Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority of Chinese Patent Application No. 202110839586.0 filed in China on July 23, 2021, and all of its content is incorporated herein by reference. This application belongs to the field of communications, and particularly relates to a sensing method, apparatus, and network device.

Background Art

[0002] For example, future mobile communication systems such as B5G systems or 6G systems will, in addition to having communication capabilities, also have sensing capabilities. The sensing ability means that one or more devices equipped with sensing capabilities can sense information such as the orientation, distance, speed, etc. of a target object through the transmission and reception of wireless signals, or can perform detection, tracking, recognition, imaging, etc. on the target object, event, or environment, etc. In the future, with the deployment of small base stations with high - frequency bands such as millimeter - wave and terahertz and wide - bandwidth capabilities in 6G networks, the sensing resolution will be significantly higher compared to the case of centimeter - wave, so that the 6G network can provide more refined sensing services.

[0003] The purposes of sensing are generally classified into two categories. The first is to use sensing for communication assistance or communication performance enhancement. For example, a base station can provide a more accurate beamforming alignment device by tracking the movement trajectory of a device. The other is sensing that has no direct relation to communication, such as a base station monitoring weather conditions by wireless signals and a mobile phone recognizing a user's gesture by millimeter - wave wireless sensing.

[0004] Sensing methods can be divided into the following several methods. (1) Active sensing: As shown in FIG. 1, a device uses the reflected signal of its own transmitted signal, such as an echo, for sensing. The transmitter and receiver are at the same position, and different antennas can be adopted to sense the environmental information around the device. (2) Passive sensing: As shown in Figure 2, the transceiver is located in different positions, and the receiver senses using the radio signal transmitted by the transmitter. For example, base station 1 senses environmental information between base station 1 and base station 2 by receiving the radio signal from base station 2. (3) Interactive sensing: The sensing process is completed by exchanging information between the senser and the target object to define the source, time, frequency, format, etc., of the electromagnetic wave transmission.

[0022] Next, we will explain the related technologies concerning this application as follows.

[0023] Table 1 shows the functions and applications of wireless sensing.

[0024] [Table 1]

[0025] The sensing functions or other sensing requirements listed in Table 1 can be realized by transmitting and receiving / detecting sensing signals. The devices that transmit and receive / detect sensing signals may be the same device or different devices.

[0026] Integrated communication sensing design is feasible from the following four perspectives. Both communication and sensing systems are based on electromagnetic wave theory, and information acquisition and transmission are completed through the transmission and reception of electromagnetic waves. Both communication systems and sensing systems consist of components such as antennas, transmitters, receivers, and signal processors, resulting in a significant overlap in hardware resources. As technology advances, the operating frequency bands of both tend to overlap considerably. There are similarities in key technologies such as signal modulation, reception detection, and waveform design.

[0027] The air interface design of a B5G or 6G system simultaneously supports wireless communication signals and wireless sensing signals, and realizes an integrated communication sensing function design through signal linkage design and / or hardware sharing, thereby transmitting information while simultaneously possessing sensing capabilities or providing sensing services.

[0028] The advantages of integrating communication and sensing are: Cost savings, Miniaturization of equipment, Reduced power consumption of equipment, Improvement of spectral efficiency, This includes reducing mutual interference between communication sensors and improving system performance.

[0029] Currently, the scope of integrated communication sensing is not clearly defined, and in a broad sense, integrated communication sensing is... Providing communication services and sensing services through the same network, Providing communication services and sensing services using the same terminal, To provide communication services and sensing services on the same frequency spectrum, This includes completing the integrated communication and sensing service with a single wireless transmission, i.e., designing the coordination between communication signals and sensing signals.

[0030] A schematic diagram of the integrated waveform classification for sensing and communication is shown in Figure 3.

[0031] The sensing methods, apparatus, and network equipment provided in the embodiments of this application will be described in detail below with reference to the drawings, through several embodiments and their use cases.

[0032] As shown in Figure 4, an embodiment of the present application is Step 401, in which the first network device transmits a sensing signal, The present invention provides a sensing method which includes step 402, in which a first network device detects an echo of the sensing signal based on the measured amount of the sensing signal and obtains a measured value corresponding to the measured amount.

[0033] It should be explained that the embodiments of this application mainly describe a case in which a base station transmits a sensing signal, and the base station receives and detects the sensing signal to obtain a measurement value. In other words, the first network device described in the embodiments of this application is a base station on the access network side, and the second network device described in the embodiments of this application may be an Access and Mobility Management Function (AMF) entity on the core network side, and the second network device may also be a sensing function entity, for example, it may be called a sensing network function entity or a sensing network element, and the sensing function entity may be on the core network side or the access network side, and the second network device may be another functional entity on the core network side.

