1. A system for Multi-Cell Interference Management (MCIM) in a wireless network, comprising: a processor configured to: collect data from a neighborhood of base stations in the wireless network; determine local and neighborhood system utility metrics based on the collected data, wherein the determining of the local and neighborhood system utility metrics comprises: for a first subband, weigh a first utility gradient of a first base station based on a first weight to generate a first weighted utility gradient; and for the first subband, weigh a second utility gradient of a second base station based on a second weight to generate a second weighted utility gradient, the first weight being different from the second weight; determine interference managing directives based on the local and neighborhood system utility metrics; create a subband mask based on the local and neighborhood system utility metrics, wherein the subband mask relates to changes in power of radio resources for a plurality of subbands, one value of the subband mask indicating an increase in transmit power for one subband, another value of the subband mask indicating a decrease in transmit power for another subband, the one subband being different from the other subband, and each subband corresponding to a range of frequencies, and wherein the creating of the subband mask is based on the first and second weighted utility gradients; and distribute the subband mask to a MAC layer of a base station in the neighborhood of base stations, wherein the subband mask is applied to implement radio resource usage directives on the base station; and a memory coupled to the processor and configured to provide the processor with instructions.
