Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a deformation sensing method and a communication device. Background Art

[0002] In order to maintain the safety of infrastructure such as bridges and buildings, deformation detection needs to be carried out regularly. The traditional method of manually checking deformation not only requires a lot of manpower and material resources, but also the detection accuracy cannot be guaranteed.

[0003] Currently, micro-deformations of infrastructure can be detected through laser interferometers or millimeter-wave interferometers. However, the maintenance and measurement costs of high-precision interferometers are high, and the interferometers need to be manually moved to the vicinity of the target for measurement on a regular basis, resulting in poor timeliness in obtaining the deformation of the target. Summary of the invention

[0004] The embodiments of the present application provide a deformation sensing method and a communication device, which can reduce the deformation measurement cost and improve the timeliness of obtaining the deformation of a sensed object.

[0005] In a first aspect, a deformation sensing method is provided, comprising: a first node sends a sensing signal. A second node receives the sensing signal and obtains at least one sub-signal of the sensing signal reaching the second node through at least one transmission path. The second node sends first information to the sensing node, the first information being used to indicate a first phase, the first phase being the phase of the first sub-signal in the at least one sub-signal, or the first phase being the phase difference between the first sub-signal and the second sub-signal in the at least one sub-signal, wherein the first sub-signal is a sub-signal of the sensing signal reaching the second node after being reflected by a sensing point on the sensing object, and the second sub-signal is a sub-signal of the sensing signal reaching the second node through a reference path in the at least one transmission path. The sensing node determines whether the sensing object is deformed based on the first phase and the reference phase.

[0006] According to the above scheme, it is possible to use the wireless communication nodes in the existing mobile communication network and the wireless signals to sense the deformation of the sensed object, so as to realize the real-time and automatic deformation sensing of the sensed object such as the infrastructure. It reduces the cost of measuring deformation, improves the timeliness of obtaining the deformation of the target to be measured, and can timely realize the safety maintenance of infrastructure such as bridges and buildings.

[0007] In combination with the first aspect, in some implementations of the first aspect, the method further includes: the sensing node sends second information to the first node, the second information is used to request the first node to perform sensing measurement of the sensed object, and the second information includes location information of the sensed point on the sensed object. The first node sends third information to the sensing node, the third information is used to determine to perform the sensing measurement, and the third information is also used to indicate configuration information of the sensing signal.

[0008] According to the above scheme, the sensing node can configure the first node to perform sensing measurement, so that the first node determines the position of the sensed point according to the configuration of the sensing node, thereby determining the resource configuration of the sensing signal (such as one or more of time domain resources, frequency domain resources or spatial domain resources), and feeds back to the sensing node so that the sensing node notifies the receiving end of the sensing signal (i.e., the second node), so that the first node and the second node can realize the sensing measurement of whether the sensed body is deformed through the sensing measurement configuration of the sensing node.

[0009] In combination with the first aspect, in some implementations of the first aspect, the method further includes: the sensing node sending fourth information to the second node, where the fourth information is used to configure the second node to perform sensing measurement, and the fourth information is used to indicate one or more of the following information:

[0010] Configuration information of the perception signal, receiving beam information of the perception signal, information of the perceived point, information of the reference path, or position information of a reference point in the reference path that reflects the perception signal.

[0011] According to the above solution, the sensing node may configure the second node to perform sensing measurement, so that the second node determines information of the sensing signal and information of the sensed point according to the configuration of the sensing node, thereby performing sensing measurement by receiving the sensing signal.

[0012] In combination with the first aspect, in some implementations of the first aspect, the sensing node determines whether the sensed object is deformed according to the first phase and the reference phase, including: the sensing node determines whether the sensed point is displaced according to the phase difference between the first phase and the reference phase and the wavelength of the sensing signal. If the sensed point is displaced, the sensed object is deformed, and if the sensed point is not displaced, the sensed object is not deformed.

[0013] According to the above scheme, the sensing node can judge whether the sensed object has been displaced based on the first phase fed back by the second node, thereby determining whether the sensed object has been deformed. This achieves sensing and measuring whether the sensed object has been deformed by using wireless signals in the mobile communication system.

[0014] In combination with the first aspect, in some implementations of the first aspect, the method further includes: when the sensing node determines that the sensed point has been displaced and the displacement is greater than or equal to a threshold value, sending an alarm message.

