Abstract: This application provides a data packet processing method and apparatus, applied to a satellite communications system. An earth surface, space, and network space are divided based on a satellite constellation and an ephemeris of a satellite, and an identifier is allocated to each ground area, each space area, and each network that are sub-divisions of the earth surface, space and network space, to establish a fixed mapping relationship between the EID, the SID, and the NID. In addition, each satellite maintains mapping relationship information recording the mapping relationship. Unless a satellite joins the constellation or one satellite leave service, the mapping relationship recorded in the mapping relationship information does not need to be updated. Based on the mapping relationship information, a satellite may route a data packet, thereby reducing a large amount of signaling interaction caused by establishing and maintaining a routing table in the conventional manner.

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 polar encoding method and apparatus. The method can include obtaining a basic sequence, where the basic sequence includes N0 subchannel numbers. The method can also include sequentially reading first subchannel numbers from the basic sequence, and sequentially reading 2m second subchannel numbers from the basic sequence starting from an Mth subchannel number based on the first subchannel number read each time; and adding q*N0 to each of the 2m second subchannel numbers to obtain 2m third subchannel numbers. Furthermore, the method can include constructing a polar code by using subchannels corresponding to the 2m third subchannel numbers as information bits. A polar code with another code length is constructed based on a sequence with a length of N0. A length of a polar code that needs to be stored is therefore reduced, which reduces complexity and is also easy to implement.

Abstract: The present disclosure relates to the communication field and discloses beacon sending and receiving methods and corresponding apparatuses for reducing hardware overheads and weights of a network device such as a satellite or a high-altitude platform and a terminal device such as a ground station. A method is provided that includes determining one or more subcarriers that are in a first frequency band, the first frequency band being one of N frequency bands included in a first beacon resource of the first send node, N being an integer greater than or equal to 1. The first send node sends a beacon signal on the one or more subcarriers. Correspondingly, a first receive node receives the beacon signal on the one or more subcarriers. The first receive node parses the beacon signal.

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.
