[0055] The positioning method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0056] Please see Figure 2 , Figure 2 This is a flowchart of a positioning method provided in an embodiment of this application. The positioning method includes:

[0057] Step 201: The first network device acquires the first target information.

[0058] Step 202: The first network device initiates a location process based on the first target information;

[0059] The positioning process includes at least one of the following:

[0060] Send target indication information to a second network device and / or terminal, wherein the target indication information is used to indicate the positioning reference signal (PRS) measurement method of the terminal;

[0061] Send at least one of Measurement Gap (MG) configuration and MG activation information to the second network device and / or terminal;

[0062] Send PRS processing window configuration to the second network device and / or terminal.

[0063] In the above, the first network device can be a (serving) base station, and the second network device can be a location server. The first network device can determine whether the terminal's non-serving cell meets the terminal's PRS measurement conditions based on the first target information, and initiate a positioning process based on the determination result. The PRS measurement conditions include, but are not limited to: the reception timing difference between the terminal's non-serving cell and the terminal's serving cell is less than or equal to a target timing difference threshold. The target timing difference threshold can be obtained by at least one method, such as protocol agreement, indication from other nodes, or terminal capability reporting. The PRS measurement conditions can also be expressed as PRS synchronization conditions. The terminal's non-serving cell can also be understood as the terminal's neighboring cells.

[0064] Optionally, the timing difference between the non-serving cell and the serving cell of the terminal is less than or equal to the target timing difference threshold, which can be understood as:

[0065] The timing difference between the timing of the non-serving cell of the terminal and the timing of the serving cell of the terminal is less than or equal to a target timing difference threshold; or, the reception timing difference between the reception timing of the non-serving cell of the terminal and the reception timing of the serving cell of the terminal is less than or equal to a target timing difference threshold; or, the reception timing difference between the PRS of the non-serving cell of the terminal and the PRS of the serving cell of the terminal is less than or equal to a target timing difference threshold.

[0066] In this embodiment, a first network device acquires first target information; the first network device initiates a positioning process based on the first target information; wherein the positioning process includes at least one of the following: sending target indication information to a second network device and / or a terminal, wherein the target indication information is used to indicate the PRS measurement mode of the terminal; sending at least one of MG configuration and MG activation information to the second network device and / or the terminal; and sending PRS processing window configuration to the second network device and / or the terminal. The first network device initiating the positioning process in the above manner facilitates terminal positioning and improves positioning performance.

[0067] In this application, measuring PRS using the active portion bandwidth (BWP) can be understood as "measuring PRS using a PRS processing window", or "measuring PRS in the absence of a measurement interval", or "measuring PRS outside of a measurement interval".

[0068] In the above, the first target information includes at least one of the following:

[0069] Information about the non-serving cell of the terminal;

[0070] The terminal's capability information;

[0071] Time difference threshold information;

[0072] The instruction information sent by the second network device.

[0073] The non-serving cells of the terminal include all or part of the non-serving cells corresponding to the PRS measured by the terminal. Information about the non-serving cells and / or the terminal's capability information is obtained from the terminal itself, or from the second network device.

[0074] The information of the non-serving cell of the terminal includes at least one of the following:

[0075] The time information of the non-serving cell of the terminal;

[0076] Frequency domain information of the non-serving cell of the terminal;

[0077] The terminal's non-serving cell identification information.

[0078] The time information of non-serving cells includes at least one of the following:

[0079] The expected reference signal time difference and uncertainty between the non-serving cell and the reference cell or the first network device (e.g., a base station), or the PRS search window (expected RSTD+-uncertain), the offset between the non-serving cell and the reference cell or the first network device's system frame number 0 (SFN0), such as SFN0-offset, the SFN initialization time of the non-serving cell, and synchronization information between non-serving cells (or between the non-serving cell and the reference cell, or between the non-serving cell and the serving cell) (such as relative time difference (RTD) information, used for time synchronization between two cells). Here, the timing of the serving cell is the timing of the primary cell.

