Title (EN) UPLINK POWER CONTROL METHOD AND USER EQUIPMENT
(FR) PROCÉDÉ DE COMMANDE DE PUISSANCE DE LIAISON MONTANTE ET ÉQUIPEMENT UTILISATEUR
(KO) 상향링크 전력제어 방법 및 사용자기기
Abstract: front page image
(EN)The present invention relates to an uplink power control method and user equipment, which involve determining a power correction factor by considering the number of antenna ports. According to the present invention, even when a base station transmits the same power control information to the user equipment, the user equipment maps the power control information to another power correction factor and determines an uplink transmission power depending on an uplink transmission condition. Thus, uplink power control can be performed in a more efficient manner.
(FR)La présente invention porte sur un procédé de commande de puissance de liaison montante et sur un équipement utilisateur (UE), qui impliquent de déterminer un facteur de correction de puissance par considération du nombre de ports d'antenne. Selon la présente invention, même lorsqu'une station de base (BS) envoie les mêmes informations de commande de puissance à l'équipement utilisateur, l'équipement utilisateur fait correspondre les informations de commande de puissance à un autre facteur de correction de puissance et détermine une puissance d'émission de liaison montante en fonction d'une condition de transmission en liaison montante. Une commande de puissance de liaison montante peut ainsi être réalisée d'une manière plus efficace.
(KO)본 발명의 상향링크 전력제어와 사용자기기는 안테나 포트의 개수를 고려하여 전력 보정 인자를 결정한다. 본 발명에 의하면, 기지국이 동일한 전력 제어 정보를 사용자기기에 전송하더라도 상기 사용자기기는 상향링크 전송 상황에 따라 상기 전력 제어 정보를 다른 전력 보정 인자에 맵핑하여 상향링크 전송전력을 결정할 수 있다. 이에 따라, 보다 효율적인 상향링크 전력제어가 가능해진다.
