Claim:
1. A network node arranged to: during a transmission time interval, determining a number of schedulable terminals having data to transmit; based on the number of schedulable terminals having data to transmit during the transmission time interval, deriving a first threshold value, the first threshold value comprising a number of consecutive blocking scheduling attempts giving rise to a congestion event; monitor the number of consecutive blocked scheduling attempts made by a terminal of the schedulable terminals; identify a congestion event for the terminal when the number of consecutive blocked scheduling attempts exceeds the first threshold value; monitor a number of consecutive blocked scheduling attempts made by each terminal of the schedulable terminals; and identify a congestion event for the network node when a number of terminals serviced by the network node having simultaneously identified congestion events exceeds a second threshold value.
