实施例一
图 1为本发明实施例提供的一种功率控制方法示意图。 如图 1所示, 该方法包括以下歩骤:
101、 基站生成指示信息, 所述指示信息用于指示用户设备 UE的物理上 行共享信道 PUSCH的功率纠正量 的状态和物理上行控制信道 PUCCH的 功率纠正量 g(0的状态。
在本实施例中, 基站生成一个指示信息。 其中, 指示信息可以指示 UE 配置 PUSCH的功率纠正量 的状态和物理上行控制信道 PUCCH的功率纠 正量 g(0的状态。
可选地, 基站可以生成包括第一标识码和第二标识码的指示信息。其中, 第一标识码用于指示 /(0的状态, 而第二标识码用于指示 的状态。 例如, 第一标识码和第二标识码分别为一个比特 (bit)。每个 bit位的取值可以为" 1 ", 也可以为 "0"。 其中 " 1 "用于表示启用, "0"用于表示禁用。 表 1为本实 施例提供的一种指示信息的取值范围。
表 1
Figure imgf000006_0001
在表 1中, "00"表示/ (0和 g(o的状态为禁用; "o '表示/ (0的状态 为禁用, g(o的状态为启用; " 10"表示/ ο的状态为启用, g(0的状态为禁 用; " 11 "表示/ (0和 g(0的状态为启用。 上述表 1仅为示例, 本领域技术人 员应该知道, 该示例不能作为限制本发明的条件。
102、 所述基站向用户设备 UE发送所述指示信息, 以使所述 UE根据所 述指示信息配置所述 的状态和所述 g(o的状态, 根据配置后的所述 和 所述 g(0对所述 UE的发送功率进行控制。
基站将歩骤 101中生成的指示信息发送给 UE。可选地, 基站可以采用单 播方式将指示信息发送给特定的 UE。 具体地, 基站可以根据 UE的标识信息 向所述标识信息所标识的 UE发送指示信息。
基站采用单播方式向 UE发送指示信息的一种可选的实现方式为: 基站可以在指示信息中携带 UE的标识信息,然后根据该 UE的标识信息 向该标识信息标识的 UE发送指示信息。 其中, UE的标识信息可以为 UE的 互联网协议( Internet Protocol, IP )地址,可以为介质访问控制( Media Access
Control , MAC ) 地址, 可以为国际移动用户识别码 (International Mobile
Subscriber Identification Number IMSI ) , 也可以为国际移动设备标识码 (International Mobile Equipment Identity, IMEI) 。
基站采用单播方式向 UE发送指示信息的另一种可选的实现方式为: 在该实现方式中, UE 的标识信息为 UE 的无线网络临时鉴定 (Radio
Network Temporary Identification, RNTI) 。 基站利用选取的 RNTI对指示信 息进行加扰,然后将加扰后指示信息通过 PDCCH下发。在 PDCCH上盲检过 程中, 加扰时选取的 RNTI所标识的 UE可以对加扰后的指示信息进行解扰, 得到指示信息。
可选地, 基站可以将指示信息携带在无线链路控制 (Radio Resource Control, RRC)信令中, 通过该 RRC信令携带将指示信息发送给 UE。 或者, 基站可以将指示信息携带在 MAC信令中发送给 UE。 具体地, 基站可以在 RRC或者 MAC信令中增加字段作为指示信息,然后发送给 UE。或者对 RRC 信令或者 MAC信令中的部分字段进行修改, 以用作指示信息。 由于在 RRC 信令和 MAC信令中携带了 UE的标识信息,所以基站可以直接将携带有指示 信息的 RRC信令或者 MAC信令发送给 UE,而不需要在指示信息中携带 UE 的标识信息。 而且, 在 UE进行网络切换时, 源基站也可以将指示信息携带 在一个消息中, 发送给目标基站。 在 UE完成切换后, 由目标基站将指示信 息再下发给 UE。 可选地, 在 UE入网或切换时, 基站可以在随机接入过程中 直接通过 Msg2消息将指示信息发送给 UE。 类似地, 可以在 Msg2消息中增 加或修改相应字段来携带指示信息。 在本实施例中, MAC信令或 RRC信令 等可用于已入网的 UE进行配置修改,而 Msg2消息可用于对 UE进行初始配 置。
可选地, 基站通过广播方式将指示信息下发给向 UE。具体地, 基站通过 广播信道(Broadcast Channel, BCH)向小区中所有 UE发送指示信息。例如, 基站可以将指示信息设定为小区级参数, 在广播消息中携带该指示信息, 然 后通过 BCH下发给小区中的所有 UE。
