ACK/NACK METHOD AND TERMINAL FOR MAPPING ACKNOWLEDGE/ NON-ACKNOWLEDGE RESPONSE MESSAGE

摘要

The present invention provides a mapping method of an ACK / NACK response message and a terminal. The method comprises the steps of: determining whether an ACK / NACK signal is to be fed back by the UE based on a predetermined condition including at least one of a number of downlink component carriers or cells allocated to the UE by the base station and a transmission mode of each downlink component carrier; NACK) response message, and mapping the ACK / NACK response message to L bits. According to the present invention, an ACK / NACK response message can be correctly processed.
