Embodiment Construction

[0025] In the prior art, the process of establishing a connection between a Station device and an AP device through a WLAN network is as follows: figure 1 shown.

[0026] Step 1: The Station device sends an identity authentication request (Auth request) to the AP device;

[0027] Step 2: The AP device returns an identity authentication response (Auth response) to the Station device;

[0028] Step 3: The Station device sends an association request (Association request) to the AP device;

[0029] Step 4: The AP device returns an association response (Association response) to the Station device;

[0030] Step 5: EAPOL (Extensible Authentication Protocol Over LAN, Extensible Authentication Protocol Over LAN) four-way handshake is performed between the Station device and the AP device;

[0031] Step 6: DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) interaction is performed between the Station device and the AP device.

[0032] Among them, in ste...

Abstract

The present invention relates to the technical field of wireless communication and particularly relates to a beamforming ability matching method and a communication device which are used to solve theproblem that the data transmission is abnormal since a Station device and an AP device perform beamforming processing on data to be transmitted by using different detection modes and the Station device and the AP device cannot communicate normally in the prior art. In the embodiment of the invention, in the process of establishing a connection between a first device and a second device, the firstdevice acquires beamforming ability information supported by the second device, according to beamforming ability information supported by the first device and the beamforming ability information supported by the second device, the beamforming ability information supported by the first device and the second device is determined. The beamforming ability information is sent to the second device suchthat the beamforming processing of a transmitted signal is performed according to the beamforming ability information when the signal is transmitted between the first device and the second device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a beamforming capability matching method and communication equipment. Background technique [0002] As WLAN (Wireless LAN, wireless local area network) has higher throughput requirements, a beamforming (Beamforming) technology that can improve signal quality has gradually become popular in WLAN. Beamforming is a general signal processing technique used to control the direction of propagation and reception of radio frequency signals. [0003] The beamforming technology stipulated in the 802.11n protocol needs the support of the Station (client) equipment. In order to enable each Station equipment to enjoy the advantages brought by the beamforming technology to a certain extent, the AP (AccessPoint, access point) equipment in the WLAN Beamforming processing is performed on the signal when transmitting the signal with the Station device. Beamforming supports two typ...
