Description

location as a service

The case relates generally to wireless communications and technologies and devices used to provide location-as-a-service.

Wireless communication systems are widely deployed to provide various telecommunications services such as telephony, video, data, messaging and broadcasting. A typical wireless communication system may employ multiple access technology that can support communication with multiple users by sharing available system resources (eg, bandwidth, transmission power, etc.). Examples of such multiplexing techniques include code division multiplexing (CDMA) systems, time division multiplexing (TDMA) systems, frequency division multiplexing (FDMA) systems, orthogonal frequency division multiplexing (OFDMA) system, Single Carrier Frequency Division Multiplex Access (SC-FDMA) system, Time Division Synchronous Code Division Multiplex Access (TD-SCDMA) system and Long Term Evolution (LTE). LTE/LTE-Advanced (LTE-Advanced) is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile service standard promulgated by the 3rd Generation Partnership Project (3GPP).

A wireless network may include one or more base stations that support communications for one or more user equipment (UE). The UE may communicate with the base station via downlink communication and uplink communication. "Downlink" (or "DL") refers to the communication link from the base station to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the base station.

The multiple access technology described above has been adopted by various telecommunications standards to provide a common protocol that enables different UEs to communicate at city, country, regional and/or global levels. New Radio (NR), known as 5G, is a set of enhancements to the LTE mobile service standard promulgated by 3GPP. NR is intended to achieve this by increasing spectral efficiency, reducing costs, improving services, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink and on the uplink. CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)), and support beamforming, multiple-input multiple-output (MIMO) antennas technology and carrier aggregation are better integrated with other open standards to better support mobile broadband Internet access. As demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful.

Depending on the context in which the term is used, the term "cell" may represent a base station or AP 110, a coverage area of an access point, and/or a base station subsystem serving the coverage area.

A base station or AP 110 may provide communication coverage for macrocells, picocells, femtocells, and/or another type of cell. Macro cells can cover a relatively large geographical area (eg, a radius of several kilometers) and can allow unrestricted access by UEs or STAs 120 with service subscriptions. Pico cells may cover a relatively small geographical area and may allow unrestricted access by UEs or STAs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (eg, a home) and may allow restricted access of UEs or STAs 120 associated with the femto cell (eg, UEs or STAs 120 in a Closed Subscriber Group (CSG)) access. The base station 110 for a macro cell may be referred to as a macro base station. The base station 110 for a pico cell may be referred to as a pico base station. A base station or AP 110 for a femto cell may be referred to as a femto base station or home base station.

For example, in some aspects, "base station" or "network node" may refer to central unit (CU), distributed unit (DU), radio unit (RU), near-real-time (Near-RT) RAN smart controller ( RIC), or non-real-time (Non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may represent a device configured to perform one or more functions, such as those described herein in connection with base station or AP 110. In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of many different devices (which may be located in the same geographical location or at different geographical locations) may be configured to perform at least a portion of the functionality, or to replicate the performance of at least a portion of the functionality, and the term " "Base Station" or "Network Node" may refer to any one or more of these different devices. In some aspects, the terms "base station" or "network node" may represent one or more virtual base stations and/or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be physically present on a single device.

Generally, any number of wireless networks 100 can be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT can be called radio technology, air interface, etc. Frequencies can be called carriers, frequency channels, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some examples, two or more UEs or STAs 120 (e.g., shown as UE or STA 120a and UE or STA 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 act as an intermediary in communicating with each other). For example, the UE or STA 120 may use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (eg, which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) ) protocol or vehicle-to-pedestrian (V2P) protocol) and/or mesh networks to communicate. In such instances, UE or STA 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by base station or AP 110.

Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various categories, frequency bands, channels, etc. For example, devices of wireless network 100 may communicate using one or more operating frequency bands. In 5G NR, the two initial operating frequency bands have been identified as frequency range names FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles, although a portion of FR1 is greater than 6 GHz. Similar naming issues sometimes arise with FR2, although FR2 is not the same as the extremely high frequency (EHF) band (30 GHz–300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" band, but in documents and articles Often referred to (interchangeably) as the "millimeter wave" frequency band.

