Method and apparatus for performing HARQ in a multiple antenna system

摘要

A method of performing hybrid automatic repeat request (HARQ) in a multiple-antenna system includes receiving a plurality of codewords through an uplink channel, generating acknowledgment (ACK)/not-acknowledgment (NACK) signals respectively for the plurality of codewords, and transmitting the plurality of ACK/NACK signals through a downlink channel in association with a resource used in transmission of the uplink channel. ACK/NACK signals for each codeword in multiple antenna system can be transmitted.
