Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a positioning processing method, a terminal, and a network-side device. Background Art

[0002] For positioning methods based on time measurement (e.g., a positioning method based on Round Trip Time (RTT-based), a positioning method based on Time Difference of Arrival (TDOA-based)), when calculating the position of a User Equipment (UE), the positioning accuracy will be affected by the Transmission Reference Point (TRP) and the Rx / Tx timing error of the UE.

[0003] Taking the RTT-based positioning method as an example, the influence of Rx / Tx timing error on positioning is as Figure 1 shown.

[0004] The measured value of the time difference Rx - Tx between the reception and transmission of the UE and the TRP can be written as:

[0005] (Rx - Tx) UE = t1 - t2

[0006] (Rx - Tx) TRP = t3 - t0

[0007] Wherein, t1 is the time when the UE receives the Downlink Positioning Reference Signal (DL PRS) from the TRP, t2 is the transmission time of the Sounding Reference Signal (SRS), t3 is the time when the SRS is received from the TRP, and t0 is the transmission time of the DL PRS.

[0008] The RTT value between the UE and the TRP can be calculated as:

[0009] RTT meas =(Rx - Tx) TRP +(Rx - Tx) UE = t3 - t0 + t1 - t2 = t1 - t0 + t3 - t2

[0010] However, all the above sending and receiving times are obtained in the baseband, and they consist of the actual propagation delay and Rx / Tx timing error, as shown in the following formula:

[0011] RTT meas = 2 * T prop + (e0 + e3) + (e1 + e2)

[0012] = 2 * T prop + e TRP + e UE

[0013] Where T prop is the actual propagation delay between the UE and the TRP, e0 is the transmission time error (Tx timing error) of the TRP, e3 is the reception time error (Rx timing error) of the TRP, e1 is the Rx timing error of the UE, e2 is the Tx timing error of the UE, and e TRP is the total timing error (timing error) of the TRP side including e0 and e3, and e UE is the timing error of the UE side including e1 and e2.

[0014] Due to the influence of Rx / Tx timing, the positioning based on RTT will be affected. Similarly, other time-based positioning methods will also be affected.

[0015] Therefore, how to eliminate the Rx / Tx timing error and improve the positioning accuracy has become an urgent problem to be solved in the current positioning technology. Summary of the Invention

[0066] Tx time error: From the perspective of signal transmission, there will be a time delay from the time when the digital signal is generated in the baseband to the time when the RF signal is transmitted from the Tx antenna. To support positioning, the UE / TRP can perform internal calibration / compensation of the Tx time delay (Tx time dela9) for the transmission of DL PRS / UL SRS signals. The remaining Tx time delay after calibration or the uncalibrated Tx time delay is defined as the Tx time error. From the above figure, the Tx timing error on the UE side can be understood as the time from the BB to the Ant in the light blue part.

[0067] Rx Time Error: From the perspective of signal reception, there is a time delay from receiving the RF signal at the Rx antenna to baseband processing. To support positioning, the UE / TRP can perform internal calibration / compensation of the Rx time delay (Rx time delay) on the measurement results of DL PRS / UL SRS before measurement reporting. The remaining Rx time delay after calibration or the uncalibrated Rx time delay is defined as the Rx time error. From the figure above, the Rx timing error on the UE side can be understood as the time from Ant to BB in the light blue part.

[0068] UE Tx Timing Error Group (UE Tx ‘timing error group’ (UE Tx TEG)): The UE Tx TEG is associated with the transmission of one or more UL SRS resources used for positioning, and the Tx time errors of these resources are within a certain range. From the discussion, it is considered that the SRS transmitted by the same Tx panel can be associated with the same UE Tx TEG.

[0069] TRP Tx Timing Error Group (TRP Tx ‘timing error group’ (TRP Tx TEG)): The TRP Tx TEG is associated with the transmission of one or more DL PRS resources, and the Tx time errors of these resources are within a certain range. From the discussion, it can be considered that the PRS transmitted by the same Tx panel can be associated with the same TRP Tx TEG.

