Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a positioning method and a communication device. Background Art

[0002] The positioning methods of the terminal device include positioning technology based on measuring the arrival time and positioning technology based on measuring the arrival angle. Generally, the positioning accuracy of these positioning technologies is not high. At present, the carrier phase positioning technology is discussed in the third generation partnership project (3GPP) release 18 (release 18, R18). The carrier phase positioning technology is one of the main methods of high-precision positioning at present. It performs positioning by measuring the carrier phase change of the reference signal from the transmitter to the receiver. However, in the carrier phase positioning technology, taking downlink positioning as an example, the terminal device and the reference station (positioning reference unit, PRU) must simultaneously measure the reference signal sent by the base station to eliminate some time-varying error items, such as random initial phase error, clock drift, etc. The location management function (LMF) network element configures a time window for the terminal device and PRU, and instructs the terminal device and PRU to measure and report the downlink positioning reference signal resource set within the time window. At this time, the terminal device and PRU can measure the downlink reference signal at the same time. However, this time window configured by LMF is not only valid for carrier phase measurement, but also for time measurement, that is, downlink time measurement also needs to be measured and reported within the configured time window.

[0003] Normally, the terminal device is first roughly positioned based on the positioning technology based on the measurement time, and then the carrier phase positioning technology is further used to accurately locate the terminal device. LMF usually configures a maximum of two time windows for the terminal device and PRU. At this time, for downlink time measurement, only the resources within two time windows can be measured, resulting in too few reference signals that can be used for positioning. For positioning technology based on measurement time, the more measurable reference signals, the more measurement quantities can be obtained, and the overall positioning accuracy can be improved by smoothing or weighting. Therefore, only two time windows of reference signals will result in too few time measurements and low overall positioning accuracy.

[0004] Therefore, how to improve the positioning accuracy of terminal devices becomes a technical problem that needs to be solved. Summary of the invention

[0005] The present application provides a positioning method and proposes to add a new second indication information, which is used to indicate that the first device can not only measure the reference signal within the time window to determine the carrier phase measurement result, but also determine the time measurement result by measuring the reference signal on the time-frequency resource or the reference signal outside the time window, thereby improving the positioning accuracy of the terminal device.

[0006] On the first aspect, a positioning method is provided, which can be executed by an LMF network element, or can also be executed by a component of the LMF network element (such as a chip or circuit), without limitation.

[0007] The method includes: sending configuration information to the first device, the configuration information including time-frequency resources corresponding to a reference signal; sending first indication information and second indication information to the first device, wherein the first indication information is used to indicate information of a time window for measuring a reference signal, and the second indication information is used to indicate a measurement result of a carrier phase determined by measuring a reference signal within the time window; receiving a carrier phase measurement result and a time measurement result reported by the first device, wherein the time measurement result is determined by measuring the reference signal on the time-frequency resources; and determining the position of the terminal device based on the carrier phase measurement result and the time measurement result.

[0008] It should be understood that the number of reference signals on the time-frequency resources is usually greater than the number of reference signals configured in the time window. Therefore, the reference signal measured by the first device on the time-frequency resources will be greater than the reference signal measured only in the time window, so that the measurement result of the final determined time will be more accurate, thereby making the positioning of the terminal device more accurate.

[0009] In other words, in this application, in this method, the measurement result of time is independent of the time window. For example, the reference signal within the measured time window is only used to determine the measurement result of the carrier phase. For example, the measurement result of time may have been predetermined by a prior agreement on which reference signals should be measured to determine. For example, the terminal device selects the reference signal on the configured time-frequency resource, and then measures the selected reference signal to determine the measurement result of time.

[0010] In a possible implementation manner, the second indication information is further used to indicate a measurement result of determining the time by measuring a reference signal on the time-frequency resource.

[0011] Based on the above technical approach, in this application, the measurement result of the carrier phase can be decoupled from the measurement result of time, and the measurement result of time is independent of the configured time window, or in other words, the first device can measure the reference signal on the time-frequency resource within or outside the time window to determine the measurement result of time, which is related to the configured time-frequency resource. This increases the number of reference signals used to determine the measurement result of time, which can ensure the accuracy of positioning in the carrier phase positioning technology, as well as the accuracy of positioning in the positioning technology based on measuring time, thereby improving the overall positioning accuracy of the terminal device.

[0012] Alternatively, the method includes: sending configuration information to the first device, the configuration information including time-frequency resources corresponding to the reference signal; sending first indication information and second indication information to the first device, wherein the first indication information is used to indicate information of a time window for measuring the reference signal, and the second indication information is used to indicate priority measurement of the reference signal within the time window; receiving carrier phase measurement results and time measurement results reported by the first device, wherein the carrier phase measurement results and time measurement results are determined by measuring the reference signal within the time window and the reference signal outside the time window; and determining the position of the terminal device based on the carrier phase measurement results and the time measurement results.

[0013] It should be understood that in the present application, since the first device can measure both the reference signal within the time window and the reference signal outside the time window, the measured reference signal will be more than the reference signal measured only within the time window, and the final time measurement result will be more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0014] In other words, in the present application, the reference signal within the time window of priority measurement can be used only to determine the measurement result of the carrier phase, wherein the measurement result of the time can be determined based on the reference signal outside the measurement time window; or, the reference signal within the time window of priority measurement can be used to determine the measurement result of the carrier phase and the measurement result of the time, and the reference signal outside the time window can also be used to determine the measurement result of the time.

