Abstract
(EN) Proposed is a method for performing channel estimation of a physical downlink control channel (PDCCH) in a wireless communication system. Specifically, a method performed by a terminal may comprise the steps of: transmitting, to a base station, terminal capability information related to channel estimation; receiving, from the base station, information on a PDCCH monitoring period; and performing channel estimation on the basis of the information on the PDCCH monitoring period, wherein the terminal capability information includes information on the maximum number of control channel elements (CCEs), channel estimation of which can be performed per PDCCH monitoring period.
(FR) L'invention concerne un procédé pour l'exécution d'une estimation de canal d'un canal physique de commande de liaison descendante (PDCCH) dans un système de communication sans fil. De façon plus spécifique, un procédé exécuté par un terminal peut comprendre les étapes consistant à : transmettre, à une station de base, des informations de capacité de terminal en lien avec une estimation de canal ; recevoir, de la station de base, des informations relatives à une période de surveillance de PDCCH ; et exécuter une estimation de canal sur la base des informations relatives à la période de surveillance de PDCCH. Les informations de capacité de terminal comprennent des informations relatives au nombre maximal d'éléments de canal de commande (CCE) pour lesquels une estimation de canal peut être exécutée dans chaque période de surveillance de PDCCH.
(KO) 무선 통신 시스템에서 물리 하향링크 제어 채널(Physical Downlink Control Channel, PDCCH)의 채널 추정(Channel Estimation)을 수행하기 위한 방법을 제안한다. 구체적으로, 단말에 의해 수행되는 방법은, 상기 채널 추정에 관련한 단말 능력 정보를 기지국으로 전송하는 단계와, PDCCH 모니터링 구간에 대한 정보를 상기 기지국으로부터 수신하는 단계와, 상기 PDCCH 모니터링 구간에 대한 정보에 기반하여 채널 추정을 수행하는 단계를 포함하고, 상기 단말 능력 정보는 PDCCH 모니터링 구간 당 채널 추정 가능한 최대 제어 채널 요소(Control Channel Element, CCE)의 수에 대한 정보를 포함할 수 있다.
