Abstract
(EN)
The present disclosure provides a method for receiving, by a terminal, a channel state information-reference signal (CSI-RS) in an unlicensed band. Particularly, the disclosure comprises: receiving CSI-RS resource information for receiving the CSI-RS and information relating to a first bandwidth allocated for the CSI-RS; and receiving the CSI-RS through CSI-RS resources included in at least one second bandwidth among multiple second bandwidths included in the first bandwidth, wherein the at least second bandwidth is determined on the basis of clear channel assessment (CCA) for each of the multiple second bandwidths.
(FR)
La présente invention concerne un procédé de réception, par un terminal, un signal de référence d'informations d'état de canal (CSI-RS) dans une bande sans licence. En particulier, l'invention comporte les étapes consistant à: recevoir des informations de ressources de CSI-RS pour recevoir les CSI-RS et des informations se rapportant à une première bande passante allouée pour le CSI-RS; et recevoir le CSI-RS par l'intermédiaire de ressources de CSI-RS comprises dans au moins une seconde bande passante parmi de multiples secondes bandes passantes incluses dans la première bande passante, la ou les secondes bandes passantes étant déterminées sur la base d'une évaluation de canal dégagé (CCA) pour chacune des multiples secondes bandes passantes.