[0080] The frequency domain information of a non-serving cell includes at least one of the following: the location frequency layer identifier, frequency point, point-A, bandwidth, subcarrier spacing, starting frequency domain location, etc., corresponding to the non-serving cell.

[0081] The identification information of a non-serving cell includes at least one of the following: location frequency layer identifier, TRP identifier, PRS resource set identifier, PRS identifier, physical cell identifier (PCI), new radio interface cell global identifier (NCGI), and absolute radio frequency channel number (ARFCN).

[0082] In the above description, the indication information is used to indicate whether to determine whether the non-serving cell of the terminal meets the PRS measurement conditions. That is, the indication information indicates whether the first network device should determine whether the non-serving cell meets the PRS measurement conditions. For example, if the second network device (e.g., a location server) obtains that the UE supports sliding correlation, then it is not necessary to determine whether the non-serving cell meets the PRS measurement conditions. Optionally, it can also be implicitly indicated; for example, if the indication information sent by the second network device does not include at least one of the terminal's non-serving cell information, UE capabilities, and timing difference threshold information, then the first network device does not need to determine whether the non-serving cell meets the PRS measurement conditions.

[0083] In one embodiment of this application, the positioning process further includes one of the following:

[0084] Configure the terminal with an MG for measuring the PRS of the first target;

[0085] Delete the PRS configuration to be measured in the processing window;

[0086] The terminal is instructed to ignore the measurement of the PRS to be measured;

[0087] Send information indicating the PRS to be measured to the second network device.

[0088] The configuration of a MG for measuring a first target PRS for the terminal includes: a first network device configuring an MG for measuring the first target PRS for the terminal based on the relationship between the first target PRS and second target information, and the first target information. The second target information includes at least one of the SCS of a partial bandwidth bandwidth (BWP) and a bandwidth relationship. In other words, the MG configuration is determined by the first network device based on the relationship between the first target PRS to be measured by the terminal and the second target information, and the first target information. The MG configuration includes configuration information for the terminal to use the MG to measure the PRS of the first target PRS. The first target PRS includes the PRS of non-serving cells in the terminal's non-serving cells that meet the PRS measurement conditions.

[0089] If the first network device determines that the non-serving cell of the terminal does not meet the PRS measurement conditions, then the first network device (forcefully) configures MG for a specific PRS (i.e., the PRS of the non-serving cell that does not meet the PRS measurement conditions) (or for some PRS, the first network device still configures MG), or deletes the configuration of the specific PRS in the corresponding processing window, or instructs the UE to ignore the measurement of the specific PRS, or indicates the PRS that does not meet the conditions to the second network device (location server). Optionally, (under a certain positioning frequency layer), if the number of non-serving cells (or TRPs) that do not meet the measurement conditions exceeds N, a relevant indication is sent, such as sending target indication information; or (under a certain positioning frequency layer), if the number of non-serving cells (or TRPs) that meet the measurement conditions does not exceed M, a relevant indication is sent, such as sending target indication information. N and M can be obtained by at least one method: network indication, protocol agreement, or UE indication.

[0090] In one embodiment of this application, after obtaining first target information, the first network device can determine whether the non-serving cells of the terminal meet the PRS measurement conditions based on the first target information, and send target indication information to the second network device. The target indication information is used to indicate a second target PRS, which includes the PRS of the non-serving cells of the terminal that do not meet the PRS measurement conditions. The second network device can further send the target indication information to the UE.

[0091] Optionally, the second target PRS includes at least one of the following: the PRS of at least one non-serving cell, the PRS of at least one TRP, and the PRS of at least one positioning frequency layer. The second target PRS includes at least one of the following: positioning frequency layer identifier, TRP identifier, PRS resource set identifier, PRS identifier, identifier of the cell transmitting the PRS, cell or TRP number, etc. The target indication information indicates that the PRS corresponding to these identifiers does not meet the measurement threshold, or indicates that the UE can ignore the PRS corresponding to these identifiers.

