Description

Positioning method and communication device

[0001] This application claims priority to the Chinese patent application with application number 202311282030.1 filed with the State Intellectual Property Office of China on September 27, 2023, and priority to the Chinese patent application with the invention name “A Positioning Method and Communication Device”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more specifically, to a positioning method and a communication device. Background Art

[0003] Terminal device positioning methods include those based on time of arrival (TOA) and angle of arrival (AOA). These positioning techniques typically lack high accuracy. Currently, carrier phase positioning (CPP) is discussed in Release 18 (R18) of the 3rd Generation Partnership Project (3GPP). CPP is one of the primary methods for high-precision positioning. It performs positioning by measuring the carrier phase variation of a reference signal from the transmitter to the receiver. However, in CPP, for example, in downlink positioning, the terminal device and the positioning reference unit (PRU) must simultaneously measure the reference signal sent by the base station to eliminate time-varying error terms, such as random initial phase error and clock drift. The location management function (LMF) network element configures a time window for the terminal device and PRU, and instructs them to measure and report the downlink positioning reference signal resource set within that time window. This allows the terminal device and PRU to simultaneously measure the downlink reference signal. However, the 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 this configured time window.

[0004] Typically, a terminal device is initially roughly located using positioning technology based on measurement time, and then the terminal device's position is precisely located using carrier phase positioning technology. LMF typically configures a maximum of two time windows for the terminal device and PRU. In this case, for downlink time measurement, only resources within two time windows can be measured, resulting in too few reference signals available for positioning. For positioning technology based on measurement time, the more measurable reference signals there are, the more measurements are obtained, and the overall positioning accuracy can be improved through smoothing or weighting. Therefore, having only two time windows of reference signals will result in too few time measurements and low overall positioning accuracy.

[0005] Therefore, how to improve the positioning accuracy of terminal devices has become a technical problem that needs to be solved.

[0006] Summary of the Invention

[0007] 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.

[0008] 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.

[0009] 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 the carrier phase measurement result and the 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.

[0010] 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 accuracy of the terminal device higher.

[0011] In other words, in this application, in this method, the time measurement result is independent of the time window. For example, the reference signal within the measured time window is only used to determine the carrier phase measurement result. For example, the time measurement result may have a pre-defined agreement on which reference signals should be measured. For example, the terminal device selects a reference signal on the configured time-frequency resource and then measures the selected reference signal to determine the time measurement result.

[0012] In a possible implementation manner, the second indication information is further used to indicate a measurement result of determining time by measuring a reference signal on the time-frequency resource.

[0013] 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. The measurement result of time is independent of the configured time window. 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.

[0014] 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.

[0015] 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 signals will be more than the reference signals measured only within the time window, and the measurement results of the final determined time will be more accurate, thereby improving the overall positioning accuracy of the terminal device as a whole.

[0016] 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 time window of measurement; 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 time, and the reference signal outside the time window can also be used to determine the measurement result of time.

[0017] In one possible implementation, the method further 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.

[0018] In the present application, in a possible implementation, the measurement result of the carrier phase is determined by measuring the reference signal within the time window, and the measurement result of the time is determined by measuring the reference signal within the time window and the reference signal outside the time window.

[0019] 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.

[0020] Here, “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.

[0021] 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 measured reference signal resource and / or an identifier of a reference signal resource set when measuring a reference signal within a time window, and / or the third indication information being used to indicate an identifier of a measured reference signal resource and / or an identifier of a reference signal resource set when measuring a reference signal outside a time window.

[0022] Based on the above implementation method, in this 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 measured only within the time window, which will make the final time measurement result more accurate, thereby making the positioning accuracy of the terminal device higher.

[0023] Optionally, the method further includes: acquiring configuration information of a reference signal.

[0024] 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 reference signal and / or a non-zero-power reference signal. The "reference signal resource information" 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, an index of the correspondence 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 (TS) 37.355 (describing the configuration of the PRS) and TS 38.455 (describing the configuration of the SRS), and will not be described in detail in this application.

[0025] 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 a measurement request message, which is equivalent to the first indication information and the second indication information being issued simultaneously. In another possible implementation, the first information and the second information are different information. For example, the first indication information is carried in a measurement request message, and the second indication information may be carried in an assistance message (also referred to as a "positioning assistance message").

[0026] In the present application, the second indication information may be "1" bit indication information.

[0027] In this application, reference signals may include, for example, reference signal resources and reference signal resource sets. For example, reference signal resources may include: sounding reference signal (SRS) resources and / or positioning reference signal (PRS) resources. For example, reference signal resource sets may include: sounding reference signal (SRS) resource sets and / or positioning reference signal (PRS) resource sets. For example, in downlink positioning scenarios, reference signals may be understood as PRS resource sets; and in uplink positioning scenarios, reference signal resources may be understood as SRS resources.

