Abstract: The present disclosure provides an encoding method and apparatus, and relates to the field of communications technologies, to reduce an encoding latency and complexity, and the amount of computation of real-time construction. The encoding method includes: obtaining information bits; determining a puncturing pattern, where the puncturing pattern includes an element in a puncturing set and an element in a shortening set, and the puncturing set and the shortening set have no intersection set; and performing, by using the determined puncturing pattern, rate matching on data obtained after the information bits are encoded.

Abstract: A clock synchronization method, including: obtaining (S201), by a slave clock apparatus, a first time point at which a master clock apparatus sends first information, a second time point at which the slave clock apparatus receives the first information from the master clock apparatus, a third time point at which the slave clock apparatus sends first feedback information, and a fourth time point at which the master clock apparatus receives the first feedback information from the slave clock apparatus; then obtaining (S202) a first clock count offset based on the first time point, the second time point, the third time point, and the fourth time point; then obtaining (S206) a first clock frequency offset based on the first clock count offset; and finally adjusting (S207) a clock count step of the slave clock apparatus based on the first clock frequency offset.

Abstract: Embodiments of this application provide a data transmission method and related device. The method includes: A receive end receives data from a transmit end; and sends a first response message to the transmit end at a triggering moment of a first preset condition. The first response message comprises acknowledgement (ACK) or negative acknowledgement (NACK) determined based on a channel quality evaluation result obtained by the receive end after evaluating channel quality of a first channel of the transmit end. The first response message is used by the transmit end to determine, based on the ACK or NACK carried in the first response message, whether to resend the data. The receive end may estimate the channel quality in advance, to predetermine a data receiving status before the data is actually received, and return the channel quality to the transmit end at preset moments. This effectively shortens a data transmission delay.

Abstract: This application discloses a polar code-based interleaving method and apparatus, to resolve a problem existing in the prior art that when a code length is relatively long, an implementation process of reading a sequence obtained after random interleaving is relatively complex. The method includes: determining an interleaving matrix based on a target code length M of a polar code; and interleaving, based on the interleaving matrix, encoded bits obtained after encoding of the polar code, to generate interleaved bits.
