Title
(EN) LINK FAILURE RECOVERY PROCEDURE FOR A PRIMARY CELL (PCELL) AND A SECONDARY CELL (SCELL)
(FR) PROCÉDÉ DE RÉCUPÉRATION APRÈS DÉFAILLANCE DE LIAISON POUR UNE CELLULE PRIMAIRE (PCELL) ET UNE CELLULE SECONDAIRE (SCELL)
Abstract
(EN)
Wireless communications systems and methods related to handling link failures in a first cell and a second cell are provided. A wireless communication device can detect a first link failure associated with a first cell and can detect a second link failure associated with a second cell. Additionally, the wireless communication device can perform a link failure recovery procedure. This may include prioritizing a first link failure recovery for the first cell over a second link failure recovery for the second cell. Other aspects and features are also claimed and described.
(FR)
L'invention concerne des systèmes de communication sans fil et des procédés liés à la gestion des défaillances de liaison dans une première cellule et une seconde cellule. Un dispositif de communication sans fil peut détecter une première défaillance de liaison associée à une première cellule et peut détecter une seconde défaillance de liaison associée à une seconde cellule. De plus, le dispositif de communication sans fil peut effectuer un procédé de récupération après défaillance de liaison. Ceci peut consister à accorder la priorité à une première récupération après défaillance de liaison pour la première cellule sur une seconde récupération après défaillance de liaison pour la seconde cellule. D'autres aspects et caractéristiques sont également revendiqués et décrits.
