Abstract: This disclosure describes systems, methods, and devices related to secure location measurement sharing. A device may cause to send a first indication associated with a location of the device to a cloud server. The device may cause to send a second indication associated with a ranging information of an access point (AP), wherein the AP is connected to the cloud server. The device may identify an access token received from the cloud server, wherein the access token is associated with providing anonymized AP location information to the AP, and wherein the access token is associated with accessing channel allocation from a channel access database.

Abstract: Methods, apparatuses, and computer readable media for channel state information for multiple access points are disclosed. Channel station information (CSI) may be coordinated for multiple access points (APs) where one AP may act as a master AP with other AP acting as slave APs. The channel station information may be based on information from null data packets received by stations from multiple-APs, which may enable a multi-AP coordinated beamforming (CBF) to be determined based on the received first CSI reports. New frame formats are disclosed that include fields for including APs. Overlapping basic service set (OBSS) stations may respond to APs that are not within their BSS. Some embodiments relate to passive range finding in a multi-AP sounding where location configuration information (LCI) changes for one of the APs.

Abstract: This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.

Abstract: This disclosure describes systems, methods, and devices related to null data packet (NDP) frame format. A device may cause to send a null data packet announcement (NDPA) frame to a responding station device (RSTA). The device may cause to send a first sounding NDP frame comprising one or more fields formatted to support 2.4 gigahertz (GHz) and 5 GHz bands in a non-trigger-based ranging measurement with the RSTA. The device may identify after a passage of a short inter-frame space (SIFS) time a second NDP frame received from the RSTA. The device may identify a location measurement report frame from the RSTA.

Abstract: This disclosure describes systems, methods, and devices related to uplink (UL) null data packet (NDP) format for passive location. A device may cause to send a trigger frame that solicits poll response to one or more anchor stations involved in a passive ranging measurement. The device may identify one or more polling response frames received from the one or more anchor stations. The device may cause to send a trigger frame that solicits uplink null data packet (NDP) to the one or more anchor stations, wherein the uplink NDP comprises an indication of a high efficiency (HE) single user (SU) frame type. The device may identify one or more uplink NDPs received from the one or more anchor stations

Abstract: Some demonstrative embodiments include apparatuses systems and/or methods of ranging measurement. For example, an apparatus may include circuitry and logic configured to cause a first wireless communication station (STA) to receive from a second STA a sounding transmission for a range measurement of a range between the first STA and the second STA; to determine a channel response estimation based on the sounding transmission from the second STA; to determine a timing value based on the channel response estimation; and to transmit a feedback message to the second STA, the feedback message including the timing value.

Abstract: Generally discussed herein are systems and apparatuses arranged to perform a Time-of-Flight (ToF) or Round Trip Time measurement. The disclosure also includes techniques of making and using the systems and apparatuses. According to an example a station (STA) can be arranged to perform a Time-of-Flight (ToF) measurement, the STA can include a transceiver arranged to transmit a hard constraint indicating a time window in which the STA is unavailable for performing the ToF measurement, and receive an action frame of the ToF measurement from another STA at a time that is outside the time window.
