Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, communication device, and storage medium for reporting positioning measurement results. Background Technology

[0002] In New Radio (NR) systems, a downlink-time difference of arrival (DL-TDOA) positioning method is supported.

[0003] In this positioning method, taking a certain Transmission Reception Point (TRP) as a reference, the reference signal time difference (RSTD) of the positioning reference signal arriving at the terminal device can be calculated relative to the positioning reference signal corresponding to the TRP. Based on multiple RSTDs, the network side can calculate the location of the terminal device.

[0004] In the above positioning method, the terminal reports a set of RSTD results, which are calculated based on the same reference TRP. In actual systems, because the timing error of the terminal device receiving the positioning reference signal varies each time, this positioning method cannot effectively reduce the performance degradation caused by different timing errors at the receiving end.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0042] Please refer to Figure 1 This illustration shows a schematic diagram of a network architecture 100 provided in one embodiment of this application. The network architecture 100 may include: a terminal device 10, an access network device 20, and a core network device 30.

[0043] Terminal device 10 can refer to UE (User Equipment), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent, or user equipment. Optionally, terminal device 10 can also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in 5GS (5th Generation System), or terminal device in the future evolved PLMN (Public Land Mobile Network), etc., and this application embodiment is not limited in this respect. For ease of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed within the cell managed by each access network device 20.

[0044] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. Optionally, a communication relationship can be established between terminal device 10 and core network device 30 through access network device 20. For example, in an LTE (Long Term Evolution) system, access network device 20 may be one or more eNodeBs in an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or EUTRAN; in a 5G NR system, access network device 20 may be one or more gNBs in a RAN (Radio Access Network). In this embodiment of the application, unless otherwise specified, the network device refers to access network device 20, such as a base station.

[0045] Core network equipment 30 is equipment deployed in the core network. Its main functions are to provide user connectivity, manage users, and bear services, serving as an interface to external networks. For example, core network equipment in a 5G NR system may include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities.

[0046] In one example, access network device 20 and core network device 30 communicate with each other via some air interface technology, such as the NG interface in a 5G NR system. Access network device 20 and terminal device 10 communicate with each other via some air interface technology, such as the Uu interface.

[0047] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems, and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems. This application does not limit these applications.

[0048] Before introducing the technical solution of this application, some background technical knowledge involved in this application will be introduced and explained.

[0049] Positioning technology is one of the core technologies of modern communication and navigation systems. For example, satellite navigation systems, Bluetooth, and Wireless Fidelity (WiFi) all provide positioning functions.

[0050] Similarly, modern cellular communication systems all support location services. Starting with 3G and 4G systems, various advanced location technologies have gradually been incorporated into cellular communication systems. 5G systems also support location technology, with specific standards introduced in Release 16. In the 3G Partnership (3G Partnership)... rd The Generation Partnership Project (3GPP) Release 16 (NR) introduced the following positioning technologies:

[0051] Downlink Time Difference of Arrival (TDOA) Location Method

[0052] • Uplink Time Difference of Arrival (UL-TDOA)

[0053] Positioning method

[0054] Multi-Round Trip Time (Multi-RTT) positioning method

[0055] Downlink-Angle of Departure (DL-AoD) location method

[0056] • Uplink Angle of Arrival (UL-AoA) positioning method

[0057] • Enhanced Cell ID Location Method

[0058] To support various positioning methods, the R16 version of NR introduced a Positioning Reference Signal (PRS) in the downlink and a Sounding Reference Signal for Positioning (SRS) in the uplink.

[0059] The NR-based positioning function mainly involves three parts:

[0060] • Terminal Equipment (UE)

[0061] • Multiple network-side Transmission Reception Points (TRPs)

[0062] Multiple TRPs (Transport Resource Ports) exist around the terminal device and participate in cellular positioning. A base station may be a single TRP, and a single base station may have multiple TRPs.

[0063] • Location Server

[0064] The location server is responsible for the entire location process and may include a location management function (LMF).

[0065] Downlink-based positioning methods (such as DL-TDOA-based positioning methods) can be further divided into two main categories:

[0066] • Terminal device-assisted positioning method (UE-assisted)

[0067] In this positioning method, the terminal device is responsible for positioning-related measurements, and the network calculates location information based on the positioning measurement results reported by the terminal device.

[0068] • Device-based positioning method (UE-based)

[0069] In this positioning method, the terminal device performs positioning-related measurements and calculates location information based on the positioning measurement results.

[0070] Below, in conjunction with references Figure 2 This paper provides an exemplary description of a terminal device-assisted positioning method based on the downlink.

[0071] like Figure 2 As shown, the positioning system includes a positioning server 210, a TRP 220, a TRP 230, and a terminal device 240. This embodiment is only used as an example to illustrate the use of one TRP (TRP 220) in positioning. In specific embodiments, multiple TRPs may also be used in positioning.

[0072] During positioning, the positioning server 210 notifies the TRP 220 of positioning-related configurations, which include at least one of the following: PRS configuration information, the type of measurement results that the terminal device 240 needs to report, etc. Based on the positioning-related configurations, the TRP 220 sends a positioning signal (PRS) to the terminal device 240. The terminal device 240 receives the PRS and performs measurements. Depending on the positioning method, the positioning measurement results required by the terminal device 240 will vary.

[0073] After the measurement is completed, the terminal device 240 sends the positioning measurement results back to the positioning server 210. Specifically, the terminal device 240 first sends the positioning measurement results to the base station, and then the base station sends them back to the positioning server 210. The positioning server 210 calculates location-related information based on the positioning measurement results.

[0074] The above is a flowchart illustrating a terminal device-assisted positioning method. For a UE-based positioning method, the terminal device directly calculates location-related information based on the positioning measurement results, without needing to report the results to the positioning server, which then performs the calculations. In this method, the terminal device needs to know the location information corresponding to the TRP (Telematics Reference Point), therefore the network needs to notify the terminal device of the TRP's location information in advance.

[0075] Below, in conjunction with references Figure 3 This section provides an example of a positioning method based on the uplink. For instance... Figure 3As shown, the positioning system includes a positioning server 310, a TRP 320, a TRP 330, and a terminal device 340. This embodiment is only used as an example to illustrate the use of one TRP (TRP 320) in positioning; in specific embodiments, multiple TRPs may also be used for positioning.

[0076] During positioning, the positioning server 310 notifies the TRP 320 of positioning-related configurations, which include at least the configuration information of the SRS used for positioning. The TRP 320 sends the positioning-related configurations to the terminal 340, and the terminal device 340 sends an uplink signal to the TRP 320 based on the positioning-related configurations: the SRS used for positioning. The TRP 320 then receives the SRS used for positioning accordingly.

