METHOD AND APPARATUS FOR TRANSMITTING RECEPTION ACKNOWLEDGEMENT INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method for configuring an acknowledgement for hybrid automatic repeat request (HARQ), and a user equipment therefore are discussed. The method according to one embodiment includes receiving downlink data through one of first and second downlink component carriers; and determining a resource used for a physical uplink control channel (PUCCH). The resource used for the PUCCH is determined based on a downlink component carrier. If downlink data is received through the first downlink component carrier, the resource used for the PUCCH is determined by using a control channel element (CCE) of a physical downlink control channel (PDCCH). If the downlink data is received through the second downlink component carrier, the resource used for the PUCCH is determined by using a radio resource control (RRC) message. The method according to the embodiment further includes transmitting an acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the downlink data using the resource used for the PUCCH.

1. A method for configuring an acknowledgement for 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 a resource used for a physical uplink control channel (PUCCH) to transmit an acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the downlink data, wherein the resource used for the PUCCH is determined based on a downlink component carrier carrying the downlink data, wherein if the downlink data is received through the first downlink component carrier, 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, and wherein if the downlink data is received through the second downlink component carrier, the resource used for the PUCCH is determined by using a radio resource control (RRC) message; and transmitting the ACK/NACK signal for the downlink data using the resource used for the PUCCH.