[0034] It should be explained that the first network device can determine the amount of the sensing signal using at least one of the following methods A11 and A12.

[0035] A11. The first network device receives first instruction information transmitted from the second network device, which instructs the amount of the sensing signal to be measured by the first network device.

[0036] In other words, in such cases, the measured quantity of the sensing signal is what the AMF or sensing entity transmitted to the base station.

[0037] A12. The amount of the sensing signal to be measured is determined by the first sensing demand.

[0038] In other words, in such cases, the measured amount of the sensing signal is determined by the first network device itself based on the first sensing demand. Selectively, the first sensing demand may be transmitted to the terminal by the second network device or generated by the second network device.

[0039] Furthermore, in order to accurately transmit the sensing signal, the first network device needs to determine the setting information for the sensing signal before transmitting it.

[0040] Specifically, the step in which the first network device determines the setting information for the sensing signal is: Step B11: The first network device receives first configuration information of a sensing signal transmitted from the second network device. Step B12, in which the first network device determines second setting information for the sensing signal based on first information, includes at least one of the following: The aforementioned first information includes at least one of the following B121 and B122.

[0041] B121, 1st sensing demand.

[0042] It should be explained that the first sensing demand was transmitted from the second network device to the first network device.

[0043] B122, the first recommended configuration information determined by the first sensing demand of the second network device.

[0044] It should be explained here that the sensing signal configuration information may simply be what the AMF notifies the base station of, in which case the first configuration information includes all the settings for the sensing signal. The sensing signal configuration information may also be what the base station decides on its own, in which case the second configuration information includes all the settings for the sensing signal. The sensing signal configuration information may also be what the base station and the AMF entity (or sensing function entity) decide together, meaning that each device only decides on some of the parameters or some of the configuration information in the sensing signal configuration information.

[0045] For example, if the setting information for a sensing signal includes three setting parameters, A, B, and C, and the setting information for the sensing signal is simply notified to the base station by an AMF entity or a sensing function entity, then the first setting information includes the three setting parameters A, B, and C of the sensing signal. If the setting information for the sensing signal is simply determined by the base station itself, then the second setting information includes the three setting parameters A, B, and C of the sensing signal. If the setting information for the sensing signal is jointly determined by the base station and the AMF, then the first setting information includes some of the three setting parameters A, B, and C of the sensing signal (for example, the first setting information includes A), and the second setting information includes the other some of the three setting parameters A, B, and C of the sensing signal (for example, the second setting information includes B and C).

[0046] Further explanation is needed regarding the method by which the second network device determines the first setting information of the sensing signal. A method can be adopted in which the first setting information of the sensing signal is determined by the third piece of information. The aforementioned third information is, B21, first sensed demand; B22, sensing capability information transmitted by the first network device, and B23 includes at least one of the second recommended pieces of configuration information that the first network device determined based on the first sensed demand and transmitted to the second network device.

[0047] Furthermore, it should be explained that the first sensing demand described in the embodiment of the present application is associated with at least one of the following C11, C12, and C13.

[0048] C11, detected target.

[0049] Selectively, the sensing object includes, but is not limited to, at least one of the following: an object, a device, a person, an animal, a building, a car, the environment, air quality, humidity, temperature, and a specific area (i.e., a certain region).

[0050] C12, sensing quantity;

[0051] Selectively, the sensing quantity includes, but is not limited to, at least one of the following: the position of the object being sensed, the distance to the object being sensed, the speed of movement of the object being sensed, the image formed by the object being sensed, the trajectory of the object being sensed, the property analysis of the object being sensed, and the material analysis of the object being sensed.

[0052] C13, sensing index;

[0053] Selectively, the sensing indicator includes, but is not limited to, at least one of sensing accuracy, sensing error, sensing range, sensing delay, detection probability, and false alarm probability.

[0054] Specifically, the sensing accuracy includes distance resolution, imaging resolution, motion velocity resolution, or angular resolution, and the sensing error includes distance error, imaging error, or motion velocity error.

[0055] One thing to explain is that the combination of the object being detected and the amount detected results in the detection result.

[0056] Selectively, the first sensing demand can be further associated with setting information for the sensing signal or the measured quantity of the sensing signal.

[0057] As shown in Table 2, the first sensing demand can be divided into several sensing types, and at least one of the setting information for the sensing signal and the measured quantity of the sensing signal is associated with each sensing type. The association may be defined by a protocol or notified by signaling between different devices. When a sensing demand occurs, for example, if another device (e.g., a terminal) needs to measure and provide feedback on a quantity related to environmental reconfiguration, that sensing demand is sensing index 1. Optionally, a terminal device obtains sensing index 1 by receiving signaling transmitted from another device, and determines the setting information for the sensing signal and / or the measured quantity of the sensing signal using sensing index 1 and Table 2.

