Selon les modes de réalisation de la présente demande, un procédé de configuration permettant une agrégation de porteuses à multiplexage par répartition dans le temps comprend les étapes suivantes : un terminal envoie des premières informations de capacité à un dispositif côté réseau, les premières informations de capacité indiquant que le terminal a la capacité suivante : prendre en charge une opération semi-duplex dans une agrégation de porteuses (CA) à multiplexage par répartition dans le temps (TDD) de cellules de desserte dont les espacements de sous-porteuses (SCS) ne sont pas totalement identiques ; et le terminal reçoit des informations de configuration envoyées par le dispositif côté réseau, les informations de configuration servant à configurer une CA TDD cible, et les SCS d'une pluralité de cellules de desserte configurées dans la CA TDD cible n'étant pas totalement identiques.
