As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0057] The positioning processing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0058] like Figure 2 As shown, the positioning processing method of the embodiment of the present application is applied to a terminal, including:

[0059] Step 201: receiving first configuration information sent by a network side device; wherein the first configuration information is used to indicate the configuration of a target reference signal for positioning measurement; and the target reference signal includes at least one of the following:

[0060] Positioning reference signal PRS;

[0061] Channel state information reference signal CSI-RS;

[0062] Tracking reference signal TRS;

[0063] Synchronization signal block reference signal SSB-RS.

[0064] In this step, by receiving the first configuration information sent by the network side device, the configuration of the network side device for at least one target reference signal of PRS, CSI-RS, TRS and SSB-RS is understood, so as to flexibly measure multiple types of reference signals.

[0065] Step 202: Determine a target reference signal and first measurement information of the target reference signal according to the first configuration information.

[0066] In this step, after the first configuration information is received in step 201, the target reference signal is determined by the first configuration information, and the first measurement information of the target reference signal can also be determined to complete the positioning measurement.

[0067] Through steps 201-202, the method of the embodiment of the present application first receives the first configuration information sent by the network side device for indicating the configuration of the target reference signal for positioning measurement, determines the target reference signal corresponding to the positioning measurement, and understands the relevant configuration of the target reference signal, so as to determine the first measurement information of the target reference signal. Since the target reference signal includes at least one of PRS, CSI-RS, TRS and SSB-RS, the positioning measurement can be implemented more flexibly, avoiding excessive overhead and high latency caused by only measuring through PRS.

[0068] Optionally, the first configuration information includes at least one of the following:

[0069] PRS configuration information of the reference cell;

[0070] PRS configuration information of neighboring cells;

[0071] CSI-RS configuration information of the reference cell;

[0072] CSI-RS configuration information of neighboring cells;

[0073] Reference cell's TRS configuration information;

[0074] TRS configuration information of neighboring cells;

[0075] SSB-RS configuration information of the reference cell;

[0076] SSB-RS configuration information of neighboring cells.

[0077] The reference cell is predefined or configured, and may be a serving cell of the terminal or a non-serving cell. The neighboring cell is a neighboring cell of the serving cell of the corresponding terminal. By receiving the first configuration information including at least one of the above configuration information, the terminal can determine the target reference signal of the current positioning measurement to complete the targeted positioning measurement.

[0078] Optionally, the first measurement information includes at least one of the following:

[0079] Reference signal received power RSRP;

[0080] Reference signal time difference RSTD;

[0081] Time of arrival TOA;

[0082] Time difference between sending and receiving;

[0083] Receive beam number.

[0084] Thus, for the target reference signal, the positioning measurement needs to measure at least one of the RSRP, RSTD, TOA, Rx-Tx time difference, and receiving beam number of the target reference signal. For example, if the target reference signal is CSI-RS, then at least one of the RSRP, RSTD, TOA, Rx-Tx time difference, and receiving beam number of the CSI-RS is obtained in step 203.

[0085] In addition, in this embodiment, optionally, after step 202, the following steps are further included:

[0086] Reporting the first measurement information;

[0087] The first measurement information is reported via location information, and the location information also indicates a type of the first measurement information.

[0088] Here, the type of the first measurement information refers to the type of the target reference signal corresponding to when the first measurement information is obtained, that is, which type of target reference signal is used to measure the first measurement information. For example, the target reference signal is CSI-RS, and the type of the first measurement information is CSI-RS. Among them, if the first measurement information is obtained by measuring a single target reference signal, the first measurement information of the target reference signal and its type are reported; if it is obtained by measuring multiple target reference signals, the UE can report the first measurement information and its type that it considers to be the best, such as the measurement information corresponding to the target reference signal with a larger bandwidth, or it can report several first measurement information and their types that it considers to be better, or it can report all the first measurement information and their types.

[0089] For example, if the UE measures a PRS with a bandwidth of 200M, a CSI-RS with a bandwidth of 200M, and an SSB with a bandwidth of 20M, the UE may report the first measurement information of the PRS with a bandwidth of 200M, or the UE may preferably report the first measurement information of the PRS with a bandwidth of 200M and the CSI-RS with a bandwidth of 200M.

[0090] There are two ways to indicate the type of the first measurement information in the location information: way 1, adding a bit string for indication; way 2, adding new measurement information in the measurement element for indication.

