Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority of Chinese Patent Application No. 202110839605.X filed in China on July 23, 2021, and all of its contents are incorporated herein by reference. This application belongs to the field of communications, and in particular, relates to a sensing method, device, and network device.

Background Art

[0002] For example, future mobile communication systems such as B5G systems or 6G systems will not only have communication capabilities but also sensing capabilities. The sensing ability means that one or more devices equipped with sensing capabilities can sense information such as the orientation, distance, and speed 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. In the future, with the deployment of small base stations with high - frequency bands such as millimeter - waves and terahertz and wide - bandwidth capabilities in 6G networks, the sensing resolution will be significantly higher compared to the case of centimeter - waves, 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, the base station can provide a more accurate beamforming alignment device by tracking the movement trajectory of the device. The other is sensing that has no direct relation to communication, such as the base station monitoring the weather conditions by wireless signals and the mobile phone recognizing the user's gestures by millimeter - wave wireless sensing.

[0004] Sensing methods can be classified into the following several methods. (1) Active sensing: As shown in FIG. 1, the 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 FIG. 2, the transmitter and receiver are at different positions, and the receiver senses using the radio signal transmitted by the transmitter. For example, base station A senses the environmental information between base station A and base station B by receiving the radio signal from base station B. (3) Interactive sensing: Between the sensor and the target object, the electromagnetic wave transmission subject, time, frequency, format, etc. are defined through information exchange to complete the sensing process.

[0005] In the related art, there is no process related to wireless sensing, and the communication process is incomplete.

[0022] Hereinafter, while referring to the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly described. Naturally, the described embodiments are part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the protection scope of the present application.

It should be understood that such terms may be replaced with each other when appropriate so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein.

Furthermore, for example, it can be used in 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), and Single-carrier Frequency-Division Multiple Access (SC-FDMA), as well as in other systems.

However, for the purpose of illustration in the following description, the New Radio (NR) system is described, and the NR term is used in most of the following descriptions. These terms are applicable to systems other than the NR system, for example, they are also applicable to the 6th Generation (6G) communication system. th Generation, 6G) communication system.

[0025] Next, first, the related technologies related to the present application will be described as follows.

[0026] The functions and application uses of wireless sensing are shown in Table 1.

[0027]

Table 1

[0028] Any sensing function in Table 1 or other sensing requirements can be realized by transmitting a sensing signal and receiving / detecting the sensing signal. Here, the device for transmitting the sensing signal and receiving / detecting the sensing signal may be the same device or different devices.

[0029] From the following four aspects, the integrated design of communication and sensing is feasible. Both the communication system and the sensing system are based on electromagnetic wave theory, and the acquisition and transmission of information are completed by transmitting and receiving electromagnetic waves. Both the communication system and the sensing system are equipped with components such as antennas, transmitters, receivers, and signal processors, and there is a lot of overlap in hardware resources. With the development of technology, there is a tendency for their operating frequency bands to overlap more. There are similarities in key technologies such as signal modulation, reception detection, and waveform design.

[0030] 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 transmitting information, it has sensing capabilities or provides sensing services.

[0031] The advantages of the integrated communication and sensing include Cost savings, Miniaturization of devices, Reduction of device power consumption, Improvement of spectral efficiency, Including reduction of mutual interference between communication and sensing and improvement of system performance.

[0032] Currently, the scope of the integrated communication and sensing is not clearly defined. In a broad sense, the integrated communication and sensing means Providing communication services and sensing services by the same network, Providing communication services and sensing services by the same terminal, Providing communication services and sensing services in the same frequency spectrum. Include completing the integrated communication and sensing service integrated in one wireless transmission, that is, the collaborative design of communication signals and sensing signals.

[0033] A schematic diagram of the waveform integration classification of sensing and communication is shown in FIG. 3.

[0034] Hereinafter, with reference to the drawings, the sensing method, apparatus, and network device provided in the embodiments of the present application will be described in detail by several embodiments and their use cases.

[0035] As shown in FIG. 4, the embodiments of the present application provide a sensing method including the following steps 401 and 402.

[0036] In step 401, the first network device determines the measurement quantity of the sensing signal.

[0037] It should be noted that the sensing signal described in the embodiments of the present application is the sensing signal that the terminal should measure, and for example, it may be one or several sensing signals.

[0038] In step 402, the first network device detects the sensing signal and obtains a measurement value corresponding to the measurement quantity.

[0039] Here, the sensing signal is transmitted from the second network device, and the first network device and the second network device are different base stations.

