[0067] Figure 7 This is a block diagram illustrating a positioning device according to an exemplary embodiment. Detailed Implementation

[0068] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0069] This disclosure provides a positioning method that can be applied to... Figure 1 In the wireless communication system shown, such as Figure 1 As shown, the terminal accesses the wireless access network through wireless access network devices such as base stations. The wireless access network devices and the core network devices complete the backhaul and forward transmission of data to perform various communication services.

[0070] It is understood that a wireless communication system is 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 (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G, 3G, 4G, or future evolution networks, such as 5G networks, which can also be referred to as New Radio (NR). For ease of description, this disclosure sometimes refers to wireless communication networks simply as networks or systems. In this disclosure, networks may include radio access networks (RAN) and core networks (CN). A network includes network devices, such as wireless network devices and core network devices. Wireless network devices can also be called base stations. The network provides network services to terminals through these devices. Different operators can provide different network services to terminals; this can be understood as different operators having different network networks. For example, in 5G NR, wireless network devices, i.e., radio access network devices, can be called gNBs. A gNB can also be represented as at least one Transmission Reception Point (TRP). Core network devices include a location management function network element.Optionally, the location management function network element includes a location server, which can be implemented as any of the following: LMF (Location Management Function), E-SMLC (Enhanced Serving Mobile Location Centre), SUPL (Secure User Plane Location), or SUPL SLP (SUPL Location Platform).

[0071] 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 can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, 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 this embodiment, the terminal is referred to as a UE for illustrative purposes.

[0072] 5G R16 introduces various positioning technologies. These technologies use positioning measurement devices to measure reference signals and report the results, enabling device location. In some of these technologies, the positioning measurement device can be a terminal, which reports a positioning measurement report, and the core network equipment uses this report for positioning. In other technologies, the positioning measurement device can be a Telemetry Point (TRP), which reports a positioning measurement report, and the core network equipment uses this report for positioning. When positioning is achieved through interaction between the terminal, TRP, and core network equipment, the transmission of reference signals for positioning purposes is typically based on multipath transmission. The positioning measurement results reported by the terminal or TRP are usually a unified measurement result corresponding to the multipath path, which can affect positioning accuracy.

[0073] During the Rel-18 project initiation discussions, a carrier phase-based positioning method was being explored to improve positioning accuracy. This method requires measuring and reporting the fractional part and integer cycles of the carrier phase. The fractional part of the carrier phase refers to the portion less than a full cycle, representing the measurement value at time t. It can also be understood as the portion of the phase difference between the reference signal generated at the receiver and the carrier signal from the transmitting point that is less than one cycle. The integer cycle count is the number of integer cycles of the carrier signal accumulated by the position counter from the time the receiver locks onto the satellite signal at time t0 to the measurement time t.

[0074] In view of this, embodiments of the present disclosure provide a positioning method that proposes a carrier phase positioning measurement and reporting method based on at least one path, and can indicate whether the at least one path of the carrier phase measurement and reporting is a direct path, so as to improve positioning accuracy.

[0075] The direct path can be understood as the path of signal transmission without reflection, refraction, or diffraction from obstructions. Indicating the direct path can improve positioning accuracy.

[0076] For ease of description in this embodiment, the indication information that indicates information related to direct trajectory is referred to as direct trajectory indication information.

[0077] Figure 2 This is a flowchart illustrating a positioning method according to an exemplary embodiment, such as... Figure 2 As shown, the positioning method is used to locate a measuring device, which is a terminal or a TRP, and includes the following steps.

[0078] In step S11, a positioning measurement report is reported, which includes at least one of the following: carrier phase measurement results and direct path indication information.

[0079] In this embodiment of the disclosure, the terminal or TRP can perform positioning measurements based on multiple paths. The carrier phase measurement result can be the carrier phase measurement result determined when positioning measurements are performed separately for different paths among the multiple paths, or the carrier phase measurement result determined when positioning measurements are performed as a whole for different paths among the multiple paths.

[0080] The positioning measurement report can be based on positioning reference signals measured on different paths across multiple paths. These positioning reference signals can be, for example, downlink positioning reference signals (PRS), uplink positioning reference signals (SRS), or other newly introduced positioning reference signals.

[0081] Among them, the direct trajectory indication information can be used to indicate whether at least one trajectory measured in the positioning measurement is a direct trajectory.

[0082] Since the measurement results of the direct path can accurately reflect the distance and direction between the TRP and the terminal, in this embodiment of the disclosure, the positioning accuracy can be improved by including the carrier phase measurement results and / or direct path indication information in the reported positioning measurement report.

[0083] In one embodiment, the carrier phase measurement result includes at least one of the fractional part of the carrier phase and the integer number of carrier phase cycles. For example, the carrier phase measurement result may include the integer number of carrier phase cycles, or it may include the fractional part of the carrier phase, or it may include both the integer number of carrier phase cycles and the fractional part of the carrier phase.

[0084] In this embodiment, the fractional part of the carrier phase and the number of integer cycles of the carrier phase can be understood as the number of wavelengths obtained by measuring the positioning signal based on at least one path.

