Title (EN) SYSTEMS AND METHODS FOR WIRELESS TRANSMISSION DURING CHANNEL AVAILABILITY CHECK ON MIXED DFS CHANNELS
(FR) SYSTÈMES ET PROCÉDÉS DESTINÉS À LA TRANSMISSION SANS FIL PENDANT UNE VÉRIFICATION DE DISPONIBILITÉ DE CANAL SUR DES CANAUX DFS MÉLANGÉS
Abstract:
(EN) Systems, methods, and apparatuses for wireless transmission during Channel Availability Check on mixed DFS channels are provided. One aspect of this disclosure provides a method of wireless communication. The method includes identifying, at a first device, a plurality of subchannels of the transmission channel for transmission, the identified plurality of subchannels including one or more restricted subchannels and including one or more unrestricted subchannels. The method further includes determining, at the first device, a first bandwidth configuration for the identified restricted subchannels and a second bandwidth configuration for the identified unrestricted subchannels. The method further includes scanning, at the first device, for one or more restricted signals over one or more of the identified restricted subchannels. The method further includes transmitting, at the first device, a beacon to a second device within a duration of the scanning, the beacon being transmitted over one or more of the identified unrestricted subchannels.
(FR) La présente invention concerne des systèmes, des procédés et des appareils de transmission sans fil pendant une vérification de disponibilité de canal sur des canaux DFS mélangés. Un aspect de la présente invention concerne un procédé de communication sans fil. Le procédé comprend l’identification, au niveau d'un premier dispositif, d’une pluralité de sous-canaux du canal de transmission destiné à la transmission, la pluralité identifiée de sous-canaux comprenant un ou plusieurs sous-canaux restreints et comprenant un ou plusieurs sous-canaux non restreints. Le procédé comprend en outre la détermination, au niveau du premier dispositif, d’une première configuration de bande passante destinée aux sous-canaux restreints identifiés et d’une seconde configuration de bande passante destinée aux sous-canaux non restreints identifiés. Le procédé comprend en outre le balayage, au niveau du premier dispositif, d’un ou plusieurs signaux restreints sur un ou plusieurs des sous-canaux restreints identifiés. Le procédé comprend en outre en la transmission, au niveau du premier dispositif, d'une balise vers un second dispositif pendant une durée du balayage, la balise étant transmise sur un ou plusieurs des sous-canaux non restreints identifiés.
