Abstract:
1. An uplink feedback method, the method comprising: determining Acknowledgement (ACK)/Non-Acknowledgement (NACK) resource, for carrying ACK/NACK corresponding to downlink data, in a sub-frame n according to a set of sub-frames including a sub-frame in which the downlink data is received; and transmitting ACK/NACK information corresponding to the downlink data over the ACK/NACK resource in the sub-frame n, wherein the set of sub-frames includes a first set of sub-frames and/or a second set of sub-frames; the first set of sub-frames and/or the second set of sub-frames are/is determined by obtained uplink/downlink sub-frame configuration information and flexible sub-frame information; the uplink/downlink sub-frame configuration information indicates the type of each sub-frame in a radio frame, and corresponding types of sub-frames include uplink sub-frames, downlink sub-frames and special sub-frames; and the flexible sub-frame information indicates the type of each sub-frame in a radio frame, and corresponding types of sub-frames include uplink sub-frames, downlink sub-frames, special sub-frames and flexible sub-frames, wherein the flexible sub-frames can be used for transmission of uplink or downlink data, and n is a sub-frame number, wherein the first set of sub-frames includes at least all the sub-frames belonging to both a set P and a set Q; and the second set of sub-frames includes all the sub-frames belonging to the set Q but not the set P, wherein: the set P is determined according to the uplink/downlink sub-frame configuration information, and the set P includes the downlink sub-frames and/or the special sub-frames indicated by the uplink/downlink sub-frame configuration information; and the set Q is determined according to the flexible sub-frame information, and the set Q includes any one or more of the downlink sub-frames, the special sub-frames and the flexible sub-frames indicated by the flexible sub-frame information.
