Title (EN) BEAM INFORMATION FEEDBACK METHOD AND USER APPARATUS
(FR) PROCÉDÉ DE RÉTROACTION D'INFORMATIONS DE FAISCEAU ET APPAREIL D'UTILISATEUR
(ZH) 波束信息反馈方法及用户装置
Abstract:
(EN) Provided is a method for feeding back beam information executed by a user apparatus, comprising: according to a beam selection result, determining a first beam and multiple second beams; according to the beam power of the multiple second beams, sending a beam index of the multiple second beams to a base station; sending wideband beam information corresponding to the beam index of the multiple second beams; and sending sub-band beam information corresponding to the beam index of the multiple second beams.
(FR) L'invention concerne un procédé pour renvoyer des informations de faisceau exécuté par un appareil d'utilisateur, comprenant les étapes suivantes : selon un résultat de sélection de faisceau, déterminer un premier faisceau et de multiples deuxièmes faisceaux ; selon la puissance de faisceau des multiples deuxièmes faisceaux, envoyer un indice de faisceau des multiples deuxièmes faisceaux à une station de base ; envoyer des informations de faisceau à large bande correspondant à l'indice de faisceau des multiples deuxièmes faisceaux ; et envoyer des informations de faisceau de sous-bande correspondant à l'indice de faisceau des multiples deuxièmes faisceaux.
(ZH) 本发明提供了一种由用户装置执行的波束信息反馈方法,包括:根据波束选择结果,确定第一波束和多个第二波束;根据所述多个第二波束的波束功率,向基站发送所述多个第二波束的波束索引;与所述多个第二波束的波束索引对应地发送宽带波束信息;以及与所述多个第二波束的波束索引对应地发送子带波束信息。