[0015] In a possible implementation, the method also includes: sending third indication information to the first device, the third indication information being used to indicate the priorities of different resources when measuring the reference signal within the time window, and / or the third indication information being used to indicate the priorities of different resources when measuring the reference signal outside the time window.

[0016] In the present application, in a possible implementation, the measurement result of the carrier phase is determined by measuring a reference signal within a time window, and the measurement result of time is determined by measuring a reference signal within the time window and a reference signal outside the time window.

[0017] In the present application, in another possible implementation, the measurement result of the carrier phase is determined by measuring a reference signal within a time window, and the time measurement result is determined by measuring a reference signal outside the time window.

[0018] Among them, "different resources" can be understood as the time-frequency resources corresponding to the reference signal, including the symbol or time slot or frame where the reference signal is located, etc., without limitation.

[0019] In one possible implementation, the method includes: sending third indication information to the first device, the third indication information being used to indicate an identifier of a reference signal resource and / or an identifier of a reference signal resource set measured when measuring a reference signal within a time window, and / or the third indication information being used to indicate an identifier of a reference signal resource and / or an identifier of a reference signal resource set measured when measuring a reference signal outside the time window.

[0020] Based on the above implementation method, in the present application, the first device can measure both the reference signal within the time window and the reference signal outside the time window. The measured reference signals will be more than the reference signals only measured within the time window, which will make the final time measurement result more accurate, thereby making the positioning accuracy of the terminal device higher.

[0021] Optionally, the method also includes: acquiring configuration information of a reference signal.

[0022] In the present application, the configuration information of the reference signal includes, for example, one or more of the following: the type or type set of the reference signal, the resource information of the reference signal, the sequence, the subcarrier spacing, the power, and the measurement request indication. Among them, the "reference signal type or type set" includes, for example, a zero power type reference signal and / or a non-zero power type reference signal. "Resource information of the reference signal" may include, for example, at least one of the following: a reference signal resource set, a time domain resource starting position, an interval or period between time domain resources, a symbol position, a symbol position set, a time domain pattern, time domain time window information, a frequency domain resource starting position, a frequency domain resource size, an interval or period between frequency domain resources, a frequency domain pattern, a corresponding relationship index between symbols and frequency domain patterns, a port index, a beam index, a basic time-frequency pattern or pattern index. Specifically, the information included in the configuration information of the reference signal can be found in the technical specification (technology specification, TS) 37.355 (describing the configuration of PRS) and TS38.455 (describing the configuration of SRS), which will not be described in detail in the present application.

[0023] In the present application, in one possible implementation, the first indication information and the second indication information may be carried in the same message. For example, the first indication information and the second indication information may be carried in the measurement request information, which is equivalent to the first indication information and the second indication information being sent simultaneously. In another possible implementation, the first information and the second information are different information, for example, the first indication information is carried in the measurement request message, and the second indication information may be carried in the auxiliary message (also referred to as the "positioning auxiliary message").

[0024] In the present application, the second indication information may be "1" bit indication information.

[0025] In the present application, reference signals may include, for example, reference signal resources and reference signal resource sets. Exemplarily, for example, reference signal resources may include: sounding reference signal SRS resources and / or positioning reference signal resources. Exemplarily, for example, reference signal resource sets may include sounding reference signal SRS resource sets and / or positioning reference signal PRS resource sets. Exemplarily, in downlink positioning scenarios, reference signals may be understood as PRS resource sets; and exemplary, in uplink positioning scenarios, reference signal resources may be understood as SRS resources.

[0026] In the present application, the measurement results of the carrier phase include: the carrier phase RSCP of the reference signal resource set and / or the carrier phase difference RSCPD of the reference signal resource set; the measurement results of the time include at least one of the following: relative arrival time RTOA, reference signal arrival time difference RSTD, transmit-receive time difference (Rx-Tx time difference) of the terminal device, and transmit-receive time difference (Rx-Tx time difference) of the base station.

[0027] In the present application, LMF can determine the information of the time window based on the configuration information. "The information of the time window" includes at least one of the following: the starting position of the time window, the length of the time window, the starting resource position of the reference signal in the time window, the interval between the reference signal resources in the time window, etc. It should be understood that the "time window" configured by LMF belongs to the time-frequency resource, or it can also be understood that a part of the time-frequency resource is the time window.

[0028] In this application, in the downlink positioning scenario, the first device can be understood as the terminal device and PRU; in the uplink positioning scenario, the first device can be understood as each base station involved in positioning. From the above introduction, it can be seen that usually there will be multiple base stations involved in positioning, and in a typical scenario, three base stations will participate in the positioning of the terminal device at the same time.

[0029] Alternatively, the method includes: sending configuration information to the first device, the configuration information including time-frequency resources corresponding to the reference signal; sending first indication information and second indication information to the first device, wherein the first indication information is used to indicate information of a time window for measuring the reference signal, and the second indication information is used to indicate a measurement result of a carrier phase determined by measuring the reference signal within the time window; receiving a carrier phase measurement result or a time measurement result reported by the first device, wherein the time measurement result is determined by measuring the reference signal on the time-frequency resources; and determining the position of the terminal device based on the carrier phase measurement result or the time measurement result.

