METHOD FOR RECEIVING ACK(ACKNOWLEDGEMENT)/NACK (NEGATIVE ACK) INFORMATION AND METHOD FOR TRANSMITTING SAME, USER EQUIPMENT AND BASE STATION

摘要

The present invention relates to a wireless communication system. More particularly, the present invention, when cells each operating in different TDD DL-UL configurations are merged, provides a plan for setting a downlink ACK/NACK transmission/reception timing for a cross-CC scheduling. In addition, the present invention, according to the downlink ACK/NACK transmission/reception timing, provides a base station for transmitting a ACK/NACK channel to a user equipment, and a user equipment for receiving the ACK/NACK channel from the base station.
