It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a special hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0105] In some embodiments, the network side device and the terminal can have a sensing capability in addition to the communication capability. The sensing capability, i.e., one or more devices having the sensing capability, can sense the position, distance, speed, etc. of a target object, or detect, track, identify, image, etc. the target object, event or environment, etc. through the transmission and reception of wireless signals. Some sensing functions and application scenarios are shown in Table 1:

[0106] Table 1

[0107] It should be noted that the sensing categories shown in Table 1 above are only an example, and the categories of sensing measurement are not limited in the embodiments of the present application.

[0108] In addition, the embodiments of the present application can be applied to a communication-sensing integrated scenario. The communication-sensing integration refers to the integration of communication and sensing functions through spectrum sharing and hardware sharing in the same system. The system can sense the position, distance, speed, etc. while transmitting information, and detect, track, identify, etc. the target device or event. The communication system and the sensing system complement each other to improve the overall performance and bring better service experience.

[0109] For example, the integration of communication and radar is a typical communication-sensing integrated (communication-sensing fusion) application, and the integration of communication and radar system can bring many advantages, such as cost saving, size reduction, power consumption reduction, spectrum efficiency improvement, mutual interference reduction, etc., thereby improving the overall system performance.

[0110] In the embodiments of the present application, according to the differences between the sensing signal transmission node and the reception node, there can be, but are not limited to, six kinds of sensing links shown in FIG. 2. It should be noted that each sensing link in FIG. 2 is exemplified by one transmission node and one reception node. In actual systems, different sensing links can be selected according to different sensing requirements, and the transmission node and the reception node of each sensing link can be one or more, and the actual sensing system can include multiple different sensing links. In addition, the sensing targets in FIG. 2 are taken as examples of people and vehicles, and it is assumed that neither people nor vehicles carry or install signal receiving / transmitting devices. The sensing targets in actual scenarios will be more diverse.

[0111] Sensing link 1: Base station self-emission self-reception sensing. In this mode, the base station transmits a sensing signal and obtains a sensing result by receiving the echo of the sensing signal.

[0112] Sensing link 2: Inter-base station air interface sensing. In this mode, base station 2 receives the sensing signal transmitted by base station 1 and obtains a sensing result.

[0113] Sensing link 3: Uplink air interface sensing. In this mode, the base station receives the sensing signal transmitted by the terminal and obtains a sensing result.

[0114] Sensing link 4: Downlink air interface sensing. In this mode, the terminal receives the sensing signal transmitted by the base station and obtains a sensing result.

[0115] Sensing link 5: Terminal self-emission self-reception sensing. In this mode, the terminal transmits a sensing signal and obtains a sensing result by receiving the echo of the sensing signal.

[0116] Sensing link 6: Inter-terminal sidelink sensing. For example, terminal 2 receives the sensing signal transmitted by terminal 1 and obtains a sensing result, or terminal 1 receives the sensing signal transmitted by terminal 2 and obtains a sensing result.

[0117] Radar can be divided into single-base radar and double / multi-base radar according to whether the transmitter and receiver are separated. Double-base radar generally requires the transmitting and receiving antennas to be far apart, comparable to the radar range.

[0118] Among them, the external radiation source radar is a special case of double-base radar, which uses related electromagnetic wave detection theory and signal processing technology to obtain non-cooperative electromagnetic signals transmitted by a third party (such as a communication base station), and realizes detection, positioning, tracking and identification of targets. The external radiation source radar is also called passive radar, double / multi-base passive radar, passive radar, non-cooperative illumination source radar or non-cooperative passive detection system.

[0119] Double-base radar sensing result calculation generally needs to be based on reference channel (direct path) signal and monitoring channel (reflected path) signal. A typical double-base radar architecture diagram is shown in FIG. 3, where the left side represents a two-dimensional space and the right side represents a three-dimensional space. Among them, R T is the distance from the signal transmitting end (Tx) to the target, R R is the distance from the signal receiving end (Rx) to the target, L is the baseline distance, and β is the double-base angle. The target (i.e. Target in the figure) is the measurement target.

[0120] In some embodiments, the signaling transmission between the wireless access network device and the terminal, between different terminals is through Radio Resource Control (RRC) signaling or Medium Access Control Control Element (MAC CE) or layer 1 signaling or other newly defined sensing signaling; the signaling transmission between the sensing network function and the terminal can be through Non-Access-Stratum (NAS) signaling (forwarded through the AMF) or through RRC signaling or MAC CE or layer 1 signaling or other newly defined sensing signaling; the interaction between the sensing network function and the base station can be forwarded to the wireless access network through the N2 interface by the AMF; or the core network sensing network function is sent to the UPF, and the UPF is sent to the wireless access network through the N3 interface; or sent to the wireless access network (such as the base station) through a newly defined interface; the signaling transmission between the wireless access network devices can be through the Xn interface.

[0121] In some embodiments, the sensing network function can also be called a sensing network element or a sensing management function (Sensing MF), which can be on the RAN side or the core network side, refers to a network node in the core network or RAN responsible for at least one function of sensing request processing, sensing resource scheduling, sensing information interaction, sensing data processing, etc., which can be based on the upgrade of AMF or LMF in the mobile communication network, or other network nodes or newly defined network nodes. Specifically, the function characteristics of the sensing network function / sensing network element can include at least one of the following:

[0122] Interact with the wireless signal sending device or the wireless signal measuring device (including the target terminal or the serving base station of the target terminal or the base station associated with the target area) to obtain the target sensing result or the value of the sensing measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device, wherein the target information includes sensing processing request, sensing capability, sensing auxiliary data, sensing measurement quantity type, and sensing resource configuration information, etc., wherein the wireless signal can also be referred to as a sensing signal;

[0123] According to the type of sensing service, the sensing service consumer information, the required Quality of Service (QoS) requirement information, the sensing capability of the wireless signal sending device, the sensing capability of the wireless signal measuring device, etc. to determine the sensing method to be used, which can include: wireless access network device A sends to wireless access network device B, or wireless access network device sends to terminal, or wireless access network device A self-sending and self-receiving, or terminal sending to wireless access network device, or terminal self-sending and self-receiving, or terminal A sending to terminal B, etc.

