Title
(EN) PHYSICAL LAYER (PHY) DATA UNIT FORMAT FOR HYBRID AUTOMATIC REPEAT REQUEST (HARQ)
(FR) FORMAT D'UNITÉ DE DONNÉES DE COUCHE PHYSIQUE (PHY) POUR DEMANDE DE RÉPÉTITION AUTOMATIQUE HYBRIDE (HARQ)
Abstract
(EN)
A communication device generates one or more physical layer (PHY) PHY protocol service data units (PSDUs) of a PHY data unit, and individually encodes PSDUs of the one or more PSDUs. The communication device generates a PHY preamble of the PHY data unit, including: generating a first signal field in the PHY preamble, and including in the first signal field an indicator to indicate that the PHY preamble includes a second signal field with HARQ information regarding the PHY data unit, and generating the second signal field to include one or more indications of one or more durations of the one or more respective PSDUs within a PHY data portion of the PHY data unit.

L'invention concerne un dispositif de communication qui génère une ou plusieurs unités de données de service de protocole (PSDU) de couche physique PHY (PHY) d'une unité de données PHY, et code individuellement des PSDU d'une ou de plusieurs PSDU. Le dispositif de communication génère un préambule PHY de l'unité de données PHY, comprenant : la génération d'un premier champ de signal dans le préambule PHY, et comprenant dans le premier champ de signal un indicateur afin d'indiquer que le préambule PHY comprend un second champ de signal avec des informations HARQ concernant l'unité de données PHY, et la génération du second champ de signal afin d'inclure une ou plusieurs indications d'une ou plusieurs durées d'une ou de plusieurs PDU respectives à l'intérieur d'une partie de données PHY de l'unité de données PHY.
