Abstract: front page image
(EN)A method and device for interference coordination in a communication system and the corresponding communication system, mobile station and base station (BS) are disclosed. In the method for interference coordination, a BS of a Pico Cell shifts a transmission frame backwards; a BS of a Macro Cell selects a subframe for transmitting a Channel State Information Reference Signal (CSI-RS) from transmission frames of the Macro Cell itself, to enable the subframe of the BS of the Macro Cell for transmitting CSI-RS to at least not overlap a subframe of the BS of the Macro Cell for transimitting a public channel and a subframe of the BS of the Pico cell partially; and the subframe of the BS of the Macro Cell for transmitting the public channel at least does not overlap the subframe of the BS of the Pico Cell for transmitting the public channel partially.
(FR)L'invention porte sur un procédé et un dispositif de coordination de brouillage dans un système de communication et sur le système de communication, la station mobile et la station de base (BS) correspondants. Dans le procédé de coordination de brouillage, une BS d'une picocellule décale une trame de transmission vers l'arrière; une BS d'une macrocellule sélectionne une sous-trame servant à transmettre un signal de référence d'informations d'état de canal (CSI-RS) parmi des trames de transmission de la macrocellule elle-même, afin de permettre que la sous-trame de la BS de la macrocellule servant à transmettre un CSI-RS au moins ne chevauche pas une sous-trame de la BS de la macrocellule servant à transmettre un canal public et une sous-trame de la BS de la picocellule partiellement; et la sous-trame de la BS de la macrocellule servant à transmettre le canal public au moins ne chevauche pas la sous-trame de la BS de la picocellule servant à transmettre le canal public partiellement.