[0028] In this 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.

[0029] In this application, the LMF can determine time window information based on the configuration information. "Time window information" 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 within the time window, the interval between reference signal resources within the time window, etc. It should be understood that the "time window" configured by the LMF belongs to the time-frequency resource, or it can also be understood that a portion of the time-frequency resource is the time window.

[0030] 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. As can be seen from the above introduction, there are usually 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.

[0031] Alternatively, the method includes: sending configuration information to the first device, the configuration information including the 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 the time window for measuring the reference signal, and 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; receiving the carrier phase measurement result or 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.

[0032] 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 a carrier phase measurement result or a time measurement result reported from 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.

[0033] 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.

[0034] Based on the above technical solution, in this application, the measurement result of the carrier phase or the measurement result of the time can be flexibly determined through the second indication information, thereby determining the location of the terminal device.

[0093] In order to facilitate understanding of the technical solution provided by this application, the following first briefly introduces some professional terms and some positioning network elements involved in this application.

[0094] 1. Resources

[0095] 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, 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).

[0096] 2. Reference signal (RS)

[0097] The reference signal, also known as a pilot signal, is a known signal provided by a transmitting device to a receiving device for channel estimation, channel measurement, channel detection, or channel demodulation.

[0098] 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. Furthermore, the reference signal may include a downlink reference signal and an uplink reference signal.

[0099] Among them, downlink reference signals include the cell-specific reference signal (CRS) for downlink, the terminal equipment-specific reference signal (UE-RS) for downlink, the channel state information reference signal (CSI-RS) for downlink channel measurement, the group-specific reference signal (GRS) for downlink, the positioning reference signal (PRS) for downlink, the beam reference signal (BRS) for downlink, the beam refinement reference signal (BRRS) for downlink, or the phase compensation reference signal (PCRS) for downlink, the pathloss reference signal (PL-RS) for downlink, etc. Among them, the UE-RS for downlink is also called the demodulation reference signal (DMRS) for downlink. And the synchronization system / physical broadcast channel block (SS / PBCH block). Among them, the SS / PBCH block can be simply referred to as a synchronization signal block (synchronization signal block, SSB).

[0100] Uplink reference signals include the demodulation reference signal (DMRS) used for uplink demodulation, the sounding reference signal (SRS) used for uplink channel measurement, and the uplink PCRS, 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.

[0101] In addition to the reference signal, the reference signal of the present application may also be a sequence signal from a set of sequence signals with good correlation characteristics. The good correlation characteristics are that any sequence in the set has a large autocorrelation peak, and any two sequences in the set have small cross-correlation peaks. That is, in the embodiments of the present application, the transmitting device may transmit multiple signals, at least one of which is a sequence signal with the above-mentioned good correlation, such as a pseudorandom sequence or a Zadoff-Chu sequence.

[0102] Specifically, correlation refers to calculating the correlation between a sequence signal and another sequence signal in the same set, resulting in a correlation value. Therefore, for sequence signals with good correlation characteristics, a receiving device can detect the presence of the signal based on the correlation. In other words, the transmission of sequence signals with good correlation does not require the use of detection mechanisms such as pilot signals. One example of a signal with good correlation characteristics is a reference signal (or pilot signal).

[0103] It should be understood that the specific examples of sequence signals listed above are only illustrative and the present application is not limited thereto. For example, the sequence signal may also be a signal for carrying feedback information (e.g., acknowledgment (ACK) information or non-acknowledgment (NACK) information), a resource request signal, or a measurement request signal.

[0109] SLP is a network element, module or component in the 4G core network that processes the user plane security positioning protocol.

[0110] 6. User equipment location management control (UE-LMC) module

[0111] 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.

[0112] As an emerging radio technology, new radio (NR) positioning offers unique advantages that can enhance positioning capabilities. 3rd Generation Partnership Project (3GPP) Release 16 (R16) supports multiple positioning technologies, including 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). DL-TDOA, UL-TDOA, and multi-RTT algorithms are positioning technologies based on time-of-arrival measurements. This requires the receiver to measure the arrival time of the signal sent by the transmitter, convert it into distance information, and ultimately determine the location of the target. DL-AOD and UL-AOA are positioning technologies based on angle-of-arrival measurements. This means the receiver measures the angle of arrival of a reference signal sent by the transmitter and then infers the receiver's location based on the angle information between the receiver and multiple transmitters with known locations. These positioning technologies generally have low accuracy. The following briefly describes the uplink positioning process using UL-TDOA as an example.

