Description

[Technical Field]

[0001] The present disclosure relates to estimating the position of one or more user devices or automated guided vehicles in a telecommunications and / or wireless network. In particular, the present disclosure relates to methods, apparatus, and systems for estimating the position of one or more user devices or automated guided vehicles in a telecommunications and / or wireless network. [Background technology]

[0002] In telecommunications networks, accurate measurement of device location is critical for the continuous and efficient provision of network services. Determining the location of user devices, autonomous guided vehicles, or portable network devices frequently uses line-of-sight (LOS)-based signaling methods. Such methods may be satisfactory in outdoor areas where LOS signals can be easily transmitted or received. However, in areas where it may be more difficult to transmit LOS signals, such as indoor areas or outdoor areas with obstructions, methods using LOS signaling may be highly error-prone.

[0003] Therefore, there is a need for a method to improve the positioning accuracy of a user device or an automated guided vehicle that may not be within line of sight of a telecommunications network.

[0004] Telecommunications networks are increasingly relying on cloud computing and artificial intelligence methods to accommodate the expansion of services, customers, and areas of operations. However, there has been no significant research examining how artificial intelligence methods can be used to improve the location accuracy of user devices, especially in areas where line of sight is difficult to find.

The second processor is part of user premises equipment. The program may further include first receiving code configured to cause the first processor to receive a ranging result report. The ranging result report calculated by the user device includes distance and timing information associated with signals received by the user device. The program may further include third transmitting code configured to cause the first processor to transmit a location of the user device.

[0019] The following detailed description of the exemplary embodiments refers to the accompanying drawings, in which the same reference numbers in different drawings may refer to the same or similar elements.

[0020] The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the implementations to the precise forms disclosed. Modifications and variations are possible in light of the above disclosure or may be acquired from practicing the implementations.

[0021] It will be apparent that the systems and / or methods described herein may be implemented in various forms of hardware, firmware, or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and / or methods is not intended to limit the implementation. Thus, the operation and behavior of the systems and / or methods are described herein without reference to specific software code, and it will be understood that software and hardware can be designed to implement the systems and / or methods based on the description herein.

[0022] As is conventional in the art, the embodiments may be described and illustrated with blocks that perform one or more described functions. These blocks, sometimes referred to herein as units, modules, or the like, may be physically implemented by analog or digital circuitry, such as logic gates, integrated circuits, microprocessors, microcontrollers, memory circuits, passive electronic components, active electronic components, optical components, hardwired circuits, etc., and may be driven by firmware and software, optionally by firmware. The circuits may be embodied, for example, in one or more semiconductor chips or on a substrate support such as a printed circuit board. The circuits included in the blocks may be implemented by dedicated hardware, by a processor (e.g., one or more programmed microprocessors and associated circuitry), or by a combination of dedicated hardware for performing some functions of the block and a processor for performing other functions of the block. Each block of the embodiments may be physically separated into two or more interacting individual blocks. Similarly, the blocks of the embodiments may be physically combined into more complex blocks.

[0023] Although particular combinations of features are recited in the claims and / or disclosed herein, these combinations are not intended to limit the disclosure of possible implementations. Indeed, many of these features may be combined in ways not specifically recited in the claims and / or disclosed herein. Although each dependent claim listed below may depend directly on only one claim, in the disclosure of possible implementations, each dependent claim includes all other claims recited in the claims.

[0024] No element, act, or instruction used herein should be construed as critical or required unless explicitly described as such. Also, as used herein, the articles "a" and "an" are intended to include one or more items and may be used interchangeably with "one or more." Where only one item is intended, the term "one" or similar language is used. Also, as used herein, terms such as "has," "have," "having," "include," and "including" are intended to be open-ended terms. Furthermore, the phrase "based on" is intended to mean "based at least in part on," unless specifically stated otherwise.

[0025] As described above, accurate positioning of user devices and network devices is important for providing continuous and efficient service to users of telecommunications networks. Determining the location of devices that are not necessarily within the line of sight (LOS) of the telecommunications network, such as devices located in indoor areas or in obstructed areas, is highly error-prone due to the lack of LOS signaling. Position Reference Signals (PRSs) may be primarily used by network elements (e.g., gNodeBs, eNodeBs, centralized units, distributed units) to determine the location of user devices. PRSs move in straight lines and may be redirected or reoriented when bouncing off surfaces. This reorientation often makes the PRS's relative time and distance measurements inaccurate. The inaccuracies result in service disruptions for some customers, reducing customer satisfaction and increasing the inefficiency of the telecommunications network. Therefore, a method or system that can be used in either LOS or non-line-of-sight (NLOS) conditions is needed.