[0030] Alternatively, the method includes: sending configuration information to the first device, the configuration information including time-frequency resources corresponding to the reference signal; sending first indication information and second indication information to the first device, wherein the first indication information is used to indicate information of a time window for measuring the reference signal, and the second indication information is used to indicate that the reference signal is measured preferentially within the time window; receiving a carrier phase measurement result or a time measurement result reported by the first device, wherein the carrier phase measurement result or the time measurement result is determined by measuring the reference signal within the time window and the reference signal outside the time window; and determining the position of the terminal device based on the carrier phase measurement result or the time measurement result.

[0031] It can also be understood that, in the present application, a bit indicator (e.g., second indication information) can be added to indicate whether the measurement within the indicated time window is only for RSCP / RCPD (e.g., the measurement result of the carrier phase), or whether the UE and PRU can measure the downlink (DL) PRS resource set outside the indicated time period.

[0032] Based on the above technical solution, in the present application, the measurement result of the carrier phase or the measurement result of the time can be flexibly determined through the second indication information, so as to determine the location of the terminal device.

[0091] In order to facilitate understanding of the technical solution provided by the present application, some professional terms and some positioning network elements involved in the present application are briefly introduced below.

[0092] 1. Resources

[0093] In the present application, "resources" may be frequency domain resources, time domain resources, resource blocks (RBs), physical resource blocks (PRBs), and the like. For example, data or information may be carried by time-frequency resources, wherein the "time-frequency resources" may include resources in the time domain and resources in the frequency domain. In the time domain, the time-frequency resources may include one or more time units. A time unit may be a symbol, or a mini-slot, or a slot, or a subframe, wherein the duration of a subframe in the time domain may be 1 millisecond (ms), a slot may consist of 7 or 14 symbols, and a mini-slot may include at least one symbol (e.g., 2 symbols, 4 symbols, or 7 symbols, or any number of symbols less than or equal to 14 symbols).

[0094] 2. Reference signal (RS)

[0095] The reference signal may also be called a pilot signal, which is a known signal provided by a transmitting device to a receiving device for channel estimation, channel measurement, channel detection or channel demodulation.

[0096] In the embodiment of the present application, the reference signal may be applied to the physical layer and does not carry data information from a higher layer. In addition, the reference signal may include a downlink reference signal and an uplink reference signal.

[0097] Among them, the downlink reference signal includes a cell-specific reference signal (CRS) for downlink, a terminal equipment-specific reference signal (UE-specific reference signal, UE-RS) for downlink, a channel state information reference signal (CSI-RS) for downlink channel measurement, a group-specific reference signal (GRS) for downlink, a positioning reference signal (PRS) for downlink, a beam reference signal (BRS) for downlink, a beam refinement reference signal (BRRS) for downlink, or a phase compensation reference signal (PCRS) for downlink, a path loss reference signal (PL-RS) for downlink, etc. Among them, the UE-RS for downlink is also called a demodulation reference signal (DMRS) for downlink. And a synchronization system / physical broadcast channel block (SS / PBCH block). Among them, the SS / PBCH block can be referred to as a synchronization signal block (synchronization signal block, SSB).

[0098] The uplink reference signal includes a demodulation reference signal (DMRS) for uplink demodulation, a sounding reference signal (SRS) for uplink channel measurement, or a PCRS for uplink, etc. Among them, the DMRS used for physical uplink control channel (PUCCH) demodulation is called PUCCH DMRS, and the DMRS used for physical uplink shared channel (PUSCH) demodulation is called PUSCH DMRS.

[0099] In addition to the reference signal, the reference signal of the present application may also be a sequence signal in a sequence signal set having good correlation characteristics. The good correlation characteristics are that any sequence in the set has a larger autocorrelation peak, and any two sequences in the set have a smaller mutual correlation peak. That is, in the embodiment of the present application, the transmitting device may transmit multiple signals, at least one of which is a sequence signal having the above-mentioned good correlation, such as a pseudorandom sequence and a Zadoff-chu sequence.

[0100] Specifically, correlation refers to the correlation calculation of a sequence signal with another sequence signal in the same set to obtain a correlation value. Therefore, for a sequence signal with good correlation characteristics, the receiving device can detect whether the signal exists based on the correlation. That is, there is no need to use a detection mechanism such as a pilot for the transmission of a sequence signal with correlation. Among them, as a signal with good correlation characteristics, a reference signal (or a pilot signal) can be listed.

[0101] It should be understood that the specific examples of sequence signals listed above are only for illustrative purposes and the present application is not limited thereto. For example, the sequence signal may also be a signal for carrying feedback information (e.g., confirmation (ACK) information or non-confirmation (NACK) information), a resource request signal, or a measurement request signal, etc.

[0109] UE-LMC is a component or application deployed on the UE with partial LMF functions, used to support positioning services on the PC5 port. UE-LMC is a possible deployment method.

