Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. An apparatus comprising:
a processor;
a non-transitory computer readable storage medium storing instructions that, when executed by the processor, cause the apparatus to performing operations including:
receiving, from another apparatus, a signal based on encodedbits, the encodedbits pro duced by encoding using a polar code, information bits and three parity check bits generated based on a subset of the information bits, and the three parity check bits generated based on a length-5 cyclic shift register, wherein the polar code is associated with a plurality of sub-channels, wherein the encodedbits are further produced by placing each of the information bits and the three parity check bits in a respective sub-channel of the plurality of sub-channels, and wherein the placing comprises:
shifting the length-s cyclic shift register for each sub-channel of the plurality of sub-channels, and:
for placing each of the information bits, performing an XOR operatio n with a respective information bit value of the information bits and a bit value of the length-5 cyclic shift register, or
for placing each of the three parity check bits, retrieving a respective parity checkbit value of the three parity check bits from the length-5 cyclic shift register; and
decoding the encoded bits.