[0077] TRP 320 measures the SRS used for positioning and sends the positioning measurement results to positioning server 310. Positioning server 310 calculates location-related information based on the positioning measurement results.

[0078] Below, in conjunction with references Figure 4 An exemplary description is provided for a positioning method based on downlink time difference of arrival.

[0079] Taking the positioning of a terminal device using four transmitting and receiving points as an example, TRP 400, TRP 410, TRP 420, and TRP 430 are used to locate terminal device 440. The distances between each TRP and terminal device 440 are denoted as d0, d1, d2, and d3, respectively, and the corresponding propagation times of the positioning signals are T0, T1, T2, and T3.

[0080] To obtain the corresponding measurement results, the four TRPs need to send corresponding positioning signals, denoted as S0, S1, S2, and S3 respectively. Their transmission times on their respective TRPs are t0, t1, t2, and t3, and their corresponding reception times on the terminal device 440 side are t0', t1', t2', and t3'.

[0081] Let the speed of light be C. Based on the above description, we can obtain:

[0082] T0 = ​​t0' – t0 = d0 / C;

[0083] T1 = t1' - t1 = d1 / C;

[0084] T2 = t2' – t2 = d2 / C;

[0085] T3=t3'–t3=d3 / C.

[0086] If TRP400 is used as a reference, the reference signal time difference (RSTD) for the location signal corresponding to each TRP reaching the terminal device 440 can be calculated, and expressed as:

[0087] RSTD 1=T1-T0=d1 / C–d0 / C;

[0088] RSTD 2=T2-T0=d2 / C–d0 / C;

[0089] RSTD 3=T3-T0=d3 / C–d0 / C.

[0090] Specifically, with TRP 400 as a reference, RSTD 1 is the reference signal time difference corresponding to TRP 410; RSTD 2 is the reference signal time difference corresponding to TRP 420; and RSTD 3 is the reference signal time difference corresponding to TRP 430. The positioning server determines the location of terminal device 440 based on the above reference signal time differences.

[0091] The downlink time difference of arrival (TDOA) positioning method described above, as well as other positioning methods in R16 NR, all assume that the timing of the receiver corresponding to each positioning signal (such as PRS) received by the terminal device is the same. Therefore, the arrival time obtained from the positioning signals transmitted on each TRP can be differentially divided to obtain the time difference of arrival (TDOA), which can also be called downlink RSTD in NR.

[0092] In some cases, the timing of the receiver when the terminal device receives the positioning signal at different times will be different, or the timing of the receiver when receiving the positioning signal on different TRPs will be different. That is, there is a timing difference (Rx) at the receiver. This will lead to additional errors if the estimated arrival time is directly differentially processed.

[0093] For example, such as Figure 4 In the example shown, terminal device 440 uses the same hardware (e.g., an antenna panel) when receiving downlink positioning signals corresponding to TRP 400 and TRP 420, and its positioning has the same error Δ0. Terminal device 440 uses the same hardware (e.g., another antenna panel) when receiving downlink positioning signals corresponding to TRP 410 and TRP 430, and its positioning has the same error Δ1. Then the above expression can be expressed as:

[0094] T0=t0'–t0+△0=d0 / C+△0;

[0095] T1=t1'-t1+Δ1=d1 / C+Δ1;

[0096] T2=t2'–t2+△0=d2 / C+△0;

[0097] T3=t3'–t3+Δ1=d3 / C+Δ1.

[0098] If we follow a similar approach as before, for example, still using TRP400 as the reference TRP, then:

[0099] RSTD 1=T1-T0=d1 / C–d0 / C+△1-△0;

[0100] RSTD 2=T2-T0=d2 / C–d0 / C;

[0101] RSTD 3=T3-T0=d3 / C–d0 / C+Δ1-Δ0.

[0102] As can be seen, both TRP 410 and TRP 430 have an error △1-△0 relative to TRP 400 in their RSTD. To eliminate this error, TRP 430 can choose TRP 410 as the reference TRP, then:

[0103] RSTD 3'=T3–T1=d3 / C–d1 / C.

[0104] As shown in RSTD3', since TRP 410 and TRP 430 correspond to the same receiver timing △1, the differential between TRP 410 and TRP 430 has no △1 or △0 related errors.

[0105] To address the above situation, a new solution needs to be designed to reduce the impact of receiver timing deviations caused by different receiver timing on positioning performance.

[0106] In response to the above situation, this application provides a method for reporting positioning measurement results. Different groups of positioning measurement results correspond to different receiver timings, thereby avoiding the impact of receiver timings on positioning measurement results and improving positioning accuracy.

[0107] The technical solution of this application will be described and illustrated below through several embodiments.

[0108] Please refer to Figure 5 The diagram illustrates a flowchart of a positioning measurement result reporting method provided in an exemplary embodiment of this application. This method can be applied to... Figure 1 In the network architecture shown, the method may include the following steps (502-504):

[0109] Step 502: Using the first information, the terminal device sends X sets of positioning measurement results to the network device, where X is a positive integer not less than 2.

[0110] The positioning measurement results are obtained based on the DL-TDOA positioning method.

[0111] In this embodiment of the application, the terminal device sends multiple sets of positioning measurement results to the network device through the first information. For example, different sets of positioning measurement results correspond to different receiving end timings, and the positioning measurement results in one set correspond to the same receiving end timing.

[0112] Optionally, the positioning measurement result is the RSTD measurement result.

[0113] Optionally, each of the X groups of positioning measurement results corresponds to a reference TRP (i.e., "RSTDreference" TRP), meaning that all positioning measurement results within the same group are obtained based on the same reference TRP. Different groups of the X groups of positioning measurement results correspond to different reference TRPs.

[0114] Optionally, the terminal device differentially calculates the arrival times of downlink positioning signals corresponding to the same receiver timing to obtain a set of positioning measurement results. This set of measurement results includes the RSTD calculated based on the same reference TRP. After the terminal device obtains X sets of positioning measurement results based on different receiver timings, it sends the X sets of positioning measurement results to the network device through the first information.

[0115] For example, in conjunction with reference Figure 4 When receiving downlink positioning signals corresponding to TRP 400 and TRP 420, terminal device 440 uses the same hardware (e.g., an antenna panel), and its positioning has the same error Δ0. When receiving downlink positioning signals corresponding to TRP 410 and TRP 430, terminal device 440 uses the same hardware (e.g., another antenna panel), and its positioning has the same error Δ1. Terminal device sends two sets of positioning measurement results to network device via first information. The first set of positioning measurement results includes the RSTD of TRP 420 relative to TRP 400, and the second set of positioning measurement results includes the RSTD of TRP 430 relative to TRP 410.

[0116] Optionally, X is 2. By designing as few groups as possible, the design of relevant standard protocols is simplified.

