Radio communication system, method, device and computer readable medium including first and second receiving signals respectively allocated to first and second overlapping subcarriers

Abstract

A communication device comprising at least a receiver and a demodulator. The receiver receives first receiving signals and second receiving signals, wherein the first receiving signals are allocated to a first set of subcarriers composed of two or more continuous subcarriers, the second receiving signals are allocated to a second set of subcarriers composed of two or more continuous subcarriers, and at least a portion of the second set of subcarriers overlaps a portion of the first set of subcarriers in a time frame. The demodulator configured to detect the second receiving signals transmitted using one or more subcarriers from receiving signals including the first receiving signals and the second receiving signals, wherein the one or more subcarriers are subcarriers such that the first set of subcarriers overlap the second set of subcarriers, and the demodulator being demodulates the first receiving signals.
