Abstract

A communication unit for communicating data in dependence on a priority associated with a data communication to be made by that communication unit and on a priority associated with a data communication to be made by another communication unit, the communication unit being arranged to assign a priority to a data communication to be made by the communication unit, make an adjustment to the priority to form an adjusted priority, the adjustment being independent of an adjustment made by the other communication unit to a priority assigned to a data communication to be made by that communication unit and communicate the adjusted priority to the other communication unit as being the priority associated with the data communication to be made by the communication unit.
