<P>PROBLEM TO BE SOLVED: To reduce interference by a frequency hopping scheme in combination with the FFR scheme. <P>SOLUTION: A frequency hopping pattern 600 is generated by dividing a portion of frequency into plurality of sub-bands 602 to 612, dividing a portion of time into plurality of sectors each having the divided sub-band, each sector comprising the divided sub-bands, designating one of the divided sub-band 614 to 624 within one of the sectors as a restricted sub-band 670, and allocating a location of the sub-band designated as the restricted sub-band. <P>COPYRIGHT: (C)2013,JPO&INPIT |
