Abstract

Se proporciona recuperación de falla de enlace de radio (RLF) sobre enlace lateral (SL). En este documento se describen sistemas y métodos que evitan la activación de un procedimiento de restablecimiento de control de recursos de radio (RRC) por parte de un equipo de usuario (UE) en una RLF, evitando así la sobrecarga de señalización innecesaria y la interrupción de la conectividad. En algunas modalidades, el UE (UE1) está en comunicación con otro UE (UE2) a través de un SL, y el UE1 detecta una RLF a través de un enlace de radio. Al detectar la RLF, el UE1 envía un mensaje de falla al UE2 a través de un canal de SL que identifica la RLF detectada. Al recibir el mensaje de falla del UE1, el UE2 reenvía el mensaje a la red a través de un enlace Uu disponible entre el UE2 y la red. En algunas modalidades, antes de enviar el mensaje de falla a la red, el UE2 lleva a cabo un procedimiento de acceso aleatorio a una célula seleccionada si no hay un enlace de radio Uu disponible y activo.
