Abstract:
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.
