[0013] In order to allow those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in one or more embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative efforts fall within the scope of protection of the present application.

[0014] The terms "first," "second," etc., used herein and in the claims are used to distinguish between similar aspects and are not intended to describe a particular order or chronology. It will be understood that the data used in this manner are interchangeable where appropriate, so that the embodiments of the present application may be performed in orders other than those illustrated or described herein. It should be noted that "and / or" in the present application and in the claims indicates at least one of the connected objects, and the character " / " generally indicates that the related objects before and after are in an "or" relationship.

[0015] In order to reduce the number of network side devices (for example, base stations) required when locating a terminal device, the present application provides a terminal device location method and a network side device, which will be described below with reference to the drawings.

[0016] In the embodiments of the present application, the network side device applied to terminal device positioning includes multiple antenna ports, and the network side device is a 5G base station for example, and the network side device may be a base station including a 4TR antenna or an 8TR antenna. Alternatively, the antenna model number of the network side device required in the embodiments of the present application is NTR, where N is any positive integer and TR is an abbreviation for Transmit and Receive.

[0017] As shown in FIG. 1, in order to reduce the number of network side devices (e.g., base stations) required for terminal device positioning, in an embodiment of the present application, for a network side device including an NTR antenna panel, one antenna panel is remotely installed as a single TR antenna panel from each antenna port, and the remotely installed single TR antenna is connected to the network side device body via a signal feeder line. That is, the conventional NTR antenna system is replaced with a multiple single TR antenna system. In this way, one network side device can be configured with remotely installed antennas for N antenna ports, and one remotely installed single TR antenna is equivalent to one network side device for measurement, and one measurement report for the terminal device is measured and obtained. This reduces the number of network side devices required for terminal device positioning and reduces the power consumption of the network side devices. In this way, replacing network side devices that previously required installation with antennas can also reduce the installation costs of network side devices required for positioning.

[0018] In the remote antenna installation scheme shown in FIG. 1, one network side device originally generates one set of measurement reports analyzing the probe signal from the target terminal device, which can be expressed as follows: TIFF2026506339000002.tif5170

[0019] Here, t represents the arrival delay, and rsrp represents the received power of the reference signal. After constructing N sets of single TR antennas, each set of single antennas is a set of antenna radiation patterns (Antenna Radiation Patterns, ARPs) and measures them independently, so that four sets of measurement reports can be obtained as follows: TIFF2026506339000003.tif46170

[0020] This allows the location information of the target terminal to be calculated using N sets of positioning measurement reports from one base station.

[0021] The terminal device positioning method according to the present embodiment may be used for indoor positioning, for example, positioning based on an indoor 5G pico site, Bluetooth, or Ultra Wideband (UWB). The terminal device positioning method according to the present embodiment may also be used for outdoor positioning, for example, positioning based on an outdoor 5G macro base station. That is, in the present embodiment, the network side device may be any one of a 5G pico site, a Bluetooth device, a UWB device, and a 5G macro base station.

[0022] In the embodiment of the present application, the network side device receives the probe signal and calculates measurement parameters such as arrival delay, arrival angle, and received signal strength of the received probe signal within the network side device (i.e., the main body of the network side device). The terminal device transmits the probe signal, and multiple remotely installed single TR antennas receive the same uplink sounding measurement signal of the terminal device.

[0023] Here, the arrival delay may include, but is not limited to, a timing advance amount TA. The received signal strength may include, but is not limited to, at least one of Reference Signal Receiving Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Received Quality (RSRQ), and Signal Interference Noise Ratio (SINR). The probe signal may include, but is not limited to, one of signals such as an uplink Sounding Reference Signal (SRS) and a single frequency sine wave signal.

[0024] Based on the network side equipment shown in Figure 1, the present application provides a terminal equipment positioning method, which can be applied to a network side equipment including multiple remotely installed single TR antennas as shown in Figure 1, where the multiple single TR antennas are connected to the network side equipment body via signal feeder lines, and the multiple single TR antennas are arranged at different positions in the target positioning scene, and as shown in Figure 2, the method may include the following steps:

[0025] Step 201: Measure a target terminal using the multiple single TR antennas respectively, and obtain multiple measurement reports for the target terminal, and one measurement report is obtained correspondingly by measuring using one single TR antenna, and the measurement report includes measurement values ​​of specified parameters for determining the location of the target terminal.

