[0102] Before introducing the positioning method provided by an embodiment of the present application, the communication system to which the embodiment of the present application is applicable will be introduced first.

[0103] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example, a universal mobile telecommunications system (UMTS), a wireless local area network (WLAN), an enhanced mobile broadband (eMBB) system, an ultra-reliable low-latency communications (URLLC) system, a machine type communication (MTC) system, a massive machine type communications (mMTC) system, an enhance machine type communication (eMTC) system, an internet of things (IoT) communication system, a narrow band internet of things (NB-IoT) system, a short-range wireless communication system (such as a sidelink, wireless fidelity (Wi-Fi), Bluetooth, or the like), a wired network, a vehicle to everything (V2X) communication system, a device-to-device (D2D) communication system, augmented reality (AR), virtual reality (VR), a vehicle networking communication system, a 4th generation (4G) mobile communication system (such as a long term evolution (LTE) system), an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a worldwide interoperability for microwave access (WiMAX) communication system, a 5th generation (5G) mobile communication system (such as a new radio (NR) system), a future communication system (such as a 6th generation (6G) mobile communication system), or other similar communication systems, and the like, without limitation.It should be understood that the system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0104] Figure 1 An exemplary structure of a communication system to which the embodiments of the present application are applicable is shown in a schematic diagram. Optionally, the communication system can also be referred to as a positioning system, without limitation. As shown in the figure, the communication system can include a user equipment (UE) and an operator network part. The communication system can also include an application function (AF) network element and a location services (LCS) client. Figure 1

[0105] The UE can be a user-side device with wireless transceiving function. The UE can also be referred to as a terminal device, a terminal apparatus, a terminal, an access station, a UE station, a remote station, a wireless communication device, or a user apparatus, etc. The terminal device can be used to connect people, things, machines, etc., and can be widely used in various scenarios, such as terminal devices in scenarios including but not limited to cellular communication, D2D, V2X, machine-to-machine / machine-type communications (M2M / MTC), IoT, virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, unmanned aerial vehicle, robot, etc. For example, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiving function, a VR terminal, an AR terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a smart speaker in IoT network, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, or a wireless terminal device in smart home, etc.

[0106] ​By way of example and without limitation, the terminal device in embodiments of the present application can also be a wearable device. The wearable device can also be referred to as a smart wearable device, a smart wearable device, or the like. It is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. The various terminal devices described above can be considered as vehicle-mounted terminal devices if they are located on a vehicle (e.g., placed inside or installed inside the vehicle), for example, on-board units (OBU). The terminal device of the present application can also be an on-board module, an on-board module, an on-board component, an on-board chip, or an on-board unit built into a vehicle as one or more components or units. The vehicle can implement the method of the present application through the built-in on-board module, on-board module, on-board component, on-board chip, or on-board unit.

[0107] It should be noted that the embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0108] The operator network can include, but is not limited to, one or more of the following network elements: location management function network element, unified data management network element, access management function network element, network exposure function, positioning management function network element, gateway mobile location center, and access network (AN) and the like. Among the above operator network, except for the access network part, the part can be referred to as the core network (CN) part.

[0109] Among them, the location management function network element, also known as the positioning server, is mainly responsible for selecting the positioning method, triggering the positioning measurement process, obtaining the measurement results from the base station or the terminal, performing the location calculation based on the measurement results, and feeding back the calculation results to the access management function network element or the gateway mobile location center. In the 5G communication system, the location management function network element can be a location management function (LMF) network element. In future communication systems, the location management function network element can also have other names, which are not limited.

[0110] An access management function network element, responsible for access control and mobility management of terminal equipment accessing the operator network, such as mobile state management, allocation of user temporary identity, authentication and authorization, etc. In the 5G communication system, the access management function network element can be an access and mobility management function (AMF) network element. In future communication systems, the access management function network element can also have other names, which are not limited. Exemplarily, for positioning, the AMF network element is mainly responsible for selecting the LMF network element, triggering the LCS positioning process, and responsible for message forwarding and transparent transmission of various interfaces, etc.

[0111] A unified data management network element, responsible for generating authentication credentials, user identity processing (such as storing and managing user permanent identity, etc.), subscription data management, etc. In the 5G communication system, the unified data management network element can be a unified data management (UDM) network element. In future communication systems, the unified data management network element can also have other names, which are not limited. Exemplarily, for positioning, the UDM network element can judge whether the UE is allowed to be positioned, and feed back the judgment result to the AMF network element where the user (or gateway mobile location center, or network exposure function network element) is located.

[0112] A network exposure function network element, mainly responsible for the comprehensive capability exposure of the 5G network, which includes positioning capability. In the 5G communication system, the network exposure function network element can be a network exposure function (NEF) network element. In future communication systems, the network exposure function network element can also have other names, which are not limited. Exemplarily, for positioning, the NEF network element supports two processes. One process is: for coarse positioning (such as cell identity positioning), the NEF network element can go through a simplified process, i.e. skipping the gateway mobile location center, directly obtaining the cell where the UE is located from the UDM network element and the AMF network element, and feeding back the positioning result; the other process is: for fine positioning, the NEF network element needs to go through the whole process, i.e. sending a positioning request to the gateway mobile location center, and obtaining the positioning result from the gateway mobile location center.

[0113] Gateway mobile location center, mainly responsible for processing the positioning request of the LCS client and feeding back the result of the positioning. For example, the gateway mobile location center can authenticate and authorize the LCS client, obtain the authorization information of the user to be positioned and the AMF network element where the user is located through the UDM network element, and forward the positioning request to the corresponding AMF network element for processing. In the 5G communication system, the gateway mobile location center can be a gateway mobile location center (GMLC). In future communication systems, the gateway mobile location center can also have other names, which are not limited.

[0114] LCS client, mainly responsible for positioning upper-layer services, including but not limited to the following functions: map display, positioning result presentation, and historical position storage functions. For example, the network provides the positioning result, and the LCS client is responsible for the upper-layer application of the location service.

[0115] AF, mainly to transfer the demand of the application side to the network side, for example, quality of service (QoS) demand or user state event subscription, etc. The AF can be a third-party functional entity or an application service deployed by the operator, which is not limited. Exemplarily, for positioning, the function of the AF is similar to that of the LCS client, the difference is that the LCS client is only a positioning service application, and the AF is a comprehensive application platform, and the positioning service application is one aspect of it.

[0116] The AN includes an AN device. The AN device is configured to access a terminal device to a wireless network. The AN device, as a node in an access network, can also be referred to as an access network element, a base station, a radio access network (RAN) node (or device, or element), an access point (AP), a small tower, a network device, a network apparatus, etc. The RAN can be an access network in the 3rd Generation Partnership Project (3GPP), for example, a 4G, 5G, or future-oriented 6G network. The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above networks. The RAN device can also be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.

[0117] The RAN device can also be a module or unit that completes part of the function of the base station, for example, it can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Among them, one CU can be connected to one DU, or one CU can be connected to multiple DUs, which can save costs and facilitate network expansion. That is, the access network device can be composed of one CU and one or more DUs. The CU and the DU are connected through the F1 interface, and the CU and the core network are connected through the next generation (NG) interface. Optionally, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc.

[0118] In a possible implementation, the CU can complete functions of a radio resource control (RRC) layer and a PDCP layer of the base station, and can also complete a function of an SDAP layer; the DU can complete functions of an RLC layer and a MAC layer of the base station, and can also complete a function of a partial PHY layer or a complete PHY layer. For specific descriptions of the protocol layers, refer to related technical specifications of the 3rd generation partnership project (3GPP). The CU and the DU can be separately configured, or can also be included in a same network element, for example, a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). In different systems, the CU, the DU, or the RU can also have different names, but a person skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU (open DU), and the RU can also be referred to as an O-RU (open RU). Any of the CU (or CU-CP, CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of the software module and the hardware module. It can be understood that the base station can adopt a CU-DU separation architecture, or can not adopt the CU-DU separation architecture. The base station can adopt a CP-UP separation architecture, or can not adopt the CP-CP separation architecture.

[0119] It should be noted that embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0120] As described above, Figure 1 The network elements that can be involved in various embodiments of the present application are mainly introduced, Figure 1 The communication system shown in the figure can also involve other network elements. For example, the core network can include one or more of the following: a unified data repository (UDR) network element, a network slice selection function (NSSF) network element, or an authentication server function (AUSF) network element, and the like, Figure 1 not shown in the figure.

[0121] Figure 1The interface sequence numbers are Uu, LPP, NRPPa, N2, NL1, N8, N51, N52, N33, NL2, NL5, NL6, and Le. The meanings of these interface sequence numbers can be found in the 3GPP standard protocol, and are not limited herein.

[0122] It can be understood that, Figure 1 The illustrated network elements or functions can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). In one possible implementation, the network elements or functions described above can be implemented by one device, by multiple devices together, or by a functional module within a device, and are not limited in this regard. In addition, the embodiments of the present application do not limit the names of the network elements in the communication system. For example, in different communication systems of different standards, the network elements can have other names. For another example, when multiple network elements are integrated in the same physical device, the physical device can also have other names.

[0123] Next, the technical features related to the embodiments of the present application are introduced.

[0124] In the 3GPP standard, multiple positioning technologies are supported, including time of arrival (TOA) based positioning technology and time difference of arrival (TDOA) based positioning technology. TOA positioning determines the distance between a terminal device and a base station by measuring the time difference between the time when the base station sends a signal and the time when the terminal device receives the signal. TDOA positioning determines the position of a terminal device by measuring the transmission time delay difference between the terminal device and multiple base stations. According to the different measurement objects, TDOA positioning includes downlink time difference of arrival (DL-TDOA) positioning technology and uplink time difference of arrival (UL-TDOA) positioning technology.

[0125] Please refer to Figure 2 , for a schematic diagram of one principle of TDOA based positioning. Figure 2 Three base stations (denoted as base station 1, base station 2, and base station 3, respectively) are taken as an example. A terminal device sends a sounding reference signal (SRS), and accordingly, the base station 1, the base station 2, and the base station 3 receive the SRS. The three base stations measure the TOA of the SRS from the terminal device to themselves, and send the TOA to a positioning system, which calculates the position of the terminal device.

[0126] Please refer toFigure 3 This is a schematic diagram illustrating the principle of leaky cable positioning. Figure 3 In the middle, base station 1 and base station 2 are connected by a leaky cable ( Figure 3 (The example shown is a thick black line.) Additionally, [the connection is shown]. Figure 3 The example is taken in a tunnel, but it is not limited to this scenario. Because electromagnetic waves propagate along the leaky cable, two base stations can be used to locate the terminal device. Specifically, the terminal device sends SRS (…). Figure 3 (Not shown in the image), the SRS is transmitted to two base stations through a leaky cable; the two base stations receive the SRS and measure the TOA from the terminal device to themselves, and send the TOA to the positioning system, which calculates the location of the terminal device.