[0091] Take the Provide Location Information as an example, according to the first method, add a bit string for indication, and the modified Provide Location Information structure is as follows:

[0092]

[0093]

[0094] According to the second method, new measurement information is added to the measurement element for indication. The specific structure of the measurement element Meas Element in the modified ProvideLocation Information structure is as follows:

[0095]

[0096] In this embodiment, optionally, before step 203, the method further includes:

[0097] Acquire second measurement information of the target reference signal;

[0098] Step 203 includes:

[0099] Report the first measurement information according to the second measurement information and the received second configuration information sent by the network side device.

[0100] In this way, after the acquisition of the first measurement information is completed, the second measurement information of the target reference signal is acquired, and the reporting behavior is determined by the second measurement information and the received second configuration information sent by the network side device to realize the reporting of the first measurement information.

[0101] Optionally, the second measurement information includes at least one of the following:

[0102] The relative measurement value of RSRP between the current measurement and the last measurement;

[0103] The relative measurement value of RSTD between the current measurement and the previous measurement;

[0104] The relative measurement value of TOA between the current measurement and the previous measurement;

[0105] The relative transmit / receive time difference measurement value between the current measurement and the last measurement;

[0106] Whether the receive beam sequence of the current measurement has changed from that of the previous measurement.

[0107] Here, the second measurement information can reflect the change of the positioning measurement amount, so that the reporting behavior can be determined through the second measurement information to achieve effective reporting, thereby reducing resource overhead.

[0108] The second measurement information is obtained based on the first measurement information:

[0109] The relative measurement value of the RSRP obtained by the current measurement and the last measurement can be determined by the difference between the RSRP obtained by the current measurement and the RSRP obtained by the last measurement in the first measurement information;

[0110] The relative measurement value of the RSTD obtained by the current measurement and the previous measurement can be determined by the difference between the RSTD obtained by the current measurement and the RSTD obtained by the previous measurement in the first measurement information;

[0111] The relative measurement value of the TOA obtained by the current measurement and the previous measurement can be determined by the difference between the TOA obtained by the current measurement and the TOA obtained by the previous measurement in the first measurement information;

[0112] The relative measurement value of the Rx-Tx time difference obtained by the current measurement and the last measurement can be determined by the difference between the Rx-Tx time difference obtained by the current measurement and the Rx-Tx timedifference obtained by the last measurement in the first measurement information;

[0113] Whether the receiving beam sequence between the current measurement and the last measurement has changed can be determined by comparing the receiving beam sequence obtained by the current measurement with the receiving beam sequence obtained by the last measurement in the first measurement information to see whether they are the same.

[0114] Considering that in this embodiment, the type of the target reference signal can be one or more, therefore, optionally, the current measurement in the second measurement information and the previous measurement correspond to the same type of target reference signal, or the current measurement in the second measurement information and the previous measurement correspond to different types of target reference signals.

[0115] For example, the target reference signals are CSI-RS and TRS, and the RSRP currently measured corresponds to the CSI-RS. If the RSRP measured on the previous side also corresponds to the CSI-RS, the relative measurement value of RSRP in the second measurement information corresponds to the same type of target reference signal; if the RSRP measured on the previous side corresponds to TRS, the relative measurement value of RSRP in the second measurement information corresponds to different types of target reference signals.

[0116] In this embodiment, optionally, the second configuration information includes at least one of the following:

[0117] RSRP relative measurement threshold;

[0118] RSTD relative measurement threshold;

[0119] TOA relative measurement threshold;

[0120] Relative measurement threshold of the sending and receiving time difference;

[0121] The receiving beam number is changed;

[0122] Reporting period threshold.

[0123] In this way, the terminal can determine the specific reporting behavior based on the content of the second configuration information notified by the network side device to the terminal. Of course, the network side device can send the second configuration information at the same time as sending the first configuration information, or before or after sending the first configuration information.

[0124] Specifically, the second configuration information is sent by the message Triggered Reporting Criteria. For example, the structure of Triggered Reporting Criteria is as follows:

[0125]

[0126] Optionally, reporting the first measurement information according to the second measurement information and the received second configuration information sent by the network side device includes:

[0127] If the terminal adopts triggered reporting, then when the second measurement information meets the first preset condition corresponding to the second configuration information, reporting the current first measurement information;

[0128] If the terminal adopts periodic reporting, then when the second measurement information meets the second preset condition corresponding to the second configuration information, the current first measurement information is reported in the next reporting period;

[0129] If the terminal adopts periodic reporting, then when the second measurement information does not meet the second preset condition corresponding to the second configuration information, and the time interval between the next reporting cycle and the last reporting is greater than the reporting cycle threshold, the current first measurement information is reported in the next reporting cycle.