[0026] The use of artificial intelligence methods to analyze various aspects of telecommunications networks has significantly improved the efficiency of telecommunications networks. However, such artificial intelligence techniques have not yet been utilized for real-time positioning of user equipment in telecommunications networks. Therefore, there may be a need for methods and systems, particularly those that utilize artificial intelligence, in the context of determining the location of network devices and / or user equipment in a communication system.

[0027] Embodiments of the present disclosure relate to an adaptive method for determining the real-time location of a user equipment, especially in areas where there may be many obstacles that make the use of a PRS difficult. As mentioned above, a PRS is a position reference signal that supports downlink / uplink positioning. According to embodiments, the location of a user equipment may be determined using a combination of one or more PRSs from one or more network elements and sidelink reference signals (SLRSs) from one or more network devices whose locations are known.

[0028] The one or more network devices with known locations may include local network devices that provide network services. By way of example, the network devices may include user premises equipment or fixed wireless access equipment that are mostly fixed in locations close to the user. In areas where it is difficult to use PRS because network elements are not within the user device's line of sight, the fixed-location network devices with known locations may be used to determine the user equipment's location. The relative location of the user equipment from the fixed-location network devices may be used to determine the user equipment's location relative to the fixed-location network devices. This relative location of the user equipment may then be used to find the user equipment's location relative to the network elements (e.g., gNodeBs) by adjusting the relative locations of the network devices relative to the network elements. The user equipment's location may then be used to provide continuous and efficient service to the user equipment, even when the user device is not within the line of sight of the network elements.

[0029] According to some embodiments of the present disclosure, an adaptive method for determining a user device's location can include using a machine-learned, customizable location inference model. The location inference model can determine the user device's precise location using multiple artificial intelligence methods. The location inference model may be trained on a core network element or a central processor of a telecommunications network. The machine-learned location inference model can be deployed to infer the user device's location on a regional processor (e.g., a network element) or on the user equipment itself. Transferring the location inference model to a network element or user equipment can reduce transmission delays and overhead when determining the user device's location on a telecommunications network, increasing the overall efficiency of the process. Transferring an inference-only location inference model to a network element or user equipment can also enable detailed customization of the local inference model while maintaining user privacy. Essentially, having a local machine-learned location inference model on a network element or user equipment can result in more accurate and secure positioning of the user device by taking into account the specific patterns of the local network.

[0030] Embodiments of the present disclosure may enable real-time updates of the position and / or location of user equipment or network devices, such as automated guided vehicles (AGVs) or Internet of Things (IoT) enabled devices, efficiently without taxing the resources of telecommunications networks.

[0031] FIG. 1 is an example diagram of a network architecture 100 in which the systems and / or methods described in this disclosure may be implemented.

[0032] 1, telecommunications network 100 may include network element 101, one or more obstacles 105 (e.g., 105-1, 105-2, and 105-3), one or more user premise equipment (user premise equipment) 104 (e.g., 104-1 and 104-2), one or more user equipment, such as user device 103, and AGV 102. As shown in FIG. 1, telecommunications network 100 may be located in an environment that includes multiple obstacles (obstacles 105). The obstacles may make direct line-of-sight communication or positioning between the equipment (user device 103 or AGV 102) and network element 101 difficult.

[0033] According to embodiments of the present disclosure, a network element 101 can determine the position and / or location of a user equipment in order to continuously and efficiently provide network services in a telecommunications network. A network element may include any facility or equipment used to provide network services in a telecommunications network. By way of example, the network element 101 may include cell towers, cell sites, base stations (e.g., gNodeBs, eNodeBs, central or distributed units, E-UTRA cells, etc.). In some embodiments, if the real-time location of the user equipment may be needed, the network element 101 may periodically or adaptively update the user equipment location. By way of example, when media may be streamed or generated to the user device 103, knowing the user equipment location can improve the efficiency of media exchange between the network element 101 and the user device 103.

[0034] To determine or update the location of the user equipment, the network element may use an LOS signaling method. For example, the network element may use a PRS to determine or update the location of the user equipment. Any known protocol may be used to define and configure the PRS. For example, the New Radio Positioning Protocol A (NRPPa) may be used to define and configure the PRS. In some embodiments, the PRS definition or configuration may include a positioning frequency layer, a resource set, and a sequence ID. In some embodiments, the PRS definition or configuration may include a PRS positioning frequency layer that may include a set of PRS resource sets, where each PRS resource set defines a set of PRS resources. In some embodiments, the PRS definition or configuration may include slot configuration parameters, where a carrier grid may be plotted at the slot level to highlight the slots in which the PRS resource sets reside. A slot may refer to a specific space in a radio frame, and the slot configuration parameters may include a higher layer sequence ID that may be mapped to a specific slot. According to some embodiments, a PRS may be used to transmit or determine timing information associated with a PRS being received or transmitted by a user device using an Observed Time Difference Of Arrival (OTDOA) parameter of the signal.

