Description

Technical Field

[0001] This application relates to the field of communications, and in particular, to a measurement method and related devices. Background Art

[0002] Deformation detection is widely used in many fields, such as industrial safety, bridge / dam safety, construction, etc. Through deformation detection, potential safety problems can be discovered in a timely manner, so as to carry out maintenance and avoid safety accidents. Deformation detection is to measure a specific target for a long time to obtain the changes of the target. It can be seen that how to measure a specific target is crucial in the process of deformation detection.

[0003] Therefore, there is an urgent need to provide a method that can complete the measurement of a specific target. Summary of the Invention

[0004] This application provides a measurement method and related devices, aiming to complete the measurement of a specific target.

[0005] In a first aspect, this application provides a measurement method. This method can be executed by a measurement device, or by components (such as chips, chip systems, etc.) in the measurement device, or, alternatively, by a logic module or software that can implement all or part of the functions of the measurement device. This application does not make any limitations in this regard.

[0006] Exemplarily, the method includes: receiving a measurement request from a first network element, where the measurement request is used to request measurement of a target, and the measurement request includes information about the above-mentioned target; and measuring the above-mentioned target according to the information about the target.

[0007] In this application, the first network element can be a network element for providing sensing / measurement / detection / location functions. The first network element can be deployed on the access network side or the core network side. This application does not make any limitations in this regard. The first network element can be, for example, a location management function (LMF) network element or a sensing management function (SMF) network element, etc. This application does not make any limitations on the specific type of the first network element.

[0008] In this application, the above-mentioned target can be a passive target. A passive target refers to an object that cannot actively send signals, such as a bridge, a gasoline tank, etc. The above-mentioned target can also be an active target. An active target refers to an object that can actively send signals, such as a mobile phone, a computer, etc. When the above-mentioned target is an active target, the measurement of the target by the measurement device does not depend on the signal actively sent by the target. In other words, the signal used to measure the above-mentioned target is not sent by the target.

[0009] In the above technical solution, the measurement device can receive a measurement request from the first network element, and the measurement request is used to request measurement of a target. In other words, the measurement device can determine which target to measure, and further complete the measurement of the above target according to the information of the target included in the measurement request, providing a method for measuring a known (or specific) target. In addition, for the first network element, it can flexibly specify which target to measure.

[0010] Combined with the first aspect, in some possible implementation manners of the first aspect, the information of the above target includes information indicating the identifier of the target.

[0011] The identifier of the above target is used to identify the target, and different identifiers can be used to distinguish different targets. On the one hand, the identifier of the above target can be used to distinguish the measurement results corresponding to different targets when the measurement device reports the measurement results to the first network element; on the other hand, when the position of the target does not change, the first network element can directly indicate the identifier of the target to the measurement device next time, instead of indicating the specific information of the above target, such as the position of the target, or the distance between the target and the measurement device, etc., which is beneficial to reducing signaling overhead.

[0012] It can be understood that when the position of the target does not change and the first network element directly indicates the identifier of the target to the measurement device next time, the measurement device can determine the information of the target corresponding to the target according to the identifier of the above target, such as the position of the target, the distance between the target and the measurement device, the orientation of the target, etc.

[0013] Combined with the first aspect, in some possible implementation manners of the first aspect, the information of the above target further includes one or more of the following: information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device.

[0014] Among them, the information indicating the position of the target can be, for example, the position coordinates of the target, where the position coordinates of the target can be the absolute position coordinates or relative position coordinates of the target, and the present application does not make any limitation thereto.

[0015] The orientation of the above target can be the absolute orientation or relative orientation. The absolute orientation can be, for example, the orientation of the target relative to the measurement device, and the relative orientation can be, for example, the orientation of the above target (denoted as target 1) relative to another target (denoted as target 2), and the present application does not make any limitation thereto.

[0016] The angle of the above target can be the angle of the target relative to the reference direction, or in other words, the included angle between the line connecting the target and the measurement device and the reference direction.

[0017] The distance between the above-mentioned target and the measurement device can be an absolute distance or a relative distance. Among them, the absolute distance can be, for example, the distance value or distance range between the target and the measurement device. The relative distance can be, for example, the distance between the target and the measurement device relative to a reference distance, and the above-mentioned reference distance can be, for example, the distance between the measurement device and another target.

[0018] By means of the information indicating the above-mentioned target, the first network element helps the measurement device to determine the beam direction for transmitting the reference signal, and then transmits the reference signal in this beam direction to complete the measurement of the target. In this way, even if the position of the above-mentioned target changes, the measurement device can know the beam direction for transmitting the reference signal to complete the measurement of the target.

[0019] Optionally, the information of the above-mentioned target may include one or more of the following: information indicating the identity of the target, information indicating the position of the target; information indicating the azimuth or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device.

[0020] That is to say, the information of the above-mentioned target may also include one or more of the following: information indicating the position of the target; information indicating the azimuth or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device, and does not include the information indicating the identity of the target. In this way, the measurement device can also determine the corresponding target according to the information of the above-mentioned target.

[0021] In combination with the first aspect, in some possible implementation manners of the first aspect, the above method further includes: sending a first message to the first network element, where the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the position where the measurement device is located, the direction of the antenna panel of the measurement device, or the number of antenna elements of the measurement device.

[0022] Among them, the above-mentioned first message can be actively reported by the measurement device or requested to be reported by the first network element, and this application does not make a limitation on this.

The direction of the antenna panel of the measurement device can be used by the first network element to determine which measurement device to select for measurement based on the direction of the target and the direction of the antenna panel. Additionally, the first network element can also determine the measurement device used to measure the target based on the number of antenna elements. For example, it can select a measurement device with a larger number of antenna elements to measure the target.

[0024] In combination with the first aspect, in some possible implementation manners of the first aspect, the above method further includes: receiving a second message from the first network element, where the second message is used to request configuration information of a reference signal resource, the reference signal resource is used to transmit a reference signal, and the reference signal is used to measure the above target; sending the configuration information to the first network element.

[0025] The above configuration information can be used to configure one or more of the following: time domain resources, frequency domain resources, or spatial domain resources, etc. Exemplarily, the above configuration information includes the period of the reference signal, one or more beam directions, or at least one time-frequency resource. Among them, the beam direction indicated by the first network element for transmitting the reference signal mentioned above can be a subset of the above one or more beam directions. That is to say, the first network element can select the beam direction for measuring the target from the one or more beam directions reported by the measurement device and indicate it to the measurement device.

