METHOD AND APPARATUS FOR TRANSMITTING HARQ ACK/NACK SIGNAL IN MULTI-ANTENNA SYSTEM |
摘要 |
A method and apparatus of transmitting an ACK/NACK signal for a hybrid automatic repeat request (HARQ) in a wireless communication system is provided. A first ACK/NACK resource index and a second ACK/NACK resource index based on resources used to transmit a downlink control channel is determined. An ACK/NACK signal for a downlink transport block is transmitted through a plurality of antennas using first ACK/NACK resources obtained from the first ACK/NACK resource index and second ACK/NACK resources obtained from the second ACK/NACK resource index. An HARQ ACK/NACK signal can be reliably transmitted through a plurality of antennas. |
