[0053] In the following, in combination with the accompanying drawings, a signal sending method, an information sending method, a positioning measurement method and a device provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0054] See also Figure 2 , Figure 2 is a flow chart of a signal sending method provided in an embodiment of the present application, such as Figure 2 As shown, the following steps are included:

[0055] Step 201: The first device determines first configuration information of a reference signal for positioning measurement, where the first configuration information includes at least one of the following: time information for obtaining a positioning result, time information for sending the reference signal, time information for LBT, and an indication for executing LBT in advance.

[0056] The first device may be a terminal or a network side device.

[0057] The first configuration information for determining the reference signal for positioning measurement may be the first configuration information of the reference signal for positioning measurement determined by the first device itself; or, the first configuration information for determining the reference signal for positioning measurement may be the first configuration information of the reference signal for positioning measurement received by the first device from other devices, or the configuration information may be determined after receiving the first configuration information sent by other devices.

[0058] The reference signal may be a sounding reference signal (SRS) or a positioning reference signal (PRS). For example, when the first device is a terminal, the reference signal may be an SRS, and when the first device is a network side device, the reference signal may be a PRS.

[0059] The time information of obtaining the above positioning result can be the time when the device or client or positioning service needs to obtain the positioning result, such as the location service (LCS) client, AF or terminal specifies a future time to obtain the current location of the terminal, and this time is the time information of obtaining the positioning result. The time of obtaining the above positioning result can be a scheduled location time (Scheduled Location Time).

[0060] In some embodiments, the time information for obtaining the above positioning results can represent periodic time. For example, if the time when the LCS client, terminal or AMF initiates the location service request is 10:00:00, then the time information for obtaining the positioning results is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which is periodic positioning every 15 seconds.

[0061] The transmission time information of the reference signal may indicate the time when the reference signal is completed to be transmitted or the transmission time of the reference signal.

[0062] The time information of the LBT may indicate the time when the LBT is completed or the time when the LBT is executed. The time information of the LBT is earlier than the time information of obtaining the positioning result or the time corresponding to the sending time information of the reference signal.

[0063] The indication of performing LBT in advance is used to instruct the first device to perform LBT in advance.

[0064] Step 202: The first device performs LBT in advance based on the first configuration information.

[0065] The aforementioned early execution of LBT refers to executing LBT in advance before sending a reference signal, for example, executing LBT in a positioning preparation phase, or executing LBT before a positioning preparation phase.

[0066] The first device performing LBT in advance based on the first configuration information includes:

[0067] The first device performs LBT in advance based on at least one of the acquisition time information of the positioning result, the sending time information of the reference signal, the time information of the LBT, or the indication of performing LBT in advance.

[0068] For example: the first device executes LBT in advance based on the acquisition time information of the positioning result, such as the first device executes LBT in advance before the time corresponding to the acquisition time information of the positioning result by default or by protocol agreement; another example: the first device executes LBT in advance based on the sending time information of the reference signal, such as the first device executes LBT in advance before the time corresponding to the sending time information of the reference signal by default or by protocol agreement; another example: the first device executes LBT in advance based on the time information of LBT, such as the first device should LBT at the time corresponding to the time information; another example: the first device executes LBT in advance based on the indication of executing LBT in advance, and the specific advance time may be a protocol agreement or a network side configuration.

[0069] Step 203: The first device sends the reference signal based on the result of the LBT.

[0070] The above-mentioned sending of the reference signal based on the result of the LBT can be understood as performing LBT in advance before sending the reference signal, and after the LBT succeeds, sending the reference signal on the resources corresponding to the reference signal. For example: after the LBT succeeds, the reference signal is sent on the time domain resources of the reference signal, or the reference signal is sent at the time corresponding to the sending time information of the reference signal, or the reference signal is sent at the time corresponding to the acquisition time information of the positioning result, or the reference signal is sent at a specific time after the time corresponding to the time information of the LBT, and the specific time can be a protocol agreement or a network side pre-configuration, or the reference signal is sent at a specific time after the execution of the LBT, and the specific time can be a protocol agreement or a network side pre-configuration.

[0071] In an embodiment of the present application, the above steps can be used to execute LBT in advance based on the first configuration information, so that the reference signal can be sent in time, thereby improving the positioning performance of the device.

[0072] In the embodiment of the present application, the first device sends the above-mentioned reference signal for uplink positioning measurement, downlink positioning measurement or sidelink (SL) positioning measurement.

[0073] In some embodiments, when the above-mentioned first device is a terminal, sending a reference signal can achieve uplink positioning measurement, that is, the wireless access device measures the above-mentioned reference signal; when the above-mentioned first device is a terminal, sending a reference signal can achieve SL positioning measurement, that is, another terminal measures the above-mentioned reference signal; when the above-mentioned first device is a wireless access network device, sending a reference parameter can achieve downlink positioning measurement, that is, the terminal measures the above-mentioned reference signal.

[0074] As an optional implementation manner, the execution time of the LBT performed in advance by the first device includes the time corresponding to the time information of the LBT; or,

[0075] The first device executes the LBT in advance by at least one LBT time interval corresponding to the time information of obtaining the positioning result; or,

[0076] The first device performs LBT in advance for a time interval corresponding to the time information of obtaining the positioning result and the time of continuous LBT;

[0077] The first device performs LBT in advance by a time interval corresponding to the sending time information of the reference signal by at least one LBT time; or

[0078] The first device advances the execution time of LBT to a time interval corresponding to the sending time information of the reference signal for consecutive LBT times.

[0079] Among them, the above-mentioned at least one time interval may be agreed upon by the protocol or configured on the network side.

[0080] The above-mentioned continuous LBT (Continuous LBT, C-LBT) can be a protocol agreement or a network side configuration that allows continuous execution of LBT. Specifically, it can be a protocol agreement or a network side configuration of the number of C-LBTs, such as allowing continuous execution of C times of LBT, where C is a positive integer.

[0081] In the above implementation, due to the time interval of at least one LBT or the time interval of consecutive LBT, the first device can reserve sufficient time to perform LBT before sending the reference signal, so that the reference signal can be sent in time, thereby improving the positioning performance and meeting the positioning delay and period requirements of the positioning service.

