Title
(EN) FAST SECONDARY CELL RECOVERY FOR ULTRA-RELIABLE LOW-LATENCY COMMUNICATION
(FR) RÉCUPÉRATION RAPIDE DE CELLULE SECONDAIRE POUR COMMUNICATION À FAIBLE LATENCE ULTRA-FIABLE
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide, to a first cell, a beam failure indication associated with a beam of a secondary cell. The beam failure indication may be provided via a dedicated physical uplink control channel (PUCCH) resource. The user equipment may provide, based at least in part on providing the beam failure indication, a beam index report to a second cell. The beam index report may be provided to cause recovery of the secondary cell to be triggered. The beam index report may include information that identifies a preferred beam associated with the recovery of the secondary cell. Numerous other aspects are provided.

Divers aspects de la présente invention concernent de manière générale la communication sans fil. Selon certains aspects, un équipement d'utilisateur peut fournir, à une première cellule, une indication de défaillance de faisceau associée à un faisceau d'une cellule secondaire. L'indication de défaillance de faisceau peut être fournie par l'intermédiaire d'une ressource de canal physique de commande de liaison montante (PUCCH) dédiée. L'équipement d'utilisateur peut fournir, en se basant au moins en partie sur la fourniture de l'indication de défaillance de faisceau, un rapport d'indice de faisceau à une deuxième cellule. Le rapport d'indice de faisceau peut être fourni pour provoquer le déclenchement de la récupération de la cellule secondaire. Le rapport d'indice de faisceau peut comprendre des informations qui identifient un faisceau préféré associé à la récupération de la cellule secondaire. L'invention se présente également sous de nombreux autres aspects.
