Description

Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a positioning measurement method and device. Background Art

[0002] Carrier phase positioning technology performs positioning by measuring the carrier phase change of the reference signal from the transmitter to the receiver. However, in carrier phase positioning technology, the terminal device and the reference station (positioning reference unit, PRU) must simultaneously measure the reference signal sent by the base station to eliminate some error terms that vary with time. Taking downlink positioning as an example, the location management function (location management function, LMF) network element on the network side can configure a measurement time window for the terminal device and PRU, and instruct the terminal device and PRU to measure the downlink reference signal resource set within the measurement time window. However, the terminal device and PRU may not be able to measure the reference signal sent by the base station at the same time, resulting in low accuracy of positioning measurement.

[0003] Therefore, how to improve the accuracy of positioning measurement is an urgent problem to be solved. Summary of the invention

[0004] The present application provides a positioning measurement method and device, which can improve the accuracy of positioning measurement.

[0005] In a first aspect, a positioning measurement method is provided, which can be executed by a target device, and the target device can be a terminal device or a positioning auxiliary device, or a component in the terminal device or the positioning auxiliary device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device, or a logic module or software that can implement all or part of the functions of the positioning auxiliary device. The method includes: the target device receives first indication information from the LMF, and the first indication information is used to indicate a measurement time window, and the positioning reference signal (PRS) resource in the measurement time window belongs to at least one frequency point, and the at least one frequency point includes a target frequency point; the target device performs a first positioning measurement on the PRS resource of the target frequency point in the measurement time window according to the first indication information.

[0006] The PRS resource may be understood as a PRS resource or a PRS resource set.

[0007] Based on the above scheme, LMF instructs the target device to perform the first positioning measurement on the PRS resources of the target frequency point within the measurement time window through the first indication information, thereby avoiding the target device from arbitrarily selecting a frequency point from multiple frequency points within the measurement time window for positioning measurement, thereby avoiding the target device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of the positioning measurement.

[0008] In combination with the first aspect, in some implementations of the first aspect, all PRS resources in the measurement time window belong to the target frequency point.

[0009] In the case where there are resource sets of multiple frequencies in the same measurement time window, the target device needs to measure and report the PRS resource sets of multiple frequencies separately when measuring and reporting, which has high processing complexity. In the embodiment of the present application, the PRS resources in the measurement time window all belong to one frequency point, which can reduce the processing complexity of the positioning measurement of the target device and improve the efficiency of the positioning measurement. In addition, the above scheme can be applied to terminal devices that only support measuring a maximum of one frequency point in a measurement time window, thereby improving the applicability of the positioning measurement method.

[0010] In combination with the first aspect, in certain implementations of the first aspect, the target device performs a first positioning measurement on the PRS resources of the target frequency point within the measurement time window based on the first indication information, including: the target device only performs the first positioning measurement on the PRS resources of the target frequency point within the measurement time window.

[0011] Based on the above scheme, LMF can instruct the target device to perform positioning measurement only on the PRS resources of the target frequency point within the measurement time window, avoiding the target device measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0012] In combination with the first aspect, in certain implementations of the first aspect, before the target device performs the first positioning measurement only on the PRS resources of the target frequency point within the measurement time window, the method also includes: the target device sends first capability information to the LMF, and the first capability information is used to indicate that the number of frequency points that the target device can measure within the measurement time window is one.

[0013] Based on the above scheme, when the target device only supports measuring one frequency point within the measurement time window, LMF can instruct the target device to perform positioning measurement only on the PRS resources of the target frequency point within the measurement time window. The above scheme implements positioning measurement of low-capability target devices and can be applied to terminal devices that only support measuring at most one frequency point within a measurement time window, thereby improving the applicability of the positioning measurement method.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the target device performs a first positioning measurement on the PRS resources of the target frequency point within the measurement time window based on the first indication information, including: the target device preferentially performs the first positioning measurement on the PRS resources of the target frequency point within the measurement time window.

[0015] Based on the above scheme, LMF can instruct the target device to prioritize positioning measurement of the PRS resources of the target frequency point within the measurement time window, avoiding the target device measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0016] In combination with the first aspect, in certain implementations of the first aspect, before the target device preferentially performs the first positioning measurement on the PRS resources of the target frequency point within the measurement time window, the method also includes: the target device sends second capability information to the LMF, and the second capability information is used to indicate that the target device can measure multiple frequency points within the measurement time window.

[0017] Based on the above solution, if the target device supports measuring multiple frequencies within the measurement time window, LMF can instruct the target device to prioritize the PRS resources of the target frequency within the measurement time window for positioning measurement. The above solution avoids the target device measuring different frequencies within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0018] In combination with the first aspect, in certain implementations of the first aspect, the PRS resources within the measurement time window belong to multiple frequency points, and the first indication information also carries a priority, which is used to indicate the order in which the first positioning measurement is performed on the multiple frequency points within the measurement time window.

[0019] Based on the above scheme, LMF instructs the target device to perform the first positioning measurement on the PRS resources of multiple frequency points within the measurement time window in a certain order through priority, thereby avoiding the target device from arbitrarily selecting a frequency point from the multiple frequency points within the measurement time window for positioning measurement, thereby avoiding the target device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0020] In combination with the first aspect, in some implementations of the first aspect, the PRS resources of the target frequency point belong to the same positioning frequency layer (positioning frequency layer, PFL).

[0021] In combination with the first aspect, in some implementations of the first aspect, the first indication information is carried in a positioning request or auxiliary data.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: the target device receives second indication information from the LMF, and the second indication information is used to instruct the target device to perform a second positioning measurement on multiple PRS resources; the target device preferentially performs the second positioning measurement on the PRS resource of the target frequency point among the multiple PRS resources based on the second indication information and the first indication information.

[0023] Based on the above scheme, the target device preferentially measures the PRS resources of the target frequency point, avoiding the target device from arbitrarily selecting a certain frequency point from multiple frequency points for positioning measurement, thereby avoiding the target device from measuring different frequency points, thereby improving the accuracy of positioning measurement. In addition, when the target device performs the second positioning measurement, it is not limited to measuring the PRS resources of the target frequency point within the measurement time window, so that the measurement result of the second positioning measurement finally determined is more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0024] In combination with the first aspect, in some implementations of the first aspect, the first indication information and the second indication information are carried in the same information.

[0025] In combination with the first aspect, in some implementations of the first aspect, the PRS resource of the target frequency point within the measurement time window is associated with information of a reference network device.

[0026] Based on the above scheme, the PRS resources of the target frequency point within the measurement time window are associated with the information of the reference network device, so that the target device can report the measurement results after differentiation based on the reference network device, avoiding reporting a large number of measurement results for a single PRS to the LMF, reducing communication overhead and reducing the processing burden on the LMF side.

[0027] In combination with the first aspect, in some implementations of the first aspect, the target device includes a terminal device to be positioned and measured and / or a positioning auxiliary device.

[0028] In a second aspect, a positioning measurement method is provided, which can be executed by an LMF, or by a component in the LMF (e.g., a processor, a chip, or a chip system, etc.), or by a logic module or software that can implement all or part of the LMF functions. The method includes: the LMF sends a first indication message to a target device, the first indication message is used to indicate a measurement time window, the PRS resources in the measurement time window belong to at least one frequency point, the at least one frequency point includes a target frequency point, and the first indication message is also used to indicate that the target device performs a first positioning measurement on the PRS resources of the target frequency point in the measurement time window.

