[0035] The positioning method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0036] like Figure 2 As shown, an embodiment of the present application provides a positioning method 200, which can be executed by a communication device. In other words, the method can be executed by software or hardware installed in the communication device. The method includes the following steps.

[0037] S202: The communication device determines a positioning method, where the positioning method includes unlicensed frequency band positioning or licensed frequency band positioning.

[0038] The communication device in this embodiment may be a location management function (LMF) or a terminal.

[0039] Optionally, in this embodiment, the communication device determines the positioning mode, including the communication device determining the positioning mode according to at least one of the following:

[0040] 1) If the bandwidth of the licensed frequency band positioning reference signal supported by the terminal cannot meet the positioning accuracy requirement, and the bandwidth of the unlicensed frequency band positioning reference signal supported by the terminal meets the positioning accuracy requirement, then determining that the positioning mode is unlicensed frequency band positioning.

[0041] The positioning reference signal in this embodiment may be an uplink positioning reference signal, such as a sounding reference signal (SRS); or may be a downlink positioning reference signal, such as a positioning reference signal (PRS).

[0042] 2) The priority of unlicensed frequency band positioning is higher than the priority of licensed frequency band positioning.

[0043] 3) If the terminal has the capability of unlicensed frequency band positioning, the positioning method is determined to be unlicensed frequency band positioning.

[0044] 4) If the terminal has the capability of unlicensed frequency band positioning and satisfies at least one of the following requirements: the period of the location service is greater than or equal to the first threshold and the delay requirement is greater than or equal to the second threshold, then the positioning method is determined to be unlicensed frequency band positioning.

[0045] 5) Sidelink (SL) positioning takes precedence over the positioning of the terminal and the network through the air interface, the SL positioning includes unlicensed frequency band positioning or licensed frequency band positioning, the positioning of the terminal and the network through the air interface includes unlicensed frequency band positioning or licensed frequency band positioning; wherein, the positioning of the terminal and the network through the air interface includes, for example, NR positioning.

[0046] S204: The communication device obtains positioning result related information based on the positioning method, where the positioning result related information includes measurement results or position related information.

[0047] In this step, the measurement result obtained by the communication device may be a measurement result of a positioning reference signal; and the position-related information obtained by the communication device may be a positioning result.

[0048] According to the positioning method provided in the embodiment of the present application, the communication device can determine the positioning method from unlicensed frequency band positioning and authorized frequency band positioning, and obtain relevant information about the positioning result based on the determined positioning method, thereby avoiding the problem that the communication device cannot be positioned due to the inability to know the positioning method used, and improving the success rate of positioning.

[0049] As mentioned above, the communication device may be an LMF or a terminal. Hereinafter, the positioning method provided in the embodiment of the present application will be described in detail by taking the communication device being an LMF as an example.

[0050] Optionally, the communication device determines the positioning mode, comprising the communication device determining the positioning mode based on first information, wherein the first information includes at least one of the following:

[0051] 1) Relevant information of location services, such as the period requirement, accuracy requirement, delay requirement, low power consumption and high precision positioning (LPHAP) of location services.

[0052] 2) Information in the response message sent by the access network device during the Transmission and Reception Point (TRP) information exchange process (TRPInformation Exchange).

[0053] For example, during the TRP information exchange process, LMF can request the Next Generation Radio Access Network / 5G Radio Access Network (NG-RAN) node to provide specific information of TRP.

[0054] 3) Terminal capability information, including capability information related to unlicensed frequency band positioning, such as whether NR-U positioning is supported and whether SL-U positioning is supported.

[0055] For example, in the LTE Positioning Protocol (LPP) capability transfer process, the LMF requests and obtains the capability information of the terminal.

[0056] Optionally, based on the above embodiments, before the communication device obtains information related to the positioning result based on the positioning method, the method further includes: the LMF sends a first request message to the first access network device, the first request message includes a requested positioning reference signal sending parameter, and the positioning reference signal sending parameter includes at least one of the following:

[0057] 1) Frequency information, such as FR1 unlicensed frequency band and FR2 unlicensed frequency band.

[0058] 2) The positioning reference signal transmission bandwidth information associated with the frequency information.

[0059] 3) Frequency preference information, such as preference for unlicensed frequency bands.