[0026] Specifically, step 201 may include receiving, via the plurality of single TR antennas, probe signals transmitted by the target terminal, respectively, analyzing the probe signals received by the plurality of single TR antennas, respectively, and generating the plurality of measurement reports. Since the method of analyzing the received probe signals by the network side device is a conventional technique, it will not be further described in this specification.

[0027] Here, the specified parameters may include, but are not limited to, at least one of arrival delay, arrival angle, and received signal strength.

[0028] Step 202: Determine location information of the target terminal based on the measurement values ​​of the specified parameters in the plurality of measurement reports.

[0029] In the embodiment of the present application, the target positioning scene is mainly an indoor positioning scene. Specifically, the target positioning scene may include the following three situations:

[0030] First type of applicable scene: A scene without any obstruction by an obstacle, that is, a LOS (Line of Sight) scene.

[0031] The second type of application scene: a scene including multiple compartments, such as a multi-story building, a conference room including multiple rooms, etc. Optionally, the multiple compartments may further include a line-of-sight scene, i.e., the interior of a compartment belongs to the line-of-sight scene, see the third type of application scene below. Of course, the multiple compartments may also include non-line-of-sight scenes, such as compartments with irregular shapes or obstructions.

[0032] The third type of application scene: the first type of application scene + the second type of application scene, i.e., LOS scene + multiple compartments.

[0033] Furthermore, those skilled in the art can further develop the layout method and positioning principle for multiple remotely installed single TR antennas outdoors based on the layout method and positioning principle for multiple remotely installed single TR antennas indoors shown in the embodiments of the present application.

[0034] The specified parameters used for positioning vary depending on the application scenario, and will be described below separately for each scenario.

[0035] 1) First application scene (LOS scene) This scene is an open, unobstructed scene, such as a rectangular empty room. Note that it is not a non-LOS scene, i.e., an area with irregular shape or obstructions. TIFF2026506339000004.tif5170 (buildings, train stations, airport terminals, etc. with an obstacle in the center) Regarding the LOS scene, it can be divided into multiple regions (sections) based on the LOS requirements, and each region can be set as an LOS scene. In this scene, the number of single TR antennas is two or more.

[0036] In this scenario, a delay-based positioning method may be adopted, that is, the specified parameters include arrival delay.

[0037] In this scenario, the placement principles for a single TR antenna include:

[0038] a. Arrange multiple remotely installed single TR antennas at the boundary locations (e.g., corner locations) of the scene, respectively, and ensure that the target area for positioning is located within the coverage area of ​​the multiple remotely installed single TR antennas. b. When the number of remotely installed multiple single TR antennas is greater than three, ensure that the target users within the coverage area of ​​the multiple single TR antennas can directly observe the multiple single TR antennas when installed. c. When installing, keep remotely installed multiple single TR antennas as far away from obstacles as possible, typically within 2-3 meters of any obstacle.

[0039] As shown in Figure 3, if the target positioning scene is an open, rectangular room with no indoor obstacles, a 4TR network side device is used, and four remotely installed single TR antennas are placed at the four corners of the room, respectively, and the four single TR antennas are located at a predetermined distance from the wall.

[0040] Correspondingly, step 202 may include determining location information of the target terminal based on location information of the plurality of single TR antennas and measurement values ​​of arrival delays in the plurality of measurement reports.

[0041] The length of the signal feeder line connecting the remotely installed single TR antenna and the network side equipment main body affects the arrival delay of the probe signal (the probe signal propagates with a certain delay (first propagation delay) along the signal feeder line). Therefore, to offset the propagation delay along the signal feeder line, the embodiments of this application provide two methods.

[0042] Solution 1: The lengths of the signal feeder lines connecting different single TR antennas among the plurality of single TR antennas to the network side device body are the same, and the specific length is the length of the signal feeder line required for the single TR antenna among the plurality of single TR antennas that is farthest from the network side device body.

