Abstract

The invention discloses a data communication method and device. The method provided by the invention comprises the steps that a first network device transmits a first beam identification configuration message to a second network device through a low frequency communication link, wherein the first beam identification configuration message is used for indicating the second network device to measure the beams of a currently transmitted beam identification signal and select the first beam with a first measured value which satisfies a first threshold, and the currently transmitted beam is a part of or all beams of the first network device; the first network device receives first beam selection information transmitted by the second network device; and the first network device establishes a high frequency communication link with the second network device according to the first beam selection information and closes a part of beams of the currently transmitted beam identification signal. According to the invention, the problem of large energy consumption of a high frequency station, which is caused by the fact that high frequency station needs to continuously transmit beams in all directions in the high frequency communication manner in the prior art, is solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a data communication method and device. Background technique [0002] Traditional wireless communication mainly uses spectrum resources between 300 megahertz (MHz) and 3 gigahertz (GHz). With the development of wireless communication technology, the amount of communication data and business scope have been greatly improved. , in order to meet the increasing demand of users for bandwidth and solve the problem of limited spectrum resources in traditional wireless communication, resources of high-frequency bands with higher carrier frequencies have been gradually used for communication. [0003] The high-frequency channel has the disadvantages of large free propagation loss, easy absorption by oxygen, and great influence of rain attenuation, which seriously affects the coverage performance of the high-frequency communication system; however, because the carrier freque...
