<P>PROBLEM TO BE SOLVED: To make it possible not to cause inter-channel interference in dealing with a dead time occurring when transmission and reception are switched in the case both TDMA and OFDMA are used in combination. <P>SOLUTION: A control device generates a first allocation including designation of a communication device which transmits and receives data; if in the first allocation, there is a communication device supposed to switch transmission and reception in consecutive time slots of the same subcarrier, inserts a guard time between the consecutive time slots; detects two subcarriers which are included in a predetermined frequency range in the first allocation, about which at least a part of transmission periods of data overlap, and which have time slots having the difference in timing starting transmission of data being larger than a predetermined value; and adjusts timing to start transmission of the time slots by inserting a guard time which makes the difference of timing to start transmission of the time slots smaller than the predetermined value in the detected two subcarriers. <P>COPYRIGHT: (C)2013,JPO&INPIT |
