Abstract
(EN)
An apparatus of a user equipment (UE) may include memory and processing circuitry coupled to the memory. The processing circuitry may be configured to estimate a communication channel for a multi-carrier signal based on a received reference signal, the multi-carrier signal aggregating a plurality of component carriers. During a transmission time interval of the multi-carrier signal, the UE can perform a global search over a beam search space to obtain a beam index recommendation for a component carrier of the plurality of component carriers. The beam index recommendation corresponds to a maximized channel quality metric of the estimated communication channel and is indicative of a beam grid within the beam search space. The UE can perform a localized search of a subset of the beam search space to obtain a second beam index recommendation for a second component carrier of the plurality of component carriers.

La présente invention concerne un appareil d'un équipement utilisateur (UE) qui peut comprendre une mémoire et un ensemble de circuits de traitement couplé à la mémoire. L'ensemble de circuits de traitement peut être configuré afin d'estimer un canal de communication pour un signal multiporteuse basé sur un signal de référence reçu, le signal multiporteuse regroupant une pluralité de porteuses composantes. Pendant un intervalle de temps de transmission du signal multiporteuse, l'UE peut réaliser une recherche globale sur un espace de recherche de faisceau afin d'obtenir une recommandation d'indice de faisceau pour une porteuse composante de la pluralité de porteuses composantes. La recommandation d'indice de faisceau correspond à une mesure de qualité de canal maximisée du canal de communication estimé et indique une grille de faisceaux à l'intérieur de l'espace de recherche de faisceau. L'UE peut réaliser une recherche localisée d'un sous-ensemble de l'espace de recherche de faisceau afin d'obtenir une seconde recommandation d'indice de faisceau pour une seconde porteuse composante de la pluralité de porteuses composantes.