[0043] In solution 1, determining the location information of the target terminal based on the location information of the multiple single TR antennas and the measured arrival delays in the multiple measurement reports as described above may specifically include determining the location information of the target terminal based on the location information of the multiple single TR antennas, the measured arrival delays in the multiple measurement reports, and a delay-based positioning method, where the delay-based positioning method includes an uplink time of arrival (UTOA) positioning method or an uplink time difference of arrival (UTDOA) positioning method.

[0044] As can be understood, by selecting signal feeder lines of the same length, when constructing the UTOA or UTDOA positioning equation, the propagation delay of the probe signal in the signal feeder line can be offset, and the constructed delay difference can be ensured to be the distance delay difference between the target terminal and the two ARPs (single TR antennas).

[0045] In method 1, taking the arrival delay as an example when it is TA, for the probe signal from the target terminal to each single TR antenna, multiple measurement reports corresponding to multiple base stations can be measured through each single TR antenna, and the measurement information in these multiple measurement reports can be expressed as follows:

[0046] TIFF2026506339000005.tif31170

[0047] where: TIFF2026506339000006.tif6170 represents the coordinates where the i-th single TR antenna is located, and TAi represents the timing advance amount corresponding to the i-th single TR antenna, and ∇ t represents the propagation delay of the probe signal in the signal feeder line, and t i represents the propagation delay of the probe signal transmitted by the target terminal propagating from the target terminal to the i-th single TR antenna, where i=0, 1, 2, ..., N-1.

[0048] Solution 2: The lengths of the signal feeder lines connecting different single TR antennas among the plurality of single TR antennas and the network side device main body are the same or different.

[0049] In method 2, determining the location information of the target terminal based on the location information of the multiple single TR antennas and the measured arrival delays in the multiple measurement reports as described above may specifically include: for any one of the multiple single TR antennas, determining a first propagation delay in the signal feeder line corresponding to the single TR antenna of the probe signal received by the single TR antenna based on the length of the signal feeder line between the single TR antenna and the network side device main body; determining a second propagation delay (arrival delay - first propagation delay = second propagation delay) of the probe signal received by the single TR antenna propagating from the target terminal to the single TR antenna based on the measured arrival delays in the measurement report corresponding to the single TR antenna and the first propagation delay; and determining the location information of the target terminal based on the location information of the multiple single TR antennas, the second propagation delays corresponding to the multiple single TR antennas and a delay-based positioning method, wherein the delay-based positioning method may include UTOA or UTDOA.

[0050] In method 2, taking the arrival delay as an example, for the probe signal from the target terminal to each single TR antenna, the propagation delay of the probe signal in the signal feeder line is first calculated, and the received delay is offset, thereby obtaining the delay of the probe signal propagating between the target terminal and Arp (single TR antenna). In method 2, the length of the signal feeder line corresponding to each single TR antenna needs to be recorded during the installation stage, and transmitted to the network side device via the interface as a positioning algorithm parameter to calculate the delay offset information. The formula for calculating the propagation delay (first propagation delay) of the probe signal in the signal feeder line according to the distance is as follows: TIFF2026506339000007.tif9170

[0051] where L i is the length of the signal feeder line between the i-th single TR antenna and the network side device body, and c is the speed of light.

[0052] In method 2, multiple measurement reports corresponding to multiple base stations can be measured through each single TR antenna, and the measurement information in the multiple measurement reports can be expressed as follows: TIFF2026506339000008.tif32170

[0053] where: TIFF2026506339000009.tif7170 represents the coordinates where the i-th single TR antenna is located, and TA i represents the timing advance amount corresponding to the i-th single TR antenna, and ∇t i represents the propagation delay (first propagation delay) in the signal feeder line between the i-th single TR antenna of the probe signal and the network side device body, and t i represents the propagation delay (second propagation delay) of the probe signal transmitted by the target terminal propagating from the target terminal to the i-th single TR antenna, where i=0, 1, 2, ..., N-1.

[0054] After determining the coordinates where each single TR antenna is located and the propagation delay corresponding to each single TR antenna using the above method 1 or method 2, if the coordinates of the target terminal are [X, Y, Z] and the position of the target terminal is determined using UTDO, the following equation can be constructed. TIFF2026506339000010.tif34170

[0055] If the number of remotely installed single TR antennas exceeds four, the above method can construct at least three sets of equations, and the coordinates [X, Y, Z] of the target terminal can be solved using the least squares method, thereby achieving the goal of using one base station to locate the target terminal.

