[0025] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0026] Wireless communication system

[0027] Figure 1 is an example diagram of the system architecture of a wireless communication system 100 to which embodiments of this application can be applied. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network, such as a wireless network, through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity; this embodiment of the application does not limit this.

[0028] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as fifth-generation (5G) systems, new radio (NR) systems, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems, such as sixth-generation mobile communication systems, satellite communication systems, and so on.

[0029] In this application embodiment, the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user apparatus. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. Terminal devices can also be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes. Optionally, terminal devices can act as base stations. For example, a terminal device can act as a dispatching entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0030] In this embodiment, the network device can be a device used to communicate with a terminal device. The network device can be an access network device or a wireless access network device. For example, the network device can be a base station. The term "base station" can broadly encompass various names as follows, or can be replaced by names such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master station (MeNB), secondary station (SeNB), multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar entity, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, or an entity that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or an entity that performs base station functions in future communication systems. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0031] Furthermore, base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station. In some deployments, network equipment can refer to a CU or DU; or, network equipment may include both CU and DU. Base stations may also include AAUs.

[0032] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0033] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform such as a cloud platform.

[0034] Neural networks (NN) and machine learning

[0035] A neural network is a computational model composed of multiple interconnected neurons. The connections between nodes represent weights, which are weights that represent the weighted sum of the input and output signals. Each node performs a weighted summation on different input signals and outputs the result through a specific activation function. For example, in the neuron structure shown in Figure 2, the summation (SUM) unit can process various dimensions of the neuron's input, enhancing or weakening it. The neuron's output, t, can be obtained through the activation function f.

[0036] As shown in Figure 3, the neural network includes an input layer, a hidden layer, and an output layer. Through different connections, weights, and activation functions of multiple neurons, it can produce different outputs, thereby fitting a mapping relationship from input to output. Each higher-level node is connected to all its lower-level nodes. This fully connected model can also be referred to as a deep neural network (DNN) in this embodiment, and it can be used as the neural network model in this embodiment.

[0037] The neural network in this embodiment can also be a convolutional neural network (CNN). As shown in Figure 4, the basic structure of a CNN includes an input layer, multiple convolutional layers, multiple pooling layers, a fully connected layer, and an output layer. Each neuron in the convolutional kernel of the convolutional layer is locally connected to its input. By introducing pooling layers, features of local maximum or average values ​​in a certain layer are extracted, effectively reducing the network parameters and mining local features, enabling the CNN to converge quickly and exhibiting excellent performance.

[0038] The neural network in this embodiment can also be a recurrent neural network (RNN). An RNN is a type of neural network that models sequential data and has achieved significant success in natural language processing applications such as machine translation and speech recognition. Specifically, the network remembers information from past time steps and uses it in the calculation of the current output; that is, the nodes between hidden layers are no longer disconnected but connected, and the input to the hidden layer includes not only the input layer but also the output of the hidden layer from the previous time step. Commonly used RNNs include long short-term memory (LSTM) networks and gated recurrent units (GRUs). For example, the basic LSTM unit structure shown in Figure 5, unlike RNNs which only consider the most recent state, determines which states should be retained and which should be forgotten based on the cell state of the LSTM, thus overcoming the shortcomings of traditional RNNs in long-term memory.

[0039] Positioning technology

[0040] Localization methods can generally be classified into the following categories:

[0041] 1) UE-based positioning method: The terminal device directly calculates the location of the target intermediate device.

[0042] 2) UE-assisted / Location Management Function (LMF) based positioning method: The terminal device performs positioning-related measurements and reports the measurement data to the LMF, which then calculates the location of the terminal device to be located based on the collected measurement data.

[0043] 3) NG-RAN node assisted positioning method: The base station reports the measurement data of the transmission / reception point (TRP) to the LMF, and the LMF calculates the location of the terminal device to be located based on the collected measurement data.

[0044] In the above positioning methods, the terminal device or LMF can apply relevant algorithms, such as the Chan algorithm and Taylor expansion, to calculate the location of the terminal device.

[0045] To support various positioning methods, related technologies introduce a positioning reference signal (PRS) in the downlink and a sounding reference signal (SRS) in the uplink, also known as SRS for positioning or positioning SRS.

[0046] The positioning function based on the NR system mainly involves three parts:

[0047] 1) Terminal equipment (i.e., UE)

[0048] 2) Multiple TRPs

[0049] Multiple TRPs around the terminal device participate in cellular positioning;

[0050] A base station may be a TRP;

[0051] A base station may have multiple TRPs.

[0052] 3) Location server

[0053] The location server is responsible for the entire location process;

[0054] Location servers may include location management functions (LMF), or be referred to as location devices.

[0055] Downlink-based location methods can be further divided into the following two categories:

[0056] 1) Terminal Equipment-Assisted Positioning Method

[0057] The terminal equipment is responsible for positioning-related measurements;

[0058] Network devices calculate location information based on measurement data reported by terminal devices.

