摘要： A method for reducing inter-cell interference (ICI) in a mobile communication system controls transmission signal power of an uplink signal from a terminal based on signal power measurement for a signal received from a base station of a neighboring cell. A terminal receives a signal from a base station of a neighboring cell via a wireless channel, measures a channel response against a threshold value across an applicable frequency band by using the received signal, determines a transmission signal power for each frequency band used for data transmission based on the measured channel response, and transmits data to a home cell base station according to the transmission signal power for each frequency band. The terminal may measure a channel response based on signals received from multiple base stations in multiple neighboring cells, and may also evaluate signal power of a signal transmitted from the home cell.

摘要： A method for controlling inter-cell interference (ICI) in a mobile communication system by transmitting uplink control information from a base station in a home cell to a terminal of a neighboring cell based on ICI amount information measured at the base station. The ICI control method includes receiving an uplink signal at a base station and extracting inter-cell interference amount information from the uplink signal, generating uplink control information based on the extracted inter-cell interference amount information, and transmitting the uplink control information to a terminal in a neighboring cell. The terminal schedules an uplink resource including selecting frequency bands for an uplink signal by referring to the uplink control information.

摘要： A Multiple-Input Multiple-Output data transmission system includes access stations and an access point having multiple receive antennas. An access point has a minimum contention window size decision unit to determine a minimum contention window size based on the number of receive antennas and a number of access stations, a broadcasting unit to broadcast the determined minimum contention window size to the access stations, and a receiver to receive data from the access stations in a contention window that is calculated based on the minimum contention window size. An access station receives the minimum contention window size from the access point, determines a first contention window size based on the minimum contention window size, and transmits data to the access point within the first contention window. If the transmission fails, the access station determines a second contention window size and retransmits the data in the second contention window.

An access point may include a receiver to receive channel measurement signals from stations using a plurality of receive antennas; a channel estimation unit to generate channel state matrices with respect to wireless channels formed from the stations to the receive antennas using the channel measurement signals; and a scheduler to select at least one transmitting station from the stations by considering the channel state matrices and a number of the receive antennas. The receiver may receive a data stream from the selected transmitting stations. Stations receive identifiers corresponding to transmitting stations and/or transmitting antennas to identify stations or antennas for transmitting data streams to the access point.
