Method, communication device, processing device, and storage medium for performing channel encoding, and method, communication device, processing device, and storage medium for performing channel decoding

A communication device for performing channel encoding in a wireless communication system, the communication device comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations including:
• determining an information block input to channel encoding;
• encoding the information block based on a polar sequence QN-10={Q0, Q1, . . . , QN-1} to produce N encoded bits;
• performing rate matching on the encoded bits to produce rate-matched bits;
• and
• transmitting the rate-matched bits,
• wherein 0<=QNi<=N−1 is a bit index for i=0, 1, . . . , and N−1,
• wherein the polar sequence QN-10 is defined in ascending order of reliability W(QN0)<W(QN1)< . . . <W(QNN-1), W(QNi) being reliability of a bit index QNi,
• wherein N>1024,
• wherein a reliability order between bit indices 0 to 1023 in the polar sequence QN-10 is equal to a reliability order between bit indices 0 to 1023 in a predefined polar sequence Q0Nmax-1 with Nmax=1024, and
• wherein, from among bit indices greater than or equal to 1024 in the polar sequence QN-10, bit indices for which a partial order is to be evaluated satisfy W(QNx)<W(QNy) for at least QNx<QNy.
