Problems solved by technology

[0003] In practical applications, it is found that when there are many ground terminal devices reporting messages to the satellite at the same time, after the messages sent by some ground terminal devices arrive at the satellite, the signal strength is lower than that sent by other ground terminal devices. Then it is possible to "submerge" in these messages with high signal strength, forming a "near and far effect", resulting in the inability to complete the communication process, which obviously affects the communication quality

Example Embodiment

[0074] The embodiment of the present application provides a terminal device uplink power control method and device, which are used to improve the control accuracy during the control process of the terminal device's uplink power, and then accurately control the signal strength when the message sent by the terminal device reaches the target satellite , thus ensuring that the signal strengths of multiple messages received by the target satellite are consistent, avoiding the "near and far effect", and ensuring the communication quality between multiple terminal devices and the target satellite.

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled ...

Abstract

The embodiment of the invention provides an uplink power control method and device for terminal equipment. A directional diagram off-axis angle of a transceiving antenna of a current target satelliteis accurately determined; and a directional diagram off-axis angle of a transmit-receive antenna of the current terminal equipment, an antenna pattern can be combined; the antenna gain is accurately determined, therefore, the transmitting power of the transmitting and receiving antenna when the terminal equipment transmits the uplink message to the target satellite can be determined more accurately; in a communication process of terminal equipment and a target satellite, control of uplink power is completed, the control precision is improved, the signal intensity of the messages sent by the terminal equipment when reaching the target satellite can be accurately controlled, the signal intensity of the messages received by the target satellite can be ensured to be consistent, the near-far effect is avoided, and the communication quality between the terminal equipment and the target satellite can be ensured after signal interference is eliminated.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method and device for controlling uplink power of terminal equipment. Background technique [0002] After satellites are launched into space, they have a wide range of uses, such as astronomical observation, communication broadcast, scientific research, ground monitoring, etc. During the working process of the satellite, it can communicate with the ground terminal equipment, and the satellite can also forward business data between different terminal equipment. [0003] In practical applications, it is found that when there are many ground terminal devices reporting messages to the satellite at the same time, after the messages sent by some ground terminal devices arrive at the satellite, the signal strength is lower than that sent by other ground terminal devices. Then it is possible to "submerge" in these messages with high signal strength, forming a "near and far ...
