Abstract

Divers aspects de la présente divulgation concernent la détermination de ressources pour une transmission. Selon un aspect, un premier dispositif détermine un ensemble de ressources sur la base d'un ensemble de fréquences et d'une première fréquence parmi l'ensemble de fréquences. Le premier dispositif effectue ensuite une transmission vers un second dispositif sur une ressource parmi l'ensemble de ressources.
