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: 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: Method and systems are disclosed for qualifying a wireless device as frequency hopping device. In some aspects, an access point (AP) may determine a frequency hopping pattern for the wireless device, and then allocate a sequence of unique resource units to the wireless device based on the frequency hopping pattern. Each of the unique resource units include a different set of frequency subcarriers. The AP may receive a series of uplink orthogonal frequency-division multiple access (OFDMA) transmissions from the wireless device on the allocated sequence of unique resource units.