[0060] 4) Mandatory frequency information, such as mandatory unlicensed frequency bands.

[0061] In this embodiment, the first request message sent by the LMF to the first access network device may also include positioning-related information, where the positioning-related information includes at least one of the following:

[0062] 1) Relevant information of location services, such as the period requirement, accuracy requirement, delay requirement, low power consumption and high precision positioning (LPHAP) of location services.

[0063] 2) Capability information of the terminal, wherein the capability information includes capability information related to unlicensed frequency band positioning.

[0064] Optionally, after the LMF sends the first request message to the first access network device, the method further includes: the LMF receiving a first response message from the first access network device, the first response message including information about positioning reference signal resources, and the information about positioning reference signal resources includes at least one of the following:

[0065] 1) Positioning reference signal resources including frequency domain resources.

[0066] 2) A positioning reference signal resource comprising frequency domain resources and a first time domain resource.

[0067] 3) A positioning reference signal resource comprising a frequency domain resource and a second time domain resource.

[0068] Optionally, the frequency domain resources and the second time domain resources are unlicensed frequency band resources and are resources shared by channel occupancy time (COT).

[0069] 4) An indication that the positioning reference signal resource is an unlicensed frequency band positioning reference signal resource.

[0070] The first time domain resource is used to assist in determining the specific location of the positioning reference signal time domain resource. For example, the first time domain resource only includes the period of the positioning reference signal time domain resource, and the first time domain resource cannot determine the specific location of the positioning reference signal time domain resource.

[0071] The second time domain resource is used to directly determine the specific position of the positioning reference signal time domain resource. For example, the second time domain resource includes the period of the positioning reference signal time domain resource and an indication of determining the specific position of the positioning reference signal time domain resource, such as the number of positioning reference signal time domain offset time slots.

[0072] In one example, when the information of the positioning reference signal resources includes positioning reference signal resources of frequency domain resources and second time domain resources, the information of the positioning reference signal resources also includes time period-related information, and the time period-related information is used to indicate the time information of the access network device or terminal to detect or send the positioning reference signal.

[0073] Optionally, the information related to the time period is related to the configuration of continuous LBT failures. For example, the value of the information related to the time period is the number of times or time corresponding to continuous LBT failures.

[0074] Optionally, the configuration of the continuous LBT failure is related to the relevant information of the location service. In this example, the access network device can refer to the received information related to the location service to configure the continuous LBT failure, for example, the time of the continuous LBT failure is less than the positioning delay.

[0075] The information related to the time period may be, for example, the duration of a timer or the value of a counter; the uses of the information related to the time period include, for example: 1) if the access network device fails to detect the SRS signal within the timer or counter times, it shall give up detecting the SRS signal; and if the UE fails to successfully send the SRS within the timer or counter times, it shall give up sending the SRS signal; 2) if the UE fails to successfully complete Listen Before Talk (LBT) and send SRS resources before the timer expires, it shall give up sending the SRS resources; 3) the counter is an SRS resource attempt sending counter. If the UE fails to successfully complete LBT and send SRS resources within each SRS resource period, the counter shall be reduced by 1. When the counter is 0, the SRS resource sending shall be given up.

[0076] In an example, when the information of the positioning reference signal resource includes a positioning reference signal resource of a frequency domain resource or a positioning reference signal resource including a frequency domain resource and a first time domain resource, the information of the positioning reference signal resource also includes information related to a time domain indication, and the information related to the time domain indication is used for one of the following:

[0077] 1) After receiving the positioning reference signal configuration, the terminal waits for the first access network device to execute the LBT process and receives the positioning reference signal time domain resource information obtained by the first access network device. This example is applicable to the downlink positioning method.

[0078] 2) The terminal executes the LBT process and reports the time domain resource information of the positioning reference signal obtained after the LBT is successful to the first access network device. This example is applicable to the uplink positioning method.

[0079] The positioning reference signal time domain resource information mentioned in this example includes, for example, the time domain offset time slot number for SRS transmission and the time domain offset time slot number for PRS transmission.

[0080] Optionally, based on the above embodiments, the method further includes at least one of the following:

[0081] 1) The LMF sends a first message to the terminal, where the first message includes a positioning reference signal configuration.

