Abstract

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 is provided. The interleaving method includes determining sizes of a horizontal area and a vertical area of an interleaver memory, selecting a defined number of adjacent coded symbols in a same code block according to a modulation scheme, generating modulation groups in a vertical direction, sequentially writing the modulation groups in the horizontal area on a row-by-row basis, and sequentially reading the symbols written in the interleaver memory on a column-by-column basis.

Description

technical field [0001] The present invention relates to a method and device for sending data in the next generation mobile communication system. More particularly, the present invention relates to a method and apparatus for interleaving data in a mobile communication system. Background technique [0002] Regarding mobile communication systems, Orthogonal Frequency Division Multiple Access (OFDMA) and Single Carrier-Frequency Division Multiple Access (SC-FDMA) are being intensively studied as schemes for high-speed data transmission in wireless channels. [0003] Currently, the 3rd Generation Partnership Project (3GPP), which is a standardization organization for asynchronous cellular mobile communications, is studying the Long Term Evolution (LTE) system or the Evolved Universal Terrestrial Radio -UTRA) system. [0004] Multiple access schemes typically allocate and manage the time-frequency resources that will carry each user's data or control information respectively so ...
