    摘要： A cognitive radio communication terminal including a transmission processing unit to divide data by a quiet time slot that is allocated at a first point in time of a collision detection period, to transmit at least one portion of the divided data to a reception side, and a sensing unit to determine whether at least one of a feature information and an energy of another terminal is detected in a channel with the reception side during the quiet time slot of the first point in time. Where neither the feature information nor the energy of the other terminal is detected based on a determination of the sensing unit, the transmission processing unit transmits the remaining divided data.

    摘要： Provided is an interference aligning method and apparatus that does not perform full feed-forwarding in a hierarchical cell communication. A macro base station may generate respective transmission beamforming vectors of macro terminals to null interference channels to pico terminals and to remove interference among the macro terminals. The effective interference channels are based on reception beamforming vectors of the pico terminals. The macro base station may transmit, to a macro terminal, a feed-forward indicator (FFI) indicating a method of transmitting information associated with a reception beamforming vector of the macro terminal. The macro terminal may obtain information associated with the reception beamforming vector based on the FFI.

    摘要： A communication system performs an uplink communication and a downlink communication using respective radio resources that at least partially overlap each other in both time and frequency, which may cause interference to occur in at least one downlink terminal due to at least one uplink terminal. The at least one uplink terminal and the at least one downlink terminal may process the interference according to a rate split scheme, an interference control scheme, and the like. Interference occurring between at least one transmit antenna and at least one receive antenna of a base station may be processed according to an echo cancellation scheme and the like.
