METHODS FOR TRANSMITTING AND RECEIVING HYBRID AUTOMATIC RETRANSMIT REQUEST-ACKNOWLEDGMENT (HARQ-ACK) INDEX MAPPING AND UPLINK RESOURCE ALLOCATION FOR CHANNEL SELECTION TRANSMISSION IN INTER-BAND TIME DIVISION DUPLEX MODE, USER EQUIPMENT TO TRANSMIT HARQ-ACK, AND eNODE-B TO RECEIVE HARQ-ACK

摘要

Hybrid Automatic Retransmit ReQuest-Acknowledgment (HARQ-ACK) index mapping and uplink resource allocation is performed and controlled for channel selection transmission. A method for transmitting HARQ-ACK information to an eNode-B (eNB) by a User Equipment (UE) includes 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 having a smaller number of downlink subframes between the PCell and the SCell; generating HARQ-ACK information including 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.
