They do not constitute any limitation on the embodiments of this application.

[0120] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0121] This application provides a method, apparatus, and storage medium for reporting carrier phase measurements, so as to realize the acquisition and reporting of carrier phase measurements in A-IoT device positioning scenarios.

[0122] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0123] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G systems (5GS). These systems can use NTN technology to provide cellular coverage, but this application does not limit this.

[0124] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0125] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0126] With the booming development of IoT technology, the power supply, battery life and maintenance of IoT devices have become important reasons hindering the massive connection and ultra-large-scale development of IoT. Therefore, IoT technology needs to introduce devices without batteries or energy storage capabilities, or devices with energy storage capabilities but without the need for manual battery replacement or charging.

[0127] Among related technologies, low-complexity tag identification can be achieved through barcodes or radio frequency identification (RFID) technology. However, RFID technology suffers from severe interference and limited capacity in high-density deployment scenarios, which limits its application scenarios.

[0128] Based on this, a new type of Internet of Things (IoT) device has been introduced, namely the A-IoT device. An A-IoT device is a device without batteries or energy storage capacity, or a device with energy storage capacity that does not require manual replacement or charging. It can receive excitation electromagnetic signals emitted in the environment to obtain energy and operate under the drive of energy.

[0129] In scenarios such as factory, goods, archive, asset management, and warehouse storage, it is necessary to locate A-IoT devices to determine their position. Related technologies include positioning methods such as observed time difference of arrival (OTDOA), uplink observed time difference of arrival (UTDOA), downlink observed time difference of arrival (DL-TDOA), downlink time difference of arrival (UL-TDOA), and uplink time difference of arrival (UL-TDOA) for A-IoT device location. However, the positioning accuracy of these methods is relatively low.

[0130] Currently, carrier phase-based ranging and positioning technology can be used for device positioning, effectively improving positioning accuracy. During the positioning process, it is necessary to acquire corresponding carrier phase measurements. The main reason why carrier phase measurements can accurately determine the device's location is that the error in carrier phase measurements is generally only about 10% of the carrier wavelength. For example, when the carrier frequency is 2GHz, its carrier wavelength is 15 cm, and the error in carrier phase measurements is only 1-2 cm. Therefore, this application provides a solution for acquiring and reporting carrier phase measurements in IoT device positioning scenarios. The solution of this application embodiment will be described below with reference to the accompanying drawings.

[0131] First, combine Figure 1 and Figure 2 An applicable application scenario of the embodiments of this application will be introduced.

[0132] Figure 1This application provides an example of a suitable application scenario. Figure 1 ,like Figure 1 As shown, it includes a Location Management Function (LMF) network element 11, a first communication device 12, and an A-IoT device 13.

[0133] exist Figure 1 In the example, A-IoT device 13 is an IoT device to be located. A-IoT device 13 does not have the ability to generate signals independently and needs to receive external stimulus signals (such as...). Figure 1 The signal S1 in the middle is used to modulate the excitation signal to obtain the modulated signal (such as the signal S1 in the middle). Figure 1 The signal S2 in the signal is transmitted to the first communication device 12 by backscattering or reflection.

[0134] The first communication device 12 obtains the carrier phase measurement based on the modulated signal S2, and then reports the carrier phase measurement to the LMF network element 11.

[0135] exist Figure 1 In the example scenario, the first communication device 12 can be a terminal or a network device (such as...). Figure 1 In the network device A or terminal B), the first communication device 12 is the transmitting device of signal S1 and the receiving device of signal S2.

[0136] Figure 2 This application provides an example of a suitable application scenario. Figure 2 ,like Figure 2 As shown, it includes LMF network element 11, first communication device 12, A-IoT device 13, and second communication device 14.

[0137] exist Figure 2 In the example, A-IoT device 13 is an IoT device to be located. A-IoT device 13 does not have the ability to generate signals independently and needs to receive external stimulus signals (such as...). Figure 2 The signal S1 in the middle is used to modulate the excitation signal to obtain the modulated signal (such as the signal S1 in the middle). Figure 2 The signal S2 in the signal is transmitted to the first communication device 12 by backscattering or reflection.

[0138] The first communication device 12 obtains the carrier phase measurement based on the modulated signal S2, and then reports the carrier phase measurement to the LMF network element 11.

[0139] exist Figure 2 In the example scenario, the first communication device 12 can be a terminal or a network device (such as...). Figure 2 The first communication device 14 is the receiving device for signal S2, and the second communication device 14 can be a terminal or a network device (such as network device A or terminal B). Figure 2 Network device C or terminal D in the diagram is the device that transmits signal S1.

