[0028] The following description, in conjunction with the accompanying drawings, details the method and device for sending or receiving measurement reports of positioning reference signals provided in this application, through some embodiments and application scenarios.

[0029] like Figure 2As shown, this application embodiment provides a measurement report transmission method 200 for a positioning reference signal. This method can be executed by a terminal; in other words, it can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0030] S202: The terminal performs measurements on-demand PRS to generate a measurement report.

[0031] In this embodiment, the terminal can measure on-demand PRS according to an initial on-demand PRS configuration, which may be initially determined by the Location Management Function (LMF) and / or gNB.

[0032] In one example, before the terminal measures on-demand PRS to generate a measurement report, the method further includes: the terminal receiving on-demand PRS measurement configuration information; wherein, the terminal measuring on-demand PRS to generate a measurement report includes: the terminal measuring on-demand PRS according to the on-demand PRS measurement configuration information to generate a measurement report. In this example, the on-demand PRS measurement configuration information may indicate the measurement parameters that the terminal needs to measure, the measurement period, the type of measurement result, etc.

[0033] Optionally, the on-demand PRS measurement configuration information can come from LMF or TRP. In a specific example, the on-demand PRS measurement configuration information is generated by LMF.

[0034] Optionally, the on-demand PRS measurement configuration information may be included in the RequestLocationInformation message or in the ProvideAssistanceData message.

[0035] In another example, the terminal can also perform on-demand PRS measurements according to predefined rules to generate a measurement report. These predefined rules can be protocol-defined. In this example, the protocol can predefine the measurement parameters the terminal needs to measure, the measurement cycle, the type of measurement results, and so on.

[0036] Optionally, before S202, the following step may be included: the terminal sends a first indication, the first indication being used to indicate that the terminal supports generating the measurement report. It is understood that this embodiment will not be executed for terminals that do not support generating the measurement report.

[0037] S204: The terminal sends the measurement report; wherein the measurement report is used to perform on-demand PRS reconfiguration on the terminal.

[0038] The on-demand PRS reconfiguration of the terminal mentioned in this embodiment can also be referred to as optimizing the on-demand PRS configuration of the terminal.

[0039] In this embodiment, the network-side device can perform on-demand PRS reconfiguration on the terminal based on the measurement report, which may specifically include at least one of the following 1) to 10):

[0040] 1) Only configure PRS (resources) whose Reference Signal Receiving Power (RSRP) measurement value is higher than certain conditions.

[0041] 2) Delete existing PRS with RSRP measurements below certain conditions. These existing PRS can be the initial on-demand PRS configurations set by network-side devices for terminals prior to S202.

[0042] 3) Only configure PRS with a Time Difference of Arrival (TDoA) uncertainty below a certain condition.

[0043] 4) Delete the original PRS where the TDoA uncertainty is higher than a certain condition.

[0044] 5) Only configure TRPs with a Time of Arrival (ToA) uncertainty below a certain condition.

[0045] 6) Delete the original TRPs where the ToA uncertainty is higher than a certain condition.

[0046] 7) Only configure PRS with a line of sight (LOS) certainty higher than certain conditions.

[0047] 8) Delete PRS whose LOS certainty is lower than a certain condition.

[0048] 9) Only configure TRPs with LOS certainty higher than certain conditions.

[0049] 10) Delete TRPs whose LOS certainty is below a certain condition.

[0050] The positioning reference signal measurement report transmission method provided in this application embodiment involves a terminal measuring the on-demand PRS to generate and transmit a measurement report. This allows the network-side device to reconfigure the terminal's on-demand PRS based on the measurement report. This application embodiment fully considers the terminal's usage of PRS configuration, enabling the configuration of a more reasonable PRS for the terminal and facilitating improved communication performance.

[0051] Optionally, in S202, the terminal can measure on-demand PRS according to on-demand PRS measurement configuration information to generate a measurement report. This on-demand PRS measurement configuration information can be included in a RequestLocationInformation message, and can include at least one of the following 1) to 3):

[0052] 1) Measurement parameter threshold, wherein the measurement parameter threshold is used by the terminal to report the PRS resource identifier (ID), PRS resource ID pair or Transmission and Reception Point (TRP) ID in the measurement report, and the measurement value of the measurement parameter corresponding to the PRS resource ID, PRS resource ID pair or TRP ID is within the range corresponding to the measurement parameter threshold.

[0053] The above measurement parameters may include one of the following: PRS RSRP, PRS to TDoA, TRP toA, PRS LOS determination, and TRP LOS determination.

[0054] The threshold for this measurement parameter is, for example, -100, and the range corresponding to this threshold can be, for example, higher than -100.

[0055] 2) The number of resources K for the measurement parameters, wherein the number of resources K for the measurement parameters is used by the terminal to determine the maximum number of PRS resource IDs, PRS resource ID pairs or TRP IDs corresponding to the measurement values ​​of the measurement parameters to be reported, wherein K is a positive integer.

