Title
(EN) METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR TRANSMETTRE DES INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
A method of transmitting channel information by a User Equipment (UE) when an uplink sub-frame is used for downlink transmission in a communication system using a dynamic Time Division Duplex (TDD) UpLink-DownLink (UL-DL) configuration is provided. The method includes receiving reconfiguration information for reconfiguration of TDD uplink and downlink from an evolved Node B (eNB), measuring interference in a first sub-frame changed from an uplink sub-frame to a downlink sub-frame by the reconfiguration, and transmitting information on interference measured in only the first sub-frame to the eNB in an uplink sub-frame according to a predetermined timing.
(FR)
L'invention concerne un procédé de transmission d'informations de canal par un équipement utilisateur (UE) lorsqu'une sous-trame de liaison montante est utilisée pour la transmission en liaison descendante dans un système de communication utilisant une configuration de liaison montante-liaison descendante (UL-DL) à duplexage dynamique par répartition dans le temps (TDD). Le procédé comprend la réception d'informations de reconfiguration pour la reconfiguration de liaison montante et liaison descendante TDD en provenance d'un nœud B évolué (eNB), la mesure d'interférence dans une première sous-trame changée d'une sous-trame de liaison montante en une sous-trame de liaison descendante par la reconfiguration et la transmission d'informations concernant l'interférence mesurée uniquement dans la première sous-trame à l'eNB dans une sous-trame de liaison montante selon une temporisation prédéfinie.
