Systems, apparatus, and methods for range extension of wireless communication
First Claim
1. A method of wireless communication, comprising:
- at a relay apparatus associated with one or more other devices, receiving a first message from a downstream relay, wherein the first message includes an indication of a number of devices that are associated with the downstream relay;
generating a second message for an upstream relay in response to the first message, wherein the second message is a request for an available capacity of the upstream relay;
transmitting the second message to the upstream relay;
receiving a response message from the upstream relay, the response message indicating the available capacity of the upstream relay; and
determining whether the relay apparatus can serve the downstream relay based on the available capacity of the upstream relay.

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.
