摘要： A packet scheduling method using a cumulative distribution function. The scheduling method for use in a communication system including a plurality of MSs (Mobile Stations) and a central controller for assigning resources to individual MSs on the basis of a transmission rate associated with downlink channels fed back from the MSs, includes the steps of generating a uniform random variable of transmission rates of individual MSs; converting the uniform random variable into a scheduling priority; comparing the scheduling priority of each MS with each other; and assigning resources to a MS having the highest scheduling priority.

摘要： In a wireless communication system, a BS transmits first resource allocation information common to all MSs at every predetermined first time point of a first period, and transmits second resource allocation information dedicated to each of the MSs at every predetermined second time point of a second period shorter than the first period, within the first period. An MS receives the first resource allocation information at every first predetermined time point of the first period, and receives second resource allocation information dedicated to the MS at a second time point of the second period predetermined for the MS by analyzing the first resource allocation information.

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.

摘要： A scheduling method and system is disclosed that divides scheduling between a base station and a mobile station into scheduling between the base station and a relay station and scheduling between the relay station and the mobile station, and performs the divided schedulings. In a radio communication system that transmits a signal of a base station to mobile stations located on a border of a cell by using a relay station, the base station having multiple antennas receives phase information of the respective antennas from the relay station having multiple antennas, compensates for phases of the respective antennas, and transmits data through the phase-compensated antennas. The relay station transmits only channel quality information of the mobile station, which has a high possibility of being selected by the base station among channel quality information of the mobile stations that belong to the relay station, to the base station.
