    • A method and an apparatus for transmitting/receiving data in a communication system using a repeater are provided to use different frequency re-usage rate in an inner region and an outer region of a cell, and provide an adaptive HDD scheme between a base station and a repeater according to the location of a terminal. When a terminal 3(316) and a repeater 1(314) located in an inner region(310) of a cell communicate with a base station(312), they use the first duplexing method of transmitting/receiving data by using a TDD duplexing scheme in a frequency band 'A'. A terminal 1(302) and a terminal 2(304) located at an outer region(300) of the cell communicate with the base station via the repeater 1(314) or directly communicate with the base station. In this case, the terminal 2 and the repeater 1 communicate by using the second duplexing method of transmitting/receiving data by using a TDD duplexing scheme at a frequency band 'B'. When the terminal 1 located at the outer region and the base station directly communicate, they use the third duplexing scheme of using an FDD scheme in which the frequency band 'B' is used in an uplink interval and the frequency band 'A' is used in a downlink interval.
    • 提供一种在使用中继器的通信系统中发送/接收数据的方法和装置,以便在小区的内部区域和外部区域中使用不同的频率再利用率,并且在基站和 根据终端的位置的中继器。 当位于小区的内部区域(310)的终端3(316)和中继器1(314)与基站(312)通信时,它们使用通过使用TDD双工来发送/接收数据的第一双工方法 方案在频带“A”。 位于小区的外部区域(300)的终端1(302)和终端2(304)经由中继器1(314)与基站通信,或者直接与基站通信。 在这种情况下,终端2和中继​​器1通过使用在频带“B”处的TDD双工方式来发送/接收数据的第二双工方法进行通信。 当位于外部区域的终端1和基站直接通信时,它们使用使用在上行链路间隔中使用频带“B”并使用频带“A”的FDD方案的第三双工方案 在下行链路间隔。
