Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a PRS measurement method, device, terminal, and medium. Background Technology

[0002] Currently, terminals can perform location tracking by receiving PRS (Personal Signal Response) sent by the network side.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to applications other than NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0029] Figure 1 This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home device (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, game consoles, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment.

The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, transmitting and receiving point (TRP), or any other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that this application embodiment only uses a base station in an NR system as an example, but does not limit the specific type of base station.

[0030] In related technologies, different PRSs may be transmitted under the same positioning scenario. For example, a PRS that can be transmitted under any circumstances (e.g., the PRS introduced in Release 16) will not change its configuration within a certain area. Alternatively, an on-demand PRS introduced in Release 17 will have its corresponding configuration (e.g., positioning assistance data) change. Specifically, the configuration information of the Release 16 PRS is determined by the gNB / TRP or during network installation, and the LMF or UE cannot change or adjust the PRS configuration as needed. However, the PRS introduced in Release 17 is transmitted on demand, therefore its corresponding configuration (e.g., positioning assistance data) will change.

[0031] Thus, since different PRS may exist in a single location session, the terminal cannot distinguish whether the current PRS configuration has changed, leading to location failure.

[0032] To address the aforementioned issues, the PRS measurement method, apparatus, terminal, and medium provided in this application embodiment allow the terminal, upon receiving a first PRS and / or a second PRS, to measure the target PRS (the first PRS and / or the second PRS) and / or report first information related to the target PRS (at least one of the terminal's location information and the target PRS's measurement information) based on target information. In this way, the terminal determines the target PRS that needs to be measured based on the target information, enabling the terminal to clearly understand its own measurement behavior, achieving terminal positioning, and improving the system's communication efficiency.

[0033] The measurement method of PRS provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0034] This application provides a method for measuring PRS, such as... Figure 2 As shown, the PRS measurement method provided in this application embodiment includes the following steps:

[0035] Step 201: The terminal receives the first PRS and / or the second PRS.

[0036] Step 202: The terminal measures the target PRS and / or reports the first information related to the target PRS based on the target information.

[0037] Among them, the aforementioned target PRS includes at least one of the following: first PRS, second PRS.

[0038] In this embodiment, the first PRS can be an on-demand PRS, and the second PRS can be a regular PRS (e.g., a PRS supported by NR Rel 16). In other words, the first and second PRS can be considered as different types of PRS. It can also be understood that the PRS are PRS with different configuration methods; that is, the first PRS (on-demand PRS) is configured according to the request or requirement of the UE or LMF, while the second PRS does not involve this process. Furthermore, it can be understood that the PRS are PRS with different configurations. For example, the PRS configurations (such as bandwidth, beamwidth, period, time-frequency position, etc.) of the first and second PRS are different, or the first PRS requires activation information to activate.

[0039] For example, the first PRS mentioned above can be a PRS introduced in R17, and the second PRS mentioned above can be a PRS introduced in R16.

[0040] For example, the terminal may not know whether the PRS is the first PRS or the second PRS.

[0041] For example, the terminal cannot distinguish between the first PRS and the second PRS.

[0042] In this embodiment of the application, the first information mentioned above includes at least one of the following: the location information of the terminal, and the measurement information of the target PRS.

[0043] Combination Figure 2 ,like Figure 3 As shown in the embodiment of this application, another method for measuring PRS includes the following steps:

The aforementioned target PRS type information, and / or target PRS identification information, is used to distinguish which PRS or which PRS the location information of the aforementioned terminal and / or the measurement information of the target PRS comes from.

[0056] For example, the location assistance data identifier can be nr-DL-PRS-AssistanceData-r17 or nr-DL-PRS-AssistanceData-r16.

[0057] For example, location assistance data is identified as information associated with the target PRS.

[0058] For example, the type information of the target PRS includes type 1 and / or type 2, where type 1 is associated with a first PRS and type 2 is associated with a second PRS.

[0059] For example, the location information of the terminal mentioned above includes: the type information of the target PRS, and / or the identification information of the target PRS.

The first positioning assistance data includes the first PRS; the second positioning assistance data does not include the first PRS but includes the second PRS.

The second configuration information is used to configure at least one PRS.