[0082] In this implementation, it can be applied to uplink positioning measurement, downlink positioning measurement, or SL positioning measurement.

[0083] As an optional implementation manner, the performing LBT in advance includes:

[0084] Perform LBT during the positioning preparation phase; or

[0085] LBT is performed before the positioning preparation phase.

[0086] The positioning preparation phase may be a positioning preparation phase defined by a protocol or configured on the network side. For example, when the LCS client, AF or terminal requests the current location of the terminal, the positioning preparation phase starts.

[0087] In this implementation, since LBT is performed in the positioning preparation stage or before the positioning preparation stage, the reference signal can be sent in time, thereby improving the positioning performance and meeting the positioning delay and period requirements of the positioning service.

[0088] In this implementation, it can be applied to uplink positioning measurement, downlink positioning measurement, or SL positioning measurement.

[0089] As an optional implementation manner, the first configuration information further includes at least one of the following:

[0090] frequency related information of the reference signal;

[0091] The unlicensed frequency band configuration information of the reference signal.

[0092] The frequency-related information of the reference signal is used to indicate information such as the frequency band and bandwidth of the reference signal.

[0093] In some implementations, the frequency-related information of the reference signal is used to indicate at least one of the following:

[0094] The frequency band of the periodic reference signal is an authorized frequency band;

[0095] The frequency band of the periodic reference signal is an unlicensed frequency band;

[0096] a transmission bandwidth of the reference signal;

[0097] The frequency band of part of the periodic reference signal is an authorized frequency band, and the frequency band of another part of the periodic reference signal is an unlicensed frequency band;

[0098] multiple sets of unlicensed frequency band configurations of the reference signal;

[0099] Part or all of the unlicensed frequency band resources of the reference signal are channel occupancy time (COT) shared resources;

[0100] The frequency band for sending the first configuration information is an authorized frequency band.

[0101] The frequency band of the periodic reference signal being an authorized frequency band may be that all frequency bands of the periodic reference signal are authorized frequency bands.

[0102] The frequency band of the periodic reference signal being an unlicensed frequency band may mean that all frequency bands of the periodic reference signal are unlicensed frequency bands.

[0103] The transmission bandwidth of the reference signal may be a transmission bandwidth of the reference signal associated with frequency information.

[0104] Since the frequency band of part of the periodic reference signal is the authorized frequency band and the frequency band of the other part of the periodic reference signal is the unlicensed frequency band, the need to perform LBT can be reduced to save device power consumption.

[0105] For example, multiple reference signal configurations are configured, including SRS configurations of licensed frequency bands and reference signal configurations of unlicensed frequency bands, that is, a combination of licensed frequency bands and unlicensed frequency bands is achieved by combining multiple configurations.

[0106] Alternatively, when the frequency band of part of the periodic reference signal is an authorized frequency band, and the frequency band of another part of the periodic reference signal is an unlicensed frequency band:

[0107] The frequency band of the first reference signal of the periodic reference signal is a licensed frequency band, and the frequency bands of the remaining reference signals of the periodic reference signal are unlicensed frequency bands.

[0108] In this way, the first reference signal can be sent without performing LBT, so that the positioning result can be obtained quickly.

[0109] The multiple sets of unlicensed frequency band configurations of the above-mentioned reference signal refer to configuring multiple sets of unlicensed frequency band resources for the above-mentioned reference signal. In this way, if the first device fails in LBT on one set of reference signal configurations, it will immediately switch to other reference signal configurations to try LBT, rather than making a second LBT attempt on the set of reference signal configurations until C-LBT fails, so as to improve the transmission performance of the reference signal.

[0110] In some implementations, the bandwidths of multiple sets of unlicensed frequency band configurations may be different, so that switching from a reference signal with a larger bandwidth to a reference signal with a smaller bandwidth can be achieved, or multiple sets of SRS configurations are associated with different resource block (RB) sets, thereby switching between different RB sets.

[0111] By setting the sending frequency band of the first configuration information to the authorized frequency band, the first device can obtain the first configuration information due to the authorized frequency band, thereby reducing LBT opportunities and reducing the probability of positioning delay exceeding the requirement.

[0112] Part or all of the unlicensed frequency band resources of the reference signal may be COT sharing resources, which means that part or all of the unlicensed frequency band resources of the reference signal are resources shared by other devices after LBT succeeds. This can reduce the LBT opportunities to reduce the probability of positioning delay exceeding the requirements.

[0113] The configuration information related to the unlicensed frequency band of the reference signal is used to indicate the configuration information related to the unlicensed frequency band when the reference signal is the unlicensed frequency band.

[0114] In some implementations, the configuration information related to the unlicensed frequency band of the reference signal includes at least one of the following:

[0115] The latency of location services;

[0116] The relationship between LBT and location service latency.

[0117] The delay of the location service may be the delay required by the location service or the delay configured by the location service. In some implementations, the delay of the location service may be a delay agreed upon by a protocol or configured on the network side.

[0118] The relationship between the above-mentioned LBT and location service delays may be a protocol agreement or a network-side configuration.

[0119] In some implementations, the first device is a wireless access network device, the first configuration information is determined by the first device, and the relationship between the LBT and the delay of the location service includes the following:

[0120] The sum of the first continuous LBT time and the second continuous LBT time is less than or equal to the delay of the location service;

[0121] The second continuous LBT time is less than or equal to the delay of the location service;

[0122] The first continuous LBT time is less than or equal to the delay of the location service;

[0123] Among them, the first continuous LBT time is the continuous LBT time allowed for the core network element to send the first configuration information to the terminal, and the second continuous LBT time is the continuous LBT time allowed for the wireless access network device to successfully send the reference signal once.

[0124] For example: the C-LBT time required for LMF to send the first configuration information (PRS configuration) to the terminal + the C-LBT time required for the wireless access network device to successfully send a PRS <= the delay of the location service. For another example: the C-LBT time required for the wireless access network device to successfully send a PRS <= the delay of the location service. For another example: the C-LBT time required for LMF to successfully send the first configuration information to the terminal <= the delay of the location service.

