Title
(EN) BEAM FAILURE DETECTION AND RECOVERY WITH CARRIER AGGREGATION
(FR) DÉTECTION ET REPRISE SUR DÉFAILLANCE DE FAISCEAU AVEC AGRÉGATION DE PORTEUSES
Abstract
(EN) This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a user equipment (UE) detects a beam failure of a first beam for a first component carrier (CC) based on a link quality associated with the first beam for the first CC. The first CC and a second CC are within a same group of CCs. The UE initiates one or more beam failure recovery operations associated with any CC within the same group of CCs as the first and second CCs based on a determination of a beam failure of a second beam for the second CC. The determination is based on the detection of the beam failure for the first CC and based on the first CC and the second CC being within the same group of CCs.
(FR) La présente divulgation concerne des systèmes, des procédés et des appareils, y compris des programmes informatiques codés sur des supports de informatiques, pour une communication sans fil. Selon un aspect de la divulgation, un équipement utilisateur (UE) détecte une défaillance de faisceau d'un premier faisceau pour une première porteuse composante (CC) sur la base d'une qualité de liaison associée au premier faisceau pour la première CC. La première CC et une seconde CC sont dans un même groupe de CC. L'UE déclenche une ou plusieurs opérations de reprise sur défaillance de faisceau associées à une quelconque CC dans le même groupe de CC en tant que première et seconde CC sur la base d'une détermination d'une défaillance de faisceau d'un second faisceau pour la seconde CC. La détermination est basée sur la détection de la défaillance de faisceau pour la première CC et sur le fait que la première CC et la seconde CC se trouvent dans le même groupe de CC.
