This application claims the benefit of U.S. Provisional Application No. 62/449,906, filed Jan. 24, 2017, the disclosure of which is incorporated herein by reference as if set forth in full.
This disclosure generally relates to systems and methods for wireless communications and, more particularly, to enhanced location service negotiation among wireless devices.
Wireless devices are becoming widely prevalent, making them suited for location-based services (e.g., location determinations). Wireless devices may benefit from location-based services that may result in an enhanced user experience. Recently, there has been a shift in technology to support location services between a wireless device and multiple access points.

Example embodiments described herein provide certain systems, methods, and devices for location determination, including, but not limited to, the IEEE 802.11 family of standards.
A Wi-Fi device may perform a timing measurement procedure, known as fine timing measurement (FTM), in order to allow the Wi-Fi device to obtain its range to another device, such as an access point (AP), a station (STA), or an FTM responder. Generally, the range of the Wi-Fi device to the another device is a distance between the two devices. The Wi-Fi devices can determine its distance (from the another device) by measuring a time it takes for, e.g., a packet or frame to travel from one device to another. The FTM procedure is an IEEE 802.11 protocol introduced to support location determination by a device based on range measurements to multiple known responding devices that can be associated or unassociated with the device. The device can execute, with the multiple known responding devices, location determination techniques, including triangulation, trilateration, etc.
Current location protocols consider multiple APs when (a) providing information as part of a neighbor report (a frame of an access network query protocol (ANQP)) to provide a STA with information of surrounding APs or (b) requesting range measurement to a specific set of APs. However, to conduct range measurements to APs specified in a neighbor report, the STA still needs to separately negotiate an FTM procedure with each AP in the APs during a negotiation phase. Conventionally, the negotiation phase comprises the STA performing an FTM negotiation with each AP in the APs to determine an identification (e.g., unique IDs (UIDs), associated IDs (AIDs), ranging AIDs (R-AIDs), etc.) that the STA can use during a subsequent measurement phase with the APs. In other words, a conventional FTM procedure is mostly used as a single input single output protocol. Separately negotiating the FTM procedure with each AP in the APs creates both delay and medium overhead as a new measurement capabilities exchange and resource allocation need to be established (between the STA and each AP).
Example embodiments of the present disclosure relate to systems, methods, and devices for enhanced location service negotiation.
In one embodiment, an enhanced location service negotiation system may define an enhanced FTM protocol for location measurement (e.g., FTM measurement, position service, etc.) between a group of coordinated APs and one STA. The group of coordinated APs can comprise APs that are in communication with each other (e.g., by a controller, over a communication protocol, etc.), to provide WLAN services to STAs that are associated with only one AP in the group of APs. STA may be either associated with only one of the APs of the group or unassociated to all the APs. Alternatively, the STA may be associated with some of the APs (but not all).
In one embodiment, an enhanced location service negotiation system comprises a group of coordinated APs that are each capable of transmitting, to the STA, an extended neighbor report (e.g., as a frame) that comprises location capability support information. The location capability support information comprises identification information that the STA uses when performing the FTM measurement to the group of coordinated APs. The location capability support information can be used by the STA to facilitate a negotiation phase of an enhanced location service negotiation system. Particularly, the STA can identify an extended neighbor report that is transmitted by an AP in the group of coordinated APs; determine identification information for the STA; and perform location measurements with the group of coordinated APs using the determined identification.
With particularity regarding the location capability support information of the extended neighbor report, the location capability support information facilitates FTM negotiation between the STA and each AP in the group of coordinated APs, not only a single AP (in the group of coordinated APs) that is serving the STA. The location capability support information can be a modified portion (or an additional portion) of a conventional neighbor report (e.g., the Neighbor Report defined in IEEE 802.11k) that comprises information indicating capabilities of each AP in the group of coordinated APs. The location capability support information can comprise a R-AID that can be assigned to the STA and valid, when the STA performs FTM measurement, for each AP in the group of coordinated APs. The R-AID can be assigned so that it is unique to the STA and may not correspond to an associated ID (AID) of another STA associated to another AP of the group of coordinated APs or to another unassociated STA within the group. This may require coordination among the group of coordinated APs.
A keep-alive timeout may define a time period after which the R-AID (assigned to the STA) is no longer valid, unless the STA and an AP in the group of coordinated APs performs a successful frame exchange, in which case the keep-alive timeout is reset to an original value. An AP in the group of coordinated APs may define the original value during the negotiation phase. The original value, alternatively, can be advertised in beacons and probe responses.
