Method and system for dynamic, joint assignment of power and scheduling of users for wireless systems
Abstract:
A method for dynamically determining power and scheduling assignments in a communications network includes selecting, by a controller, a mobile station in each cell to define a mobile station set, determining, by the controller, a power allocation for each of the mobile stations in the mobile station set, calculating, by the controller, a global utility function by evaluating a contribution from each of the mobile stations in the mobile station set in accordance with the power allocation, repeating, by the controller, the selecting, the determining, and the calculating steps a predetermined number of times to generate additional ones of the global utility function, and choosing, by the controller, the mobile station set corresponding to the global utility function having a particular value for a resource block of a frame. The method may also include repeatedly dividing a user set into clusters to obtain a best power allocation.