[0026] In combination with the first aspect, in some possible implementation manners of the first aspect, the above method further includes: sending a measurement result to the first network element, where the measurement result is obtained by measuring the above target, and the measurement result includes one or more of the following: the identifier of the target, time measurement information, angle measurement information, energy measurement information, or phase measurement information.

[0027] Among them, the time measurement information includes, but is not limited to: time of arrival (TOA), time difference of arrival (TDOA), round trip time (RTT), or reference signal time difference (RSTD). The angle measurement information includes, but is not limited to: angle of departure (AOD) or angle of arrival (AOA). The energy measurement information includes, but is not limited to: received signal strength (RSS). The phase measurement information includes, but is not limited to: the phase or phase difference of the reference signal.

[0028] In a second aspect, the present application provides a measurement method, which can be executed by a first network element, or by components (such as chips, chip systems, etc.) configured in the first network element, or can also be implemented by a logic module or software capable of implementing all or part of the functions of the first network element. The present application does not make any limitations in this regard.

[0029] Exemplarily, the method includes: generating a measurement request for requesting measurement of a target, where the measurement request includes information about the above-mentioned target; and sending the above-mentioned measurement request to a measurement device.

[0030] In the above technical solution, the first network element can send a measurement request to the measurement device to request measurement of a specific (or known) target, providing a method for measuring a known (or specific) target. That is to say, the first network element can flexibly specify which target to measure.

[0031] In combination with the second aspect, in some possible implementation manners of the second aspect, the information about the above-mentioned target includes information indicating the identifier of the target.

[0032] The identifier of the above-mentioned target is used to identify the target, and different identifiers can be used to distinguish different targets. On the one hand, the identifier of the above-mentioned target can be used to distinguish the measurement results corresponding to different targets when the measurement device reports the measurement results to the first network element; on the other hand, when the position of the target has not changed, the first network element can directly indicate the identifier of the target to the measurement device next time, instead of indicating the specific information of the above-mentioned target, such as the position or the distance between the target and the measurement device, etc., which is beneficial to reducing signaling overhead.

[0033] It can be understood that when the position of the target remains unchanged, when the first network element directly indicates the identifier of the target to the measurement device next time, the measurement device can determine the information of the target corresponding to the target according to the identifier of the target, such as the position, the distance between the target and the measurement device, the orientation of the target, etc.

[0034] Combined with the second aspect, in some possible implementation manners of the second aspect, the information of the target further includes one or more of the following: information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device.

[0035] Among them, the information indicating the position of the target can be, for example, the position coordinates of the target. The position coordinates of the target can be the absolute position coordinates or relative position coordinates of the target, and the present application does not make any limitation in this regard.

[0036] The orientation of the target can be the absolute orientation or relative orientation. The absolute orientation can be, for example, the orientation of the target relative to the measurement device. The relative orientation can be, for example, the orientation of the target (denoted as target 1) relative to another target (denoted as target 2), and the present application does not make any limitation in this regard.

[0037] The angle of the target can be the angle of the target relative to the reference direction, or rather, the included angle between the connection line between the target and the measurement device and the reference direction.

[0038] The distance between the target and the measurement device can be the absolute distance or relative distance. Among them, the absolute distance can be, for example, the distance value or distance range between the target and the measurement device. The relative distance can be, for example, the distance between the target and the measurement device relative to the reference distance. The reference distance can be, for example, the distance between the measurement device and another target.

[0039] By indicating the information of the target, the first network element helps the measurement device determine the beam direction for transmitting the reference signal, and then transmit the reference signal in this beam direction to complete the measurement of the target. In this way, even if the position of the target changes, the measurement device can know the beam direction for transmitting the reference signal to complete the measurement of the target.

[0040] Optionally, the information of the target can include one or more of the following: information indicating the identifier of the target, information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device.

[0041] That is to say, the information of the above-mentioned target may also include one or more of the following: information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measuring device, and does not include information indicating the identity of the target. In this way, the measuring device can also determine the corresponding target according to the information of the above-mentioned target.

[0042] Combined with the second aspect, in some possible implementation manners of the second aspect, the above method further includes: receiving a first message, where the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the position where the measuring device is located, the direction of the antenna panel of the measuring device, or the number of antenna elements of the measuring device.

[0043] Whether it has the ability to measure can be used by the first network element to determine whether to select this measuring device to measure the target; whether it has the ability to detect deformation can be used by the first network element to determine whether to select this measuring device to perform deformation detection; the position of the measuring device can be used by the first network element to determine which measuring device to select for measurement according to the position of the target and the position of the measuring device. The direction of the antenna panel of the measuring device can be used by the first network element to determine which measuring device to select for measurement according to the direction of the target and the direction of the antenna panel. In addition, the first network element can also determine the measuring device used to measure the target according to the number of antenna elements. For example, it can select a measuring device with a larger number of antenna elements to measure the target.

[0044] Combined with the second aspect, in some possible implementation manners of the second aspect, the above method further includes: sending a second message, where the second message is used to request configuration information of a reference signal resource, the reference signal resource is used to transmit a reference signal, and the reference signal is used to measure the above-mentioned target; receiving the configuration information.

[0047] It can be understood that the first network element performs deformation calculation on the target based on the measurement results. That is to say, the first network element can perform deformation calculation on the target based on the measurement results reported by the measurement device multiple times. In other words, the first network element can perform deformation calculation on the target according to the measurement results of the target at different times.

[0048] It can be understood that the method described in the first aspect and any possible implementation manner of the first aspect can be applied to the scenario of single - station sensing. That is, the device that sends the reference signal and the device that receives the echo signal are the same device. Among them, the echo signal is the signal reflected by the target after the reference signal reaches the target.

That is, the device that sends the reference signal and the device that receives the echo signal are different devices.

[0049] In a third aspect, the present application provides a measurement method. This method can be executed by the first measurement device, or by components (such as chips, chip systems, etc.) in the first measurement device, or by a logic module or software that can implement all or part of the functions of the first measurement device.

[0052] In the above - mentioned technical solution, the first measurement device can receive a measurement request from the first network element, and this measurement request is used to request measurement of the target. In other words, the first measurement device can determine which target to measure, providing a method for measuring a known (or specific) target. In addition, for the first network element, it is convenient to flexibly specify which target to measure.

[0056] That is to say, the information of the above-mentioned target may also include one or more of the following: information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of a reference signal, where the reference signal is used to measure the target; or, information indicating the distances between the target and the second measurement device and the first measurement device, and does not include the information indicating the identity of the target. In this way, the measurement device can also determine the corresponding target according to the information of the above-mentioned target.

