Channel resource indication method and device

Abstract

The embodiment of the present invention provides a channel resource indication method and a device. The method comprises: request information sent by a station is received by an access point at a first channel, wherein the request information comprises first indication information for indicating that the station is a first type station which supports access point indication channel information, and the first channel is a minimum channel unit; and confirm information is sent to the station by the access point according to the request information, wherein the confirm information comprises channel information for the communication of the access point and the station, and the channel information at least comprises the first channel. According to the method, an access point is allowed to distribute channel resource according to the channel resource and the station types in the same BSS, and then send the confirm information to the station, so as to indicate the access point and the station to communicate on an indicated channel resource, and therefore improving the utilization rate of the channel and the flexibility of resource scheduling.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a channel resource indication method and device. Background technique [0002] In an IEEE802.11 wireless local access network (Wireless local access network, hereinafter referred to as: WLAN), multiple stations (stations, hereinafter referred to as: STA) in the same Basic Service Set (abbreviated as: BSS) share the same spectrum resource , the mechanism for STAs to send data to the Access Point (hereinafter referred to as AP) stipulated in the current standard is: multiple STAs share a channel, and multiple STAs occupy the entire channel for a period of time through the competition mechanism to send data to AP. With the popularization of Wi-Fi (Wireless Fidelity) devices, the number of STAs is increasing, so channel resources are becoming more and more tight. When multiple STAs send Request To Send frames (Request To Send, hereinafter refe...