[0113] 1. Uplink Positioning Technology Based on UL-TDOA

[0114] The base station measures uplink reference signals, such as the arrival time of the uplink sounding reference signal (SRS) sent by the user equipment (UE). The measurement process generally involves the following steps: First, the LMF network element requests SRS configuration information from the serving base station. The base station feeds the SRS configuration information back 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 positioning. The LMF then requests measurement from the base station. After receiving the instruction from the LMF network element, the base station begins to receive the SRS sent by the UE and measures the arrival time of the SRS. Finally, the base station reports the measurement results to the LMF network element. The LMF estimates the position based on the received measurement results, thereby locating the target to be positioned.

[0115] The following briefly introduces how LMF calculates the position of the UE to be located based on the measurement results of UL-TDOA technology. Figure 1 is a 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 constant), the target to be located is located on the hyperbola with the two base stations as the focus, and the following set of equations can be listed:

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

[0117] The 3GPP Release 18 standard discusses carrier phase positioning technology, a key method for high-precision positioning. It measures distances with integer ambiguities by measuring the carrier phase variation of a reference signal from the transmitter to the receiver. For example, using a 3 GHz RF signal, the corresponding carrier wavelength is 0.1 meters. By correctly resolving the integer ambiguities of the carrier phase, theoretically, carrier phase ranging accuracy can reach centimeters to millimeters, resulting in high-precision positioning results.

[0118] FIG2 is a schematic diagram of carrier phase positioning, where “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. The following equation is satisfied:

[0119] The 3GPP Release 17 standard introduced positioning reference units (PRUs) to aid in improving positioning performance. Using reference stations with known locations to measure positioning reference signals, double-difference equations are constructed between base stations and between the positioning terminal and the reference stations. This eliminates the influence of non-ideal factors and improves positioning accuracy. Release 18 also supports the use of PRUs to assist in carrier phase measurement, improving carrier phase positioning accuracy. The following briefly describes the double-difference carrier phase positioning method.

[0120] 2. Positioning technology based on double-difference carrier phase

[0121] Figure 3 is a schematic diagram of the double-difference carrier phase determination technology. In Figure 3, a UE is adjacent to three base stations (BS1, BS2, and BS3) and a PRU. Assuming that both the UE and the base station have synchronization errors or phase errors, the phase measured by the UE or base station can be expressed as:

[0122] Time synchronization error with base station i, φ t is the random initial phase error of the UE, is the random initial phase error of base station i, is the phase integer ambiguity between UE and base station i.

[0123] 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):

[0124] Similarly for PRU, PDOA can be measured:

[0125] By making a difference between the UE and the PRU, that is, subtracting the formula (6) from the formula (5), we can get the double difference PDOA:

[0126] The random initial phase φ on the base station side can be eliminated (i) and 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. The simultaneous equations can be used to calculate the UE position to be located based on the known PRU position and base station position.

[0127] Typically, a preliminary coarse positioning of the UE is performed based on a positioning technology that measures the arrival time or the arrival angle, and then a carrier phase positioning technology is further used to accurately position the UE.

[0128] 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 time-varying errors such as random initial phase error and clock drift. The LMF network element configures a time window for the terminal device and PRU and instructs them to measure and report the downlink reference signal resource set within this time window. This allows the terminal device and PRU to simultaneously measure the downlink reference signal. However, this LMF-configured time window applies not only to carrier phase measurements but also to time measurements. That is, downlink time measurements must also be measured and reported within this configured time window. The standard specifies that this time window can last for {1, 2, 4, 6, 8, 12, 16} time slots, and that a maximum of {1, 2} time windows can be configured. For downlink time measurements, only reference signals within two time windows can be measured. As shown in Figure 4, the terminal device and PRU can simultaneously measure reference signals within time window #1 and time window #2. 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 can be obtained, and the overall positioning accuracy can be improved by smoothing or weighting. Therefore, a reference signal resource set with only two time measurement windows will result in too few time measurements and low overall positioning accuracy. A similar problem also exists 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.

[0129] 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 the determined time, the overall positioning accuracy of the terminal device is improved.

[0130] Figure 5 is a system architecture diagram applicable to the present application, which describes the positioning network architecture based on the next-generation radio access network (NG-RAN). The core network function (access and mobility function, AMF) network element receives a positioning service request 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 the relevant positioning process. The NG-RAN access network includes a 4G site NG-eNB and a 5G site gNB connected to the 5G core network. The NG-RAN is responsible for sending and receiving reference signal resource sets and obtaining relevant measurement information. The NG-C in Figure 4 refers to the control plane interface. The NG-eNB and the 5G site gNB communicate through the Xn interface, and both the NG-eNB and the gNB include a transmission point (TP). The LMF network element and the AMF network element communicate through the NLs interface. The LMF network element is connected to the enhanced serving mobility location center E-SMLC and the SLP.