[0029] Based on the above scheme, LMF instructs the target device to perform the first positioning measurement on the PRS resources of the target frequency point within the measurement time window through the first indication information, thereby avoiding the target device from arbitrarily selecting a frequency point from multiple frequency points within the measurement time window for positioning measurement, thereby avoiding the target device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of the positioning measurement.

[0030] In combination with the second aspect, in certain implementations of the second aspect, the method also includes: the LMF receives first capability information from the target device, the first capability information is used to indicate that the number of frequency points that the target device can measure within the measurement time window is one, and the first indication information is specifically used to instruct the target device to perform the first positioning measurement only on the PRS resources of the target frequency point within the measurement time window.

[0031] Based on the above scheme, when the target device only supports measuring one frequency point within the measurement time window, LMF can instruct the target device to perform positioning measurement only on the PRS resources of the target frequency point within the measurement time window. The above scheme implements positioning measurement of low-capability target devices and avoids the target device measuring different frequencies within the same measurement time window, thereby improving the accuracy of positioning measurement. In addition, the above scheme can be applied to terminal devices that only support measuring a maximum of one frequency point within a measurement time window, thereby improving the applicability of the positioning measurement method.

[0032] In combination with the second aspect, in certain implementations of the second aspect, the method also includes: the LMF receives second capability information from the target device, the second capability information is used to indicate that the target device can measure multiple frequency points within the measurement time window, and the first indication information is specifically used to indicate that the target device prioritizes the PRS resources of the target frequency point within the measurement time window to perform a first positioning measurement.

[0033] Based on the above solution, if the target device supports measuring multiple frequencies within the measurement time window, LMF can instruct the target device to prioritize the PRS resources of the target frequency within the measurement time window for positioning measurement. The above solution avoids the target device measuring different frequencies within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0034] In combination with the second aspect, in certain implementations of the second aspect, the method also includes: the LMF sends second indication information to the target device, the second indication information being used to instruct the target device to perform a second positioning measurement on multiple PRS resources, wherein the first indication information is also used to indicate that the second positioning measurement of the PRS resources of the target frequency point takes precedence over the second positioning measurement of the PRS resources of frequencies other than the target frequency point.

[0035] Based on the above scheme, the target device preferentially measures the PRS resources of the target frequency point, avoiding the target device from arbitrarily selecting a certain frequency point from multiple frequency points for positioning measurement, thereby avoiding the target device from measuring different frequency points, thereby improving the accuracy of positioning measurement. In addition, when the target device performs the second positioning measurement, it is not limited to measuring the PRS resources of the target frequency point within the measurement time window, so that the measurement result of the second positioning measurement finally determined is more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0036] In a third aspect, a positioning measurement method is provided, which can be executed by a network device or LMF, or by a component in the network device or LMF (e.g., a processor, a chip, or a chip system, etc.), or by a logic module or software that can implement all or part of the network device functions, or by a logic module or software that can implement all or part of the LMF functions. The method includes: the LMF sends a first message to the network device, the first message carries a measurement time window, and a sounding reference signal (SRS) resource within the measurement time window belongs to at least one frequency point, and the at least one frequency point includes a target frequency point; the network device performs a first positioning measurement on the SRS resource of the target frequency point within the measurement time window according to the first information.

[0037] The SRS resource may be understood as an SRS resource, an SRS resource set or a bandwidth part (BWP).

[0038] Based on the above scheme, LMF instructs the network device to perform the first positioning measurement on the SRS resources of the target frequency point within the measurement time window through the first information, thereby avoiding the network device from arbitrarily selecting a frequency point from multiple frequency points within the measurement time window for positioning measurement, thereby avoiding each network device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of the positioning measurement.

[0039] In combination with the third aspect, in certain implementations of the third aspect, all SRS resources within the measurement time window belong to the target frequency point.

[0040] In the case where there are resource sets of multiple frequencies in the same measurement time window, the network device needs to measure and report the SRS resource sets of multiple frequencies separately when measuring and reporting, which has high processing complexity. In the embodiment of the present application, the SRS resources in the measurement time window all belong to one frequency, which can reduce the processing complexity of the network device performing positioning measurement and improve the efficiency of positioning measurement.

[0041] In combination with the third aspect, in certain implementations of the third aspect, the network device performs a first positioning measurement on the SRS resources of the target frequency point within the measurement time window based on the first information, including: the network device only performs the first positioning measurement on the SRS resources of the target frequency point within the measurement time window.

[0042] Based on the above scheme, LMF can instruct the network device to perform positioning measurement only on the SRS resources of the target frequency point within the measurement time window, avoiding the network device measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0043] In combination with the third aspect, in certain implementations of the third aspect, the network device performs a first positioning measurement on the SRS resources of the target frequency point within the measurement time window based on the first information, including: the network device preferentially performs the first positioning measurement on the SRS resources of the target frequency point within the measurement time window.

[0044] Based on the above solution, LMF can instruct the network device to preferentially perform positioning measurement on the SRS resources of the target frequency point within the measurement time window. The above solution avoids the network device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0045] In combination with the third aspect, in certain implementations of the third aspect, the SRS resources within the measurement time window belong to multiple frequency points, and the first information also carries a priority, which is used to indicate the order in which the first positioning measurement is performed on the multiple frequency points within the measurement time window.

[0046] Based on the above scheme, LMF instructs the network device to perform the first positioning measurement on the SRS resources of multiple frequency points within the measurement time window in a certain order through priority, avoiding the network device from arbitrarily selecting a frequency point for positioning measurement from multiple frequency points within the measurement time window, thereby avoiding the network device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0047] In combination with the third aspect, in certain implementations of the third aspect, the SRS resources of the target frequency point belong to the same component carrier (CC).

[0048] In combination with the third aspect, in some implementations of the third aspect, the first information is carried in a measurement request.

The CU implements some functions of the gNB, and the DU implements some functions of the gNB, for example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers.

Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also realize powerful functions through software support, data interaction, and cloud interaction.In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0099] Figure 1 It is a schematic diagram of a communication system 100 applied in an embodiment of the present application.

[0100] like Figure 1 As shown, the communication system 100 includes a terminal device ( Figure 1 UE) and the radio access network ( Figure 1 In the figure, it is represented as gNB and next generation evolved node B (ng-eNB). ng-eNB represents an LTE base station connected to the 5G core network, and gNB represents a 5G base station connected to the 5G core network. It should be understood that the above Figure 1 The communication system 100 shown may include one or more base stations (including ng-eNB or gNB), and may also include one or more terminal devices, for example, one or more terminal device groups, etc. Figure 1 It is not drawn in the figure, and this application does not limit this. It should be understood that the ng-eNB and the gNB, or between two ng-eNBs, or between two gNBs communicate through the Xn interface, and the Xn interface can also be called the XnAP interface. The gNB or Ng-eNB communicates with the UE through the air interface (the radio interface between UTRAN and UE, Uu interface), and the UEs communicate through the proximity-based services communication 5 (proximity-based services communication 5, PC5) interface.

[0101] Figure 2 A schematic diagram of another communication system 200 applied in an embodiment of the present application.

[0102] like Figure 2 As shown, the communication system 200 includes a terminal device ( Figure 2 UE), wireless access network ( Figure 2 In the figure, it is represented as the next generation radio access network (NG-RAN) and the core network.

