Abstract
An apparatus and method for providing bandwidth on demand service in a wireless communication system having at least one user station, including a frequency divider for dividing a selected bandwidth into a plurality of frequency subdivisions. Also included is a unit for assigning a first number of frequency subdivisions to the individual user stations having a first total bandwidth, commensurate with the volume of transmission traffic. There also is a unit for changing the first number to a second number having a second total bandwidth commensurate with the change of the volume of transmission traffic.
Claims54
A method of providing bandwidth on demand service in a wireless communication system having at least one user station, comprising the steps of:
- dividing a selected bandwidth into a plurality of frequency subdivisions;
- assigning a first number of said frequency subdivisions to an individual user station in said wireless communication system, each of said user stations having a volume of transmission traffic, said first number of said frequency subdivisions having a first total bandwidth commensurate with said volume of transmission traffic of said individual user station;
- and
- changing said first number of frequency subdivisions to a second number of frequency subdivisions as said volume of transmission traffic of said individual user station changes, said second number of frequency subdivisions having a second total bandwidth commensurate with said volume of transmission traffic of said individual user as said volume of transmission traffic changes.
A method of providing bandwidth on demand service in a wireless communication system having at least one user station, comprising the steps of:
- dividing a selected bandwidth spectrum into frequency subdivisions of various bandwidth sizes;
- assigning a first frequency subdivision to an individual user station in said wireless communication system, each of said user stations having a volume of transmission traffic, said first frequency subdivision having a first bandwidth commensurate with said volume of transmission traffic of said individual user station;
- and
- assigning a second frequency subdivision to said individual user station when said volume of transmission traffic of said individual user station changes so that a combined bandwidth of said first and said second frequency subdivision is commensurate with volume.
A method of providing bandwidth on demand service in a wireless communication system having at least one user station, comprising the steps of:
- dividing a selected bandwidth spectrum into frequency subdivisions of various bandwidth sizes;
- and
- assigning a set of multiple frequency subdivisions to an individual user station so that in combination said multiple frequency subdivisions have a bandwidth commensurate with a volume of transmission traffic of said individual user station;
- adding frequency subdivisions to said set of multiple frequency subdivisions so that said bandwidth remains commensurate with said volume of transmission traffic of said individual user station as said volume increases;
- and
- deleting frequency subdivisions from said set of multiple frequency subdivisions so that said bandwidth remains commensurate with said volume of transmission traffic of said individual user station as said volume decreases.
A method of providing bandwidth on demand service in a wireless communication system having at least one user station, comprising the steps of:
- dividing a selected bandwidth into frequency subdivisions of equal bandwidth size;
- assigning a first number of said frequency subdivisions to an individual user station in said wireless communication system, each of said user stations having a volume of transmission traffic, said first number of said frequency subdivisions having a total bandwidth commensurate with said volume of transmission traffic of said individual user station;
- and
- changing said first number of frequency subdivisions to a second number of said frequency subdivisions as said volume of transmission traffic of said individual user station changes, said second number of frequency subdivisions having a total bandwidth commensurate with said volume of transmission traffic of said individual user as said volume of transmission traffic changes.
Apparatus for providing bandwidth on demand service in a wireless communication system having at least one user station, comprising:
- a frequency divider for dividing a selected bandwidth into a plurality of frequency subdivisions;
- means for assigning a first number of said frequency subdivisions to an individual user station in said wireless communication system, each of said user stations having a volume of transmission traffic, said first number of said frequency subdivisions having a first total bandwidth commensurate with said volume of transmission traffic of said individual user station;
- and
- means for changing said first number of frequency subdivisions to a second number of frequency subdivisions as said volume of transmission traffic of said individual user station changes, said second number of frequency subdivisions having a second total bandwidth commensurate with said volume of transmission traffic of said individual user as said volume of transmission traffic changes.
