Abstract: A technique for wireless communication of a punctured null data packet with a long training field sequence is disclosed. The long training field (LTF) sequence is generated for the null data packet (NDP) for transmission over a channel having a bandwidth that is an integer multiple of 80 MHz. The LTF sequence is modulated onto a plurality of tones of the channel excluding tones within a punctured subchannel of a plurality of subchannels of the channel. The modulation may be based on a size and location of the punctured subchannel and a symbol duration associated with transmitting the LTF sequence. The NDP is transmitted including the LTF sequence to a second wireless communication device via the channel. A partial bandwidth feedback may be received in response to the LTF in the punctured NDP.

Abstract: Various aspects relate generally to the generation and wireless transmission of a long training field (LTF) and a data field within a 320 MHz or 240 MHz bandwidth channel. The LTF includes an LTF sequence based on a concatenation of a plurality of LTF subsequences, each LTF subsequence being associated with a channel bandwidth less than the total bandwidth of the channel, each of the plurality of LTF subsequences being selectively phase-rotated to reduce a peak-to-average power ratio. Each of the plurality of LTF subsequences may be associated with an LTF designed for an 80 MHz bandwidth channel. The LTF and the data field may then be transmitted in a wireless packet to at least one second wireless communication device via the 320 MHz or 240 MHz bandwidth channel.

Abstract: This disclosure provides methods, devices, and systems for a wireless communication device to perform signal phase rotation. In some implementations, the wireless communication device may determine a number of phase rotation parameters to be applied to a number of tones of a transmission signal. In some aspects, each of the phase rotation parameters indicates a phase rotation to be applied to each of the tones according to a carrier index range for each of the tones and a bandwidth mode for the transmission signal. In some implementations, the wireless communication device may apply the phase rotation parameters to respective ones of the tones according to the specified phase rotations and the carrier index ranges, and transmit the transmission signal from the wireless communication device according to the applied phase rotation parameters.

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.