The frequencies between FR1 and FR2 are often called mid-band frequencies. Recent 5G NR studies have identified the operating band of these mid-band frequencies as the frequency range designation FR3 (7.125 GHz–24.25 GHz). Frequency bands falling within FR3 can inherit FR1 characteristics and/or FR2 characteristics, thus effectively extending the characteristics of FR1 and/or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operations beyond 52.6 GHz. For example, the three higher operating bands have been identified with the frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

With the above examples in mind, unless expressly stated otherwise, it should be understood that the terms "sub-6 GHz" and the like, if used herein, can broadly mean frequencies that may be less than 6 GHz, frequencies that may be within FR1, or that may include mid-band frequencies frequency. Additionally, unless otherwise specifically stated, it will be understood that the terms "millimeter wave" and the like, if used herein, may broadly refer to frequencies that may include mid-band frequencies, which may be in the FR2, FR4, FR4-a, or FR4-1 and / Or frequencies within FR5, or possibly within the EHF band. It is contemplated that frequencies included in such operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges .

In some aspects, base station 110 may include a communications manager 140.

FIG. 3 is a schematic diagram illustrating an exploded base station architecture according to an example 300 of the present application.

The deployment of communication systems, such as 5G NR systems, can be arranged in a variety of ways with various elements or components. In a 5G NR system or network, a network node, network entity, mobile element of the network, RAN node, core network node, network element or network equipment, such as a base station (BS, e.g., base station 110 ), or one or more units (or one or more elements) that perform the functions of a base station, may be implemented in a converged or disaggregated architecture. For example, a BS (such as a Node B (NB), eNB, NR BS, 5G NB, AP, TRP, cell, etc.) may be implemented as an aggregated base station (also known as a standalone BS or monolithic BS) or as a disaggregated base station.

Aggregated base stations may be configured to utilize radio protocol stacks that are physically or logically integrated within a single RAN node. A disaggregated base station may be configured to utilize data between two or more units, such as one or more central or centralized units (CU), one or more decentralized units (DU), or one or more radio units (RU). ) between entities or logical distribution agreement stacking. In some aspects, a CU may be implemented within a RAN node and one or more DUs may be co-located with the CU or, alternatively, may be geographically or virtually distributed among one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU and RU may also be implemented as a virtual unit, namely a Virtual Centralized Unit (VCU), a Virtual Distributed Unit (VDU) or a Virtual Radio Unit (VRU).

Base station type operations or network design can take into account the aggregated nature of base station functionality. For example, disaggregated base stations can be used for integrated access backhaul (IAB) networks, O-RAN (network configurations such as those initiated by the O-RAN Alliance) or virtualized radio access networks (vRAN, also known as cloud radio access networks). Take the network (C-RAN)). Disaggregation may include allocating functionality across two or more units at different physical locations, as well as virtually allocating functionality to at least one unit, which allows for flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

The disaggregated base station architecture shown in Figure 3 may include one or more CUs 310, which may communicate directly with the core network 320 via a backhaul link, or via one or more disaggregated base station units (such as via an E2 link road's near-real-time (Near-RT) RAN Intelligence Controller (RIC) 325, or non-real-time (Non-RT) RIC 315 associated with the Service Management and Orchestration (SMO) framework 305, or both) indirectly with the core Network 320 Communications. CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link, such as an F1 interface. DU 330 may communicate with one or more RUs 340 via corresponding fronthaul links. RU 340 may communicate with corresponding UE or STA 120 via one or more radio frequency (RF) access links. In some implementations, a UE or STA 120 may be served by multiple RUs 340 simultaneously.

Each of the units (eg, CU 310, DU 330, RU 340) and Near-RT RIC 325, Non-RT RIC 315, and SMO framework 305 may include one or more interfaces or coupled to one or more interfaces configured to receive or transmit signals, data or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller that provides instructions to the unit's communication interface, may be configured to communicate with one or more other units via the transmission medium. For example, a unit may include a wired interface configured to receive or transmit signals to one or more other units via a wired transmission medium. Additionally, the units may include a wireless interface, which may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals via a wireless transmission medium or to transmit signals to one or more other units, Or both.

In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to communicate signals with other control functions hosted by the CU 310. CU 310 may be configured to handle user plane functions (eg, Central Unit-User Plane (CU-UP)), control plane functions (eg, Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, CU 310 may be logically separated into one or more CU-UP units and one or more CU-CP units. The CU-UP unit may communicate bi-directionally with the CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 can be implemented to communicate with the DU 330 for network control and signal transmission when necessary.

DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340 . In some aspects, DU 330 may host a radio link control (RLC) layer, a media access control (MAC) layer, and one or more physical high (PHY) layers (such as for forward error correction (FEC) coding and one or more of the modules for decoding, scrambling, modulation and demodulation, etc.), depending at least in part on their separation of functions such as those defined by 3GPP. In some aspects, the DU 330 can further host one or more lower PHY layers. Each layer (or module) may be implemented with an interface configured to communicate signals with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

Lower layer functions may be implemented by one or more RUs 340. In some deployments, RU 340 controlled by DU 330 may be based, at least in part, on functional separation such as lower layer functional separation corresponding to hosted RF processing functions or low PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or logical nodes for both. In such an architecture, RU(s) 340 may be implemented to handle over-the-air (OTA) communications with one or more UEs or STAs 120. In some embodiments, the real-time and non-real-time aspects of control plane communication and user plane communication with the RU(s) 340 may be controlled by the corresponding DU 330. In some scenarios, such a configuration may enable the DU(s) 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support deployment of dedicated physical resources for RAN coverage requirements that may be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform, such as an Open Cloud (O-Cloud) 390, to perform network element lifecycle management (such as Generate physical virtual network elements). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, and Near-RT RIC 325. In some embodiments, the SMO framework 305 may communicate with hardware aspects of the 4G RAN, such as enabling eNB (O-eNB) 311 via the O1 interface. Additionally, in some implementations, the SMO framework 305 may communicate directly with one or more RUs 340 via the O1 interface. The SMO framework 305 may also include a Non-RT RIC 315 configured to support the functionality of the SMO framework 305 .

Non-RT RIC 315 can be configured to include logic functionality that supports non-real-time control and optimization of RAN elements and resources, artificial intelligence/machine learning (AI/ML) workflows (including model training and updates), or Policy-based guidance on applications/features in Near-RT RIC 325. Non-RT RIC 315 may couple to or communicate with Near-RT RIC 325 (such as via the A1 interface). Near-RT RIC 325 may be configured to include logic functionality via an interface that connects one or more CUs 310, one or more DUs 330, or both, such as via an E2 interface, and with the Near-RT RIC Data collection and actions on 325's O-eNB enable near-real-time control and optimization of RAN elements and resources.

In some embodiments, to generate AI/ML models to be deployed in Near-RT RIC 325, Non-RT RIC 315 may receive parameters or external rich information from an external server. Such information may be utilized by Near-RT RIC 325 and may be received at SMO framework 305 or Non-RT RIC 315 from non-network sources or from network functions. In some examples, Non-RT RIC 315 or Near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, Non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI/ML models to perform corrective actions via SMO framework 305 (such as via O1 reconfiguration) or via establishing RAN management policies (such as as A1 policies).

As stated previously, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3.

Typically, over-the-air (OTA) decisions (eg, location protocol selection, protocol parameter selection, location channel scheduling or transmission opportunity (TXOP) management, etc.) are implemented in hardware and/or firmware. Implementing OTA decisions in hardware and/or firmware enables real-time decisions related to channel selection and/or optimized service objectives within the window of a TXOP or frame exchange sequence.

However, implementing OTA decisions in hardware and/or firmware may prevent decisions based on various conditions and/or considerations such as network queue status, peer device capabilities, use case-related performance goals, and/or service provider specifications. coordinated location ranging across multiple access points, etc.) to make OTA decisions.

This article describes some of the techniques and devices that enable network nodes to provide location as a service. In some aspects, as described in greater detail elsewhere herein, a layered communication loop may be implemented within a wireless network. The first communication loop may include communication between a central controller device (eg, a network node acting as a central controller device within the network) and a resource management element of the network node. The first communication loop may include a slow loop involving communication of intent via decision boundary knobs, peer device turnaround time estimates (across multiple APs), multi-channel splicing, location network resource allocation, location tracking and navigation, and/or Advanced telemetry from cloud-based controllers leads to machine learning-driven inference. The second communication loop may include communication between the resource management element and the firmware layer of the network node. The second communication loop may include a medium speed loop involving algorithms acting on telemetry and slow loop decision boundaries, MAC address spoofing, channel scanning, location protocol selection, and/or parameter selection. The third communication loop may include communication between a firmware layer of the network node and a hardware layer of the network node. The third communication loop may include a fast loop involving ultra-fast execution loops for transmission opportunity resolution, position frame transmission and reception, timestamp estimation, timing correction, and/or space diversity ranging. Accordingly, the central controller device may communicate OTA decisions to the network nodes via the first communication loop that are based at least in part on an overall view of the current conditions of the network, specific use case performance goals, and/or capabilities of the devices included in the network, while utilizing Embodiments are enabled by speed associated with communication occurring via a third communication loop (eg, via firmware and/or hardware layers).