[0127] It should be pointed out that, Figure 2 and Figure 3 The example shown uses a mobile phone as the terminal device, but the embodiments of this application are not limited thereto.

[0128] Current positioning technologies rely on TOA measurements from at least two base stations to locate a terminal device, which limits their application scenarios. For example, the sides of a tunnel (e.g., a subway platform) may not allow for the deployment of additional base stations to avoid strong interference with other base stations. Furthermore, the portion of the leaky cable extending to the sides of the tunnel typically needs to be connected to a load to dissipate unnecessary signal energy. This results in the inability to achieve dual-station coverage on both sides of the tunnel, thus preventing the location of the terminal device.

[0129] Therefore, embodiments of this application provide a positioning method and a communication device, which can locate a terminal device even in the presence of a network device, and is applicable to various application scenarios, such as subways and tunnels. The method and device described in this application are based on the same technical concept. Since the principles by which the method and device solve problems are similar, the implementation of the device and method can be referred to each other, and repeated details will not be repeated.

[0130] In this application embodiment, "multiple" can refer to two or more. Therefore, in this application embodiment, "multiple" can also be understood as "at least two". "At least one" can be understood as one or more, such as one, two, or more. For example, "including at least one" means including one, two, or more. For example, including at least one of A, B, and C, then it could include A, B, C, A and B, A and C, B and C, or A, B, and C. "And / or" describes the association relationship between related objects. Specifically, there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0131] Unless otherwise specified, the ordinal numbers such as "first", "second", etc. mentioned in the embodiments of the present application are generally used to distinguish different objects, and are not used to limit the order, time sequence, priority or importance of the plurality of objects. For example, the first transmission line and the second transmission line in the embodiments of the present application are used to distinguish two transmission lines, and do not limit the priority or importance of the two transmission lines.

[0132] In addition, unless otherwise specified, the terms "system" and "network" in the embodiments of the present application can be used interchangeably, "according to" and "based on" can be replaced, "if" and "if" can be replaced, "when" and "in the case of" can be replaced.

[0133] In the embodiments of the present application, the device for realizing the function of the terminal device can be a terminal device, or a device capable of supporting the terminal device to realize the function, such as a circuit, a chip system or a combination device or component capable of realizing the function of the terminal device, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. The terminal device is described in detail in the embodiments of the present application. Figure 1 The related content of the illustrated embodiments is not repeated.

[0134] In the embodiments of the present application, the device for realizing the function of the network device can be a network device, or a device capable of supporting the network device to realize the function, such as a circuit, a chip system or a combination device or component capable of realizing the function of the network device, which can be installed in the network device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. The network device is described in detail in the embodiments of the present application. Figure 1 The related content of the illustrated embodiments is not repeated.

[0135] Please refer to Figure 4 , the architecture schematic diagram of the communication system 400 provided by the embodiments of the present application is shown. The communication system 400 can include one network device, one or more terminal devices and at least two transmission lines. Figure 4 In the embodiments of the present application, a network device, a terminal device and two transmission lines (such as the first transmission line and the second transmission line) are taken as an example. And, Figure 4 In the embodiments of the present application, the first transmission line and the second transmission line are represented by black thick lines. The network device includes one or more ports, one of which is referred to as the first port. Figure 4 In the embodiments of the present application, the network device includes two ports as an example. As Figure 4As shown, the first port of the network device is connected to one end of a first transmission line, the other end of the first transmission line is connected to one end of a second transmission line, and the first and second transmission lines are deployed in parallel. That is, the other end of the first transmission line is looped back to one end of the second transmission line. For example, the other end of the first transmission line and the other end of the second transmission line are looped back together via a jumper. This application embodiment does not limit the material of the jumper. Optionally, the other end of the second transmission line can be connected to a load (…). Figure 4 (Not shown in the diagram) to dissipate unwanted signal energy. Optionally, both the first and second transmission lines can be leaky cables, or both can be waveguides.

[0136] It should be noted that parallel deployment can be understood as relatively parallel deployment, or approximately parallel deployment, etc., without restriction. In other words, the first transmission line and the second transmission line can be deployed strictly in parallel, or they can be deployed approximately in parallel, without restriction.

[0137] In one possible implementation, the other end of the first transmission line can also be connected to one end of the second transmission line via a signal amplification device, such as... Figure 5 As shown. Figure 5 As shown, the communication system 400 may further include a signal amplification device connected to a first transmission line and a second transmission line via jumpers. This signal amplification device can amplify the signal passing through it. For example, the signal amplification device can receive a signal from the second transmission line, amplify it, and then send it to the first transmission line. As the signal travels through the transmission lines, its signal strength (or energy) gradually decreases. The lower the signal strength, the lower the accuracy of the TOA obtained by measuring the signal. When the signal transmission path is too long (e.g., the first and second transmission lines are deployed too long), the TOA may not be obtainable from the signal. In this implementation, the signal amplification device can amplify the signal, mitigating (or compensating for) the signal energy (or signal strength) loss during transmission from the second transmission line to the first port, thereby improving the accuracy of the TOA and increasing the deployable length of the first and second transmission lines.

[0138] It should be noted that the communication system 400 can further include more transmission lines. For example, the network device can be connected with multiple groups of transmission lines (e.g., X groups of transmission lines, X is an integer greater than 1), and each group of transmission lines includes two transmission lines, which can be deployed in the same manner as the first transmission line and the second transmission line. For example, the network device can further include a third port connected with one end of a third transmission line, and the other end of the third transmission line is connected with one end of a fourth transmission line, and the third transmission line and the fourth transmission line are deployed in parallel. The third transmission line and the fourth transmission line can be deployed in the same manner as the first transmission line and the second transmission line, which will not be repeated here. For brevity, the network device connected with one group of transmission lines will be taken as an example in the following description.

[0139] It should be understood that the communication system 400 can further include other devices, components, modules, or network elements not mentioned, or can only include part of the devices, components, or modules mentioned in the embodiments, without limitation. For example, the communication system 400 can further include a core network element and a LCS client (and / or AF), which will be described in detail with reference to the embodiment shown in Figure 1

[0140] Based on the communication system 400, the network device can receive the uplink signal of the terminal device through the first transmission line and the second transmission line, so as to realize the uplink positioning of the terminal device; or the network device can also send the downlink signal to the terminal device through the first transmission line and the second transmission line, so as to realize the downlink positioning of the terminal device.

[0141] The uplink positioning and the downlink positioning will be introduced in the following description of the communication system 400.

[0142] Figure 6 An exemplary flowchart of a first positioning method provided by the embodiments of the present application is shown. The first positioning method is applied to the communication system 400 shown in Figure 4 or Figure 5 The embodiments of the present application are described in the following description and attached drawings. It should be pointed out that the embodiments of the present application and the features in the embodiments of the present application can be combined with each other on the premise of not conflicting with each other. Figure 6 The method can include the following contents.

[0143] S601: The terminal device sends a third signal.

[0144] Correspondingly, the network device receives the first signal and the second signal.

[0145] ​In the embodiment, the third signal transmitted by the terminal device can reach a first reference position corresponding to the first transmission line of the terminal device through wireless transmission, and then be transmitted from the first reference position to the first port; and the third signal transmitted by the terminal device can reach a second reference position corresponding to the second transmission line of the terminal device through wireless transmission, and then be transmitted from the second reference position to the first port. That is, the third signal transmitted by the terminal device can reach the network device (or the first port of the network device) through two transmission paths (for example, a first transmission path and a second transmission path). The third signal can be a positioning reference signal, for example, an SRS, and the specific implementation form of the third signal is not limited in the embodiment.

[0146] The first transmission path can include a transmission path between the first reference position corresponding to the first transmission line of the terminal device and the first port. In a possible implementation, the first transmission path can further include a transmission path between the terminal device and the first reference position. In other words, the first transmission path can be a transmission path between the first reference position and the first port, as shown in FIG. 1; or the first transmission path can also be a transmission path between the terminal device, the first reference position and the first port. Figure 7

[0147] The second transmission path can include a transmission path between the second reference position corresponding to the second transmission line of the terminal device and the first port. In a possible implementation, the second transmission path can further include a transmission path between the terminal device and the second reference position. In other words, the second transmission path can be a transmission path between the second reference position and the first port, as shown in FIG. 1; or the second transmission path can also be a transmission path between the terminal device, the second reference position and the first port. Figure 7

[0148] The first reference position is located on the first transmission line. The first reference position can be understood as a point; or the first reference position can also be understood as a small area, for example, the small area can be an area of the first transmission line for receiving the third signal. For example, the first reference position can be a first intersection of a first straight line of the terminal device and the first transmission line; or the first reference position can also be a small area including the first intersection on the first transmission line. The first straight line is perpendicular to the first transmission line. The first straight line is also perpendicular to the second transmission line.

[0149] ​​The second reference position is located on the second transmission line. The second reference position can be understood as a point, or the second reference position can also be understood as a small area, for example, the small area can be an area of the second transmission line for receiving the third signal. Exemplarily, the second reference position can be a second intersection of the first straight line where the terminal device is located and the second transmission line, or the second reference position can also be a small area including the second intersection on the second transmission line.

[0150] For ease of understanding, the signal received by the network device through the first transmission path is referred to as the first signal in the embodiments of the present application, and correspondingly, the first signal can be the signal of the third signal reaching the first port through the first transmission path; and the signal received by the network device through the second transmission path is referred to as the second signal, and correspondingly, the second signal can be the signal of the third signal reaching the first port through the second transmission path.

[0151] It can be understood that S601 can also be expressed as S601a and S601b, Figure 6 S601a and S601b are exemplified. In S601a, the terminal device sends the third signal, and the network device receives the first signal through the first transmission path; in S601b, the terminal device sends the third signal, and the network device receives the second signal through the second transmission path.

[0152] S602: The network device determines the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path according to the first signal and the second signal.

[0153] The TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path can be used to determine the position information of the terminal device. For example, the network device can determine the TOA corresponding to the first transmission path according to the first signal, and determine the TOA corresponding to the second transmission path according to the second signal. The TOA corresponding to the first transmission path can be understood as the time difference from when the terminal device sends the third signal to when the third signal reaches the network device through the first transmission path. The TOA corresponding to the second transmission path can be understood as the time difference from when the terminal device sends the third signal to when the third signal reaches the network device through the second transmission path. The specific implementation process of the network device determining the TOA is not limited in the embodiments of the present application.

