    摘要: A method for optimizing uplink power control settings in a wireless network, the method comprising generating a first gene pool comprising a set of parent genes, wherein each parent gene comprises a set of first generation power control solutions for a set of base stations in the wireless network. The method may further include performing natural selection on the first gene pool to generate a second gene pool comprising selected ones of the set of parent genes, wherein the selected parent genes are chosen by probabilistically selecting some of the parent genes based on fitness values assigned to the parent genes. The method may further include evolving the second gene pool into a descendent gene, wherein the descendent gene comprises a set of local power control solutions for the set of base station in the wireless network.

    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.

    摘要: Methods and systems for providing joint power control (PC) and scheduling in a wireless network are provided. In one example, a method includes generating a near-optimal power pattern for PC and scheduling in accordance with long term channel statistics. The near-optimal PC solution may be generated by first generating a set of possible power patterns in accordance with likely scheduling scenarios, then statistically narrowing the set of possible power patterns to identify the most commonly used power patterns, and finally selecting one of the most commonly used power patterns as the near-optimal power pattern. In another example, a table of optimal PC solutions are provided for performing distributed PC and scheduling in an adaptive and/or dynamic manner.
