Abstract

La présente demande concerne un procédé de transmission d'informations et un appareil de communication. Le procédé de transmission d'informations comprend les étapes suivantes : un dispositif terminal acquiert une première TA et une seconde TA ; et en outre, le dispositif terminal envoie ou reçoit des premières informations dans une première unité de temps, ou le dispositif terminal envoie ou reçoit les premières informations dans la première unité de temps, et envoie ou reçoit des secondes informations dans une seconde unité de temps, la position de domaine temporel de la première unité de temps étant associée à la première TA, et la position de domaine temporel de la seconde unité de temps étant associée à la seconde TA ; et la position de domaine temporel de la première unité de temps et la position de domaine temporel de la seconde unité de temps se chevauchent. Au moyen du procédé de transmission d'informations, lorsqu'une TA amène des unités de temps à se chevaucher mutuellement, un dispositif terminal peut encore transmettre des informations, ce qui permet d'assurer la stabilité de communication.
