Abstract
The present invention relates to an efficient method of transmitting an ACK / NACK symbol for HARQ of a multi-user MIMO scheme in a wireless communication system. The present invention provides a response message for supporting an automatic retransmission request in a mobile communication system supporting multiple input / output for a plurality of mobile stations. In the transmission method, the same downlink code and I / Q multiplexed response letter are transmitted to two mobile stations using the same uplink resource block, and an efficient ACK / NACK channel transmission method is used when using multi-user MIMO. When using the proposed scheme, the efficiency of downlink radio resources can be improved.
