The invention discloses methods and a system for controlling the uplink transmitting power of a terminal. The methods are applied to a system consisting of a plurality of adjacent base stations. One method comprises the steps of: reporting information of all interference base stations which interfere the terminal on uplink data transmission to a service base station; and acquiring a loss value of an uplink propagation path between each interference base station and the terminal by the service base station according to the received information of the all the interference base stations, then, working out the uplink transmitting power of the terminal according to the accumulated loss values of the uplink propagation paths and a preset control factor of interference-to-noise ratio in the local base station, and configuring the terminal with the uplink transmitting power. The other method comprises the steps of: reporting downlink signals between the terminal and the service base station, the interference-to-noise ratio and a propagation path loss value, which are measured by the terminal, to the service base station by the terminal; and by taking the accumulated sum of the received downlink signals, the interference-to-noise ratio and the propagation path loss value as well as the preset control factor of the interference-to-noise ratio in the local base station as the uplink transmitting power of the terminal, configuring the terminal with the uplink transmitting power by the service base station.
