Abstract

Selon divers aspects, la présente divulgation porte sur le domaine de la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut établir, à l'aide d'un premier module d'identification d'abonné (SIM), une première connexion de communication, le premier SIM étant configuré pour fonctionner dans un mode de réception de simultanéité complète, et une première et une deuxième antenne étant associées à une première chaîne de réception correspondant au premier SIM. L'UE peut établir, à l'aide d'un second SIM, une seconde connexion de communication, une troisième et une quatrième antenne étant associées à une seconde chaîne de réception correspondant au second SIM. L'UE peut recevoir, à l'aide des première et deuxième antennes, dans un mode à double SIM double actif (DSDA) à co-bande, des premières données reçues. L'UE peut recevoir, à l'aide des troisième et quatrième antennes, des secondes données reçues et peut réacheminer les secondes données reçues au premier SIM. De nombreux autres aspects sont décrits.
