Method and system for autonomous channel coordination for a wireless distribution system
First Claim
1. A method for establishing a coordinated group of access points (APs), the method comprising:
- an AP sending a first beacon periodically, wherein the AP becomes a master of a coordinated group of APs by sending the first beacon including a first field indicating an identity of the coordinated group and a second field indicating that the AP sending the first beacon is the master of the coordinated group; and
the AP receiving a second beacon transmitted by a member AP of the coordinated group, wherein the second beacon includes a third field indicating the identity of the coordinated group that is included in the first beacon.

Abstract
A method and system for autonomous channel coordination for a wireless distribution system (WDS) are disclosed. A wireless communication system includes a plurality of access points (APs) and the APs communicate each other via a WDS. A coordinated channel group (CCG) of a plurality of member APs is established. The member APs of the CCG camp on a WDS channel used for the WDS among the member APs of the CCG. One AP among the member APs of the CCG is designated as a master AP. The master AP coordinates with other member APs of the CCG for selecting and configuring the WDS channel for the CCG and addition and deletion of member APs. By allowing APs to define a CCG, changes of the WDS channel are performed autonomously while maintaining connectivity.

10. An access point (AP) configured to establish a coordinated group of APs, the AP comprising:
-
a controller configured to send a first beacon periodically, wherein the AP becomes a master of a coordinated group of APs by sending the first beacon including a first field indicating an identity of the coordinated group and a second field indicating that the AP sending the first beacon is the master of the coordinated group; and the controller configured to receive a second beacon transmitted by a member AP of the coordinated group, wherein the second beacon includes a third field indicating the identity of the coordinated group that is included in the first beacon. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