[0035] The environment of the user equipment may include multiple obstacles that may block the direct path between the network element and the user equipment. The obstacles may include man-made obstacles such as walls, buildings, or natural obstacles such as trees, mountains, hills, etc.

[0036] As described above, a network element can use a PRS to determine the location of a user device. However, a PRS requires a direct line of sight, and the presence of an obstacle that blocks the line of sight between the network element and the user device can cause errors when determining the location of the user device. For example, in FIG. 1, user device 103 may not be within line of sight of network element 101 due to obstacle 105-1. Therefore, when a network element broadcasts a PRS, the signal may bounce significantly after colliding with obstacle 105-1 or be diverted after colliding with obstacle 105-3. Even if the PRS reaches and communicates with user device 103 after colliding with obstacle 105-3, the distance and directivity calculated based on the PRS's path may be incorrect.

[0037] A telecommunications network may include one or more user premises equipment. User premises equipment may include any equipment that provides services related to a telecommunications network, such as a telephone, a modem, a router, a wireless access point device, an adapter for a network device, a local area network (LAN), a wide area network (WAN) device, etc. By way of example, in telecommunications network 100, user premises equipment 104 (e.g., user premises equipment 104-1 or 104-2) may be a router, a modem, or a fixed wireless access device.

[0038] According to embodiments of the present disclosure, user premises equipment may be located at either a fixed position or a position and / or location known to the telecommunications network. The user premises equipment can communicate with other network devices or user equipment using a sidelink reference signal (SLRS) without going through a network element. As an example, the first user premises equipment 104-1 and the second user premises equipment 104-2 may communicate with each other, the user device 103, and the AGV 102 directly using the SLRS without going through the network element 101. The SLRS can be used to measure the distance between the user equipment and the user premises equipment based on Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or beam information. In some embodiments, the user equipment can generate a ranging result report based on the SLRS. The SLRS can be defined and configured using any suitable or known protocol. In some embodiments, the user premises equipment can report the distance and / or directionality between the user premises equipment and the user equipment to a network element or a core network element. As described above, a combination of an SLRS and a PRS can be used to determine the location of the user equipment. To combine information from both the PRS and the SLRS when determining the location of the user equipment, the user premises equipment can correlate each PRS with each SLRS associated with the user equipment. In some embodiments, a ranging result report can be based on the SLRS and the associated / correlated PRS. As an example, an SLRS can be correlated with a PRS, and signals can be associated with the same location measurement time based, for example, on a first transaction ID associated with the PRS being the same as a second transaction ID associated with the SLRS.

[0039] According to some embodiments, the ranging result report may include one or more of the following: a time lag between transmission and reception of the SLRS between the user equipment and the user premises equipment, location information associated with the user premises equipment, power information associated with the user equipment, power information associated with the user premises equipment, a time of arrival of the SLRS, or angle information associated with reception of the SLRS. In some embodiments, the ranging result report may include signal information associated with the PRS. The signal information may include at least one of sequence ID information associated with the PRS and a beam index received by the user equipment associated with the PRS.

[0040] A telecommunications network may include one or more user equipment. User equipment may be any user device that uses services provided by the telecommunications network. Examples of user equipment may include Industrial Internet of Things (IIoT) devices (e.g., smart sensors, etc.), personal computing devices, user mobile devices, user Internet of Things enabled devices, and automated guided vehicles (e.g., drones, dedicated robots, autonomous vehicles, etc.). By way of example, in telecommunications network 100, user equipment may include user device 103 and AGV 102. In some embodiments, user equipment may be controlled by users of the telecommunications network to use network services or by operators of the telecommunications network to maintain the telecommunications network.

[0041] In an exemplary embodiment, the first user premises equipment 104-1 or the second user premises equipment 104-2 can use the SLRS to determine the distance and / or directionality between the first user premises equipment 104-1 or the second user premises equipment 104-2 and the user device 103 and the AGV 102 based on the RSRP, RSSI, RSRQ, and / or beam information from the received SLRS.

[0042] According to embodiments of the present disclosure, a telecommunications core network element can be used to determine the location of a user equipment in a LOS or NLOS setting. The core network element can include a central processing unit responsible for performing critical functions in a telecommunications network. Critical functions can include maintaining subscriber information, call switching, service authorization, and / or location services. In some embodiments, the core network element can trigger a process to determine the location of a user equipment. The network element can transmit a PRS to the user equipment upon receiving a positioning trigger signal from the core network element. Because core network elements perform critical functions, they generally have robust computing capabilities (more storage, faster processors, more data, etc.) compared to network elements. Thus, in some embodiments, the core network element can be used by a location management function to train and / or deploy models to infer the location of a user equipment. The location management function can use the core network element to train a location inference model using data from across the communication network, leveraging the robust computing resources of the core network element.