[0154] Figure 8 Exemplarily, a schematic diagram of the terminal device at different positions along the transmission line (for example, the first transmission line or the second transmission line) is shown. As Figure 8 If the terminal device is located at position 1, the terminal device is relatively close to the network device, and the power delay profile (PDP) of the first signal and the second signal can be as Figure 9As shown in (1); if the terminal device is located at position 2, and the distance between the terminal device and the network device is moderate, then the power delay spectrum of the first signal and the second signal can be as follows: Figure 9 As shown in (2); if the terminal device is located at position 3, which is far from the network device, then the power delay spectrum of the first signal and the second signal can be as follows: Figure 9 As shown in (3) above. Here, PDP refers to the relationship between the power of the signal received by the receiver and the time-of-arrival delay in a wireless channel. This PDP can be used to measure and obtain the TOA. For example... Figure 9 As shown, when the terminal device is in different locations, the interval between two TOAs (also known as multipath delay difference, or delay difference between the first and second transmission paths) differs, thus the location information of the terminal device can be determined using the interval between the two TOAs. Therefore, in this embodiment, even if only one network device exists, two TOAs with delay differences corresponding to the same signal can be obtained, thereby enabling the positioning of the terminal device.

[0155] In one possible implementation, the network device can determine the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path based on the first information, the first signal, and the second signal. The first information can also be referred to as fingerprint information (or fingerprint features) corresponding to the first and second transmission paths, etc., and the name of the first information is not limited in this embodiment. The first information may include the power value corresponding to the first transmission path and the power value corresponding to the second transmission path; or, the first information may include the power ratio between the first and second transmission paths; or, the first information may include the power value corresponding to the first and second transmission paths, and the power ratio between the first and second transmission paths. In one example, the network device can search a fingerprint information database based on the first information to obtain two reference TOAs corresponding to the first and second transmission paths, and determine the TOA corresponding to the first and second transmission paths based on these two reference TOAs, the first signal, and the second signal. That is, the network device determines the TOA corresponding to the first and second transmission paths based on these two reference TOAs, the TOA measured based on the first signal, and the TOA measured based on the second signal. In another example, the network device can also determine that the two reference TOAs are the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path, without having to measure the TOA corresponding to the first signal and the TOA corresponding to the second signal, which simplifies the calculation process.

[0156] The fingerprint information base, which can also be referred to as a fingerprint feature base, is not limited. Exemplarily, the network device can obtain, by a beacon manner, the fingerprint information of the multipath channel (e.g., including the first transmission path and the second transmission path) measured when the beacon device is at different positions along the transmission line (e.g., the first transmission line or the second transmission line), and construct the fingerprint information base. The fingerprint information base includes multiple groups of fingerprint information, each group of fingerprint information can include fingerprint information of the multipath channel (e.g., two transmission paths) corresponding to the position of the beacon device, and two reference TOAs associated with the fingerprint information. The two reference TOAs associated with the fingerprint information can be understood as two TOAs measured by measuring the signal transmitted by the multipath channel corresponding to the fingerprint information.

[0157] Taking the first transmission line and the second transmission line as an example, each position of the beacon device corresponds to two transmission paths. Assuming that the beacon device is at three positions (e.g., position 1, position 2, and position 3), the fingerprint information of the two transmission paths corresponding to the beacon device at position 1 can be denoted as fingerprint information 1, and the two reference TOAs associated with the fingerprint information 1 can be denoted as TOA1 and TOA2; the fingerprint information of the two transmission paths corresponding to the beacon device at position 2 can be denoted as fingerprint information 2, and the two reference TOAs associated with the fingerprint information 2 can be denoted as TOA3 and TOA4; the fingerprint information of the two transmission paths corresponding to the beacon device at position 3 can be denoted as fingerprint information 3, and the two reference TOAs associated with the fingerprint information 3 can be denoted as TOA5 and TOA6. Then, the fingerprint information base measured and constructed by the beacon device at position 1, position 2, and position 3 can include three groups of fingerprint information, which are {fingerprint information 1, TOA1 and TOA2}, {fingerprint information 2, TOA3 and TOA4}, and {fingerprint information 3, TOA5 and TOA6} respectively.

[0158] For example, as shown in FIG. 6, the network device can obtain, by a beacon manner, the fingerprint information of the multipath channel (e.g., including the first transmission path and the second transmission path) measured when the beacon device is at different positions along the transmission line (e.g., the first transmission line or the second transmission line), and construct the fingerprint information base. The fingerprint information base includes multiple groups of fingerprint information, each group of fingerprint information can include fingerprint information of the multipath channel (e.g., two transmission paths) corresponding to the position of the beacon device, and two reference TOAs associated with the fingerprint information. The two reference TOAs associated with the fingerprint information can be understood as two TOAs measured by measuring the signal transmitted by the multipath channel corresponding to the fingerprint information. Figure 9As shown in (1), when the terminal device is located close to the network device, the TOA corresponding to the first transmission path is smaller, the power of the first signal received by the network device through the first transmission path is larger, the TOA corresponding to the second transmission path is larger, and the power of the second signal received by the network device through the second transmission path is smaller. This means that the power ratio between the first signal and the second signal is larger (or the power ratio corresponding to the first transmission path and the second transmission path is larger, or the difference between the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path is larger). Thus, when the terminal device is located very close to the network device and the transmission line deployment range is large, the second transmission path is longer. As the signal is transmitted, the signal strength of the signal gradually decreases, and there may be a situation where the TOA corresponding to the second transmission path cannot be accurately obtained, resulting in the inability to locate the terminal device. In the above embodiment, the network device can use the first information to help determine the two TOAs used for positioning, thereby avoiding the problem that the two TOAs cannot be obtained when the terminal device is close to the network device, which leads to the inability to locate the terminal device.

[0159] For example, such as Figure 9 As shown in (3), when the terminal device is located near the end of the section where the transmission line is deployed (e.g., near the end of the first transmission line that is not connected to the first port), the TOA corresponding to the first transmission path is close to the TOA corresponding to the second transmission path. The power of the first signal received by the network device through the first transmission path is also close to the power of the second signal received through the second transmission path. This means that the power ratio between the first signal and the second signal is approximately 1 (or the power ratio between the first transmission path and the second transmission path is approximately 1, or the difference between the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path is small). Thus, when the terminal device is located very close to the end of the section where the transmission line is deployed, the network device may only be able to measure a single TOA, resulting in the inability to locate the terminal device. In the above embodiment, the network device can use the first information to help determine the two TOAs used for positioning, thereby avoiding the problem that the terminal device cannot be located because it is too close to the end of the section where the transmission line is deployed and therefore cannot obtain the two TOAs.

[0160] In one possible implementation, if Figure 4 or Figure 5The communication system 400 shown includes X groups of transmission lines, then in S601, the network device can receive X first signals and X second signals, and in S602, the network device can determine the TOA corresponding to the X first transmission paths and the TOA corresponding to the X second transmission paths according to the X first signals and the X second signals. Wherein, X is an integer greater than 1. The deployment mode of the X groups of transmission lines is described above, and will not be repeated here. Further, the network device can perform mean operation on the TOA corresponding to the X first transmission paths to obtain the TOA corresponding to the first transmission path, and perform mean operation on the TOA corresponding to the X second transmission paths to obtain the TOA corresponding to the second transmission path, which is not limited. Through the implementation mode, the network device can obtain 2X TOAs, which can improve the positioning accuracy.

[0161] Optionally, the first positioning method can further include S603 and S604; or the first positioning method can further include S605, Figure 6 The position information of the terminal device can be determined by the core network device, or the position information of the terminal device can also be determined by the network device.

[0162] S603: The network device sends the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path to the core network device.

[0163] Correspondingly, the core network device receives the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path from the network device.

[0164] The core network device may, for example, be an LMF network element, but is not limited thereto. It should be understood that if Figure 4 Or Figure 5 The communication system 400 shown includes X groups of transmission lines, and the network device obtains 2X TOAs, then the network device can perform mean operation on the 2X TOAs to obtain two TOAs, and then send the two TOAs to the core network device; or the network device can also directly send the 2X TOAs to the core network device, which is not limited.

[0165] S604: The core network device determines the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path.

[0166] Exemplarily, the core network device can determine the position information of the terminal device according to the TOA corresponding to the first transmission path, the TOA corresponding to the second transmission path, the total length of the first transmission line and the second transmission line, and a first parameter. The first parameter includes the transmission speed of the third signal in the first transmission line, or the first parameter includes the transmission speed of the third signal in the second transmission line, or the first parameter includes the transmission speed of the third signal in the first transmission line and the transmission speed of the third signal in the second transmission line. The embodiments of the present application do not limit the specific implementation process of the core network device for determining the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path.

[0167] S605: The network device determines the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path.

[0168] Exemplarily, the network device can determine the position information of the terminal device according to the TOA corresponding to the first transmission path, the TOA corresponding to the second transmission path, the total length of the first transmission line and the second transmission line, and a first parameter. The first parameter includes the transmission speed of the third signal in the first transmission line, or the first parameter includes the transmission speed of the third signal in the second transmission line, or the first parameter includes the transmission speed of the third signal in the first transmission line and the transmission speed of the third signal in the second transmission line. The embodiments of the present application do not limit the specific implementation process of the network device for determining the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the second transmission path.

[0169] Through the above first positioning method, even if there is only one network device, at least two TOAs can be obtained, so that the positioning of the terminal device can be realized, and the method can be applied to various application scenarios.

[0170] The above describes the uplink positioning based on the communication system 400. Next, the downlink positioning based on the communication system 400 is described.

[0171] Figure 10 Exemplarily, a flowchart of the second positioning method provided by the embodiments of the present application is shown. The second positioning method is applied to the communication system 400 as shown in Figure 4 or Figure 5 The embodiments of the present application are for the scenario of downlink positioning. As shown in Figure 10 The method can include the following contents.

[0172] S1001: The network device sends the eighth signal.

[0173] Correspondingly, the terminal device receives the ninth signal and the tenth signal.

[0174] In this embodiment, the eighth signal transmitted by the network device can be transmitted from the first port to the first reference position and then transmitted to the terminal device through wireless transmission; and the eighth signal transmitted by the network device can be transmitted from the first port to the second reference position and then transmitted to the terminal device through wireless transmission. That is, the eighth signal transmitted by the network device can reach the terminal device through two transmission paths (for example, the seventh transmission path and the eighth transmission path). The eighth signal can be a positioning reference signal or a pilot signal, and the specific implementation form of the eighth signal is not limited in the embodiment of the application. The first reference position and the second reference position are described above and will not be described here.

