Abstract
A method includes directly receiving, at a first station, a signal transmitted from a second station. Each of the first and second stations respectively includes a link status indicator that indicates whether a direct link exists between the first and second stations. The signal was transmitted based on the link status indicator of the second station indicating that a direct link does exist between the first and second stations. Responsive to the link status indicator of the first station indicating that a direct link does not exist between the first station and the second station, the signal is dropped, and a teardown signal is transmitted from the first station to the second station. Responsive to the teardown signal, the link status indicator of the second station is to be changed, by the second station, to indicate that a direct link does not exist between the first and second stations.
