[0053] It should be noted that Figure 1An example is shown of a network side device, two terminals and two A-IoT devices. Optionally, the wireless communication system may include at least two network side devices and the coverage range of each network side device may include other numbers of terminals and A-IoT devices. This embodiment of the present application is not limited to this.
[0054] To facilitate a better understanding of the embodiments of the present application, the Ambient Internet of Things (A-IoT) is described.
[0055] A-IoT devices have ultra-low complexity and ultra-low power consumption.
[0056] A-IoT, also known as ambient power-enabled Internet of Things (Ambient Power-Enabled IoT), is a type of Internet of Things (IoT) service. A-IoT devices are powered by energy harvesting. A-IoT devices lack batteries or have limited energy storage capabilities (for example, using a capacitor). Energy harvesting can be done from radio waves, light, motion, heat, or other suitable energy sources.
[0057] A-IoT devices can also be A-IoT terminals, passive IoT devices, ambient power (AMP) devices, zero-power devices, low-power IoT devices, IoT devices, transponders, tags, and radio frequency identification (RFID) tags. These devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to this low overall power consumption, communication energy can come from the environment, such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals.
[0058] A-IoT devices can be classified based on energy source, energy storage capability, and passive or active emission. Specifically, they can include the following three types of devices:
[0059] Device Type A: A passive device with no independent signal generation or amplification, i.e., backscatter transmission.
[0060] Device Type B: A semi-passive device, also within the passive device category, with energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of reflected signals.
[0061] Device Type C: Active device, with energy storage and independent signal generation, that is, active RF components for transmission.
[0062] To facilitate a better understanding of the embodiments of the present application, backscatter communication (BSC) is described.
[0063] Backscatter communication refers to the use of radio frequency signals from other devices or the environment to modulate the signal and transmit its own information. Backscatter technology, a passive or low-energy technology, is characterized by its ability to transmit its own signal by modifying the characteristics of the received ambient radio frequency signal, such as its phase or amplitude, achieving extremely low or zero power consumption.
[0064] For example, a backscatter transmission method based on binary on-off keying (OOK) can be as follows: Figure 2 As shown, a simple implementation method is that when the tag needs to send '1', the tag reflects the incident carrier signal, and when the tag needs to send '0', it does not reflect.
[0065] For example, backscatter communication can be as follows: Figure 3 As shown, the A-IoT device receives the wireless signal sent by the reading and writing device, modulates the wireless signal, loads the information to be sent, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication.
[0066] Backscatter communication devices (such as A-IoT) control the circuit's reflection coefficient Γ by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The signal reflection coefficient can be expressed as:
[0067]
[0068] Where Z0 is the antenna characteristic impedance and Z1 is the load impedance. Assume that the incident signal is S in (t), the output signal is Therefore, corresponding amplitude modulation, frequency modulation or phase modulation can be achieved by reasonably controlling the reflection coefficient.
[0069] Backscatter communication devices (such as A-IoT devices) typically use low-power reception, typically using low-power RF, IF, or baseband envelope detection. The waveform of the transmitted signal typically uses simple modulation methods such as on-off keying (OOK), amplitude shift keying (ASK), and frequency shift keying (FSK).
[0070] The device that communicates with such low-power devices (such as A-IoT devices) is called a read-write device or a first network element. For example, it can be a terminal or a relay device or a repeater, or a base station or TRP, or a device with read-write functions, such as a reader / writer. The specific details are not limited here.
[0071] To facilitate a better understanding of the embodiments of the present application, the A-IoT data / service types are explained.
[0072] Device-originating (DO) and device-terminating (DT) data indicate that the data flow originates from or is transmitted to an A-IoT device (similar to an RFID tag). Data flows originating from A-IoT devices, or DO data, can be further categorized as device-originating-autonomous (DO-A) and device-originating–device-terminated triggered (DO-DTT).
[0073] DO-A, which means devices autonomously initiate data transmission, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary.