[0103] The radio access network includes one or more ng-eNBs and gNBs. The radio access network is connected to the core network via the NG-C interface. The radio access network is able to send and receive PRS and obtain related measurement information.

[0104] The core network includes access and mobility management function (AMF) and location management function (LMF).

[0105] LMF is responsible for supporting different types of location services related to UE, including positioning of UE and transmission of auxiliary data to UE. The control plane and user plane of LMF are the enhanced-serving mobile location center (E-SMLC) and the secure user plane locator platform (SLP), respectively. LMF may interact with RAN, such as ng-eNB or gNB, and UE through signals. For example, LMF and ng-eNB or gNB exchange information through new radio positioning protocol annex (NRPPa) messages, such as obtaining configuration information of PRS and SRS, cell timing, cell location information, etc. For another example, LMF and UE transmit UE capability information, auxiliary information, measurement information, etc. through LTE positioning protocol (LPP) messages.

[0106] The AMF can receive location service requests related to the UE from the location service (LCS) entity or other network elements of the 5G core network (5G core, 5GC), or the AMF itself can also start some location services on behalf of a specific UE and forward the location service request to the LMF.

[0107] The terminal device is connected to the radio access network via the ng-eNB through the LTE-Uu interface. The terminal device can also be connected to the radio access network via the gNB through the NR-Uu interface.

[0108] It should be understood that the communication system 200 may include one or more base stations (including ng-eNB or gNB). It should also be understood that the communication system 200 may include one or more terminal devices, for example, one or more terminal device groups.

[0109] It should also be understood that a gNB can send data or control signaling to one or more terminal devices. Multiple gNBs can also send data or control signaling to a terminal device at the same time. Figure 2The ng-eNB in ​​the example can also be TRP or TP, and the nNB can also be TRP or transmission measurement function (TMF), etc.

[0110] The embodiments of the present application can also be applied to a communication architecture based on a PC5 interface. For example, the UE may include a location management component (LMC). The LMC is a component / application deployed on the UE with partial LMF functions, which is used to support positioning services on the PC5 port.

[0111] Positioning is an important function in mobile communication systems, requiring the system to provide users' location information in real time. 5G communication systems require high-precision positioning, requiring outdoor positioning errors to be less than 10 meters and indoor positioning errors to be less than 1 meter.

[0112] Positioning technology may include uplink positioning, downlink positioning and uplink and downlink positioning. In uplink positioning, the base station measures the SRS signal sent by the UE, and in downlink positioning, the UE measures the PRS signal sent by the base station. In uplink and downlink positioning, the UE is required to measure both the PRS signal sent by the base station and the SRS signal sent by the UE.

[0113] The relevant technical solutions support multiple positioning technologies such as downlink-time difference of arrival (DL-TDOA) positioning technology, downlink-angle of departure (DL-AOD) positioning technology, UL-TDOA positioning technology, uplink-angle of arrival (UL-AOA) positioning technology, and multi-round trip time (multi-RTT) positioning technology. Among them, DL-TDOA, UL-TDOA and multi-RTT are positioning technologies based on arrival time, that is, the receiving end is required to measure the arrival time of the signal sent by the sending end, and then convert it into the distance information between the two, and finally obtain the position of the target to be located. DL-AOD and UL-AOA are positioning technologies based on angles, that is, the receiving end measures the arrival angle of the reference signal sent by the sending end, and then infers the position of the receiving end based on the angle information between the receiving end and multiple senders with known positions.

[0114] Figure 3 is a schematic flow chart of a positioning measurement method 300. Figure 3 , taking UL-TDOA as an example to introduce the positioning process.

[0115] UL-TDOA requires the base station side (i.e., the network equipment side) to measure the uplink reference signal, such as measuring the arrival time of the SRS sent by the UE to be located. Figure 3 ,The measurement process generally goes through the following process.

[0116] LMF requests SRS configuration information from the serving base station, and the serving base station feeds back the SRS configuration information to LMF; the serving base station sends the SRS configuration information to the UE to be located, and indicates the SRS configuration information to the neighboring base stations; LMF sends measurement requests to the serving base station and the neighboring base station, and after receiving the measurement request from LMF, the serving base station and the neighboring base station respectively receive the SRS sent by the UE to be located, and respectively measure the arrival time of the SRS; the serving base station and the neighboring base station respectively report the measurement information to LMF, and LMF uses the arrival time in the received measurement information to estimate the position and determine the position information of the UE to be located.

[0117] Among them, the serving base station is a base station located in the cell where the UE to be located is located, and the serving base station can provide communication connection services for the UE to be located. There are at least two neighboring base stations, and the neighboring base stations can be the base station of the cell where the UE to be located is located, or the base stations of other cells, or part of the base stations of the cell where the UE to be located is located, and part of the base stations of other cells. LMF can calculate the position of the UE to be located based on the measurement information of the serving base station and the measurement information of the neighboring base stations. The positioning principle and calculation process are introduced below.

[0118] The positioning principle of UL-TDOA is to locate the source of the radio signal by measuring the time difference between the SRS arriving at different base stations. Specifically, LMF calculates the time difference between the SRS arriving at two base stations, obtains the distance difference based on the time difference, and thus obtains a hyperbola; LMF can obtain two or more hyperbolas through the time difference measured by three or more base stations, and then, LMF realizes the positioning of the transmitting source based on the intersection of the two or more hyperbolas.

[0119] Figure 4 Schematic diagram of UL-TDOA positioning technology. Figure 4 The UE to be located in can send SRS, Figure 4 The base stations 1, 2 and 3 in the figure correspond to the serving base station and the neighboring base station for measuring SRS in the above UL-TDOA positioning technology. Among them, one of the base stations 1, 2 and 3 is the serving base station of the terminal device, and the other two base stations are the neighboring base stations of the terminal device. Figure 4 , the UE to be located sends an SRS, and base station 1, base station 2 and base station 3 respectively measure the SRS sent by the UE to be located.

[0120] Assume that the locations of the three base stations are known, and define the coordinates of the ith base station as (x i ,y i ), i = 1, 2, 3; the coordinates of the UE to be located are (x UE ,y UE ), and base station 1 is used as the reference base station, and the arrival time of the SRS measured by the other two base stations is t i , then the arrival time difference between base station 2 and base station 3 and base station 1 is Δt i1 According to the definition of a hyperbola (the distance from two fixed points is a constant), the UE to be located is located on the hyperbola with base stations 2 and 3 as foci, and the following set of equations can be listed:

[0121]

[0122]

[0123] In the above two equations, c is the speed of light, because there are only two unknowns (x UE ,y UE ), the location information of the UE to be located can be obtained by solving the above two equations. In fact, due to the existence of measurement errors, the above equations generally have no analytical solutions. In engineering, optimization algorithms such as the least squares algorithm or the particle swarm filter algorithm are used to estimate the optimal solutions of the above two equations.

[0124] To describe it from another perspective, the arrival time difference between the SRS sent by the UE to be located and the arrival time of base station 1 and base station 2 is Δt 21 The arrival time difference between the SRS sent by the UE to be located and the base station 1 and base station 3 is Δt 31 . The arrival time difference Δt 21 Multiply by the speed of light to get the distance difference L1, and convert the arrival time difference Δt 21 Multiply by the speed of light to get the distance difference L2. LMF can be obtained based on the functional relationship between the position of base station 1, the position of base station 2 and the distance difference L1. Figure 4 The hyperbola MN shown in FIG. 1 is obtained according to the functional relationship between the position of base station 1, the position of base station 3 and the distance difference L2. Figure 4 The hyperbola RS shown in . Further, the LMF can realize the positioning of the UE to be positioned according to the intersection point of the hyperbola MN and the hyperbola RS.

