METHOD AND DEVICE FOR TRANSFERRING DATA, METHOD AND DEVICE FOR EXTRACTING DATA, COMPUTER PROGRAM, AND SIGNAL

摘要

PROBLEM TO BE SOLVED: To use a full frequency bandwidth efficiently at a base station.

SOLUTION: A method and a device transfer data to a second telecommunication device through a telecommunication network using multiple carrier frequencies by a first telecommunication device. The first telecommunication device maps the data on first carrier frequencies of plural consecutive groups of first carrier frequencies, (each group of first carrier frequencies being spaced from the next group of first carrier frequencies by a second carrier frequency, at least two second carrier frequencies being carrier frequencies which are susceptible to the demodulation carrier frequency of the second telecommunication device), and transfers the mapped data to the second telecommunication device.
