[0040] The following is a brief description of the technical content related to this application.

[0041] 1. Communication and perception integration / synaesthesia integration:

[0042] Future wireless communication systems, including beyond 5G (B5G) and sixth-generation mobile networks (6G), are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. Integrated Sensing and Communication (ISAC) enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems, supporting many important application scenarios. Typical applications of ISAC include navigation and obstacle avoidance for autonomous vehicles, indoor positioning and activity recognition based on Wi-Fi, communication and sensing for unmanned aerial vehicles, extended reality (XR), and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0043] ISAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0044] At present, typical communication perception integration scenarios that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in Table 1.

[0045] Table 1 Typical scenarios of communication perception integration

[0046] There are six basic sensing modes, depending on the difference between the sending and receiving nodes of the sensing signal, as shown in Figure 2:

[0047] (1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0048] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0049] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0050] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0051] (5) Terminal self-transmitting and self-receiving perception: Terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0052] (6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurements.

[0053] It's worth noting that each sensing method in Figure 2 uses one sensing signal transmitting node and one sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more sensing signal transmitting nodes and one or more sensing signal receiving nodes. The sensing targets in Figure 2 use people and vehicles as examples, assuming neither person nor vehicle carries or has installed signal transceiver / receiver equipment. In actual scenarios, the range of sensing targets will be much richer.

[0054] 2. Feasibility Study of Synaesthesia Integration

[0055] 3GPP TR 22.837 describes 32 perception use cases for synaesthesia fusion, including intruder detection in smart homes, environmental intruder detection in smart homes, home health monitoring, motion monitoring, gesture recognition for application navigation and immersive interaction, and immersive experiences such as perception-based XR. These use cases involve the perception of user private areas or privacy information such as user vital signs.

[0056] At the same time, 22.837 also clearly raises considerations for privacy in Chapter 6. Due to the introduction of sensing technology, privacy is no longer limited to the privacy of the transmitting UE, but also involves the privacy of people or objects that are not carrying the UE.

[0057] The following, in combination with the accompanying drawings, describes in detail the sensing method, sensing device, communication equipment and readable storage medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0058] Considering the privacy requirements related to perception in synaesthesia fusion, please refer to FIG3 . An embodiment of the present application provides a perception method, including:

An example implementation is that the sensing function is one of the core network functions, responsible for sensing control and / or sensing data processing.

[0066] In an embodiment of the present application, the first device sends a first indication message, and the first indication message is used to indicate that the first perception data of the perception service requested by the first device is generated or processed by a designated device, so that the perception data of the perception service can be generated or processed on the designated device according to user needs, thereby avoiding perception data leakage, improving the security of user data, and protecting user privacy.

Optionally, the perception request message also includes the Internet Protocol (IP) address of the first device. One implementation method is that the source address in the IP header of the perception request message indicates the IP address of the first device, or a certain information unit in the perception request message indicates the IP address of the first device.

[0068] In an embodiment of the present application, optionally, the first perception data includes at least one of the following types: perception measurement data, perception auxiliary data, and perception results.

[0069] Optionally, the perception assistance data is data that assists in generating the required perception result, and may include at least one of the following: the location of the UE that sends or receives the perception signal, an environment map, target area information, etc.

[0070] Perception measurement data and perception results may also be collectively referred to as perception measurement reports. Perception measurement data and perception results may also be defined using perception measurement quantities.

[0071] One potential classification method is to classify the perception measurement quantities into the following four categories (this description focuses on describing the specific content of the perception measurement quantities. The perception measurement quantities may also be classified into three categories or unclassified, and the four categories are only examples and are not limited thereto). Based on the relationship between the perception measurement quantities and the perception services, the measurement results of the following first-level measurement quantities and / or second-level measurement quantities are also referred to as perception measurement data, and the third-level measurement quantities and / or fourth-level measurement quantities are also referred to as perception results.

[0072] a) First-level measurement quantity (also called received signal / original channel information), including at least one of the following: complex result of received signal / channel response, amplitude / phase, I-channel / Q-channel and operation results thereof (the operation includes at least one of the following: addition, subtraction, multiplication, division, matrix addition, subtraction, multiplication, matrix transposition, trigonometric operation, square root operation, and power operation, as well as threshold detection results and maximum / minimum value extraction results of the above operation results; optionally, the operation also includes at least one of the following: Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT) / Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform and digital filtering, as well as threshold detection results and maximum / minimum value extraction results of the above operation results);

[0074] c) Level 3 measurements (also called basic attributes / states), including at least one of the following: distance, velocity, angle / direction, radar cross section (RCS), and acceleration;

[0076] In this embodiment of the present application, optionally, the first indication information includes at least one of the following:

[0077] 1) indication information used to indicate whether the perception service requested by the first device requires privacy protection;

[0078] 2) the designated equipment;

[0079] In this embodiment of the present application, the designated device may be one or more. For example, the designated device includes: multiple UEs of a user in a home environment or UEs of different family members. Optionally, the first indication information may include a list of designated device identifiers (e.g., mobile phone numbers, IP addresses, etc.).

[0080] Optionally, the designated device includes the first device that sends the perception request, or other devices associated with the perception request.

[0081] In an embodiment of the present application, optionally, the designated device includes at least one of a terminal, a base station, and a perception function.

[0082] In order for the first perception data to be generated or processed by the designated device, the designated device may be at least one of the following during the perception process:

[0083] A node that generates a perception result based on the perception measurement data;

[0084] Sensing signal receiving node;

[0085] Sensing signal sending node;

[0086] A node that provides perception assistance data.

[0087] 3) the designated device and sensing method;

[0088] In the embodiment of the present application, optionally, the sensing method includes at least one of the following:

[0089] The designated device autonomously sends and receives sensing signals;

[0090] The designated device sends a perception signal, and other devices other than the designated device receive the perception signal;

[0091] The designated device receives the perception signal, and other devices other than the designated device send the perception signal.

[0092] For example, the first indication information indicates that: the sensing signal receiving node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0093] Alternatively, the first indication information indicates that: the perception signal receiving node is a designated device and the perception mode is receiving the perception signal by the designated device and sending the perception signal to other devices other than the designated device;

[0094] Alternatively, the first indication information indicates that: the sensing signal sending node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0095] Alternatively, the first indication information indicates that: the perception signal sending node is a designated device and the perception mode is that the designated device sends the perception signal and other devices other than the designated device receive the perception signal.

[0096] 4) Type of the first perception data;

[0097] 5) a privacy protection level, where the privacy protection level indicates the type of the first perception data, and different privacy protection levels correspond to different types of first perception data;

[0099] 7) Encryption configuration information of the sensing signal;

[0100] 8) Instruction information for indicating whether the perception result needs to be sent encrypted;

[0101] 9) Configuration of encryption algorithm for perception results.

