Abstract:
1. A method for transmitting Hybrid Automatic Retransmit Request-Acknowledgment (HARQ-ACK) information to an eNode-B (eNB) by a User Equipment (UE), the method comprising: identifying KPCell as a number of downlink subframe(s) of a Pcell associated with an uplink subframe, and identifying KSCell as a number of downlink subframe(s) of an Scell associated with the uplink subframe; generating Discontinuous Transmission (DTX) response information for a cell, among the Pcell and the Scell, having a smaller number of downlink subframe between the Pcell and the Scell using a difference between the KPCell and the KSCell, wherein the DTX response information comprises DTX response(s), and the difference corresponds to a number of the DTX response(s); generating HARQ-ACK information comprising the generated DTX response information and response information on data received by the UE from the eNB; and transmitting the generated HARQ-ACK information to the eNB through the uplink subframe.