[0127] In order to better understand the technical solutions provided by the embodiments of the present application, the definition of the information element (Information Element) related to measurement in the embodiments of the present application can be as follows:

[0128] The signal measurement method, device and equipment provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and application scenarios.

[0129] Please refer to FIG. 4, which is a flowchart of a signal measurement method provided by an embodiment of the present application, as shown in FIG. 4, including the following steps:

[0130] Step 401: A first device measures a first signal to obtain first measurement information, wherein the first measurement information is used for at least one of the following: identifying a first type of target path, identifying a second type of target path, identifying a first type of measurement target, and identifying a second type of measurement target.

[0131] The first measurement information includes at least one of the following:

[0132] at least one of the following:

[0133] at least one of the following:

[0134] The target path is a signal path in the first signal associated with the measurement target.

[0135] The first device can be a terminal or a network side device.

[0136] In the embodiments of the present application, the measurement target is a target that needs to be measured, for example, a target that needs to be measured in a perception measurement or a position measurement, which can be a target object such as a vehicle or an obstacle, or the measurement target can be a pedestrian, etc. In some embodiments, when the measurement target is a passive target, the embodiments of the present application can measure the position information of the passive target.

[0137] In the embodiments of the present application, the measurement can be perception, that is, the position of the measurement target is obtained through perception, such as the position information of a passive target.

[0138] The first signal can be a special signal for a perception service, or a communication signal such as a reference signal or a synchronization signal, etc.

[0139] The special signal for the perception service can be a perception signal generated based on a Chirp or a Frequency Modulated Continuous Wave (FMCW) signal, or a perception signal generated based on a Pseudo-Random (PN) sequence or a ZC sequence, etc.

[0140] The reference signal can be a Demodulation Reference Signal (DMRS), a Channel State Information Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), or a Positioning Reference Signal (PRS), etc.

[0141] The synchronization signal can be a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS), etc.

[0142] The signal carrying communication data can be a Physical downlink shared channel (PDSCH), a Physical Uplink Shared Channel (PUSCH), a Physical Downlink Control Channel (PDCCH), or a Physical Uplink Control Channel (PUCCH), etc.

[0143] The first device can measure the first signal to obtain the first measurement information.

[0144] The departure angle information can be a departure angle or a departure angle difference value information.

[0145] The arrival angle information can be an arrival angle or an arrival angle difference value information.

[0146] The associated measurement information of the departure angle information refers to measurement information used to calculate the departure angle information, such as phase information, amplitude information, spectrum information, and the like.

[0147] The departure angle information can be calculated by the second device or the third device in a case where the first measurement information includes the associated measurement information of the departure angle information.

[0148] The signal path associated with the measurement target in the first signal can be a signal path affected by the measurement target in the measurement signal or a signal path passing through the measurement target, or a signal path associated with a portion of the first signal reflected in propagation through the measurement target.

[0149] In the measurement scene, there can be one or more target paths, for example, a signal path associated only with the measurement target or a target path reflected only through the measurement target, a target path reflected through the measurement target and an environmental object, and the like.

[0150] In a case where the at least one target path is a plurality of target paths, the plurality of target paths can include different types of target paths, such as a first type of target path and a second type of target path.

[0151] In some embodiments, the first type of target path includes one of the following:

[0152] A real target path, a signal path associated only with the measurement target, or a signal path reflected only through the measurement target.

[0153] The real target path refers to a target path associated with a real target, and the real target is a target that needs to be measured in the measurement process, such as a target that needs to be positioned in the positioning measurement process. For example, vehicle A is measured, and vehicle A is a real target, and other vehicles (such as vehicle B) or pedestrians and the like are not real targets. The real target path is a path that is reflected only once through the measurement target.

[0154] The signal path associated only with the measurement target refers to a signal path associated only with the measurement target, and not associated with an environmental object.

[0155] The signal path reflected only through the measurement target refers to a signal path reflected only through the measurement target, and not a signal path reflected through an environmental object.

[0156] In some embodiments, the second type of target path comprises one of:

[0157] a false target path, a signal path associated with a measurement target and an environmental object, a signal path passing through a measurement target and an environmental object, a signal path passing through multiple different measurement targets for multiple reflections.

[0158] The false target path refers to a target path associated with a false target, which is not a target to be measured in a measurement process. For example, in a positioning measurement process, a target to be positioned is a real target, and other targets (e.g., a vehicle B) or pedestrians are false targets. In other words, a target other than a real target is a false target. The false target path can be a signal path associated with an environmental object or a signal path passing through multiple different measurement targets for multiple reflections.

[0159] The signal path associated with a measurement target and an environmental object refers to a signal path associated with a measurement target and also associated with an environmental object.

[0160] The signal path passing through a measurement target and an environmental object refers to a signal path reflected by a measurement target and also reflected, diffracted, or refracted by an environmental object.

[0161] For example, a first device receives a first signal and performs target path detection (or target detection). The target path includes a path passing through a measurement target for one reflection, i.e., a real target path, or a path passing through a measurement target and an environmental object (which can also be referred to as an environmental target, where the environmental target can also be another different measurement target, i.e., a different measurement target corresponding to a measurement, such as a measurement target being a vehicle and an environmental target being a pedestrian or a different vehicle) for at least two reflections (which can also include a path passing through diffraction, refraction, etc.), i.e., a false target path. As shown in FIG. 5, the false target path (Tx-Target-EO-Rx) can be considered to satisfy a target path feature, such as a Doppler satisfying a specific range and a signal path power exceeding a preset threshold, and the signal path is determined to be a target path after constant false alarm rate (CFAR) detection. As shown in FIG. 5, the propagation path Tx-Target-Rx corresponds to a real target path, and the propagation path Tx-Target-EO-Rx corresponds to a false target path, where EO refers to an environmental object.