[0040] It should be noted that the embodiments of the present application mainly describe the case where one base station transmits a sensing signal and another base station receives and detects the sensing signal to obtain a measurement value. That is, the first network device described in the embodiments of the present application is one base station (for example, base station A) or one transmission and reception point (TRP) on the access network side, and the second network device is another base station (for example, base station B) or another TRP on the access network side. The third network device described in the embodiments of the present application may be an access and mobility management function (AMF) entity on the core network side. The third network device may also be a sensing function entity, for example, a sensing network function entity or a sensing network element. The sensing function entity may be on the core network side or on the access network side. The third network device may also be another function entity on the core network side.

[0041] It should be noted that the first network device can determine the measurement amount of the sensing signal by using at least one of the following methods A11 and A12.

[0042] A11: Receive first indication information for indicating the measurement amount of the sensing signal to be measured by the first network device, which is transmitted from the second network device or the third network device.

[0043] That is, in such a case, the measurement amount of the sensing signal may be the one transmitted by the base station that transmits the sensing signal to the base station, or the one transmitted by the AMF or the sensing function entity to the base station.

[0044] A12: Determine the measurement amount of the sensing signal to be measured by the first network device according to the first sensing requirement.

[0045] That is, in such a case, the measured amount of the sensing signal is determined by the first network device itself according to the first sensing requirement, and the first sensing requirement is sent by the second network device or the third network device to the first network device.

[0046] Furthermore, in order to accurately receive the sensing signal, the first network device needs to determine the setting information of the sensing signal before receiving the sensing signal.

[0047] Specifically, the step in which the first network device determines the setting information of the sensing signal includes step B11 of the first network device receiving the first setting information of the sensing signal sent from the second network device, step B12 of the first network device receiving the second setting information of the sensing signal sent from the third network device, and at least one of step B13 in which the first network device determines the third setting information of the sensing signal according to the first sensing requirement.

[0048] It should be noted that the first sensing requirement is sent by the second network device or the third network device to the first network device.

[0049] Here, what should be explained is that the setting information of the sensing signal may only be what the second network device notifies the first network device. In such a case, what is included in the first setting information is all the settings of the sensing signal. The setting information of the sensing signal may only be what the AMF entity or the sensing function entity notifies the first network device. In such a case, what is included in the second setting information is all the settings of the sensing signal. The setting information of the sensing signal may further only be what the first network device determines by itself. In such a case, what is included in the third setting information is all the settings of the sensing signal. The setting information of the sensing signal may further be determined by at least two of the first network device, the second network device, and the AMF entity (or the sensing function entity). That is, each device only determines some of the parameters or some of the setting information in the setting information of the sensing signal.

[0050] For example, when the setting information of the sensing signal includes three setting parameters such as A, B, and C, and the setting information of the sensing signal is only what the base station B notifies the base station A, what is included in the first setting information is the three setting parameters of the sensing signal, namely A, B, and C. When the setting information of the sensing signal is only what the AMF entity or the sensing function entity notifies the base station A, what is included in the second setting information is the three setting parameters of the sensing signal, namely A, B, and C. When the setting information of the sensing signal is only what the base station A determines by itself, what is included in the third setting information is the three setting parameters of the sensing signal, namely A, B, and C. When the setting information of the sensing signal is what the base station B and the AMF notify the base station A, what is included in the first setting information is some of the three setting parameters of the sensing signal, namely A, B, and C (for example, the first setting information includes A), and what is included in the second setting information is the other part of the three setting parameters of the sensing signal, namely A, B, and C (for example, the first setting information includes B and C). By analogy, the same is true for other cases, and it will not be explained one by one here.

[0051] The following describes the process before base station A detects a sensing signal, taking base station A, base station B, and a sensing function entity as examples in such a case.

[0052] Scenario 1: Base station A receives a first sensing requirement sent from a sensing function entity, and base station A determines setting information of a sensing signal based on the first sensing requirement. Base station B determines the setting information of the sensing signal. Base station A receives first indication information sent from the sensing function entity for indicating the measurement amount of the sensing signal to be measured by base station A. Base station B transmits a sensing signal according to the setting information of the sensing signal, and base station A receives the sensing signal according to the setting information of the sensing signal.

[0053] Here, as for the method by which base station B determines the setting information of the sensing signal, it includes one of the following two methods: a method in which a second network device receives second setting information of a sensing signal sent from a third network device; and a method in which the second network device determines first setting information of the sensing signal according to second information. Here, the second information includes at least one of the following B111, B112, and B113.

[0054] B111, the first sensing requirement.

[0055] In such a case, the first sensing requirement is sent by the third network device to the second network device.

[0056] B112, first recommended information of setting information determined by the third network device according to the first sensing requirement.

[0057] B113, second recommended information of setting information sent by the first network device to the second network device.

