Problems solved by technology

[0004] However, there is no relationship between channel estimation and the sending and receiving directions of communication nodes. This makes most communication nodes on low-frequency channels use omnidirectional data sending and receiving. The signal attenuation is serious and the path loss is large, which affects the quality of information transmission.

Abstract

The embodiment of the invention provides an information transmission method, an initiating node and a response node. The information transmission method comprises the following steps that: the initiating node sends at least one first frame with at least one directional sending direction to a response node on a low-frequency channel for carrying out beamforming training in the sending direction, and receives a second frame comprising a beamforming training result from the response node on the low-frequency channel. According to the embodiment of the invention, the path loss of transmission information on a low-frequency channel can be reduced, and the signal strength is improved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to an information transmission method, an initiating node and a responding node. Background technique [0002] Wireless Local Area Networks (WLAN) can work in low-frequency bands of 2.4GHz and 5GHz, and can also work in high-frequency bands of millimeter waves. [0003] At present, most WLANs work in low-frequency channels. On low-frequency channels, communication nodes need to perform channel estimation before transmitting data. According to the feedback channel status, an idle channel is determined for data transmission. [0004] However, channel estimation has no relationship with the sending and receiving directions of communication nodes. This makes most communication nodes on low-frequency channels use omnidirectional data sending and receiving. The signal attenuation is serious and the path loss is large, which affects the quality of information transmiss...