[0102] Optionally, the encryption algorithm is, for example, Advanced Encryption Standard (AES), SNOW 3G word-oriented stream cipher algorithm, or Zu Chongzhi encryption algorithm (ZUC).

[0103] In an embodiment of the present application, optionally, the privacy protection level includes at least one of the following:

[0104] The first privacy protection level (also referred to as level 1 or first level, etc., is only used to illustrate the number and the name is not limited to this). The first privacy protection level is used to indicate that the perception result is generated or processed by a specified device; that is, the perception result is generated or processed on the specified device, that is, the required perception result based on the perception measurement data is completed on the specified device.

[0105] The second privacy protection level (also referred to as level 2 or level 2, etc.) indicates that the perception assistance data and perception results are generated or processed by a designated device. Perception results are typically generated in conjunction with the location of the UE sending or receiving the perception signal, or perception assistance data such as an environmental map. While the first privacy protection level may allow other devices that obtain the perception assistance data to calculate the corresponding perception results, the second privacy protection level excludes the perception assistance data from the designated device. This further reduces the probability of non-designated devices obtaining the perception results when perception results based on the perception assistance data are required.

[0106] The third privacy protection level (also referred to as level 3 or level 3) indicates that the perception measurement data and perception results are generated or processed by a designated device. This means that the perception measurement data is generated or processed on the designated device. When non-designated devices cannot obtain the perception measurement data, the probability of non-designated devices obtaining the perception results and related information is further reduced compared to the first privacy protection level.

[0107] The fourth privacy protection level (also referred to as level 4 or fourth level, etc.) is used to indicate that the perception assistance data, perception measurement data and perception results are generated or processed by a designated device; this means that the perception assistance data, perception measurement data and perception results are all generated or processed on the designated device.

[0108] The fifth privacy protection level (also referred to as level 5 or level 5, etc.) indicates that the perception-assisted data, perception-measurement data, and perception results are generated or processed by a designated device, and that the perception mode is that the designated device autonomously transmits and receives perception signals. This autonomous transmission and reception of perception signals by designated devices helps avoid the risk of leakage of perception-assisted data, perception-measurement data, or perception results due to leakage of perception information by non-designated devices when transmitting or receiving between non-designated devices and designated devices.

[0109] In an embodiment of the present application, optionally, the perception measurement data includes at least one of the following: real perception measurement data and encrypted perception measurement data, and the third privacy protection level includes at least one of the following:

[0110] The first sub-level (also known as level 3-1, etc.) indicates that the actual perception measurement data and results are generated or processed by a designated device. One implementation involves designating the designated device as a perception signal receiving node, so that the perception measurement data is generated and processed by the designated device and not transmitted to other devices. Alternatively, the designated device is a perception signal receiving node, and the perception signal transmitting node is configured to send the perception signal in an encrypted manner, thereby preventing other nodes that can receive the signal from obtaining the actual perception measurement data.

[0111] The second sublevel (also known as level 3-2, etc.) indicates that real perception measurement data, encrypted perception measurement data, and perception results are generated or processed by designated devices. In one implementation, the designated device is the sensing signal sending node, and the sensing signal is sent in an encrypted manner, so that only the designated device can obtain the real perception measurement data.

[0112] In this embodiment of the present application, optionally, the perception measurement data includes first perception measurement data (also referred to as a first perception measurement quantity) and second perception measurement data (also referred to as a second perception measurement quantity), the perception result includes a first perception result (also referred to as a third perception measurement quantity) and a second perception result (also referred to as a fourth perception measurement quantity), and the third privacy protection level includes at least one of the following:

[0113] a third sublevel (or referred to as level 3-1, etc.), the third sublevel being used to indicate that the first perception measurement data, the first perception result, and the second perception result are generated or processed by a designated device;

[0114] a fourth sublevel (or referred to as level 3-2, etc.), the fourth sublevel being used to indicate that the first perception measurement data, the second perception measurement data, the first perception result, and the second perception result are generated or processed by a designated device;

[0115] a fifth sublevel (or referred to as level 3-3, etc.), the fifth sublevel being used to indicate that the first perception measurement data and the first perception result are generated or processed by a designated device;

[0116] The sixth sublevel (or referred to as level 3-4, etc.) is used to indicate that the first perception measurement data, the second perception measurement data, and the first perception result are generated or processed by a designated device.

[0117] Optionally, the first perception measurement data contains more information than the second perception measurement data, and thus the first perception measurement data has a higher risk of being abused or having its privacy leaked if provided to other devices.

[0118] Optionally, the first perception result contains more information than the second perception result, and thus the first perception result has a higher risk of being abused or having its privacy leaked if provided to other devices.

[0119] In this embodiment of the present application, optionally, the fourth privacy protection level includes at least one of the following:

[0120] The seventh sublevel (or referred to as level 4-1, etc.) is used to indicate that the actual perception measurement data, perception auxiliary data, and perception results are generated or processed by a designated device;

[0121] The eighth sublevel (or referred to as level 4-2, etc.) is used to indicate that the real perception measurement data, encrypted perception measurement data, perception assistance data, and perception results are generated or processed by a designated device.

[0122] In this embodiment of the present application, optionally, the fifth privacy protection level includes at least one of the following:

[0123] The ninth sublevel (also known as level 5-1, etc.) is used to indicate that the actual perception measurement data, perception auxiliary data, and perception results are generated or processed by a designated device, and the perception mode is that the designated device autonomously transmits and receives perception signals.

[0124] The tenth sublevel (or level 5-2, etc.) is used to indicate that the real perception measurement data, encrypted perception measurement data, perception auxiliary data and perception results are generated or processed by the designated device, and the perception method is that the designated device spontaneously sends and receives perception signals.

[0125] In an embodiment of the present application, optionally, the perception method further includes: the first device reporting perception capabilities, the perception capabilities including the first device having the ability to generate perception results based on perception measurement data, so that the second device can determine, based on the perception capabilities of the first device, that the first device is a designated device that generates perception results based on perception measurement data. Since the ability of the first device to generate perception results based on perception measurement data is usually closely related to the storage and computing capabilities of the first device, it can be characterized by reporting perception capabilities. The perception results may be perception results related to the user's vital signs or the user's private areas. Optionally, the perception results may include at least one of the following: respiratory rate, intrusion detection, gesture recognition, and motion monitoring, etc.

[0126] In an embodiment of the present application, optionally, the first device is a node that generates a perception result based on perception measurement data, and the perception method further includes: the first device receives perception data auxiliary processing information, and the perception data auxiliary processing information is used to assist the first device in generating a perception result.