[0074] DO-DTT refers to devices initiating data transmission after being triggered by the network. For example, asset identification, status reporting, and tracking are all downlink-triggered reports. Readers collect data from tags by triggering inventory processes. Because the data is generated / initiated in IoT devices, this service should be considered a DO service initiated by a tag, triggered by a command sent by the reader.
[0075] To facilitate a better understanding of the embodiments of the present application, the information transmission between the reader and the tag in the RFID is described.
[0076] RFID is a traditional backscatter communication system whose primary design goal is to identify and read data from BSC devices (i.e., tags) within the reader's coverage area. Because RFID was initially used for automated inventory counting of large quantities of goods, the process of identifying and reading tags is also known as inventorying. For example, after the reader sends a query command (Query), the tag responds (Reply). For example, if the Reply is RN16, the tag generates a 16-bit random number and sends it to the reader. The reader then sends this sequence to the tag via an ACK command. After the tag successfully verifies the RN16 in the ACK, it sends the subsequent data (such as PC / XPC, EPC, etc.) to the reader.
[0077] like Figure 4 As shown, the command (Command) of the reader (Reader) operation can be shown in the following Table 1, and the status of the tag (Tag) can be shown in the following Table 2.

[0079]
[0080]
[0081] Table 2
[0082]
[0083] To facilitate a better understanding of the embodiments of the present application, NR positioning is explained.
[0084] The terminal's location can be supported by radio access technology (RAT)-dependent positioning methods, such as measurements of RAT signals from the access network by the target terminal or measurements of RAT signals from the access network by the target terminal. The terminal's location can also be supported by RAT-independent positioning methods, such as non-RAT measurements or other information to determine the terminal's location.
[0085] Taking NR as an example, in the Mobile Terminated Location Request (MT-LR) positioning, the Location Services (LCS) client initiates a location request to the 5GC Gateway Mobile Location Center (GMLC), and the GMLC initiates a service request to provide positioning information to the AMF. The AMF checks the UE status based on the UE's Subscription Permanent Identifier (SUPI). When the UE is in the Connection Management (CM) Idle (IDLE), it initiates a network-triggered service request, so that the UE establishes a Non-Access Stratum (NAS) signaling connection with the AMF. After that, the AMF initiates a request for the UE's current location to the LMF, which interacts with the UE through the LTE Positioning Protocol (LPP) message, or interacts with the UE's serving Next Generation Radio Access Network (NG-RAN) node (gNB or NG-eNB) through the NR Positioning Service a (NRPPa) message. After obtaining the UE location, LMF provides the UE location information to AMF, AMF then provides it to GMLC, and finally GMLC provides the UE location to the LCS client.
[0086] In NR positioning, the network needs to send a positioning reference signal (PRS) and the terminal sends a channel sounding reference signal (SRS).
[0087] To facilitate a better understanding of the embodiments of the present application, GNSS positioning is explained.
[0088] The UE receives satellite signals through the GNSS module for positioning. For example, the UE receives signals from multiple satellites on or near the Earth's surface and calculates the UE's position.
[0089] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0090] Figure 4 is a schematic flow chart of a positioning method 200 according to an embodiment of the present application, such as Figure 4 As shown, the positioning method 200 may include at least part of the following contents:
[0091] S210: The terminal obtains A-IoT information; wherein the A-IoT information includes at least one of the following: identification information of at least one A-IoT device, location information of at least one A-IoT device, grid information of at least one A-IoT device, and reflected signal strength information of at least one A-IoT device;
[0092] S220: The terminal determines the location information of the terminal according to the A-IoT information.
[0093] It should be understood that Figure 4 The steps or operations of the positioning method 200 are shown, but these steps or operations are only examples, and the present application may also perform other operations or Figure 4 Variations of the various operations in .
[0094] In an embodiment of the present application, the terminal obtains A-IoT information, and the terminal determines its location information based on the A-IoT information, that is, the terminal can be positioned with the assistance of the A-IoT device. The A-IoT device has the advantages of low cost, low power consumption, low complexity, and maintenance-free, thereby reducing the power consumption of terminal positioning and improving network energy-saving performance.
[0095] In the embodiment of the present application, the grid can also be understood as a network zone.
