[0043] It should be understood that the general descriptions above and the detailed descriptions below are illustrative and explanatory and do not limit this disclosure. [Brief explanation of the drawing]

[0044] The drawings described herein are incorporated herein and constitute part of herein. Embodiments of the present disclosure are illustrated herein and are used together with herein to illustrate the principles of the present disclosure. [Figure 1] This is a schematic diagram of a wireless communication system as shown by one exemplary embodiment. [Figure 2] This is a flowchart of a positioning method shown by an exemplary embodiment. [Figure 3] This is a flowchart of a positioning method shown by an exemplary embodiment. [Figure 4] This is a block diagram of a positioning device shown by one exemplary embodiment. [Figure 5] This is a block diagram of a positioning device shown by one exemplary embodiment. [Figure 6] This is a block diagram of a positioning device shown by one exemplary embodiment. [Figure 7] This is a block diagram of a positioning device shown by one exemplary embodiment. [Modes for carrying out the invention]

[0045] Herein, exemplary embodiments are described in detail, with an example shown in the drawings. Where the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not necessarily limited to all embodiments consistent with this disclosure.

[0046] This disclosure provides a positioning method, which is applicable to the wireless communication system shown in Figure 1, where a terminal accesses the wireless access network via a network device such as a base station, and the network devices and core network devices of the wireless access network complete data replies and forward transfers to provide various communication services.

[0047] A wireless communication system is understood to be a network that provides wireless communication functionality. Wireless communication systems can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single-carrier frequency division multiple access (Single Carrier FDMA, SC-FDMA), and carrier sense multiple access with collision avoidance. Depending on factors such as network capacity, speed, and latency, networks can be divided into future-evolving networks such as 2G (English: generation) networks, 3G networks, 4G networks, or 5G networks, and 5G networks may also be called New Radio (NR) networks. For ease of explanation, this disclosure may refer to wireless communication networks as networks or systems. The network in this disclosure may include a Radio Access Network (RAN) and a Core Network (CN). The network may include network devices, such as radio network devices and core network devices. A radio network device may also be referred to as a base station. The network can provide network services to terminals via network devices, different carriers can provide different network services to terminals, and different carriers correspond to different carrier networks.For example, in 5G NR, a wireless network device, i.e., a wireless access network device, can be called a gNB. A gNB can also be embodied as at least one Transmission Reception Point (TRP). The core network device includes a network element with location management functionality. Optionally, the location management function network element includes a location server, which can be implemented as an LMF (Location Management Function), E-SMLC (Enhanced Serving Mobile Location Centre), SUPL (Secure User Plane Location), or SUPL SLP (SUPL Location Platform).

[0048] A terminal, sometimes called a mobile station (MS), user equipment (UE), or mobile terminal (MT), is a device that provides voice and / or data connectivity to a user. For example, a terminal may be a handheld device or an in-vehicle device with wireless connectivity. Currently, some examples of terminals include smartphones (mobile phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices. In the embodiments of this disclosure, the terminal will be referred to as a UE as an example.

[0049] 5G R16 introduces multiple positioning technologies, enabling device positioning by having a positioning measurement device measure a reference signal and report the positioning measurement results. In some of these positioning technologies, the positioning measurement device may be a terminal, which reports a positioning measurement report, and the core network device performs positioning based on this report. In other positioning technologies, the positioning measurement device may be a TRP, which reports a positioning measurement report, and the core network device performs positioning based on this report. When positioning is achieved through interaction between the terminal, TRP, and core network device, the transmission of the positioning reference signal is usually based on multi-path transmission. The positioning measurement results in the positioning measurement report reported to the terminal or TRP are usually unified measurement results corresponding to multi-path, and this positioning method affects positioning accuracy.

[0050] In the Rel-18 case study, the improvement of positioning accuracy using a carrier phase-based positioning method is being considered. Here, the information that needs to be measured and reported in the carrier phase-based positioning method includes the fractional part of the carrier phase and the total number of cycles. The fractional part of the carrier phase is the fractional part less than the total number of cycles, and is the measured value at time t. It can also be understood as the part of the phase difference between the reference signal generated at the receiving side and the carrier signal from the transmitting point that is less than one cycle. The total number of cycles is the total number of cycles of the carrier signal, calculated by accumulating each position counter from time t0 when the receiving side locked onto the satellite signal to measurement time t.