[0056] The process of constructing an equation using TOA can be referred to in the related art, and will not be further described in the embodiments of the present application.

[0057] Optionally, in a first application scenario, the location of the target terminal may be determined based on an angle-of-arrival (AOA) method, and the specified parameters include an angle of arrival. In this case, step 202 may include determining location information of the target terminal based on location information of the plurality of single TR antennas, the measurement values ​​of the angles of arrival in the plurality of measurement reports, and AOA.

[0058] Similarly, the process of constructing an equation using AOA can be referred to in the related art, and will not be further described in the embodiments of the present application.

[0059] Optionally, in a first application scenario, the location of the target terminal may be comprehensively determined by combining a delay-based positioning method and an angle-of-arrival (AOA) positioning method, in which the specified parameters include arrival delay and arrival angle, and determining the location information of the target terminal based on the measured values ​​of the specified parameters in the plurality of measurement reports includes determining the location information of the target terminal based on the location information of the plurality of single TR antennas, the measured values ​​of the arrival delay and arrival angle in the plurality of measurement reports, and an uplink time-of-arrival positioning method UTDOA and an angle-of-arrival positioning method AOA, or determining the location information of the target terminal based on the location information of the plurality of single TR antennas, the measured values ​​of the arrival delay and arrival angle in the plurality of measurement reports, and an uplink time-difference-of-arrival positioning method UTDOA and an angle-of-arrival positioning method AOA.

[0060] In addition, when determining the location information of the target terminal comprehensively based on a delay-based positioning method and an angle-of-arrival (AOA) positioning method, equations relating to the coordinates of the target terminal can be constructed based on the arrival delay and the angle of arrival, respectively, and then simultaneously solved to obtain the coordinate information of the target terminal, and this will not be further described in the embodiments of the present application.

[0061] 2) The second application scene (a scene containing multiple compartments) The second application scenario may be a scenario involving multiple sections, such as a scenario involving multiple rooms or multiple floors. In a scenario involving multiple floors, it becomes more difficult to offset delays using signal feeder lines of the same length, while the accuracy of the interval delays is poor, resulting in increased errors in positioning accuracy. Therefore, in this scenario, a positioning method based on signal reception strength can be selected for positioning, improving accuracy.

[0062] In this scenario, at least one single TR antenna is arranged in one section, and the specified parameters of the at least one single TR antenna in one section include received signal strength. For example, specific arrangement principles of the single TR antenna may include:

[0063] a. For a scene including multiple rooms (e.g., a scene including multiple offices), one remotely installed single TR antenna is placed in the central area of ​​each section (e.g., a room), and as shown in Figure 4, single TR antenna panel 1, single TR antenna panel 2, single TR antenna panel 3, and single TR antenna panel 4 are placed correspondingly in the central areas of sections 1, 2, 3, and 4, respectively, and the network side equipment main body may be placed in any one of these four sections, or in another room other than these sections, and the network side equipment main body may be connected to the remotely installed single TR antenna via a signal feeder line.

[0064] b. For a scene spanning multiple floors, one remotely installed single TR antenna is placed on each floor, and as shown in Figure 5A, single TR antenna panel 1, single TR antenna panel 2, single TR antenna panel 3 and single TR antenna panel 4 are placed correspondingly in the central areas of the ceilings of the first, second, third and fourth floors, respectively, and the network side equipment main body may be placed on any one of these four floors, or may be placed at a location other than these floors, and the network side equipment main body may be connected to the remotely installed single TR antenna via a signal feeder line.

[0065] In the above arrangement, multiple measurement reports corresponding to multiple base stations can be measured through each single TR antenna, and the measurement information in the multiple measurement reports can be expressed as follows: TIFF2026506339000011.tif24170

[0066] where: TIFF2026506339000012.tif7170 represents the coordinates where the i-th single TR antenna is located, and rsrp i represents the received signal strength corresponding to the i-th single TR antenna, and ∇d i represents the path loss in the signal feeder line between the i-th single TR antenna of the probe signal and the network side device itself, and d i represents the strength value of the actual received signal of the probe signal received by the i-th single TR antenna propagating from the target terminal to the i-th single TR antenna, where i=0, 1, 2, . . . , N-1.

