METHOD FOR ALLOCATING A PUCCH RESOURCE FOR THE TRANSMISSION OF AN ACK/NACK SIGNAL, AND TRANSMITTING APPARATUS USING SAME

摘要

The present invention relates to a method for transmitting an ACK/NACK signal for hybrid automatic repeat request (HARQ) in a wireless communication system. The method comprises the following steps: receiving a downlink transmission block through a downlink allocation indicated by a downlink control channel; determining a first ACK/NACK resource index and a second ACK/NACK resource index based on at least one of the resources used in the transmission of the downlink control channel; and transmitting an ACK/NACK signal for the downlink transmission block via a plurality of antennas using a first ACK/NACK resource and a second ACK/NACK resource obtained from the first ACK/NACK resource index and the second ACK/NACK resource index. The first ACK/NACK resource index is allocated based on a resource allocation table consisting of a plurality of resource indices corresponding to the transmission bits of the ACK/NACK signal, thus preventing a collision of transmission resources among different antennas and obtaining transmission diversity by means of a multi-antenna system.