[0125] It should be noted that in Figure 4 In the present invention, three base stations are used to realize the positioning of the terminal device, but the present application does not limit this. In actual applications, more than three base stations can also be used to realize the positioning of the terminal device.

[0126] The relevant technical solution can use carrier phase positioning technology for positioning measurement. Carrier phase positioning technology measures the distance with integer ambiguity by measuring the carrier phase change of the reference signal from the transmitter to the receiver. Taking the 3GHz RF signal as an example, the corresponding carrier wavelength is 0.1 meter; therefore, when the carrier phase integer ambiguity can be correctly solved, the carrier phase ranging accuracy can theoretically reach the centimeter to millimeter level, thereby obtaining a high-precision positioning result.

[0127] Figure 5 This is a schematic diagram of carrier phase ranging. Figure 5 , d is the distance between the receiving end and the transmitting end, is the carrier phase measurement value, N is the integer ambiguity value, indicating that the reference signal has passed N carrier cycles in space. λ is the carrier wavelength, and the distance d is related to the carrier phase. The following equation is satisfied.

[0128]

[0129] The positioning assistance device may be referred to as an anchor node, which may send and / or measure a PRS or SRS, thereby assisting the positioning measurement of the UE to be positioned. The positioning assistance device may be an anchor terminal device, a positioning reference unit (PRU), etc.

[0130] By using a positioning auxiliary device with a known position to measure PRS or SRS, the influence of non-ideal factors can be eliminated according to the double-difference carrier phase method to improve positioning accuracy. For example, non-ideal factors include time synchronization error, random initial phase error, clock drift frequency deviation, and industrial parameter error of network equipment. The description of carrier phase positioning in R18 also supports the use of PRU to assist in the measurement of carrier phase and improve the accuracy of carrier phase positioning. Figure 6 , some embodiments of the double-difference carrier phase method are introduced by taking downlink positioning as an example.

[0131] Figure 6 It is a schematic diagram of positioning measurement using the double-difference carrier phase method.

[0132] See also Figure 6 , assuming that the UE to be located ( Figure 4 Indicated by circles), PRU( Figure 4 The UE to be located measures the PRS ( Figure 4 Indicated by a solid arrow in the figure), the PRU measures the PRS sent by base station i ( Figure 4The phase measurement value of the UE to be located relative to the base station i can be determined by the following formula.

[0133]

[0134] in, is the phase measurement value of the UE to be located relative to base station i; is the transmission delay between the UE to be located and base station i; is the time synchronization error between base station i and UE; φ t is the random initial phase error of the UE to be located; φ (i) is the random initial phase error of base station i, is the integer ambiguity between UE and base station i.

[0135] By making a difference between different base stations, the phase difference of arrival (PDOA) of the UE to be located is obtained. The specific formula is as follows.

[0136]

[0137] in, is the phase measurement value of the UE to be located relative to base station j (j is 1, 2 or 3, j is different from i) The phase measurement value of the UE to be located relative to base station i The difference between is the transmission delay between the UE to be located and base station j The transmission delay between the UE to be located and the base station i The difference between (ij) is the time synchronization error between base station j and UE The time synchronization error between base station j and UE The difference between (ij) is the random initial phase error φ of base station j (j) and is the random initial phase error φ of base station i (i) The difference between is the integer ambiguity between UE and base station j and is the integer ambiguity between UE and base station i The difference between .

[0138] The above formula can eliminate the random initial phase φ of the UE to be located. t Similarly, the PDOA with respect to PRU can be obtained by the following formula.

[0139]

[0140] The parameters in the above formula can be found in the calculation The description of the formula is that the subscript t is replaced by the subscript p, and the meaning of each parameter in the above formula is not repeated. The double difference PDOA can be obtained by subtracting the PDOA of the UE to be located from the PDOA of the PRU. The specific formula is as follows.

[0141]

[0142] in, yes and The difference between for and The difference between for and The above formula can eliminate the random initial phase error φ on the base station side. (ij) And the time synchronization error Δ (ij) , thus determining according to The difference between the first distance difference and the second distance difference can be determined. The first distance difference is the distance difference between the distance from base station i to the UE to be located and the distance from base station i to the PRU, and the second distance difference is the distance between the distance from base station j to the UE to be located and the distance from base station j to the PRU. In other words, by introducing more base stations or PRUs, multiple double-difference PDOAs can be obtained, and combined with the location information of the PRU and the location information of the base station, the location estimation result of the UE to be located can be solved.

[0143] For example, the UE to be located can be initially roughly located by using a positioning technology based on measuring arrival time or arrival angle to determine the PRU that is close to the UE. Then, the double-difference carrier phase positioning technology can be used to accurately measure the position of the UE.

[0144] The random initial phase φ on the base station side (i) And the time synchronization error Δ (ij) is an error term that varies with time. Therefore, in the above double-difference carrier phase positioning, the UE to be positioned and the PRU must simultaneously measure the PRS sent by the base station, so that the random initial phase error φ on the base station side can be eliminated by the above differential method. (i) And the time synchronization error Δ (ij) .

[0145] For example, LMF can configure a measurement time window for the UE or PRU to be located, and instruct the UE or PRU to be located to perform positioning measurements within the measurement time window. The duration of the measurement time window can be 1, 2, 4, 6, 8, 12 or 16 time slots, and the configured measurement time window can be 1 or 2. There can be one or more frequency resource sets in a measurement time window, where the resource set can be a PRS resource or an SRS resource, which is not limited in this application.

[0146] For PRS resources, belonging to a frequency point may mean that these PRS resources (or PRS resource set) belong to the same PFL; for SRS resources, belonging to the same frequency point may mean that these SRS resources (or SRS resource set, BWP) belong to the same CC.

[0147] Figure 7 is a schematic diagram of configuring the measurement time window. Figure 7 , Figure 7 The upper part of represents the time domain resources for transmission by the UE to be located, wherein "D" represents the downlink transmission time slot, "U" represents the uplink transmission time slot, and "S" represents the flexible transmission time slot.

[0148] Taking downlink positioning as an example, the LMF network element configures a measurement time window for the UE to be positioned and the PRU, and instructs the UE to be positioned and the PRU to measure the PRS resources within the measurement time window. When there are resource sets of multiple frequencies within the measurement time window configured by the LMF for the UE to be positioned or the PRU, the UE to be positioned and the PRU may not be able to measure the PRS sent by the base station at a certain frequency at the same time.

[0149] Assume that the LMF configures a measurement time window for the UE and PRU, which is recorded as measurement time window 1. The measurement time window 1 is periodically distributed on the time domain resources of the UE and PRU, for example Figure 7 As shown. The PRS resources configured in measurement time window 1 belong to two frequency points, namely frequency point 1 and frequency point 2. In other words, there are PRS resources of frequency point 1 and frequency point 2 in measurement time window 1. The UE to be located can choose to measure the PRS resources of frequency point 1 or frequency point 2 in measurement time window 1, and the PRU can also choose to measure the PRS resources of frequency point 1 or frequency point 2 in measurement time window 1.

