Description

A measurement method and related device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 12, 2024, with application number 202410054120.3 and application name “A measurement method and related device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a measurement method and related devices. Background Art

[0003] Deformation detection is widely used in numerous fields, such as industrial safety, bridge / dam safety, and construction. It helps promptly identify potential safety issues, enabling maintenance and preventing accidents. Deformation detection involves measuring a specific target over time to detect changes. Therefore, determining the target's specific measurement is crucial in the deformation detection process.

[0004] Therefore, there is an urgent need to provide a method that can complete the measurement of specific targets. Summary of the Invention

[0005] The present application provides a measurement method and related devices to complete the measurement of a specific target.

[0006] On the first aspect, the present application provides a measurement method, which can be performed by a measuring device, or by a component in the measuring device (such as a chip, a chip system, etc.), or by a logic module or software that can realize all or part of the functions of the measuring device. The present application does not limit this.

[0007] Exemplarily, the method includes: receiving a measurement request from a first network element, the measurement request being used to request measurement of a target, the measurement request including information of the target; and measuring the target according to the target information.

[0008] In this application, the first network element may be a network element for providing perception / measurement / detection / positioning functions. The first network element may be deployed on the access network side or on the core network side, and this application does not limit this. The first network element may be, for example, a location management function (LMF) network element or a sensing management function (SMF) network element, and this application does not limit the specific type of the first network element.

[0009] In this application, the target can be a passive target, which refers to an object that cannot actively transmit signals, such as a bridge or a gasoline tank. Alternatively, the target can be an active target, which refers to an object that can actively transmit signals, such as a mobile phone or a computer. When the target is an active target, the measurement device's measurement of the target does not rely on the target's active transmission of signals. In other words, the signal used to measure the target is not transmitted by the target.

[0010] In the above technical solution, the measurement device can receive a measurement request from a first network element, requesting measurement of a target. In other words, the measurement device can determine which target to measure and, based on the target information included in the measurement request, complete the measurement of the target. This provides a method for measuring a known (or specific) target. Furthermore, the first network element can flexibly specify which target to measure.

[0011] In combination with the first aspect, in some possible implementations of the first aspect, the target information includes information indicating an identifier of the target.

[0012] The target identifier is used to identify the target, and different identifiers can be used to distinguish different targets. On the one hand, the target identifier can be used to distinguish measurement results corresponding to different targets when the measurement device reports the measurement results to the first network element. On the other hand, if the target's location has not changed, the first network element can directly indicate the target identifier to the measurement device the next time, without indicating specific target information such as the target's location or the distance between the target and the measurement device, thereby reducing signaling overhead.

[0013] It can be understood that when the position of the target has not changed, the next time the first network element directly indicates the target identification to the measuring device, the measuring device can determine the target information corresponding to the target based on the above target identification, such as the position of the target, the distance between the target and the measuring device, the orientation of the target, etc.

[0014] In combination with the first aspect, in some possible implementations of the first aspect, the information of the above-mentioned target also 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, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0015] The information indicating the position of the target may be, for example, the position coordinates of the target, wherein the position coordinates of the target may be the absolute position coordinates or relative position coordinates of the target, which is not limited in this application.

[0016] 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 measuring device. The relative orientation can be, for example, the orientation of the above-mentioned target (recorded as target 1) relative to another target (recorded as target 2). This application does not limit this.

[0017] The angle of the target may be the angle of the target relative to the reference direction, or in other words, the angle between the line between the target and the measuring device and the reference direction.

[0018] The distance between the target and the measuring device can be an absolute distance or a relative distance. An absolute distance can be, for example, a distance value or a distance range between the target and the measuring device. A relative distance can be, for example, the distance between the target and the measuring device relative to a reference distance, such as the distance between the measuring device and another target.

[0019] By indicating the information of the above-mentioned target, the first network element helps the measuring device determine the beam direction of the transmitted reference signal, and then sends the reference signal in the beam direction to complete the measurement of the target. In this way, even if the position of the above-mentioned target changes, the measuring device can also know the beam direction of the sent reference signal to complete the measurement of the target.

[0020] Optionally, the information of the above-mentioned target may include one or more of the following: information indicating the identification 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 a reference signal, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0021] That is, the target information may include one or more of the following: information indicating the target's location; information indicating the target's orientation or angle; information indicating the beam direction of a reference signal used to measure the target; or information indicating the distance between the target and the measurement device, rather than information indicating the target's identifier. In this way, the measurement device can also determine the corresponding target based on the target information.

[0022] In combination with the first aspect, in some possible implementations of the first aspect, the above method also includes: sending a first message to the first network element, the first message indicating 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 measuring device, the direction of the antenna panel of the measuring device, or the number of antenna arrays of the measuring device.

[0023] The first message may be actively reported by the measurement device or requested to be reported by the first network element, which is not limited in this application.

[0024] Whether a device has measurement capability can be used by the first network element to determine whether to select the measurement device for measuring the target. Whether a device has deformation detection capability can be used by the first network element to determine whether to select the measurement device for deformation detection. The location of the measurement device can be used by the first network element to determine which measurement device to select for measurement based on the location of the target and the location of the measurement device. The orientation 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 orientation of the target and the orientation of the antenna panel. In addition, the first network element can also determine the measurement device to use for measuring the target based on the number of antenna elements. For example, a measurement device with a larger number of antenna elements can be selected to measure the target.

