Abstract
(EN)
A method for sending a physical protocol data unit (PPDU) of a station (STA) apparatus in a wireless LAN (WLAN) system according to one embodiment of the present invention comprises: a step of generating a high efficiency-short training field (HE-STF) sequence; a step of generating a PPDU including an HE-STF field configured on the basis of the HE-STF sequence; and a step of sending the PPDU, wherein the HE-STF field included in the PPDU uses frequency resource unit, the HE-STF sequence is mapped to tones included in the frequency resource unit, and any one predefined value from among 1+j, 1-j, -1+j, and -1-j values may be mapped to specific tones having a predetermined index among the tones to which the HE-STF sequence is mapped.

Un mode de réalisation de la présente invention concerne un procédé pour envoyer une unité de données de protocole physique (PPDU) d'un appareil station (STA) dans un système de LAN sans fil (WLAN) qui comprend : une étape consistant à produire une séquence de champ d'entraînement court à haute efficacité (HE-STF); une étape de production d'une PPDU contenant un champ HE-STF configuré en fonction de la séquence de HE-STF; et une étape d'envoi de la PPDU, où le champ HE-STF compris dans la PPDU utilise une unité de ressource de fréquence, la séquence HE-STF est mappée sur des tonalités présentes dans l'unité de ressource de fréquence, et une valeur prédéfinie quelconque parmi les valeurs 1 + j, 1 -j, -1 + j et -1 - j peut être mappée sur des tonalités spécifiques ayant un indice prédéterminé parmi les tonalités sur lesquelles la séquence de HE-STF est mappée.
