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, 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: 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 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.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for link adaptation in a wireless local area network (WLAN). A link adaptation test packet from a first WLAN device to a second WLAN may include a plurality of link adaptation test portions that are generated using a corresponding plurality of transmission rate options. For example, the plurality of link adaptation test portions may be modulated using different modulation and coding scheme (MCS) options. Thus, a single test packet may be used to evaluate different transmission rate options. The second WLAN device may provide feedback information regarding the link adaptation test portions. The feedback information may be used to determine a transmission rate for a subsequent transmission from the first WLAN device to the second WLAN device based on wireless channel conditions.

Abstract: This disclosure provides methods, devices and systems for interpreting reserved bits and values associated with different releases of a wireless communication protocol. In some implementations, a wireless communication device may determine whether to terminate or continue reception of a physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) if it detects a reserved bit in the physical layer preamble set to an unsupported value (such as a value different than what is defined by a version or release of the wireless communication protocol supported by the wireless communication device). In some other implementations, a wireless communication device may determine whether to terminate or continue reception of a PPDU if it detects a field in the physical layer preamble set to a reserved value (such as defined by a version or release of the wireless communication protocol supported by the wireless communication device).

Abstract: This disclosure provides methods, devices and systems for generating enhanced sounding packets. Some implementations more specifically relate to sounding packet designs that support enhancements to wireless communication protocols associated with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced null data packet announcement (NDPA) frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, the enhanced NDPA frame may be configured in accordance with a legacy or a non-legacy NDPA frame format. In some other implementations, the enhanced NDPA frame may include a subfield carrying information identifying a particular basic service set (BSS) which may be associated with one or more STA information fields. Still further, in some implementations, an Extremely High Throughput (EHT) PPDU may include signaling to indicate whether the EHT PPDU is formatted as a sounding NDP.

Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame 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. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.