[0070] UE Rx Timing Error Group (UE Rx ‘timing error group’ (UE Rx TEG)): The UE Rx TEG is associated with one or more DL measurements, and the Rx time errors of these measurements are within a certain range.

From the discussion, it can be considered that the SRS measurement results measured by the same Rx panel can be associated with the same TRP Tx TEG.

[0072] UE RxTx 'timing error group' (UE RxTx TEG): The UE RxTx TEG is associated with one or more UE Rx-Tx time difference measurements and one or more UL SRS resources, and the "Rx timing error + Tx timing error" of these resources is within a certain range.

[0073] TRP RxTx 'timing error group' (TRP RxTx TEG): The TRP RxTx TEG is associated with one or more gNB Rx-Tx time difference measurements and one or more DL PRS resources, and the "Rx timing error + Tx timing error" of these resources is within a certain range.

[0074] The following will combine the accompanying drawings and, through some embodiments and their application scenarios, elaborate on the positioning processing method provided by the embodiments of the present application in detail.

[0075] As Figure 3 shown, the positioning processing method of the embodiments of the present application includes:

[0076] Step 301, the terminal sends first indication information;

[0077] Among them, the first indication information is used to indicate at least one of the following:

[0078] The association relationship between the uplink positioning reference signal and the time error group TEG;

[0079] The association relationship between the positioning measurement result and the TEG.

[0080] Among them, the uplink positioning reference signal includes but is not limited to at least one of the following: SRS for positioning, SRS for MIMO, PRACH, etc. The positioning measurement result includes but is not limited to at least one of the following: DL RSTD, UE Rx-Tx time difference measurement result, measurement result related to DL-AOD.

[0081] In this way, by sending the first indication information to the first network-side device, the first network-side device can learn the association relationship between the uplink positioning reference signal and the TEG, and / or the association relationship between the positioning measurement result and the TEG, and eliminate the Rx / Tx timing error based on this association relationship during positioning, achieving the purpose of improving the positioning accuracy. Here, the first network-side device may be a location server.

[0082] For example, in downlink positioning, the same UE will receive positioning reference signals (PRS) from multiple TRPs and obtain multiple downlink (DL) measurement results. If multiple DL measurement results can be associated with the same UE Rx timing error group (TEG), then the difference can be calculated when processing multiple DL measurement results to eliminate the same UE Rx timing error. When the UE reports the DL measurement results to the first network device (such as a location server (LMF)), it can indicate the association between the DL measurement results and the UE Rx TEG to assist the first network device in completing further positioning calculations.

[0083] Similarly, in uplink positioning, when the UE sends a sounding reference signal (SRS), it can indicate the association between the SRS and the Tx TEG. In downlink + uplink positioning (such as RTT positioning), the UE will report the measurement result of the Rx - Tx time difference and can provide the association between the measurement result and the Tx TEG and / or Rx TEG, or the association with the RxTx TEG.

[0084] In addition to the UE, on the TRP side, the TRP can also indicate the association between the TRP - side TEG (Rx TEG and / or Tx TEG) and the measurement result, and / or the association between the TEG (Rx TEG and / or Tx TEG) and the reference signal.

[0085] In this embodiment, the TEG can be Tx TEG, Rx TEG, RxTx TEG, or {Rx TEG, Tx TEG}. The association can be represented by the associated TEG ID, or the SRS or positioning measurement results of the same TEG are grouped into one group, or in other ways.

[0086] Specifically, the association between the uplink positioning reference signal and the TEG includes at least one of the following:

[0087] The association between the uplink positioning reference signal and the UE Tx TEG;

[0088] The association between the uplink positioning reference signal and the UE RxTx TEG;

[0089] The association between the uplink positioning reference signal and the UE {Rx TEG, Tx TEG};

[0090] Specifically, the association relationship between the positioning measurement result and the TEG includes at least one of the following:

[0091] The association relationship between the positioning measurement result and the UE Rx TEG;

[0092] The association relationship between the positioning measurement result and the UE RxTx TEG;

[0093] The association relationship between the positioning measurement result and the UE{Rx TEG,Tx TEG}.