[0057] In combination with the third aspect, in some possible implementation manners of the third aspect, the above method further includes: sending a first message to a first network element, where the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the position where the first measurement device is located, the direction of the antenna panel of the first measurement device, or the number of antenna elements of the first measurement device.

[0058] In combination with the third aspect, in some possible implementation manners of the third aspect, the above method further includes: sending a measurement result to the first network element, where the measurement result is obtained by measuring the target, and the measurement result includes one or more of the following: the identity of the target, time measurement information, angle measurement information, energy measurement information, or phase measurement information.

[0063] In the above technical solution, the second measurement device may report the configuration information to the first network element, facilitating the first network element to determine whether to select the second measurement device to measure the target based on the configuration information reported by the second measurement device.

[0064] Combined with the fourth aspect, in some possible implementation manners of the fourth aspect, before receiving the second message from the first network element, the above method further includes: sending a third message to the first network element, where the third message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the location of the second measurement device, the direction of the antenna panel of the second measurement device, or the number of antenna elements of the second measurement device.

[0066] It can be understood that the second measurement device may also receive a measurement request from the first network element to determine which target to measure. For example, according to the measurement, the second measurement device may determine the beam direction for sending the reference signal; the second measurement device may also not receive a measurement request from the first network element. In this case, the second measurement device may send an omnidirectional reference signal.

[0067] Combined with the fourth aspect, in some possible implementation manners of the fourth aspect, the information about the target includes information indicating the identifier of the target.

In this way, the measurement device can also determine the corresponding target according to the information of the above-mentioned target.

[0071] In a fifth aspect, the present application provides a signal transmission method, which may be executed by a network device, or by a component (such as a chip, a chip system, etc.) in the network device, or, may also be executed by a logic module or software capable of implementing all or part of the functions of the network device.

[0073] Wherein, the above-mentioned fourth message being used to request the configuration of a reference signal may be replaced by the above-mentioned fourth message being used to request the configuration information of the reference signal.

[0074] This method may be applied to a single-site sensing scenario, where the network device senses / measures the target, the network device sends a reference signal, and receives an echo signal. This method may also be applied to a two-site sensing scenario, where the network device sends a reference signal, and another network device or terminal receives the echo signal.

[0077] Exemplarily, the method includes: receiving a fourth message from a first network element, where the fourth message is used to request the configuration of the reference signal, and the fourth message includes information about the target, and the information about the target indicates the beam direction of the reference signal; sending a fifth message to the terminal, where the fifth message is used to configure the reference signal.

[0078] Wherein, the above fourth message for requesting the configuration of the reference signal can be replaced with the above fourth message for requesting the configuration information of the reference signal.

[0079] This method can be applied to a single-site sensing scenario, where the terminal senses / measures the target, that is, the terminal sends a reference signal and receives an echo signal. This method can also be applied to a two-site sensing scenario, where the terminal sends a reference signal and another network device or terminal receives the echo signal.

[0104] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0105] For the convenience of understanding the technical solutions provided in the present application, the following explanations are made first:

[0106] First, in the present application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a device, system, product, or equipment that includes a series of modules, modules, or units does not necessarily have to be limited to those modules, modules, or units clearly listed, but may include other modules, modules, or units that are not clearly listed or are inherent to these devices, systems, products, or equipment.

[0107] Second, in the present application, an indication includes an explicit indication (also known as a direct indication) and an implicit indication (also known as an indirect indication). Among them, explicitly indicating information A means including the information A; implicitly indicating information A means indicating information A through the correspondence between information A and information B and directly indicating information B. The correspondence between information A and information B can be predefined, pre-stored, pre-fired, or pre-configured; or, it can also mean indicating information A through information B and a preset rule.

[0108] Third, in the present application, information C is used for the determination of information D, which includes both the case where information D is determined only based on information C and the case where it is determined based on information C and other information. In addition, the case where information C is used for the determination of information D can also be an indirect determination. For example, the case where information D is determined based on information E, and information E is determined based on information C.

[0109] Fourth, in the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Among them, A and B can be singular or plural. The character " / " generally represents an "or" relationship between the front and rear associated objects, but does not exclude the case where it represents a "and" relationship between the front and rear associated objects. The specific meaning represented can be understood in combination with the context. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single items (items) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Among them, a, b, and c can be single or multiple.

[0110] Fifth, in this application, the use of prefix words such as "first" and "second" is only for the convenience of distinguishing and describing different things belonging to the same name category, and does not restrict the order, size, or quantity of things. For example, "the first measuring device" and "the second measuring device" are just different measuring devices, and there is no chronological, size, or priority relationship between them.

[0111] Sixth, in this application, "send" and "receive" indicate the direction of signal transmission. For example, "sending information to a network device" can be understood as the destination of the information being the network device, which can include direct transmission through the air interface, or indirect transmission through other units or modules via the air interface. "Receiving information from a terminal" can be understood as the source of the information being the terminal, which can include directly receiving from the terminal through the air interface, or indirectly receiving from the terminal through other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0112] In other words, sending and receiving can be carried out between devices. For example, between a network device and a terminal; or can be carried out within a device. For example, sending or receiving between components, modules, chips, software modules, or hardware modules within a device through a bus, trace, or interface.

[0113] Seventh, in this application, "when", "if", and "in case" all refer to the device making corresponding processing under certain objective circumstances, not limiting time, and do not require the device to have a judgment action when implemented, nor does it mean there are other limitations.

[0114] Eighth, in this application, words such as "example", "exemplarily", "for example", or "such as" are used to give examples, illustrations, or explanations. Any embodiment or design solution described as "example", "exemplarily", "for example", or "such as" in this application should not be construed as more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "example", "exemplarily", "for example", or "such as" is intended to present the relevant concepts in a specific manner.

[0115] Ninth, in this application, pre-configuration can be understood as preset, predefined, defined, pre-defined, stored, pre-stored, pre-negotiated, prefabricated, or pre-set, etc.

[0116] Tenth, the technical solution provided by this application can be applied to various communication systems, such as: Long-Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Sidelink (SL) communication system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th Generation (5G) mobile communication system or New Radio Access Technology (NR). Among them, the 5G mobile communication system can include Non-Standalone (NSA) and / or Standalone (SA). The technical solution provided by this application can also be applied to future communication systems, such as 6th Generation (6G) mobile communication system, etc. This application does not make any limitation in this regard.