[0162] In some embodiments, the first type of measurement target comprises one of:

[0163] a real measurement target, a measurement target that actually exists in an environment, and a measurement target associated with the first type of target path.

[0164] The real measurement target, the measurement target that really exists in the environment, can be understood as a target that is really to be measured, as shown in FIG. 5.

[0165] In some embodiments, the second type of measurement target includes one of the following:

[0166] The false measurement target, the measurement target that does not really exist in the environment, the measurement target associated with the second type of target path.

[0167] The false measurement target, the measurement target that does not really exist in the environment, can be understood as a false target in a measurement scene, as shown in FIG. 5.

[0168] In the embodiments of the present application, the first measurement information is used for at least one of identifying the first type of target path, identifying the second type of target path, identifying the first type of measurement target, and identifying the second type of measurement target, which can be understood as that the first measurement information can directly or indirectly identify at least one of the first type of target path, the second type of target path, the first type of measurement target, and the second type of measurement target. For example, based on the first measurement information, at least one of the first type of target path, the second type of target path, the first type of measurement target, and the second type of measurement target can be identified, or based on the first measurement information, feature information that can identify at least one of the first type of target path, the second type of target path, the first type of measurement target, and the second type of measurement target is determined.

[0169] In the embodiments of the present application, identifying the first type of target path, identifying the second type of target path, identifying the first type of measurement target, and identifying the second type of measurement target can be performed by the first device, or can be performed by the second device or the third device, as described below.

[0170] In the embodiments of the present application, since the first measurement information is used for at least one of identifying the first type of target path, identifying the second type of target path, identifying the first type of measurement target, and identifying the second type of measurement target, measurement information used for at least one of identifying the first type of target path, identifying the second type of target path, identifying the first type of measurement target, and identifying the second type of measurement target can be measured, that is, the device can measure more useful information, thereby improving the measurement performance of the device. In addition, the first measurement information can support identifying the first type of target path, identifying the second type of target path, identifying the first type of measurement target, and identifying the second type of measurement target, thereby improving the measurement reliability for the measurement target, for example, improving the reliability of the position information of the measurement target.

[0171] As an optional implementation, the departure angle information includes at least one of: a departure angle of the target range; and departure angle difference information between the target range and a reference range of the first signal.

[0172] The departure angle can be AoD information or ZoD, or the departure angle can also be a value of a trigonometric function in sin or cos form corresponding to the departure angle.

[0173] The departure angle difference information between the target range and the reference range of the first signal can be angle difference information between a departure angle of the target range of the first signal and a departure angle of the reference range of the first signal.

[0174] The reference range can be a pre-specified or protocol-agreed signal range, for example, the reference range includes at least one of:

[0175] LOS range, first-arrival range, and signal range reflected by a known target.

[0176] In some implementations, the LOS range can be a first-arrival range, for example, when a LOS condition is met between a signal transceiver device, that is, the LOS range is the first-arrival range.

[0177] In some implementations, the signal range reflected by a known target can be a signal range reflected by a smart intelligent surface (RIS), backscatter, or other known passive targets.

[0178] In this implementation, either one or both of the departure angle of the target range and the departure angle difference information can be used to identify the first type of target range, identify the second type of target range, identify the first type of measurement target, and identify the second type of measurement target.

The ZOD based on the local coordinate system can be understood as ZOD in the local coordinate system or ZOD relative to the local coordinate system.

[0185] The local coordinate system can be a reference coordinate system defined based on a terminal antenna array, or a reference coordinate system defined based on the terminal itself, for example, the horizontal direction of the terminal screen is the x' axis, the vertical direction of the terminal screen is the y' axis, and the normal direction of the terminal screen is the z' axis. Alternatively, the local coordinate system can also be a reference coordinate system defined based on a BS antenna array, for example, the normal direction of the BS antenna array is the x' axis, the horizontal direction of the BS antenna array is the y' axis, and the vertical direction of the BS antenna array is the z' axis, as shown in FIG. 6a.

[0186] The AOD based on the global coordinate system can be understood as AOD in the global coordinate system or AOD relative to the global coordinate system.

[0187] The global coordinate system can be an east-north-sky reference coordinate system, for example, as shown in FIG. 6b.

[0188] In the embodiments of the present application, the conversion relationship between the local coordinate system and the global coordinate system is that the angle of departure information based on the local coordinate system can be used to calculate the angle of departure information based on the global coordinate system, and the angle of departure information based on the global coordinate system can be used to calculate the angle of departure information based on the local coordinate system, for example, as shown in FIG. 6b, the conversion relationship information between the local coordinate system and the global coordinate system includes: the rotation angle α of the local coordinate system around the z axis, the rotation angle β of the local coordinate system around the y axis, and the rotation angle γ of the local coordinate system around the x axis.

[0192] The angle of arrival difference information between the target path and the reference path of the first signal can be the angle difference information between the angle of departure of the target path of the first signal and the angle of arrival of the reference path of the first signal.

[0193] In this embodiment, either or both of the target path AoA and the above-mentioned angle difference information can be used to identify the first type of target path, identify the second type of target path, identify the first type of measurement target, and identify the second type of measurement target.