[0175] The seventh transmission path can include a transmission path between the first port and the first reference position. In a possible implementation, the seventh transmission path can further include a transmission path between the first reference position and the terminal device. In other words, the seventh transmission path can be a transmission path between the first port and the first reference position, as shown in FIG. 7A; or the seventh transmission path can also be a transmission path between the first port and the first reference position and a transmission path between the first reference position and the terminal device. Figure 11

[0176] The eighth transmission path can include a transmission path between the first port and the second reference position. In a possible implementation, the eighth transmission path can further include a transmission path between the second reference position and the terminal device. In other words, the eighth transmission path can be a transmission path between the first port and the second reference position, as shown in FIG. 8A; or the eighth transmission path can also be a transmission path between the first port and the second reference position and a transmission path between the second reference position and the terminal device. Figure 11

[0177] For ease of understanding, the signal received by the terminal device through the seventh transmission path is referred to as the ninth signal in the embodiment of the application, and correspondingly, the ninth signal can be the signal of the eighth signal reaching the terminal device through the seventh transmission path; and the signal received by the terminal device through the eighth transmission path is referred to as the tenth signal, and correspondingly, the tenth signal can be the signal of the eighth signal reaching the terminal device through the eighth transmission path.

[0178] It can be understood that S1001 can also be expressed as S1001a and S1001b, Figure 10 for example, S1001a and S1001b are illustrated in S1001a and S1001b. In S1001a, the network device transmits the eighth signal, and the terminal device receives the ninth signal through the seventh transmission path; in S1001b, the network device transmits the eighth signal, and the terminal device receives the tenth signal through the eighth transmission path.

[0179] ​​S1002: The terminal device determines the TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path according to the ninth signal and the tenth signal.

[0180] The TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path can be used to determine the position information of the terminal device. For example, the terminal device can determine the TOA corresponding to the seventh transmission path according to the ninth signal, and determine the TOA corresponding to the eighth transmission path according to the tenth signal. The TOA corresponding to the seventh transmission path can be understood as the time difference between the time when the network device sends the eighth signal and the time when the eighth signal reaches the terminal device through the seventh transmission path. The TOA corresponding to the eighth transmission path can be understood as the time difference between the time when the network device sends the eighth signal and the time when the eighth signal reaches the terminal device through the eighth transmission path. The specific implementation process of the terminal device determining the TOA is not limited in the embodiments of the present application.

[0181] In a possible implementation, the terminal device can determine the TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path according to the third information, the ninth signal and the tenth signal. The third information can also be referred to as a fingerprint information base of the seventh transmission path and the eighth transmission path, or a fingerprint information base, etc. The name of the third information is not limited in the embodiments of the present application. The third information can include the power value corresponding to the seventh transmission path and the power value corresponding to the eighth transmission path; or the third information can include the power ratio between the seventh transmission path and the eighth transmission path; or the third information can include the power value corresponding to the seventh transmission path and the power value corresponding to the eighth transmission path, and the power ratio between the seventh transmission path and the eighth transmission path. For the description of the third information, please refer to the description of the first information above, which will not be repeated. In the above implementation, the terminal device uses the third information to assist in determining two TOAs for positioning, so as to avoid the problem that the terminal device cannot obtain two TOAs when the terminal device is close to the network device, and cannot realize the positioning of the terminal device, and avoid the problem that the terminal device cannot obtain two TOAs when the terminal device is close to the end of the interval segment where the transmission line is deployed, and cannot realize the positioning of the terminal device.

[0182] In a possible implementation, if Figure 4 or Figure 5The communication system 400 shown includes X groups of transmission lines, and then in S1001, the terminal device can receive X ninth signals and X tenth signals, and in S1002, the terminal device can determine the TOA corresponding to the X seventh transmission paths and the TOA corresponding to the X eighth transmission paths according to the X ninth signals and the X tenth signals. Wherein, X is an integer greater than 1. The deployment mode of the X groups of transmission lines is described above, and will not be repeated here. Further, the terminal device can perform mean operation on the TOA corresponding to the X seventh transmission paths to obtain the TOA corresponding to the seventh transmission path, and perform mean operation on the TOA corresponding to the X eighth transmission paths to obtain the TOA corresponding to the eighth transmission path, without limitation. In this implementation mode, the terminal device can obtain 2X TOAs, which can improve the positioning accuracy.

[0183] Optionally, the second positioning method can further include S1003 and S1004, Figure 10 The position information of the terminal device can be determined by the core network device, but is not limited thereto.

[0184] S1003: The terminal device sends the TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path to the core network device.

[0185] Correspondingly, the core network device receives the TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path from the terminal device.

[0186] The core network device may, for example, be an LMF network element, but is not limited thereto. For example, the terminal device can send the TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path to the core network device through an LTE positioning protocol (LPP) message or an RRC message. It should be understood that if Figure 4 or Figure 5 The communication system 400 shown includes X groups of transmission lines, and the terminal device obtains 2X TOAs, so the terminal device can perform mean operation on the 2X TOAs to obtain two TOAs, and then send the two TOAs to the core network device; or the terminal device can also directly send the 2X TOAs to the core network device, without limitation.

[0187] S1004: The core network device determines the position information of the terminal device according to the TOA corresponding to the seventh transmission path and the TOA corresponding to the eighth transmission path.

[0188] For example, the core network device can determine the location information of the terminal device based on the TOA corresponding to the seventh transmission path, the TOA corresponding to the eighth transmission path, the total length of the first and second transmission lines, and a second parameter. The second parameter includes the transmission speed of the eighth signal in the first transmission line, or the second parameter includes the transmission speed of the eighth signal in the second transmission line, or the second parameter includes both the transmission speeds of the eighth signal in the first and second transmission lines. This application embodiment does not limit the specific implementation process of the core network device determining the location information of the terminal device based on the TOA corresponding to the seventh and eighth transmission paths.

[0189] In the second positioning method described above, even if there is only one network device, two TOAs can be obtained, thereby enabling the positioning of the terminal device and making it applicable to a variety of application scenarios.

[0190] exist Figure 4 or Figure 5 In the communication system 400 shown, the other end of the second transmission line (i.e., the end not connected to the first transmission line) can be connected to a load. In another possible implementation, the network device may further include a second port, and the other end of the second transmission line can also be connected to a second port of the network device, such as... Figure 12 As shown.

[0191] Please see Figure 12 This is a schematic diagram of the architecture of a communication system 1200 provided in an embodiment of this application. The communication system 1200 may include a network device, one or more terminal devices, and at least two transmission lines. Figure 12 The example illustrates a network device, a terminal device, and two transmission lines (referred to as the first transmission line and the second transmission line). Furthermore, Figure 12 The first transmission line and the second transmission line are represented by thick black lines. The network device includes multiple ports, two of which are designated as the first port and the second port, respectively. Figure 12 The example shown is a network device with two ports. Figure 12 As shown, the first port of the network device is connected to one end of the first transmission line, the other end of the first transmission line is connected to one end of the second transmission line, the other end of the second transmission line is connected to the second port of the network device, and the first and second transmission lines are deployed in parallel. That is, the other end of the first transmission line and the first end of the second transmission line are looped back together. For example, the other end of the first transmission line and the first end of the second transmission line are looped back together via a patch cord. This application embodiment does not limit the material of the patch cord. Optionally, both the first and second transmission lines can be leaky cables, or both can be waveguides. For parallel deployment, please refer to the foregoing content, which will not be repeated here.

[0192] In a possible implementation, the other end of the first transmission line can also be connected to one end of the second transmission line through a signal amplification device, as shown in Figure 13 Figure 13 As shown in , the communication system 1200 can also include a signal amplification device connected to the first transmission line through a jumper and connected to the second transmission line through a jumper. The signal amplification device can be used to amplify the signal passing through the signal amplification device. For example, the signal amplification device can receive a signal from the second transmission line, amplify the signal and send it to the first transmission line. For another example, the signal amplification device can also receive a signal from the first transmission line, amplify the signal and send it to the second transmission line. As the signal strength of the signal decreases gradually during transmission in the transmission line, the accuracy of the TOA obtained by measuring the signal is also lower. When the transmission path of the signal is too long (for example, the first transmission line and the second transmission line are deployed too long), the TOA cannot be obtained according to the signal. In this implementation, the signal amplification device can amplify the passing signal, which can alleviate the signal energy (or signal strength) lost during the transmission of the signal from the second transmission line to the first port or from the first transmission line to the second port, thereby improving the accuracy of the TOA and increasing the length of the first transmission line and the second transmission line that can be deployed.

[0193] It should be noted that the communication system 1200 can also include more transmission lines. For example, the network device can be connected to multiple groups of transmission lines (for example, N groups of transmission lines, N is an integer greater than 1), each group of transmission lines includes two transmission lines, and the deployment of the two transmission lines can refer to the deployment of the first transmission line and the second transmission line. For example, the network device can also include a third port and a fourth port, one end of the third transmission line is connected to the third port, the other end of the third transmission line is connected to one end of the fourth transmission line, the other end of the fourth transmission line is connected to the fourth port, and the third transmission line and the fourth transmission line are deployed in parallel. The third transmission line and the fourth transmission line can refer to the description of the first transmission line and the second transmission line, and will not be described again. For the sake of brevity, the network device connected to a group of transmission lines is described hereinafter.

[0194] It should be understood that the communication system 1200 can also include other devices, components, modules, or network elements not mentioned, or can only include part of the devices, components, or modules mentioned in the embodiments, without limitation. For example, the communication system 1200 can also include core network elements and LCS clients (and / or AFs), which will be described in detail with reference to the embodiment shown in Figure 1

[0195] In a possible implementation, based on​Figure 12 or Figure 13 As shown in the communication system 1200, the first positioning method can further include that the network device can further receive the fourth signal and the fifth signal. For example, the S601 can be replaced by: the terminal device sends the third signal; and correspondingly, the network device receives the first signal, the second signal, the fourth signal and the fifth signal. In this implementation manner, the other end of the second transmission line is connected with the second port of the network device. Then, the third signal sent by the terminal device can reach the network device through another two transmission paths (for example, the third transmission path and the fourth transmission path) in addition to the first transmission path and the second transmission path. Specifically, the third signal sent by the terminal device can be transmitted wirelessly to the first reference position and then transmitted from the first reference position to the first port; the third signal sent by the terminal device can be transmitted wirelessly to the second reference position and then transmitted from the second reference position to the first port; the third signal sent by the terminal device can be transmitted wirelessly to the first reference position and then transmitted from the first reference position to the second port; and the third signal sent by the terminal device can be transmitted wirelessly to the second reference position and then transmitted from the second reference position to the second port. The first reference position and the second reference position are as described above, and will not be described here.