A layered control loop enables location delivery as a software service (end-to-end). The hierarchical control loop can provide a framework for fast loop innovations such as improved accuracy via advanced signal processing algorithms, switching diversity ranging, and higher channel bandwidth operation. The framework that exists in the middle loop supports coordinated ranging across AP bands within a single AP (appearing to ranging devices as requests from the same physical AP). The framework for slow loops may involve turnaround time estimation (for one-sided RTT), which may be accomplished by triangulating multiple APs and/or coordinating AP ranging.

In some aspects, slow loops can use location network resource allocation (which APs are ranged to which STAs at what time and order), peer turnaround time estimation, and/or location tracking and navigation. The middle loop may use MAC address spoofing, channel changes, location protocol selection (e.g., one-sided RTT, Quality of Service (QoS) null scheduling), and/or protocol parameter selection (e.g., number of frames per burst, time gap between boxes). The fast loop may change to an STA channel, transmit QoS empty frames with spoofed MAC addresses, receive acknowledgments (ACKs), and/or capture and report departure and arrival times.

Figure 4 is a schematic diagram illustrating an instance 400 associated with providing location as a service according to the present case. As shown in Figure 4, the instance 400 includes a plurality of network nodes (eg, a first network node 401, a second network node 402, and a third network node 403, as shown) and a UE 404 (eg, a UE or STA 120). In some aspects, a plurality of network nodes and UEs or STAs 120 may be included in a wireless network, such as wireless network 100. In some aspects, one or more of the plurality of network nodes may include a wireless access point, base station or AP 110, and/or one or more elements of base station 110 (e.g., DU, CU and/or TRP).

As shown by element symbol 405, the first network node 401 can receive device information and/or network information from the network node. Device information received from a network node may indicate one or more capabilities of the network node. For example, the device information received from the second network node may indicate the location ranging technology associated with the second network node (e.g., one-sided RTT, dual-side RTT based on Institute of Electrical and Electronics Engineers (IEEE) 802.11mc fine timing measurements. side RTT, single user (SU) ranging based on IEEE 802.11az non-triggering, multi-user (MU) ranging based on IEEE 802.11az triggering and/or ranging based on IEEE 802.11az passive triggering, etc.).

In some implementations, network information received from a network node may include information indicating network conditions. For example, the network information received from the second network node 402 may indicate the single quality of the channel, the amount of bandwidth currently used, the data transfer rate, the signal to interference plus noise ratio (SINR), and/or the communication with the second network node 402 . The number of UEs associated with path node 402, and so on.

In some aspects, the first network node 401 may receive device and/or network information from one or more UEs associated with the wireless network (eg, UEs connected to the network node). For example, UE 404 may be connected to a network node (eg, third network node 403). The UE 404 may provide the first network node 401, directly or indirectly (eg, via a third network node 403), an indication of one or more capabilities of the UE 404, one or more services requested by the UE 404 (eg, location). service) and/or one or more device and/or network characteristics associated with UE 404. For example, UE 404 may provide maximum bandwidth, signal quality, and/or location ranging associated with UE 404 to a first network node based at least in part on connecting to a network node (eg, via third network node 403) Technical instructions, etc.

In some aspects, the first network node 401 may decide to provide location services to the UE 404 based at least in part on device information and/or network information. For example, the device information received from the UE 404 may include a request for location services, and the first network node 401 may decide to provide location services to the UE 404 based at least in part on the request. Additionally or alternatively, the first network node 401 may receive an indication from another device (eg, the third network node 403) that location services are to be provided to the UE 404.

