Abstract:
Radio transmission is performed even to a communication party whose bandwidth that can be used for transmission and reception is limited without having an influence of an offset of a DC component. A radio transmitter applied to an OFDMA communication system in which a plurality of different terminals performs communication using OFDM signals at the same time that includes a mapping part that allocates transmission power to each subcarrier, and also selects a subcarrier to which minimum power of the transmission power to be allocated is allocated and modulates transmission data in units of communication slots to output the modulated data; and a transmission part for transmitting radio signals including the modulated data using each of the subcarriers.

Claim (Index 1):
A first communication apparatus configured to receive OFDM signals by using at least some of a plurality of frequency sub-channels on a frequency band without a center subcarrier positioned in a center frequency of the frequency band, each of the OFDM signals comprising OFDM symbols for a first period and OFDM symbols for a second period, the first communication apparatus comprising:\n a receiving circuit configured for receiving the OFDM signals from a second communication apparatus by using a plurality of subcarriers allocated among an even number of contiguous frequency sub-channels, wherein the even number comprises at least an even number smaller than a number of the plurality of frequency sub-channels on the frequency band; a processing circuit configured for:\n de-modulating data from each of the OFDM symbols of the first period in which data is not allocated to a first subset of subcarriers of the plurality of subcarriers positioned in respective centers of frequency sub-channels among the even number of the contiguous frequency sub-channels, and \n de-modulating data from each of the OFDM symbols of the second period in which data is not allocated to a second subset of subcarriers of the plurality of subcarriers positioned in a center of a frequency band of the even number of the contiguous frequency sub-channels for the second period, the unused subcarrier being in a center between contiguous frequency sub-channels, in which data is allocated to the second subset of subcarriers positioned in respective centers of frequency sub-channels among the even number of the contiguous frequency sub-channels, \n wherein the data for reception in the first period to be allocated to the first subset of subcarriers of the plurality of subcarriers that are allocated among the even number of the contiguous frequency sub-channels comprises data representing control information, wherein each of the frequency sub-channels has a bandwidth of 20 MHZ and comprises 64 subcarriers, wherein the control information comprises information about the second period and indirectly indicating positions of subcarriers to which data is not allocated, wherein the positions of the plurality of subcarriers are known mutually between the first communication apparatus and the second communication apparatus based on the information indirectly indicating the subcarrier positions to which data is not allocated, wherein the information indirectly indicating the subcarrier positions to which data is not allocated includes information indicating a frequency bandwidth of the OFDM symbols for the second period.