[0110] As an emerging radio technology, new radio (NR) positioning can provide more value in enhancing positioning capabilities due to its unique properties. In the 3rd generation partnership project (3GPP) release 16 (release 18, R16), multiple positioning technologies such as downlink time difference of arrival (DL-TDOA), downlink angle of departure (DL-AOD), uplink time difference of arrival (UL-TDOA), uplink angle of arrival (UL-AOA), and multi-round trip time (multi-RTT) are supported. Among them, DL-TDOA, UL-TDOA and multi-RTT algorithms are positioning technologies based on measuring the arrival time, that is, the receiving end needs to measure the arrival time of the signal sent by the sending end, and then convert it into the distance information between the two, and finally obtain the position of the target to be located; DL-AOD and UL-AOA are positioning technologies based on measuring the arrival angle, that is, the receiving end measures the arrival angle of the reference signal sent by the sending end, and then infers the position of the receiving end based on the angle information between the receiving end and multiple senders with known positions. Generally speaking, the positioning accuracy of these positioning technologies is not high. The following briefly introduces the uplink positioning process using UL-TDOA technology as an example.

[0111] 1. Uplink positioning technology based on UL-TDOA

[0112] The base station measures the uplink reference signal, for example, measures the arrival time of the uplink sounding reference signal (SRS) sent by the user equipment (UE). The measurement process generally goes through the following steps: First, the LMF network element requests the SRS configuration information from the serving base station, the base station feeds back the SRS configuration information to the LMF, and sends the SRS configuration information to the UE, the LMF network element sends the SRS configuration information to other base stations participating in the positioning, and then the LMF requests the base station to measure, and after receiving the instruction from the LMF network element, the base station starts to receive the SRS sent by the UE and measures the arrival time of the SRS, and finally the base station reports the measurement result to the LMF network element, and the LMF estimates the position based on the received measurement result, thereby realizing the positioning of the target to be positioned.

[0113] The following is a brief introduction on how to calculate the position of the UE to be located based on the measurement results of LMF's UL-TDOA technology. Figure 1 Schematic diagram of UL-TDOA positioning. First, assume that the positions of the three base stations are known. Here, the coordinates of the i-th base station are defined as (x i ,y i ), the coordinates of the UE to be located are (x UE ,y UE ), and take one of the base stations as the reference base station, and assume that the arrival time of the SRS measured by the other two base stations (i.e., base station #1 and base station #2) is t i , then the arrival time difference between any one of the two base stations and the reference base station is Δt i1 According to the definition of a hyperbola (i.e., the distance to two fixed points is a constant), the target to be located is located on the hyperbola with two base stations as foci, and the following set of equations can be listed:

[0114]

[0115]

[0116] In the above two equations, c is the speed of light, because there are only two unknowns (x UE ,y UE ), the position coordinates of the target UE to be located can be obtained by combining equations (1) and (2). In fact, due to the existence of measurement errors, the above equations generally have no closed-form solutions. In engineering, classical optimization algorithms such as the least squares algorithm or the particle swarm filter algorithm are used to estimate the optimal solution of the above equations.

[0117] The 3GPP R18 standard version discusses carrier phase positioning technology, which is one of the main methods of high-precision positioning. It measures the distance with integer ambiguity by measuring the carrier phase change of the reference signal from the transmitter to the receiver. Taking the 3GHz RF signal as an example, the corresponding carrier wavelength is 0.1 meters. When the integer ambiguity of the carrier phase can be correctly solved, the carrier phase ranging accuracy can theoretically reach the centimeter to millimeter level, thus obtaining a high-precision positioning result.

[0118] Figure 2 This is a schematic diagram of carrier phase positioning. Figure 2 In the equation, “d” is the distance between the receiving end and the transmitting end; is the carrier phase measurement value; "N" represents the integer ambiguity, which is an integer, representing that N carrier cycles have passed; "λ" is the carrier wavelength. Distance d and carrier phase The following equation is satisfied:

[0119]

[0120] The 3GPP R17 standard version introduced a reference station (positioning reference unit, PRU) to assist in improving positioning performance. The reference station with a known position is used to measure the positioning reference signal, and a double difference equation is constructed between different base stations and between the positioning terminal and the reference station to eliminate the influence of non-ideal factors and improve positioning accuracy. R18 carrier phase positioning also supports the use of PRU to assist in carrier phase measurement and improve carrier phase positioning accuracy. The following briefly introduces the double difference carrier phase positioning method.

[0121] 2. Positioning technology based on double difference carrier phase

[0122] Figure 3 This is a schematic diagram of the double-difference carrier phase determination technology. Figure 3 In the example, the UE is adjacent to three base stations (BS1, BS2, and BS3) and one PRU. Assuming that both the UE and the base station have synchronization errors or phase errors, the phase measured by the UE or the base station can be expressed as:

[0123] The time synchronization error between UE and base station i, φ t is the random initial phase error of the UE, φ (i) is the random initial phase error of base station i, is the phase integer ambiguity between UE and base station i.

[0124] If equation (4) is understood as the phase measured by the base station, the random initial phase φ of the UE can be eliminated by making a difference between different base stations. t , we get the phase difference of arrival (PDOA):

[0125]

[0126] Similarly, for PRU, PDOA can be measured:

[0127]

[0128] By making a difference between UE and PRU, that is, subtracting equation (6) from equation (5), we can get the double difference PDOA:

[0129]

[0130] The random initial phase φ on the base station side can be eliminated (i) And the time synchronization error Δ t (ij) ,get Based on the information measured by multiple base stations, multiple double-difference PDOA measurement values ​​can be obtained, and the simultaneous equations can be used to calculate the UE position to be located based on the known PRU position and base station position.

