Disclosed in the present invention are a method and a device for sending acknowledgement/negative acknowledgement (ACK/NACK) indication information. A network side device configures at least two carriers for a User Equipment (UE), sends Physical Downlink Control Channel (PDCCH) information to the UE, selects one timing relation from at least two timing relations as a first timing relation, determines the corresponding third uplink subframe and a first carrier, indicates the related information corresponding to the third uplink subframe and the first carrier to the UE, determines first channel resource within the third uplink subframe of the first carrier and indicates the first channel resource to the UE, and receives the ACK/NACK fed back from the UE over the distributed resource. |
