Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority of Chinese Patent Application No. 202110839591.1 filed in China on July 23, 2021, and all the contents of the said application are incorporated herein by reference.

[0002] This application belongs to the field of communications, and particularly relates to a sensing method, device, terminal, and network device.

Background Art

[0003] Future mobile communication systems, such as the novel Beyond 5th Generation (B5G) system or 6th Generation (6G) mobile communication system, not only have communication capabilities but also sensing capabilities. The sensing capabilities, that is, one or more devices with sensing capabilities, can sense information such as the orientation, distance, and speed of target objects through the transmission and reception of wireless signals, or can perform detection, tracking, identification, imaging, etc. on target objects, events, or environments. In the future, as small base stations with high - frequency band large - bandwidth capabilities such as millimeter - wave and terahertz are deployed in 6G networks, the sensing resolution will be significantly improved compared to centimeters, so that the 6G network can provide more refined sensing services.

[0004] The purposes of sensing can be mainly divided into two categories. One purpose is that sensing is used to assist communication or enhance communication performance. For example, a base station can provide a more accurate beam - forming alignment device by tracking the movement trajectory of a device. Another purpose is sensing that has no direct relation to communication. For example, a base station can monitor weather conditions by wireless signals, and a mobile phone can identify a user's gesture, etc. by millimeter - wave wireless sensing.

[0005] The sensing methods can be divided as follows.

[0006] (1) Spontaneous sensing: The device senses by using the reflected signal of its own transmitted signal, such as an echo. The transceiver can be located at the same position and adopt different antennas, and can sense the environmental information around the device, as shown in FIG. 1.

[0007] (2) Passive sensing: The transceiver is located at different positions, and the receiver senses by using the radio signal transmitted by the transmitter. For example, base station A senses the environmental information between base station 1 and base station 2 by receiving the radio signal from base station B, as shown in FIG. 2.

[0008] (3) Interaction sensing: The sensor and the target object agree on the body, time, frequency, format, etc. transmitted by electromagnetic waves through information interaction, and complete the sensing process.

[0009] In the related art, there is no related flow of wireless sensing, thereby making the communication flow incomplete. Summary of the Invention Problems to be Solved by the Invention

[0027] The following clearly describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application.

[0028] Terms such as "first" and "second" in the specification and claims of the present application are used to distinguish similar objects and are not for describing a specific order or sequence. It should be understood that such terms are interchangeable when appropriate, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first" and "second" generally belong to the same category and do not limit the number of objects. For example, the first object may be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the related objects before and after are in an "or" relationship.

[0029] It should be noted that the technology described in the embodiments of this application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.

The following description describes the New Radio (NR) system for illustrative purposes and uses NR terms in most of the following descriptions. However, these technologies may also be applied to applications other than NR system applications, such as the Sixth Generation (6 th Generation, 6G) communication system.

[0030] First, the related technologies related to this application are described as follows.

[0031] The functions and application uses of wireless sensing are as shown in Table 1.

[0032]

Table 1

[0033] By transmitting and receiving / detecting sensing signals, the sensing functions or other sensing requirements in Table 1 can be realized. Here, the device for transmitting and receiving / detecting sensing signals may be the same device or different devices.

[0034] The integrated communication and sensing design is feasible from the following four aspects.

[0035] Both the communication system and the sensing system are based on electromagnetic wave theory, and use the emission and reception of electromagnetic waves to complete the acquisition and transmission of information. Both the communication system and the sensing system are equipped with structures such as antennas, transmitters, receivers, and signal processors, and there is a large overlap in hardware resources. With the development of technology, there is an increasing overlap between the two in the operating frequency band. There are similarities in important technologies such as signal modulation, reception detection, and waveform design.

[0036] The air interface design of the B5G system or 6G system supports wireless communication signals and wireless sensing signals simultaneously, and realizes the integrated design of communication and sensing functions through means of integrated communication and sensing such as signal cooperation design and / or hardware sharing, and while performing information transmission, it has sensing capabilities or provides sensing services.

[0037] The advantages of integrated communication and sensing include cost savings, reducing the device size, reducing the power consumption of the device, improving the spectral efficiency, including some aspects such as reducing the mutual interference between the common senses and improving the system performance.

[0038] Currently, the scope of integrated communication and sensing is not clearly defined. In a broad sense, integrated communication and sensing means the same network provides communication services and sensing services, The same terminal provides communication services and sensing services, The same spectrum provides communication services and sensing services, It includes a plurality of integrated communication and sensing services integrated in the same radio emission, that is, completing the coordinated design of communication signals and sensing signals.

[0039] The schematic diagram of the classification of integrated waveforms of sensing and communication is as shown in Figure 3.

[0040] Hereinafter, with reference to the drawings, the sensing method, apparatus, terminal, and network device according to the embodiments of the present application will be described in detail by means of several embodiments and their application scenarios.

[0041] As shown in Figure 4, the embodiments of the present application provide a sensing method, which includes the following steps.

[0042] Step 401, the terminal determines the measurement amount of the sensing signal. It should be noted that the sensing signal mentioned in the embodiments of the present application is the sensing signal that the terminal needs to measure, and may be, for example, one or several sensing signals.

[0043] Step 402, the terminal detects the sensing signal and obtains a measurement value corresponding to the measurement amount, Here, the sensing signal is transmitted by the first network device.

[0044] It should be noted that the embodiments of this application mainly focus on the base station transmitting a sensing signal, and the terminal receiving, detecting, and obtaining a measurement value of the sensing signal. That is, the first network device mentioned in the embodiments of this application is a base station located on the access network side, and the second network device mentioned in the embodiments of this application may be a mobility and access management function (AMF) entity on the core network side. The second network device may also be a sensing function entity, for example, a sensing network function entity or a sensing network element. This sensing function entity may be located on the core network side or on the access network side. The second network device may also be other function entities on the core network side.

