METHOD FOR MAKING A TERMINAL SEND AN UPLINK ACK/NACK SIGNAL IN A WIRELESS COMMUNICATION SYSTEM USING CARRIER AGGREGATION TECHNIQUES AND APPARATUS FOR THE SAME

摘要

The present application discloses a method for making a terminal send an uplink ACK (acknowledgement)/NACK (negative ACK) signal in a wireless communications system. Specifically, the method includes the steps of: receiving at least one downlink data signal from a network through at least one of a first and second cells; generating an ACK/NACK signal corresponding to the at least one downlink data signal; and sending the ACK/NACK signal through one of the first and the second cells, wherein the structure of the ACK/NACK signal is determined based on the number of the downlink data signals, and if the number of the downlink data signals is plural, the structure of the ACK/NACK signal is first type, and if receiving one downlink data signal through the first cell only or the second cell only, the structure of the ACK/NACK signal is second type.
