    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 particular method includes transmitting a frame (120) from a station (110, 112, 114, 116, 202, 302, 402) to an access point (102, 104, 106, 202, 204, 304, 404, 600). The frame includes a beacon sequence number (127, 206) related to a configuration of the access point. The method also includes, in response to transmitting the frame, receiving an update frame from the access point. The update frame indicates at least one change in the configuration of the access point (102, 104, 106, 202, 204, 304, 404, 600).

    Abstract: In order to address the issue of increasing bandwidth requirements that are demanded for wireless communications systems, different schemes are being developed to allow multiple user terminals to communicate with a single access point by sharing the channel resources while achieving high data throughputs. With limited communication resources, it is desirable to reduce the amount of traffic passing between the access point and the multiple terminals. For example, when multiple terminals send uplink communications to the access point, it is desirable to minimize the amount of traffic to complete the uplink of all transmissions. Thus, there is a need for an improved protocol for uplink transmissions from multiple terminals. Methods and apparatus for acknowledgment of multiple user uplink are provided. In one aspect, a method of wireless communication includes receiving a first wireless message from a first station at least partially concurrently with receiving a second wireless message from a second station, generating a first acknowledgment message in response to receiving the first wireless message, generating a second acknowledgement message in response to receiving the second wireless message, and transmitting the first acknowledgment message to the first station at least partially concurrently with transmitting the second acknowledgement message to the second station.
