Abstract: A method for configuring an acknowledgement for a hybrid automatic repeat request (HARQ) in a wireless communication system. The method includes receiving downlink data through one of a first downlink component carrier and a second downlink component carrier from a base station; and determining whether the first or second downlink component carrier is used for receiving the downlink data. 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). 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. The resource used for the PUCCH is associated with an orthogonal sequence with which the ACK/NACK signal is spread.

Abstract: A method for transmitting an uplink signal by a user equipment (UE) in a wireless communication system. The method according to one embodiment includes receiving, by the UE, a physical downlink control channel (PDCCH) via one or more resource units; receiving, by the UE, a physical downlink shared channel (PDSCH) indicated by the received PDCCH; and transmitting, by the UE, a physical uplink control channel (PUCCH) using a PUCCH resource in response to the received PDSCH. An index of the PUCCH resource is determined by adding a first index offset and a second index offset to a lowest index of the one or more resource units. The first index offset is signaled via the PDCCH and the second index offset is signaled via higher layer signaling.
