Title (EN) USER EQUIPMENT AND METHOD FOR SELECTION OF CSI REFERENCE SIGNAL AND CSI REPORTING IN A BEAM FORMING SYSTEM WITH MULTIPLE BEAMS
(FR) ÉQUIPEMENT UTILISATEUR ET PROCÉDÉ DE SÉLECTION DE SIGNAL DE RÉFÉRENCE DE CSI ET SIGNALEMENT DE CSI DANS UN SYSTÈME DE FORMATION DE FAISCEAU À FAISCEAUX MULTIPLES
Abstract:
(EN) A user equipment (UE) includes a receiver that receives multiple Reference Signals (RSs) transmitted using respectively different radio resources from a base station (BS), a processor that selects, out of RS Resource Indicators (RRIs) associated with the radio resources used for RS transmission, multiple RRIs, and a transmitter that transmits the multiple RRIs to the BS. The processor derives Channel State Information (CSI) in each of the RRIs using the RSs. The transmitter transmits the CSI corresponding to the multiple RRIs to the BS. The transmitter transmits the CSI corresponding to a part of the multiple RRIs. The transmitter transmits a RRI rank that indicates a number of the selected RRIs.
(FR) L'invention concerne un équipement d'utilisateur (UE) comprenant un récepteur qui reçoit de multiples signaux de référence (RS) émis en utilisant respectivement des ressources radioélectriques différentes depuis une station de base (BS), un processeur qui sélectionne plusieurs indicateurs de ressources RS (RRI) parmi des RRI associés aux ressources radioélectriques utilisées pour l'émission des RS, et un émetteur qui émet les multiples RRI à la BS. Le processeur dérive des informations d'état de canal (CSI) dans chacun des RRI en utilisant les RS. L'émetteur émet les CSI correspondant aux multiples RRI à la BS. L'émetteur émet les CSI correspondant à une partie des multiples RRI. L'émetteur émet un degré de RRI qui indique un nombre de RRI sélectionnés.
