METHOD AND SYSTEM FOR SHARING SPECTRUM IN A WIRELESS COMMUNICATIONS NETWORK
First Claim
1. A method for sharing spectrum in a wireless communications network, comprising the steps of:
- determining if two base stations in the wireless communications network are to share a frequency spectrum;
if two base stations in the wireless communications network are to share a frequency spectrum, determining if the two base stations in the wireless communications network have non-overlapping wireless communications coverage;
if the two base stations in the wireless communications network have non-overlapping wireless communications coverage, determining if a first mobile communications unit associated with a first base station of the two base stations has wireless communications coverage that overlaps with wireless communications coverage of a second mobile communications unit associated with a second base station of the two base stations; and
if the first mobile communications unit has wireless communications coverage that overlaps with wireless communications coverage of the second mobile communications unit, enabling the two base stations to use a synchronized parallel operation spectrum sharing mode for communications.

Abstract
A method and system for sharing spectrum in a wireless communications network are disclosed. As one example, a method for sharing spectrum is disclosed, which includes the steps of determining if two base stations in the wireless communications network are to share a frequency spectrum, and if two base stations in the wireless communications network are to share a frequency spectrum, determining if the two base stations in the wireless communications network have non-overlapping wireless communications coverage. Also, if the two base stations in the wireless communications network have non-overlapping wireless communications coverage, determining if a first mobile communications unit associated with a first base station of the two base stations has wireless communications coverage that overlaps with wireless communications coverage of a second mobile communications unit associated with a second base station of the two base stations, and if the first mobile communications unit has wireless communications coverage that overlaps with wireless communications coverage of the second mobile communications unit, enabling the two base stations to use a synchronized parallel operation spectrum sharing mode for communications. Also, a Contention-for-being-Master approach is disclosed as one primary method for sharing spectrum, which can be treated separately from all other contention methods, or combined with the exemplary contention method disclosed herein.

11. A method for neighbor cells to share a channel in a cognitive radio-based communications network, comprising the steps of:
-
determining if at least two cells in the network have overlapping radio coverage; if at least two cells in the network have overlapping radio coverage, a first cell of the at least two cells determining if a second cell of the at least two cells intends to use a predetermined channel sharing mode for communications, and if the second cell intends to use the predetermined channel sharing mode, enabling the first cell to use the predetermined channel sharing mode for communications; and if the at least two cells in the network do not have overlapping radio coverage, determining if the at least two cells have associated customer premises equipment units that have overlapping radio coverage, and if the at least two cells have associated customer premises equipment units that have overlapping radio coverage, enabling the at least two cells to use a synchronized parallel operation channel sharing mode of communications. - View Dependent Claims (12, 13)

14. A system for sharing spectrum in a wireless communications network, comprising:
-
a first base station arranged in the wireless communications network; a first customer premises equipment unit coupled to the first base station by a first radio air interface; a second base station arranged in the wireless communications network; and a second customer premises equipment unit coupled to the second base station by a second radio air interface, wherein the first base station is configured to; determine if the first base station and the second base station are to share a frequency spectrum; if the first base station and the second base station are to share a frequency spectrum, determine whether or not the first radio air interface and the second radio air interface overlap in communications coverage; if the first radio air interface and the second radio air interface overlap in communications coverage, determine if the second base station intends to use a predetermined channel sharing mode for communications, and if the second base station intends to use the predetermined channel sharing mode for communications, use the predetermined channel sharing mode for communications. - View Dependent Claims (15, 16, 17, 18, 19, 20)