[0127] Optionally, before the first device receives the perception data auxiliary processing information, the method further includes: the first device sends a perception data auxiliary processing request, where the perception data auxiliary processing request is used to request the perception data auxiliary processing information.

[0128] Optionally, the perception data auxiliary processing information includes at least one of the following: a perception algorithm indication (such as an AI model identifier), base station location information, etc.

[0129] In an embodiment of the present application, optionally, the perception method further includes: the first device reports perception authorization information, and the perception authorization information includes at least one of the following: an identifier of the application function that is allowed to request the perception service (such as the APP name or IP address port number, etc.), the type of perception service that the application function is allowed to request, and the type of perception data that the application function is allowed to request. The application function includes at least one of the UE application function and the network-side application function. Optionally, the information contained in the perception authorization information is related to the user's vital signs or private areas. For example, health monitoring APP 1 is allowed to request perception results / perception service type 1 (such as respiratory monitoring) in area A (such as a private room).

[0130] In the embodiment of the present application, optionally, the first device is a perception signal sending node, and the perception method in the embodiment of the present application further includes the following steps:

[0131] The first device generates a first sensing signal;

[0132] The first device encrypts the first perception signal to generate a first target perception signal;

[0133] The first device sends the first target perception signal;

[0134] The first device receives encrypted perception measurement data based on the first target perception signal;

[0135] The first device decrypts the encrypted perception measurement data to obtain real perception measurement data.

[0136] An example of a perception signal encryption method is when the required perception result includes at least one of range / delay and speed / Doppler. The perception signal encryption method may be: after the perception signal transmitting node generates a first perception signal based on the configuration information of the traditional perception signal, it encrypts the first perception signal to generate a first encrypted signal, and multiplies the first encrypted signal by the first perception signal (equivalent to performing a phase rotation on the first perception signal) to obtain a first target perception signal. The generation method of the first encrypted signal is determined by the UE.

[0137] The first perception signal at each moment corresponds to a first encrypted signal, each first encrypted signal includes m elements (the number of elements included in each first encrypted signal is the same as the number of elements included in each first perception signal), and the multiplication of the first perception signal and the first encrypted signal can be a frequency domain multiplication or conjugate multiplication of the first perception signal and the first encrypted signal corresponding to each same moment. Specifically, the following situations are included:

[0138] a) The first perception signal is phase-rotated only in the frequency domain by the first encrypted signal, and the distance / delay information can be encrypted at this time; for example, the perception signal sending node generates the first perception signal r(m) at the current moment, where m=0, 1, 2…, M-1 corresponds to the frequency domain sampling point or subcarrier number. The first perception signal is encrypted using a pseudo-random sequence (Pseudo-Noise, PN) sequence based on Quadrature Phase Shift Keying (QPSK) modulation to generate a first encrypted signal r1(m), where m=0, 1, 2…, M-1 corresponds to the frequency domain sampling point or subcarrier number. One way to generate the first encrypted signal is the same as the way to generate the first perception signal, using a PN sequence. However, the PN sequence generation initialization factor is determined and configured by the UE. When this encryption method is used, the encryption configuration information is the PN sequence generation initialization factor.

[0139] b) performing a phase rotation on the first sensing signal only in the time domain using the first encrypted signal, thereby encrypting the velocity / Doppler information;

[0140] c) Phase rotation is performed on the first sensing signal in the frequency domain and the time domain using the first encrypted signal, so that the distance / delay information and the speed / Doppler information can be encrypted.

[0143] The first device receives the encrypted perception signal, and decrypts and performs perception measurement on the encrypted perception signal according to at least one of the first encryption indication information and the encryption configuration information of the perception signal to obtain real perception measurement data.

[0144] In some other embodiments of the present application, the first encryption indication information may also indicate whether the perception signal is sent in an encrypted manner.

[0145] The encryption configuration information of the perception signal may include, for example, PN sequence generation initialization factor information, etc.

[0146] In an embodiment of the present application, optionally, the first device is a node that generates a perception result based on perception measurement data, and the perception method in the embodiment of the present application further includes the following steps:

[0147] The first device generates a first perception result based on the perception measurement data;

[0148] The first device encrypts the first sensing result to generate a third encrypted signal;

[0149] The first device sends the third encrypted signal.

[0150] In an embodiment of the present application, if the first device performs perception measurement and perception result processing, the delay for the first device (such as a vehicle or unmanned aerial vehicle (UAV) is a UE with communication function) to obtain the perception result can also be shortened to meet high real-time perception scenarios such as vehicle autonomous driving or UAV collision avoidance.

[0155] That the perception data of the requested perception service does not leave the designated device means that the perception data is generated or processed on the designated device.

[0156] In an embodiment of the present application, optionally, the second device receives the first indication information sent by the first device. Optionally, the first device may include at least one of the following: a UE modem, a UE application function (AF), and an application function (such as an application server).

[0157] Step 42: The second device determines, based on the first indication information, a perception mode and at least one of the perception nodes serving as the designated device, where the perception node includes at least one of the following: a perception function node, a perception signal sending node, a perception signal receiving node, and a perception measurement data processing node.

[0158] In an embodiment of the present application, the second device determines the perception node as the designated device based on the received first indication information, so that the perception data of the perception service can be generated or processed on the designated device according to user needs, avoiding the leakage of perception data, improving the security of user data, and protecting user privacy.

[0165] Optionally, the designated device includes the first device that sends the perception request, or other devices associated with the perception request.

[0166] In an embodiment of the present application, optionally, the designated device includes at least one of a terminal, a base station, and a perception function.

[0167] In order for the first perception data to be generated or processed by the designated device, the designated device may be at least one of the following during the perception process:

[0168] A node that generates a perception result based on the perception measurement data;

[0169] Sensing signal receiving node;

[0170] Sensing signal sending node;

[0171] A node that provides perception assistance data.

[0172] 3) the designated device and sensing method;

[0173] In the embodiment of the present application, optionally, the sensing method includes at least one of the following:

[0174] The designated device autonomously sends and receives sensing signals;

[0175] The designated device sends a perception signal, and other devices other than the designated device receive the perception signal;

[0176] The designated device receives the perception signal, and other devices other than the designated device send the perception signal.

[0177] For example, the first indication information indicates that: the sensing signal receiving node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0178] Alternatively, the first indication information indicates that: the perception signal receiving node is a designated device and the perception mode is receiving the perception signal by the designated device and sending the perception signal to other devices other than the designated device;

[0179] Alternatively, the first indication information indicates that: the sensing signal sending node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0180] Alternatively, the first indication information indicates that: the perception signal sending node is a designated device and the perception mode is that the designated device sends the perception signal and other devices other than the designated device receive the perception signal.

