Resolving spectral allocation conflicts in mobile networks

A controller for a wireless network configured to employ spectral allocation conflict reduction, the controller comprising:

• a communication module configured to communicate with a plurality of mobile devices, including at least a first mobile device and a second mobile device, over a wireless network;
• a memory configured to store instructions;
• and
• a processor coupled to the communication module and the memory, wherein the processor comprises:
• an analysis module configured to:
• for the first mobile device with a first spectral allocation, identify the second mobile device with a second spectral allocation, wherein there is an intersection between the first spectral allocation and the second spectral allocation;
• determine, for the first mobile device, one or more time-frequency vectors of the first spectral allocation with a first overlap with one or more time-frequency vectors of the second spectral allocation of the second mobile device;
• and
• for each determined time-frequency vector of the first spectral allocation with the first overlap, determine 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 lower than the first overlap by:
• determining one or more time slots of each determined time-frequency vector within the first overlap;
• and
• for each of the determined time slots, selecting an unoccupied time slot nearest to the each of the determined time slots to change a frequency allocation;
• and
• a spectral allocation module coupled to the analysis module, the spectral allocation module configured to transmit the alternate time-frequency vector to the first mobile device by transmitting a set of frequencies to be used in successive time slots.

An analysis server to analyze sub-carrier allocation data to categorize clusters for predictive spectral allocation in wireless networks, the analysis server comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory, wherein the processor comprises:
• an analysis module configured to:
• track, 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 redefined threshold, wherein the predefined threshold is based on a power and complexity of an error-correcting code employed by the first mobile device;
• identify 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;
• determine, for the first mobile device, one or more time-frequency vectors of the first spectral allocation with a first overlap with one or more time-frequency vectors of the second spectral allocation of the second mobile device;
• and
• for each determined time-frequency vector, determine 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 lower than the first overlap by:
• determining one or more time slots of each determined time-frequency vector within the first overlap;
• and
• for each of the determined time slots, selecting an unoccupied time slot nearest to the each of the determined time slots to change a frequency allocation.
