Problems solved by technology

[0003] In the non-terrestrial wireless communication (NTN, Non Terrisal Network) architecture based on New Radio (NR, New Radio), due to physical factors such as propagation channel distance, the synchronization between the terminal and the base station is worse than that of the ground cellular system.
Under the same terminal hardware conditions, the pre-synchronization time for the terminal to receive satellites is longer

Abstract

An embodiment of the invention provides a wireless communication method which is applied to a satellite, wherein the method comprises the steps of transmitting configuration information of a trackingreference signal TRS of at least one wave beam to a terminal, wherein the configuration information is at least used for indicating a first time domain position of the TRS transmitted from a satellite; wherein the TRS is used for synchronization between the terminal and the satellite; and the first time domain position is used for determining the awaking time of the terminal in a radio resource control RRC idle state by the terminal.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication but is not limited to the technical field of wireless communication, and in particular relates to a method, device, device and storage medium for wireless communication. Background technique [0002] With the continuous development of wireless communication, people have raised the demand for global signal coverage without dead spots, but ground wireless communication cannot meet some application scenarios of this requirement (for example, signal coverage of isolated islands and deserts, etc.). Therefore, signal coverage by satellite is required. In terrestrial wireless communication networks, all base stations are deployed on the earth. In non-terrestrial wireless communication networks, some or all functions of base stations will be deployed in satellites. The satellite is located high in the sky, and the satellite is far away from the earth. For example, geosynchronous...