[0082] 2) The LMF sends a second request message to the terminal, where the second request message is used to request the terminal to perform positioning reference signal measurement.

[0083] The second request message may include response time information, and the response time information is related to LBT. Considering that the access network device may encounter LBT failure when sending PRS, and the UE may encounter LBT failure when sending Provide Location Information message, the response time will be set larger, greater than the response time in the authorized frequency band positioning.

[0084] Optionally, based on the above embodiments, the method also includes: the LMF sends a third request message to the second access network device, the third request message includes a positioning reference signal configuration, and is used to request the second access network device to perform positioning reference signal measurement.

[0085] The third request message shown may include response time information, and the response time information is related to LBT. Considering that the terminal may encounter LBT failure when sending SRS, the access network device may encounter LBT failure when sending a measurement response (MEASUREMENT RESPONSE) message, therefore, the response time will be set larger, greater than the response time in the authorized frequency band positioning.

[0086] Combination of the above Figure 2 The positioning method according to the embodiment of the present application is described in detail. Figure 3 A positioning method according to another embodiment of the present application is described in detail. It can be understood that the interaction between the network side device and the terminal described by the network side device is similar to Figure 2 The descriptions on the terminal side in the methods shown are the same or corresponding, and to avoid repetition, the relevant descriptions are appropriately omitted.

[0087] Figure 31 is a schematic diagram of the implementation flow of the positioning method of the embodiment of the present application, which can be applied to a first access network device, such as a service base station of a terminal. Figure 3 As shown, the method 300 includes the following steps.

[0088] S302: The first access network device sends a first response message to the LMF, and the first response message includes information about positioning reference signal resources, and the information about positioning reference signal resources includes at least one of the following: a positioning reference signal resource including frequency domain resources; a positioning reference signal resource including frequency domain resources and a first time domain resource; a positioning reference signal resource including frequency domain resources and a second time domain resource; an indication that the positioning reference signal resource is an unlicensed frequency band positioning reference signal resource.

[0089] The first time domain resource is used to assist in determining the specific location of the positioning reference signal time domain resource, and the second time domain resource is used to directly determine the specific location of the positioning reference signal time domain resource.

[0090] In the positioning method provided in the embodiment of the present application, the first access network device sends a first response message to the LMF, and the first response message includes information about positioning reference signal resources, so that the terminal, access network device or LMF can use unlicensed frequency band positioning or authorized frequency band positioning to perform positioning, thereby improving the success rate of positioning.

[0091] Optionally, as an embodiment, when the information of the positioning reference signal resources includes positioning reference signal resources of frequency domain resources and second time domain resources, the information of the positioning reference signal resources also includes time period related information, and the time period related information is used to indicate the time information of the access network device or terminal to detect or send the positioning reference signal.

[0092] Optionally, as an embodiment, when the information of the positioning reference signal resource includes a positioning reference signal resource of a frequency domain resource or a positioning reference signal resource including a frequency domain resource and a first time domain resource, the information of the positioning reference signal resource further includes information related to a time domain indication, and the information related to the time domain indication is used for one of the following:

[0093] 1) After receiving the positioning reference signal configuration, the terminal waits for the first access network device to execute the LBT process and receives the positioning reference signal time domain resource information obtained by the first access network device.

[0094] 2) The terminal executes the LBT process and reports the time domain resource information of the positioning reference signal obtained after the LBT is successful to the first access network device.

[0100] Optionally, as an embodiment, the first access network device sends a first response message to the LMF, including: when the first access network device receives the positioning reference signal time domain resource information fed back by the terminal, the first access network device sends a first response message to the LMF; wherein the positioning reference signal time domain resource information is obtained after the terminal LBT is successful.

[0101] To illustrate the positioning method provided in the embodiments of the present application in detail, several specific embodiments will be described below.

[0102] Embodiment 1

[0103] This embodiment mainly introduces the unlicensed frequency band uplink positioning method, such as Figure 4 As shown, the following steps are included:

[0104] Step 1 (not shown): AMF receives a location service request message (such as Location service request), which comes from one of the 5GC LCS entities (MT-LR, mobile terminated location request), UE (MO-LR, mobile originated LR), and serving AMF (NI-LR, network induced LR).

