    摘要: Provided is an outer loop power control apparatus and method for a signal transmitter in a communication system. The outer loop power control method includes determining a first setpoint of a kth frame according to whether or not an error occurs in a (k−1)th frame, updating a second setpoint of the kth frame with the first setpoint of the kth frame if a difference value between the first setpoint of the kth frame and a second setpoint of the (k−1)th frame is greater than a first reference value, and transmitting a transmit power control message to a signal receiver at the kth frame if the difference value between first setpoint of the kth frame and the second setpoint of the (k−1)th frame is greater than a second reference value.

    摘要: An apparatus and method for detecting a feedback signal in a multi-cell or multi-sector sector BS in a broadband wireless communication system are provided. A demodulator correlates each tile being sets of subcarriers carrying feedback information received from a serving sector/cell with each possible codeword and calculates the squares of the absolute values of the correlations of the tiles for each possible codeword. A first detection decider sums the squares for each possible codeword and determines whether to perform detection on the received feedback information. If it is impossible to detect the feedback information, a second detection decider receives feedback information from a target sector/cell, combines the feedback information received from the serving sector/cell and the target sector/cell, and determines whether to detect the combined feedback information.

    摘要: An apparatus and method for selecting at least two users to be serviced in SDMA in an SDMA wireless communication system are provided. All users are ordered according to a predetermined rule and all possible user combinations each having at least two users are created from the ordered users. An investigation limit number is set using the capacity of a jth user combination. Or a total investigation number is reduced by comparing the interference-reflected SNR decrements of users with an investigation threshold. Therefore, the computation volume for selecting SDMA users is decreased.

    摘要: A method for transmitting a frame comprised of a plurality of slots over a dedicated control channel in a duration where there is no transmission message from a mobile station to a base station. Each slot in the frame is comprised of a first slot duration and a second slot duration. The first slot duration is provided with a power control signal and the second slot duration is provided with no signal at a partial duration thereof.