UE接收到基站发送的指示信息后,根据指示信息配置 f(i)和 g(0的状态。 具体地, 如果指示信息指示出 /(0和 g(0的状态均为禁用, UE将/ 0和 g(0的 状态均配置为禁用;如果指示信息指示出 /(0的状态为禁用, g(o的状态为启 用, UE将/ 0的状态配置为禁用, 将 g(0的状态均配置为启用; 如果指示信 息指示出 的状态为启用, g(o的状态为禁用, UE将 /(0的状态配置为启 用, 将 的状态均配置为禁用; 如果指示信息指示出 和 g(0的状态均为 启用, UE将/ 0和 g(0的状态均配置为启用。
在 UE对/ (0和 g(0的状态配置完后, UE根据配置后的 /(0和 g(0对 UE 的发送功率进行控制。 如果 UE将/ 0和 的状态均配置为启用, UE检 测到功控命令字后, 可以对 PUSCH和 PUCCH的发送功率进行调整。 如 果 UE将/ ο和 g(0的状态均配置为禁用, UE检测到功控命令字后, 不对 PUSCH和 PUCCH的发送功率进行调整, 此时, UE的发送功率维持在稳 定状态。 如果 UE将/ 0的状态配置为启用, 将 g(0的状态配置为禁用, UE 检测到功控命令字后, 只对 PUSCH的发送功率进行调整。 如果 UE将 /(0 的状态配置为禁用, 将 g(0的状态配置为启, UE检测到功控命令字后, 只 对 PUCCH的发送功率进行调整。
本实施例提供的功率控制方法, 基站生成指示信息, 指示信息指示 UE 物理上行共享信道 PUSCH 的功率纠正量 /(0的状态和物理上行控制信道 PUCCH的功率纠正量 g(0的状态, 并将指示信息发送给 UE, UE根据指示信 息配置 /(0和 g(0的状态,然后根据配置后的 /(0和 g(0对 UE的发送功率进行 控制。 本实施例基站可以向 UE发送指示信息, 指示 UE配置 和 g(o的状 态。 对于容易出现误检的 UE, 基站可以下发指示/ (0和 g(0状态为禁用的指 示信息,从而可以避免由于 UE对功控命令字的误检而导致 UE的发送功率与 目标值之间存在较大误差的问题, 提高 UE发送功率的准确性, 从而提高 UE 的性能。
对于不常出现误检的 UE, 基站可以向该 UE下发 /(0和 g(0中至少一个 的状态为启用的指示信息, 以调整 UE的发送功率, 从而实现了对 UE的发 送功率更加有效地控制。
实施例二
图 2为本发明实施例提供的另一种功率控制方法示意图。 如图 2所示, 该方法包括:
201、 用户设备 UE接收基站发送的指示信息, 所述指示信息用于指示所 述 UE的物理上行共享信道 PUSCH的功率纠正量 i 的状态和物理上行控制 信道 PUCCH的功率纠正量 g(0的状态。
在本实施例中, 基站生成一个指示信息。 其中, 指示信息可以指示 UE 配置 PUSCH的功率纠正量 的状态和物理上行控制信道 PUCCH的功率纠 正量 g(0的状态。
在生成指示信息后, 基站将指示信息发送给 UE。 在本实施例中, 基 站向 UE发送指示信息的过程, 可参见上述实施例中相关内容的记载, 此 处不再赘述。
202、所述 UE根据所述指示信息配置所述 的状态和所述 g(0的状态。
UE 在接收到基站发送的指示信息后, 根据指示信息配置/ 0的状态和 的状态。 其中, 指示信息可以指示出 UE如何对 /(0和 g(0的状态进行配 置。 具体地, 指示信息可以指示 UE将/ 0和 g(0的状态均配置为禁用, 或者 指示 UE将/ (0和 g(0中至少一个的状态配置为启用。
如果指示信息指示出 /(0和 g(0的状态均为禁用时, UE可以将 /(0和 ') 的状态均配置为禁用;如果指示信息指示出 /(0的状态为禁用, g(0的状态为 启用, UE将/ 0的状态配置为禁用, 将 的状态配置为启用; 如果指示信 息指示出/ 0的状态为启用, g(0的状态为禁用, UE将/ 0的状态配置为启 用, 将 g(0的状态配置为禁用; 如果指示信息指示出 ZX0和 g(0的状态均为启 用, UE将/ (0和 g(0的状态均配置为启用。
可选地, 指示信息包括第一标识码和第二标识码。 其中, 第一标识码用 于指示 /(0的状态, 而第二标识码用于指示 g(0的状态。 例如, 第一标识码和 第二标识码分别为一个 bit位。每个 bit位的取值可以为" 1 ",也可以为" 0"。 其中 " 1 "用于表示启用, "0"用于表示禁用。 本实施例提供的指示信息的 取值范围, 可参见表 1。 关于表 1中指示信息各取值的说明, 可参见上述 实施例中相关内容的记载, 此处不再赘述。
UE在接收到指示信息后, 根据第一标识码指示出的/ 0的状态, 相应地 配置/ 0的状态, 根据第二标识码指示出的 g(0的状态, 相应地配置 g«的 状态。
203、所述 UE根据配置后的所述 /(0和所述 g(0对所述 UE的发送功率进 行控制。
