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

[0001] This application is a divisional application of an invention patent application with a filing date of October 2, 2008, an application number of "200880119332.4", and an invention title of "Method and device for interleaving data in a mobile communication system". technical field [0002] 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 [0003] Regarding mobile communication systems, as schemes for high-speed data transmission in wireless channels, Orthogonal Frequency Division Multiple Access (OFDMA) and Single Carrier-Frequency Division Multiple Access (SC-FDMA) are being intensively studied. [0004] Currently, the 3rd Generation Partnership Project (3GPP), the standardization organization for asynchronous cellular mobile communications, is res...
