Abstract: The application provides a communication method, an apparatus, and a system that are used in a satellite network. A user terminal receives, on a management channel, a sounding signal sent by a management satellite. The management satellite manages one or more serving satellites. The user terminal sends a respiratory signal to the management satellite. The respiratory signal carries information about the user terminal. The information about the user terminal is used to determine information about a serving satellite that serves the user terminal. The management satellite or a ground station may uniformly schedule the serving satellite to serve the user terminal. When the serving satellite is switched, a negotiation between satellites may be omitted.

Abstract: A coding scheme determining method and apparatus are provided. In various embodiments, a base station device sends, to a terminal device, higher layer control signaling, physical layer control signaling, or a synchronization signal that carries coding scheme indication information. In some embodiments, a terminal device sends, to a base station device, a capability information report message that carries coding scheme indication information, so that the base station device or the terminal device can clearly and flexibly indicate a coding scheme. At least one information block size IBS greater than or equal to a preset first specified value X is determined, and an IBS is selected from the at least one IBS to code an information block of bits or a code block of the information block of bits. X and a coding scheme are determined by a scenario, information type, and/or service type.
