Abstract

La présente invention concerne un procédé et un dispositif de traitement de signal. Le procédé comprend les opérations suivantes : lorsqu'un premier terminal détecte qu'un chevauchement temporel existe entre la période de comptage d'un temporisateur et un créneau temporel, le comptage de temporisateur est arrêté, et lors de la détection du fait que le créneau temporel est terminé, le temporisateur peut être redémarré pour poursuivre le comptage, ce qui évite l'expiration du temporisateur provoquée par le comptage de temporisateur dans le créneau temporel, rendant le retard d'émission de signal plus long ; ou lorsque le premier terminal détecte qu'un chevauchement temporel existe entre la période de comptage du temporisateur et le créneau temporel, le temporisateur est redémarré pour commencer le comptage, de façon à réduire le retard d'émission de signal provoqué par le créneau temporel. Autrement dit, les modes de réalisation de la présente invention peuvent aider à réduire le retard d'émission du signal, et améliorer davantage la fiabilité de transmission de données.