[0058] [Table 2]

[0059] Optionally, in another embodiment of the present application, after the first network device obtains a measurement value corresponding to the quantity to be measured, one of the following D11 and D12 is further included.

[0060] D11 transmits the measured quantity and the corresponding measured value to the second network device.

[0061] Optionally, in such cases, the second network device may determine the sensing result based on the measured quantity and the measured value corresponding to the measured quantity, and transmit the sensing result to a terminal (corresponding to cases where the terminal has initiated the sensing service) or a third network device (corresponding to cases where a device other than the terminal has initiated the sensing service). Specifically, the third network device may be a base station other than the sensing signal measurement base station, another network element in the core network, such as an application server (corresponding in such cases where a third-party application has initiated the sensing service), a network management system, etc.

[0062] Optionally, in such cases, the second network device can transmit the measured quantity and the corresponding measured value to the terminal or third network device, and the terminal or third network device can perform the conversion of the sensing result itself.

[0063] D12 determines the sensing result based on the measured quantity and the measured value corresponding to the measured quantity, and transmits the sensing result to the second network device.

[0064] Selectively, the measured quantity and the measured value corresponding to the measured quantity become the sensing result.

[0065] It should be explained that in such cases, after receiving the sensing result, the second network device can transmit the sensing result to the terminal or the third network device.

[0066] The following explanation uses the angle at the start of the sensing service as an example to illustrate the actions that the base station should perform after obtaining the measured values.

[0067] When a third-party application initiates a sensing service, the base station can optionally obtain a measurement value and then transmit the measured quantity and the corresponding measurement value to the sensing function entity. The sensing function entity determines the sensing result based on the measurement value and transmits it to the application server, which then transmits the sensing result to the third-party application. Alternatively, the base station can optionally obtain a measurement value and then determine the sensing result based on the measured quantity and the corresponding measurement value, and transmit the sensing result to the sensing function entity. The sensing function entity then transmits the sensing result to the application server, which then transmits the sensing result to the third-party application.

[0068] When the AMF initiates a sensing service, the base station can optionally obtain a measurement value and then transmit the measured quantity and the corresponding measurement value to the AMF, and the AMF can determine the sensing result based on the measurement value. Optionally, the base station can obtain a measurement value, then determine the sensing result based on the measured quantity and the corresponding measurement value, and transmit the sensing result to the AMF.

[0069] When a terminal initiates a sensing service, the base station can optionally obtain a measurement value and then transmit the measured quantity and the corresponding measurement value to the AMF. The AMF determines the sensing result based on the measurement value and transmits the sensing result to the terminal via Non-Access Stratum (NAS) signaling. Alternatively, the base station can optionally obtain a measurement value and then determine the sensing result based on the measured quantity and the corresponding measurement value and transmit the sensing result to the AMF. The AMF transmits the sensing result to the terminal via NAS signaling.

[0070] Furthermore, it should be explained that the sensing results described in the embodiments of this application include at least one of the following E11, E12, and E13.

[0071] E11, characteristic information of the target object.

[0072] For example, the characteristic information may include the presence, distance, position, velocity, acceleration, material, shape, type, radar scattering cross-section (RCS), polarization scattering characteristics, etc., of the target object.

[0073] E12, related information for the target event.

[0074] For example, the relevant information for the target event may include fall detection, intrusion detection, quantitative statistics, indoor positioning, gesture recognition, lip-reading recognition, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, etc.

[0075] E13, Information related to the target environment.

[0076] For example, relevant information about the target environment may include humidity, brightness, temperature and humidity, atmospheric pressure, air quality, weather conditions, topography, building / vegetation distribution, population statistics, crowd density, vehicle density, etc.

[0077] The sensing results of the embodiments of this application can be selected to further, E101, position of the target object, E102, distance to target, E103, target speed, E104, Target detection result, E105, Tracking results for the target object, E106. Recognition result of the target object. E107, imaging results of the target object, E108, target environment humidity, E109, target ambient temperature, and E110 may include at least one of the target environment air quality parameters.

[0078] The sensing function entity described in the embodiment of the present application satisfies at least one of the following F101 to F110.

[0079] F101 manages the overall consistency and scheduling of resources required for sensing.

[0080] F102 calculates the sensing result.

[0081] F103 estimates the detection accuracy.

[0082] F104, verify the detection results.

[0083] The F105 supports instant detection requests.

[0084] F106 supports delayed-sensing requests.

[0085] F107 supports periodic sensing requests or event-triggered sensing requests.

[0086] F108 supports the cancellation of periodic sensing operations or triggered sensing operations.

[0087] F109 corresponds to at least one AMF entity. In other words, multiple sensing function entities may be associated with a single AMF entity, or a single sensing function entity may be connected to multiple AMF entities in a corresponding manner.