[0096] In some embodiments, the cells in the network may be divided into at least two grids. For example, a schematic diagram of dividing the cells in the network into grids may be as follows: Figure 5 shown.
[0097] In some embodiments, the network side may support at least one mesh segmentation scheme or granularity, for example, mesh segmentation according to the granularity of A-IoT devices.
[0098] For example, different cells in the network may use a unified grid segmentation scheme or granularity, and an A-IoT device may be located in at least two cells at the same time.
[0099] For example, an operator can deploy A-IoT devices in the network, and the cells in the network are divided into multiple grids. The terminal or A-IoT device can be in a specific grid, that is, the location information of the terminal or A-IoT device can be represented by the grid information.
[0100] In some embodiments, the A-IoT device may also be an A-IoT terminal, a passive Internet of Things (Passive-IoT) device, an ambient energy (AMP) device, a zero-power device, a low-power IoT device, an IoT device, a response device, a tag, an RFID tag, etc.
[0101] In some embodiments, the terminal obtains A-IoT information through an A-IoT device.
[0102] In some embodiments, the above S210 may specifically include:
[0103] The terminal obtains A-IoT information through at least one of the following:
[0104] Inventory, detection, and measurement of A-IoT devices.
[0105] It should be noted that, from the perspective of the terminal (UE), the UE has A-IoT capability (capable), which is called AmbientIoT capable UE, that is, the UE has 3GPP communication capability and Ambient IoT capability. Ambient IoT capable UE can take inventory of Ambient IoT devices. For example, the UE can take inventory of Ambient IoT devices under the control of the network, for example, the network configures wireless resources for the UE so that the UE performs Ambient IoT related operations on the wireless resources. In an embodiment of the present application, the terminal (UE) can take inventory or detect or measure these A-IoT devices. These operations of taking inventory or detecting or measuring A-IoT devices can be regarded as a background task in the 3GPP communication process.
[0106] For example, the terminal (UE) can inventory, detect, or measure these A-IoT devices to obtain UE location information. That is, with the assistance of A-IoT devices, the UE's location in the network can be determined.
[0107] In some embodiments, the location information of the terminal includes but is not limited to at least one of the following:
[0108] The identifiers of A-IoT devices detected by the terminal, the identifiers of the A-IoT devices closest to the terminal, the identifiers of the A-IoT devices with the strongest reflected signal strength detected by the terminal, the identifiers of A-IoT devices whose reflected signal strength exceeds the reflected signal strength threshold detected by the terminal, the identifiers of A-IoT devices detected by the terminal within a specific range centered on the terminal, information about the grid in which the terminal is located, the absolute position of the terminal, the relative position of the terminal, and a proximity indicator.
[0109] The proximity indication is used to indicate that the terminal is approaching or leaving at least one specific A-IoT device.
[0110] Exemplarily, the location information of the terminal includes an identifier of an A-IoT device detected by the terminal. Since the location of an A-IoT device is fixed, the location of the terminal can be represented by the identifier of the detected A-IoT device.
[0111] In this embodiment, by determining the grid position of the terminal in the network cell, the location information of the terminal can potentially be further utilized to improve communication performance.
[0112] Optionally, a specific A-IoT device may be configured by the network side, or a specific A-IoT device may be agreed upon by a protocol.
[0113] Optionally, the specific range may be agreed upon by a protocol, or the specific range may be configured by the network side, or the specific range may be determined by negotiation between the terminal and the network side device.
[0114] In some embodiments, the grid in which the terminal is located includes but is not limited to at least one of the following:
[0115] The grid where the A-IoT device closest to the terminal is located, as detected by the terminal;
[0116] The grid where the A-IoT device with the strongest reflected signal detected by the terminal is located;
[0117] The grid where the A-IoT device whose reflected signal strength detected by the terminal exceeds the reflected signal strength threshold is located;
[0118] The intersection of the grids where at least two A-IoT devices are located detected by the terminal;
[0119] The grid that appears most frequently among the grids where at least two A-IoT devices are located detected by the terminal;
[0120] The grid with the highest probability of appearing among the grids where at least two A-IoT devices detected by the terminal are located.