[0025] In combination with the first aspect, in some possible implementations of the first aspect, the above method also includes: receiving a second message from the first network element, 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 configuration information to the first network element.

[0026] The configuration information can be used to configure one or more of the following: time domain resources, frequency domain resources, or spatial domain resources. Exemplarily, the configuration information includes a reference signal period, one or more beam directions, or at least one time-frequency resource. The beam direction indicated by the first network element for transmitting the reference signal can be a subset of the one or more beam directions. That is, the first network element can select a beam direction for measuring the target from one or more beam directions reported by the measurement device and indicate it to the measurement device.

[0027] In combination with the first aspect, in some possible implementations of the first aspect, the above method also 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: target identification, time measurement information, angle measurement information, energy measurement information or phase measurement information.

[0028] Among them, 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). Angle measurement information includes but is not limited to: angle of departure (AOD) or angle of arrival (AOA). Energy measurement information includes but is not limited to: received signal strength (RSS). Phase measurement information includes but is not limited to: reference signal phase or phase difference.

[0029] On the second aspect, the present application provides a measurement method, which can be executed by a first network element, or by a component configured in the first network element (such as a chip, a chip system, etc.), or can also be implemented by a logic module or software that can implement all or part of the functions of the first network element. The present application does not limit this.

[0030] Exemplarily, the method includes: generating a measurement request, the measurement request being used to request measurement of a target, the measurement request including information of the target; and sending the measurement request to a measuring device.

[0031] 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, the first network element can flexibly specify which target to measure.

[0032] In combination with the second aspect, in some possible implementations of the second aspect, the target information includes information indicating an identifier of the target.

[0033] The target identifier is used to identify the target, and different identifiers can be used to distinguish different targets. On the one hand, the target identifier can be used to distinguish measurement results corresponding to different targets when the measurement device reports the measurement results to the first network element. On the other hand, if the target's location has not changed, the first network element can directly indicate the target identifier to the measurement device the next time, without indicating specific information about the target, such as its location or the distance between the target and the measurement device, thereby reducing signaling overhead.

[0034] It can be understood that when the position of the target has not changed, the next time the first network element directly indicates the target identification to the measuring device, the measuring device can determine the target information corresponding to the target based on the above target identification, such as the position, the distance between the target and the measuring device, the orientation of the target, etc.

[0035] In combination with the second aspect, in some possible implementations of the second aspect, the information of the above-mentioned target also 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, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0036] The information indicating the position of the target may be, for example, the position coordinates of the target, wherein the position coordinates of the target may be the absolute position coordinates or relative position coordinates of the target, which is not limited in this application.

[0037] 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 measuring device. The relative orientation can be, for example, the orientation of the above-mentioned target (recorded as target 1) relative to another target (recorded as target 2). This application does not limit this.

[0038] The angle of the target may be the angle of the target relative to the reference direction, or in other words, the angle between the line between the target and the measuring device and the reference direction.

[0039] The distance between the target and the measuring device can be an absolute distance or a relative distance. An absolute distance can be, for example, a distance value or a distance range between the target and the measuring device. A relative distance can be, for example, the distance between the target and the measuring device relative to a reference distance, such as the distance between the measuring device and another target.

[0040] By indicating the information of the above-mentioned target, the first network element helps the measuring device determine the beam direction of the transmitted reference signal, and then sends the reference signal in the beam direction to complete the measurement of the target. In this way, even if the position of the above-mentioned target changes, the measuring device can also know the beam direction of the sent reference signal to complete the measurement of the target.

[0041] Optionally, the information of the above-mentioned target may include one or more of the following: information indicating the identification 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 a reference signal, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0042] That is, the target information may include one or more of the following: information indicating the target's location; information indicating the target's orientation or angle; information indicating the beam direction of a reference signal used to measure the target; or information indicating the distance between the target and the measurement device, rather than information indicating the target's identifier. In this way, the measurement device can also determine the corresponding target based on the target information.

[0043] In combination with the second aspect, in some possible implementations of the second aspect, the above method also includes: receiving a first message, which 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 measuring device, the direction of the antenna panel of the measuring device, or the number of antenna arrays of the measuring device.

[0044] Whether a device has measurement capability can be used by the first network element to determine whether to select the measurement device for measuring the target. Whether a device has deformation detection capability can be used by the first network element to determine whether to select the measurement device for deformation detection. The location of the measurement device can be used by the first network element to determine which measurement device to select for measurement based on the location of the target and the location of the measurement device. The orientation 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 orientation of the target and the orientation of the antenna panel. In addition, the first network element can also determine the measurement device to use for measuring the target based on the number of antenna elements.

The methods described in the third to fourth aspects and any possible implementation of the third to fourth aspects below can be applied to a dual-station sensing scenario, that is, the device sending the reference signal and the device receiving the echo signal are different devices.

[0067] It can be understood that the second measurement device can also receive a measurement request from the first network element to determine which target to measure. For example, based on the measurement, the second measurement device can determine the beam direction for sending the reference signal; the second measurement device may not receive a measurement request from the first network element. In this case, the second measurement device can send an omnidirectional reference signal.

[0068] In combination with the fourth aspect, in some possible implementations of the fourth aspect, the target information includes information indicating an identifier of the target.

[0105] The technical solution in this application will be described below with reference to the accompanying drawings.