[0067] where: TIFF2026506339000013.tif5170 represents frequency, m represents frequency loss decibel coefficient, n represents distance loss decibel coefficient, L i represents the length of the signal feeder line between the i-th single TR antenna and the network side equipment body, and A represents the circuit attenuation in decibels.

[0068] In light of this, as one example, step 202 may include searching a pre-configured fingerprint library based on the measurement values ​​of received signal strength in the multiple measurement reports to obtain location information of the target terminal, wherein the fingerprint library stores a correspondence between coordinate information of each position in the target positioning scene and received signal strength values ​​from terminal equipment at that position received by the multiple single TR antennas, and the data in the fingerprint library is pre-measured.

[0069] As another example, step 202 may include determining location information of the target terminal based on location information of the plurality of single TR antennas and measurements of received signal strength in the plurality of measurement reports.

[0070] Specifically, determining the location information of the target terminal based on the location information of the multiple single TR antennas and the measured values ​​of received signal strength in the multiple measurement reports may include: for any one single TR antenna among the multiple single TR antennas, determining the path loss in the signal feeder line corresponding to the single TR antenna of the probe signal received by the single TR antenna based on the length of the signal feeder line between the single TR antenna and the network side device main body; determining the strength value of the actual received signal of the probe signal received by the single TR antenna propagating from the target terminal to the single TR antenna based on the measured values ​​of received signal strength in the measurement report corresponding to the single TR antenna and the path loss (see the above description for specific calculation formulas); and determining the location information of the target terminal based on the location information of the multiple single TR antennas and the strength values ​​of the actual received signal corresponding to the multiple single TR antennas.

[0071] Here, determining the location information of the target terminal based on the location information of the plurality of single TR antennas and the strength values ​​of the actual received signals corresponding to the plurality of single TR antennas may include determining the maximum value among the strength values ​​of the actual received signals corresponding to the plurality of single TR antennas, and determining the location of the section in which the single TR antenna corresponding to the maximum value is located as the target section in which the target terminal is located.

[0072] In a first example, the strength values ​​of the actual received signals corresponding to the plurality of single TR antennas may be directly compared to determine the maximum value among the strength values ​​of the actual received signals corresponding to the plurality of single TR antennas.

[0073] In the second example, the solution may be obtained by a function fitting method, and specifically, determining the maximum value among the strength values ​​of the actual received signals corresponding to the plurality of single TR antennas as described above may include the following steps:

[0074] Step 1: For any one of the multiple single TR antennas, determine the distance of the single TR antenna to the coordinate origin based on the coordinate information of the single TR antenna, where the coordinate origin is the origin of a predetermined coordinate system for representing the coordinates of each single TR antenna and the target terminal.

[0075] The formula for calculating the distance of the i-th single TR antenna relative to the coordinate origin can be expressed as: TIFF2026506339000014.tif9170 where [x i ,y i ,z i ] represents the coordinate of the i-th single TR antenna.

[0076] Optionally, the distances of the multiple single TR antennas relative to the coordinate origin may be sorted to facilitate subsequent function fitting.

[0077] Step 2: Construct an objective function for the distances of the multiple single TR antennas relative to the origin and the strength values ​​of the actual received signals corresponding to the multiple single TR antennas, where the objective function is a function of the strength values ​​of the actual received signals corresponding to the single TR antennas relative to the distance of the single TR antenna relative to the origin.

[0078] Here, the target function can be expressed as follows: TIFF2026506339000015.tif5170 where rsrp i represents the actual received signal strength value corresponding to the i-th single TR antenna.

[0079] Step 3: Determine the coordinate values ​​on the curve of the objective function of the plurality of single TR antennas.

[0080] Step 4: Construct a line graph based on the coordinate values ​​on the curve of the target function of the plurality of single TR antennas.

[0081] Specifically, by substituting the coordinates of the multiple single TR antennas into the target function, the strength values ​​of the actual received signals corresponding to the multiple single TR antennas can be solved, and by connecting the strength values ​​of the actual received signals corresponding to the multiple single TR antennas with a line, a line graph can be obtained.