[0084] For example, the aforementioned first positioning assistance data may contain only first configuration information, only second configuration information, or both first and second configuration information. Furthermore, when the aforementioned first positioning assistance data contains both first and second configuration information, the aforementioned first PRS may be one or more of the aforementioned at least one PRS.

[0085] For example, the aforementioned first positioning assistance data may include positioning assistance data containing second configuration information received before only the first configuration information is received. Furthermore, the positioning assistance data containing second configuration information may be received before or after the UE capability reporting.

[0086] For example, the second configuration information included in the aforementioned first positioning assistance data can be understood as pre-configuration information, which is used to configure multiple first PRSs. Here, a first PRS can be understood as a set of PRSs, including one or more PRSs. The first configuration information included in the aforementioned first positioning assistance data can be understood as activation information, which is used to activate one of the multiple first PRSs.

[0257] For example, the interval between the first information reports can be the time interval between two first information reports.

[0258] For example, the interval for reporting the first information can be the time interval between receiving the activation information and reporting the first information.

[0259] For example, the interval for reporting the first information can be the time interval between measuring the first slot of the PRS and reporting the first information.

[0260] For example, the interval for reporting the first information can be the time interval between the measurement window and the first information report.

[0261] For example, the QoS of the first information request includes at least one of the following:

For example, the parameter value of the target parameter in the second location request message is greater than the parameter value of the target parameter in the first location request message; or, the parameter value of the target parameter in the second location request message is less than the parameter value of the target parameter in the first location request message.

[0271] For example, the target parameters mentioned above include at least one of the following:

[0272] Event information that triggers the first information report.

[0273] The interval for reporting the first piece of information.

[0274] QoS for the first information request

[0275] The granularity factor of the first information in terms of time reporting.

[0276] Optionally, in this embodiment of the application, the location request corresponding to the first PRS includes at least one of the following:

[0277] First information;

[0278] Event information that triggers the location request corresponding to the first PRS.

[0279] Instructions to activate the first PRS.

[0281] Deactivate the time information of the first PRS.

[0285] Expected Angle of Arrival (AOA) information

[0286] First PRS measurement window information;

[0287] The aforementioned activation target PRS indication information is used to activate the target PRS;

[0288] The aforementioned time information includes at least one of the following: absolute time, time offset, and time domain location;

[0289] The measurement window information mentioned above includes at least one of the following: start time information, end time information, and measurement window length;

[0290] The second configuration information mentioned above is used to configure at least one PRS, and the first PRS mentioned above is one or more of the at least one PRS.

[0291] Optionally, in this embodiment of the application, the measurement information of the target PRS includes at least one of the following:

[0292] Measurement information of one or more first PRS,

[0293] Measurement information of one or more second PRS.

[0294] Optionally, in the embodiments of this application, the measurement information of the target PRS includes at least one of the following:

[0295] Identification information of the target PRS,

[0296] Measurement results of the target PRS,

[0297] Information about the type of target PRS

[0298] Location auxiliary data identifier,

[0299] Bandwidth information of the target PRS.

[0300] Aggregation indication information 1,

[0301] Aggregate indication information 2,

[0302] Among them, aggregation indication information 1 is used to indicate whether the target PRS is aggregated;

[0303] Aggregation indication information 2 is used to indicate whether the target PRS overlaps with the second PRS.

[0304] For example, if the terminal measures the first PRS and the second PRS respectively, the terminal can report the measurement results of the first PRS and the second PRS respectively. In one example, the measurement result of the first PRS includes a first PRS indication (e.g., an on-demand PRS indication). In another example, the measurement result of the second PRS includes a second PRS indication (e.g., an R16 PRS indication).

[0305] For example, a first PRS (with an 80MHz bandwidth) and a second positioning signal (with a 20MHz bandwidth) have identical resources on the 20MHz bandwidth as the first PRS. In one example, the measurement result of the first PRS may include a first PRS indication (e.g., an on-demand PRS indication), an aggregation indication, or a bandwidth indication. In another example, the measurement result of the second PRS may include a second PRS indication (e.g., an R16 PRS indication), a non-aggregation indication, or a bandwidth indication.

[0306] It should be noted that the PRS introduced in R16 and R17 are used by terminals. They may or may not overlap in time and / or frequency. A terminal can measure two PRSs (e.g., a terminal can measure a first PRS and a second PRS separately), and for both types of PRSs, the terminal reports the measurement results for both types of PRS separately or simultaneously. An example is that the PRS introduced in R16 covers 20 MHz, while the PRS introduced in R17 covers an adjacent 80 MHz bandwidth. The two PRSs completely overlap in time.

