Abstract
(EN)
The present invention relates to a method and an apparatus for reporting channel state information (CSI) by a terminal in a wireless communication system. According to the present invention, a terminal may receive, from a base station, configuration information related to reporting of CSI, and the configuration information may include a threshold related to a particular condition for reception of the CSI which comprises a first part and a second part. The present invention may provide a method and an apparatus in which a terminal receives, from a base station, a first reference signal for channel measurement, measures a channel on the basis of the first reference signal, and reports CSI of the measured channel to a base station, wherein a part or entirety of the second part of the CSI is omitted on the basis of the particular condition.

La présente invention concerne un procédé et un appareil pour rapporter des informations d'état de canal (CSI) par un terminal dans un système de communication sans fil. Selon la présente invention, un terminal peut recevoir, en provenance d'une station de base, des informations de configuration relatives au rapport des CSI, et les informations de configuration peuvent comprendre un seuil relatif à une condition particulière pour la réception des CSI qui comprend une première partie et une seconde partie La présente invention peut fournir un procédé et un appareil dans lesquels un terminal reçoit, en provenance d'une station de base, un premier signal de référence pour une mesure de canal, mesure un canal sur la base du premier signal de référence, et rapporte les CSI du canal mesuré à une station de base, une partie ou la totalité de la seconde partie des CSI étant omise sur la base de la condition particulière.