[0181] 4) Type of the first perception data;

[0182] 5) a privacy protection level, where the privacy protection level indicates the type of the first perception data, and different privacy protection levels correspond to different types of first perception data;

[0183] 6) Indication information for indicating whether the perception signal needs to be sent encrypted;

[0184] 7) Encryption configuration information of the sensing signal;

[0185] 8) Instruction information for indicating whether the perception result needs to be sent encrypted;

[0186] 9) Configuration of encryption algorithm for perception results.

[0187] Optionally, the encryption algorithm is, for example, Advanced Encryption Standard (AES), SNOW 3G word-oriented stream cipher algorithm, or Zu Chongzhi encryption algorithm (ZUC).

[0188] In an embodiment of the present application, optionally, the privacy protection level includes at least one of the following:

[0189] The first privacy protection level (also referred to as level 1 or first level, etc., is only used to illustrate the number and the name is not limited to this).

[0190] The second privacy protection level (also referred to as level 2 or level 2, etc.) indicates that the perception assistance data and perception results are generated or processed by a designated device. Perception results are typically generated in conjunction with the location of the UE sending or receiving the perception signal, or perception assistance data such as an environmental map. While the first privacy protection level may allow other devices that obtain the perception assistance data to calculate the corresponding perception results, the second privacy protection level excludes the perception assistance data from the designated device. This further reduces the probability of non-designated devices obtaining the perception results when perception results based on the perception assistance data are required.

[0191] The third privacy protection level (also referred to as level 3 or level 3) indicates that the perception measurement data and perception results are generated or processed by a designated device. This means that the perception measurement data is generated or processed on the designated device. When non-designated devices cannot obtain the perception measurement data, the probability of non-designated devices obtaining the perception results and related information is further reduced compared to the first privacy protection level.

[0193] The fifth privacy protection level (also referred to as level 5 or level 5, etc.) indicates that the perception-assisted data, perception-measurement data, and perception results are generated or processed by a designated device, and that the perception mode is that the designated device autonomously transmits and receives perception signals. This autonomous transmission and reception of perception signals by designated devices helps avoid the risk of leakage of perception-assisted data, perception-measurement data, or perception results due to leakage of perception information by non-designated devices when transmitting or receiving between non-designated devices and designated devices.

[0201] The sixth sublevel is used to indicate that the first perception measurement data, the second perception measurement data, and the first perception result are generated or processed by a designated device.

[0202] Optionally, the first perception measurement data contains more information than the second perception measurement data, and thus the first perception measurement data has a higher risk of being abused or having its privacy leaked if provided to other devices.

[0203] Optionally, the first perception result contains more information than the second perception result, and thus the first perception result has a higher risk of being abused or having its privacy leaked if provided to other devices.

[0204] In this embodiment of the present application, optionally, the fourth privacy protection level includes at least one of the following:

[0205] A seventh sublevel, which is used to indicate that the actual perception measurement data, perception auxiliary data, and perception results are generated or processed by a designated device;

[0206] An eighth sublevel is used to indicate that the real perception measurement data, the encrypted perception measurement data, the perception assistance data, and the perception result are generated or processed by a designated device.

[0220] The following describes the sensing method of this application with examples in combination with specific application scenarios.

[0221] Example 1: Perception request initiated by UE modem

[0222] This embodiment describes that the first device sending the sensing request is a UE modem (hereinafter referred to as UE). The specific process is described as follows:

[0223] Step 1: The UE sends a perception request message to a network-side device (such as an AMF), where the perception request message includes first indication information. Optionally, the perception request message may also include at least one of the following: service type and service requirements. The service type may include, for example, dynamic maps, vehicle speed detection, vehicle tracking, and emergency notifications. The service requirements may include, for example, at least one of the following: perception resolution, perception accuracy, frame rate, duration, target area information, latency, and perceived target information (such as vehicle type, vehicle identification, and location information).

[0224] Optionally, the first indication information includes one of the following:

[0225] 1) indication information used to indicate whether the perception service requested by the first device requires privacy protection;

[0226] 2) the designated equipment;

[0227] Optionally, the designated device includes a UE that sends the perception request, or other devices associated with the perception request.

[0228] In an embodiment of the present application, optionally, the designated device includes at least one of a terminal, a base station, and a perception function.

[0229] In order for the first perception data to be generated or processed by the designated device, the designated device may be at least one of the following during the perception process:

[0230] A node that generates a perception result based on the perception measurement data;

[0231] Sensing signal receiving node;

[0232] Sensing signal sending node;

[0233] A node that provides perception assistance data.

[0234] 3) the designated device and sensing method;

[0235] In the embodiment of the present application, optionally, the sensing method includes at least one of the following:

[0236] The designated device autonomously sends and receives sensing signals;

[0237] The designated device sends a perception signal, and other devices other than the designated device receive the perception signal;

[0238] The designated device receives the perception signal, and other devices other than the designated device send the perception signal.

[0239] For example, the first indication information indicates that: the sensing signal receiving node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0240] Alternatively, the first indication information indicates that: the perception signal receiving node is a designated device and the perception mode is receiving the perception signal by the designated device and sending the perception signal to other devices other than the designated device;

[0241] Alternatively, the first indication information indicates that: the sensing signal sending node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0242] Alternatively, the first indication information indicates that: the perception signal sending node is a designated device and the perception mode is that the designated device sends the perception signal and other devices other than the designated device receive the perception signal.

[0243] 4) Type of the first perception data;

[0244] 5) a privacy protection level, where the privacy protection level indicates the type of the first perception data, and different privacy protection levels correspond to different types of first perception data;

[0245] 6) Indication information for indicating whether the perception signal needs to be sent encrypted;

[0246] 7) Encryption configuration information of the sensing signal;

[0247] 8) Instruction information for indicating whether the perception result needs to be sent encrypted;

[0248] 9) Configuration of encryption algorithm for perception results.

[0249] Note: The subsequent process is described using the example of the designated device being the UE that sends the perception request. In other embodiments of the present application, the designated device may also include multiple UEs, such as multiple UEs of a user in a home environment or UEs belonging to different family members. If the designated device includes multiple UEs, the network-side device needs to determine the perception node based on the perception authorization information of the other UEs. The process of determining the perception node based on the perception authorization information is described in Example 3.

[0250] Step 2: The network side device (such as AMF) selects the appropriate sensing function (SF) according to the target area information or the target UE location information. An example of implementation is that the sensing function is one of the core network functions, responsible for sensing control and / or sensing data processing. SF can register its service area to the Network Repository Function (NRF), and then AMF can select SF by querying NRF and send a sensing request message to SF. If the location management function (LMF) is co-located with SF, then AMF selects LMF (SF) and sends a sensing request message to LMF (SF).