[0218] The measurement information associated with the angle of departure information includes at least one of the following, which can be understood as being calculated based on any one or any combination of multiple items, and can be calculated based on the correspondence between the at least one item and the angle of departure, for example: a mapping relationship or a calculation formula between the at least one item and the angle of departure can be pre-configured, so as to obtain the angle of departure information, such as pre-defining the mapping relationship between the amplitude, phase, phase difference of each port and the angle of departure, or pre-defining the mapping relationship between the amplitude, phase, phase difference of multiple resources and the angle of departure, such as pre-defining the mapping relationship between multiple precoding information and the angle of departure, such as pre-defining the mapping relationship between multiple signal resources and the angle of departure, etc. It should be noted that the calculation method of the angle of departure information is not limited in the embodiments of the present application.

[0235] If the second device uses dual-polarized antennas for transmission and follows the default mapping rule, different resources or ports can be first mapped to different antennas corresponding to polarization 1, and then mapped to different antennas corresponding to polarization 2; or different resources are only mapped to polarization 1 or polarization 2.

[0294] It should be noted that the calculation of the first feature information and the second feature information described above is only an example, and the embodiments of the present application are not limited thereto.

[0295] Since the first operation is performed based on the first feature information corresponding to at least one target path and the second feature information corresponding to the at least one target path, the second measurement information is obtained, which can support multiple feature information to identify the first type of target path, identify the second type of target path, identify the first type of measurement target, and identify the second type of measurement target.

[0296] The first operation described above can be based on the following principles to identify the first type of target path, identify the second type of target path, identify the first type of measurement target, and identify the second type of measurement target:

[0297] For the first type of target path, the first feature information and the second feature information are the feature information of the same target, i.e., the feature information of the real target;

[0298] For the second type of target path, the first characteristic information and the second characteristic information correspond to different characteristic information of false targets.

[0299] In some embodiments, the at least one target path includes a first target path, wherein:

[0300] In a case where the first characteristic information of the first target path matches the second characteristic information of the first target path, the first target path is the first type of target path, or the measurement target corresponding to the first target path is the first type of measurement target; and / or

[0301] In a case where the first characteristic information of the first target path does not match the second characteristic information of the first target path, the first target path is the second type of target path, or the measurement target corresponding to the first target path is the second type of measurement target.

[0302] Wherein, the first target path can be understood as any target path in the at least one target path, that is, any target path can determine the type of target path in the above manner.

[0303] The first characteristic information of the first target path matching the second characteristic information of the first target path can be that the first characteristic information of the first target path is the same as or close to the second characteristic information of the first target path.

[0304] In some embodiments, the first characteristic information of the first target path not matching the second characteristic information of the first target path includes at least one of the following:

[0305] The difference between the first target position information and the second target position information exceeds a preset threshold;

[0306] The first distance information and the distance of the first distance information minus the signal propagation path length associated with the first target path exceed a preset threshold;

[0307] The first propagation time delay information and the propagation time delay of the first propagation time delay information minus the signal propagation time delay associated with the first target path exceed a preset threshold;

[0308] The difference between the first arrival angle information and the second arrival angle information exceeds a preset threshold;

[0309] The difference between the first departure angle information and the second departure angle information exceeds a preset threshold;

[0310] The difference between the first incoming wave angle information and the second incoming wave angle information exceeds a preset threshold;

[0311] The difference between the first de-waving included angle information and the second de-waving included angle information exceeds a preset threshold.

[0312] The preset threshold can be a protocol agreement or a network side device, and can be set according to actual needs, which is not limited.

[0313] For example, when the first characteristic information and the second characteristic information of the first target path satisfy at least one of the following conditions, the target path is determined as the second type of target path:

[0314] The Euclidean distance between the first target position information (x T1 ,y T1 ,z T1 ) and the second target position information (x T2 ,y T2 ,z T2 ) exceeds a preset threshold, that is

[0315] The sum of the first distance information d′ Target-Rx and the second distance information d′ Tx-Target minus the signal propagation path length d Path associated with the target path exceeds a preset threshold, that is |d′ Target-Rx +d′ Tx-Target -d Path |>ξ, wherein for the first type of target path, d Path =d Target-Rx +d Tx-Target =d′ Target-Rx +d′ Tx-Target , and for the second type of target path, d Path =d Tx-Target +d Target-EO +d EO-Rx =d Tx-FT1 +d fT1-Rx =d Tx-FT2 +d FT2-Rx .

[0316] The difference between the first arrival angle information and the second arrival angle information exceeds a preset threshold, specifically, the difference between the first arrival azimuth angle and the second arrival azimuth angle exceeds a preset threshold, that is |AoA T1 -AoA T2 |>ξ, or the difference between the first arrival zenith angle and the second arrival zenith angle exceeds a preset threshold, that is |ZoA T1 -ZoA T2 |>ξ.

[0317] The difference between the first departure angle information and the second departure angle information exceeds a preset threshold, specifically, the difference between the first departure azimuth angle and the second departure azimuth angle exceeds a preset threshold, that is |AoD T1AoD T2 |ξ, or the difference between the first departure zenith angle and the second departure zenith angle exceeds a preset threshold, i.e., |ZoD T1 -ZoD T2 |ξ;

[0318] first arrival wave angle information θ R1 and second arrival wave angle information θ R2 exceeds a preset threshold, i.e., |θ T1 -θ R2 |ξ;

[0319] first departure wave angle information θ T1 and second departure wave angle information θ T2 exceeds a preset threshold, i.e., |θ T1 -θ T2 |ξ.

[0320] The above ξ represents a preset threshold.

[0321] In addition, the above distance information can also represent corresponding time delay information.

[0322] In the above manner, the first type of target path can be accurately identified, and the second type of target path can be identified.

[0323] The first type of measurement target is a measurement target associated with the first type of target path, and the second type of measurement target is a measurement target associated with the second type of target path. That is, identifying the first type of target path and identifying the second type of target path also indirectly identifies the first type of measurement target and identifies the second type of measurement target.

