Abstract: Embodiments of this application provide an encoding and decoding method and device in wireless communications between network devices and user equipment. The encoding method includes: obtaining, by a transmit end, a post-polar-encoding data length corresponding to to-be-encoded data; segmenting, by the transmit end, the to-be-encoded data into at least one code block based on the post-encoding data length and a preset threshold; and performing, by the transmit end, polar encoding on each code block, and transmitting encoded data to a receive end. The embodiments of this application avoid a data transmission performance loss caused by an excessive quantity of segments.

Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.