[0094] Optionally, the method further includes:

[0095] The terminal obtains second indication information, which is used to indicate the signaling method for sending the first indication information, and the signaling method includes one of the following:

[0096] The terminal sends the first indication information to a first network-side device;

[0097] The terminal sends the first indication information to a second network-side device, and then the second network-side device sends it to the first network-side device.

[0098] Optionally, the above 'The terminal sends the first indication information to a second network-side device, and then the second network-side device sends it to the first network-side device' can also be expressed as 'The terminal sends the first indication information to a second network-side device'. Because for the terminal, it only needs to care about which network-side device the first indication information is sent to, rather than the behavior of the network-side device after the information is sent.

[0099] In this way, the terminal sends the first indication information to the first network-side device in the manner indicated by the second indication information. Specifically, the terminal can directly send the first indication information to the first network-side device; it can also send the first indication information to the second network-side device, and the second network-side device sends it to the first network-side device. Among them, the first network-side device is a location server, such as an LMF, and the second network-side device is a base station, including at least one of a serving gNB and a neighboring gNB. Optionally, when the terminal directly sends the first indication information to the first network-side device, it can be sent through an LPP message; when the terminal sends the first indication information to the second network-side device, it can include but is not limited to being sent through at least one of RRC, MAC CE, and UCI. Optionally, which message the terminal uses to send the first indication to the first network-side device or the second network-side device can be determined by at least one of network indication, protocol agreement, UE selection, etc.

[0100] Wherein, when the first indication information is used to indicate at least one of the association relationship between the uplink positioning reference signal and the time error group (TEG) and the association relationship between the positioning measurement result and the TEG, the terminal receives the second indication information.

[0101] The second indication information may be sent by the first network-side device or the second network-side device.

[0102] In addition, optionally, before the terminal sends the first indication information, it further includes:

[0103] The terminal obtains the TEG level information;

[0104] The terminal determines the first indication information according to the TEG level information.

[0105] In this way, after obtaining the TEG level information, the terminal determines the valid first indication information according to the TEG level information.

[0106] Here, the TEG level information can also be referred to as the TEG calibration level, and the acquisition method may include at least one of the following: determined by the terminal independently, agreed by protocol, or (pre)-configured by the network.

[0107] Optionally, the TEG level information includes at least one set of mapping relationships, and each set of mapping relationships includes at least one of the following:

[0108] TEG level identifier;

[0109] Time error threshold corresponding to the TEG level;

[0110] Time error difference threshold corresponding to the TEG level;

[0111] Positioning accuracy requirement corresponding to the TEG level;

[0112] Positioning reference signal configuration information corresponding to the TEG level.

[0113] Among them, the TEG level identifier represents the level of the TEG, such as: L1.

[0114] Among them, the timing error threshold can be the range of the timing error, the boundary of the timing error, or the maximum value and / or minimum value of the timing error. Of course, the timing error threshold can also be the statistical characteristic threshold of the timing error, including but not limited to at least one of the mean, variance, and covariance. Similar to the timing error threshold, the timing error difference threshold can be the range of the timing error difference, the boundary of the timing error difference, or the maximum value and / or minimum value of the timing error difference. Similarly, it can also be the statistical characteristic threshold of the timing error difference. Therefore, if the timing error / timing error difference of two transmissions is less than (or does not exceed, or meets) the corresponding threshold, it can be considered that the timing errors of the two transmissions belong to one TEG. Taking the timing error difference as an example, in the case where the timing error difference is known (or roughly known), if the timing error difference of two transmissions is less than (or does not exceed) this threshold (i.e., the timing error difference threshold), it can be considered that the timing errors of the two transmissions belong to one TEG. For example, the measurement result with the Rx timing error difference less than this threshold can be within one Rx TEG; the uplink reference signal with the Tx timing error difference less than this threshold can be within one Tx TEG; the measurement result and / or uplink reference signal with the Rx+Tx timing error difference less than this threshold can be within one RxTx TEG.

