Abstract
(EN)
One embodiment of the present invention relates to a method by which a first base station measures a channel with a second base station in a wireless communication system, the channel measuring method comprising the steps of: receiving a reference signal transmitted by the second base station, in a first subframe; and estimating a channel with the second base station on the basis of the reference signal, wherein the first subframe is obtained by changing a subframe indicated for an uplink by system information into a subframe for a downlink by the second base station.

Selon un mode de réalisation, la présente invention se rapporte à un procédé permettant à une première station de base de mesurer un canal qui la relie à une seconde station de base dans un système de communication sans fil. Le procédé de mesure de canal comprend les étapes suivantes : la réception d'un signal de référence transmis par la seconde station de base dans un premier secteur de trame ; et l'estimation d'un canal qui relie la première station de base à la seconde station de base grâce au signal de référence, le premier secteur de trame étant obtenu par la modification, réalisée par la seconde station de base, d'un secteur de trame que les informations système indiquent comme étant destiné à la liaison montante, afin d'en faire un secteur de trame destiné à la liaison descendante.
