[0003] In the Artificial Intelligence of Things (AIoT) communication system, it is usually necessary to locate related devices.

[0004] At present, due to the narrow communication bandwidth and weak measurement capabilities of the relevant equipment in the AIOT communication system, the positioning equipment (used to locate the relevant equipment) is far away from the relevant equipment, so it is impossible to locate the relevant equipment through existing positioning technologies and processes.

[0005] Therefore, how to complete the positioning of related equipment in the AIOT communication system has become a technical problem that needs to be solved urgently. Summary of the Invention

[0236] To facilitate a clear description of the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0237] 1. AIoT

[0238] AIoT aims to provide a low-power, low-complexity, and low-cost IoT solution. Within the Third Generation Partnership Project (3GPP) standards framework, it is a lower-capability standard than narrowband IoT (NB-IoT). Within non-3GPP frameworks, it targets the radio frequency identification (RFID) market, offering comparable yet superior technical solutions.

[0239] The demand for AIoT is to address scenarios not covered by current 3GPP technologies, such as the following three scenarios:

[0240] 1) Extreme environmental conditions, such as high pressure, extremely high / low temperature, and humid environment;

[0241] 2) Strong demands for one or more of ultra-low complexity, very small device size / form factor (e.g., millimeter thickness), maintenance-free (e.g., no need for traditional battery replacement of the device), and longer life cycle;

[0242] 3) Device scenarios where traditional battery drive is not suitable.

[0243] AIoT is also an IoT service that aims to provide AIoT devices with features such as low power consumption and low complexity, very small size, and a longer lifecycle. AIoT devices are powered by energy harvesting and can be battery-free or have limited energy storage capabilities (i.e., using capacitors). They can communicate with other devices without traditional power supplies and / or avoid human intervention for charging or replacement.

[0244] Typically, IoT devices that support ambient power do not have traditional batteries. Instead, the devices themselves use energy harvested from radio waves or any other form of energy available in the specific use case. For example, in some scenarios, AIoT devices can harvest energy from radio waves, which may originate from the 5G NR network entity or the terminal device. In other scenarios, IoT devices that support ambient power can harvest energy from solar energy, light, motion / vibration, heat, pressure, or any other source of energy.

[0245] AIoT devices can be divided into the following three types:

[0246] Type 1: This type of AIoT device has no energy storage capability, no independent signal generation / amplification, and can use backscatter transmission;

[0247] Type 2: This type of AIoT device has energy storage capabilities, does not generate independent signals, and can participate in backscatter transmission. The stored energy can be used to amplify the backscatter signal.

[0248] Type 3: This type of AIoT device has energy storage capabilities and generates independent signals.

[0249] 2. Inventory

[0250] Inventory management refers to the process by which a second device identifies a first device and obtains its identity (ID). This process can be applied in a variety of scenarios, such as logistics management or warehouse management. It can be particularly effective in scenarios with a large number of devices, saving significant manpower and resources while enabling quick and accurate inventory counts.

[0251] 3. RFID technology

[0252] RFID technology is a contactless automatic identification technology that enables contactless two-way data communication between network devices and terminal devices through wireless radio frequency. Network devices (such as readers) can use wireless radio frequency to read and write terminal devices (such as tags), thereby achieving the purpose of target identification and data exchange.

[0253] 4. Other terms

[0254] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0255] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, c can be single or multiple.

[0256] In the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the terms "first chip" and "second chip" are used solely to distinguish between different chips and do not define their order. Those skilled in the art will understand that terms such as "first" and "second" do not define the quantity or execution order, and do not necessarily define differences.

[0257] It should be noted that the phrases "when (at) ...", "when (in) the case of ...", or "if ..." in the embodiments of the present application can refer to the instant when a certain situation occurs or a period of time after the occurrence of a certain situation, and the embodiments of the present application do not specifically limit this. In addition, the display interface provided in the embodiments of the present application is only an example, and the display interface can also include more or less content.

[0258] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0259] Currently, due to the narrow communication bandwidth of devices in AIOT communication systems and the long distance between positioning devices (used to locate these devices), existing positioning technologies and processes cannot accurately locate these devices. Therefore, how to trigger the positioning of these devices in AIOT communication systems has become a pressing technical challenge.

[0260] To achieve device positioning in an AIOT communication system, the present application provides a positioning method in which a device to be positioned receives a first message sent by a first node and receives or sends a reference signal based on the first message. The location information of the positioning device can be determined based on the reference signal.

[0261] First, with reference to FIG1 , the application scenario of the positioning method provided in this application is described.

[0262] Figure 1 is a schematic diagram of an application scenario provided by an embodiment of the present application. As shown in Figure 1 , the application scenario includes: a first node, a device to be located, and multiple auxiliary positioning devices. The first node, the device to be located, and the multiple auxiliary positioning devices can communicate with each other.

[0446] Optionally, the signal measurement information does not include the position information of the auxiliary positioning device; when receiving multiple signal measurement information, the first node determines the target measurement information from the multiple signal measurement information;

[0447] According to the identifier of the auxiliary positioning device in the target measurement information, determine the second preset position corresponding to the identifier among multiple second preset positions, and determine the second preset position corresponding to the identifier as the position information of the auxiliary positioning device;

[0448] According to the position information of the auxiliary positioning device and the strength information of the reference signal in the target measurement information, determine the position information of the device to be located.

[0449] Optionally, the target measurement information is signal measurement information in one or more of the following methods 11 to 13.

[0450] Mode 11: The target measurement information is signal measurement information including the identifier of the device to be located.

[0452] Mode 13: The positioning process identifier in the target measurement information is the same as the positioning process identifiers in the first message and the second message.

