Abstract:
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.
Abstract:
Methods and apparatus for multiple user uplink are provided. In one aspect, method for wireless communication includes receiving an assignment of a frequency bandwidth for an uplink transmission of a station. The method further includes determining whether a portion of the assigned frequency bandwidth is unavailable for the uplink transmission. The method further includes selectively transmitting the uplink transmission based on whether the portion of the assigned frequency bandwidth is unavailable.
Abstract:
A method of wirelessly communicating a packet including a first portion for transmission over a channel of a first transmission type and a second portion for transmission over a channel of a second transmission type. In one aspect, the method includes generating a first signal field indicative of a channel assignment to the first transmission type. The method further includes generating a second signal field indicative of a channel assignment to the second transmission type. The method further includes transmitting, at a same time, the first signal field duplicated over each channel of the first transmission type, and the second signal field duplicated over each channel of the second transmission type.
Abstract:
A method includes generating a data packet at a source device for transmission via an Institute of Electrical and Electronics Engineers 802.11 wireless network. The data packet includes multiple data symbols that are duplicated in the data packet. At least a portion of a preamble of the data packet is not duplicated in the data packet. The portion of the preamble indicates that the packet is a low rate mode packet. The method also includes transmitting the data packet from the source device to a destination device via the wireless network.
Abstract:
Se divulgan métodos, dispositivos y productos de programas informáticos para mejorar el diseño de campo de capacitación en paquetes con mayor duración de símbolos. En un aspecto, se divulga un método para transmitir un paquete en una red de comunicación inalámbrica. El método incluye transmitir un preámbulo del paquete a través de uno o más transmisiones de espacio-tiempo, el preámbulo, incluidos uno o más campos de entrenamiento configurados para ser utilizados para la estimación de canales, uno o más campos de entrenamiento que comprenden uno o más símbolos de un primero Duración del símbolo. El método incluye además transmitir una carga útil del paquete sobre uno o más transmisiones espaciales, la carga útil que comprende uno o más símbolos de una segunda duración del símbolo, la segunda duración del símbolo mayor que la primera duración del símbolo.

Abstract:
Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes receiving (1110), at a first wireless device, a reference signal (700, 760) from an associated access point (I 04, 204A, 204B, 204C, 304A, 304B, 304C, 3040, 504), the reference signal indicative of a time of joint transmission with at least a second wireless device. The method further includes transmitting (1120) a first communication to the access point based on the reference signal, the communication utilizing a first subset of wireless frequencies available for use. The first communication is concurrent with a second communication, from the second wireless device, utilizing a second subset of wireless frequencies, the second subset excluding the first subset.
