    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.

    摘要: A communication method for at least one mobile station that includes a target mobile station that performs a Cooperative Multi-Point (CoMP) communication with at least two base stations, is provided. The communication method includes determining a beamforming vector used by the at least two base stations based on channel vectors and at least one channel matrix such that a signal-to-leakage-plus-noise-ratio (SLNR) for a target antenna from among antennas of a target mobile station is maximized. A Cholesky factorization may be used to determine an optimal beamforming vector with a low complexity.

    摘要: A method and apparatus for controlling transmission power in a wireless network area is provided. A target base station may control transmission power in cooperation with a neighboring base station and, thus, a satisfaction with a Quality of Service (QoS) of target terminals may be improved. Additionally, the target base station may determine whether to control the transmission power in cooperation with the neighboring base station, based on a possible improvement in satisfaction with the QoS of the target terminals.
