Method and apparatus for encoding in wireless communication system

This disclosure relates to LTE (Long Term Evolution) and 4G (4 The present invention is to maximize the adaptive transmission performance by designing the drilling sequence and the repeated sequence in the sequence individually optimized. When the operation method of a transmitting apparatus for adaptive transmission of a codeword according to an embodiment of the present invention, pole code requires a process with the bit repetition by using the (polar code) generating a code word (code words), repeat comprising the step of transmitting a packet including at least one codeword that is indicated by the sequence, the repeat sequence is determined based on at least one of a polarization channel and the channel quality information.