[0045] It should be noted that the terminal may determine the measurement amount of the sensing signal by adopting at least one of the following methods.

[0046] A11. Receive first indication information transmitted by the first network device or the second network device, where the first indication information is used to indicate the measurement amount of the sensing signal that the terminal needs to measure. That is, in such a case, the measurement amount of the sensing signal may be transmitted from the base station to the terminal, or may be transmitted from the AMF or the sensing function entity to the terminal.

[0047] A12. Based on a first sensing requirement, determine the measurement amount of the sensing signal that the terminal needs to measure. That is, in such a case, the measurement amount of the sensing signal is determined by the terminal itself based on the first sensing requirement. Optionally, the first sensing requirement may be transmitted from the first network device or the second network device to the terminal, or may be generated by the terminal.

[0048] Furthermore, it should be further explained that, in order to accurately receive the sensing signal, the terminal needs to first determine the configuration information of the sensing signal before receiving the sensing signal.

[0049] Embodiments of this application provide two ways of transmitting sensing signals. Hereinafter, how the terminal determines the configuration information of the sensing signal in these two ways will be described in detail as follows.

[0050] Method 1: The base station needs to transmit the sensing signal based on the configuration information of the sensing signal. It should be noted that, in such a case, the implementation method for the terminal to determine the configuration information of the sensing signal is B11: The terminal receives the first configuration information of the sensing signal, and the first configuration information is transmitted by the first network device; B12: The terminal receives the second configuration information of the sensing signal, and the second configuration information is transmitted by the second network device; B13: The terminal determines the third configuration information of the sensing signal based on the first sensing requirement, and includes at least one of them.

[0051] Here, it should be explained that the configuration information of the sensing signal may be notified to the terminal only by the base station. In such a case, the first configuration information includes all the configurations of the sensing signal. The configuration information of the sensing signal may also be notified to the terminal only by the AMF entity or the sensing function entity. In such a case, the second configuration information includes all the configurations of the sensing signal. The configuration information of the sensing signal may also be determined only by the terminal itself. In such a case, the third configuration information includes all the configurations of the sensing signal. The configuration information of the sensing signal may further be determined by at least two of the base station, the terminal, and the AMF entity (or the sensing function entity). That is, each device determines only some parameters or some configuration information in the configuration information of the sensing signal.

[0052] For example, when the configuration information of the sensing signal includes three configuration parameters A, B, and C, and the configuration information of the sensing signal is only notified from the base station to the terminal, the first configuration information includes the three configuration parameters A, B, and C of the sensing signal. When the configuration information of the sensing signal is only notified from the AMF entity or the sensing function entity to the terminal, the second configuration information includes the three configuration parameters A, B, and C of the sensing signal. When the configuration information of the sensing signal is only determined by the terminal itself, the third configuration information includes the three configuration parameters A, B, and C of the sensing signal. When the configuration information of the sensing signal is notified from the base station and the AMF to the terminal, the first configuration information includes some of the three configuration parameters A, B, and C of the sensing signal (for example, the first configuration information includes A), and the second configuration information includes the other some of the three configuration parameters A, B, and C of the sensing signal (for example, the first configuration information includes B and C). By analogy in this way, in other cases, it is the same, and this will not be explained further here.

[0053] Hereinafter, in such a case, taking the terminal, the base station, and the sensing function entity as examples, the process before the terminal detects the sensing signal will be described as follows.

[0054] Case 1: The terminal receives the first sensing requirement transmitted by the sensing function entity. The terminal determines the configuration information of the sensing signal based on this first sensing requirement. The base station determines the configuration information of the sensing signal. The terminal receives the first instruction information transmitted by the sensing function entity. The first instruction information is used to indicate the measurement amount of the sensing signal that the terminal needs to measure. The base station transmits the sensing signal according to the configuration information of the sensing signal, and the terminal receives the sensing signal according to the configuration information of the sensing signal.

[0055] Here, what should be explained is that the method for the base station to determine the configuration information of the sensing signal is B111. The first network device receives second configuration information of the sensing signal transmitted by the second network device; B112. The first network device includes one of the following: determining first configuration information of the sensing signal based on third information; Here, the third information B1121. The first sensing requirement; B1122. First recommendation information of the configuration information determined by the second network device based on the first sensing requirement; B1123. At least one of second recommendation information of the configuration information transmitted from the terminal to the first network device.

[0056] Case 2: The terminal receives a first sensing requirement transmitted by the base station. The terminal determines configuration information of the sensing signal based on this first sensing requirement. The base station receives configuration information of the sensing signal transmitted by the sensing function entity. The terminal receives first indication information transmitted by the base station. The first indication information is used to indicate the measurement amount of the sensing signal that the terminal needs to measure. The base station transmits the sensing signal according to the configuration information of the sensing signal, and the terminal receives the sensing signal according to the configuration information of the sensing signal.

[0057] Specifically, the method by which the sensing function entity determines the configuration information of the sensing signal includes determining the configuration information of the sensing signal based on fifth information; Here, the fifth information includes at least one of the following.

[0058] B121. The first sensing requirement.

[0059] B122. Sensing capability information transmitted by the first network device; For example, this sensing capability information may be a capability related to the measurement quantity supported by the first network device. For example, it may be what kind of measurement quantity the terminal supports to acquire. Also, for example, this sensing capability information may be the format information of the sensing signal that the first network device can transmit. For example, the maximum bandwidth of the sensing signal that the first network device can transmit is 100 MHz. This sensing capability information may be reported from the first network device to the second network device.

[0060] B123, which is the sensing capability information transmitted by the terminal, For example, this sensing capability information may be a capability related to the measurement quantity supported by the terminal. For example, it may be what kind of measurement quantity the terminal supports to acquire. Also, for example, this sensing capability may be the format information of the sensing signal that the terminal can detect. For example, the maximum bandwidth of the sensing signal that the terminal can detect is 100 MHz. This sensing capability may be reported from the terminal to the second network device.

