Abstract
(EN)
Systems, methods, and devices for dynamic transmission power control are provided. One aspect provides a method of wireless communication that includes, at a wireless device, transmitting, at a first power level, a first message to an access point and receiving one or more packets from the access point and a plurality of stations. The method further includes, based on the one or more packets, identifying first and second sets of stations of the plurality of stations, the sets including a first and second station, respectively. The method further includes, after identifying the first and second sets of stations, receiving an additional packet from the access point, the additional packet identifying the second station. The method further includes, in response to receiving the additional packet, transmitting, at a second power level, a second message to the first station, the second power level being less than the first power level.

La présente invention concerne des systèmes, des procédés et des dispositifs destinés à la commande de puissance de transmission dynamique. Un aspect concerne un procédé de communication sans fil qui comprend, au niveau d'un dispositif sans fil, la transmission, à un premier niveau de puissance, d'un premier message à un point d'accès et la réception d'un ou plusieurs paquets en provenance du point d'accès et d'une pluralité de stations. Le procédé consiste en outre, en fonction du ou des paquets, à identifier des premier et second ensembles de stations de la pluralité de stations, les ensembles comprenant une première et une seconde station, respectivement. Le procédé consiste en outre, après identification des premier et second ensembles de stations, à recevoir un paquet supplémentaire en provenance du point d'accès, le paquet supplémentaire identifiant la seconde station. Le procédé consiste en outre, en réponse à la réception du paquet supplémentaire, à transmettre à un second niveau de puissance, un second message à la première station, le second niveau de puissance étant inférieur au premier niveau de puissance.