[0251] Step 3: The SF receives the sensing request message and determines the sensing mode and sensing node based on the first indication information in the sensing request message. If the first indication information specifies a device or sensing mode, but the SF cannot configure the specified device or sensing mode, the SF may send a message to reject the sensing request. Optionally, the rejection message of the sensing request carries a rejection reason, which includes the failure to meet the requirements of the first indication information. If the SF continues to perform sensing, the SF shall determine the sensing mode and sensing node based on the first indication information, for example:

[0252] If the first indication information in the perception request message indicates that the UE sending the perception request message is a perception signal sending node, then the SF first determines that the UE is a perception signal sending node, then determines the perception method, and determines whether it is necessary to determine a device other than the UE sending the perception request message as a perception signal receiving node based on the perception method.

[0253] If the first indication information in the perception request message indicates that the UE sending the perception request message is a perception signal receiving node, then the SF first determines that the UE is a perception signal receiving node, then determines the perception method, and determines whether it is necessary to determine a device other than the UE sending the perception request as a perception signal sending node based on the perception method.

[0254] If the first indication information in the perception request message indicates that the UE sending the perception request message is a perception signal sending node or a perception signal receiving node, when the perception mode is a perception signal transmission and reception mode between the UE and other devices, the SF should select a device other than the UE as a perception signal receiving node or a perception signal sending node according to the corresponding perception mode; when the perception mode is that the UE transmits and receives the data autonomously, the SF does not need to determine the perception signal sending node and the perception signal receiving node.

[0255] Optionally, when the first indication information includes that the perception signal receiving node is a designated device, the UE may further indicate, through the first indication information, whether the perception signal is sent in an encrypted manner. If the perception signal is sent in an encrypted manner, the first indication information may further include encryption configuration information for the perception signal. The encryption configuration information for the perception signal may be carried by the aforementioned perception request message or by other messages.

[0256] An example of a perception signal encryption method is when the required perception result includes at least one of range / delay and speed / Doppler. The perception signal encryption method may be: after the perception signal transmitting node generates a first perception signal based on the configuration information of the traditional perception signal, it encrypts the first perception signal to generate a first encrypted signal, and multiplies the first encrypted signal by the first perception signal (equivalent to performing a phase rotation on the first perception signal) to obtain a first target perception signal. The generation method of the first encrypted signal is determined by the UE.

[0257] The first perception signal at each moment corresponds to a first encrypted signal, each first encrypted signal includes m elements (the number of elements included in each first encrypted signal is the same as the number of elements included in each first perception signal), and the multiplication of the first perception signal and the first encrypted signal can be a frequency domain multiplication or conjugate multiplication of the first perception signal and the first encrypted signal corresponding to each same moment. Specifically, the following situations are included:

[0258] a) The first perception signal is phase-rotated only in the frequency domain by the first encrypted signal, and the distance / delay information can be encrypted at this time; for example, the perception signal sending node generates the first perception signal r(m) at the current moment, where m=0, 1, 2…, M-1 corresponds to the frequency domain sampling point or subcarrier number. The first perception signal is encrypted using a pseudo-random sequence (Pseudo-Noise, PN) sequence based on Quadrature Phase Shift Keying (QPSK) modulation to generate a first encrypted signal r1(m), where m=0, 1, 2…, M-1 corresponds to the frequency domain sampling point or subcarrier number. One way to generate the first encrypted signal is the same as the way to generate the first perception signal, using a PN sequence. However, the PN sequence generation initialization factor is determined and configured by the UE. When this encryption method is used, the encryption configuration information is the PN sequence generation initialization factor.

[0259] b) performing a phase rotation on the first sensing signal only in the time domain using the first encrypted signal, thereby encrypting the velocity / Doppler information;

[0260] c) Phase rotation is performed on the first sensing signal in the frequency domain and the time domain using the first encrypted signal, so that the distance / delay information and the speed / Doppler information can be encrypted.

[0261] Step 4: The network-side device (AMF) determines the perception configuration information based on the perception request message and other information, and sends the perception configuration information to the selected perception signal sending node and perception signal receiving node. When the UE is a perception signal receiving node and the perception signal is sent in an encrypted manner, the network-side device also needs to send at least one of a first encryption instruction and / or encryption configuration information for the perception signal to the UE. The first encryption instruction is used to instruct the perception signal sending node to encrypt the perception signal before sending it. The encryption configuration information for the perception signal includes PN sequence generation initialization factor information.

[0262] Step 5a: When the UE is a sensing signal receiving node, it receives the sensing signal according to the configuration information and performs sensing measurements. If the UE indicates that the sensing signal is to be sent in an encrypted manner, the UE decrypts the sensing measurement data based on the encryption configuration of the sent sensing signal to obtain the actual sensing measurement data.

[0263] Step 5b: When the UE is a perception signal sending node, the UE generates a perception signal and sends it. According to the privacy protection requirements, if the perception measurement can only be generated and processed in the UE, and the perception method is for non-UE to receive the perception signal, then the UE should encrypt the perception signal generated based on the network configuration (a potential encryption method is as described above, that is, the UE determines and generates a first encrypted signal, and multiplies it with the first perception signal (equivalent to performing a phase rotation on the first perception signal), etc.), and then sends the encrypted perception signal. Encryption can achieve the goal that the real perception measurement data cannot be obtained on non-UE devices. Then, the UE also needs to receive the perception measurement data sent by the non-UE perception signal receiving node or SF according to the network configuration information.

[0264] Step 6: The UE generates the required perception results based on the perception measurement data. Consider that the UE may need the network side device to assist in providing the perception data processing algorithm, or the UE may need the network side device to provide perception data auxiliary processing information. For example, gesture recognition may require AI model auxiliary processing, and the network side device may have a more suitable AI model recommendation based on historical data and experience; for example, when the base station serves as a perception signal receiving node, the UE needs base station location information to assist in the calculation of perception results. Optionally, the UE may send a perception data auxiliary processing request to the network side device, and then the UE may receive the perception data auxiliary processing information sent by the network side device. The perception data auxiliary processing information may include a perception algorithm indication (such as an AI model identifier), base station location information, etc.

[0265] Example 2: Perception request initiated by UE application function (AF)

[0266] This embodiment describes that the first device sending the perception request is a UE application function, which is usually processed by the UE application processor. The main differences from Example 1 are: the network function that receives the perception request message is different, and the process of selecting the perception node based on the UE IP address included in the perception request message sent by the UE application function. The specific process is described as follows:

[0267] Step 1: The UE application function sends a perception request message to the NEF, and the perception request message includes the first indication information. Optionally, the perception request message also includes the UE IP address. One implementation method is that the source address in the IP header of the perception request message indicates the UE IP address, or a certain information unit in the perception request message indicates the UE IP address. Optionally, the perception request message may also include at least one of the following: service type and service requirements. The service type is, for example, dynamic map, vehicle speed detection, vehicle tracking, emergency notification, and the service requirements include, for example, at least one of the following: perception resolution, perception accuracy, frame rate, duration, target area information, delay, perceived target information (such as vehicle type, vehicle identification, location information).