[0130] Among them, the first preset condition and the second preset condition may be the same or different. In addition, the first preset condition and the second preset condition may be predefined or configured, or may be set using the content of the second configuration information. For example, the first preset condition and the second preset condition both use the RSRP relative measurement threshold in the second configuration information. If the terminal uses trigger reporting, the relative measurement value of RSRP obtained from the current measurement and the last measurement in the second measurement information is greater than or equal to the RSRP relative measurement threshold, that is, the first preset condition is met, and the current first measurement information is reported; if the terminal uses periodic reporting, the relative measurement value of RSRP obtained from the current measurement and the last measurement in the second measurement information is greater than or equal to the RSRP relative measurement threshold, that is, the second preset condition is met, and the current first measurement information is reported; if the terminal uses periodic reporting, the relative measurement value of RSRP obtained from the current measurement and the last measurement in the second measurement information is less than the RSRP relative measurement threshold, that is, the second preset condition is not met, but the time interval between the next reporting cycle and the last reporting is greater than the reporting cycle threshold, and the current first measurement information is reported in the next reporting cycle. Of course, if the first preset condition or the second preset condition adopts the change of the receiving beam number in the second configuration information, the receiving beam number between the current measurement and the previous measurement is changed, that is, the first preset condition or the second preset condition is met; the receiving beam number between the current measurement and the previous measurement is not changed, that is, the first preset condition or the second preset condition is not met.

[0131] Among them, trigger reporting and periodic reporting are reporting methods for the terminal to perform positioning measurement. In addition to the pre-agreed reporting method, the reporting method supported by the terminal can also be understood in combination with the positioning method used for positioning measurement. Therefore, in this embodiment, optionally, before reporting the first measurement information, it also includes:

[0132] Receive fourth configuration information sent by the network side device; wherein the fourth configuration information is used to configure a reporting method of each positioning method.

[0133] In this way, after receiving the fourth configuration information sent by the network-side device, the terminal learns the reporting method of each positioning method from the fourth configuration information, and then performs reporting.

[0134] The fourth configuration information is implemented by Common IEs Request Location Information. Specifically, the structure of Common IEs Request Location Information is as follows:

[0135]

[0136]

[0137] In this embodiment, in the structure of Common IEs Request Location Information, it can be indicated whether the positioning method supports trigger reporting, such as adding

[0138]

[0139] In this embodiment, if the bandwidth of the target reference signal is small, the accuracy of the positioning measurement may be low. Therefore, optionally, after reporting the first measurement information, the method further includes:

[0140] Sending second request information; wherein the second request information is used to request third configuration information, and the third configuration information includes PRS configuration information.

[0141] The terminal further requests the network side device for PRS configuration information, so that it can subsequently implement more effective positioning measurement for PRS based on the received PRS configuration information sent by the network side device to meet higher precision positioning requirements.

[0142] In addition, in this embodiment, optionally, before step 201, the following is further included:

[0143] Sending first request information; wherein the first request information is used to request the type of the target reference signal; and / or,

[0144] The first request information is used to request first configuration information.

[0145] The terminal can request the network side device by sending the first request information in combination with its own capabilities. The first request information can be used to request the type of the target reference signal, that is, the first configuration information sent by the network side device based on the first request information is the configuration information of the target reference signal requested by the first request information; the first request information can also be used to request the first configuration information, that is, the network side device sends the corresponding first configuration information based on the first request information. In this way, it is possible to facilitate better positioning measurement.

[0146] The first request information is implemented by requesting auxiliary data RequestAssistanceData. Specifically, a bit string adType is used in RequestAssistanceData to indicate the type of the requested target reference signal, that is, which type of reference signal is requested to measure the first measurement information. For example, BIT STRING{dl-prs(0), CSI-RS(1), TRS(2), SSB(3)}(SIZE(1..8)), where the number of bits in the corresponding position of each reference signal is 0, indicating that the reference signal of this type is not used, and 1 indicates that the reference signal of this type is used.

[0147] Optionally, step 202 includes:

[0148] determining a target reference signal and first measurement information of the target reference signal according to the positioning capability information of the terminal and the first configuration information; or

[0149] Determine a target reference signal and first measurement information of the target reference signal according to the positioning request information and the first configuration information; or

[0150] Determine a target reference signal and first measurement information of the target reference signal according to the positioning capability information, the positioning request information and the first configuration information of the terminal;

[0151] Here, the positioning request information indicates the current positioning requirements of the terminal, including but not limited to positioning accuracy, latency, etc. In this way, on the one hand, the terminal can determine the target reference signal and the first measurement information of the target reference signal in combination with its own positioning capability information and the first configuration information previously obtained. On the other hand, the terminal can determine the target reference signal and the first measurement information of the target reference signal in combination with the positioning request information and the first configuration information previously obtained; or, the terminal combines the positioning capability information of the terminal, the positioning request information and the first configuration information to jointly determine the target reference signal and the first measurement information of the target reference signal.