[0131] 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 applicable to this application is shown in Figure 6, which includes a single or multiple network devices, as well as a single or multiple terminal devices. A single network device can transmit data or control signaling to a single or multiple terminal devices. As shown in (a) in Figure 6, the same network device can transmit data or control signaling to terminal device #1 and terminal device #2 respectively. Multiple network devices can also transmit data or control signaling to a single terminal device at the same time. As shown in (b) in Figure 6, network devices #1 to #3 can simultaneously transmit data or control signaling to terminal device #3.

[0132] This application can also be applied to the communication and positioning architecture based on the PC5 interface. The PC5 interface is a direct communication interface, which refers to the communication interface between terminal devices, as shown in 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.

[0133] FIG8 is a schematic flow chart of a positioning method 800 provided by the present application. As shown in FIG8 , the method includes:

[0134] 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.

[0135] 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 reference signal and / or a non-zero-power reference signal. The "reference signal resource information" 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, an index of the correspondence 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 (TS) 37.355 (describing the configuration of the PRS) and TS 38.455 (describing the configuration of the SRS), and will not be described in detail in this application.

[0136] In this application, reference signals may include, for example, reference signal resources and reference signal resource sets. For example, reference signal resources may include Sounding Reference Signal (SRS) resources. For example, reference signal resource sets may include Positioning Reference Signal (PRS) resource sets. For example, in downlink positioning scenarios, reference signals may be understood as PRS resource sets; and in uplink positioning scenarios, reference signal resource sets may be understood as SRS resource sets.

[0137] In this application, the LMF network element can also obtain the location information and / or identification of the service cell, which can assist the LMF network element in locating the terminal device.

[0138] In one possible implementation, taking downlink positioning as an example, the LMF network element may request configuration information from a serving base station (e.g., which may be multiple base stations or multiple transmission and reception points (TRPs)). Exemplarily, the LMF network element may send an information request message (e.g., gNB / TRP information request) to the serving base station, requesting configuration information. The serving base station sends an information response (e.g., gNB / TRP information response) to the LMF network element, carrying the configuration information.

[0139] 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. 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. At the same time, the LMF also sends a positioning information response message (e.g., NRPPa Positioning information response) to the LMF. The response message carries the configuration information of the reference signal.

[0140] 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 configuration information from the base station.

[0141] In the downlink positioning scenario, before step 810, the following further includes: the LMF network element obtains capability information of the terminal device, where 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 Capability Transfer) to the terminal device to request the capabilities of the terminal device.

[0142] 820. The LMF network element sends the configuration information to the first device. Correspondingly, the first device receives the configuration information.

[0143] 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. As can be seen from the above introduction, there are usually 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.

[0144] 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 a reference signal within the time window.

[0145] Correspondingly, the first device receives the first indication information and the second indication information.

[0146] 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, the 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; and the auxiliary message is sent to the first device, where the auxiliary message includes second indication information.

[0147] In this application, the "assistance message" may also be referred to as a "positioning assistance message".

[0148] 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 a measurement request message, which is equivalent to the first indication information and the second indication information being issued simultaneously. In another possible implementation, the first information and the second information are different information. For example, the first indication information is carried in a measurement request message, and the second indication information may be carried in an assistance message (also referred to as a "positioning assistance message").

[0149] Exemplarily, in uplink positioning, the measurement request message may be, for example, NRPPa measurement request. Exemplarily, in downlink positioning, the assistance message may be, for example, Request Location information.

[0150] In this application, the LMF can determine time window information based on configuration information. "Time window information" 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 within the time window, the interval between reference signal resources within the time window, etc. As shown in Figure 4, the LMF can determine the time window based on the time-frequency resources corresponding to the reference signals in the configuration information. In this application, the time window is located on the time-frequency resource, or it can also be understood that a portion of the time-frequency resource is the time window.

[0151] 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 time measurement result is determined based on the reference signal on the time-frequency resource. In other words, in this implementation, the time measurement result 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 time measurement result. 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 time measurement result may have been predetermined by the agreement on which reference signals should be measured to determine it. 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 time measurement result.

[0152] 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, while 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.

[0153] 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 within 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.

[0154] 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 the measurement results of 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.