[0059] 2) User Equipment-based (UE) positioning method

[0060] The terminal device performs positioning-related measurements and calculates location information based on the measurement data.

[0061] As an example, the downlink-based UE-assisted positioning method shown in Figure 6 may include some or all of the following steps in the positioning process.

[0062] Step 1.1: The location server notifies the TRP of relevant configurations. This configuration may include PRS configuration information and / or the types of measurement data that the terminal device needs to report.

[0063] Step 1.2: TRP sends a positioning signal PRS.

[0064] Step 1.3: The terminal device receives the positioning signal (PRS) and measures it. The measurement data obtained by the terminal device will vary depending on the positioning method used.

[0065] Step 1.4: The terminal device sends the measurement data back to the positioning server. For example, the terminal device can send the measurement data back to the positioning server via a base station.

[0066] Step 1.5: The positioning server calculates location-related information based on the measurement data.

[0067] For the UE-based positioning method, in step 4 above, the terminal device can directly calculate the location-related information based on the measurement data, without reporting the measurement data to the positioning server; instead, the positioning server performs the location calculation. In the UE-based positioning method, the terminal device needs to know the location information corresponding to the TRP; therefore, the network device needs to notify the terminal device of the location information corresponding to the TRP in advance.

[0068] For example, as shown in Figure 7, the uplink-based positioning method may include some or all of the following steps in the positioning process.

[0069] Step 2.1: The location server notifies TRP of relevant configurations.

[0070] Step 2.2: The base station sends relevant signaling to the terminal device.

[0071] Step 2.3: The terminal device sends an uplink signal, such as SRS, based on the received signaling.

[0072] Step 2.4: TRP measures the SRS and sends the measurement results to the positioning server.

[0073] Step 2.5: The location server calculates location-related information.

[0074] AI / ML-based positioning technology

[0075] Localization methods that combine AI / ML with positioning technology can further improve positioning accuracy. Among these, AI / ML-based localization methods include the following possible use cases:

[0076] Case 1: UE-based localization method using AI / ML models deployed on the UE side.

[0077] Case 2a: UE-assisted / LMF-based localization method with AI / ML model deployed on the UE side.

[0078] Case 2b: UE-assisted / LMF-based localization method with AI / ML model deployed on the LMF side.

[0079] Case 3a: NG-RAN node-assisted localization method for deploying AI / ML models on the gNB side.

[0080] Case 3b: NG-RAN node-assisted localization method for deploying AI / ML models on the LMF side.

[0081] In the above possible cases, the training dataset used to train the AI / ML model may include, for example, the following:

[0082] Part A includes channel measurements, quality indicators of channel measurements, and timestamps of channel measurements; and,

[0083] Part B includes the label, the label's quality indicator, and the label's timestamp.

[0084] In this model training, both part A and part B are used. For example, part A includes channel measurement data, quality indication information characterizing the quality of the channel measurement data, and corresponding timestamps. Part B includes labels, quality indication information characterizing the quality of the labels, and corresponding timestamps. Labels are typically used to represent the target value of the task the model needs to achieve, thereby building the model by learning features from historical data and corresponding labels. In this embodiment, the labels used by the positioning model during training can be the location of the terminal device or intermediate data used to calculate the location of the terminal device (the calculation process can employ the aforementioned algorithms). It is understood that during model training, part A can correspond to the model's input, and part B can correspond to the model's output. The model can directly output the location of the terminal device or output relevant intermediate data, which the corresponding device then uses to calculate the location of the terminal device. The first data mentioned below includes some or all of the information in part A, and the second data includes all or part of the information in part B. Furthermore, the channel measurement described in this embodiment can refer to measurements related to the positioning of the terminal device, such as measurements of reference signals.

[0085] For the different cases mentioned above, the devices (or entities) used to determine (or generate) the first and second data can be the same or different. The devices used to determine the first and second data for different cases can be as shown in Table 1. Specifically, for case 1, the first data is determined by the terminal device or the positioning reference unit (PRU), and the second data is determined by the PRU, the terminal device, or the LMF; for case 2a, the first data is determined by the terminal device or the PRU, and the second data is determined by the PRU, the terminal device, or the LMF; for case 2b, the first data is determined by the terminal device or the PRU, and the second data is determined by the PRU, the terminal device, or the LMF; for case 3a, the first data is determined by the TRP or the base station, and the second data is determined by the LMF; for case 3b, the first data is determined by the TRP or the base station, and the second data is determined by the PRU, the terminal device, or the LMF.

[0086] Table 1

[0087] If the training data sample includes first data and second data, since the devices that generated the first and second data may be different, there is currently no solution for how to use the first and second data for model training. Therefore, embodiments of this application propose to ensure the effectiveness of model training by associating (or matching) the first and second data.

[0088] The embodiments of this application will be described in detail below with reference to Figure 8.