[0117] Eleventh, in the present application, the measurement device may be a network device or a terminal. Among them, the network device may be any device with wireless transceiver functions. The network device includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP) in a wireless fidelity (Wi-Fi) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc. It may also be a gNB or a transmission point (TRP or TP) in a 5G (such as NR) system, or one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or may also be a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), etc. The network device may also be a wireless controller in a cloud radio access network (CRAN) scenario.

[0118] In this application, a terminal may also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal may include, but is not limited to: a mobile phone, a tablet (pad), a computer with wireless transceiver function, a virtual reality (VR) device, an augmented reality (AR) device, a mixed reality (MR) device, an extended reality (XR) device, a wireless terminal in industrial control, a vehicle-mounted device, a wireless terminal in unmanned driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wearable device, a video player, a full-system projector, etc. This application does not limit the specific form of the terminal.

[0119] Deformation detection is to obtain the changes of a specific target through long-term measurement of the target. Deformation detection is widely used in many fields, such as industrial safety, bridge / dam safety, construction, etc. Through deformation detection, potential safety problems can be discovered in time, so as to carry out maintenance and avoid safety accidents. It can be seen that how to measure a specific target in the process of deformation detection is crucial. At present, network devices or terminals can only sense an unknown object. For example, a network device or terminal does not know whether there is an object in a certain direction. Therefore, a reference signal is sent in that direction to determine whether there is an object (or target) in that direction.

[0120] In this application, a measurement method is provided, which can measure a specific target and then complete deformation detection. Exemplarily, the measurement device can receive a measurement request from a first network element, and this measurement request is used to request measurement of the target. In other words, the measurement device can determine which target to measure, and further complete the measurement of the above target according to the information of the target included in the measurement request.

[0121] Before introducing in detail the measurement method provided by this application, the communication system applicable to this application will be described in detail below.

[0122] Figure 1 It is a schematic diagram of the architecture of a communication system applicable to the measurement method provided by this application.

[0123] The communication system includes a terminal, a radio access network (RAN), and a core network. The terminal can be connected to a radio access network device wirelessly, and the radio access network device can be connected to the core network wirelessly or wiredly. The core network device and the radio access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the radio access network device can be integrated on the same physical device, or the functions of part of the core network device and part of the radio access network device can be integrated on one physical device. Terminals can be connected to each other, and radio access network devices can be connected to each other, either wiredly or wirelessly.

[0124] Exemplarily, as Figure 1 shown, taking the eNB and gNB as examples of radio access network devices, the terminal and the eNB can communicate through the LTE-Uu interface, the terminal and the gNB can communicate through the NR-Uu interface, and the eNB and the gNB can communicate through the Xn interface. Among them, the eNB and the gNB can also be referred to as TPs, etc., and the present application does not limit their names. The terminal can be, for example, a secure user plane location enabled terminal (SET).

[0125] The LMF network element is a network element (or module, component) in the NR core network for providing location functions, and the access and mobility management function (AMF) network element is a network element in the NR core network for providing access management functions. For example, the AMF network element can be used to receive a location service request for a certain terminal initiated by other network elements in the network and send the received request to the LMF network element. The LMF network element is responsible for processing the received location request and initiating relevant location processes. The enhanced serving mobile location center (E-SMLC) is a network element in the 4G core network for providing location functions, and the secure user plane location protocol (SLP) network element is a network element in the 4G core network for processing the secure user plane location protocol. The radio access network device and the first network element can communicate through the NG-C interface.

[0126] It should be understood that Figure 1It is just a schematic diagram. Other network elements may also be included in the communication system. For example, the core network may also include a SMF network element, which can be used to indicate information about the target to be measured for the terminal, such as the identification of the target, the location of the target, etc.

[0127] Before describing the measurement method provided by the present application in detail, first, the perception mode applicable to the method provided by the present application will be introduced in detail in combination with Figure 2 the following.

[0128] The method provided by the present application can be applicable to single - station perception, that is, the node that sends the reference signal and the node that receives the echo signal are deployed on the same device, such as a base station or a terminal. The method provided by the present application can also be applicable to bistatic perception, that is, the node that sends the reference signal and the node that receives the echo signal are deployed on different devices. For example, the base station sends the reference signal and the terminal receives the echo signal; or, the base station sends the reference signal and another base station receives the echo signal, etc.

[0129] Figure 2 a) in shows a single - station perception scenario. For example, base station A sends a reference signal and base station A receives the echo signal. The echo signal is the signal emitted by the target after the reference signal reaches the target, that is, the scenario where the base station performs perception.

[0130] Figure 2 b) in shows another single - station perception scenario. For example, terminal A sends a reference signal and terminal A receives the echo signal. The echo signal is the signal emitted by the target after the reference signal reaches the target, that is, the scenario where the terminal performs perception.

[0131] Figure 2 c) in shows a bistatic perception scenario. For example, base station A sends a reference signal and base station B receives the echo signal; or, base station A sends a reference signal and terminal B receives the echo signal; or, terminal A sends a reference signal and base station B receives the echo signal; or, terminal A sends a reference signal and terminal B receives the echo signal, etc. Here, they are not listed one by one.

[0132] It should be understood that the base station is an example of network equipment, and the present application does not limit the specific type of network equipment.

[0133] Next, the measurement method provided by the present application will be described in detail with reference to the accompanying drawings. It should be understood that Figure 3 in the shown embodiment, the single - station perception scenario is taken as an example, but it should not constitute any limitation to the embodiments of the present application. Among them, the measurement device can be, for example, a terminal or a base station, and the present application does not limit this.

[0134] Figure 3 is a schematic flowchart of the measurement method 300 provided by the embodiments of the present application.Figure 3 The method is described by taking the interaction between the measurement device and the first network element as an example, and it should not constitute any limitation to this application. Figure 3 The measurement device in [description] can also be replaced by components configured in the measurement device (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the measurement device. The first network element can be replaced by components configured in the first network element (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the first network element.

[0135] In step 310, the first network element sends a measurement request, which is used to request measurement of a target, and the measurement request includes information about the target. Correspondingly, the measurement device receives the measurement request from the first network element.

[0136] Among them, the above-mentioned first network element can be a network element for providing sensing / measurement / detection / localization functions. The first network element can be deployed on the access network side or the core network side, and this application does not make any limitation in this regard. The first network element can be, for example, an LMF network element or an SMF network element, or other types of network elements, and this application does not make any limitation on the specific type of the first network element.

