Abstract:
(EN) Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a connection configuration message to establish a flow for a call that is associated with a fallback from a 5G/NR base station to a 4G/LTE base station, wherein the connection configuration message does not include bearer information for a 5G/NR bearer; provide an indication that establishment of the flow is successful without establishment of the 5G/NR bearer; and/or perform the call using a 4G/LTE bearer via the 4G/LTE base station. Numerous other aspects are provided.
(FR) Certains aspects généraux de la présente invention concernent une communication sans fil. Selon certains aspects, un équipement d'utilisateur peut : recevoir un message de configuration de connexion pour l'établissement d’un flux pour un appel qui est associé à un repli d'une station de base 5G/NR à une station de base 4G/LTE, le message de configuration de connexion ne contenant pas d'informations de support pour un support 5G/NR ; fournir une indication de l'établissement réussi du flux sans établissement du support 5G/NR ; et/ou exécuter l'appel au moyen d’un support 4G/LTE via la station de base 4G/LTE. L'invention présente également de nombreux autres aspects.
