    Abstract: 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.

    Abstract: The present disclosure provides example acknowledgement information sending and receiving methods, as well as example sending and receiving devices, so that the receiving device synchronously feeds back a receiving status of unicast data and a receiving status of multicast data to the sending device. One example method includes receiving unicast data and multicast data sent by a sending device in a same subframe. A feedback resource is determined according to a data receiving status and a resource mapping relationship, where the data receiving status includes a receiving status of the unicast data and a receiving status of the multicast data, and where the resource mapping relationship indicates a mapping relationship between the data receiving status and the feedback resource. Acknowledgement information is then sent to the sending device by using the determined feedback resource to notify the sending device of the receiving status of the unicast data and the receiving status of the multicast data.
