In the method, when the actual selected sample number Nt of continuous measurement of an access network device is inconsistent with the sample number Nt of continuous measurement configured by an LMF, the access network device can carry the actual selected sample number Nt of continuous measurement of the access network device in a measurement report. In this way, after the LMF learns that the actual selected sample number Nt of continuous measurement of the access network device is inconsistent with the sample number Nt of continuous measurement configured by the LMF, the LMF can take a preprocessing operation to avoid an increase in measurement error.

Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to a measurement configuration method, apparatus, and storage medium. Background Technology

[0002] In the field of wireless positioning, artificial intelligence (AI) and machine learning (ML) technologies have become important means to improve the accuracy of wireless positioning.

[0003] As a core network element of the control plane, the location management function (LMF) can be dynamically configured to use both sample-based measurement and path-based measurement modes. LMF supports inputting measurement data from a single measurement mode into the AI ​​model for training, or it can fuse measurement data from both measurement modes.

[0004] For sample-based measurement modes, if the number of continuous measurement samples Nt configured by the LMF is inconsistent with the number of continuous measurement samples Nt actually selected by the new radio access node (gNB) / transmission reception point (TRP), the LMF may misunderstand the current channel environment state, resulting in errors in its estimated multipath delay spread and angle spread, which will affect the training and inference performance of the AI ​​model. Summary of the Invention

[0005] This application provides a measurement configuration method, apparatus, and storage medium to solve the problem that the LMF misunderstands the current channel environment state due to the inconsistency between the number of continuous measurement samples Nt configured by the LMF and the number of continuous measurement samples Nt actually selected by the gNB / TRP, resulting in errors in its estimated multipath delay spread and angle spread.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] Firstly, a measurement configuration method is provided. This method can be executed by an access network device, or by a component (such as a circuit, chip, or chip system) configured in the access network device, or by a logic module or software capable of implementing all or part of the functions of the access network device. The access network device is also called an access node, such as a gNB or TRP. The following description uses an access network device as an example.

[0008] The method may include: an access network device receiving a measurement request message from an LMF, the measurement request message indicating the number of continuous measurement samples configured by the LMF and enabling condition-based continuous measurement sample number reporting; the access network device sending a measurement report message to the LMF, the measurement report message including measurement results and the number of continuous measurement samples actually selected by the access network device, the number of continuous measurement samples actually selected by the access network device being inconsistent with the number of continuous measurement samples configured by the LMF.

[0009] In the above scheme, the LMF enables condition-based continuous measurement sample number reporting through measurement request messages. This allows the access network device to include the actual number of continuous measurement samples Nt selected by the access network device in the measurement report when the conditions are met. In this way, the LMF can detect that the actual number of continuous measurement samples Nt selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF, thus more accurately estimating multipath delay spread and angle spread, avoiding increased measurement errors, and improving the inference performance of the AI ​​model.

[0010] In one possible implementation, the condition in "enabling condition-based continuous measurement sample number reporting" can be: the number of continuous measurement samples Nt actually selected by the access network device is less than the number of continuous measurement samples Nt configured by the LMF, or the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF. On one hand, the access network device can adjust its continuous measurement sample number, causing its selected Nt value to differ from the Nt value indicated by the LMF. When the actual number of measurement samples is insufficient, it will affect the sufficiency and accuracy of the channel measurement information. Therefore, the LMF instructs the access network device to enable condition-based continuous measurement sample number reporting through the measurement quantity request field, so that the access network device can report the actual selected Nt value to the LMF when its selected Nt value is less than the Nt value indicated by the LMF. On the other hand, the measurement duration is determined based on the number of continuous measurement samples, measurement granularity, and basic time unit. For example, the measurement duration can be determined according to the formula Nt·2. kThe value is calculated as ×Tc, where Nt represents the number of continuous measurement samples, k represents the measurement granularity, and Tc represents the basic time unit. Since the access network device can adjust its continuous measurement sample count Nt and measurement granularity k, when the actual number of continuous measurement samples Nt selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF, the actual measurement duration of the access network device will be less than the measurement duration indicated by the LMF. If the actual measurement duration is insufficient, it will also affect the sufficiency and accuracy of the channel measurement information. Therefore, the LMF instructs the access network device to enable conditional continuous measurement sample count reporting through the measurement quantity request field. This allows the access network device to report its actual selected Nt value to the LMF when its selected actual measurement duration is less than the measurement duration indicated by the LMF. It can be understood that regardless of which condition is used, the LMF will be aware that the actual Nt value selected by the access network device is inconsistent with the Nt value configured by the LMF.

[0011] In one possible implementation, the measurement request message may include a measurement quantity request field. This measurement quantity request field can be used to indicate whether condition-based continuous measurement sample count reporting is enabled. The measurement quantity request field is of Boolean type. If the measurement quantity request field is a first value (e.g., the first value is true), then the measurement quantity request field can be used to indicate whether condition-based continuous measurement sample count reporting is enabled; or, if the measurement quantity request field is a second value (e.g., the second value is false), then the measurement quantity request field can be used to indicate whether condition-based continuous measurement sample count reporting is disabled. It can be understood that adding a Boolean measurement quantity request field to the measurement request message is equivalent to setting an enable switch. By changing the value of the enable switch, the LMF can indicate to the access network device whether to report the actually selected Nt value.

[0012] In one possible implementation, before sending a measurement report message to the LMF, the method may further include: if the measurement quantity request field is a first value (e.g., the first value is true), determining that the number of continuous measurement samples actually selected by the access network device is less than the number of continuous measurement samples configured by the LMF, or that the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF. It is understood that when the enable switch is true, if the number of continuous measurement samples actually selected by the access network device is small, or the actual measurement duration is insufficient, it will affect the sufficiency and accuracy of the channel measurement information. By sending a measurement report message to the LMF, the access network device can inform the LMF that the number of continuous measurement samples Nt actually selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF.

[0013] In one possible implementation, the aforementioned measurement request message can also be used to indicate the measurement type, which is a sample-based measurement. It is understood that a sample-based measurement configuration requires a larger number of measurements compared to a path-based measurement configuration. When the LMF indicates that the measurement type is a sample-based measurement, if the Nt value actually selected by the access network device is inconsistent with the Nt value configured by the LMF, the access network device needs to provide the actually selected Nt value.

[0014] In one possible implementation, the aforementioned measurement request message can also be used to indicate the number of reported samples Nt' and the measurement granularity k configured by the LMF. Here, the number of reported samples Nt' refers to the Nt' time-domain channel response values ​​selected from Nt consecutively measured channel response values, ordered according to received power. It can be understood that by configuring the number of consecutively measured samples Nt, the number of reported samples Nt', and the measurement granularity k, the LMF enables access network equipment to measure the SRS signal based on these parameters, thereby obtaining measurement results containing multipath information.

[0015] In one possible implementation, the method may further include: receiving a measurement request message resent by the LMF, wherein the resent measurement request message includes at least one of the following: the updated measurement type, the updated number of samples for continuous measurements, the updated number of samples for the report, and the updated measurement granularity. It can be understood that by updating the measurement configuration of the first group, the current measurement configuration can be adapted to the AI ​​positioning requirements, improving measurement reporting efficiency.

