摘要： One embodiment of the present invention provides a system for setting uplink power-control parameters for a cell within a wireless network. During operation, the system receives parameters associated with uplink power for a plurality of user devices within the cell over a predetermined time interval, and averages the received parameters over the user devices and the predetermined time interval to obtain an averaged parameter. The system then determines a set of power-control parameters for the cell based on the averaged parameter, and sends the set of power-control parameters to the user devices to allow the user devices to control transmission power using the set of power-control parameters.

摘要： For each base station, transmit power level variables (I values) for each resource block allocated by the base station are initialized. The I values are used in a model to find sub-gradients for each base station. Neighboring base stations exchange the sub-gradients. For each base station, the base station's sub-gradient and the base station's neighbors' sub-gradients are used in the model to update the I values. Neighboring base stations then exchange the updated I values. For each base station, the base station's updated I value and the base station's neighbors' updated I values are used in the model to update the initial sub-gradients. The updated sub-gradients are then exchanged and used for another update of the I values. After a number of iterations, the I values are used to establish a transmit power level per resource block.
