Abstract
(EN)
There is provided a method comprising providing, in dependence on a first subcarrier spacing of a first subframe structure, a second subcarrier spacing of a second subframe structure, wherein the first subframe structure has a first subframe length and at least one first cyclic prefix length and providing a second subframe length of the second subframe structure, the second subframe length comprising m symbols, wherein each symbol contains a second cyclic prefix, the second cyclic prefix length modified by a length variant.
(FR)
L'invention concerne un procédé consistant à fournir, en fonction d'un premier espacement de sous-porteuse d'une première structure de sous-trame, un second espacement de sous-porteuse d'une seconde structure de sous-trame, la première structure de sous-trame ayant une première longueur de sous-trame et au moins une première longueur de préfixe cyclique, et à fournir une seconde longueur de sous-trame de la seconde structure de sous-trame, la seconde longueur de sous-trame comprenant m symboles, chaque symbole contenant un second préfixe cyclique, la longueur du second préfixe cyclique étant modifiée par une variante de longueur.