[0324] In some embodiments, the target path can be a path that is reflected twice by the measurement target and the environment target, or the target path can be a path that is reflected three times or more by the measurement target and the environment target, as shown in FIG. 8. For a path that is reflected three times or more, the judgment condition of the target path is met, and environment target information, such as position information of the environment target, or angle information relative to the receiving device or the transmitting device, or distance information relative to the receiving device or the transmitting device, can be obtained. According to the measurement information associated with the angle and time delay of the target path and the environment target information, it is assisted to judge whether the target path is a second type of target path. For example, if the difference between the angle (e.g., the azimuth of arrival and the zenith of arrival) of the target path and the angle of the environment target relative to the receiving device is less than a preset threshold (i.e., the angle of arrival of the target path is considered to be the same as the angle of the environment target relative to the receiving device), and the propagation distance corresponding to the target path is greater than the propagation distance corresponding to the single reflection path of the environment target (i.e., the propagation distance corresponding to the target path is greater than the propagation distance corresponding to the single reflection path of the environment target), it is considered that the target path is a second type of target path.

[0325] The second measurement information is measurement information to which the first operation is performed, such as an identification result.

[0326] In some embodiments, the second measurement information includes at least one of:

[0327] an angle of departure of the first type of target path;

[0331] an angle of departure of a reference path of the first signal;

[0332] an angle of arrival of a reference path of the first signal;

[0333] a propagation time difference between the first type of target path and a reference path of the first signal;

[0334] a propagation distance difference between the first type of target path and a reference path of the first signal;

[0335] propagation time, relative time of arrival, or propagation distance information of the first type of target path;

[0336] distance information of the first type of measurement target to the first device;

[0337] distance information of the first type of measurement target to a second device;

[0340] a number of detected target paths;

[0341] a detected target path type indication;

[0342] a detected measurement target type indication;

[0344] The target path type indication can be used to indicate whether the reported parameter information of the target path corresponds to the parameter information of the first type of target path, or the information of the first type of target path and the second type of target path as a whole, for example, when it is indicated that only the information of the first type of target path is reported (at this time, the device reporting the information has the ability to identify the target path), only the second measurement information is reported, otherwise, the measurement information of the entire target path is reported.

[0345] As indicated, the first type of target path or the second type of target path is detected, or the first type of measurement target or the second type of measurement target is detected.

In some embodiments, the first type of target path, the second type of target path, the first type of measurement target, and the second type of measurement target can be directly identified based on the first measurement information. For example, for some specific scenarios, a mapping relationship with the departure angle target path is established in advance, such as the absence of the second type of target path at a specific departure angle in the scenario, or the absence of the second type of target path at a specific arrival angle in the scenario.

To avoid repeated description, this embodiment will not be described again.

[0745] The following takes measurement as an example, and the method provided by the embodiment of the application is exemplified through multiple embodiments:

[0746] Embodiment one:

[0747] This embodiment mainly describes the calculation of the first feature information.

[0748] This embodiment describes the calculation of the first feature information based on the angle of arrival, including the calculation of target position information, distance information, angle of arrival information, angle of departure information, incoming wave angle, and outgoing wave angle in the first feature information.

[0749] Wherein, the position information of the measurement target based on the angle of arrival in the three-dimensional space is calculated as follows:

[0750] The device for calculating the position information of the measurement target obtains one or more of the following information: target radial AoA T (i.e. the first angle of arrival information), target radial ZoA T (i.e. the first angle of arrival information), LOS radial AoA L , LOS radial ZoA L , the time delay difference Δτ of the target radial and the LOS radial (or the first radial or the reference radial reflected by the known target), or the propagation distance difference Δd = c·Δτ of the target radial and the LOS radial (c represents the speed of light), the absolute time delay τ of the LOS radial (or the first radial or the reference radial reflected by the known target) L (or the distance d Tx-Tx = c·τ T between the signal transceiver devices, i.e. the propagation distance of the LOS radial). Wherein, the LOS radial can be considered as the first radial in general (the signal transceiver devices satisfy the LOS condition).

[0751] Wherein, AoA L , ZoA L , τ L may be the LOS radial related information obtained by measuring the signal, or can be calculated according to the position information of the signal transmitting device (x Tx , y Tx , z Tx ), the position information of the signal receiving device (x Rx , y Rx , z Rx ):

[0752] AoA L = atan2 (y Tx - y Rx , x Tx - x Rx ), atan2 represents the four quadrant inverse tangent function value;

[0753] acos represents the inverse cosine function value.

[0754] According to the angle of arrival information of the LOS radial and the target radial, the incident angle (i.e. the first incident angle) θ R between the LOS radial and the target radial is calculated as follows: -1 (sin (ZoA T ) sin (ZoA L ) cos (AoA L - AoA T ) + cos (ZoAT )cos(ZoA L )).

[0755] Calculate the distance between the target and the signal receiving device (i.e., the first distance information d′). Target-Gx )

[0756] Where d Tx-Target +d Target-Rx =Δd+d Tx-Rx =c·(Δτ+τ) L ), where Δτ+τ L That is, the absolute time delay of the target path.

[0757] The target position information (i.e., the first target position information) is calculated based on the distance between the target and the signal receiving device and the angle information of the target diameter.

[0758] Based on the target reflection radius angle AoA in the global coordinate system T ZoA T d Target-Rx Calculate the relative position coordinates (x, y) of the target and the signal receiving device in the global coordinate system. Target-Rx ,y Target-Rx ,z Target-Rx ), where x Target-Rx =d Target-Rx ·sin(ZoA T )·cos(AoA T ), y Target-Rx =d Target-Rx ·sin(ZoA T )·sin(AoA T ), z Target-Rx =d Target-Rx ·cos(ZoA T );

[0759] Then, based on the relative position coordinates with the signal receiving device in the global coordinate system, and the position coordinates of the signal receiving device in the global coordinate system, the position coordinates (x, y, y) of the measurement target in the global coordinate system are calculated. Target ,y Target ,z Target )=(x Target-Rx ,y Target-Rx ,z Target-Rx )+(x Rx ,y Rx ,z Rx ).