[0125] Since the second continuous LBT time is less than or equal to the delay of the location service, or the first continuous LBT time is less than or equal to the delay of the location service, it can be achieved that LBT is executed in advance based on the delay of the location service, so that the sending of positioning measurements can meet the delay of the location service to improve the positioning performance.

[0126] In some implementations, the first device is a terminal, the first configuration information is first configuration information sent by a wireless access network device and received by the first device, and the relationship between the LBT and the delay of the location service includes one of the following:

[0127] The sum of the third continuous LBT time and the fourth continuous LBT time is less than or equal to the delay of the location service;

[0128] The fourth continuous LBT time is less than or equal to the delay of the location service;

[0129] The third continuous LBT time is less than or equal to the delay of the location service

[0130] Among them, the third continuous LBT time is the continuous LBT time allowed for the wireless access network device to send the first configuration information to the terminal, and the fourth continuous LBT time is the continuous LBT time allowed for the terminal to successfully send the reference signal once.

[0131] For example: the C-LBT time required for the wireless access network device to send the first configuration information (such as SRS configuration) to the terminal + the C-LBT time required for the terminal to successfully send an SRS <= the delay of the location service. For another example: the C-LBT time required for the terminal to successfully send an SRS <= the delay of the location service. For another example: the C-LBT time required for the wireless access network device to successfully send the first configuration information to the terminal <= the delay of the location service.

[0132] Since the third consecutive LBT time is less than or equal to the delay of the location service, or the fourth consecutive LBT time is less than or equal to the delay of the location service, it can be achieved that LBT is executed in advance based on the delay of the location service, so that the sending of positioning measurements can meet the delay of the location service to improve the positioning performance.

[0133] The above implementation manner may be applied to uplink positioning measurement, downlink positioning measurement or SL positioning measurement.

[0134] As an optional implementation manner, the first device acquires first configuration information of a reference signal for positioning measurement, including:

[0135] The first device obtains first configuration information of a reference signal for positioning measurement in an authorized frequency band.

[0136] The first device acquiring the first configuration information of the reference signal for positioning measurement in the authorized frequency band may be receiving the first configuration information of the reference signal for positioning measurement sent by other devices in the authorized frequency band.

[0137] In this implementation, since the first configuration information of the reference signal used for positioning measurement is obtained in the authorized frequency band, LBT can be reduced, thereby reducing the probability that the positioning delay exceeds the requirement.

[0138] In this implementation, it can be applied to uplink positioning measurement, downlink positioning measurement, or SL positioning measurement.

[0141] The first configuration information may be that after the wireless access network device receives the second configuration information of the reference signal sent by the core network element, the first configuration information is determined based on the second configuration information and then sent to the terminal.

[0142] In this implementation, the terminal can obtain the first configuration information from the wireless access network device.

[0143] The above implementation can be applied to uplink positioning measurement or SL positioning measurement.

[0144] In some implementations, for uplink positioning measurement or SL positioning measurement, the terminal may also obtain the first configuration information from a core network element.

[0145] As an optional implementation manner, when the first device is a wireless access network device, the method further includes:

[0150] The determining of the first configuration information based on the second configuration information may be to determine the first configuration information based on the second configuration information, or to determine the first configuration information based on the second configuration information as a reference.

[0151] In this implementation, the first device itself can determine the first configuration information, so that the first device can send the reference signal more flexibly.

[0152] In some implementations, after the first device determines the first configuration information, the first device may also send the first configuration information to a core network element, and the core network element sends the first configuration information to the terminal, so that the terminal performs positioning measurement based on the first configuration information.

[0165] Among them, the content indicated by the frequency indication information of the above-mentioned reference signal can refer to the content indicated by the frequency-related information of the reference signal of the reference signal in the above-mentioned implementation method, which is not described here. For example: the frequency band of the first reference signal of the periodic reference signal is the authorized frequency band, and the frequency bands of the remaining reference signals of the periodic reference signal are unauthorized frequency bands.

[0167] In a case where the frequency indication information of the reference signal is non-mandatory, the first device determines frequency-related information of the reference signal with reference to the frequency indication information of the reference signal.

[0168] The mandatory or non-mandatory nature may be indicated in the second configuration information, or may be agreed upon in a protocol or pre-configured.

[0169] The frequency indication information of the reference signal is mandatory, indicating that the first device needs to configure the frequency-related information of the reference signal according to the frequency indication information of the reference signal, such as using the frequency indication information of the reference signal as the frequency-related information of the reference signal.

[0170] The frequency indication information of the above-mentioned reference signal is non-mandatory, indicating that the first device can refer to part or all of the frequency indication information of the above-mentioned reference signal to configure the frequency-related information of the reference signal, which can be modified or not modified by the first device to obtain the above-mentioned first configuration information, which can be specifically determined by the implementation of the first device.

[0176] The first device performs an indication of LBT in advance.

[0177] The relationship between the delay of the location service and the delay of the LBT and the location service is described in the corresponding description of the above-mentioned implementation mode and is not repeated here. For example, the relationship between the delay of the LBT and the location service includes the following items:

[0178] The sum of the fifth continuous LBT time and the sixth continuous LBT time is less than or equal to the delay of the location service;

[0179] The fifth continuous LBT time is less than or equal to the delay of the location service;

[0180] The sixth continuous LBT time is less than or equal to the delay of the location service;

[0182] The multiple sets of unlicensed frequency band configurations of the reference signal may enable the first device to send the reference signal in multiple sets of configurations, so that the reference signal can be sent in a timely manner.

[0183] The indication that the first device performs LBT in advance may indicate that the first device needs to perform LBT in advance before sending the reference signal, wherein the specific time for performing LBT in advance is related to the configuration of LBT, for example, the time corresponding to the time domain of the PRS resource is minus the time of 1 LBT, and the time corresponding to the time domain of the SRS resource is minus the time of C LBT.

Figure 2 or Figure 3To avoid repeated description, the related description of the embodiment shown in the present invention will not be repeated in detail.