[0106] To facilitate understanding of the technical solution provided by this application, the following points are first explained:

[0107] First, in this application, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a device, system, product or apparatus comprising a series of modules, modules or units is not necessarily limited to those modules, modules or units explicitly listed, but may include other modules, modules or units that are not explicitly listed or are inherent to these devices, systems, products or apparatuses.

[0108] Second, in this application, indications include explicit indications (also called direct indications) and implicit indications (also called indirect indications). Specifically, explicit indication information A refers to including information A; implicit indication information A refers to 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-burned, or pre-configured; or, it can also refer to indicating information A through information B and preset rules.

[0109] Third, in this application, information C is used to determine information D, which includes both information D being determined solely based on information C and information D being determined based on information C and other information. Furthermore, information C can also be used to determine information D indirectly, for example, when information D is determined based on information E, and information E is determined based on information C.

[0110] Fourth, in this application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship, but it does not exclude the situation where it indicates that the previous and next associated objects are in an "and" relationship. The specific meaning can be understood in conjunction with the context. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a and b and c. Where a, b, c can be single or multiple.

[0111] Fifth, in this application, prefixes such as "first" and "second" are used solely to distinguish between different items belonging to the same category and do not constrain the order, size, or quantity of the items. For example, "first measuring device" and "second measuring device" are simply different measuring devices; there is no temporal, size, or priority relationship between the two.

[0112] Sixth, in this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to a network device" can be understood as the destination end of the information being the network device, which can include direct sending through the air interface, and also includes indirect sending through the air interface by other units or modules. "Receiving information from a terminal" can be understood as the source end of the information being the terminal, which can include direct receiving from the terminal through the air interface, and also includes indirect receiving from the terminal through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0113] In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal; or it can be performed within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, wiring or interface.

[0114] Seventh, in this application, "when", "if" and "if" all mean that the device will take corresponding actions under certain objective circumstances. It does not limit the time, nor does it require that the device must make a judgment when it is implemented, nor does it mean that there are other limitations.

[0115] Eighth, in this application, words such as "example," "exemplarily," "for example," or "such as" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "example," "exemplarily," "for example," or "such as" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "example," "exemplarily," "for example," or "such as" is intended to present the relevant concepts in a concrete manner.

[0116] Ninth, in this application, pre-configuration can be understood as preset, pre-defined, defined, pre-defined, stored, pre-stored, pre-negotiated, pre-made, or preset, etc.

[0117] Tenth, the technical solutions provided in 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), world-wide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) mobile communication system or new radio access technology (NR). Among them, the 5G mobile communication system may include non-standalone (NSA) and / or standalone (SA). The technical solutions provided in this application can also be applied to future communication systems, such as sixth generation (6G) mobile communication systems. This application is not limited to this.

[0118] Eleventh, in this application, the measuring device may be a network device or a terminal, wherein the network device may be any device with wireless transceiver function. The network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved Node B, or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (Wi-Fi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a 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 of antenna panels (including multiple antenna panels) of a base station in a 5G system, or it 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.

[0119] In this application, a terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals may include, but are not limited to: mobile phones, tablet computers, computers with wireless transceiver functions, virtual reality (VR) devices, augmented reality (AR) devices, mixed reality (MR) devices, extended reality (XR) devices, wireless terminals in industrial control, vehicle-mounted devices, wireless terminals in unmanned driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable devices, video players, full-range projectors, etc. This application does not limit the specific form of the terminal.

[0120] Deformation detection is the process of measuring a specific target over a long period of time to detect changes in the target. Deformation detection is widely used in many fields, such as industrial safety, bridge / dam safety, construction, etc. Through deformation detection, potential safety issues can be discovered in a timely manner, so that maintenance can be carried out to avoid safety accidents. It can be seen that how to measure a specific target is crucial in the deformation detection process. At present, network equipment or terminals can only perceive an unknown object. For example, the network equipment 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.

[0121] In the present application, a measurement method is provided, which can measure a specific target and thus complete deformation detection. Exemplarily, a measuring device can receive a measurement request from a first network element, and the measurement request is used to request measurement of the target. In other words, the measuring device can determine which target to measure, and further complete the measurement of the above target based on the target information included in the measurement request.

[0122] Before describing the measurement method provided by the present application in detail, the communication system to which the present application is applicable is first described in detail below.

[0123] FIG1 is a schematic diagram of the architecture of a communication system applicable to the measurement method provided in this application.

[0124] The communication system includes a terminal, a radio access network (RAN), and a core network. The terminal can be connected to the radio access network equipment wirelessly, and the radio access network equipment can be connected to the core network wirelessly or by wired means. The core network equipment and the radio access network equipment can be independent, distinct physical devices, or the functions of the core network equipment and the logical functions of the radio access network equipment can be integrated into the same physical device, or a single physical device can integrate some of the functions of the core network equipment and some of the functions of the radio access network equipment. Terminals and radio access network equipment can be connected to each other by wired or wireless means.

[0125] For example, as shown in Figure 1, the radio access network equipment takes eNB and gNB as an example. The terminal and eNB can communicate through the LTE-Uu interface, the terminal and gNB can communicate through the NR-Uu interface, and the eNB and gNB can communicate through the Xn interface. Among them, eNB and gNB can also be referred to as TP, etc., and this application does not limit their names. The terminal can be, for example, a secure user plane location enabled terminal (SET).

