Abstract: A satellite divides all beam positions in a coverage area of the satellite into K beam position groups based on population density of the beam positions in the coverage area of the satellite, where the K beam position groups are in a one-to-one correspondence with K broadcast beams of the satellite, K is an integer greater than 1, a quantity of beam positions included in a first beam position group is inversely proportional to population density in the first beam position group, the first beam position group is any one of the K beam position groups, and the first beam position group includes at least one beam position. The satellite sequentially performs beam scanning on the beam positions in the first beam position group by using a first broadcast beam corresponding to the first beam position group.

Abstract: This application provides a random access method, an apparatus, and a system, which are applied to the field of communication technologies. The random access method provided in this application includes: First, a terminal device obtains first configuration information, where the first configuration information indicates a maximum quantity of repeated sending times of a preamble, and the maximum quantity of repeated sending times of the preamble is greater than 200. Then, the terminal device sends one or more preambles to a network device based on the first configuration information. According to the method, a current maximum quantity of repeated sending times of the preamble is extended, so that a decoding threshold for decoding the preamble by the network device is reduced, and a low uplink budget requirement of some scenarios can be met.

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}.

Abstract: A communication method and apparatus are provided to reduce interference between different types of satellites. The method is: A terminal device determines a satellite type corresponding to a first area, and the terminal device determines, based on the satellite type, whether to access a network device covering the first area. The terminal device determines, based on the determined satellite type corresponding to the first area, whether the network device can be accessed, so that a type of the network device accessed by the terminal device is consistent with the satellite type of the first area, and the terminal device can access only one type of satellite. When a plurality of types of satellites reuse a same frequency, the terminal device may receive signals of the plurality of types of satellites in the first area.
