Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] The embodiment of the present invention can be applied to a WLAN, and currently the standards adopted by the WLAN are IEEE 802.11 series. A WLAN can include multiple Basic Service Sets (Basic Service Set, BSS). The network nodes in the Basic Service Set are stations, and the stations include access point stations (Access Point, AP) and non-access point stations (None Access Point Station, Non-AP STA), in the embodiment of the present invention, ...

Abstract

The embodiment of the invention discloses a scheduling method and device of a channel resource. The scheduling method of the channel resource comprises the following steps: an access point sends a management frame, the management frame comprises directional channel quality measurement information, wherein the directional channel quality measurement information comprises identifiers of at least two alternative station pairs selected by the access point and used for performing the channel quality measurement, and the channel resource distributed for each alternative station pair in at least two alternative station pairs and used for the directional channel quality measurement; the access point receives a directional channel quality measurement report returned by each alternative station in at least two alternative station pairs, selects at least two target station pairs to perform the space sharing according to the directional channel quality measurement report of each alternative station, and indicates a time domain overlapped channel resource for performing space sharing to at least two target station pairs. By use of the scheduling method disclosed by the embodiment of the invention, the directional channel quality measurement information can be carried in the management frame, thereby saving the channel resource and improving the system efficiency.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a channel resource scheduling method and device. Background technique [0002] IEEE 802.11ad is a technical protocol that regulates wireless local area network (Wireless Local Area Network, WLAN) equipment working in the 60GHz frequency band. The network that uses the 802.11ad protocol for communication is usually called a Directional Multi Gigabit (DMG) network. A DMG network usually consists of one access point and multiple stations. Unlike other WLAN protocols, due to the characteristics of the 60GHz frequency band, before communication between an access point and a station, or between two stations, generally a Carry out beamforming training (beamforming training, BF training), find out the transmitting antenna mode and / or receiving antenna mode suitable for each other, and then use the antenna mode for communication. [0003] Optionally, the transmitting antenna pa...