[0089] Figure 8 is a flowchart illustrating a wireless communication method provided in an embodiment of this application. The method 800 shown in Figure 8 can be executed by a terminal device and a network device. The terminal device can be, for example, the terminal device 120 shown in Figure 1, and the network device can be, for example, the network device 110 shown in Figure 1.

[0090] Referring to Figure 8, in step 810, the first data or the second data is determined.

[0091] The first data and the second data are used for the positioning of the terminal device. Optionally, the first data and the second data can be determined by different devices. In this embodiment, the effectiveness of positioning can be improved by associating the first data and the second data. For example, in a model-based positioning method, the first data and the second data are used to train the model, which is used for the positioning of the terminal device. This model is, for example, the aforementioned AI / ML model.

[0092] It should be noted that the embodiments of this application do not limit the device performing step 810. For example, the first data mentioned in step 810 can be determined by a first device or a second device; and / or, the second data in step 810 can be determined by a first device, a second device, or a third device. As an example, the first device includes a terminal device or a PRU; the second device includes a base station or a Transmitter / Receiver Point (TRP); and the third device includes an LMF.

[0093] As an example, for cases 3a and 3b above, step 810 may include: the second device determining the first data; or, the first device determining the second data; or, the third device determining the second data. For example, as shown in FIG9, FIG9(a) illustrates the first case of case 3b above, i.e., the second device determines both the first and second data; FIG9(b) and FIG9(c) illustrate the second and third cases of case 3b, in which the second device determines the first data and the third device determines the second data. The difference between FIG9(b) and FIG9(c) is that, in the second case shown in FIG9(b), the third device determines the second data using positioning-related measurement data obtained from the second device, while in the third case shown in FIG9(c), the third device determines the second data using positioning-related measurement data obtained from the first device. For example, case 3a also includes two cases, which can be referred to in Figure 9(b) and Figure 9(c). However, the difference between case 3a and case 3b is that the content of the second data involved is different, which will be described in detail later.

[0094] As an example, for cases 1, 2a, and 2b above, step 810 may include: a first device determining first data; or a third device determining second data. For example, as shown in FIG10, FIG10(a) illustrates the first case of cases 1, 2a, and 2b above, i.e., the first device determines the first data and the third device determines the second data; FIG10(b) illustrates the second case of cases 1, 2a, and 2b above, i.e., the first device determines the first data and the third device determines the second data. The difference between FIG10(a) and FIG10(b) is that, in the first case shown in FIG10(a), the third device determines the second data using positioning-related measurement data obtained from the first device, while in the second case shown in FIG10(b), the third device determines the second data using positioning-related measurement data obtained from the second device.

[0095] The first and second data are described in detail below.

[0096] In one implementation, the first data is related to positioning-related measurement data; the second data is related to the measurement result of the desired reference signal. For example, the second data may include the location information of the terminal device and / or intermediate data used to calculate the location information.

[0097] As an example, the first data may include one or more of the following: time information associated with the first data; identification information associated with the first data; time measurement data; power (reference signal received power (RSRP) or reference signal received quality (RSRQ)) measurement data; phase measurement data; uplink angle of arrival measurement data; line-of-sight (LoS) measurement data; non-line-of-sight (NLoS) measurement data; information on the measurement beam; resource type corresponding to the reference signal (e.g., periodic or semi-static); resource index corresponding to the reference signal; quality indication information for the time measurement data; quality indication information for the power measurement data; quality indication information for the phase measurement data; quality indication information for the uplink angle of arrival measurement data; quality indication information for the LoS measurement data; and quality indication information for the NLoS measurement data.

[0098] The content of the second data may vary depending on the specific circumstances. For example, in cases 1, 2b, and 3b mentioned above, the second data may include one or more of the following: time information associated with the second data; identification information associated with the second data; the location result of the terminal device; and quality indication information of the location result. In other words, the label in the second data can be the location result of the terminal device (e.g., the location information of the terminal device). In this case, the trained model can directly output the location information of the terminal device based on the measurement data during inference.

[0099] For example, in cases 2a and 3a mentioned above, the second data may include one or more of the following: time information associated with the second data; identification information associated with the second data; time measurement results; power measurement results; phase measurement results; uplink angle of arrival measurement data; Loss of Speed ​​(LoS) measurement results; NLoS measurement results; quality indication information for time measurement results; quality indication information for power measurement results; quality indication information for phase measurement results; quality indication information for uplink angle of arrival measurement results; quality indication information for LosS measurement results; and quality indication information for NLoS measurement results. In other words, the labels in the second data can be intermediate data (e.g., time measurement results, power measurement results, phase measurement results, LosS measurement results, NLoS measurement results) used to calculate the positioning result of the terminal device (e.g., the location information of the terminal device), and the positioning result of the terminal device can be calculated using this intermediate data. In this case, the trained model can output corresponding measurement results based on the measurement data during the inference process, and calculate the location information of the terminal device using a positioning algorithm.