In one embodiment, the R-AID may be, alternatively, only valid per the AP (that transmits the extended neighbor report) for the STA, but multiple R-AIDs may be temporarily assigned to the STA with the extended neighbor report. The extended neighbor report can comprise information regarding neighbor APs (in the group of coordinated APs) with which location measurements are possible for the STA. To this end, the location capability support information can comprise, for each AP of the neighbor APs, additional R-AIDs that the STA may use to perform location measurement with the each AP of the neighbor APs. The location capability support information can also comprise one or more keep-alive timeouts for the additional R-AIDs when the extended neighbor report is unicasted to the STA. If the neighbor report is broadcasted by an AP in the group of coordinated APs, the broadcasting AP can include, in the location capability support information of the extended neighbor report, a range of R-AIDs that the STA can use if the STA is to perform location measurement (with each AP in the group of coordinated APs).
In one embodiment, the location capability support information can, for each AP in the group of coordinated APs, additionally comprise: (1) a type of location services available at neighbor APs (e.g., Single-User (SU)/Multi-User (MU) High Efficiency (HE) range, angular, scalable mode); (2) a time difference in a traffic filtering service (TFS) between a reporting AP and a neighbor AP; (3) a target beacon transmission time (TBTT) that is a time at which an AP should send its beacons; (4) a target time of service periods for location service for a negotiation phase or a measurement phase (e.g., a target wait time (TWT) between measurement resource requests opportunities at a neighbor AP); and (5) capabilities for location service. Based on the aforementioned location capability support information, the STA may improve its scanning and AP selection for concurrent operation of location measurements and data transmissions.
In one embodiment, once a negotiation phase of an enhanced location service negotiation system is established (e.g., a STA has determined its R-AID), the STA may then choose one or more possible opportunities for a measurement phase using a trigger frame (TF) short feedback, which may meet positioning requirements and scheduling constraints of a group of coordinated APs. If a location measurement is not requested by the STA using the R-AID in an FTM Resource Request mechanism (e.g., using a Null Data Packet (NDP) Short Feedback for FTM measurement), then the aforementioned R-AID is released and a new negotiation phase of the enhanced location service negotiation system is established.
The above descriptions are for purposes of illustration and are not meant to be limiting. Numerous other examples, configurations, processes, etc., may exist, some of which are described in greater detail below. Example embodiments will now be described with reference to the accompanying figures.

The one or more communications antennas may be any suitable type of antennas corresponding to the communications protocols used by the user device(s) 120 (e.g., user devices 122, 124, 126) and the AP 102. Some non-limiting examples of suitable communications antennas include Wi-Fi antennas, Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards compatible antennas, directional antennas, non-directional antennas, dipole antennas, folded dipole antennas, patch antennas, multiple-input multiple-output (MIMO) antennas, omnidirectional antennas, quasi-omnidirectional antennas, or the like. The one or more communications antennas may be communicatively coupled to a radio component to transmit and/or receive signals, such as communications signals to and/or from the user devices 120 and/or AP 102.
Any of the user device(s) 120 (e.g., user devices 122, 124, 126) and AP 102 may be configured to perform directional transmission and/or directional reception in conjunction with wirelessly communicating in a wireless network. Any of the user device(s) 120 (e.g., user devices 122, 124, 126), and AP 102 may be configured to perform such directional transmission and/or reception using a set of multiple antenna arrays (e.g., DMG antenna arrays or the like). Each of the multiple antenna arrays may be used for transmission and/or reception in a particular respective direction or range of directions. Any of the user device(s) 120 (e.g., user devices 122, 124, 126), and AP 102 may be configured to perform any given directional transmission towards one or more defined transmit sectors. Any of the user device(s) 120 (e.g., user devices 122, 124, 126), and AP 102 may be configured to perform any given directional reception from one or more defined receive sectors.
MIMO beamforming in a wireless network may be accomplished using RF beamforming and/or digital beamforming. In some embodiments, in performing a given MIMO transmission, user devices 120 and/or AP 102 may be configured to use all or a subset of its one or more communications antennas to perform MIMO beamforming.
