Abstract: This application provides a beam switching method and apparatus. The beam switching method includes: A satellite device receives first location information of a terminal device. The satellite device sends first indication information, where the first indication information indicates one or more of K switching time periods. The K switching time periods are determined by the satellite device based on first information. The first information includes the first location information of the terminal device, location information of the satellite device, a velocity vector of the satellite device, and beam information of the satellite device. The K switching time periods are time periods in which the terminal device performs K times of beam switching.

Abstract: A terminal device receives first information, where the first information is for determining first duration, the first duration indicates duration from a moment at which a first beam stops a service to a moment from which a second beam provides a service, and the first beam and the second beam are beams on satellites. The terminal device communicates with a network device by using the second beam based on the first duration.

Abstract: This application provides a communication method and apparatus, to resolve a problem that a quantity of supported beams in an existing solution is limited and therefore a large-scale cell cannot be fully covered, thereby improving reliability of initial access of terminal devices in the large-scale cell. The communication method and apparatus are applicable to various communication systems, for example, an NTN system, a satellite communication system, an aerial platform communication system, an uncrewed aerial vehicle communication system, a 5G system, an internet of vehicles system, and a V2X system. The method includes: generating N SSBs, where N≤Lmax, Lmax>64, Lmax is a maximum quantity of supported sent SSBs, and N is a quantity of SSBs actually sent in one SSB cycle; and sending the N SSBs, where the N SSBs each carry an index i, and i is one of {0, 1, . . . , N−1}.