[0058] ​Scene 2: The base station A receives the first sensing requirement sent from the base station B, and the base station A determines the setting information of the sensing signal according to the first sensing requirement. The base station B receives the setting information of the sensing signal sent from the sensing function entity. The base station A receives the first indication information sent from the base station B for indicating the measurement amount of the sensing signal to be measured by the base station A. The base station B transmits the sensing signal according to the setting information of the sensing signal, and the base station A receives the sensing signal according to the setting information of the sensing signal.

[0059] Specifically, as a method for the sensing function entity to determine the setting information of the sensing signal, it includes a method for determining the second setting information of the sensing signal according to the third information. Here, the third information includes at least one of the following B121 to B126.

[0060] B121, the first sensing requirement.

[0061] B122, the sensing capability information sent by the second network device.

[0062] For example, the sensing capability information may be the measurement amount related capability supported by the second network device. For example, what measurement amounts can the terminal support for acquisition? Further, for example, the sensing capability information may be the format information of the sensing signal that the second network device can transmit. For example, the maximum bandwidth of the sensing signal that the second network device can transmit is 100 MHz. The sensing capability information can be notified by the second network device to the third network device.

[0063] B123, the sensing capability information sent by the first network device.

[0064] For example, the sensing capability information may be a measurement-related capability supported by the first network device. For example, what kind of measurement can the first network device support? Further, for example, the sensing capability may be format information of a sensing signal that the first network device can detect. For example, the maximum bandwidth of the sensing signal that the first network device can detect is 100 MHz. The sensing capability can be notified by the first network device to the second network device.

[0065] B124. The third recommendation information of the first sensing information, which is determined by the second network device according to the first sensing requirement and transmitted to the third network device.

[0066] B125. The fourth recommendation information of the first sensing information, which is determined by the first network device according to the first sensing requirement and transmitted to the third network device.

[0067] B126. The fifth recommendation information of the first sensing information, which is transmitted by the first network device to the third network device.

[0068] Furthermore, it should be further explained that the first sensing requirement described in the embodiments of the present application is associated with at least one of the following C11, C12, and C13.

[0069] C11. Sensing target.

[0070] Optionally, the sensing target includes, but is not limited to, at least one of an object, a device, a human, an animal, a building, a vehicle, an environment, air quality, humidity, temperature, and a specific area (i.e., a certain area).

[0074] Optionally, 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.

[0075] Specifically, the sensing accuracy includes distance resolution, imaging resolution, moving speed resolution, or angular resolution, and the sensing error includes distance error, imaging error, or moving speed error.

[0076] It should be noted that the combination of the sensing object and the sensed quantity is the sensing result.

[0077] Optionally, the first sensing requirement can be further associated with the setting information of the sensing signal or the measured quantity of the sensing signal.

[0078] As shown in Table 2, the first sensing requirement can be divided into several sensing types, and at least one of the setting information of the sensing signal and the measured quantity of the sensing signal is associated with each sensing type. The association relationship may be defined by a protocol or notified by signaling between different devices. When a device has a sensing requirement, for example, when the sensing requirement is that another device (e.g., base station A) needs to measure and feedback the measured quantity related to the environment reconstruction, the sensing requirement is sensing index 1. Optionally, base station A obtains sensing index 1 by receiving the signaling transmitted from other devices, and determines the setting information of the sensing signal and / or the measured quantity of the sensing signal according to sensing index 1 and Table 2.

The third network device performs conversion of the sensing result and transmits the sensing result to a terminal (corresponding to the case where the terminal starts a sensing service) or a fourth network device (corresponding to the case where a device other than the terminal starts a sensing service). Specifically, the fourth network device may be a base station other than the sensing signal measurement base station, other network elements in the core network, such as an application server (corresponding to the case where a third-party application starts a sensing service), a network management system, etc.

[0083] 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 can also convert the measurement quantity and the measurement value corresponding to the measurement quantity into a sensing result and transmit the sensing result to the third network device.

[0113] F1102: The first network node transmits and receives the sensing signal. In such a case, it means that base station A transmits the sensing signal and base station A receives the sensing signal.

[0114] F1103: The first network node transmits the sensing signal, and the terminal device related to the first network node receives the sensing signal. Such a case means that the base station A transmits a sensing signal and the terminal receives the sensing signal.

[0115] F1104. The first terminal device transmits a sensing signal and the second terminal device receives the sensing signal. Such a case means that the terminal A transmits a sensing signal and the terminal B receives the sensing signal.

[0116] F1105. The first terminal device transmits and receives a sensing signal. Such a case means that the terminal A transmits a sensing signal and the terminal A receives the sensing signal.

[0117] F1106. The first terminal device transmits a sensing signal and the first network node receives the sensing signal. Such a case means that the terminal A transmits a sensing signal and the base station A receives the sensing signal.