Any of the user devices 120 (e.g., user devices 122, 124, 126) and AP 102 may include any suitable radio and/or transceiver for transmitting and/or receiving radio frequency (RF) signals in the bandwidth and/or channels corresponding to the communications protocols utilized by any of the user device(s) 120 and AP 102 to communicate with each other.

The radio components may further have hardware and/or software instructions to communicate via one or more Wi-Fi and/or Wi-Fi direct protocols, as standardized by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards. In certain example embodiments, the radio component, in cooperation with the communications antennas, may be configured to communicate via 2.4 GHz channels (e.g. 802.11b, 802.11g, 802.11n, 802.11ax), 5 GHz channels (e.g. 802.11n, 802.11ac, 802.11ax), or 60 GHZ channels (e.g. 802.11ad). In some embodiments, non-Wi-Fi protocols may be used for communications between devices, such as Bluetooth, dedicated short-range communication (DSRC), Ultra-High Frequency (UHF) (e.g. IEEE 802.11af, IEEE 802.22), white band frequency (e.g., white spaces), or other packetized radio communications. The radio component may include any known receiver and baseband suitable for communicating via the communications protocols. The radio component may further include a low noise amplifier (LNA), additional signal amplifiers, an analog-to-digital (A/D) converter, one or more buffers, and digital baseband.
When an AP (e.g., AP 102) establishes communication with one or more user devices 120 (e.g., user devices 122, 124, and/or 126), the AP 102 may communicate in a downlink direction and the user devices 120 may communicate with the AP 102 in an uplink direction by sending data frames in either direction. The user devices 120 may also communicate peer-to-peer or directly with each other with or without the AP 102.
In one embodiment, and with reference to FIG. 1, a user device 120 may perform location negotiation 140 with one or more AP(s) 102. User device 120 may be considered as an initiating device, also referred to as a station device (STA), and at least one of the AP 102 may be considered as a responding device.
With reference to FIG. 1, one or more user devices 120 may desire to obtain its range from another device (e.g., the one or more APs 102). In one embodiment, the one or more APs 102 can comprise a first coordinated AP 104, a second coordinated AP 106, and a third coordinated AP 108 that allow the one or more user devices 120 to use enhanced location service negotiation. The first coordinated AP 104, the second coordinated AP 106, and the third coordinated AP 108 can be coordinated, e.g., in a proprietary manner, by a controller-based method, or by an over the air method, etc., to provide services (e.g., location determination) to the one or more user devices 120. Further, the one or more user devices 120 can perform a location determination when (a) it is associated with only one coordinated AP (e.g., the first coordinated AP 104, the second coordinated AP 106, or the third coordinated AP 108) or (b) unassociated with all the coordinated APs in one or more APs 102.
In one embodiment, there may be two phases associated with the one or more devices 120 performing the location determination with the one or more APs 102: a negotiation phase and a measurement phase. The negotiation phase can be when the one or more user devices 120 and the one or more APs may exchange capabilities and negotiate type(s) of measurements to be determined. An enhanced location service negotiation system may use a location negotiation frame 140 to facilitate the negotiation phase. This phase may be done only once. Subsequent to the (first) negotiation phase, the measurement phase can be when the one or more user devices 120 and the one or more APs 102 may perform measurements (e.g., by performing FTM procedures). The enhanced location service negotiation system may use an exchange of at least one location measurement frame 150 to facilitate the measurement phase. These measurements may be done multiple times.
In one embodiment, an enhanced location service negotiation system allows the one or more user devices 120 to perform the negotiation phase with each coordinated AP in the one or more APs 102 using the location negotiation frame 140. The location negotiation frame 140 can be unicasted or broadcasted by each of the one or more APs 102. In the enhanced location service negotiation system, the location negotiation frame 140 can comprise a neighbor report frame that comprises location capability support information. The location capability support information comprises identification information that the one or more user devices 120 uses when performing the FTM measurement to the one or more APs 102. The location capability support information facilitates the negotiation phase between the one or more devices 120 and each coordinated AP in the one or more APs, not just an individual coordinated AP.