[0100] In this embodiment, both the first data and the second data may include their respective associated time information, and / or both the first data and the second data may include their respective associated identification information. In this embodiment, the association between the first data and the second data is established through the time information and / or the identification information. How to establish the association between the first data and the second data will be described in detail later. Furthermore, in one implementation, the first data may include positioning-related measurement data; correspondingly, the second data includes positioning-related measurement results. For example, if the first data includes time measurement data, the second data may include time measurement results; if the first data includes power measurement data, the second data may include power measurement results; if the first data includes phase measurement data, the second data may include phase measurement results; if the first data includes LoS measurement data, the second data may include LoS measurement results; if the first data includes NLoS measurement data, the second data may include NLoS measurement results. Furthermore, the first data may also include quality indication information for various types of measurement data (e.g., quality indication information for time measurement data, power measurement data, phase measurement data, LosS measurement data, and NLoS measurement data). Similarly, the second data may also include quality indication information for various types of measurement results (e.g., quality indication information for time measurement results, power measurement results, phase measurement results, LosS measurement results, and NLoS measurement results). Alternatively, in another implementation, the first data may include positioning-related measurement data and quality indication information for various types of measurement data; correspondingly, the second data may include the location information of the terminal device and quality indication information for that location information.

[0101] The time information mentioned above can be represented in one or more of the following ways: timestamp (NR-TimeStamp); system frame number (SFN) time (sfn-time); universal coordinated time (UTC or UTC-time); slot index; symbol index; measurement time of the reference signal.

[0102] The identification information mentioned above may include one or more of the following: an identity (ID) identifier (e.g., a sequence); a resource index of a first reference signal; a resource index of a second reference signal; and a terminal device identifier (UE ID).

[0103] The reference signal described in this embodiment may include a first reference signal (e.g., an SRS for positioning) and / or a second reference signal (e.g., a PRS). As shown in Figures 9 and 10, the first reference signal is transmitted by a first device and measured by a second device, and the second reference signal is transmitted by a second device and measured by a first device.

[0104] In one implementation, the first data is determined based on measurement data of a first reference signal or a second reference signal; and / or, the second data is determined based on measurement data of the first reference signal or the second reference signal. For example, as shown in FIG9(a), the first data is determined by a second device based on measurement data of the first reference signal, and the second data is determined by the first device based on measurement data of the second reference signal. As another example, as shown in FIG9(b), the first data is determined by a second device based on measurement data of the first reference signal, and the second data is determined by a third device based on measurement data of the first reference signal, wherein the second device sends measurement data of the first reference signal to the third device. As yet another example, as shown in FIG9(c), the first data is determined by a second device based on measurement data of the first reference signal, and the second data is determined by a third device based on measurement data of the second reference signal, wherein the first device sends measurement data of the second reference signal to the third device. For example, as shown in Figure 10(a), the first data is determined by the first device based on the measurement data of the second reference signal, and the second data is determined by the third device based on the measurement data of the second reference signal, wherein the first device sends the measurement data of the second reference signal to the third device. For example, as shown in Figure 10(b), the first data is determined by the first device based on the measurement data of the second reference signal, and the second data is determined by the third device based on the measurement data of the first reference signal, wherein the second device sends the measurement data of the first reference signal to the third device.

[0105] To associate the first data with the second data, in one implementation, the first data includes time information associated with (or corresponding to) the first data, and the second data includes time information associated with (or corresponding to) the second data, and the time information associated with the first data is the same as the time information associated with the second data. That is, if the time information associated with a certain first data and a certain second data is the same, it indicates that the first data is associated with the second data. The time information associated with the first data and the time information associated with the second data are determined, for example, based on the following times: the transmission time of the second reference signal; or, the reception time of the second reference signal; or, the transmission time of the first reference signal; or, the reception time of the first reference signal. As an example, the time information carried in the first data and the second data can both be the transmission time of the second reference signal, or both be the reception time of the second reference signal, or both be the transmission time of the first reference signal, or both be the reception time of the first reference signal.

[0106] In another implementation, the first data includes time information associated with the first data, and the second data includes time information associated with the second data, and the time information associated with the first data is different from the time information associated with the second data. For example, the time interval between the time information associated with the first data and the time information associated with the second data is less than a predetermined time threshold. That is, if the time interval between the time information of a certain first data and a certain second data is less than the predetermined time threshold, it indicates that the first data is associated with the second data. Another example is that the time interval between the time information associated with the first data and the time information associated with the second data is located in the same time unit. That is, if the time interval between the time information of a certain first data and a certain second data is located in the same time unit (e.g., time slot, symbol, mini-time slot), it indicates that the first data is associated with the second data.

[0107] The following describes the situations where the first and second data are associated with different time information, based on the above cases.

