摘要： A method of transmitting secret information in a transmitting end and a method of receiving secret information at a receiving end, based on multi-input multi-output (MIMO) multiplexing using antennas, are provided. The method of transmitting includes selecting one or more indices of the secret information that correspond to at least one receiving antenna among receiving antennas, and mapping the one or more indices to an information vector. The method of transmitting further includes precoding the information vector based on channel information between transmitting antennas and the receiving antennas, and beamforming the precoded information vector, using the transmitting antennas.

摘要： The invention relates to a base station in a wireless communication system comprising a mobile station and the base station. The base station comprises a CSI receiving unit configured to receive Channel State Information (CSI) of a first channel between the base station and a first mobile station from the first mobile station, the first mobile station being located in a cell where the base station belongs, a PMI receiving unit configured to receive a Precoding Matrix Index (PMI) which is determined by a second mobile station based on a second channel between the base station and the second mobile station, the second mobile station being located in an adjacent cell and a precoder configured to design a precoding vector based on the CSI and the PMI.

摘要： A method and apparatus of controlling resources of a femto base station for protecting a macro terminal and controlling interference among femto base stations are provided. The femto base station or a gateway of the femto base station may allocate resource blocks of a femto cell based on a silencing resource block for protecting the macro terminal. Also, the femto base station or the gateway of the femto base station may allocate the resource block of the femto cell based on a relative location between the macro base station and the femto base station and a victim macro terminal. The femto base station or the gateway of the femto base station may allocate the resource block of the femto cell based on a resource block used by a neighboring femto base station.

摘要： Provided is a method and apparatus for distributed transmission power control in a wireless network. The method and apparatus for distributed transmission power control may substantially maximize a minimum value of a transmission rate of each transmitter by controlling a transmission power of each transmitter. The transmission power may be controlled so that transmission rates of transmitters are substantially identical to each other. If the transmission rate is less than a requested transmission rate, the method and apparatus may change a resource of a transmitter that uses a substantially maximum power.
