Abstract

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.

Claims (8)

1 .- 15 . (canceled)

16 . A method for transmitting Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK), the method comprising:

setting N pieces of HARQ-ACK to Discontinuous Transmission (DTX) for a cell, based on a difference between KPCeli and KSCell, the difference being associated with the number N, the number N being an integer greater than one;

generating the HAJZQ-ACK comprising the N pieces of HARQ-ACK set to DTX, the HARQ-ACK being responsive to data received from a base station (BS); and

transmitting, to the BS, the HARQ-ACK.

17 . A User Equipment (UE) to transmit Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK), the UE comprising:

a controller to set N pieces of HARQ-ACK to Discontinuous Transmission (DTX) for a cell, based on a difference between KPCeli and KSCell, the difference being associated with the number N, and to generate the HARQ-ACK comprising the N pieces of HARQ-ACK set to DTX, the HARQ-ACK being responsive to data received from a base station (BS), the number N being an integer greater than one; and

a transmitter to transmit, to the BS, the response.