[0118] Furthermore, it should be noted 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 the User Equipment (UE) triggers the sensing service). The sensing function entity may be a single functional entity / physical entity, or may be arranged in a general-purpose server of the core network as one of the core network functions, or may be arranged on the base station side as one of the base station functions. The sensing function entity directly exchanges sensing requests and sensing results with an application server (for example, an application server of a communication operator), or the sensing function entity exchanges sensing requests and sensing results with the AMF, and the AMF directly or indirectly (via the Gateway Mobile Location Center (GMLC) and the Network Exposure Function (NEF)) exchanges sensing requests and sensing results with an application server (for example, a third-party application server).

[0119] It should be noted that the setting information of the sensing signal in the embodiments of the present application includes at least one parameter among the following H101 to H112.

[0120] H101, the waveform of the sensing signal.

[0121] For example, Orthogonal Frequency Division Multiplexing (OFDM), Single-carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), pulse signals, etc.

[0122] H102, the subcarrier spacing of the sensing signal.

[0123] For example, the subcarrier spacing of an OFDM system is 30 KHz.

[0124] H103, the guard interval of the sensing signal.

[0125] It should be noted that the guard interval is the time interval from the end time of signal transmission to the time when the latest echo signal of the signal is received. This parameter is directly proportional to the maximum sensing distance and can be calculated by, for example, 2dmax / c, where dmax is the maximum sensing distance (belonging to the sensing requirement). For example, in the case of self-transmitting and receiving sensing signals, dmax represents the maximum distance from the sensing signal transmitting and receiving point to the signal reflection point. In some cases, the OFDM signal Cyclic Prefix (CP) can function as the minimum guard interval.

[0126] H104, the bandwidth of the sensing signal.

[0127] It should be noted that this parameter is inversely proportional to the range resolution and can be obtained by c / (2×delta_d), where delta_d is the range resolution (belonging to the sensing requirement) and c is the speed of light.

[0128] H105, the burst duration of the sensing signal.

[0129] It should be noted that the burst duration is inversely proportional to the velocity resolution (belonging to the sensing requirement), is the time 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.

[0130] H106, the time domain interval of the sensing signal.

[0131] It should be noted that the time domain interval can be calculated by c / (2×fc×v_range), where v_range is the result of subtracting the minimum velocity from the maximum velocity rate (belonging to the sensing requirement), and this parameter is the time interval between two adjacent sensing signals.

[0132] H107, the transmission signal power of the sensing signal.

[0133] For example, it takes a value every 2 dBm from -20 dBm to 23 dBm.

[0134] H108, the signal format of the sensing signal.

[0135] For example, the signal format may be information such as a sounding reference signal (SRS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), etc. or other predefined signals, and related sequence formats.

[0136] H109, the signal direction of the sensing signal.

[0137] For example, the signal direction may be the direction of the sensing signal or beam information.

[0138] H110, the time resource of the sensing signal.

[0139] For example, the time resource may be the slot index or symbol index of the slot where the sensing signal is located. Here, the time resources are divided into two types. The first type is a one-time time resource. For example, one symbol transmits one omnidirectional first signal. The other is a non-one-time time resource, for example, a plurality of sets of periodic time resources or discontinuous time resources (which may include start time and end time). The periodic time resources transmit sensing signals in the same direction for each set, and the beam directions in different sets of periodic time resources are different.

[0140] H111. The frequency resource of the sensing signal.

[0141] Optionally, the frequency resource includes the center frequency point of the sensing signal, bandwidth, resource block (RB) or sub-carrier, reference point (Point A), start bandwidth position, etc.

[0142] H112. The quasi co-location (QCL) relationship of the sensing signal.

[0143] For example, the sensing signal includes a plurality of resources, and each resource is QCL with one synchronization signal / physical broadcast channel signal block (or synchronization signal block) (SSB). QCL includes Type A, Type B, Type C or Type D.

[0144] It should be noted that the measured quantity in the embodiments of the present application includes at least one of the following K11 and K12.

[0145] K11. The first type of measured quantity.

[0146] Specifically, the first type of measured quantity is K111. Channel matrix H K112, Received Signal Strength Indicator (RSSI), K113, Reference Signal Received Power (RSRP), K114, 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, Doppler spread, K119, Doppler shift, K120, The phase difference between the sensed signal received by the first antenna and the sensed signal received by the second antenna, K121, The delay difference between the sensed signal received by the first antenna and the sensed 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.

[0147] It should be noted that the characteristic difference may be the phase difference or other differences between the I-channel signal and the Q-channel signal.

