1. A method for multiplexing a control information stream, and a data information stream comprised of one or more systematic bit symbols and one or more non-systematic bit symbols, the method comprising: mapping the data information stream to a resource area, so that the systematic bit symbols are not mapped to a specific resource area where the control information stream is to be mapped; and mapping the control information stream to the specific resource area, wherein the mapping the data information stream to the resource area includes mapping the non-systematic bit symbols to a first resource area including the specific resource area out of the resource area, and mapping the systematic bit symbols to a second resource area except for the first resource area out of the resource area by a predetermined method, and wherein the predetermined method includes relatively shifting at least a part of the systematic bit symbols within the second resource area by unit of determined symbols.