[0082] Step 5: Determine the local maxima and / or maximum values ​​in the line graph.

[0083] Here, the maximum value and the maximum value can be expressed as follows: TIFF2026506339000016.tif10170

[0084] Step 6: The location of the section where the single TR antenna corresponding to the maximum value is located is determined as the location where the target terminal is located (target section).

[0085] Hereinafter, the process of determining the location of the target terminal using the second example above will be described by taking the application scenario shown in FIG. 5A as an example.

[0086] First step: For the application scenario shown in Figure 5A, one 4TR base station is selected and four single TR antenna panels are remotely installed. Since the positioning demand is to locate the floor where the target terminal is located, the remotely installed single TR antenna panels are placed in the center of the central ceiling of each of the four floors, and the base station is placed on the third floor.

[0087] Second step: The base station obtains the coordinate information and received signal strength measurement of each ARP measured by a single TR antenna panel as follows: TIFF2026506339000017.tif20170

[0088] Third step: Following the construction method of the target function in the second example above, Compose TIFF2026506339000018.tif5170.

[0089] Fourth step: The position data of each single TR antenna panel calculated based on the objective function is as follows: TIFF2026506339000019.tif23170

[0090] Step 5: A line graph is constructed based on the calculated position data of each single TR antenna panel (as shown in FIG. 5B). From FIG. 5B, it can be analyzed that the curve only has one local maximum and no maximum value, which indicates that the floor on which the target terminal is located is the floor on which ARP3 (single TR antenna panel 3) is located. As can be seen, the terminal positioning method according to the embodiment of the present application not only has a low algorithm complexity, but also reduces the cost of site construction and has high accuracy, making this method highly practical.

[0091] Optionally, in the above-mentioned second application scene, when at least two single TR antennas (corresponding to the first application scene superimposed on the second application scene) are arranged in the target area and the specified parameters of the at least two single TR antennas include at least one of arrival delay and arrival angle, the method shown in Figure 2 may further include determining location information of the target terminal in the target area based on location information of the at least two single TR antennas in the target area and measured values ​​of the arrival delay and / or the arrival angle in measurement reports corresponding to the at least two single TR antennas, and the target area is one of the multiple areas.

[0092] As an example, when at least two single TR antennas (corresponding to a first application scene superimposed on a second application scene) are arranged in the target area, and the specified parameters of the at least two single TR antennas further include arrival delay, the location information of the target terminal in the target area is determined based on the location information of the at least two single TR antennas in the target area and the measurement values ​​of the arrival delay in the measurement reports corresponding to the at least two single TR antennas and a delay-based positioning method, where the delay-based positioning method includes an uplink time-of-arrival positioning method UTOA or an uplink time difference of arrival positioning method UTDOA.

[0093] As another example, when at least two single TR antennas (corresponding to a first application scene superimposed on a second application scene) are arranged in the target area and the specified parameters of the at least two single TR antennas further include an angle of arrival, the location information of the target terminal in the target area is determined based on the location information of the at least two single TR antennas in the target area and the measurement values ​​of the angle of arrival in the measurement reports corresponding to the at least two single TR antennas and the angle of arrival positioning method AOA.

[0094] As another example, when at least two single TR antennas (corresponding to the first application scene superimposed on the second application scene) are arranged in the target area and the specified parameters of the at least two single TR antennas further include arrival delay and arrival angle, the location information of the target terminal in the target area is determined based on the location information of the at least two single TR antennas in the target area, the measured values ​​of the arrival delay and arrival angle in the measurement reports corresponding to the at least two single TR antennas, and the uplink time of arrival positioning method UTOA and angle of arrival positioning method AOA, or the location information of the target terminal in the target area is determined based on the location information of the at least two single TR antennas in the target area, the measured values ​​of the arrival delay and arrival angle in the measurement reports corresponding to the at least two single TR antennas, and the uplink time difference of arrival positioning method UTDOA and angle of arrival positioning method AOA.