[0140] In the above embodiments, combined with Figure 1 and Figure 2 An applicable application scenario of this application embodiment is described. In some scenarios, configuration information (e.g., excitation signal configuration information) needs to be transmitted between LMF network element 11 and the first communication device 12, and between LMF network element 11 and the second communication device 14. Taking the transmission of configuration information between LMF network element 11 and the first communication device 12 as an example, LMF network element 11 can directly send configuration information to the first communication device 12, or it can send configuration information to the first communication device 12 through other network devices.

[0141] In the scenario where LMF network element 11 directly sends configuration information to the first communication device 12, if the first communication device 12 is a network device, the LMF network element 11 and the first communication device 12 can transmit configuration information via NR Positioning Protocol A (NRPPa); if the first communication device 12 is a terminal, the LMF network element 11 and the first communication device 12 can transmit configuration information via LTE Positioning Protocol (LPP). Other dedicated protocols can also be used for configuration information transmission between the LMF network element 11 and the first communication device 12, and this embodiment does not limit the specific protocols used in this application.

[0142] In the scenario where LMF network element 11 sends configuration information to the first communication device 12 through other network devices, if the first communication device 12 is a network device, after LMF network element 11 sends configuration information to other network devices, the other network devices and the first communication device 12 transmit configuration information through the X2 interface; if the first communication device 12 is a terminal, after LMF network element 11 sends configuration information to other network devices, the other network devices can carry the configuration information through Radio Resource Control (RRC) signaling, thereby sending the configuration information to the first communication device 12.

[0143] The implementation scheme for transmitting configuration information between LMF network element 11 and the second communication device 14 is similar to the implementation scheme for transmitting configuration information between LMF network element 11 and the first communication device 12, and will not be described in detail here.

[0144] Below Figure 1 and Figure 2 In the example application scenario, combined with Figure 3 The solutions of the embodiments of this application will be described.

[0145] Figure 3 This is a flowchart of a carrier phase measurement reporting method provided in an embodiment of this application. The method is applied to a first communication device, such as... Figure 3 As shown, the method includes:

[0146] S31, acquire the first signal, which is the signal obtained by the IoT device modulating the excitation signal.

[0147] Since IoT devices lack the ability to generate signals independently, in scenarios requiring location tracking of IoT devices, an excitation signal can be sent to the IoT device via a first or second communication device. For example, the IoT device can... Figure 1 and Figure 2 Example A-IoT device 13.

[0148] After receiving an excitation signal, an IoT device can modulate it. The modulation method can be one of frequency modulation (FM), amplitude modulation (AM), or phase modulation (PM). By modulating the excitation signal, the information to be transmitted can be mapped onto a generated first signal, which is then sent to a first communication device. The first communication device is a communication device within the signal coverage area of ​​the IoT device. The process of the IoT device sending the first signal to the first communication device can be done through reflection or backscattering. Correspondingly, the first communication device receives the first signal.

[0149] S32, based on the first signal, determine the carrier phase measurement quantity corresponding to the excitation signal.

[0150] The carrier phase measurement refers to the phase of the channel response signal of the first signal after modulation by the IoT device, that is, the phase difference of the first signal from the IoT device to the first communication device. After acquiring the first signal, the first communication device can perform down-conversion processing on the first signal, converting it from a radio frequency signal into a baseband signal (that is, the channel response signal of the first signal), and then determine the phase value of the channel response signal as the carrier phase measurement corresponding to the excitation signal.

[0151] S33, send carrier phase measurement to the first functional network element. The carrier phase measurement is used to locate IoT devices.

[0152] After obtaining the carrier phase measurement, the first communication device can send the carrier phase measurement to the first functional network element. The carrier phase measurement and the integer ambiguity corresponding to the carrier phase measurement are used to determine the location of the Internet of Things device.

[0153] The meanings of integer ambiguity and first carrier phase measurement can be combined Figure 4 To understand. Figure 4 A schematic diagram illustrating ranging based on integer ambiguity and carrier phase measurements provided for embodiments of this application, as shown below. Figure 4 As shown, let the distance between point M (the location of the IoT device) and point N (the location of the first communication device) be d. When measuring the distance between points M and N, a first signal can be backscattered or reflected from point M to the first communication device at point N by the IoT device. The wavelength of this first signal is λ. Then:

[0154] d=(x+φ)*λ (1)

[0155] Where φ is the phase difference of the first signal from point M to point N, i.e., the carrier phase measurement, and x is the integer ambiguity corresponding to the carrier phase measurement. Where x is a positive integer, and φ is a decimal between 0 and 1 (if expressed in degrees, φ is an angle value between 0 and 2π).

