    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 application relates to radio communications and discloses a method and apparatus for feeding back and receiving acknowledgment (ACK) information of semi-persistent scheduling (SPS) data packets. The method includes receiving downlink data packets and an uplink data assignment indicator (UL DAI) from a base station (BS), wherein a value of the UL DAI indicates a number (N) of all scheduled downlink sub-frames which scheduled by the BS for the UE, the number N is greater than 1, and a number k (k

    Abstract: The application relates to radio communication technologies and discloses a method for receiving semi-persistent scheduling (SPS) data packets and sending acknowledgment information of the SPS data packets. A communication apparatus receives physical downlink shared channel (PDSCH) data packets from a base station. The PDSCH data packets include one or more dynamic scheduling data packets and one or more semi-persistent scheduling (SPS) data packets. The communication apparatus sends, to the base station, a sequence including feedback information of the PDSCH data packets. The sequence includes a plurality of bits. Each bit carries an acknowledgement (ACK) or a negative acknowledgement (NAK) to one PDSCH data packet respectively. The bits carrying acknowledgements of the one or more SPS data packets are arranged at the end of the sequence.