[0319] The method provided in the embodiments of the present application is illustrated below by means of multiple embodiments:

[0320] Embodiment 1:

[0321] This embodiment mainly describes the unlicensed frequency band uplink positioning, such as Figure 5 As shown, the following steps are included:

[0322] Step 1: AMF receives a location service request message (such as Location service request), which comes from the 5G core network (5GC) location service (LCS) entity, such as a mobile terminal location request (Mobile Terminated Location Request, MT-LR) from a 5GC LCS entity, a terminal originated location request (Mobile Originated Location Request, MO-LR) from a terminal, or a network triggered location request (Network Induced Location Request, NI-LR) from a serving AMF (Serving AMF).

[0323] The location service request message may include relevant information of the location service, and the relevant information of the location service includes at least one of the following: period requirement, accuracy requirement, and delay requirement;

[0324] The delay is the difference between the actual positioning time and the expected positioning time. For example, if the positioning period is 20 seconds, the terminal should be positioned in 20 seconds, 40 seconds, etc. However, the terminal competes for the channel in 21 seconds and completes the positioning in 22 seconds. In this case, the positioning delay is 2 seconds.

[0325] Step 2: AMF sends the location service request message received in step 1 to LMF.

[0326] Step 3: TRP Information Exchange process, LMF requests the NG-RAN node to provide specific information of TRP, such as whether unauthorized positioning is supported.

[0327] Step 4: LTE Positioning Protocol (LPP) capability transmission process, LMF requests and obtains the terminal's capability information.

[0328] Among them, the capability information of the above-mentioned terminal may include capability information related to unlicensed frequency band positioning, such as whether NR unlicensed (NR Unlicensed, NR-U) positioning is supported, and whether sidelink unlicensed (SL Unlicensed, SL-U) positioning is supported.

[0329] The frequency band resources used in the above LPP capability transfer process may be unlicensed frequency band resources or licensed frequency band resources.

[0330] Step 5: LMF determines the positioning method based on the received information.

[0331] The received information includes at least one of the following:

[0332] Relevant information of the location service in step 1;

[0333] Information in the base station response message received in step 3;

[0334] The terminal capability information received in step 4.

[0335] The specific determination criteria for the above-mentioned positioning method include at least one of the following:

[0336] The bandwidth of the uplink positioning reference signal in the licensed frequency band supported by the terminal capability cannot meet the positioning accuracy requirement, while the bandwidth of the uplink positioning reference signal in the unlicensed frequency band supported by the terminal capability can meet the positioning accuracy requirement. The unlicensed frequency band positioning can be selected;

[0337] If the frequency bandwidth of the cell in the licensed frequency band does not meet the positioning accuracy requirements, unlicensed frequency band positioning is used;

[0338] If the unlicensed frequency band positioning takes precedence over the licensed frequency band positioning, then the unlicensed frequency band positioning shall prevail;

[0339] If the terminal has the capability of unlicensed frequency band positioning, the positioning method is unlicensed frequency band positioning;

[0340] If the terminal has the capability of unlicensed frequency band positioning, and the period of the location service and the delay requirement of the location service are greater than a threshold, the positioning method is unlicensed frequency band positioning.

[0341] Step 6: LMF sends a positioning information request (POSITIONING INFORMATION REQUEST) message to the base station.

[0342] The POSITIONING INFORMATION REQUEST message includes at least one of the following:

[0343] Frequency indication information of SRS;

[0344] Auxiliary information when SRS is in unlicensed frequency band;

[0345] Location service related information (i.e. the corresponding content in step 1);

[0346] Terminal capability information (e.g., terminal unlicensed frequency band positioning capability);

[0347] The time information of the positioning result needs to be obtained. For example, in step 1, the time when the 5GC LCS entity or terminal or service AMF initiates the location service request is 10:00:00. Then the time information of the positioning result needs to be obtained is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which are periodic positioning every 15 seconds, plus the optional indication of early execution of LBT (for example, the positioning result of 10:00:15, the UE performed LBT at 10:00:05, such as completing LBT in the positioning preparation phase);

[0348] The time when SRS is completed to be sent;

[0349] Time of completion of LBT;

[0350] Advance LBT Instructions

[0351] In the above steps, the time information of the positioning result that needs to be obtained is generated by the LMF or the base station. Through the above steps, the LBT can be executed in advance.

[0352] The specific content of the SRS frequency indication information includes at least one of the following:

[0353] The periodic SRS is all in the licensed frequency band;

[0354] All periodic SRS are in unlicensed frequency bands;

[0355] SRS transmission bandwidth associated with frequency information;

[0356] Part of the periodic SRS is the authorized frequency band, and part is the unlicensed frequency band. For example, odd-numbered SRS is the authorized frequency band, and even-numbered SRS is the unlicensed frequency band. This can reduce the chances of needing to do LBT. For example, the base station can configure multiple sets of SRS configurations to achieve part of the periodic SRS being the authorized frequency band and part of the unlicensed frequency band.

[0357] The frequency band of the first SRS of the periodic SRS is the authorized frequency band. Because step 1 is the positioning of the non-scheduled location time, the first SRS of the periodic SRS is preferably in the authorized frequency band, so that the positioning result can be returned to the client as quickly as possible. The positioning results corresponding to other periodic SRSs can be similar to the scheduled location time positioning. LBT can be executed in advance in the positioning preparation stage, so the unlicensed frequency band can be used. Specifically, the base station can configure multiple sets of SRS configurations to achieve the first SRS of the periodic SRS as the unlicensed frequency band and the others as the authorized frequency band;

[0358] The base station sends SRS configuration to the terminal using the authorized frequency band, which can reduce the chance of needing to do LBT;

[0359] Through the above content, the terminal can perform authorized spectrum positioning and unlicensed spectrum positioning at the same time, so as to ensure the delay. The first SRS may only be available in the authorized frequency band, but the subsequent SRS is equivalent to the SRS of scheduled location time, so the delay can be guaranteed by executing LBT in advance.