[0016] Secondly, a measurement configuration method is provided. This method can be executed by an LMF (Limited Flow Mechanism), or by a component configured in the LMF (such as a circuit, chip, or chip system), or by a logic module or software capable of implementing all or part of the LMF's functions. This application does not limit the scope of this method. The following description uses an LMF as an example.

[0017] The method may include: the LMF sending a measurement request message to the access network device, the measurement request message indicating the number of continuous measurement samples Nt configured by the LMF and enabling condition-based continuous measurement sample number reporting; the LMF receiving a measurement report message from the access network device, the measurement report message including the measurement results and the number of continuous measurement samples Nt actually selected by the access network device, the number of continuous measurement samples Nt actually selected by the access network device being inconsistent with the number of continuous measurement samples Nt configured by the LMF.

[0018] In one possible implementation, the above conditions may be: the number of continuous measurement samples actually selected by the access network device is less than the number of continuous measurement samples configured by the LMF, or the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF.

[0019] In one possible implementation, the measurement duration is determined based on the number of continuous measurement samples, the measurement granularity, and the basic time unit. If the number of continuous measurement samples actually selected by the access network device is inconsistent with the number of continuous measurement samples configured by the LMF, then the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF.

[0020] In one possible implementation, the measurement request message may include a measurement quantity request field. This measurement quantity request field can be used to indicate whether condition-based continuous measurement sample count reporting is enabled. The measurement quantity request field can be of Boolean type. If the measurement quantity request field is a first value (e.g., the first value is true), then the measurement quantity request field indicates whether condition-based continuous measurement sample count reporting is enabled; or, if the measurement quantity request field is a second value (e.g., the second value is false), then the measurement quantity request field indicates whether condition-based continuous measurement sample count reporting is enabled.

[0021] In one possible implementation, the aforementioned measurement request message can also be used to indicate the measurement type, which is a sample-based measurement.

[0022] In one possible implementation, the aforementioned measurement request message can also be used to indicate the number of samples Nt' to be reported in the LMF configuration, as well as the measurement granularity k. Here, the number of samples Nt' to be reported refers to the Nt' time-domain channel response values ​​selected from Nt consecutively measured channel response values, ordered according to received power.

[0023] In one possible implementation, the number of access network devices can be multiple. That is, the LMF can send measurement request messages to multiple access network devices and receive measurement report messages from multiple access network devices. The method may further include: the LMF grouping the multiple access network devices according to the actual number of continuous measurement samples selected by each access network device, with each access network device in the same group having the same number of continuous measurement samples selected. It is understood that the actual number of continuous measurement samples Nt selected by the multiple access network devices may differ. The LMF can group the multiple access network devices according to the actual number of continuous measurement samples, thereby ensuring consistency in the Nt value for each group, facilitating targeted reconfiguration and measurement.

[0024] In one possible implementation, multiple access network devices are grouped, including: LMF grouping the access network devices other than the first access network device among the multiple access network devices, where the number of continuous measurement samples Nt actually selected by the first access network device is less than or equal to a preset value. It can be understood that the first access network device is a node among the multiple access network devices with too few continuously selected measurement samples Nt. By excluding nodes with too few measurement samples before grouping, low-quality measurement data reporting is avoided, which would affect signaling overhead and AI model performance.

[0025] In one possible implementation, after grouping multiple access network devices, the method may further include: the LMF sending a measurement request message to the access network devices in the first group, wherein the actual measurement conditions of the access network devices in the first group support the positioning accuracy and latency requirements of the current AI model. It is understood that the positioning accuracy and latency requirements of the AI ​​model may change at different times. The LMF selects access network devices whose actual measurement conditions support the current positioning accuracy and latency requirements of the AI ​​model for targeted configuration, which is beneficial for improving the performance of the AI ​​model.

[0026] In one possible implementation, the measurement request message sent to the access network device in the first group includes at least one of the following: the measurement type after the configuration is updated, the number of samples for continuous measurement after the configuration is updated, the number of samples for reporting after the configuration is updated, and the measurement granularity after the configuration is updated.

[0027] The second aspect is the implementation of the LMF side, which corresponds to the first aspect. The explanations, supplements, and descriptions of the beneficial effects of the first aspect also apply to the second aspect, and will not be repeated here.

[0028] Thirdly, a communication device is provided, comprising a transceiver module. The transceiver module is configured to: receive a measurement request message from an LMF (Local Modem), the measurement request message indicating the number of continuous measurement samples configured by the LMF and enabling condition-based continuous measurement sample count reporting; and send a measurement report message to the LMF, the measurement report message including measurement results and the number of continuous measurement samples actually selected by the access network device, wherein the number of continuous measurement samples actually selected by the access network device is inconsistent with the number of continuous measurement samples configured by the LMF.

[0029] Fourthly, a communication apparatus is provided, comprising a transceiver module. The transceiver module is configured to: send a measurement request message to an access network device, the measurement request message indicating the number of continuous measurement samples configured by the LMF and enabling condition-based continuous measurement sample count reporting; and receive a measurement report message from the access network device, the measurement report message including measurement results and the number of continuous measurement samples actually selected by the access network device, wherein the number of continuous measurement samples Nt actually selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF.

Optionally, the communication device further includes a memory.

[0056] Figure 1 This is a schematic diagram of a communication system 100 provided in an embodiment of this application.

[0057] Communication system 100 may include network devices, such as Figure 1 The network device 110 is shown. The communication system 100 may also include terminal devices, such as... Figure 1 The terminal device 120 shown. The network device 110 and the terminal device 120 can communicate via a wireless link.

[0059] The network devices in this application embodiment can be network-side devices such as access network devices and core network devices. Access network devices are sometimes also called access nodes. Access network devices have wireless transceiver capabilities and are used to communicate with terminal devices. Access network devices include, but are not limited to, base stations, evolved NodeBs (eNodeBs), TRPs, gNBs in 5G mobile communication systems, next-generation eNodeBs (ng-eNBs) in 5G mobile communication systems, access network devices or modules of access network devices in open RAN (ORAN) systems, satellites in NTN communication systems, base stations in future mobile communication systems, or access nodes in wireless fidelity (Wi-Fi) systems. Access network devices can also be modules or units capable of implementing some of the functions of a base station. Access network devices can be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, or wireless controllers in cloud radio access network (CRAN) scenarios.

Multiple access network devices in a communication system can be base stations of the same type or different types. Base stations can communicate directly with terminal devices or through relay stations. Terminal devices can communicate with multiple base stations using different access technologies. This application does not limit the specific technology or device form used in the access network devices.

[0060] In practical applications, multiple network devices can collaborate to assist terminal devices in achieving wireless access, with different network devices each implementing a portion of the base station's functions. For example, network devices can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0061] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be any device capable of supporting the network device in implementing that function, such as a processor, circuit, chip, or chip system. This device can be installed in the network device or connected to and used with the network device. In the technical solution provided in this application, the example of a network device being used to implement the function of the network device is used to describe the technical solution provided in this application.