[0108] For example, in the first case 3b shown in Figure 9(a), the first data is determined by the second device based on the measurement data of the first reference signal, and the second data is determined by the first device based on the measurement data of the second reference signal. In one implementation, the time information associated with the first data is determined based on the reception time of the first reference signal (i.e., the time when the second device receives the first reference signal), for example, the time information associated with the first data is the time when the TRP or the base station receives the SRS; the time information associated with the second data is determined based on the transmission time of the first reference signal (i.e., the time when the first device transmits the first reference signal), for example, the time information associated with the second data is the time when the UE or PRU transmits the SRS. Alternatively, in another implementation, the time information associated with the first data is determined based on the transmission time of the second reference signal (i.e., the time when the second device transmits the second reference signal), for example, the time information associated with the first data is the time when the TRP or the base station transmits the PRS; the time information associated with the second data is determined based on the reception time of the second reference signal (i.e., the time when the first device receives the second reference signal), for example, the time information associated with the second data is the time when the UE or PRU receives the PRS.

[0109] Optionally, the time interval between the reception time and the transmission time of the first reference signal is less than a first time threshold, or they are located in the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first data and second data is less than the first time threshold or they are located in the same time unit. Optionally, the time interval between the transmission time and the reception time of the second reference signal is less than a second time threshold, or they are located in the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first data and second data is less than the second time threshold or they are located in the same time unit. Here, the time unit includes, but is not limited to, time slots, symbols, and mini-time slots.

[0110] For example, in the second case of case 3b shown in Figure 9(b) or the first case of case 3a, the first data is determined by the second device based on the measurement data of the first reference signal, and the second data is determined by the third device based on the measurement data of the first reference signal. In one implementation, the time information associated with the first data is determined based on the reception time of the first reference signal (i.e., the time when the second device receives the first reference signal), for example, the time information associated with the first data is the time when the TRP or the base station receives the SRS; the time information associated with the second data is determined based on the time when the second device measures the first reference signal (i.e., the measurement time of the first reference signal), for example, the time information associated with the second data is the time when the TRP or the base station measures the SRS. In another implementation, the time information associated with the first data is determined based on the reception time of the first reference signal (i.e., the time when the second device receives the first reference signal), for example, the time information associated with the first data is the time when the TRP or the base station receives the SRS; the time information associated with the second data is determined based on the time when the third device receives the measurement data of the first reference signal, for example, the time when the LMF receives the SRS measurement data sent by the TRP or the base station.

[0111] Optionally, the time interval between the reception time of the first reference signal and the time when the second device measures the first reference signal is less than a seventh time interval, or they are located in the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first data and second data is less than the seventh time threshold or they are located in the same time unit. Optionally, the time interval between the reception time of the first reference signal and the time when the third device receives the measurement data of the first reference signal is less than an eighth time interval, or they are located in the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first data and second data is less than the eighth time threshold or they are located in the same time unit. Here, the time unit includes, but is not limited to, time slots, symbols, and mini-time slots.

[0112] For example, in the third case of case 3b shown in Figure 9(c) or the second case of case 3a, the first data is determined by the second device based on the measurement data of the first reference signal, and the second data is determined by the third device based on the measurement data of the second reference signal. In one implementation, the time information associated with the first data is determined based on the reception time of the first reference signal (i.e., the time when the second device receives the first reference signal), for example, the time information associated with the first data is the time when the TRP or the base station receives the SRS; the time information associated with the second data is determined based on the reception time of the second reference signal (i.e., the time when the first device receives the second reference signal), for example, the time information associated with the second data is the time when the UE or PRU receives the PRS. In another implementation, the time information associated with the first data is determined based on the reception time of the first reference signal (i.e., the time when the second device receives the first reference signal), for example, the time information associated with the first data is the time when the TRP or the base station receives the SRS; the time information associated with the second data is determined based on the time when the third device receives the measurement data of the second reference signal, for example, the time information associated with the second data is the time when the LMF receives the SRS measurement data sent by the UE or PRU.

[0113] Optionally, the time interval between the reception time of the first reference signal and the reception time of the second reference signal is less than a third time threshold, or they are located in the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first and second data is less than the third time threshold or they are located in the same time unit. Optionally, the time interval between the reception time of the first reference signal and the time when the third device receives the measurement data of the second reference signal is less than a fourth time threshold, or they are located in the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first and second data is less than the fourth time threshold or they are located in the same time unit.

[0114] For example, in the first case of cases 1, 2a, and 2b shown in Figure 10(a), the first data is determined by the first device based on the measurement data of the second reference signal, and the second data is determined by the third device based on the measurement data of the second reference signal. In one implementation, the timing information associated with the first data determines the reception time of the second reference signal (i.e., the time when the first device receives the second reference signal). For example, the timing information associated with the first data is the time when the UE or PRU receives the PRS. The timing information associated with the second data is determined based on the time when the third device receives the measurement data of the second reference signal. For example, the timing information associated with the second data is the time when the LMF receives the SRS measurement data sent by the UE or PRU.

