Embodiment Construction

[0041] First, the way of judging the channel state between offices is described as follows. Please refer to figure 2 , figure 2 It is a schematic diagram of a wireless local area network system 20 according to an embodiment of the present invention. The WLAN system 20 preferably adopts the IEEE 802.11 WLAN standard, but is not limited thereto. Generally speaking, the wireless local area network system 20 includes at least one access point for providing services to multiple office stations. For the convenience of description, figure 2The office stations STA1, STA2 and the corresponding access points AP1, AP2 are drawn in the "office point of view". The so-called "office point of view" is because any office station in the wireless local area network system 20 cannot know whether other office stations belong to the same Basic Service Set (Basic Service Set), so in figure 2 Among them, the office station STA1 or STA2 regards the other party as being served by a different a...

Abstract

The invention discloses a channel state judgment method used in a wireless local area network system, which is used for judging a channel state between a first station and a second station of the wireless local area network system. The channel state judgment method comprises the following steps that: the first station receives a beacon output by an access point; and the first station carries the beacon in a packet and broadcasts the packet, so that the second station can judge the channel station between the first station and the second station according to the packet.

Description

technical field [0001] The present invention relates to a method for judging channel status and a related wireless local area network system and a method for setting up direct links, in particular to a way of forwarding beacons of access points through stations, providing a basis for judging the channel status between stations A state judging method, and a wireless local area network system using the channel state judging method and a direct link setting establishment method. Background technique [0002] In the modern information society, various wireless communication systems have become one of the most important ways for the public to exchange voice or text information, data, and audio-visual files. In order to improve the communication quality, many wireless communication technologies have been developed in the industry to increase the spectrum efficiency and transmission rate of the wireless communication system. [0003] For example, in a wireless communication system...
