Patent ID: 8374137

Claim:
A method of optimizing multiple cells in a wireless network comprising the steps of: a) identifying a group of cells with at least two cells as neighboring cells; b) identifying a group of users from the group of the cells; b) providing a utility function for each user, where U ij (•) is the corresponding utility function of user i in cell j; c) providing a radio resource allocation objective based upon one cost function for the group of users from the group of cells identified in step a); and d) allocating a portion of a resource to each user in dependence upon a cost function for the group of users; wherein the cost function is given by 1 N ⁢ ∑ j = 1 N ⁢ ( 1 M ⁢ ∑ M j i = 1 ⁢ U ij ⁡ ( r ij ⁡ [ n ] ) ) where r ij [n] is the instantaneous data rate of user i in cell j at time n, U ij (•) is the corresponding utility function of user i in cell j, M j is number of users used in the optimization in cell j, and N is number of neighboring cells used in the optimization.