[0137] The above-mentioned target refers to the object to be measured. The above-mentioned target can be a passive target, and a passive target refers to an object that cannot actively send signals, such as a bridge, an oil tank, etc. The above-mentioned target can also be an active target, and an active target refers to an object that can actively send signals, such as a mobile phone, a computer, etc. When the above-mentioned target is an active target, the measurement of the above-mentioned target by the measurement device does not depend on the signal actively sent by the target. In other words, the signal used to measure the above-mentioned target is not sent by the target. The above-mentioned target can be static, that is, the position of the target remains unchanged, and the above-mentioned target can also be dynamic, that is, the position of the target can change, and this application does not make any limitation in this regard.

[0138] The above-mentioned measurement device can be, for example, a terminal or a network device (such as a base station), and this application does not make any limitation on the specific form of the measurement device.

[0139] Exemplarily, the first network element sends a measurement request to the base station, which is used to request measurement of a target, and the measurement request includes information about the target. Correspondingly, the base station receives the above-mentioned measurement request, and the base station is used to measure the target.

[0140] In step 320, the measurement device measures the above-mentioned target according to the information about the target.

[0141] The above measurement of the target may specifically include: the measurement device sends a reference signal and receives an echo signal, where the echo signal is the signal reflected by the target after the reference signal reaches the target. The above reference signal is used to measure the target, or in other words, to sense / detect the target, etc. The above reference signal may be, for example, a positioning reference signal (PRS), or a sensing reference signal (SRS), etc. The type of the reference signal in this application is not limited.

[0142] As an example but not a limitation, the measurement device may periodically send a reference signal and receive an echo signal, and this reference signal can be used to measure the target. In this way, the measurement device can obtain measurement results of the target at different times, so that the first network element can perform deformation calculation on the target according to the measurement results at different times.

[0143] Optionally, the information of the above target includes information indicating the identifier of the target.

[0144] The identifier of the above target is used to identify the target, and different identifiers can be used to distinguish different targets.

[0145] Exemplarily, the identifier of the target may be the index or identifier (ID) of the target, or the name of the target. This application does not limit this.

[0146] Optionally, the information of the above target further includes one or more of the following: information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device.

[0147] Among them, the information indicating the position of the target may be, for example, the position coordinates of the target. The position coordinates of the target may be the absolute position coordinates or relative position coordinates of the target. This application does not limit this. The above relative position coordinates may be the coordinates of the target relative to the measurement device. This application does not limit this.

[0148] For example, taking a rectangular coordinate system as an example, if the absolute coordinates of the measurement device are (1, 1) and the absolute position coordinates of the target are (4, 3), then the position coordinates of the target relative to the measurement device are (3, 2). The position of the target can be indicated by the absolute coordinates (4, 3) or the relative coordinates (3, 2).

[0149] The orientation of the above-mentioned target can be an absolute orientation or a relative orientation. The absolute orientation can be, for example, the orientation of the target relative to the measurement device. For example, the above-mentioned target is 30 degrees south by east of the measurement device. The relative orientation can be, for example, the orientation of the above-mentioned target (denoted as target 1) relative to another target (denoted as target 2). This application does not make any limitations in this regard. For example, if the measurement device knows the orientation of the above-mentioned target 2 relative to itself, and the relative orientation of the above-mentioned target 1 is, for example, 30 degrees south by west of the above-mentioned target 2, then the measurement device can determine the orientation of target 1 relative to itself.

[0150] The angle of the above-mentioned target can be the angle of the target relative to the reference direction, or in other words, the included angle between the connection line between the target and the measurement device and the reference direction. Among them, the reference direction can be, for example, predefined or indicated / configured by the first network element. This application does not make any limitations in this regard. For example, the included angle between the connection line between the target and the measurement device and the reference direction can be the azimuth angle of the target relative to the measurement device (such as 50 degrees). In other words, the reference direction can be the due north direction of the measurement device.

[0151] The beam direction of the above-mentioned reference signal can be a subset of the beam directions supported by the base station. The beam direction of the above-mentioned reference signal can be related to the orientation or angle of the target. Exemplarily, the first network element can determine the beam direction of the reference signal according to the orientation or angle of the target, and indicate the beam direction of the reference signal to the measurement device. Among them, the beam direction of the reference signal and the orientation or angle of the target can be one-to-one corresponding. The beam direction can be indicated based on another reference signal, indicating that the above-mentioned reference signal is transmitted or received based on the beam of receiving another reference signal, or indicating that the above-mentioned reference signal is transmitted or received based on the beam of transmitting another reference signal.

[0152] The distance between the above-mentioned target and the measurement device can be an absolute distance or a relative distance. Among them, the absolute distance can be, for example, the distance value (such as 50 meters) or the distance range (such as 30 meters to 50 meters) between the target and the measurement device. The relative distance can be, for example, the distance between the target and the measurement device relative to the reference distance. The above-mentioned reference distance can be, for example, the distance between the measurement device and another target. For example, the distance between the measurement device and target 2 is 50 meters, and the relative distance between the measurement device and target 1 is 10 meters. Then the absolute distance between the measurement device and target 1 can be, for example, 50 + 10 = 60 meters.

[0153] It can be understood that the information of the above-mentioned target is only an example and should not constitute any limitation to this application. For example, the information of the target can also include the information indicating the reference signal resource, where the reference signal resource can correspond to the beam direction.

[0154] Optionally, the information of the above target may include one or more of the following: information indicating the identity of the target, information indicating the location of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measuring device.

[0155] That is to say, the information of the above target may also include one or more of the following: information indicating the location of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measuring device, without including the information indicating the identity of the target.

[0156] Optionally, before the measuring device receives a measurement request from the first network element, the method 300 further includes step 301: the measuring device sends a first message to the first network element, and the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the location where the measuring device is located, the direction of the antenna panel of the measuring device, or the number of antenna elements of the measuring device. Correspondingly, the first network element receives the above first message.

[0157] Whether it has the ability to measure can be used by the first network element to determine whether to select this measuring device to measure the target.

[0158] Whether it has the ability to detect deformation can be used by the first network element to determine whether to select this measuring device to perform deformation detection.

[0159] The location of the measuring device can be used by the first network element to determine which measuring device to select for measurement according to the location of the target and the location of the measuring device.

[0160] The direction of the antenna panel of the measuring device can be used by the first network element to determine which measuring device to select for measurement according to the direction of the target and the direction of the antenna panel. In addition, the first network element can also determine the measuring device used to measure the target according to the number of antenna elements. For example, a measuring device with a larger number of antenna elements can be selected to measure the target.

