Title (EN) INCREASING CSI-RS OVERHEAD VIA ANTENNA PORT AUGMENTATION
(FR) AMÉLIORER LE SURDÉBIT CSI-RS PAR UNE AUGMENTATION DU NOMBRE DE BORNES D'ANTENNES
Abstract: front page image
(EN)A method of wireless communication is presented. The method includes signaling a first number of channel state information-reference signal (CSI-RS) ports corresponding to resource elements (REs) and a second number of virtual antenna ports, the second number being less than or equal to the first number. The method also includes transmitting CSI-RS on each virtual antenna port, the CSI-RS mapped to at least a portion of the REs.
(FR)L'invention concerne un procédé de communication sans fil. Ce procédé comprend l'étape qui consiste à signaler un premier nombre de bornes de signal de référence d'informations d'état de canal (CSI-RS) correspondant à des éléments de ressource (RE) et un deuxième nombre de bornes d'antennes virtuelles, le deuxième nombre étant inférieur au premier nombre. Cette invention comprend également l'étape qui consiste à envoyer le CSI-RS sur chaque borne d'antenne virtuelle, une mise en correspondance étant établie entre ledit CSI-RS et au moins une partie des éléments RE.
