    • PROBLEM TO BE SOLVED: To suppress the increase of a signaling amount while maintaining radio communication quality at a mobile station.SOLUTION: A relay station 200 includes: a receiver unit 220 for receiving a first radio frame FR transmitted from a base station 100; and a transmitter unit 230 for transmitting a second radio frame FS, including a downward data signal included in the received first radio frame FR, to a mobile station 300 existent in the zone of the own cell Cr of the relay station 200. On determination of a first identifier of a handover target cell Cb included in the first radio frame FR matching with a second identifier of the own cell Cr of the relay station 200 included in the second radio frame FS, and further the transmission timing of the first identifier coincident with the transmission timing of the second identifier, a time shift unit 256 in the relay station 200 shifts the transmission timing of the second radio frame FS to be transmitted by the transmitter unit 230, to make the transmission timing of the first identifier different from the transmission timing of the second identifier.
    • 解决的问题:在移动台维持无线通信质量的同时抑制信令量的增加。 解决方案:中继站200包括:接收单元220,用于接收从基站100发送的第一无线电帧FR; 以及发送单元230,用于将包括在接收的第一无线帧FR中的向下数据信号的第二无线帧FS发送到中继站200的自身小区Cr的区域中存在的移动台300.在确定 与第二无线帧FS中包含的中继站200的自身小区Cr的第二标识符匹配的第一无线帧FR中包含的切换目的地小区Cb的第一标识符,以及第一标识符的发送定时与第 第二标识符的发送定时,中继站200中的时移单元256将发送单元230发送的第二无线帧FS的发送定时移位,使得第一标识符的发送定时不同于发送 第二标识符的定时。 版权所有(C)2013,JPO&INPIT