[0015] According to the above scheme, the sensing node determines whether the sensed object has deformed based on the sensing signal fed back by the second node, and sends an alarm message if deformation occurs. For example, the sensing node can send an alarm message to the administrator terminal so that the administrator can promptly know that the sensed point has deformed through the alarm message obtained by the terminal.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the reference path is a direct signal path between the first node and the second node; or, the reference path is a transmission path of the perception signal from the first node to the second node after reflection through a reference point.

[0017] According to the above scheme, the first phase is the phase difference between the first sub-signal and the second sub-signal, and the reference path can be a direct signal path or a transmission path that reaches the second node after being reflected from a preset reference point. Since each transmission path of the perception signal has the same or similar system error, the phase of the first sub-signal is subtracted from the phase of the second sub-signal to offset the system error, thereby improving the accuracy of deformation perception.

[0018] In combination with the first aspect, in some implementations of the first aspect, the first node and the second node are different nodes of the same access network device; or, the first node and the second node are nodes of different access network devices respectively.

[0019] In combination with the first aspect, in some implementations of the first aspect, the perception node is a core network node, or the perception node and the second node are different nodes of the same access network device.

[0020] The solution provided in this application can be applied to a variety of deployment scenarios to achieve deformation perception measurement of the perceived object.

[0060] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0061] In the embodiment of the present application, " / " can indicate that the objects associated before and after are in an "or" relationship, for example, A / B can indicate A or B; "and / or" can be used to describe that there are three relationships between the associated objects, for example, A and / or B can indicate: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In order to facilitate the description of the technical solution of the embodiment of the present application, in the embodiment of the present application, the words "first" and "second" can be used to distinguish. The words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit the difference. In the embodiment of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or explanations, and any embodiment or design described as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or design. The use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way for easy understanding. In the embodiments of the present application, at least one (kind) can also be described as one (kind) or more (kinds), and more (kinds) can be two (kinds), three (kinds), four (kinds) or more (kinds), and the present application does not impose any limitation.

[0062] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: long term evolution (LTE) systems, such as LTE frequency division duplex (FDD) systems or LTE time division duplex (TDD), or to fifth generation (5G) communication systems, such as new radio (NR) systems in 5G, or to future communication systems (such as sixth generation (6G) communication systems), or systems integrating multiple communication systems, etc., and the embodiments of the present application are not limited.

[0063] Figure 1 is a communication system architecture diagram applicable to the embodiment of the present application. Figure 1As shown, in the communication system, the user equipment (UE) can be connected to the radio access network through the next-generation base station (ng-eNB) and gNB respectively through the LTE-Uu and / or NR-Uu interface; the radio access network is connected to the core network through the access and mobility management function (AMF) node through the NG-C interface. Among them, the next-generation radio access network (NG-RAN) includes one or more ng-eNBs; NG-RAN may also include one or more gNBs; NG-RAN may also include one or more ng-eNBs and gNBs. The ng-eNB is an LTE base station accessing the 5G core network, and the gNB is a 5G base station accessing the 5G core network. The core network may include functional nodes such as AMF nodes and location management function (LMF) nodes. Among them, the AMF node is used to implement functions such as access management, and the LMF node is used to implement functions such as positioning. The AMF node is connected to the LMF node through the NL1 interface. LMF is used to provide UE with different types of location services and other functions, including but not limited to UE positioning and transmitting auxiliary data to the UE. The control plane of LMF is the enhanced serving mobile location center (E-SMLC), which is used to manage the coordination and scheduling of resources required for UE location. The user plane of LMF is the secure user plane location (SUPL) positioning platform (SLP), which can interact and transmit on the user plane through the SUPL protocol. A UE that supports SUPL can be called a SET.

[0064] It should be understood that Figure 1 This is only a schematic diagram of the communication system architecture of an embodiment of the present application, but the present application is not limited to this. The communication method provided in the embodiment of the present application can also be applied to other communication system architectures.

[0065] The access network node provided in the embodiment of the present application may be located in a radio access network (RAN). It may also be sometimes referred to as an access network device, a RAN entity or an access node, etc., which constitutes a part of a communication system and can be used to assist a terminal in achieving wireless access. The RAN may include multiple access network nodes, which may be nodes of the same type or nodes of different types. The present application does not limit the specific technology and specific device form used by the access network node.

[0066] In one possible scenario, the access network node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The access network node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the access network node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the access network node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network node in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the access network node.

