第二小区发送针对该 UE的 预定指令。 该预定指令可以是包含有指定值的 UL SIR信令, UL SIR信令是现有的一 种 IE ( Information Element, 信元 )信令, 用于向小区配置基准 UL SIR值。 已 经定义的取值范围为(-82, 173 ), RNC和第二小区可以事先约定一个指定值, 当 UL SIR信令中的取值为该指定值时, 该 UL SIR信令就是预定指令。
指定值可以是 UL SIR信令的取值范围之外的值, 比如 200, 此时, 需要 扩展现有 UL SIR信令的取值范围; 当然,指定值也可以是 UL SIR信令的取值 范围内指定的一个值, 比如 170。 再者, 指定值也可以是一个预定字符, 而不 是一个数值, 只要 RNC和第二小区事先进行约定即可。
作为另一种实现方式, 预定指令也可以采用一个新增的信元信令来实现。 步骤 306, 第二小区接收到预定指令之后, 只向该 UE发送升功率指令; 第二小区接收 RNC发送的针对该 UE的预定指令。
第二小区在接收到该预定指令之后, 只向该 UE发送升功率指令, 而不可 以向该 UE发送降功率指令。 此时, 如果第一小区向该 UE发送升功率指令, 则 UE响应升功率操作; 如果第一小区向该 UE发送降功率指令, 则 UE响应 降功率操作。 显然, 此时第一小区的功率控制将占主导地位, UE 的上行发射 功率将会得到保证。
升功率指令具体可以是 TPC ( Transmit Power Control, 发射功率控制) UP指令; 降功率指令具体可以是 TPC DOWN指令。
步骤 308, RNC检测 UE是否符合第二预定条件;
易于思及的, RNC还可以在 UE符合第二预定条件时,使微小区退出只向 UE发送升功率指令的 "特殊模式"。 该第二预定条件包括: UE离开软切换区 域; 或者 UE的服务小区为第二小区; 或者, UE当前不使用下行数据传输的 业务等等。 所以在步骤 306之后, RNC还可以继续检测 UE是否符合第二预定 条件。
步骤 310, 若 RNC检测到 UE符合第二预定条件, 则向第二小区发送针对 该 UE的恢复指令;
若 RNC检测到 UE符合第二预定条件,则向第二小区发送针对该 UE的恢 复指令。
恢复指令可以是包含有正常值的 UL SIR信令,正常值是指在 UL SIR信令 的取值范围内除指定值之外的其它值, 比如当指定值为 170时, 取值为 160的 UL SIR信令就是恢复指令。 作为另一种实现方式, 恢复指令也可以采用一个新增的信元信令来实现。 步骤 312, 第二小区接收到恢复指令之后, 按照正常模式向 UE发送升功 率指令或者降功率指令。
第二小区接收 RNC发送的针对该 UE的恢复指令。
第二小区接收到恢复指令之后, 按照正常模式向 UE发送升功率指令或者 降功率指令。 也即, 第二小区通过 UL SIR信令可以获知 RNC配置的与该 UE 对应的基准 UL SIR值, 当 UE实际的 UL SIR值大于基准 UL SIR值时, 第二 小区向 UE发送 "降功率" 指令; 当 UE实际的 UL SIR值小于基准 UL SIR值 时, 第二小区向 UE发送 "升功率" 指令。
综上所述, 本实施例提供的功率控制方法, 通过发送预定指令让第二小区 只向 UE发送升功率指令; 解决了在 UE处于软切换区域且服务小区是第一小 区时, 第一小区对 UE的功率控制无法满足实际需求的问题; 达到了增强第一 小区对 UE的功率控制, 使得 UE的上行发射功率能够满足第一小区的需求的 效果。 另外, 通过判断 UE是否符合第一预定条件或第二预定条件, 然后选择 性地让第二小区进入或者退出只向 UE发送升功率指令的 "特殊模式", 使得 本实施例提供的功率控制方法可以更好地融入现有的通信系统中进行使用。
