Embodiment Construction

[0018] figure 1 A mesh communication network 100 is shown comprising a number of nodes referred to as mesh points 120 , 130 and 140 . Nodes 120 and 130 can forward services of other nodes, and node 140 is a leaf node. A leaf node is a node that does not forward the traffic of another node. In general, each mesh point can be a station or an access point (AP).

[0019] A station is a device that can communicate with another station via a wireless medium. The terms "wireless medium" and "channel" are synonymous and are used interchangeably herein. A station can also be called a terminal, access terminal, mobile station, user equipment (UE), subscriber unit, etc. and can contain some or all of its functionality. A station may be a laptop computer, cellular phone, handheld device, wireless device, personal digital assistant (PDA), wireless modem card, cordless phone, and the like.

[0020] An AP is a station that can provide stations associated with the AP with access to dece...

Abstract

The invention relates to transmission control for wireless communication networks. Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. In another aspect, stations may be assigned different transmission parameter values to achieve the data requirements of each station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and / or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.