[0115] Optionally, the time interval between the reception time of the second reference signal and the time when the third device receives the measurement data of the second reference signal is less than a ninth threshold, or they are within the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first and second data is less than the ninth time threshold or they are within the same time unit. Optionally, the time interval between the reception time of the second reference signal and the time when the third device receives the measurement data of the second reference signal is less than a tenth threshold, or they are within the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first and second data is less than the tenth time threshold or they are within the same time unit.

[0116] For example, in the second case of cases 1, 2a, and 2b shown in Figure 10(b), the first data is determined by the first device based on the measurement data of the second reference signal, and the second data is determined by the third device based on the measurement data of the first reference signal. In one implementation, the time information associated with the first data is determined based on the reception time of the second reference signal (i.e., the time when the first device receives the second reference signal), for example, the time information associated with the first data is the time when the UE or PRU receives the PRS; the time information associated with the second data is determined based on the transmission time of the first reference signal (i.e., the time when the first device transmits the first reference signal), for example, the time information associated with the second data is the time when the UE or PRU transmits the SRS. In another implementation, the time information associated with the first data is determined based on the reception time of the second reference signal (i.e., the time when the first device receives the second reference signal); the time information associated with the second data is determined based on the time when the third device receives the measurement data of the first reference signal, for example, the time information associated with the second data is the time when the LMF receives the SRS measurement data transmitted by the UE or PRU.

[0117] Optionally, the time interval between the reception time of the second reference signal and the transmission time of the first reference signal is less than a fifth time threshold, or they are within the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first and second data is less than the fifth time threshold or they are within the same time unit. Optionally, the time interval between the reception time of the second reference signal and the time when the third device receives the measurement data of the first reference signal is less than a sixth time threshold, or they are within the same time unit. In this case, the time interval between the times indicated by the time information carried in the associated first and second data is less than the sixth time threshold or they are within the same time unit.

[0118] Besides the method described above of associating the first data and the second data using time information from the first and second data, other implementations can also associate the first data and the second data using identification information from the first and second data. For example, the first data includes identification information associated with the first data, the second data includes identification information associated with the second data, and the identification information associated with the first data is the same as the identification information associated with the second data. That is, the first data and the second data are associated with the same identification information. This identification information includes, for example, ID (e.g., sequence), SRS resource index, PRS resource index, and UE ID.

[0119] Furthermore, when the devices used to determine the origin of the first data and the second data are the same (i.e., the first data and the second data are generated by the same entity), the first data and the second data can also be associated using the timestamp and / or identification information described in the embodiments of this application. That is, the time information carried in the associated first data and the second data is the same or differs by less than a predetermined time interval, and / or the identification information carried in the associated first data and the second data is the same.

[0120] The embodiments of this application are described in more detail below with specific examples. It should be noted that the following examples are merely to help those skilled in the art understand the embodiments of this application, and are not intended to limit the embodiments of this application to the specific numerical values ​​or scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or variations based on the given examples, and such modifications or variations also fall within the scope of the embodiments of this application.

[0121] Example 1

[0122] Example 1 applies to the first case of case 3b, as shown in Figure 9(a), where the second device determines the first data based on the first reference signal, and the first device determines the second data based on the second reference signal. The first reference signal is the SRS sent by the first device (e.g., a terminal device) to the second device (e.g., a network device), and the second reference signal is the PRS received by the terminal device. The first data includes, for example, one or more of the following: a timestamp associated with (or corresponding to) the first data; identification information associated with the first data; time measurement data; power measurement data; phase measurement data; uplink angle of arrival measurement data; Loss measurement data; NLoS measurement data; information of the measurement beam; resource type corresponding to the SRS; resource index corresponding to the SRS; and quality indication information for the above-mentioned measurement data. The second data includes, for example, one or more of the following: a timestamp associated with (or corresponding to) the second data; identification information associated with the second data; the location of the terminal device; and quality indication information for that location.

[0123] The first and second data are related, for example, they can be related through one or more of the following methods in combination:

[0124] In the first method, the timestamp corresponding to the first data is the timestamp corresponding to the time when the second device receives the first reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the first device sends the first reference signal. That is, the timestamp corresponding to the first data is the timestamp corresponding to the time when the TRP / gNB receives the SRS, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the UE / PRU sends the SRS.

[0125] Specifically, the interval between the timestamp corresponding to the time when the second device receives the first reference signal and the timestamp corresponding to the time when the first device sends the first reference signal is less than a predetermined time interval; or, the timestamp corresponding to the time when the second device receives the first reference signal and the timestamp corresponding to the time when the first device sends the first reference signal are in the same time unit. This time unit can be a time slot, a symbol, a mini-time slot, etc.

[0126] In the second method, the timestamp corresponding to the first data is the timestamp corresponding to the time when the second device sends the second reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the first device receives the second reference signal. That is, the timestamp corresponding to the first data is the timestamp corresponding to the time when the TRP / gNB sends the PRS, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the UE / PRU receives the PRS.