[0092] In one embodiment of this application, the target indication information is used to instruct the terminal to ignore the measurement of a third target PRS and / or to measure a fourth target PRS when using an activated BWP for PRS measurement. That is, the target indication information is used to instruct the UE to ignore the measurement of the third target PRS when measuring PRS with the BWP, and / or to instruct the UE to measure the PRS (i.e., the fourth target PRS) when measuring PRS with the BWP. The target indication information may be included in the PRS processing window configuration indication. Optionally, the PRS processing window configuration indication is unrelated to the third target PRS; for example, the PRS processing window configuration indication instructs the UE to ignore the measurement of the third target PRS (explicit indication); or the PRS processing window configuration indication does not include the configuration of the third target PRS (implicit indication). That is, the PRS processing window configuration is unrelated to the third target PRS. Optionally, the PRS processing window configuration instructs the UE to measure the fourth target PRS (explicit indication); or the PRS processing window configuration only includes the fourth target PRS (implicit indication).

[0093] The third target PRS includes the PRS of non-serving cells that do not meet the PRS measurement conditions, and / or the fourth target PRS includes the PRS of non-serving cells that meet the PRS measurement conditions.

[0094] The third target PRS includes at least one of the following:

[0095] At least one non-serving cell's PRS;

[0096] PRS of at least one transmitting and receiving point TRP;

[0097] At least one PRS for the positioning frequency layer;

[0098] And / or,

[0099] The fourth objective PRS includes at least one of the following:

[0100] At least one non-serving cell's PRS;

[0101] At least one TRP's PRS;

[0102] At least one PRS for the positioning frequency layer.

[0103] The third target PRS includes at least one of the following:

[0104] The positioning frequency layer identifier corresponding to the third target PRS;

[0105] The TRP identifier corresponding to the third target PRS;

[0106] The identifier of the PRS resource set corresponding to the third target PRS;

[0107] The third target PRS identifier;

[0108] The identifier of the cell that sent the third target PRS;

[0109] And / or,

[0110] The fourth objective PRS includes at least one of the following:

[0111] The positioning frequency layer identifier corresponding to the fourth target PRS;

[0112] The TRP identifier corresponding to the fourth target PRS;

[0113] The identifier of the PRS resource set corresponding to the fourth target PRS;

[0114] The fourth target PRS identifier;

[0115] The identifier of the cell that sends the fourth target PRS.

[0116] The fourth target PRS is the PRS in the PRS configuration information, which is related to the terminal using an active BWP for measurement. Optionally, the PRS configuration information differs from the PRS configuration corresponding to the UE using MG; the PRS configuration information is only used for measurements via BWP. Optionally, the PRS configuration is related to the PRS processing window, or the PRS configuration is the PRS configuration when the UE uses an active BWP or PRS processing window to measure PRS. For example, the fourth target PRS configuration carries an identifier to indicate that this PRS configuration is specifically used for BWP PRS measurement.

[0117] In one embodiment of this application, the PRS processing window configuration does not include the configuration of the fifth target PRS, or the PRS processing window configuration is unrelated to the fifth target PRS.

[0118] Optionally, the fifth target PRS includes at least one of the following:

[0119] At least one non-serving cell's PRS;

[0120] At least one TRP's PRS;

[0121] At least one PRS for the positioning frequency layer;

[0122] PRS of non-serving cells that do not meet the PRS measurement conditions.

[0123] In one embodiment of this application, the target indication information is used to indicate at least one of the following: whether the terminal can request a Media Access Control (MG), whether the terminal can request a Public Relations System (PRS) window, whether the second network device has already requested an MG, whether the second network device has already requested a PRS window, the method by which the terminal requests an MG, and the method by which the terminal requests a PRS window. The method of requesting an MG or a method of requesting a PRS window can be, for example, through a Media Access Control (MAC) control element (CE) request, a Radio Resource Control (RRC) request, or an Uplink control information (UCI) request.

[0124] Optionally, whether the second network device has requested the MG and / or PRS processing window is determined by the second network device requesting the MG and / or PRS processing window from the first network device via NR positioning protocol A (NRPPa).