[0085] In this embodiment of the disclosure, the terminal or TRP can perform positioning measurements based on multiple paths. The fractional portion of the carrier phase included in the positioning measurement result includes the fractional portion of the carrier phase corresponding to each of the multiple paths, or the fractional portion of the carrier phase corresponding to the entire set of multiple paths.

[0086] In this embodiment of the disclosure, the terminal or TRP can perform positioning measurements based on multiple paths. The carrier phase integer cycles included in the positioning measurement results include the carrier phase integer cycles corresponding to each of the multiple paths, or the carrier phase integer cycles corresponding to the entire set of multiple paths.

[0087] Furthermore, the positioning measurement results in this embodiment include direct path indication information. This direct path indication information is used to indicate whether a specified path is a direct path. On one hand, the direct path indication information may include a bit (hereinafter referred to as the first bit) used to indicate whether the specified path is a direct path. In one example, for a specific specified path, 1 bit can be set to indicate whether the specified path is a direct path. For example, if the bit is set to 1, it indicates that the specified path is a direct path. If the bit is set to 0, it indicates that the specified path is not a direct path. On the other hand, the direct path indication information may include a bit (hereinafter referred to as the second bit) used to indicate the probability that the specified path is a direct path. The probability can be, for example, a value of 0, 0.1, 0.2, ..., 0.9, 1, etc. In one example, for a specific specified path, multiple bits can be set to indicate the probability that the specified path is a direct path. For example, the number of bits can be set according to the number of probability values, and the different probability values ​​correspond to different bit values, thereby indicating the probability that the specified path is a direct path.

[0088] In one embodiment, the direct path indication information involved in this disclosure may correspond to at least one of a single reference signal (RS), a single transmission reception point (TRP), or a single carrier phase measurement result.

[0089] In this embodiment of the disclosure, the RS corresponding to the direct trajectory indication information can be a positioning reference signal. This positioning reference signal can be, for example, a Positioning Reference Signaling (PRS), an uplink positioning reference signal such as an SRS, or other newly introduced positioning reference signals.

[0090] The single carrier phase measurement result includes the single carrier phase measurement result for multiple paths of a reference signal, or the single carrier phase measurement result for the first path of a reference signal, or the single carrier phase measurement result for a non-first path of a reference signal.

[0091] Specifically, when the direct path indication information corresponds to a single reference signal, it can be understood as whether a direct path exists or the probability of its existence among at least one path traversed by the reference signal. When the direct path indication information corresponds to a single TRP, it can be understood as whether a direct path exists or the probability of its existence among at least one path traversed by the at least one reference signal corresponding to the TRP. The reference signal corresponding to the TRP includes a reference signal transmitted by the TRP or a reference signal transmitted from the terminal to the TRP. When the direct path indication information corresponds to a single carrier phase measurement result, and this carrier phase measurement result is a single measurement result of multiple paths of a reference signal, the direct path indication information can be understood as whether a direct path exists or the probability of its existence among at least one path traversed by the reference signal. When the direct path indication information corresponds to a single carrier phase measurement result, and this carrier phase measurement result is a measurement result of the first path or a non-first path of a reference signal, the direct path indication information can be understood as whether the first path or a non-first path traversed by the reference signal is a direct path or the probability of it being a direct path.

[0092] It is understood that the positioning measurement report mentioned above in this embodiment of the disclosure also includes at least one of the following information:

[0093] Indication information for whether the reference signal received power, angle of arrival, departure angle, arrival time, arrival time difference, round-trip time, received time error (Rx time error group, REG) is the same, transmitted time error (Tx time error group, TEG) is the same, and transmitted and received time (Tx Rx time error group, TREG) errors are the same.

[0094] Specifically, the same REG indication information can be used to indicate which reference signals use the same REG. The same TEG indication information can be used to indicate which reference signals use the same TEG. The same TREG indication information can be used to indicate which reference signals use the same TREG.

[0095] Furthermore, in this embodiment of the present disclosure, the location measurement report mentioned above can be reported by the terminal to core network equipment such as the Location Management Function (LMF). Alternatively, the TRP can report the location measurement report to core network equipment such as the LMF.

[0096] In this embodiment of the disclosure, positioning accuracy is further improved by proposing a path-based carrier phase positioning measurement and reporting method, while indicating whether it is a direct trajectory.

[0097] Based on the same concept, embodiments of this disclosure also provide a positioning method performed by a core network device.

[0098] Figure 3 This is a flowchart illustrating a positioning method according to an exemplary embodiment, such as... Figure 3 As shown, the positioning method is used in core network equipment and includes the following steps.

[0099] In step S21, a positioning measurement report is received, which includes at least one of the following: carrier phase measurement results and direct path indication information.

[0100] In this embodiment of the disclosure, the carrier phase measurement result may be the carrier phase measurement result determined when positioning measurements are performed on different paths among multiple paths, or the carrier phase measurement result determined when positioning measurements are performed on different paths as a whole among multiple paths.