[0062] The terminal device in this application embodiment can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device providing voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. For example, the terminal device can communicate with one or more core networks or the Internet via a radio access network (RAN). The terminal device can also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), ultra-reliable low-latency communication (URLLC), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, or satellite communication, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, aircraft (such as drone, helicopter, airplane), hot air balloon, ship, robot, robotic arm, or smart home device, etc. The embodiments of this application do not limit the form of the terminal device.

[0063] In the embodiments of this application, the device for implementing the functions of the terminal device can be the terminal device itself, or any device capable of supporting the terminal device in implementing the functions, such as a processor, circuit, chip, or chip system. This device can be installed in the terminal device or connected to and used with the terminal device. In the technical solutions provided in this application, the terminal device is used as an example to illustrate the technical solutions provided in this application.

[0064] Access network equipment and / or terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; or in the air on aircraft, balloons, and satellites. This application does not limit the application scenarios of the access network equipment and terminal equipment. They can be deployed in the same or different scenarios; for example, both can be deployed on land simultaneously; or the access network equipment can be deployed on land while the terminal equipment is deployed on water, etc., and so on.

[0065] Figure 2 This is a schematic diagram of a communication system 200 for wireless positioning provided in an embodiment of this application.

[0066] The communication system 200 can be applied to 5G NR or evolved universal terrestrial radio access (E-UTRA). The communication system 200 may include functional entities such as terminal equipment, access network equipment, and core network equipment. These functional entities communicate with each other through corresponding interfaces. Figure 2 As shown, terminal devices can communicate with each other via the proximity-based services communication 5 (PC5) interface, while gNB or ng-eNB communicates with terminal devices via the radio interface between UTRAN and Uu interface. For example, terminal devices can connect to access network equipment via ng-eNB through the LTE-Uu interface. Terminal devices can also connect to access network equipment via gNB through the NR-Uu interface.

[0067] Access network equipment refers to devices within an access network that primarily perform functions such as resource scheduling, radio resource management, and radio resource control for terminal devices. For example, an access network can be configured as follows: Figure 2 The diagram shows a next-generation radio access network (NG-RAN). NG-RAN can include one or more access network devices, such as... Figure 2The gNB and ng-eNB are shown. In one possible implementation, the gNB can also be a TRP or transmission measurement function (TMF), and the ng-eNB can also be a TRP or transmission point (TP), etc. Access network devices can communicate with core network devices via wired or wireless means, for example through... Figure 2 The NG-C interface shown connects to the core network. The radio access network is capable of transmitting positioning reference signals (PRS), receiving sounding reference signals (SRS), and acquiring relevant measurement information.

[0068] Access network equipment can cover one or more cells, such as access network equipment 1 covering cells 1 and 2, and access network equipment 2 covering cell 3. A terminal device can camp on an access network equipment in one of the cells, existing in a connected state. Further, the terminal device can transition from a connected state to an inactive state (i.e., a disconnected state) through a radio resource control (RRC) release process. A terminal device in a disconnected state can remain in its original cell and, based on its transmission parameters in the original cell, perform uplink and / or downlink transmissions with the access network equipment in that cell. A terminal device in a disconnected state can also move to a new cell and, based on its transmission parameters in the new cell, perform uplink and / or downlink transmissions with the access network equipment in the new cell.

[0069] Core network equipment is primarily used for network management, control, and data transmission. Core network equipment may include, for example... Figure 2 The shown entities or network elements include access and mobility management functions (AMF), LMF, etc.

[0070] AMF can receive location service requests related to terminal devices from the location service (LCS) entity of the 5G core network (5GC) or other network elements. Alternatively, AMF itself can initiate some location services on behalf of a specific terminal device and forward the location service requests to LMF.

[0071] The Location Facilitator (LMF) is responsible for supporting different types of location services for terminal devices, calculating and feeding back location information within the network, and providing functions such as positioning process management, terminal capability acquisition, auxiliary data provision, and terminal location estimation. Specifically, it provides the following functions: supporting terminal device location calculation, obtaining downlink location measurements or estimates from terminal devices, and obtaining uplink location measurements from the NG-RAN. The LMF's control plane and user plane are the Enhance-Serving Mobile Location Center (E-SMLC) and the Secure User Plane Locator Platform (SLP), respectively. The LMF can interact with the NG-RAN and terminal devices. For example, the LMF exchanges information with the gNB or ng-eNB via New Radio Positioning Protocol (NRPPa) messages, such as obtaining PRS and SRS configuration information, cell timing, and cell location information. Furthermore, the LMF communicates with terminal devices via LTE Positioning Protocol (LPP) messages to transmit terminal device capability information, auxiliary information, and measurement information.

[0072] It should be noted that, Figure 2 This is just an example framework diagram. Figure 2 The number of nodes, cells, and the status of terminal devices included are unlimited. Except... Figure 2 In addition to the functional nodes shown, other nodes may also be included, such as gateway devices and application servers.

[0073] To facilitate understanding of the embodiments of this application, the terminology used in these embodiments is briefly explained below. Optionally, the explanation of some terms may also refer to the explanations in the 3rd Generation Partnership Project (3GPP) standard protocol. It should be understood that the technical terminology in the embodiments of this application is only illustrative and not limiting. For example, as technology evolves, technical terminology may also change; where the technical meaning remains the same, other technical terms should also apply to this application.

[0074] Location is a crucial function in mobile communication systems, providing users with real-time location information. The widespread deployment of 5G networks has spurred the demand for high-precision wireless positioning. Wireless positioning plays a vital role in scenarios such as enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communications (URLLC). Positioning technologies can include uplink positioning, downlink positioning, and uplink-downlink positioning. Uplink positioning involves the network device measuring the SRS signal sent by the terminal device, while downlink positioning involves the terminal device measuring the PRS signal sent by the network device. Uplink-downlink positioning requires both the terminal device to measure the PRS signal sent by the network device and the network device to measure the SRS signal sent by the terminal device.

[0075] Driven by 3GPP standards, AI / ML has become a key means to improve the accuracy and robustness of wireless positioning. This application provides two types of AI / ML-based wireless positioning technologies: one is AI / ML-assisted positioning, used to improve the performance of traditional geometric positioning methods, such as AI-enhanced time of arrival (TOA) / time difference of arrival (TDOA) estimation and angle estimation; the other is direct AI / ML positioning, including fingerprint positioning, knowledge-assisted AI positioning, and channel mapping methods, which directly predict location through wireless signal characteristics. For both types of wireless positioning technologies, the AI ​​model can be set in the terminal device, the access network device, or the core network device.

[0076] Figure 3 The diagram illustrates five AI-based localization methods provided in the embodiments of this application.

[0077] in, Figure 3 (1) Figure 3 (3) and Figure 3 (5) in the middle refers to direct AI / ML localization. Figure 3 (2) and Figure 3 (4) in the text refers to AI / ML assisted localization.

