(FR) PAQUETS À MIDAMBULES AYANT DES SYMBOLES OFDM COMPRIMÉS
Abstract:
(EN) A communication device generates: i) a physical layer (PHY) preamble of a PHY protocol data unit (PPDU), ii) a first portion of a PHY data payload of the PPDU, and iii) a second portion of the PHY data payload. The PHY preamble includes a first training field, and one or more second training fields. The first portion of the PHY data payload and the second portion of the PHY data payload include a plurality of first orthogonal frequency division multiplexing (OFDM) symbols. Each of multiple first OFDM symbols has a first duration. The communication device generates a PHY midamble of the PPDU to be included between the first and second portions of the PHY data payload. The PHY midamble includes one or more third training fields, each including a respective second OFDM symbol having a second duration shorter than the first duration.
(FR) L'invention concerne un dispositif de communication qui génère : i) un préambule de couche physique (PHY) d'une unité de données de protocole PHY (PPDU), ii) une première partie d'une charge utile de données PHY de la PPDU, et iii) une seconde partie de la charge utile de données PHY. Le préambule PHY comprend un premier champ d'apprentissage, et un ou plusieurs deuxièmes champs d'apprentissage. La première partie de la charge utile de données PHY et la seconde partie de la charge utile de données PHY comprennent une pluralité de premiers symboles de multiplexage par répartition orthogonale de la fréquence (OFDM). Chacun des multiples premiers symboles OFDM a une première durée. Le dispositif de communication génère un midambule PHY de la PPDU à inclure entre les première et seconde parties de la charge utile de données PHY. Le midambule PHY comprend un ou plusieurs troisièmes champs d'apprentissage, comprenant chacun un second symbole OFDM respectif ayant une seconde durée plus courte que la première durée.