[0360] The positioning of Scheduled Location Time may be as follows:

[0361] The scheduled location time allows an external LCS client, AF or terminal to specify a time in the future to obtain the current location of the terminal. The scheduled location time can be used with 5GC-MT-LR, 5GC-MO-LR or delayed 5GC-MT-LR for periodic or triggered location events. The location preparation phase begins when the LCS client, AF or UE requests the current location of the UE. The request includes the scheduled positioning time t. As part of the positioning preparation phase, the 5GC and the terminal interact to determine the appropriate positioning method and plan the UE's location measurement. The LMF coordinates the interaction and is aware of the scheduled location time. The location preparation phase ends at or near time T, followed by the location execution phase, during which the terminal location is obtained and returned to the external LCS client, AF or terminal.

[0362] The characteristics of the frequency indication information of the SRS are at least one of the following:

[0363] Mandatory, that is, the base station needs to follow the instructions of the LMF;

[0364] Preference, that is, LMF only gives the base station a preference, and the base station only uses this indication information as a reference. The final frequency of SRS is determined by the base station.

[0365] The auxiliary information when the SRS is in an unlicensed frequency band includes at least one of the following:

[0366] The setting of LBT needs to consider the delay of location services (for example, the C-LBT time required for the base station to send SRS configuration to the UE + the C-LBT time required for the UE to successfully send an SRS <= the delay of location services, for example, the C-LBT time required for the UE to successfully send an SRS <= the delay of location services, for example, the C-LBT time required for the base station to successfully send SRS configuration to the UE <= the delay of location services);

[0367] Configure multiple SRS configurations. The advantage of this is that if the terminal fails LBT on one SRS configuration, it will immediately switch to another SRS configuration to try LBT, instead of trying LBT a second time on the SRS configuration until C-LBT fails.

[0368] Part or all of the resources of the periodic SRS are time-frequency domain resources shared by the channel occupancy time (COT). The time-frequency domain resources of the cot sharing may be resources shared after the LBT is successful in the unlicensed frequency band when the base station sends the SRS configuration to the UE, such as sharing the resources with the UE after the LBT is successful, or the time-frequency domain resources of the cot sharing may be resources shared by the UE after the LBT is successful in the unlicensed frequency band when the UE sends the SRS.

[0369] Step 7a: After receiving the positioning information request (POSITIONING INFORMATION REQUEST) message sent by the LMF, the base station determines the SRS configuration.

[0370] The method for determining the SRS configuration is at least one of the following:

[0371] When the frequency indication information of the SRS is mandatory, configure the SRS according to the content in the POSITIONING INFORMATION REQUEST message;

[0372] When the frequency indication information of the SRS is non-mandatory, the SRS may be configured by referring to part or all of the content in the POSITIONING INFORMATION REQUEST message.

[0373] The SRS configuration is at least one of the following:

[0374] Information related to the frequency of the SRS;

[0375] When the SRS is an unlicensed frequency band, the configuration information related to the unlicensed frequency band;

[0376] The time information of the positioning result needs to be obtained (for example, the time when the 5GC LCS entity or UE or ServingAMF initiates the location service request in step 1 is 10:00:00, then the time information of the positioning result needs to be obtained is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which are periodic positioning every 15 seconds), plus an optional indication of early execution of LBT (for example, the positioning result at 10:00:15, the UE performed LBT at 10:00:05, such as completing LBT in the positioning preparation phase).

[0377] The time information required to obtain the positioning result may be that the base station needs to send delay-related information to the UE so that the UE performs LBT in advance. It may be an indication or a specific time.

[0378] The specific content of the relevant information of the SRS frequency includes at least one of the following:

[0379] The periodic SRS is all in the licensed frequency band;

[0380] All periodic SRS are in unlicensed frequency bands;

[0381] SRS transmission bandwidth associated with frequency information;

[0382] Part of the periodic SRS is the licensed frequency band, and part is the unlicensed frequency band. For example, the odd-numbered SRS is the licensed frequency band, and the even-numbered SRS is the unlicensed frequency band. This can reduce the chances of needing to do LBT.

[0383] The frequency band of the first SRS of the periodic SRS is the authorized frequency band (because step 1 is the positioning of unscheduled location time, the first SRS of the periodic SRS is preferably in the authorized frequency band, so that the positioning result can be returned to the client as quickly as possible. The positioning results corresponding to other periodic SRS can be similar to scheduled location time positioning. LBT can be executed in advance in the positioning preparation stage, so the unlicensed frequency band can be used);

[0384] The base station sends SRS configuration to the UE using the licensed frequency band, which can reduce the chance of needing to do LBT;

[0385] For SRS in unlicensed frequency bands, multiple sets of unlicensed frequency band resources are configured for the SRS. The advantage of this is that if the terminal fails to perform LBT in one SRS configuration, it will immediately switch to another SRS configuration to try LBT, instead of performing a second LBT attempt on the SRS configuration until C-LBT fails.

[0386] For SRS in unlicensed frequency bands, its resources are time-frequency domain resources of cot sharing.

[0387] The configuration information related to the above unlicensed frequency band includes:

[0388] The setting of LBT takes into account the delay of location services (for example, the C-LBT time required for the base station to send the SRS configuration to the UE + the C-LBT time required for the UE to successfully send an SRS <= the delay of location services, for example, the C-LBT time required for the UE to successfully send an SRS <= the delay of location services, for example, the C-LBT time required for the base station to successfully send the SRS configuration to the UE <= the delay of location services).

[0389] Step 7b: The base station sends the SRS configuration to the UE. After the UE receives the SRS configuration sent by the base station, it sends the SRS according to the specific content of the received SRS configuration.

[0390] The above-mentioned sending of SRS according to the specific content in the received SRS configuration may be:

[0391] When the SRS configuration includes the time information for obtaining the positioning result and the indication of early execution of Optional LBT, the UE executes LBT in advance before the time for obtaining the positioning result. The specific time for early execution of LBT is related to the configuration of LBT, for example, the time corresponding to the time domain of the SRS resource minus the time of 1 LBT, and the time corresponding to the time domain of the SRS resource minus the time of C LBT.