[0067] In another possible scenario, multiple access network nodes collaborate to assist the terminal in achieving wireless access, and different access network nodes respectively implement part of the functions of the base station. For example, the access network node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0068] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0069] Since the maintenance and measurement costs of high-precision interferometers are high, and it is necessary to manually move the interferometer to the vicinity of the target to be measured regularly for measurement, the timeliness of obtaining the deformation of the target to be measured is poor. To address this problem, this application proposes that the deformation of the target to be measured can be sensed based on wireless signals using mobile communication networks. Since mobile communication networks have achieved wide coverage, the use of wireless signals for sensing can achieve real-time and automated deformation sensing of infrastructure targets to be measured (referred to as sensed objects in the embodiment). This reduces the cost of measuring deformation, improves the timeliness of obtaining the deformation of the target to be measured, and can timely achieve safety maintenance of infrastructure such as bridges and buildings.

[0070] Figure 2 FIG. 2 is a schematic flow chart of a deformation sensing method 200 provided in an embodiment of the present application. Figure 2The system includes a first node, a second node and a sensing node. The first node is a node that sends a sensing signal, and the second node is a node that receives a sensing signal. The sensing node is a node that determines whether a sensed object is deformed based on the transmission of the sensing signal from the first node to the sensed object and then to the second node.

[0071] The first node and the second node may be access network nodes. In one implementation, the first node and the second node belong to different access network devices, such as the first node belongs to the first access network device and the second node belongs to the second access network device, and the access network device may be a base station, such as an eNB or a gNB. In another implementation, the first node and the second node belong to the same access network device, such as the first node and the second node may be a transmitting antenna (or antenna array, panel, etc.) and a receiving antenna (or antenna array, panel, etc.) of an access network device, respectively, or the first node and the second node may be different DUs or RUs of an access network device, respectively. When the first node and the second node belong to the same access network device, the first node and the second node may be located at the same location or at different locations, such as the first node and / or the second node may be a remote unit of the access network node.

[0072] The perception node may be a core network node, such as a perception node may be a device or component that provides a perception function in the core network, for example, the perception node may be an AMF node or an LMF node. Alternatively, the perception node may belong to an access network device, such as the perception node may belong to the same access network device as the second node, or the first node, the second node and the perception node may belong to the same access network device, that is, one access network device may sense whether the perceived object is deformed. If the first node and / or the second node may be a DU or RU of an access network device, the perception node may be a node in the access network device that has data processing capabilities.

[0073] This application does not limit the specific implementation forms of the first node, the second node and the perception node.

[0074] like Figure 2 The deformation sensing method 200 shown includes but is not limited to the following S201 to S204.

[0075] S201: The first node sends a perception signal.

[0076] Exemplarily, the perception signal may be a pilot signal (or referred to as a reference signal), and the sequence for generating the pilot signal is known to the first node and the second node. For example, the first node and the second node may learn the sequence for generating the pilot signal from the LMF node. Or the first node and the second node may reach a consensus on the sequence for generating the pilot signal through information interaction. This application is not limited to this.

[0077] S202: The second node receives a perception signal from the first node, and obtains at least one sub-signal of the perception signal that reaches the second node through at least one transmission path.

[0078] The at least one transmission path includes at least a transmission path in which the perception signal is transmitted from the first node to the perceived point on the perceived object, and then is reflected by the perceived point to reach the second node. The transmission path can be called a first transmission path, and the sub-signal transmitted through the first transmission path is called a first sub-signal.

[0079] According to the different deployment modes of the first node and the second node in the specific implementation, the following scenarios can be used:

[0080] Scenario 1: The first node and the second node are deployed in different locations, for example Figure 3 As shown, after the first node sends the perception signal, one transmission path of the perception signal is to reach the second node after being reflected by the perceived point on the perceived object. Optionally, the perception signal can also reach the second node from the first node through a direct signal path without being reflected by other objects, and / or the perception signal can also reach the second node through reflections from other objects, such as through Figure 3 The reference point shown reflects off the second node.

[0081] In this scenario 1, the first node and the second node may belong to the same access network device but are deployed at different locations. Alternatively, the first node and the second node may belong to different access network devices, and the details may refer to the above description. When the first node and the second node belong to different access network devices (such as base stations), the deformation perception method of the perceived object may be called a multi-station perception method.