[0131] Typically, a preliminary rough positioning of the UE is performed based on a positioning technology based on measuring the arrival time or the arrival angle, and then the carrier phase positioning technology is further used to accurately position the UE.

[0132] In carrier phase positioning technology, taking downlink positioning as an example, the terminal device and PRU must simultaneously measure the reference signal sent by the base station to eliminate some time-varying error terms, such as random initial phase error, clock drift, etc. The LMF network element configures a time window (time window) for the terminal device and PRU, and instructs the terminal device and PRU to measure and report the downlink reference signal resource set within the time window. At this time, the terminal device and PRU can measure the downlink reference signal at the same time. However, this time window configured by LMF is not only valid for carrier phase measurement, but also for time measurement. That is, the downlink time measurement also needs to be measured and reported within the configured time window. For this time window, the standard stipulates that the duration of this time window can be {1,2,4,6,8,12,16} time slots, and the configured time windows can be {1,2}. At this time, for downlink time measurement, only the reference signals within two time windows can be measured at most, such as Figure 4 As shown, the terminal device and PRU can measure the reference signals in time window #1 and time window #2 at the same time. As a result, the number of reference signal resource sets that can be used for positioning is too small. For new radio (NR) positioning, the more measurable resource sets there are, the more measurement quantities are obtained, and the overall positioning accuracy can be improved by smoothing or weighting. Therefore, only two reference signal resource sets for time measurement windows will result in too few time measurements and low overall positioning accuracy. Similar problems also exist in uplink positioning. If carrier phase positioning technology is used, each base station participating in the uplink positioning also needs to simultaneously measure the reference signal sent by the terminal device in order to eliminate some error terms that vary with time. Therefore, how to improve the positioning accuracy of the terminal device has become a technical problem that needs to be solved.

[0133] In view of this, the present application proposes a positioning technology that can adopt carrier phase positioning technology or positioning technology based on measurement time, so that the time measurement result is not only determined based on the reference signal within the measurement time window, but also based on the reference signal outside the measurement time window or the reference signal on the time-frequency resource. Since the number of measured reference signals is increased in the measurement result of determining the time, the overall positioning accuracy of the terminal device is improved.

[0134] Figure 5 is a system architecture diagram applicable to this application, Figure 5 The positioning network architecture based on the next-generation-radio access network (NG-RAN) is described. The core network function (access and mobility function, AMF) network element receives positioning service requests for a terminal device initiated by other network elements in the network. The AMF network element sends the received request to the LMF network element, which is responsible for processing the received positioning request and initiating related positioning procedures. The NG-RAN access network includes the 4G site NG-eNB and the 5G site gNB connected to the 5G core network. NG-RAN is responsible for sending and receiving reference signal resource sets and obtaining related measurement information. Figure 4 NG-C in the figure refers to the control plane interface. NG-eNB and 5G site gNB communicate through the Xn interface, and both NG-eNB and gNB include transmission points (TP). LMF network elements communicate with AMF network elements through the NLs interface, and LMF network elements are connected to the enhanced service mobile location center E-SMLC and SLP.

[0135] The Uu interface refers to the communication interface between the terminal and the base station, which can achieve reliable communication over long distances and a larger range. The NR-Uu communication system to which this application applies is as follows: Figure 6 As shown, the system includes a single or multiple network devices and a single or multiple terminal devices. A single network device can transmit data or control signaling to a single or multiple terminal devices, such as Figure 6 As shown in (a) in FIG. 1 , the same network device can transmit data or control signaling to terminal device #1 and terminal device #2 respectively, and multiple network devices can also transmit data or control signaling to a single terminal device at the same time. Figure 6 As shown in (b), network devices #1 to #3 can simultaneously transmit data or control signaling to terminal device #3.

[0136] The present application may also be applicable to a communication and positioning architecture based on a PC5 interface, where the PC5 interface is a direct communication interface, which refers to a communication interface between terminal devices, such as Figure 7 UE#1 and UE#2 can communicate through the PC5 interface, and can communicate with the (R)AN through the Uu interface. The (R)AN is connected to the LMF network element through the AMF network element.

[0137] Figure 8is a schematic flow chart of a positioning method 800 provided by the present application, such as Figure 8 As shown, the method includes:

[0138] Optionally, 810, the LMF network element obtains configuration information of the reference signal, where the configuration information includes time-frequency resources corresponding to the reference signal.

[0139] In the present application, the configuration information of the reference signal includes, for example, one or more of the following: the type or type set of the reference signal, the resource information of the reference signal, the sequence, the subcarrier spacing, the power, and the measurement request indication. Among them, the "reference signal type or type set" includes, for example, a zero power type reference signal and / or a non-zero power type reference signal. "Resource information of the reference signal" may include, for example, at least one of the following: a reference signal resource set, a time domain resource starting position, an interval or period between time domain resources, a symbol position, a symbol position set, a time domain pattern, time domain time window information, a frequency domain resource starting position, a frequency domain resource size, an interval or period between frequency domain resources, a frequency domain pattern, a corresponding relationship index between symbols and frequency domain patterns, a port index, a beam index, a basic time-frequency pattern or pattern index. Specifically, the information included in the configuration information of the reference signal can be found in the technical specification (technology specification, TS) 37.355 (describing the configuration of PRS) and TS38.455 (describing the configuration of SRS), which will not be described in detail in the present application.

