Abstract: A communication method and apparatus are provided, and relate to the field of wireless communication technologies, to resolve a problem in a conventional technology that communication quality during communication between a satellite and a communication apparatus cannot be ensured, and to ensure security of high-accuracy location information of the satellite. In the method, the communication apparatus may perform random access to the satellite based on first location information. The communication apparatus may perform uplink communication with the satellite based on obtained second location information. Accuracy of a location obtained based on the second location information is higher than accuracy of a location obtained based on the first location information. Based on this solution, required accuracy of location information of the satellite is different.

Abstract: This application provides a gateway handover method and an apparatus, to ensure the reliability of a gateway handover of a terminal device and reduce hardware overheads in a gateway handover process. The terminal device receives a synchronization signal/PBCH (physical broadcast channel) block (SSB) from a network device through a service link. The SSB includes an SSB of a source gateway and an SSB of at least one candidate target gateway. The terminal device obtains a measurement value of channel quality corresponding to the SSB of the at least one candidate target gateway, and sends a measurement result to the network device. The network device forwards the measurement result to the source gateway, which determines, based on the measurement result, whether to hand over the terminal device from the source gateway to one of the at least one candidate target gateway.

Abstract: The disclosure provides transmission methods and apparatuses. One example includes sending control signaling to a terminal device, to indicate the terminal device to send a physical uplink shared channel (PUSCH) on a first frequency band; and receiving the PUSCH sent by the terminal device on the first frequency band. The first frequency band includes at least one guard subcarrier. A quantity of the at least one guard subcarrier is determined based on a Doppler frequency shift of a beam covering the terminal device. The first frequency band is located on a frequency band corresponding to the beam.

Abstract: This application discloses example signal sending methods and apparatuses, and example signal processing methods and apparatuses. One example method includes generating, by a terminal device, a channel sounding reference signal (SRS). The terminal device can then send the SRS to a target base station, where the target base station detects, by using the SRS, that a change range of an uplink timing location of the terminal device is not less than a length of one SRS symbol.

Abstract: Embodiments of this application disclose a communication processing method, including: A first communication device determines a first tone reservation pattern. The first communication device communicates a data signal by using the first tone reservation pattern. The first tone reservation pattern is determined based on a first bandwidth part BWP, or the first tone reservation pattern is determined based on a first beam. The first bandwidth part is used for communicating the data signal between the first communication device and a second communication device, and the first beam is used for communicating the data signal between the first communication device and the second communication device. It can be learned that the first tone reservation pattern is more suitable for the first communication device and the second communication device.
