Ces dernières années, les réseaux locaux sans fil (WLAN) ont été déployés en étroite collaboration, ce qui signifie qu'ils interfèrent les uns avec les autres. Les stations mobiles (MS) comme les téléphones intelligents qui se connectent à de tels WLAN sont également en augmentation. Dans de tels environnements interférents, la fréquence des interférences radio dépend de la position du MS. De plus, à mesure que les MS et leurs applications se diversifient, les fréquences de génération de trames à partir des MS deviennent également diverses. Ainsi, des possibilités suffisantes de transmission de trames devraient être attribuées aux MS, quelles que soient leurs fréquences d'interférence radio et leurs taux de génération de trames. Une technologie clé pour résoudre ce problème est la transmission à accès multiple par répartition orthogonale de la fréquence (OFDMA) introduite dans la norme IEEE 802.11ax. Cependant, les travaux existants ne prennent pas en compte les différences de fréquences d'interférence et de fréquences de génération de trames entre les MS de manière intégrée. Cet article propose une méthode de transmission de trames de liaison montante pour les environnements WLAN interférents qui utilise efficacement la transmission OFDMA pour attribuer suffisamment d'opportunités de transmission aux MS indépendamment de leurs propres fréquences d'interférence et taux de génération de trames, tout en utilisant efficacement la ressource du canal. Compte tenu du problème combiné, cette méthode proposée alloue des unités de ressources (RU), créées en divisant le canal, aux MS. De plus, sur la base d'une analyse mathématique de la durée de transmission de trame requise, le procédé proposé sélectionne de manière flexible la transmission OFDMA ou la transmission de trame conventionnelle avec CSMA/CA, qui n'est pas non plus prise en compte dans les travaux existants.

Abstract: In recent years, wireless LANs (WLANs) are closely deployed which means they interfere with each other. Mobile stations (MSs) like smart phones that connect to such WLANs are also increasing. In such interfering environments, radio interference frequency depends on MS position. In addition, as MSs and their applications become diverse, frame generation rates from MSs are also becoming various. Thus, sufficient frame transmission opportunities should be assigned to MSs regardless of their radio interference frequencies and frame generation rates. One key technology to deal with this issue is uplink orthogonal frequency division multiple access (OFDMA) transmission introduced in IEEE 802.11ax. However, existing works do not consider the differences of the interference frequencies and frame generation rates among MSs in an integrated manner. This paper proposes an uplink frame transmission method for interfering WLAN environments that effectively uses the OFDMA transmission to assign enough transmission opportunities to MSs regardless of their own interference frequencies and frame generation rates, while efficiently using the channel resource. Considering the combined problem, this proposed method allocates resource units (RUs), created by dividing the channel, to MSs. In addition, based on a mathematical analysis of required frame transmission duration, the proposed method flexibly selects the OFDMA transmission or conventional frame transmission with CSMA/CA, which is also not considered in the existing works.