In one embodiment, the location capability support information can be a modified portion (or an additional portion) of a conventional neighbor report (e.g., the Neighbor Report defined in IEEE 802.11k) that comprises information indicating capabilities of the one or more APs 102. Conventionally, a neighbor report comprises (1) the basic service set identifiers (BSSIDs) of APs from a group of APs that support location services; and (2) for each AP in the group of APs, a channel on which the each AP operates. In the enhanced location service negotiation system, the location capability support information (of an extended neighbor report) can further comprise an R-AID that can be (a) assigned to a user device (e.g., user devices 122, 124, and/or 126) of the one or user devices 112 and (b) valid, when the user device (122, 124, or 136) performs FTM measurements with each coordinated AP in the one or more APs 102. The R-AID can be assigned so that it is unique to a user device (e.g., user devices 122, 124, and/or 126) and may not correspond to an AID of another user device (that is associated to a coordinated AP of the one or more APs 102) or to another unassociated user device. In such embodiment, the R-AID can be a same value for each coordinated AP (e.g., the first coordinated AP 104, the second coordinated AP 106, and the third coordinated AP 108) in the one more APs 102. The user device (e.g., user devices 122, 124, and/or 126) can use the R-AID when performing the measurement phase with the one or more APs 102.
In one embodiment, the R-AID may be, alternatively, only valid per a coordinated AP in the one or more APs 102, but multiple R-AIDs may be temporarily assigned to the user device (e.g., user devices 122, 124, and/or 126) with the extended neighbor report. The extended neighbor report can comprise information regarding each coordinated AP in the one or more APs 102 with which location measurements are possible for the user (e.g., user devices 122, 124, and/or 126). To this end, the location capability support information can comprise, for each coordinated AP (e.g., the first coordinated AP 104, the second coordinated AP 106, and the third coordinated AP 108), a R-AID that the user device (e.g., user devices 122, 124, and/or 126) may use during the measurement phase. Additionally, the location capability support information can comprise, for each coordinated AP (e.g., the first coordinated AP 104, the second coordinated AP 106, and the third coordinated AP 108) in the one or more APs 102, a range of R-AIDs that the user devices 120 can use to perform location measurements with each of the coordinated APs. Thus, in such embodiment, the multiple R-AIDs can be different values (on a per coordinated AP basis) or a same value for some of the coordinated APs.
In one embodiment, the location capability support information (of the extended neighbor report), can comprise, for each coordinated AP in the one or more APs 102: (1) a type of location services available at a coordinated AP in the one or more APs 102 (e.g. SU/MU HE range, angular, scalable mode); (2) a time difference in the TFS between the coordinated AP and another coordinated AP in the one or more APs 102; (3) a TBTT: a time at which the coordinated AP should send its beacons; (4) a target time of service periods for location service for the negotiation phase or the measurement phase (e.g., a TWT between measurement resource requests opportunities at the another coordinated AP); and (5) capabilities for location service. Based on that information, the one or more user devices 120 may improve its scanning and coordinated AP selection for concurrent operation of location measurements and data transmissions.
In one embodiment, the location capability support information can comprise a keep-alive timeout that define a time period (e.g., a numerical value in seconds, minutes, etc.) after which the R-AID, assigned to the user device (e.g., user devices 122, 124, and/or 126) is no longer valid, unless the user device (e.g., user devices 122, 124, and/or 126) and a coordinated AP (in the one or more APs 102) performs a successful frame exchange, in which case the keep-alive timeout is reset to an original value. A coordinated AP in the one or more APs 102 may define the original value during the negotiation phase. The original value, alternatively, can be advertised in beacons and probe responses.
In one embodiment, after the user device (e.g., user devices 122, 124, and/or 126) has determined a R-AID (or multiple R-AIDs) based on the extended neighbor report, the user device may perform the measurement phase of the enhanced location service negotiation system using the R-AID. The R-AID (or the multiple R-AIDs) allows the user device to operate in DL and UL MU mode with the one or more APs 102 to determine location measurements with the one or more APs 102. As will be described in greater detail herein below, the location measurements can comprise, e.g., FTM measurements, position services, etc.
FIG. 2 depicts an illustrative flow diagram location determination using FTM, in accordance with one or more example embodiments of the present disclosure.
The example of FIG. 2 is an example negotiation and measurement exchange sequence 200 between an initiating device 210 (e.g., a coordinated AP) and a responding device 220 (e.g., a user device) for a single burst instance, where an As Soon As Possible (ASAP) field=1 and an FTMs per Burst field=3. The initiating device 210 and the responding device 220 may be associated or unassociated with one another.
