| 20090161603 | WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD - A wireless communication apparatus is capable of improving communication efficiency by reducing the amount of control information transmitted. A channel quality information extraction section extracts CQI's from a received signal. An allocation control section allocates subcarriers every communication terminal apparatus and selects a modulation scheme in such a manner that required transmission rate is satisfied for each communication terminal apparatus based on required transmission rate information etc. and CQI's for communication terminal apparatus of each user. A required subcarrier number determining section decides the number of subcarriers allocated every communication terminal apparatus in such a manner as to satisfy the required transmission rate for each communication terminal apparatus based on required transmission rate information etc. of communication terminal apparatus of each user. A required subcarrier number information generating section generates information for the number of subcarriers allocated every communication terminal apparatus. A subcarrier allocation section allocates packet data to selected subcarriers. Modulating sections adaptively modulate packet data allocated to each subcarrier. | 06-25-2009 |
| 20090258600 | WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD - A wireless communication apparatus is capable of increasing data capacity that can be transmitted and reducing power consumption by reducing the amount of control signal to be transmitted, and capable of increasing system capacity by reducing interference with respect to other wireless communication apparatuses. | 10-15-2009 |
| 20090270052 | APPARATUS AND METHOD FOR RADIO TRANSMISSION - 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. | 10-29-2009 |