[0117] Optionally, X is 3. For a typical millimeter-wave terminal, there are 3 high-frequency receiving modules, and each high-frequency receiving module corresponds to a set of positioning measurement results.

[0118] Optionally, the DL-TDOA-based positioning method is a DL-TDOA-based positioning method in a terminal device-assisted manner. As mentioned above, the DL-TDOA-based positioning method may be UE-assisted or UE-based. In this embodiment, the DL-TDOA-based positioning method is a DL-TDOA-based positioning method in a terminal device-assisted manner. The terminal device sends positioning measurement results to the network device through first information, and the network device locates the terminal device based on the positioning measurement results. Optionally, the positioning measurement results are obtained by the terminal device measuring downlink positioning signals, including PRS. With the evolution of communication standards, other types of downlink positioning signals may also be used to obtain positioning measurement results, and this application does not impose any limitations on this.

[0119] Step 504: Through the first information, the network device receives X sets of positioning measurement results sent by the terminal device.

[0120] Optionally, after receiving X sets of positioning measurement results, the network device performs positioning for the terminal device based on the X sets of positioning measurement results.

[0121] In summary, the technical solution provided in this embodiment transmits X sets of positioning measurement results to the network device. Different sets of positioning measurement results correspond to different receiving end timings. Since the positioning measurement results in each set correspond to the same receiving end timing, the problem of additional errors caused by only reporting one set of positioning measurement results in related technologies, where the positioning measurement results in a set are affected by different receiving end timings, can be avoided, thereby improving positioning accuracy.

[0122] The first information can be implemented in the following two ways:

[0123] Method 1: The first information is transmitted via the Long Term Evolution Positioning Protocol (LPP).

[0124] Accordingly, step 502 is replaced by: transmitting the first information via LPP, the terminal device sends X sets of positioning measurement results to the network device, where X is a positive integer not less than 2; step 504 is replaced by: transmitting the first information via LPP, the network device receives the X sets of positioning measurement results sent by the terminal device.

[0125] Optionally, in this method, the network device is a location server.

[0126] Understandably, in Method 1, the existing protocol process is reused, and the terminal device sends the positioning measurement results to the positioning server through LPP. Based on this method, the workload of standardization protocol can be reduced.

[0127] Method 2: The first information is transmitted via Radio Resource Control (RRC) signaling.

[0128] Accordingly, step 502 is replaced by: the terminal device sending X sets of positioning measurement results to the network device via RRC signaling, where X is a positive integer not less than 2; step 504 is replaced by: the network device receiving X sets of positioning measurement results sent by the terminal device via RRC signaling.

[0129] Optionally, in this approach, the network device is the serving gNB for the terminal device.

[0130] Understandably, in method 2, the terminal device sends X sets of positioning measurement results to the serving base station via RRC signaling. This method can reduce the latency caused by information transmission or processing.

[0131] It is understood that, in addition to RRC signaling, terminal devices may also use other types of signaling to transmit X sets of positioning measurement results to network devices. This signaling may be other existing types of signaling or newly introduced signaling compared to the existing version of the standard protocol. This application does not impose any restrictions on this.

[0132] The following is a further introduction to Method 1.

[0133] 1.1: The first information is transmitted by providing location information cells.

[0134] Among them, ProvideLocationInformation is a type of location information element.

[0135] In 1.1, the ProvideLocationInformation cell transmits X-group location measurement results by indicating X-group NR-Downlink-Time Difference of Arrival-ProvideLocationInformation (NR-DL-TDOA-ProvideLocationInformation) type information, reusing the NR-DL-TDOA-ProvideLocationInformation signaling in the existing LPP protocol and process, with a small amount of standardization work.

[0136] Specifically, there are three possible implementation methods, namely 1.1.1, 1.1.2, and 1.1.3.

[0137] 1.1.1: The ProvideLocationInformation cell transmits the X sets of location measurement results through two fields.

[0138] The ProvideLocationInformation information element includes: the nr-downlink-time difference of arrival-provided location information (nr-DL-TDOA-ProvideLocationInformation) field and the first information field.

[0139] The nr-DL-TDOA-ProvideLocationInformation field is used to indicate one set of positioning measurement results in the X group of positioning measurement results; the first information field is used to indicate the other X-1 groups of positioning measurement results in the X group of positioning measurement results.

[0140] The first information field is a new field added to the ProvideLocationInformation information element in subsequent evolved versions, compared to the ProvideLocationInformation information element specified in the initial version (R16).

[0141] In the following descriptions, the initial versions of the LPP protocol all refer to R16 (or Release 16), and will not be repeated here.

[0142] Optionally, the first information field adopts a sequence structure, and the type of each element in the sequence structure of the first information field is: NR-DL-TDOA-ProvideLocationInformation.

[0143] Understandably, in section 1.1.1, the existing nr-DL-TDOA-ProvideLocationInformation field and NR-DL-TDOA-ProvideLocationInformation signaling in the LPP protocol and process are reused. One existing nr-DL-TDOA-ProvideLocationInformation field is reused to transmit a set of location measurement results. At the same time, a new first information field is added, which can indicate one or more sets of location measurement results. The standardization workload is small.

[0144] For example, based on subsequent evolution versions, 1.1.1 is described in the protocol standard as follows, where " / / " indicates that the following text is a description of the preceding part (similar uses in other subsequent examples, which will not be elaborated on one by one):

[0145]

[0146]

[0147] 1.1.2: The ProvideLocationInformation cell transmits X sets of location measurement results through one field.

[0148] The ProvideLocationInformation element includes a second information field, which indicates the location measurement results of group X.

[0149] The second information field is a new field added to the ProvideLocationInformation information element in subsequent evolved versions, compared to the ProvideLocationInformation information element specified in the initial version.

[0150] Optionally, the second information field adopts a sequence structure, and the type of each element in the sequence structure of the second information field is: NR-DL-TDOA-ProvideLocationInformation.

[0151] Understandably, in version 1.1.2, the existing LPP protocol and process's NR-DL-TDOA-ProvideLocationInformation signaling are reused. Instead of using the existing domain, a new second information domain is added. This new second information domain can indicate multiple sets of positioning measurement results, reducing the amount of standardization work. At the same time, it has better scalability for different X values, making the protocol more flexible.

[0152] For example, based on subsequent evolution versions, 1.1.2 is described in the protocol standard as follows:

[0153]

[0154]

[0155] Based on the example above, we can extend this further: if X is 1, the ProvideLocationInformation cell transmits one set of location measurement results through the nr-DL-TDOA-ProvideLocationInformation field; if X is greater than 1, the ProvideLocationInformation cell transmits X sets of location measurement results through the second information field.

[0156] 1.1.3: ProvideLocationInformation cells transmit X sets of location measurement results through X fields.

