The invention provides a response message feedback method and a device, wherein a response message encoding method comprises a receiving component carrier, which comprises at least one descending sub-frame; response massage bits corresponding to the component carrier are generated according to the received component carrier; the response massage bits are divided into two groups so that each group comprises at least one response massage bit, the at least one response massage bit corresponds to physical downlink shared channel (PDSCH) transmission and/or descending control information (DCI), the DCI is used to instruct the stoppage of descending semi-persistent dispatching (SPS); two groups of code word bits are obtained by encoding the two divided groups of response massage bits, total code word bits to be transmitted are generated by the two groups of response massage bits obtained by respective encoding. The invention further comprises a response message receiving method, a response message encoding device and a device for processing the response message.