In the example shown in FIG. 2, after the responding device 220 (at a negotiation phase) determines a R-AID (assigned to it or associated with it) based on an extended neighbor report, the initiating device 210 device may perform FTM measurements with the responding device 220. Specifically, the initiating device 210 may cause to send an initial FTM request 230 to the responding device 220 that comprises the R-AID. The responding device 220 may identify the initial FTM request 230 based on the R-AID. Further, the responding device 220 may cause to send, in response, an acknowledgment 232 of the initial FTM request 230. Subsequently, a series of FTM messages and acknowledgements 234 may be exchanged between the initiating device 210 and the responding device 220 using a timing synchronization function, where time measurements are taken (that correspond to how much time it takes to receive an acknowledgement based on a particular FTM measurement). The series of FTM messages and acknowledgments 234 can comprise physical layer (PHY) protocol data units (PPDUs), NDPs, etc. The initiating device 210 can compute a round trip time and a clock offset. A distance (e.g., location measurement) from the responding device 220 to the initiating device 210 can be derived based on the time measurements. It is understood that the above is only an example meant for illustrative purposes.
FIG. 3 depicts an illustrative schematic diagram for enhanced location service negotiation, in accordance with one or more example embodiments of the present disclosure.
Referring to FIG. 3, there is shown an exemplary measurement protocol 300 for the enhanced location service negotiation between a first coordinated AP 306 and a user device 324 (e.g., a STA) that can use UL MU and DL MU operations, where the enhanced location service negotiation comprises a negotiation phase 310 and a measurement phase 312. The first coordinated AP 306 can be coordinated with a second coordinated AP 304 and a third coordinated AP 308 (e.g., to provide WLAN services to the user device 324). The user device 324 may be unassociated or associated with the first coordinated AP 306.
Generally, the negotiation phase 310 can be when the user device 324 and the first coordinated AP 306 exchange capabilities and negotiate type(s) of measurements to be determined for location measurement. In the example shown in FIG. 3, during the negotiation phase 310, the first coordinated AP 306 can be configured to broadcast (or unicast) a neighbor report 314 (e.g., in a location negotiation frame) that comprises location capability support information. The location capability support information comprises identification information that the user device 324 can use when performing a FTM measurement or UL/DL sounding to the first coordinated AP 306. The user device 324 can identify neighbor report 314 and determine the location capability support information to facilitate the negotiation phase 310 between the user device 324 and the first coordinated AP 306 as well as the second coordinated AP 304 and the third coordinated AP 308 (that are coordinated among each other).
The location capability support information can comprise a R-AID that can be assigned to the user device 324 and valid when the user device 324 performs FTM measurement or UL/DL sounding with the first coordinated AP 306. The R-AID can be assigned so that it is unique to the user device 324 and may not correspond to an AID of another user device associated to the second coordinated AP 304 or to the third coordinated AP 308, or to another unassociated user device. In one embodiment, the R-AID the user device 324 can use the R-AID when performing FTM measurements or UL/DL sounding with the second coordinated AP 304 and the third coordinated AP 308.
In one embodiment, the R-AID may be, alternatively, only valid for the first coordinated AP 306 (that transmits the neighbor report 314) for the user device 324, but multiple R-AIDs may be temporarily assigned to the user device 324 with the neighbor report 314. The neighbor report 314 can comprise information regarding the second coordinated AP 304 and the third coordinated AP 308. To this end, the location capability support information can comprise, for the second coordinated AP 304 and the third coordinated AP 308, additional R-AIDs that the user device 324 may use to perform location measurement or UL/DL sounding with the second coordinated AP 304 and the third coordinated AP 308.
Subsequent to the negotiation phase 310, the measurement phase 312 can be when the user device 324 and the first coordinated AP 306 perform location measurements (e.g., by performing FTM procedures or UL/DL sounding). Particularly, in FIG. 3, a context of channel access mechanisms for the user device 324 and the first coordinated AP 306 for UL MU and DL MU is shown, where the channel access mechanisms comprise a UL sounding part 316 and a DL sounding part 318. In the UL sounding part 316, the user device 324 (and other user devices) may be triggered by the first coordinated AP 306 to send UL trigger-based MU PPDUs or NDPs. To initiate this sequence, the first coordinated AP 306 may send a trigger frame 320, indicating the R-AID that has been associated with/assigned to the user device 324 and resource allocations of the user device 324. In a conventional measurement protocol, in order to participate in the multi-user positioning illustrated in the measurement phase 312, STAs associated with the first coordinated AP 306, contrastingly, may need to have a UID and unassociated STAs may need to have an AID.
