METHOD AND APPARATUS FOR INTERLEAVING DATA IN MOBILE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an interleaving method to which time-first-mapping is applied for a plurality of channel-coded and rate-matched code blocks considering a modulation scheme in a mobile communication system.SOLUTION: The interleaving method includes the steps of determining sizes of a horizontal area and a vertical area of an interleaver memory, selecting a prescribed number of adjacent coded symbols in the same code block according to a modulation scheme, constructing modulation groups in a vertical direction, sequentially writing the modulation groups in the horizontal area row by row, and sequentially reading the symbols written in the interleaver memory column by column.
