Rate matching and bit freezing for systematic polar codes

A method for wireless communication by a transmitter, comprising:

• obtaining an input sequence including a set of information bits and a set of frozen bits, the set of information bits associated with a set of information bit locations that satisfies a systematic encoding condition in accordance with a rate matching mode;
• encoding the input sequence using a systematic polar encoder to obtain a systematic polar code that includes a first sequence of coded bits;
• performing a rate matching operation on the first sequence of coded bits in accordance with the rate matching mode to produce a second sequence of coded bits associated with the systematic polar code;
• and
• transmitting the second sequence of coded bits associated with the systematic polar code in accordance with the rate matching mode.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a transmitter, cause the transmitter to:
• obtain an input sequence including a set of information bits and a set of frozen bits, the set of information bits associated with a set of information bit locations that satisfies a systematic encoding condition in accordance with a rate matching mode;
• encode the input sequence using a systematic polar encoder to obtain a systematic polar code that includes a first sequence of coded bits;
• perform a rate matching operation on the first sequence of coded bits in accordance with the rate matching mode to produce a second sequence of coded bits associated with the systematic polar code;
• and
• transmit the second sequence of coded bits associated with the systematic polar code in accordance with the rate matching mode.