[0088] F110 determines the sensing method based on the second piece of information. Here, the second information includes at least one of the following: the type of sensing client, the quality of service (QoS) of the sensing device, the sensing capability of the terminal, and the sensing capability of the first network device. The aforementioned sensing method relates to an entity that transmits and receives sensing signals, and specifically, the relationship between the entity corresponding to the sensing method and the transmitted and received signals includes at least one of the following F1101 to F1106.

[0089] F1101: The first network node transmits a sensing signal, and the second network node receives the sensing signal. This scenario involves base station 1 transmitting a sensing signal and base station 2 receiving the sensing signal.

[0090] F1102, the first network node, transmits and receives a sensing signal. This scenario involves base station 1 transmitting a sensing signal and base station 1 receiving a sensing signal.

[0091] F1103, the first network node transmits a sensing signal, and terminal equipment associated with the first network node receives the sensing signal. This scenario involves base station 1 transmitting a sensing signal and terminal receiving the sensing signal.

[0092] F1104: The first terminal device transmits a sensing signal, and the second terminal device receives the sensing signal. This scenario involves terminal A transmitting a sensing signal and terminal B receiving the sensing signal.

[0093] F1105, the first terminal device, transmits and receives a sensing signal. This scenario involves terminal A transmitting a sensing signal and terminal A receiving a sensing signal.

[0094] F1106: The first terminal device transmits a sensing signal, and the first network node receives the sensing signal. This scenario involves terminal A transmitting a sensing signal and base station 1 receiving the sensing signal.

[0095] Furthermore, it should be explained that the sensing function entity can 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 processes of the sensing service are completed in the Radio Access Network (RAN) (when the base station triggers the sensing service or when user equipment (UE) triggers the sensing service). The sensing function entity may be a standalone functional entity / physical entity, or it may be located on a general-purpose server of the core network and function as one of the core network functions, or it may be located on the base station side and function as one of the base station functions. The sensing function entity may directly exchange sensing requests and sensing results with an application server (e.g., a telecommunications carrier's application server), or the sensing function entity may exchange sensing requests and sensing results with an AMF, which can directly or indirectly (via a Gateway Mobile Location Center (GMLC) and a Network Exposure Function (NEF)) exchange sensing requests and sensing results with an application server (e.g., a third-party application server).

[0096] It should be explained that the setting information for the sensing signal in the embodiment of this application includes at least one of the following parameters H101 to H112.

[0097] H101, waveform of the sensing signal.

[0098] Examples include orthogonal frequency division multiplexing (OFDM), single-carrier frequency division multiple access (SC-FDMA), orthogonal time frequency space (OTFS), frequency modulated continuous wave (FMCW), and pulse signals.

[0099] H102, the subcarrier interval of the sensing signal.

[0100] For example, the subcarrier spacing in an OFDM system is 30 kHz.

[0101] H103, the guard interval for the aforementioned sensing signal.

[0102] It should be explained that the guard interval is the time interval from the end of signal transmission to the time when the latest echo signal of that signal is received. This parameter is directly proportional to the maximum sensing distance and can be calculated, for example, by 2dmax / c, where dmax is the maximum sensing distance (belonging to the sensing demand). For example, in a self-transmitting sensing signal, dmax represents the maximum distance from the sensing signal transmission / reception point to the signal reflection point. In some cases, the OFDM signal cyclic prefix (CP) can function as the minimum guard interval.

[0103] H104, the bandwidth of the sensing signal.

[0104] It should be explained that this parameter is inversely proportional to the distance resolution and can be obtained by c / (2×delta_d), where delta_d is the distance resolution (belonging to the sensing demand) and c is the speed of light.

[0105] H105, the burst duration of the sensing signal.

[0106] It should be explained that the burst duration is inversely proportional to the velocity factor resolution (belonging to the sensing demand), is the temporal span of the sensing signal, and is mainly used to calculate the Doppler frequency offset. This parameter can be calculated by c / (2 × delta_v × fc), where delta_v is the velocity resolution and fc is the carrier frequency of the sensing signal.

[0107] H106, the time domain interval of the sensing signal.

[0108] It should be explained that the time domain interval can be calculated by c / (2×fc×v_range), where v_range is the maximum speed rate minus the minimum speed (belonging to the sensing demand), and this parameter is the time interval between two adjacent sensing signals.

[0109] H107, the transmission signal power of the sensing signal.

[0110] For example, it takes one value every 2 dBm from -20 dBm to 23 dBm.

[0111] H108, Signal format of the sensing signal.

[0112] For example, the signal format may be information such as a Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), Positioning Reference Signal (PRS), or other predefined signals, and related sequence formats.

[0113] H109, ​​the signal direction of the sensing signal.