[0268] Optionally, the first indication information includes one of the following:

[0269] 1) indication information used to indicate whether the perception service requested by the first device requires privacy protection;

[0270] 2) the designated equipment;

[0271] Optionally, the designated device includes a UE that sends the perception request, or other devices associated with the perception request.

[0272] In an embodiment of the present application, optionally, the designated device includes at least one of a terminal, a base station, and a perception function.

[0273] In order for the first perception data to be generated or processed by the designated device, the designated device may be at least one of the following during the perception process:

[0274] A node that generates a perception result based on the perception measurement data;

[0275] Sensing signal receiving node;

[0276] Sensing signal sending node;

[0277] A node that provides perception assistance data.

[0278] 3) the designated device and sensing method;

[0279] In the embodiment of the present application, optionally, the sensing method includes at least one of the following:

[0280] The designated device autonomously sends and receives sensing signals;

[0281] The designated device sends a perception signal, and other devices other than the designated device receive the perception signal;

[0282] The designated device receives the perception signal, and other devices other than the designated device send the perception signal.

[0283] For example, the first indication information indicates that: the sensing signal receiving node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0284] Alternatively, the first indication information indicates that: the perception signal receiving node is a designated device and the perception mode is receiving the perception signal by the designated device and sending the perception signal to other devices other than the designated device;

[0285] Alternatively, the first indication information indicates that: the sensing signal sending node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0286] Alternatively, the first indication information indicates that: the perception signal sending node is a designated device and the perception mode is that the designated device sends the perception signal and other devices other than the designated device receive the perception signal.

[0287] 4) Type of the first perception data;

[0288] 5) a privacy protection level, where the privacy protection level indicates the type of the first perception data, and different privacy protection levels correspond to different types of first perception data;

[0289] 6) Indication information for indicating whether the perception signal needs to be sent encrypted;

[0290] 7) Encryption configuration information of the sensing signal;

[0291] 8) Instruction information for indicating whether the perception result needs to be sent encrypted;

[0292] 9) Configuration of encryption algorithm for perception results.

[0293] Note: The subsequent process is described using the example of the UE where the UE application function that sends the perception request is located as the designated device.

[0294] Step 2: NEF performs a perception authorization check on the perception request of the UE application function. After the perception authorization is passed, NEF selects an appropriate SF based on the target area information or the target object location information. One implementation method for NEF to perform a perception authorization check on the perception request of the UE application function is: the UE's perception authorization information can be stored in the NEF or UDM. If it is stored in the UDM, the NEF can request authorization verification from the UDM. NEF obtains the perception authorization information from the UDM and performs a perception authorization check. For example, if the UE does not allow a certain type of service or APP to obtain the perception measurement data or perception results related to the UE, the NEF rejects the perception request. From the perspective of the UE user, the perception measurement data or perception results include the environmental information around the UE, which is a relatively private type of data. If a certain type of service or APP wants to obtain the perception measurement data or perception results around the UE, the network-side device needs to first confirm whether the user of the UE allows the service or APP to obtain the above data.

[0295] Step 3: After the NEF passes the sensing authorization check, in one implementation, the NEF selects an appropriate AMF and sends a sensing request message to the AMF. The AMF then selects an appropriate SF. Specifically, the NEF queries the SMF for the UE ID (e.g., Subscription Permanent Identifier (SUPI)) within the mobile network based on the UE IP address information contained in the sensing request message. The NEF selects an appropriate AMF based on the AMF to which the UE is connected. The AMF then selects an appropriate SF based on the first indication information and sensing service type in the sensing request message. In another implementation, the NEF selects an appropriate SF and sends a sensing request message to the SF. Specifically, the NEF determines an appropriate SF based on the sensing request message (e.g., including the first indication information, sensing service type, sensing area, sensing target, etc.). The SF then queries the SMF for the UE ID (e.g., SUPI) within the mobile network based on the UE IP address information contained in the sensing request message. The SF obtains the AMF to which the UE is connected based on the UE ID and sends the UE ID to the AMF to query the UE's serving cell and its neighboring cells.

[0296] Step 4: The SF determines the sensing mode and sensing node based on the first indication information. If the first indication information specifies a device or sensing mode, and the SF cannot configure the specified device or sensing mode, the SF may send a message rejecting the sensing request. Optionally, the rejection message carries a rejection reason, which includes the failure to meet the requirements of the first indication information. If the SF continues to perform sensing, the SF shall determine the sensing mode and sensing node based on the first indication information, for example:

[0297] If the first indication information in the perception request message indicates that the UE where the UE application function sending the perception request message is located is a perception signal sending node, then the SF first determines that the UE is a perception signal sending node, and then determines the perception method, and determines whether it is necessary to determine a device other than the UE sending the perception request message as a perception signal receiving node based on the perception method.

[0298] If the first indication information in the perception request message indicates that the UE where the UE application function sending the perception request message is located is a perception signal receiving node, then the SF first determines that the UE is a perception signal receiving node, then determines the perception method, and determines whether it is necessary to determine a device other than the UE sending the perception request as a perception signal sending node based on the perception method.

[0299] If the first indication information in the perception request message indicates that the UE where the UE application function sending the perception request message is located is a perception signal sending node or a perception signal receiving node, when the perception mode is a perception mode of sending and receiving perception signals between the UE and other devices, the SF should select a device other than the UE as a perception signal receiving node or a perception signal sending node according to the corresponding perception mode; when the perception mode is that the UE sends and receives the perception signal itself, the SF does not need to determine the perception signal sending node and the perception signal receiving node.

[0300] Optionally, when the first indication information includes that the perception signal receiving node is a designated device, the UE may further indicate, through the first indication information, whether the perception signal is sent in an encrypted manner. If the perception signal is sent in an encrypted manner, the first indication information may further include encryption configuration information for the perception signal. The encryption configuration information for the perception signal may be carried by the aforementioned perception request message or by other messages.

[0301] An example of a perception signal encryption method is when the required perception result includes at least one of range / delay and speed / Doppler. The perception signal encryption method may be: after the perception signal transmitting node generates a first perception signal based on the configuration information of the traditional perception signal, it encrypts the first perception signal to generate a first encrypted signal, and multiplies the first encrypted signal by the first perception signal (equivalent to performing a phase rotation on the first perception signal) to obtain a first target perception signal. The generation method of the first encrypted signal is determined by the UE.

