Summary:The present disclosure relates to a communication technique that merges IoT technology with a 5G communication system for supporting higher data transmission rates than 4G systems, and a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The invention of the present disclosure is a method performed by a terminal of a communication system, the method being characterized by comprising: receiving physical uplink control channel (PUCCH) setting information from a base station; receiving a downlink control channel (DCI) which schedules downlink data from the base station; receiving the downlink data; and repeatedly transmitting, to the base station, hybrid automatic repeat request acknowledgement (HARQ-ACK) information for the downlink data on the PUCCH, wherein the PUCCH setting information includes at least one piece of information among a plurality of PUCCH formats for repeatedly transmitting the PUCCH, a set of one or more start symbols, a set of one or more numbers of PUCCH symbols; and the total number of slots or symbols for finishing the PUCCH repetition. La présente invention concerne une technique de communication qui permet de fusionner la technologie IdO avec un système de communication 5G pour prendre en charge des débits de transmission de données supérieurs à ceux des systèmes 4G, ainsi qu'un système s'y rapportant. La présente invention peut s'appliquer à des services intelligents (par exemple, des maisons intelligentes, des immeubles intelligents, des villes intelligentes, des voitures intelligentes ou des voitures connectées, les soins de santé, l'éducation numérique, le commerce de vente au détail, des services de sécurité et de sûreté, et analogues) sur la base d'une technologie de communication 5G et d'une technologie liée à l'IdO. La présente invention concerne un procédé mis en oeuvre par un terminal d'un système de communication, le procédé étant caractérisé en ce qu'il comprend: la réception d'information d'établissement d'un canal de commande de liaison montante physique (PUCCH) provenant d'une station de base; la réception d'un canal de commande de liaison descendante (DCI) qui ordonnance des données de liaison descendante provenant de la station de base; la réception des données de liaison descendante; et la transmission répétée, vers la station de base, d'information d'accusé de réception de demande de répétition automatique hybride (HARQ-ACK) pour les données de liaison descendante sur le PUCCH, l'information d'établissement de canal PUCCH comprenant au moins un élément d'information parmi une pluralité de formats de canal PUCCH pour la transmission répétée du canal PUCCH, d'un ensemble d'un ou plusieurs symboles de départ, d'un ensemble d'un ou plusieurs nombres de symboles de canal PUCCH; et du nombre total d'intervalles de temps ou de symboles pour compléter la répétition de canal PUCCH. 본 개시는 4G 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G 통신 시스템을 IoT 기술과 융합하는 통신 기법 및 그 시스템에 관한 것이다. 본 개시는 5G 통신 기술 및 IoT 관련 기술을 기반으로 지능형 서비스 (예를 들어, 스마트 홈, 스마트 빌딩, 스마트 시티, 스마트 카 혹은 커넥티드 카, 헬스 케어, 디지털 교육, 소매업, 보안 및 안전 관련 서비스 등)에 적용될 수 있다. 본 개시의 발명은 통신 시스템의 단말이 수행하는 방법에 있어서, 기지국으로부터 PUCCH (physical uplink control channel) 설정 정보를 수신하고, 상기 기지국으로부터 하향링크 데이터를 스케줄링하는 DCI(downlink control channel)을 수신하고, 상기 하향링크 데이터를 수신하고, 상기 기지국으로 상기 하향링크 데이터에 대한 HARQ-ACK (hybrid automatic repeat request acknowledgement) 정보를 PUCCH 상에서 반복 전송하고, 상기 PUCCH 설정 정보는 PUCCH 반복 전송을 수행하기 위한 복수의 PUCCH 포맷, 하나 이상의 시작 심볼의 집합, 하나 이상의 PUCCH 심볼의 수의 집합, PUCCH 반복을 종료하기 위한 총 슬롯 또는 총 심볼의 수 중 적어도 하나의 정보를 포함하는 것을 특징으로 한다.
