步骤505：计算降低调制编码等级并且减少资源分配信息后的待发送数据的总功率。
步骤506：判断功率是否受限，当判断的结果为是时，返回执行步骤504至步骤506；当判断的结果为否时，执行步骤507。
这里，所述判断功率是否受限包括：判断降低调制编码等级并且减少资源分配信息后的待发送的数据的总功率是否大于所述终端的功率放大器可以支持的最大线性功率，获得判断结果；当所述判断结果为所述降低调制编码等级并且减少资源分配信息后的待发送的数据的总功率大于所述终端的功率放大器可以支持的最大线性功率时，确定功率受限；当所述判断结果为所述降低调制编码等级并且减少资源分配信息后的待发送的数据的总功率不大于所述终端的功率放大器可以支持的最大线性功率时，确定功 率不受限。
步骤507：添加数据中的控制信息，发送降低调制编码等级并且减少资源分配信息后的数据。
这里，所述终端根据本实施例的功率是否受限情况、调制编码等级以及资源分配情况填充控制信息。所述控制信息可以包括：功率受限信息、调制编码等级信息和资源分配信息；在具体应用中，所述功率受限信息可以通过图2所示的功率受限标识实现；例如当所述功率受限标识设置为“0”时，表征所述终端功率不受限；当所述功率受限标识设置为“1”时，表征所述终端功率受限；当然，可以设置为当所述功率受限标识为“0”时，表征所述终端功率受限；当所述功率受限标识设置为“1”时，表征所述终端功率不受限，具体可由所述终端和基站侧预先设定。
所述调制编码等级信息可通过图2所示的编码调制等级字段表示；具体的编码调制方式为所述编码调制等级字段中的二进制编码对应的编码调制方式；所述二进制编码与对应的调制编码等级信息可由所述终端和所述基站预先协商设定。
所述资源分配信息可通过如图2所示的资源分配信息字段实现，例如，当所述资源分配信息字段为1111时，对应所述资源分配信息为基站为所述终端分配的资源的全集，当所述资源分配信息字段为1000时，对应所述资源分配信息为基站为所述终端分配的资源的百分之X(X为小于100的整数)；其中，所述二进制编码与对应的资源分配信息可由所述终端和所述基站预先协商设定；所述资源分配信息字段的二进制编码与基站为所述终端分配的资源的百分比也可由所述终端和所述基站预先协商设定。在本实施例中，所述资源分配信息即为基站为所述终端预先配置的资源的百分之X(X为小于100的整数)，表征基站为所述终端分配的资源的子集。