[0114] For example, the signal direction may be the direction of the sensing signal or beam information.

[0115] H110, the time resource of the sensing signal.

[0116] For example, the time resource may be the slot index or the symbol index of the slot where the sensing signal is located, and the time resources can be divided into two types: the first is a one-time time resource, for example, one symbol transmits one omnidirectional first signal; and the second is a time resource that is not one-time, for example, multiple sets of periodic time resources or discontinuous time resources (which may include a start time and an end time), where each set of periodic time resources transmits a sensing signal in the same direction, and the beam direction differs for different sets of periodic time resources.

[0117] H111, the frequency resource of the sensing signal.

[0118] Selectively, the frequency resource includes the center frequency point of the sensing signal, bandwidth, resource block (RB) or subcarrier, reference point (Point A), starting bandwidth position, etc.

[0119] H112, Quasi-co-location (QCL) relationship of the aforementioned sensing signal.

[0120] For example, a sensing signal may contain multiple resources, each resource being a QCL for a single synchronization signal / physical broadcast channel signal block (or synchronization signal block, SSB), and the QCL may be of type A, type B, type C, or type D.

[0121] It should be explained that the measured quantity in the embodiment of this application includes at least one of the following K11 and K12.

[0122] K11, the first type of measurement.

[0123] Specifically, the measured quantity of type 1 described above is K111, channel matrix H, K112, Received Signal Strength Indicator (RSSI), K113, Reference Signal Received Power (RSRP), K114, Channel Status Information (CSI), K115, power of each path in a multipath channel, K116, delay of each path in a multipath channel, K117, angle information for each path in a multipath channel. K118, Doppler extension, K119, 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, and K122 includes at least one of the characteristic differences between the I-channel signal and the Q-channel signal.

[0124] The characteristic difference to be explained may be a phase difference or other difference between the I-channel signal and the Q-channel signal.

[0125] It should be explained here that the I-channel signal and the Q-channel signal are in-phase and quadrature signals, respectively. I is in-phase, and Q is quadrature, and the phases of the I-channel signal and the Q-channel signal are 90 degrees apart.

[0126] K12, the second type of measurement.

[0127] Specifically, the second type of measurement includes at least one of the following K121, K122, and K123.

[0128] K121, characteristic information of the target object.

[0129] It should be explained that the characteristic information of the target object is information that can reflect the attributes or location of the target object, and may be at least one of the following: the existence of the target object, the distance to the target object, the position of the target object, the velocity 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, polarization scattering characteristics, etc.

[0130] K122, related information for the target event.

[0131] It should be explained that the information related to 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 the following: fall detection, intrusion detection, quantitative statistics, indoor positioning, gesture recognition, lip-reading recognition, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, etc.

[0132] K123, related information on the target environment.

[0133] The information to be explained may include at least one of the following: humidity, brightness, temperature and humidity, atmospheric pressure, air quality, weather conditions, topography, building / vegetation distribution, population statistics, crowd density, vehicle density, etc.

[0134] Selectively, the measured quantity may further include at least one of the following K21 and K22.

[0135] K21, location, material, shape, and / or type of the reflection point.

[0136] K22, radar spectrum information.

[0137] Selectively, the measured quantity may be a measured quantity for each antenna or a measured quantity for each sensing resource.

[0138] For example, the above measurement quantity is the measurement quantity of each antenna (port) on the transmitting or receiving side, or the measurement quantity is the measurement quantity of each sensing resource, for example, the measurement quantity of each resource block (RB), subcarrier, or RB group.

[0139] It should be explained that when the core network transmits sensing-related information to a base station, the core network or sensing network functional entity / sensing network element determines which base station is relevant based on the target area, and also determines the direction in which that base station transmits the sensing signal.

[0140] Below, we will explain specific use cases for practical application, using examples.

[0141] Specific Use Case 1: Base station 1 transmits and receives sensing signals itself, and a third-party application initiates the sensing service.

[0142] The network equipment involved in this case is shown in Figure 5, and the implementation process in this case is mainly as follows.

[0143] In step S101, the application server receives a sensing request from a third-party application.

[0144] For example, the sensing requirement is to sense a three-dimensional map of the target area (with a map accuracy / resolution of 5m), and the target area may be a specified area, such as the area around a building, or the area surrounding a target UE, and the sensing requirement may include information about the target area, such as the area's latitude and longitude (range).

[0145] In step S102, the application server (including an in-network server or an out-of-network server such as an IP Multimedia Subsystem (IMS)) sends a sensing request to the core network (e.g., AMF) or the sensing network function entity / sensing network element of the core network (if any), Alternatively, the application server sends the sensing request to the AMF, and the AMF forwards the request to the sensing network function entity / sensing network element.

