Abstract

La présente invention concerne un procédé de communication sans fil et un dispositif terminal. Lorsqu'un conflit de ressources se produit, des ressources disponibles sont utilisées au maximum pour une transmission, ce qui évite le gaspillage de ressources. Le procédé de communication sans fil comprend les étapes suivantes : lorsqu'il existe un conflit de ressources entre une première ressource et une seconde ressource, un dispositif terminal conditionne la première ressource et/ou le dispositif terminal utilise la première ressource pour la transmission.
