Abstract

L'invention concerne un motif de symboles pilotes comprenant un ensemble d'emplacements τ de symboles pilotes situés dans une trame de référence temps/fréquence. Selon l'invention, les symboles pilotes sont transmis dans lesdits emplacements de symboles pilotes lors d'une radiotransmission (41). Un motif actuel de symboles pilotes est utilisé pour une radiotransmission s'effectuant dans un réseau de radiocommunication, d'une entité de réseau (31) à un terminal (32). Puis, une demande de modification (43) du motif de symboles pilotes est envoyée du terminal à l'entité de réseau; et un motif de symboles pilotes suivant est utilisé dans ladite radiotransmission.
