Abstract

Procédé de duplexage par division de fréquence (FDD) en half-duplex (HD) pour des systèmes de communication sans fil, mettant en oeuvre une priorisation des voies respectivement montante et descendante pour un terminal de communication mobile de type HD-FDD lors d'une transition entre une sous-trame de voie descendante (DL), numérotée n, et une sous trame de voie montante (UL), numérotée n + 1. Ce procédé comprend une étape d'envoi par une station de base d'un message d'allocation, une étape de réception du message d'allocation par ledit terminal et une étape de traitement dudit message d'allocation par ledit terminal.