[0148] Here, it should be noted that the I-channel signal and the Q-channel signal are the in-phase signal and the quadrature signal respectively, I is in-phase, Q is quadrature, and the phases of the I-channel signal and the Q-channel signal are different by 90 degrees.

[0149] K12, The second type of measurement quantity.

[0150] Specifically, the second type of measurement quantity includes at least one of the following K121, K122, and K123.

[0151] K121, The characteristic information of the target object.

[0152] It should be noted that the feature information of the target object is information that can reflect the attributes or location status 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.

[0153] K122. Related information of the target event.

[0154] 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-reading language recognition, walking posture recognition, facial expression recognition, breathing monitoring, heart rate monitoring, etc.

[0155] K123. Related information of the target environment.

[0156] It should be noted that the related information of the target environment may be at least one of humidity, luminance, temperature and humidity, atmospheric pressure, air quality, weather conditions, terrain and landform, building / vegetation distribution, population statistics, crowd density, vehicle density, etc.

[0157] Optionally, the measurement quantity may further include at least one of the following K21 and K22.

[0158] K21. The position, material, shape and / or type of the reflection point.

[0159] K22. Radar spectrum information.

[0160] Optionally, the measurement quantity is the measurement quantity for each antenna or the measurement quantity for each sensing resource.

[0161] For example, the measurement quantity is the measurement quantity of each antenna (port) on the transmitting side or the receiving side, or the measurement quantity is the measurement quantity at each sensing resource, for example, the measurement quantity of each resource block (RB), subcarrier, or RB group.

[0162] 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 according to the target area, and determines the direction in which the base station transmits the sensing signal.

[0163] Hereinafter, specific use cases for actual application will be described by way of examples as follows.

[0164] Specific use case 1: Base station A transmits a sensing signal, base station B receives the sensing signal, and a third-party application starts a sensing service.

[0165] The network devices involved in this case are as shown in FIG. 5, and the realization process in this case is mainly as follows.

[0166] In step S101, the application server receives the sensing requirement of the third-party application.

[0167] For example, the sensing requirement is to sense a three-dimensional map of the target area (the accuracy / resolution of the map is 5 m), and the target area may be a specified area, for example, the periphery of a certain building, or the peripheral area of the target UE. The sensing requirement may include information of the target area, such as area longitude and latitude (range), etc.

[0168] In step S102, an application server (including an in-network server or an out-of-network server such as an IP Multimedia Subsystem (IMS)) transmits the sensing requirement to a core network (e.g., AMF) or a sensing network function entity / sensing network element of the core network (if it exists). Alternatively, the application server transmits the sensing requirement to the AMF, and the AMF forwards the requirement to the sensing network function entity / sensing network element.

[0169] It should be noted here that the sensing network function entity / sensing network element of the core network exchanges target information (the target information includes a sensing processing request, an interactive sensing capability, interactive sensing auxiliary data, an interactive sensing measurement quantity, or a sensing result) with a target UE or a serving base station of the target UE or a base station related to the target area, and obtains a target sensing result or a sensing measurement quantity (an uplink measurement quantity or a downlink measurement quantity). Furthermore, based on the target area, it can interact with other network elements / functions in the core network to obtain information of base stations that may require information exchange.

[0170] It should be noted here that the core network (or sensing network element) or the application server or other nodes (e.g., AMF) completes the monitoring process. There is a problem of selecting a sensing network element (selected by the AMF) when the AMF forwards the requirement to the sensing network element and multiple sensing network elements can correspond to one AMF.

[0171] The factors considered by the AMF for selecting a sensing network element include at least one of the QoS of the request (e.g., sensing accuracy, response time, sensing QoS level), access type (3GPP (registered trademark) 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 element capabilities, sensing network element traffic load, sensing network element location, indication for single-event notification or multiple-event notification, event notification duration, network slice information, etc.

[0172] In step S103, the core network (or sensing network element) sends the setting information of the sensing requirement or sensing signal to base station A.

[0173] Furthermore, it should be noted that the setting information of the sensing signal may be associated with the sensing requirement, and by only notifying the sensing requirement, the receiving side can determine the setting information of the sensing signal according to the association relationship with the sensing requirement.

[0174] Optionally, as a method of determining the setting information of the sensing signal according to the sensing requirement (e.g., determining the bandwidth size of the sensing signal according to the resolution sensing requirement, etc.), at least one of the following methods can be adopted. In Y11, base station A notifies its sensing capabilities (capabilities related to sending sensing signals, e.g., the maximum bandwidth for sending sensing signals, the maximum transmission power of sensing signals, etc.) to the core network, and / or base station B notifies its sensing capabilities (capabilities related to receiving sensing signals, e.g., the maximum bandwidth for receiving sensing signals, the measurement quantity of supported sensing signals, etc.) to the core network (AMF or sensing network element), and then the core network determines the setting information of the sensing signal according to the sensing requirement. In Y12, the base station determines the setting information of the sensing signal according to the sensing requirement. In Y13, the core network determines the configuration information of some sensing signals, and the base station determines the configuration information of some other sensing signals. In Y14, the core network recommends the configuration information of the sensing signals to the base station according to the sensing demand, and the base station finally determines the configuration information of the sensing signals. In Y15, the base station recommends the configuration information of the sensing signals to the core network according to the sensing demand, and the core network finally determines the configuration information of the sensing signals.

