METHOD AND APPARATUS OF HYBRID BURST MAPPING IN OFDMA SYSTEMS |
摘要 |
<p>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).</p> |
