摘要： A multi-cell communication system comprises at least a first base station and first terminal and a second base station and second terminal. When the first and second base stations need to perform interference control, the first terminal may relay a message related to the interference control between the first base station and the second base station. That is, the first terminal may transfer a message related to the interference control from the first base station to the second base station, and a message related to the interference control from the second base station to the first base station. As such, the first base station and the second base station can transmit/receive messages that are for performing interference control via the first terminal.

摘要： A method for selecting an antenna in an orthogonalized spatial multiplexing system. Upon receipt of at least one symbol from a transmitter via multiple receive antennas, a receiver decodes each of the received symbols; determines a rotation angle between the received symbols, and selects an optimal subset of transmit antennas using a distance between vectors of the decoded symbols; generates feedback information including the determined rotation angle and the selected optimal subset, and transmits the generated feedback information to the transmitter. Upon receipt of the feedback information, the transmitter beam-forms an antenna corresponding to the optimal subset depending on the received feedback information, and transmits a data symbol to the receiver. The receiver detects each of data symbols received from the transmitter.