需要补充说明的是, 上述步骤 302、 步骤 304、 步骤 308和步骤 310可以 单独实现成为一个小区配置方法; 上述步骤 306和步骤 312也可以单独实现成 为一个功率控制方法。 另外, 对于第一小区是微小区, 或者第二小区是宏小区 的实施例, 为本领域技术人员所易于思及的, 不再赘述。
为了对本发明实施例提供的第二种方法进行详细阐述,请继续参考如下实 施例:
请参考图 4, 其示出了本发明一个实施例中提供的功率控制方法的方法流 程图。 该功率控制方法主要用于一个 UE的激活集中同时包含第一小区和第二 小区时的功率控制。 本实施例主要以第一小区为宏小区, 第二小区为微小区进 行举例说明。 该功率控制方法, 包括:
步骤 402, RNC 向第一小区和 /或第二小区配置针对一个 UE 的基准 UL SIR, 以使得第一小区中针对该 UE的第一基准 UL SIR不同于第二小区中针对 该 UE的第二基准 UL SIR;
现有的方案中, 对于同一个 UE, RNC向第一小区和第二小区配置相同大 小的基准 UL SIR。 但在本实施例中, RNC向第一小区和第二小区配置不同大 小的基准 ULSIR。具体地讲, 为了消除 UE的上行信号发送至第一小区时的路 损与发送至第二小区时的路损不同而导致的功率控制差异, RNC向第二小区配 置的第二基准 UL SIR可以大于向第一小区配置的第一基准 UL SIR。 本步骤可 以采用如下方式实现:
RNC可以只向第一小区配置第一基准 ULSIR, 同时, RNC本次配置给第 一小区的第一基准 UL SIR不同于第二小区的当前第二基准 UL SIR, 第二小区 的当前第二基准 ULSIR可以是上一次配置的第二基准 ULSIR。 比如, RNC只 向第一小区配置第一基准 ULSIR, 且本次配置的第一基准 ULSIR小于上次配 置的第二基准 ULSIR。
RNC也可以只向第二小区配置第二基准 ULSIR, 同时, RNC本次配置给 第二小区的第二基准 ULSIR不同于第一小区的当前第一基准 ULSIR, 第一小 区的当前第一基准 ULSIR可以是上一次配置的第一基准 ULSIR。 比如, RNC 只向第二小区配置第二基准 ULSIR, 且本次配置的第二基准 ULSIR大于上次 配置的第一基准 ULSIR。
RNC也可以同时向第一小区和第二小区配置基准 ULSIR, 同时, RNC本 次配置给第一小区的第一基准 UL SIR不同于本次配置给第二小区的第二基准 ULSIR。 比如, RNC同时向第一小区和第二小区配置基准 ULSIR, 且本次配 置的第一基准 ULSIR小于本次配置的第二基准 ULSIR。
步骤 404,第一小区或者第二小区根据接收到的基准 ULSIR对 UE进行功 率控制。
第一小区和 /或第二小区接收 RNC配置的针对该 UE的基准 UL SIR, 以使 得第一小区中针对该 UE的第一基准 UL SIR不同于第二小区中针对该 UE的第 二基准 UL SIRo
此后, 第一小区和第二小区根据 RNC配置的基准 ULSIR对 UE进行功率 控制。 具体地讲:
当 UE实际的 UL SIR值大于第一基准 UL SIR时,第一小区向 UE发送"降 功率" 指令; 当 UE实际的 UL SIR值小于第一基准 UL SIR时, 第一小区向 UE发送 "升功率" 指令。
