Abstract:
(EN) The present disclosure is research (No.GK17N0100, Millimeter-wave 5G Mobile Communication System Development) having been performed with support from "The Cross-Ministry Giga KOREA Project" funded by the government (Ministry of Science and ICT) in 2017. Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety related services, and the like) on the basis of 5G communication technology and IoT-related technology. According to the present invention, a method by which a transmitter transmits data comprises a step of transmitting a data packet to a receiver, receiving hybrid ARQ (HARQ) feedback information based on a decoded result of the data packet, generating a data packet to be re-transmitted on the basis of the HARQ feedback information, and transmitting, to the receiver, the data packet to be re-transmitted, wherein the HARQ feedback information can include acknowledgment (ACK) or negative-acknowledgment (NACK) and information indicating a HARQ state of the data packet.
(FR) La présente invention se rapporte à la recherche (No.GK17N0100, Millimeter-wave 5G Mobile Communication System Development (Développement d'un système de communications mobiles 5G à ondes millimétriques)) exécutée en 2017 avec le soutien du « The Cross-Ministry Giga KOREA Project » financé par le gouvernement (Ministry of Science and ICT). L'invention propose une technique de communication visant à fusionner, avec une technologie IoT, un système de communication 5G apte à prendre en charge un débit de transmission de données supérieur à celui d'un système 4G. L'invention concerne également un système associé. L'invention peut être appliquée à des services intelligents (par exemple une habitation intelligente, un bâtiment intelligent, une ville intelligente, une voiture intelligente ou une voiture connectée, des soins de santé, l'enseignement numérique, le commerce de détail, les services liés à la sécurité et à la sûreté, etc.) sur la base de la technologie de communication 5G et de technologies associées à l'IoT. Selon la présente invention, un procédé par lequel un émetteur transmet des données, comprend les étapes consistant à : transmettre un paquet de données à un récepteur ; recevoir des informations de rétroaction HARQ (requête automatique de répétition hybride), sur la base d’un résultat décodé du paquet de données ; générer un paquet de données devant être retransmis, sur la base des informations de rétroaction HARQ ; et transmettre, au récepteur, le paquet de données devant être retransmis, les informations de rétroaction HARQ pouvant comprendre un accusé de réception (ACK) ou un accusé de réception négatif (NACK) et des informations indiquant un état HARQ du paquet de données.
(KO) 본 개시는 2017년도 정부(과학기술정보통신부)의 재원으로 '범부처 Giga KOREA 사업'의 지원을 받아 수행된 연구이다(No.GK17N0100, 밀리미터파 5G 이동통신 시스템 개발). 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 발명에 따르면 송신기가 데이터를 전송하는 방법에 있어서, 수신기로 데이터 패킷을 전송하고, 상기 데이터 패킷의 복호 결과를 기반으로 한 하이브리드 ARQ (hybrid ARQ, HARQ) 피드백(feedback) 정보를 수신하고, 상기 HARQ 피드백 정보를 기반으로 재전송할 데이터 패킷을 생성하고, 상기 재전송할 데이터 패킷을 상기 수신기로 전송하는 단계를 포함하며, 상기 HARQ 피드백 정보는 수신 긍정 확인 (acknowledgment, ACK) 또는 수신 부정 확인 (negative-acknowledgment, NACK) 및 상기 데이터 패킷의 HARQ 상태를 지시하는 정보를 포함할 수 있다.
