Title (EN) METHOD FOR TRANSMITTING REFERENCE SIGNAL
(FR) PROCÉDÉ DE TRANSMISSION DE SIGNAL DE RÉFÉRENCE
Abstract:
(EN) According to the present disclosure, behaviors of a Base Station (BS) and a User Equipment (UE) pertinent to Reference Signal (RS) transmissions are discussed. BS may configure RS corresponding to a set of antenna ports in two or more groups of Orthogonal Frequency Division Multiplexing (OFDM) symbols on a short Physical Downlink Sharing CHannel (sPDSCH), where subcarrier indices used for RS transmission are different between at least two groups of OFDM symbols. Then, BS may transmit the RS to UE. UE will receive RS and perform channel estimation based on the received RS.
(FR) La présente invention se rapporte à des comportements d'une station de base (BS) et d'un équipement d'utilisateur (UE) associés à des transmissions de signal de référence (RS). La BS peut configurer le RS correspondant à un ensemble de ports d'antenne en deux groupes, ou plus, de symboles de multiplexage par répartition orthogonale de la fréquence (OFDM) sur un canal de partage de liaison descendante physique court (sPDSCH), des indices de sous-porteuse servant à une transmission de RS étant différents entre au moins deux groupes de symboles OFDM. Ensuite, la BS peut transmettre le RS à l'UE. L'UE va recevoir le RS et va effectuer une estimation de canal sur la base du RS reçu.
