Abstract: A method for transmitting HARQ-ACK information based on transmission diversity is provided. The method includes configuring two component carriers, referred to as Cells, for a User Equipment (UE); when a base station configures the UE to transmit I-IARQ-ACK information adopting the transmission diversity technique, the base station indicates dynamically whether an other Cell is scheduled in the same subframe via a PDCCH scheduling a PDSCH of one Cell, so as to enable the UE to know the number of Cells scheduled in the same downlink subframe by the base station, and to generate HARQ-ACK information based on the number of Cells. Unnecessary spatial bundling of the HARQ-ACK information may be avoided, unnecessary downlink data retransmission is reduced and throughput of downlink data is improved.

Abstract translation: 提供了一种基于传输分集来发送HARQ-ACK信息的方法。 该方法包括为用户设备（UE）配置称为小区的两个分量载波; 当基站配置UE发送采用传输分集技术的I-IARQ-ACK信息时，基站通过PDCCH调度一个小区的PDSCH来动态地指示在同一子帧中是否调度其他小区，以便使能 UE知道由基站在相同下行链路子帧中调度的小区的数量，并且基于小区的数量生成HARQ-ACK信息。 可以避免HARQ-ACK信息的不必要的空间捆绑，减少不必要的下行链路数据重传，提高下行链路数据的吞吐量。
