Title:
APPARATUS AND METHOD FOR ENCODING AND DECODING USING POLAR CODE IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/190281
Kind Code:
A1
Abstract:
A pre-5th generation (5G) or 5G communication system supports higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE) is provided. A method for operating a first device in a wireless communication system includes generating a first bit sequence, generating a second bit sequence including at least one of the first bit sequence, at least one cyclic redundancy check (CRC) bit, at least one frozen bit, or at least one parity check (PC) bit, generating a transmission bit sequence by performing a polar encoding and a rate matching for the second bit sequence, and transmitting, to a second device, the transmission bit sequence. A length of the transmission bit sequence is equal to or greater than a sum of a length of the first bit sequence, a number of the at least one CRC bit and a number of the at least one PC bit.