[0453] In the embodiment of the present application, the position information of the device to be located is determined according to the strength information of the reference signal in the target measurement information, so as to achieve a rough estimation of the device to be located and estimate the approximate position range of the area where the device to be located is located.

[0472] S508. Device B determines a sending period (eg, T2) according to the second message, and sends a reference signal within T2.

[0473] Specifically, the execution method of S507-S08 is the same as the execution method of S505-S506, and the execution process of S507-S08 is not repeated here.

[0474] In an embodiment of the present application, the auxiliary positioning device sends reference signals in different sending time periods, and the device to be positioned receives reference signals in different time periods, which can improve the quality of the received reference signals and thus improve the accuracy of the location information of the device to be positioned.

[0475] Based on the above embodiment, the positioning configuration information including reference signal reception resources or reference signal transmission resources is taken as an example, and in combination with the embodiment of FIG6 , the positioning of the device to be positioned by the methods in S303b and S304b is described.

[0476] FIG6 is a fourth flow chart of a positioning method according to an embodiment of the present application. As shown in FIG6 , the positioning method includes:

[0477] S601: A first node sends a first message to a device to be located.

[0478] S602: The first node sends a second message to the auxiliary positioning device.

[0479] S603: When the fourth condition is met, the auxiliary positioning device sends a reference signal to the device to be positioned.

[0480] In one possible implementation, the fourth condition includes one or more of the following:

[0481] The second identifier in the second message is the same as the identifier of the auxiliary positioning device;

[0482] The second positioning indication in the second message is used to instruct sending a reference signal;

[0483] The positioning configuration information in the second message includes reference signal sending resources.

[0484] In one possible implementation, the reference signal includes one or more of the following:

[0485] Identification of auxiliary positioning equipment;

[0486] Location information of auxiliary positioning devices;

[0487] Locate the process identifier.

[0488] In the embodiment of the present application, the location information of the auxiliary positioning device may be absolute location information, virtual location information, predefined location information, etc.

[0489] S604: When the first condition is met, the device to be positioned receives a reference signal sent by the auxiliary positioning device.

[0490] In one possible implementation, the first condition includes one or more of the following:

[0491] The first identifier in the first message is the same as the identifier of the device to be located;

[0492] The first positioning indication in the first message is used to indicate receiving a reference signal;

[0493] The positioning configuration information in the first message includes reference signal reception resources.

[0494] S605: When the second condition is met, the device to be located measures the reference signal to obtain strength information of the reference signal.

[0495] The second condition includes one or more of the following:

[0496] The second identifier is the same as the identifier of the auxiliary positioning device;

[0497] The positioning procedure identifier in the first message is the same as the positioning procedure identifier in the reference signal.

[0498] The strength information of the reference signal in S605 is similar to the strength information of the reference signal in S405 and will not be described again here.

[0499] It should be noted that, when there are multiple auxiliary positioning devices, after S604 and S605 , the strength information of multiple reference signals and the position information of multiple auxiliary positioning devices are obtained.

[0500] S606: The device to be located determines the location information of the device to be located according to the strength information of the reference signal and the location information of the auxiliary positioning device in the reference signal.

[0501] Furthermore, the location information of the device to be located is determined based on the strength information of the multiple reference signals and the location information of the multiple auxiliary positioning devices.

[0502] In the embodiment of the present application, the reference signal includes the identifier of the auxiliary positioning device, which enables the device to be positioned to distinguish the association between the reference signal and the auxiliary positioning device, ensuring that the device to be positioned can determine its own location information.

[0503] S607a: When the location information of the device to be located is the same as the first preset location information of the device to be located, the device to be located sends signal measurement information of the reference signal to the first node.

[0504] The first preset location information is location information pre-stored in the device to be located.

[0505] In a possible embodiment, the signal measurement information includes one or more of the following:

[0506] Reference signal strength information;

[0507] Identification of auxiliary positioning equipment.

[0508] Optionally, when the location information is the same as the first preset location information of the device to be located, the device to be located may also be configured to not send signal measurement information of the reference signal to the first node.

[0509] Optionally, when the location information is the same as the first preset location information of the device to be positioned, an identifier of an auxiliary positioning device may be sent to the first node separately, where the identifier of the auxiliary positioning device is the identifier of the positioning device that sends the reference signal.

[0510] S607b: When the location information of the device to be located is different from the first preset location information of the device to be located, the device to be located sends an alarm message to the first node, where the alarm message includes the location information of the device to be located and / or an identifier of the device to be located.

[0511] S608: The first node triggers the positioning process of the device to be positioned again according to the alarm information.

[0512] Optionally, the re-triggered positioning process of the device to be positioned may differ from S601 to S608 in that: the positioning process identifier is different, the second identifier may be different, and the positioning configuration information is different; and the same as S601 to S608 is that: the first identifier is the same.

[0513] Optionally, the positioning process for the device to be positioned that is triggered again may be a positioning process with higher precision.

[0514] In the embodiment of the present application, whether the device to be located has moved is determined based on the alarm information, thereby triggering a positioning process for the device to be located and improving the positioning reliability of the device to be located.

[0515] In the above embodiment, the signal in the AIoT communication system is weak, so the auxiliary positioning device is used to locate the device to be positioned, so as to achieve the purpose of locating the device to be positioned in the AIoT communication system.

[0516] Furthermore, in the above embodiment, considering that it is difficult for the auxiliary positioning device and the device to be positioned to establish a direct communication link, whether the positioning process index identifies the message or reference signal is related to itself can reduce signaling overhead.

[0517] Based on Figure 6, when the positioning configuration information includes time domain related configuration, the execution process in S601-S604 is the same as the execution process type of the embodiment of Figure 5, and will not be repeated here.
