Abstract
(EN)
In a wireless local area network (LAN) system, a transmission station (STA) may transmit, to a receiving STA, a PHY protocol data unit (PPDU) including a first redundancy version of transmission data. On the basis of whether an acknowledgement (ACK) or negative ACK (NACK) frame is received within a threshold time, the transmission STA may determine a second redundancy version of the transmission data to be retransmitted.
(FR)
Dans un système de réseau local (LAN) sans fil, une station (STA) de transmission peut transmettre à une STA de réception une unité de données de protocole PHY (PPDU) contenant une première version de redondance de données de transmission. Selon qu'une trame d'accusé de réception (ACK) ou d'ACK négatif (NACK) est reçue pendant une durée de seuil, la STA de transmission peut déterminer une seconde version de redondance des données de transmission devant être retransmises.
(KO)
무선랜(Wireless Local Area Network) 시스템에서, 송신 STA(station)은 송신 데이터의 제1 리던던시 버전(redundancy version)을 포함하는 PPDU(PHY protocol data unit)를 수신 STA에게 전송할 수 있다. 상기 송신 STA은 임계 시간 내에 ACK(acknowledgement) 또는 NACK(negative ACK) 프레임의 수신 여부에 기초하여 재전송할 상기 송신 데이터의 제2 리던던시 버전을 결정할 수 있다.
