Abstract

Des modes de réalisation de la présente demande concernent un procédé de communication et un dispositif associé. Un équipement terminal envoie des premières informations d'indication à un dispositif de réseau, les premières informations d'indication étant utilisées pour indiquer que l'équipement terminal prend en charge le fait qu'une première porteuse de technologie d'évolution à long terme (LTE) est non contiguë à une première porteuse nouvelle radio (NR), et la première porteuse LTE et la première porteuse NR sont deux porteuses dans une EN-DC intrabande. L'équipement terminal reçoit des informations de configuration envoyées par le dispositif de réseau, et accède à un réseau sur la base d'une première règle et des informations de configuration, les informations de configuration étant utilisées pour configurer la première porteuse LTE et la première porteuse NR, et la première règle comprenant : un espacement de canal nominal qui est égal à un espacement de canal entre une porteuse LTE et une porteuse NR dans une EN-DC non contiguë intrabande, l'espacement de canal nominal représentant l'espacement de canal entre une porteuse LTE et une porteuse NR adjacentes l'une à l'autre dans une EN-DC contiguë intrabande. La première règle peut permettre à un équipement terminal qui signale la capacité de prendre uniquement en charge le fait qu'une porteuse LTE et une porteuse NR dans l'EN-DC intrabande sont non contiguës d'accéder à un réseau qui prend uniquement en charge le fait que la porteuse LTE et la porteuse NR dans l'EN-DC intrabande sont contiguës.