[0043] In some embodiments, a telecommunications network may include a Location Management Function (LMF) that can train and deploy machine-learned location inference models that determine the location of user equipment. The LMF may train the location inference models using data from across the telecommunications network. In some embodiments, the LMF may train the location inference models for adaptive indoor positioning of user equipment. According to embodiments of the present disclosure, training data for training the location inference models may include SLRS measurements, estimated positions of user equipment, user premises equipment locations, PRS, sounding reference signals, and timing information associated with signals received by the user equipment.

[0044] In some embodiments, the LMF may also deploy machine-learned or trained location inference models to core network elements. In some other embodiments, the LMF may generate an inference model based on the machine-learned location inference model and send the generated inference to a sub-location management function at the network element or user equipment where the location is being determined. The location of the user device may be carefully calculated by the network element or user equipment based on the inference model and ranging result reports generated by the user equipment. Forwarding the machine-learned location inference model to the sub-LMF (sub-LMF) for inference simply reduces the overall transmission delay and overhead while determining the location of the user equipment.

[0045] In an exemplary embodiment, a trained or machine-learned location inference model can be used in conjunction with the PRS and SLRS to determine the real-time position and / or location of the user device 103. The first user premises equipment 104-1 can report the distance between the user premises equipment 104-1 and the user device 103, along with other information, to a core network element of a telecommunications network. The reported distance between the first user premises equipment 104-1 and the user device 103 can be correlated to a PRS transmitted by the network element to the user device 103. The position or location of the user device can be determined based on the reported distance between the first user premises equipment 104-1 and the user device 103 and information related to the correlated PRS.

As shown in FIG. 2, environment 200 may include a device 210, a platform 220, and a network 230. The devices of environment 200 may be interconnected by wired connections, wireless connections, or a combination of wired and wireless connections. In an embodiment, any of the functions of the elements included in telecommunications network 100 may be performed by any combination of the elements shown in FIG. 2.

[0047] Device 210 includes one or more devices that can receive, generate, store, process, and / or provide information related to platform 220. For example, device 210 may include a computing device (e.g., a desktop computer, a laptop computer, a tablet computer, a handheld computer, a smart speaker, a server, etc.), a mobile phone (e.g., a smartphone, a wireless phone, etc.), a wearable device (e.g., smart glasses or a smart watch), or a similar device. In some implementations, device 210 can receive information from and / or transmit information to platform 220. In some embodiments, device 210 can include network element 101, user premises equipment 104, user device 103, or AGV 102.

[0048] Platform 220 includes one or more devices capable of providing network services, as described elsewhere herein. In some implementations, platform 220 may include a cloud server or a collection of cloud servers. In some implementations, platform 220 may be designed modularly so that specific software components can be swapped out depending on specific needs. Thus, platform 220 can be easily and / or quickly reconfigured for various uses.

[0049] In some implementations, as shown, platform 220 may be hosted in a cloud computing environment 222. Notably, although the implementations described herein describe platform 220 as being hosted in a cloud computing environment 222, in some implementations platform 220 may not be cloud-based (i.e., may be implemented outside of a cloud computing environment) or may be partially cloud-based.

[0050] Cloud computing environment 222 includes an environment that hosts platform 220. Cloud computing environment 222 may provide services such as computation, software, data access, and storage that do not require end-user (e.g., device 210) knowledge of the physical location and configuration of the systems and / or devices that host platform 220. As shown, cloud computing environment 222 may include a collection of computing resources 224 (which may be referred to collectively or individually as “computing resources 224”).

[0051] Computing resources 224 include one or more personal computers, workstation computers, server devices, or other types of computing and / or communication devices. In some implementations, computing resources 224 can host platform 220. Cloud resources may include compute instances executing within computing resources 224, storage devices provided within computing resources 224, data transfer devices provided by computing resources 224, etc. In some implementations, computing resources 224 may communicate with other computing resources 224 via wired connections, wireless connections, or a combination of wired and wireless connections.

[0052] As further shown in FIG. 2 , computing resources 224 include a group of cloud resources, such as one or more Applications (“APPs”) 224-1, one or more Virtual Machines (“VMs”) 224-2, Virtualized Storage (“VSs”) 224-3, and one or more Hypervisors (“HYPs”) 224-4. Application 224-1 includes one or more software applications that can be provided by or accessed by device 210. Application 224-1 may obviate the need to install or run a software application on device 210. For example, application 224-1 may include software associated with platform 220 and / or some other software that can be provided through cloud computing environment 222. In some implementations, one application 224-1 may send or receive information to one or more other applications 224-1 via virtual machine 224-2.

