Abstract
The present application discloses a method and apparatus for a hybrid automatic repeat request (HARQ) transmission. An embodiment of the HARQ transmission method for the communication apparatus comprises: receiving configuration information related to a cross-carrier HARQ transmission from a base station, an initial transmission and a re-transmission of the HARQ transmission processable on different physical component carriers; receiving downlink control information from the base station, the downlink control information including control information for the cross-carrier HARQ transmission; and performing the cross-carrier HARQ transmission according to the configuration information and the downlink control information. By using the embodiments of the present invention, the HARQ transmission for the same data on a plurality of physical component carriers can be realized, and thus the effectiveness of the HARQ transmission is improved.
