Title
(EN) DETERMINING NUMBER OF MIDAMBLES IN A PACKET

Abstract
(EN)
A communication device receives a physical layer (PHY) protocol data unit (PPDU). The PPDU includes i) a PHY preamble and ii) PHY data portion that includes one or more PHY midambles, and the PHY preamble includes i) an indication of a length of the PPDU, typically in the L-SIG field, and ii) an indication of a periodicity of PHY midambles in the PHY data portion, for instance as a new field within the HE- SIG-A field. The communication device calculates a number of PHY midambles in the PPDU using i) the indication of the length of the PPDU, and ii) the indication of the periodicity of PHY midambles. The communication device calculates a reception time for the PPDU using the calculated number of PHY midambles, and processes the PPDU using the calculated reception time.

L'invention concerne un dispositif de communication qui reçoit une unité de données de protocole de couche physique (PHY) (PPDU). La PPDU comprend i) un préambule PHY et ii) une partie de données PHY qui comprend un ou plusieurs mi-ambules PHY, et le préambule PHY comprend i) une indication d'une longueur de la PPDU, typiquement dans le champ L-SIG, et ii) une indication d'une périodicité de mi-ambules PHY dans la partie de données PHY, par exemple en tant que nouveau champ dans le champ HE-SIG-A. Le dispositif de communication calcule un nombre de mi-ambules PHY dans la PPDU à l'aide de i) l'indication de la longueur de la PPDU, et ii) l'indication de la périodicité des mi-ambules PHY. Le dispositif de communication calcule un temps de réception pour la PPDU à l'aide du nombre calculé de mi-ambules PHY, et traite la PPDU à l'aide du temps de réception calculé.
