摘要： A method for assigning acknowledgement (ACK) channels to a user is used to feed back ACKs of a plurality of downlink sub-frames in one uplink sub-frame. According to the method, reserved ACK channels are divided into blocks according to the number of downlink sub-frames; each downlink sub-frame corresponds to one block; each block is divided into several sub-blocks; control channel element (CCE) sets within the same sub-frame are respectively mapped to different sub-blocks; and the ACK channels are assigned to the downlink sub-frames according to a sequence of increasing a mapping label d first and then increasing a sub-block label m. Thus, more unused ACK channels can be released to form resource blocks (RBs) for transmission on other channels, for example, for PUSCH transmission. Other methods for assigning ACK channels to a user, a device for assigning ACK channels to a user, and a communication system are further provided.