[0061] B124, which is the third recommendation information determined based on the first sensing requirement by the first network device for the configuration information and transmitted to the second network device.

[0062] B125, which is the fourth recommendation information determined based on the first sensing requirement by the terminal for the configuration information and transmitted to the second network device.

[0063] B126, which is the fifth recommendation information transmitted from the terminal to the second network device for the configuration information.

[0064] Method 2: The base station broadcasts the sensing signal, and the terminal receives only the sensing signals that need to be measured. It should be noted that in such a case, the implementation method for the terminal to determine the configuration information of the sensing signal is The terminal includes obtaining configuration information of the sensing signal transmitted via broadcast signaling by a first network device.

[0065] It should be noted that in such a case, since the base station broadcasts the sensing signal, the configuration information of the sensing signal is broadcast before the sensing signal is broadcast. In such a case, the terminal needs to know which sensing signals need to be measured based on the configuration information of the sensing signal so that it can accurately receive the sensing signal. Therefore, in another embodiment of the present application, before the terminal obtains the configuration information of the sensing signal transmitted via broadcast signaling by a first network device, The terminal further includes determining a sensing signal to be measured based on the first information, wherein the first information includes at least one of the following.

[0066] B21, a first sensing requirement transmitted by a second network device, It should be noted that in such a case, the first sensing requirement is related to the sensing signal to be measured by the terminal. That is, the first sensing requirement corresponds to the sensing signal to be measured by the terminal, and the terminal can directly determine the sensing signal to be measured based on the first sensing requirement.

[0067] B22, sensing signal index information that the terminal needs to measure and is transmitted by a second network device, The sensing signal here is a public sensing signal.

[0068] It should be noted that since the base station transmits a plurality of public sensing signals, this sensing signal index information is used to specifically indicate which or which public sensing signals they are. For example, when the sensing signal index information is 1, the terminal needs to measure the public sensing signal whose number or index is 1.

[0069] Hereinafter, in such a case, taking the terminal, base station, and sensing function entity as examples, the process before the terminal detects the sensing signal will be described as follows.

[0070] Case 1: The terminal receives the first sensing requirement transmitted by the sensing function entity. Based on this first sensing requirement, the terminal determines the sensing signal to be measured. The terminal receives the configuration information of the sensing signal to be measured broadcast by the base station. The base station determines the configuration information of the sensing signal based on the first sensing requirement. The terminal receives the first instruction information transmitted by the sensing function entity. The first instruction information is used to indicate the measurement amount of the sensing signal that the terminal needs to measure. The base station transmits the sensing signal according to the configuration information of the sensing signal, and the terminal receives the sensing signal according to the sensing signal to be measured and the configuration information of the sensing signal.

[0071] Case 2: The terminal receives the first sensing requirement transmitted by the sensing function entity and the sensing signal index information that the terminal needs to measure, determines the sensing signal to be measured, and the terminal receives the configuration information of the sensing signal to be measured broadcast by the base station. The base station determines the configuration information of the sensing signal based on the first sensing requirement. The terminal receives the first instruction information transmitted by the base station. The first instruction information is used to indicate the measurement amount of the sensing signal that the terminal needs to measure. The base station transmits the sensing signal according to the configuration information of the sensing signal, and the terminal receives the sensing signal according to the sensing signal to be measured and the configuration information of the sensing signal.

[0072] Furthermore, it should be further explained that before transmitting information to the terminal, both the base station and the core network need to first determine the terminal that can receive the information. Specifically, the base station and the core network determine the terminal (i.e., the terminal participating in sensing) that receives the information based on one of the following pieces of information.

[0073] B31: Information on whether the terminal accesses the first network device. This information indicates whether the terminal can access the associated base station.

[0074] B32 is the sensing ability reported by the terminal, For example, this sensing ability may be related to the measurement quantities supported by the terminal, such as what types of measurement quantities the terminal supports for acquisition. Also, for example, this sensing ability may be the format information of the sensing signal that the terminal can detect. For example, the maximum bandwidth of the sensing signal that the terminal can detect is 100 MHz. This sensing ability may be reported from the terminal to the first network device or to the second network device.

[0075] B33 is other a priori information including terminal location information, For example, for 3 - dimension (3D) environment mapping, only the user equipment (UE) within the environment range waiting for reconstruction needs to participate.

[0076] Here, further to be explained, after determining the UEs participating in sensing, based on related information of the sensing measurement signals reported by the UEs, such as measurement quantities like received signal strength indicator (RSSI), reference signal receiving power (RSRP), and mobility, the base station can further screen the UEs.

[0077] Furthermore, to be further explained, the first sensing requirement in the embodiments of this application is related to at least one of the following.

[0078] C11 is the sensing target, Optionally, the sensing target includes at least one of, but is not limited to, an object, a device, a person, an animal, a building, a vehicle, an environment, air quality, humidity, temperature, and a specific area (i.e., a certain area).

[0079] C12 is a sensed quantity, Optionally, the sensed quantity includes, but is not limited to, at least one of the position of the sensed object, the distance to the sensed object, the moving speed of the sensed object, the imaging of the sensed object, the movement trajectory of the sensed object, the analysis of the quality of the sensed object, and the analysis of the material.

[0080] C13 is a sensing index, Optionally, the sensing index includes, but is not limited to, at least one of sensing accuracy, sensing error, sensing range, sensing delay, detection probability, and false alarm probability. Specifically, this sensing accuracy includes distance resolution, imaging resolution, moving speed resolution, or angular resolution, and this sensing error includes distance error, imaging error, or moving speed error.

[0081] It should be noted that the first sensing requirement is simultaneously related to the combination of the sensed object and the sensed quantity, and can generate the following sensing requirements.