[0157] The ProvideLocationInformation element includes: the nr-DL-TDOA-ProvideLocationInformation field and X-1 third information fields.

[0158] The nr-DL-TDOA-ProvideLocationInformation field is used to indicate one set of positioning measurement results in the X groups of positioning measurement results; the X-1 third information fields are used to indicate the other X-1 groups of positioning measurement results in the X groups of positioning measurement results.

[0159] The third information field is a new field added to the ProvideLocationInformation element in subsequent versions, compared to the ProvideLocationInformation element specified in the initial version. A third information field is used to indicate a set of location measurement results.

[0160] Optionally, the type corresponding to the third information field is: NR-DL-TDOA-ProvideLocationInformation.

[0161] Understandably, in version 1.1.3, the existing nr-DL-TDOA-ProvideLocationInformation field and NR-DL-TDOA-ProvideLocationInformation signaling in the LPP protocol and process are reused. One existing nr-DL-TDOA-ProvideLocationInformation field is reused, while one or more third information fields are added. Each third information field can indicate a set of location measurement results. The standardization workload is small, and the protocol structure is simple when the value of X is small.

[0162] For example, if the maximum value of X is 2, based on subsequent evolution versions, 1.1.3 is described in the protocol standard as follows:

[0163]

[0164] The case where X takes a larger value can be derived from the example above, and will not be elaborated here.

[0165] 1.2: The first information provides location information via NR downlink time difference.

[0166] (NR-DL-TDOA-ProvideLocationInformation) cells are used for transmission.

[0167] Among them, the NR-DL-TDOA-ProvideLocationInformation information element is a type of location information element.

[0168] In section 1.2, the NR-DL-TDOA-ProvideLocationInformation cell transmits X-group location measurement results by indicating X-group NR-Downlink-Time Difference of Arrival-SignalMeasurementInformation (NR-DL-TDOA-SignalMeasurementInformation) type information, reusing the NR-DL-TDOA-SignalMeasurementInformation signaling in the existing LPP protocol and process, with a small amount of standardization work.

[0169] Specifically, there are three possible implementation methods, namely 1.2.1, 1.2.2, and 1.2.3.

[0170] 1.2.1: The NR-DL-TDOA-ProvideLocationInformation cell transmits X sets of location measurement results through two fields.

[0171] The NR-DL-TDOA-ProvideLocationInformation information element includes: the nr-downlink-time difference of arrival-signal measurement information (nr-DL-TDOA-SignalMeasurementInformation) field and the fourth information field.

[0172] The nr-DL-TDOA-SignalMeasurementInformation field is used to indicate one set of positioning measurement results in the X group of positioning measurement results; the fourth information field is used to indicate the other X-1 groups of positioning measurement results in the X group of positioning measurement results.

[0173] The fourth information field is a new field added to the NR-DL-TDOA-ProvideLocationInformation information element in subsequent evolved versions, compared to the NR-DL-TDOA-ProvideLocationInformation information element specified in the initial version.

[0174] Optionally, the fourth information field adopts a sequence structure, and the type of each element in the sequence structure of the fourth information field is: NR-DL-TDOA-SignalMeasurementInformation.

[0175] Understandably, in section 1.2.1, the existing nr-DL-TDOA-SignalMeasurementInformation field and NR-DL-TDOA-SignalMeasurementInformation signaling in the LPP protocol and process are reused. One existing nr-DL-TDOA-SignalMeasurementInformation field is reused to transmit a set of positioning measurement results. At the same time, a new fourth information field is added, which can indicate one or more sets of positioning measurement results. The standardization workload is small.

[0176] For example, based on subsequent evolution versions, 1.2.1 is described in the protocol standard as follows:

[0177]

[0178] 1.2.2: The NR-DL-TDOA-ProvideLocationInformation cell transmits X sets of location measurement results through one field.

[0179] The NR-DL-TDOA-ProvideLocationInformation information element includes: a fifth information field, which is used to indicate the location measurement results of group X.

[0180] The fifth information field is a new field added to the NR-DL-TDOA-ProvideLocationInformation information element in subsequent evolved versions, compared to the NR-DL-TDOA-ProvideLocationInformation information element specified in the initial version.

[0181] Optionally, the fifth information field adopts a sequence structure, and the type of each element in the sequence structure of the fifth information field is: NR-DL-TDOA-SignalMeasurementInformation.

[0182] Understandably, in section 1.2.2, the existing LPP protocol and process's NR-DL-TDOA-SignalMeasurementInformation signaling are reused, but the existing fields are not used. A new fifth information field is added. This new fifth information field can indicate multiple sets of positioning measurement results, reducing the amount of standardization work. At the same time, it has good scalability for different X values, making the protocol more flexible.

[0183] For example, based on subsequent evolution versions, 1.2.2 is described in the protocol standard as follows:

[0184]

[0185]

[0186] Based on the example above, we can extend this further: if X is 1, then the NR-DL-TDOA-ProvideLocationInformation cell transmits one set of location measurement results through the nr-DL-TDOA-SignalMeasurementInformation field; if X is greater than 1, then the NR-DL-TDOA-ProvideLocationInformation cell transmits X sets of location measurement results through the fifth information field.

[0187] 1.2.3: The NR-DL-TDOA-ProvideLocationInformation cell transmits X sets of positioning measurement results through X fields.

[0188] The NR-DL-TDOA-ProvideLocationInformation information element includes: the nr-DL-TDOA-SignalMeasurementInformation field and X-1 sixth information fields.

[0189] Among them, the nr-DL-TDOA-SignalMeasurementInformation field is used to indicate one set of positioning measurement results in the X groups of positioning measurement results; the X-1 sixth information fields are used to indicate the other X-1 groups of positioning measurement results in the X groups of positioning measurement results.

[0190] The sixth information field is a new field added in the NR-DL-TDOA-ProvideLocationInformation information element in subsequent evolved versions, compared to the initial version. A sixth information field is used to indicate a set of positioning measurement results.

[0191] Optionally, the type corresponding to the sixth information field is: NR-DL-TDOA-SignalMeasurementInformation.

[0192] Understandably, in version 1.2.3, the existing nr-DL-TDOA-SignalMeasurementInformation field and NR-DL-TDOA-SignalMeasurementInformation signaling in the LPP protocol and process are reused, as is an existing nr-DL-TDOA-ProvideLocationInformation field. At the same time, one or more sixth information fields are added. Each sixth information field can indicate a set of positioning measurement results. The standardization workload is small, and the protocol structure is simple when the value of X is small.

[0193] For example, if the maximum value of X is 2, based on subsequent evolution versions, 1.2.3 is described in the protocol standard as follows:

[0194]

[0195] The case where X takes a larger value can be derived from the example above, and will not be elaborated here.

