Abstract[English]
A format for a Null Data Packet Announcement (NDPA) frame for Wi-Fi sensing is provided. The frame format is based on the ranging NDPA frame format. The sensing frame can indicate channel state information measurement parameters, for a preamble punctured EHT NDP PPDU, in the Common Info field of the frame. When there is insufficient space in the Common Info field, the puncturing patterns can be indicated in each station (STA) field of the frame. Alternatively, the sensing frame can include an additional Common Info field that includes the information defining the puncturing patterns. Also provided is a method that indicates partial bandwidth (BW) feedback when the BW of each STA is smaller than the BW of the EHT NDP PPDU. A method that indicates the BW of the sensing NDPA frame is also provided, as is a method for setting the signal field in the EHT NDP PPDU for a number of long training field repetition.[French]
Un format pour une trame d'annonce de paquet de données nulles (NDPA) pour une détection Wi-Fi est fourni. Le format de trame est basé sur le format de trame NDPA de télémétrie. La trame de détection peut indiquer des paramètres de mesure d'informations d'état de canal, pour une PPDU NDP EHT perforée de préambule, dans le champ d'informations commun de la trame. Lorsqu'il y a un espace insuffisant dans le champ d'informations commun, les motifs de perforation peuvent être indiqués dans chaque champ de station (STA) de la trame. En variante, la trame de détection peut comprendre un champ d'informations commun supplémentaire qui comprend les informations définissant les motifs de perforation. L'invention concerne également un procédé qui indique une rétroaction de bande passante (BW) partielle lorsque la BW de chaque STA est inférieure à la BW de la PPDU NDP EHT. L'invention concerne également un procédé qui indique la BW de la trame NDPA de détection, ainsi qu'un procédé de réglage du champ de signal dans la PPDU NDP EHT pour un certain nombre de répétitions de champ d'apprentissage long.