[0161] Among them, the above first message can be actively reported by the measuring device or requested to be reported by the first network element, and this application does not make a limitation on this.

[0162] In one example, the first network element sends a request message to the measuring device, and the request message is used to request the measuring device to report the above first message. Correspondingly, the measuring device receives the above request message and reports the above first message to the first network element.

[0163] In another example, the measuring device actively reports the first message to the first network element.

[0164] Optionally, before the measurement device receives a measurement request from the first network element, the above method 300 further includes step 302 and step 303. Among them, in step 302, the first network element sends a second message, which is used to request configuration information of a reference signal resource. The reference signal resource is used to transmit a reference signal, and the reference signal is used to measure the above target. Correspondingly, the measurement device receives the above second message. In step 303, the measurement device sends configuration information. Correspondingly, the first network element receives the above configuration information.

[0165] The above configuration information can be used to configure one or more of the following: time domain resources, frequency domain resources, or spatial domain resources, etc. Exemplarily, the above configuration information includes the period of the reference signal, one or more beam directions, or at least one time-frequency resource. Among them, the beam direction of the reference signal indicated by the first network element in the measurement request mentioned above can be a subset of the above one or more beam directions.

[0166] Optionally, the above method 300 further includes step 321: The measurement device sends a measurement result to the first network element. The measurement result is obtained by measuring the above target, and the measurement result includes one or more of the following: the identifier of the target, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Correspondingly, the first network element receives the above measurement result. The first network element can also perform deformation calculation on the target based on the measurement result.

[0167] Among them, the time measurement information includes but is not limited to: TOA, TDOA, RTT, or RSTD. The angle measurement information includes but is not limited to: AOD or AOA. The energy measurement information includes but is not limited to: RSS. The phase measurement information includes but is not limited to: the phase of the reference signal or the phase difference.

[0168] It can be understood that the first network element performs deformation calculation on the target based on the measurement result. It can be understood that the first network element can perform deformation calculation on the target based on the measurement results reported by the measurement device multiple times. In other words, the first network element can perform deformation calculation on the target according to the measurement results of the target at different times. Exemplarily, the deformation amount of the target can be obtained, for example, through the following formula: Among them, represents the change value of the phase of the echo signal, and λ represents the wavelength corresponding to the phase.

[0169] Based on the above technical solution, the measurement device can receive a measurement request from the first network element, and this measurement request is used to request the measurement of a target. In other words, the measurement device can determine which target to measure, and further complete the measurement of the above target according to the information of the target included in the measurement request, providing a method for measuring a known (or specific) target. In addition, for the first network element, it is convenient to flexibly specify which target to measure.

[0170] Figure 4 In the illustrated embodiment, the scenario of bistatic sensing is taken as an example, but it should not constitute any limitation to the embodiments of the present application. Among them, the first measurement device can be, for example, a terminal or a base station, and the second measurement device can be, for example, a terminal or a base station. The present application does not make any limitation in this regard.

[0171] Figure 4 It is a schematic flowchart of the measurement method 400 provided by the embodiments of the present application. Figure 4 This method is only described by taking the interaction among the first measurement device, the second measurement device, and the first network element as an example, and it should not constitute any limitation to the present application. Figure 4 The first measurement device in [description] can also be replaced by components configured in the first measurement device (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the first measurement device. The second measurement device can also be replaced by components configured in the second measurement device (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the second measurement device. The first network element can be replaced by components configured in the first network element (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the first network element.

[0172] In step 410, the first network element sends a measurement request to the first measurement device. This measurement request is used to request the measurement of a target, and the information of the target is included in this measurement request. Correspondingly, the first measurement device receives the above measurement request.

[0173] Among them, the first measurement device can be a device that receives an echo signal, and the echo signal is a signal reflected by the target after the reference signal arrives at the target. The first measurement device can be, for example, a terminal or a network device. The present application does not make any limitation in this regard.

[0174] For the explanations of the first network element and the target, reference can be made to step 310, which will not be elaborated here.

[0175] It can be understood that as a device for receiving echo signals, after receiving the above measurement request, the first measurement device can determine which target to measure and obtain information about the above target. The information about the above target can be used, for example, by the first measurement device to determine in which beam direction to receive echo signals.

[0176] Exemplarily, the second measurement device can periodically send a reference signal. After receiving the above measurement request, the first measurement device can receive the echo signal of the above reference signal. Among them, the second measurement device can send an omnidirectional reference signal or a reference signal in a specific beam direction. For example, the above method 400 further includes step 411: The first network element sends the above measurement request to the second measurement device, the second measurement device receives the above measurement request, and based on the information about the target, sends a reference signal. The second measurement device can determine the beam direction of the reference signal according to the information about the target in the measurement request.

[0177] Optionally, the information about the above target includes information indicating the identifier of the target.

[0178] The identifier of the above target is used to identify the target, and different identifiers can be used to distinguish different targets.

[0179] Exemplarily, the identifier of the target can be the index or ID of the target, or the name of the target. This application does not make any limitations in this regard.

[0180] Optionally, the information about the above target further includes one or more of the following: information indicating the position of the target; information indicating the azimuth or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the second measurement device and the first measurement device.

[0181] Among them, the information indicating the position of the target can be, for example, the position coordinates of the target. The position coordinates of the target can be the absolute position coordinates or relative position coordinates of the target. This application does not make any limitations in this regard. The above relative position coordinates can be, for example, the coordinates of the target relative to the second measurement device (or the first measurement device). This application does not make any limitations in this regard.

[0182] For example, taking a rectangular coordinate system as an example, if the absolute coordinates of the second measurement device are (1, 2) and the absolute position coordinates of the target are (4, 3), then the position coordinates of the target relative to the second measurement device are (3, 1). The position of the target can be indicated by the absolute coordinates (4, 3) or the relative coordinates (3, 1).

[0183] The orientation of the above-mentioned target can be an absolute orientation or a relative orientation. The absolute orientation can be, for example, the orientation of the target relative to the second measurement device (or the first measurement device). For example, the above-mentioned target is 30 degrees south by east of the second measurement device. The first measurement device can determine the orientation of the target relative to the first measurement device based on the orientation of the target and the orientation of the second measurement device. Another example is that the above-mentioned target is 30 degrees south by west of the first measurement device.