[0196] 1.3: The first information is transmitted via the NR-DL-TDOA-SignalMeasurementInformation cell.

[0197] Among them, the NR-DL-TDOA-SignalMeasurementInformation information element is a type of location information element.

[0198] In section 1.3, the NR-DL-TDOA-SignalMeasurementInformation cell transmits X-group positioning measurement results by indicating X-group NR-Downlink-Time Difference of Arrival-MeasList (NR-DL-TDOA-MeasList) type information, reusing the Downlink-Location Reference Information-Identifier-Information (DL-PRS-ID-Info) and NR-DL-TDOA-MeasList signaling in the existing LPP protocol and procedures, with minimal standardization effort.

[0199] Specifically, there are four possible implementation methods, namely 1.3.1, 1.3.2, 1.3.3 and 1.3.4.

[0200] 1.3.1: The NR-DL-TDOA-SignalMeasurementInformation cell transmits X sets of positioning measurement results through two sets of fields.

[0201] The NR-DL-TDOA-SignalMeasurementInformation information element includes: a first group of fields and a second group of fields. The first group of fields includes: the dl-positioning reference signal-reference information (dl-PRS-ReferenceInfo) field and the nr-downlink-time difference of arrival-measurement list (nr-DL-TDOA-MeasList) field.

[0202] The first group of domains corresponds to one set of positioning measurement results in the X group of positioning measurement results; the second group of domains corresponds to the other X-1 groups of positioning measurement results in the X group of positioning measurement results.

[0203] The first set of fields includes two fields from the NR-DL-TDOA-SignalMeasurementInformation information element specified in the initial version: the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field. The dl-PRS-ReferenceInfo field corresponds to the type DL-PRS-ID-Info, and the nr-DL-TDOA-MeasList field corresponds to the type NR-DL-TDOA-MeasList.

[0204] The second set of fields is a new set of fields added in subsequent versions of the NR-DL-TDOA-SignalMeasurementInformation information element, compared to the initial version. It is understood that the second set of fields may consist of only one field, but each element within that field can indicate multiple (e.g., two) different pieces of information.

[0205] Optionally, the second set of fields adopts a sequence structure. Each element in the sequence structure of the second set of fields indicates two pieces of information, and the types of the two pieces of information are DL-PRS-ReferenceInfo and NR-DL-TDOA-MeasList, respectively.

[0206] Understandably, in version 1.3.1, the existing LPP protocol and process reuse the DL-PRS-ReferenceInfo and NR-DL-TDOA-MeasList signaling, and reuse the existing two fields (the first group of fields): the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field. The first group of fields is used to correspond to a set of positioning measurement results. At the same time, a second group of fields is added. The newly added second group of fields can correspond to one or more sets of positioning measurement results, which reduces the amount of standardization work.

[0207] For example, based on subsequent evolution versions, 1.3.1 is described in the protocol standard as follows:

[0208]

[0209] 1.3.2: The NR-DL-TDOA-SignalMeasurementInformation cell transmits the X group positioning measurement results through the X group field.

[0210] The NR-DL-TDOA-SignalMeasurementInformation information element includes: a first group of fields and X-1 third group fields. The first group of fields includes: the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field.

[0211] The first group of domains corresponds to one set of positioning measurement results in the X group of positioning measurement results; the X-1 third group of domains corresponds to the other X-1 sets of positioning measurement results in the X group of positioning measurement results.

[0212] The first set of fields includes two fields from the NR-DL-TDOA-SignalMeasurementInformation information element specified in the initial version: the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field. The dl-PRS-ReferenceInfo field corresponds to the type DL-PRS-ID-Info, and the nr-DL-TDOA-MeasList field corresponds to the type NR-DL-TDOA-MeasList.

[0213] The third set of fields is a new set of fields added in the NR-DL-TDOA-SignalMeasurementInformation information element in subsequent evolved versions, compared to the initial version. One third set of fields corresponds to one set of positioning measurement results.

[0214] Optionally, the third set of fields includes two fields, with the corresponding types being DL-PRS-ReferenceInfo and NR-DL-TDOA-MeasList, respectively.

[0215] Understandably, in version 1.3.2, the existing LPP protocol and process reuse the DL-PRS-ReferenceInfo and NR-DL-TDOA-MeasList signaling, and reuse the existing two fields (the first group of fields): the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field. The first group of fields is used to correspond to a set of positioning measurement results. At the same time, one or more third groups of fields are added, each of which is used to correspond to a set of positioning measurement results. The standardization workload is small, and the protocol structure is simple when the value of X is small.

[0216] For example, if the maximum value of X is 2, based on subsequent evolution versions, 1.3.2 is described in the protocol standard as follows:

[0217]

[0218] Based on the example above, we can extend this further: the third group of fields includes one field, and the type of this field is NR-DL-TDOA-MeasList.

[0219] The case where X takes a larger value can be derived from the example above, and will not be elaborated here.

[0220] 1.3.3: The NR-DL-TDOA-SignalMeasurementInformation cell transmits X sets of positioning measurement results through three fields.

[0221] The NR-DL-TDOA-SignalMeasurementInformation information element includes: the dl-PRS-ReferenceInfo field, the nr-DL-TDOA-MeasList field, and the seventh information field.

[0222] Among them, some elements in the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field correspond to one set of positioning measurement results in the X group of positioning measurement results; other elements in the seventh information field and the nr-DL-TDOA-MeasList field correspond to the other X-1 groups of positioning measurement results in the X group of positioning measurement results.

[0223] The seventh information field is a new field added in the NR-DL-TDOA-SignalMeasurementInformation information element in the subsequent evolved versions, compared to the NR-DL-TDOA-SignalMeasurementInformation information element specified in the initial version.

[0224] Optionally, the seventh information field adopts a sequence structure, and each element in the sequence structure of the seventh information field corresponds to the type DL-PRS-ID-Info.

[0225] Optionally, the first element in the nr-DL-TDOA-MeasList field is configured with corresponding first element indication information.

[0226] In one possible implementation, the first element is all elements in the nr-DL-TDOA-MeasList field; that is, each element in the nr-DL-TDOA-MeasList field is configured with corresponding first element indication information. In another possible implementation, the first element is a subset of the elements in the nr-DL-TDOA-MeasList field.

[0227] The first element indicating information can be used for one of the following options:

[0228] • The first element indication information is used to indicate the group corresponding to the first element.

[0229] Since any one of the X group positioning measurement results corresponds to the information indicated by the dl-PRS-ReferenceInfo field, or corresponds to an element in the seventh information field, the first element indication information can indirectly indicate the information indicated by the dl-PRS-ReferenceInfo field or the element in the seventh information field by indicating the group corresponding to the first element.