[0196] The third transmission path can include a transmission path between the second reference position and the second port. In a possible implementation manner, the third transmission path can further include a transmission path between the terminal device and the second reference position. In other words, the third transmission path can be a transmission path between the second reference position and the second port, as shown in FIG. 12; or the third transmission path can be a transmission path between the terminal device, the second reference position and the second port. Figure 14 The fourth transmission path can include a transmission path between the first reference position and the second port. In a possible implementation manner, the fourth transmission path can further include a transmission path between the terminal device and the first reference position. In other words, the fourth transmission path can be a transmission path between the first reference position and the second port, as shown in FIG. 12; or the fourth transmission path can be a transmission path between the terminal device, the first reference position and the second port.

[0197] Figure 14

[0198] ​​For the convenience of understanding, the signal received by the network device through the third transmission path is referred to as a fourth signal in the embodiments of the present application, and correspondingly, the fourth signal can be the signal of the third signal reaching the second port through the third transmission path; and the signal received by the network device through the fourth transmission path is referred to as a fifth signal, and correspondingly, the fifth signal can be the signal of the third signal reaching the second port through the fourth transmission path.

[0199] Further, the network device determines the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path according to the fourth signal and the fifth signal, and the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path are used to determine the position information of the terminal device. For example, S602 can be replaced by: the network device determines the TOA corresponding to the first transmission path, the TOA corresponding to the second transmission path, the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path according to the first signal, the second signal, the fourth signal and the fifth signal. For example, the network device determines the TOA corresponding to the first transmission path according to the first signal, determines the TOA corresponding to the second transmission path according to the second signal, determines the TOA corresponding to the third transmission path according to the fourth signal, and determines the TOA corresponding to the fourth transmission path according to the fifth signal.

[0200] In an example, the network device can determine the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path according to the fourth information, the fourth signal and the fifth signal. The fourth information can also be referred to as a fingerprint information library of the third transmission path and the fourth transmission path, or a fingerprint information library, etc., and the name of the fourth information in the embodiments of the present application is not limited. The fourth information can include the power value corresponding to the third transmission path and the power value corresponding to the fourth transmission path; or the fourth information can include the power ratio between the third transmission path and the fourth transmission path; or the fourth information can include the power value corresponding to the third transmission path and the power value corresponding to the fourth transmission path, and the power ratio between the third transmission path and the fourth transmission path. For the description of the fourth information, please refer to the description of the first information described above, which will not be repeated. Optionally, the fourth information can be the same as the first information, or can be different. In the above example, the network device uses the fourth information to assist in determining two TOAs for positioning, so as to avoid the problem that the positioning of the terminal device cannot be realized due to the inability to obtain two TOAs when the terminal device is close to the network device, and avoid the problem that the positioning of the terminal device cannot be realized due to the inability to obtain two TOAs when the terminal device is close to the end of the interval segment where the transmission line is deployed.

[0201] In an example, if Figure 12 or Figure 13The communication system 1200 shown includes N groups of transmission lines, so the network device can receive N first signals, N second signals, N fourth signals and N fifth signals. And the network device can determine the TOA corresponding to the N first transmission paths, the TOA corresponding to the N second transmission paths, the TOA corresponding to the N third transmission paths and the TOA corresponding to the N fourth transmission paths according to the N first signals, the N second signals, the N fourth signals and the N fifth signals. Wherein, N is an integer greater than 1. The deployment mode of the N groups of transmission lines is described above, and will not be described here. Further, the network device can perform mean operation on the TOA corresponding to each transmission path, which is described above, and will not be described here. Through the present example, the network device can obtain 4N TOAs, which can improve the positioning accuracy.

[0202] In the present implementation, the network device can send the TOA corresponding to the first transmission path, the TOA corresponding to the second transmission path, the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path to the core network device; correspondingly, the core network device determines the position information of the terminal device according to the TOA corresponding to the first transmission path, the TOA corresponding to the second transmission path, the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path. Alternatively, the network device can also perform mean operation on the TOA corresponding to the first transmission path and the TOA corresponding to the third transmission path, and perform mean operation on the TOA corresponding to the second transmission path and the TOA corresponding to the fourth transmission path, to obtain two TOAs, and send the two TOAs to the core network device; correspondingly, the core network device determines the position information of the terminal device according to the two TOAs. Alternatively, the network device determines the position information of the terminal device according to the TOA corresponding to the first transmission path, the TOA corresponding to the second transmission path, the TOA corresponding to the third transmission path and the TOA corresponding to the fourth transmission path. The specific implementation process is described in the content of S603, S604 and S605, and will not be described here.

[0203] In the above implementation, even if there is only one network device, at least four TOAs can be obtained, so that the positioning of the terminal device can be realized, the positioning accuracy can be improved, and the method can be applied to various application scenarios.

[0204] In another possible implementation, based on Figure 12 or Figure 13The communication system 1200 shown above, in its second positioning method, may further include: the network device may transmit an eleventh signal; correspondingly, the terminal device may receive a twelfth and thirteenth signal. Exemplarily, S1001 can be replaced by: the network device transmitting an eighth and eleventh signal; correspondingly, the terminal device receiving a ninth, tenth, twelfth, and thirteenth signal. The eleventh signal may be a positioning reference signal or a pilot signal; the specific implementation of the eleventh signal is not limited in this embodiment. Optionally, the eleventh signal and the eighth signal may be the same or different.

[0205] In this implementation, the other end of the second transmission line is connected to the second port of the terminal device. Therefore, the eighth signal sent by the network device through the first port can reach the terminal device via the seventh and eighth transmission paths, and the eleventh signal sent by the network device through the second port can reach the terminal device via two other transmission paths (such as the ninth and tenth transmission paths). Specifically, the eighth signal sent by the network device can be transmitted from the first port to the first reference position and then wirelessly transmitted to the terminal device; the eighth signal sent by the network device can be transmitted from the first port to the second reference position and then wirelessly transmitted to the terminal device; the eleventh signal sent by the network device can be transmitted from the second port to the second reference position and then wirelessly transmitted to the terminal device; and the eleventh signal sent by the network device can be transmitted from the second port to the first reference position and then wirelessly transmitted to the terminal device. The first reference position, second reference position, seventh transmission path, and eighth transmission path are described above and will not be repeated here.

[0206] The ninth transmission path may include a transmission path from the second port to the second reference position. In one possible implementation, the ninth transmission path may further include a transmission path from the second reference position to the terminal device. In other words, the ninth transmission path may be a transmission path from the second port to the second reference position, such as... Figure 15 As shown; or the ninth transmission path may also be a transmission path from the second port to the second reference position and then from the second reference position to the terminal device.

[0207] The tenth transmission path may include a transmission path from the second port to the first reference position. In one possible implementation, the tenth transmission path may further include a transmission path from the first reference position to the terminal device. In other words, the tenth transmission path can be a transmission path from the second port to the first reference position, such as... Figure 15 As shown; or the tenth transmission path can also be a transmission path from the second port to the first reference position and then from the first reference position to the terminal device.

[0208] For the convenience of understanding, the signal received by the terminal device through the ninth transmission path is referred to as a twelfth signal in the embodiments of the present application, and correspondingly, the twelfth signal can be the signal of the eleventh signal reaching the second port through the ninth transmission path; and the signal received by the terminal device through the tenth transmission path is referred to as a thirteenth signal, and correspondingly, the thirteenth signal can be the signal of the eleventh signal reaching the second port through the tenth transmission path.

[0209] Further, the terminal device can determine the TOA corresponding to the ninth transmission path and the TOA corresponding to the tenth transmission path according to the twelfth signal and the thirteenth signal, and the TOA corresponding to the ninth transmission path and the TOA corresponding to the tenth transmission path are used to determine the position information of the terminal device. For example, S1002 can be replaced by: the terminal device determines the TOA corresponding to the seventh transmission path, the TOA corresponding to the eighth transmission path, the TOA corresponding to the ninth transmission path and the TOA corresponding to the tenth transmission path according to the ninth signal, the tenth signal, the twelfth signal and the thirteenth signal. For example, the terminal device determines the TOA corresponding to the seventh transmission path according to the ninth signal, determines the TOA corresponding to the eighth transmission path according to the tenth signal, determines the TOA corresponding to the ninth transmission path according to the twelfth signal, and determines the TOA corresponding to the tenth transmission path according to the thirteenth signal.

[0210] In an example, the terminal device can determine the TOA corresponding to the ninth transmission path and the TOA corresponding to the tenth transmission path according to the fifth information, the twelfth signal and the thirteenth signal. The fifth information can also be referred to as a fingerprint information base of the ninth transmission path and the tenth transmission path, or a fingerprint information base, etc., and the name of the fifth information in the embodiments of the present application is not limited. The fifth information can include the power value corresponding to the ninth transmission path and the power value corresponding to the tenth transmission path; or the fifth information can include the power ratio between the ninth transmission path and the tenth transmission path; or the fifth information can include the power value corresponding to the ninth transmission path and the power value corresponding to the tenth transmission path, and the power ratio between the ninth transmission path and the tenth transmission path. For the description of the fifth information, please refer to the foregoing description of the first information, which will not be repeated. Alternatively, the fifth information can be the same as the third information, or can be different. In the above example, the terminal device can use the fifth information to assist in determining two TOAs for positioning, so as to avoid the problem that the positioning of the terminal device cannot be implemented due to the inability to obtain two TOAs when the network device is close to the terminal device, and avoid the problem that the positioning of the terminal device cannot be implemented due to the inability to obtain two TOAs when the network device is close to the end of the interval segment of the transmission line.

[0211] In an example, if Figure 12 or Figure 13The communication system 1200 shown includes N groups of transmission lines, so that the terminal device can receive N ninth signals, N tenth signals, N twelfth signals and N thirteenth signals. And the terminal device can determine the TOA corresponding to the N seventh transmission paths, the TOA corresponding to the N eighth transmission paths, the TOA corresponding to the N ninth transmission paths and the TOA corresponding to the N tenth transmission paths according to the N ninth signals, the N tenth signals, the N twelfth signals and the N thirteenth signals. Wherein, N is an integer greater than 1. The deployment mode of the N groups of transmission lines is described above, and will not be described here. Further, the terminal device can perform mean operation on the TOA corresponding to each transmission path, which is described above, and will not be described here. Through the present example, the terminal device can obtain 4N TOAs, which can improve the positioning accuracy.

