    摘要: 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.

    摘要: A wireless transmitting apparatus capable of improving the reception error rate of a wireless receiving apparatus. In the inventive apparatus, a channel estimating part (122) acquires a propagation path estimated value. A control part (113) determines whether an estimation precision of the acquired propagation path estimated value is equal to or greater than a predetermined level. A pre-equalization (PE) part applies PE based on the acquired propagation path estimated value to a transport signal if it is determined that the estimation precision is equal to or greater than the predetermined level. Otherwise, the pre-equalization (PE) part avoids the PE application to the transport signal. An RF part (117) transmits the transport signal to which PE has been applied, and transmits the transport signal for which the PE application has been avoided.

    摘要: A radio communication apparatus is disclosed that enables the influence of the feedback information on the channel capacity to be kept to the minimum without reducing the transmission efficiency of information by transmission of pilot symbol. In the apparatus, a delay dispersion measuring section (272) generates a delay profile using the received signal, and measures delay dispersion indicative of dispersion of delayed versions. A moving speed estimating section (274) estimates moving speed of a mobile station apparatus that transmits a pilot symbol based on the variation in reception power of the pilot symbol. An other-cell interference measuring section (276) measures other-cell interference caused by signals transmitted in cells except the cell to which the apparatus belongs. Corresponding to the delay dispersion, moving speed and other-cell interference, a pilot pattern information generating section (278) selects a pilot pattern such that placement of pilot symbol is optimal in a frame, and generates the pilot pattern information.

    摘要: Provided are a radio communication mobile station apparatus, a radio communication base station apparatus and a radio communication method, which make it possible to correctly switch between transmission modes for a PUSCH and a PUCCH while impeding signaling overhead from increasing. A transmission mode setting unit (107) detects an instruction given by a base station, the instruction indicating a multiplexing method for a PUSCH and a PUCCH. A trigger information reporting determination unit (108) performs threshold discrimination where PHR_pucch, which is calculated by PHR_control calculation unit (106), is compared with a threshold value that depends on the multiplexing method indicated by the instruction given by the base station. Specifically, in a TDM transmission mode, trigger information is reported if PHR_pucch>X1[dBm] is satisfied. On the other hand, in an FDM transmission mode, the trigger information is reported if PHR_pucch