当 UE实际的 ULSIR值大于第二基准 ULSIR时,第二小区向 UE发送"降 功率" 指令; 当 UE实际的 UL SIR值小于第二基准 UL SIR时, 第二小区向 UE发送 "升功率" 指令。 综上所述, 本实施例提供的功率控制方法, 通过向第一小区和第二小区配 置不同大小的基准 UL SIR,使得第二小区在更高的阈值情况下才触发向 UE发 送升功率指令; 解决了在 UE处于软切换区域且服务小区是第一小区时, 第一 小区对 UE的功率控制无法满足实际需求的问题; 达到了增强第一小区对 UE 的功率控制,使得 UE的上行发射功率能够满足第一小区的需求的效果。 同时, 与上一实施例相比, 上一实施例中的第二小区进入 "特殊模式" 后, 只能向 UE发送升功率指令, 无法对 UE进行降功率控制, 而本实施例提供的方法, 第二小区仍然可以对 UE进行正常的功率控制, 具有更好的功率控制效果。
需要说明的是, 上述步骤 402可以单独实现成为一个小区配置方法; 上述 步骤 404和步骤 406可以单独实现成为一个功率控制方法。
当然, 本领域技术人员可以易于思及的是: 虽然本实施例中主要以 RNC 向第二小区配置的第二基准 UL SIR大于向第一小区配置的第一基准 UL SIR, 以加强第一小区对 UE的功率控制进行举例说明。 但是, 在某些场景下, RNC 向第二小区配置的第二基准 UL SIR可以小于向第一小区配置的第一基准 UL SIR, 从而弱化第一小区对 UE 的功率控制。 比如: 不论第一小区是宏小区还 是微小区, 也不论第二小区是宏小区还是微小区, 当第二小区是服务小区, 由 于路损和衰落的双重影响, 导致第一小区可以良好地接收到 UE的信号, 但是 第二小区无法良好地接收到 UE的信号的场景下, RNC向第二小区配置的第二 基准 UL SIR可以小于向第一小区配置的第一基准 UL SIR, 从而弱化第一小区 对 UE的功率控制。
由于 RNC向第一小区和 /或第二小区配置不同大小的基准 UL SIR存在两 种实施方式,为了对第一种实施方式进行更为详细地描述,请参考如下实施例: 请参考图 5, 其示出了本发明另一实施例提供的功率控制方法的方法流程 图。 该功率控制方法主要用于一个 UE的激活集中同时包含第一小区和第二小 区时的功率控制。本实施例主要以第一小区为宏小区,第二小区为微小区, RNC 通过现有的 UL SIR信令来对第一小区和第二小区配置不同大小的基准 UL SIR 进行举例说明。 该功率控制方法, 包括:
步骤 502, RNC检测 UE是否符合第一预定条件, 第一预定条件包括 UE 位于软切换区域, 且 UE的服务小区为第一小区;
作为上一实施例的优化, RNC可以只在 UE符合第一预定条件时, 才对第 一小区和第二小区配置不同的基准 UL SIR值。 该第一预定条件可以包括: UE 位于软切换区域, 且 UE的服务小区为第一小区, 也即类似于 UE处于图 1中 的 CB区域时的场景。 当然, 该第一预定条件也可以还包括其它条件, 比如第 一预定条件可以是: UE位于软切换区域, 且 UE的服务小区为第一小区, 且 第一小区的下行发射功率减去第二小区的下行发射功率得到的差值大于预定 阈值。 本实施例中仅以预定条件包括 UE位于软切换区域, 且 UE的服务小区 为第一小区进行举例说明。
RNC可以根据内部预先存储的信息和 UE实时上报的信息, 来进行 UE是 否符合第一预定条件的判断过程。
步骤 504, 若 RNC检测到 UE符合第一预定条件, 则 RNC向第一小区和 / 或第二小区发送 UL SIR信令, UL SIR信令中包括针对该 UE的基准 UL SIR;
在 RNC检测到 UE符合第一预定条件时, RNC可以对第一小区和第二小 区配置不同大小的基准 UL SIR值。 具体地讲:
RNC可以向第一'』、区发送 UL SIR信令, 该 UL SIR信令中包含有本次配 置的第一基准 UL SIR, 本次配置的第一基准 UL SIR不同于当前的第二基准 UL SIR, 当前的第二基准 UL SIR可以是本次或者上一次配置的第二基准 UL SIR。 比如, RNC已经向第二小区配置过第二基准 UL SIR, 本次可以向第一小 区配置一个小于当前第二基准 UL SIR的第一基准 UL SIR。 或者,
RNC可以向第二小区发送 UL SIR信令, 该 UL SIR信令中包含有本次配 置的第二基准 UL SIR, 本次配置的第二基准 UL SIR不同于当前的第一基准 UL SIR, 当前的第一基准 UL SIR可以是本次或者上一次配置的第一基准 UL SIR。 比如, RNC已经向第一小区配置过第一基准 UL SIR, 本次可以向第二小 区配置一个大于当前第一基准 UL SIR的第二基准 UL SIR。 或者,
RNC可以向第一小区和第二小区均发送 UL SIR信令, 发送至第一小区的 UL SIR信令中包含有本次配置的第一基准 UL SIR,发送至第二小区的 UL SIR 信令中包含有本次配置的第二基准 UL SIR, 本次配置的第一基准 UL SIR不同 于本次配置的第二基准 UL SIR。 比如, RNC是第一次向第一小区和第二小区 配置该 UE的基准 UL SIR, 本次配置的第一基准 UL SIR小于本次配置的第二 基准 UL SIR。
需要补充说明的是, RNC 在向第一小区和第二小区配置不同的基准 UL SIR之前,, 可以根据该 UE对应于第一'』、区的上行路损与该 UE对应于第二小 区的上行路损之间的差值确定第一基准 UL SIR不同于第二基准 UL SIR时的差 值, 比如, RNC可以确定第一基准 UL SIR不同于第二基准 UL SIR时的差值 的绝对值等于该 UE对应于第一小区的上行路损与该 UE对应于第二小区的上 行路损之间的差值的绝对值; 然后, RNC根据确定的差值确定向第一小区和 / 或第二小区配置针对该 UE的基准 UL SIR时所需的配置参数, 该配置参数包 括本次配置的第一基准 UL SIR和本次配置的第二基准 UL SIR中的至少一种。 在其它实施例中, RNC还可能同时考虑路损和衰落来确定第一基准 UL SIR与 第二基准 UL SIR之间的差值的大小。
由于 RNC需要向一个小区配置大于另一小区的基准 UL SIR值, 现有的 UL SIR信令的取值范围可能会无法满足使用, 此时, 可以采用扩展取值范围 之后的 UL SIR信令, 比如, 取值范围为 (-83, 210 ) 的 UL SIR信令。
步骤 506,第一小区或者第二小区根据接收到的基准 UL SIR对 UE进行功 率控制;
第一小区和 /或第二小区接收 RNC配置的针对该 UE的基准 UL SIR。具体 地讲:
若 RNC向第一小区发送了 UL SIR信令,则第一小区接收 RNC发送的 UL SIR信令, 该 UL SIR信令中包含有本次配置的第一基准 UL SIR;
第一小区将当前第一基准 UL SIR更新为本次配置的第一基准 UL SIR, 本 次配置的第一基准 UL SIR不同于当前的第二基准 UL SIR。
若 RNC向第二小区发送了 UL SIR信令,则第二小区接收 RNC发送的 UL SIR信令, 该 UL SIR信令中包含有本次配置的第二基准 UL SIR;
第二小区将当前第二基准 UL SIR更新为本次配置的第二基准 UL SIR, 本 次配置的第二基准 UL SIR不同于当前的第一基准 UL SIR。
此后, 第一小区和第二小区根据 RNC配置的基准 UL SIR对 UE进行功率 控制。 具体地讲:
当 UE实际的 UL SIR值大于第一基准 UL SIR时,第一小区向 UE发送"降 功率" 指令; 当 UE实际的 UL SIR值小于第一基准 UL SIR时, 第一小区向 UE发送 "升功率" 指令。
当 UE实际的 UL SIR值大于第二基准 UL SIR时,第二小区向 UE发送"降 功率" 指令; 当 UE实际的 UL SIR值小于第二基准 UL SIR时, 第二小区向 UE发送 "升功率" 指令。
步骤 508, RNC检测 UE是否符合第二预定条件; 易于思及的, RNC还可以在 UE符合第二预定条件时, 重新向第一小区和 第二小区配置相同大小的基准 UL SIR。 该第二预定条件包括: UE离开软切换 区域; 或者 UE的服务小区为第二小区; 或者, UE当前不使用下行数据传输 的业务等等。 所以在步骤 504之后, RNC还可以继续检测 UE是否符合第二预 定条件。
步骤 510, 若 RNC检测到 UE符合第二预定条件, 则向第一小区和第二小 区配置相同大小的基准 UL SIR;
若 RNC检测到 UE符合第二预定条件, 则向第一小区和第二小区配置相 同大小的基准 UL SIR。 该过程可以通过与步骤 504非常筒易地联想到, 不再 赘述。
步骤 512,第一小区或者第二小区根据接收到的基准 UL SIR对 UE进行功 率控制。
此后, 第一小区和第二小区可以根据相同大小的基准 UL SIR值来对 UE 进行功率控制, 具体控制细节, 与步骤 506相同, 不再赘述。
步骤 514, RNC向第二小区发送具有指定值的 UL SIR信令;
本实施例还可以结合实施例一所述的方法,也即, RNC向第二小区发送具 有指定值的 UL SIR信令, 以便使得第二小区只向 UE发送升功率指令。
指定值为 UL SIR信令的取值范围之外的值,或指定值为 UL SIR信令的取 值范围内指定的一个值, 或指定值为预定字符。
步骤 516, 第二小区在接收到具有指定值的 UL SIR信令之后, 只向 UE发 送升功率指令。
综上所述, 本发明实施例提供的功率控制方法, 通过向第一小区和第二小 区配置不同大小的基准 UL SIR, 使得第二小区在更高的阈值情况下才触发向 UE发送升功率指令; 解决了在 UE处于软切换区域且服务小区是第一小区时, 第一小区对 UE的功率控制无法满足实际需求的问题; 达到了增强第一小区对 UE的功率控制, 使得 UE的上行发射功率能够满足第一小区的需求的效果。 另外, 通过判断 UE是否符合第一预定条件和第二预定条件, 然后选择性地对 第一小区和第二小区配置相同大小或者不同大小的基准 UL SIR值, 使得本实 施例提供的功率控制方法可以更好地融入现有的通信系统中进行使用。
需要说明的是, 上述步骤 502、 步骤 504、 步骤 508、 步骤 510和步骤 514 可以单独实现成为一个小区配置方法; 上述步骤 506、 步骤 512和步骤 516可 以单独实现成为一个功率控制方法。
由于 RNC向第一小区和 /或第二小区配置不同大小的基准 UL SIR存在两 种实施方式,为了对第二种实施方式进行更为详细地描述,请参考如下实施例: 请参考图 6, 其示出了本发明再一实施例提供的功率控制方法的方法流程 图。 该功率控制方法主要用于一个 UE的激活集中同时包含第一小区和第二小 区时的功率控制。本实施例主要以第一小区为宏小区,第二小区为微小区, RNC 通过新增的信元信令来对第一小区和第二小区配置不同大小的基准 UL SIR进 行举例说明。 该功率控制方法, 包括:
步骤 602, RNC检测 UE是否符合第一预定条件, 第一预定条件包括 UE 位于软切换区域, 且 UE的服务小区为第一小区;