[0082] Feature information of the target object: the presence, distance, position, speed, acceleration, material, shape, type, Radar Cross Section (RCS), polarization scattering characteristics, etc. of the target object Relevant information of the target event: fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip recognition, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, etc. Relevant information of the target environment: humidity, luminance, temperature and humidity, atmospheric pressure, air quality, weather conditions, terrain and landform, building / vegetation distribution, number statistics, pedestrian density, vehicle density, etc. Optionally, the first sensing requirement may further be related to the composition information of the sensing signal or the measured quantity of the sensing signal.

[0083] As shown in Table 2, the first sensing requirement may be divided into several sensing classifications, and each sensing classification is related to at least one of the configuration information of the sensing signal and the measured quantity of the sensing signal. The relevant relationship may be agreed upon by a protocol or notified by signaling between different devices. If a device has a sensing requirement, for example, if this sensing requirement is that another device (e.g., a terminal) needs to measure and feedback the measured quantity related to the environment reconstruction, this sensing requirement is the sensing index 1. Optionally, the terminal device obtains the sensing index 1 by receiving the signaling transmitted by another device, and determines the configuration information of the sensing signal and / or the measured quantity of the sensing signal based on the sensing index 1 and Table 2.

[0086] D11. The terminal transmits the measured quantity and the measured value corresponding to the measured quantity to the first network device or the second network device. Optionally, when the measured quantity and the measured value corresponding to the measured quantity are transmitted to the first network device, the first network device may transmit the measured quantity and the measured value corresponding to the measured quantity to the second network device. The second network device performs conversion of the sensing result and transmits the sensing result to the terminal (corresponding to the case where the terminal starts the sensing service) or the third network device (corresponding to the case where other devices other than the terminal start the sensing service). Specifically, this third network device may be another base station, that is, a base station other than the measured sensing signal, other network elements in the core network, such as an application server (in this case, corresponding to the case where a third-party application starts the sensing service), a network management system, etc.

[0087] Optionally, when the measurement quantity and the measurement value corresponding to the measurement quantity are transmitted to the first network device, the first network device may convert them into a sensing result based on the measurement quantity and the measurement value corresponding to the measurement quantity, and transmit the sensing result to the second network device, and the second network device may directly transmit the sensing result to the terminal or the third network device.

[0088] Optionally, when the measurement quantity and the measurement value corresponding to the measurement quantity are transmitted to the second network device, the second network device performs conversion of the sensing result and transmits the sensing result to the terminal or the third network device.

[0089] Optionally, when the terminal is the start end of the sensing service, the terminal may further receive the sensing result from the second network device side.

[0090] D12. The terminal determines a sensing result based on the measurement quantity and the measurement value corresponding to the measurement quantity. Optionally, then, the terminal may transmit the sensing result to the first network device.

[0091] Optionally, the measurement quantity and the measurement value corresponding to the measurement quantity are the sensing result.

[0092] When the terminal transmits the sensing result to the first network device, the first network device transmits the sensing result to the second network device, and the second network device transmits the sensing result to the third network device.

[0093] Hereinafter, taking the perspective of the sensing service start end as an example, the operations that need to be performed after the terminal obtains the measurement value are exemplified as follows.

[0094] When a third-party application starts a sensing service, optionally, after obtaining the measurement values, the terminal transmits the measurement quantity and the measurement values corresponding to the measurement quantity to the base station, and then the base station transmits the measurement quantity and the measurement values corresponding to the measurement quantity to the sensing function entity.

Optionally, after obtaining the measurement values, the terminal transmits the measurement quantity and the measurement values corresponding to the measurement quantity to the base station, and the base station determines a sensing result based on the measurement values and transmits it to the sensing function entity. The sensing function entity transmits the sensing result to the application server, and the application server may transmit the sensing result to the third-party application. Optionally, after obtaining the measurement values, the terminal determines a sensing result based on the measurement quantity and the measurement values corresponding to the measurement quantity, transmits the sensing result to the base station, and the base station forwards the sensing result to the sensing function entity. The sensing function entity transmits the sensing result to the application server, and the application server may transmit the sensing result to the third-party application.

[0102] Furthermore, it should be noted that this sensing function entity may be located on the core network side or the base station side. When the sensing function entity is located on the base station side, all flows of the sensing service are completed in the Radio Access Network (RAN) (for the case where the base station triggers the sensing service or the UE triggers the sensing service). This sensing function entity may be an individual functional entity / physical entity, or may be deployed on a general-purpose server of the core network as one of the core network functions, or may be deployed on the base station side as one of the base station functions. This sensing function entity directly interacts with the application server (such as the operator's application server) regarding the sensing request and sensing result, or the sensing function entity and the AMF interact regarding the sensing request and sensing result, and the AMF (Gateway Mobile Location Centre (GMLC) and Network Exposure Function (NEF)) may directly or indirectly interact with the application server (such as a third-party application server) regarding the sensing request and sensing result.

[0103] It should be noted that the configuration information of the sensing signal in the embodiments of this application includes at least one of the following parameters.

[0104] H101, which is the waveform of the sensing signal, For example, Orthogonal Frequency Division Multiplex (OFDM), Single-carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), pulse signal, etc.

[0105] H102 is the subcarrier interval of the sensing signal, For example, it is 30 KHz, the subcarrier interval of an OFDM system.

[0106] H103 is the guard interval of the sensing signal, It should be noted that this guard interval is the time interval from the signal end transmission time to the time when the latest echo signal of this signal is received. This parameter is proportional to the maximum sensing distance and may be calculated by, for example, 2dmax / c, where dmax is the maximum sensing distance (belonging to the sensing requirement). For example, for the sensing signal transmitted and received by itself, dmax represents the maximum distance from the transmission and reception point of the sensing signal to the signal emission point. In some cases, the OFDM signal cyclic prefix (CP) can play the role of the minimum guard interval.

[0107] H104 is the bandwidth of the sensing signal, It should be noted that this parameter is inversely proportional to the distance resolution and may be obtained by c / (2×delta_d). Here, delta_d is the distance resolution (belonging to the sensing requirement), and c is the speed of light.

