    摘要: A method for performing ranging by a mobile station in a communication system. The method includes transmitting a ranging sequence to a relay station; receiving an added signal of a reference sequence of the relay station and the ranging sequence, from the relay station; performing a correlation operation on each of the ranging sequence and the reference sequence in the added signal; estimating a time difference between the ranging sequence and the reference sequence depending on the correlation operation; and transmitting the signal to the relay station taking the time difference into account.

    摘要: Disclosed is a method for transmitting a signal in a communication system supporting multiple communication service modes. The base station includes at least one preamble generator for generating a preamble to which a sequence and a cell IDentifier (ID) of the base station are allocated, the sequence being one-to-one mapped to one communication service mode supportable by the base station. By the method, in mobile communication systems after the 3G communication system, it is possible to support multiple communication service modes optimized for multiple communication environments in a single communication system and to provide each mobile station with an optimum communication service mode for a specific communication environment of the mobile station.

    摘要: A method is provided for recognizing the frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where the transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another. The base stations transmit to a mobile station first information, including information about their frequency bandwidths at the same frequency position over a minimum frequency bandwidth with the same center frequency. The mobile station recognizes the presence of the base stations by comparing the first information from the base stations and detects the frequency bandwidth information in the first information.