[0078] like Figure 3As shown in (1), the gNB sends a PRS signal to the UE, and the UE can perform direct AI / ML positioning based on the AI ​​model set on the UE side and report the UE's location information to the LMF.

[0079] like Figure 3 As shown in (2), the gNB sends a PRS signal to the UE, and the UE can report reference signal (RS) measurement information to the LMF based on the AI ​​model set on the UE side to assist the LMF in positioning.

[0080] like Figure 3 As shown in (3), the gNB sends a PRS signal to the UE, and the UE can report RS measurement information to the LMF. The LMF performs direct AI / ML positioning based on the RS measurement information and the AI ​​model set on the LMF side.

[0081] like Figure 3 As shown in (4), the UE reports the SRS signal to the gNB, and the gNB can report RS measurement information to the LMF based on the AI ​​model set on the gNB side to assist the LMF in positioning based on the RS measurement information.

[0082] like Figure 3 As shown in (5), the UE reports the SRS signal to the gNB, and the gNB can report the RS measurement information to the LMF. The LMF performs direct AI / ML positioning based on the RS measurement information and the AI ​​model set on the LMF side.

[0083] exist Figure 3 (3) and Figure 3 In the positioning method shown in (5), the AI ​​model is set on the LMF side. The LMF can be dynamically configured to use two measurement modes: sample-based measurement and path-based measurement. Since the measurement accuracy and performance of these two measurement modes are different, they are suitable for different positioning scenarios and environmental conditions. The LMF supports inputting measurement data from a single measurement mode into the AI ​​model for training, or it can fuse measurement data from both measurement modes into the AI ​​model for training.

[0084] The following provides examples illustrating these two measurement modes.

[0085] Sample-based measurements:

[0086] Definition: Directly acquire raw channel impulse response (CIR) samples in the time or frequency domain, which contain complete multipath information, such as phase, amplitude, and time delay.

[0087] Data characteristics: 1. Retain original signal features such as phase, amplitude and time delay; 2. High data dimension, a single sample point can reach Nsc×Nsym in a typical scenario, where Nsc represents the number of subcarriers and Nsym represents the number of symbols.

[0088] Path-based measurement:

[0089] Definition: Extract multipath component parameters through a channel estimation algorithm, such as time delay τ, Angle of Arrival AoA, Angle of Departure AoD, Doppler shift ν, etc.

[0090] Data characteristics: 1. Structured parameter output, each path corresponds to a parameter vector: [τ, AoA, AoD, ν, P], where P is the path power; 2. Low data dimension, only 5-10 main path parameters are required per link in a typical scenario.

[0091] Exemplarily, Table 1 shows the differences between the two measurement modes in terms of positioning accuracy, delay sensitivity, applicable environment, standardization progress and typical use cases.

[0092] Table 1

[0093]

[0094] The path-based measurement configuration can follow the R18 protocol, but the sample-based measurement configuration requires a larger number of measurements, which requires enhancement of the traditional measurement configuration. In the embodiments of the present application, the sample-based measurement configuration may include the following parameters:

[0095] Number of consecutively measured channel response values Nt: represents the number of consecutively measured sample points in the time domain, also referred to as the number of consecutively measured sample points Nt. The time granularity of these channel response values is T. In a possible implementation, Nt={32, 64, 128}, that is, the number of consecutively measured sample points in the time domain may be 32, 64 or 128.

[0096] Number of reported estimated channel response values Nt': also referred to as the number of reported sample points Nt', which refers to Nt' time-domain channel response values selected from the Nt consecutively measured channel response values according to the received power ranking, for example, Nt' time-domain channel response values with the highest numerical values selected in descending order of received power. Wherein Nt'<Nt. In a possible implementation, Nt'={9, 16, 24}, that is, 9, 16 or 24 time-domain channel response values are selected according to the received power ranking.

[0097] Measurement time granularity T: represents the time interval between two consecutively measured sample points. In a possible implementation, T=2 k×Tc. Where k is the measurement granularity, and Tc is the basic time unit of NR, for example, Tc=1 / (480k×4096)≈5.086×10 -10 In one possible implementation, the set of values ​​for k is {-6, -5, -4, -3, -2, -1}; in another possible implementation, the set of values ​​for k is {0, 1, 2, 3, 4, 5}. It should be noted that "two consecutively measured sample points" means measuring one sample point followed by the next, with a time interval of T between the two measurements.

[0098] As described above, for sample-based measurement mode, the LMF can be configured with at least three parameters: the number of continuously measured samples Nt, the number of reported samples Nt', and the measurement granularity k. The LMF sends configuration information including these parameters to the access network device, which can respond to the configuration information to measure the uplink reference signal (such as the SRS signal sent by the target UE) and send a measurement report to the LMF.

[0099] Typically, the number of continuous measurement samples Nt, the number of reported samples Nt', and the measurement granularity k configured in the LMF are consistent with the number of continuous measurement samples Nt, the number of reported samples Nt', and the measurement granularity k actually selected by the access network equipment. However, in certain special circumstances, such as when there is network congestion, high network load, high-speed movement of terminal equipment, or when the network capacity is exceeded, the number of continuous measurement samples Nt, the number of reported samples Nt', and the measurement granularity k configured in the LMF may not be consistent with the number of continuous measurement samples Nt, the number of reported samples Nt', and the measurement granularity k actually selected by the access network equipment.

[0100] LMF can calculate the number of sample points Nt' of the report actually selected by the access network device based on the multipath power information, multipath phase information and / or multipath delay information contained in the measurement report, and thus determine whether the number of sample points Nt' of the report configured by LMF is consistent with the number of sample points Nt' of the report actually selected by the access network device.

[0101] Furthermore, the measurement granularity k is closely related to the number of reported samples Nt'. For example, taking an NG-RAN node as an access network device, the LMF can calculate the number of reported samples Nt' actually selected by the NG-RAN node based on the number of channel impulse response samples included in the measurement report. If there are two consecutive samples in the NG-RAN node's measurement report, the LMF can calculate the measurement granularity k actually selected by the NG-RAN node based on the time interval between these two samples, thereby determining whether the measurement granularity k configured by the LMF is consistent with the measurement granularity k actually selected by the NG-RAN node.

[0102] LMF can know the number of sample points Nt' and measurement granularity k actually selected by the access network device from the measurement report, but it cannot know the number of sample points Nt actually selected for continuous measurement by the access network device. Therefore, LMF can determine whether the number of sample points Nt' and measurement granularity k configured by LMF are consistent with the number of sample points Nt' and measurement granularity k actually selected by the access network device, but it cannot determine whether the number of sample points Nt configured by LMF for continuous measurement is consistent with the number of sample points Nt actually selected for continuous measurement by the access network device.

[0103] If the LMF cannot know the actual number of continuous measurement samples Nt selected by the access network device, the following two measurement scenarios will present problems.

