Problems solved by technology

[0004] However, manual configuration and setup processing is cumbersome, error-prone, and costly
In addition, due to interference and changes in business conditions, the most suitable WDS channel for WDS internal communication will change dynamically in the short term
It is impractical to manually track these changes and change the WDS channel

Embodiment

[0041] 1. A method for implementing autonomous channel coordination for a WDS in a wireless communication system comprising a plurality of APs, wherein the APs communicate with each other via the WDS.

[0042] 2. The method as described in embodiment 1, comprising the following steps: establishing a CCG including a plurality of member APs, and the member APs of the CCG reserve the WDS channel used by the WDS between the member APs of the CCG.

[0043] 3. The method as described in embodiment 2, comprising the following steps: designate one of the member APs of the CCG as the master AP.

[0044] 4. The method according to embodiment 3, comprising the following steps: the master AP coordinates with other CCG member APs to select and configure a WDS channel for the CCG.

[0045] 5. The method according to any one of embodiments 2-4, wherein each member AP of the CCG broadcasts the CCGI on the WDS channel.

[0046] 6. The method of embodiment 5, wherein the CCGI is transmitted by...

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.

Description

technical field [0001] The present invention relates to wireless communication systems. More specifically, the present invention relates to a method and system for implementing autonomous channel coordination for a Wireless Distributed System (WDS). Background technique [0002] In WLAN systems such as 802.11, stations (STAs) inside a basic service set (BSS) communicate with each other by sharing the same frequency channel. In a BSS in infrastructure mode, Access Points (APs) relay traffic to and from Distributed Systems (DSs). Many BSSs can be connected to DSs via their APs. Communication between the AP and other nodes within the DS can be supported by any Media Access Control (MAC) scheme, eg IEEE802.3 if a wired infrastructure exists. Communication between APs can also be wireless if no wired infrastructure exists. A group of APs communicating wirelessly constitutes a WDS. [0003] For successful communication between two APs in a WDS, the sending AP must send packet...
