A method, a user equipment, and a base station for transmitting channel state information (CSI) used in a scenario of carrier aggregation or a scenario of coordinated multiple point transmission and reception 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. |