[0392] Step 7c: The base station sends a POSITIONING INFORMATION RESPONSE message to the LMF, which includes the SRS configuration. The LMF performs corresponding operations according to the specific content of the received SRS configuration.

[0393] The above-mentioned corresponding operation performed according to the specific content in the received SRS configuration may be:

[0394] When the SRS configuration includes information on the time when the positioning result needs to be obtained, the LMF performs the positioning preparation phase in advance before the time when the positioning result needs to be obtained, such as executing step 8 in advance.

[0395] There is no clear order between the above steps 7b and 7c, which depends on the base station implementation.

[0396] Step 8: LMF sends the SRS configuration to the relevant base station through the NR positioning protocol A (NRPPa) message, such as sending it to the relevant base station through a measurement request (MEASUREMENT REQUEST), and requests the relevant base station to perform SRS measurement based on the configuration;

[0397] Step 9: The relevant base station performs UL SRS measurement based on the configuration

[0398] Step 10: The relevant base station feeds back the SRS measurement result via an NRPPa message (eg, Measurement Response).

[0399] Embodiment 2

[0400] This embodiment mainly describes the downlink positioning of the unlicensed frequency band. Figure 6 As shown, the following steps are included:

[0401] Step 1: AMF receives a location service request message (Location service request), which comes from one of the MT-LR of the 5GC LCS entity, the MO-LR of the UE, and the NI-LR of the Serving AMF.

[0402] The location service request information may include relevant information of the location service, such as period requirements, accuracy requirements, latency requirements, low power high accuracy positioning (LPHAP) and the like of the location service.

[0403] Step 2: AMF sends the location service request message received in step 1 to LMF.

[0404] Step 3: LPP capability transfer process, LMF requests and obtains UE capability information.

[0405] Among them, the capability information of the above-mentioned UE 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.

[0406] The frequency band resources used in the LPP capability transfer process may be unlicensed frequency band resources or licensed frequency band resources.

[0407] Step 4: LMF determines the positioning method based on the received information.

[0408] The received information includes at least one of the following:

[0409] Relevant information of the location service in step 1;

[0410] The UE capability information received in step 3.

[0411] The specific determination criteria for the above-mentioned positioning method include at least one of the following:

[0412] The bandwidth of the uplink positioning reference signal in the licensed frequency band supported by the terminal capability cannot meet the positioning accuracy requirement, while the bandwidth of the uplink positioning reference signal in the unlicensed frequency band supported by the terminal capability can meet the positioning accuracy requirement. The unlicensed frequency band positioning can be selected;

[0413] If the unlicensed frequency band positioning takes precedence over the licensed frequency band positioning, then the unlicensed frequency band positioning shall prevail;

[0414] If the UE has the unlicensed frequency band positioning capability, the positioning method is unlicensed frequency band positioning;

[0415] If the UE has the capability of unlicensed frequency band positioning, and the period of the location service and the delay requirement of the location service are greater than a threshold, the positioning method is unlicensed frequency band positioning.

[0416] Step 5: LMF sends the first NRPPa message to the base station.

[0417] Among them, the above-mentioned first NRPPa message can be a TRP information request (TRP Information Request) message or a positioning reference signal (Positioning Reference Signal, PRS) configuration request message.

[0418] The first NRPPa message includes at least one of the following:

[0419] Frequency indication information of PRS;

[0420] Auxiliary information when PRS is in unlicensed frequency band;

[0421] Relevant information of the location service, i.e., the corresponding content in step 1;

[0422] Terminal capability information, such as the terminal's unlicensed frequency band positioning capability;

[0423] The time information of the positioning result needs to be obtained (for example, the time when the 5GC LCS entity or UE or ServingAMF initiates the location service request in step 1 is 10:00:00, then the time information of the positioning result needs to be obtained is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which are periodic positioning every 15 seconds), plus an optional indication of early execution of LBT (for example, the positioning result at 10:00:15, LBT was performed at 10:00:05, such as LBT was completed in the positioning preparation stage).

[0424] The specific content of the frequency indication information of the PRS includes at least one of the following:

[0425] The periodic PRS are all in the licensed band;

[0426] The periodic PRS are all in unlicensed bands;

[0427] PRS transmission bandwidth associated with frequency information;

[0428] Part of the periodic PRS is the licensed frequency band, and part is the unlicensed frequency band. For example, the odd-numbered PRS is the licensed frequency band, and the even-numbered PRS is the unlicensed frequency band. This can reduce the chances of needing to do LBT.

[0429] The frequency band of the first PRS of the periodic PRS is the authorized frequency band. Since step 1 is the positioning of the unscheduled location time, the first PRS of the periodic PRS is preferably in the authorized frequency band, so that the positioning result can be returned to the client as quickly as possible. The positioning results corresponding to other periodic PRSs can be similar to the scheduled location time positioning. LBT can be executed in advance in the positioning preparation stage, so the unlicensed frequency band can be used;

[0430] LMF sends PRS configuration to UE using the licensed frequency band, which can reduce the chance of needing to do LBT.

[0431] The characteristics of the frequency indication information of the PRS are at least one of the following:

[0432] Mandatory, that is, the base station needs to follow the instructions of the LMF;

[0433] It is non-mandatory, that is, LMF only gives the base station a tendency, and the base station only uses this indication information as a reference. The final frequency of PRS is determined by the base station.

[0434] The auxiliary information when the PRS is an unlicensed frequency band includes at least one of the following:

[0435] The setting of LBT needs to consider the delay of location services (for example, the C-LBT time required for LMF to send PRS configuration to UE + the C-LBT time required for the base station to successfully send PRS once <= the delay of location services, for example, the C-LBT time required for the base station to successfully send PRS once <= the delay of location services, for example, the C-LBT time required for LMF to successfully send PRS configuration to UE <= the delay of location services);

[0436] Configure multiple PRS configurations. The advantage of this is that if the base station fails LBT on one PRS configuration, it will immediately switch to another PRS configuration to try LBT, rather than making a second LBT attempt on the same PRS configuration until C-LBT fails.