[0053] Virtual machine 224-2 comprises a software-implemented machine (e.g., a computer) that executes programs like a physical machine. Virtual machine 224-2 can be either a system virtual machine or a process virtual machine, depending on the application and the degree to which virtual machine 224-2 matches an actual machine. A system virtual machine can provide a complete system platform that supports the execution of a complete operating system ("OS"). A process virtual machine can execute a single program and support a single process. In some implementations, virtual machine 224-2 can run on behalf of a user (e.g., device 210) and manage the infrastructure of cloud computing environment 222, such as data management, synchronization, or long-term data transfer.

[0054] Virtualized storage 224-3 includes one or more storage systems and / or one or more devices that use virtualization technology within the storage systems or devices of computing resources 224. In some implementations, in the case of a storage system, types of virtualization may include block virtualization and file virtualization. Block virtualization may refer to the abstraction (or separation) of logical storage from physical storage such that the storage system can be accessed regardless of the physical storage or heterogeneous structure. The separation may allow administrators flexibility in how they manage the storage for end users. File virtualization can eliminate the dependency between data accessed at the file level and where the file is physically stored. This may enable optimization of storage usage, server consolidation, and / or non-disruptive file migrations.

[0055] Hypervisor 224-4 can provide hardware virtualization technology that allows multiple operating systems (e.g., "guest operating systems") to run simultaneously on a host computer, such as computing resource 224. Hypervisor 224-4 can present a virtual operating platform to the guest operating systems and can manage the execution of the guest operating systems. Multiple instances of different operating systems can share virtualized hardware resources.

[0056] Network 230 may include one or more wired and / or wireless networks. For example, network 230 may include a cellular network (e.g., a fifth-generation (5G) network, a long-term evolution (LTE) network, a third-generation (3G) network, a code division multiple access (CDMA) network, etc.), a public land mobile network (PLMN), a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a telephone network (e.g., a public switched telephone network (PSTN)), a private network, an ad hoc network, an intranet, the Internet, an optical fiber-based network, etc., and / or a combination of these or other types of networks.

[0057] The number and arrangement of devices and networks shown in Figure 2 are provided as an example. In practice, there may be additional, fewer, different, or differently arranged devices and / or networks. Furthermore, two or more devices shown in Figure 2 may be implemented within a single device, or a single device shown in Figure 2 may be implemented as multiple distributed devices. Additionally, or instead, a set of devices (e.g., one or more devices) of environment 200 may perform one or more functions described as being performed by another set of devices in environment 200.

[0058] 3 is a diagram of example components of a device 300. Device 300 may correspond to device 210 and / or platform 220. As shown in FIG. 3, device 300 may include a bus 310, a processor 320, a memory 330, a storage component 340, an input component 350, an output component 360, and a communication interface 370.

[0059] The bus 310 includes components that enable communication between the components of the device 300. The processor 320 is implemented in hardware, firmware, or a combination of hardware and software. The processor 320 is a central processing unit (CPU), graphics processing unit (GPU), accelerated processing unit (APU), microprocessor, microcontroller, digital signal processor (DSP), field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), or another type of processing component.

[0067] 4, 6, and 8 are exemplary diagrams of network architectures for adaptive positioning accuracy of user equipment in telecommunications networks.

[0068] As shown in FIG. 4, the telecommunications network 400 may include a network element 101, a core network element 405, a regional network element (Regional NE) 401, user premises equipment 104, and a user device 103.

[0069] In embodiments, the LMF may be included in a core network element. The LMF may be configured to train a location inference model and deploy the trained location inference model to the core network element. The core network element may use the deployed machine learning location inference model to determine / calculate a location of the user equipment. In some embodiments, the core network element may use ranging result reports generated by the user equipment to determine / calculate a location of the user equipment.

[0070] As an example, the LMF may be located in the core network element 405, and the LMF may be configured to train and deploy the trained location reasoning model at the core network element 405. The machine-learned location reasoning model may be deployed to the core network element 405, such that the core network element 405 can determine the location of the user device 103 based on the machine-learned location reasoning model. In some embodiments, the core network element 405 can determine the location of the user device 103 based on a ranging result report generated by the user device 103, which the core network element 405 may receive from the user device 103.

[0071] An exemplary workflow for determining the location of a user equipment when the LMF may be located in a core network element and the core network element calculates the location of the user equipment is shown in FIG.

[0072] As seen in FIG. 5, workflow process 500 may show one or more operations for determining the location of a user equipment when the LMF may be located in a core network element and the core network element calculates the location of the user equipment.