[0056] 3) Measurement parameter threshold sequence, the measurement parameter threshold sequence includes multiple measurement parameter thresholds that constitute an interval distribution, the multiple measurement parameter thresholds are used by the terminal to report PRS resource ID, PRS resource ID pair or TRP ID in the measurement report, the measurement value of the measurement parameter corresponding to the PRS resource ID, PRS resource ID pair or TRP ID is within the interval range corresponding to the multiple measurement parameter thresholds.

[0057] The measurement parameter threshold sequence includes, for example, three measurement parameter thresholds: -100, -90, and -80. These three thresholds can form four intervals: (-∞, -100], (-100, -90], (-90, -80], and (-80, +∞). In this way, the terminal can report the PRS resource ID, PRS resource ID pair, or TRP ID for each interval, representing the measured value of the measurement parameter within that interval.

[0058] Optionally, this embodiment may further include the following steps: if the number of PRS resource IDs, PRS resource ID pairs, or TRP IDs within the range corresponding to the measurement parameter threshold is greater than K, then the terminal performs at least one of the following:

[0059] a) If the on-demand PRS measurement configuration information does not include indication information for indicating the type of measurement result, randomly report K PRS resource IDs, PRS resource ID pairs, or TRP IDs.

[0060] b) If the on-demand PRS measurement configuration information includes indication information for indicating the type of measurement result, and the type of measurement result is the minimum value of the measurement result, report the K PRS resource IDs, PRS resource ID pairs, or TRP IDs with the smallest measured values ​​of the measurement parameters.

[0061] c) When the on-demand PRS measurement configuration information includes indication information for indicating the type of measurement result, and the type of the measurement result is the maximum value of the measurement result, report the K largest PRS resource IDs, PRS resource ID pairs, or TRP IDs of the measurement parameters.

[0062] The types of measurement results mentioned in the examples above include at least one of the following: the maximum value of the measurement result, the minimum value of the measurement result, the average value of the measurement result, and the interval distribution of the measurement result. It should be noted that the maximum value mentioned here can be the M largest values, and the minimum value mentioned here can be the N smallest values, where M and N are positive integers, i.e., greater than 1.

[0063] For example, in this embodiment, if the number of PRS resources whose PRS RSRP measurement values ​​are within the range corresponding to the PRS RSRP threshold exceeds K, the terminal may perform at least one of the following: a) If there is no indication information for indicating the type of measurement result, randomly report K PRS resource IDs; b) If the type indication of the measurement result is the minimum value, report the K PRS resource IDs with the smallest RSRP measurement value, for example, sort the RSRP measurement values ​​from smallest to largest and report the K PRS resource IDs with the smallest measurement values; c) If the type indication of the measurement result is the maximum value, report the K PRS resource IDs with the largest RSRP measurement value, for example, sort the RSRP measurement values ​​from largest to smallest and report the K PRS resource IDs with the largest measurement values.

[0064] For example, in this embodiment, if the number of PRS resource pairs whose PRS TDoA uncertainty measurements fall within the range corresponding to the PRS TDoA uncertainty threshold exceeds K, the terminal may perform at least one of the following: a) If there is no indication information for indicating the type of measurement result, randomly report K PRS resource ID pairs; b) If the type indication of the measurement result is the minimum value, report the K PRS resource ID pairs with the minimum PRS TDoA uncertainty measurement value; c) If the type indication of the measurement result is the maximum value, report the K PRS resource ID pairs with the maximum PRS TDoA uncertainty measurement value.

[0065] For example, in this embodiment, if the number of TRPs whose TRP ToA uncertainty measurement values ​​are within the range corresponding to the TRP ToA uncertainty threshold exceeds K, the terminal may perform at least one of the following: a) If there is no indication information for indicating the type of measurement result, randomly report K TRP IDs; b) If the type indication of the measurement result is the minimum value, report the K TRP IDs with the smallest TRP ToA uncertainty measurement values; c) If the type indication of the measurement result is the maximum value, report the K TRP IDs with the largest TRP ToA uncertainty measurement values.

[0066] For example, in this embodiment, if the number of PRS resources whose PRS LOS certainty measurement values ​​fall within the range corresponding to the PRS LOS certainty threshold exceeds K, the terminal may perform at least one of the following: a) If there is no indication information for indicating the type of the measurement result, randomly report K PRS resource IDs; b) If the type indication of the measurement result is the minimum value, report the K PRS resource IDs with the minimum PRS LOS certainty measurement value; c) If the type indication of the measurement result is the maximum value, report the K PRS resource IDs with the maximum PRS LOS certainty measurement value.

[0067] For example, in this embodiment, if the number of TRPs whose TRP LOS certainty measurement value falls within the range corresponding to the TRP LOS certainty threshold exceeds K, the terminal may perform at least one of the following: a) If there is no indication information for indicating the type of measurement result, randomly report K TRP IDs; b) If the type indication of the measurement result is the minimum value, report the K TRP IDs with the smallest TRP LOS certainty measurement value; c) If the type indication of the measurement result is the maximum value, report the K TRP IDs with the largest TRP LOS certainty measurement value.

