Abstract  Abstract

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.