[0125] Optionally, whether the terminal can request the MG and / or PRS processing window refers to whether the first network device or the second network device allows the terminal to request the MG and / or PRS processing window from the first network device via signaling.

[0126] Optionally, if the terminal receives a target indication message, a location information request, or one of the latter messages, it starts a timer to receive MG configuration (or activation) or PRS processing window configuration (or activation) messages within the timer. After the timer ends (or is released, or stopped), if the terminal does not receive the MG configuration (or activation) or PRS processing window configuration (or activation) message, the UE initiates a request for MG or PRS processing window configuration (or activation) to the first network device (or the second network device) and / or reports information that the MG or PRS processing window configuration has failed.

[0127] Optionally, if the terminal receives a target indication message, a location information request, or one of these messages (or the latter), a timer is started to receive the MG configuration (or activation) message within the timer. After the timer ends (or is released, or stopped), if the terminal does not receive the MG configuration (or activation) message, the UE initiates an MG configuration (or activation) request to the first network device (or the second network device) and / or reports MG configuration failure information. Optionally, the timer is only used when the terminal uses the MG to measure the PRS. If the terminal determines or receives an indication confirming that the target PRS can be measured using the active BWP, then the terminal ignores the timer.

[0128] Optionally, the start time of the timer is the time when the terminal receives a target indication message, a location information request, or a message that comes later than either of the two; the length (or end time) of the timer can be determined by at least one of the following: instruction from the network device (first network device or second network device), protocol agreement, or selection by the terminal.

[0129] In another embodiment of this application, before or after the first network device sends the target indication information, it obtains indication information from the second network device or terminal. This indication information indicates the terminal's location service requirements (e.g., the first network device instructing the second network device), including at least one of a Quality of Service (QoS) requirement and a terminal measurement performance requirement. The QoS requirement includes at least one of a positioning accuracy requirement and a positioning delay requirement. Optionally, the terminal measurement performance requirement information is the measurement performance requirement corresponding to the current terminal measurement quantity (e.g., Reference Signal Time Difference (RSTD), Reference Signal Received Power (RSRP), or Receive-Transmit Time Difference (Rx-Tx time difference), representing the requirements that the measurement quantity reported by the terminal should meet, including at least one of an accuracy measurement performance requirement and a delay measurement performance requirement. For example, it may indicate an accuracy measurement performance requirement, or a requirement table corresponding to accuracy and PRS bandwidth, signal-to-noise ratio, subcarrier spacing, channel type, etc.

[0130] The capability information of the terminal mentioned above includes at least one of the following:

[0131] Does it support processing PRS while the DownLink (DL) BWP is active (or within the PRS processing window)?

[0132] Does it support processing PRS using MG?

[0133] The processing capability of PRS is used to process MG;

[0134] Activate the DL BWP (or process PRS in the PRS processing window) to enable PRS processing capabilities;

[0135] Whether sliding correlation and / or Fast Fourier Transform (FFT) processing of PRS is supported; further, whether sliding correlation and / or FFT processing of PRS is supported under the condition that DL BWP processing of PRS is activated and / or under the condition that MG processing of PRS is supported.

[0136] Whether it supports processing PRS of asynchronous neighboring cells; further, whether it supports processing PRS of asynchronous neighboring cells under the conditions of DL BWP processing PRS and / or MG processing PRS.

[0137] Does it support ignoring the timing difference threshold when processing PRS for non-serving cells? Furthermore, does it support ignoring the timing difference threshold when processing PRS for non-serving cells under the conditions of DL BWP activation and / or MG PRS activation?

[0138] The range of the reception timing difference threshold between the non-serving cell and the serving cell that can be processed is supported. Furthermore, under the conditions of DL BWP processing PRS and / or MG processing PRS, the range of the reception timing difference threshold between the non-serving cell and the serving cell that can be processed is supported. For example, the (maximum +-) threshold of the reception timing difference (Rx time difference) between the non-serving cell and the serving cell can be processed. Optionally, when this value is defaulted, or is 0, or takes a maximum value, the UE can be instructed to ignore the timing difference threshold when processing the non-serving cell PRS.