[0121] In some implementations, a terminal can determine its grid location based on the grid location of the A-IoT device. For example, if the terminal detects that the closest A-IoT device is located in grid A, the terminal can determine that it is in grid A. For another example, if the terminal detects that the A-IoT device with the highest reflected signal strength is located in grid A, the terminal can determine that it is in grid A. For another example, if the terminal detects that the A-IoT device with reflected signal strength exceeding a reflected signal strength threshold is located in grid A, the terminal can determine that it is in grid A.
[0122] Exemplarily, the grid information where the terminal is located includes the intersection of grids where at least two A-IoT devices detected by the terminal are located. For example, in the A-IoT information, A-IoT device A is in grid 1 of cell 1, A-IoT device B is in grid 1 of cell 1 and grid 2 of cell 2, and A-IoT device C is in grid 1 of cell 1 and grid 2 of cell 2. Then the grid where the terminal is located is grid 1 of cell 1.
[0123] Exemplarily, the grid in which the terminal is located includes the grid that appears most frequently among the grids in which at least two A-IoT devices are located detected by the terminal, or the grid with the highest probability of appearing among the grids in which at least two A-IoT devices are located detected by the terminal. In the A-IoT information, A-IoT device A is in grid 1 of cell 1, A-IoT device B is in grid 1 of cell 1 and grid 2 of cell 2, and A-IoT device C is in grid 3 of cell 1 and grid 3 of cell 2. Then the grid in which the terminal is located is grid 1 of cell 1.
[0124] In some embodiments, the absolute position of the terminal includes but is not limited to at least one of the following:
[0125] The absolute location of the A-IoT device closest to the terminal detected by the terminal;
[0126] The absolute location of the A-IoT device with the largest reflected signal strength detected by the terminal;
[0127] The absolute location of the A-IoT device whose reflected signal strength detected by the terminal exceeds the reflected signal strength threshold;
[0128] The center position of the absolute positions of at least two A-IoT devices detected by the terminal.
[0129] For example, the absolute position of the terminal can be represented by longitude and latitude.
[0130] In some implementations, a terminal can determine its absolute position based on the absolute position of an A-IoT device. For example, if the terminal detects that the absolute position of the A-IoT device closest to it is P, then the terminal's absolute position is P. For another example, if the terminal detects that the absolute position of the A-IoT device with the highest reflected signal strength is P, then the terminal's absolute position is P. For another example, if the terminal detects that the absolute position of the A-IoT device with a reflected signal strength exceeding a reflected signal strength threshold is P, then the terminal's absolute position is P.
[0131] Exemplarily, the absolute position of the terminal includes the center position of the absolute positions of at least two A-IoT devices detected by the terminal, so that the distance between the terminal and the at least two A-IoT devices is equal or close.
[0132] For example, based on the absolute positions of two A-IoT devices, the midpoint is calculated to be the terminal location. Without loss of generality, expressing the position in coordinates, A-IoT device A is located at [X1, Y1], and A-IoT device B is located at [X2, Y2]. The UE location is then [(X1+X2) / 2, (Y1+Y2) / 2].
[0133] For another example, based on the absolute positions of three A-IoT devices, the center of the circumscribed circle of the triangle formed by the absolute positions of the three A-IoT devices is taken as the UE position.
[0134] In some embodiments, the relative position of the terminal includes but is not limited to at least one of the following:
[0135] The relative position of the A-IoT device closest to the terminal detected by the terminal;
[0136] The relative position of the A-IoT device with the largest reflected signal strength detected by the terminal;
[0137] The relative position of the A-IoT device whose reflected signal strength detected by the terminal exceeds the reflected signal strength threshold;
[0138] The average of the relative positions of at least two A-IoT devices detected by the terminal.
[0139] It should be noted that the relative position of an A-IoT device is the position information of the A-IoT device relative to a reference point. For example, the reference point is a specific absolute position, a base station position, or a TRP position.