[0108] H105 is the burst duration of the sensing signal, It should be noted that the burst duration is inversely proportional to the rate resolution (belonging to the sensing requirement). It is the time width of the sensing signal and is mainly used to calculate the Doppler frequency offset. This parameter may be calculated by c / (2×delta_v×fc), where delta_v is the speed resolution and fc is the carrier frequency of the sensing signal.

[0109] H106 is the time domain interval of the sensing signal, It should be noted that this time domain interval may be calculated by c / (2×fc×v_range). Here, v_range is the result of subtracting the minimum speed from the maximum rate (belonging to the sensing requirement), and this parameter is the time interval between two adjacent sensing signals.

[0113] H110, which is the time resource of the sensing signal, For example, this time resource may be the slot index or symbol index of the slot where the sensing signal is located. Here, the time resource is divided into two types. One is the primary time resource. For example, one symbol transmits a first signal in all directions, and the other is the non-primary time resource, such as a plurality of sets of periodic time resources or discontinuous time resources (which may include a start time and an end time). Each periodic time resource transmits sensing signals in the same direction, and the beam directions on different groups of periodic time resources are different.

[0114] H111, which is the frequency resource of the sensing signal, Optionally, this frequency resource includes the center frequency point of the sensing signal, bandwidth, resource block (RB) or subcarrier, reference point A (Point A), starting bandwidth position, etc.

[0116] It should be noted that the measured quantity in the embodiments of this application includes at least one of the following.

[0117] K11, which is the first type of measured quantity, Specifically, the first type of measured quantity is K111, the channel matrix H, K112, the received signal strength indication (RSSI), K113, the reference signal received power (RSRP), K114, the channel state information (CSI), K115, the power of each path in the multipath channel, K116, the delay of each path in the multipath channel, K117, the angle information of each path in the multipath channel, K118, the Doppler spread, K119, the Doppler shift, K120, the phase difference between the sensing signal received by the first antenna and the sensing signal received by the second antenna, K121, the delay difference between the sensing signal received by the first antenna and the sensing signal received by the second antenna, including at least one of the differences in characteristics between the I-branch signal and the Q-branch signal It should be noted that the difference in characteristics may be a phase difference or other differences between the I-branch signal and the Q-branch signal.

[0118] Here, it should be noted that the I-branch signal and the Q-branch signal are a in-phase signal and a quadrature signal respectively, I is in-phase, Q is quadrature, and the phases of the I-branch signal and the Q-branch signal differ by 90 degrees.

[0119] K12 is a second type of measurement quantity Specifically, the second type of measurement quantity includes at least one of the following K121 is the characteristic information of the target object It should be noted that the characteristic information of the target object is information that can reflect the attributes or states of the target object, and may be at least one of the existence of the target object, the distance of the target object, the position of the target object, the speed of the target object, the acceleration of the target object, the material of the target object, the shape of the target object, the type of the target object, the Radar Cross Section (RCS) of the target object, the polarization scattering characteristics, etc. K122 is the related information of the target event It should be noted that the related information of the target event is information related to the target event, that is, information that can be detected / perceived when the target event occurs, and may be at least one of fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip recognition, gait recognition, facial expression recognition, respiration monitoring, heartbeat monitoring, etc. K123 is the related information of the target environment It should be noted that the related information of the target environment may be at least one of humidity, luminance, temperature humidity, atmospheric pressure, air quality, weather conditions, terrain and landform, building / vegetation distribution, number statistics, crowd density, vehicle density, etc.

[0121] Optionally, the measured quantity is the measured quantity for each antenna or the measured quantity for each sensing resource.

[0122] For example, the measured quantity is the measured quantity of each antenna (port) at the transmitting end or the receiving end, or the measured quantity on each sensing resource, such as the measured quantity of each resource block (Resource Block, RB), sub-carrier, or RB group.

[0123] It should be noted that when the core network transmits sensing-related information to the base station, the core network or the sensing network function entity / sensing network element determines which base station the relevant base station is based on the target area, and determines the direction in which this base station transmits the sensing signal.

[0124] Hereinafter, the following will be described by taking the specific application situation of the actual application as an example.

[0125] Specific application situation 1: Base station A transmits a sensing signal, UE receives the sensing signal, and a third-party application starts a sensing service.

[0126] The network devices involved in such a case are as shown in FIG. 5. The realization process in such a case is mainly as follows.

[0127] Step S101, the application server receives the sensing requirement of the third-party application, For example, the sensing requirement is a 3D map of the sensed target area (the accuracy / resolution of the map is 5 m), and this target area may be a specified area, for example, the perimeter of a building or the surrounding area of the target UE. The sensing requirement may include information about the target area, such as area longitude and latitude (range), etc. Step S102: The application server (such as an in-network server, for example, an Intranet Management System (including IMS) or an extranet server) sends the sensing requirement to the core network (such as AMF) or the sensing network function entity / sensing network element (if it exists). Alternatively, the application server sends the sensing requirement to AMF, and AMF forwards this requirement to the sensing network function entity / sensing network element. It should be noted here that the sensing network function entity / sensing network element performs target information interaction (the target information includes processed sensing requests, interaction sensing capabilities, interaction sensing auxiliary data, interaction sensing measurement quantities, or sensing results) with the target UE, or the serving base station of the target UE, or the base station related to the target area to obtain the target sensing result or sensing measurement quantity (uplink measurement quantity or downlink measurement quantity). Based on the target area, it may obtain base station information that may require information interaction by interacting with other network elements / functions in the core network.

