Embodiments of the present invention provide a method for assisting in uplink transmission and a base station. The method for assisting in uplink transmission includes: acquiring, by a first base station, auxiliary uplink control information of a user equipment; sending, by the first base station, the auxiliary uplink control information to a second base station; and performing, by the second base station, uplink data scheduling for the user equipment according to the auxiliary uplink control information. Therefore, a problem in which the second base station cannot acquire or correctly demodulate uplink information sent by the user equipment and consequently cannot schedule uplink data from the user equipment is solved.
