Claims
  • 1. A method, comprising: allocating mobile devices among multiple channels of a radio frequency wireless system based on a variable associated with the transmission power of the mobile devices, the multiple channels being assigned to different portions of a frequency band.
  • 2. A method, comprising: moving at least one mobile device from a first channel of a base station to a second channel of the base station based on a variable associated with the transmission power of the mobile device, wherein:the base station comprises a radio frequency wireless system infrastructure component through which the mobile is communicating; andthe first channel is assigned to a first portion of a frequency band and the second channel is assigned to a second portion of the frequency band, the first portion being different from the second portion.
  • 3. The method of claim 2, wherein: the first portion of the frequency band comprises a frequency range used by the base station to communicate with mobile devices; andthe second portion of the frequency band comprises a frequency range not used by the base station to communicate with the mobile devices.
  • 4. The method of claim 2, wherein the variable associated with the transmission power of the mobile device comprises an estimate of a current transmission power of the mobile device.
  • 5. The method of claim 2, wherein the variable associated with the transmission power of the mobile device comprises an estimate of an average transmission power of the mobile device.
  • 6. The method of claim 2, wherein the variable associated with the transmission power of the mobile device comprises an estimated distance.
  • 7. The method of claim 6, wherein the estimated distance comprises an estimated distance between a location of the mobile device and a location of the base station through which the mobile is communicating.
  • 8. The method of claim 2, wherein the variable associated with the transmission power of the mobile device comprises an estimated transmission power or estimated signal-to-noise ratio of the signal sent by the base station to the mobile.
  • 9. The method of claim 2, further comprising: determining an estimated aggregate power of the mobile devices operating on the first channel; anddetermining a relationship between the estimated aggregate power and a threshold.
  • 10. The method of claim 2, further comprising: sorting a mobiles operating in the first channel according to transmission power settings for the mobiles, the first channel being assigned to a portion of the frequency band covered by a receiver.
  • 11. The method of claim 10, wherein moving the at least one mobile from the first channel of the base station to the second channel of the base station comprises:selecting one or more mobiles from the first channel having the highest transmission power settings; andmoving the one or more mobiles having the highest transmission power settings from the first channel to the second channel.
  • 12. The method of claim 2, further comprising moving a different mobile from the second channel of the base station to the first channel of the base station based on a variable associated with the transmission power of the different mobile.
  • 13. The method of claim 12, further comprising: sorting a plurality of mobiles operating in the second channel according to transmission power settings for the mobiles, the second channel being assigned to a portion of the frequency band not covered by the receiver.
  • 14. The method of claim 13, further comprising moving the different mobile from the second channel of the base station to the first channel of the base station comprises: selecting one or more mobiles from the second channel having the lowest transmission power settings; andmoving the one or more mobiles having the lowest transmission power settings from the second channel to the first channel.
  • 15. A method comprising: determining an estimated aggregate power of a plurality of mobiles operating on a first channel that is assigned to a first portion of a frequency band;determining a relationship between the estimated aggregate power and a threshold;if the relationship between the estimated aggregate power and the threshold meets a condition: sorting mobiles operating on the first channel according to a variable associated with an transmission power;moving at least one mobile from the first channel to a second channel based on the variable associated with the transmission power, the second channel being assigned to a second portion of the frequency band that is different from the first portion of the frequency band;sorting mobiles operating on a second channel according to the variable associated with the transmission power; andmoving at least one mobile from the second channel to the first channel based on the variable associated with the transmission power.
  • 16. An apparatus comprising: circuitry to:assign a first channel of a base station to a first portion of a frequency band;assign a second channel of a base station to a second portion of a frequency band, the second portion being different from the first portion; andmove at least one mobile device from the first channel of the base station to the second channel of the base station based on a variable associated with the transmission power of the mobile device.
  • 17. The apparatus of claim 16, wherein the variable associated with the transmission power of the mobile device comprises a variable selected from the group consisting of an estimate of a current transmission power of the mobile device, an estimate of an average transmission power of the mobile device, an estimated distance, and estimated signal-to-noise ratio of the signal sent by the base station to the mobile.
  • 18. The apparatus of claim 16, further comprising circuitry to: sort mobiles operating in the first channel according to transmission power settings for the mobiles, the first channel being assigned to a portion of the frequency band covered by a receiver; andsort a plurality of mobiles operating in the second channel according to transmission power settings for the mobiles, the second channel being assigned to a portion of the frequency band not covered by the receiver.
  • 19. The apparatus of claim 16, further comprising circuitry to: select one or more mobiles from the first channel having the highest transmission power settings;move the one or more mobiles having the highest transmission power settings from the first channel to the second channel;select one or more mobiles from the second channel having the lowest transmission power settings; andmove the one or more mobiles having the lowest transmission power settings from the second channel to the first channel.
  • 20. An article comprising a machine-readable medium that stores executable instructions causing a machine to: assign a first channel of a base station to a first portion of a frequency band;assign a second channel of a base station to a second portion of a frequency band, the second portion being different from the first portion; andmove at least one mobile device from the first channel of the base station to the second channel of the base station based on a variable associated with the transmission power of the mobile device.
  • 21. The article of claim 20, wherein the variable associated with the transmission power of the mobile device comprises a variable selected from the group consisting of an estimate of a current transmission power of the mobile device, an estimate of an average transmission power of the mobile device, an estimated distance, and estimated signal-to-noise ratio of the signal sent by the base station to the mobile.