As shown by element 410, the first network node 401 may determine location network resource allocation associated with providing location services to the UE 404. In some aspects, location network resource allocation may include location ranging techniques for providing location services to UE 404.

In some aspects, location network resource allocation may include a set of one or more network nodes to perform one-sided RTT. In some aspects, the first network node 401 may determine the network node group based at least in part on device information and/or network information received from network nodes included in the network. For example, the first network node 401 may be based at least in part on whether the network node is associated with single-sided RTT capabilities, whether the traffic associated with the network node meets a threshold, the number of UEs associated with the network node, The network node is determined by whether the UE 404 is associated with a network node, and/or the location of the network node relative to the location of the network node with which the UE 404 is associated (eg, the third network node 403 ), etc. group.

In some aspects, the location network resource allocation may include the time for each network node included in the group of network nodes to perform a one-sided RTT. For example, the location network resource allocation may indicate the time of day, transmission slot, and/or time period after an event occurs (eg, receipt of a message from a first network node), etc.

In some aspects, location network resource allocation may include the order in which groups of network nodes perform one-sided RTT. For example, the location network resource allocation may indicate that the third network node 403 will be the first to perform the one-sided RTT procedure and/or the second network node 402 will be the second to perform the one-sided RTT procedure.

In some aspects, the first network node 401 may generate single-sided RTT configuration information based at least in part on location network resource allocation.

In some aspects, the one-sided RTT configuration information may include mobility information associated with UE 404. For example, the first network node 401 may determine the speed and/or direction of movement associated with the UE 404 based at least in part on information received from network nodes included in the network.

In some aspects, the single-sided RTT configuration data may indicate the MAC address of a network node associated with UE 404 (eg, third network node 403). The MAC address may be included in messages transmitted during the one-sided RTT procedure (e.g., frames, data packets, and/or another type of communication) to enable the UE 404 to determine that the message was sent by the network node associated with the UE 404 Transmitted to UE 404 as described in greater detail elsewhere herein.

In some aspects, the one-sided RTT configuration data may indicate sequence numbers to be included in messages transmitted during the one-sided RTT procedure. For example, the first network node 401 may determine the last or closest sequence number to the UE 404 used by the network. The one-sided RTT configuration data may include an indication of the sequence number and/or an indication of the next sequence number (eg, the first one) to be utilized by the network node that will next perform the one-sided RTT procedure.

In some aspects, the first network node 401 may transmit an indication of the most recent sequence number or the next sequence number to the network node based at least in part on which network node is next in sequence to perform the one-sided RTT procedure. As an example, the first network node 401 may determine that the first network node 401 (eg, the third network node 403) has performed a one-sided RTT procedure with the UE 404. The first network node 401 can determine the nearest sequence number (eg, the sequence number used by the third network node 403 to perform the one-sided RTT procedure) and can proceed to the next network node to perform the one-sided RTT procedure (eg, the second The network node) transmits the indication of the sequence number and/or the indication of the next sequence number. In this way, the first network node 401 can maintain the monotonicity of the sequence number. Maintaining monotonicity of sequence numbers may prevent interoperability issues associated with UE 404 receiving a message that includes a sequence number that is different from the next sequence number.

As indicated by reference numeral 415, the first network node 401 may provide information to network nodes included in the network node group (eg, the second network node, the third network node 403, and one or more additional The network node (not shown) transmits the single-sided RTT configuration data. In some aspects, the one-sided RTT may be transmitted via the first communication loop in a set of hierarchical communication loops implemented in the network.

In some aspects, the first communication loop may include communications transmitted between the first network node 401 (eg, a central controller device) and the network node's resource manager element. For example, the first network node 401 may transmit the single-sided RTT configuration data to the second network node 402 via a first communication loop including resource management elements of the first network node 401 and the second network node 402 . Similarly, the first network node 401 may transmit the single-sided RTT configuration data to the third network node 403 via the first communication loop including the resource management elements of the first network node 401 and the third network node 403 .

In some aspects, the resource management element may determine the sequence number to include in the message transmitted to UE 404. For example, the single-sided RTT configuration data may indicate the closest sequence number to UE 404 utilized by the network. The resource management element may increment the most recent sequence number to generate the sequence number to be included in the message transmitted to UE 404.

The resource management element may transmit an indication of one or more parameters to the firmware layer of the third network node 403 . In some aspects, one or more parameters are transmitted via a second communication loop including the resource management element and the firmware layer of the third network node 403 .