[0082] Scenario 2: The first node and the second node are deployed at the same location, for example Figure 4 As shown, after the first node sends the sensing signal, the sensing signal is transmitted from the first node to the sensing point of the sensing object, and after being reflected by the sensing point, it returns to the second node along the original path. Optionally, the sensing signal can also be reflected by other objects to reach the second node, such as Figure 4 The reference point shown reflects off the second node.

[0083] In the scenario 2, the first node and the second node may be nodes belonging to the same access network device. When the first node and the second node belong to the same access network device (such as a base station), the deformation sensing method of the sensed object may be called a single-station sensing method.

[0084] The sensed point is located at a preset position on the sensed object. Exemplarily, a corner reflector may be installed on the sensed point, and the corner reflector can make the sub-signal of the reflected sensing signal have stronger energy, thereby improving the reception reliability of the second node for the sensing signal.

[0085] In an optional implementation, the second node is aware of the position of the sensed point, and the second node can use a receiving beam in a corresponding direction to receive a sub-signal of the sensed signal reflected by the sensed point. This can improve the reception reliability of the sensed signal by the second node. For example, the second node can obtain the position information of the sensed point from the sensing node, or the position information of the sensed point can be preconfigured.

[0086] Optionally, the first node may know the position of the sensed point, and the first node may use a transmission beam in a corresponding direction to send a sensing signal to the sensed point, so that the signal energy reaching the sensed point is stronger, and the sensed point can reflect a sub-signal of the sensing signal with stronger energy, thereby improving the reception reliability of the sensing signal by the second node.

[0087] In an optional implementation, the second node may obtain configuration information of the perception signal (or referred to as pilot configuration information) from the first node or the perception node, and the second node may receive the perception signal according to the configuration information of the perception signal.

[0088] Exemplarily, the configuration information may include, but is not limited to, one or more of the following information:

[0089] The sequence information used by the perception signal, the time domain resources and / or frequency domain resources used to carry the perception signal, or the transmission period of the perception signal.

[0090] Optionally, the second node may also obtain configuration information of a receiving / transmitting beam of a perception signal and / or indication information for indicating whether to adopt a single-station perception method or a multi-station perception method from the first node or the perception node.

[0091] S203, the second node sends first information to the perception node, where the first information is used to indicate a first phase, where the first phase is the phase of a first sub-signal in at least one sub-signal, or the first phase is the phase difference between a first sub-signal and a second sub-signal in at least one sub-signal, where the first sub-signal is a sub-signal that reaches the second node after the perception signal is reflected by a perceived point on the perceived object, and the second sub-signal is a sub-signal that reaches the second node after the perception signal passes through a reference path in the at least one transmission path.

[0092] In S202 , the second node receives at least one sub-signal of the perception signal that arrives at the second node via at least one transmission path, including a first sub-signal that arrives at the second node via a first transmission path.

[0093] In the first implementation, the second node can determine the phase θ of the first sub-signal s (t), the second node may send first information to the sensing node, the first information being used to indicate the phase of the first sub-signal, that is, in the first embodiment, the first phase θ1(t) is the phase θ of the first sub-signal s (t), θ1(t)=θ s (t). Accordingly, the sensing node receives the first information from the second node, obtains the phase of the first sub-signal, and can determine whether the sensed object is deformed. For a specific implementation, please refer to the description in S204 below.

[0094] In the second embodiment, the at least one sub-signal acquired by the second node also includes a second sub-signal transmitted to the second node via the reference path, and the second node can determine the phase θ of the first sub-signal. s (t) and the phase θ of the second sub-signal ref (t), and then determine the phase difference Δθ(t) between the first sub-signal and the second sub-signal, which satisfies:

[0095] Δθ(t)=θ s (t)-θ ref (t).

[0096] Since each transmission path of the perception signal has the same or similar system error, subtracting the phase of the first sub-signal from the phase of the second sub-signal can offset the system error, thereby improving the accuracy of deformation perception.

[0097] The second node sends the first information to the sensing node, and the first information is used to indicate the phase difference Δθ(t) between the first sub-signal and the second sub-signal. That is, in the second embodiment, the first phase θ1(t) is the phase difference Δθ(t), θ1(t)=θ ref (t). After the sensing node obtains the phase difference through the first information, it can determine whether the sensed object is deformed. For a specific implementation, please refer to the description in S204 below.

