Classification: CPC H | IPC H

Claim 8:
9. A receiver in a communication system, the receiver comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive a signal corresponding to a plurality of values from a transmitter;
identify a length of reception bits;
determine a size of a mother code for a polar decoding based on the length of the reception bits, a maximum size of the mother code, and a minimum size of the mother code;
perform a de-rate-matching of the plurality of values based on the length of the reception bits and the size of the mother code, wherein the size of the mother code is same as a codeword; and
obtain information bits by the polar decoding based on de-rate-matched values corresponding to the codeword,

wherein in case that the length of the reception bits is larger than the size of the mother code, at least a part of the plurality of values is repeated in the plurality of values,
wherein in case that the length of the reception bits is smaller than the size of the mother code, at least a part of the reception bits is punctured for the plurality of values,
wherein the minimum size of the mother code is a minimum supportable size among a set of a plurality of supportable sizes of the mother code, and wherein the plurality of supportable sizes of the mother code correspond to powers of 2.