[0302] The first perception signal at each moment corresponds to a first encrypted signal, each first encrypted signal includes m elements (the number of elements included in each first encrypted signal is the same as the number of elements included in each first perception signal), and the multiplication of the first perception signal and the first encrypted signal can be a frequency domain multiplication or conjugate multiplication of the first perception signal and the first encrypted signal corresponding to each same moment. Specifically, the following situations are included:

[0303] a) The first perception signal is phase-rotated only in the frequency domain by the first encrypted signal, and the distance / delay information can be encrypted at this time; for example, the perception signal sending node generates the first perception signal r(m) at the current moment, where m=0, 1, 2…, M-1 corresponds to the frequency domain sampling point or subcarrier number. The first perception signal is encrypted using a pseudo-random sequence (Pseudo-Noise, PN) sequence based on Quadrature Phase Shift Keying (QPSK) modulation to generate a first encrypted signal r1(m), where m=0, 1, 2…, M-1 corresponds to the frequency domain sampling point or subcarrier number. One way to generate the first encrypted signal is the same as the way to generate the first perception signal, using a PN sequence. However, the PN sequence generation initialization factor is determined and configured by the UE. When this encryption method is used, the encryption configuration information is the PN sequence generation initialization factor.

[0304] b) performing a phase rotation on the first sensing signal only in the time domain using the first encrypted signal, thereby encrypting the velocity / Doppler information;

[0305] c) Phase rotation is performed on the first sensing signal in the frequency domain and the time domain using the first encrypted signal, so that the distance / delay information and the speed / Doppler information can be encrypted.

[0306] Step 5: The network-side device determines the perception configuration information based on the perception request message and other information, and sends the perception configuration information to the selected perception signal sending node and the perception signal receiving node. When the UE is a perception signal receiving node and the perception signal is sent in an encrypted manner, the network-side device also needs to send at least one of a first encryption instruction and / or encryption configuration information of the perception signal to the UE. The first encryption instruction is used to instruct the perception signal sending node to encrypt the perception signal before sending it. The encryption configuration information of the perception signal includes PN sequence generation initialization factor information.

[0307] Step 6a: When the UE is a sensing signal receiving node, it receives the sensing signal according to the configuration information and performs sensing measurements. If the UE indicates that the sensing signal is to be sent in an encrypted manner, the UE decrypts the sensing measurement data based on the encryption configuration of the sent sensing signal to obtain the actual sensing measurement data.

[0308] Step 6b: When the UE is a perception signal sending node, the UE generates a perception signal and sends it. According to the privacy protection requirements, if the perception measurement can only be generated and processed in the UE, and the perception method is for non-UE to receive the perception signal, then the UE should encrypt the perception signal generated based on the network configuration (a potential encryption method is as described above, that is, the UE determines and generates a first encrypted signal, and multiplies it with the first perception signal (equivalent to performing a phase rotation on the first perception signal), etc.), and then sends the encrypted perception signal. Encryption can ensure that the real perception measurement data cannot be obtained on non-UE devices. Then, the UE also needs to receive the perception measurement data sent by the non-UE perception signal receiving node or SF according to the network configuration information.

[0309] Step 7: The UE generates the required perception results based on the perception measurement data. Consider that the UE may need the network side device to assist in providing the perception data processing algorithm, or the UE may need the network side device to provide perception data auxiliary processing information. For example, gesture recognition may require AI model auxiliary processing, and the network side device may have a more suitable AI model recommendation based on historical data and experience; for example, when the base station serves as a perception signal receiving node, the UE needs base station location information to assist in the calculation of perception results. Optionally, the UE may send a perception data auxiliary processing request to the network side device, and then the UE may receive the perception data auxiliary processing information sent by the network side device. The perception data auxiliary processing information may include a perception algorithm indication (such as an AI model identifier), base station location information, etc.

[0310] Example 3: Perception request initiated by an application function not deployed on the UE

[0311] This embodiment describes that the first device that sends the perception request is an application function. The difference from embodiment 2 is that the application function is an OTT (Over The Top) application server, etc., rather than an application function deployed on the UE. The specific process is described as follows:

[0312] Step 1: Optionally, the UE reports its sensing capabilities, which include the ability of the first device to generate sensing results based on sensing measurement data. Since the ability of the first device to generate sensing results based on sensing measurement data is typically closely related to the storage and computing capabilities of the first device, this capability can be represented by reporting the sensing capabilities. The sensing results can be related to the user's vital signs or private areas. Optionally, the sensing results can include at least one of the following: respiratory rate, intrusion detection, gesture recognition, and motion monitoring.

[0313] Step 2: Optionally, the UE sends perception authorization information to the network side device. The perception authorization information includes at least one of the following: an identifier of the application function that is allowed to request the perception service (such as the APP name or IP address port number, etc.), the type of perception service that the application function is allowed to request, and the type of perception data that the application function is allowed to request. The application function includes at least one of the UE application function and the network side application function. Optionally, the information contained in the perception authorization information is related to the user's vital signs or private areas. For example, health monitoring APP 1 is allowed to request perception results / perception service type 1 (such as respiratory monitoring) in area A (such as a private room).

[0314] Step 3: The application function sends a perception request message to the NEF, and the perception request message includes first indication information. Optionally, the first indication information may include a list of specified device identifiers (such as mobile phone numbers, IP addresses, etc.). Optionally, the first indication information may also include: indication information for indicating whether the perception signal needs to be sent encrypted and / or encryption configuration information of the perception signal. Optionally, the first indication information may also include: indication information for indicating whether the perception result needs to be sent encrypted and / or encryption algorithm configuration of the perception result. Optionally, the perception request message may also include at least one of the following: service type and service requirements. The service type is, for example, dynamic map, vehicle speed detection, vehicle tracking, emergency notification, and the service requirements include, for example, at least one of the following: perception resolution, perception accuracy, frame rate, duration, target area information, latency, perceived target information (such as vehicle type, vehicle identification, location information).

[0315] Optionally, the first indication information includes one of the following:

[0316] 1) indication information used to indicate whether the perception service requested by the first device requires privacy protection;

[0317] 2) the designated equipment;

[0318] Optionally, the designated device includes a UE that sends the perception request, or other devices associated with the perception request.

[0319] In an embodiment of the present application, optionally, the designated device includes at least one of a terminal, a base station, and a perception function.

[0320] In order for the first perception data to be generated or processed by the designated device, the designated device may be at least one of the following during the perception process:

[0321] A node that generates a perception result based on the perception measurement data;

[0322] Sensing signal receiving node;

[0323] Sensing signal sending node;

[0324] A node that provides perception assistance data.

[0325] 3) the designated device and sensing method;

[0326] In the embodiment of the present application, optionally, the sensing method includes at least one of the following:

[0327] The designated device autonomously sends and receives sensing signals;

[0328] The designated device sends a perception signal, and other devices other than the designated device receive the perception signal;

[0329] The designated device receives the perception signal, and other devices other than the designated device send the perception signal.

