Abstract

La présente divulgation concerne un procédé exécuté par un équipement utilisateur (UE). Le procédé consiste à : recevoir un message d'interrogation de capacité d'UE en provenance d'une station de base, et transmettre un message d'informations de capacité d'UE à la station de base, le message d'informations de capacité d'UE comprenant l'une d'une première capacité de réception de PSCCH et d'une seconde capacité de réception de PSCCH ; la première capacité de réception de PSCCH indique que le nombre de PSCCH qui peuvent être reçus dans un intervalle de temps est l'un de (1) et (2) ; (3) représente une configuration de largeur de bande de transmission maximale correspondant à une largeur de bande de canal d'UE correspondante dans une opération de porteuse unique de liaison latérale ; la seconde capacité de réception de PSCCH indique que le nombre de PSCCH qui peuvent être reçus dans un intervalle de temps est l'un parmi (4), (5), (6) et (7) ; et (8) représente une configuration de largeur de bande de transmission maximale correspondant à une largeur de bande de canal d'UE prédéfinie.