[0146] What needs to be explained here is that the sensing network function entity / sensing network element of the core network exchanges target information (target information includes sensing processing requests, interactive sensing capabilities, interactive sensing support data, interactive sensing measurements, or sensing results) with the target UE or the serving base station of the target UE, and obtains target sensing results or sensing measurements (uplink measurements or downlink measurements). Furthermore, based on the target area, it can interact with other network elements / functions within the core network to obtain information about base stations that may require information exchange.

[0147] Furthermore, it should be explained that when the AMF forwards the demand to a sensing network function entity / sensing network element, and multiple sensing network function entities / sensing network elements can correspond to a single AMF, there was a problem in selecting the sensing network function entity / sensing network element (the AMF makes the selection).

[0148] Factors that AMF considers when selecting a sensing network function entity / sensing network element include at least one of the following: QoS of the request (e.g., sensing accuracy, response time, sensing QoS level), access type (3GPP® access / non-3GPP® access), access network (AN) type of the target UE (i.e., 5G NR or eLTE) and service AN node (i.e., gNodeB or NG-eNodeB), RAN configuration information, sensing network function entity / sensing network element capability, sensing network function entity / sensing network element traffic load, sensing network function entity / sensing network element location, indication for single-event or multiple-event notification, event notification duration, network slice information, etc.

[0149] In step S103, the core network (or sensing network function entity / sensing network element) transmits setting information for sensing demand or sensing signal to the base station 1.

[0150] Furthermore, it should be explained that the setting information for the sensing signal may be associated with the sensing demand, and simply notifying the sensing demand is sufficient for the receiving side to determine the setting information for the sensing signal based on the sensing demand and its relationship.

[0151] To select the steps to determine the setting information of the sensing signal based on sensing demand (for example, determining the bandwidth of the sensing signal based on the resolution sensing demand), the following methods are primarily included: In Y11, base station 1 informs the core network of its sensing capabilities (capabilities related to transmitting sensing signals, e.g., maximum bandwidth for transmitting sensing signals, maximum transmission power of sensing signals, etc.), and / or base station 2 informs the core network (AMF or sensing network function entity / sensing network element) of its sensing capabilities (capabilities related to receiving sensing signals, e.g., maximum bandwidth for receiving sensing signals, supported sensing signal measurement values, etc.), and subsequently the core network determines the setting information for sensing signals based on sensing demand. In Y12, the base station determines the setting information for the sensing signal based on the sensing demand. In Y13, the core network determines the configuration information for some of the sensing signals, and the base station determines the configuration information for other parts of the sensing signals. In Y14, the core network recommends detection signal configuration information to base stations based on detection demand, and the base stations ultimately determine the detection signal configuration information. In Y15, the base station recommends detection signal configuration information to the core network based on detection demand, and the core network ultimately determines the detection signal configuration information.

[0152] What needs to be explained here is that the method for determining base station 1 involves the core network or sensing network function entity / sensing network element determining that the relevant base station is base station 1 based on the target area, and also determining the direction in which base station 1 transmits the sensing signal.

[0153] In step S104, the core network (or sensing network function entity / sensing network element) transmits a measurement related to the sensing signal (e.g., angle of arrival (AOA), angle of departure (AOD), delay, RSRP, radar spectrum information, etc.) to base station 1 (receiving base station), or It does not require a separate signaling instruction; the base station 1 determines the measurement quantity based on the perceived demand (mapping table from perceived demand to measurement quantity).

[0154] In step S105, base station 1 transmits a sensing signal.

[0155] It should be explained that base station 1 transmits the sensing signal using the beam sweeping method.

[0156] In step S106, base station 1 receives a sensing signal.

[0157] After receiving the sensing signal, the UE obtains a measurement value for the corresponding quantity, and can select one of the following processing methods for that measurement value.

[0158] Processing method 1: The conversion from measured quantity to sensing result is completed on the core network or application server.

[0159] In step S107, base station 1 transmits the measured amount to the core network (or sensing network function entity / sensing network element).

[0160] In step S108, the core network (or sensing network function entity / sensing network element) transmits the measured quantity to the application server, and the application server determines the sensing result based on the measured quantity, or The core network (or sensing network function entity / sensing network element) determines the sensing result based on the measured quantity and sends the sensing result to the application server.

[0161] In step S109, the application server sends the detection result to the third-party application.

[0162] Processing method 2: The conversion from measured quantity to sensing result is completed at the base station.

[0163] In step S107, base station 1 determines the sensing result based on the measured amount and transmits the measurement result to the core network (or sensing network function entity / sensing network element).

[0164] In step S108, the core network (or sensing network function entity / sensing network element) sends the sensing result to the application server.

[0165] In step S109, the application server sends the detection result to the third-party application.

