Title (EN) METHOD AND APPARATUS FOR PERFORMING HYBRID AUTOMATIC REPEAT REQUEST IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR EFFECTUER UNE DEMANDE AUTOMATIQUE DE RÉPÉTITION HYBRIDE DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract:
(EN) The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and an apparatus for performing a Hybrid automatic repeat request (HARQ) for reducing latency in wireless communication systems are provided. The method includes receiving a concatenated packet including a short transmission time interval (TTI) packet and a long TTI packet from a transmitter, decoding the short TTI packet, feeding, when decoding the short TTI packet fails, a negative acknowledgement (NACK) back to the transmitter, and receiving a retransmission packet including the short TTI packet and the long TTI packet from the transmitter.
(FR) La présente invention concerne un système de communication antérieur à la 5ième génération (5G) ou de la 5G, qui est destiné à prendre en charge un système de communication postérieur à la 4ième génération (4G) à débits de données plus élevés, tel qu'un système à évolution à long terme (LTE). L'invention concerne également un procédé et un appareil pour effectuer une demande automatique de répétition hybride (HARQ) pour réduire la latence dans des systèmes de communication sans fil. Le procédé consiste à recevoir un paquet concaténé comprenant un paquet d'intervalle de temps de transmission (TTI) court et un paquet TTI long provenant d'un émetteur, à décoder le paquet TTI court, à renvoyer, lorsque le décodage du paquet TTI court échoue, un accusé de réception négatif (NACK) à l'émetteur et à recevoir un paquet de retransmission comprenant le paquet TTI court et le paquet TTI long de l'émetteur.
