Abstract: front page image
(EN) Systems, methods, and devices for wireless communication are disclosed herein. One aspect of the disclosure provides a method of transmitting to two or more wireless communication devices. The method includes transmitting a first section of a preamble according to a first format, the first section of the preamble containing information informing devices compatible with the first format to defer to the transmission, transmitting a second section of the preamble according to a second format, the second section of the preamble containing tone allocation information, the tone allocation information identifying two or more wireless communication devices; and transmitting data to the two or more wireless communication devices simultaneously, the data contained on two or more sub-bands.
(FR) L'invention concerne des systèmes, des procédés et des dispositifs de communication sans fil. Un aspect de l'invention concerne un procédé de transmission à deux ou plusieurs dispositifs de communication sans fil. Le procédé consiste à transmettre, dans un premier format, une première section d'un préambule contenant des informations qui informent des dispositifs compatibles avec le premier format de différer la transmission; à transmettre, dans un second format, une seconde section du préambule contenant des informations d'attribution de tonalité qui identifient deux ou plusieurs dispositifs de communication sans fil; et à transmettre simultanément auxdits deux ou plusieurs dispositifs de communication sans fil des données contenues dans deux ou plusieurs sous-bandes.
