METHOD FOR TRANSMITTING RESPONSE INFORMATION

摘要

The present invention relates to a method in which a terminal transmits response information on component carriers in a wireless communication system that supports a plurality of component carriers. The method comprises: a step of receiving downlink data from a base station through each of a plurality of downlink resources; and a step of transmitting response information on the plurality of downlink resources through one uplink resource, wherein said one uplink resource includes a first HARQ resource and a second HARQ resource for transmitting the response information. When the response information on the plurality of the downlink resources consists entirely of ACKs, the response information is mapped to the first HARQ resource. When the response information on the plurality of the downlink resources consists entirely of NACKs, the response information is mapped to the second HARQ resource.
