Embodiment Construction

[0071] The inventors noticed in the process of the invention:

[0072] Low-track LeO satellite broadband communication systems operate in high-frequency sections such as KU / KA, with high-frequency sections of KU / KA, overlapping the geo satellite signals in the equatorial area, in order to provide broadband data access services. In order to avoid interference with the GEO satellite in the low-rail Leo satellite terminal, the LeO satellite close to the equator is generally adjusted to adjust the satellite antenna coverage area. The ground terminal of the equator area will adjust the antenna to accommodate the beam adjustment of the satellite, so that the uplink signal is to avoid falling into the reception range of the GEO satellite, achieving interference avoidance and elimination.

[0073] In normal beam cover mode, satellite beam is perpendicular to the ground, beam angle is fixed, and the satellite coverage is determined by the system design. It is not necessary to add infor...

Abstract

The invention discloses a satellite beam offset processing method, equipment and a medium. The method comprises the following step: a network side indicates a terminal to a satellite beam offset parameter through a broadcast message and / or a special signaling. The terminal receives a satellite beam offset parameter indicated by the network side through the broadcast message and / or the special signaling; and the terminal adjusts the communication process of the terminal according to the satellite beam offset parameter. According to the invention, even if the LEO satellite adjusts the antenna beam direction in a specific area, the terminal can adjust the communication process of the terminal according to the satellite beam offset parameter, so that the terminal in the beam offset area can continue to work normally, and normal operation of the system under the beam offset condition is facilitated.

Description

Technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a satellite beam bias processing method, a device, and a medium. Background technique [0002] figure 1 Covering the satellite normal mode, as shown, LEO (Low Rail, Low Earth Orbit satellite work coverage mode, satellite beam is not biased, covers the ground area vertically. [0003] In normal coverage mode, the satellite ground coverage is basically fixed, and the satellite beam angular width is basically fixed. [0004] figure 2 Covering the satellite beam bias, as shown, when the satellite covers the equatorial area, in order to avoid signal interference of the GEO (still earth track, Geostationary Earth Orbit satellite, Leo satellite offset beams, beam center There is a bias angle α between the shaft and the vertical vertical shaft. [0005] The prior art is in that the existing satellite communication system cannot guarantee the normal operation of the termina...
