摘要： This disclosure describes systems, methods, and devices related to neighbor awareness networking (NAN) operations in the 6 GHz frequency band. A NAN device may generate a first NAN frame including a first indication of a NAN operation capability, and a second indication of a transmit power of the NAN device. The NAN device may send the first NAN frame and may identify a second NAN frame received from a second NAN device, the second NAN frame including a third indication of the NAN operation capability, and a fourth indication of a transmit power of the second NAN device. The NAN device may determine, based on the transmit power of the NAN device and the transmit power of the second NAN device, an operation parameter for the 6 GHz frequency band. The NAN device may establish, based on the operation parameter, a NAN connection using the 6 GHz frequency band.

摘要： This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.

摘要： Embodiments of a station (STA), access point (AP) and method for determination of transmit power for spatial reuse are generally described herein. The STA may detect, in the channel, an overlapping basic service set (OBSS) physical layer convergence procedure protocol data unit (PPDU) from an OBSS AP. The STA may determine, based at least partly on an ESS color parameter included in the OBSS PPDU, whether the OBSS AP is included in the ESS network. The STA may determine an OBSS power threshold based at least partly on whether the OBSS AP is included in the ESS network. The STA may determine, based at least partly on a comparison between the OBSS power threshold and a received power of the OBSS PPDU, whether to transmit an uplink PPDU to the BSS AP in the channel during the TXOP.

摘要： Methods, apparatuses, computer readable media for spatial reuse for uplink multi-user transmissions. An apparatus of a station comprising processing circuitry is disclosed. The processing circuitry may be configured to decode a first portion of a physical layer convergence procedure (PLCP) protocol data unit (PPDU), and configure the station to transmit a frame, if the PPDU is an overlapping basic service set (OBSS) PPDU, and a receive power of the PPDU is below an overlapping power detect level. An apparatus of an access point comprising processing circuitry is disclosed. The processing circuitry may be configured to encode a PPDU comprising a basic service set identifier of the access point, and encode the PPDU to indicate spatial reuse (SR) delay, SR restricted, or SR not permitted. The processing circuitry may be further configured to configure the access point to transmit the PPDU.

摘要： Computing readable media, apparatuses, and methods for random access with carrier sensing are disclosed. An apparatus is disclosed including processing circuitry configured to: decode a trigger frame, the trigger frame to indicate resource units (RUs) for random access and to indicate if a carrier sense (CS) is to be performed. The processing circuitry may be further configured to: decrement a value of an orthogonal frequency division multiple-access (OFDMA) backoff (OBO) field based on a number of the RUs indicated for random access. The processing circuitry may be further configured to: when the value of the OBO field reaches a predetermined value, randomly select one of the RUs indicated for random access, and if the CS is to be performed, determine a virtual CS based on one or more network allocation vectors (NAVs) and perform a physical CS on the selected RU, and if the virtual CS and the physical CS both indicate that the selected RU is idle, configure the wireless device to transmit a physical (PHY) layer convergence procedure (PLCP) protocol data units (PPDU) on the selected RU in accordance with OFDMA.

摘要： Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.

摘要： An apparatus for a station (STA) is generally described herein. The STA includes a low-power WUR (LP-WUR), a local timing synchronization function (TSF) timer, and processing circuitry. The processing circuitry can decode a signal received from an access point (AP) at the LP-WUR, the signal including a TSF value, the TSF value including a subset of octets of a TSF timer associated with the AP. The STA can synchronize the local TSF timer of the STA with the TSF timer associated with the AP by adjusting a local TSF timer based on a count of a number of octets included in the subset of octets. The LP-WUR can wake up a wireless local area network (WLAN) radio of the STA at a wake-up time based on the local TSF timer. Other methods, apparatuses and systems are also described.