[0156] by Figure 4 For example, the distance d = 100.3λ, where x = 100 represents the integer ambiguity and φ = 0.3 represents the carrier phase measurement. Therefore, the distance between the first communication device and the IoT device can be obtained by measuring the integer ambiguity and the carrier phase measurement, combined with the wavelength of the first signal.

[0157] Then, based on the distance between the first communication device and the IoT device, the IoT device can be located. For example, the first signal can be backscattered or reflected by the IoT device to multiple first communication devices to obtain the carrier phase measurement corresponding to multiple first communication devices. Then, the distance between each of the multiple first communication devices and the IoT device can be obtained by combining equation (1). Based on the distance between each of the multiple first communication devices and the IoT device, and the location of each of the multiple first communication devices, the location of the IoT device can be determined.

[0158] The carrier phase measurement reporting method provided in this application involves a first communication device acquiring a first signal, which is a signal obtained by an IoT device modulating an excitation signal. The first communication device then determines the carrier phase measurement corresponding to the excitation signal based on the first signal and sends the carrier phase measurement to a first functional network element. The carrier phase measurement is used for locating the IoT device. In the scenario of IoT device location, since the IoT device does not have the ability to independently generate signals, it receives and modulates the excitation signal, and then transmits the first signal through backscattering or reflection. This allows the first communication device to obtain and report the carrier phase measurement based on the first signal.

[0159] Based on any of the above embodiments, the solutions of the embodiments of this application will be further described below with reference to the accompanying drawings.

[0160] against Figure 1 In the example scenario (i.e., both the device sending the excitation signal to the IoT device and the device receiving the first signal backscattered or reflected by the IoT device are the first communication devices), the following will be combined with...

[0162] S501, the first communication device sends a location request to the first functional network element.

[0163] When an IoT device has a location requirement, the first communication device sends a location request to the first functional network element. The location request is used to request the location of the IoT device, and the first functional network element receives the location request accordingly.

[0164] S502, the first functional network element sends excitation signal configuration information to the first communication device.

[0165] Upon receiving a location request, the first functional network element can determine that the IoT device needs to be located. Since IoT devices do not have the ability to generate signals independently and require backscattering or reflection of excitation signals, the first functional network element can configure or generate excitation signal configuration information, which is used to indicate the excitation signal.

[0166] Excitation signals are reference signals used for IoT device positioning. For example, they can include downlink time difference of arrival (DL-TDOA) or uplink time difference of arrival (UL-TDOA) positioning reference signals, such as positioning reference signals (PRS), channel state indication reference signals (CSI-RS), sounding reference signals (SRS), etc. Any reference signal that can be used for IoT device positioning can be used as an excitation signal.

[0167] Optionally, the excitation signal configuration information can be used to indicate one or more of the following information: amplitude, phase, frequency, wavelength, etc. of the excitation signal.

[0168] Taking a single-carrier excitation signal as an example, the excitation signal can be expressed in the form of the following equation (2):

[0169]

[0170] Where s(t) is the excitation signal, t is time, and A in f is the amplitude of the excitation signal. c φ is the frequency (i.e., the frequency point) of the excitation signal. in This represents the initial phase deviation of the excitation signal.

[0172] S503, the first functional network element sends reference signal sequence configuration information to the first communication device and / or IoT device, the reference signal sequence configuration information being used to indicate the reference signal sequence.

[0173] The reference signal sequence is a signal sequence used to modulate the excitation signal. For example, it can be a sequence of 1s and 0s, such as {1,0,1,0,1,0}, {1,1,1,0,1,0,1,0}, etc. Reference signal sequence configuration information indicates the reference signal sequence. Based on this configuration information, the reference signal sequence can be determined, and it is used to modulate the excitation signal.

[0174] Optionally, if the reference signal sequence is pre-configured, both the first communication device and the IoT device can know the reference signal sequence in advance. In this case, the first functional network element does not need to send the reference signal sequence configuration information to the first communication device and the IoT device.

[0175] Optionally, the reference signal sequence is configured by a first functional network element, in which case the first functional network element sends the reference signal sequence configuration information to a first communication device and / or an Internet of Things device.

[0176] S504, the first communication device sends an excitation signal to the Internet of Things device.

Correspondingly, the IoT device receives the excitation signal.

[0178] S505, the IoT device modulates the excitation signal based on the reference signal sequence to obtain the first signal.

