Title
(EN) METHOD AND APPARATUS FOR SAVING POWER OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL PERMETTANT D'ÉCONOMISER L'ÉNERGIE D'UN TERMINAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선 통신 시스템에서 단말의 전력 절약을 위한 방법 및 장치
Abstract
(EN) Disclosed is a method by which a terminal controls monitoring of a physical downlink control channel (PDCCH), comprising the steps of: receiving, from a base station, configuration information about a power-saving signal; monitoring the power-saving signal received from the base station on the basis of the configuration information about the power-saving signal; determining whether the power-saving signal is detected on the basis of the monitoring; and controlling PDCCH monitoring configurations of the terminal on the basis of a determination result.
(FR) L'invention concerne un procédé au moyen duquel un terminal commande la surveillance d'un canal de commande de liaison descendante physique (PDCCH), comprenant les étapes consistant : à recevoir, d'une station de base, des informations de configuration concernant un signal d'économie d'énergie ; à surveiller le signal d'économie d'énergie reçu de la station de base sur la base des informations de configuration concernant le signal d'économie d'énergie ; à déterminer si le signal d'économie d'énergie est détecté sur la base de la surveillance ; et à commander des configurations de surveillance de canal PDCCH du terminal sur la base d'un résultat de détermination.
(KO) 본 개시는 기지국으로부터 전력 절약 신호에 대한 설정 정보를 수신하는 단계; 상기 전력 절약 신호에 대한 설정 정보에 기초하여 상기 기지국으로부터의 전력 절약 신호의 모니터링을 수행하는 단계; 상기 모니터링에 기초하여 상기 전력 절약 신호가 검출되는지 여부를 판단하는 단계; 상기 판단 결과에 기초하여, 상기 단말의 하향링크 제어 채널(PDCCH)의 모니터링 설정을 제어하는 단계를 포함하는 단말의 하향링크 제어 채널의 모니터링을 제어하는 방법을 개시한다.
