<P>PROBLEM TO BE SOLVED: To provide a radio communication device which performs high-speed communication while saving frequency to be used in accordance with the amount of transmission data. <P>SOLUTION: The radio communication device divides transmission data and transmits the divided transmission data in parallel via a plurality of (n) radio channels. The radio communication device comprises a determination unit 10 which determines the number of radio channels such that the number of radio channels becomes the highest value and a relative ratio of frequency utilization efficiency becomes greater than a threshold value, based on the relative ratio of frequency utilization efficiency calculated for each of the various numbers of radio channels used at the time of transmitting transmission data having a certain data amount, and transmission units 19, 20, and 21 for dividing the transmission data by the determined number of radio channels and transmitting the transmission data using that number of radio channels . <P>COPYRIGHT: (C)2012,JPO&INPIT |