RNC可以只在 UE符合第一预定条件时,才对第一小区和第二小区配置不 同的基准 UL SIR值。 该第一预定条件可以包括: UE位于软切换区域, 且 UE 的服务小区为第一小区, 也即类似于 UE处于图 1中的 CB区域时的场景。 当 然, 该第一预定条件也可以还包括其它条件, 比如第一预定条件可以是: UE 位于软切换区域, 且 UE的服务小区为第一小区, 且第一小区的下行发射功率 减去第二小区的下行发射功率得到的差值大于预定阈值。本实施例中仅以预定 条件包括 UE位于软切换区域, 且 UE的服务小区为第一小区进行举例说明。
RNC可以根据内部预先存储的信息和 UE实时上报的信息, 来进行 UE是 否符合第一预定条件的判断过程。
步骤 604, 若 RNC检测到 UE符合第一预定条件, 则 RNC向第一小区或 者第二小区发送设置指令, 该设置指令中包含第一 SIR调整量和 /或第二 SIR 调整量;
在 RNC检测到 UE符合第一预定条件时, RNC可以对第一小区和第二小 区配置不同大小的基准 UL SIR值。 具体地讲:
RNC可以向第一小区发送设置指令, 该设置指令包括有第一 SIR调整量, 以便第一小区得到本次配置的第一基准 UL SIR为: 当前的第一基准 UL SIR+ 第一 SIR调整量, 第一 SIR调整量为非零的正数或者负数。 比如, RNC向第 一小区发送一个取值为负数的第一 SIR调整量, 使得第一基准 UL SIR小于第 二基准 UL SIR。 或者,
RNC也可以向第二小区发送设置指令, 该设置指令包括有第二 SIR调整 量, 以便第二小区得到本次配置的第二基准 UL SIR为: 当前的第二基准 UL SIR+第二 SIR调整量, 第二 SIR调整量为非零的正数或者负数。 比如, RNC 向第二小区发送一个取值为正数的第一 SIR调整量, 使得第二基准 UL SIR大 于第二基准 UL SIR。 或者,
RNC也可以向第一小区和第二小区均发送设置指令,发送至第一小区的设 置信令中包含有第一 SIR调整量, 以便第一小区得到本次配置的第一基准 UL SIR为: 当前的第一基准 UL SIR+/-第一 SIR调整量; 发送至第二小区的设置 信令中包含有第二 SIR调整量,以便第二小区得到本次配置的第二基准 UL SIR 为:当前的第二基准 UL SIR+/-第二 SIR调整量,且本次配置的第一基准 UL SIR 不同于本次配置的第二基准 UL SIR。
需要补充说明的是, RNC 在向第一小区和第二小区配置不同的基准 UL SIR之前, 可以根据该 UE对应于第一小区的上行路损与该 UE对应于第二小 区的上行路损之间的差值确定第一基准 UL SIR不同于第二基准 UL SIR时的差 值, 比如, RNC可以确定第一基准 UL SIR不同于第二基准 UL SIR时的差值 的绝对值等于该 UE对应于第一小区的上行路损与该 UE对应于第二小区的上 行路损之间的差值的绝对值; 然后, RNC根据确定的差值确定向第一小区和 / 或第二小区配置针对该 UE的基准 UL SIR时所需的配置参数, 该配置参数包 括第一 SIR调整量和第二 SIR调整量中的至少一种。 在其它实施例中, RNC 还可能同时考虑路损和衰落来确定第一 SIR调整量和 /或第二 SIR调整量的大 小。
设置指令可以是一个新增的信元信令。
步骤 606 ,第一小区或者第二小区根据第一 SIR调整量和 /或第二 SIR调整 量调整基准 UL SIR, 然后根据调整后的基准 UL SIR对 UE进行功率调整; 第一小区和 /或第二小区接收 RNC发送的第一 SIR调整量和 /或第二 SIR调 整量, 然后根据第一 SIR调整量和 /或第二 SIR调整量调整基准 UL SIR。 具体 地讲:
