Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] First of all, the embodiment of the present invention is mainly aimed at the scene where the cell moves relative to the ground in the NTN. By receiving the cell moving speed information sent by the network side, the terminal can know the motion information of the relevant cell, so that the terminal can know the motion information of the relevant cell, so as to execute the cell motion state. When relevant communication behaviors are performed, the...

Abstract

The present invention provides an information acquisition method, a sending method, a terminal, and a first network device, wherein the information acquisition method includes: receiving cell movement speed information sent by the first network device; the cell movement speed information includes: the Cell movement speed information of the first network device, and / or cell movement speed information of a second network device adjacent to the first network device. The solution of the present invention can enable the terminal to know the motion information of the relevant cell, so that when executing the communication behavior related to the motion state of the cell, especially in the scene where the cell moves relative to the ground, it can ensure the effective execution of the corresponding communication behavior.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an information acquisition method, a sending method, a terminal and a first network device. Background technique [0002] In the non-terrestrial network (Non-Terrestrial Network, NTN), different from the traditional terrestrial cellular network, its network equipment such as base stations are deployed on high-altitude flight platforms (balloons, drones, etc.) or satellites, and the ground height is usually above 8km. It has the advantages of wide coverage, line-of-sight transmission, and not affected by ground disasters. As an effective supplement to traditional terrestrial cellular networks, NTN can meet the network coverage needs of remote areas or geographically isolated areas (such as islands, civil aviation aircraft, and ocean-going ships), and improve the reliability of communication networks (especially in sudden disasters). [0003] In traditional te...