[0760] Alternatively, it can be based on the target reflection radius angle AoA′ in the local coordinate system. T ZoA′ T RR Calculate the position coordinates (x′) of the target in the local coordinate system. Target ,y′ Target ,z′ Target ), where x′ Target-Rx =d Target-Rx ·sin(ZoA′ T )·cos(AoA′ T ), y′ Target-Rx =d Target-Rx ·sin(ZoA′ T )·sin(AoA′ T ), z′ Target-Rx =d Target-Rx ·cos(ZoA′ T );

[0761] Then, based on the transformation relationship between the global coordinate system and the local coordinate system, the relative position coordinates (x, y) of the measurement target and the signal receiving device in the global coordinate system are obtained. Target-Rx ,y Target-Rx ,z Target-Rx Then, based on the relative position coordinates with the signal receiving device in the global coordinate system, and the position coordinates of the signal receiving device in the global coordinate system, the position coordinates (x, y, y) of the measurement target in the global coordinate system are calculated. Target ,y Target ,z Target ), namely the aforementioned first target location information (x) T1 ,y T1 ,z T1 ).

[0762] It is important to note that in some applications, what is needed is not the position coordinates of the target in the global coordinate system, but rather the position information of the target relative to the receiving device. This position information can be the position coordinates of the target in a local coordinate system with the receiving device as the reference, or it can be the distance R of the target relative to the receiving device. R And the angle AoA′ relative to the receiving device T ZoA′ T .

[0763] The spatial relationship between the measurement target and the signal transceiver in the bistatic sensing mode is shown in Figures 11a and 11b.

[0764] The x-axis, y-axis, and z-axis are global coordinate system (GCS) axes, while the x'-axis, y'-axis, and z'-axis are local coordinate system (LCS) axes.

[0765] Among them, AoA′ TAoA' is the AOA of the target path in the local coordinate system, i.e. the angle of the projection of the direction vector of the measurement target in the local coordinate system in the x'Oy' plane relative to the x' axis, ZoA' T ZoA is the ZOA of the measurement target in the local coordinate system, i.e. the angle of the direction vector of the measurement target in the local coordinate system relative to the z' axis. AoA' is the azimuth angle of the LOS path in the local coordinate system L and ZoA' is the zenith angle of the LOS path in the local coordinate system L AoA is the azimuth angle of the target path in the global coordinate system T ZoA is the zenith angle of the target path in the global coordinate system T AoA is the azimuth angle of the LOS path in the global coordinate system L ZoA is the zenith angle of the LOS path in the global coordinate system L The definitions of the azimuth angle and the zenith angle of the target path and the LOS path in the global coordinate system are similar and will not be repeated.

[0766] where θ R is the angle of arrival (AOA) of the LOS path and the target path (i.e. the angle between the line connecting the signal transmitting device and the signal receiving device and the line connecting the signal receiving device and the measurement target), which is embodied in the plane determined by the signal transmitting device, the signal receiving device and the measurement target, which can also be referred to as a bistatic plane.

[0767] In particular, in some sensing scenarios, only two-dimensional positioning is required, for example, the signal transmitting device and the measurement target are in the same horizontal plane or approximately in the same horizontal plane, or the signal transmitting device only supports a linear antenna array, and the position of the measurement target is calculated based on single-dimensional angle information and time delay, which can only calculate two-dimensional position coordinate information. The difference between the information acquisition of the position of the measurement target in the two-dimensional space and the information acquisition of the position of the measurement target in the three-dimensional space is that:

[0768] ZoA is the zenith angle of the target path in the global coordinate system T ZoA is the zenith angle of the LOS path in the global coordinate system L In the scenario where the measurement target and the signal receiving device are in the same horizontal plane, it can be defaulted to 90°, i.e. no measurement is required.

[0769] AoA is the azimuth angle of the target path in the global coordinate system T AoA is the azimuth angle of the LOS path in the global coordinate system L is the angle information in the global coordinate system (GCS), and if the acquired angle information is the angle information in the local coordinate system (LCS), for example, ZoA' T is the angle information in the global coordinate system (GCS), and if the acquired angle information is the angle information in the local coordinate system (LCS), for example, ZoA' LFor the case of supporting linear array at the sending end, LCS takes the linear array axis direction as the z' axis, and measures the ZoA angle information in the local coordinate system. In the case of the measurement target and the signal transceiving device being located in the same horizontal plane, the AoA in the local coordinate system can be 0° by default or be omitted, that is, no measurement is needed. Then, the global coordinate system angle information can be calculated according to the conversion relationship information between the local coordinate system and the global coordinate system.

[0770] According to the angle of arrival information of the LOS path and the target path, the incoming wave angle θ between the LOS path and the target path is calculated T L T (in the local coordinate system); optionally, if the measurement target and the signal transceiving device are located in the same horizontal plane, θ R L T mod 180° (calculated in the global coordinate system).

[0771] The position information of the measurement target only contains xOy plane coordinate information and does not contain z axis coordinate information, or only contains longitude and latitude information and does not contain height information.

[0772] Wherein the coordinate system and angle information are defined similarly as in the 3D target positioning scenario, and will not be described again. Wherein, θ R is the incoming wave angle between the LOS path and the target path (that is, the angle between the signal transceiving device connecting line and the signal receiving device and measurement target connecting line), which is embodied on the plane determined by the signal sending device, the signal receiving device and the measurement target. For the case of the measurement target and the signal transceiving device being located in the same horizontal plane, the angle is embodied on the xOy plane of the global coordinate system, and the xOy plane is the bistatic plane at this time.