[0437] Before sending PRS, the base station needs to perform LBT in advance. The specific time of performing LBT in advance is related to the configuration of LBT, for example, the time corresponding to the time domain of PRS resources is - the time of 1 LBT, and the time corresponding to the time domain of SRS resources is - the time of C LBT.

[0438] Step 6: After receiving the first NRPPa message sent by LMF, the base station determines the PRS configuration and feeds back the PRS configuration to LMF through the second NRPPa message.

[0439] Among them, the above-mentioned second NRPPa message can be a TRP information response message or a positioning reference signal PRS configuration response message.

[0440] The method for determining the PRS configuration is at least one of the following:

[0441] When the frequency indication information of the PRS is mandatory, configure the PRS according to the content in the TRP INFORMATION REQUEST message;

[0442] When the frequency indication information of the PRS is a preference, the PRS may be configured by referring to part or all of the content in the TRP INFORMATION REQUEST message.

[0443] The PRS configuration includes at least one of the following:

[0444] Information about the frequency of the PRS;

[0445] When the PRS is an unlicensed frequency band, the configuration information related to the unlicensed frequency band;

[0446] The time information of the positioning result needs to be obtained (for example, the time when the 5GC LCS entity or UE or ServingAMF initiates the location service request in step 1 is 10:00:00, then the time information of the positioning result needs to be obtained is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which are periodic positioning every 15 seconds), plus the optional indication of early execution of LBT. For example, the positioning result of 10:00:15, the UE performed LBT at 10:00:05, such as completing LBT in the positioning preparation phase.

[0447] The specific content of the relevant information of the PRS frequency includes at least one of the following:

[0448] The periodic PRS are all in the licensed band;

[0449] The periodic PRS are all in unlicensed bands;

[0450] PRS transmission bandwidth associated with frequency information;

[0451] Part of the periodic PRS is the licensed frequency band, and part is the unlicensed frequency band. For example, the odd-numbered PRS is the licensed frequency band, and the even-numbered PRS is the unlicensed frequency band. This can reduce the chances of needing to do LBT.

[0452] The frequency band of the first PRS of the periodic PRS is the authorized frequency band. Because step 1 is the positioning of unscheduled location time, the first PRS of the periodic PRS is preferably in the authorized frequency band, so that the positioning result can be returned to the client as quickly as possible. The positioning results corresponding to other periodic PRSs can be similar to scheduled location time positioning. LBT can be executed in advance in the positioning preparation stage, so the unlicensed frequency band can be used;

[0453] LMF sends PRS configuration to the terminal using the licensed frequency band, which can reduce the chance of needing to do LBT;

[0454] For PRS in unlicensed frequency bands, multiple sets of unlicensed frequency band resources are configured for the PRS. The advantage of this is that if the base station fails to perform LBT in one set of PRS configurations, it will immediately switch to other PRS configurations to try LBT, rather than making a second LBT attempt on the current set of PRS configurations until C-LBT fails.

[0455] The configuration information related to the unlicensed frequency band includes at least one of the following:

[0456] The setting of LBT takes into account the latency of location services. For example, the C-LBT time required for LMF to send PRS configuration to UE + the C-LBT time required for the base station to successfully send PRS once <= the latency of location services. For example, the C-LBT time required for the base station to successfully send PRS once <= the latency of location services. For example, the C-LBT time required for LMF to successfully send PRS configuration to UE <= the latency of location services.

[0457] Before sending PRS, the base station will perform LBT in advance. The specific time of performing LBT in advance is related to the configuration of LBT, for example, the time corresponding to the time domain of PRS resources is - the time of 1 LBT, and the time corresponding to the time domain of SRS resources is - the time of C LBT.

[0458] Step 7-8: After LMF receives the message in step 6, LMF performs corresponding operations according to the specific content in the received PRS configuration.

[0459] The above-mentioned performing corresponding operations according to the specific content in the received PRS configuration may be:

[0460] When the above PRS configuration contains information on the time when the positioning result needs to be obtained, the LMF performs the positioning preparation phase in advance before the time when the positioning result needs to be obtained, such as executing steps 7 and 8 in advance.

[0461] Step 7: LMF provides LPP assistance data to the UE.

[0462] Step 8: LMF sends LPP request positioning information to UE, and UE performs DL PRS measurement.

[0463] Step 9: UE provides LPP positioning information to LMF.

[0464] Embodiment three:

[0465] This embodiment mainly describes the downlink positioning of the unlicensed frequency band. Figure 7 As shown, the following steps are included:

[0466] Step 1: The application in the terminal has a demand for location services, and the terminal determines the positioning method.

[0467] The location service requirement may include relevant information of the location service, and the relevant information of the location service may include at least one of the following:

[0468] Cycle requirements, accuracy requirements, and delay requirements.

[0469] The specific determination criteria for the above-mentioned positioning method include at least one of the following:

[0470] The bandwidth of the uplink positioning reference signal in the licensed frequency band supported by the terminal capability cannot meet the positioning accuracy requirement, while the bandwidth of the uplink positioning reference signal in the unlicensed frequency band supported by the terminal capability can meet the positioning accuracy requirement. The unlicensed frequency band positioning can be selected;

[0471] If the unlicensed frequency band positioning takes precedence over the licensed frequency band positioning, then the unlicensed frequency band positioning shall prevail;

[0472] If the terminal has the capability of unlicensed frequency band positioning, the positioning method is unlicensed frequency band positioning;

[0473] If the terminal has the capability of unlicensed frequency band positioning, and the period of the location service and the delay requirement of the location service are greater than a threshold, the positioning method is unlicensed frequency band positioning.

[0474] Step 2: The terminal sends a Request Assistance Data message to the LMF.

