Abstract
According to certain embodiments, a method by a transmitter is provided for adaptively generating precoder bits for a Polar code. The method includes acquiring at least one configuration parameter upon which a total number of precoder bits depends. The at least one configuration parameter comprising at least one of an information block length K, a code block length N, and/or a code rate R=K/N. The total number of precoder bits is determined, and the precoder bits for a code block are generated according to the determined total number of precoder bits. The precoder bits are placed within the code block.

A method by a transmitter for polar encoding an uplink control message, the method comprising:
- acquiring a length of a sequence of information bits of the unencoded uplink control message and a length of a sequence of coded bits of the polar encoded uplink control information message;
- determining a number of CRC bits, the number of CRC bits depending upon the length of the sequence of information bits and the length of the sequence of coded bits;
- generating the CRC bits according to the determined number of CRC bits;
- attaching the CRC bits to the information bits;
- and
- encoding, by the polar encoder, the information bits and the CRC bits with a Polar code.
A transmitter comprising a polar encoder for polar encoding an uplink control message, the transmitter comprising:
- at least one processor configured to:
- acquire a length of a sequence of information bits of the unencoded uplink control message and a length of a sequence of coded bits of the polar encoded uplink control information message;
- determine a number of CRC bits, the number of CRC bits depending upon the length of the sequence of information bits and the length of the sequence of coded bits;
- generate the CRC bits according to the determined number of CRC bits;
- attach the CRC bits to the information bits;
- and
- encode, by the polar encoder, the information bits and the CRC bits with a Polar code.