[0773] In some embodiments, the calculation of the departure angle associated with the measurement target (that is, the first departure angle information) can be obtained according to the position information of the measurement target and the sending device position information, including:

[0774] AoD T = atan2(y Target -y Tx , x Target -x Tx ), and atan2 represents the four quadrant inverse tangent function value;

[0775] acos represents the inverse cosine function value.

[0776] In some embodiments, the calculation of the departure angle associated with the measurement target (that is, the first departure angle information) can be obtained according to the position information of the measurement target and the sending device position information, including: T1 ​​​​The calculation of the target distance information can be obtained according to the target distance information and the transceiver distance information by using a trigonometric function formula, or according to the departure angle associated with the target path and the LOS path, for example:

[0777] θ T = cos -1 (sin(ZoD T )sin(ZoD L )cos(AoD L -AoD T )+cos(ZoD T )cos(ZoD L )) where AoD L and ZoD L represent the LOS path departure azimuth angle and departure zenith angle.

[0778] Embodiment Two:

[0779] This embodiment describes the calculation of the second feature information.

[0780] This embodiment is based on the calculation of the second feature information based on the angle of arrival, including the position information of the measured target in the second feature information, distance information, angle of arrival information, departure angle information, incoming wave angle, and outgoing wave angle.

[0781] The specific calculation process of the position information of the measured target in the three-dimensional space based on the angle of arrival is as follows:

[0782] The device performing the position information calculation of the measured target obtains one or more of the following information: target path AoD T (i.e., the second departure angle information), target path ZoD T (i.e., the second departure angle information), LOS path AoD L , LOS path ZoD L , time delay difference Δτ of the target path and the LOS path (or the first path or the reference path reflected by the known target) (or the propagation distance difference Δd of the target path and the LOS path = c·Δτ, c represents the speed of light), absolute time delay τ L of the LOS path (or the first path or the reference path reflected by the known target) (or the distance L between the signal transceiver devices = c·τ L , i.e., the propagation distance of the LOS path). In general, the LOS path can be considered as the first arrival path.

[0783] wherein AoD L , ZoD L , τ L may be the LOS path related information obtained by measuring the signal, or can be obtained according to the signal transmitting device position information (x Tx,y Tx ,z Tx ), signal receiving device position information (x Rx ,y Rx ,z Rx ) are calculated, for example:

[0784] AoD L = atan2 (y Rx -y Tx , x Rx -x Tx ), atan2 represents the four quadrant inverse tangent function value;

[0785] acos represents the inverse cosine function value.

[0786] According to the LOS path and the target path angle information, the wave departure angle between the LOS path and the target path (i.e. the second wave departure angle information θ T2 ) θ T = cos -1 (sin (ZoD T ) sin (ZoD L ) cos (AoD L -AoD T ) + cos (ZoD T ) cos (ZoD L )) is calculated. The wave departure angle can also be understood as the angle between the direction vector from the signal sending device pointing to the signal receiving device and the direction vector from the signal sending device pointing to the measurement target. The cosine value cos (θ T ) = sin (ZoD T ) sin (ZoD L ) cos (AoD L -AoD T ) + cos (ZoD T ) cos (ZoD L ) of the wave departure angle can also be calculated.

[0787] The distance between the measurement target and the signal sending device (i.e. the second distance information d′ Tx-Target ) is calculated:

[0788] Where d Tx-Target +d Target-Rx = Δd + d Tx-Rx = c · (Δτ + τ L ), Δτ + τ L , which is the absolute time delay of the target path, can also be understood as the signal propagation time delay associated with the target reflection path.

[0789] The position information of the target is calculated based on the distance between the target and the signal receiving device and the angle information of the target diameter.

[0790] Based on the target reflection radius angle AoD in the global coordinate system T ZoD T d Tx-Target Calculate the relative position coordinates (x, y) of the target and the signal transmitting device in the global coordinate system. Target-Tx ,y Target-Tx ,z Target-Tx ), where x Target-Tx =d Tx-Target ·sin(ZoD T )·cos(AoD T ), y Target-Tx =d Tx-Target ·sin(ZoD T )·sin(AoD T ), z Target-Tx =d Tx-Target ·cos(ZoD T );

[0791] Then, based on the relative position coordinates with the signal receiving device in the global coordinate system, and the position coordinates of the signal receiving device in the global coordinate system, the position coordinates (x, y, y) of the measurement target in the global coordinate system are calculated. Target ,y Target ,z Target )=(x Target-Tx ,y Target-Tx ,z Target-Tx )+(x Tx ,y Tx ,z Tx ).

[0792] Alternatively, it can be based on the target reflection radius angle AoD′ in the local coordinate system. T ZoD′ T d Tx-Target Calculate the position coordinates (x′) of the target in the local coordinate system. Target-Tx ,y′ Target-Tx ,z′ Target-Tx ), where x′ Target-Tx =d Tx-Target ·sin(ZoD′ T )·cos(AoD′ T ), y′ Target-Tx =d Tx-Target ·sin(ZoD′ T )·sin(AoD′ T ), z′ Target-Tx =d Tx-Target• cos(ZoD' ) ; T );

[0793] Further, according to the conversion relationship between the global coordinate system and the local coordinate system, the relative position coordinates (x Target-Tx ,y Target-Tx ,z Target-Tx ) of the measurement target and the signal sending device in the global coordinate system are obtained, and further, according to the relative position coordinates of the signal receiving device in the global coordinate system and the position coordinates of the signal receiving device in the global coordinate system, the position coordinates (x Target ,y Target ,z Target ) of the measurement target in the global coordinate system, i.e., the second position information (x T2 ,y T2 ,z T2 )

[0794] It should be noted that in some applications, the position coordinates of the measurement target in the global coordinate system are not required to be obtained, but the position information of the measurement target relative to the sending device is required to be obtained, and the position information can be the position coordinates of the measurement target in the local coordinate system with the sending device as the reference, or the position information can be the distance d Tx-Target of the measurement target relative to the sending device and the angle AoD'x T ,ZoD'x T .