[0073] At operation 505, the network element may transmit a positioning trigger signal (PTS) to the user equipment. In some embodiments, at operation 505, the network element may transmit the positioning trigger signal based on or subsequent to receiving an initial trigger signal from a core network element. The positioning trigger signal may be a broadcast signal indicating the start of process 500. In some embodiments, the positioning trigger signal may be the same as the initial trigger signal.

[0074] As an example, the network element 101 can transmit a positioning trigger signal to the user device 103. In some embodiments, the network element 101 can transmit the positioning trigger signal to the user device 103 based on or subsequent to receiving an initial trigger signal from the core network element 405.

[0075] At operation 510, the network element may transmit a Positioning Reference Signal (PRS) to the user equipment. In some embodiments, the PRS may be transmitted in the same operation as the PTS. According to embodiments of the present disclosure, the PRS may include information regarding the PRS resource and resource set, sequence ID information associated with the PRS, or a beam index received by the user device associated with the PRS (the user device to which the PRS may be transmitted). In some embodiments, the PRS may also include a transaction ID, which is associated with a position measurement time or user device whose position is being determined and / or calculated. As mentioned above, embodiments of the present disclosure relate to determining the position of a user equipment / user device utilizing a combination of a PRS and an SLRS. Correlation between a PRS and an SLRS associated with the same device may be required to ensure that signals associated with the same user equipment / user device are being used to determine the position.

[0076] As an example, the network element 101 may transmit a PRS to the user device 103. In some embodiments, the PRS may include a first transaction ID that may be used to correlate the PRS with the SLRS. In embodiments, the first transaction ID may be associated with the time at which the location measurement was triggered. In some other embodiments, the first transaction ID may be associated with the user device 103 whose location is being determined.

[0077] In operation 515, the user premises equipment may transmit a Sidelink Reference Signal (SLRS) to the user equipment whose position is being determined. Correlation between the PRS and the SLRS, or correlated positioning reference signal information, may be required or signaled to ensure that signals associated with the same user equipment / user device are being used to determine the position of the user equipment / user device. In some embodiments, the SLRS may also include a transaction ID, which is associated with the position measurement time or user device whose position is being determined and / or calculated. In some other embodiments, the SLRS may include correlated PRS information, which may include information related to the PRS transmitted by the network element to the user equipment.

[0078] As an example, the user premises equipment 104 may transmit an SLRS to the user device 103. In some embodiments, the SLRS may include a second transaction ID that may be used to correlate the PRS and the SLRS. In embodiments, the second transaction ID may be associated with the time (hour) at which the location measurement was triggered. In some other embodiments, the second transaction ID may be associated with the user device 103 whose location is being determined.

[0079] At operation 520, the user equipment may generate a ranging result report based on the SLRS. In some embodiments, the ranging result report may include one or more distance calculations between the user equipment and the user premises equipment based on the SLRS. The ranging result report may include correlated positioning reference signal information, where the correlated positioning reference signal information may include information associated with a positioning reference signal having a first transaction ID that is the same as a second transaction ID associated with the sidelink reference signal. In some embodiments, the first transaction ID and the second transaction ID are associated with the same position measurement time or the same user device. In some embodiments, the ranging result report may include Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or beam information associated with the received SLRS. The RSRP, RSSI, RSRQ, and / or beam index may be used to measure the distance or directionality between the user equipment and the user premises equipment.

[0080] The user equipment may transmit the generated ranging result report to a core network element at operation 525. As an example, the user device 103 may transmit the ranging result report to the core network element 405.

[0081] At operation 530, the core network element may determine and / or calculate the position of the user equipment based on the ranging result report and the machine-learned position inference model. According to some embodiments of the present disclosure, a Location Management Function (LMF) may be located in the core network element and configured to train and deploy the trained position inference model. The machine-learned position inference model may be deployed in the core network element so that the core network element can use it to determine and / or calculate the position of the user equipment. The determined and / or calculated position of the user equipment may be the initial position of the user equipment or an updated and / or revised position of the user equipment. In some embodiments, the position and / or location of the user equipment determined by the core network element may be the absolute position of the user equipment (e.g., geographic coordinates) or the relative position of the user equipment with respect to the core network element or the nearest network element.

[0082] As an example, the core network element 405 can determine and / or calculate the location of the user device 103 based on ranging result reports received from the user device 103 and a machine-learned location inference model trained and deployed by the LMF at the core network element 405.

[0083] In operation 535, the core network element and / or network element may transmit the determined location of the user equipment throughout the telecommunications network, as appropriate.

[0084] Referring now to FIG. 6, as shown in FIG. 6, a telecommunications network 600 may include a network element 101, a core network element 405, a regional network element 401, a user premises equipment 104, and a user device 103.