[0140] In the present application, the reference signal may include, for example, a reference signal resource and a reference signal resource set. Exemplarily, for example, the reference signal resource may include: a sounding reference signal SRS resource. Exemplarily, for example, the reference signal resource set may include a positioning reference signal PRS resource set. Exemplarily, in a downlink positioning scenario, the reference signal may be understood as a PRS resource set; and exemplary, in an uplink positioning scenario, the reference signal resource set may be understood as an SRS resource set.

[0141] In the present application, the LMF network element can also obtain the location information of the service cell and / or the identifier of the service cell, which can assist the LMF network element in locating the terminal device.

[0142] In a possible implementation, taking downlink positioning as an example, the LMF network element may request configuration information from a serving base station (e.g., multiple base stations or multiple transmission and reception points (TRP)). Exemplarily, the LMF network element may send an information request message (e.g., gNB / TRPinformation request) to the serving base station, the request message is used to request configuration information, and the serving base station sends an information response (e.g., gNB / TRP information response) to the LMF network element, the response message carries the configuration information.

[0143] In another possible implementation, taking uplink positioning as an example, the LMF requests configuration information from the serving base station. Exemplarily, the LMF may send a positioning information request message (e.g., NRPPa Positioning information request) to the serving base station, and the serving base station determines the configuration information of the available reference signal (e.g., SRS resources), and sends the SRS configuration information to the terminal device and the PRU, and also sends a positioning information response message (e.g., NRPPa Positioning information response) to the LMF, and the response message carries the configuration information of the reference signal.

[0144] In another possible implementation, configuration information is pre-saved on the LMF network element. If positioning is required later, the previously saved configuration information can be directly used without requesting the configuration information from the base station.

[0145] In the downlink positioning scenario, before step 810, it also includes: the LMF network element obtains the capability information of the terminal device, and the capability information includes at least one of the following: the TDOA model of the terminal device, the measurement capability of the terminal device, and the multipath reporting capability of the terminal device. Exemplarily, the LMF sends a capability request message (e.g., Lpp CapabilityTransfer) to the terminal device to request the capability of the terminal device.

[0146] 820. The LMF network element sends the configuration information to the first device. Correspondingly, the first device receives the configuration information.

[0147] In this application, in the downlink positioning scenario, the first device can be understood as the terminal device and PRU; in the uplink positioning scenario, the first device can be understood as each base station involved in positioning. From the above introduction, it can be seen that usually there will be multiple base stations involved in positioning, and in a typical scenario, three base stations will participate in the positioning of the terminal device at the same time.

[0148] 830, the LMF network element sends first indication information and second indication information to the first device, wherein the first indication information is used to indicate information of a time window for measuring a reference signal, and the second indication information is used to indicate a measurement result of a carrier phase determined by measuring the reference signal within the time window.

[0149] Correspondingly, the first device receives the first indication information and the second indication information.

[0150] In one possible implementation, the LMF network element sends a measurement request message to the first device, where the measurement request message is used to request measurement of the reference signal, and the measurement request message includes first indication information and second indication information; in another possible implementation, a measurement request message is sent to the first device, where the measurement request message is used to request measurement of the reference signal, and the measurement request message includes first indication information; an auxiliary message is sent to the first device, where the auxiliary message includes second indication information.

[0151] In this application, "assistance message" may also be referred to as "positioning assistance message".

[0152] In the present application, in one possible implementation, the first indication information and the second indication information may be carried in the same message. For example, the first indication information and the second indication information may be carried in the measurement request information, which is equivalent to the first indication information and the second indication information being sent simultaneously. In another possible implementation, the first information and the second information are different information, for example, the first indication information is carried in the measurement request message, and the second indication information may be carried in the auxiliary message (also referred to as the "positioning auxiliary message").

[0153] Exemplarily, in uplink positioning, the measurement request message may be, for example, NRPPa measurementrequest. Exemplarily, in downlink positioning, the assistance message may be, for example, Request Location information.

[0154] In the present application, LMF can determine the information of the time window based on the configuration information. "The information of the time window" includes at least one of the following: the starting position of the time window, the length of the time window, the starting resource position of the reference signal in the time window, the interval between the reference signal resources in the time window, etc. Figure 4 As shown, the LMF can determine the time window based on the time-frequency resource corresponding to the reference signal in the configuration information. In the present application, the time window is located on the time-frequency resource, or it can also be understood that a part of the time-frequency resource is the time window.

[0155] In one possible implementation, the second indication information is used to indicate the measurement result of the carrier phase determined by measuring the reference signal within the time window, wherein the measurement result of the time is determined based on the reference signal on the measurement time-frequency resources. In other words, in this implementation, the measurement result of the time may not be constrained by the time window, and the first device may measure the time-frequency resources outside the time window to obtain the measurement result of the time. For example, the reference signal within the measured time window is only used to determine the measurement result of the carrier phase. For example, the measurement result of the time may have been predetermined by an agreement in advance as to which reference signals should be measured to determine it. For example, the terminal device selects the reference signal on the configured time-frequency resources, and then measures the selected reference signal to determine the measurement result of the time.