[0104] For measurement scenarios involving a single access network device:

[0105] Figure 4 This diagram illustrates how the Nt actually selected for the access network equipment provided in this application is less than the Nt configured in the LMF. The horizontal axis represents time, and the vertical axis represents the channel response value. At any given moment, one sample corresponds to one channel response value.

[0106] Taking the LMF configuration with a continuous measurement sample number Nt = 32 and a reported sample number Nt' = 16 as an example.

[0107] like Figure 4 As shown in (a), if a single access network device continuously measures 32 sample points according to the LMF configuration, and then selects the 16 sample points with the highest received power based on the receiving power sorting results corresponding to the 32 sample points, and then reports the measurement report of these 16 sample points to the LMF, that is, Nt=32, Nt'=16.

[0108] like Figure 4 As shown in (b), due to network congestion, high network load, high-speed movement of terminal devices, or exceeding network capacity, the number of continuous measurement samples actually selected by the access network device is Nt = 26, which is less than the number of continuous measurement samples Nt = 32 configured by the LMF. For example, the access network device may not actually measure the 6 samples within the dashed box. This will cause changes in the sample points in the access network device's screening report. For example, the sample points in the final screening report may include, for example, the sample points in the final screening report may include, Figure 4 The 10 sample points shown in (a) excluding the 6 sample points within the dashed box, and as shown in... Figure 4 The six newly added sample points are shown in (b) in the figure.

[0109] In the above scenario, because the LMF cannot know the actual number of continuously measured samples from the access network equipment, it may assume that the measured values ​​of the six samples within the dashed box time are very small, and therefore fall to the end of the sorting by received power (i.e., not meeting the reporting conditions). This leads to the measurement results of these nodes not being reported, causing a misunderstanding of the current channel environment state, and consequently resulting in errors in its estimated multipath delay spread and angle spread. If the LMF inputs insufficient and inaccurate measurement data into the AI ​​model, it will affect the training and inference performance of the AI ​​model.

[0110] Scenarios involving collaboration of multiple access network devices:

[0111] Because multiple access network devices implement different strategies, their environmental estimation performance may vary, leading to increased measurement errors in joint positioning. Certain access network devices, or even a single access network device, may degrade overall cooperative positioning performance, further increasing measurement errors.

[0112] In view of this, this application provides a measurement configuration method. This method can be applied to the communication system provided in the above embodiments, such as... Figure 1 or Figure 2 The communication system shown is described above. For sample-based measurement modes, when the number of continuous measurement samples Nt actually selected by the access network device differs from the number of continuous measurement samples Nt configured by the LMF, the access network device can include the actually selected number of continuous measurement samples Nt in the measurement report. This way, when the LMF learns that the number of continuous measurement samples Nt actually selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF, it can perform preprocessing operations to avoid increasing measurement errors, thereby improving the training and inference performance of the AI ​​model.

[0113] The following detailed description of the solution provided in the embodiments of this application, in conjunction with the corresponding flowcharts, is provided. It is understood that the illustrative flowcharts provided in the embodiments of this application primarily use different devices (e.g., LMF and access network devices) as examples of the execution subjects of the interaction to illustrate the method, but this application does not limit the execution subjects of the interaction. For example, the devices in the illustrative flowcharts (e.g., LMF and access network devices) can also be chips, chip systems, or processors that support the implementation of the method by the device, or logic modules or software capable of implementing all or part of the functions of the device.

[0114] As a general statement, the message or signaling interactions involved in the interaction process of this application embodiment can be standard messages or signaling or newly introduced messages or signaling. This application embodiment does not make specific limitations on this.

[0115] Figure 5 This is a schematic diagram of a measurement configuration method according to an embodiment of this application. It can be understood that... Figure 5LMF in the text can be Figure 2 The LMF device in the text can also refer to the device (such as a processor, chip, or chip system) in the LMF device. The LMF can be equipped with an AI model for positioning. Figure 5 The access network equipment in the middle can be Figure 1 or Figure 2 The term "access network equipment" can refer to devices within the access network equipment, such as gNB or TRP, or even to processors, chips, or chip systems.

[0116] like Figure 5 As shown, the method may include the following steps S501 to S502.

[0117] S501, the LMF sends a measurement request message to the access network device, and the access network device receives the measurement request message from the LMF. This measurement request message indicates the number of continuous measurement samples Nt configured by the LMF and enables condition-based continuous measurement sample number reporting.

[0118] The aforementioned measurement request message can be used to instruct access network devices to perform location measurements.

[0119] In this embodiment, the LMF can be dynamically configured to use both sample-based and path-based measurement modes. The LMF supports inputting measurement data from a single measurement mode into an AI model for training, or it can fuse measurement data from both measurement modes. When requesting a location measurement, the LMF can indicate the measurement type via a measurement request message, which can be either sample-based or path-based measurement.

[0120] Based on the description of the above embodiments, when the measurement type configured by the LMF is path-based measurement, the R18 protocol can be used, and this application embodiment will not elaborate further. In one possible implementation, when the measurement type configured by the LMF is path-based measurement, the measurement request message sent by the LMF to the access network device may not include a measurement quantity request field, that is, there is no need to indicate whether to enable condition-based continuous measurement sample count reporting.

[0121] Compared to path-based measurement configurations, sample-based measurement configurations require a larger number of measurements. For sample-based measurements, if the number of continuous measurement samples Nt configured by the LMF (Local Method Provider) differs from the number of continuous measurement samples Nt actually selected by the access network device, the LMF may misinterpret the current channel environment state, leading to errors in its estimated multipath delay spread and angle spread, thus affecting the training and inference performance of the AI ​​model. Therefore, when the measurement type configured by the LMF is sample-based, the LMF can instruct the enabling of condition-based continuous measurement sample number reporting via a measurement request message. For example, the measurement request message may include a measurement quantity request field, which can be used to instruct the enabling of condition-based continuous measurement sample number reporting. This allows the LMF to determine whether the number of continuous measurement samples Nt configured by the LMF matches the number of continuous measurement samples Nt actually selected by the access network device after the access network device reports the actual number of continuous measurement samples Nt.

[0122] In one possible implementation, the aforementioned measurement request message can be an NRPPa measurement request message. The NRPPa protocol is the NR positioning protocol, supporting the transmission of messages, such as measurement request messages and measurement report messages, between the LMF and NG-RAN nodes in the NR system. It is understood that for other communication systems, the measurement request message can also be based on other protocols; the embodiments of this application do not limit the protocol type of the measurement request message.

[0123] In one possible implementation, the condition in "enabling condition-based continuous measurement sample number reporting" can be any of the following:

[0124] Condition 1: The number of continuous measurement samples actually selected by the access network equipment is less than the number of continuous measurement samples configured by the LMF.

[0125] Condition 2: The actual measurement duration of the access network equipment is less than the measurement duration indicated by the LMF.

[0126] Typically, the number of continuous measurement samples Nt actually selected by the access network device is equal to the number of continuous measurement samples Nt configured by the LMF. When the number of continuous measurement samples Nt actually selected by the access network device is equal to the number of continuous measurement samples Nt configured by the LMF, the LMF can correctly assess the current channel environment state. In this case, the access network device does not need to report the number of continuous measurement samples Nt actually selected by the access network device to the LMF. However, in some scenarios, the number of continuous measurement samples Nt actually selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF.

