Abstract: An apparatus and a method for cooperative diversity in a wireless communication system are provided to alternatively transmit data to two repeaters by enabling a source node to perform an SM(Superposition Modulation) or an HM(Hierarchical Modulation), thereby requiring cooperative diversity while reducing the amount of resources. If information bits exits, a source node(400) hierarchical-modulates B and C after hierarchical-modulating A and B. Then, the source node hierarchical-modulates C and D. During odd-numbered time slots, modulated symbols are transmitted to a first repeater(410). During even-numbered time slots, the modulated symbols are alternatively transmitted to the second repeater(420), and the second repeater demodulates the received modulated symbols through a demodulator(412).

Abstract: 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.