[0085] In embodiments, the LMF may be included in a core network element. However, the LMF may be configured only to train the location inference model based on data generated throughout the telecommunications network. Thus, the core network element may include only the model training stage of the location inference model. The core network may generate an inference model based on the machine-learned location inference model trained by the LMF. The core network element may transmit the inference model to lower layer nodes of the telecommunications network 600. Moving the generated inference model to lower layers may reduce positioning latency and reduce network traffic load for collecting information for training. In some embodiments, the network element may receive ranging result reports from the user equipment. The network element may use the inference model and ranging result reports to determine and / or calculate the location of the user equipment.

[0086] As an example, the core network element 405 can transmit an inference model to a sub-LMF at the network element 101, and the network element 101 can not train the transferred inference model but only apply it to determine the location of the user device 103. Because the inference model can be located at the sub-LMF of the network element 101, the network element 101 can determine the location of the user device 103 based on the transferred inference model. In some embodiments, the network element 101 can determine the location of the user device 103 based on a ranging result report generated by the user device 103, which the network element 101 can receive from the user device 103.

[0087] An exemplary workflow for determining the location of a user equipment where the LMF may be located in a core network element, but the network element calculates the location of the user equipment, is shown in FIG.

[0088] As seen in FIG. 7, workflow process 700 may show one or more operations for determining the location of a user equipment when the LMF may be located in a core network element and the network element calculates the location of the user equipment.

[0089] Operations 705 to 720 of the workflow process 700 are similar to operations 505 to 520 of the workflow process 500 .

[0090] In operation 725, the user equipment may transmit the generated ranging result report to a network element. Thus, in contrast to operation 525, the ranging result report may be transmitted to a network element. As an example, the user device 103 may transmit the ranging result report to the network element 101.

[0091] At operation 730, the network element may determine and / or calculate the location of the user equipment based on the ranging result report and the forwarded inference model, where the forwarded inference model is based on a machine-learned location inference model. According to some embodiments of the present disclosure, a location management function (LMF) may be located in the core network element and configured to train the location inference model. However, the LMF may be configured to generate the inference model based on the machine-learned location inference model. The core network element may forward only the inference model to the network element. The inference model may be used to determine the location of the user equipment, and the inference model may be deployed to the network element so that the network element can use it to determine and / or calculate the location of the user equipment. The determined and / or calculated location of the user equipment may be the initial location of the user equipment or an updated and / or revised location of the user equipment. In some embodiments, the location of the user equipment determined by the network element may be the absolute location of the user equipment (e.g., actual geographic coordinates) or the relative location of the user equipment with respect to the core network element or the nearest network element.

[0092] As an example, the network element 101 can determine and / or calculate the location of the user device 103 based on a ranging result report received from the user device 103 and a forwarded inference model deployed in a sub-LMF included in the network element 101.

[0093] At operation 735, the network element may transmit the location of the user device determined by the network element to a core network element. The location of the user device may be based on the inference model and the ranging result report. In some embodiments, the network element may broadcast the location of the user device determined by the network element to the telecommunications network as needed.

[0094] Referring now to FIG. 8, as shown in FIG. 8, a telecommunications network 800 may include a network element 101, a core network element 405, a regional network element 401, a user premises equipment 104, and a user device 103.

[0095] In an embodiment, the LMF may be included in a core network element. However, the LMF may be configured only to train the location inference model based on data generated throughout the telecommunications network. Thus, the core network element may only include the model-training phase of the location inference model. The core network may generate an inference model based on the machine-learned location inference model trained by the LMF. The core network element may transmit the inference model to lower-layer nodes in the telecommunications network 600. Moving the generated inference model to lower layers may reduce positioning latency and network traffic load for collecting information for training. As an example, the core network element may transmit the inference model to a user equipment (UE) whose location is being determined in the telecommunications network 600.

[0096] In some embodiments, the user equipment can generate a ranging result report, and the user equipment can calculate its own position using the ranging result report and the transferred inference model.

[0097] As an example, the core network element 405 can transmit the inference model to the sub-LMF of the user device 103, and the user device 103 can apply the transferred inference model only to determine its own location without training it. Since the inference model can be located in the sub-LMF of the user device 103, the user device 103 can determine its own location based on the transferred inference model. In some embodiments, the user device 103 can determine its own location based on its own ranging result report.

[0098] An example workflow 900 for determining the location of a user equipment is shown in FIG. 9, where the LMF may be located in a core network element, but the user equipment calculates the location of the user equipment.

[0099] As seen in FIG. 9, workflow process 900 may show one or more operations for determining the location of a user equipment when the LMF may be located in a core network element and the user equipment calculates its own location.

