Abstract
A method and apparatus are described including determining a target congestion index, determining a congestion index based on information from a last back-off round, comparing the target congestion index with the congestion index, performing one of increasing a triggering set size by a first factor and decreasing the triggering set size by a second factor responsive to the comparison, determining if a communications medium is idle, adjusting a back-off counter responsive to the third determining act, determining if the back-off counter is equal to a triggering point in the triggering set and transmitting data responsive to the fourth determining act.
