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: A method performed by an electronic device is described. The method includes receiving a long training field (LTF) in a preamble of a packet. A power of the LTF is boosted relative to a power of a data field of the packet. The method also includes receiving a power amplifier (PA) model or a PA distortion error from a transmitting device. The method further includes regenerating a post-PA transmitted LTF based on the PA model or the PA distortion error. The method additionally includes demodulating the data field based on an estimated channel with deboosting.

Abstract: Methods and apparatuses for providing wireless messages can include, for example, an apparatus configured to provide wireless communication. The apparatus includes a memory that stores instructions and a processor coupled with the memory and configured to execute the instructions to select a dual sub-carrier modulation (DCM) mode or a non-DCM mode. The processor is further configured to select one or more interleaver parameters based on the selection of the DCM mode or the non-DCM mode. The processor is further configured to select a first set of interleaver parameters when the DCM mode is selected and a second set of interleaver parameters, different than the first set of interleaver parameters, when the non-DCM mode is selected. The processor is further configured to apply the one or more interleaver parameters to interleave data of a message. The processor is further configured to provide the message for transmission to a receiving device.