[0126] The LMF network element is a network element (or module, component) in the NR core network that is used to provide positioning functions, and the access and mobility management function (AMF) network element is a network element in the NR core network that is used to provide access management functions. For example, the AMF network element can be used to receive positioning service requests regarding a certain terminal initiated by other network elements in the network, and send the received requests to the LMF network element. The LMF network element is responsible for processing the received positioning requests and initiating related positioning processes. The enhanced serving mobile location center (E-SMLC) is a network element in the 4G core network that is used to provide positioning functions, and the secure user plane location protocol (SLP) network element is a network element in the 4G core network that is used to process the secure user plane location protocol. The access network device and the first network element can communicate through the NG-C interface.

[0127] It should be understood that Figure 1 is only a schematic diagram, and the communication system may also include other network elements. For example, the core network may also include an SMF network element, which can be used to indicate to the terminal the information of the target to be measured, such as the target's identification, the target's location, etc.

[0128] Before describing in detail the measurement method provided by the present application, the sensing mode applicable to the method provided by the present application will be described in detail with reference to FIG2 .

[0129] The method provided in this application can be applied to single-station sensing, that is, the node sending the reference signal and the node receiving the echo signal are deployed on the same device, such as a base station or a terminal. The method provided in this application can also be applied to dual-station sensing, that is, the node sending the reference signal and the node receiving the echo signal are deployed on different devices, for example, a base station sends the reference signal and a terminal receives the echo signal; for another example, a base station sends the reference signal and another base station receives the echo signal, etc.

[0130] Figure 2 (a) shows a single-station perception scenario, for example, base station A sends a reference signal, and base station A receives an echo signal, which is a signal transmitted by the target after the reference signal reaches the target, that is, a scenario where the base station performs perception.

[0131] b) in FIG2 shows another single-station perception scenario, for example, terminal A sends a reference signal, and terminal A receives an echo signal, which is a signal transmitted by the target after the reference signal reaches the target, that is, a scenario in which the terminal performs perception.

[0132] c) in Figure 2 shows a dual-station perception scenario, for example, base station A sends a reference signal and base station B receives an echo signal; for another example, base station A sends a reference signal and terminal B receives an echo signal; for another example, terminal A sends a reference signal and base station B receives an echo signal; for another example, terminal A sends a reference signal and terminal B receives an echo signal, and so on. They are not listed one by one here.

[0133] It should be understood that a base station is an example of a network device, and this application does not limit the specific type of the network device.

[0134] The measurement method provided by this application will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiment shown in FIG3 takes the scenario of single-station perception as an example, but should not constitute any limitation on the embodiment of this application. The measurement device can be, for example, a terminal or a base station, and this application does not limit this.

[0135] Figure 3 is a schematic flow chart of a measurement method 300 provided in an embodiment of the present application. Figure 3 only describes the method by taking the interaction between the measuring device and the first network element as an example, and should not constitute any limitation to the present application. The measuring device in Figure 3 can also be replaced by a component configured in the measuring device (such as a chip, a chip system, a processor, etc.), or a logic module or software that can implement all or part of the functions of the measuring device. The first network element can be replaced by a component configured in the first network element (such as a chip, a chip system, a processor, etc.), or a logic module or software that can implement all or part of the functions of the first network element.

[0136] In step 310, the first network element sends a measurement request, where the measurement request is used to request measurement of a target, and the measurement request includes information about the target. Accordingly, the measurement device receives the measurement request from the first network element.

[0137] The first network element may be a network element for providing perception / measurement / detection / positioning functions. The first network element may be deployed on the access network side or on the core network side, and this application does not limit this. The first network element may be, for example, an LMF network element or an SMF network element, or other types of network elements. This application does not limit the specific type of the first network element.

[0138] The above-mentioned target refers to the object to be measured. The above-mentioned target can be a passive target, which 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, which 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 measuring 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 does not change, or the above-mentioned target can be dynamic, that is, the position of the target can change, and this application does not limit this.

[0139] The above-mentioned measuring device may be, for example, a terminal or a network device (such as a base station). This application does not limit the specific form of the measuring device.

[0140] Exemplarily, the first network element sends a measurement request to the base station, where the measurement request is used to request measurement of a target, and the measurement request includes information of the target. Accordingly, the base station receives the measurement request, and the base station is used to measure the target.

[0141] In step 320, the measuring device measures the target according to the target information.

[0142] The above-mentioned measurement of the target may specifically include: the measuring device sends a reference signal and receives an echo signal, wherein the echo signal is a signal reflected by the target after the reference signal reaches the target. The above-mentioned reference signal is used to measure the target, or in other words, to sense / detect the target. The above-mentioned reference signal can be, for example, a positioning reference signal (PRS) or a sensing reference signal (SRS). The type of reference signal in this application is not limited.

[0143] As an example and not a limitation, the measuring device can periodically send a reference signal and receive an echo signal, and the reference signal can be used to measure the target. In this way, the measuring device can obtain measurement results of the target at different times, so that the first network element can calculate the deformation of the target based on the measurement results at different times.

[0144] Optionally, the target information includes information indicating an identifier of the target.

[0145] The above target identifiers are used to identify the targets, and different identifiers can be used to distinguish different targets.

[0146] Exemplarily, the identifier of the target may be an index or identifier (ID) of the target, or may be the name of the target, which is not limited in this application.

[0147] Optionally, the target information also 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, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0148] The information indicating the position of the target may be, for example, the position coordinates of the target, wherein the position coordinates of the target may be absolute position coordinates or relative position coordinates of the target, which is not limited in this application. The relative position coordinates may be the coordinates of the target relative to the measuring device, which is not limited in this application.