In some aspects, one or more parameters associated with performing the one-sided RTT procedure may be transmitted via a third communication loop such that the one-sided RTT procedure may be performed based on the one or more parameters.

For example, the hardware layer may transmit data associated with the transmission message to the firmware layer via the third communication loop. The firmware layer may generate and/or record data indicating the time of day of the transmitted message and/or a timestamp associated with the transmitted message.

As shown at element 425, the UE 404 may transmit an ACK based at least in part on receiving the message from the third network node 403, and the third network device 403 may receive the ACK. The third network node 403 may record additional time information associated with receiving the ACK from the UE 404. For example, the hardware layer may transmit the ACK to the firmware layer via the third communication loop. The firmware layer may generate and/or record additional time data indicating the time of day when the ACK was received and/or a timestamp associated with receiving the ACK from the UE 404.

In some aspects, the firmware layer may transmit time data and/or additional data to the resource management component via the second communication loop.

In some aspects, the resource management element may determine one or more parameters in a manner similar to that described above with respect to third network node 403.

In some aspects, the resource management element may determine whether MAC address spoofing was performed based at least in part on the MAC address indicated in the single-sided RTT configuration information. For example, the resource management component may determine that the single-sided RTT configuration data indicates a MAC address rather than the MAC address associated with the second network node 402 . The resource management element may determine that MAC address spoofing will be performed based at least in part on the MAC address indicated by the single-sided RTT configuration data rather than the MAC address associated with the second network node 402 .

In some aspects, the resource management element may determine the sequence number to include in the message transmitted to UE 404. For example, the resource management element may receive from the first network node 401 an indication of the last sequence number used by the second network node 402. The resource management element may increment the last sequence number to generate the sequence number to be included in the message transmitted to UE 404.

The resource management element may transmit an indication of one or more parameters to the firmware layer of the second network node 402 . In some aspects, one or more parameters are transmitted via a second communication loop including the resource management element and the firmware layer of the second network node 402 .

In some aspects, one or more parameters associated with performing the one-sided RTT procedure may be transmitted via a third communication loop such that the one-sided RTT procedure may be performed based on the one or more parameters. In some aspects, the third communication loop may include a firmware layer and a hardware layer of the second network node 402 . In some aspects, transmitting one or more communications via a third communications loop enables the hardware layer to perform a one-sided RTT procedure.

As shown by element 435, the second network node 402 may transmit a message to the UE 404. In some aspects, the message may include QoS null messages. In some aspects, the second network node 402 may perform MAC address spoofing, and the message may indicate that the message was transmitted to the UE 404 by the third network node 403 (eg, the network node associated with the UE 404). In some aspects, the message may include a sequence number generated by the resource management component.

In some aspects, the second network node 402 may record timing data associated with transmitting the message to the UE 404. For example, the hardware layer may transmit data associated with transmitting messages to the firmware layer via a third communication loop. The firmware layer may generate and/or record time data indicating the time of day when the message was transmitted and/or a timestamp associated with the transmitted message.

As shown by element 440, the UE 404 may transmit an ACK based at least in part on receiving the message from the second network node 402. In some aspects, the UE 404 may transmit an ACK based at least in part on the message indicating that the message was transmitted to the UE 404 by the third network node 403. In some aspects, the second network node 402 may monitor messages transmitted to the third network node 403 based at least in part on performing address spoofing using the MAC address of the third network node 403 . The second network node 402 may receive the ACK based at least in part on monitoring the message transmitted to the third network node 403 .

The second network node 402 may record additional time data associated with receiving the ACK. For example, the hardware layer may transmit the ACK to the firmware layer via the third communication loop. The firmware layer may generate and/or record additional time data indicating the time of day when the ACK was received and/or a timestamp associated with receiving the ACK.

In some aspects, the firmware layer may transmit time data and/or additional data to the resource management component via the second communication loop. The resource management element may generate the one-sided RTT data based at least in part on the time data and/or the additional time data. In some aspects, the one-sided RTT data may indicate the last sequence number utilized by the second network node with the UE.

As indicated by element 445, the second network node 402 may transmit the one-sided RTT data based at least in part on executing the one-sided RTT procedure, and the first network node 401 may receive the one-sided RTT data. In some aspects, the one-sided RTT data can be transmitted to the first network node via the first communication loop.