[0105] The location service request information may include relevant information of the location service, such as the period requirement, accuracy requirement, delay requirement, LPHAP (Low Power Consumption High Accuracy Positioning), etc. of the location service. The delay is the difference between the actual positioning time and the expected positioning time. For example, if the positioning period is 20s, the terminal should be positioned in 20s, 40s, ..., but the terminal competes for the channel in 21s and completes the positioning in 22s, then the positioning delay is 2s.

[0106] Step 2 (not shown): AMF sends the location service request message received in step 1 to LMF.

[0107] Step 3: During the TRP information exchange process, the LMF requests the NG-RAN node to provide the specific information of the TRP.

[0108] Step 4: LPP capability transfer process, LMF requests and obtains UE capability information.

[0109] Among them, the UE capability information may include capability information related to unlicensed frequency band positioning, such as whether NR-U positioning is supported and whether SL-U positioning is supported.

[0110] The frequency band resources used in the LPP capability transmission process may be unlicensed frequency band resources or licensed frequency band resources.

[0111] Step 5: The LMF determines a positioning method according to the received information, where the positioning method includes unlicensed frequency band positioning or licensed frequency band positioning. This step corresponds to S202 in the embodiment 200.

[0112] In this step, the "information received" by LMF includes at least one of the following:

[0113] 1) Relevant information of the location service in step 1.

[0114] 2) Information in the base station response message received in step 3.

[0115] 3) The UE capability information received in step 4.

[0116] The specific decision criteria of "determining the positioning method" include at least one of the following:

[0117] 1) If the bandwidth of the uplink positioning reference signal in the licensed frequency band supported by the terminal cannot meet the positioning accuracy requirement, and the bandwidth of the uplink positioning reference signal in the unlicensed frequency band supported by the terminal meets the positioning accuracy requirement, then the positioning mode is determined to be unlicensed frequency band positioning.

[0118] 2) The priority of unlicensed frequency band positioning is higher than the priority of licensed frequency band positioning.

[0119] 3) If the terminal has the capability of unlicensed frequency band positioning, the positioning method is determined to be unlicensed frequency band positioning.

[0120] 4) If the terminal has the capability of unlicensed frequency band positioning and satisfies at least one of the following requirements: the period of the location service is greater than or equal to the first threshold and the delay requirement is greater than or equal to the second threshold, then the positioning method is determined to be unlicensed frequency band positioning.

[0121] 5) Sidelink (SL) positioning takes precedence over the positioning of the terminal and the network through the air interface, the SL positioning includes unlicensed frequency band positioning or licensed frequency band positioning, the positioning of the terminal and the network through the air interface includes unlicensed frequency band positioning or licensed frequency band positioning; wherein, the positioning of the terminal and the network through the air interface includes, for example, NR positioning.

[0122] Step 6: LMF sends a position information request (POSITIONING INFORMATION REQUEST) message to the base station.

[0123] The "location information request message" includes at least one of the following:

[0124] 1) Requested SRS transmission parameters.

[0125] 2) Positioning related information.

[0126] The requested SRS transmission parameter includes at least one of the following:

[0127] 1) Frequency information, such as FR1 unlicensed frequency band and FR2 unlicensed frequency band.

[0128] 2) SRS sends bandwidth request associated with frequency information.

[0129] 3) Frequency preference, such as unlicensed frequency bands.

[0130] 4) Mandatory frequency, such as mandatory unlicensed frequency band.

[0131] The positioning-related information includes at least one of the following:

[0132] 1) Relevant information of the location service in step 1.

[0133] 2) UE capability information, such as UE unlicensed frequency band positioning capability information.

[0134] Step 7a: After receiving the POSITIONING INFORMATION REQUEST message sent by the LMF, the base station determines the uplink SRS resource and then sends the SRS configuration to the UE.

[0135] The resource used to send the SRS configuration to the UE is at least one of the following: a licensed frequency band resource; an unlicensed frequency band resource.

[0136] The SRS is configured as at least one of the following:

[0137] 1) SRS resources including frequency domain resources.

[0138] 2) SRS resources including frequency domain resources and first time domain resources. The first time domain resources are used to assist in determining the specific location of the SRS time domain resources. For example, the first time domain resources only include the period of the SRS time domain resources, and the first time domain resources cannot determine the specific location of the SRS time domain resources.

