Abstract
(EN)
Disclosed are a method for sending information, a method for receiving information, an apparatus and a system, herein the method for sending information includes the following steps: a sending end using Downlink Control Information (DCI)/Uplink Control Information (UCI) to describe information about time that an unlicensed carrier is occupied; and the sending end sending the DCI/UCI information through an licensed carrier or the unlicensed carrier. Through the present invention, the problem of how to enable base stations to mutually inform about an occupation situation of the unlicensed carrier in the related art is solved, the coordination and utilization of the unlicensed carriers in a wireless communication system are facilitated the utilization rate of the unlicensed carriers is improved.

L'invention concerne un procédé d'émission d'informations, un procédé de réception d'informations, un appareil et un système. Le procédé d'émission d'informations comporte les étapes suivantes: une extrémité émettrice décrit des informations temporelles d'occupation d'une porteuse non soumise à une licence en utilisant des informations de commande de liaison descendante (DCI)/des informations de commande de liaison montante (UCI) (S102); et l'extrémité émettrice émet les informations DCI/UCI via une porteuse soumise à une licence ou la porteuse non soumise à une licence (S104). Au moyen de la présente invention, le problème de la façon d'informer entre elles des stations de base de l'état d'occupation de porteuses non soumises à des licences dans la technique apparentée est résolu, facilitant ainsi la coordination et l'utilisation de porteuses non soumises à des licences dans un système de communications sans fil et améliorant le taux d'utilisation des porteuses non soumises à des licences.
