<p><P>PROBLEM TO BE SOLVED: To provide a means for carrying out air synchronization, in a frequency division duplex operation type base station device. <P>SOLUTION: This base station device 1b for executing communication with a terminal device 2b by frequency division duplex operation wherein the frequency of an up signal and that of a down signal are different from each other includes: a first reception part 11 for receiving an up signal from the terminal device 2b at the frequency f<SB>u</SB>of the up signal; a transmission part 13 for transmitting a down signal to the terminal device at the frequency f<SB>d</SB>of the down signal; a second reception part 12 for receiving a down signal from another base station device 1a at the frequency f<SB>d</SB>of the down signal; a synchronization error detection part 17 for detecting a synchronization error between the other base station device 1a and the own device 1b based on the down signal of the other base station device 1a received by the second reception part 12; and a correction part 18 for correcting the synchronization error based on the synchronization error detected by the synchronization error detection part 17. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
