La présente invention concerne un procédé pour communiquer des signaux de radiomessagerie dans un système de communication qui comprend le couplage d'un équipement utilisateur à un réseau de communication par l'intermédiaire d'un canal de communication, et la sélection d'une occasion de radiomessagerie à partir de multiples occasions de radiomessagerie envoyées par le réseau de communication, les multiples occasions de radiomessagerie étant envoyées à l'aide d'un motif de répétition de radiomessagerie configuré pour permettre à l'équipement utilisateur couplé au réseau de communication de recevoir l'occasion de radiomessagerie sélectionnée sans conflit avec une occasion de radiomessagerie d'un second réseau de communication.
