Publication number: 20240195527Abstract: 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.Type: ApplicationFiled: December 29, 2023Publication date: June 13, 2024Inventors: Shengchen DAI, Jiajie TONG, Zhan YU, Kai FU, Rong LI, Jun WANG