[0166] Furthermore, to assist in the completion of the conversion process, it is necessary to transmit relevant information from base station 1, such as antenna position, synchronization information (Single Frequency Network (SFN) start time), and information related to artificial intelligence (AI), to the node that completes the above conversion.

[0167] Furthermore, it should be explained that the billing function is completed within the core network or application server.

[0168] Furthermore, it should be explained that the sensing signals during the above process may be transmitted by multiple base stations, and the sensing signals may be received by multiple base stations, while base station 1 during the above process may be TRP A.

[0169] Specific Use Case 2: Base station 1 transmits and receives sensing signals on its own, and the core network (or network management system, or base station) initiates the sensing service.

[0170] The implementation process in this case is mainly as follows:

[0171] In step S201, the core network AMF transmits sensing demand or sensing signal configuration information to the sensing network function entity / sensing network element (e.g., network management demand). For example, the sensing requirement is to sense a three-dimensional map of the target area (with a map accuracy / resolution of 5m), and the target area may be a specified area, such as the area around a building, or the area surrounding a target UE, and the sensing requirement may include information about the target area, such as the area's latitude and longitude (range). Alternatively, the AMF receives configuration information for sensing demand or sensing signals transmitted from the network management system and forwards it to the sensing network function entity / sensing network element. Alternatively, the AMF receives the sensing demand or sensing signal configuration information transmitted from the base station and forwards it to the sensing network function entity / sensing network element (it should be noted that the sensing demand or sensing signal configuration information from base station 1 can be transmitted directly to base station 2 without being transmitted to the core network).

[0172] In step S202, a sensing network function entity / sensing network element (whose characteristics are the same as those described in Example 1) transmits sensing demand or sensing signal configuration information to base station 1 (or, the AMF transmits sensing demand or sensing signal configuration information to base station 1).

[0173] Furthermore, it should be explained that the setting information for the sensing signal may be associated with the sensing demand, and simply notifying the sensing demand is sufficient for the receiving side to determine the setting information for the sensing signal based on the sensing demand and its relationship.

[0174] For the main implementations in which the setting information of the sensing signal is determined by the sensing demand (for example, determining the bandwidth of the sensing signal based on the resolution sensing demand), please refer to the description above, and a detailed explanation will be omitted here.

[0175] In step S203, the core network (or sensing network function entity / sensing network element) transmits a measurement related to the sensing signal (e.g., AOA, AOD, delay, RSRP, radar spectrum information, etc.) to base station 1 (receiving base station), or It does not require a separate signaling instruction; the base station 1 determines the measurement quantity based on the perceived demand (mapping table from perceived demand to measurement quantity).

[0176] In step S204, base station 1 transmits a sensing signal.

[0177] One thing to explain is that base station 1 transmits the sensing signal using the beam sweeping method.

[0178] In step S205, base station 1 receives a sensing signal.

[0179] After receiving the sensing signal, the UE obtains a measurement value for the corresponding quantity, and can select one of the following processing methods for that measurement value.

[0180] Processing method 1: The conversion from measured quantity to sensing result is completed in the core network.

[0181] In step S206, base station 1 transmits the measured amount to the core network (AMF or sensing network function entity / sensing network element).

[0182] In step S207, the core network (AMF or sensing network function entity / sensing network element) converts the measured quantity into a sensing result. If the core network's sensing demand originates from the network management system, the core network transmits the sensing result to the network management system, or the core network transmits the measured quantity to the network management system, and the network management system converts the measured quantity into a sensing result. If the core network's sensing request originates from a base station, the core network transmits the sensing result to the base station.

[0183] Processing method 2: The conversion from measured quantity to sensing result is completed at the base station.

[0184] In step S206, base station 1 determines the sensing result based on the measured amount and transmits the measurement result to the core network (AMF or sensing network function entity / sensing network element). If the core network's sensing request originates from the network management system, the core network sends the sensing result to the network management system. If the core network's sensing request originates from a base station, the core network transmits the sensing result to the base station.

[0185] One important point to note here is that, when a sensing network function entity / sensing network element is located at a base station, one possible option is to perform sensing services without going through the core network at all.

[0186] Furthermore, it should be explained that the sensing signals during the above process may be transmitted by multiple base stations, and the sensing signals may be received by multiple base stations, while base station 1 during the above process may be TRP A.

[0187] Specific Use Case 3: Base Station 1 transmits and receives sensing signals on its own, and the UE initiates the sensing service.

[0188] The implementation process in this case is mainly as follows:

[0189] In step S301, the UE transmits sensing demand or sensing signal setting information to the AMF via NAS signaling. For example, the sensing demand is to sense a three-dimensional map of a target area (with a map accuracy / resolution of 5m), and the target area may be a specified area, such as the area around a building, or the area around the target UE, and the sensing demand may include information about the target area, such as the area's latitude and longitude (range).