In some aspects, the first network node 401 can determine the next sequence number and can transmit the next sequence number to the network node that next performs the one-sided RTT procedure. For example, the one-sided RTT information received from the second network node 402 may include the last sequence number utilized by the second network node 402 with the UE 404 . The first network node 401 may determine, based at least in part on the order in which the network node group performs the one-sided RTT procedure, that the fourth network node (not shown) should perform the one-sided RTT procedure next. The first network node 401 may transmit to the fourth network node an indication of the last sequence number utilized by the second network node 402 with the UE 404 .

In some aspects, each network node included in the network node group may perform a one-sided RTT procedure with the UE 404 and may transmit the one-sided RTT data to the first network node 401 in a manner similar to that described above. . The first network node 401 may decide to receive one-sided RTT data from each network node included in the network node group, and as shown by element 450 , the first network node 401 may be based at least in part on receiving the single-sided RTT data from the network node. The one-sided RTT data received by the road node group is used to determine the location data of UE 404.

As an example, the first network node 401 may determine a first time and corresponding time corresponding to the time when the third network node 403 transmits the message to the UE 404 based at least in part on the one-sided RTT data received from the third network node 403 At a second time when the third network node 403 receives the ACK from the UE 404 . The first network node 401 may decide a value corresponding to the difference between the first time and the second time. The first network node 401 may decide that this value corresponds to the round trip time (eg, the amount of time for the message to propagate from the third network node 403 to the UE 404 plus the amount of time for the ACK to propagate from the UE 404 to the third network node 403) Add turnaround time (eg, the amount of time from when UE 404 receives the message to when UE 404 transmits an ACK).

The first network node 401 may determine a corresponding value for each network node included in the network node group. The first network node 401 may utilize the determined value to determine an estimated turnaround time associated with the UE 404 . The first network node 401 may determine the location profile of the UE 404 based at least in part on the estimated turnaround time.

In some aspects, the first network node 401 can provide location information to the UE 404. For example, the first network node 401 can transmit the location data to the third network node 403 and the third network node 403 can forward the location data to the UE 404 .

Network nodes (eg, APs) are controlled by a central controller and may be arranged in close temporal proximity to STAs. A STA may have an unknown turnaround time, which can be estimated by solving an equation formed by multiple APs, as well as the unknown coordinates of the STA. One-sided RTT achieves accurate ranging performance in enterprise positioning use cases, and the performance can be much better than RSSI-based ranging. However, network nodes (e.g., APs) cannot perform one-sided RTT with unassociated clients (with limited performance). By using a location controller (slow loop) to notify all APs requiring location (medium loop) to send messages (e.g., QoS empty frames) to STAs by spoofing the MAC address of the frame to that of the associated AP, The STA does not reject messages because messages from other APs appear to come from the associated AP. When spoofing MAC addresses, the AP network may need to maintain sequence number (SN) monotonicity to prevent interoperability issues. This can be accomplished by the AP network instructing the AP network via the AP controller the last SN used by the peer device, so that the next spoofing AP can increase the SN in the spoofing QoS air frame to maintain the monotonicity of the SN. Although QoS null frames are discussed in the example, sequence numbers are appropriately maintained within the AP network, but the approach described in this article can be generalized to other frames, not just QoS null frames. In some aspects, the second network node 402 and/or the third network node 403 may estimate the angle of arrival (AoA) data of the ACK and transmit the AoA data to the first network node 401 . The angle of arrival of the ACK received by the network node may indicate the relative angle of the UE 404 to the network node. The first network node 401 may further determine the location of the UE 404 based at least in part on determining the location of the UE 404 . If both the one-sided RTT data and the angle of arrival data are available, the first network node 401 can combine the one-sided RTT data and the angle of arrival data to further improve positioning performance or reduce the number of APs required to derive the location of the UE 404. Alternatively, in some aspects, the first network node 401 may only use angle of arrival data to locate the UE 404.