[0475] The Request Assistance Data message includes at least one of the following:

[0476] Frequency indication information of PRS;

[0477] Auxiliary information when PRS is in unlicensed frequency band;

[0478] Relevant information of the location service, i.e., the corresponding content in step 1;

[0479] UE capability information, such as UE unlicensed band positioning capability;

[0480] The time information of the positioning result needs to be obtained (for example, the time when the 5GC LCS entity or UE or ServingAMF initiates the location service request in step 1 is 10:00:00, then the time information of the positioning result needs to be obtained is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which are periodic positioning every 15 seconds), plus the optional indication of early execution of LBT, for example, the positioning result of 10:00:15, LBT was performed at 10:00:05, such as completing LBT in the positioning preparation phase;

[0481] The specific content of the frequency indication information of the PRS includes at least one of the following:

[0482] The periodic PRS are all in the licensed band;

[0483] The periodic PRS are all in unlicensed bands;

[0484] PRS transmission bandwidth associated with frequency information;

[0485] Part of the periodic PRS is the licensed frequency band, and part is the unlicensed frequency band. For example, the odd-numbered PRS is the licensed frequency band, and the even-numbered PRS is the unlicensed frequency band. This can reduce the chances of needing to do LBT.

[0486] The frequency band of the first PRS of the periodic PRS is the authorized frequency band. Because step 1 is the positioning of unscheduled location time, the first PRS of the periodic PRS is preferably in the authorized frequency band, so that the positioning result can be returned to the client as quickly as possible. The positioning results corresponding to other periodic PRSs can be similar to scheduled location time positioning. LBT can be executed in advance in the positioning preparation stage, so the unlicensed frequency band can be used;

[0487] LMF sends PRS configuration to UE using the licensed frequency band, which can reduce the chance of needing to do LBT.

[0488] The characteristics of the frequency indication information of the PRS are at least one of the following:

[0489] Mandatory, that is, the base station needs to execute according to the instructions of the terminal;

[0490] It is non-mandatory, that is, the terminal only gives the base station a preference, and the base station only uses this indication information as a reference. The final frequency of the PRS is determined by the base station.

[0491] The auxiliary information when the PRS is an unlicensed frequency band includes at least one of the following:

[0492] The setting of LBT needs to consider the delay of location services. For example, the C-LBT time required for LMF to send PRS configuration to UE + the C-LBT time required for the base station to successfully send PRS once <= the delay of location services. For example, the C-LBT time required for the base station to successfully send PRS once <= the delay of location services. For example, the C-LBT time required for LMF to successfully send PRS configuration to UE <= the delay of location services.

[0493] Configure multiple PRS configurations. The advantage of this is that if the base station fails LBT on one PRS configuration, it will immediately switch to another PRS configuration to try LBT, rather than making a second LBT attempt on the same PRS configuration until C-LBT fails.

[0494] Before sending PRS, the base station needs to perform LBT in advance. The specific time of performing LBT in advance is related to the configuration of LBT, for example, the time corresponding to the time domain of PRS resources is - the time of 1 LBT, and the time corresponding to the time domain of SRS resources is - the time of C LBT.

[0495] Step 3-4: After receiving the message sent by the terminal, the LMF determines the PRS configuration and feeds back the content of the Request Assistance Data message to the base station through the first NRPPa message. The base station determines the PRS configuration and sends the PRS configuration to the LMF through the second NRPPa message.

[0496] The method for determining the PRS configuration is at least one of the following:

[0497] When the frequency indication information of the PRS is mandatory, the PRS is configured according to the content in the TRP INFORMATION REQUEST message;

[0498] When the frequency indication information of the PRS is a preference, the PRS may be configured by referring to part or all of the content in the TRP INFORMATION REQUEST message.

[0499] The PRS configuration includes at least one of the following:

[0500] Information about the frequency of the PRS;

[0501] When the PRS is an unlicensed frequency band, the configuration information related to the unlicensed frequency band;

[0502] The time information of the positioning result needs to be obtained (for example, the time when the 5GC LCS entity or terminal or service AMF initiates the location service request in step 1 is 10:00:00, then the time information of the positioning result needs to be obtained is 10:00:00, 10:00:15, 10:00:30, 10:00:45, 10:01:00, etc., which are periodic positioning every 15 seconds), plus the Optional LBT early execution indication, for example, the positioning result of 10:00:15, LBT was performed at 10:00:05, such as LBT was completed in the positioning preparation stage.

[0503] The specific content of the relevant information of the PRS frequency includes at least one of the following:

[0504] The periodic PRS are all in the licensed band;

[0505] The periodic PRS are all in unlicensed bands;

[0506] PRS transmission bandwidth associated with frequency information;

[0507] Part of the periodic PRS is the licensed frequency band, and part is the unlicensed frequency band. For example, the odd-numbered PRS is the licensed frequency band, and the even-numbered PRS is the unlicensed frequency band. This can reduce the chances of needing to do LBT.

[0508] The frequency band of the first PRS of the periodic PRS is the authorized frequency band (because step 1 is the positioning of unscheduled location time, the first PRS of the periodic PRS is preferably in the authorized frequency band, so that the positioning result can be returned to the client as quickly as possible. The positioning results corresponding to other periodic PRSs can be similar to scheduled location time positioning. LBT can be executed in advance in the positioning preparation stage, so the unlicensed frequency band can be used);

[0509] LMF sends PRS configuration to UE using the licensed frequency band, which can reduce the chance of needing to do LBT;

[0510] For PRS in unlicensed frequency bands, multiple sets of unlicensed frequency band resources are configured for the PRS. The advantage of this is that if the base station fails to perform LBT in one set of PRS configurations, it will immediately switch to other PRS configurations to try LBT, rather than making a second LBT attempt on the current set of PRS configurations until C-LBT fails.

[0511] The configuration information related to the unlicensed frequency band includes at least one of the following:

[0512] The setting of LBT takes into account the latency of location services. For example, the C-LBT time required for LMF to send PRS configuration to UE + the C-LBT time required for the base station to successfully send PRS once <= the latency of location services. For example, the C-LBT time required for the base station to successfully send PRS once <= the latency of location services. For example, the C-LBT time required for LMF to successfully send PRS configuration to UE <= the latency of location services.

[0513] Before sending PRS, the base station will perform LBT in advance. The specific time of performing LBT in advance is related to the configuration of LBT. For example, the time corresponding to the time domain of PRS resources is reduced by 1 LBT time, and the time corresponding to the time domain of SRS resources is reduced by C LBT times.
