Resolving spectral allocation conflicts in mobile networks

摘要

Technologies are generally described for reducing spectral allocation conflicts in wireless networks. In some examples, two (or more) wireless devices with intersecting spectral allocation may be identified, followed by determination of one or more time-frequency vectors of the spectral allocation for one of the wireless devices that have a first overlap with one or more time-frequency vectors of the spectral allocation of the other wireless device. For each determined time-frequency vector, an alternate time-frequency vector may be determined such that a second overlap between the alternate time-frequency vector and the time-frequency vectors of the other wireless device is lower than the first overlap. The alternate time-frequency vector may be transmitted to the wireless device to enable that device shift its communication to the alternate time-frequency vector for enhanced communication performance.

1. A method to reduce spectral allocation conflicts in wireless networks, the method comprising:
tracking, by a processor, for a first mobile device with a first spectral allocation, other nearby mobile devices whose spectral intersection with the first mobile device is above a predefined threshold, wherein the redefined threshold is based on a power and complexity of an error-correcting code employed by the first mobile device; identifying, by the processor, a second mobile device with a second spectral allocation from the other nearby mobile devices, wherein there is an intersection between the first spectral allocation and the second spectral allocation; determining, by the processor, one or more time-frequency vectors of the first spectral allocation of the first mobile device with a first overlap with one or more time-frequency vectors of the second spectral allocation of the second mobile device by determining a distance between the time-frequency vectors of the first mobile device and the time-frequency vectors of the second mobile device; and for each determined time-frequency vectors of the first spectral allocation with the first overlap, determining, by the processor, an alternate time-frequency vector such that a second overlap between the alternate time-frequency vector and the one or more time-frequency vectors of the second spectral allocation is lower than the first overlap.
