발명의 명칭: (EN) MULTI-BEAM CSI REPORTING
(FR) RAPPORT DE CSI MULTI-FAISCEAU
요약서:
(EN) Systems and methods for multi-beam Channel State Information (CSI) reporting are provided. In some embodiments, a method of operation of a second node connected to a first node in a wireless communication network for reporting multi-beam CSI includes reporting a rank indicator and a beam count indicator in a first transmission to the first node. The method also includes reporting a cophasing indicator in a second transmission to the first node. The cophasing indicator identifies a selected entry of a codebook of cophasing coefficients where the number of bits in the cophasing indicator is identified by at least one of the beam count indicator and the rank indicator. In this way, feedback for both a rank indicator and a beam count indicator may be possible which may allow robust feedback and variably sized cophasing and beam index indicators.
(FR) L'invention concerne des systèmes et des procédés de rapport d'informations d'état de canal (CSI) multi-faisceau. Dans certains modes de réalisation, un procédé de fonctionnement d'un second noeud connecté à un premier noeud dans un réseau de communication sans fil pour rapporter des CSI multi-faisceau consiste à rapporter un indicateur de rang et un indicateur de comptage de faisceau dans une première transmission au premier noeud. Le procédé consiste également à rapporter un indicateur de cophasage dans une seconde transmission au premier noeud. L'indicateur de cophasage identifie une entrée sélectionnée d'un livre de codes de coefficients de cophasage, le nombre de bits dans l'indicateur de cophasage étant identifié par l'indicateur de comptage de faisceau et/ou de l'indicateur de rang. De cette manière, une rétroaction pour un indicateur de rang et un indicateur de comptage de faisceau peut être possible, ce qui peut permettre une rétroaction robuste et des indicateurs de cophasage et d'indice de faisceau de taille variable.
