    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: A wireless device may selectively add padding to an end of a data transmission in order to provide adequate time for a receiving device to process the transmitted data and transmit feedback related to the transmitted data. A wireless device may identify a total amount of data capable of being transmitted in a transmission, and determine a number of data bits to be transmitted in the transmission. An amount of padding may be selected based on a proportion of the total amount of data capable of being transmitted and the number of data bits. In some examples, a preamble for a feedback transmission may be transmitted concurrently with processing of the received transmission.

    Abstract: Apparatuses for wireless communication are provided. The apparatus includes a processor configured to generate a packet for transmission via a wireless signal. The packet is generated for transmission over a bandwidth of 1 MHz using at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising 32 subcarriers described by indices from -16 to 15, wherein each of the 32 subcarriers has an average constellaton enrgy. The apparatus further includes a transmitter configured to transmit the packet via the wireless signal such that each average constellation energy for subcarries having indices of -8 to -1 and 1 to 8 deviates no more than +-4 dB from an overall average of the average constellation energies over subcarriers having indices of -8 to -1 and 1 to 8, and each average constellation energy for subcarries having indices of -13 to -9 and 9 to 13 deviates no more than +4/-6 dB from the overall average.

    Abstract: Methods and apparatuses for communicating over a wireless communication network are disclosed herein. One example apparatus includes a memory that stores instructions. The apparatus further includes a processor coupled with the memory. The processor and the memory are configured to determine a total bandwidth for a transmission of a message, the total bandwidth including a plurality of tones. The processor is further configured to divide the plurality of tones in the total bandwidth into one or more 26-, 52-, 106-, 242-, or 996-tone blocks. The processor is further configured to determine an indication. The indication assigns one or more of the one or more tone blocks to a first wireless communication device. The apparatus further includes a transmitter configured to transmit the indication to at least the first wireless communication device or a second device.
