Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A packet is decoded and demodulated by an M2M device that is received during a time slot of a physical layer forward link frame in the M2M wireless WAN. The packet is transmitted by a base station. The M2M device enters a sleep state before a physical layer acknowledgment (ACK) message is transmitted to the base station to indicate receipt of the packet.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for priority access on a shared wireless channel. A priority station (STA), an access point (AP), or a network operator may activate a priority access service. The priority access service provides priority access to authorize priority STAs by allowing them to use more aggressive contention parameters for contention-based access of the wireless channel as compared to other STAs. In some implementations, non-priority STAs may be configured with weakened contention parameters to increase or ensure the likelihood that a priority STA will win contention for access to the wireless channel.

Abstract: This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks (WLANs). Some implementations more specifically relate to packet designs and numerologies that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a wireless communication device may up-clock a physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) for transmission on carrier frequencies above 7 GHz, where the PPDU conforms to an existing PPDU format associated with carrier frequencies below 7 GHz. As used herein, the term “up-clocking” refers to increasing the frequency of a clock signal used to convert the PPDU between the frequency domain and the time domain. In some aspects, the up-clocking may result in a subcarrier spacing (SCS) greater than or equal to 1.2 MHz, where the SCS represents a spacing between the subcarriers on which a PHY preamble of the PPDU is modulated.

Abstract: This disclosure provides methods, devices and systems for generating packet preambles. Some implementations more specifically relate to preamble designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. Among other examples, the preamble designs of the present implementations may allow for more reliable packet detection, more accurate channel estimation, and more robust decoding of signal field (SIG) symbols. Additionally, or alternatively, the preamble designs of the present disclosure may be implemented with different lengths, modulation schemes, or transmit power compared to preamble designs that conform to existing versions of the IEEE 802.11 standard.

Abstract: This disclosure provides wireless communication methods, components, devices and systems for applying spectral masks and spectral flatness parameters in conjunction with transmission of millimeter wave (mmWave) signals in wireless communication networks. In some examples, in conjunction with transmission of an mmWave signal, a wireless communication device can apply a derivative spectral mask featuring transitional offset ranges that correspond to transitional frequency offset ranges of a spectral mask for a nominal carrier signal, scaled according to a ratio between a bandwidth of the mmWave signal and a bandwidth of the nominal carrier signal. In some examples, the derivative spectral mask can feature an in-band frequency offset range that is wider than a scaled width of an in-band frequency offset range of the spectral mask for the nominal carrier signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an initiating device may transmit a signal that includes multiple packets. The initiating device may receive, from a responding device, a channel impulse response (CIR) report for each packet of the multiple packets. The initiating device may align, using one or more taps in the CIR report for each packet, the CIR reports across the multiple packets to identify a target object, a location of the target object, or a movement of the target object. The initiating device may perform an action based at least in part on the target object, the location of the target object, or the movement of the target object. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices and systems for radio frequency sensing control for an ultra-wideband system. Some aspects more specifically relate to setting up one or more sensing instances (sensing rounds) for one or more respective sensing operations. In some implementations, a first wireless device (for example a controller, an initiator) may transmit a sensing session setup request frame that indicates a set of parameters for the one or more sensing instances. For each of the sensing instances, the first wireless device may transmit a sensing control information element that includes at least a common sensing control configuration and a channel impulse response report configuration. The first wireless device may participate in the sensing operations with at least a second wireless device (for example one or more responders or controlees) during the respective sensing instances.

Abstract: This disclosure provides methods, devices and systems that support communicating using orthogonal frequency division multiple access (OFDMA) according to a tone plan that supports 20 MHz subchannel puncturing within a wireless channel. In some aspects, a non-legacy tone plan may define a set of tones for a resource unit (RU) such that the RU does not overlap a 20 MHz subchannel boundary of the wireless channel. The locations of the set of tones in the non-legacy tone plan may be shifted relative to corresponding tones associated with a corresponding RU according to a legacy tone plan. One or more of the disclosed tone plans may enable puncturing of subchannels while making use of some RUs that would otherwise partially overlap a punctured subchannel in the legacy tone plan.

Abstract: This disclosure provides methods, devices and systems for distributed transmission of short training fields in a power spectral density limited frequency band. In one aspect, a device receives a distributed resource unit (dRU) assignment for transmission of a dRU portion of a physical layer protocol data unit (PPDU); determines a spatial stream global cyclic shift delay (CSD) index for an short training field (STF) of the dRU portion of the PPDU; and transmits, based on the spatial stream global CSD index, the EHT of the dRU portion of the PPDU across a dRU spreading bandwidth associated with the dRU assignment using a tone plan and sequence corresponding to a regular resource unit (rRU) transmission mode.