[0098] In Example 1, the reference path may be a direct path of the sensing signal between the first node and the second node. Figure 3 Direct path shown.

[0099] In Example 2, the reference path may be a transmission path for the sensing signal to be transmitted from the first node to the second node after being reflected from the reference point. This path may be referred to as a second transmission path. For example Figure 3 or Figure 4 The reference points shown reflect the reference path of the sensing signal.

[0100] The second node is aware of the location of the reference point. In an optional implementation, the second node may obtain location information of the reference point from the sensing node, and the second node may determine the location of the reference point based on the location information, thereby determining the second sub-signal from multiple sub-signals of the sensing signal received from multiple transmission paths.

[0101] Exemplarily, the location information may include but is not limited to the relative delay or relative delay range of the sub-signal reflected by the reference point compared to the sub-signal of the direct path, or the absolute position coordinates of the reference point, or the position coordinates of the reference point compared to the second node.

[0102] In an optional implementation, the second node may obtain indication information from the sensing node, the indication information being used to indicate that a direct path or a path reflected from a reference point is used as a reference path. The second node may determine the reference path according to the indication information.

[0103] S204: The sensing node determines whether the sensed object is deformed according to the first phase and the reference phase.

[0104] After acquiring the first phase in S203, the sensing node can determine whether the sensed object is deformed according to the first phase and the reference phase.

[0105] In one example, the first phase is the phase of the first sub-signal, and the reference phase may be the signal phase when the perceived object is not deformed, or the reference phase may be the phase of the sub-signal of the perception signal from the first transmission path at time t0 obtained by the perception node from the second node before the first phase is obtained. For example, the reference phase may be the phase of the sub-signal obtained by the second node receiving the perception signal transmitted by the first node for the first time and reaching the second node through the first transmission path. Or the reference phase may be the phase of the sub-signal from the first transmission path obtained by the second node when the perception signal was received the last time before the first phase was obtained.

[0106] In another example, the first phase is the phase difference between the first sub-signal and the second sub-signal, and the reference phase may be the phase difference between the sub-signals transmitted through the first transmission path and the reference transmission path when the sensed object is not deformed. Alternatively, the reference phase may be the phase difference between the sub-signals from the first transmission path and the second transmission path acquired by the second node at time t0 before the sensing node acquires the first phase.

[0107] Specifically, the sensing node can determine whether there is a phase deformation amount according to the first phase θ1(t) and the reference phase θ(t0). The phase deformation satisfy:

[0108]

[0109] like If it is non-zero, it means that there is phase deformation, and the sensing node can determine that the perceived object has deformed. and the wavelength λ of the sensing signal, the distance deformation Δd(t) can be determined, and the distance deformation Δd(t) satisfies:

[0110]

[0111] The distance deformation Δd(t) is the displacement of the sensed point caused by the deformation of the sensed body.

[0112] In an optional implementation, when the sensing node determines that the sensed point has shifted (ie, Δd(t) or When the displacement of the sensed point (i.e., the distance deformation Δd(t)) is greater than or equal to the threshold value, the sensing node sends an alarm message. For example, the sensing node can send an alarm message to the administrator terminal so that the administrator can promptly know the deformation of the sensed point through the alarm information obtained by the terminal.

[0113] According to the above scheme, it is possible to use the wireless communication nodes in the existing mobile communication network and the wireless signals to sense the deformation of the sensed object, so as to realize the real-time and automatic deformation sensing of the sensed object such as the infrastructure. It reduces the cost of measuring deformation, improves the timeliness of obtaining the deformation of the target to be measured, and can timely realize the safety maintenance of infrastructure such as bridges and buildings.

[0114] In an optional implementation, Figure 2 Before S201 in the illustrated embodiment, the first node, the second node and the sensing node may exchange information to implement the sensing measurement configuration. The first node, the second node and the sensing node perform the following steps according to the sensing measurement configuration: Figure 2 Deformation perception measurements shown.

[0115] Specifically, in the perception measurement configuration process, the perception node may send second information to the first node, the second information is used to request the first node to perform perception measurement of the perceived object, and the second information may include location information of the perceived point on the perceived object. Correspondingly, the first node receives third information from the perception node, the third information may be response information of the second information, and is used to confirm the execution of the perception measurement of the perceived object. The third information is also used to indicate resource configuration information of the perception signal.

