Abstract:
1. A method of dynamically scheduling frequency sets for reuse by user devices to reduce inter-cell interference comprising: determining a fairness metric for each user device in a wireless communication region; determining a channel peak desirability metric for each user device, the channel peak desirability metric reflects the instant channel desirability on the user device's best available frequency set relative to the user device's average channel quality; and determining an overall scheduling metric for each user device, the overall scheduling metric is the product of the fairness metric and the channel peak desirability metric determining an overall scheduling metric for each user device, the overall scheduling metric is the product of the fairness metric and a channel delay desirability metric, wherein the channel delay desirability metric is the ratio between the maximum instant spectral efficiency over all free frequency sets and the maximum instant spectral efficiency over all unavailable frequency sets.