[0179] The IoT device can modulate the excitation signal using any of the following methods: amplitude modulation, frequency modulation, or phase modulation. The IoT device determines the modulation method of the excitation signal and modulates the excitation signal based on the modulation method and a reference signal sequence to obtain the first signal.

[0180] Optionally, the IoT device can select one of amplitude modulation, frequency modulation, or phase modulation as the excitation signal.

[0181] Optionally, the first functional network element sends modulation mode indication information to the IoT device. The modulation mode indication information is used to indicate the modulation mode of the excitation signal. Correspondingly, the IoT device receives the modulation mode indication information and determines the modulation mode of the excitation signal based on the modulation mode indication information.

[0182] The following describes the process by which an IoT device modulates an excitation signal using different modulation methods to obtain a first signal. In the following embodiments, taking the excitation signal s(t) as an example of equation (2), the first communication device sends the excitation signal s(t) to the IoT device, and the excitation signal received by the IoT device is y. in (t), y in (t) can be expressed in the form of the following equation (3):

[0190] It should be noted that A out-off This indicates that IoT devices do not perform backscattering / reflection. For transceiver integrated scenarios, A out-off At that time, there is no signal at the first communication device. For example, if the reference signal sequence is {1,0,1,0,1,0}, then the corresponding amplitude value of the first signal is {A}. out-on ,0,A out-on ,0,A out-on In other words, for a 1 in the reference signal sequence, the amplitude of the first signal obtained by amplitude modulation of the excitation signal based on the reference signal sequence is A. out-on For the 0 in the reference signal sequence, the amplitude of the first signal obtained by amplitude modulation of the excitation signal based on the reference signal sequence is 0.

[0191] The following describes the implementation scheme when the modulation method is frequency modulation.

[0195] It should be noted that f out-off This indicates that IoT devices do not perform backscattering / reflection. For transceiver integrated scenarios, f out-off At that time, there was no signal at the first communication device.

[0196] The following describes the implementation scheme when the modulation method is phase modulation.

[0197] If the reference signal sequence is {1,0,1,0,1,0}, and taking phase modulation as an example, then for y in (t) Phase modulation can obtain the first signal y. out (t) is:

[0198]

[0199] Where h1 is the attenuation caused by the channel between the IoT device and the first communication device, t is time, and A in f is the amplitude of the excitation signal. c φ is the frequency of the excitation signal. in Let τ1 be the initial phase deviation of the excitation signal, τ1 be the time delay of the excitation signal from the transmitting antenna of the first communication device to the receiving antenna of the IoT device via wireless transmission, w1 be the complex Gaussian received noise of the IoT device, and φ be the initial phase deviation of the excitation signal. out-on For IoT devices, the reference signal sequence is modulated and mapped to the phase value of the first signal, φ. scatter This could be a phase shift caused by reflection or a non-ideal phase caused by the transmitting circuit in an IoT device.

[0227] Where, φ w The phase of w2.

[0228] If the IoT device modulates the excitation signal using phase modulation, based on the above equation (6), the first signal r(t) received by the first communication device can be determined as:

[0229]

[0230] Where h1 is the attenuation caused by the channel between the IoT device and the first communication device, t is time, and A in f is the amplitude of the excitation signal. c φ is the frequency of the excitation signal. in Let τ1 be the initial phase deviation of the excitation signal, τ1 be the time delay of the excitation signal from the transmitting antenna of the first communication device to the receiving antenna of the IoT device via wireless transmission, w1 be the complex Gaussian received noise of the IoT device, and φ be the initial phase deviation of the excitation signal. out-on For IoT devices, the reference signal sequence is modulated and mapped to the phase value of the first signal, φ. scatter w1 represents the phase abrupt change caused by reflection or the non-ideal phase caused by the transmitting circuit in the IoT device, and w2 represents the sum of the received thermal noise of the first communication device and w1.

[0248] 1.2 Location indication information, used to indicate the location of the first communication device and / or the location of the second communication device.

[0249] Location indication information includes at least one of the following (a)-(d):

[0250] (a) Identification of the first communication device.

[0251] The identifier of a communication device can have a mapping relationship with its location; for example, different identifiers correspond to different locations or areas. The first functional network element can store the mapping relationship between the identifier of the communication device and its location. If the location indication information includes the identifier of the first communication device, the first functional network element determines the location of the first communication device based on the mapping relationship between the identifier of the communication device and its location, as well as the identifier of the first communication device itself.

[0252] (b) Location information of the first communication device.

