    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： A system and method are provided for controlling a data rate in a communication system. A transmitter sets threshold values for classifying Modulation and Coding Scheme (MCS) levels. When receiving information about an MCS level desired to be used in the receiver, the transmitter sets an MCS level to be actually used in the receiver and transmits information about the set MCS level to the receiver. When detecting that the information is to be transmitted to the transmitter, the receiver computes instantaneous link capacity using a channel estimation result, sets an MCS level mapped to the instantaneous link capacity, and transmits information about the set MCS level to the transmitter. The receiver receives the information about the MCS level to be actually used from the transmitter.

    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： Provided are a spatial multiplexing apparatus and method in a Multiple Input Multiple Output (MIMO) system. The spatial multiplexing detection method includes estimating channels of a received signal, and sorting the estimated channels in descending order according to a scheme; generating a subsystem of a minimum unit by nulling an arbitrary channel among the sorted channels; performing a modified maximum likelihood (MML) in the subsystem of the minimum unit to calculate a number of transmission signal vectors; and calculating Euclidean distances of the number of the transmission signal vectors, and selecting a transmission signal vector having a minimum Euclidean distance. Accordingly, the receiver exhibits a performance level similar to a Maximum Likelihood (ML) and can obtain the complexity similar to successive interference cancellation (SIC).

    摘要： A method and apparatus for transmitting localized-type resource allocation information by a base station in a communication system. The base station transmits allocation information for localized-type resources using multiple mini-resource blocks. The mini-resource blocks are generated by dividing the localized-type resources into first localized-type resources for mini-resource block generation, and second localized-type resources, and dividing the first localized-type resources by a predetermined number.
