1. A method performed by a first device of a communication system comprising:
obtaining an estimated bit sequence based on signals received from a second device;
based on a decoding of the estimated bit sequence being unsuccessful, determining whether a specified condition for a code dimension is satisfied or not, the code dimension indicating a length of the estimated bit sequence;
based on the specified condition being satisfied, obtaining a modified bit sequence by inverting one bit in the estimated bit sequence, wherein a position of the one bit in the estimated bit sequence to be inverted is determined by the code dimension; and
performing a cyclic redundancy check (CRC) for the modified bit sequence.
