Abstract: Systems, methods, and devices for wireless communication are provided. In one aspect, an apparatus for wireless communication is 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. The apparatus further includes a transmitter configured to transmit the packet via the wireless signal having a power spectral density. The power spectral density within +0.45 MHz of a center frequency of the wireless signal is at a first power spectral density level. The power spectral density between 0.45 MHz and 0.6 MHz from the center frequency of the wireless signal and between -0.45 MHz and -0.6 MHz from the center frequency of the wireless signal is less than the first power spectral density level. The power spectral density between 0.6 MHz and 1 MHz from the center frequency of the wireless signal and between -0.6 MHz and -1 MHz from the center frequency of the wireless signal is less than -20 dBr with respect to the first power spectral density level. The power spectral density between 1 MHz and 1.5 MHz from the center frequency of the wireless signal and between -1 MHz and -1.5 MHz from the center frequency of the wireless signal is less than -28 dBr with respect to the first power spectral density level. The power spectral density of greater than +1.5 MHz from the center frequency of the wireless signal is less than -40 dBr with respect to the first power spectral density level.

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.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for partial bandwidth feedback based on punctured sounding. Punctured sounding is used by a transmitting device that omits portions of a channel bandwidth based on a puncturing pattern. The puncturing pattern may be based on an exclusion bandwidth zone to avoid transmissions on portions of channels that may interfere with an incumbent system transmission. The puncturing pattern may be indicated in a null data packet announcement (NDPA) to inform the receiving device that a subsequent NDP will be punctured. The receiving device may determine the feedback by measuring the portions of the NDP that are not punctured. Beamforming may be enhanced by using punctured sounding between two beamforming endpoints.

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.
