Abstract
(EN)
A first communication device generates a null data packet (NDP) announcement (NDPA) frame to announce a subsequent transmission of one or more NDPs to one or more second communication devices as part of a ranging measurement procedure. The NDPA frame is generated to include a training signal repetition field that specifies a number of instances of a training signal to be included in the one or more NDPs. The first communication device transmits the NDPA frame as part of the ranging measurement procedure. The first communication device generates at least one NDP to include a number of instances of the training signal that equals the number of instances of the training signal indicated by the training signal repetition field in the NDPA, and after transmitting the NDPA frame, transmits the at least one NDP as part of the ranging measurement procedure.

Selon l'invention, un premier dispositif de communication génère une trame d'annonce (NDPA) de paquet de données nul (NDP) pour annoncer une transmission ultérieure d'un ou plusieurs NDPs à un ou plusieurs seconds dispositifs de communication en tant que partie d'une procédure de mesure de télémétrie. La trame NDPA est générée pour inclure un champ de répétition de signal d'entraînement qui spécifie un nombre d'instances d'un signal d'entraînement à inclure dans lesdits un ou plusieurs NDPs. Le premier dispositif de communication transmet la trame NDPA en tant que partie de la procédure de mesure de distance. Le premier dispositif de communication génère au moins un NDP pour inclure un nombre d'instances du signal d'entraînement qui est égal au nombre d'instances du signal d'entraînement indiqué par le champ de répétition de signal d'entraînement dans la NDPA, et après la transmission de la trame NDPA, transmet ledit au moins un NDP en tant que partie de la procédure de mesure de télémétrie.
