摘要： The present invention relates to a method and to an apparatus for allocating a bandwidth in a wideband wireless communication system. Said method comprises: allocating a bandwidth to an uplink burst area in accordance with the bandwidth request received from at least one terminal; determining whether a preemptive grant bandwidth allocation is enabled or not; determining a preemptive grant terminal if the preemptive grant bandwidth allocation is enabled; and allocating a preemptive grant bandwidth within a residual bandwidth to the determined preemptive grant terminal. By doing this, the present invention can efficiently use the bandwidth of an uplink frame, and shorten the time taken for bandwidth request/approval between a terminal and a base station.

摘要： A large-scale fault tolerant asynchronous transfer mode (ATM) switch and a self-routing method in a 2n×n multiplexing switch. The 2n×n multiplexing switch includes 2n valid (VD) extracting parts generating valid (VD) signals, wherein it is used to select a cell among the 2n cells inputted every cell period according to the routing tag and store it to a FIFO; a FIFO selecting part selecting the FIFO where each cell selected using valid (VD) signals is to be stored and transmitting the cell to the corresponding FIFO; 2n shared FIFO buffers storing the 2n cells transmitted through the FIFO selecting part; outputting part transmitting the cells stored in the shared FIFO buffers to the output ports; cell counting part counting the number of cells stored in the shared FIFO buffers by using the information transmitted from the FIFO selecting part and outputting part; back-pressure signal generating part making the back-pressure signals by using the information from the cell counting part; and fault detector monitoring the faults of input ports by inputting the 2n valid (VD) signals from the valid (VD) extracting part.
