Encoding and decoding techniques

A method for communication, comprising:

• decoding a first set of bits from a first transmission, the first set of bits comprising a first subset of bits including first cyclic redundancy check (CRC) information, the first set of bits further comprising a second subset of bits including second CRC information, the first subset of bits being encoded on a first set of Polar code sub-channels associated with a first Polar code sub-channel quality and the second subset of bits being encoded on a second set of Polar code sub-channels associated with a second Polar code sub-channel quality that is lower than the first Polar code sub-channel quality;
• and
• when a result of the decoding of the first set of bits is incorrect:
• receiving a second transmission that includes a second set of bits comprising the second subset of bits including the second CRC information from the first transmission;
• decoding the second set of bits;
• and
• decoding at least a portion of the first set of bits using the decoded second set of bits.

An apparatus for communication comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors configured to execute the processor-executable code to cause the apparatus to:
• encode a first set of bits to provide an encoded first set of bits, the first set of bits comprising a first subset of bits including first cyclic redundancy check (CRC) information, the first set of bits further comprising a second subset of bits including second CRC information, the first subset of bits being encoded on a first set of Polar code sub-channels associated with a first Polar code sub-channel quality and the second subset of bits being encoded on a second set of Polar code sub-channels associated with a second Polar code sub-channel quality that is lower than the first Polar code sub-channel quality;
• transmit the encoded first set of bits in a first transmission;
• receive an indication of an unsuccessful decoding of the encoded first set of bits;
• and
• in response to the received indication:
• encode a second set of bits comprising the second subset of bits including the second CRC information from the first transmission;
• and
• transmit the second set of bits in a second transmission.