[0149] For example, taking the rectangular coordinate system as an example, the absolute coordinates of the measuring 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 measuring device are (3, 2). The position of the target can be indicated by the absolute coordinates (4, 3) or by the relative coordinates (3, 2).

[0150] The orientation of the target can be an absolute orientation or a relative orientation. An absolute orientation can be, for example, the orientation of the target relative to the measurement device, e.g., the target is 30 degrees east-southeast of the measurement device. A relative orientation can be, for example, the orientation of the target (denoted as target 1) relative to another target (denoted as target 2), although this application does not limit this. For example, if the measurement device knows the orientation of target 2 relative to itself, and the relative orientation of target 1 is, for example, 30 degrees west-southwest of target 2, the measurement device can determine the orientation of target 1 relative to itself.

[0151] The angle of the target may be the angle of the target relative to a reference direction, or in other words, the angle between the line connecting the target and the measuring device and the reference direction. The reference direction may be, for example, predefined or indicated / configured by the first network element, and this application does not limit this. For example, the angle between the line connecting the target and the measuring device and the reference direction may be the azimuth of the target relative to the measuring device (e.g., 50 degrees). In other words, the reference direction may be the true north direction of the measuring device.

[0152] The beam direction of the reference signal may be a subset of the beam directions supported by the base station. The beam direction of the reference signal may be related to the azimuth or angle of the target. For example, the first network element may determine the beam direction of the reference signal based on the azimuth or angle of the target, and indicate the beam direction of the reference signal to the measurement device. The beam direction of the reference signal and the azimuth or angle of the target may be in one-to-one correspondence. The beam direction may be indicated based on another reference signal, indicating that the reference signal is sent or received based on the beam receiving the other reference signal, or indicating that the reference signal is sent or received based on the beam sending the other reference signal.

[0153] The distance between the target and the measuring device can be an absolute distance or a relative distance. The absolute distance can be, for example, a distance value (e.g., 50 meters) or a distance range (e.g., 30 to 50 meters) between the target and the measuring device. The relative distance can be, for example, the distance between the target and the measuring device relative to a reference distance, which can be, for example, the distance between the measuring device and another target. For example, if the distance between the measuring device and target 2 is 50 meters, and the relative distance between the measuring device and target 1 is 10 meters, then the absolute distance between the measuring device and target 1 can be, for example, 50 + 10 = 60 meters.

[0154] It is understood that the above target information is only an example and should not constitute any limitation to the present application. For example, the target information may also include information indicating reference signal resources, wherein the reference signal resources may correspond to the beam direction.

[0155] Optionally, the information of the above-mentioned target may include one or more of the following: information indicating the identification 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 a reference signal, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0156] 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 a reference signal, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device, but not including information indicating the identification of the target.

[0157] Optionally, before the measuring device receives the 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, where the first message indicates one or more of the following: whether the measuring device has measurement capability, whether the measuring device has deformation detection capability, the location of the measuring device, the direction of the antenna panel of the measuring device, or the number of antenna elements of the measuring device. Accordingly, the first network element receives the first message.

[0158] Whether the measurement capability is available can be used by the first network element to determine whether to select the measurement device to measure the target.

[0159] Whether the measurement device has the capability of deformation detection can be used by the first network element to determine whether to select the measurement device to perform deformation detection.

[0160] 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.

[0161] The orientation 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 based on the orientation of the target and the orientation of the antenna panel. Furthermore, the first network element can also determine the measuring device to use for measuring the target based on the number of antenna elements. For example, a measuring device with a larger number of antenna elements can be selected to measure the target.

[0162] The first message may be actively reported by the measurement device or requested to be reported by the first network element, which is not limited in this application.

[0163] In one example, the first network element sends a request message to the measurement device, where the request message is used to request the measurement device to report the first message. Correspondingly, the measurement device receives the request message and reports the first message to the first network element.

[0164] In another example, the measuring device proactively reports the first message to the first network element.

[0165] Optionally, before the measurement device receives the measurement request from the first network element, the method 300 further includes steps 302 and 303. Step 302 involves the first network element sending a second message requesting configuration information for reference signal resources used to transmit reference signals used to measure the target. Accordingly, the measurement device receives the second message. Step 303 involves the measurement device sending configuration information. Accordingly, the first network element receives the configuration information.

[0166] The configuration information may be used to configure one or more of the following: time domain resources, frequency domain resources, or spatial domain resources. For example, the configuration information includes a reference signal period, one or more beam directions, or at least one time-frequency resource. The reference signal beam direction indicated by the first network element in the measurement request may be a subset of the one or more beam directions.

[0167] Optionally, the method 300 further includes step 321: the measuring device sends a measurement result to the first network element. The measurement result is obtained by measuring the target, and the measurement result includes one or more of the following: a target identifier, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Accordingly, the first network element receives the measurement result. The first network element may also perform deformation calculation on the target based on the measurement result.

[0168] Time measurement information includes, but is not limited to, time of arrival (TOA), time-delayed arrival (TDOA), real-time timing (RTT), or time-delayed arrival (RSTD). Angle measurement information includes, but is not limited to, angle of arrival (AOD) or angle of arrival (AOA). Energy measurement information includes, but is not limited to, relative speed (RSS). Phase measurement information includes, but is not limited to, the phase or phase difference of a reference signal.