[0139] Does the system support processing PRS for non-serving cells exceeding a timing difference threshold? Furthermore, does it support processing PRS for non-serving cells exceeding a timing difference threshold when DL BWP is activated and / or MG is used for PRS processing? Optionally, the timing difference threshold is determined by at least one method: network indication, protocol agreement, or terminal selection. For example, the timing difference threshold could be the length of the cyclic prefix (CP).

[0140] Optionally, the terminal capability type can be per UE or per band.

[0141] The UE can report capability information to the first network device and / or the second network device. The terminal's capability information can be reported separately or included in the PRS-related capability measurement using the active BWP (or using the PRS processing window).

[0142] Here, sliding correlation can also be understood as time-domain correlation processing, or time-domain processing. FFT processing can also be understood as Discrete Fourier Transform (DFT) processing, or frequency-domain sampling processing, or frequency-domain processing.

[0143] Optionally, the reception timing difference between the non-serving cell and the serving cell of the terminal can be understood as:

[0144] The timing difference between the timing of the non-serving cell of the terminal and the timing of the serving cell of the terminal; or, the reception timing difference between the reception timing of the non-serving cell of the terminal and the reception timing of the serving cell of the terminal; or, the reception timing difference between the PRS of the non-serving cell of the terminal and the PRS of the serving cell; or, the reception timing difference between the PRS of the non-serving cell of the terminal and the timing of the serving cell.

[0145] When the terminal's capability information is sent to the first network device, it can be either directly sent by the UE to the first network device, or sent by the UE to the second network device, which then sends it to the first network device.

[0146] If the UE is capable of handling sliding correlation PRS, or handling asynchronous neighbor cell PRS, or handling a large Rx time difference between the non-serving cell and the serving cell, it can be assumed that the UE can ignore the PRS measurement conditions to handle the PRS of the non-serving cell.

[0147] Optionally, the target indication information is used to instruct the terminal to perform PRS measurement using an activated BWP under at least one of the following assumptions:

[0148] All non-serving cells to be measured meet the PRS measurement conditions;

[0149] All non-serving cells to be measured are synchronized with the serving cells;

[0150] When the terminal supports a sliding window, it ignores whether all non-serving cells to be measured meet the PRS measurement conditions, or it ignores whether all non-serving cells to be measured are synchronized with the serving cell.

[0151] In other words, under the scheme where the first network device determines whether the terminal's non-serving cell meets the terminal's PRS measurement conditions based on the target information, when the terminal measures PRS under active BWP, the UE makes at least one of the following assumptions:

[0152] When the UE uses the active DL BWP to measure the PRS, the UE assumes that all neighboring cell TRPs to be measured meet the condition threshold.

[0153] When a UE uses an active DL BWP to measure PRS, the UE assumes that the TRP of all neighboring cells to be measured is synchronized with the serving cell.

[0154] If the UE can support a sliding window, when the UE uses active DL BWP to measure PRS, the UE ignores whether the TRP of all neighboring cells to be measured meets the condition threshold, or ignores whether the TRP of all neighboring cells to be measured is synchronized with the serving cell.

[0155] Alternatively, when the terminal measures PRS under active BWP, the UE makes at least one of the following assumptions:

[0156] When the UE uses the active DL BWP to measure the PRS, the UE assumes that all neighboring cell TRPs to be measured meet the condition threshold.

[0158] If the UE can support a sliding window, when the UE uses active DL BWP to measure PRS, the UE ignores whether the TRP of all neighboring cells to be measured meets the condition threshold, or ignores whether the TRP of all neighboring cells to be measured is synchronized with the serving cell.

[0159] Please see Figure 3 , Figure 3 This is a flowchart of a positioning method provided in an embodiment of this application, such as... Figure 3 As shown, the positioning method provided in this application includes:

[0160] Step 301: The terminal acquires target information;

[0161] Step 302: The terminal initiates a location process based on the target information;

[0162] The positioning process includes at least one of the following:

[0163] Send target indication information to the first network device, wherein the target indication information is used to indicate the PRS of a non-serving cell that does not meet the PRS measurement conditions;

[0166] Report the measurement results;

[0167] Report location information;

[0168] A Measurement Interval (MG) request is sent to the second network device, the MG request being used to request the use of MG for PRS measurement.