[0115] Among them, the positioning accuracy requirement includes at least one of the accuracy level and the confidence level. The mapping between the positioning accuracy requirement and the TEG level identifier includes at least one of one-to-one correspondence, one-to-many, or many-to-one.

[0116] Among them, the positioning reference signal configuration information includes but is not limited to at least one of the following: bandwidth, such as PRS bandwidth; repetition, such as PRS repetition; subcarrier spacing.

[0117] In this way, the TEG level information can be implemented as follows: the threshold of the timing error difference at L1 level is [x1] ns; the threshold of the timing error difference at L2 level is [x2] ns. Alternatively, the TEG level information is implemented as follows: for the TEG level of L1, the corresponding positioning accuracy requirement is [y1] m.

[0118] For example, the protocol stipulates or the network (pre-)configures the TEG level information as shown in Table 1 below. Taking the time error difference as an example:

[0119] Table 1

[0120]

[0121] In Table 1, each row represents a set of mapping relationships. When the accuracy requirement is less than [0.2 m], the amplitude of the corresponding Timing error difference margin should be less than [2 ns], corresponding to the TEG level L0;

[0122] When the accuracy requirement is less than [0.5 m], the corresponding Timing error difference margin should be less than [5 ns], corresponding to the TEG level L1.

[0123] In addition, in this embodiment, optionally, the method further includes:

[0124] The terminal sends TEG capability information;

[0125] Wherein, the TEG capability information includes indicating a set of mapping relationships, and each set of mapping relationships includes at least one of the following:

[0126] TEG level identifier;

[0127] Time error threshold corresponding to the TEG level;

[0128] Time error difference threshold corresponding to the TEG level;

[0129] Positioning accuracy requirement corresponding to the TEG level;

[0130] Positioning reference signal configuration information corresponding to the TEG level;

[0131] Statistical characteristic parameters of the time error corresponding to the TEG level;

[0132] Statistical characteristic parameters of the time error difference corresponding to the TEG level;

[0133] Number of TEGs corresponding to the TEG level.

[0134] Here, the TEG level identifier, time error threshold, time error difference threshold, positioning accuracy requirement, and positioning reference signal configuration information are as described above and will not be elaborated here. The number of TEGs corresponding to the TEG level, that is, the number of TEGs that can exist for the same TEG level. The statistical characteristic parameters include but are not limited to one of the following: mean, variance, covariance, statistical distribution type, and so on.

[0135] For example, the TEG capability information is shown in Table 2 below. Taking the time error difference as an example:

[0136] Table 2

[0137]

[0138] In Table 2, one row represents a set of mapping relationships. From the content of Table 2, for level L0, the UE does not support it;

[0139] For level L1, only when the timing error difference of 2 transmissions is less than [20 ns] can it belong to 1 TEG, and the number of TEGs that the UE can recognize is 4;

[0140] For level L2, only when the timing error difference of 2 transmissions is less than [100 ns] can it belong to 1 TEG, and the number of TEGs that the UE can recognize is 2;

[0141] For level L3, only when the timing error difference of 2 transmissions is less than [100 ns] can it belong to 1 TEG, and the number of TEGs that the UE can recognize is 1.

[0142] Among them, if the protocol stipulates or the network (pre)-configures the time error difference threshold corresponding to the TEG level, each set of mapping relationships of the TEG capability information may not include this item. Of course, for level L0, since the UE does not support it, a set of mapping relationships with the TEG level of L0 can be omitted in the UE capabilities (that is, this row can be deleted from Table 2).

[0143] Optionally, when the UE does not support 'obtaining the timing error difference', the UE does not provide the mapping relationship shown in Table 2.

[0144] It should also be noted that this TEG capability information can be included in the terminal capability information and sent together with other information when the terminal reports its own capability information.