[0156] In another possible implementation, the second indication information is used to indicate that the reference signal is measured preferentially within the time window, wherein the measured reference signal includes a reference signal measured within the time window and a reference signal measured outside the time window, and the measured reference signal is used to determine the measurement result of the carrier phase and the measurement result of the time. In other words, in the present application, the reference signal within the time window can be used only to determine the measurement result of the carrier phase, and the measurement result of the time is determined by measuring the reference signal outside the time window; or, the reference signal within the time window can be used to determine the measurement result of the carrier phase and the measurement result of the time, and the reference signal outside the time window can also be measured to determine the measurement result of the time.

[0157] It should be understood that the number of reference signals on the time-frequency resources is usually greater than the number of reference signals configured in the time window. Therefore, the reference signals measured by the first device on the time-frequency resources will be greater than the reference signals measured only in the time window, so that the measurement result of the final determined time will be more accurate, thereby making the positioning accuracy of the terminal device higher. Alternatively, since the first device can measure both the reference signals in the time window and the reference signals outside the time window, the measured reference signals will be more than the reference signals measured only in the time window, which will also make the measurement result of the final determined time more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0158] In the present application, the measurement results of the carrier phase include: the measurement results of the carrier phase RSCP of the reference signal resource set and / or the measurement results of the carrier phase difference RSCPD of the reference signal resource set; the measurement results of the time include at least one of the following measurement results: relative arrival time RTOA, reference signal arrival time difference RSTD, transmit-receive time difference (Rx-Tx time difference) of the terminal device, and transmit-receive time difference (Rx-Tx time difference) of the base station.

[0159] Exemplarily, the second indication information may be designed as follows:

[0160] Method 1:

[0161] The second indication information is a 1-bit indication. When the value of the second indication information is "0", it means that the first device can only measure the reference signal within the indicated time window, thereby obtaining the measurement result of the carrier phase and the measurement result of the time. When the value of the second indication information is "1", the reference signal measured within the time window is used to determine the measurement result of the carrier phase. The first device can measure the reference signal received on the time-frequency resource corresponding to the reference signal configured by the configuration information, and use it to determine the measurement result of the time, without paying attention to whether the reference signal is within the time window, that is, the reference signal can be outside the time window. For another example, when the value of the second indication information is "1", it is only used to indicate that the reference signal measured within the time window is only used to determine the measurement result of the carrier phase. The measurement result of time can be determined by measuring which reference signals by prior agreement. Alternatively, the time measurement result can be determined based on the selected configured time-frequency resources.

[0162] Exemplarily, taking downlink positioning as an example, assuming that the LMF determines that the terminal device can measure six PRS resource sets based on the capabilities of the terminal device, and configures a time window for the first device (e.g., UE and PRU), which includes two PRS resource sets in total, then the first device can measure the four PRS resource sets included in the time window and use them to calculate the carrier phase measurement result. When determining the time measurement result, multiple PRS resource sets (e.g., four PRS resource sets) on the time-frequency resources corresponding to the reference signal can be measured.

[0163] In method 1, optionally, the second indication information is also used to indicate a measurement result of determining the time by measuring a reference signal on the time-frequency resource.

[0164] Based on the above technical approach, in the present application, the measurement result of the carrier phase can be decoupled from the measurement result of the time. The measurement result of the time is independent of the configured time window. In other words, the first device can measure the reference signal on the time-frequency resources within or outside the time window to determine the measurement result of the time, which is related to the configured time-frequency resources. This increases the number of reference signals used to determine the measurement result of the time, which can ensure the accuracy of positioning in the carrier phase positioning technology, as well as the accuracy of positioning in the positioning technology based on measuring time, thereby improving the overall positioning accuracy of the terminal device.

[0165] Method 2:

[0166] The second indication information is a 1-bit indication. When the value of the second indication information is "0", it indicates that the first device can only measure the reference signal within the indicated time window, thereby obtaining the measurement result of the carrier phase and the measurement result of the time. When the value of the second indication information is "1", it indicates that the first device preferentially measures the configured reference signal within the indicated time window, and can also measure the reference signal configured outside the window, thereby obtaining the measurement result of the carrier phase and the measurement result of the time.

[0167] It should be understood that in the present application, in a possible implementation method, the LMF network element obtains the capability of the terminal device, and can determine the number of reference signals to be measured for the terminal device based on the capability of the terminal device. Exemplarily, taking downlink positioning as an example, assuming that the LMF determines that the terminal device can measure four PRS resource sets based on the capability of the terminal device, if the time window includes a total of two PRS resource sets, and there are multiple PRS resource sets outside the time window, at this time, the first device can preferentially measure the two PRS resource sets within the time window, and then measure any two PRS resource sets outside the time window. Alternatively, it can also be understood that in mode 2, if the value of the second indication information is "1", it indicates that the reference signal is measured not only within the time window, but also outside the time window.

[0168] In method 2, optionally, the method also includes: the LMF network element sends a third indication information to the first device, the third indication information is used to indicate the priorities of different resources when measuring the reference signal within the time window, and / or the third indication information is used to indicate the priorities of different resources when measuring the reference signal outside the time window.

