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.

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: 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: An encoding method and apparatus, a decoding method and apparatus, and a device are provided. The encoding method includes obtaining K to-be-encoded bits (S301), where K is a positive integer; determining a first generator matrix, where the first generator matrix includes at least two sub-blocks distributed based on a preset position relationship, and the sub-block includes a plurality of first generator matrix cores (S302); generating a second generator matrix based on the first generator matrix, where the second generator matrix includes T sub-blocks, and a position relationship between two adjacent sub-blocks of the T sub-blocks is determined based on the preset position relationship (S303), where T is a positive integer; and polar encoding the K to-be-encoded bits based on the second generator matrix (S304), to obtain encoded bits. This reduces encoding/decoding complexity.

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: A decoding method includes: decoding first to-be-decoded information based on a first decoder to obtain a first decoding result that includes first soft information or a first hard output; and correcting the first decoding result based on a first correction model to obtain a corrected first decoding result of the first to-be-decoded information. The first correction model is obtained through training based on training data that includes a training decoding result and a corrected training decoding result. The training decoding result is a decoding result obtained after the first decoder decodes training to-be-decoded information, and the corrected training decoding result is a corrected decoding result corresponding to the training decoding result. In this way, after a decoder performs decoding, a decoding result can be corrected based on a correction model.