[0119] Optionally, the method further includes: when the terminal receives the on-demand PRS response message, the terminal starts a second timer; wherein, before the second timer expires, the terminal does not send the on-demand PRS request message again, or, the terminal does not send the on-demand PRS request message corresponding to the on-demand PRS configuration again, the on-demand PRS configuration corresponding to the second timer, the on-demand PRS configuration being used to generate the measurement report.

[0120] The above embodiments, by introducing a first timer or a second timer, can avoid the terminal frequently requesting PRS configuration updates after receiving the initial on-demand PRS configuration, which helps to reduce signaling overhead.

[0121] To explain in detail the method for sending or receiving measurement reports of positioning reference signals provided in the embodiments of this application, the following will describe it in conjunction with several specific embodiments.

[0122] Example 1

[0123] In this embodiment, the UE generates and reports an on-demand PRS measurement report, which includes the following steps:

[0124] Step 1: The network requests UE capabilities from the UE. Upon receiving the request, the UE reports its capabilities, including whether it supports generating on-demand PRS measurement reports. In this embodiment, the UE supports generating on-demand PRS measurement reports.

[0125] Step 2: The LMF provides the UE with available on-demand PRS configurations via LTE Positioning Protocol (LPP) dedicated signaling messages or via Positioning System Information (Pos SI) broadcast messages. These configurations contain a list of on-demand PRS configurations.

[0126] Step 3: After the network obtains the UE's capabilities, it can optionally issue an on-demand PRS report configuration (corresponding to the on-demand PRS measurement configuration information in the previous embodiment) to the UE based on network optimization requirements and UE capabilities. This on-demand PRS report configuration is associated with the on-demand PRS configuration.

[0127] The on-demand PRS report configuration can include a function indicator that instructs the measurement to be used to generate an on-demand PRS measurement report.

[0128] The on-demand PRS report configuration may include measurement indications, which instruct the UE to measure corresponding measurement parameters, such as: PRS RSRP threshold, number of PRS resources, PRS TDoA uncertainty threshold, number of PRS resource pairs, TRP ToA uncertainty threshold, number of TRP ToA, PRS LOS certainty threshold, number of PRS LOS certainties, TRP LOS certainty threshold, and number of TRP LOS certainties. For details, please refer to the description of the on-demand PRS measurement configuration information in the previous embodiment.

[0129] Step 4: The UE sends an on-demand PRS configuration request to the LMF via an LPP message (corresponding to the on-demand PRS request message in the previous embodiment).

[0130] Step 5: The LMF sends an on-demand PRS configuration response to the UE (corresponding to the on-demand PRS response message in the previous embodiment), indicating whether the on-demand PRS request has been satisfied. The LMF may also include the on-demand PRS report configuration described in Step 3 in this step.

[0131] Step 6: If the on-demand PRS request is successful, the UE performs measurements according to the LMF request, generates an on-demand PRS measurement report based on the measurement results, and reports it by providing location information or by introducing a new message.

[0132] Optionally, the measurement quantity of the UE response may include one of the following: PRS RSRP, PRS TDoA uncertainty, TRPToA uncertainty, PRS LOS certainty, and TRP LOS certainty.

[0133] Step 7: After receiving the on-demand PRS measurement report, the network optimizes the on-demand PRS configuration based on the on-demand PRS measurement report (i.e., reconfigures the on-demand PRS configuration).

[0134] Example 2

[0135] This embodiment mainly introduces timers related to on-demand PRS requests, and includes the following steps:

[0136] Step 1: The LMF obtains the configuration information of the available PRS by exchanging New Radio Positioning Additional Protocol (NRPPa) messages with multiple TRPs.

[0137] Step 2: The LMF provides the UE with available on-demand PRS configurations via LPP dedicated signaling messages or via Pos SI broadcast messages. The on-demand PRS configuration contains a list of PRS configurations, and each PRS configuration contains a Timer 1 or is associated with a Timer 1.

[0138] Step 3: The UE sends an on-demand PRS configuration request to the LMF via an LPP message and starts timer 1.

[0139] Step 4: The LMF decides to send the on-demand DL-PRS configuration request to the gNB.

[0140] Step 5: The LMF sends an on-demand PRS configuration request to the relevant TRP via an NRPPa message.

[0141] Step 6: The relevant TRP sends an on-demand PRS configuration response to the LMF via NRPPa message. This response can be either successful or failed.

[0142] Step 7: The LMF provides the UE with an on-demand PRS configuration response via an LPP dedicated signaling message or a Pos SI broadcast message, which includes a timer 2.

[0143] Step 8: After the UE receives the on-demand PRS configuration response, it starts timer 2.

[0144] Before Timer 1 or Timer 2 expires, the UE cannot request on-demand PRS configuration again, or the UE cannot request the on-demand PRS configuration corresponding to the timer again.

[0145] After Timer 1 and Timer 2 expire, the UE can request on-demand PRS configuration again, or the UE can request the on-demand PRS configuration corresponding to the timer again.