[0169] The "different resources" may be understood as symbols or time slots or frames corresponding to the reference signal, etc., without limitation. For specific understanding of the resources, please refer to the above-mentioned introduction.

[0170] In the second mode, optionally, the method further includes: the LMF network element sends a third indication information to the first device, the third indication information is used to indicate the reference signal resource identifier and / or the reference signal resource set identifier measured when measuring the reference signal within the time window, and / or, the third indication information is used to indicate the reference signal resource identifier and / or the reference signal resource set identifier measured when measuring the reference signal outside the time window. It can also be understood that the third indication information can indicate which reference signals within the measurement time window and / or which reference signals outside the measurement time window.

[0171] Exemplarily, assuming that the LMF determines that the terminal device can measure four PRS resource sets based on the capability of the terminal device, and assuming that the LMF configures a time window for the terminal device, taking downlink positioning as an example, the time window includes two PRS resource sets, namely PRS resource set #1 and PRS resource set #2. At this time, the LMF can also send a third indication information to the first device, and the third indication information is used to indicate (2,1), which means that PRS resource set #2 in the time window can be measured first, and then PRS resource set #1 in the time window can be measured.

[0172] Exemplarily, assuming that there are two PRS resource sets outside the time window, namely PRS resource set #3 and PRS resource set #4. At this time, the third indication information can be used to indicate (3,4), which means that PRS resource set #3 outside the time window is measured first, and then PRS resource set #4 outside the time window is measured.

[0173] In a possible implementation, the third indication information may also simultaneously indicate the identifier of the reference signal resource set measured within the time window and the identifier of the reference signal resource set measured outside the time window. Exemplarily, the third indication information may indicate a list, for example, the list is {(2,1)(3,4)}, which means that when measuring the reference signal within the time window, PRS resource set #2 may be measured first, and then PRS resource set #1 may be measured, and when measuring the reference signal outside the time window, PRS resource set #3 may be measured first, and then PRS resource set #4 may be measured.

[0174] It can also be understood that in the present application, a bit indicator (e.g., second indication information) may be added to indicate whether the measurement within the indicated time window is only for RSCP / RCPD (e.g., the measurement result of the carrier phase), or whether the UE and PRU can measure the downlink (DL) PRS resource set outside the indicated period.

[0175] Based on the above implementation method, in the present application, the first device can measure both the reference signal within the time window and the reference signal outside the time window. The measured reference signals will be more than the reference signals only measured within the time window, which will make the final time measurement result more accurate, thereby making the positioning accuracy of the terminal device higher.

[0176] 840. The first device measures the reference signal according to the configuration information, the first indication information, and the second indication information, and determines a measurement result of a carrier phase and / or a measurement result of time.

[0177] In a possible implementation, in a downlink positioning scenario, based on the configuration information, the serving base station sends a reference signal resource set to the terminal device and the PRU, and the terminal device and the PRU receive the reference signal resource set based on the configuration information of the reference signal, and measure the reference signal resource set based on the first indication information and the second indication information, thereby obtaining a carrier phase measurement result and / or a time measurement result. Exemplarily, based on the configuration information, the serving base station may periodically send a reference signal resource set or non-periodically send a reference signal resource set. For the specific measurement method, please refer to the example of step 840 above, which will not be repeated here.

[0178] In another possible implementation, in the uplink positioning scenario, the serving base station sends configuration information to the terminal device (or, may also send configuration information to the PRU), and the terminal device (or, may also include the PRU) sends reference signal resources to each base station participating in the positioning based on the configuration information. At this time, each base station may receive the reference signal resources based on the configuration information, and measure the reference signal resources based on the first indication information and the second indication information, thereby obtaining the measurement results of the carrier phase and / or the measurement results of the time. The specific measurement method can refer to the example of step 850 above, which will not be repeated here.

[0179] In a possible implementation manner, the first device measures the reference signal according to the configuration information, the first indication information, the second indication information, and the third indication information, and determines a measurement result of a carrier phase and / or a measurement result of time.

[0180] 850. The first device reports the measurement result of the carrier phase and / or the measurement result of the time to the LMF.

[0181] Correspondingly, the LMF receives the carrier phase measurement result and / or time measurement result reported by the first device.

[0182] In a possible implementation, in a downlink positioning scenario, the UE and the PRU may report the measurement results to the LMF. Exemplarily, the UE and the PRU may send a Provide Location Information message to the LMF, which carries the measurement results of the carrier phase and the time.

[0183] In another possible implementation, in an uplink positioning scenario, each base station involved in positioning may report a measurement result to the LMF. For example, each base station involved in positioning sends a measurement response message (NRPPa measurementresponse) to the LMF, and the response message carries the measurement result.

[0184] 860, LMF determines the location of the terminal device based on the measurement result of the carrier phase and / or the measurement result of time.

[0185] In a possible implementation, the LMF determines the location of the terminal device based on the measurement results of the carrier phase and / or the measurement results of the time, as well as the location information of the serving cell.

[0186] In another possible implementation, the LMF determines the location of the terminal device based on the measurement results of the carrier phase and / or the measurement results of the time, the location information of the serving cell, and the location information of the PRU.