[0230] For example, the first element indicates that the information carries an integer (starting from 0, such as 0, 1, ..., or starting from 1, such as 1, 2, ...) to indicate the group corresponding to the first element.

[0231] • The first element indication information is used to indicate an element in the seventh information field corresponding to the first element; or, it is used to indicate the information indicated by the dl-PRS-ReferenceInfo field corresponding to the first element.

[0232] The first element indicates an element in the seventh information field corresponding to the first element; or, it indicates the information indicated by the dl-PRS-ReferenceInfo field corresponding to the first element.

[0233] For example, the first element indicating information carries an integer (starting from 0, e.g., 0, 1, ..., or starting from 1, e.g., 1, 2, ...) to indicate an element in the seventh information field corresponding to the first element; or, to indicate the information indicated by the dl-PRS-ReferenceInfo field corresponding to the first element. For example, the first element indicating information carries DL-PRS-ID-Info to indicate an element in the seventh information field corresponding to the first element; or, to indicate the information indicated by the dl-PRS-ReferenceInfo field corresponding to the first element.

[0234] • The first element indication information is used to indicate the reference TRP corresponding to the first element.

[0235] Since DL-PRS-ID-Info is used to indicate the reference TRP, and the type corresponding to the dl-PRS-ReferenceInfo field is DL-PRS-ID-Info, and the type corresponding to each element in the sequence structure of the seventh information field is also DL-PRS-ID-Info, the first element indicating information can indirectly indicate the information indicated by the dl-PRS-ReferenceInfo field, or an element in the seventh information field, by indicating the reference TRP corresponding to the first element.

[0236] For example, the first element indication information carries an integer (starting from 0, e.g., 0, 1, ..., or starting from 1, e.g., 1, 2, ...) to indicate the reference TRP corresponding to the first element. For example, the first element indication information carries DL-PRS-ID-Info to indicate the reference TRP corresponding to the first element.

[0237] Optionally, the second element in the nr-DL-TDOA-MeasList field is not configured with the corresponding first element indication information, and the second element corresponds to the information indicated by the dl-PRS-ReferenceInfo field.

[0238] In one possible implementation, only some elements in the nr-DL-TDOA-MeasList field are configured with corresponding first element indication information. That is, the first element is a part of the elements in the nr-DL-TDOA-MeasList field, and the other elements in the nr-DL-TDOA-MeasList field other than the first element are denoted as the second element. The second element corresponds to the information indicated by the dl-PRS-ReferenceInfo field.

[0239] Optionally, the first element indication information is configured in the NR-Downlink-Time Difference of Arrival-MeasElement (NR-DL-TDOA-MeasElement).

[0240] Understandably, in version 1.3.3, the existing LPP protocol and procedures reuse the DL-PRS-ReferenceInfo and NR-DL-TDOA-MeasList signaling, and reuse the two existing fields: the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field. At the same time, a new seventh information field is added. The nr-DL-TDOA-MeasList field and a part of the dl-PRS-ReferenceInfo field correspond to a set of positioning measurement results, and the seventh information field and another part of the dl-PRS-ReferenceInfo field correspond to one or more sets of positioning measurement results. The standardization workload is small.

[0241] For example, based on subsequent evolution versions, 1.3.3 is described in the protocol standard as follows:

[0242]

[0243] Based on the example above, we can extend this further: the seventh information field (dl-PRS-ReferenceInfoList) does not exist; there is only the first element indication information (firstInfo). If the value of firstInfo is different, the corresponding positioning measurement results belong to different groups; if the value of firstInfo is the same, the corresponding positioning measurement results belong to the same group.

[0244] 1.3.4: The NR-DL-TDOA-SignalMeasurementInformation cell transmits X sets of positioning measurement results through X+1 fields.

[0245] The NR-DL-TDOA-SignalMeasurementInformation information element includes: the dl-PRS-ReferenceInfo field, the nr-DL-TDOA-MeasList field, and X-1 eighth information fields.

[0246] Among them, some elements in the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field correspond to one set of positioning measurement results in the X group of positioning measurement results; the other elements in the X-1 eighth information fields and the nr-DL-TDOA-MeasList field correspond to the other X-1 groups of positioning measurement results in the X group of positioning measurement results.

[0247] The eighth information field is a new field added in the NR-DL-TDOA-SignalMeasurementInformation information element in the subsequent evolved versions, compared to the NR-DL-TDOA-SignalMeasurementInformation information element specified in the initial version.

[0248] Optionally, the type corresponding to the eighth information field is DL-PRS-ID-Info.

[0249] Optionally, the third element in the nr-DL-TDOA-MeasList field is configured with corresponding second element indication information.

[0250] In one possible implementation, the third element is all elements in the nr-DL-TDOA-MeasList field; that is, each element in the nr-DL-TDOA-MeasList field is configured with corresponding second element indication information. In another possible implementation, the third element is a subset of the elements in the nr-DL-TDOA-MeasList field.

[0251] The second element indicates that the information can be used for one of the following purposes:

[0252] The second element indicates the group corresponding to the third element.

[0253] Since any one of the X group positioning measurement results corresponds to the information indicated by the dl-PRS-ReferenceInfo field, or corresponds to an eighth information field, the second element indicating information can indirectly indicate the information indicated by the third element corresponding to the dl-PRS-ReferenceInfo field, or the information indicated by the eighth information field, by indicating the group corresponding to the third element.

[0254] For example, the second element indicates that the information carries an integer (starting from 0, such as 0, 1, ..., or starting from 1, such as 1, 2, ...) to indicate the group corresponding to the third element.

[0255] • The second element indicates the information indicated by the eighth information field corresponding to the third element; or, it indicates the information indicated by the dl-PRS-ReferenceInfo field corresponding to the third element.

[0256] The second element indicates the information indicated by the third element corresponding to the eighth information field; or, it indicates the information indicated by the third element corresponding to the dl-PRS-ReferenceInfo field.

[0257] For example, the second element indicates information carrying an integer (starting from 0, e.g., 0, 1, ..., or starting from 1, e.g., 1, 2, ...) to indicate the information indicated by the eighth information field corresponding to the third element; or, to indicate the information indicated by the dl-PRS-ReferenceInfo field corresponding to the third element. For example, the second element indicates information carrying DL-PRS-ID-Info to indicate the information indicated by the eighth information field corresponding to the third element; or, to indicate the information indicated by the dl-PRS-ReferenceInfo field corresponding to the third element.

[0258] • The second element indication information is used to indicate the reference TRP corresponding to the third element.

[0259] Since DL-PRS-ID-Info is used to indicate the reference TRP, and the type corresponding to the dl-PRS-ReferenceInfo field is DL-PRS-ID-Info, and the type corresponding to the eighth information field is also DL-PRS-ID-Info, the second element indicating information can indirectly indicate the information indicated by the dl-PRS-ReferenceInfo field or the information indicated by the eighth information field by indicating the reference TRP corresponding to the third element.