[0175] It should be noted here that as a determination method of base station A, the core network or the sensing network element determines that the relevant base station is base station A according to the target area, and base station A determines the direction in which the sensing signal is transmitted.

[0176] In step S104, the core network (or the 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 demand to base station B (the receiving base station).

[0177] In step S105, the core network (or the sensing network element) or base station A transmits the measurement quantity related to the sensing signal to be measured by base station B (such as the Angle of Arrive (AOA), Angle of Departure (AOD), delay, RSRP, radar spectrum information, etc.) to base station B (the receiving base station), or Without the need for a single signaling instruction, base station B determines the measurement quantity according to the sensing demand (the mapping table from the sensing demand to the measurement quantity).

[0178] In step S106, base station A transmits the sensing signal.

[0179] It should be noted that base station A transmits the sensing signal in the way of beam sweeping.

[0180] In step S107, base station B receives the sensing signal.

[0181] After receiving the sensing signal, the base station B obtains the measured value of the corresponding measurement quantity, and one of the following processing methods can be selected for the measured value.

[0182] Processing method 1: The conversion from the measurement quantity to the sensing result is completed by the core network or the application server.

[0183] In step S108, the base station B transmits the measurement quantity to the core network (or the sensing network element), or the base station B transmits the measurement quantity to the base station A, and the base station A transmits the measurement quantity to the core network (or the sensing network element).

[0184] In step S109, the core network (or the sensing network element) transmits 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 element) determines the sensing result based on the measurement quantity and transmits the sensing result to the application server.

[0185] In step S110, the application server transmits the sensing result to the third-party application.

[0186] Processing method 2: The conversion from the measurement quantity to the sensing result is completed by the base station.

[0187] In step S108, the base station B determines the sensing result based on the measurement quantity and transmits the measurement result to the core network (or the sensing network element).

[0188] In step S109, the core network (or the sensing network element) transmits the sensing result to the application server.

[0189] In step S110, the application server transmits the sensing result to the third-party application.

[0190] Furthermore, in order to assist in the completion of the conversion process, it is necessary to send relevant information of base station A, such as antenna position, synchronization information (single frequency network (SFN) start time), AI-related information (e.g., AI training data), etc., to the node that completes the above conversion.

[0191] Furthermore, it should be further explained that the charging function is completed by the core network or the application server.

[0192] Furthermore, it should be further explained that the sensing signals in the above process may be sent by multiple base stations, and may also be received by multiple base stations. At this time, the core network needs to determine the set of base stations that send the sensing signals and the set of base stations that receive the sensing signals, send the configuration information of the sensing signals of multiple base stations to the corresponding multiple base stations respectively, and send the measurement quantities related to the sensing signals to be measured by the receiving base stations to the corresponding multiple receiving base stations respectively. Optionally, it is necessary to exchange the configuration information of the sensing signals among multiple transmitting base stations (for example, the base station as a coordinator sends the configuration information of the sensing signals to other transmitting base stations and sends the measurement quantities related to the sensing signals to other receiving base stations). In contrast, base station A in the above process may be TRP A, base station B may be TRP B, and TRP A and B belong to the same base station or different base stations.

[0193] Furthermore, it should be further explained that after the first network device receives the sensing requirement or the measurement quantity related to sensing sent from the second network device or the third network device, it can reject the sensing requirement or agree to the sensing requirement.

[0194] Specific use case 2: Base station A sends, base station B receives, and the core network (or network management system or base station) starts the sensing service.

[0195] The realization process in this case is mainly as follows.

[0196] In step S201, the core network AMF sends the sensed demand or the configuration information of the sensing signal to the sensing network function entity / sensing network element. For example, the sensed demand is to sense a three-dimensional map of the target area (the accuracy / resolution of the map is 5 m), and the target area may be a specified area, such as the periphery of a certain building, or the peripheral area of the target UE. The sensed demand may include information about the target area, such as information on area longitude and latitude (range), etc. Alternatively, the AMF receives the configuration information of the sensed demand or the sensing signal sent from the network management system and forwards it to the sensing network element. Alternatively, the AMF receives the configuration information of the sensed demand or the sensing signal sent from the base station and forwards it to the sensing network element (it should be noted that the configuration information of the sensed demand or the sensing signal of base station A can be directly sent to base station B without being sent to the core network).