[0152] For example: When the positioning request information indicates that the positioning accuracy requirement is high, if PRS, CSI-RS, TRS and SSB are configured in the first configuration information, PRS is selected as the target reference signal, or a signal with a larger bandwidth is selected as the target reference signal, or a combination of several signals with a larger bandwidth is selected as the target reference signal. When the positioning request information indicates that the delay requirement is high, if PRS, CSI-RS, TRS and SSB are configured in the first configuration information, a signal with a shorter period is selected as the target reference signal, etc.

[0153] In order to realize the effectiveness of the terminal configuration of the network side device, in this embodiment, optionally, before step 201, the following is further included:

[0154] Reporting the positioning capability information of the terminal;

[0155] The positioning capability information includes:

[0156] Supported reporting methods; and / or

[0157] The types of target reference signals supported.

[0158] In this way, the network side device can understand the reporting methods supported by the terminal and / or the capabilities of the types of target reference signals supported, and perform better configuration. Of course, the network side device will also inform the terminal of its own supported reporting methods and / or the capabilities of the types of target reference signals supported, and perform capability interaction.

[0159] For example, the supported reporting methods are interacted through NR-ECID-Provide Capabilities. Specifically, the structure of NR-ECID-Provide Capabilities is as follows:

[0160]

[0161] For example, through MeasSupported in ProvideCapabilities, a bit string is used to indicate the measurement type that the terminal can provide, that is, the type of target reference signal supported by the terminal. Specifically, the structure implementation of MeasSupported is as follows:

[0162]

[0163]

[0164] In addition, for the first measurement information reported by the terminal, the network side device will request the terminal to report the required first measurement information for the convenience of subsequent processing. Therefore, optionally, before reporting the first measurement information, it also includes:

[0165] Third request information sent by a network side device is received, where the third request information is used to request the first measurement information reported by the terminal.

[0166] Here, the third request information may include the type of the target reference signal, requesting to report the first measurement information corresponding to the type of the carried target reference signal; it may also include the type of measurement information, requesting to report the first measurement information corresponding to the type of the carried measurement information. In this way, by receiving the third request information sent by the network side device, the terminal understands the network side device's expectations for the reported first measurement information, that is, what type of first measurement information of the target reference signal, and subsequently can perform targeted reporting based on the third request information. For example, if the third request information requests the first measurement information of TRS, then when the terminal reports, it reports the first measurement information of the corresponding TRS. Here, the third request information can be implemented by receiving a bit string in the request location information Request Location Information, specifically, as shown below:

[0167]

[0168]

[0169] Next, combine Figure 3 The application of the method of the embodiment of the present application is described as follows:

[0170] Step 301: The network side device and the terminal perform capability interaction, including whether to support triggered reporting and periodic reporting, and the type of first measurement information that can be supported.

[0171] Step 302: The terminal sends a request to the network side device via a Request Assistance Data message, where the request includes an indication of the type of first configuration information expected by the terminal.

[0172] Step 303: After receiving the request from the terminal, the network side device sends the first configuration information and / or the second configuration information via a Provide Assistance Data message.

[0173] Step 304: After receiving the first configuration information, the terminal determines first measurement information according to the first configuration information.

[0174] Step 305: (optional) the terminal reports first measurement information.

[0175] Step 306: After receiving the second configuration information, the terminal determines the second measurement information according to the first measurement information obtained from two consecutive measurements, and determines the reporting behavior according to the second configuration information and the second measurement information.

[0176] Step 307: (optional) the network side device sends RequestLocationInformation to indicate the type of first measurement information that the network side device expects the terminal to report.

[0177] Step 308, if configured to trigger reporting, then when the second measurement information is greater than or equal to the corresponding threshold in the second configuration information, report immediately and request the third configuration information; if configured to periodic reporting, when the second measurement information is greater than or equal to the corresponding threshold in the second configuration information, report in the next reporting period and request the third configuration information; if configured to periodic reporting, when the second measurement information is less than the corresponding threshold in the second configuration information, and the time interval between the next reporting period and the last reporting is greater than the reporting period threshold, report in the next reporting period and request the third configuration information.

[0178] To summarize, the method of an embodiment of the present application first receives first configuration information sent by a network side device for indicating the configuration of a target reference signal for positioning measurement, determines the target reference signal corresponding to the positioning measurement, and understands the relevant configuration of the target reference signal, thereby determining the first measurement information of the target reference signal.
