摘要： A method, a user equipment, and a base station for transmitting channel state information (CSI) are disclosed. First, receive a scheduling grant command sent by a base station; then, obtain a CSI location label according to information of a resource occupied by the scheduling grant command and information of a resource occupied by a data channel that is indicated by the scheduling grant command; last, send CSI of a carrier corresponding to the CSI location label to the base station through the data channel. The CSI location label may be obtained through the scheduling grant command, and the CSI of the carrier corresponding to the CSI location label may be sent or received without changing a length of an aperiodic CSI request field. In this way, CSI of a part or all of cells and/or carriers can be triggered flexibly between a user equipment and the base station, and design of the scheduling grant command is simplified.

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 N blocks according to the number N of downlink sub-frames; each downlink sub-frame corresponds to one block according to a predefined mapping label d associating a downlink sub-frame with a block; each block is divided into several sub-blocks; control channel element (CCE) sets within the same sub-frame are respectively mapped to different, m, sub-blocks; the number of sub-blocks in a block corresponds to the maximum value of an indicator corresponding to the number of symbols occupied by the PDCCH associated with the sub-frames; 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.
