<p>A base station, relay station and transmission method for feedback information are provided by the present invention embodiments, wherein, the method includes of: receiving the data information using the uplink sub-frame transmission from the relay station; returning the feedback information corresponding to the data information to the relay station using the multicast broadcast single frequency network (MBSFN) sub-frame closest to the time sequence position of the uplink sub-frame, so as to shorten the process delay for feedback. Also, another method includes of: determining the multicast broadcast single frequency network (MBSFN) sub-frame closest to the time sequence position of the uplink sub-frame, the uplink sub-frame is used to transfer the data information to the base station; transmitting the time sequence position of the determined MBSFN sub-frame to the base station, so that the base station returns the feedback information corresponding to the data information to the network side. By the present invention embodiments, the feedback information can be transmitted to the relay station using the MBSFN sub-frame closest to the time sequence position of the uplink sub-frame, so as to shorten the process delay for feedback and improve the transmission efficiency of LTE-A system.</p> |
