摘要： In a resource allocation method in a multicarrier-based mobile communication system that includes base stations and supports multiple access of a plurality of terminals identified using codes, the service area of each base station is divided into at least two virtual cells having different radii about the base station, and resources are actively allocated to terminals located in the service area according to distribution of the terminals in the virtual cells. The service area is divided into two virtual cells based on the received signal strengths of the terminals for a specific subchannel, and the specific subchannel is allocated to one terminal or at most two terminals according to distribution of the terminals in the virtual cells.

摘要： A resource allocation method in a wireless communication system for providing a communication service in a given system frequency band to access terminals (ATs) within a broad-band service area around an access point (AP) and to ATs within a narrow-band service area having a radius larger than the radius of the broad-band service area. In the resource allocation method, the system frequency band is divided into a Time Division Duplexing (TDD) interval and a Frequency Division Duplexing (FDD) interval in time, and the TDD interval and the FDD interval are defined as TDD resources and FDD resources, respectively. The TDD resources are allocated to an AT within the broad-band service area, and the FDD resources are allocated to an AT within the narrow-band service area.

摘要： Disclosed is a hybrid wireless communication system and a communication method in the system. The system supports time and frequency division duplexing modes and includes a base station having a cellular communication range based on a cellular mode and mobile stations within the cellular communication range. The base station divides each available frequency resource into frames for communication, and each frame switches between a real-time service mode and a non-real-time service mode at a switching time within the frame. Communication is performed with the mobile stations within the cellular communication range via at least one of an uplink and a downlink in the real-time service mode of each frame according to the frequency division duplexing mode. Communication is performed with the mobile stations via the uplink and the downlink in the non-real-time service mode of each frame according to an ad hoc mode based on the time division duplexing mode.

摘要： Provided is a multiple-input multiple-output (MIMO) data transmission method. A transmitter generates a transmission symbol by adding a parity symbol to a predetermined number of data symbols, generates a preprocessed symbol by multiplying the predetermined number of transmission symbols by a preprocessing matrix in units of blocks, selects a transmission antenna associated with a non-zero transmission symbol among preprocessed transmission symbols constituting the preprocessed symbol, and transmits the preprocessed symbol via the selected transmission antenna. A receiver receives a signal transmitted from the transmitter, estimates a preprocessed symbol and a transmission antenna index from the received signal, and restores the transmission symbols using the estimated preprocessed symbol and transmission antenna index.
