    Abstract: A coding method and apparatus are provided. The method includes: obtaining a to-be-coded sequence whose length is N, after an information bit is placed at an information bit position, wherein first preset bits are placed at shaping bit positions in a first position sequence, and shaping bit positions whose corresponding bits after polar coding belong to a same subcode of inner code belong to a same group; performing outer code coding on the to-be-coded sequence, to obtain a first outer code sequence whose length is N, based on which first outer code codeword bits corresponding to shaping bit position groups are obtained; obtaining a target outer code sequence based on the first outer code sequence and the first outer code codeword bits; and performing inner code coding on the target outer code sequence, to obtain and output a coded sequence. Probability amplitude shaping (PAS) coding latency can be reduced.

    Abstract: This application provides a TA determining method and apparatus for a terminal device. After receiving a TA adjustment parameter sent by an access network device and determining that a TA of the terminal device needs to be adjusted, the terminal device determines a TA scaling factor, a subcarrier spacing parameter, and a first TA, to jointly adjust the first TA to obtain a second TA. ATA adjustment parameter k is added when the terminal device determines the second TA, so that an adjustable range of the TA is larger. Therefore, the TA may be applied to determining the TA of the terminal device when the terminal device communicates with a satellite base station. In this way, the terminal device can adjust the TA when movement of a device is caused by both the terminal device and the satellite base station.

    Abstract: Embodiments of this application provide a wireless communication method and an apparatus. The method includes: A first communication apparatus receives first information, where the first information indicates a determining threshold of a parameter in a first parameter set, and the first parameter set includes at least one of the following parameters: location information, delay information, a timing advance rate, a rate of the timing advance rate, a Doppler value, a Doppler rate, and remaining coverage time. The first communication apparatus determines, based on the first information, whether an access condition is met, and performs random access when the access condition is met. This avoids a random access failure in a current cell and re-access in a next cell due to random access performed when the condition is not met.