Subsequent to the first coordinated AP 306 sending the trigger frame 320, the first coordinated AP 306 may cause to send UL NDPs 322 to user devices, including the user device 324. The UL NDPs may include the R-AID that has been assigned to the user device 324, and the user device may identify a UL NDP (in the UL NDPs) based on the R-AID. Short interframe service (SIFS) periods may occur between AP transmissions as shown in FIG. 3.
After the UL sounding part 316, the DL sounding part 318 can occur. In the DL sounding part 318, the first coordinated AP 306 may cause to send a DL Null Data Packet Announcement (NDPA) 326 and a DL NDP 328 as pilot tones to the user devices, including the user device 324. The pilot tones can be used by the user device 324 (and other user devices) to estimate the channel and perform location measurements. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.
FIG. 4 depicts an illustrative schematic diagram 400 for selected opportunities for multi-channel operation.
Referring to FIG. 4, there is shown an exemplary scheduling and association activity where a user device 424 may perform location measurements with a first coordinated AP 404, a second coordinated AP 406, and a third coordinated AP 408 over, respectively, three distinct channels: channel A 412, channel B 414, and channel C 416. The user device 424 may choose from the set of opportunities a subset which meets its scheduling limitations (e.g., periods of conflicts between resources), accuracy requirements, and movement of the user device 424 (e.g., positioning requirements). Conventionally, the user device 424 is to perform a location measurement attempt (e.g., a measurement phase opportunity) in a time period on a single channel (e.g., the channel A 412, the channel B 414, or the channel C 416) that is non-overlapping with (a) attempts on other channels or (b) association conflicts on other channels.
With the introduction of HE-MU mode as one of the predominant modes of the upcoming 802.11ax or next generation Wi-Fi (Next Gen) the resulting scheduling mechanism enhances the effect where access to the channel using the legacy CSMA/CA gets lower probability. This probability may be even lower the more the medium becomes congested. Thus, meeting positioning requirements and scheduling constraints of coordinated APs in an enhanced location service negotiation system can be difficult.
As shown in FIG. 4, one or more attempts may be allocated to the user device 424 (e.g., a first attempt 432, a second attempt 434, a third attempt 436, and a fourth attempt 438) on the channel A 412. Further, the user device 424 may be allocated certain attempts (e.g., a first attempt 442, a second attempt 444, a third attempt 446, and a fourth attempt 448) on the channel B 414. In the example of FIG. 4, there are no attempts available for the user device 424 on the channel C 416.
As earlier stated, because the user device 424 is to perform an attempt on a channel when it is non-overlapping with other attempts, scheduling conflicts 452, 454 can occur. A first scheduling conflict 452 occurs when the third attempt 436 (that is selected) on the channel A 412 and the third attempt 446 on the channel B 414 overlap. A second scheduling conflict occurs 454 when the second attempt 444 on the channel B 414 overlaps with an association conflict 462 on the channel C 416. FIG. 4 additionally shows the first attempt 432 (that is selected) on the channel A 412 and the fourth attempt 448 (that is selected) on the channel B 414 as being non-overlapping phase measurement opportunities where location measurements can be performed by the user device 324. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.
FIG. 5 depicts an illustrative schematic diagram 500 for enhanced location service negotiation.
Referring to FIG. 5, there is shown an enhanced location service negotiation system 500 that comprises an AP causing to send a TF short feedback followed by a measurement phase. In one embodiment, after the AP has completed a negotiation phase with one or more STAs, the AP can be configured to cause to send a first TF short feedback (e.g., a frame) 502 that comprises location measurement identifications (e.g., R-AIDs, AIDs, or UIDs) of the one or more STAs. The first TF short feedback 502 can allow the AP and the one or more STAs to meet positioning requirements and avoid scheduling conflicts (as described along with FIG. 4) that may arise during location determinations. Particularly, the one or more STAs can respond (e.g., in a response frame) to the first TF short feedback 502 to indicate that the one or more STAs have capabilities and availability to perform a location measurement (or fail to reply for, e.g., being out of range or unavailable). Based on the response of the one or more STAs, the AP can allocate a space reuse code dimension 504 (e.g., frequency domains, RU dimensions, etc.) to the one more STAs that indicated that they are available to perform the timing measurement. The space reuse code dimension 504 can comprise measurement phase opportunities to the one or more STAs that do not conflict with other measurement phase opportunities. Subsequently, the AP may perform a measurement phase 506 that is substantially similar to what is described along with FIG. 3. More particularly, the AP may be configured to perform location measurements and/or UL/DL sounding with the one or more STAs, wherein frames comprise R-AIDs that have been assigned to the one more STAs through a neighbor report. Following the measurement phase 506, the STA may cause to send a second TF short feedback 508 (that determines whether the one or more APs are available for another measurement phase). A reference to timing of one or more future short feedback allocation 510 may be used in between the first TF short feedback 502 and the second TF short feedback 508.