[0127] Specifically, the interval between the timestamp corresponding to the time when the second device transmits the second reference signal and the timestamp corresponding to the time when the first device receives the second reference signal is less than a predetermined time interval; or, the timestamp corresponding to the time when the second device transmits the second reference signal and the time when the first device receives the second reference signal are in the same time unit. This time unit can be a time slot, a symbol, a mini-time slot, etc.

[0128] In the third approach, the first data and the second data are associated with the same timestamp. For example, both the first data and the second data are associated with the timestamp corresponding to the transmission time of the first reference signal, or both are associated with the timestamp corresponding to the reception time of the first reference signal, or both are associated with the timestamp corresponding to the transmission time of the second reference signal, or both are associated with the timestamp corresponding to the reception time of the second reference signal.

[0129] In the fourth approach, the first and second data are associated with the same identification information, such as ID, SRS resource index, PRSRS resource index, UE ID, etc. The associated first and second devices have the same identification information, such as the same ID, the same SRS resource index, the same PRS resource index, or the same UE ID.

[0130] Example 2

[0131] Example 2 applies to the second and third cases of case 3b, where the first data is generated by the second device and the second data is generated by the third device. In the second case, the first data is the measurement data obtained by the second device from the first reference signal, and the second data is generated by the third device based on the measurement data obtained by the second device from the SRS measurement, as shown in Figure 9(b). In the third case, the first data is the measurement data obtained by the second device from the first reference signal, and the second data is generated by the third device based on the measurement data obtained by the first device from the second reference signal, as shown in Figure 9(c).

[0132] In the second scenario, the measurement data from the second device is obtained based on the first reference signal, and the second data generated by the third device is also calculated based on the measurement data obtained by the second device from the first reference signal. The first and second data are correlated, for example, through one or more combinations of the following methods:

[0133] In the first approach, the first data and the second data are associated with the same timestamp. For example, both the first data and the second data are associated with the timestamp corresponding to the transmission time of the first reference signal, or both are associated with the timestamp corresponding to the reception time of the first reference signal.

[0134] In the second approach, the first data and the second data are associated with different timestamps, and the time interval between the different timestamps is less than a predetermined time interval. For example, the timestamp corresponding to the first data is the timestamp corresponding to the reception time of the first reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the third device receives the measurement data from the second device, or the timestamp corresponding to the second data is the timestamp corresponding to the measurement time when the second device measures the first reference signal.

[0135] In the third approach, the first and second data are associated with the same identification information, such as ID, SRS resource index, PRS resource index, UE ID, etc. The associated first and second devices have the same identification information, such as the same ID, the same SRS resource index, the same PRS resource index, or the same UE ID.

[0136] In the third case, the first data is generated based on the first reference signal, and the second data is generated by the third device based on measurement data obtained by the first device from the second reference signal. The first data and the second data are correlated, for example, through one or more combinations of the following methods:

[0137] In the first method, the timestamp corresponding to the first data is the timestamp corresponding to the time when the second device receives the first reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the first device receives the second reference signal. That is, the timestamp corresponding to the first data is the timestamp corresponding to the time when the TRP / gNB receives the SRS, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the UE / PRU receives the PRS.

[0138] Specifically, the interval between the timestamp corresponding to the time when the second device receives the first reference signal and the timestamp corresponding to the time when the first device receives the second reference signal is less than a predetermined time interval; or, the timestamp corresponding to the time when the second device receives the first reference signal and the timestamp corresponding to the time when the first device receives the second reference signal are in the same time unit. This time unit can be a time slot, a symbol, a mini-time slot, etc.

[0139] In the second method, the timestamp corresponding to the first data is the timestamp corresponding to the time when the second device receives the first reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the third device receives the measurement data sent by the first device. That is, the timestamp corresponding to the first data is the timestamp corresponding to the time when the TRP / gNB receives the SRS, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the third device receives the measurement data after the UE / PRU obtains the measurement data according to the PRS.

[0140] Specifically, the interval between the timestamp corresponding to the time when the second device receives the first reference signal and the timestamp corresponding to the time when the third device receives the measurement data sent by the first device is less than a predetermined time interval; or, the timestamp corresponding to the time when the second device receives the first reference signal and the timestamp corresponding to the time when the third device receives the measurement data sent by the first device are in the same time unit. This time unit can be a time slot, a symbol, a mini-time slot, etc.

[0141] In the third approach, the first data and the second data are associated with the same timestamp. For example, both the first data and the second data are associated with the timestamp corresponding to the transmission time of the first reference signal, or both are associated with the timestamp corresponding to the reception time of the first reference signal, or both are associated with the timestamp corresponding to the transmission time of the second reference signal, or both are associated with the timestamp corresponding to the reception time of the second reference signal.

[0142] In the fourth approach, the first and second data are associated with the same identification information, such as ID, SRS resource index, PRS resource index, UE ID, etc. The associated first and second devices have the same identification information, such as the same ID, the same SRS resource index, the same PRS resource index, or the same UE ID.