[0150] In this case, the UE to be located and the PRU may not be able to measure the PRS sent by the base station at a certain frequency at the same time. For example, the UE to be located measures the PRS resources of frequency 1 in the first measurement time window 1, and measures the PRS resources of frequency 2 in the measurement time window 1 of the next cycle. The PRU measures the PRS resources of frequency 2 in the first measurement time window 1, and measures the PRS resources of frequency 1 in the measurement time window 1 of the next cycle. In this way, the measurement time of the PRS resources of frequency 1 and the PRU of frequency 2 for the UE to be located and the PRU are different, which results in the UE to be located and the PRU being unable to eliminate the irrational factors that change with time through the double-difference carrier phase method, affecting the accuracy of the positioning measurement.

[0151] Therefore, how to improve the accuracy of positioning measurement is an urgent problem to be solved.

[0152] Figure 8 800 is a schematic flow chart of a positioning measurement method 800 provided in an embodiment of the present application. The method 800 can improve the accuracy of downlink positioning measurement. Figure 8 The various actions of method 800 are introduced.

[0153] S810, the target device receives first indication information from the LMF, the first indication information is used to indicate a measurement time window, the PRS resources in the measurement time window belong to at least one frequency point, and the at least one frequency point includes a target frequency point. Correspondingly, the LMF sends the first indication information to the target device, and the first indication information is also used to instruct the target device to perform a first positioning measurement on the PRS resources of the target frequency point in the measurement time window.

[0154] In some embodiments, the target device includes a terminal device and / or a positioning auxiliary device to be positioned and measured. That is, the LMF can send the first indication information to the terminal device, can also send the first indication information to the positioning auxiliary device, and can also send the first indication information to the terminal device and the positioning auxiliary device. The positioning auxiliary device can be one or more. The positioning auxiliary device can be a PRU or other devices.

[0155] The first indication information may be carried in any message, for example, in assistant data. The assistant data may also carry the configuration of some or all of the PRS resources, and may also carry the coordinates of the network device (for example, gNB coordinates or TRP coordinates). For example, the first indication information may be carried in a positioning request, which may be used to request the target device to measure the PRS resources.

[0156] The first indication information may be used to indicate the measurement time window, but the present application does not limit this. For example, the first indication information may also carry the indication measurement time window, or the first indication information may include the measurement time window.

[0157] It is understandable that each of the multiple time windows may be configured with PRS resources of one frequency point or multiple frequencies, or may not be configured with PRS resources. Among them, a time window configured with at least one frequency point can be selected as a measurement time window.

[0158] In some embodiments, the PRS resources in the measurement time window all belong to the target frequency point. In other words, the PRS resources in the measurement time window belong to only one frequency point. In other words, there is only one PRS resource at one frequency point in the measurement time window.

[0159] PRS resources belonging to the same frequency point may mean that these PRS resources belong to the same PFL. For example, the PRS resources of the target frequency point belong to the same PFL. PRS resources belonging to the same frequency point may also mean that these PRS resources have the same absolute radio frequency channel number (ARFCN). For example, the PRS resources of the target frequency point have the same ARFCN. PRS resources belonging to the same frequency point may also mean that these PRS resources have the same frequency point parameters (point A). For example, the PRS resources of the target frequency point have the same point A.

[0160] In the case where there are resource sets of multiple frequencies in the same measurement time window, the target device needs to measure and report the PRS resource sets of multiple frequencies separately when measuring and reporting, which has high processing complexity. In the embodiment of the present application, the PRS resources in the measurement time window all belong to one frequency point, which can reduce the processing complexity of the positioning measurement of the target device and improve the efficiency of the positioning measurement. In addition, the above scheme can be applied to terminal devices that only support measuring a maximum of one frequency point in a measurement time window, thereby improving the applicability of the positioning measurement method.

[0161] In some other embodiments, the PRS resources in the measurement time window belong to multiple frequency points. The first indication information may be used to indicate one frequency point among the multiple frequency points as a target frequency point.

[0162] The PRS resource may refer to a PRS resource or a PRS resource set. The PRS resource within the measurement time window may be one or more PRS resources or one or more PRS resource sets.

[0163] The first positioning measurement may be a positioning measurement of a carrier phase, or a positioning measurement of time. For example, the measurement result of the positioning measurement of the carrier phase may include the carrier phase (reference signal carrier phase, RSCP) of a reference signal resource set and / or the carrier phase difference (reference signal carrier phase difference, RSCPD) of a reference signal resource set, etc. For another example, the measurement result of the positioning measurement of time may include at least one of the following: relative time of arrival (relative time of arrival, RTOA), reference signal arrival time difference (reference signal time difference, RSTD), the Rx-Tx time difference of the terminal device, the Rx-Tx time difference of the base station, etc.

[0164] S820: The target device performs a first positioning measurement on the PRS resource of the target frequency point within the measurement time window according to the first indication information.

[0165] Based on the above scheme, LMF instructs the target device to perform the first positioning measurement on the PRS resources of the target frequency point within the measurement time window through the first indication information, thereby avoiding the target device from arbitrarily selecting a frequency point from multiple frequency points within the measurement time window for positioning measurement, thereby avoiding the target device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of the positioning measurement.

[0166] In some embodiments, S820 includes: the target device only performs the first positioning measurement on the PRS resource of the target frequency point within the measurement time window.

[0167] As an example, the LMF may choose to configure a time window of only one frequency point as the measurement time window. In this way, the PRS resources in the measurement time window indicated by the first indication information sent by the LMF in S810 all belong to one frequency point.

[0168] As another example, the LMF may select a time window configured with multiple frequency points as a measurement time window, and indicate one of the multiple frequency points within the measurement time window as a target frequency point.

[0169] Based on the above scheme, LMF can instruct the target device to perform positioning measurement only on the PRS resources of the target frequency point within the measurement time window, avoiding the target device measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0170] In some embodiments, before the target device performs the first positioning measurement only on the PRS resource of the target frequency point within the measurement time window, the method 800 further includes: the target device sends first capability information to the LMF, the first capability information is used to indicate that the number of frequency points that the target device can measure within the measurement time window is one. Correspondingly, the LMF receives the first capability information from the target device, the first indication information is specifically used to indicate that the target device performs the first positioning measurement only on the PRS resource of the target frequency point within the measurement time window.

[0171] It is understandable that the target device can report the PRS resources that can support the measurement of a maximum of several frequency points in a measurement time window, and help the LMF configure the number of frequency points in the measurement time window by reporting capability (capability transfer). For the purpose of distinction, when the number of frequency points that the target device can measure in the measurement time window is one, the capability information reported by the target device is called the first capability information.

[0172] Based on the above scheme, when the target device only supports measuring one frequency point within the measurement time window, LMF can instruct the target device to perform positioning measurement only on the PRS resources of the target frequency point within the measurement time window. The above scheme implements positioning measurement of target devices with low capabilities (such as reduced capability (RedCap)), and can be applicable to terminal devices that only support measuring at most one frequency point within a measurement time window, thereby improving the applicability of the positioning measurement method.

[0173] In some embodiments, S820 includes: the target device preferentially performs the first positioning measurement on the PRS resource of the target frequency point within the measurement time window.

