Abstract:
(EN) The present specification provides a method for receiving data on the basis of quasi co-location (QCL) in a wireless communication system. More particularly, a data reception method performed by means of a terminal comprises the steps of: receiving transmission configuration indication (TCI) state information relating to at least one QCL indication with respect to a downlink reference signal (DL RS) from a base station by means of RRC signaling; receiving a physical downlink control channel (PDCCH), comprising downlink control information (DCI), on a first slot from the base station; and receiving a physical downlink shared channel (PDSCH) comprising data from the base station on the basis of one or more QCL indications. Therefore, the flexibility of the terminal during beam switching can be enhanced.
(FR) La présente invention concerne un procédé de réception de données sur la base d'une quasi-colocalisation (QCL) dans un système de communication sans fil. Plus particulièrement, un procédé de réception de données mis en œuvre au moyen d'un terminal comprend les étapes consistant à : recevoir des informations d'état d'indication de configuration de transmission (TCI) concernant au moins une indication QCL par rapport à un signal de référence de liaison descendante (DL RS) provenant d'une station de base au moyen d'une signalisation RRC; recevoir un canal de commande de liaison descendante physique (PDCCH), comprenant des informations de commande de liaison descendante (DCI), sur un premier intervalle à partir de la station de base; et recevoir un canal partagé de liaison descendante physique (PDSCH) comprenant des données provenant de la station de base sur la base d'une ou de plusieurs indications de QCL. Par conséquent, la flexibilité du terminal pendant la commutation de faisceau peut être améliorée.
(KO) 본 명세서는 무선 통신 시스템에서 QCL(quasi-co location)에 기초하여 데이터를 수신하는 방법을 제공한다. 보다 구체적으로, 단말에 의해 수행되는 상기 데이터 수신 방법은, 적어도 하나의 DL RS(downlink reference signal)에 대한 QCL 지시(indication)와 관련된 TCI(transmission configuration indication) 상태(state) 정보를 RRC 시그널링을 통해 기지국으로부터 수신하는 단계; DCI(downlink control information)를 포함하는 PDCCH(physical downlink control channel)를 제 1 슬롯(slot)에서 상기 기지국으로부터 수신하는 단계; 및 하나 또는 그 이상의 QCL indication들에 기초하여 상기 데이터를 포함하는 PDSCH(physical downlink shared channel)를 상기 기지국으로부터 수신하는 단계를 포함한다. 이를 통해, 빔 스위칭 시 단말의 구현 유연성(flexibility)를 높일 수 있는 효과가 있다.
