Abstract:
1. A communication method of a terminal supporting carrier aggregation, the method comprising: receiving downlink data on a primary cell and a secondary cell from a base station; determining a maximum value between a first value and a second value; setting one or more of hybrid automatic repeat request acknowledgement (HARQ-ACK) for the primary cell to a discontinuous transmission (DTX) value based on the maximum value and the first value, if the first value is less than the maximum value; and setting one or more of HARQ ACK for the secondary cell to the DTX value based on the maximum value and the second value, if the second value is less than the maximum value, wherein the first value and the second value are integers greater than or equal to 0, and wherein the first value is a number of downlink sub-frame associated with a sub-frame of the primary cell, and the second value is a number of downlink sub-frame associated with the sub-frame of the secondary cell.
