Problems solved by technology

[0003] However, for high-frequency systems, if the RTS / CTS handshake mechanism is still used, it will not be able to assist the transceiver equipment to avoid interference, which will increase the time overhead for discovering the transmittable beam direction

Abstract

The invention provides a data transmission method and device. The method comprises that first network equipment obtains information of a first wave beam which is transmitted by second network equipment; the first network equipment determines a target wave beam according to the information of the first wave beam; and the first network equipment uses the target wave beam for transmission. The data transmission method and device can be used to avoid interference.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a method and device for transmitting data. Background technique [0002] The wireless local area network (Wireless Local Area Network, WLAN) low-frequency system works in the unlicensed low-frequency band, and uses omnidirectional antennas or quasi-omnidirectional antennas to provide coverage. In order to avoid interference to other users, a Wireless-Fidelity (Wireless-Fidelity, WI-FI) device needs to listen to a channel before sending data. Data can only be sent when the channel is detected to be idle. In this way, there will still be interference problems caused by hidden nodes. Therefore, the WI-FI system introduces a request to send (Request To Send, RTS) / clear to send (Clear To Send, CTS) handshake mechanism, by carrying information such as the address of the sender and receiver and the duration of data transmission in the handshake message. Data transmission ...
