摘要： A method and device for transmitting uplink control information is described. The method includes according to the size and position of a feedback window, determining uplink control information; according to a transmission moment of the uplink control information, performing listen-before-talk detection to determine an actual uplink transmission moment; and transmitting the determined uplink control information at an actual uplink transmission moment. In the embodiments of the present disclosure, under the situation where no channel is occupied at a set uplink control information transmission moment, one or more times of listen-before-talk detection are continued, and the determined uplink control information is transmitted on an actual uplink transmission moment, thereby avoiding the situation that uplink control information may not be correctly transmitted in time due to not occupying a channel, and further improving the system performance.

摘要： 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.

In this solution, a terminal receives configuration signaling sent by a network side, where the configuration signaling instructs to divide M downlink carriers for carrier aggregation into information about N downlink carrier groups, and to configure one uplink carrier for each downlink carrier group; the uplink carrier used for sending acknowledgement feedback information corresponding to downlink data is determined according to the configuration signaling, and the acknowledgement feedback information corresponding to the downlink data is sent to the network side according to a determination result after the downlink data is received. This application solves the problem of how to receive acknowledgement feedback information in the case of aggregation of the TDD carrier and the FDD carrier.
