The longest TR pattern may include a plurality of TR sub-patterns of different lengths. For example, a first TR pattern of a first length is a sub-pattern of the longest TR pattern, and a second TR pattern of a second length is also a subset of the longest TR pattern.

Abstract: This application provides example satellite communication methods and example apparatuses. One example method includes receiving, by a terminal device, first information sent by a satellite, where the first information indicates a first timing change rate range. The terminal device can then measure a downlink timing change rate to obtain a first downlink timing change rate. The terminal device can then determine a first uplink timing change rate based on the first downlink timing change rate and the first timing change rate range. The terminal device can then perform uplink communication with the satellite based on the first uplink timing change rate.

Abstract: Embodiments of this application relate to the field of communication technologies, and provide a timing offset parameter update method, a device, and a system, to help reduce signaling overheads when a terminal device updates a value of a timing offset parameter. The method includes: A terminal device obtains a timing advance adjustment variation corresponding to the terminal device, where the timing advance adjustment variation is a difference between a timing advance adjustment amount currently used by the terminal device and a timing advance adjustment amount used at a previous moment. The terminal device determines whether an absolute value of the timing advance adjustment variation is greater than or equal to a first threshold. If the absolute value is greater than or equal to the first threshold, the terminal device sends, to a network device, first indication information used to indicate an update regularity of a timing offset parameter.