[0260] For example, the second element indicates that the information carries an integer (starting from 0, e.g., 0, 1, ..., or starting from 1, e.g., 1, 2, ...) to indicate the reference TRP corresponding to the third element. For example, the second element indicates that the information carries DL-PRS-ID-Info to indicate the reference TRP corresponding to the third element.

[0261] Optionally, the fourth element in the nr-DL-TDOA-MeasList field is not configured with the corresponding second element indication information, and the fourth element corresponds to the information indicated by the dl-PRS-ReferenceInfo field.

[0262] In one possible implementation, only some elements in the nr-DL-TDOA-MeasList field are configured with corresponding second element indication information. That is, the aforementioned third element is a part of the elements in the nr-DL-TDOA-MeasList field. Then, the other elements in the nr-DL-TDOA-MeasList field other than the third element are denoted as the fourth element, and the fourth element corresponds to the information indicated by the dl-PRS-ReferenceInfo field.

[0263] Optionally, the second element indication information is configured in NR-DL-TDOA-MeasElement.

[0264] Understandably, in version 1.3.4, the existing LPP protocol and procedures reuse the DL-PRS-ReferenceInfo and NR-DL-TDOA-MeasList signaling, and reuse the two existing fields: the dl-PRS-ReferenceInfo field and the nr-DL-TDOA-MeasList field. At the same time, one or more eighth information fields are added. The nr-DL-TDOA-MeasList field and a part of the dl-PRS-ReferenceInfo field correspond to a set of positioning measurement results, one eighth information field and a part of the dl-PRS-ReferenceInfo field correspond to a set of positioning measurement results, or multiple eighth information fields and a part of the dl-PRS-ReferenceInfo field correspond to multiple sets of positioning measurement results. The standardization workload is small, and when the value of X is small, the protocol structure is simple.

[0265] For example, if the maximum value of X is 2, based on subsequent evolution versions, 1.3.4 is described in the protocol standard as follows:

[0266]

[0267] The case where X takes a larger value can be derived from the example above, and will not be elaborated here.

[0268] Based on the example above, we can extend this further: the eighth information field (dl-PRS-ReferenceInfo2) does not exist; there is only the second element, indication information (firstInfo). If the value of firstInfo is different, the corresponding positioning measurement results belong to different groups; if the value of firstInfo is the same, the corresponding positioning measurement results belong to the same group.

[0269] Please refer to Figure 6 The diagram illustrates a flowchart of a positioning measurement result reporting method provided in another embodiment of this application. This method can be applied to... Figure 1 In the network architecture shown, the method may include the following steps (602-608):

[0270] Step 602: The network device sends first configuration information to the terminal device. The first configuration information is used to indicate the configuration of the downlink positioning signal.

[0271] Optionally, the first configuration information may be carried in the NR-Downlink-Time Difference of Arrival-ProvideAssistanceData (NR-DL-TDOA-ProvideAssistanceData) element. The NR-DL-TDOA-ProvideAssistanceData element is a type of location information element.

[0272] Optionally, the downlink positioning signal includes: PRS. As communication standards evolve, network devices may also configure other types of downlink positioning signals for terminal devices, and this application does not impose any restrictions on this.

[0273] Step 604: The terminal device receives the first configuration information sent by the network device.

[0274] The first configuration information is used to indicate the configuration of the downlink positioning signal.

[0275] Optionally, the downlink positioning signal includes downlink positioning signals from Y sets, where Y is a positive integer. Optionally, the transmission timing of the TRP corresponding to the downlink positioning signal in each set is the same.

[0276] In one possible implementation, Y equals X, and X sets of positioning measurement results correspond one-to-one with Y sets. That is, each set of positioning measurement results in the X sets represents a downlink positioning signal from one of the Y sets. This implementation can accommodate situations where there is only asynchrony between different TRPs.

[0277] In another possible implementation, Y is less than X, and at least one set of positioning measurement results from the X sets corresponds to one of the Y sets. Each set of positioning measurement results from the X sets corresponds to only one of the Y sets. This implementation can accommodate situations where different TRPs are asynchronous, and the timing of the receiving end on the terminal device side is different, both of which exist simultaneously.

[0278] Step 606: Using the first information, the terminal device sends X sets of positioning measurement results to the network device, where X is a positive integer not less than 2.

[0279] The implementation method for this step can be found in step 502 above, and will not be repeated here.

[0280] Step 608: Through the first information, the network device receives X sets of positioning measurement results sent by the terminal device.

[0281] The implementation method for this step can be found in step 504 above, and will not be repeated here.

[0282] In summary, the technical solution provided in this embodiment addresses the issue of asynchronous transmission between different TRPs when configuring downlink positioning signals for terminal devices on the network side. This means that the transmission timing of downlink positioning signals by different TRPs is different. In such cases, the downlink positioning signals with Y different transmission timings can be divided into Y sets, with each set corresponding to a set of positioning measurement results. This avoids errors in positioning measurement results caused by different transmission timings and helps improve positioning accuracy.

[0283] Furthermore, in cases where both TRP transmission timing and terminal device receiving timing differ simultaneously, reporting the corresponding sets of positioning measurement results can avoid errors caused by these two situations and help improve positioning accuracy.

[0284] Please refer to Figure 7 The diagram illustrates a flowchart of a positioning measurement result reporting method provided in another embodiment of this application. This method can be applied to... Figure 1 In the network architecture shown, the method may include the following steps (702-708):

[0285] Step 702: The network device sends second configuration information to the terminal device. The second configuration information is used to instruct the terminal device to support reporting at least two sets of positioning measurement results.

[0286] Optionally, the second configuration information is carried in the NR-DL-TDOA-ProvideAssistanceData information cell.

[0287] Optionally, the second configuration information is carried in the ProvideAssistanceData element. The ProvideAssistanceData element is a type of location information element.

[0288] Optionally, the second configuration information and the first configuration information are carried in the same information cell. The first configuration information is sent by the network device and is used to indicate the configuration of the downlink positioning signal. For example, both the first and second configuration information are carried in the NR-DL-TDOA-ProvideAssistanceData information cell.

[0289] Step 704: The terminal device receives the second configuration information sent by the network device.

[0290] The second configuration information is used to instruct the terminal device to support reporting at least two sets of positioning measurement results.

[0291] Step 706: Using the first information, the terminal device sends X sets of positioning measurement results to the network device, where X is a positive integer not less than 2.

[0292] The implementation method for this step can be found in step 502 above, and will not be repeated here.