[0174] As an example, LMF can indicate one of the multiple frequency points in the measurement time window as the target frequency point, and instruct the target device to preferentially measure the PRS resource of the target frequency point in the measurement time window. For example, there are frequency points 1 and 2 in measurement time window 1, and it is assumed that the target frequency point is 1. In this way, the target device can preferentially measure frequency point 1 in the first measurement time window, and measure frequency point 2 in the measurement time window 1 of the next cycle, thereby avoiding the target device measuring different frequency points in the same measurement time window.

[0175] Based on the above scheme, LMF can instruct the target device to prioritize positioning measurement of the PRS resources of the target frequency point within the measurement time window, avoiding the target device measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0176] In some embodiments, before the target device preferentially performs the first positioning measurement on the PRS resource of the target frequency point within the measurement time window, the method 800 further includes: the target device sends second capability information to the LMF, the second capability information is used to indicate that the number of frequency points that the target device can measure within the measurement time window is multiple. Correspondingly, the LMF receives the second capability information from the target device, and the first indication information is specifically used to indicate that the target device preferentially performs the first positioning measurement on the PRS resource of the target frequency point within the measurement time window.

[0177] It is understandable that the target device can report the PRS resources that can support the measurement of a maximum of several frequency points in a measurement time window, and help the LMF configure the number of frequency points in the measurement time window by reporting capabilities. For the purpose of distinction, when the number of frequency points that the target device can measure in the measurement time window is multiple, the capability information reported by the target device is called the second capability information.

[0178] Based on the above solution, if the target device supports measuring multiple frequencies within the measurement time window, LMF can instruct the target device to prioritize the PRS resources of the target frequency within the measurement time window for positioning measurement. The above solution avoids the target device measuring different frequencies within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0179] In some embodiments, the PRS resources within the measurement time window belong to multiple frequency points, and the first indication information also carries a priority, where the priority is used to indicate the order in which the first positioning measurement is performed on the multiple frequency points within the measurement time window.

[0180] The PRS resources in the measurement time window belong to multiple frequency points, that is, the PRS resources in the measurement time window indicated by the first indication information sent by the LMF can be resources of different frequency points. In other words, there can be cross-frequency resources in the measurement time window, and these resources belong to different PFLs or different ARFCNs.

[0181] The first indication information also carries the priority, which can be understood as the first indication information also indicating the priority, or can also be understood as the first indication information also including the priority.

[0182] Priority can be understood as the frequency priority of different frequencies within the measurement time window, and priority is the order of PRS resources of different frequencies within the measurement time window for positioning measurement. The target device can measure and report multiple frequency points within the measurement time window according to the order of priority. For example, there are four frequency points {1, 2, 3, 4}, two measurement time windows {1, 2}, measurement time window 1 contains PRS resources of frequency points {1, 3}, and measurement time window 2 contains PRS resources of frequency points {2, 4}. By indicating that the priority of the frequency point is {1, 2, 3, 4}, the target device can first measure the PRS resources of frequency point 1 within the measurement time window 1, and then measure the PRS resources of frequency point 3. In the case where the target device includes a UE to be located and a positioning auxiliary device, the UE to be located and the positioning auxiliary device can measure the PRS resources of frequency points 1 and frequency point 3 simultaneously. Similarly, for measurement time window 2, the target device can first measure the PRS resources of frequency 2, and then measure the PRS resources of frequency 4. When the target device includes the UE to be located and the positioning auxiliary device, the above scheme realizes the simultaneous measurement of the PRS resources of frequency 2 and frequency 4 by the UE to be located and the positioning auxiliary device.

[0183] It should be noted that the present application does not limit the priority to indicate the order in which all frequency points in the measurement time window perform the first positioning measurement. For example, the priority may indicate the order in which some frequency points in the measurement time window perform the first positioning measurement. For frequency points whose priorities do not indicate an order, the target device may perform positioning measurements according to the existing scheme, or may not perform positioning measurements. In other words, the target device may first measure the PRS resources of the frequency points indicated in the priority in the order of priority, and then measure the PRS resources of the frequency points not indicated in the priority in a random order. Alternatively, the target device may only measure the PRS resources of the frequency points indicated in the priority in the order of priority, and not measure the PRS resources of the frequency points not indicated in the priority.

[0184] Based on the above scheme, LMF instructs the target device to perform the first positioning measurement on the PRS resources of multiple frequency points within the measurement time window in a certain order through priority, thereby avoiding the target device from arbitrarily selecting a frequency point from the multiple frequency points within the measurement time window for positioning measurement, thereby avoiding the target device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0185] In some embodiments, the method 800 further includes: the target device receives second indication information from the LMF, the second indication information being used to instruct the target device to perform a second positioning measurement on a plurality of PRS resources; the target device preferentially performs the second positioning measurement on the PRS resource of the target frequency point among the plurality of PRS resources according to the second indication information and the first indication information. Correspondingly, the LMF sends the second indication information to the target device, the first indication information being further used to indicate that the second positioning measurement on the PRS resource of the target frequency point takes precedence over the second positioning measurement on the PRS resource of the frequency point other than the target frequency point.

[0186] The second indication information may be the same as the first indication information. In other words, the target device may be instructed to perform both the first positioning measurement and the second positioning measurement through one indication information. In this way, the second indication information may also be referred to as the first indication information. It may also be understood that the second indication information and the first indication information are sent simultaneously.

[0187] Exemplarily, the first indication information and the second indication information are carried in the same information. It can also be understood that the first indication information and the second indication information are included in the same information. Exemplarily, the first indication information and the second indication information can be carried in the auxiliary data or the positioning request, or can be carried in other messages.

[0188] The second positioning measurement is similar to the first positioning measurement, except that the second positioning measurement is a measurement of the PRS resources, not limited to the PRS resources within the measurement time window. In other words, the second positioning measurement can measure both the PRS resources within the measurement time window and the PRS resources outside the measurement time window. It should be understood that the number of PRS resources on the time-frequency resources is usually greater than the number of PRS resources configured in the measurement time window. Therefore, the PRS resources measured by the target device on the time-frequency resources will be greater than the PRS resources only measured in the time window, so that the measurement result of the final determined time will be more accurate, thereby making the positioning of the terminal device more accurate. Alternatively, since the target device can measure both the PRS resources within the time window and the PRS resources outside the time window, the measured PRS resources will be more than the PRS resources only measured in the measurement time window, which will also make the final determined measurement result more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0189] Accordingly, the second positioning measurement is performed preferentially on the PRS resources of the target frequency among the multiple PRS resources, and is not limited to the PRS resources of the target frequency within the measurement time window. In other words, the second positioning measurement can measure the PRS resources of the target frequency within the measurement time window, and can also measure the PRS resources of the target frequency outside the measurement time window.

[0190] Based on the above scheme, the target device preferentially measures the PRS resources of the target frequency point, avoiding the target device from arbitrarily selecting a certain frequency point from multiple frequency points for positioning measurement, thereby avoiding the target device from measuring different frequency points, thereby improving the accuracy of positioning measurement. In addition, when the target device performs the second positioning measurement, it is not limited to measuring the PRS resources of the target frequency point within the measurement time window, so that the measurement result of the second positioning measurement finally determined is more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0191] In some embodiments, the PRS resource of the target frequency point within the measurement time window is associated with information of a reference network device.