[0095] As can be understood, when the first application scenario is superimposed on the second application scenario (i.e., the third application scenario described below), the target area in which the target terminal is located is first determined based on the method described above for the second application scenario, and then the specific location of the target terminal in the target area is determined based on the method described above for the first application scenario, thereby enabling the accurate location of the target terminal to be determined. For specific calculation methods, please refer to the above description of the corresponding application scenario and will not be further described here.

[0096] Optionally, in a second application scenario, before determining the location of the section in which the single TR antenna corresponding to the maximum value is located as the target section in which the target terminal is located, it may be determined whether there is an abnormality in the measured values ​​of received signal strength in the multiple measurement reports, and if it is determined that there is no abnormality in the measured values ​​of received signal strength in the multiple measurement reports, the location of the section in which the single TR antenna corresponding to the maximum value or maximum value is located is determined as the location in which the target terminal is located.

[0097] Here, a method for determining whether or not an abnormality exists in the measured value of the received signal strength in the measurement report is to determine whether the measured value of the received signal strength is clearly lower than a normal value (e.g., the rated minimum value), and if it is lower than the normal value, determine that an abnormality exists; otherwise, determine that no abnormality exists; alternatively, the determination may be made using the trend of change in the above-mentioned broken line, and if an abnormality exists in the trend of change in the broken line, for example, if an abnormal valley appears, determine that an abnormality exists; otherwise, determine that no abnormality exists.

[0098] 3) The third application scenario (LOS scenario + multiple compartments) In actual applications, the first application scene and the second application scene may occur simultaneously. That is, the target positioning scene includes a scene with multiple zones, and the multiple zones include at least one first zone that is not obstructed by obstacles. Specifically, as shown in FIG. 6, one actual application scene includes five zones, of which the second zone is a relatively large LOS scene (first zone). As shown in FIG. 7, one actual application scene includes two zones, both of which are relatively large LOS scenes (first zones). For such scenes, the positioning demand is modified as follows: First, determine which zone the target terminal is located in, and then determine whether the zone is an LOS scene. If the result is YES, determine the location of the target terminal in the zone.

[0099] In this scenario, a delay-based positioning method and a received signal strength-based positioning method may be simultaneously adopted, and the specified parameters may include arrival delay and received signal strength, and optionally, the specified parameters may include arrival angle.

[0100] In this scenario, the single TR antenna arrangement manner includes the following: the multiple single TR antennas include a first single TR antenna and a second single TR antenna, at least one of the first single TR antenna and one of the second single TR antennas are arranged in one first section, one of the second single TR antennas is arranged in one second section, the designated parameters measured by the first single TR antenna include at least one of an arrival delay and an arrival angle, the designated parameters measured by the second single TR antenna include a received signal strength, and the designated parameters measured by the second single TR antenna further include at least one of an arrival delay and an arrival angle, and the second section is a section other than the first section among the multiple sections.

[0101] As shown in Figure 6, one second single TR antenna is arranged in the central region of each of the second sections of Section 1, Section 3, Section 4 and Section 5, one first single TR antenna is arranged in each of the three corners of Section 2 (first section), and one second single TR antenna is arranged in the remaining corner. In actual application, in the application scenario shown in Figure 6, an 8TR 5G base station is selected as the network side equipment for positioning, and this 8TR 5G base station can be changed into a 5G base station with eight remotely installed single TR antennas, and the eight single TR antennas can be arranged as shown in Figure 6.

[0102] As shown in Figure 7, one first single TR antenna plane is arranged at each of the three corners of Section 1 (first section) and Section 2 (first section), and one second single TR antenna is arranged at the remaining corner. In actual application, in the application scenario shown in Figure 7, an 8TR 5G base station is selected as the network side device for positioning, and this 8TR 5G base station can be changed into a 5G base station with eight remotely installed single TR antennas, and the eight single TR antennas can be arranged as shown in Figure 7.

[0103] If the second single TR antenna also participates in the delay positioning, the second single TR antenna is not only used to measure the received signal strength, but also used to measure at least one of the arrival time and the arrival angle. In other words, the difference between the second single TR antenna and the first single TR antenna is that the second single TR antenna also measures the received signal strength.

[0104] In this scenario, for the first section, the placement principle of the single TR antenna follows the placement principle for the first application scenario described above, and for the second section, the placement principle of the single TR antenna follows the placement principle for the second application scenario described above.