[0169] Specifically, the first network device can be a base station, and the second network device can be a location server. The terminal determines whether its non-serving cell meets the PRS measurement conditions based on the target information; the terminal initiates the positioning process based on whether its non-serving cell meets the PRS measurement conditions. The PRS measurement conditions include, but are not limited to: the reception timing difference between the terminal's non-serving cell and its serving cell is less than or equal to a target timing difference threshold. The target timing difference threshold can be obtained through at least one method, such as protocol agreement, indication from other nodes, or terminal capability reporting. The PRS measurement conditions can also be expressed as PRS synchronization conditions. The terminal's non-serving cell can also be understood as the terminal's neighboring cells.

[0170] Optionally, the timing difference between the non-serving cell and the serving cell of the terminal is less than or equal to the target timing difference threshold, which can be understood as:

[0171] The timing difference between the timing of the non-serving cell of the terminal and the timing of the serving cell of the terminal is less than or equal to a target timing difference threshold; or, the reception timing difference between the reception timing of the non-serving cell of the terminal and the reception timing of the serving cell of the terminal is less than or equal to a target timing difference threshold; or, the reception timing difference between the PRS of the non-serving cell of the terminal and the PRS of the serving cell is less than or equal to a target timing difference threshold.

[0172] In this embodiment, the terminal acquires target information; based on the target information, the terminal initiates a positioning process; wherein the positioning process includes at least one of the following: sending target indication information to a first network device, wherein the target indication information is used to indicate the PRS of a non-serving cell that does not meet the PRS measurement conditions; measuring the PRS; ignoring the measurement of PRS that does not meet the measurement conditions, provided that the terminal uses BWP to measure the PRS; reporting the measurement results; reporting location information; and sending a Measurement Interval (MG) request to a second network device, wherein the MG request is used to request the use of MG for PRS measurement. By having the terminal initiate the positioning process in the above manner, positioning can be facilitated and positioning performance can be improved.

[0173] In this application, measuring PRS using the active bandwidth part (BWP) can be understood as "measuring PRS using a PRS processing window", or "measuring PRS in the absence of a measurement gap (MG)", or "measuring PRS outside of a measurement gap (MG)".

[0174] The target information mentioned above includes at least one of the following:

[0175] Information about the non-serving cell (or TRP) of the terminal;

[0176] Time difference threshold information.

[0184] The frequency domain information of a non-serving cell includes at least one of the following: the location frequency layer identifier, frequency point, point-A, bandwidth, subcarrier spacing, starting frequency domain location, etc., corresponding to the non-serving cell.

[0186] The information about the non-serving cell of the terminal is obtained from the first network device or from the second network device.

[0187] In one embodiment of this application, after the UE obtains the target information, if the UE wishes to use MG to measure the PRS of the first target, the UE sends an MG request to the first network device. The MG request is used to request the use of MG to measure the PRS of the first target.

N and M can be obtained through at least one method: network indication, protocol agreement, or UE indication.

[0197] The first PRS SCS does not match the active BWP;

[0198] The accuracy requirement of the first PRS does not match the bandwidth within the active BWP.

[0199] In one embodiment of this application, after obtaining the target information, the UE does not expect to perform measurement and report the corresponding measurement results for PRS that do not meet the PRS measurement conditions. In this case, the UE can ignore the measurement of PRS that do not meet the measurement conditions, provided that the BWP is activated to measure the PRS.

[0200] In one embodiment of this application, after obtaining target information, the UE can send target indication information to a second network device (i.e., a location server) to indicate that the second target PRS does not meet the measurement conditions for a PRS that does not meet the measurement conditions. The second target PRS includes the PRS of at least one non-serving cell and / or the PRS of at least one TRP;
