<p>The present invention relates to the wireless communications technology, especially relates to a method and device for transmitting feedback information, and the present invention enables the feedback to be performed in an instance that the number of the uplink carriers is different from the number of the downlink carriers in the Long Term Evolution multi-carrier system. The method of the embodiment of the present invention includes the following steps: acknowledgement/negative acknowledgement (ACK/NACK) feedback information indicating whether the downlink sub-frame data needs retransmitting is generated after the user equipment finishes the demodulation and decoding of the downlink sub-frame data; all the determined feedback information is bundled; the bundled feedback information is transmitted through the uplink carrier. Using the method of the embodiment of the present invention, feedback can be improved in the instance that the number of the uplink carriers is different from the number of the downlink carriers, and the system efficiency can be improved.</p> |