[0139] 3) An SRS resource including a frequency domain resource and a second time domain resource. The second time domain resource is used to directly determine the specific location of the SRS time domain resource. For example, the second time domain resource includes a period of the SRS time domain resource and an indication of determining the specific location of the SRS time domain resource, such as the number of SRS time domain offset time slots.

[0140] Optionally, the frequency domain resources and the second time domain resources are unlicensed frequency band resources and are resources shared by the channel occupancy time (COT), that is, resources shared after successful LBT in the unlicensed frequency band when the base station sends the SRS configuration to the UE.

[0141] 4) The SRS resource is an indication of an unlicensed frequency band positioning reference signal resource.

[0142] In one example, when the SRS configuration includes SRS resources of frequency domain resources and second time domain resources, the SRS configuration also includes time period related information, and the time period related information is used to indicate the time information of the access network device or terminal to detect or send the SRS configuration.

[0143] The information related to the time period may be, for example, the duration of a timer or the value of a counter; the uses of the information related to the time period include, for example: 1) when the access network device fails to detect the SRS signal within the timer or within counter times, it gives up detecting the SRS signal, and when the UE fails to successfully send the SRS within the timer or within counter times, it gives up sending the SRS signal; 2) the counter is an SRS resource attempt to send / receive timer. If the UE fails to successfully complete Listen Before Talk (LBT) and send SRS resources before the timer expires, it gives up sending the SRS resources; 3) the counter is an SRS resource attempt to send counter. If the UE fails to successfully complete LBT and send SRS resources within each SRS resource period, the counter is -1. When the counter is 0, the SRS resource is given up.

[0144] Optionally, the information related to the time period is related to the configuration of continuous LBT failures. For example, the value of the information related to the time period is the number of times or time corresponding to continuous LBT failures.

[0145] Optionally, the configuration of the continuous LBT failure is related to the location service related information. In this example, the base station can refer to the location service related information received in step 6 to configure the continuous LBT failure, for example, the time of the continuous LBT failure is less than the positioning delay.

[0146] In an example, when the SRS configuration includes SRS resources of frequency domain resources, or includes SRS resources of frequency domain resources and first time domain resources, the SRS configuration also includes information related to time domain indication.

[0147] Among them, the information related to the time domain indication is used to instruct the UE to perform LBT after receiving the SRS configuration, and report the SRS time domain resource information obtained after the LBT is successful to the base station. For example, the SRS resource time domain offset feedback indication, if the SRS configuration does not include the SRS resource time domain offset time slot number, then the terminal needs to send the SRS time domain offset time slot number to the network after successfully completing the LBT. The indication can be an explicit or implicit indication (implicit indication means that the SRS configuration does not include the SRS resource time domain offset time slot number).

[0148] Step 7b (optional): The UE receives the SRS configuration sent by the base station. If the SRS configuration does not include some information about time domain resources (such as the number of time domain offset time slots of the SRS resource), the terminal reports the SRS time domain resource information to the network after successfully completing the LBT, such as the number of time domain offset time slots sent by the SRS.

[0149] Step 8: The base station sends a position information response (POSITIONING INFORMATION RESPONSE) message to the LMF, which includes the information of the SRS resources.

[0150] The information containing the SRS resource is at least one of the following:

[0151] 1) SRS resources including frequency domain resources and second time domain resources.

[0152] 2) An indication that the SRS resource is an unlicensed frequency band.

[0153] When the SRS resource includes frequency domain resources and second time domain resources, the information related to the time period in step 7a (eg, SRS resource attempt to send / receive timer, SRS resource attempt to send / receive counter) is also included.

[0154] The specific time when the base station sends the POSITIONING INFORMATION RESPONSE message to the LMF is at least one of the following:

[0155] 1) When the SRS configuration in step 7a includes information related to the time domain indication, the base station sends the POSITIONING INFORMATION RESPONSE message after step 7b (ie, receiving some information about the SRS time domain resources obtained after the LBT success fed back by the UE).

[0156] 2) When the SRS configuration in step 7a includes information related to the time period, the base station can send the POSITIONING INFORMATION RESPONSE message after configuring the SRS resources in step 7a.

