Abstract: For example, a wireless communication device may be configured to generate a wide bandwidth Long Training Field (LTF) configured for channel sounding over a wide channel bandwidth of at least 320 Megahertz (MHz). For example, the wide bandwidth LTF may include a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols over the wide channel bandwidth. For example, the wireless communication device may be configured to transmit a Null Data Packet (NDP) over the wide channel bandwidth. For example, the NDP may include a non-High-Throughput (non-HT) Short Training Field (L-STF), a non-HIT LTF (L-LTF) after the L-STF, a non-HT Signal (L-SIG) field after the L-LTF, a Repeated L-SIG (RL-SIG) field after the L-SIG field, and the wide bandwidth LTF after the RL-SIG field.

Abstract: This disclosure describes systems, methods, and devices related to extremely high throughput (EHT) trigger based (TB) preamble. A device may receive a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device. The device may generate an EHT physical layer protocol data unit (PPDU) based on receiving the trigger frame from the access point, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field. The device may encode the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs. The device may cause to send the PPDU to the AP and an uplink data transmission direction.