[0145] In this embodiment, optionally, the method further includes:

[0146] The terminal receives request information from a first network - side device, and the request information is used to request the terminal to provide the first indication information or TEG capability information.

[0147] That is to say, the terminal sends the first indication information or TEG capability information based on the request of the first network - side device. Here, the request of the first network - side device can be a direct request from the first network - side device or an indirect request from the first network - side device. Among them, a direct request means that the first network - side device directly sends request information; an indirect request means that the first network - side device sends a request message to a second network - side device, and then the second network - side device sends it to the terminal. It should be understood that an indirect request can also be equivalent to a request from the second network - side device.

[0148] Optionally, the request information includes at least one of the following:

[0149] Request identifier;

[0150] TEG level identifier;

[0151] Target time error threshold;

[0152] Target time error difference threshold;

[0153] Positioning accuracy requirement;

[0154] TEG capability information request.

[0155] Here, the request identifier is used to indicate the purpose of the request information, such as requesting the terminal to provide the first indication information, or requesting the terminal to provide the TEG capability information, and the request identifier can also be implemented by a request instruction. The TEG level identifier can be used to request the terminal to provide the association relationship between the uplink positioning reference signal and the TEG, and / or the association relationship between the positioning measurement result and the TEG at the corresponding TEG level; or, request the terminal to provide the association relationship between the uplink positioning reference signal and the TEG, and / or the association relationship between the positioning measurement result and the TEG below (or not higher than) or above (or not lower than) the corresponding TEG level. Of course, the TEG level identifier can be used to request the terminal to provide at least one of the time error threshold, time error difference threshold, positioning accuracy requirement, and positioning reference signal configuration information of the corresponding TEG level. The target time error threshold is the time error threshold when the terminal determines the TEG, the target time error difference threshold is the time error difference threshold when the terminal determines the TEG, and the specific implementation of the target time error threshold is the time error threshold as described above, and the specific implementation of the target time error difference threshold is the time error difference threshold as described above, which will not be elaborated here. The positioning accuracy requirement includes at least one of the accuracy level and the confidence level, and is used to request the terminal to provide the corresponding first indication information under this positioning accuracy requirement to assist the terminal in determining the grouping of the TEG. When the request is used to request the TEG capability, the TEG level identifier, the target time error threshold, the target time error difference threshold, or the positioning accuracy requirement can be used to request the TEG capability of the terminal under the corresponding TEG level identifier, target time error threshold, target time error difference threshold, or positioning accuracy requirement, such as whether the terminal supports the TEG and / or the number of supported TEGs and / or the statistical characteristics of the time error (difference).

[0156] Optionally, the request information is sent through at least one of the following:

[0157] Long Term Evolution Positioning Protocol LPP message;

[0158] New Radio Positioning Protocol NRPPa message;

[0159] Radio Resource Control RRC message;

[0160] Medium Access Control Element MAC CE message;

[0161] Downlink Control Information DCI;

[0162] Broadcast message.

[0163] Next, the method of sending request information is illustrated by examples: Case1: The request information can be directly sent from the location server LMF to the UE through the LPP message. Case2: The request information can be sent from the location server LMF to the serving gNB through NRPPa, and then sent from the serving gNB to the UE through at least one of signaling such as RRC, MAC CE, DCI or broadcast message.

[0164] Optionally, if the positioning accuracy requirement is low, such as lower than a preset positioning accuracy threshold, the request information can be default; and / or, if the network-side device expects that the UE only supports 1 TEG at the requested TEG level, or the UE only supports 1 TEG, or the UE does not support TEG, the request information can be default; and / or, if the configuration of the positioning reference signal (downlink positioning reference signal or uplink positioning reference signal bandwidth) meets a certain threshold, the request information can be default. Among them, the configuration of the positioning reference signal includes but is not limited to at least one of the following: bandwidth, positioning reference signal repetition, positioning reference signal subcarrier spacing, positioning reference signal period, etc. For example, when the configuration of the positioning reference signal is the positioning reference signal bandwidth, when the bandwidth of the positioning reference signal is less than a certain threshold, the request information can be default. The threshold can be determined by at least one of network indication, protocol agreement or terminal selection.