Single-sided RTT data may involve the AP sending a QoS airframe, retrieving the departure time, receiving an ACK, retrieving the arrival time, and then estimating the single-sided RTT. In contrast, angle of arrival data does not require the AP to send any signals or messages. The AP may only receive an ACK, which is sufficient to estimate the angle of arrival of the ACK. That is, a network controller might request a large number of APs to enter the same channel at approximately the same time, and only have one of them send a QoS null frame (using a spoofed MAC address if that AP is not the associated AP). All APs may then listen for ACKs from UE 404 and use the same ACK to estimate the angle of arrival to locate UE 404. As such, the first network node 401 may not care about sending multiple QoS null frames and taking too long with the risk that the UE 404 has changed location.

As mentioned previously, Figure 4 is provided as an example. Other examples may differ from what is described with respect to Figure 4.

Figure 5 is a schematic diagram illustrating an instance 500 associated with providing location as a service according to the present case.

In some aspects, first network node 501, second network node 502, and UE 503 may be included in a wireless network, such as wireless network 100. In some aspects, the first network node 501 and/or the second network node 502 may include a wireless access point, the base station 110 and/or one or more elements of the base station 110 (eg, DU, CU and/or or TRP).

As shown in FIG. 5 , the first network node 501 may be configured as a central controller device for a wireless network including a plurality of network nodes including the second network node 502 . As shown by element 505, the first network node 501 may receive device information and/or network information from a plurality of network nodes (eg, from the second network node 502, as shown). In some aspects, the first network node 501 may receive device information and/or network information in a manner similar to that described above with respect to FIG. 4 .

In some aspects, the first network node 501 may receive device and/or network information from one or more UEs associated with the wireless network (eg, UEs connected to the network node).

The UE 503 may provide the first network node 501, directly or indirectly (eg, via the second network node 502), an indication of one or more capabilities of the UE 503, one or more services requested by the UE 503 (eg, location). services) and/or one or more device and/or network characteristics associated with UE 503 in a manner similar to that described above with respect to FIG. 4 .

In some aspects, the first network node 501 may decide to provide location services to the UE 503 based at least in part on device information and/or network information. For example, the device information received from the UE 503 may include a request for location services, and the first network node 501 may decide to provide location services to the UE 503 based at least in part on the request. Additionally or alternatively, the first network node 501 may receive an indication from another device (eg, the second network node 502) that location services are to be provided to the UE 503.

In some aspects, location network resource allocations may include frequency bands (e.g., 5 GHz band or 6 GHz band) and/or regions within frequency bands (e.g., 5 GHz lower bands of the 5 GHz band) for performing channel scans , Dynamic Frequency Selection (DFS) band and/or 5 GHz higher band). In some aspects, the first network node 501 may receive a channel status report from each of the plurality of network nodes. Channel status reports may indicate whether a channel associated with a network node is idle and/or busy, as well as other characteristics of the channel. The first network node 501 may determine a frequency band and/or a region within the frequency band for performing channel scanning based at least in part on channel status reports received from a plurality of network nodes.

In some aspects, the channel scanning procedure will be completed in a relatively short period of time (e.g., within 100 milliseconds) to ensure that the UE's position does not change by more than a distance corresponding to half a wavelength (e.g., approximately 3 cm) and/or enable the channel responses obtained by performing the channel scanning process to be considered coherent and spliced together. Because the first network node 501 receives channel status reports from a plurality of network nodes, the first network node 501 is able to select a frequency band and/or a region within the frequency band that is not busy (eg, less than a threshold traffic volume) and minimize Co-channel interference and/or adjacent channel interference.

In some aspects, the first network node 501 may generate channel scan configuration data based at least in part on location network resource allocation. For example, the first network node 501 may generate channel scan configuration data indicating a selected frequency band and/or a selected region within the frequency band.

In some aspects, the first network node 501 may scan the channel configuration data via a first communication loop including a resource management element of the first network node 501 (eg, a central controller device) and the second network node 502 transmitted to the second network node 502.

In some aspects, the resource management component of the second network node 502 may receive channel scan configuration data from the first network node 501 . The resource management component may determine to perform a channel scan procedure based at least in part on the channel scan configuration data.

For example, the resource management component may determine single or mixed scan bandwidth, the number of channels to be scanned, the time gap between frames, the resources to be used to perform the channel scan process, and/or the resources to be used as a channel scan process. Partially transmitted data is associated with priorities, etc.

The resource management element may transmit an indication of one or more parameters to the firmware layer of the second network node 502 .
