The invention provides a method of allocating resources for carrier wave response message feedback and a device. When transmission power control (TPC) command word information in downlink control information (DCI) of auxiliary carrier waves in carrier wave aggregation is different, physical uplink control channel (PUCCH) resources allocated for response message feedback of the auxiliary carrier waves are high-level allocation PUCCH resources appointed by a TPC command word in display control interface (DCI) information which triggers data business on the auxiliary carrier waves. The method of allocating the resources for the carrier wave response message feedback and the device can not only effectively feed back response messages but also effectively restrain the occurrence of unnecessary downlink data retransmission.
