Abstract: The present invention provides an uplink control information transmitting method and apparatus. In the method, when a user equipment (UE) is configured with an uplink carrier in an unlicensed spectrum, the UE transmits uplink control information through a pre-defined location and a pre-defined format in a licensed spectrum and/or a pre-defined location and a pre-defined format in an idle unlicensed spectrum according to an uplink (UL) grant transmitted from a base station and the UCI to be transmitted. According to the technical solution provided by the present invention, the UCI is flexibly transmitted in the licensed spectrum or in the idle unlicensed spectrum, thereby improving transmission efficiency and reducing impact on downlink signal scheduling when the UE is configured with the uplink carrier in the unlicensed spectrum and transmits the UCI, and further improving LTE network efficiency.
