Title (EN) METHOD FOR REDUCING INTERFERENCE BETWEEN UPLINK SIGNAL AND DOWNLINK SIGNAL, AND DEVICE THEREFOR
(FR) PROCÉDÉ DE RÉDUCTION D'INTERFÉRENCE ENTRE UN SIGNAL DE LIAISON MONTANTE ET UN SIGNAL DE LIAISON DESCENDANTE, ET DISPOSITIF ASSOCIÉ
(KO) 상향링크 신호와 하향링크 신호 간의 간섭을 감소시키는 방법 및 이를 위한 장치
Abstract: front page image
(EN)The present invention provides a method for a base station to transmit a downlink signal, in order to reduce interference between uplink transmission and downlink transmission in a wireless communication system. Particularly, the method is characterized by: a step of setting a power decrease region in which downlink transmission power is transmitted by being lower than that of another region; a step of separating and generating a first transmission block corresponding to the power decrease region, and a second transmission block not corresponding to the power decrease region; and a step of mapping downlink data to the first transmission block and the second transmission block, respectively, wherein the first transmission block is transmitted with the power allocated to the power decrease region, and the second transmission block is transmitted with the power allocated to the region other than the power decrease region.
(FR)La présente invention concerne un procédé destiné à une station de base en vue de transmettre un signal de liaison descendante, afin de réduire une interférence entre une transmission de liaison montante et une transmission de liaison descendante dans un système de communication sans fil. En particulier, le procédé comprend les étapes consistant : à définir une région de diminution de puissance dans laquelle une puissance de transmission de liaison descendante est transmise en étant inférieure à celle d'une autre région ; à séparer et à générer un premier bloc de transmission correspondant à une région de diminution de puissance, et un second bloc de transmission ne correspondant pas à la région de diminution de la puissance ; et à mettre en correspondance des données de liaison descendante avec le premier bloc de transmission et le second bloc de transmission, respectivement, le premier bloc de transmission étant transmis avec la puissance attribuée à la région de diminution de la puissance, et le second bloc de transmission étant transmis avec la puissance attribuée à la région autre que la région de diminution de puissance.
(KO)본 발명은 무선 통신 시스템에서 상향링크 전송과 하향링크 전송 사이에 간섭을 감소 시키기 위해, 기지국이 하향링크 신호를 전송하는 방법을 개시한다. 특히, 상기 방법은 하향링크 전송 전력을 다른 영역에 비해 낮춰서 전송하는, 전력 감소 영역을 설정하는 단계; 상기 전력 감소 영역에 대응하는 제 1 전송 블록과 상기 전력 감소 영역에 대응하지 않는 제 2 전송 블록을 구분하여, 생성하는 단계; 하향링크 데이터를 상기 제 1 전송 블록 및 상기 제 2 전송 블록 각각에 맵핑하는 단계; 및 상기 제 1 전송 블록을 상기 전력 감소 영역에 할당된 전력으로 전송하고, 상기 제 2 전송 블록을 상기 전력 감소 영역 이외의 영역에 할당된 전력으로 전송하는 것을 특징으로 한다.