[0127] In one scenario example, the access network device can adjust its number of continuous measurement samples Nt, causing it to select a different Nt value than the Nt value indicated by the LMF, such as... Figure 4 As shown, when the actual number of measurement samples by the access network device is insufficient, it will affect the sufficiency and accuracy of channel measurement information. In this scenario, the "condition" in S501 above can specifically be: Condition 1, the number of continuous measurement samples actually selected by the access network device is less than the number of continuous measurement samples configured by the LMF. It can be understood that the LMF, through the measurement quantity request field, instructs the access network device to enable continuous measurement sample number reporting based on condition 1, allowing the access network device to report the actual selected Nt value to the LMF when its selected Nt value is less than the Nt value indicated by the LMF.

[0128] In another scenario example, the measurement duration can be determined based on the number of consecutively measured samples Nt, the measurement granularity k, and the basic time unit Tc. For example, the measurement duration of an access network device can be determined using the formula Nt·2. k The value is calculated as ×Tc, where Nt represents the number of continuous measurement samples, k represents the measurement granularity, and Tc represents the basic time unit. Access network devices can adjust their number of continuous measurement samples Nt and measurement granularity k. When the number of continuous measurement samples Nt actually selected by the access network device differs from the number of continuous measurement samples Nt configured by the LMF, the actual measurement duration of the access network device will be less than the measurement duration indicated by the LMF. For example, if the number of continuous measurement samples Nt actually selected by the access network device is greater than the number of continuous measurement samples Nt configured by the LMF, and the actual measurement granularity k selected by the access network device is less than the measurement granularity k configured by the LMF, the actual measurement duration of the access network device will be less than the measurement duration indicated by the LMF. Similarly, if the number of continuous measurement samples Nt actually selected by the access network device is less than the number of continuous measurement samples Nt configured by the LMF, and the actual measurement granularity k selected by the access network device is less than or equal to the measurement granularity k configured by the LMF, the actual measurement duration of the access network device will be less than the measurement duration indicated by the LMF. For example, if the number of continuous measurement samples Nt actually selected by the access network device is less than the number of continuous measurement samples Nt configured by the LMF, and the measurement granularity k actually selected by the access network device is greater than the measurement granularity k configured by the LMF, then the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF. Insufficient actual measurement duration will also affect the sufficiency and accuracy of channel measurement information. In this scenario, the "condition" in S501 above can specifically be: condition 2 above, the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF. It can be understood that the LMF, through the measurement quantity request field, instructs the access network device to enable the continuous measurement sample count reporting based on condition 2, so that when the actual measurement duration selected by the access network device is less than the measurement duration indicated by the LMF, the access network device reports the Nt value actually selected by the access network device to the LMF.

[0129] In one possible implementation, the measurement request message can also be used to indicate the number of reported samples Nt' and the measurement granularity k configured by the LMF. Here, the number of reported samples Nt' refers to the Nt' time-domain channel response values ​​selected from Nt consecutively measured channel response values, ordered according to received power. It can be understood that by configuring the number of consecutively measured samples Nt, the number of reported samples Nt', and the measurement granularity k, the LMF enables the access network device to measure the SRS signal based on these parameters, thereby obtaining measurement results containing multipath information. Furthermore, when the measurement quantity request field is used to indicate enabling the reporting of the number of consecutively measured samples based on condition 2, the access network device can calculate the measurement duration indicated by the LMF based on these configuration parameters and determine whether the actual measurement duration selected by the access network device is less than the measurement duration indicated by the LMF.

[0130] In one possible implementation, the measurement quantity request field in the aforementioned measurement request message can be of Boolean type. If the measurement quantity request field has a first value, it can be used to indicate whether condition-based continuous measurement sample count reporting is enabled. Alternatively, if the measurement quantity request field has a second value, it can be used to indicate whether condition-based continuous measurement sample count reporting is enabled. For example, the first value is true and the second value is false; or the first value is false and the second value is true. It can be understood that adding a Boolean measurement quantity request field to the measurement request message is equivalent to setting an enable switch. By changing the value of the enable switch, LMF can indicate to the access network device whether to report the actually selected Nt value.

[0131] In one possible implementation, the LMF can set the value of the enable switch according to actual conditions. As an example, the LMF can periodically change the value of the enable switch, such as setting the measurement quantity request field to true at preset intervals. As another example, the LMF can set the value of the enable switch based on factors such as the current network environment, the current AI model's positioning accuracy, and latency requirements.

[0132] Below is an example of a measurement request message:

[0133]

[0134] In the above example, the measurement request message includes the Measurement Configuration field and the Measurement Amount Request field.

[0135] The Measurement Configuration field configures four parameters: Measurement Type, Number of Samples for Continuous Measurement Nt, Number of Samples for Reporting Nt', and Measurement Granularity k. These four parameters are enumeration types. Specifically, the Measurement Type can be either sample-based or path-based; the Number of Samples for Continuous Measurement Nt can be 32, 64, or 128; the Number of Samples for Reporting Nt' can be 9, 16, or 24; and the Measurement Granularity k can be 0, 1, 2, 3, 4, or 5.

[0136] The MeasurementAmount Request field is of Boolean type. If the MeasurementAmount Request field is true, it indicates that condition-based continuous measurement sample count reporting is enabled; otherwise, if the MeasurementAmount Request field is false, it indicates that condition-based continuous measurement sample count reporting is disabled.

[0137] It should be noted that in the embodiments of this application, "enable" can be understood as "activate", and "enable condition-based continuous measurement sample number reporting" means allowing the access network settings to report the actual number of continuous measurement samples Nt to the LMF when the conditions are met; "de-enable" can be understood as "deactivate", and "de-enable condition-based continuous measurement sample number reporting" means prohibiting the access network device from reporting the actual number of continuous measurement samples Nt to the LMF regardless of whether the conditions are met.

[0138] S502, the access network device sends a measurement report message to the LMF, and the LMF receives the measurement report message from the access network device. This measurement report message may include the measurement results and the number of continuous measurement samples Nt actually selected by the access network device, which may differ from the number of continuous measurement samples Nt configured by the LMF.

[0139] The above-mentioned "the number of continuous measurement samples Nt actually selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF" can be that the Nt value actually selected by the access network device is less than the Nt value configured by the LMF, or the Nt value actually selected by the access network device is greater than the Nt value configured by the LMF.

[0140] After receiving the measurement request message, the access network device can measure the SRS signal reported by the terminal device according to the configuration parameters contained in the measurement request message, thereby obtaining the measurement result containing multipath information.

[0141] In one possible implementation, the above measurement results may include at least one of multipath power information, multipath phase information, and multipath time delay information.

[0142] For example, measurement results may include: uplink angle of arrival (ULAoA), uplink sounding reference signal reference signal received power (UL SRS-RSRP), uplink radio transmit on arrival measurement (UL RTOA measurement), gNB Rx-Tx time difference, vertical angle of arrival (AoA), multiple UL-AOA, and / or receive signal channel power (ULRSCP), etc.

