Abstract: An apparatus and a method for feeding back data receiving status, applied to a system, are provided. The method includes sequencing, by a User Equipment (UE), downlink subframes for transmitting data with respect to each Component Carrier (CC), generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing, where X≦M, wherein M is the number of downlink subframes on each CC, and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly, the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission, saves the uplink overheads occupied by the receiving status feedback information, and increases the uplink coverage area.
Abstract translation: 提供了一种用于反馈应用于系统的数据接收状态的装置和方法。 该方法包括由用户设备（UE）对用于相对于每个分量载波（CC）发送数据的下行链路子帧进行排序，根据所述结果，生成关于每个CC的第一X个下行链路子帧的接收状态反馈信息 排序，其中X≤M，其中M是每个CC上的下行链路子帧的数量，并且将针对每个CC生成的接收状态反馈信息发送到基站。 因此，由于与发送和接收反馈之间的基站不一致，UE不会误解下行链路子帧的接收状态。 这将影响混合自动重传请求（HARQ）传输，节省了接收状态反馈信息占用的上行链路开销，并增加了上行链路覆盖区域。
