方式二: 调制编码方式携带在无线帧的信息信道中; 方式三: 该调制编码方式携带在前导序列中, 其中, 该前导序列为基站发送的用 于终端进行下行同步的序列。 对于方式三, 该调制编码方式携带在该前导序列中, 可以通过直接或者间接的方 式指示该调制编码方式。 对于直接的指示方式, 可以在前导序列中直接携带该调制编 码方式, 这种方式需要直接携带调制编码方式, 携带的比特的数量比较多, 由于前导 序列本身也需要携带同步信息,这样会造成信令承载负荷过大。对于间接的指示方式, 可以采用如下方式进行指示: 确定该前导序列的索引; 根据该前导序列的索引和该索 引的对应关系确定调制编码方式, 其中该索引的对应关系为该前导序列和该调制编码 方式的对应关系。 这种方式通过预设前导序列的索引和调制编码方式的对应关系, 携 带的比特的数量非常小, 大大降低了前导序列的信令负荷。 作为一个优选的实施方式, 控制信道的位置信息可以采用多种方式进行处理: 方式一: 由系统配置, 例如: 对所有控制信令通过上层信令进行配置, 或者按照 相关标准 (3GPP) 进行默认配置。 方式二: 该控制信道的位置信息携带在无线帧的信息信道中。 例如: 通过信息信 道进行直接或者间接的指示。 对于直接指示方法, 可以在信息信道中携带位置的信息 (时频资源位置), 例如: 控制信令所在的时隙号或者频域位置。 对于间接指示方法, 控制信令可以通过以下方 式之一指示在控制信道中的位置信息: 方式一: 控制信令在控制信道占用的时域长度信息, 其中, 时域长度信息用于指 示控制信道占用的 OFDM符号的数量或时域长度信息用于指示控制信令占用的资源 块在时域上的时间长度 TBlock的数量,其中, 该 TBlock是指资源块在时域上的长度。 方式二: 控制信道占用的时域起始位置信息和时域结束位置信息, 其中, 时域起 始位置信息和时域结束位置信息为 OFDM符号的索引信息或资源块的索引信息。 优选地, 资源块在时域上包括一个或多个 OFDM符号的长度, 在频域上包括一个 或多个子载波。 资源块是一个时频的资源, 包括在时域上 OFDM符号的长度, 和频域 上的多个子载波。 本实施例提供了一种数据处理方法, 图 2是根据本发明实施例的数据处理方法的 流程图, 如图 2所示, 该方法包括如下步骤 S202和步骤 S204。 步骤 S202: 接收无线帧的控制信道上的控制信令, 其中, 该控制信令占用的时频 资源大小相同。 步骤 S204: 对该控制信令中的一个或多个控制信令进行解码。 通过上述方法, 接收的控制信令是时频资源大小相同的, 就可以快速、 准确定位 出控制信令所在的位置, 然后对该控制信令进行解码, 克服了相关技术中对控制信令 解码时间长且准确度不高的问题, 从而可以提高数据传输的效率。 作为一个优选的实施方式,在步骤 S204包括: 获取所述一个或多个时频资源大小 相同的控制信令在该控制信道的预设位置信息; 根据该预设位置信息和时频资源大小 对一个或多个时频资源大小相同的控制信令进行解码。 即, 由于每个控制信令使用的 时频资源位置相同, 获取到控制信道的位置信息, 就相当于获取到了所有控制信令的 位置信息, 然后在这些位置上进行盲检测就可以得到对应的控制信令, 盲检测不需要 明确控制信令所采用的调制编码方式, 在保证一定的解码准确率的情况下降低系统的 信令开销。 需要说明的是, 本优选实施例在明确控制信道所采用的调制编码方式的情 况下, 也可以采用对应的解码方式进行解码, 这种方式解码的准确率比盲检测的准确 率高。 作为另一个优选实施例, 预设位置信息可以采用如下多种方式: 方式一: 占用的时频资源位置是连续分布。 方式二: 占用的时频资源位置是连续分布, 其中一个或多个时频资源大小相同的 控制信令中的第一个控制信令占用的时频资源位置根据预设规则确定。 比较优的, 方 式二中的预设规则可以根据胸膛那个配置或者通过信令传输确定。 方式三: 占用的时频资源位置由系统配置。 对于方式一, 每一个用户的所有控制信令占用的资源位置是连续分布的, 可以根 据连续分布的资源位置确定所有控制信令的位置, 该方式占用的信令负荷最小, 该方 式下的解调可以采用盲检测; 对于方式二, 与方式一相比增加了控制信令中的第一个 控制信令占用的位置可以根据预设规则确定, 这样, 由于每个控制信令所占用的时频 资源大小是相同的, 确定出第一个控制信令的位置就可以确定所有控制信令的位置, 该方式下可以采用盲检测进行解码; 对于方式三, 控制信令的占用的时频资源位置是 由系统配置, 该方式下实现了对控制信令的统一配置。 在实施时, 在方式二中, 根据位置信息和时频资源大小对一个或多个控制信令进 行盲检测包括如下步骤: 对使用预设规则确定的第一个控制信令占用的时频资源位置 上的控制信令进行解码; 判断解码得到的控制信令是否为一个用户对应的第一个控制 信令; 如果判断结果为是, 对第一个控制信令占用的时频资源位置的相邻时频资源位 置上的控制信令进行解码; 如果判断结果为否, 取消对第一个控制信令占用的时频资 源位置的相邻时频资源位置上的控制信令进行解码。 需要说明的是, 在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的 计算机系统中执行, 并且, 虽然在流程图中示出了逻辑顺序, 但是在某些情况下, 可 以以不同于此处的顺序执行所示出或描述的步骤。 在另外一个实施例中, 还提供了一种数据传输软件, 该软件用于执行上述实施例 及优选实施例中描述的技术方案。 在另外一个实施例中, 还提供了一种存储介质, 该存储介质中存储有上述数据传 输软件, 该存储介质包括但不限于: 光盘、 软盘、 硬盘、 可擦写存储器等。 本发明实施例还提供了一种数据传输装置, 该数据传输装置可以用于实现上述数 据传输方法及优选实施方式, 已经进行过说明的, 不再赘述, 下面对该传输装置中涉 及到的模块进行说明。 如以下所使用的, 术语"模块"可以实现预定功能的软件和 /或硬 件的组合。 尽管以下实施例所描述的系统和方法较佳地以软件来实现, 但是硬件, 或 者软件和硬件的组合的实现也是可能并被构想的。 图 3是根据本发明实施例的数据传输装置的结构框图, 如图 3所示, 该装置包括: 配置模块 32和传输模块 34, 下面对上述结构进行详细描述。 配置模块 32, 设置为配置无线帧的控制信道包括一个或多个占用时频资源大小相 同的控制信令;
