Abstract: Generally, the described techniques provide for protection mechanisms for sounding training signals transmitted between wireless devices when performing ranging sounding estimation. For example, sounding training signals may be encoded to include a sequence of phase rotations or cyclic shifts to protect the sounding training signal from peer devices. In some cases, encoding information associated with a long training field (LTF) may be transmitted either before or after the LTF is transmitted. Additionally or alternatively, a time delay may be introduced to the sounding training signal, where timing information may be removed from one or more fields of the sounding training signal and the time delay may be appended to an interframe spacing. Alternatively, a frame may be split into multiple frames with the sounding training signal in a first frame, and timing information in a second frame that is offset in time from the first frame.

Abstract: Methods, systems, and devices for wireless communications are described, including identifying a first attribute value associated with a first access point; receiving a second attribute value; and determining that the first attribute value associated with the first access point is the same as the received second attribute value. An attribute value may be an n-bit value, where n is an integer. The n-bit value may identify a BSS color. The n-bit value may, additionally or alternatively, indicate other BSS color information such as a BSSID, ESSID, SSID, or a combination thereof. It is helpful when devices detect BSS attribute value (e.g., BSS color, BSSID, MAC address, ESSID) overlap and notify other associated devices (e.g., STAs, APs) of this overlap so that a device may cease using an attribute value for power save or channel access decisions, and facilitate attribute value adjustment and correction to eliminate a BSS collision.

Abstract: This disclosure provides methods, components, devices, and systems for acknowledgment (ACK) processing associated with medium access control (MAC) header verification, payload verification, or both. Some aspects more specifically relate to a first wireless device advertising a processing capability associated with performing MAC protocol data unit (MPDU) verification, including MAC header verification, payload verification, or both. In some implementations, the processing capability may include a processing latency to perform the verification, a threshold quantity of MPDUs supported for the verification within a short interframe spacing (SIFS) time interval, or both. The first wireless device may transmit an indication of the processing capability to a second wireless device. In some implementations, the second wireless device may transmit MPDUs to the first wireless device in accordance with the processing capability. Additionally, or alternatively, the first wireless device may transmit an ACK frame for the MPDUs in accordance with the processing capability.

Abstract: This disclosure provides methods, components, devices, and systems for signaling for dynamic subchannel operation (DSO). Some aspects more specifically relate to indicating a set of subchannels supported for DSO. In some implementations, a wireless station (STA) may transmit a frame indicating subchannels supported for DSO (for example, for a specific link). An access point (AP) may receive the frame and may assign, using a control frame, one or more frequency resources of a subchannel of the set of subchannels to the STA for DSO. The STA may dynamically switch to the subchannel and may communicate via the subchannel while operating in a DSO mode. In some implementations, the STA may transmit capabilities information indicating that the STA supports the DSO mode. Additionally, or alternatively, the STA may dynamically enable or disable the DSO mode using action frames or aggregated-control (A-Control) subfields. The AP may support similar signaling.

Abstract: Disclosed embodiments facilitate efficient positioning of stations (STAs) one wireless networks. A method on an Access Point may determine, at a first time, availability of the Access Point (AP) for positioning; and transmit, based at least in part, on the determination, information indicative of the AP's availability for positioning. The transmitted information may comprise one or more of: STA-AP location determination availability, STA-AP location determination capability, whether AP-AP positioning is being performed; and/or the next scheduled AP-AP ranging session. In some embodiments, a STA may initiate location determination to determine a location of the STA based, at least in part, on indications of availability for positioning for one or more Access Points (APs) communicatively coupled to the STA. Each indication of availability may correspond to a distinct AP of the one or more APs, and the location determination may comprise either: STA-AP location determination, or passive location determination.

Abstract: Aspects of the present disclosure allow for one or more network allocation vectors (NAVs) to control whether or not the STA may transmit on the wireless channel depending on whether the NAV was set by a device in the same BSS (“intra-BSS”) or from a different BSS (OBSS or “inter-BSS”). In one aspect, the STA may maintain two NAVs (intra-BSS NAV and inter-BSS NAV). In accordance with one technique, if the inter-BSS NAV was previously set based on an in-deterministic frame (e.g., a frame received by the STA that cannot readily be identified as either intra-BSS frame or an inter-BSS frame), then the STA may respond to a trigger frame from an AP after the inter-BSS NAV has been set as though the inter-BSS NAV is intra-BSS NAV.
