    摘要： Methods and apparatus are provided to support HARQ in a communication system adopting cross-carrier scheduling. A second cell is scheduled at a first cell. Data, transmitted by a terminal, at a subframe of the second cell is received. A subframe, in the first cell, is determined for transmitting a HARQ acknowledgement corresponding to the data, and a subframe, in the first cell, is determined carrying scheduling information of the second cell. It is determined whether the subframe for transmitting the HARQ acknowledgement and the subframe carrying scheduling information of the second cell are the same. When the subframe for transmitting the HARQ acknowledgement and the subframe carrying the scheduling information are not the same, the subframe for transmitting the HARQ acknowledgement and the subframe carrying the scheduling information are matched to each other.
