Title
(EN) SHARED COMMON BEAM UPDATE ACROSS MULTIPLE COMPONENT CARRIERS
(FR) MISE À JOUR DE FAISCEAU COMMUN PARTAGÉ À TRAVERS DE MULTIPLES PORTEUSES COMPOSANTES
Abstract
(EN) A base station and a UE may communicate using directional beams, such as a downlink directional beam (used to transmit downlink channels) and an uplink directional beam (used to transmit uplink channels), each beam carrying one or more data channels, control channels, and/or reference signals. According to one aspect, signaling for managing the uplink channels and downlink channels may be sent over a shared common beam. The shared common beam is distinct from the uplink directional beam and the downlink directional beam. In one example, a first shared common channel may serve to manage or update uplink data channels (on the uplink directional beam) and downlink data channels (on the downlink directional beam), while a second shared common channel may serve to manage or update uplink control channels (on the uplink directional beam) and downlink control channels (on the downlink directional beam).
(FR) Une station de base et un équipement utilisateur (UE), lesquels peuvent communiquer à l'aide de faisceaux directionnels, tels qu'un faisceau directionnel de liaison descendante (utilisé pour transmettre des canaux de liaison descendante) et un faisceau directionnel de liaison montante (utilisé pour transmettre des canaux de liaison montante), chaque faisceau transportant un ou plusieurs canaux de données, canaux de commande et/ou signaux de référence. Selon un aspect, une signalisation de gestion des canaux de liaison montante et des canaux de liaison descendante peut être envoyée sur un faisceau commun partagé. Le faisceau commun partagé est distinct du faisceau directionnel de liaison montante et du faisceau directionnel de liaison descendante. Dans un exemple, un premier canal commun partagé peut servir à gérer ou à mettre à jour des canaux de données de liaison montante (sur le faisceau directionnel de liaison montante) et des canaux de données de liaison descendante (sur le faisceau directionnel de liaison descendante), tandis qu'un second canal commun partagé peut servir à gérer ou à mettre à jour des canaux de commande de liaison montante (sur le faisceau directionnel de liaison montante) et des canaux de commande de liaison descendante (sur le faisceau directionnel de liaison descendante).