[0105] In this scene, step 202 may include determining a target section in which the target terminal is located based on location information of the second single TR antenna in the first section and the second section and measurement values ​​of received signal strength in measurement reports correspondingly measured by the second single TR antenna in the first section and the second section; if the target section is the first section, determining location information of the target terminal in the target section based on location information of the multiple single TR antennas and measurement values ​​of at least one of arrival delay and arrival angle in the multiple measurement reports; and if the target section is a second section, determining the location of the second section as the location in which the target terminal is located.

[0106] Here, for the specific process of determining the target area in which the target terminal is located based on the location information of the second single TR antenna in the first area and the second area, and the measured values ​​of the received signal strength in the measurement reports correspondingly measured by the second single TR antenna in the first area and the second area, reference may be made to the description of the second application scenario above; and for the specific process of determining the location information of the target terminal in the target area based on the location information of the multiple single TR antennas and the measured values ​​of at least one of the arrival delay and the arrival angle in the multiple measurement reports, reference may be made to the description of the first application scenario above, and no further description will be given here.

[0107] As can be seen from the above, whether positioning is based on arrival delay or received signal strength, the signal feeder line between the remotely installed single TR antenna and the network side device itself causes positioning signal loss. For example, as can be seen from the description of how to position a terminal device in the first application scenario above, the probe signal received by the single TR antenna experiences a first propagation delay in the signal feeder line corresponding to the single TR antenna. As can be seen from the description of how to position a terminal device in the second application scenario above, the probe signal received by the single TR antenna experiences a path loss in the signal feeder line corresponding to the single TR antenna. These losses affect positioning accuracy and must be discarded.

[0108] In view of this, regardless of whether the lengths of the signal feeder lines connecting different single TR antennas among the multiple single TR antennas and the network side device main body are the same or different, the above step 202 may include: for any one single TR antenna among the multiple single TR antennas, determining the propagation delay or path loss in the signal feeder line corresponding to the single TR antenna of the probe signal received by the single TR antenna based on the length of the signal feeder line between the single TR antenna and the network side device main body; and determining the location information of the target terminal based on the measurement value of the specified parameter in the measurement report corresponding to the single TR antenna and the propagation delay or path loss in the signal feeder line corresponding to the single TR antenna.

[0109] Here, for the detailed process of determining the location information of the target terminal based on the measurement value of the specified parameter in the measurement report corresponding to the single TR antenna and the propagation delay or path loss in the signal feeder line corresponding to the single TR antenna, please refer to the relevant descriptions of the first application scenario and the second application scenario above, respectively, and will not be further described here.

[0110] The above describes a terminal device positioning method according to an embodiment of the present application. The method involves remotely installing multiple TR antennas included in a single network side device, such that the network side device is equipped with multiple remotely installed single TR antennas, and these remotely installed single TR antennas are arranged at different positions in a target positioning scene. The single network side device can obtain multiple measurement reports for the target terminal through measurements by the multiple remotely installed single TR antennas, and determine location information of the target terminal based on measurements of specified parameters in the multiple measurement reports. As can be seen, the terminal device positioning solution according to the embodiment of the present application does not require multiple network side devices to be arranged in a target positioning scene, and can achieve terminal device positioning with a single network side device, thereby reducing the number of network side devices required for terminal device positioning, reducing power consumption, facilitating power control, and saving the deployment costs of network side devices required for positioning.

[0111] As shown in FIG. 8, an embodiment of the present application further provides a network side device including a plurality of remotely installed single TR antennas, where the plurality of single TR antennas are connected to the network side device main body via signal feeder lines, and the plurality of single TR antennas are used to respectively measure a target terminal at different positions in a target positioning scene and obtain a plurality of measurement reports for the target terminal, where one measurement report is obtained correspondingly by one single TR antenna measurement, and the measurement report includes measurement values ​​of specified parameters for determining the position of the target terminal.

[0112] As can be seen, when the network side equipment is used to locate the terminal equipment, the number of network side equipment required for the terminal equipment positioning can be reduced, power consumption can be reduced, and the deployment cost of the network side equipment required for positioning can be saved.
