    Abstract: Provided is a method for selecting an antenna performed by a receiver in a multi-antenna system. The method for selecting the antenna performed by the receiver in the multi-antenna system, comprises: a subcarrier group setting step for setting subcarrier groups by grouping subcarriers; a channel information acquisition step for acquiring channel information between a receiving end antenna and each of a plurality of transmission end antennas; an antenna selecting step for determining said subcarrier groups, which are to be transmitted to each of the plurality of said transmission end antennas on the basis of said channel information; and an antenna selection information transmission step for transmitting antenna selection information, which contains the result of said antenna selection, to a transmission end.

    Abstract: Provided is an apparatus for controlling subcarrier spacing in a system supporting multiple frequency bands. The apparatus for controlling a subcarrier spacing comprises: an interference detection unit detecting interference over multiple frequency bands; a system parameter provision unit providing system parameters related to a subcarrier spacing between the multiple frequency bands - for example RF, FFT size, and channel bandwidth; a subcarrier spacing control unit controlling the subcarrier spacing such that the detected interference is reduced, on the basis of the system parameters. In a system operating with multiple bands, different subcarrier spacing can be applied by each band, thereby controlling interference occurring in each band.

    Abstract: A method and an apparatus for allocating a hybrid burst in an OFDMA(Orthogonal Frequency Division Multiple Access) system is provided to reduce a burst allocation information bit and an overhead size by allocating a burst using a burst length. A method for allocating a hybrid burst in an OFDMA system includes the steps of: sequentially allocating the bursts, which are mapped along a frequency axis for a downlink data transmission, to each terminal(S630); dividing the data burst region of the sub-frame into at least one segment in the time region and sequentially allocating the bursts, which are mapped in the segment along the time axis, to each terminal(S650); sequentially allocating the bursts, which are mapped along a time axis for an uplink data transmission, to each terminal(S670); and sequentially allocating the bursts which are mapped along a whole time axis of a data burst region of the sub-frame to each terminal, to each terminal(S680).