[0143] According to the description in S501 above, the measurement quantity request field in the measurement request message is of Boolean type. The LMF can set the value of the measurement quantity request field to true or false as needed. After receiving the measurement request message, the access network device can perform any of the following operations based on the specific value of the measurement quantity request field:

[0144] If the Measurement Quantity Request field is true, it is determined that the number of continuous measurement samples actually selected by the access network device is less than the number of continuous measurement samples configured by the LMF (i.e., condition 1 is met), or the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF (at this point, the number of continuous measurement samples Nt actually selected by the access network device is greater than the number of continuous measurement samples Nt configured by the LMF, or the number of continuous measurement samples Nt actually selected by the access network device is less than the number of continuous measurement samples Nt configured by the LMF, i.e., condition 2 is met). When condition 1 or condition 2 is met, the access network device provides the LMF with the number of continuous measurement samples Nt actually selected by the access network device, so that the LMF knows that the number of continuous measurement samples Nt actually selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by the LMF.

[0145] If the Measurement Quantity Request field is true, it is determined that the number of continuous measurement samples actually selected by the access network device is equal to the number of continuous measurement samples configured by the LMF (i.e., condition 1 is not met), or the actual measurement duration of the access network device is equal to the measurement duration indicated by the LMF (at this time, the number of continuous measurement samples Nt actually selected by the access network device is consistent with the number of continuous measurement samples Nt configured by the LMF, i.e., condition 2 is not met). When conditions 1 and 2 are not met, the access network device may not provide the LMF with the number of continuous measurement samples Nt actually selected by the access network device. That is, the measurement report message does not include the number of continuous measurement samples Nt actually selected by the access network device. The LMF assumes that the number of continuous measurement samples Nt actually selected by the access network device is consistent with the number of continuous measurement samples Nt configured by the LMF, thereby reducing signaling overhead.

[0146] If the Measurement Quantity Request field is false, LMF does not care whether the number of continuous measurement samples Nt actually selected by the access network device is consistent with the number of continuous measurement samples Nt configured by LMF. Regardless of whether conditions 1 and 2 are met, the measurement report message does not include the number of continuous measurement samples actually selected by the access network device.

[0147] In one possible implementation, the measurement report message includes a measurement quantity field, which is of type enumeration and indicates the number of continuous measurement samples Nt actually selected by the access network device. For example, the number of continuous measurement samples Nt actually selected by the access network device can be any value among 9, 16, 24, 32, 64, and 128.

[0148] It is understood that the Measurement Quantity field is optional. When the Measurement Quantity Request field is true and either Condition 1 or Condition 2 is met, the measurement report message includes the Measurement Quantity field. When the Measurement Quantity Request field is false and neither Condition 1 nor Condition 2 is met, the measurement report message does not include the Measurement Quantity field. The measurement report message also does not include the Measurement Quantity field when the Measurement Quantity Request field is false.

[0149] Below is an example of a measurement report message:

[0150] MEASUREMENT REPORT:=:SEQUENCE{

[0151]

[0152] In the above example, the measurement report message includes the TRP Measurement Result field. The TRP Measurement Result field includes: Measurement Results Value, Time Stamp, Measurement Quality, and Measurement Amount.

[0153] Below is an example description of the measurement quantity field:

[0154] Example 1: If the Measurement Quantity Request field is true, and the number of continuous measurement samples Nt actually selected by the access network device is less than the number of continuous measurement samples Nt configured by the LMF, then the Measurement Quantity field will be presented in the measurement report message.

[0155] Example 2: If the measurement quantity request field is true, and the access network device selects different continuous measurement sample number Nt or measurement granularity k, the actual measurement duration Nt·2 k ×Tc is less than the measurement duration Nt·2 indicated by LMF. k If ×Tc is used, then the measurement quantity field will be displayed in the measurement report message.

[0156] In the above method, LMF adds a measurement quantity request field to the measurement request message to indicate whether condition-based continuous measurement sample number reporting is enabled. This allows the access network device to include the actual number of continuous measurement samples Nt selected by the access network device in the measurement report when the conditions are met. Thus, LMF can detect that the actual number of continuous measurement samples Nt selected by the access network device is inconsistent with the number of continuous measurement samples Nt configured by LMF, thereby more accurately estimating multipath delay spread and angle spread, avoiding increased measurement errors, and improving the inference performance of the AI ​​model.

[0157] It should be noted that the number of access network devices in the above embodiments can be one or more. When there are multiple access network devices, these multiple access network devices can be understood as all measurement entities. Specifically, the LMF can send measurement request messages to multiple access network devices. Correspondingly, each of the multiple access network devices can receive the measurement request message from the LMF and send its own corresponding measurement report message to the LMF.

[0158] Below Figure 5 Based on the provided measurement configuration method, combined with Figure 6 This application provides another measurement configuration method. It can be understood that... Figure 6 LMF in the text can be Figure 2The LMF device in the context can also refer to the components within the LMF device (such as processors, chips, or chip systems). Figure 6 The access network equipment in the middle can be Figure 1 or Figure 2 The term "access network equipment" can refer to devices within the access network equipment, such as gNB or TRP, or even individual components (e.g., processors, chips, or chip systems). Figure 6 As shown, the method may include the following steps S601 to S607.

[0159] S601, the LMF sends measurement request messages to multiple access network devices respectively, and each of the multiple access network devices receives a measurement request message from the LMF. The measurement request message can be used to indicate the number of continuous measurement samples Nt configured by the LMF, and to enable condition-based continuous measurement sample count reporting.

[0160] In some embodiments, the measurement request message may include a measurement quantity request field, which may be used to indicate that condition-based continuous measurement sample count reporting is enabled.

[0161] S602, each of the multiple access network devices measures the SRS signal sent by the UE according to the measurement request message.

[0162] In one possible implementation, the measurement request message sent by the LMF may also include SRS configuration information. Each access network device can measure the SRS signal reported by the terminal device according to the SRS configuration information, as well as the number of continuous measurement samples Nt, the number of reported samples Nt', and the measurement granularity k configured by the LMF, thereby obtaining the measurement result corresponding to the access network device. The measurement result may include at least one of multipath power information, multipath phase information, and multipath delay information.

[0163] It is understandable that the specific values ​​of multipath power information, multipath phase information, and multipath delay information obtained from measurements may differ for different access network devices.

[0164] S603, each of the multiple access network devices sends its corresponding measurement report message to the LMF, and the LMF receives the measurement report messages from the multiple access network devices. Each access network device's measurement report message includes the measurement results of that access network device.

[0165] If the number of continuous measurement samples Nt actually selected by an access network device is equal to the number of continuous measurement samples Nt configured by the LMF, then this access network device does not need to report the number of continuous measurement samples Nt actually selected by the access network device to the LMF. That is, the measurement report message sent by this access network device does not carry the number of continuous measurement samples Nt actually selected by the access network device. At this time, the LMF assumes that the number of continuous measurement samples Nt actually selected by the access network device is equal to the number of continuous measurement samples Nt configured by the LMF.

