} 步骤 S404, 终端 M成功接收主载频上的控制信令后, 首先确定携带部 分控制信令描述信息的辅助载频, 然后通过部分控制信令描述信息确定辅助 载频上部分控制信令是否发生变化, 最后解码部分控制信令发生变化的辅助 载频上的部分控制信令。 在该实施例中, 采用只解码辅助载频上与终端相关的控制信令, 相比于 现有技术, 克服了终端每次都解码所有可用载频上的控制信令会增加终端的 功耗问题, 减小了终端的功耗, 延长了终端的待机时间, 提高了系统的效率。 图 5是才艮据本发明实施例二的系统帧结构的示意图,图 5描述了本发明 提出的方法在采用时分双工( Time Division Duplexing )模式的无线通信系统 中的另一个具体实施例。 如图 5所示, 包括三个载频 RF1、 RF2和 RF3 , 无 线帧长为 5ms , 每帧包含前缀(preamble ), 控制信道等内容, 其中 RF1、 RF2 和 RF3控制信道在相同的时间段上发送, 支设对于能够同时在载频 RF 1、 载 频 RF2和载频 RF3上工作的终端 M来说, 载频 RF1是主载频, 载频 RF2、 载频 RF3是辅助载频, 以下结合图 6来详细描述本实施例的信令指示方法。 图 6 是根据本发明实施例二的多载频通信系统中的信令指示方法的详 细处理流程图, 如图 6所示,, 具体过程如下所示 (步骤 S602—步骤 S608 ): 步骤 S602,基站在终端 M的主载频 RF1上通过下行信道发送控制信令 给终端 M; 步骤 S604, 终端 M成功接收主载频控制信令后, 通过解码 "辅助载频 指示 BITMAP" , 确定携带部分控制信令描述信息的辅助载频信息。 在本实 施例中, £设 RF2和 RF3上都有和终端 M相关的部分控制信令, 则 "辅助 载频指示 BITMAP" 为 "11"。 如果只有 RF2上有和终端 M相关的部分控制 信令, 贝l "辅助载频指示 BITMAP" 表示为 "01" , 如果只有 RF3上有和终 端 M相关的部分控制信令, 则 "辅助载频指示 BITMAP" 表示为 " 10" , 如 果 RF2、 RF3 上都没有和终端 M相关的部分控制信令, 则 "辅助载频指示 BITMAP" 表示为 "00" ; 步骤 S606, 终端 M确定携带部分控制信令描述信息的辅助载频后, 在 主载频的控制信令中, 通过比较不同类型控制信令的描述信息的 Counter值 是否发生改变,确定终端 M在相应辅助载频上的部分控制信令信息是否发生 改变; 如图 5所示, 本实施例中, 叚设终端 M在辅助载频 RF3上部分控制 信令没有发生变化 (如图 5中的虚线矩形块所示), 则 Counter维持原始值不 变, 例如 Counter— 1 = 1 ( Counter— 1 的原始值为 1 ); 而在辅助载频 RF2上部 分后续控制信令发生了变化(如图 5中的实线矩形块所示),则相应的 Counter 值发生改变, 例如 Counter— 1=2 ( Counter— 1 的原始值为 1 )。 因此, 终端 M 在主载频上通过比较某个辅助载频上前后两个时刻的 Counter值#尤可以 道 需要去解码哪类的控制信令(解码发生变化的控制信令), 而不用全部解码所 有辅助载频控制信令, 从而减小终端的功耗, 延长终端的待机时间, 提高系 统效率; 步骤 S608 , 终端 M通过解码主载频上发生变化的控制信令在辅助载频 上位置信息比特 "Address" , 获得部分控制信令在辅助载频上的位置信息, 进而在辅助载频上解码相应的控制信令。 方法实施例三 才艮据本发明实施例, 提供了一种多载频通信系统中的信令发送方法。 在根据本发明实施例的多载频通信系统中的信令发送方法中,基站在终 端对应的主载频上发送控制信令, 其中, 控制信令中携带有指示信息, 指示 信息用于指示需要解码的辅助载频的控制信令在主载频上的位置。 才艮据本发明实施例, 还提供了一种多载频通信系统中的信令接收方法。 才艮据本发明实施例的多载频通信系统中的信令接收方法包括以下处理: 终端接收基站在终端的主载频上发送的控制信令, 其中, 控制信令中携带有 指示信息, 指示信息用于指示需要解码的辅助载频的部分控制信令在主载频 上的位置; 终端获取指示信息, 并才艮据指示信息确定辅助载频上与终端相关 的部分控制信令在主载频上的位置。 结合上述多载频通信系统中的信令发送及接收方法,以下结合附图来描 述本发明实施例给出的多载频通信系统中的信令指示方法。 图 7 是才艮据本发明实施例三的多载频通信系统中的信令指示方法的流 程图, 该方法是在多载频无线通信系统中, 具有在多个载频下同时工作能力 的终端 M获得其在多个载频上部分控制信令情况的方法, 支设终端 M 已知 这些载频中哪些载频对自己来说是主载频(终端 M需要解码这些载频上的控 制信令以获得自己在所有载频上的相关控制信令情况),哪些载频对自己来说 是辅助载频 (终端 M不需要解码这些载频上的控制信令), 如图 7所示, 具 体步骤如下所示 (步骤 S702—步骤 S704 ): 步骤 S702, 基站在终端 M的主载频上通过下行信道发送控制信令给终 端 M, 控制信令至少包含指示终端 M在部分辅助载频上的部分控制信令在 主载频上存放的位置信息。 其中, 主载频上发送的控制信令至少包括如表 3所示的信令格式: 表 3、 控制信令格式
