Abstract: Provided are an apparatus and a method for executing an uplink hybrid automatic repeat request (HARQ) in a carrier aggregation system. The method transmits data to a base station from an uplink subframe of a second cell, and receives, from the base station, an acknowledgement/not-acknowledgement (ACK/NACK) or scheduling information for the data from a downlink subframe of a first cell, wherein if the timing relationship between the uplink subframe of the second cell and the downlink subframe of the first cell does not match the timing relationship for when the first cell is being used exclusively, then the scheduling information is received from the downlink subframe of the first cell.

Abstract: Provided are a method for determining the number of hybrid automatic repeat request (HARQ) processes in a carrier aggregated system configured with a plurality of serving cells, and an apparatus using such a method. The method receives data from a downlink subframe of a second serving cell, and transmits an ACK/NACK signal for the data from an uplink subframe of a first serving cell, wherein the first serving cell uses a first-type frame, the second serving cell uses a second-type frame, and the number of HARQ processes in the second serving cell are determined with respect to each subframe comprised in the second-type frame and on the basis of the number of downlink subframes comprised in each section comprising a set number of subframes.
