Method, device and system for communication in wireless local area network

Abstract

Disclosed are a communication method, device and system in a wireless local area network (WLAN), the method comprising: acquiring the association identifier allocated by an access point (AP) to a station (STA); and establishing a corresponding relationship between the address information of the STA and the association identifier, so as to provide relay communication service for the STA and the AP according to the corresponding relationship. The communication method in a WLAN of an embodiment of the present invention provides relay communication service between an STA and an AP via a relay device, and the AP uniformly allocates an association identifier to the STA, such that each relay device does not have to respectively allocate an association identifier to the STA managed by the relay device, thus avoiding conflicts between the association identifiers of the STAs in the basic service set of the AP, thereby facilitating subsequent communication between the AP and the STA, and improving communication efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method, device and system for communication in a wireless local area network. Background technique [0002] In a wireless local area network (Wireless Local Area Network, referred to as "WLAN"), the area covered by an access point is called a basic service set (Basic Service Set, referred to as "BSS"), and multiple stations (Station, “STA” for short) is associated with a corresponding AP, and multiple STAs in the BSS and the corresponding AP work on the same Wireless Fidelity (Wireless Fidelity, “WiFi” for short) channel. In order to enable the STA in the WLAN to enter the sleep state (doze) to save power when no data transmission is required, and to be able to wake up (awake) to receive the AP’s transmission when the AP has data to send to the STA. The 802.11 standard defines a power-saving transmission mechanism: a Traffic Indication Map (Traffic ...

Problems solved by technology

[0004] At present, the 802.11ah working group in the Institute of Electrical and Electronic Engineers (Institute of Electrical and Electronic Engineers, referred to as "IEEE") standards organization has extended the coverage of APs from about 100 meters to 1000 meters in response to the application scenario requirements of sensor networks. , and proposed to support the relay (Relay) function within the coverage area of ​​an AP. However, when a relay device that provides relay communication functions is added to the wireless LAN communication system, how does the relay device provide relay for the AP and the station? The communication service is not clear, and further, it is not clear how to implement the TIM mechanism in the wireless local area network with the addition of relay equipment