[0212] In the present implementation, the terminal device can send the TOA corresponding to the seventh transmission path, the TOA corresponding to the eighth transmission path, the TOA corresponding to the ninth transmission path and the TOA corresponding to the tenth transmission path to the core network device; correspondingly, the core network device determines the position information of the terminal device according to the TOA corresponding to the seventh transmission path, the TOA corresponding to the eighth transmission path, the TOA corresponding to the ninth transmission path and the TOA corresponding to the tenth transmission path. Alternatively, the terminal device can also perform mean operation on the TOA corresponding to the seventh transmission path and the TOA corresponding to the ninth transmission path, and perform mean operation on the TOA corresponding to the eighth transmission path and the TOA corresponding to the tenth transmission path, obtain two TOAs, and send the two TOAs to the core network device; correspondingly, the core network device determines the position information of the terminal device according to the two TOAs. The specific implementation process is described in S1003 and S1004, and will not be described here.

[0213] In the above implementation, even if there is only one network device, at least four TOAs can be obtained, so that the positioning of the terminal device can be realized, the positioning accuracy can be improved, and it can be applied to various application scenarios.

[0214] The foregoing communication system 400 or communication system 1200 needs to include at least two transmission lines. In another possible implementation, the communication system can also include at least one transmission line, such as Figure 16 as shown.

[0215] Please refer to Figure 16 , the architecture schematic diagram of the communication system 1600 provided by the embodiments of the present application. The communication system 1600 can include one network device, one or more terminal devices and at least one transmission line. Figure 16 The network device, the terminal device and the transmission line (such as the first transmission line) are taken as an example in the above implementation. Figure 16The first transmission line is represented by a thick black line. The network device includes one or more ports, one of which is designated as the first port. Figure 16 The example shown is a network device with two ports. Figure 16 As shown, the first port of the network device is connected to one end of a first transmission line, and the first transmission line is bent and deployed in parallel as a dual transmission line. Optionally, the other end of the first transmission line can be connected to a load. Figure 16 (Not shown in the image) to dissipate useless signal energy. Optionally, the first transmission line can be a leaky cable, or the first transmission line can be a waveguide. For parallel deployment, please refer to the foregoing content, which will not be repeated here. The parallel deployment of the first transmission line in the form of two transmission lines after being bent can also be described as: the first transmission line is bent and then deployed in parallel, etc.

[0216] It should be noted that the communication system 1600 may also include more transmission lines. For example, the network device may be connected to multiple sets of transmission lines (e.g., denoted as Y sets of transmission lines, where Y is an integer greater than 1), each set including one transmission line, the deployment of which can refer to the deployment of the first transmission line. For instance, the network device may also include a third port connected to one end of a third transmission line, and the third transmission line may be bent and deployed in parallel as two transmission lines. The description of these three transmission lines can refer to the description of the first transmission line, and will not be repeated here. For simplicity, the following explanation uses the connection of the network device to a set of transmission lines as an example.

[0217] It should be understood that the communication system 1600 may also include other unmentioned devices, components, modules, or network elements, or may only include some of the devices, components, or modules mentioned in the embodiments, without limitation. For example, the communication system 1600 may also include core network elements and LCS clients (and / or AFs), please refer to [reference needed] for details. Figure 1 The description of the illustrated embodiments will not be repeated.

[0218] Based on the communication system 1600, the network device can receive uplink signals from the terminal device through the first transmission line to achieve uplink positioning of the terminal device; or, the network device can also send downlink signals to the terminal device through the first transmission line to achieve downlink positioning of the terminal device.

[0219] The following section will introduce uplink positioning and downlink positioning in conjunction with the 1600 communication system.

[0220] Figure 17 A schematic flowchart of the third positioning method provided in this application embodiment is shown as an example. This third positioning method is applied to... Figure 16 The communication system 1600 shown is illustrated. This embodiment describes an uplink positioning scenario. For example...Figure 17 As shown, the method can include the following.

[0221] S1701: The terminal device transmits a third signal.

[0222] Correspondingly, the network device receives the first signal and the sixth signal.

[0223] In this embodiment, the third signal transmitted by the terminal device can reach a first reference position corresponding to the first transmission line of the terminal device through wireless transmission, and then be transmitted from the first reference position to the first port; and the third signal transmitted by the terminal device can reach a third reference position corresponding to the first transmission line of the terminal device through wireless transmission, and then be transmitted from the third reference position to the first port. That is, the third signal transmitted by the terminal device can reach the network device (or the first port of the network device) through two transmission paths (such as the first transmission path and the fifth transmission path). The third signal, the first transmission path and the first reference position are as previously described, and will not be described here again.

[0224] The fifth transmission path can include a transmission path between the third reference position and the first port. In a possible implementation, the fifth transmission path can also include a transmission path between the terminal device and the third reference position. In other words, the fifth transmission path can be a transmission path between the third reference position and the first port, which can be similar to the second transmission path in the embodiment shown in Figure 7 ; or the fifth transmission path can also be a transmission path between the terminal device, the third reference position and the first port.

[0225] The third reference position is located on the first transmission line. The third reference position can be understood as a point; or the third reference position can also be understood as a small area, for example, the small area can be an area of the first transmission line for receiving the third signal. Exemplarily, the third reference position can be a third intersection of the first straight line where the terminal device is located and the first transmission line; or the third reference position can also be a small area of the first transmission line including the third intersection. The third intersection is different from the first intersection. In this embodiment, the first transmission line is deployed in parallel in the form of double transmission lines after being bent, so that the first straight line where the terminal device is located has two intersections with the first transmission line, i.e., the first intersection and the third intersection, and the two intersections are respectively located on the two sides of the parallel part of the first transmission line. Correspondingly, the third reference position and the first reference position can be respectively located on the two sides of the parallel part of the first transmission line. The third reference position can be similar to the second reference position in the embodiment shown in Figure 7

[0226] ​For the convenience of understanding, the signal received by the network device through the first transmission path in the embodiments of the present application is referred to as the first signal, and correspondingly, the first signal can be the signal of the third signal reaching the first port through the first transmission path; and the signal received by the network device through the fifth transmission path is referred to as the sixth signal, and correspondingly, the sixth signal can be the signal of the third signal reaching the first port through the fifth transmission path.

[0227] It can be understood that S1701 can also be expressed as S1701a and S1701b, Figure 17 S1701a and S1701b are exemplified in the embodiments. In S1701a, the terminal device transmits the third signal, and the network device receives the first signal through the first transmission path; in S1701b, the terminal device transmits the third signal, and the network device receives the sixth signal through the fifth transmission path.

[0228] S1702: The network device determines the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path according to the first signal and the sixth signal.

[0229] The TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path can be used to determine the position information of the terminal device. For example, the network device can determine the TOA corresponding to the first transmission path according to the first signal, and determine the TOA corresponding to the fifth transmission path according to the sixth signal. The TOA corresponding to the first transmission path can be understood as the time difference from when the terminal device transmits the third signal to when the third signal reaches the network device through the first transmission path. The TOA corresponding to the fifth transmission path can be understood as the time difference from when the terminal device transmits the third signal to when the third signal reaches the network device through the fifth transmission path. The specific implementation process of the network device determining the TOA is not limited in the embodiments of the present application.

[0230] In a possible implementation, the network device can determine the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path according to the second information, the first signal, and the sixth signal. The second information can also be referred to as a fingerprint information base of the first transmission path and the fifth transmission path, or a fingerprint information base, and the name of the second information in this embodiment of the application is not limited. The second information can include a power value corresponding to the first transmission path and a power value corresponding to the fifth transmission path, or the second information can include a power ratio between the first transmission path and the fifth transmission path, or the second information can include the power value corresponding to the first transmission path, the power value corresponding to the fifth transmission path, and the power ratio between the first transmission path and the fifth transmission path. For details of the second information, refer to the description of the first information, and details are not repeated. In the foregoing implementation, the network device can use the second information to assist in determining two TOAs for positioning, thereby avoiding the problem that the terminal device cannot obtain two TOAs when the terminal device is close to the network device, and the problem that the terminal device cannot obtain two TOAs when the terminal device is close to the end of the interval of the transmission line, and thus the positioning of the terminal device cannot be implemented.

[0231] In a possible implementation, if Figure 16 As shown in the communication system 1600, the communication system 1600 includes Y groups of transmission lines. In S1701, the network device can receive Y first signals and Y sixth signals, and in S1702, the network device can determine the TOA corresponding to the Y first transmission paths and the TOA corresponding to the Y fifth transmission paths according to the Y first signals and the Y sixth signals. Y is an integer greater than 1. For details of the deployment of the Y groups of transmission lines, refer to the foregoing content, and details are not repeated. Further, the network device can perform mean operation on the TOA corresponding to the Y first transmission paths to obtain the TOA corresponding to the first transmission path, and perform mean operation on the TOA corresponding to the Y fifth transmission paths to obtain the TOA corresponding to the fifth transmission path, which is not limited. Through this implementation, the network device can obtain 2Y TOAs, and the positioning accuracy can be improved.

[0232] Optionally, the third positioning method can further include S1703 and S1704, or the third positioning method can further include S1705, Figure 17 In S1703, the network device can send the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path to the core network device. In S1704, the core network device can determine the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path. In S1705, the network device can determine the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path. In the foregoing implementations, the position information of the terminal device can be determined by the core network device, or the position information of the terminal device can also be determined by the network device.

[0233] S1703: The network device sends the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path to the core network device.

[0234] Correspondingly, the core network device receives the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path from the network device.

[0235] The core network device may, for example, be an LMF network element, but is not limited thereto. It should be understood that if Figure 16 The communication system 1600 shown in the figure includes Y groups of transmission lines, and the network device obtains 2Y TOAs. The network device may, for example, perform mean operation on the 2Y TOAs to obtain two TOAs, and then send the two TOAs to the core network device. Alternatively, the network device may also directly send the 2Y TOAs to the core network device without limitation.

[0236] S1704: The core network device determines the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path.

[0237] For example, the core network device may determine the position information of the terminal device according to the TOA corresponding to the first transmission path, the TOA corresponding to the fifth transmission path, the length of the first transmission line, and the transmission speed of the third signal in the first transmission line. The present embodiment does not limit the specific implementation process of the core network device for determining the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path.

[0238] S1705: The network device determines the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path.

[0239] For example, the network device may determine the position information of the terminal device according to the TOA corresponding to the first transmission path, the TOA corresponding to the fifth transmission path, the length of the first transmission line, and the transmission speed of the third signal in the first transmission line. The present embodiment does not limit the specific implementation process of the network device for determining the position information of the terminal device according to the TOA corresponding to the first transmission path and the TOA corresponding to the fifth transmission path.

[0240] In the third positioning method described above, even if there is only one network device and one transmission line, two TOAs can be obtained, so that the positioning of the terminal device can be realized, and the method can be applied to various application scenarios.

[0241] The above describes the uplink positioning based on the communication system 1600. Next, the downlink positioning based on the communication system 1600 is described.

