Disclosed are a method, user equipment, and base station for information transmission. The method comprises: receiving a downlink assignment transmitted by the base station, where the downlink assignment comprises a trigger identity, while the trigger identity is used for indicating a trigger state of aperiodic channel state information (CSI) (S110); determining an uplink resource used for transmitting the aperiodic CSI (S120); and transmitting the aperiodic CSI on the uplink resource to the base station on the basis of the trigger identity (S130). As the downlink assignment comprises the trigger identity, and the trigger identity is used for indicating the trigger state of the aperiodic CSI, the present invention thus allows for triggering of a feedback of the aperiodic CSI, for reduced control channel overhead, and for improved resource utilization rate of system. |
