Method for management of basic service set color, access point and station

Abstract

The embodiment of the invention discloses a method for management of BSS (Basic service set) Color. The method comprises the steps of: sending an indication message to an STA (Station) through an AP (Access Point), wherein the indication message is configured to direct the STA to set the first BSS Color as the BSS Color, wherein the indication message carries the first BSS Color; receiving a confirmation message sent by the STA according to the indication message through the AP, wherein the confirmation message is configured to direct the STA to confirm that the first BSS Color is set as the BSS Color; and employing the first BSS Color to perform communication with the STA through the AP according to the confirmation message. According to the method for management of BSS Color provided bythe embodiment of the invention, after the AP receives the confirmation message sent by the STA, the first BSS Color is employed to perform communication with the STA, and therefore, the packet loss ratio of the STA is reduced, the power waste is reduced, and the spatial multiplex ratio is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically relate to a method, an access point (Access Point, AP) and a station (Station, STA) for managing basic service set colors (Basic service set, BSS) colors (color). Background technique [0002] The BSS color field carries the BSS color. BSS color belongs to a BSS identifier, which is used to assist the station STA to identify the source of the received physical layer protocol data unit (Physical layer protocol data unit, PPDU), that is, from the BSS or from the overlapping basic service set (Overlapped basic service set, OBSS). Due to the limited number of bits in the BSS Color, in places where APs are densely populated, the BSS Color may be repeated, making it impossible for the STA to distinguish the source of the received PPDU. When the STA cannot distinguish the source of the received PPDU, the STA may miss the packet sent by the AP of the real BSS, thus ...

AI Technical Summary

Problems solved by technology

Due to the limited number of bits of the BSS Color, in places where APs are dense, the BSS Color may be repeated, causing the STA to be unable to distinguish the source of the received PPDU

When the STA cannot distinguish the source of the received PPDU, the STA may miss the packet sent by the AP of the real BSS, resulting in STA packet loss and power waste

For another example, when the STA cannot distinguish the source of the received PPDU, the STA may think that the received packet comes from the BSS, so the STA will not perform spatial multiplexing, resulting in a low spatial multiplexing rate
