    Abstract: Disclosed are a feedback information transmitting method and device, used for addressing a lack of a plan for solving the problem of transmitting uplink control information corresponding to downlink carrier scheduled by a plurality of base stations in a dual connectivity scenario. A terminal of the present invention receives over a first carrier the data scheduled by a first base station, and receives over a second carrier the data scheduled by a second base station; generating first uplink control information for the first carrier, and/or generating second uplink control information for the second carrier; transmitting the generated uplink control information via PUCCH and/or PUSCH over an uplink carrier, the uplink control information comprising at least one of the first uplink control information and the second uplink control information. Therefore, a terminal transmitting uplink control information over only one carrier can send timely feedback of uplink control information corresponding to the downlink carrier scheduled by different base stations, ensuring that different base stations can timely acquire the feedback information corresponding to the downlink carrier scheduled by the different base stations.