[0192] For example, assume that there are three PRS resources in the target frequency point, namely PRS resource 1, PRS resource 2 and PRS resource 3. The target device receives PRS from base station 1, base station 2 and base station 3 respectively according to PRS resource 1, PRS resource 2 and PRS resource 3, thereby realizing the positioning measurement of PRS resource 1, PRS resource 2 and PRS resource 3. Among them, base station 1 is a reference network device, and PRS resource 1, PRS resource 2 and PRS resource 3 are all associated with the information of base station 1. In this way, the target device can differentiate the results measured by PRS resource 1 and PRS resource 2, differentiate the results measured by PRS resource 1 and PRS resource 3, and report the differentiated measurement results to LMF.

[0193] If the PRS resource of the target frequency point within the measurement time window is not associated with the information of the reference network device, the target device cannot determine the measurement result after differential based on the reference network device, and cannot determine the information of the reference network device. The differential measurement result may not be based on the same reference network device, so only the measurement result of a single PRS resource can be reported. In this case, the target device needs to report more measurement results, and the LMF needs to receive and process more measurement results, which increases the communication overhead and the processing burden on the LMF side.

[0194] Based on the above scheme, the PRS resources of the target frequency point within the measurement time window are associated with the information of the reference network device, so that the target device can report the measurement results after differentiation based on the reference network device, avoiding reporting a large number of measurement results for a single PRS to the LMF, reducing communication overhead and reducing the processing burden on the LMF side.

[0195] Fig. 9 It is a schematic flow chart of another positioning measurement method 800 provided in an embodiment of the present application. Fig. 9 The illustrated method 800 includes the following steps.

[0196] Step 1: LMF obtains the capability of the target device through the LPP capability transfer process. This step can be regarded as capability reporting. The reported capability information may include the PRS resources or resource sets of the maximum number of frequency points that the target device supports to measure within a measurement time window.

[0197] Step 2: LMF makes an information request to the serving base station and the neighboring base station (e.g., gNB or TRP) to request gNB / TRP information. The requested information includes the cell information of the serving base station and the neighboring base station, the coordinates of the serving base station and the neighboring base station, the IDs of the serving base station and the neighboring base station, the configuration of PRS resources, etc.

[0198] Step 3. The serving base station and the neighboring base station (e.g., gNB or TRP) send an information response to the LMF in response to the requested information. The response information includes the cell information of the serving base station and the neighboring base station, the coordinates of the serving base station and the neighboring base station, the IDs of the serving base station and the neighboring base station, the configuration of PRS resources, etc.

[0199] Step 4: LMF transmits or provides auxiliary data to the target device, where the auxiliary data includes PRS resource configuration. The auxiliary data may also include the coordinates of the serving base station and neighboring base stations. The auxiliary data may also be referred to as auxiliary information.

[0200] Step 5: LMF requests location information from the target device and requests the target device to measure PRS. The location information request may include first indication information, which is used to indicate the measurement time window and the target frequency point within the measurement time window. If there are multiple frequency points within the measurement time window, the priority of the frequency points may also be indicated.

[0201] It should be noted that the first indication information may also be sent in step 4, that is, carried in the auxiliary data.

[0202] Step 6: The target device measures the PRS and obtains a measurement result. For example, the measurement result may include RSTD and RSCPD, but the present application is not limited thereto. For example, the measurement result may also be other time measurement quantities, or other carrier phase measurement quantities.

[0203] Step 7: The target device reports the measurement results to LMF.

[0204] Combined with the above Figure 8 and Fig. 9 Some embodiments of downlink positioning have been introduced, and some embodiments of uplink positioning are described below.

[0205] Fig.101 is a schematic flow chart of another positioning measurement method 1000 provided in an embodiment of the present application. The method 1000 can improve the accuracy of downlink positioning measurement. Fig.10 The various actions of method 1000 are introduced.

[0206] S1010, LMF sends first information to the network device, where the first information carries a measurement time window, and SRS resources within the measurement time window belong to at least one frequency point, and the at least one frequency point includes a target frequency point.

[0207] In some embodiments, the target device includes a serving base station where the terminal device to be located and / or a neighboring base station of the serving base station is located. That is, the LMF can send the first information to the serving base station, or to the neighboring base station, or to the serving base station and the neighboring base station. The neighboring base station can be one or more. The neighboring base station can be a gNB or other base stations such as a TRP.

[0208] The first information is similar to the first indication information, with one difference being that the first information is sent by LMF to the network device, and the first indication information is sent by LMF to the target device.

[0209] The first information may be used to indicate the measurement time window, but the present application is not limited thereto. For example, the first information may also carry an indication of the measurement time window, or the first information may include an indication of the measurement time window. The meaning of the measurement time window is consistent with the above, and is not repeated here.

[0210] The first information may be carried in any message, for example, in a measurement request. The measurement request may also carry configuration of part or all of the SRS resources.

[0211] It is understandable that each of the multiple time windows may be configured with SRS resources of one frequency point or multiple frequencies, or may not be configured with SRS resources. Among them, a time window configured with at least one frequency point can be selected as a measurement time window.

[0212] In some embodiments, the SRS resources in the measurement time window all belong to the target frequency point. In other words, the SRS resources in the measurement time window belong to only one frequency point. In other words, there is only one SRS resource at one frequency point in the measurement time window.

[0213] SRS resources belonging to the same frequency point may mean that these SRS resources belong to the same CC. For example, the SRS resources of the target frequency point belong to the same CC. SRS resources belonging to the same frequency point may also mean that these SRS resources have the same ARFCN. For example, the SRS resources of the target frequency point have the same ARFCN. SRS resources belonging to the same frequency point may also mean that these SRS resources have the same carrier. For example, the SRS resources of the target frequency point have the same carrier.

[0214] In the case where there are resource sets of multiple frequencies in the same measurement time window, the network device needs to measure and report the SRS resource sets of multiple frequencies separately when measuring and reporting, which has high processing complexity. In the embodiment of the present application, the SRS resources in the measurement time window all belong to one frequency, which can reduce the processing complexity of the network device performing positioning measurement and improve the efficiency of positioning measurement.

[0215] In some other embodiments, the SRS resources in the measurement time window belong to multiple frequency points. The first information may be used to indicate one of the multiple frequency points as a target frequency point.

[0216] The SRS resource may refer to an SRS resource, an SRS resource set or a BWP. The SRS resource within the measurement time window may be a plurality of SRS resources, or a plurality of SRS resource sets or a plurality of BWPs.

[0217] The first positioning measurement may be a positioning measurement of a carrier phase or a positioning measurement of time. The specific meaning may refer to the above description of the first positioning measurement, which will not be repeated here.

[0218] S1020: The network device performs a first positioning measurement on the SRS resources of the target frequency within the measurement time window according to the first information.

[0219] Based on the above scheme, LMF instructs the network device to perform the first positioning measurement on the SRS resources of the target frequency point within the measurement time window through the first information, thereby avoiding the network device from arbitrarily selecting a frequency point from multiple frequency points within the measurement time window for positioning measurement, thereby avoiding each network device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of the positioning measurement.

[0220] In some embodiments, S1020 includes: the network device only performs the first positioning measurement on the SRS resources of the target frequency point within the measurement time window.

[0221] As an example, the LMF may choose to configure a time window of only one frequency point as the measurement time window. In this way, the SRS resources in the measurement time window indicated by the first information sent by the LMF all belong to one frequency point.