[0165] Under different positioning accuracy requirements, the TEG information provided by the UE may be different. For example: when the positioning accuracy requirement is not high, the UE may not provide the first indication information of the TEG, or the UE provides the first indication information of the TEG under a looser calibration; when the positioning accuracy requirement is high, the UE needs to provide the first indication information of the TEG under a stricter calibration. In order to avoid that the request message may not include the positioning accuracy requirement and the terminal cannot provide the applicable first indication information, therefore, optionally, before the terminal sends the first indication information, it further includes:

[0166] The terminal receives the positioning accuracy requirement of the first network-side device.

[0167] Here, the positioning accuracy requirement is used to assist the terminal in reporting the first indication information. The positioning accuracy requirement can be included in the Quality of Service Qos indication, and the Qos indication includes at least one of the positioning accuracy requirement, delay requirement and QoS category (LCS QoSclass). Therefore, the received positioning accuracy requirement can be used as the TEG level information to determine the first indication information. Optionally, the positioning accuracy requirement received by the terminal is applicable to at least one of the downlink positioning method (such as DL-TDOA positioning method), uplink positioning method (such as UL-TDOA positioning method), downlink+uplink positioning method (such as Multi-RTT positioning method).

[0168] Optionally, if the positioning accuracy requirement is low, such as lower than a preset positioning accuracy threshold, the terminal may not provide the first indication information; and / or, if the network device hopes that the UE only supports 1 TEG at the requested TEG level, or the UE only supports 1 TEG, or the UE does not support TEG, the terminal may not provide the first indication information; and / or, if the configuration of the positioning reference signal (downlink positioning reference signal or uplink positioning reference signal bandwidth) meets a certain threshold, the terminal may not provide the first indication information. The configuration of the positioning reference signal includes, but is not limited to, at least one of the following: bandwidth, positioning reference signal repetition, positioning reference signal subcarrier spacing, positioning reference signal period, etc. For example, when the configuration of the positioning reference signal is the positioning reference signal bandwidth, when the bandwidth of the positioning reference signal is less than a certain threshold, the request information can be default. The threshold can be determined by at least one of network indication, protocol agreement or terminal selection.

[0169] Optionally, the first indication information is further used to indicate the TEG level to which the TEG belongs.

[0170] In this way, when the first indication information indicates the association relationship between the uplink positioning reference signal and the TEG, and / or the association relationship between the positioning measurement result and the TEG, for the TEG in this association relationship, the TEG level to which it belongs is indicated. For example, when the request information includes a TEG level identifier and the first indication information of the TEG not lower than the level corresponding to the TEG level identifier is requested from the terminal, the TEG level to which the TEG belongs is indicated in the first indication information. If the terminal selects a certain TEG level that meets the requirements, the corresponding first indication information is provided.

[0171] In this embodiment, optionally, the first indication information is used to indicate the association relationship between the positioning measurement result and the TEG, and when the positioning measurement result is the time difference between transmission and reception, the TEG associated with the time difference between transmission and reception corresponds to one or more uplink positioning reference signal resources.

[0172] Here, the TEG associated with the time difference between transmission and reception is the UE RxTx TEG or {Rx TEG, Tx TEG}. When the positioning measurement result is the time difference between transmission and reception (Rx-Tx time difference), the terminal sends the first indication information to indicate the association relationship between the positioning measurement result and the UE RxTx TEG or {Rx TEG, Tx TEG}. Here, the UE RxTx TEG corresponds to one or more uplink positioning reference signal resources, or the Tx TEG in {Rx TEG, Tx TEG} corresponds to one or more uplink positioning reference signal resources.

