    Abstract: Methods and apparatus for channel state information feedback are provided. In various aspects, a message is transmitted to one or more wireless communication devices requesting channel state information. In some aspects, a first portion of the message is transmitted according to a first or second, and contains first information intended for a first or second set of wireless communication devices compatible with the first or second format respectively. In some aspects, a second portion of the first message is transmitted according to the second format, and contains second information intended for the second set of wireless communication devices compatible with the second format. In some aspects, this information may comprise at least one of a list of identifiers, a set of parameters for estimating the channel state information estimation, and uplink transmission allocation information

    Abstract: Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes exchanging (1210), at an access point (104, 204A, 204B, 204C, 304A, 304B, 304C, 3040, 504), at least one frame reserving a wireless medium with at least one of a first and second wireless device. The method further includes receiving (1220) a first communication on a first set of wireless frequencies from the first wireless device. The method further includes receiving (1230) a second communication, at least partially concurrent with the first communication, on a second set of wireless frequencies from the second wireless device. The method further includes transmitting (1240) at least one acknowledgment of the first and second communication. The first set and the second set are mutually exclusive subsets of a set of wireless frequencies available for use by both the first and second wireless device.

    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.
