Abstract

La présente invention concerne un procédé et un appareil de mappage de ressources. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des informations de configuration de ressource envoyées par un dispositif de réseau, les informations de configuration de ressource étant utilisées pour indiquer des informations de paramètre de N parties de bande passante de saut de fréquence au dispositif terminal, l'expression N ≥ 2 étant satisfaite, la longueur de bande passante de l'une quelconque des N parties de bande passante de saut de fréquence étant inférieure ou égale à la longueur de bande passante d'une partie de bande passante active (BP active) du dispositif terminal ; le dispositif terminal détermine, en fonction des informations de configuration de ressource et des informations de planification de liaison montante, une ressource de transmission physique de liaison montante attribuée par le dispositif de réseau. En permettant que la longueur de bande passante de l'une quelconque des N parties de bande passante de saut de fréquence soit inférieure ou égale à la longueur de bande passante de la BP active du dispositif terminal, le dispositif terminal, lors de l'exécution d'un saut de fréquence en fonction des informations de paramètre de l'une quelconque des N parties de bande passante de saut de fréquence, ne sauterait pas la BP active du dispositif terminal.