[0197] In step S202, the sensing network function entity / sensing network element sends the configuration information of the sensed demand or the sensing signal to base station A (or the AMF sends the configuration information of the sensed demand or the sensing signal to base station A). Alternatively, the configuration information of the sensing signal is associated with the sensed demand, and only the sensed demand is notified. The receiving side can determine the configuration information of the sensing signal based on the association relationship with the sensed demand.

[0198] Optionally, for the implementation form of determining the configuration information of the sensing signal according to the sensed demand (for example, determining the bandwidth of the sensing signal according to the resolution sensed demand), specific use case 1 can be referred to.

[0199] In step S203, the core network (or the sensing network element) or base station A sends the configuration information of the sensing signal (including time-frequency information, sequence information, etc.) or the sensed demand to base station B (the receiving base station).

[0200] In step S204, the core network (or sensing network element) or base station A transmits the measurement quantity related to the sensing signal (for example, AOA, AOD, delay, RSRP, radar spectrum information, etc.) to base station B (the receiving base station), or Without requiring a single signaling instruction, base station B determines the measurement quantity according to the sensing demand (a mapping table from the sensing demand to the measurement quantity).

[0201] In step S205, base station A transmits the sensing signal.

[0202] It should be noted that base station A transmits the sensing signal in the manner of beam sweeping.

[0203] In step S206, base station B receives the sensing signal.

[0204] After receiving the sensing signal, base station B obtains the measured value of the corresponding measurement quantity, and one of the following processing methods can be selected for the measured value.

[0205] Processing method 1: The conversion from the measurement quantity to the sensing result is completed by the core network.

[0206] In step S207, base station B transmits the measurement quantity to the core network (AMF or sensing network element), or Base station B transmits the measurement quantity to base station A, and base station A transmits the measurement quantity to the core network (AMF or sensing network element).

[0207] In step S208, the core network (AMF or sensing network element) converts the measurement quantity into a sensing result, If the sensing demand of the core network is from the network management system, the core network transmits the sensing result to the network management system, or the core network transmits the measurement quantity to the network management system, and the network management system converts the measurement quantity into a sensing result. If the sensing requirement of the core network is from the base station, the core network transmits the sensing result to the base station.

[0208] Processing method 2: The conversion from the measurement quantity to the sensing result is completed at the base station.

[0209] In step S207, base station B determines the sensing result based on the measurement quantity and transmits the measurement result to the core network (AMF or sensing network element). If the sensing requirement of the core network is from the network management system, the core network transmits the sensing result to the network management system. If the sensing requirement of the core network is from the base station, the core network transmits the sensing result to the base station.

[0210] It should be noted that in order to assist in the completion of the conversion process, it is necessary to transmit the relevant information of base station A, such as antenna position, synchronization information (SFN start time), AI-related information, etc., to the node that completes the above conversion.

[0211] Here, it should be noted that if the sensing network function entity / sensing network element is arranged at the base station, as an optional means, the sensing service may be performed without passing through the core network at all.

[0212] Furthermore, it should be noted that the sensing signals in the above process may be transmitted by multiple base stations, and multiple base stations may also receive the sensing signals.

[0213] At this time, the core network needs to determine a set of base stations that transmit sensing signals and a set of base stations that receive sensing signals, send the configuration information of the sensing signals of multiple base stations to the corresponding multiple base stations respectively, and send the measurement quantities related to the sensing signals to be measured by the receiving base stations to the corresponding multiple receiving base stations respectively. Optionally, it is necessary to exchange the configuration information of the sensing signals among multiple transmitting base stations (for example, the base station acting as a coordinator sends the configuration information of the sensing signals to other transmitting base stations and sends the measurement quantities related to the sensing signals to other receiving base stations). In contrast, base station A during the above process may be TRP A, base station B may be TRP B, and TRP A and B belong to the same base station or different base stations.

[0214] Furthermore, it should be further explained that after the first network device receives the sensing requirement or the measurement quantity related to sensing sent from the second network device or the third network device, it can reject the sensing requirement or agree to the sensing requirement.

[0215] Specific use case 3: Base station A transmits a sensing signal, base station B receives the sensing signal, and the UE starts a sensing service.

[0216] The realization process in this case is mainly as follows.

[0217] In step S301, the UE sends a sensing request or the configuration information of the sensing signal to the AMF through NAS signaling.

[0218] For example, the sensing requirement is to sense a three-dimensional map of the target area (the accuracy / resolution of the map is 5 m), and the target area may be a specified area, such as the periphery of a certain building, or the peripheral area of the target UE. The sensing requirement may include information of the target area, such as information on the area longitude and latitude (range), etc.