[0116] The sensing node may request the first node to perform sensing measurement through the second information, and provide the location information of the sensed point on the sensed body of the sensing measurement. The first node may determine whether to accept the sensing measurement based on the second information. For example, the first node may determine whether to receive the request to perform the sensing measurement based on the current service busyness, wireless resource utilization, or the location relationship with the sensed body. If the first node accepts the request for sensing measurement, the first node may perform resource configuration to allocate resources for the sensing signal transmitted when performing the sensing measurement, such as the sequence used, the time domain resources, frequency domain resources or spatial domain resources (such as the transmission beam) carrying the sensing signal. The first node may also determine the transmission period of the sensing signal. The first node may send third information to the sensing node, and notify the first node of the resource configuration information of the sensing signal determined by the third information.

[0117] In the perception measurement process, the perception node may send fourth information to the second node, where the fourth information is used to configure the second node to perform the perception measurement, and the fourth information may be used to indicate one or more of the following information:

[0118] Resource configuration information of the perception signal, receiving beam information of the perception signal, information of the perceived point, information of the reference path, or position information of the reference point reflecting the perception signal in the reference path.

[0119] Among them, the resource configuration information of the perception signal may include one or more of the sequence adopted by the perception signal, the time domain resources carrying the perception signal, the frequency domain resources, and the transmission period of the perception signal. The receiving beam information of the perception signal may include the identifier of the receiving beam, and the perception node may notify the second node through the receiving beam information which specific receiving beam is used to receive the perception signal. The information of the perceived point may include the location information of the perceived point, such as the absolute or relative position coordinates of the perceived point. Or the information of the perceived point may include the identifier of one of the preconfigured multiple perceived points, and the second node may determine the location of the perceived point according to the identifier and the preconfigured information. The information of the reference path may indicate that the reference path is a direct path or a second transmission path. The location information of the reference point may include the absolute or relative position coordinates of the reference point, or the identifier of one of the preconfigured multiple reference points. In an optional implementation, the fourth information also indicates the type of phase parameter fed back by the second node to the perception node, such as the fourth information indicates that the second node feeds back the phase of the first transmission path, or the phase difference of the signal between the first transmission path and the second transmission path. In the case where the fourth information indicates that the second node feeds back the phase difference of the signal between the first transmission path and the second transmission path, the fourth information may include the position information of the reference point of the reflected perception signal in the reference path. However, the present application is not limited thereto, and the type of phase parameter fed back by the second node to the perception node may be predefined.

[0120] Correspondingly, the second node receives the fourth information from the sensing node, receives the sensing signal according to the fourth information, and after determining the first phase, sends the sensing measurement information (i.e., an example of the above-mentioned first information) to the sensing node. The sensing measurement information is used to indicate the first phase. Optionally, the sensing measurement information also includes one or more of the time information corresponding to the first phase, the resource information of the sensing signal, or the information of the sensed point.

[0121] Optionally, before sending the fourth information to the second node, the perception node may send request information to the second node to request the second node to perform perception measurement. When the second node confirms receipt of the request, the second node sends response information to the perception node to confirm receipt of the request, so that the perception node can send the fourth information to the second node.

[0122] It should be understood that the present application is not limited to the above implementation manner, and the sensing node may instruct the first node and the second node to perform sensing measurement, and the first node and the second node may reach a consensus on the resource configuration of the sensing signal through information interaction.

[0123] In the present application, the perception node may be a functional node in the core network, such as the perception node may be an AMF node or an LMF node. When the perception node is an LMF node, the interaction information between the perception node and the first node and the second node may be carried in a positioning protocol appendix message, such as a positioning protocol appendix message may be an LTE positioning protocol appendix (LTE positioning protocol annex, LPPa) message or an NR positioning protocol appendix (NR positioning protocol annex, NRPPa) message. Specifically, the request information (such as the second information mentioned above) sent by the perception node to the first node and the second node may be an NRPPa positioning information request (NRPPa message-Positioning information request) message, and the response information (such as the third information and the fourth information mentioned above) sent by the first node and the second node to the perception node may be an NRPPa positioning information response (NRPPa message-Positioning information response) message. However, the present application is not limited to this.

[0124] In other implementations, the sensing node may also be a node in the access network, such as the sensing node may be an access network node independent of the first node and the second node, or the sensing node may belong to the same access network device as the first node or the second node, or the sensing node, the first node and the second node may belong to the same access network device. This application does not limit the specific deployment form.
