Abstract
In a contention-based network, a station, whose transmission is colliding with the transmission of another station and which heretofore would have transmitted a data packet immediately following its colliding transmission—as, for example, in a blackburst contention—suspends transmission immediately upon termination of the collision and, if necessary, at a particular point(s) in time during the collision. The station recommences transmission after a predetermined non-zero duration of time, or “time notch”, during which the medium is idle. In particular, a station that has won a blackburst contention separates its blackburst signal from its subsequent data transmission by a certain amount of time during which the medium is idle. Moreover, a station participating in a blackburst contention may cause the occurrence of a time notch at particular points in time during the contention in order that its access priority vis-a-vis other stations be determined.