[0219] In step S302, the AMF sends the sensed demand or the configuration information of the sensed signal to the sensing network function entity / sensing network element.

[0220] In step S303, the sensing network function entity / sensing network element sends the sensed demand or the configuration information of the sensed signal to base station A (or the AMF sends the sensed demand or the configuration information of the sensed signal to base station A). Alternatively, the configuration information of the sensed signal is associated with the sensed demand, and only the sensed demand is notified, and the receiving side can determine the configuration information of the sensed signal based on the association with the sensed demand.

[0221] Optionally, the step of determining the configuration information of the sensed signal based on the sensed demand (for example, determining the bandwidth size of the sensed signal based on the resolution sensed demand, etc.) mainly includes at least one of the following several methods. In Y21, base station A notifies its sensing capabilities (capabilities related to sending sensed signals, such as the maximum bandwidth for sending sensed signals, the maximum transmission power of sensed signals, etc.) to the core network (AMF or sensing network element), and / or base station B notifies its sensing capabilities (capabilities related to receiving sensed signals, such as the maximum bandwidth for receiving sensed signals, the measurement quantity of supported sensed signals, etc.) to the core network, and then the core network determines the configuration information of the sensed signal based on the sensed demand. In Y22, the base station determines the configuration information of the sensed signal based on the sensed demand. In Y23, the core network determines the configuration information of some sensed signals, and the base station determines the configuration information of other some sensed signals. In Y24, the core network recommends the configuration information of the sensed signal to the base station based on the sensed demand, and the base station finally determines the configuration information of the sensed signal. In Y25, the base station recommends the configuration information of the sensed signal to the core network based on the sensed demand, and the core network finally determines the configuration information of the sensed signal. In Y26, the UE recommends the configuration information of the sensed signal to the base station based on the sensed demand, and the base station finally determines the configuration information of the sensed signal. In Y27, the UE recommends the setting information of the sensing signal to the core network according to the sensing requirement, and the core network finally determines the setting information of the sensing signal. In Y28, the UE determines the setting information of the sensing signal according to the sensing requirement.

[0222] In step S304, the core network (or sensing network element) or base station A transmits the signal setting information (including time-frequency information, sequence information, etc.) or sensing requirement to base station B (receiving base station).

[0223] In step S305, the core network (or sensing network element) or base station A transmits the measurement quantity related to the sensing signal (for example, AOA, AOD, delay, RSRP, radar spectrum information, etc.) to base station B (receiving base station), or Without the need for a separate signaling instruction, base station B determines the measurement quantity according to the sensing requirement (mapping table from sensing requirement to measurement quantity).

[0224] In step S306, base station A transmits the sensing signal.

[0225] It should be noted that base station A transmits the sensing signal in the way of beam sweeping.

[0226] In step S307, base station B receives the sensing signal.

[0227] After receiving the sensing signal, base station B obtains the measured value of the corresponding measurement quantity, and one of the following processing methods can be selected for the measured value.

[0228] Processing method 1: The conversion from the measurement quantity to the sensing result is completed by the core network.

[0229] In step S308, base station B transmits the measurement quantity to the core network (AMF or sensing network element), or The base station B transmits the measurement quantity to the base station A, and the base station A transmits the measurement quantity to the core network (AMF or sensing network element).

[0230] In step S309, the core network (AMF or sensing network element) determines the sensing result based on the measurement quantity.

[0231] In step S310, the core network (AMF or sensing network element) transmits the sensing result to the UE (by NAS signaling).

[0232] Processing method 2: The conversion from the measurement quantity to the sensing result is completed at the base station B.

[0233] In step S308, the base station B determines the sensing result based on the measurement quantity and transmits the measurement result to the core network (AMF or sensing network element).

[0234] In step S309, the core network (AMF or sensing network element) transmits the sensing result to the UE (by NAS signaling).

[0235] Processing method 3: The conversion from the measurement quantity to the sensing result is completed at the UE.

[0236] In step S308, the base station B transmits the measurement quantity to the core network (or sensing network element).

[0237] In step S309, the core network (AMF or sensing network element) transmits the measurement quantity to the UE (by NAS signaling).

[0238] In step S310, the UE determines the sensing result based on the measurement quantity.

[0239] Here, it should be noted that in order to assist in the completion of the conversion process, it is necessary to send the relevant information of base station A, such as antenna position, synchronization information (SFN start time), AI-related information, etc., to the node that completes the above conversion.

[0240] Furthermore, it should be noted that the sensing signals in the above process may be those transmitted by multiple base stations, and the sensing signals may also be received by multiple base stations.
