摘要

A METHOD OF TRANSMITTING AN ACKNOWLEDGMENT (ACK)/NON-ACKNOWLEDGEMENT (NACK) SIGNAL IN A WIRELESS COMMUNICATION SYSTEM INCLUDES ASSIGNING AT LEAST ONE ACK CHANNEL AMONG A PLURALITY OF ACK CHANNELS WHICH SHARE AN ACK CHANNEL REGION FOR TRANSMITTING THE ACK/NACK SIGNAL, AND TRANSMITTING THE ACK/NACK SIGNAL THROUGH THE AT LEAST ONE ACK CHANNEL, WHEREIN THE ACK CHANNEL REGION INCLUDES AT LEAST ONE TILE INCLUDING A PLURALITY OF DATA SUBCARRIERS, AND THE ACK/NACK SIGNAL OF EACH ACK CHANNEL IS INDICATED BY MAPPING DIFFERENT ORTHOGONAL VECTORS RESPECTIVELY TO THE PLURALITY OF ACK CHANNELS IN THE TILE.