若 RNC向第一小区发送了第一 SIR调整量,第一小区接收 RNC发送的设 置指令, 该设置指令包括有第一 SIR调整量;
第一小区调整第一基准 UL SIR为: 当前的第一基准 UL SIR+第一 SIR调 整量。
若 RNC向第二小区发送了第二 SIR调整量,第二小区接收 RNC发送的设 置指令, 该设置指令包括有第二 SIR调整量; 第二小区调整第二基准 UL SIR为: 当前的第二基准 UL SIR+第二 SIR调 整量。
此后, 第一小区和第二小区根据调整后的基准 UL SIR对 UE进行功率控 制。 具体地讲:

当 UE实际的 UL SIR值大于第二基准 UL SIR时,第二小区向 UE发送"降 功率" 指令; 当 UE实际的 UL SIR值小于第二基准 UL SIR时, 第二小区向 UE发送 "升功率" 指令。
步骤 608, RNC检测 UE是否符合第二预定条件;
易于思及的, RNC还可以在 UE符合第二预定条件时, 重新向第一小区和 第二小区配置相同大小的基准 UL SIR。 该第二预定条件包括: UE离开软切换 区域; 或者 UE的服务小区为第二小区; 或者, UE当前不使用下行数据传输 的业务等等。 所以在步骤 604之后, RNC还可以继续检测 UE是否符合第二预 定条件。
步骤 610, 若 RNC检测到 UE符合第二预定条件, 则向第一小区和第二小 区配置相同大小的基准 UL SIR;
若 RNC检测到 UE符合第二预定条件, 则向第一小区和第二小区配置相 同大小的基准 UL SIR。 该过程可以通过与步骤 604非常筒易地联想到, 不再 赘述。
步骤 612,第一小区或者第二小区根据接收到的基准 UL SIR对 UE进行功 率控制。
此后, 第一小区和第二小区可以根据相同大小的基准 UL SIR值来对 UE 进行功率控制, 具体控制细节, 与步骤 606相同, 不再赘述。
步骤 614, RNC向第二小区发送特定的设置指令;
本实施例还可以结合实施例一所述的方法,也即, RNC向第二小区发送具 有指定值的设置指令, 以便使得第二小区只向 UE发送升功率指令。
指定值为预定数值或者预定字符。
步骤 616, 第二小区在接收到特定的预定指令之后, 只向 UE发送升功率 指令。 综上所述, 本发明实施例提供的功率控制方法, 通过向第一小区和第二小 区配置不同大小的基准 UL SIR, 使得第二小区在更高的阈值情况下才触发向 UE发送升功率指令; 解决了在 UE处于软切换区域且服务小区是第一小区时, 第一小区对 UE的功率控制无法满足实际需求的问题; 达到了增强第一小区对 UE的功率控制, 使得 UE的上行发射功率能够满足第一小区的需求的效果。 另外, 通过判断 UE是否符合第一预定条件和第二预定条件, 然后选择性地对 第一小区和第二小区配置相同大小或者不同大小的基准 UL SIR值, 使得本实 施例提供的功率控制方法可以更好地融入现有的通信系统中进行使用。
需要说明的是, 上述步骤 602、 步骤 604、 步骤 608、 步骤 610和步骤 614 可以单独实现成为一个小区配置方法; 上述步骤 606、 步骤 612和步骤 616可 以单独实现成为一个功率控制方法。 下述为本发明装置实施例, 其中未详尽描述地内容, 可以结合参考上述对 应的方法实施例。
请参考图 7, 其示出了本发明一个实施例提供的通信系统的结构方框图。 该通信系统可以用于一个 UE的激活集中同时包含第一小区和第二小区时的功 率控制。 该通信系统包括无线网络控制器 720和对应于第二小区的基站 740。
无线网络控制器 720, 包括: 预定发送模块 722;
