Abstract
(EN)
Provided are a base station, a terminal, and a communication method that enable throughput to be improved when using many antennas. This base station is provided with a transmission unit for transmitting a channel state information reference signal (CSI-RS) and setting information for the CSI-RS to a terminal, and a receiving unit for receiving the channel state information (CSI) pertaining to the CSI-RS from the terminal, wherein the CSI-RS is periodic CSI-RS that is periodically transmitted or aperiodic CSI-RS that is aperiodically transmitted, and the CSI-RS setting information includes information representing feedback information format for reporting the CSI.
(FR)
L'invention concerne une station de base, un terminal et un procédé de communication permettant une amélioration du débit grâce à l'utilisation d'un grand nombre d'antennes. La station de base est équipée d'une unité d'émission destinée à transmettre un signal de référence d'information d'état de canal (CSI-RS) et une information de réglage pour le signal CSI-RS à un terminal, et une unité de réception destinée à recevoir l'information d'état de canal (CSI) se rapportant au CSI-RS en provenance du terminal, le CSI-RS est un CSI-RS périodique émis périodiquement ou un CSI-RS apériodique émis de manière apériodique; et l'information de réglage du CSI-RS comprend une information représentant le format d'information de retour pour la notification du CSI.
