Abstract: This application provides an uplink signal synchronization method and a communication apparatus. A terminal device receives first indication information, where the first indication information indicates first duration, the first duration is validity duration of synchronization information, and the synchronization information is used for uplink signal synchronization. The terminal device performs the uplink signal synchronization based on second indication information within the first duration that is after reception of the second indication information, where the uplink signal synchronization includes time domain offset compensation and/or frequency domain offset compensation, and the second indication information indicates the synchronization information. This can improve communication reliability.

Abstract: A low density parity check (LDPC) channel encoding method is used in a wireless communications system. A communication device encodes an input bit sequence by using an LDPC matrix, to obtain an encoded bit sequence for transmission. The LDPC matrix is obtained based on a lifting factor Z and a base matrix. The base matrix may be one of eight exemplary designs. The encoding method can be used in various communications systems including fifth generation (5G) telecommunication systems, and can support various encoding requirements for information bit sequences with different code lengths.

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 bandwidth part switching method, is applicable to a non-terrestrial network (NTN) to implement BWP switching based on multi-color frequency-division multiplexing. In the method, a terminal device may report, in a second BWP to a network device, an index of a first SSB whose signal quality is greater than or equal to a first threshold in one or more SSBs in a first BWP, and switch from the second BWP to a third BWP. The one or more SSBs correspond to at least one BWP other than the first BWP, and the third BWP is in the at least one BWP and corresponds to the first SSB. After receiving the index of the first SSB in the second BWP, the network device determines the third BWP, and performs service data transmission with the terminal device in the third BWP.

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.