[0242] Figure 18 For example, a flowchart of the fourth positioning method provided by the present embodiment is shown. The fourth positioning method is applied to Figure 16 The communication system 1600 shown in the figure. Moreover, the present embodiment is a downlink positioning scenario. As shown inFigure 18 As shown, the method can include the following.

[0243] S1801: The network device sends an eighth signal.

[0244] Correspondingly, the terminal device receives a ninth signal and a fourteenth signal.

[0245] In this embodiment, the eighth signal sent by the network device can be transmitted from the first port to the first reference location and then transmitted wirelessly to the terminal device; and the eighth signal sent by the network device can be transmitted from the first port to the third reference location and then transmitted wirelessly to the terminal device. That is, the eighth signal sent by the network device can reach the terminal device through two transmission paths (e.g., the seventh transmission path and the eleventh transmission path). The eighth signal, the first reference location, the third reference location, and the seventh transmission path are described above and will not be described here.

[0246] The eleventh transmission path can include a transmission path between the first port and the third reference location. In a possible implementation, the eleventh transmission path can further include a transmission path between the third reference location and the terminal device. In other words, the eleventh transmission path can be a transmission path between the first port and the third reference location, which can be similar to the eighth transmission path in the embodiment shown above; or the eleventh transmission path can be a transmission path between the first port and the third reference location and a transmission path between the third reference location and the terminal device. Figure 11

[0247] For ease of understanding, the signal received by the terminal device through the seventh transmission path is referred to as the ninth signal in the embodiments of the present application, and correspondingly, the ninth signal can be the signal of the eighth signal reaching the terminal device through the seventh transmission path; and the signal received by the terminal device through the eleventh transmission path is referred to as the fourteenth signal, and correspondingly, the fourteenth signal can be the signal of the eighth signal reaching the terminal device through the eleventh transmission path.

[0248] It can be understood that S1801 can also be expressed as S1801a and S1801b, Figure 18 which are exemplified in S1801a and S1801b. In S1801a, the network device sends the eighth signal, and the terminal device receives the ninth signal through the seventh transmission path; in S1801b, the network device sends the eighth signal, and the terminal device receives the fourteenth signal through the eleventh transmission path.

[0249] S1802: The terminal device determines the TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path according to the ninth signal and the fourteenth signal.

[0250] ​The TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path can be used to determine the position information of the terminal device. For example, the terminal device can determine the TOA corresponding to the seventh transmission path according to the ninth signal, and determine the TOA corresponding to the eleventh transmission path according to the fourteenth signal. The TOA corresponding to the seventh transmission path can be understood as the time difference between the time when the eighth signal is sent by the network device and the time when the eighth signal reaches the terminal device through the seventh transmission path. The TOA corresponding to the eleventh transmission path can be understood as the time difference between the time when the eighth signal is sent by the network device and the time when the eighth signal reaches the terminal device through the eleventh transmission path. The specific implementation process of the terminal device determining the TOA is not limited in the embodiments of the present application.

[0251] In a possible implementation, the terminal device can determine the TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path according to the sixth information, the ninth signal and the fourteenth signal. The sixth information can also be referred to as a fingerprint information base of the seventh transmission path and the eleventh transmission path, or a fingerprint information base, and the name of the sixth information is not limited in the embodiments of the present application. The sixth information can include the power value corresponding to the seventh transmission path and the power value corresponding to the eleventh transmission path; or the sixth information can include the power ratio between the seventh transmission path and the eleventh transmission path; or the sixth information can include the power value corresponding to the seventh transmission path and the power value corresponding to the eleventh transmission path, and the power ratio between the seventh transmission path and the eleventh transmission path. For description of the sixth information, please refer to the description of the first information described above, and details are not repeated. In the above implementation, the terminal device can use the sixth information to assist in determining two TOAs for positioning, so as to avoid the problem that the terminal device cannot obtain two TOAs when the terminal device is close to the network device, and cannot realize the positioning of the terminal device, and avoid the problem that the terminal device cannot obtain two TOAs when the terminal device is close to the end of the interval segment where the transmission line is deployed, and cannot realize the positioning of the terminal device.

[0252] In a possible implementation, if Figure 16The communication system 1600 shown includes Y groups of transmission lines, then in S1801, the terminal device can receive Y ninth signals and Y fourteenth signals, and in S1802, the terminal device can determine TOAs corresponding to Y seventh transmission paths and TOAs corresponding to Y eleventh transmission paths according to the Y ninth signals and the Y fourteenth signals. Wherein, Y is an integer greater than 1. The deployment mode of the Y groups of transmission lines is described above, and will not be repeated here. Further, the terminal device can perform mean operation on the TOAs corresponding to the Y seventh transmission paths to obtain a TOA corresponding to the seventh transmission path, and perform mean operation on the TOAs corresponding to the Y eleventh transmission paths to obtain a TOA corresponding to the eleventh transmission path, without limitation. In this implementation mode, the terminal device can obtain 2Y TOAs, which can improve the positioning accuracy.

[0253] Optionally, the fourth positioning method can further include S1803 and S1804, Figure 18 The position information of the terminal device can be determined by the core network device.

[0254] S1803: The terminal device sends the TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path to the core network device.

[0255] Correspondingly, the core network device receives the TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path from the terminal device.

[0256] The core network device may, for example, be an LMF network element, but is not limited thereto. For example, the terminal device can send the TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path to the core network device through an LPP message or an RRC message. It should be understood that if Figure 16 The communication system 1600 shown includes Y groups of transmission lines, then in S1801, the terminal device can receive Y ninth signals and Y fourteenth signals, and in S1802, the terminal device can determine TOAs corresponding to Y seventh transmission paths and TOAs corresponding to Y eleventh transmission paths according to the Y ninth signals and the Y fourteenth signals. Wherein, Y is an integer greater than 1. The deployment mode of the Y groups of transmission lines is described above, and will not be repeated here. Further, the terminal device can perform mean operation on the TOAs corresponding to the Y seventh transmission paths to obtain a TOA corresponding to the seventh transmission path, and perform mean operation on the TOAs corresponding to the Y eleventh transmission paths to obtain a TOA corresponding to the eleventh transmission path, without limitation. In this implementation mode, the terminal device can obtain 2Y TOAs, which can improve the positioning accuracy.

[0257] S1804: The core network device determines the position information of the terminal device according to the TOA corresponding to the seventh transmission path and the TOA corresponding to the eleventh transmission path.

[0258] For example, the core network device can determine the location information of the terminal device based on the TOA corresponding to the seventh transmission path, the TOA corresponding to the eleventh transmission path, the length of the first transmission line, and the transmission speed of the eighth signal in the first transmission line. This application embodiment does not limit the specific implementation process of the core network device determining the location information of the terminal device based on the TOA corresponding to the seventh and eleventh transmission paths.

[0259] In the fourth positioning method mentioned above, even if there is only one network device and one transmission line, two TOAs can be obtained, thereby enabling the positioning of the terminal device and making it applicable to a variety of application scenarios.

[0260] exist Figure 16 In the communication system 1600 shown, the other end of the first transmission line (i.e., the end not connected to the first port) can be connected to a load. In another possible implementation, the network device may further include a second port, to which the other end of the first transmission line can also be connected, such as... Figure 19 As shown.

[0261] Please see Figure 19 This is a schematic diagram of the architecture of a communication system 1900 provided in an embodiment of this application. The communication system 1900 may include a network device, one or more terminal devices, and at least one transmission line. Figure 19 The example is illustrated using a network device, a terminal device, and a transmission line (referred to as the first transmission line). And, Figure 19 The first transmission line is represented by a thick black line. The network device includes multiple ports, two of which are designated as the first port and the second port. Figure 19 The example shown is a network device with two ports. Figure 19 As shown, the first port of the network device is connected to one end of the first transmission line, and the other end of the first transmission line is connected to the second port of the network device. The first transmission line is bent and deployed in parallel as a dual transmission line. Optionally, the first transmission line can be a leaky cable or a waveguide. For details on parallel deployment, please refer to the foregoing description; it will not be repeated here.

[0262] It should be noted that the communication system 1900 can further include more transmission lines. For example, the network device can be connected with M groups of transmission lines (M is an integer greater than 1), and each group of transmission lines includes one transmission line, which can be deployed in the manner of the first transmission line. For example, the network device can further include a third port and a fourth port, the third port is connected with one end of a third transmission line, the other end of the third transmission line is connected with the fourth port, and the third transmission line is folded and deployed in the form of a double transmission line. The third transmission line can be described with reference to the first transmission line, and will not be described herein again. For the sake of brevity, the network device connected with one group of transmission lines will be described hereinafter.

[0263] It should be understood that the communication system 1900 can further include other devices, components, modules, or network elements not mentioned, or can only include part of the devices, components, or modules mentioned in the embodiments, without limitation. For example, the communication system 1900 can further include a core network element and a LCS client (and / or an AF), which will be described with reference to the embodiments shown in Figure 1 The description of the embodiments shown will not be described herein again.

[0264] In a possible implementation, based on the communication system 1900 shown in Figure 19 The third positioning method can further include that the network device can further receive a seventh signal and a fifth signal. For example, S1701 can be replaced with: the terminal device sends a third signal; and correspondingly, the network device receives the first signal, the sixth signal, the seventh signal, and the fifth signal. In this implementation, the other end of the first transmission line is connected with the second port of the network device, and then the third signal sent by the terminal device can reach the network device through another two transmission paths (referred to as a sixth transmission path and a fourth transmission path) in addition to the first transmission path and the fifth transmission path. Specifically, the third signal sent by the terminal device can be transmitted wirelessly to a first reference position and then transmitted from the first reference position to the first port; the third signal sent by the terminal device can be transmitted wirelessly to a third reference position and then transmitted from the third reference position to the first port; the third signal sent by the terminal device can be transmitted wirelessly to the third reference position and then transmitted from the third reference position to the second port; and the third signal sent by the terminal device can be transmitted wirelessly to the first reference position and then transmitted from the first reference position to the second port. The first reference position, the third reference position, and the fourth transmission path will be described with reference to the foregoing content, and will not be described herein again.

[0265] The sixth transmission path can include a transmission path between the third reference position and the second port. In one possible implementation, the sixth transmission path can also include a transmission path between the terminal device and the third reference position. In other words, the sixth transmission path can be a transmission path from the third reference position to the second port, which can be similar to the third transmission path in the embodiment shown in FIG. 7; or the sixth transmission path can be a transmission path from the terminal device to the third reference position and from the third reference position to the second port. Figure 14

[0266] For ease of understanding, the signal received by the network device through the sixth transmission path in the embodiments of the present application is referred to as a seventh signal, and correspondingly, the seventh signal can be the signal of the third signal reaching the second port through the sixth transmission path; and the signal received by the network device through the fourth transmission path is referred to as a fifth signal, and correspondingly, the fifth signal can be the signal of the third signal reaching the second port through the fourth transmission path.

