Claim:
1. A method for spectral allocation in wireless networks, the method comprising: receiving information pertaining to a preferred spectral path from a mobile device, the preferred spectral path comprising a subset of time-frequency vectors allocated to the mobile device with signal-to-noise ratios (SNRs) higher than a predefined threshold; selecting a particular nearby cluster for the preferred spectral path, wherein the particular nearby cluster corresponds to spatial and temporal grid points near present space-time coordinates of the mobile device; comparing the preferred spectral path to the particular nearby cluster to determine whether the particular nearby cluster has a time-frequency vector distance that is less than a particular threshold; and in response to a determination that the particular nearby cluster has a time-frequency vector distance that is less than the particular threshold, forming a new spectral path by scheduling a next transmission for the mobile device at one or more time-frequency vectors in the particular nearby cluster and adding the new spectral path to a set of spectral paths associated with acceptable performance: else scheduling the next transmission for the mobile device at the preferred spectral path received from the mobile device until another particular nearby cluster is determined to have a time-frequency vector distance that is less than the particular threshold when compared to the preferred spectral path.