[0128] Further to be explained is that the core network (or the sensing network function entity / sensing network element) or the application server or other nodes (e.g., AMF) complete the supervision and management flow. If the AMF transfers this requirement to the sensing network function entity / sensing network element, and a plurality of sensing network function entities / sensing network elements may correspond to one AMF, there is a problem of selecting a sensing network function entity / sensing network element (selected by the AMF), The factors that the AMF considers when selecting a sensing network function entity / sensing network element include at least one of the required QoS (e.g., sensing accuracy, response time, sensing QoS level), access type (Third Generation Partnership Projects (3GPP) access / non-3GPP access), the 5th-Generation (5G) access network (AN) type of the target UE (i.e., 5G NR or eLTE) and the serving AN node (i.e., gNodeB or NG-eNodeB), RAN configuration information, the capabilities of the sensing network function entity / sensing network element, the load of the sensing network function entity / sensing network element, the location of the sensing network function entity / sensing network element, the indication of single event reporting or multiple event reporting, the event reporting duration, network slice information, etc.

[0129] Step S103, the core network (or the sensing network function entity / sensing network element) transmits the sensing requirement or the configuration information of the sensing signal to base station A. Further to be explained is that the configuration information of the sensing signal may be related to the sensing requirement, and only the notification of the sensing requirement is needed. The receiving end determines the configuration information of the sensing signal based on the relevant relationship with the sensing requirement. Optionally, the method of determining the configuration information of the sensing signal based on the sensing requirement (for example, determining the bandwidth size of the sensing signal based on the sensing resolution requirement) may adopt at least one of the following multiple methods.

[0130] Y11. The base station A reports its sensing capabilities (capabilities related to transmitting sensing signals, such as the maximum bandwidth for transmitting sensing signals, the maximum transmission power of sensing signals, etc.) to the core network, and / or the UE reports its sensing capabilities (capabilities related to receiving sensing signals, such as the maximum bandwidth of sensing signals that can be received, the measurement quantities of supported sensing signals, etc.) to the core network (AMF or sensing network function entity / sensing network element). After that, the core network determines the configuration information of the sensing signal based on the sensing requirement. Y12. The base station determines the configuration information of the sensing signal based on the sensing requirement. Y13. The core network recommends the configuration information of the sensing signal to the base station based on the sensing requirement, and the base station finally determines the configuration information of the sensing signal. Y14. The base station recommends the configuration information of the sensing signal to the core network based on the sensing requirement, and the core network finally determines the configuration information of the sensing signal. Y15. The UE transmits the proposed configuration information of the sensing signal to the base station, and the base station determines the configuration information of the sensing signal. Y16. The UE transmits the proposed configuration information of the sensing signal to the core network, and the core network determines the configuration information of the sensing signal. Y17. At least two of the three parties, namely the core network, the base station, and the UE, respectively determine a part of the configuration information of the sensing signal.

[0131] Here, it should be noted that the core network or the sensing network function entity / sensing network element, which is the determination method of base station A, determines that the relevant base station is base station A based on the target area and determines the direction in which base station A transmits the sensing signal.

[0132] Step S104, the core network (or the sensing network function entity / sensing network element) or base station A transmits the configuration information of the sensing signal (including time-frequency information, sequence information, etc.) or the sensing requirement to the UE, The base station determines the UE that participates in sensing (i.e., receives the sensing signal), or the AMF / sensing network function entity / sensing network element determines the UE that participates in sensing. Specifically, for the method of determining the UE that participates in sensing, reference may be made to the above description, and no further explanation will be given here.

[0133] It should be noted that after determining the UE that participates in sensing, based on the related information of the sensing measurement signal reported by the UE, such as measurement quantities such as RSSI, RSRP, and mobility, the base station can further screen the UE.

[0134] Step S105, the core network (or the sensing network function entity / sensing network element) or base station A transmits the measurement quantities related to the sensing signal that the UE needs to measure (such as Angle-of-Arrival (AOA), Angle of Departure (AOD), delay, RSRP, radar spectrum information, etc.) to the UE, or, The measurement quantities are determined by the UE based on the sensing requirement, and individual signaling instructions (the mapping table from the sensing requirement to the measurement quantities) are not required.

[0135] Step S106, base station A transmits the sensing signal, It should be noted that base station A transmits the sensing signal in the way of beam sweeping.

[0136] Step S107, the UE receives the sensing signal.

[0137] After receiving the sensing signal, the UE obtains the measured value of the corresponding measurement quantity, and may select one of the following processing methods for this measured value.

[0138] In processing method 1, the conversion from the measurement quantity to the sensing result is completed in the core network or the application server.

[0139] Step S108: The UE sends the measurement quantity to base station A, and base station A sends the measurement quantity to the core network (or the sensing network function entity / sensing network element). Step S109: The core network (or the sensing network function entity / sensing network element) sends the measurement quantity to the application server, and the application server determines the sensing result based on the measurement quantity, or The core network (or the sensing network function entity / sensing network element) determines the sensing result based on the measurement quantity, and sends the sensing result to the application server. Step S110: The application server sends the sensing result to a third-party application.

[0140] In processing method 2, the conversion from the measurement quantity to the sensing result is completed at the base station.

[0141] Step S108: The UE sends the measurement quantity to base station A. Step S109: Base station A determines the sensing result based on the measurement quantity, and sends the measurement result to the core network (or the sensing network function entity / sensing network element). Step S110: The core network (or the sensing network function entity / sensing network element) sends the sensing result to the application server. Step S111: The application server sends the sensing result to a third-party application.

[0142] It should be noted that in such a processing method, the conversion from the measurement quantity (such as angle information, RSRP information, etc.) to the sensing result (such as a 3D map) is at base station A.

[0143] For processing method 3, the conversion from the measurement amount to the sensing result is completed at the UE.

[0144] In step S108, the UE determines the sensing result based on the measurement amount. In step S109, the UE sends the sensing result to base station A, and base station A sends the sensing result to the core network (or the sensing network function entity / sensing network element). In step S110, the core network (or the sensing network function entity / sensing network element) sends the sensing result to the application server. In step S111, the application server sends the sensing result to the third-party application.

[0145] Furthermore, it should be noted that the relevant information of base station A, such as the antenna position, synchronization information (SFN start time), AI-related information, etc., needs to be sent to the node that completes the above conversion to assist in the completion of the conversion process.

