    摘要: A next generation vehicle-to-everything (NGV) station (STA) operating as an initiating station (ISTA) for performing non-trigger-based NGV ranging may encode an NGV ranging null-data packet (NDP) announcement (NGV NDPA) frame for transmission to a responding station (RSTA) to initiate the non-trigger-based NGV ranging. The NGV STA may also encode an initiator-to-responder (I2R) NGV ranging null-data packet (NDP) (I2R NGV ranging NDP) for transmission following the NGV NDPA frame. The I2R NGV ranging NDP may be encoded in accordance with a NGV Ranging NDP format that may include an NGV signal field (NGV-SIG), a repeated NGV-SIG (RNGV-SIG), an NGV Short Training field (NGV-STF) and an NGV long training field (NGV-LTF). The NGV-LTF may include one or two sets of LTF symbols depending on a number of LTF symbol repetitions (LTF_REP). Each set of LTF symbols may have one or two LTF symbols depending on a number of spatial streams (NUM_SS) and the NGV-LTF may be encoded without a packet extension (PE).

    摘要: This disclosure describes systems, methods, and devices related to physical layer (PHY) signaling in next generation vehicle (NGV). A device may establish a communication session with one or more NGV devices. The device may determine an NGV frame comprising a legacy signal field (L-SIG) and an NGV signal field. The device may determine a plurality of data subcarriers and a plurality of pilot subcarriers associated with the L-SIG, wherein the plurality of data subcarriers and the plurality of pilot subcarriers are surrounded by at least two additional subcarriers. The device may cause to send the NGV frame to the one or more NGV devices.