[0307] It should be noted that the process by which a terminal reports the measurement reports of the first PRS and the second PRS in one report can be called "aggregation".

[0308] Optionally, in the embodiments of this application, the above-mentioned predetermined rules include at least one of the following:

[0309] Rule 1a: If the priority of the first PRS is equal to the first predetermined priority threshold, or if the priority of the first PRS is greater than the second predetermined priority threshold, then only the first PRS is measured;

[0310] Rule 2a: If the priority of the first PRS is equal to the third predetermined priority threshold, or if the priority of the first PRS is less than or equal to the second predetermined priority threshold, then the target PRS is determined based on the priority of the first PRS and the priority of the second PRS.

[0311] Rule 3a: If the target information includes deactivation information of the first PRS, only the second PRS shall be measured;

[0312] Rule 4a: Measure PRS only within the measurement window of the first PRS;

[0313] Rule 5a: The first PRS is measured if the priority of the first PRS is greater than the second predetermined priority threshold, and / or the priority of the first PRS is greater than the priority of the second PRS.

[0314] Rule 6a: Measure the first PRS if there is a measurement indication information for the first PRS or if the priority of the first PRS is equal to the first predetermined priority threshold.

[0315] Optionally, in the embodiments of this application, the above-mentioned predetermined rules include at least one of the following:

[0316] Rule 1b: When a first PRS is configured, the terminal is not expected to receive a second PRS, and / or the first PRS covers the second PRS, and / or only the first PRS is measured;

[0317] Rule 2b: In the event of a conflict between the first PRS and the second PRS, the terminal cancels the transmission of the second PRS, and / or the terminal assumes that only the first PRS was transmitted, and / or the terminal only measures the first PRS;

[0318] Rule 2b: In the event of a conflict between the first PRS and the second PRS, the terminal cancels the transmission of the first PRS, and / or the terminal assumes that only the second PRS was transmitted, and / or the terminal only measures the second PRS;

[0319] Rule 3b: The terminal prioritizes measuring the first PRS;

[0320] Rule 4b: The terminal measures the first PRS and the second PRS respectively;

[0321] Rule 5b: Combine the first and second PRS for measurement;

[0322] Rule 6b: If there is an incomplete PRS measurement before receiving positioning assistance data, stop the PRS measurement and restart the PRS measurement based on the positioning assistance data, or continue the PRS measurement and perform the PRS measurement based on the positioning assistance data.

[0323] Rule 7b: Terminal measurement of the first PRS;

[0324] Rule 8b: Terminal measurement of the second PRS.

[0325] For example, regarding rule 3b above, the terminal's priority in measuring the first PRS can be considered as the protocol constraining the first PRS to have a higher priority than the second PRS.

[0326] For example, regarding rule 6b above, if the PRS is R16 PRS,

[0327] Case 1: Stop the original R16 PRS measurement and restart the measurement based on the positioning assistance data;

[0328] Case 2: Continue the original R16 PRS measurement and then measure based on the positioning auxiliary data.

[0329] For example, regarding rule 6b above, if the PRS is on demand PRS,

[0330] Case 1: Stop the original on-demand PRS measurement and restart the measurement based on the positioning assistance data;

[0331] Case 2: Continue the original on-demand PRS measurement and then measure based on the positioning auxiliary data.

[0332] Further, optionally, in the embodiments of this application, the terminal prioritizes measuring the first PRS, including any of the following:

[0333] Terminals that support the first PRS only measure the first PRS;

[0334] The terminal prioritizes measuring the first PRS based on its measurement capabilities, and continues to measure the second PRS while the terminal still has measurement capabilities.

[0335] Further, optionally, in embodiments of this application, the conflict between the first PRS and the second PRS includes at least one of the following:

[0336] The first PRS and the second PRS overlap in time, but they are in different frequency bands.

[0337] The first PRS and the second PRS overlap in time, but the first PRS and the second PRS are on different carriers or BWPs.

[0338] The first PRS and the second PRS overlap in time, but they are in the same frequency band and have different RE resource blocks.

[0339] The first PRS and the second PRS overlap in time and RE.

