Abstract: Certain embodiments herein relate to efficient location determination by wireless stations using one-to-many communication techniques. Location determination can be facilitated by using one-to-many communication techniques to provide for efficient timing message exchange between an initiating wireless station and one or more responding wireless stations. Based at least in part on the time-of-flight of the exchanged messages, the initiating wireless station can determine its distances from the respective one or more responding wireless stations. Based at least in part on the determined distances, the wireless initiating station can determine its location using trilateration or multilateration techniques.

Abstract: Embodiments of a communication station and method for time-of-flight (ToF) location determination in a wireless network are generally described herein. In some embodiments, a responding communication station receives a ToF measurement request. The responding communication station transmits an acknowledgment of the ToF measurement request. The responding communication station also transmits a response to the ToF measurement request that includes an indication of a time period for an initiating communication station to poll the responding communication station for a ToF result.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of performing a range measurement. For example, a first wireless communication device may include a radio to communicate a discovery frame with a second wireless communication device, the discovery frame including at least one movement indication field to indicate a time of movement of a sender of said discovery frame; and a controller to perform a range measurement procedure with said second wireless communication device.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of determining a Time Synchronization Function (TSF) based on Fine Timing Measurement (FTM) messages. For example, a wireless station may be configured to determine a first TSF value of a local TSF of the wireless station at arrival of a first FTM message from a responder station; to determine a second TSF value of the local TSF at arrival of a second FTM message from the responder station, the second FTM message including a first Time of Departure (TOD) value of the first FTM message; to process a third FTM message from the responder station, the third FTM message including a second TOD value of the second FTM message; and to apply to the local TSF a TSF correction based at least on the first TSF value, the second TSF value, the first TOD value, and the second TOD.

Abstract: An access point (AP), station (STA) and method of providing synchronizing the STA are generally described. The STA may transmit to the AP a Fine Timing Measurement (FTM) request and/or trigger frame. The STA may capture a STA Time Synchronization Function (TSF) value of the time the FTM request/trigger frame is transmitted to the AP as determined by the STA. The AP may determine an AP TSF value of the time the of the FTM request/trigger frame was transmitted by the AP as determined by the AP and transmit at least part of the AP TSF time to the STA in a FTM response frame. The STA may compare the STA TSF value and the AP STA value and adjust the STA TSF dependent on the difference between the AP TSF value and the STA TSF value to synchronize to the AP TSF value.

Abstract: Embodiments allow a station to determine its location and report the location to a access point or other network entity. The station obtains agreement with an access point, group of access points, or other network entity to provide its location to a designated accuracy level and the access point(s) agree to provide services such as access to a location service, the access point(s) location to a designated positional accuracy, etc. The station measures its position and induces an error in its reported location. The induced error prevents an exact location of the station from being determined by the access point(s) or others, thus preserving the privacy of the station. The location reported by the station may be absolute (e.g., geographic coordinates) or relative to a landmark, location, etc.

Abstract: Embodiments of a communication station (STA) and method for time-of-flight (ToF) positioning in a wireless network are generally described herein. In some embodiments, an initiating station may transmit a message M1 carrying a high-throughput control (HTC) field that includes a reverse direction grant (RDG) bit. The RDG indication grants permission to a responding station to send information back to the initiating station. The message M1 may be a timing measurement action frame. An ACK frame may be received from Me responding station to acknowledge receipt of the message M1. The ACK frame may optionally carry an HTC field that includes amore PPDU indication to indicate whether a PPDU (e.g., contained in message M2) is to follow the ACK frame. The message M2 may be received from the responding station and may include timing measurement information from a current and/or one or more previous ToF message exchanges.

Abstract: Fine Timing Measurement (FTM) Burst Management during Time-of-Flight (ToF) measurements in a wireless network separates FTM traffic from other traffic activity using two distinct Media Access Control (MAC) addresses and by coordinating access availability durations between FTM activity and other traffic. Communication stations save power by powering down receive paths between FTM frames. A communication station arranged for FTM Burst Management comprises physical layer circuitry and processors to use a first MAC address for FTM procedure signals, and a second MAC address that is distinct from the first MAC address for data and traffic signals other than FTM procedure signals, and exchange FTM procedure signals with the Access Point (AP) during scheduled FTM burst access availability periods using the first MAC address, and exchange other data and traffic signals with the AP during other access availability periods using the second MAC address.