[0051] In view of this, embodiments of the present disclosure provide a positioning method, in which a carrier phase positioning measurement and reporting method based on at least one path is proposed, and in order to improve positioning accuracy, the carrier phase measurement and reporting method can indicate whether or not the at least one path is a direct path.

[0052] Here, a direct path can be understood as a path where the signal is not reflected, refracted, or diffracted by obstacles during transmission. Specifying a direct path can improve positioning accuracy.

[0053] In the embodiments of this disclosure, for the sake of ease of explanation, the instruction information that indicates information about a direct route is referred to as direct route instruction information.

[0054] Figure 2 is a flowchart of a positioning method shown by an exemplary embodiment, and as shown in Figure 2, the positioning method is applied to a positioning measurement device, which is a terminal or TRP, and includes the following steps.

[0055] In step S11, a positioning measurement report is reported, which includes at least one of the carrier phase measurement results and direct route instruction information.

[0056] In embodiments of this disclosure, the terminal or TRP may perform positioning measurements based on multiple paths, and the carrier phase measurement result may be a carrier phase measurement result determined when performing positioning measurements on different paths among the multiple paths, or a carrier phase measurement result determined when performing positioning measurements on all of the different paths among the multiple paths.

[0057] Here, the positioning measurement report may be based on a positioning reference signal and measured on different paths among several paths. This positioning reference signal may be, for example, a downlink positioning reference signaling (PRS), an uplink positioning reference signal such as a sounding reference signal (SRS), or any other newly introduced positioning reference signal.

[0058] Here, direct route indication information can be used to indicate whether or not at least one route being measured for positioning is information about a direct route.

[0059] Since the direct path measurement results can realistically represent the distance and direction between the TRP and the terminal, in the embodiments of this disclosure, positioning accuracy can be improved by including the carrier phase measurement results and / or direct path indication information in the reported positioning measurement report.

[0060] In one embodiment, the carrier phase measurement result includes at least one of the fractional part of the carrier phase and the total number of cycles of the carrier phase. For example, the carrier phase measurement result may include the total number of cycles of the carrier phase, or it may include the fractional part of the carrier phase, or it may include both the total number of cycles of the carrier phase and the fractional part of the carrier phase.

[0061] Here, the fractional part of the carrier phase and the total number of wavelengths of the carrier phase in the embodiments of this disclosure can be understood as the number of wavelengths obtained by measuring the positioning signal based on at least one path.

[0062] Embodiments of this disclosure enable a terminal or TRP to perform positioning measurements based on multiple paths. Here, the fractional part of the carrier phase included in the positioning measurement result includes the fractional part of the carrier phase corresponding to each of the different paths among the multiple paths, or the fractional part of the carrier phase corresponding to all of the multiple paths.

[0063] In embodiments of this disclosure, a terminal or TRP can perform positioning measurements based on multiple paths. Here, the total number of carrier phases included in the positioning measurement result includes the total number of carrier phases corresponding to each of the different paths among the multiple paths, or the total number of carrier phases corresponding to all of the multiple paths.

[0064] Furthermore, the positioning measurement results of the embodiments of this disclosure include direct route indication information. This direct route indication information is used to indicate whether or not a designated route is a direct route. On the other hand, the direct route indication information may include a bit (hereinafter referred to as the first bit) for indicating whether or not a designated route is a direct route. For example, one bit can be set for a given designated route, and the bit value can indicate whether or not this designated route is a direct route. For example, if the bit is 1, it indicates that the designated route is a direct route. If the bit is 0, it indicates that the designated route is not a direct route. On the other hand, the direct route indication information may include a bit (hereinafter referred to as the second bit) for indicating the probability that the designated route is a direct route. Here, the probability can take values ​​such as 0, 0.1, 0.2, ..., 0.9, 1, etc. For example, multiple bits can be set for a particular designated route to indicate the probability that that designated route is a direct route. For example, the number of bits can be set according to the number of possible values ​​for a probability value, and different probability values ​​can be associated with the possible values ​​of the bits. Furthermore, the bits can be used to indicate the probability that a specified path is a direct path.