[0140] Exemplarily, the relative position of the terminal includes the average value of the relative positions of at least two A-IoT devices detected by the terminal. If the relative position is a distance, the average value calculated based on the distance of at least two A-IoT devices is the terminal position.
[0141] For example, the relative position of the terminal may include the relative position of a randomly selected A-IoT device from at least two A-IoT devices detected by the terminal, or the relative position of an A-IoT device selected according to a specific rule from at least two A-IoT devices detected by the terminal. Optionally, the specific rule may be agreed upon by a protocol, or may be configured by the network side.
[0142] In some embodiments, the proximity indication includes, but is not limited to, at least one of the following:
[0143] Information indicating at least one specific A-IoT device that the terminal approaches or leaves;
[0144] Information indicating that the terminal is approaching or leaving at least one specific A-IoT device;
[0145] Information indicating whether the terminal is approaching or leaving all specific A-IoT devices.
[0146] The proximity can be understood as that the reflected signal strength of the specific A-IoT device measured by the UE exceeds the reflected signal strength threshold; or the distance between the UE and the specific A-IoT device is lower than a certain configured or agreed distance threshold.
[0147] Similarly, the departure can be understood as that the reflected signal strength of the specific A-IoT device measured by the UE is lower than the reflected signal strength threshold; or, the distance between the UE and the specific A-IoT device is higher than the distance threshold.
[0148] In some embodiments, the positioning method 200 further includes:
[0149] The terminal sends the location information of the terminal to the network side device.
[0150] In this embodiment, the terminal reports its location information, so that the network side can perform corresponding operations based on the location information of the terminal, such as assisted handover or measurement configuration.
[0151] Exemplarily, the location information of the terminal may be carried by at least one of the following:
[0152] Measurement report, terminal assistance message.
[0153] In some embodiments, the positioning method 200 further includes:
[0154] The terminal receives first configuration information from the network side device;

[0157] The proximity indication is used to indicate that the terminal is approaching or leaving the at least one specific A-IoT device.
[0158] Exemplarily, the proximity indication can be determined based on a reflected signal strength threshold used to determine approach or departure. For example, if the terminal detects that the reflected signal strength of a specific A-IoT device is greater than or equal to the reflected signal strength threshold used to determine approach or departure, the terminal determines that it is approaching the specific A-IoT device; if the terminal detects that the reflected signal strength of a specific A-IoT device is less than the reflected signal strength threshold used to determine approach or departure, the terminal determines that it is moving away from the specific A-IoT device.
[0159] In one embodiment, the reflected signal strength threshold for determining approach or departure includes a reflected signal strength threshold for determining approach or departure from at least one specific A-IoT device, or includes a reflected signal strength threshold for determining approach or departure from all specific A-IoT devices. It will be understood that the reflected signal strength threshold for determining approach or departure is the reflected signal strength threshold for determining the proximity indication.
[0160] In one embodiment, the reflected signal strength threshold for determining approach or departure is a reflected signal strength threshold for determining whether to report an approach indication.
[0161] Exemplarily, the reference point information corresponding to the relative position of the A-IoT device may include at least one of the following: specific absolute position information, a specific base station identifier, a specific TRP identifier, and a specific cell identifier.
[0162] In the embodiment of the present application, the above S220 may specifically include:

[0166] In some embodiments, before the terminal obtains the A-IoT information, the positioning method 200 further includes:
[0167] The terminal receives second configuration information from the first entity;
[0168] The second configuration information includes at least one of the following:
[0169] Identification information of at least one specific A-IoT device, reference point information corresponding to the relative position of the A-IoT device, and location information associated with the at least one specific A-IoT device.
[0170] In some embodiments, the first entity may be a third-party server or a third-party network element.
[0171] In some embodiments, the first entity may be a core network element, or the first entity may be an application function (AF).
[0172] In the embodiment of the present application, the above S220 may specifically include:
[0173] The terminal determines the location information of the terminal based on the A-IoT information and the second configuration information.
[0174] Therefore, in the embodiments of the present application, the terminal obtains A-IoT information and determines its location information based on the A-IoT information. This means that the terminal can be positioned with the assistance of an A-IoT device.
