Abstract:
1. A method for transmitting signals using a plurality of frequency allocation bands, each having a band size for allocation, the plurality of frequency allocation bands being managed by one specific layer above a physical layer, the method comprising: mapping a plurality of information units of the specific layer to a plurality of channel coding blocks, respectively; performing channel coding on the plurality of information units of the specific layer through the plurality of mapped channel coding blocks to produce a plurality of codewords; mapping the plurality of codewords to the plurality of frequency allocation bands; transmitting the plurality of codewords through the plurality of frequency allocation bands to which the plurality of codewords are mapped, wherein each of the plurality of codewords is mapped to at least one of the plurality of frequency allocation bands, and wherein the step of mapping the plurality of information units to the plurality of channel coding blocks includes mapping a first information unit and a second information unit to a first channel coding block producing a first codeword and a second channel coding block producing a second codeword, respectively; and re-mapping the first information unit to the second channel coding block when the first information unit is retransmitted.
