DEVICE AND METHOD FOR SIGNAL OUTPUT, AND COMPUTER- READABLE RECORDING MEDIUM WITH RECORDED PROGRAM MAKING COMPUTER IMPLEMENT THE SAME SIGNAL OUTPUT METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the delay in data and to effectively use the band by opening a ranging window. SOLUTION: A transmission acknowledgement signal counting means 8 counts transmission acknowledgement signals which are not sent to a subscriber-side device 2 by opening the ranging window and a band control means 6 allocates a band to the unsent transmission acknowledgement signals so that they are preferentially transmitted at a next transmission change (in a next band change cycle).