[0173] Optionally, the one or more uplink positioning reference signal resources include at least one of the following:

[0174] Resources of the uplink positioning reference signal transmission occasion closest to the current measurement moment;

[0175] Resources of one or more preset uplink positioning reference signal transmission occasions;

[0176] Resources of one or more uplink positioning reference signal transmission occasions within the first time window.

[0177] Wherein, the current measurement moment is the moment corresponding to the Rx-Tx time difference measurement, or the current measurement moment corresponds to the Rx-Tx time difference measurement, or corresponds to an instance of the Rx-Tx time difference measurement, or corresponds to an instance of the PRS resource set associated with the Rx-Tx time difference measurement, or is the moment of Rx time or Tx time in the Rx-Tx time difference measurement.

[0178] Wherein, the transmission occasion can also be expressed in other ways such as transmission period, transmission instance, etc. Taking SRS as an example, it can be expressed as SRS transmission occasion, SRS occasion, SRS transmission instance, SRS instance, etc.

[0179] Optionally, for the uplink positioning reference signal transmission occasion closest to the current measurement, the uplink positioning reference signal transmission occasion closest to the current measurement can be determined before the current measurement moment; it can also be determined after the current measurement moment; it can also be not limited to before or after the current measurement moment. In this way, the uplink positioning reference signal transmission occasion closest to the current measurement can be before the current measurement moment or after the current measurement moment.

[0180] Optionally, the resources of one or more preset uplink positioning reference signal transmission occasions are determined by at least one of network indication, protocol convention, and terminal selection.

[0181] Optionally, the first time window can include the current measurement moment. That is, the first time window includes the Rx-Tx time difference measurement.

[0182] Optionally, the first time window can be determined by at least one of protocol convention, network indication, and terminal selection.

[0183] Optionally, one or more uplink positioning reference signal transmission opportunities within the first time window include at least one of the following:

[0184] One or more uplink positioning reference signal transmission opportunities within the first time window that are closest to the current measurement moment;

[0185] Specified uplink positioning reference signal transmission opportunities within the first time window;

[0186] Any uplink positioning reference signal transmission opportunities within the first time window.

[0187] Among them, one or more uplink positioning reference signal transmission opportunities within the first time window that are closest to the current measurement moment may be restricted before or after the current measurement moment, or may not be restricted before or after the current measurement moment. The same as the above content, it will not be elaborated here.

[0188] Optionally, the above-mentioned first time window is consistent (or the same, or related) with time window A. Among them, time window A is described as follows: When the gNB or TRP performs uplink measurement (such as measuring the uplink positioning reference signal), the network side device (such as the LMF) will configure time window A, and the gNB or TRP reports the measurement results within time window A (measurement results such as RTOA, UL RSRP, and / or gNB Rx - Tx time difference measurements, etc.). Among them, time window A includes at least 1 gNB / TRP measurement instance (gNB / TRP measurement instance), and each measurement instance includes at least 1 uplink positioning reference signal measurement opportunity (such as SRS measurement time occasions).

[0189] In this embodiment, optionally, the first indication information further includes the consistency indication information of the TEG, and the consistency indication information indicates whether the TEG information under the same TEG identifier at different moments is consistent.

[0190] For example, the consistency indication information may be: the TEG information under the same TEG identifier at different moments has changed, or the TEG information under the same TEG identifier cannot maintain consistency.

[0191] Here, the TEG information corresponding to the same TEG ID at different times has changed (i.e., the range / size of the timing error corresponding to the TEG under the same TEG identifier has changed), and the network cannot assume that the same TEG ID corresponds to the same TEG at different times. Or rather, the timing error of the TEG corresponding to the same TEG ID at different times has changed (or at least one of the size, range, and statistical characteristics of the timing error has changed). For example, the TEG 1 hour ago and the TEG 1 hour later cannot be regarded as the same TEG, even if the TEG ID is the same. Different times can be different measurement instances, measurement occasions, or different uplink positioning reference signal instances, occasions. Or adjacent measurement instances, measurement occasions, or adjacent uplink positioning reference signal instances, occasions.

