Abstract: Example methods and apparatus for determining a timing advance are described. One example method includes obtaining ephemeris information of a satellite, where the ephemeris information includes coordinates of the satellite and an ephemeris error of the satellite. A timing advance is determined according to a preset rule based on the ephemeris information and location information of a terminal device, where the location information includes coordinates of the terminal device and a positioning error of the terminal device. The preset rule is determined by using a first horizontal distance, a first vertical distance, the ephemeris error, and the positioning error.

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.

Abstract: This application provides a polar coding method, a polar decoding method, and an apparatus. A transmit end obtains K to-be-coded bits and an index set including K polar channels, where a value set of K1 indexes in the set of the K indexes or a value set of K2 indexes in the set of the K indexes is determined based on a value set of K2 of the K to-be-coded bits, and the value set of the K1 indexes and the value set of the K2 indexes are complementary sets of each other; and performs polar coding on K1 to-be-coded bits. In comparison with a conventional polar coding method and a conventional polar decoding method, the polar coding method and the polar decoding method provided in this application can achieve an effect of reducing a bit rate. A simulation result indicates that the method has better performance.