[0146] Furthermore, it should be noted that the charging function is completed at the core network or the application server.

[0147] Furthermore, it should be further explained that the sensing signal in the above flow may be transmitted by a plurality of base stations / transmission reception points (TRPs), and the received sensing signal may be a plurality of UEs. At this time, the core network determines a set of base stations that transmit the sensing signal and a set of base stations that receive the sensing signal, and transmits the configuration information of the sensing signals of the plurality of base stations to the corresponding plurality of base stations and the plurality of UEs respectively, and needs to transmit the measurement quantities related to the sensing signals that the receiving base stations need to measure to the corresponding plurality of UEs respectively. Optionally, it is necessary to interact the configuration information of the sensing signal among the plurality of transmitting base stations (for example, the base station acting as a coordinator transmits the configuration information of the sensing signal to other transmitting base stations and transmits the measurement quantities related to the sensing signal to the UE), and accordingly, the base station A in the above flow may be TRP A.

[0148] Furthermore, it should be further explained that after the UE receives the sensing requirement or the measurement quantity related to sensing transmitted by the first network device or the second network device, the UE may reject this sensing requirement or agree to this sensing requirement.

[0149] In a specific application scenario 2, the base station A transmits a sensing signal, the UE receives the sensing signal, and the core network (or network management system, or base station) starts a sensing service.

[0150] The realization process in such a case is mainly as follows.

[0151] Step S201, the core network AMF transmits the sensing requirement or the configuration information of the sensing signal to the sensing network function entity / sensing network element. For example, the sensing requirement is a 3D map of the sensed target area (the accuracy / resolution of the map is 5 m), and this target area may be a specified area, for example, the perimeter of a building, or the surrounding area of the target UE. The sensing requirement may include information about the target area, such as area longitude and latitude (range), etc.

[0152] Alternatively, the AMF receives the configuration information of the sensing requirement or sensing signal transmitted by the network management system and forwards it to the sensing network function entity / sensing network element. Alternatively, the AMF receives the configuration information of the sensing requirement or sensing signal transmitted by the base station and forwards it to the sensing network function entity / sensing network element (Note: The configuration information of the sensing requirement or sensing signal of base station A may not be transmitted to the core network and may be directly transmitted to base station B).

[0153] Step S202: The sensing network function entity / sensing network element (the characteristics of this sensing network function entity / sensing network element are the same as those described in the specific application scenario 1) transmits the configuration information of the sensing requirement or sensing signal to base station A (or the AMF transmits the configuration information of the sensing requirement or sensing signal to base station A). It should be further noted that the configuration information of the sensing signal may be related to the sensing requirement, and only the notification of the sensing requirement is needed. The receiving end determines the configuration information of the sensing signal based on the relationship with the sensing requirement. Optionally, the specific implementation method of determining the configuration information of the sensing signal based on the sensing requirement (for example, determining the bandwidth size of the sensing signal based on the sensing resolution requirement) is the same as that in the specific application scenario 1 and will not be further described here.

[0154] Here, both the configuration information of the sensing signal and the measured quantity of the sensing signal are the same as those in the specific application scenario 1.

[0155] Step S203: The core network (or the sensing network function entity / sensing network element) or base station A transmits the configuration information of the sensing signal (including time-frequency information, sequence information, etc.) or the sensing requirement to the UE (receiving base station). Optionally, the method for the core network or the base station to determine the UE participating in sensing may refer to the above description and will not be elaborated here further.

[0156] Step S204: The core network (or the sensing network function entity / sensing network element) or base station A transmits the measurement quantity related to the sensing signal (such as AOA, AOD, delay, RSRP, radar spectrum information, etc.) to the UE, or The measurement quantity is determined by the UE based on the sensing requirement, and an individual signaling instruction (mapping table from the sensing requirement to the measurement quantity) is not required.

[0157] Step S205: Base station A transmits the sensing signal, It should be noted that base station A transmits the sensing signal in the way of beam sweeping.

[0158] Step S206: The UE receives the sensing signal, After receiving the sensing signal, the UE obtains the measured value of the corresponding measurement quantity, and may select one of the following processing methods for this measured value.

[0159] Processing method 1: The conversion from the measurement quantity to the sensing result is completed by the core network.

[0160] Step S207: The UE transmits the measurement quantity to base station A, Step S208: Base station A transmits the measurement quantity to the core network (AMF or sensing network function entity / sensing network element), Step S209: The core network (AMF or sensing network function entity / sensing network element) converts the measurement quantity into the sensing result.

[0161] In processing method 2, the conversion from the measurement quantity to the sensing result is completed at the base station.

[0162] Step S207: The UE transmits the measurement quantity to base station A. Step S208: Base station A determines the sensing result based on the measurement quantity. Step S209: Base station A transmits the sensing result to the core network (AMF or sensing network function entity / sensing network element).

[0163] It should be further noted that after the UE receives the sensing requirement or the measurement quantity related to sensing transmitted by the first network device or the second network device, the UE may reject this sensing requirement or agree to this sensing requirement.

[0164] In processing method 3, the conversion from the measurement quantity to the sensing result is completed at the UE.

[0165] Step S207: The UE determines the sensing result based on the measurement quantity. Step S208: The UE transmits the sensing result to base station A. Step S209: Base station A transmits the sensing result to the core network (or sensing network function entity / sensing network element).

[0166] Here, it should be noted that when the sensing network function entity / sensing network element is deployed at the base station, one optional solution is that the entire sensing service may not need to pass through the core network.

