Abstract: Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.

Abstract: At a base station apparatus, known pilot signals for use in channel estimation are transmitted, and in addition thereto MCS pilot signals that are used to perform adaptive modulations respectively corresponding to a plurality of modulation schemes are multiplexed and output. A mobile station apparatus dispreads the respective MCS signals out of the multiplex signal, compares these to known symbols patterns, and sends the MCS pilot signals that show a matching relationship to the base station apparatus as a mobile station reception result. Upon receiving the mobile station reception result from the mobile station apparatus, the base station apparatus selects the modulation scheme of the optimum modulation level for the downlink signals. This configuration makes it possible to switch the modulation schemes in an accurate and simple way.

Abstract: A radio transmission apparatus performs communications with high transmission efficiency. In this apparatus, a modulator modulates data and outputs to a first spreader. A second modulator modulates data under a modulation scheme having a higher M-ary number than the first modulator and outputs the modulated data to a second spreader. The first spreader spreads the data and outputs the spread data to a frequency domain mapping section. The second spreader spreads the data and outputs the spread data to a time domain mapping section. A frequency domain mapping section maps chips with spread data on subcarriers in the frequency domain and outputs the data with chips mapped on subcarriers to an IFFT section. The time domain mapping section maps chips with spread data on subcarriers in the time domain and outputs the data with chips mapped on subcarriers to the IFFT section.

Abstract: Provided is a mobile communication system capable of obtaining a diversity effect even when a signal received by a relay station has an error in a corporate relay to which time space encoding is applied. In this mobile communication system, when S1 has no error and S2 has an error, a relay station (1) does not perform relay transmission at time t (Null) and relay-transmits S1* to a base station at time t+T. That is, in this case, the relay station (1) relay-transmits at time t+T only S1 to be transmitted at time t when no error is contained in either S1 or S2. Moreover, when S1 has an error and S2 has no error, the relay station (1) relay-transmits S2 at time t and does not perform relay transmission at time t+T (Null). That is, in this case, the relay station (1) relay-transmits only S2 to be transmitted at time t+T at time t if no error is contained in either S1 or S2.