[0065] In one embodiment, the direct path instruction information relating to the embodiment of the present disclosure may correspond to at least one of the following: a single (per) reference signal (RS), a single (per) transmission reception point (TRP), or a single (per) carrier phase measurement result.

[0066] Here, the RS corresponding to the direct route instruction information in the embodiments of this disclosure may be a positioning reference signal. This positioning reference signal may be, for example, a Positioning Reference Signaling (PRS), an uplink positioning reference signal such as an SRS, or any other newly introduced positioning reference signal.

[0067] Here, a single carrier phase measurement result includes a single carrier phase measurement result for multiple paths of one reference signal, or a single carrier phase measurement result for a first path of one reference signal, or a single carrier phase measurement result for a non-first path of one reference signal.

[0068] Here, if the direct path indication information corresponds to a single reference signal, the direct path indication information can be understood as whether or not a direct path exists in at least one path experienced by this reference signal, or the probability that a direct path exists. If the direct path indication information corresponds to a single TRP, the direct path indication information can be understood as whether or not a direct path exists in at least one path experienced by at least one reference signal corresponding to that TRP, or the probability that a direct path exists. The reference signal corresponding to this TRP includes a reference signal transmitted by the TRP or a reference signal transmitted by the terminal to the TRP. If the direct path indication information corresponds to a single carrier phase measurement result, and that carrier phase measurement result is a single measurement result of multiple paths of one reference signal, the direct path indication information can be understood as whether or not a direct path exists in at least one path experienced by that reference signal, or the probability that a direct path exists. If direct path indication information corresponds to a single carrier phase measurement result, and that carrier phase measurement result is the measurement result of the first or non-first path of the reference signal, then it can be understood that the direct path indication information is the probability that the first or non-first path experienced by that reference signal was a direct path or a direct path.

[0069] In addition, in the embodiments of this disclosure, the above positioning measurement report includes: The system includes at least one of the following: reference signal received power, arrival angle, departure angle, arrival time, arrival time difference, round-trip time value, indication information indicating whether the received time error (Rx time error group, REG) is the same, indication information indicating whether the transmitted time error (Tx time error group, TEG) is the same, and indication information indicating whether the transmitted and received time (Tx Rx time error group, TREG) errors are the same.

[0070] Here, the indication that REG is the same is used to indicate which reference signals use the same REG. The indication that TEG is the same is used to indicate which reference signals use the same TEG. The indication that TREG is the same is used to indicate which reference signals use the same TREG.

[0071] Furthermore, in the embodiments of this disclosure, the positioning measurement report can be reported from the terminal to a core network device such as a Location Management Function (LMF). The positioning measurement report can also be reported from the TRP to a core network device such as an LMF.

[0072] In the embodiments of this disclosure, the positioning accuracy is further improved by measuring and reporting the carrier phase positioning using the path, and by indicating whether or not it is a direct route.

[0073] Based on a similar line of thinking, embodiments of this disclosure further provide positioning methods performed by core network devices.

[0074] Figure 3 is a flowchart of a positioning method shown in an exemplary embodiment. As shown in Figure 3, the positioning method is applied to a core network device and includes the following steps.

[0075] In step S21, a positioning measurement report is received, and the positioning measurement report includes at least one of the carrier phase measurement result and direct route instruction information.

[0076] In the embodiments of this disclosure, the carrier phase measurement result may be the carrier phase measurement result determined when performing positioning measurements on different paths among multiple paths, or it may be the carrier phase measurement result determined when performing positioning measurements on all different paths among multiple paths.

[0077] Here, the positioning measurement report may be based on a positioning reference signal and may be measured on different routes among several routes. This positioning reference signal may be, for example, a PRS, an uplink positioning reference signal such as an SRS, or any other newly introduced positioning reference signal.

[0078] Here, direct route indication information can be used to indicate whether or not at least one route being measured for positioning is information about a direct route.

[0079] Since the direct path measurement results can realistically represent the distance and direction between the TRP and the terminal, in the embodiments of this disclosure, positioning accuracy can be improved by including the carrier phase measurement results and / or direct path indication information in the positioning measurement report.

[0080] In one embodiment, the carrier phase measurement result includes at least one of the fractional part of the carrier phase and the total number of cycles of the carrier phase. For example, the carrier phase measurement result may include the total number of cycles of the carrier phase, or it may include the fractional part of the carrier phase, or it may include both the total number of cycles of the carrier phase and the fractional part of the carrier phase.

