Title
(EN) SECONDARY CELL RECOVERY FOR SECONDARY CELL GROUPS
(FR) RÉCUPÉRATION DE CELLULES SECONDAIRES POUR GROUPES DE CELLULES SECONDAIRES
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, information identifying a secondary cell group including a plurality of secondary cells. The user equipment may perform, after detecting a beam failure with a secondary cell of the secondary cell group, a beam failure recovery action associated with the secondary cell group. Numerous other aspects are provided.

Divers aspects de la présente invention concernent de manière générale les communications sans fil. Dans certains aspects, un équipement utilisateur (UE) peut recevoir, en provenance d'une station de base (BS), des informations identifiant un groupe de cellules secondaires comprenant une pluralité de cellules secondaires. L'équipement utilisateur peut effectuer, après détection d'une défaillance de faisceau avec une cellule secondaire du groupe de cellules secondaires, une action de reprise sur défaillance de faisceau associée au groupe de cellules secondaires. De nombreux autres aspects sont également décrits.
