Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, for generating or receiving a multi-generation physical layer protocol data unit (PPDU). The multi-generation PPDU may concurrently include a first generation-specific preamble based on a first generation of a wireless communication specification (such as that defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards) and a second generation-specific preamble based on a second generation of the wireless communication specification in a same transmission. The generation-specific preambles may be generated based on bandwidth portions of a wireless channel that each generation-specific preamble will occupy in the multi-generation PPDU. One or more of the generation-specific preambles may be modified based on an aggregate bandwidth of the multi-generation PPDU. This disclosure includes several options for modifying one or more generation-specific preambles or data fields to accommodate their use in a multi-generation PPDU.

Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for generating or receiving a wireless packet that includes a first preamble based on a first generation of a wireless communication protocol and a second preamble based on a second generation of the wireless communication protocol. The wireless packet may include the first preamble in a first subchannel of a wireless channel and the second preamble in a second subchannel of the wireless channel. Thus, the wireless packet may concurrently include communication to or from different types of wireless stations that support the different generations of a wireless communication protocol.

Abstract: This disclosure provides methods, components, devices, and systems that support sounding techniques for ultra-high reliability (UHR) communications. In some implementations, a first communication device may receive a null data packet announcement (NDPA) frame associated with a UHR NDPA variant type. The NDPA frame may include sounding information for communication devices that support UHR communications. The first communication device may receive a null data packet (NDP) in accordance with the sounding information, and may perform UHR communications based on measurements of the NDP. In some other implementations, the first communication device may receive a trigger frame that indicates the NDPA, a sounding mode for transmission of the NDP, and parameters for transmission of a compressed beamforming frame (CBF) associated with the NDP. The first communication device may transmit or receive the NDP in accordance with the sounding mode, and may receive or transmit the CBF using the parameters.

Abstract: Duplicated physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmission is described for a wireless device with reduced peak-to-average power ratios (PAPR). One example includes obtaining a first sub-PPDU from ta PPDU that includes a data field with data content. A second sub-PPDU may also be obtained by duplicating the PPDU including the data content of the PPDU. At least one of a phase rotation, a phase offset, or a phase ramp is applied to at least a portion of a second set of sub-carrier of a wideband channel. The first sub-PPDU is transmitted on a first set of sub-carriers of the wideband channel and the second sub-PPDU is transmitted on the second set of sub-carriers of the wideband channel.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may transmit control signaling to a second device. The control signaling may indicate a set of different modulation and coding schemes (MCSs) to be applied to at least one of a set of spatial streams or a set of resource units (RUS), where the control signaling may indicate that a respective MCS to be applied to a respective spatial stream or to a respective RU. The first device may transmit, one or more first bits of a first service data unit to the second device via a first spatial stream of or via a first RU using a first MCS and transmit one or more second bits, of the first service data unit or of a second service data unit via a second spatial stream or via a second RU using a second MCS.

Abstract: This disclosure provides methods, components, devices and systems for extended long range wireless packet design. Some aspects more specifically relate to increasing a data rate, a coverage range, or both for extended long range (ELR) wireless communications systems by updating an ELR wireless packet design. A wireless communications device, such as a wireless station (STA), may transmit an ELR wireless packet to another wireless communications device, such as a wireless access point (AP), with updated preamble fields, boosted transmit power for one or more preamble fields, and/or additional repetitions for one or more preamble fields. Additionally, or alternatively, the wireless communications device may transmit an ELR wireless packet using a narrow bandwidth to increase coverage range for an ELR wireless communications system.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to pilot tone designs that support distributed transmission. A transmitting device may modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical RU associated with the legacy tone plan and may further map the M tones to M noncontiguous subcarrier indices associated with a wireless channel. The transmitting device may transmit the PPDU, over the wireless channel, with a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices. In some implementations, the relative locations of the N pilot tones may be different than relative locations of a number (K) of pilot tones associated with the logical RU.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.

Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for including signaling regarding enhanced features of new wireless communication protocols. The signaling may be included in various portions of a physical layer preamble of a wireless transmission. In some implementations, the physical layer preamble may be used to indicate puncturing of subbands or content channels that may carry further signaling in accordance with preamble signaling designs of this disclosure. The physical layer preamble signaling be parallelized for different subchannels of a wireless channel that consists of multiple subchannels. Some implementations of the physical layer preambles may be used to multiplex different types of wireless local area network communications into different subsets of the plurality of subchannels of the wireless channel.
