Abstract
This invention provides wireless resource allocation techniques where the wireless network resource allocation is based on maximum system gain. System gain may be the difference between a maximum performance (e.g., throughput rate) for a requested link and a performance loss of all currently active links affected by the requested link. A currently active link is affected if the requested link is within its link neighborhood. Wireless network resources are allocated to optimize system performance. Inter-base communication may be used to facilitate information exchange among base stations to optimize system performance. The performance loss experienced by any currently active link is called damage to that link. Damage may be determined in a pair-wise fashion based on a nominal performance which may be defined as the performance of a link if interference is experienced only from links which are outside the link neighborhood of the link or as a system parameter. The damage is the difference between the nominal performance and the performance for the link if experiencing interference only from the requested link. Determining damage is computationally efficient because it only requires consideration of the nominal performance and the performance of the requested link. Link neighborhoods limit inter-base station communications and reduces base station interconnect costs.
