and further comprises: acquiring, by the RNC, a target power control value, wherein the target power control value is used to ensure that channel quality of an uplink control channel from the first terminal to the macro base station reaches a target threshold; and sending (203, 405, 507), by the RNC, the target power control value to the micro base station, so that the micro base station controls uplink transmit power of the first terminal according to the target power control value; wherein the method further comprises: acquiring, by the micro base station, the target power control value sent by the RNC; and controlling, by the micro base station according to the target power control value, uplink transmit power of the first terminal, wherein the first terminal establishes a connection with both the macro base station and the micro base station, and a downlink serving base station of the first terminal is the macro base station; wherein after the controlling, by the micro base station according to the target power control value, uplink transmit power of the terminal, the method further comprises: receiving, by the micro base station, user information that is of a second terminal in an adjacent cell of the micro base station and that is sent by the RNC; and canceling, according to the user information of the second terminal, a target uplink interference signal of the first terminal from an uplink signal that is of the first terminal and that is received by the micro base station. determining (201, 401, 501), by the RNC, that a downlink serving base station of a first terminal that establishes a connection with both the macro base station and the micro base station is the macro base station;