[0101] The positioning measurement report can be based on a positioning reference signal taken on different paths across multiple paths. This positioning reference signal can be, for example, a PRS (Positioning Reference Signal), an SRS (Short-Range Reference Signal), or other newly introduced positioning reference signals.

[0102] Among them, the direct trajectory indication information can be used to indicate whether at least one trajectory measured in the positioning measurement is a direct trajectory.

[0103] Since the measurement results of the direct path can accurately reflect the distance and direction between the TRP and the terminal, in this embodiment of the present disclosure, the positioning measurement report includes carrier phase measurement results and / or direct path indication information, which can improve positioning accuracy.

[0104] In one embodiment, the carrier phase measurement result includes at least one of the fractional part of the carrier phase and the integer number of carrier phase cycles. For example, the carrier phase measurement result may include the integer number of carrier phase cycles, or it may include the fractional part of the carrier phase, or it may include both the integer number of carrier phase cycles and the fractional part of the carrier phase.

[0105] In this embodiment, the fractional part of the carrier phase and the number of integer cycles of the carrier phase can be understood as the number of wavelengths obtained by measuring the positioning signal based on at least one path.

[0106] In this embodiment of the disclosure, 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 multiple paths, or includes the fractional part of the carrier phase corresponding to the entire set of multiple paths.

[0107] In this embodiment of the disclosure, the number of integer cycles of the carrier phase included in the positioning measurement result includes the number of integer cycles of the carrier phase corresponding to each of the multiple paths, or the number of integer cycles of the carrier phase corresponding to the entire set of multiple paths.

[0108] In one implementation, the direct path indication information may include, on the one hand, a first bit indicating whether a specified path is a direct path. In one example, for a given specified path, one bit may be set to indicate whether the specified path is a direct path. For example, a bit set to 1 indicates that the specified path is a direct path, and a bit set to 0 indicates that the specified path is not a direct path. On the other hand, the direct path indication information may include a second bit indicating the probability that the specified path is a direct path. The probability may be, for example, a value of 0, 0.1, 0.2, ..., 0.9, 1, etc. In one example, multiple bits may be set for a given specified path to indicate the probability that the specified path is a direct path. For example, the number of bits can be set according to the number of possible probability values, with each bit value corresponding to a different probability value, thus indicating the probability that the specified path is a direct path.

[0109] Each direct path indication corresponds to at least one of the following: a single reference signal, a single transmit / receive point, or a single carrier phase measurement result.

[0110] In this embodiment of the disclosure, the RS corresponding to the direct trajectory indication information can be a positioning reference signal. This positioning reference signal can be, for example, a PRS for downlink positioning, or a SRS for uplink positioning, or other newly introduced positioning reference signals.

[0111] The single carrier phase measurement result includes the single carrier phase measurement result for multiple paths of a reference signal, or the single carrier phase measurement result for the first path of a reference signal, or the single carrier phase measurement result for a non-first path of a reference signal.

[0112] Specifically, when the direct path indication information corresponds to a single reference signal, it can be understood as whether a direct path exists or the probability of its existence among at least one path traversed by the reference signal. When the direct path indication information corresponds to a single TRP, it can be understood as whether a direct path exists or the probability of its existence among at least one path traversed by the at least one reference signal corresponding to the TRP. The reference signal corresponding to the TRP includes a reference signal transmitted by the TRP or a reference signal transmitted from the terminal to the TRP. When the direct path indication information corresponds to a single carrier phase measurement result, and this carrier phase measurement result is a single measurement result of multiple paths of a reference signal, the direct path indication information can be understood as whether a direct path exists or the probability of its existence among at least one path traversed by the reference signal. When the direct path indication information corresponds to a single carrier phase measurement result, and this carrier phase measurement result is a measurement result of the first path or a non-first path of a reference signal, the direct path indication information can be understood as whether the first path or a non-first path traversed by the reference signal is a direct path or the probability of it being a direct path.

[0113] It is understood that the positioning measurement report mentioned above in this embodiment of the disclosure also includes at least one of the following information:

[0114] Reference signal received power, angle of arrival, departure angle, arrival time, time difference of arrival, round-trip time, indication information on whether REG is the same, indication information on whether TEG is the same, and indication information on whether TREG is the same.

[0115] Specifically, the indication information regarding whether REG and TEG are the same can be used to indicate which reference signals use the same REG. The indication information regarding whether TEG and TREG are the same can be used to indicate which reference signals use the same TREG.

[0116] In this embodiment of the disclosure, the positioning measurement report obtained by the core network device includes at least one of carrier phase measurement results and direct path indication information, which can improve positioning accuracy.

[0117] It is understood that the positioning method for core network devices provided in this disclosure is similar to the positioning method for terminals or TRPs, and the similarities will not be repeated here.

[0118] It is further understood that the positioning method provided in this disclosure can be applied to the implementation process of positioning through interaction between the terminal, TRP, and core network equipment. In the method of positioning through interaction between the terminal, TRP, and core network equipment, each of the terminal, TRP, and core network equipment possesses the relevant functions described in the above embodiments, which will not be repeated here.
