Abstract: This application discloses a method: determining, based on a length of to-be-encoded information bits and a code rate, a code length N after encoding; determining, based on N, a minimum segment code length, and a maximum segment code length, a reserved segment quantity of each type of segments in segments of b−a+1 types of segment code lengths and a reserved code length corresponding to N, where the minimum segment code length is 2{circumflex over ( )}a, and the maximum segment code length is 2{circumflex over ( )}b; determining a segment quantity of each type of segments based on N, the reserved code length, a segment code length of each type of segments, and the reserved segment quantity of each type of segments, where N corresponds to S segments, and a segment code length of an ith segment in the S segments is greater than or equal to a segment code length of an (i+1)th segment in the S segments.

Abstract: Methods, devices, and computer-readable storage media are disclosed. In an example method, segmentation of to-be-encoded information bits of a length N into respective quantities of different types of segments is performed. The different types of segments are among (b−a+1) types of segments that correspond to (b−a+1) different segment code lengths. The (b−a+1) types of segments comprise a minimum-length segment that has the minimum segment code length of 2{circumflex over ( )}a and a maximum-length segment that has the maximum segment code length of 2{circumflex over ( )}b. The respective quantities of the different types of segments are determined based on the length N and a code rate in an orderly manner, wherein the orderly manner comprises firstly determining a quantity of the maximum-length segments and lastly determining a quantity of the minimum-length segments. Polar code encoding is performed on the respective quantities of the different types of segments of the to-be-encoded information bits.
