Disclosed in the present invention are a method and apparatus for transmitting uplink control information (UCI), solving the problem of UCI transmission in a short transmission time interval (TTI). The method comprises: a terminal determining a short transmission time interval (TTI) position and/or a short uplink channel for transmitting UCI; and the terminal transmitting the UCI on the determined short-TTI position and/or the short uplink channel, thereby providing a solution for transmitting periodic UCI in a short-TTI, and thus ensuring that the periodic UCI may be normally transmitted in the short-TTI.
