Abstract: A transmission control method in a satellite communication system and a related apparatus are provided. A terminal may determine, through satellite selection, a target satellite with a strongest signal from at least one satellite in geosynchronous orbit. The terminal may determine a satellite transmission link direction based on location information of the terminal and location information of the target satellite and may further determine a radiation direction of a satellite antenna in the terminal based on geomagnetic data and attitude data of the terminal. The terminal may enable, by using the satellite transmission link direction and the radiation direction of the satellite antenna, the radiation direction of the satellite antenna in the terminal to be aligned with the target satellite. After aligning with the target satellite, the terminal may send a first data packet to the target satellite along the radiation direction of the satellite antenna.

Abstract: This application provides an uplink data splitting method, a terminal device, and a chip system, and relates to the field of communication technologies. The method includes the following: After determining that a timer expires, a terminal device determines, based on transmission capabilities of an LTE link and an NR link, a data amount of a data package transmitted on the LTE link and the NR link. The transmission capability of the LTE link is determined by the terminal device by transmitting a first detection data package on the LTE link before the timer expires. The transmission capability of the NR link is determined by the terminal device by transmitting a second detection data package on the NR link before the timer expires. The second detection data package is obtained through duplication based on the first detection data package. The terminal device sends same data packages to different communication links to detect transmission capabilities of the communication links. This avoids a phenomenon that data packages wait for each other, and does not affect normal transmission of a data service and user experience for a service.
