Abstract:
1. A method for configuring an acknowledgement for a hybrid automatic repeat request (HARQ) in a wireless communication system, the method comprising: receiving downlink data through one of a first downlink component carrier and a second downlink component carrier from a base station; determining whether the first downlink component carrier or the second downlink component carrier is used for receiving the downlink data; and determining a resource used for a physical uplink control channel (PUCCH) to transmit an ACK/NACK signal for the downlink data in accordance with the determination, wherein if the first downlink component carrier is used for receiving the downlink data, the resource used for the PUCCH is determined by using a control channel element (CCE) of a physical downlink control channel (PDCCH) associated with the downlink data, wherein if the second downlink component carrier is used for receiving the downlink data, the resource used for the PUCCH is determined by using a radio resource control (RRC) message, and wherein the resource used for the PUCCH is associated with an orthogonal sequence with which the ACK/NACK signal is spread.