[0169] It can be understood that the first network element calculates the deformation of the target based on the measurement results. It can be understood that the first network element can calculate the deformation of the target based on the measurement results reported by the measurement device multiple times. In other words, the first network element can calculate the deformation of the target based on the measurement results of the target at different times. Exemplarily, the deformation amount of the target can be obtained by the following formula: in, It represents the change in the phase of the echo signal, and λ represents the wavelength corresponding to the phase.

[0170] Based on the above technical solution, a measurement device can receive a measurement request from a first network element, requesting measurement of a target. In other words, the measurement device can determine which target to measure and, based on the target information included in the measurement request, complete the measurement of the target. This provides a method for measuring a known (or specific) target. Furthermore, the first network element can flexibly specify which target to measure.

[0171] The embodiment shown in Figure 4 takes the dual-station perception scenario as an example, but it should not constitute any limitation to the embodiments of the present application. 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. This application does not limit this.

[0172] Figure 4 is a schematic flow chart of a measurement method 400 provided in an embodiment of the present application. Figure 4 only describes the method by taking the interaction between the first measurement device, the second measurement device and the first network element as an example, and should not constitute any limitation to the present application. The first measurement device in Figure 4 can also be replaced by a component (such as a chip, a chip system, a processor, etc.) configured in the first measurement device, or a logic module 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 a component (such as a chip, a chip system, a processor, etc.) configured in the second measurement device, or a logic module or software that can implement all or part of the functions of the second measurement device. The first network element can be replaced by a component (such as a chip, a chip system, a processor, etc.) configured in the first network element, or a logic module or software that can implement all or part of the functions of the first network element.

[0173] In step 410, the first network element sends a measurement request to a first measurement device, where the measurement request is used to request measurement of a target and includes target information. Accordingly, the first measurement device receives the measurement request.

[0174] The first measuring device may be a device that receives an echo signal, which is a signal reflected by the target after the reference signal reaches the target. The first measuring device may be, for example, a terminal or a network device, which is not limited in this application.

[0175] For explanations about the first network element and the target, please refer to step 310 and will not be repeated here.

[0176] It can be understood that the first measuring device, as a device for receiving echo signals, can determine which target to measure and obtain information about the target after receiving the above measurement request. The information about the target can be used by the first measuring device to determine in which beam direction to receive the echo signal.

[0177] Exemplarily, the second measurement device may periodically transmit a reference signal, and after receiving the measurement request, the first measurement device may receive an echo signal of the reference signal. The second measurement device may transmit an omnidirectional reference signal or a reference signal in a specific beam direction. For example, the method 400 further includes step 411: the first network element transmits the measurement request to the second measurement device, the second measurement device receives the measurement request, and transmits a reference signal based on target information. The second measurement device may determine the reference signal's beam direction based on the target information in the measurement request.

[0178] Optionally, the target information includes information indicating an identifier of the target.

[0179] The above target identifier is used to identify the target, and different identifiers can be used to distinguish different targets.

[0180] Exemplarily, the identifier of the target may be the index or ID of the target, or the name of the target, which is not limited in this application.

[0181] Optionally, the target information also 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, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the second measuring device and the first measuring device.

[0182] The information indicating the position of the target may be, for example, the target's position coordinates, where the target's position coordinates may be absolute position coordinates or relative position coordinates, which are not limited in this application. The relative position coordinates may be, for example, the coordinates of the target relative to the second measurement device (or the first measurement device), which are not limited in this application.

[0183] For example, taking a rectangular coordinate system as an example, the absolute coordinates of the second measuring 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 measuring device are (3, 1). The position of the target can be indicated by the absolute coordinates (4, 3) or by the relative coordinates (3, 1).

[0184] The target's orientation can be an absolute orientation or a relative orientation. For example, the absolute orientation can be the orientation of the target relative to the second measurement device (or the first measurement device). For example, the target is 30 degrees east-southeast of the second measurement device. The first measurement device can determine the target's orientation relative to the first measurement device based on the orientation of the target and the orientation of the second measurement device. For another example, the target is 30 degrees west-southwest of the first measurement device.

[0185] The relative orientation can be, for example, the orientation of the target (target 1) relative to another target (referred to as target 2), which is not limited in this application. For example, if the first measurement device knows the orientation of target 2 relative to itself, and the relative orientation of target 1 is, for example, 30 degrees west-southwest of target 2, the first measurement device can determine the orientation of target 1 relative to itself.

[0186] The target angle may be the angle of the target relative to a reference direction, or in other words, the angle between a line connecting the target and the second measurement device and the reference direction. The reference direction may be, for example, predefined or indicated / configured by the first network element, and this application does not limit this.

[0187] Exemplarily, the reference direction is the direction of the line connecting the second measuring device and the first measuring device.

[0188] That is, the angle between the line connecting the target and the second measuring device and the reference direction can be the angle between the direction of the line connecting the second measuring device and the first measuring device and the direction of the target direction in a clockwise direction.

[0189] The beam direction of the reference signal may be a subset of the beam directions supported by the base station. The beam direction of the reference signal may be related to the azimuth or angle of the target. For example, the first network element may determine the beam direction of the reference signal based on the azimuth or angle of the target, and indicate the beam direction of the reference signal to the measurement device. The beam direction of the reference signal and the azimuth or angle of the target may be in one-to-one correspondence. The beam direction may be indicated based on another reference signal, indicating that the reference signal is sent or received based on the beam receiving the other reference signal, or indicating that the reference signal is sent or received based on the beam sending the other reference signal.

