Title
(EN) METHOD AND APPARATUS FOR OPERATING SUBFRAME AND TRANSMITTING CHANNEL INFORMAITON FOR CONTROLLING INTERFERENCE IN COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL D'EXPLOITATION DE SOUS-TRAME ET DE TRANSMISSION DES INFORMATIONS DE CANAL POUR LIMITER LE BROUILLAGE DANS SYSTÈME DE COMMUNICATION
Abstract
(EN) A method and an apparatus for operating a subframe and transmitting channel information for controlling interference in a communication system are provided. If a macro evolved Node B (eNodeB) determines and reports an uplink protection subframe for suppressing uplink transmission to a neighboring eNodeB, transmits scheduling information for uplink data through a downlink subframe corresponding to an uplink protection subframe, and the uplink protection subframe determined by the neighboring eNodeB is reported, a small eNodeB sets the reported uplink protection subframe as a flexible subframe, and uses the flexible subframe for downlink transmission. If the flexible subframe is used for the downlink transmission, a terminal of the small eNodeB measures and transmits non-period channel information in the flexible subframe through at least one uplink subframe.
(FR) L'invention porte sur un procédé et sur un appareil qui permettent d'exploiter une sous-trame et de transmettre des informations de canal pour limiter le brouillage dans un système de communication. Si un macro-nœud B évolué (eNodeB) détermine et rapporte une sous-trame de protection de liaison montante pour supprimer une transmission en liaison montante à un nœud B évolué voisin, transmet des informations de planification pour des données de liaison montante par une sous-trame de liaison descendante correspondant à une sous-trame de protection de liaison montante, et la sous-trame de protection de liaison montante déterminée par le nœud B évolué voisin est rapportée, alors un petit nœud B évolué règle la sous-trame de protection de liaison montante rapportée en tant que sous-trame flexible, et utilise la sous-trame flexible pour une transmission en liaison descendante. Si la sous-trame flexible est utilisée pour la transmission en liaison descendante, un terminal du petit nœud B évolué mesure et transmet des informations de canal non périodiques dans la sous-trame flexible par l'intermédiaire d'au moins une sous-trame de liaison montante.
