Polar Code Segment Encoding Method and Communication Device

A communication device, comprising at least one memory and at least one processor, wherein the at least memory is coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:

• performing segmentation of to-be-encoded information bits of a length N into respective quantities of different types of segments, wherein:
• the different types of segments are among (b−a+1) types of segments that correspond to (b−a+1) different segment code lengths, wherein
• the (b−a+1) types of segments comprise a minimum-length segment that has the minimum segment code length of 2{circumflex over ( )}a among the (b−a+1) types of segment code lengths, and a maximum-length segment that has the maximum segment code length of 2{circumflex over ( )}b among the (b−a+1) types of segment code lengths, and
• the respective quantities of the different types of segments are determined based on the length N of the to-be-encoded information bits 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, and
• performing polar code encoding on the respective quantities of the different types of segments of the to-be-encoded information bits to obtain encoded output bits.