[0340] For example, the aforementioned conflict between the first PRS and the second PRS can be considered as a conflict between at least a portion of the first PRS and the second PRS. For instance, in the case where at least one symbol in the first PRS conflicts with the second PRS,

[0341] For example, a terminal that supports the first PRS only measures the first PRS. This can be understood as, after configuring the first PRS, only the first PRS is measured. If the first PRS is not configured, the second PRS is measured.

[0342] Example 1: On-demand PRS and R16 PRS overlap in time and operate on different frequency bands;

[0343] Example 2: On-demand PRS and R16 PRS overlap in time, share the same frequency band, but have different REs;

[0344] Example 3: On-demand PRS and R16 PRS overlap in time and RE.

[0345] Further, optionally, in embodiments of this application, the conflict between the first PRS and the second PRS includes at least one of the following:

[0346] The switching interval of the first PRS overlaps with that of the second PRS in time;

[0347] The activation time of the first PRS overlaps with that of the second PRS in time;

[0348] The measurement gap (MG) switching time of the first PRS overlaps with that of the second PRS in time.

[0349] For example, the handover interval of the first PRS mentioned above includes at least one of the following: the time interval for updating the configuration of the first PRS, and the time interval for switching carriers or BWPs of the first PRS.

[0350] In one example, the time interval for updating the configuration of the first PRS can be considered as follows: it is expected that the new PRS reception will occur at T0, and the first positioning assistance data will be received at T0-Toffset to update the configuration of the first PRS; or, the first positioning assistance data will be received at T0 to update the configuration of the first PRS, and the configuration of the first PRS will be completed at T0+Toffset.

[0351] In one example, the time interval for the first PRS to switch carriers or BWPs can be considered as follows: it is expected that a new PRS reception will occur at T1, and the first positioning assistance data is received at T1-Toffset to switch the carriers or BWPs of the first PRS; or, the first positioning assistance data is received at T1 to switch the carriers or BWPs of the first PRS, and the switching of the carriers or BWPs of the first PRS is completed at T1+Toffset.

[0352] For example, the activation time of the first PRS may include at least one of the following: the time interval between the activation command and the transmission of the PRS, the time information for activating the first PRS included in the target information, and / or the time information for deactivating the first PRS.

[0353] For example, the MG switching time of the first PRS is used to indicate the time interval between the activation of the BWP and the MG.

[0354] Optionally, in the embodiments of this application, the PRS measurement method provided in the embodiments of this application may further include the following steps:

[0355] Step B1: Upon receiving the first positioning assistance data, release the previously saved first positioning assistance data.

[0356] Alternatively, in step B2: upon receiving the first positioning assistance data and configuring the first PRS, release the previously saved first and second positioning assistance data.

[0357] Alternatively, in step B3: upon receiving the first positioning assistance data and configuring the second PRS, release the previously saved first and second positioning assistance data.

[0358] In the PRS measurement method provided in this application embodiment, after receiving the first PRS and / or the second PRS, the terminal can measure the target PRS (the first PRS and / or the second PRS) and / or report first information related to the target PRS (at least one of the terminal's location information and the target PRS measurement information) based on the target information. Thus, the terminal determines the target PRS that needs to be measured based on the target information, enabling the terminal to clearly understand its own measurement behavior, achieving terminal positioning, and improving the system's communication efficiency.

[0359] The following examples will exemplify the technical solutions provided in the embodiments of this application.

[0360] Example 1:

[0361] Regarding the process by which the terminal measures the target PRS based on the second information:

[0362] Step 1: The terminal receives at least one location assistance data, wherein the at least one location assistance data is...

[0363] Step 2 (optional): The terminal receives a location request message, which is used to request the measurement of the first PRS.

[0364] Step 3: The terminal measures the first PRS based on the positioning assistance data and / or location request message.

[0365] For example, the terminal measuring the first PRS based on positioning assistance data includes at least one of the following:

[0366] If the first positioning assistance data includes the deactivation information of the first PRS, stop the measurement of the PRS;

[0367] If the first positioning assistance data is updated or reconfigured, stop the PRS measurement;

[0368] If the first positioning assistance data is configured or activated, measure the PRS contained in the first positioning assistance data;

[0369] If the first positioning assistance data is updated or reconfigured, restart the PRS measurement.

