Abstract  Abstract

PURPOSE: A method for transmitting a reception confirmation response of user equipment in a wireless communication system and an apparatus are provided to transmit a HARQ(Hybrid Automatic Repeat Request) ACK(Acknowledgement)/NACK(Negative-Acknowledgement) response without errors even when the transmission mode of a serving cell set in a user equipment is changed and to transmit an HARQ ACK/NACK response while reducing the possibility of errors by separating points on a signal constellation to which an HARQ ACK/NACK response is mapped to a maximum extent. CONSTITUTION: A user equipment receives a first transport block from a BS(Base station) through a first serving cell at step S100 and receives a second transport block through a second serving cell at step S200. Here, the assumption is that the first serving cell is set in a first transmission mode which supports up to two transport blocks. The UE determines a first response to the first transport block and a second response to the second transport block at step S300 and sends an HARQ ACK/NACK response according to the first response and the second response to the BS at step S400. Here, if the first transport block has been successfully decoded, the first response is the same as a response in the case where the first serving cell has received all the two transport blocks and has successfully decoded the two transport blocks. Or if the first transport block has not been successfully decoded, the first response is the same as a response in the case where the first serving cell has not successfully decoded all the two transport blocks. (Reference numerals) (S100) Transmitting a first transport block through a first serving cell; (S200) Transmitting a second transport block through a second serving cell; (S300) Determining a first response to the first transport block and a second response to the second transport block; (S400) Transmitting an HARQ ACK/NACK response;