[0100] Operations 905 to 915 of the workflow process 900 are similar to operations 505 to 515 of the workflow process 500 and operations 705 to 715 of the workflow process 700 .

[0101] At operation 920, the user equipment may generate a ranging result report based on the SLRS. In some embodiments, the ranging result report may include one or more distance calculations between the user equipment and the user premises equipment based on the SLRS. The ranging result report may include correlated positioning reference signal information, where the correlated positioning reference signal information may include information associated with a positioning reference signal having a first transaction ID that is the same as a second transaction ID associated with the sidelink reference signal. In some embodiments, the first transaction ID and the second transaction ID are associated with the same position measurement time or the same user device. In some embodiments, the ranging result report may include Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or beam information associated with the received SLRS. The RSRP, RSSI, RSRO, and / or beam index may be used to measure the distance or directionality between the user equipment and the user premises equipment.

[0102] At operation 920, in some embodiments, the ranging result report generated by the user equipment may include a determination and / or calculation of its own (user equipment's) location based on the ranging result report and the forwarded inference model, where the forwarded inference model is based on a machine-learned location inference model. According to some embodiments of the present disclosure, a Location Management Function (LMF) may be located in a core network element and configured to train the location inference model. However, the LMF may be configured to generate the inference model based on the machine-learned location inference model. The core network element may forward only the inference model to the user equipment. The inference model may be used to determine the user equipment's location, and the inference model may be deployed to the user equipment, so that the user equipment determines its (user equipment's) location using the ranging result report and the inference model.

[0103] The determined and / or calculated position of the user equipment may be the initial position of the user equipment or an updated and / or revised position of the user equipment. In some embodiments, the position and / or location of the user equipment determined by the user equipment may be the absolute position (e.g., geographic coordinates) of the user equipment or the relative position of the user equipment with respect to a core network element or the nearest network element.

[0104] As an example, the user device 103 can generate a ranging result report for itself (the user device) and can determine and / or calculate its own location based on the ranging result report that the user device 103 generated itself and a transferred inference model based on the trained location inference model.

[0105] The user equipment may transmit its determined location across a telecommunications network as needed at operation 955. By way of example, the user device 103 may transmit its determined location across a telecommunications network as needed.

[0106] FIG. 10 is an example flowchart illustrating an example process 1000 for determining a location of a user device in a telecommunications network, according to an embodiment of the present disclosure.

[0107] According to an embodiment, operation 1010 may include transmitting, by a network element of the telecommunications network, a positioning trigger signal and a positioning reference signal to the user device. In some embodiments, the positioning trigger signal may be transmitted by the network element upon receiving an initial trigger signal from a core network element of the telecommunications network.

[0108] According to an embodiment, operation 1015 may include transmitting, by the user premises equipment, a sidelink reference signal to the user device. Any known format or protocol may be used to generate and configure the sidelink reference signal.

[0109] According to an embodiment, operation 1020 may include receiving, by a network element, a ranging result report. The ranging result report may be calculated by the user device. The ranging result report may include distance and timing information associated with signals received by the user device. In some embodiments, the ranging result report may be calculated by the user device and may include a calculation of a distance between the user device and user premises equipment based on information from the sidelink reference signal and the correlated positioning reference signal.

[0110] The correlated positioning reference signal information may include information associated with a positioning reference signal having a first transaction ID that is the same as a second transaction ID associated with the sidelink reference signal. In some embodiments, the first transaction ID and the second transaction ID may be associated with a position measurement time or a user device. According to embodiments, the ranging result report may include one or more of the following: a time lag between transmission and reception of the sidelink reference signal between the user device and the user premises equipment, position information related to the user premises equipment, power information related to the user device, power information related to the user premises equipment, an arrival time of the sidelink reference signal, or angle information related to reception of the sidelink reference signal. According to embodiments of the present disclosure, the ranging result report may also include signal information related to the positioning reference signal. The signal information may include at least one of sequence ID information related to the positioning reference signal and a beam index received by the user device related to the positioning reference signal.

[0111] According to an embodiment, operation 1025 may include transmitting, by the network element, a location of the user device to a core network element of the telecommunications network, where the location of the user device may be based on the machine-learned location inference model and the ranging result report. According to an embodiment, the machine-learned location inference model may be trained using a location management function, which may be part of the core network element.

[0112] In some embodiments, the inference model can be based on a machine-learned location inference model and can be sent to a sub-location management function of the network element, and the location of the user device can be calculated by the network element based on the inference model and the ranging result report. In some other embodiments, the inference model based on the machine-learned location inference model can be sent to a sub-location management function of the user device, and the location of the user device can be calculated by the user device based on the inference model and the ranging result report, and the ranging result report can be calculated by the user device and can further include the location of the user device.
