    Abstract: Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a relay may associate with an access point and then clone the access point by transmitting the service set identifier of the access point. An association between a wireless node and a relay may be formed such that the relay provides relay services for wireless network communication between the access point and the wireless node. In some aspects, the relay may generate messages which communicate its available capacity so that downstream nodes may determine from which relays service may be available. In addition, each node may generate messages for upstream relays which communicate the load an association with the node would cause. Through such communication between relays, admission control may be used to minimize associations being dropped because of insufficient available capacity.

  • Patent number: 9198082
    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.
