    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: Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.

    Abstract: Methods, devices, and computer program products for transmitting and receiving discovery and paging messages are described herein. In one aspect, an apparatus operable in a wireless communication system includes a transmitter and receiver. The transmitter transmits a discovery packet during a first discovery interval of a plurality of discovery intervals. The discovery packet advertises a service provided in a wireless communications network, and the plurality of discovery intervals include recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets. The receiver receives a paging packet from a first device during a first paging interval of a plurality of paging intervals. The paging packet indicates interest in the service, and the plurality of paging intervals include recurring time intervals when the plurality of devices are configured to transmit and receive paging packets. The plurality of paging intervals do not overlap the plurality of discovery intervals.

    Abstract: SOLICITAÇÃO PARA ENVIO (RTS) E LIBERAÇÃO DE ENVIO (CTS) PARA OPERAÇÕES DE MULTICANAL. Determinados aspectos da presente descrição proveem técnicas e aparelho para sinalizar a largura de banda a ser utilizada para comunicações sem fio utilizando uma permuta de quadro RTS/CTS (Solicitação de Envio/Liberação de Envio), provendo larguras de banda de pelo menos 20 MHz, 80 MHz, 160 MHz, ou mais. Essa permuta de informação de largura de banda pode ser realizada implicitamente - pela determinação dos canais nos quais os quadros RTS/CTS são na verdade enviados - ou explicitamente. Em adição a essa permuta de informação de largura de banda, os aspectos da presente descrição também podem permitir a proteção de Vetor de Alocação de Rede (NAV) em múltiplos canais. Dessa forma, o meio sem fio pode ser reservado, e a transmissão pode ser protegida contra nós ocultos.
