Abstract
Disclosed are an uplink control information transmission method and device for addressing a lack of a solution that a terminal provides feedback of downlink carriers scheduled by different base stations in a dual-connectivity scenario. The method in an embodiment of the present application comprises: a terminal receives data over a first carrier and a second carrier, the data over the first carrier being scheduled by a first base station and the data over the second carrier being scheduled by a second base station; the terminal generates first uplink control information for the first carrier, and/or the terminal generates second uplink control information for the second carrier; the terminal transmits the generated uplink control information over one uplink carrier according to a TA value and a reference carrier, the uplink control information comprising at least one of the first uplink control information and the second uplink control information. Therefore, the terminal can simply transmit over one uplink carrier the uplink control information corresponding to the downlink carriers scheduled by different base stations scheduling data for the terminal.