[0166] If the actual number of continuous measurement samples Nt selected by an access network device is less than the number of continuous measurement samples Nt configured by the LMF, or if the actual measurement duration Nt·2 of an access network device is... k ×Tc is less than the measurement duration Nt·2 indicated by LMF. k If ×Tc, then the access network device needs to report the number of continuous measurement samples Nt that the access network device actually selected to the LMF. That is, the measurement report message sent by the access network device carries the number of continuous measurement samples Nt that the access network device actually selected. The number of continuous measurement samples actually selected by the access network device is inconsistent with the number of continuous measurement samples configured by the LMF.

[0167] S604, LMF groups multiple access network devices according to the number of continuous measurement samples Nt actually selected by each access network device in the group, and the number of continuous measurement samples actually selected by access network devices in the same group is the same.

[0168] For example, Table 2 shows the correspondence between the number of continuous measurement samples Nt actually selected by the access network equipment and the number of packets. As shown in Table 2, the access network equipment includes gNB1, gNB2, gNB3, gNB4, gNB5, gNB6, gNB7, gNB8, gNB9, gNB10, gNB11, gNB12, TRP1, TRP2, TRP3, TRP4 and TRP5. Specifically, gNB1 has 9 sample points selected for continuous measurement (Nt), gNB2, gNB3, and gNB4 have 16 sample points selected for continuous measurement (Nt), gNB5, gNB6, and TRP1 have 24 sample points selected for continuous measurement (Nt), gNB7, gNB8, gNB9, and TRP2 have 32 sample points selected for continuous measurement (Nt), gNB10, TRP3, and TRP4 have 64 sample points selected for continuous measurement (Nt), and gNB11, gNB12, and TRP5 have 128 sample points selected for continuous measurement (Nt). LMF can group access network devices with the same number of sample points selected for continuous measurement into the same group. For example, gNB1 is assigned to group 1, gNB2, gNB3, and gNB4 are assigned to group 2, gNB5, gNB6, and TRP1 are assigned to group 3, gNB7, gNB8, gNB9, and TRP2 are assigned to group 4, gNB10, TRP3, and TRP4 are assigned to group 5, and gNB11, gNB12, and TRP5 are assigned to group 6.

[0169] Table 2

[0170] The actual number of continuous measurement samples selected, Nt Grouping results 9 Group 1 (gNB1) 16 Group 2 (gNB2, gNB3, gNB4) 24 Group 3 (gNB5, gNB6, TRP1) 32 Group 4 (gNB7, gNB8, gNB9, TRP2) 64 Group 5 (gNB10, TRP3, TRP4) 128 Group 6 (gNB11, gNB12, TRP5)

[0171] It is understandable that the number of continuous measurement samples Nt selected by multiple access network devices may differ. LMF can group multiple access network devices according to the actual number of continuous measurement samples, so that the Nt value of each group is consistent, which facilitates targeted reconfiguration and measurement.

[0172] In one possible implementation, the above-mentioned grouping of multiple access network devices based on the actual number of continuous measurement samples selected by each access network device includes: grouping access network devices other than the first access network device, where the actual number of continuous measurement samples selected by the first access network device is less than or equal to a preset value. For example, if the preset value is 16, then after excluding gNB1, gNB2, gNB3, and gNB4 in Table 2, the other access network devices can be grouped into groups 3, 4, 5, and 6. It can be understood that the first access network device is a node among the multiple access network devices with too few actual continuous measurement samples Nt. By excluding nodes with too few measurement samples before grouping, low-quality measurement data reporting is avoided, which affects signaling overhead and AI model performance.

[0173] In step S605, the LMF selects access network devices (referred to as the access network devices in the first group) whose positioning accuracy and latency requirements are supported by the actual measurement conditions, based on the current AI model's positioning accuracy and latency requirements. The first group is a subset of the multiple groups obtained through step S604, and the access network devices in the first group have actual measurement conditions that support the current AI model's positioning accuracy and latency requirements.

[0174] It is understandable that the positioning accuracy and latency requirements of the AI ​​model may change at different times. Based on the current positioning accuracy and latency requirements of the AI ​​model, LMF selects access network equipment that supports the actual measurement conditions for targeted configuration, which is beneficial to improving the performance of the AI ​​model.

[0175] Table 3 below shows the correspondence between measurement accuracy requirements and measurement configurations. Measurement accuracy requirements can include at least one of the following: time measurement accuracy requirements, angle measurement accuracy requirements, and intensity measurement accuracy requirements. Different measurement accuracy requirements correspond to different measurement configurations. It can be understood that the higher the measurement accuracy requirement, the larger the required sample point values.

[0176] Table 3

[0177]

[0178] Table 4 below shows the correspondence between measurement delay requirements and measurement configurations. Different measurement delay requirements correspond to different measurement configurations. It can be understood that the shorter the measurement delay requirement, the smaller the required sample value.

[0179] Table 4

[0180]

[0181] S606, LMF updates the measurement configuration for the first group.

[0182] In one possible implementation, the updated measurement configuration of the first group may include at least one of the following: the updated measurement type, the updated number of continuous measurement samples Nt, the updated number of reported samples Nt', and the updated measurement granularity k. It can be understood that by updating the measurement configuration of the first group, the measurement configuration of the first group can be better adapted to the current AI model's positioning accuracy and latency requirements, thereby improving measurement reporting efficiency.

[0183] S607, LMF sends a measurement request message to the access network devices in the first group, whose actual measurement conditions support the positioning accuracy and latency requirements of the current AI model.

[0184] In one possible implementation, the measurement request message sent to the access network device in the first group may include at least one of the following: the measurement type after the configuration is updated, the number of samples for continuous measurement after the configuration is updated, the number of samples for reporting after the configuration is updated, and the measurement granularity after the configuration is updated.

[0185] In the above scheme, the LMF can group all access network devices based on measurement report messages from all access network devices, ensuring consistency of the Nt value for each group. This allows the LMF to select appropriate access network devices as measurement entities based on the current AI model's localization requirements. Since different measurement accuracies and different measurement delays correspond to different measurement configurations, the LMF can select a subset of access network devices with measurement configurations that simultaneously meet both accuracy and delay requirements as measurement entities. Furthermore, the LMF can adjust the grouping based on the access network device's measurement report messages, iteratively optimizing the grouping to maintain consistency in measurement conditions among access network nodes within the same group.

[0193] The processing module 720 can be used to group multiple access network devices according to the number of continuous measurement samples actually selected by each access network device, with the number of continuous measurement samples actually selected by access network devices in the same group being the same.

[0198] The processing module 720 is used to determine, when the measurement quantity request field is a first value (e.g., the first value is true), that the number of continuous measurement samples actually selected by the access network device is less than the number of continuous measurement samples configured by the LMF, or that the actual measurement duration of the access network device is less than the measurement duration indicated by the LMF.