[0293] Step 708: Through the first information, the network device receives X sets of positioning measurement results sent by the terminal device.

[0294] The implementation method for this step can be found in step 504 above, and will not be repeated here.

[0295] In summary, the technical solution provided in this embodiment allows the network device to send second configuration information to the terminal device, instructing the terminal device to support reporting at least two sets of positioning measurement results, which facilitates the network device to flexibly instruct the terminal device on the reporting method of positioning measurement results.

[0296] Please refer to Figure 8 The diagram illustrates a flowchart of a positioning measurement result reporting method provided in another embodiment of this application. This method can be applied to... Figure 1 In the network architecture shown, the method may include the following steps (802-808):

[0297] Step 802: Using the second information, the terminal device reports the first terminal capability to the network device. The first terminal capability indicates that the terminal device supports reporting at least two sets of positioning measurement results.

[0298] Optionally, the first terminal capability includes the maximum number of sets of positioning measurement results that the terminal device supports sending. For example, the maximum number of sets is 2. For example, the maximum number of sets is 3.

[0299] Optionally, the second information belongs to the terminal capability reporting signaling.

[0300] Step 804: The network device receives the first terminal capability reported by the terminal device through the second information.

[0301] The first terminal capability indicates that the terminal device supports reporting at least two sets of positioning measurement results.

[0302] In one possible implementation, the second information is information transmitted via LPP.

[0303] Accordingly, step 802 is replaced by: transmitting second information via LPP, and the terminal device reporting the first terminal capability to the network device; step 804 is replaced by: transmitting second information via LPP, and the network device receiving the first terminal capability reported by the terminal device.

[0304] Optionally, in this approach, the network device is a location server. It is understood that this approach reuses existing protocol procedures, with the terminal device reporting its capabilities to the location server via LPP. This approach reduces the workload of standardizing protocols.

[0305] Optionally, the second information is transmitted via the NR-Downlink-Time Difference of Arrival-ProvideCapabilities (NR-DL-TDOA-ProvideCapabilities) information element. The NR-DL-TDOA-ProvideCapabilities information element is a type of location information element.

[0306] Optionally, the second information is transmitted via the NR-DL-TDOA-MeasurementCapability (NR-DL-TDOA) information element. The NR-DL-TDOA-MeasurementCapability information element is a type of location information element.

[0307] In another possible implementation, the second information is transmitted via RRC signaling.

[0308] Accordingly, step 802 is replaced by: the terminal device reporting the first terminal capability to the network device via RRC signaling; step 804 is replaced by: the network device receiving the first terminal capability reported by the terminal device via RRC signaling.

[0309] Optionally, in this method, the network device serves as the serving base station for the terminal device. It is understood that in method 2, the terminal device reports its capabilities to the serving base station via RRC signaling, which can reduce latency caused by information transmission or processing.

[0310] It is understood that, in addition to RRC signaling, terminal devices may also use other types of signaling to report first terminal capabilities to network devices. Such signaling may be other existing types of signaling or newly introduced signaling compared to existing versions of standard protocols. This application does not impose any restrictions on this.

[0311] Step 806: Using the first information, the terminal device sends X sets of positioning measurement results to the network device, where X is a positive integer not less than 2.

[0312] The implementation method for this step can be found in step 502 above, and will not be repeated here.

[0313] Step 808: Through the first information, the network device receives X sets of positioning measurement results sent by the terminal device.

[0314] The implementation method for this step can be found in step 504 above, and will not be repeated here.

[0315] In summary, the technical solution provided in this embodiment allows the terminal device to report its first terminal capability when it supports reporting at least two sets of positioning measurement results, i.e., when the terminal device is a high-capability terminal device. This facilitates higher-precision positioning for the high-capability terminal device.

[0316] In an illustrative embodiment, the first terminal capability can be reported according to one of the following options:

[0317] • The first terminal capability is reported independently according to frequency band (band), that is, it is reported in a per band manner.

[0318] In other words, different frequency bands can independently report the corresponding first terminal capabilities.

[0319] Understandably, independently reporting the corresponding first terminal capabilities according to different frequency bands allows terminal devices to achieve greater freedom. For example, a terminal device can support the positioning measurement result reporting method provided in this application on one or more frequency bands, while not supporting this method on other frequency bands, thereby allowing more terminal devices to support this method.

[0320] • The capabilities of the first terminal are reported independently according to band combination, that is, reported in the form of perband combination.

[0321] In other words, different frequency band combinations can independently report the corresponding first terminal capabilities.

[0322] It is understandable that independently reporting the corresponding first terminal capabilities according to different frequency band combinations allows terminal devices to achieve greater freedom. For example, a terminal device can support the positioning measurement result reporting method provided in this application on one or more frequency band combinations, while not supporting this method on other frequency band combinations, thereby allowing more terminal devices to support this method.

[0323] • The first terminal capability is reported independently for each frequency band in the frequency band combination, that is, it is reported in a per band per band combination manner.

[0324] In other words, the frequency bands in different frequency band combinations can independently report the corresponding first terminal capabilities.

[0325] It is understandable that allowing the independent reporting of the corresponding first terminal capability by the frequency bands in different frequency band combinations allows terminal devices to achieve greater flexibility. For example, a terminal device may not support the positioning measurement result reporting method provided in this application under a certain frequency band combination, but it may support this method under certain frequency bands in another frequency band combination, thereby allowing more terminal devices to support this method.

[0326] • The first terminal capability is reported according to the frequency range.

[0327] In other words, different frequency ranges can independently report the corresponding first terminal capabilities.

[0328] It is understandable that independently reporting the corresponding first terminal capabilities according to different frequency ranges allows terminal devices to achieve greater freedom. For example, a terminal device may not support the positioning measurement result reporting method provided in this application at low frequency (FR1), but it may support this method at high frequency (FR2), thereby allowing more terminal devices to support this method.

[0329] Here, FR1 refers to frequency range 1, for example, including 410MHz–7125MHz. FR2 refers to frequency range 2, for example, including 24250MHz–52600MHz. It is understood that with the evolution of communication standards, the above frequency ranges can cover more frequency bands, such as FR2 further extending to higher frequencies, and this application embodiment does not impose any limitations on this.

[0330] • The first terminal capability is for reporting in frequency range 2.

[0331] That is, the terminal device can report the corresponding first terminal capability in frequency range 2.

[0332] Understandably, reporting the capabilities of the first terminal only for frequency range 2 simplifies the capabilities of low-frequency terminals and only supports the differentiation of capabilities for high-frequency terminals.

[0333] It should be noted that the above method embodiments can be implemented individually or in combination, and this application does not impose any restrictions on this.

[0334] It should be noted that, in the above method embodiments, the technical solution of this application is mainly described from the perspective of the interaction between the terminal device and the network device.
