    Abstract: This disclosure provides a beam information indication method and an apparatus. The terminal device obtains reference domain information of a plurality of beams and a first offset corresponding to each moment, to update beam domain information, where the first offset indicates an offset of domain information of the plurality of beams relative to the reference domain information of the plurality of beams. In technical solutions provided in this disclosure, domain information of the plurality of beams can be updated with low signaling overheads. The technical solutions may be applied to a satellite communication system, to implement interference management of satellite beams.

    Abstract: This application provides a satellite communication method and apparatus. A terminal obtains a level-1 broadcast signal from a satellite, where a beam status corresponding to the level-1 broadcast signal is an energy saving state, and the level-1 broadcast signal includes synchronization information. The terminal obtains a level-2 broadcast signal from the satellite, where a beam status corresponding to the level-2 broadcast signal is a broadband communication state. The terminal communicates with the satellite based on the level-2 broadcast signal.

    Abstract: Example communication methods and apparatus are described. In one example method, a terminal receives a first information by using a serving beam, where the first information indicates a delay compensation parameter corresponding to a target beam. The target beam and the serving beam are different beams. The terminal determines, based on a full timing advance and the delay compensation parameter corresponding to the target beam, a differential timing advance corresponding to the target beam.

    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 provides a signal transmission method and an apparatus. A network device broadcasts a navigation reference signal and a communication signal. A terminal device may determine its position information based on the navigation reference signal. A communication sequence in the communication signal and a navigation sequence in the navigation reference signal are coupled by using a same even-number-stage m-sequence, so that the terminal device is supported in completing an integrated communication and navigation function based on the broadcast signal.