[0370] Example 2:

[0371] Regarding the process by which the terminal measures the target PRS based on the second information:

[0372] Step 1: The terminal receives the second positioning assistance data, which does not include the first PRS, but only the second PRS.

[0373] Step 2: The terminal receives a location request message, which is used to request the measurement of the target PRS.

[0374] The location request message is the same for both the first PRS and the second PRS, and is sent only once in a location scenario.

[0375] Step 3: The terminal receives the first positioning assistance data.

[0376] In one example, the first positioning assistance data includes the priority of the first PRS.

[0377] Furthermore, if the priority is 1 or greater than x, only the first PRS is measured; and / or, if the priority is 0 or less than or equal to x, the target PRS is determined by combining the priority of the second PRS and the priority of the first PRS; and / or, if the first positioning assistance data includes deactivation information of the first PRS, only the second PRS is measured; and / or, once the first positioning assistance data is received, the previously saved positioning assistance data is released.

[0378] Step 4: The terminal measures the first PRS based on the first positioning assistance data.

[0379] In one example, the terminal measures the first PRS based on the first positioning assistance data, including at least one of the following: the terminal determines the target PRS based on the PRS included in the first positioning assistance data or the PRS included in the stored positioning assistance data; the terminal determines the target PRS based on the priority of the first PRS.

[0380] Example 3:

[0381] Regarding the process by which the terminal measures the target PRS based on the second information:

[0382] Step 1: The terminal receives the first positioning assistance data and / or the second positioning assistance data.

[0383] The first positioning auxiliary data includes the first PRS.

[0384] The second positioning auxiliary data does not include the first PRS, but only the second PRS.

[0385] Step 2: The terminal receives the location request message 1.

[0386] In this example, the location request message 1 is used to request the measurement of the target PRS. Specifically, this can be understood as follows: the location request message in this example needs to be resent every time the positioning assistance data is updated; or, the type of positioning assistance data updated applies to the first PRS and the second PRS respectively.

[0387] Step 3: The terminal receives the new first positioning assistance data.

[0388] Step 4: The terminal receives location request message 2.

[0389] Among them, the location request message 2 is used to request the measurement of the first PRS.

[0390] In one example, the location request message 2 contains a first PRS measurement indication identifier or a first PRS measurement priority information.

[0391] Step 5: The terminal measures the first PRS based on the positioning assistance data and / or location request message.

[0392] In one example, the terminal can determine the target PRS based on the first PRS measurement indication identifier or the first measurement priority information in the location request message.

[0393] In one example, the terminal can determine the target PRS based on the first PRS measurement indication identifier in the location request message, or the first measurement priority information and positioning assistance data.

[0394] Example 4:

[0395] The process by which the terminal measures the target PRS according to predetermined rules and second information:

[0396] Step 1: The terminal receives the second information.

[0397] The second information includes the first positioning assistance data.

[0398] Step 2: The terminal confirms the target PRS based on predetermined rules and priority information.

[0399] In one example, the first positioning assistance data includes priority information for the first PRS.

[0400] Furthermore, the aforementioned predetermined rules may include at least one of the following: if the priority is 1 or greater than x, then only the first PRS is measured; and / or, if the priority is 0 or less than or equal to x, then the target reference signal is determined by combining the priority of the second PRS and the priority of the first PRS; and / or, the target PRS to be measured is determined based on the priority of TRP and FL (frequency layer) in the predetermined rules; and / or, if the first positioning assistance data includes deactivation information of the first PRS, then only the second PRS is measured.

[0401] In one example, the first positioning assistance data includes indication information. Thus, once the first positioning assistance data is received, the previously saved positioning assistance data is released.

[0402] In one example, if the priority of the first PRS is greater than X or greater than the priority of the second PRS, then the first PRS is measured.

[0403] In one example, if there is a first PRS measurement indication flag or priority information of 1, then the first PRS is measured.

[0404] In one example, the target PRS is determined by sorting all the second PRSs according to their priority.

[0405] Step 3: The terminal measures the target PRS based on the positioning assistance data and / or location request message.

[0406] In one example, the terminal determines the target PRS based on the first PRS measurement indication identifier or the first PRS measurement priority information in the location request message.

[0407] In one example, the terminal determines the target PRS based on the first PRS measurement indication identifier in the location request message, or the first PRS measurement priority information and positioning assistance data.
