Abstract: The present invention relates to an apparatus and a method for scheduling multiple bursts containing a collaborative spatial multiplexing (CSM) burst and a non-CSM burst in a broadband radio communication system. The method comprises the steps of packet-scheduling an uplink data packet corresponding to the bandwidth request from a terminal such that the packet is allocated to either the CSM burst or the non-CSM burst, determining a modulation and coding scheme (MCS) level and a transmission power level corresponding to the packet-scheduled uplink data packet using the maximum number of bytes for each MCS level in accordance with the types of the multiple bursts calculated for the terminal, determining a transmission power offset in accordance with the type of the burst to which the packet-scheduled uplink data packet is allocated using the MCS level and the power transmission level determined in the previous step, and generating MAP information for the terminal, containing burst allocation information of the uplink data packet and information of the transmission power offset determined in the previous step.

Abstract: Disclosed is an apparatus for switching MIMO modes, which can efficiently switch an MIMO mode of a mobile station. The apparatus for switching MIMO modes includes an MIMO mode determining unit, a staying time determining unit, and an MIMO mode switching unit. The MIMO mode determining unit determines a current MIMO mode of a mobile station. The staying time determining unit determines a first staying time in a first MIMO mode of the mobile station when the MIMO mode determining unit determines the current MIMO mode of the mobile station as the first MIMO mode for transmitting the same data through a plurality of antennas, and determines a second staying time in a second MIMO mode of the mobile station when the MIMO mode determining unit determines the current MIMO mode of the mobile station as the second MIMO mode for transmitting different data by antenna. The MIMO mode switching unit switches the MIMO mode of the mobile station to the second MIMO mode when the first staying time is greater than or equal to a first threshold staying time.

Abstract: An apparatus and method is provided for controlling power allocated to a burst of a downlink frame that a Base Station (BS) will transmit to a Mobile Station (MS) in a wireless communication system. The power control method includes comparing a measured Carrier to Interference and Noise Ratio (CINR) of the burst with a reference CINR of the burst, calculating a difference therebetween as a boosting power if the measured CINR is lower than the reference CINR, and calculating the difference as a deboosting power if the measured CINR is higher than the reference CINR; and setting a boosting power level so that a total boosting power including the boosting power or the deboosting power is set within a power range where a possible boosting range and a possible dynamic range cross each other.
