Method for polar coding in communication network

A device in a wireless communication network, comprising a processor and a memory storing program instructions for execution by the processor;

• wherein when executed by the processor, the program instructions cause the device to:
• obtain K information bits and a length M, wherein K, M are positive integers;
• generate a bit sequence, wherein the bit sequence has N bits, the N bits include the K information bits and a number J′ of parity check bits, wherein N≥K+J′ and J′≥1;
• encode the bit sequence, to obtain an N-bit encoded sequence;
• and
• rate match the N-bit encoded sequence, to obtain the rate matched sequence, wherein a length of the rate matched sequence is M;
• modulate the rate matched sequence, to obtain an output sequence;
• and
• wherein when M−K>192, one of the parity check bits is placed in a bit position of the bit sequence, and the bit position is determined according to reliabilities of bit positions in the bit sequence for placing the K information bits and the J′ parity check bits.

A non-transitory computer readable medium storing program codes thereon for execution by a processor in a communication device, wherein the program codes comprise instructions for:

• obtaining K information bits and a length M, wherein K, M are positive integers;
• generating a bit sequence, wherein the bit sequence has N bits, the N bits include the K information bits and a number J′ of parity check bits, wherein N≥K+J′ and J′≥1;
• encoding the bit sequence, to obtain an N-bit encoded sequence;
• rate matching the N-bit encoded sequence, to obtain the rate matched sequence, wherein a length of the rate matched sequence is M;
• modulating the rate matched sequence, to obtain an output sequence;
• outputting the output sequence;
• and
• wherein when M−K>192, one of the parity check bits is placed in a bit position of the bit sequence, and the bit position is determined according to reliabilities of bit positions in the bit sequence for placing the K information bits and the J′ parity check bits.