[0167] Furthermore, it should be further noted that the sensing signals in the above flow may be transmitted by a plurality of base stations / TRPs, and the received sensing signals may be a plurality of UEs. At this time, the core network determines a set of base stations that transmit sensing signals and a set of base stations that receive sensing signals, and transmits the configuration information of the sensing signals of the plurality of base stations to the corresponding plurality of base stations and the plurality of UEs respectively, and needs to transmit the measurement quantities related to the sensing signals that the receiving base station needs to measure to the corresponding plurality of UEs respectively. Optionally, it is necessary to interact the configuration information of the sensing signals among the plurality of transmitting base stations (for example, the base station acting as a coordinator transmits the configuration information of the sensing signals to other transmitting base stations and transmits the measurement quantities related to the sensing signals to the UEs). Accordingly, base station A in the above flow may be TRP A.

[0168] Specific application scenario 3: Base station A transmits a sensing signal, the UE receives the sensing signal, and the UE starts a sensing service.

[0169] The realization process in such a case is mainly as follows.

[0170] Step S301: The UE transmits the sensing requirement or the configuration information of the sensing signal to the AMF by NAS signaling. For example, the sensing requirement is a 3D map of the sensing target area (the accuracy / resolution of the map is 5 m). This target area may be a specified area, such as the perimeter of a certain building, or the surrounding area of the target UE. The sensing requirement may include information about the target area, such as area longitude and latitude (range), etc.

[0171] Step S302: The AMF transmits the sensing requirement or the configuration information of the sensing signal to the sensing network function entity / sensing network element. Step S303: The sensing network function entity / sensing network element (the features of this sensing network function entity / sensing network element are the same as those described in the specific application scenario 1) transmits the sensing requirement or the composition information of the sensing signal to base station A (or the AMF transmits the sensing requirement or the composition information of the sensing signal to base station A). It should be further noted that the composition information of the sensing signal may be related to the sensing requirement, and only the notification of the sensing requirement is necessary. The receiving end determines the composition information of the sensing signal based on the relationship with the sensing requirement. Optionally, the method of determining the composition information of the sensing signal based on the sensing requirement (for example, determining the bandwidth size of the sensing signal based on the sensing resolution requirement) includes at least one of multiple methods.

[0172] Y21: Base station A reports its sensing capabilities (related capabilities for transmitting sensing signals, such as the maximum bandwidth for transmitting sensing signals, the maximum transmission power of sensing signals, etc.) to the core network (AMF or sensing network function entity / sensing network element), and / or the UE reports its sensing capabilities (related capabilities for receiving sensing signals, such as the maximum bandwidth of sensing signals that can be received, the measurement quantities of supported sensing signals, etc.) to the core network. Then, the core network determines the composition information of the sensing signal based on the sensing requirement. Y22: The base station determines the composition information of the sensing signal based on the sensing requirement. Y23: The core network determines the composition information of some sensing signals, and the base station determines the composition information of other parts of the sensing signals. Y24: The core network recommends the composition information of the sensing signal to the base station based on the sensing requirement, and the base station finally determines the composition information of the sensing signal. Y25: The base station recommends the composition information of the sensing signal to the core network based on the sensing requirement, and the core network finally determines the composition information of the sensing signal. Y26: The UE recommends the composition information of the sensing signal to the base station based on the sensing requirement, and the base station finally determines the composition information of the sensing signal. Y27. The UE recommends the configuration information of the sensing signal to the core network based on the sensing requirement, and the core network finally determines the configuration information of the sensing signal. Y28. The UE determines the configuration information of the sensing signal based on the sensing requirement.

[0173] Step S304.

At this time, the core network determines a set of base stations that transmit the sensing signals and a set of base stations that receive the sensing signals, and transmits the configuration information of the sensing signals of the plurality of base stations to the corresponding plurality of base stations and the plurality of UEs respectively, and it is necessary to transmit the measurement quantities related to the sensing signals that the receiving base station needs to measure to the corresponding plurality of UEs respectively. Optionally, it is necessary to interact the configuration information of the sensing signals among the plurality of transmitting base stations (for example, the base station acting as a coordinator transmits the configuration information of the sensing signals to other transmitting base stations and transmits the measurement quantities related to the sensing signals to the UEs), and accordingly, base station A in the above flow may be TRP A.

[0183] Furthermore, it should be further explained that after the UE receives the sensing requirement or the measurement quantity related to sensing transmitted by the first network device or the second network device, the UE may reject this sensing requirement or agree to this sensing requirement.

[0204] Step S502: The sensing network function entity / sensing network element sends the configuration information of the sensing requirement or sensing signal to base station A (or the AMF sends the configuration information of the sensing requirement or sensing signal to base station A). Or the configuration information of the sensing signal is related to the sensing requirement, and only a notification of the sensing requirement is needed. The receiving end determines the configuration information of the sensing signal based on the associated relationship with the sensing requirement. The method of determining the configuration information of the sensing signal based on the sensing requirement refers to the above description and will not be further explained here.

[0205] Step S503: The core network (or the sensing network function entity / sensing network element) sends the sensing requirement or the sensing signal index information that the UE needs to measure to the UE. Alternatively, the sensing signal index information is related to the sensing requirement, and only the notification of the sensing requirement is needed.

The base station determines the UEs that participate in sensing (i.e., receive sensing signals), or the AMF / Sensing Network Function Entity / Sensing Network Element determines the UEs that participate in sensing. Optionally, the method for determining the UEs that participate in sensing refers to the above description and will not be further elaborated here.

[0206] Step S504, the core network (or the sensing network function entity / sensing network element) sends to the UE the measurement quantities (such as AOA, AOD, delay, RSRP, radar spectrum information, etc.) related to the sensing signals that the UE needs to report, or The measurement quantities are determined by the UE based on the sensing requirement, and individual signaling instructions (the mapping table from the sensing requirement to the measurement quantities) are not required.

[0207] Step S505, base station A transmits the sensing signals (broadcasts the sensing signals). It should be noted that base station A transmits the sensing signals in the manner of beam sweeping.

[0208] Step S506, the UE receives the sensing signals. Furthermore, it should be noted that before the UE receives the sensing signals, the UE reads the broadcast signaling to obtain the configuration information of the sensing signals.