[0192] Optionally, the consistency indication information of the TEG can also be indicated by other indication information, where the other indication information can be different from the first indication information. Optionally, the other indication information can be before or after the first indication information.

[0193] In this embodiment, optionally, within the time when the consistency of the TEG information is maintained, the first indication information further includes at least one of the following:

[0194] Change information about the association relationship between the positioning measurement result and the TEG;

[0195] Change information about the association relationship between the uplink positioning reference signal and the TEG.

[0196] Here, taking SRS as an example, the change information can be implemented as follows: the association of one or more SRS resources in 2 SRS instances with the Tx TEG has changed, such as the Tx TEG ID has changed. At SRS occasion X, SRS resource 0 is associated with Tx TEG0, and SRS resource 1 is associated with Tx TEG1; at SRS occasion X + 1, the Tx TEG associated with SRS has changed. For example, SRS resource 0 becomes associated with Tx TEG1, and SRS resource 1 becomes associated with Tx TEG0. Such a change in the TEG may be due to the UE switching the panel.

[0197] The time when the consistency of the TEG information is maintained is the effective time during which the TEG information under the same TEG identifier at different times is consistent.

[0198] That is to say, within the time when the consistency of the TEG information is maintained, the terminal indicates the change information of the association relationship between the positioning measurement result and the TEG, and / or the change information of the association relationship between the uplink positioning reference signal and the TEG. Or rather, within the time when the consistency of the TEG information is maintained, only the change of the association relationship of the TEG indicated by the terminal is effective. Or rather, the effective time for the terminal to indicate the change of the TEG association relationship is equal to or does not exceed the time when the consistency of the TEG information is maintained.

[0199] Optionally, the change information of the association relationship of the TEG can also be indicated by other indication information, where the other indication information can be different from the first indication information. Optionally, the other indication information can be before or after the first indication information.

[0200] Optionally, when the first indication information is used to indicate the association relationship between the positioning measurement result and the TEG, and the positioning measurement result is obtained based on the positioning reference signal measurement, the first indication information indicates the association relationship between the measurement results of multiple positioning reference signal resources under one TRP and at least one TEG; among the association relationships between the measurement results of multiple positioning reference signal resources under one TRP and at least one TEG, each TEG is associated with at least the measurement result of one positioning reference signal resource.

[0201] Here, the positioning measurement result is obtained based on the positioning reference signal measurement, and the positioning reference signal can be the downlink PRS.

[0202] Optionally, at least one of the following conditions is satisfied by the multiple positioning reference signal resources:

[0203] Belong to the same positioning reference signal resource set;

[0204] Belong to the same positioning frequency layer;

[0205] Fall within the range of the second time window;

[0206] The time distance is less than the distance threshold.

[0207] Here, the second time window is determined by at least one of network indication, protocol convention, and terminal selection. For example, multiple positioning reference signal resources are in the same measurement time window. The time distance being less than the distance threshold means that among the multiple positioning reference signal resources (such as PRS resources), the distance between the earliest PRS resource and the latest PRS resource is less than the distance threshold.

[0208] Applying the method of the embodiment of the present application, the terminal obtains at least one set of mapping relationships between the TEG level and the threshold of the timing error difference corresponding to the TEG level and the positioning service accuracy requirement in one of the ways of autonomous determination, protocol agreement, and network (pre)-configuration. The threshold of the timing error difference corresponding to the TEG level can be used by the UE to determine the TEG group, that is, if the timing error difference between two transmissions is less than (or does not exceed) this threshold, it can be considered that the timing errors of the two transmissions belong to one TEG.

[0209] Applying the method of the embodiment of the present application, the terminal can indicate the supported TEG level and the number of supported TEGs corresponding to the TEG level.

[0210] Applying the method of the embodiment of the present application, the terminal receives the request information sent by the network side, including: the TEG level identifier (TEG request instruction), the threshold of the TEG timing error difference, and the positioning service accuracy requirement. It is used to request the UE to provide the TEG information required by the network.