[0184] The relative orientation can be, for example, the orientation of the above-mentioned target (target 1) relative to another target (denoted as target 2), and this application does not limit it. For example, the first measurement device knows the orientation of the above-mentioned target 2 relative to itself. If the relative orientation of the above-mentioned target 1 is, for example, 30 degrees south by west of the above-mentioned target 2, then the first measurement device can determine the orientation of target 1 relative to itself.

[0185] The angle of the above-mentioned target can be the angle of the target relative to the reference direction, or in other words, the included angle between the line connecting the target and the second measurement device and the reference direction. Among them, the reference direction can be predefined, or indicated / configured by the first network element, and this application does not limit it.

[0186] Exemplarily, the reference direction is the direction where the line connecting the second measurement device and the first measurement device is located.

[0187] That is to say, the included angle between the line connecting the target and the second measurement device and the reference direction can be the included angle from the direction where the line connecting the second measurement device and the first measurement device is located as the reference direction to the target direction line in the clockwise direction.

[0188] The beam direction of the above-mentioned reference signal can be a subset of the beam directions supported by the base station. The beam direction of the above-mentioned reference signal can be related to the orientation or angle of the target. Exemplarily, the first network element can determine the beam direction of the reference signal according to the orientation or angle of the target, and indicate the beam direction of the reference signal to the measurement device. Among them, the beam direction of the reference signal and the orientation or angle of the target can be one-to-one correspondence. The beam direction can be indicated based on another reference signal, indicating that the above-mentioned reference signal is transmitted or received based on the beam of receiving another reference signal, or indicating that the above-mentioned reference signal is transmitted or received based on the beam of transmitting another reference signal.

[0189] The distance between the above-mentioned target and the second measurement device and the first measurement device can be an absolute distance or a relative distance. Among them, the absolute distance can be, for example, the distance value (such as 50 meters) or distance range (such as 30 meters to 50 meters) between the target and the second measurement device and the first measurement device. For example, the above-mentioned absolute distance = the distance between the target and the second measurement device + the distance between the target and the first measurement device.

[0190] The above relative distance can be, for example, the distance difference between the reflected path and the direct path. Here, the reflected path is the path that the reference signal reaches the first measurement device after being reflected by the target, and the direct path is the path that the reference signal directly reaches the first measurement device.

[0191] Optionally, the information of the above target may include one or more of the following: information indicating the identity of the target, information indicating the location of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the measurement device.

[0192] That is to say, the information of the above target may also include one or more of the following: information indicating the location of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the second measurement device and the first measurement device, and does not include the information indicating the identity of the target.

[0193] Optionally, before the first measurement device receives the measurement request from the first network element, the method 400 further includes step 401: sending a first message to the first network element, where the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the location where the first measurement device is located, the direction of the antenna panel of the first measurement device, or the number of antenna elements of the first measurement device. Correspondingly, the first network element receives the above first message.

[0194] Wherein, the above first message can be actively reported by the first measurement device or requested to be reported by the first network element, and this application does not make a limitation on this.

[0195] For a detailed explanation of the above first message, reference can be made to Figure 3 the explanation of the first message reported by the measurement device in, and details are not described herein again.

[0196] Optionally, the method 400 further includes step 402: The second measurement device can also report a third message to the first network element, where the third message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the location where the second measurement device is located, the direction of the antenna panel of the second measurement device, or the number of antenna elements of the second measurement device. For a detailed explanation of the above third message, reference can be made to Figure 3 the explanation of the first message reported by the measurement device in, and details are not described herein again.

[0197] Optionally, the above method 400 further includes step 403 and step 404. In step 403, a first network element sends a second message, which is used to request configuration information of reference signal resources. Correspondingly, a second measurement device receives the above second message. Step 404 is that the second measurement device sends the configuration information. Correspondingly, the first network element receives the above configuration information.

[0198] The above configuration information can be used to configure one or more of the following: time domain resources, frequency domain resources, or spatial domain resources, etc. Exemplarily, the above configuration information includes the period of the reference signal, one or more beam directions, or at least one time-frequency resource.

[0199] It can be understood that when the device sending the reference signal is a terminal (i.e., the second measurement device is a terminal), the first network element can send a second message to the network device serving the terminal to request the network device to configure the reference signal resources.

[0200] In step 420, the first measurement device measures the above target based on the information of the target.

[0201] The first measurement device measuring the above target based on the information of the target may specifically include the first measurement device receiving an echo signal and obtaining a measurement result based on the echo signal.

[0202] The second measurement device sends a reference signal in a specific beam direction or sends an omnidirectional reference signal. Correspondingly, the first measurement device receives the echo signal and obtains a measurement result based on the echo signal.

[0203] Optionally, the above method 400 further includes step 421: The first measurement device sends a measurement result to the first network element. The measurement result is obtained by measuring the above target, and the measurement result includes one or more of the following: the identifier of the target, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Correspondingly, the first network element receives the above measurement result. The first network element can also perform deformation calculation on the target based on the measurement result. For a detailed description of the measurement result, reference can be made to Figure 3 , which will not be elaborated here.

[0204] Based on the above technical solution, the first measurement device can receive a measurement request from the first network element, and the measurement request is used to request measurement of a target. In other words, the first measurement device can determine which target to measure, providing a method for measuring a known (or specific) target. That is to say, the first network element can flexibly specify which target to measure.

[0205] Figure 5 It is a schematic flowchart of a signal transmission method 500 provided by an embodiment of the present application. Figure 5The method is only described by taking the interaction between a network device and a first network element as an example, and should not constitute any limitation to this application. Figure 5 The network device in Figure 5 can also be replaced by components configured in the network device (such as chips, chip systems, processors, etc.), or, logical modules or software that can implement all or part of the functions of the network device. The first network element can be replaced by components configured in the first network element (such as chips, chip systems, processors, etc.), or, logical modules or software that can implement all or part of the functions of the first network element.

[0206] Figure 5 The method shown can be applied to a single-site sensing scenario, where the network device senses / measures a target, the network device sends a reference signal, and receives an echo signal. Figure 5 The method shown can also be applied to a bistatic sensing scenario, where the network device sends a reference signal, and another network device or terminal receives the echo signal.

[0207] In step 510, the first network element sends a fourth message, which is used to request the configuration of a reference signal, and the fourth message includes information about the target. Correspondingly, the network device receives the above fourth message. That is to say, when the first network element requests the configuration of a reference signal, it indicates the information about the target to the network device, so as to facilitate the network device to measure the target.

[0208] Among them, the information about the target can indicate the beam direction of the reference signal. The above fourth message used to request the configuration of a reference signal can also be replaced by that the above fourth message is used to request the configuration information of the reference signal.