[0157] Step 9: LMF sends the SRS configuration to the relevant base station through an NRPPa message, such as a measurement request (MEASUREMENT REQUEST) message, and requests the relevant base station to perform SRS measurement based on the SRS configuration.

[0158] The SRS configuration may also include information related to the time period (eg, SRS resource attempt to send / receive timer, SRS resource attempt to send / receive counter), which is used by the base station to give up detecting the SRS signal when the SRS signal is not detected within the timer time or counter times in step 10.

[0159] The response time (Response Time) set in the MEASUREMENT REQUEST message may be set to be larger (considering that the UE encounters an LBT failure when sending an SRS, and the base station may encounter an LBT failure when sending a MEASUREMENT RESPONSE message).

[0160] Step 10: The relevant base station performs SRS measurement based on the configuration.

[0161] Step 11: The relevant base station feeds back the SRS measurement result via an NRPPa message, such as a measurement response (Measurement Response). This step corresponds to S204 in embodiment 200.

[0162] Embodiment 2

[0163] This embodiment mainly introduces the unlicensed frequency band downlink positioning method, such as Figure 5 As shown, the following steps are included:

[0164] Step 1 (not shown): AMF receives a location service request message (such as Location service request), which comes from one of the 5GC LCS entities (MT-LR, mobile terminated location request), UE (MO-LR, mobile originated LR), and serving AMF (NI-LR, network induced LR).

[0165] The location service request information may include relevant information of the location service, such as the period requirement, accuracy requirement, delay requirement, LPHAP (low power consumption and high accuracy positioning) and the like of the location service.

[0166] Step 2 (not shown): AMF sends the location service request message received in step 1 to LMF.

[0167] Step 3: LPP capability transfer process, LMF requests and obtains UE capability information.

[0168] Among them, the UE capability information may include capability information related to unlicensed frequency band positioning, such as whether NR-U positioning is supported and whether SL-U positioning is supported.

[0169] The frequency band resources used in the LPP capability transmission process may be unlicensed frequency band resources or licensed frequency band resources.

[0170] Step 4: The LMF determines a positioning method according to the received information. The positioning method includes unlicensed frequency band positioning or licensed frequency band positioning. This step corresponds to S202 in embodiment 200.

[0171] In this step, the "information received" by LMF includes at least one of the following:

[0172] 1) Relevant information of the location service in step 1.

[0173] 2) Information in the base station response message received in step 3.

[0174] 3) The UE capability information received in step 4.

[0175] The specific decision criteria of "determining the positioning method" include at least one of the following:

[0176] 1) If the bandwidth of the downlink positioning reference signal in the authorized frequency band supported by the terminal cannot meet the positioning accuracy requirement, and the bandwidth of the downlink positioning reference signal in the unlicensed frequency band supported by the terminal meets the positioning accuracy requirement, then the positioning mode is determined to be unlicensed frequency band positioning.

[0177] 2) The priority of unlicensed frequency band positioning is higher than the priority of licensed frequency band positioning.

[0178] 3) If the terminal has the capability of unlicensed frequency band positioning, the positioning method is determined to be unlicensed frequency band positioning.

[0179] 4) If the terminal has the capability of unlicensed frequency band positioning and satisfies at least one of the following requirements: the period of the location service is greater than or equal to the first threshold and the delay requirement is greater than or equal to the second threshold, then the positioning method is determined to be unlicensed frequency band positioning.

[0180] 5) Sidelink (SL) positioning takes precedence over the positioning of the terminal and the network through the air interface, the SL positioning includes unlicensed frequency band positioning or licensed frequency band positioning, the positioning of the terminal and the network through the air interface includes unlicensed frequency band positioning or licensed frequency band positioning; wherein, the positioning of the terminal and the network through the air interface includes, for example, NR positioning.

[0181] Steps 5 and 6 are the TRP information exchange process.

[0182] Step 5: LMF sends a TRP information request (TRP INFORMATION REQUEST) message to the base station.

[0183] The TRP information request message includes at least one of the following:

[0184] 1) Requested PRS transmission parameters.

[0185] 2) Positioning related information.

[0186] The positioning-related information includes at least one of the following:

[0187] 1) Relevant information of the location service in step 1.

[0188] 2) The ability of UE to locate in unlicensed frequency bands.