[0267] Further, the network device can determine the TOA corresponding to the sixth transmission path and the TOA corresponding to the fourth transmission path according to the seventh signal and the fifth signal, and the TOA corresponding to the sixth transmission path and the TOA corresponding to the fourth transmission path are used to determine the position information of the terminal device. Exemplarily, S1702 can be replaced by: the network device determines the TOA corresponding to the first transmission path, the TOA corresponding to the fifth transmission path, the TOA corresponding to the sixth transmission path and the TOA corresponding to the fourth transmission path according to the first signal, the sixth signal, the seventh signal and the fifth signal. For example, the network device determines the TOA corresponding to the first transmission path according to the first signal, determines the TOA corresponding to the fifth transmission path according to the sixth signal, determines the TOA corresponding to the sixth transmission path according to the seventh signal, and determines the TOA corresponding to the fourth transmission path according to the fifth signal.

[0268] ​In an example, the network device can determine the TOA corresponding to the sixth transmission path and the TOA corresponding to the fourth transmission path according to the seventh information, the seventh signal and the fifth signal. The seventh information can also be referred to as a fingerprint information base of the sixth transmission path and the fourth transmission path, or a fingerprint information base, etc. The name of the seventh information in the embodiments of the present application is not limited. The seventh information can include the power value corresponding to the sixth transmission path and the power value corresponding to the fourth transmission path; or the seventh information can include the power ratio between the sixth transmission path and the fourth transmission path; or the seventh information can include the power value corresponding to the sixth transmission path and the power value corresponding to the fourth transmission path, and the power ratio between the sixth transmission path and the fourth transmission path. The description of the seventh information can refer to the description of the first information above, and will not be repeated. Optionally, the seventh information can be the same as the second information, or can be different. In the above example, the network device can use the seventh information to assist in determining two TOAs for positioning, so as to avoid the problem that the positioning of the terminal device cannot be implemented due to the inability to obtain two TOAs when the terminal device is close to the network device, and avoid the problem that the positioning of the terminal device cannot be implemented due to the inability to obtain two TOAs when the terminal device is close to the end of the interval segment of the transmission line.

[0269] In an example, if Figure 19 As shown in the communication system 1900, the network device can receive M first signals, M sixth signals, M seventh signals and M fifth signals. And the network device can determine the TOA corresponding to the M first transmission paths, the TOA corresponding to the M fifth transmission paths, the TOA corresponding to the M sixth transmission paths and the TOA corresponding to the M fourth transmission paths according to the M first signals, the M sixth signals, the M seventh signals and the M fifth signals. Wherein, M is an integer greater than 1. The deployment mode of the M groups of transmission lines can refer to the foregoing content, and will not be repeated. Further, the network device can perform mean operation on the TOA corresponding to each transmission path, which can refer to the foregoing content, and will not be repeated. Through the example, the network device can obtain 4M TOAs, which can improve the positioning accuracy.

[0270] In this implementation, the network device can send the TOA corresponding to the first transmission path, the TOA corresponding to the fifth transmission path, the TOA corresponding to the sixth transmission path, and the TOA corresponding to the fourth transmission path to the core network device. Correspondingly, the core network device determines the location information of the terminal device based on the TOA corresponding to the first, fifth, sixth, and fourth transmission paths. Alternatively, the network device can perform an average operation on the TOA corresponding to the first and sixth transmission paths, and also perform an average operation on the TOA corresponding to the fifth and fourth transmission paths to obtain two TOAs, which are then sent to the core network device. Correspondingly, the core network device determines the location information of the terminal device based on these two TOAs. Alternatively, the network device can determine the location information of the terminal device based on the TOA corresponding to the first, fifth, sixth, and fourth transmission paths. For a detailed implementation process, please refer to S1703, S1704, and S1705, which will not be repeated here.

[0271] In the above implementation, even with only one network device and one transmission line, at least four TOAs can be obtained, thereby enabling the positioning of the terminal device, improving positioning accuracy, and making it applicable to a variety of application scenarios.

[0272] In another possible implementation, based on Figure 19 The communication system 1900 shown above, in its fourth positioning method, may further include: the network device may transmit an eleventh signal; correspondingly, the terminal device may receive a fifteenth signal and a thirteenth signal. Exemplarily, S1801 may be replaced by: the network device transmitting an eighth signal and an eleventh signal; correspondingly, the terminal device receiving a ninth signal, a fourteenth signal, a fifteenth signal, and a thirteenth signal. The eleventh signal may be a positioning reference signal or a pilot signal; the specific implementation of the eleventh signal is not limited in this embodiment. Optionally, the eleventh signal and the eighth signal may be the same or different.

[0273] In the present implementation, the other end of the first transmission line is connected to the second port of the network device, then the eighth signal sent by the network device through the first port can reach the terminal device through the seventh transmission path and the eleventh transmission path, and the eleventh signal sent by the network device through the second port can reach the terminal device through another two transmission paths (such as the twelfth transmission path and the tenth transmission path). Specifically, the eighth signal sent by the network device can be transmitted from the first port to the first reference position, and then reach the terminal device through wireless transmission; the eighth signal sent by the network device can be transmitted from the first port to the third reference position, and then reach the terminal device through wireless transmission; the eleventh signal sent by the network device can be transmitted from the second port to the third reference position, and then reach the terminal device through wireless transmission; and the eleventh signal sent by the network device can be transmitted from the second port to the first reference position, and then reach the terminal device through wireless transmission. Wherein, the first reference position, the third reference position, the seventh transmission path, the eleventh transmission path and the tenth transmission path please refer to the foregoing content, and will not be repeated here.

[0274] The twelfth transmission path can include the transmission path between the second port and the third reference position. In a possible implementation, the twelfth transmission path can further include the transmission path between the third reference position and the terminal device. In other words, the twelfth transmission path can be the transmission path between the second port and the third reference position, which can be similar to the ninth transmission path shown in the embodiment described above; or the twelfth transmission path can be the transmission path between the second port and the third reference position and the transmission path between the third reference position and the terminal device. Figure 15

[0275] For the convenience of understanding, the signal received by the terminal device through the twelfth transmission path is referred to as the fifteenth signal in the embodiments of the present application, and accordingly the fifteenth signal can be the signal of the eleventh signal reaching the second port through the twelfth transmission path; and the signal received by the terminal device through the tenth transmission path is referred to as the thirteenth signal, and accordingly the thirteenth signal can be the signal of the eleventh signal reaching the second port through the tenth transmission path.

[0276] ​Further, the terminal device determines the TOA corresponding to the twelfth transmission path and the TOA corresponding to the tenth transmission path according to the fifteenth signal and the thirteenth signal, and the TOA corresponding to the twelfth transmission path and the TOA corresponding to the tenth transmission path are used to determine the position information of the terminal device. For example, S1802 can be replaced by: the terminal device determines the TOA corresponding to the seventh transmission path, the TOA corresponding to the eleventh transmission path, the TOA corresponding to the twelfth transmission path and the TOA corresponding to the tenth transmission path according to the ninth signal, the fourteenth signal, the fifteenth signal and the thirteenth signal. For example, the terminal device determines the TOA corresponding to the seventh transmission path according to the ninth signal, determines the TOA corresponding to the eleventh transmission path according to the fourteenth signal, determines the TOA corresponding to the twelfth transmission path according to the fifteenth signal, and determines the TOA corresponding to the tenth transmission path according to the thirteenth signal.

[0277] In an example, the terminal device can determine the TOA corresponding to the twelfth transmission path and the TOA corresponding to the tenth transmission path according to the eighth information, the fifteenth signal and the thirteenth signal. The eighth information can also be referred to as a fingerprint information base of the twelfth transmission path and the tenth transmission path, or a fingerprint information base, etc., and the name of the eighth information in the embodiments of the present application is not limited. The eighth information can include the power value corresponding to the twelfth transmission path and the power value corresponding to the tenth transmission path; or the eighth information can include the power ratio between the twelfth transmission path and the tenth transmission path; or the eighth information can include the power value corresponding to the twelfth transmission path and the power value corresponding to the tenth transmission path, and the power ratio between the twelfth transmission path and the tenth transmission path. For details of the eighth information, please refer to the description of the first information above, which will not be repeated here. Optionally, the eighth information can be the same as the sixth information, or can be different. In the above example, the terminal device can use the eighth information to assist in determining two TOAs for positioning, so as to avoid the problem that the positioning of the terminal device cannot be realized due to the inability to obtain two TOAs when the network device is close to the terminal device, and avoid the problem that the positioning of the terminal device cannot be realized due to the inability to obtain two TOAs when the network device is close to the end of the interval segment of the transmission line.

[0278] In an example, if Figure 19The communication system 1900 shown includes N groups of transmission lines, so that the terminal device can receive N ninth signals, N fourteenth signals, N fifteenth signals, and N thirteenth signals. And the terminal device can determine the TOA corresponding to the N seventh transmission paths, the TOA corresponding to the N eleventh transmission paths, the TOA corresponding to the N twelfth transmission paths, and the TOA corresponding to the N tenth transmission paths according to the N ninth signals, the N fourteenth signals, the N fifteenth signals, and the N thirteenth signals. Wherein, N is an integer greater than 1. The deployment mode of the N groups of transmission lines is described above, and will not be described here. Further, the terminal device can perform mean operation on the TOA corresponding to each transmission path, which is described above, and will not be described here. Through the present example, the terminal device can obtain 4N TOAs, which can improve the positioning accuracy.

[0279] In the present implementation, the terminal device can send the TOA corresponding to the seventh transmission path, the TOA corresponding to the eleventh transmission path, the TOA corresponding to the twelfth transmission path, and the TOA corresponding to the tenth transmission path to the core network device; correspondingly, the core network device determines the position information of the terminal device according to the TOA corresponding to the seventh transmission path, the TOA corresponding to the eleventh transmission path, the TOA corresponding to the twelfth transmission path, and the TOA corresponding to the tenth transmission path. Alternatively, the terminal device can also perform mean operation on the TOA corresponding to the seventh transmission path and the TOA corresponding to the twelfth transmission path, and perform mean operation on the TOA corresponding to the fourteenth transmission path and the TOA corresponding to the tenth transmission path, to obtain two TOAs, and send the two TOAs to the core network device; correspondingly, the core network device determines the position information of the terminal device according to the two TOAs. The specific implementation process is described in the content of S1803 and S1804, and will not be described here.

[0280] In the above implementation, even if there is only one network device and one transmission line, at least four TOAs can be obtained, so that the positioning of the terminal device can be realized, the positioning accuracy can be improved, and it can be applied to various application scenarios.
