Abstract

En fremgangsmåte for å overføre en datapakke i et trådløst kommunikasjonssystem begynner med å lage et ankomsttids- (TOA) vindu med en vindusstart (WS) og en vindusslutt (WE). TOA av datapakken ved luftgrensesnittet for overføringen bestemmes, og ytterligere tiltak tas avhengig av når datapakken ankommer i forhold til TOA vinduet. Datapakken blir bufret hvis TOA er før WS. Datapakken blir overført hvis TOA er innenfor TOA vinduet. Datapakken blir forkastet hvis TOA etter WE.
