摘要： For example, a wireless communication device may be configured to disable a per-antenna Cyclic Shift Diversity (CSD) insertion for a Long Training Field (LTF) of a Physical Layer (PHY) Protocol Data Unit (PPDU), for example, based on a determination that the PPDU is to be configured for a predefined type of channel-sounding-based measurement. For example, the per-antenna CSD insertion may include insertion of a CSD between a plurality of transmit chains of the wireless communication device. For example, the wireless communication device may be configured to transmit the LTF of the PPDU via the plurality of transmit chains with the per-antenna CSD insertion disabled.

摘要： This disclosure describes systems, methods, and devices related to allocating non-continuous resource units (RUs). A device may determine a non-continuous RU allocation for one or more devices in a 80 MHz bandwidth including four 20 MHz channels, the non-continuous RU allocation including disabled tones of a 20 MHz channel of the four 20 MHz channels, and the disabled tones being a subset of tones within the 20 MHz channel. The device may determine a high efficiency wireless frame comprising an indication of the non-continuous RU allocation. The device may send the high efficiency wireless frame to one or more multiple devices.

摘要： The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.

摘要： This disclosure describes systems, methods, and devices related to passive location measurement in wireless communications. A device may perform a ranging measurement with a first device and a second device. The device may identify a first uplink (UL) location measurement report (LMR) received from the first device. The device may identify a second UL LMR received from the second device. The device may cause to send a first broadcast LMR comprising information associated with the ranging determination of the first device and the second device. The device may cause to send a second broadcast LMR comprising the measurement information carried in the first UL LMR and the second UL LMR.

摘要： Methods, apparatus, and computer-readable media are described for notching a 6 GHz channel. A station associates with an access point on a 6 GHz band. A notching pattern indication is decoded from data received from the AP after associating with the AP. A notching region within a channel within the 6 GHz band is determined based on the notching pattern indication. The notching pattern indicates a width of a notching region and a location of the notching region within the channel. The notching region covers bandwidth occupied by an incumbent system within the channel. A physical layer convergence procedure (PLCP) protocol data unit (PPDU) is encoded for transmission on the channel to the AP. The PPDU is encoded to exclude transmission within the notching region.

摘要： Disclosed are methods, devices, and computer readable storage mediums for encoding and decoding messages for fast link adaptation. In one aspect, a method of a high efficiency (HE) station (STA) (HE STA) includes encoding an aggregated control subfield of a high throughput (HT) Control field to signal one or more of: a request to use dual carrier modulation (DCM), a request to use a particular resource unit, an uplink (UL) power headroom indication, and an indication that the HE STA is using a minimum transmit power for a current modulation and coding scheme (MCS). The method also includes configuring the HE STA to transmit a HE-PPDU including the HT control field.

摘要： Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a portion of a physical layer (PHY) protocol data unit (PPDU), the first portion of the PPDU including a physical universal signal field (U-SIG), the U-SIG comprising a version independent portion and a version dependent portion, the version independent portion including a version identifier field, the version identifier field indicating a standard version of the PPDU. The processing circuitry is further configured to refrain from decoding the version dependent portion when the standard version indicates a standard version of a later generation than a standard version of the AP or STA, and otherwise decode the version dependent portion in accordance with the standard version.