[0190] The distances between the target and the second and first measurement devices can be absolute or relative distances. For example, the absolute distance can be a distance value (e.g., 50 meters) or a distance range (e.g., 30 to 50 meters) between the target and the second and first measurement devices. For example, the absolute distance = the distance between the target and the second and first measurement devices + the distance between the target and the first measurement device.

[0191] The above relative distance may be, for example, the distance difference between a reflection path and a direct path, wherein the reflection path is the path that the reference signal takes to reach the first measuring device after being reflected by the target, and the direct path is the path that the reference signal takes to reach the first measuring device directly.

[0192] Optionally, the information of the above-mentioned target may include one or more of the following: information indicating the identification 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 a reference signal, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the measuring device.

[0193] 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 a reference signal, wherein the reference signal is used to measure the target; or information indicating the distance between the target and the second measuring device and the first measuring device, but does not include information indicating the identification of the target.

[0194] 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 the first measurement device has measurement capability, whether the first measurement device has deformation detection capability, the location of the first measurement device, the direction of the antenna panel of the first measurement device, or the number of antenna elements of the first measurement device. Accordingly, the first network element receives the first message.

[0195] The first message may be actively reported by the first measurement device or requested to be reported by the first network element, which is not limited in this application.

[0196] For a detailed explanation of the first message, please refer to the explanation of the first message reported by the measuring device in FIG3 , which will not be repeated here.

[0197] Optionally, the method 400 further includes step 402: the second measurement device may also report a third message to the first network element, where the third message indicates one or more of the following: whether the second measurement device has measurement capability, whether the second measurement device has deformation detection capability, the location of the second measurement device, the orientation of the antenna panel of the second measurement device, or the number of antenna elements of the second measurement device. A detailed explanation of the third message can be found in the explanation of the first message reported by the measurement device in FIG3 , and is not further described here.

[0198] Optionally, the method 400 further includes steps 403 and 404, wherein step 403 involves the first network element sending a second message requesting configuration information for reference signal resources. Accordingly, the second measurement device receives the second message. Step 404 involves the second measurement device sending configuration information. Accordingly, the first network element receives the configuration information.

[0199] The configuration information may be used to configure one or more of the following: time domain resources, frequency domain resources, or spatial domain resources, etc. Exemplarily, the configuration information includes a reference signal period, one or more beam directions, or at least one time-frequency resource.

[0200] It can be understood that when the device sending the reference signal is a terminal (ie, the second measurement device is a terminal), the first network element may send a second message to the network device serving the terminal to request the network device to configure reference signal resources.

[0201] In step 420 , the first measurement device measures the target based on the target information.

[0202] The first measuring device measuring the target based on the target information may specifically include the first measuring device receiving an echo signal and obtaining a measurement result based on the echo signal.

[0203] The second measuring device sends a reference signal in a specific beam direction, or sends an omnidirectional reference signal. Correspondingly, the first measuring device receives the echo signal and obtains a measurement result based on the echo signal.

[0204] Optionally, the 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 target, and the measurement result includes one or more of the following: the target identifier, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Accordingly, the first network element receives the measurement result. The first network element may also perform deformation calculation on the target based on the measurement result. A detailed description of the measurement result can be found in Figure 3 and is not further described here.

[0205] Based on the above technical solution, the first measurement device can receive a measurement request from the first network element, which is used to request measurement of a target. In other words, the first measurement device can determine which target to measure, and provides a method for measuring a known (or specific) target. That is, the first network element can flexibly specify which target to measure.

[0206] Figure 5 is a schematic flow chart of a signal transmission method 500 provided in an embodiment of the present application. Figure 5 only describes the method by taking the interaction between a network device and a first network element as an example, and should not constitute any limitation to the present application. The network device in Figure 5 can also be replaced by a component configured in the network device (such as a chip, a chip system, a processor, etc.), or a logic module or software that can implement all or part of the functions of the network device. The first network element can be replaced by a component configured in the first network element (such as a chip, a chip system, a processor, etc.), or a logic module or software that can implement all or part of the functions of the first network element.

[0207] The method shown in Figure 5 can be applied to a single-station sensing scenario, where a network device senses / measures a target, sends a reference signal, and receives an echo signal. The method shown in Figure 5 can also be applied to a dual-station sensing scenario, where a network device sends a reference signal and another network device or terminal receives an echo signal.

[0208] In step 510, the first network element sends a fourth message requesting reference signal configuration. The fourth message includes target information. Accordingly, the network device receives the fourth message. In other words, while requesting reference signal configuration, the first network element also indicates the target information to the network device, facilitating measurement of the target.

[0209] The target information may indicate the beam direction of the reference signal. The fourth message is used to request configuration of the reference signal, and may also be replaced by the fourth message being used to request configuration information of the reference signal.

[0210] Exemplarily, the first network element sends a fourth message requesting configuration of a reference signal, the fourth message including target information. Accordingly, the network device receives the fourth message and configures the reference signal, or in other words, configures reference signal resources, such as time domain resources, frequency domain resources, and spatial domain resources for transmitting the reference signal. It will be appreciated that the network device may configure, based on the target information, resources for the reference signal used to measure the target, and transmit the reference signal on the resources to measure the target.

[0211] Optionally, the target information includes information indicating an identifier of the target. For information indicating an identifier of the target, please refer to the relevant description of FIG3 , which will not be repeated here.