In one embodiment, if location measurement is not requested by the user device using the R-AID in an FTM Resource Request mechanism (e.g., using a NDP Short Feedback for FTM measurement), then the aforementioned R-AID is released and a new negotiation phase of the enhanced location service negotiation system is established. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.
FIG. 6 illustrates a flow diagram of illustrative process 600 for an illustrative enhanced location service negotiation system, in accordance with one or more example embodiments of the present disclosure.
At block 602, a device may identify a neighbor report frame received from one or more coordinated APs, wherein the neighbor report frame comprises location capability support information. For example, the location capability support information comprises identification information that the device can use when performing an FTM measurement with the one or more of coordinated APs. The location capability support information can be used by the device to facilitate a negotiation phase of an enhanced location service negotiation system. The location capability support information can be a modified portion (or an additional portion) of a conventional neighbor report (e.g., the Neighbor Report defined in IEEE 802.11k) that comprises information indicating capabilities of each AP in the one or more coordinated APs.
At block 604, the device may determine a first R-AID associated with the location capability support information. Particularly, the location capability support information can comprise the first R-AID that can be assigned to the device and valid, when the device performs FTM measurement, for each AP in the one or more coordinated APs. The first R-AID can be assigned so that it is unique to the STA and may not correspond to an associated ID (AID) of another STA associated to another AP of the one or more coordinated APs or to another unassociated STA within the one or more coordinated APs. Alternatively, the location capability support information can comprise, for each AP of the one or more coordinated APs, multiple R-AIDs (or a range of R-AIDs) that the STA may use to perform location measurement with the each AP of the one or more coordinated APs. Thus, the multiple R-AIDs can be different values (on a per coordinated AP basis) or a same value for some of the coordinated APs. The device can determine that first R-AID based on the location capability support information. The location capability support information may additionally comprise a keep-alive timeout(s) that can be associated with the (multiple) R-AIDs.
At block 606, the may device determine a first location measurement with a first coordinated AP of the one or more coordinated APs and a second location measurement with a second coordinated AP of the one or more coordinated APs using the first R-AID. For example, the device can perform a measurement phase with the one more coordinated APs. Particularly, as described above, the device may determine the first location measurement and the second location measurement using a location determination using FTM and/or measurement protocol. Further, the device may, prior to determining the first location measurement or the second location measurement, receive a TF short feedback from the one or more coordinated APs to, e.g., avoid scheduling conflicts and meet positioning requirements. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.
FIG. 7 illustrates a flow diagram of illustrative process 700 for an illustrative enhanced location service negotiation system, in accordance with one or more example embodiments of the present disclosure.
At block 702, a device may determine a neighbor report frame, wherein the neighbor report frame comprises location capability support information, wherein the location capability support information comprises a first R-AID associated with a first coordinated AP of one or more coordinated APs. For example, the location capability support information comprises identification information that a second device can use when performing an FTM measurement with the device. The location capability support information can be used by the second device to facilitate a negotiation phase of an enhanced location service negotiation system. The location capability support information can be a modified portion (or an additional portion) of a conventional neighbor report (e.g., the Neighbor Report defined in IEEE 802.11k) that comprises information indicating capabilities of each AP in the one or more coordinated APs. The location support capability support information, as described above, may additionally comprise additional R-AIDs (associated with at least a second coordinated AP of the one or more coordinated APs), a keep-alive timeout associated with the first R-AID, etc.
At block 704, the device may cause to send the neighbor report frame. The device may cause to send the neighbor report frame, e.g., using any of the communication protocols described herein. For example, the device may unicast or broadcast the neighbor report frame to the second device.