[0209] Exemplarily, the first network element sends a fourth message to request the configuration of a reference signal, and the fourth message includes information about the target. Correspondingly, the network device receives the above fourth message and configures the reference signal, or rather, configures the reference signal resources, for example, configures the time-domain resources, frequency-domain resources, and spatial-domain resources for transmitting the reference signal. It can be understood that the network device can configure the resources of the reference signal for measuring the target according to the information about the target, and send the reference signal on the above resources to measure the target.

[0210] Optionally, the above information about the target includes information indicating the identifier of the target. For the information indicating the identifier of the target, reference can be made to Figure 3 the relevant description, which will not be elaborated here.

[0211] Optionally, the information about the above-mentioned target further includes one or more of the following: information indicating the location of the target; information indicating the orientation or angle of the target; information indicating the beam direction of the reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the network device. For a detailed explanation of the above information, reference can be made to Figure 3 , which will not be elaborated here.

[0212] In step 520, the network device sends a reference signal.

[0213] Exemplarily, the network device may send a reference signal on the configured reference signal resource.

[0214] Optionally, the above method 500 further includes: the network device sends a first message to the first network element, and the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to detect deformation, the location where the network device is located, the direction of the antenna panel of the network device, or the number of antenna elements of the network device. Correspondingly, the first network element receives the above first message.

[0215] Among them, the above first message may be actively reported by the network device or requested to be reported by the first network element, and this application does not make any limitation thereto. For a detailed explanation of the first message, reference can be made to Figure 3 , which will not be elaborated here.

[0216] It can be understood that when the above network device is both the sender of the reference signal and the receiver of the echo signal, the above method 500 further includes: the network device sends a measurement result to the first network element, and the measurement result is obtained by measuring the above target, and the measurement result includes one or more of the following: the identifier of the target, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Correspondingly, the first network element receives the above measurement result. The first network element may also perform deformation calculation on the target based on the measurement result.

[0217] Based on the above technical solution, the fourth message for requesting the configuration of the reference signal may include the information of the target, that is, the first network element indicates the information of the target to the network device while requesting the configuration of the reference signal, so as to facilitate the network device to measure the target. In addition, compared with additionally requesting to measure the target, such as sending a measurement request, it is beneficial to reduce the signaling overhead.

[0218] Figure 6 It is a schematic flowchart of the signal transmission method 600 provided by an embodiment of the present application. Figure 6 This method is only described by taking the interaction between the network device and the first network element as an example, and should not constitute any limitation to the present application. Figure 6The network device therein can also be replaced by components configured in the network device (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the network device. The first network element can be replaced by components configured in the first network element (such as chips, chip systems, processors, etc.), or logical modules or software that can implement all or part of the functions of the first network element.

[0219] Figure 6 The method shown can be applied to the scenario of single-site sensing, where the terminal senses / measures the target, that is, the terminal sends a reference signal and receives an echo signal. Figure 6 The method shown can also be applied to the scenario of bistatic sensing, where the terminal sends a reference signal and another network device or terminal receives the echo signal.

[0220] In step 610, the first network element sends a fourth message, which is used to request the configuration of a reference signal, and the fourth message includes information about the target. Correspondingly, the network device receives the above fourth message. That is, when the first network element requests the configuration of a reference signal, it indicates the information about the target to the network device so that the network device can measure the target.

[0221] Among them, the information about the target can indicate the beam direction of the reference signal. The above fourth message used to request the configuration of a reference signal can also be replaced by the above fourth message used to request the configuration information of the reference signal.

[0222] Exemplarily, the first network element sends a fourth message to request the configuration of a reference signal, and the fourth message includes information about the target. Correspondingly, the network device receives the above fourth message and configures the reference signal, or rather, configures the reference signal resources. For example, it configures the time-domain resources, frequency-domain resources, and spatial-domain resources for transmitting the reference signal. It can be understood that the network device can configure the resources of the reference signal for measuring the target according to the information about the target, and send the configuration information of the resources of the above reference signal to the terminal so that the terminal can measure the target based on the above configuration. Specifically, the terminal can send a reference signal on the configured resources to complete the measurement of the target.

[0223] Optionally, the above information about the target includes information indicating the identifier of the target. For the information indicating the identifier of the target, reference can be made to Figure 3 the relevant description, which will not be elaborated here.

[0224] Optionally, the information of the above target further includes one or more of the following: information indicating the position of the target; information indicating the orientation or angle of the target; information indicating the beam direction of a reference signal, where the reference signal is used to measure the target; or, information indicating the distance between the target and the network device. For a detailed explanation of the above information, reference can be made to Figure 3 , which will not be elaborated here.

[0225] In step 620, the network device sends a fifth message to the terminal, and the fifth message is used to configure a reference signal. Correspondingly, the terminal receives the above fifth message.

[0226] By way of example and not limitation, the above fifth message may include time domain resources, frequency domain resources, or spatial domain resources, etc. for transmitting the reference signal. Exemplarily, the above fifth message includes the period of the reference signal, one or more beam directions, or at least one time-frequency resource.

[0227] Exemplarily, the network device sends a fifth message to the terminal. After receiving the fifth message, the terminal may measure the target based on the fifth message. For example, the terminal sends a reference signal and receives an echo signal based on the fifth message. Another example is that the terminal sends a reference signal based on the fifth message, and another terminal or the network device receives the echo signal. It can be understood that the receiver of the echo signal may also report a measurement result to the first network element, and the measurement result includes one or more of the following: the identifier of the target, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Correspondingly, the first network element receives the above measurement result. The first network element may also perform deformation calculation on the target based on the measurement result.

[0228] Optionally, the above method 600 further includes: the network device sends a first message to the first network element, and the first message indicates one or more of the following: whether it has the ability to measure, whether it has the ability to perform deformation detection, the position where the network device is located, the direction of the antenna panel of the network device, or the number of antenna elements of the network device. Correspondingly, the first network element receives the above first message.

[0229] Among them, the above first message may be actively reported by the network device or requested to be reported by the first network element, and this application does not make a limitation in this regard. For a detailed explanation of the first message, reference can be made to Figure 3 , which will not be elaborated here.

[0230] Based on the above technical solution, the fourth message for requesting the configuration of the reference signal may include the information of the target, that is, the first network element indicates the information of the target to the network device while requesting the configuration of the reference signal. Compared with additionally requesting to measure the target, such as sending a measurement request, it is beneficial to reduce signaling overhead.