[0190] In step S302, the AMF transmits setting information for the sensed demand or sensed signal to the sensed network function entity / sensed network element.

[0191] In step S303, a sensing network function entity / sensing network element (whose characteristics are the same as those described in specific use case 1) transmits sensing demand or sensing signal configuration information to base station 1 (or the AMF transmits sensing demand or sensing signal configuration information to base station 1).

[0192] Furthermore, it should be explained that the setting information for the sensing signal may be associated with the sensing demand, and simply notifying the sensing demand is sufficient for the receiving side to determine the setting information for the sensing signal based on the sensing demand and its relationship.

[0193] The step of selecting how to determine the setting information of the sensing signal based on sensing demand (for example, determining the bandwidth of the sensing signal based on the resolution sensing demand) mainly includes at least one of the following methods. In Y21, base station 1 informs the core network (AMF or sensing network function entity / sensing network element) of its sensing capabilities (capabilities related to transmitting sensing signals, e.g., maximum bandwidth for transmitting sensing signals, maximum transmission power of sensing signals, etc.), and / or base station 1 informs the core network of its sensing capabilities (capabilities related to receiving sensing signals, e.g., maximum bandwidth for receiving sensing signals, supported sensing signal measurement values, etc.), and subsequently the core network determines the setting information for sensing signals based on sensing demand. In Y22, the base station determines the setting information for the sensing signal based on the sensing demand. In Y23, the core network determines the configuration information for some of the sensing signals, while the base station determines the configuration information for other parts of the sensing signals. In Y24, the core network recommends detection signal configuration information to base stations based on detection demand, and the base stations ultimately determine the detection signal configuration information. In Y25, the base station recommends detection signal configuration information to the core network based on detection demand, and the core network ultimately determines the detection signal configuration information. In Y26, the UE recommends detection signal configuration information to the base station based on detection demand, and the base station ultimately determines the detection signal configuration information. In Y27, the UE recommends sensing signal configuration information to the core network based on sensing demand, and the core network ultimately determines the sensing signal configuration information. In Y28, the UE determines the setting information for the sensing signal based on the sensing demand.

[0194] In step S304, the core network (or sensing network function entity / sensing network element) transmits a measurement related to the sensing signal (e.g., AOA, AOD, delay, RSRP, radar spectrum information, etc.) to base station 1 (receiving base station), or It does not require a separate signaling instruction; the base station 1 determines the measurement quantity based on the perceived demand (mapping table from perceived demand to measurement quantity).

[0195] In step S305, base station 1 transmits a sensing signal.

[0196] One thing to explain is that base station 1 transmits the sensing signal using the beam sweeping method.

[0197] In step S306, base station 1 receives a sensing signal.

[0198] After receiving the sensing signal, the UE obtains a measurement value for the corresponding quantity, and can select one of the following processing methods for that measurement value.

[0199] Processing method 1: The conversion from measured quantity to sensing result is completed in the core network.

[0200] In step S307, base station 1 transmits the measured amount to the core network (AMF or sensing network function entity / sensing network element).

[0201] In step S308, the core network (AMF or sensing network function entity / sensing network element) determines the sensing result based on the measured quantity.

[0202] In step S309, the core network (AMF or sensing network function entity / sensing network element) sends the sensing result to the UE (via NAS signaling).

[0203] Processing method 2: The conversion from measured quantity to sensing result is completed at base station 1.

[0204] In step S307, base station 1 determines the sensing result based on the measured quantity and transmits the measurement result to the core network (AMF or sensing network function entity / sensing network element).

[0205] In step S308, the core network (AMF or sensing network function entity / sensing network element) sends the sensing result to the UE (via NAS signaling).

[0206] Processing method 3: The conversion from the measured quantity to the sensing result is completed in the UE.

[0207] In step S307, base station 1 transmits the measured amount to the core network (or sensing network function entity / sensing network element).

[0208] Step S308, the core network (AMF or sensing network function entity / sensing network element) transmits the measurement to the UE (by NAS signaling).

[0209] In step S309, the UE determines the sensing result based on the measured quantity.

[0210] Furthermore, it should be explained that the sensing signals during the above process may be transmitted by multiple base stations, and the sensing signals may be received by multiple base stations, while base station 1 during the above process may be TRP A.

[0211] It should be explained that the embodiments of the present invention provide a process related to wireless sensing based on a base station transmitting sensing signals, specifically including a sensing process in which the base station itself sends and receives sensing signals, signaling exchange between different sensing nodes, etc., thereby adding new functions to the sensing network functional entity / sensing network element, thereby completing the network communication process and ensuring smooth sensing.

[0212] It should be explained that the sensing method provided in the embodiment of this application may be implemented by a sensing device or a control module for executing the sensing method in said sensing device.
