    摘要： A method and system for using frequency resources in a communication system are provided. In the method and system, a total frequency band is divided into at least two frequency subbands and there is a guard interval between frequency subbands. A first frequency subband includes a TDD UL frequency subband and a TDD DL frequency subband. A second frequency subband includes an FDD UL frequency subband. A BS sets a frequency band between the TDD UL frequency subband and an FDD UL frequency subband as an additional UL frequency subband, and receives a signal from an MS in the additional UL frequency subband.

    摘要： A method for providing a service in a communication system is provided. A Base Station (BS) supporting a plurality of communication service modes allocates communication resources for each of the plurality of communication service modes according to a ratio determined in accordance with a communication service mode preferred by a terminal. The BS transmits a combination of resources allocated for each of the plurality of communication service modes to the terminal. The communication service mode preferred by the terminal is determined using at least one of channel condition of the terminal, moving velocity, preferred communication mode, required performance, billing system, and user preference.

    摘要： Disclosed is a space-time coding apparatus and method to flexibly adjust diversity/multiplexing orders in a multiple-antenna system. The transmitting apparatus for the multiple-antenna system includes a space-time code controller, an encoder, a demultiplexer, and a space-time encoder. The space-time code controller generates space-time codes by determining bases according to a multiplexing order required by a receiver. The encoder modulates and encodes data destined for the receiver in accordance with a predetermined modulation level. The demultiplexer demultiplexes data received from the encoder in order to transmit the data through at least one antenna. The space-time encoder space-time-codes the demultiplexed data using the space-time codes.

    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.