[0212] Optionally, the target information further includes one or more of the following: information indicating the target's location; information indicating the target's orientation or angle; information indicating the beam direction of a reference signal used to measure the target; or information indicating the distance between the target and the network device. A detailed explanation of the above information can be found in Figure 3 and is not repeated here.

[0213] In step 520, the network device sends a reference signal.

[0214] Exemplarily, the network device may send a reference signal on a configured reference signal resource.

[0215] Optionally, the method 500 further includes: the network device sending a first message to the first network element, where the first message indicates one or more of the following: whether the network device has measurement capability, whether the network device has deformation detection capability, the location of the network device, the direction of the antenna panel of the network device, or the number of antenna elements of the network device. Accordingly, the first network element receives the first message.

[0216] The first message may be reported by the network device on its own initiative or by the first network element upon request, which is not limited in this application. Detailed explanation of the first message can be found in FIG3 and will not be repeated here.

[0217] It will be understood that when the network device is both a transmitter of the reference signal and a receiver of the echo signal, the method 500 further includes: the network device sending a measurement result to the first network element. The measurement result is obtained by measuring the target, and the measurement result includes one or more of the following: a target identifier, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Accordingly, the first network element receives the measurement result. The first network element may also perform deformation calculation on the target based on the measurement result.

[0218] Based on the above technical solution, the fourth message for requesting the configuration of the reference signal may include target information, that is, the first network element indicates the target information to the network device while requesting the configuration of the reference signal, so that the network device can measure the target. In addition, compared with additional requests for measuring the target, such as sending a measurement request, it is beneficial to reduce signaling overhead.

[0219] Figure 6 is a schematic flow chart of a signal transmission method 600 provided in an embodiment of the present application. Figure 6 only describes the method by taking the interaction between a network device and a first network element as an example, and should not constitute any limitation to the present application. The network device in Figure 6 can also be replaced by a component configured in the network device (such as a chip, a chip system, a processor, etc.), or a logic module or software that can implement all or part of the functions of the network device. The first network element can be replaced by a component configured in the first network element (such as a chip, a chip system, a processor, etc.), or a logic module or software that can implement all or part of the functions of the first network element.

[0220] The method shown in Figure 6 can be applied to a single-station sensing scenario, where the terminal senses / measures the target, that is, the terminal sends a reference signal and receives an echo signal. The method shown in Figure 6 can also be applied to a dual-station sensing scenario, where the terminal sends a reference signal and another network device or terminal receives the echo signal.

[0221] In step 610, the first network element sends a fourth message requesting reference signal configuration. The fourth message includes target information. Accordingly, the network device receives the fourth message. In other words, while requesting reference signal configuration, the first network element also indicates the target information to the network device, facilitating measurement of the target.

[0222] The target information may indicate the beam direction of the reference signal. The fourth message is used to request configuration of the reference signal, and may also be replaced by the fourth message being used to request configuration information of the reference signal.

[0223] Exemplarily, the first network element sends a fourth message to request configuration of a reference signal, where the fourth message includes target information. Accordingly, the network device receives the fourth message and configures the reference signal, or in other words, configures reference signal resources, such as time domain resources, frequency domain resources, and spatial domain resources for transmitting the reference signal. It is understood that the network device can configure reference signal resources for measuring the target based on the target information, and send the configuration information of the reference signal resources to the terminal, so that the terminal can measure the target based on the configuration. Specifically, the terminal can send the reference signal on the configured resources to complete the measurement of the target.

[0224] Optionally, the target information includes information indicating an identifier of the target. For information indicating an identifier of the target, please refer to the relevant description of FIG3 , which will not be repeated here.

[0225] Optionally, the target information further includes one or more of the following: information indicating the target's location; information indicating the target's orientation or angle; information indicating the beam direction of a reference signal used to measure the target; or information indicating the distance between the target and the network device. A detailed explanation of the above information can be found in Figure 3 and is not repeated here.

[0226] In step 620, the network device sends a fifth message to the terminal, where the fifth message is used to configure the reference signal. Correspondingly, the terminal receives the fifth message.

[0227] As an example and not a limitation, the fifth message may include time domain resources, frequency domain resources, or spatial domain resources for transmitting a reference signal. Exemplarily, the fifth message includes a reference signal period, one or more beam directions, or at least one time-frequency resource.

[0228] 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. For another example, the terminal sends a reference signal based on the fifth message, and another terminal or network device receives the echo signal. It is understandable that the recipient of the echo signal may also report the measurement result to the first network element, and the measurement result may include one or more of the following: target identification, time measurement information, angle measurement information, energy measurement information, or phase measurement information. Accordingly, the first network element receives the above measurement results. The first network element may also perform deformation calculation on the target based on the measurement results.

[0229] Optionally, the method 600 further includes: the network device sending a first message to the first network element, where the first message indicates one or more of the following: whether the network device has measurement capability, whether the network device has deformation detection capability, the location of the network device, the direction of the antenna panel of the network device, or the number of antenna elements of the network device. Accordingly, the first network element receives the first message.

[0230] The first message may be reported by the network device on its own initiative or by the first network element upon request, which is not limited in this application. Detailed explanation of the first message can be found in FIG3 and will not be repeated here.

[0231] Based on the above technical solution, the fourth message used to request the configuration of the reference signal may include target information, that is, the first network element indicates the target information to the network device while requesting the configuration of the reference signal. Compared with additional requests for measuring the target, such as sending a measurement request, this is conducive to reducing signaling overhead.
