<P>PROBLEM TO BE SOLVED: To prevent deterioration of communication quality of signals received by a communication device. <P>SOLUTION: A wireless base station 1 receives a plurality of signals transmitted from wireless terminals 2A to 2D. Next, the wireless base station 1 measures delay time of the plurality of received signals. Furthermore, when the measured delay time exceeds predetermined permissible time, the wireless base station 1 transmits a delay notification indicating that the signal is delayed to the wireless terminal which is the transmission source of the delayed signal and to any of the wireless terminals which are the transmission sources of the signals transmitted by using a subsequent time slot of the time slot used in the transmission of the delayed signal. Any of the wireless terminals 2A to 2D which has received the delay notification increases the transmission speed of the signal transmitted by using the time slot. <P>COPYRIGHT: (C)2010,JPO&INPIT |
