TRANSMISSION / RECEPTION APPARATUS IN MOBILE COMMUNICATION SYSTEM AND METHOD

PROBLEM TO BE SOLVED: To provide the mobile communications system capable of preventing performance degradation during a channel-decoding process. SOLUTION: A transmitter of the mobile communications system includes a channel-coding unit which performs a channel coding after inputting a bit string and outputs an information bit string and a plurality of parity bit strings by performing the channel coding. The transmitter includes a bit interleaver, which inputs a plurality of parity bit strings and performs bit interleaving to a plurality of parity bit strings so as to prevent a repetition period, where the parity bit has in each parity bit string from matching a puncturing pattern for a rate matching and a rate matching unit which inputs the information bit string and the parity bit strings that the bit interleaving is performed and performs rate matching. A total number of bits, that constitutes the information bit string outputted by the rate matching and the parity bit strings, is the number of bits that can be transmitted through an assigned physical channel.
