<P>PROBLEM TO BE SOLVED: To suppress the influence on line capacity by feedback information to the minimum, without degradation of information transmission efficiency due to transmission of a pilot symbol. <P>SOLUTION: A delay dispersion-measuring section 272 uses a received signal to make a delay profile and measures delay dispersion indicative of dispersion of delayed waves. A movement speed-estimating section 274 estimates, based on variation of reception electric power of the pilot symbol, the movement speed of a mobile station apparatus which has transmitted the pilot symbol. An other-cell interference measuring section 276 uses the pilot symbol to measure an other-cell interference caused by a signal transmitted from a cell other than the cell to which the self apparatus belongs. A pilot pattern information generating section 278 generates pilot pattern information by selecting a pilot pattern which optimizes a location of the pilot symbol in a frame in response to the delay dispersion, movement speed and other-cell interference. <P>COPYRIGHT: (C)2010,JPO&INPIT |
