A method, base station, mobile station and communication system for transmitting uplink response signal are provided, wherein, the method includes that: it is judged whether to use the downlink secondary component carrier to send data to a mobile station; if the judgment result is yes, resources are assigned according to the number of the transmission blocks of the downlink data sent on the secondary component carrier, so that the mobile station can select the uplink resources for transmitting response signal from the pre-configured resources corresponding to the primary component carrier and the resources assigned to the secondary component carrier. When resources deficiency occurs, the base station assigns extra resources according to the number of the transmission blocks TB of the transmission data, so that the mobile station uses the pre-configured resources and the resources assigned extra to feed back the response signal, which can reduce the overheard to feed back the response signal, and resolve the problem of resources deficiency. |
