A method for transmitting data by using hybrid automatic repeat request (HARQ) is provided. A base station allocates a radio resource for a non-acknowledgement (NACK) channel which is used to transmit a NACK signal for multi-user data of a plurality of UEs, transmits the multi-user data, and retransmits the multi-user data when receiving the NACK signal on the NACK channel from at least one UE which receives the multi-user data. |