[0143] Example 3

[0144] Example 3 applies to cases 1, 2a, or 2b, where the first data is generated by the first device and the second data is generated by the third device. Specifically, it can include two scenarios: In the first scenario, the third device uses the measurement data sent by the first device and calculates the location of the terminal device using a conventional method as the tag, i.e., the second data, as shown in Figure 10(a). In the second scenario, the third device uses the measurement data sent by the second device and calculates the location of the terminal device using a conventional method as the tag, i.e., the second data, as shown in Figure 10(b).

[0145] In the first scenario, the measurement data from the first device is generated based on the second reference signal, and the second data generated by the third device is also calculated based on the measurement data obtained by the first device from the second reference signal. The first and second data are correlated, for example, through one or more combinations of the following methods:

[0146] In the first approach, the first data and the second data are associated with the same timestamp. For example, both the first data and the second data are associated with the timestamp corresponding to the transmission time of the second reference signal, or both are associated with the timestamp corresponding to the reception time of the second reference signal.

[0147] In the second approach, the first data and the second data are associated with different timestamps, but the time interval between the different timestamps is less than a predetermined time interval. For example, the timestamp corresponding to the first data is the timestamp corresponding to the reception time of the second reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the third device receives the measurement data from the first device.

[0148] In the third approach, the first and second data are associated with the same identification information, such as ID, SRS resource index, PRS resource index, UE ID, etc. The associated first and second devices have the same identification information, such as the same ID, the same SRS resource index, the same PRS resource index, or the same UE ID.

[0149] In the second scenario, the measurement data from the first device is generated based on the second reference signal, and the second data generated by the third device is calculated based on the measurement data obtained by the second device from the first reference signal. The first and second data are correlated, for example, through one or more combinations of the following methods:

[0150] In the first method, the timestamp corresponding to the first data is the timestamp corresponding to the time when the first device receives the second reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the first device sends the first reference signal. That is, the timestamp corresponding to the first data is the timestamp corresponding to the time when the UE / PRU receives the PRS, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the UE / PRU sends the SRS.

[0151] Specifically, the interval between the timestamp corresponding to the time when the first device receives the second reference signal and the timestamp corresponding to the time when the first device sends the first reference signal is less than a predetermined time interval; or, the timestamp corresponding to the time when the first device receives the second reference signal and the timestamp corresponding to the time when the first device sends the first reference signal are in the same time unit. This time unit can be a time slot, a symbol, a mini-time slot, etc.

[0152] In the second method, the timestamp corresponding to the first data is the timestamp corresponding to the time when the first device receives the second reference signal, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the third device receives the measurement data sent by the second device. That is, the timestamp corresponding to the first data is the timestamp corresponding to the time when the UE / PRU receives the PRS, and the timestamp corresponding to the second data is the timestamp corresponding to the time when the third device receives the measurement data after the TRP / gNB obtains the measurement data according to the SRS.

[0153] Specifically, the interval between the timestamp corresponding to the time when the first device receives the second reference signal and the timestamp corresponding to the time when the third device receives the measurement data from the second device is less than a predetermined time interval; or, the timestamp corresponding to the time when the first device receives the second reference signal and the timestamp corresponding to the time when the third device receives the measurement data from the second device are in the same time unit. This time unit can be a time slot, a symbol, a mini-time slot, etc.

[0154] In the third approach, the first data and the second data are associated with the same timestamp. For example, both the first data and the second data are associated with the timestamp corresponding to the transmission time of the first reference signal, or both are associated with the timestamp corresponding to the reception time of the first reference signal, or both are associated with the timestamp corresponding to the transmission time of the second reference signal, or both are associated with the timestamp corresponding to the reception time of the second reference signal.

[0155] In the fourth approach, the first and second data are associated with the same identification information, such as ID, SRS resource index, PRS resource index, UE ID, etc. The associated first and second devices have the same identification information, such as the same ID, the same SRS resource index, the same PRS resource index, or the same UE ID.

[0156] Example 4

[0157] Example 4 applies to case 3a. The association method between the first and second data in Example 4 can be referenced from the descriptions of case 3b in Examples 1 and 2. However, it should be noted that the content of the second data differs between case 3a and case 3b. In case 3a, the second data may include intermediate data used to calculate the location information of the terminal device, such as one or more of the following: timestamp corresponding to the second data, identification information associated with the second data, time measurement results, power measurement results, phase measurement results, LoS measurement results, NLoS measurement results, quality indication information for time measurement results, quality indication information for power measurement results, quality indication information for uplink angle of arrival measurement results, quality indication information for phase measurement results, quality indication information for LoS measurement results, and quality indication information for NLoS measurement results. In case 3b, the second data may include the timestamp associated with the second data; the identification information associated with the second data; the location of the terminal device; and quality indication information for that location.
