Title
(EN) BEAMFORMING SWEEPING AND TRAINING IN A FLEXIBLE FRAME STRUCTURE FOR NEW RADIO
(FR) BALAYAGE ET APPRENTISSAGE DE FORMATION DE FAISCEAUX DANS UNE STRUCTURE DE TRAME FLEXIBLE POUR UNE NOUVELLE RADIO
Abstract
(EN)
The present application is at least directed to an apparatus on a network including a non-transitory memory including instructions stored thereon for beamforming training during an interval in the network. The apparatus also includes a processor, operably coupled to the non-transitory memory, capable of executing the instructions of receiving, from a new radio node, a beamforming training signal and beam identification for each of plural beams during the interval. The processor is also configured to execute the instructions of determining an optimal transmission beam of the new radio node based on the beamforming training signals of the plural beams. The processor is further configured to execute the instructions of transmitting, to the new radio node, a signal including a beam identification of the optimal transmission beam and an identification of the apparatus during the interval. The processor is further configured to execute the instructions of receiving, from the new radio node, an optimal transmission beam for the apparatus including a beam identification based upon a determination from the new radio during the interval.

L’invention concerne au moins un appareil sur un réseau comprenant une mémoire non transitoire dans laquelle sont stockées des instructions en vue d’un apprentissage de formation de faisceaux pendant un intervalle dans le réseau. L'appareil comprend également un processeur, couplé de manière fonctionnelle à la mémoire non transitoire, qui permet d’exécuter les instructions visant à recevoir, d'un nouveau nœud radio, un signal d'apprentissage de formation de faisceaux ainsi qu’une identification de faisceaux pour chaque faisceau de la pluralité de faisceaux pendant l'intervalle. L’invention concerne au moins un appareil sur un réseau comprenant une mémoire non transitoire dans laquelle sont stockées des instructions en vue d’un apprentissage de formation de faisceaux pendant un intervalle dans le réseau. Le processeur est également configuré pour exécuter les instructions visant à transmettre, au nouveau nœud radio, un signal comprenant une identification de faisceau du faisceau de transmission optimal et une identification de l'appareil pendant l'intervalle. Le processeur est également configuré pour exécuter les instructions visant à déterminer un faisceau de transmission optimal du nouveau nœud radio d’après les signaux d'apprentissage de formation de faisceaux de la pluralité de faisceaux.