[0795] The spatial position relationship between the measurement target and the signal transceiving device in the bistatic sensing mode is shown in FIG. 12a or FIG. 12b.

[0796] Wherein, the x-axis, the y-axis and the z-axis are the coordinate axes of the global coordinate system (GCS), and the x'-axis, the y'-axis and the z'-axis are the coordinate axes of the local coordinate system (LCS).

[0797] Wherein, AoD'x T is the AoD of the target path in the local coordinate system, i.e., the projection of the direction vector from the signal sending device to the measurement target in the x'O'y' plane in the local coordinate system relative to the x'-axis, and ZoD'x T is the ZoD of the measurement target in the local coordinate system, i.e., the angle of the direction vector from the signal sending device to the measurement target relative to the z'-axis in the local coordinate system. AoD'x T and ZoD'x L are the azimuth angle and the zenith angle of the LOS path in the local coordinate system, and AoDx T , ZoDx T , AoDx L and ZoDx LThe definition is similar and will not be repeated here.

[0798] wherein θ T is the angle between the LOS path and the target path (i.e. the angle between the line connecting the signal transmitting device and the signal receiving device and the line connecting the signal transmitting device and the measurement target, which can also be understood as the angle between the direction vector pointing from the signal transmitting device to the signal receiving device and the direction vector pointing from the signal transmitting device to the measurement target), which is embodied in the plane determined by the signal transmitting device, the signal receiving device and the measurement target, which can also be referred to as the bistatic plane.

[0799] In particular, in some sensing scenarios, only two-dimensional positioning is required, for example, the signal transmitting device and the measurement target are in the same horizontal plane or approximately in the same horizontal plane, or the signal transmitting device only supports a linear antenna array, and the position calculation of the measurement target based on single-dimensional angle information and time delay can only calculate two-dimensional position coordinate information. The difference between the position information acquisition of the measurement target in the two-dimensional space and the position information acquisition of the measurement target in the three-dimensional space is that:

[0800] Target path ZoD in global coordinate system T LOS path ZoD L In the scenario where the measurement target and the signal transmitting device are in the same horizontal plane, it can be defaulted as 90°, i.e. no need to measure.

[0801] Target path AoD T LOS path AoD L is the angle information in the global coordinate system (GCS), if the obtained angle information is the angle information in the local coordinate system (LCS), for example, target path ZoD' T LOS path ZoD' L (for the case of supporting linear array at the transmitting end, the LCS takes the linear array axis direction as the z' axis, and the local coordinate system ZoD angle information is measured, and in the scenario where the measurement target and the signal transmitting device are in the same horizontal plane, the local coordinate system AoD can be defaulted as 0°, or default, i.e. no need to measure), the global coordinate system angle information can be calculated according to the conversion relationship information between the local coordinate system and the global coordinate system.

[0802] According to the departure angle information of the LOS path and the target path, the angle θ T between the LOS path and the target path is calculated L |ZoD' T | (calculated in the local coordinate system); optionally, if the measurement target and the signal transmitting device are in the same horizontal plane, it can also be θ T |AoD' L |AoD' T|mod 180° (calculated in global coordinate system).

[0803] The position information of the measurement target only contains xOy plane coordinate information, does not contain z-axis coordinate information, or only contains longitude and latitude information, and does not contain height information.

[0804] Wherein, the coordinate system and angle information are similar to the definition of 3D target positioning scene, and will not be repeated. Wherein, θ T The angle between the LOS path and the target path (i.e. the angle between the line connecting the signal receiving device and the signal transmitting device and the line connecting the signal transmitting device and the measurement target) is embodied on the plane determined by the signal transmitting device, the signal receiving device and the measurement target. For the case that the measurement target and the signal receiving device are located on the same horizontal plane, the angle is embodied on the xOy plane of the global coordinate system, and the xOy plane is the bistatic plane at this time.

[0805] In some embodiments, the calculation of the angle of arrival associated with the measurement target (i.e. the second angle of arrival information) can be obtained according to the position information of the measurement target and the position information of the transmitting device, including:

[0806] AoA T = atan2 (y Target -y Rx , x Target -x Tx ), atan2 represents the four quadrant inverse tangent function value;

[0807] acos represents the inverse cosine function value.

[0808] Further, the calculation of the angle of departure between the LOS path and the target path (i.e. the second angle of arrival information θ R2 ) can be obtained according to the target distance information and the distance information of the transceiver device using the trigonometric function formula, or according to the angle of arrival associated with the target path and the LOS path, for example:

[0809] θ R = cos -11 (sin(ZoA T ) sin(ZoA L ) cos(AoA L -AoA T ) + cos(ZoA T ) cos(ZoA L )), wherein AoA L and ZoA L represent the azimuth angle of arrival and the zenith angle of arrival of the LOS path.

[1071] This embodiment mainly describes the definition of target diameter and LOS diameter.

[1072] The signal receiving device performs channel estimation based on the transmitted measurement signal X(k) and the measurement signal corresponding received signal Y(k) to obtain channel response (Channel Response) information H(k) = Y(k) / X(k), wherein k = 0, 1, 2, …, K-1 represents the resource unit index. After the terminal obtains the channel response H(k), it is transformed into the first domain, and the target diameter and the LOS diameter are determined in the first domain. The target diameter or the LOS diameter can also refer to a specific sample point in the first domain. Wherein, the LOS diameter can be considered as the first-arriving diameter under normal circumstances (satisfying the LOS condition between the signal transceiver device), and the target diameter refers to the part of the diameter associated with the reflection of the sensing target in signal propagation. The terminal obtains the channel response H(k), and in the process of transforming it into the first domain, it also includes specific preprocessing (such as clutter elimination, smoothing filtering, etc.) of the channel data in the first domain, and then determines the target diameter in the first domain.
