Device-empowered radio resource selection
View Patent ↗A system and method are provided for mitigating interference between wireless access points (APs). A user equipment (UE) device uses a first set of radio resources to wirelessly communicate with a first AP and a second set of radio resources to wirelessly communicate with a second AP. The UE device then uses the first and second radio resources to communicate cooperation data between the first and second access points to mitigate interference thereinbetween.
1. A system for managing radio resources to mitigate interference between wireless access points, comprising:
a first access point and a second access point, wherein the first and second access points are operable to communicate to a plurality of user equipment devices; the first access point using a first set of radio resources to enable a user equipment device of the plurality of user equipment devices to wirelessly communicate with the first access point;
the second access point using a second set of radio resources to enable the user equipment device to wirelessly communicate with the second access point;
the first set of radio resources to communicate cooperation data between the first access point and the user equipment device;
the second set of radio resources to communicate cooperation data between the second access point and the user equipment device;
the first access point communicates an indication of a set of available resources to the user equipment device;
the user equipment device selects a radio resource assignment from the set of available resources, wherein the first set of radio resources is in accordance with the selected radio resource assignment; and the user equipment device communicates the selected radio resource assignment to the second access point for interference avoidance.
2. The system of claim 1 , wherein the user equipment device communicates the selected radio resource assignment to the first access point.
3. The system of claim 2 , wherein
the cooperation data communicated to the first access point and the cooperation data communicated to the second access point each comprise radio channel condition data associated with the first and second sets of radio resources.
4. The system of claim 3 , wherein
the user equipment device communicates the radio resources assignment and the cooperation data to the second access point.
5. The system of claim 4 , wherein
the first access point communicates a confirmation of the radio resource assignment to the user equipment device prior to the user equipment device communicating the radio resource assignment to the second access point.
6. A method for managing radio resources to mitigate interference between wireless access points within a wireless network comprising a first access point and a second access point, the first and second access points being operable to communicate to a plurality of user equipment devices, the method comprising:
enabling the first access point to use a first set of radio resources to enable a user equipment device to wirelessly communicate with the first access point;
enabling the second access point to use a second set of radio resources to enable the user equipment device to wirelessly communicate with the second access point;
communicating, via the first set of radio resources, cooperation data between the first access point and the user equipment device;
communicating, via the second set of radio resources, cooperation data between the second access point and the user equipment device;
communicating, via the first access point, an indication of available resources to of the user equipment device;
selecting a radio resource assignment from the set of available resources, wherein the first set of radio resources is in accordance with the selected radio resource assignment; and the user equipment device communicating the selected radio resource assignment to the second access point for interference avoidance.
7. The method of claim 6 , wherein the user equipment device communicates the selected radio resource assignment to the first access point.
8. The method of claim 7 , wherein
the cooperation data communicated to the first access point comprises radio channel condition data associated with the first and second sets of radio resources and the cooperation data communicated to the second access point comprises radio channel condition data associated with the first and second sets of radio resources.
9. The method of claim 8 , wherein
the user equipment device communicates the radio resources assignment and cooperation data to the second access point.
10. The method of claim 9 , wherein
the first access point communicates a confirmation of the radio resource assignment to the user equipment device prior to the user equipment device communicating the radio resource assignment to the second access points.
11. The system of claim 1 , wherein
the second access point communicates a second indication of a set of second available resources to the user equipment device; and
the user equipment device selects a second radio resource assignment from the set of second available resources,
wherein the second set of radio resources is in accordance with the selected second radio resource assignment.
12. The system of claim 1 , wherein
the user equipment device establishes an indirect connection between the first and the second access points via the first and second sets of radio resources.
13. The method of claim 6 , further comprising:
communicating, via the second access point, a second indication of a set of second available resources to the user equipment device; and
selecting a second radio resource assignment from the set of second available resources,
wherein the second set of radio resources is in accordance with the selected second radio resource assignment.
14. The method of claim 6 , further comprising:
establishing, by the user equipment device, an indirect connection between the first and the second access points via the first and second sets of radio resources.