[0189] The requested PRS transmission parameter includes at least one of the following:

[0190] 1) Frequency information, such as FR1 unlicensed frequency band and FR2 unlicensed frequency band.

[0191] 2) SRS sends bandwidth request associated with frequency information.

[0192] 3) Frequency preference, such as unlicensed frequency bands.

[0193] 4) Mandatory frequency, such as mandatory unlicensed frequency band.

[0194] Step 6: After receiving the TRP information request message sent by LMF, the base station feeds back the PRS configuration to LMF through a TRP information response (TRP INFORMATION RESPONSE) message.

[0195] The PRS is configured as at least one of the following:

[0196] 1) PRS resources including frequency domain resources.

[0197] 2) A PRS resource including frequency domain resources and first time domain resources, wherein the first time domain resources are used to assist in determining the specific location of the PRS time domain resources, for example, the first time domain resources only include the period of the PRS time domain resources, and the first time domain resources cannot determine the specific location of the PRS time domain resources.

[0198] 3) A PRS resource including a frequency domain resource and a second time domain resource. The second time domain resource is used to directly determine the specific location of the PRS time domain resource. For example, the second time domain resource includes a period of the PRS time domain resource and an indication of determining the specific location of the PRS time domain resource, such as the number of PRS time domain offset time slots.

[0199] Optionally, the frequency domain resources and the second time domain resources are unlicensed frequency band resources and are resources shared by the channel occupancy time (COT), that is, resources shared after the unlicensed frequency band LBT is successful when the base station sends the PRS configuration to the UE.

[0200] 4) The PRS resource is an indication of an unlicensed frequency band positioning reference signal resource.

[0201] In one example, when the PRS configuration includes PRS resources of frequency domain resources and second time domain resources, the PRS configuration also includes time period related information, and the time period related information is used to indicate the time information of the access network device or terminal to detect or send the PRS configuration.

[0202] The information related to the time period may be, for example, the duration of a timer or the value of a counter. The uses of the time period information include, for example: 1) if the UE fails to detect the PRS signal within the timer or within counter times, it abandons detecting the PRS signal. At the same time, if the base station fails to successfully send the PRS within the timer or within counter times, it abandons sending the PRS signal; 2) the counter is a PRS resource attempt to send / receive timer. If the UE fails to successfully detect the PRS resource before the timer expires, it abandons the detection of the PRS resource; 3) the counter is a PRS resource attempt to send / receive counter. If the UE fails to successfully detect the PRS in each PRS resource cycle, the PRS resource counter is reduced by 1. When the counter is 0, the detection of the PRS resource is abandoned.

[0203] Optionally, the information related to the time period is related to the configuration of continuous LBT failures. For example, the value of the information related to the time period is the number of times or time corresponding to continuous LBT failures.

[0204] Optionally, the configuration of the continuous LBT failure is related to the location service related information. In this example, the base station can refer to the location service related information received in step 5 to configure the continuous LBT failure, for example, the time of the continuous LBT failure is less than the positioning delay.

[0205] In an example, when the PRS configuration includes PRS resources of frequency domain resources, or includes PRS resources of frequency domain resources and first time domain resources, the PRS configuration also includes information related to time domain indication.

[0206] Among them, the information related to the time domain indication is used to instruct the UE to wait for the base station to perform LBT after receiving the PRS configuration. The PRS time domain resources obtained after the base station LBT is successful will be subsequently reported to the LMF, and the LMF will inform the UE. For example, the PRS resource time domain offset feedback indication, if the PRS configuration does not include the number of PRS resource time domain offset time slots, the base station needs to send the number of time domain offset time slots sent by the PRS to the LMF after successfully completing the LBT. The indication can be an explicit or implicit indication (the implicit indication is that the PRS configuration does not include the number of PRS resource time domain offset time slots).

[0207] Step 7: After receiving the message in step 6, LMF sends PRS configuration information to UE.

[0208] Step 8: LMF sends a request location information (RequestLocationInformation) message to the UE, in which the response time (Response Time) will be set larger (considering that the base station encounters LBT failure when sending PRS, the UE will encounter LBT failure when sending the ProvideLocationInformation message).

[0209] Step 9: UE sends a Provide Location Information (ProvideLocationInformation) message to LMF. This step corresponds to S204 in embodiment 200.