At block 706, the device may determine a location measurement of the first coordinated AP of the one or more coordinated APs and a device using the first R-AID. For example, the device can perform a measurement phase with the second device. Particularly, as described above, the device may determine the first location measurement and the second location measurement using a location determination using FTM and/or measurement protocol. Further, the device may, prior to determining the first location measurement, cause to send a TF short feedback to the second device to, e.g., determine scheduling conflicts and positioning requirements of the second device. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

FIG. 9 illustrates a block diagram of an example of a machine 900 or system upon which any one or more of the techniques (e.g., methodologies) discussed herein may be performed. In other embodiments, the machine 900 may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine 900 may operate in the capacity of a server machine, a client machine, or both in server-client network environments. In an example, the machine 900 may act as a peer machine in peer-to-peer (P2P) (or other distributed) network environments. The machine 900 may be a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a mobile telephone, a wearable computer device, a web appliance, a network router, a switch or bridge, or any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine, such as a base station. Further, while only a single machine is illustrated, the term machine shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein, such as cloud computing, software as a service (SaaS), or other computer cluster configurations.
The machine (e.g., computer system) 900 may include a hardware processor 902 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory 904 and a static memory 906, some or all of which may communicate with each other via an interlink (e.g., bus) 908. The machine 900 may further include a power management device 932, a graphics display device 910, an alphanumeric input device 912 (e.g., a keyboard), and a user interface (UI) navigation device 914 (e.g., a mouse). In an example, the graphics display device 910, alphanumeric input device 912, and UI navigation device 914 may be a touch screen display. The machine 900 may additionally include a storage device (i.e., drive unit) 916, a signal generation device 918 (e.g., a speaker), an enhanced location service negotiation device 919, a network interface device/transceiver 920 coupled to antenna(s) 930, and one or more sensors 928, such as a global positioning system (GPS) sensor, a compass, an accelerometer, or other sensor. The machine 900 may include an output controller 934, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate with or control one or more peripheral devices (e.g., a printer, a card reader, etc.)).
The storage device 916 may include a machine readable medium 922 on which is stored one or more sets of data structures or instructions 924 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 924 may also reside, completely or at least partially, within the main memory 904, within the static memory 906, or within the hardware processor 902 during execution thereof by the machine 900. In an example, one or any combination of the hardware processor 902, the main memory 904, the static memory 906, or the storage device 916 may constitute machine-readable media.
The enhanced location service negotiation device 919 may carry out or perform any of the operations and processes (e.g., process 600) described and shown above. The enhanced location service negotiation device 919 may define an enhanced FTM protocol for positioning service between a group of coordinated APs and one STA using an extended neighbor report (that comprises at least one R-AID). That STA may be either associated with only one of the APs of the group or an unassociated STA to all.
In another example, the enhanced location service negotiation device 919 may be configured to identify a neighbor report frame received from one or more coordinated access points (APs), wherein the neighbor report frame comprises location capability support information; determine a first ranging associated ID (R-AID) associated with the location capability support information; and determine a first location measurement with a first coordinated AP of the one or more coordinated APs and a second location measurement with a second coordinated AP of the one or more coordinated APs using the first R-AID.
The enhanced location service negotiation device 919 may enhance FTM negotiation to support establishment of an FTM measurement to more than a single AP. Once a single negotiation is established, the STA may then choose one or more possible opportunities, which may meet their positioning requirements and scheduling constraints. If a positioning measurement is not requested by the STA using the R-AID on the FTM Resource Request mechanism (e.g. using the NDP Short Feedback for FTM Range measurement), the context is released and a new FTM negotiation needs to be established.
It is understood that the above are only a subset of what the enhanced location service negotiation device 919 may be configured to perform and that other functions included throughout this disclosure may also be performed by the enhanced location service negotiation device 919.
While the machine-readable medium 922 is illustrated as a single medium, the term machine-readable medium may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 924.
Various embodiments may be implemented fully or partially in software and/or firmware. This software and/or firmware may take the form of instructions contained in or on a non-transitory computer-readable storage medium. Those instructions may then be read and executed by one or more processors to enable performance of the operations described herein. The instructions may be in any suitable form, such as but not limited to source code, compiled code, interpreted code, executable code, static code, dynamic code, and the like. Such a computer-readable medium may include any tangible non-transitory medium for storing information in a form readable by one or more computers, such as but not limited to read-only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; a flash memory, etc.
The term machine-readable medium may include any medium that is capable of storing, encoding, or carrying instructions for execution by the machine 900 and that cause the machine 900 to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding, or carrying data structures used by or associated with such instructions.