[0222] As another example, the LMF may select a time window configured with multiple frequency points as a measurement time window, and indicate one of the multiple frequency points within the measurement time window as a target frequency point.

[0223] Based on the above scheme, LMF can instruct the network device to perform positioning measurement only on the SRS resources of the target frequency point within the measurement time window, avoiding the network device measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0224] In some embodiments, S1020 includes: the network device preferentially performs the first positioning measurement on the SRS resources of the target frequency point within the measurement time window.

[0225] As an example, LMF can indicate one of the multiple frequency points in the measurement time window as the target frequency point, and instruct the network device to preferentially measure the SRS resource of the target frequency point in the measurement time window. For example, there are frequency points 1 and 2 in measurement time window 1, and it is assumed that the target frequency point is 1. In this way, the network device can preferentially measure frequency point 1 in the first measurement time window, and measure frequency point 2 in the measurement time window 1 of the next cycle, thereby avoiding the network device measuring different frequency points in the same measurement time window.

[0226] Based on the above solution, LMF can instruct the network device to preferentially perform positioning measurement on the SRS resources of the target frequency point within the measurement time window. The above solution avoids the network device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0227] In some embodiments, the SRS resources within the measurement time window belong to multiple frequency points, and the first information also carries a priority, where the priority is used to indicate the order in which the first positioning measurement is performed on the multiple frequency points within the measurement time window.

[0228] The SRS resources in the measurement time window belong to multiple frequency points, that is, the SRS resources in the measurement time window indicated by the first information sent by the LMF can be resources of different frequency points. In other words, there can be cross-frequency resources in the measurement time window, and these resources belong to different CCs, or different ARFCNs, or different absolute frequencies. In this way, when there is carrier aggregation, that is, when there are multiple CCs in a measurement time window, the measurement time window also contains multiple frequencies.

[0229] The first information also carries the priority, which can be understood as the first information also indicating the priority, or can also be understood as the first information also including the priority.

[0230] Priority can be understood as the frequency priority of different frequencies within the measurement time window. Priority is the order of SRS resources of different frequencies within the measurement time window for positioning measurement. The network device can measure and report multiple frequency points within the measurement time window according to the order of priority. For example, there are four frequency points {1, 2, 3, 4}, two measurement time windows {1, 2}, measurement time window 1 contains SRS resources of frequency points {1, 3}, and measurement time window 2 contains SRS resources of frequency points {2, 4}. By indicating that the priority of the frequency point is {1, 2, 3, 4}, the network device can first measure the SRS resources of frequency point 1 within the measurement time window 1, and then measure the SRS resources of frequency point 3. In the case where the network device includes a serving base station and a neighboring base station, the serving base station and the neighboring base station can measure the SRS resources of frequency points 1 and frequency point 3 simultaneously. Similarly, for measurement time window 2, the network equipment can first measure the SRS resources of frequency 2, and then measure the SRS resources of frequency 4. When the network equipment includes a serving base station and a neighboring base station, the above scheme realizes the simultaneous measurement of the SRS resources of frequency 2 and frequency 4 by the serving base station and the neighboring base station.

[0231] It should be noted that the present application does not limit the priority to indicate the order in which the first positioning measurement is performed for all frequency points within the measurement time window. For example, the priority may indicate the order in which the first positioning measurement is performed for some frequency points within the measurement time window. For frequency points whose priorities do not indicate an order, the network device may perform positioning measurements according to the existing scheme, or may not perform positioning measurements. In other words, the network device may first measure the SRS resources of the frequency points indicated in the priority in the order of priority, and then measure the SRS resources of the frequency points not indicated in the priority in a random order. Alternatively, the network device may only measure the SRS resources of the frequency points indicated in the priority in the order of priority, and not measure the SRS resources of the frequency points not indicated in the priority.

[0232] Based on the above scheme, LMF instructs the network device to perform the first positioning measurement on the SRS resources of multiple frequency points within the measurement time window in a certain order through priority, avoiding the network device from arbitrarily selecting a frequency point for positioning measurement from multiple frequency points within the measurement time window, thereby avoiding the network device from measuring different frequency points within the same measurement time window, thereby improving the accuracy of positioning measurement.

[0233] In some embodiments, the method also includes: the LMF sends second information to the network device, the second information is used to instruct the network device to perform a second positioning measurement on the multiple SRS resources; the network device preferentially performs the second positioning measurement on the SRS resource of the target frequency point among the multiple SRS resources based on the second information and the first information.

[0234] The second information can be the same indication information as the first information. In other words, one information can be used to instruct the network device to perform both the first positioning measurement and the second positioning measurement. In this way, the second information can also be called the first information. It can also be understood that the second information and the first information are sent at the same time.

[0235] Exemplarily, the first information and the second information are carried in the same information. It can also be understood that the first information and the second information are included in the same information. Exemplarily, the first information and the second information can be carried in a measurement request or in other messages.

[0236] It should be noted that the second positioning measurement is a measurement of SRS resources, not limited to the SRS resources within the measurement time window. The description of the second positioning measurement measuring SRS resources can refer to the description of measuring PRS resources above, which will not be repeated here.

[0237] Based on the above scheme, the network device preferentially measures the SRS resources of the target frequency point, avoiding the network device from arbitrarily selecting a certain frequency point from multiple frequency points for positioning measurement, thereby avoiding the network device from measuring different frequency points, thereby improving the accuracy of positioning measurement. In addition, when the network device performs the second positioning measurement, it is not limited to measuring the SRS resources of the target frequency point within the measurement time window, making the measurement result of the second positioning measurement finally determined more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0238] Fig.11 It is a schematic flow chart of yet another positioning measurement method 1000 provided in an embodiment of the present application. Fig.11 The illustrated method 1000 includes the following steps.

[0239] Step 1: LMF sends a positioning information request to the serving base station through NRPPa, requesting to configure SRS resources for the target.

[0240] Step 2: The serving base station determines available SRS resources and sends configuration information of the SRS resources to the target device.

[0241] Step 3: The serving base station sends a positioning information response through NRPPa and reports the configuration information of the SRS resources to the LMF.

[0242] Step 4: LMF sends SRS configuration to the base station participating in positioning (e.g., neighboring base station) through NRPPa, and sends a measurement request. The measurement request may include first information, which may indicate the measurement time window and the target frequency point within the time measurement window. If there are multiple frequency points within the time measurement window, the first information may also indicate the priority of these frequency points.

[0243] Step 5: Each base station (eg, a serving base station and multiple neighboring base stations) measures the SRS sent by the target device.

[0244] Step 6: Each base station sends a measurement response to the LMF according to the measurement time information, indicating the measurement results such as the carrier phase and time of the target device.

[0245] Step 7: LMF performs location calculation of the terminal device based on the measurement results.

[0246] The following is an introduction to the device embodiment corresponding to the method embodiment of the present application. The following is only a brief introduction to the device, and the specific implementation steps and details of the scheme can refer to the method embodiment above.

Whether one of the above functions is executed in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.

The communication device 1200 includes a processor 1210 and a communication interface 1220, and the processor 1210 and the communication interface 1220 can be connected to each other via a bus 1230.

For example, the processor 1210 is used to control the transceiver to receive and / or send a signal.

[0256] It should be noted that the communication device 1200 may include a transmitter but not a receiver. Alternatively, the communication device 1200 may include a receiver but not a transmitter.