在 UE配置完 /(0和 g(0的状态后, UE根据配置后的 /(0和 g(0对 UE的 发送功率进行控制。 如果 UE将/ 0和 g(0的状态均配置为启用, UE检测 到功控命令字后, 可以对 PUSCH和 PUCCH的发送功率进行调整。 如果 UE 将/ 0和 g(0的状态配置为禁用, UE 检测到功控命令字后, 不会对 PUSCH和 PUCCH的发送功率进行调整, 此时, UE的发送功率维持在稳 定的状态。 如果 UE将/ 0的状态配置为启用, 将 g(0的状态配置为禁用, UE检测到功控命令字后, UE只对 PUSCH的发送功率进行调整。如果 UE 将/ 0的状态配置为禁用, 将 g(0的状态配置为启用, UE 检测到功控命令 字后, UE只对 PUCCH的发送功率进行调整。
本实施例提供的功率控制方法, UE接收基站发送的指示信息, 并根据指 示信息配置 /(0和 g(0的状态,然后根据配置后的 /(0和 g(0对 UE的发送功率 进行控制。本实施例基站可以向 UE发送指示信息,UE根据指示信息设置 /(0 和^ )的状态。对于容易出现误检的 UE, 基站可以下发指示/ (0和 g(0状态为 禁用的指示信息, 从而可以避免由于 UE 的误检而导致发送功率与目标值之 间存在较大误差的问题, 提高 UE发送功率的准确性, 从而提高 UE的性能。
对于不常出现误检的 UE, 基站可以向该 UE下发 /( )和 g(0中至少一个 的状态为启用的指示信息, 以调整 UE的发送功率, 从而实现了对 UE的发 送功率更加有效地控制。
实施例三
图 3为本发明实施例提供的一种基站的结构示意图。 如图 3所示, 该基 站包括: 生成模块 31和发送模块 32。
生成模块 31用于生成一个指示信息。 其中, 指示信息用于指示 UE配置 PUSCH的功率纠正量 的状态和物理上行控制信道 PUCCH的功率纠正量 g(0的状态。
可选地, 生成模块 31可以生成包括第一标识码和第二标识码的指示信 息。 其中, 第一标识码用于指示 /(0的状态, 而第二标识码用于指示 g(0的状 态。 例如, 第一标识码和第二标识码分别为一个比特(bit) 。 每个 bit位的取 值可以为 " 1 " , 也可以为 "0" 。 其中 " 1 "用于表示启用, "0"用于表示 禁用。 本实施例提供的指示信息的取值范围, 可参见表 1。 关于表 1中指 示信息各取值的说明, 可参见上述实施例中相关内容的记载, 此处不再赘 述。
发送模块 32与生成模块 31连接, 在生成模块 31生成指示信息后, 发送 模块 32将指示信息发送给 UE。可选地, 发送模块 32可以采用单播方式将指 示信息发送给特定的 UE。 具体地, 发送模块 32可以根据 UE的标识信息向 所述标识信息所标识的 UE发送指示信息。
可选地, 发送模块 32可以在指示信息中携带 UE的标识信息, 然后基站 根据该 UE的标识信息向该标识信息标识的 UE发送指示信息。 其中, UE的 标识信息可以为 UE的 IP地址、 MAC地址、 IMS或者 IMEI。
可选地, UE的标识信息可以为 RNTI。发送模块 32利用选取的 RNTI对 指示信息进行加扰,然后将加扰后指示信息通过 PDCCH下发。 UE在 PDCCH 上盲检过程中,用于加扰的 RNTI所标识的 UE可以对加扰指示信息进行解扰, 得到指示信息。
可选地, 发送模块 32可以将指示信息携带在 RRC信令或者 MAC信令 中发送给 UE。 具体地, 发送模块 32可以在 RRC或者 MAC信令中增加字段 作为指示信息, 然后发送给 UE。 或者对 RRC信令或者 MAC信令中的部分 字段进行修改, 以用作指示信息。 由于在 RRC信令和 MAC信令中携带了 UE的标识信息,所以发送模块 32可以直接将携带有指示信息的 RRC信令或 者 MAC信令发送给 UE,而不需要在指示信息中携带 UE的标识信息。而且, 在 UE进行网络切换时, 源基站可以将指示信息携带在一个消息中, 发送给 目标基站。 在 UE完成切换后, 由目标基站将指示信息再下发给 UE。
可选地, 发送模块 32通过广播方式将指示信息下发给向 UE。 具体地, 发送模块 32通过 BCH向小区中所有 UE发送指示信息。 例如, 发送模块 32 可以将指示信息设定为小区级参数, 在广播消息中携带该指示信息, 然后通 过 BCH下发给小区中的所有 UE。

在 UE对/ (0和 g(0的状态配置完后, UE根据配置后的 /(0和 g(0对 UE 的发送功率进行控制。 如果 UE将/ 0和 g(0的状态均配置为启用, UE检 测到功控命令字后, 可以对 PUSCH和 PUCCH的发送功率进行调整。 如 果 UE将/ 0和 g(0的状态均配置为禁用, UE检测到功控命令字后, 不对 PUSCH和 PUCCH的发送功率进行调整,UE的发送功率维持在稳定状态。 如果 UE将/ 0的状态配置为启用,将 的状态配置为禁用, UE检测到功 控命令字后, 只对 PUSCH的发送功率进行调整。 如果 UE将 /(0的状态配 置为禁用,将 g(0的状态配置为启用, UE检测到功控命令字后,只对 PUCCH 的发送功率进行调整。