[0155] For example, the second indication information may be designed as follows:

[0156] Method 1:

[0157] 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", 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 having to pay 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 agreement in advance. Alternatively, the time measurement result can be determined based on the selected configured time-frequency resources.

[0158] 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 (for example, 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 (for example, four PRS resource sets) on the time-frequency resources corresponding to the reference signal can be measured.

[0159] In the first approach, optionally, the second indication information is further used to indicate a measurement result of determining time by measuring a reference signal on a time-frequency resource.

[0160] Based on the above technical approach, in this application, the measurement results of the carrier phase can be decoupled from the measurement results of time. The measurement results of time are 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 results of time, which is related to the configured time-frequency resources. This increases the number of reference signals used to determine the measurement results 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.

[0161] Method 2:

[0162] 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 to obtain carrier phase measurement results and time measurement results. 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 to obtain carrier phase measurement results and time measurement results.

[0163] It should be understood that in the present application, in one possible implementation, 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 there are two PRS resource sets in the time window, and there are multiple PRS resource sets outside the time window, then the first device can give priority to measuring the two PRS resource sets in 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.

[0164] 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 priority of different resources when measuring the reference signal within the time window, and / or, the third indication information is used to indicate the priority of different resources when measuring the reference signal outside the time window.

[0165] The term "different resources" may be understood as symbols, time slots, or frames corresponding to reference signals, etc., without limitation. For more information on resources, please refer to the aforementioned description.

[0166] In the second approach, optionally, the method further includes: the LMF network element sending third indication information to the first device, where the third indication information is used to indicate an identifier of a reference signal resource and / or an identifier of a reference signal resource set to be measured when measuring a reference signal within a time window, and / or the third indication information is used to indicate an identifier of a reference signal resource and / or an identifier of a reference signal resource set to be measured when measuring a reference signal outside the time window. It can also be understood that the third indication information may indicate which reference signals within the measurement time window and / or which reference signals outside the measurement time window are to be measured.

[0167] For example, assuming that the LMF determines that the terminal device can measure four PRS resource sets based on the capabilities 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. The third indication information is used to indicate (2,1), which means that the PRS resource set #2 in the time window can be measured first, and then the PRS resource set #1 in the time window can be measured.

[0168] For example, assuming that there are two PRS resource sets outside the time window, namely PRS resource set #3 and PRS resource set #4, then 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.

[0169] In a possible implementation, the third indication information may also simultaneously indicate the identifiers of the reference signal resource sets measured within the time window and the identifiers of the reference signal resource sets measured outside the time window. Exemplarily, the third indication information may indicate a list, for example, the list is {(2,1)(3,4)}, which indicates that when measuring the reference signal within the time window, PRS resource set #2 may be measured first, followed by PRS resource set #1; and when measuring the reference signal outside the time window, PRS resource set #3 may be measured first, followed by PRS resource set #4.

[0170] 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.

[0171] Based on the above implementation method, in this 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 measured only within the time window, which will make the final time measurement result more accurate, thereby making the positioning accuracy of the terminal device higher.

[0172] 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 the carrier phase and / or a measurement result of the time.

[0173] In one 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. 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 measurement result of the carrier phase and / or a measurement result of time. Exemplarily, based on the configuration information, the serving base station may periodically send a reference signal resource set or aperiodically send a reference signal resource set. For the specific measurement method, please refer to the example of step 840 above and will not be repeated here.

[0174] In another possible implementation, in the uplink positioning scenario, the serving base station sends configuration information to the terminal device (or, it may also send configuration information to the PRU), and the terminal device (or, it 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 can 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 time measurement results. The specific measurement method can be found in the example of step 850 above and will not be repeated here.

[0175] 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 the carrier phase and / or a measurement result of time.

[0176] 850. The first device reports the carrier phase measurement result and / or time measurement result to the LMF.

[0177] Correspondingly, the LMF receives the carrier phase measurement result and / or time measurement result reported by the first device.

[0178] In a possible implementation, in a downlink positioning scenario, the UE and PRU may report measurement results to the LMF. For example, the UE and PRU may send a Provide Location Information message to the LMF, which carries the measurement results of the carrier phase and time.

[0179] In another possible implementation, in an uplink positioning scenario, each base station participating in positioning may report a measurement result to the LMF. For example, each base station participating in positioning sends a measurement response message (NRPPa measurement response) to the LMF, where the response message carries the measurement result.

[0180] 860. The LMF determines the location of the terminal device according to the measurement result of the carrier phase and / or the measurement result of time.

[0181] In one 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.

[0182] 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.

[0183] It should be understood that the term "and / or" in this document simply describes an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
