    Abstract: Un procedimiento (3000) de comunicación a través de una red de comunicación inalámbrica, estando caracterizado el procedimiento por: determinar (3010) un ancho de banda total para una transmisión de un mensaje de acuerdo con una primera especificación, comprendiendo el ancho de banda total una pluralidad de tonos, donde una parte del ancho de banda total está ocupada por una transmisión de acuerdo con una segunda especificación diferente de la primera especificación; dividir de forma lógica (3020) la pluralidad de tonos en una pluralidad de tonos utilizables y en una pluralidad de tonos de guarda y una pluralidad de tonos de corriente continua para formar un plan de tonos que conserve al menos un límite físico de acuerdo con la segunda especificación; dividir de forma lógica (3030) la pluralidad de tonos utilizables en una pluralidad de unidades de recursos; donde dividir de forma lógica la pluralidad de tonos utilizables en la pluralidad de unidades de recursos comprende asignar una cantidad de tonos de la pluralidad de tonos que no están en ninguna unidad de recursos en uno o más de un bloque central, un bloque central izquierdo y un bloque central derecho; determinar (3040) una indicación, donde la indicación asigna y vincula los canales de al menos dos de la pluralidad de unidades de recursos a un dispositivo de comunicación inalámbrica de una pluralidad de dispositivos de comunicación inalámbrica, donde la indicación no asigna la parte del ancho de banda total que está ocupada por la transmisión de acuerdo con la segunda especificación; donde la indicación asigna además al menos una parte de uno del bloque central, el bloque central izquierdo y el bloque central derecho al dispositivo de comunicación inalámbrica de la pluralidad de dispositivos de comunicación inalámbrica; y transmitir (3050) la indicación a la pluralidad de dispositivos de comunicación inalámbrica.

    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for managing high volumes of space-time-streams in Wi-Fi systems. An access point (AP) may transmit packets including long training field (LTF) sections using a number of space-time-streams greater than eight. Mobile stations (STAs) in the system may or may not be capable of processing this number of streams. The AP may modulate an LTF section using a matrix with dimensions smaller than the number of streams by using tone-interleaving or by performing modulation with separate matrices in time and frequency. In some other implementations, the AP may split the antennas for transmission into groups, each group transmitting either different packets in a subset of streams or a same packet in a subset of tones. In further implementations, the AP may combine multiple space-time-streams into a super stream that supports reception at different types of STAs.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, an apparatus is configured to transmit user data in a first symbol of a first symbol type. The first symbol type has a first symbol duration, a first frequency bandwidth, and a first tone plan. The first tone plan includes a first valid start tone index, a first valid end tone index, and a first set of DC tones. The apparatus is further configured to transmit an LTF in a second symbol of a second symbol type. The second symbol type has a second symbol duration, a second frequency bandwidth, and a second tone plan. The second tone plan includes a second valid start tone index, a second valid end tone index, and a second set of DC tones.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device, such as a device in a wireless local area network, may use a radio frame structure that includes a high efficiency (HE) signal field and an HE data field for communications, for example, over shared radio frequency spectrum. One or more bits or symbols within the HE signal field may be adjusted to avoid a high peak-to-average power ratio (PAPR). In some cases, the adjustment may be to a signal A (SIG-A) or signal B (SIG-B) field. In some examples, a random bit sequence may be used for padding in a signal field. In other examples, bits may be reversed or scrambled. In yet other examples, bits may be modulated and a phase rotation may be applied to the corresponding signal.
