A method for configurating a basic signal allocation unit and a method of transmitting signals using the configurated basic signal allocation unit are disclosed. In particular, a basic frequency domain signal allocation unit is configurated by considering at least one selected from the group consisting of a signaling overhead, a size of a coherent bandwidth and a number of divisors among specific numbers and an OFDM symbol number corresponding to a multiple of a subframe unit, each of the specific numbers multiplied to a predetermined subcarrier spacing to enable a result value of the multiplication to have a difference smaller than a prescribed threshold from a divisor of a system bandwidth. And, a time domain unit is configurated by 1-subframe unit. Accordingly, signaling overhead can be efficiently reduced.

L'invention concerne un procédé pour configurer une unité d'attribution de signal de base et un procédé de transmission de signaux utilisant celle-ci. En particulier, une unité d'attribution de signal de domaine fréquentiel de base est configurée, compte tenu d'au moins un élément sélectionné dans le groupe comprenant le surdébit de signalisation, la taille d'une bande passante cohérente et des diviseurs spécifiques et un nombre de symboles OFDM correspondant à un multiple d'une unité de sous-trames, chacun des nombres spécifiques étant multiplié par un espacement de sous-porteuses prédéterminé afin que le résultat de la multiplication présente une différence inférieure à un seuil prescrit à partir d'un diviseur de la bande passante du système. Et une unité de domaine temporel est configurée par une unité de sous-trame 1. L'invention permet de réduire efficacement le surdébit de signalisation.
