摘要： This application provides a satellite communication method and a satellite communication apparatus, to help reduce signaling overheads in a communication process. The method includes: A first satellite obtains a parameter for determining an elevation angle for a departure service of the first satellite in a first serving cell. The first satellite sends first indication information to a terminal device, where the first indication information indicates the elevation angle for the departure service of the first satellite in the first serving cell in which the terminal device is located. The terminal device determines an elevation angle of the terminal device relative to the first satellite based on an ephemeris and location information of the terminal device. The terminal device determines departure service information based on the first indication information, and compares the elevation angle for the departure service with the elevation angle of the terminal device relative to the first satellite, to determine whether to perform satellite reselection or handover.

摘要： Embodiments of this application provide a communication method. The method may include: receiving indication information, where the indication information indicates a first repetition segment duration, the first repetition segment duration is determined based on a first mapping relationship and a current beam elevation angle of a terminal device, and the first mapping relationship includes a correspondence between a beam elevation angle and repetition segment durations; and determining the first repetition segment duration based on the indication information and the first mapping relationship. According to the method, the repetition segment duration of a current information transmission is determined based on a beam elevation angle of the terminal device. This avoids out-of-synchronized communication due to an excessively large accumulated timing advance error caused by a communication device, so that communication efficiency is improved.

摘要： This application provides a communication parameter indication method and an apparatus, to reduce time drift in satellite communication. In the method, a terminal device may obtain first information, where the first information may indicate a quantity of time units of a first message. The first information may be related to a relative speed between a network device and the terminal device. The terminal device may send the first message based on the quantity of time units. Based on the foregoing solution, the first information may indicate the quantity of time units for transmitting the first message by the terminal device, so that time drift caused by a timing advance TA value can be reduced, and transmission performance of an uplink signal can be improved.

摘要： This application provides a bandwidth part switching method, an apparatus, and a system, and may be applied to a non-terrestrial network NTN, to implement BWP switching based on multi-color frequency division multiplexing, and reduce signaling overheads in a BWP switching process. In the method, a terminal device may report, in a second BWP to a network device, an index of a first SSB whose signal quality is greater than or equal to a first threshold in one or more SSBs in a first BWP, and switch from the second BWP to a third BWP. The one or more SSBs correspond to at least one BWP other than the first BWP, and the third BWP is a BWP that is in the at least one BWP and that corresponds to the first SSB. After receiving the index of the first SSB in the second BWP, the network device determines the third BWP, and performs service data transmission with the terminal device in the third BWP.

摘要： Embodiments of this application provide a gateway station switching method and apparatus. When quality of a link from a terminal device to a source gateway station through a satellite is poor, the source gateway station sends third indication information to a target gateway station, so that the target gateway station feeds back second channel quality to the source gateway station, that is, quality of a link from the terminal device to the target gateway station through the satellite. The source gateway station determines, based on the second channel quality and first channel quality that represents the quality of the link from the terminal device to the source gateway station through the satellite, whether to switch the terminal device to the target gateway station. In this process, the source gateway station determines whether to switch the gateway station by comparing the quality of the link from the source gateway station to the terminal device through the satellite and the quality of the link from the target gateway station to the terminal device through the satellite, thereby improving communication quality.
