    Abstract: A method for high efficiency wireless communication is provided. In one aspect, a method (1900) of high efficiency wireless communication includes generating (1902), at an access point, a message for transmission over at least one channel. The message includes a first signal field indicative of a length of the first message after the first signal field. The message further includes a second signal field indicative of at least one channel assignment. The second signal field has a length based on a minimum allocation size. The method further includes transmitting (1904) the message to one or more wireless devices. Figure 19

    Abstract: Methods, devices, and computer program products for improving training field design in packets with increased symbol durations are disclosed. In one aspect, a method of transmitting a packet on a wireless communication network is disclosed. The method includes transmitting a preamble of the packet over one or more space-time-streams, the preamble including one or more training fields configured to be used for channel estimation, the one or more training fields each comprising one or more symbols of a first symbol duration. The method further includes transmitting a payload of the packet over the one or more space-time-streams, the payload comprising one or more symbols of a second symbol duration, the second symbol duration greater than the first symbol duration, wherein the one or more symbols of the second symbol duration are each separated from each other by a cyclic prefix of a third duration, and wherein the first symbol duration is determined based at least in part on the third duration.

    Abstract: Systems, methods, and devices for wireless communication arc disclosed herein. One aspect of the disclosure provides a method of transmitting to two or more wireless communication devices. The method includes transmitting (3105) 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 (3110) 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 (3115) data to the two or more wireless communication devices simultaneously, the data contained on two or more sub-bands.