[0253] The location information of the first communication device may include, for example, the area identifier where the first communication device is located, the latitude and longitude of the first communication device, etc. If the location indication information includes the location information of the first communication device, the first functional network element can determine the location of the first communication device based on the location information of the first communication device.

[0254] (c) Identification of the second communication device.

[0255] The identifier of a communication device can have a mapping relationship with its location; for example, different identifiers correspond to different locations or areas. The first functional network element can store the mapping relationship between the identifier of the communication device and its location. If the location indication information includes the identifier of a second communication device, the first functional network element determines the location of the second communication device based on the mapping relationship between the identifier of the communication device and its location, as well as the identifier of the second communication device.

[0256] (d) Location information of the second communication device.

[0257] The location information of the second communication device may include, for example, the area identifier where the second communication device is located, the latitude and longitude of the second communication device, etc. If the location indication information includes the location information of the second communication device, the first functional network element can determine the location of the second communication device based on the location information of the second communication device.

In this case, the location indication information may include the identifier of the first communication device and / or the location information of the first communication device.

[0259] Optionally, if the device sending the excitation signal to the IoT device is a second communication device, and the device receiving the first signal is a first communication device, then the location indication information is used to indicate the location of the first communication device and / or the location of the second communication device. In this case, the location indication information may include information for indicating the location of the first communication device, and / or information for indicating the location of the second communication device. Specifically, the information for indicating the location of the first communication device may include the identifier of the first communication device and / or the location information of the first communication device, and the information for indicating the location of the second communication device may include the identifier of the second communication device and / or the location information of the second communication device.

[0260] 1.3 Measurement parameter information, used to indicate the measurement parameters of the first signal.

[0261] The measurement parameter information includes at least one of the following (e)-(h):

[0262] (e) Angle measurement information, used to indicate the angle of arrival of the first signal at the first communication device.

[0263] If the first communication device has a multi-antenna array, when the first communication device receives the first signal, it can obtain the angle of arrival of the first signal from the IoT device to the first communication device and report it to the first functional network element. The first functional network element combines the angle of arrival and carrier phase measurement to locate the IoT device.

[0264] (f) Time information, used to indicate the time difference between the first moment and the second moment.

[0265] The first moment refers to the moment when either the first or second communication device sends the excitation signal. If both the device sending the excitation signal to the IoT device and the device receiving the first signal are the first communication device, then the first moment is the moment when the first communication device sends the excitation signal; if the device sending the excitation signal to the IoT device is the second communication device, and the device receiving the first signal is the first communication device, then the first moment is the moment when the second communication device sends the excitation signal. Figure 5 In the example scheme, the first moment is the moment when the first communication device sends an excitation signal to the IoT device. The second moment is the moment when the first communication device receives the first signal.

[0266] (g) Receive power information, used to indicate the received power of the first signal.

[0267] Received power information may include, for example, Reference Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Signal-to-noise ratio (SNR), Signal-to-Interference-plus-Noise Ratio (SINR), and so on.

[0268] Since multiple communication devices may exist within the signal coverage area of ​​an IoT device, and all of these devices can receive the first signal, the first functional network element can identify the communication device with the higher received power of the first signal based on the received power information of each communication device. Because the first communication device has a higher received power, it indicates that the interference received by the first signal is likely to be less, which is more helpful for locating the IoT device.

[0269] (h) Speed ​​information, used to indicate the transmission speed of the first signal.

[0270] The first communication device can also acquire the transmission speed of the first signal and report the speed information to the first functional network element. The first functional network element can determine the transmission speed of the first signal based on the speed information.

[0271] In summary, the solution of this application embodiment addresses a scenario where both the transceiver and the device receiving the first signal are integrated (i.e., both the device sending the excitation signal to the IoT device and the device receiving the first signal are first communication devices). The IoT device receives the excitation signal sent by the first communication device, modulates the excitation signal, and backscatters or reflects the first signal back to the first communication device. The first communication device then obtains a carrier phase measurement based on the first signal and reports it to the first functional network element, enabling the first functional network element to locate the IoT device based on the carrier phase measurement. Furthermore, the first communication device can also report one or more of the following information: positioning mode indication information, location indication information, and measurement parameter information, enabling the first functional network element to locate the IoT device based on the carrier phase measurement and this information.

[0272] In the above embodiments, the implementation scheme is introduced in the scenario where both the device sending the excitation signal to the IoT device and the device receiving the first signal are first communication devices. The following will introduce the implementation scheme in the scenario where the device sending the excitation signal to the IoT device is a second communication device and the device receiving the first signal is a first communication device.
