A system access method for high frequency Internet of Things

Abstract

The present invention provides a system access method for the high-frequency Internet of Things, comprising the steps of: the second type of base station sends a beam to the first type of base station in the high frequency band, and then enters a dormant state, and the first type of base station selects the beam with the best receiving quality As a positioning beam; obtain the receiving beam direction used when receiving the positioning beam according to the positioning beam; the first terminal sends an access pilot to the first type of base station through the low frequency band, and then transfers to the high frequency band communication mode; the first type of base station obtains its The optimal spatial beam transmission direction of the first terminal; determine the optimal transmission beam direction for communication with the second type of base station, activate the second type of base station; the second type of base station transmits the beam, and the first terminal sends an access pilot after receiving the beam For the second type of base station, if no response information is received from the second type of base station, it will switch to the low frequency band communication mode to communicate with the first type of base station, and the first type of base station will re-determine the positioning beam. The invention effectively reduces the energy consumption of the internet of things.

Description

technical field [0001] The invention relates to a network access method, in particular to a system access method of the high-frequency Internet of Things. Background technique [0002] 5G will meet the diverse business needs of people in various areas such as living, working, leisure, and transportation, even in dense residential areas, offices, stadiums, open-air gatherings, subways, expressways, high-speed rails, and wide-area coverage.