[0081] Herein, in the embodiments of the present disclosure, the fractional part of the carrier phase and the total number of wavelengths of the carrier phase can be understood as the number of wavelengths obtained by measuring the positioning signal based on at least one path.

[0083] In the embodiments of this disclosure, the total number of carrier phases included in the positioning measurement result includes the total number of carrier phases corresponding to each of the different paths among the multiple paths, or the total number of carrier phases corresponding to all of the multiple paths.

[0084] In one embodiment, the direct route indication information may include a bit to indicate whether a specified route is a direct route. For example, one bit can be set for a given specified route, and the bit value can indicate whether this specified route is a direct route. For example, if the bit is 1, it indicates that the specified route is a direct route. If the bit is 0, it indicates that the specified route is not a direct route. On the other hand, the direct route indication information may include a second bit to indicate the probability that the specified route is a direct route. Here, the probability can take values ​​such as 0, 0.1, 0.2, ..., 0.9, 1, etc. For example, multiple bits can be set for a particular specified route to indicate the probability that that specified route is a direct route. For example, the number of bits can be set according to the number of possible values ​​for the probability value, and different probability values ​​can be associated with the possible values ​​of the bits, and the bit can further indicate the probability that the specified route is a direct route.

[0085] Here, each direct path instruction piece corresponds to at least one of a single reference signal, a single transmit / receive point, or a single carrier phase measurement result.

[0086] Here, the RS corresponding to the direct route instruction information related to the embodiments of this disclosure may be a positioning reference signal. This positioning reference signal may, for example, be a PRS for downlink positioning, an SRS or other reference signal for uplink positioning, or any other newly introduced positioning reference signal.

[0087] Here, a single carrier phase measurement result includes a single carrier phase measurement result for multiple paths of one reference signal, or a single carrier phase measurement result for a first path of one reference signal, or a single carrier phase measurement result for a non-first path of one reference signal.

[0088] Here, if the direct path indication information corresponds to a single reference signal, the direct path indication information can be understood as whether or not a direct path exists in at least one path experienced by this reference signal, or the probability that a direct path exists. If the direct path indication information corresponds to a single TRP, the direct path indication information can be understood as whether or not a direct path exists in at least one path experienced by at least one reference signal corresponding to that TRP, or the probability that a direct path exists. The reference signal corresponding to this TRP includes a reference signal transmitted by the TRP or a reference signal transmitted by the terminal to the TRP. If the direct path indication information corresponds to a single carrier phase measurement result, and that carrier phase measurement result is a single measurement result of multiple paths of one reference signal, the direct path indication information can be understood as whether or not a direct path exists in at least one path experienced by that reference signal, or the probability that a direct path exists. If direct path indication information corresponds to a single carrier phase measurement result, and that carrier phase measurement result is the measurement result of the first or non-first path of the reference signal, then it can be understood that the direct path indication information is the probability that the first or non-first path experienced by that reference signal was a direct path or a direct path.

[0089] In addition, in the embodiments of this disclosure, the above positioning measurement report includes: The system includes at least one of the following: reference signal received power, arrival angle, departure angle, arrival time, arrival time difference, round-trip time value, indicator information indicating whether REG is the same or not, indicator information indicating whether TEG is the same or not, and indicator information indicating whether TREG is the same or not.

[0090] Here, the indication that REG is the same is used to indicate which reference signals use the same REG. The indication that TEG is the same is used to indicate which reference signals use the same TEG. The indication that TREG is the same is used to indicate which reference signals use the same TREG.

[0091] In the embodiments of this disclosure, the positioning measurement report acquired by the core network device includes at least one of the carrier phase measurement results and direct route instruction information, thereby improving positioning accuracy.

[0092] The positioning method for core network devices applied in the embodiments of this disclosure is the same as the positioning method used by terminals or TRPs, and therefore will not be described here.

[0093] Furthermore, the positioning method provided by the embodiments of this disclosure can be applied to implementation processes in which a terminal, TRP, and core network device interactively achieve positioning. In the method in which a terminal, TRP, and core network device interactively achieve positioning, the terminal, TRP, and core network device each have the relevant functions in the above embodiments, so their description is omitted here.