[0330] For example, the first indication information indicates that: the sensing signal receiving node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0331] Alternatively, the first indication information indicates that: the perception signal receiving node is a designated device and the perception mode is receiving the perception signal by the designated device and sending the perception signal to other devices other than the designated device;

[0332] Alternatively, the first indication information indicates that: the sensing signal sending node is a designated device and the sensing mode is autonomous transmission and reception by the designated device;

[0333] Alternatively, the first indication information indicates that: the perception signal sending node is a designated device and the perception mode is that the designated device sends the perception signal and other devices other than the designated device receive the perception signal.

[0334] 4) Type of the first perception data;

[0335] 5) a privacy protection level, where the privacy protection level indicates the type of the first perception data, and different privacy protection levels correspond to different types of first perception data;

[0336] 6) Indication information for indicating whether the perception signal needs to be sent encrypted;

[0337] 7) Encryption configuration information of the sensing signal;

[0338] 8) Instruction information for indicating whether the perception result needs to be sent encrypted;

[0339] 9) Configuration of encryption algorithm for perception results.

[0340] Step 4: NEF performs a perception authorization check on the perception request of the application function. After the perception authorization is passed, NEF selects an appropriate SF based on the target area information or the target object location information. One implementation method for NEF to perform a perception authorization check on the perception request of the application function is: the UE's perception authorization information can be stored in the NEF or UDM. If it is stored in the UDM, the NEF can request authorization verification from the UDM. NEF obtains the perception authorization information from the UDM and performs a perception authorization check. For example, if the UE does not allow a certain type of service or APP to obtain the perception measurement data or perception results related to the UE, the NEF rejects the perception request. From the perspective of the UE user, the perception measurement data or perception results include the environmental information around the UE, which is a relatively private type of data. If a certain type of service or APP wants to obtain the perception measurement data or perception results around the UE, the network-side device needs to first confirm whether the user of the UE allows the service or APP to obtain the above data.

[0341] Step 5: After the NEF passes the sensing authorization check, in one implementation, the NEF selects an appropriate AMF and sends a sensing request message to the AMF. The AMF then selects an appropriate SF. Specifically, the NEF queries the SMF for the UE ID (e.g., Subscription Permanent Identifier (SUPI)) within the mobile network based on the UE IP address information contained in the sensing request message. The NEF selects an appropriate AMF based on the AMF to which the UE is connected. The AMF then selects an appropriate SF based on the first indication information and sensing service type in the sensing request message. In another implementation, the NEF selects an appropriate SF and sends a sensing request message to the SF. Specifically, the NEF determines an appropriate SF based on the sensing request message (e.g., including the first indication information, sensing service type, sensing area, sensing target, etc.). The SF then queries the SMF for the UE ID (e.g., SUPI) within the mobile network based on the UE IP address information contained in the sensing request message. The SF obtains the AMF to which the UE is connected based on the UE ID and sends the UE ID to the AMF to query the UE's serving cell and its neighboring cells.

[0342] Step 6: SF determines the perception mode and perception node based on the first indication information. When the first indication information has specified the device or perception mode, SF needs to perform a perception authorization check on the specified device. One method based on the 5G protocol is for SF to obtain the perception authorization information from UDM and perform a perception authorization check. For example, if the UE in the designated device identification list included in the perception request message does not allow the APP to request or does not allow the APP to request a certain perception service, the SF rejects the perception request. The reason for rejection is that the designated device authorization has not been obtained. If perception is to be continued, the SF should determine the perception mode and perception node according to the first indication information, for example:

[0343] If the first indication information in the perception request indicates that the perception service requested by the first device requires privacy protection, but does not indicate the perception signal sending node, perception signal receiving node, perception mode, etc., the SF may determine the perception signal sending node, perception signal receiving node, perception mode, etc. based on the designated device identifier list, perception authorization information, etc.

[0344] If the first indication information in the perception request indicates that the designated device A is the perception signal sending node, then the SF first determines that device A is the perception signal sending node, then determines the perception method, and based on the perception method, whether it is necessary to determine a device other than device A as a perception signal receiving node.

[0345] If the first indication information in the perception request indicates that the designated device A is the perception signal receiving node, then the SF first determines device A as the perception signal receiving node, then determines the perception method, and determines a device other than device A as the perception signal sending node based on the perception method.

[0346] If the first indication information in the perception request indicates that the designated device A is the perception signal sending node or the perception signal receiving node, when the perception mode is the perception signal transmission and reception between device A and other devices, SF should select a device other than device A as the perception signal receiving node or the perception signal sending node according to the corresponding perception mode; when the perception mode is that device A transmits and receives independently, then SF does not need to determine the perception signal sending node and the perception signal receiving node.

[0347] If the first indication information in the perception request indicates that the designated device A and the designated device B are the perception signal sending node and the perception signal receiving node, then the SF does not need to determine the perception signal sending node and the perception signal receiving node.

[0348] Step 7: The network device determines the sensing configuration information based on the sensing request message and other information, and sends the sensing configuration information to the selected sensing signal sending node and sensing signal receiving node. If the sensing request message indicates that the sensing signal needs to be sent encrypted, the network device also sends at least one of a first encryption instruction and / or sensing signal encryption configuration information to the sensing signal sending node. The first encryption instruction instructs the sensing signal sending node to encrypt the sensing signal before sending it. The sensing signal encryption configuration information includes information about a PN sequence generation initialization factor. Simultaneously, the network device also sends the sensing signal encryption configuration information to the sensing signal receiving node. If the application function that sent the sensing request message requires a sensing result, the network device sends sensing result transmission configuration information to the designated device that generated the sensing result. The sensing result transmission configuration information includes an application function identifier (e.g., an app name or an IP address or port number). Optionally, if the sensing request message indicates that the sensing result needs to be sent encrypted, the network device also sends an encryption instruction for encrypting the sensing result and / or a sensing result encryption algorithm configuration to the designated device that generated the sensing result. Examples of the encryption algorithm include AES, SNOW 3G, and ZUC. In order to prevent the perception results from being parsed when transmitted via the 3GPP network, key information used in various encryption algorithms is configured by the application function.

[0349] Step 8a: When designated device A is the sensing signal receiving node, the UE receives the sensing signal according to the configuration information and performs sensing measurements. If the sensing signal is sent in an encrypted manner, designated device A decrypts the sensing measurement data based on the received encryption configuration to obtain the true sensing measurement data.

[0350] Step 8b: When the designated device A is the sensing signal sending node, the designated device A generates and sends the sensing signal according to the configuration information.

[0351] Step 9: The designated device (which may be designated device A or other designated device) obtains the perception measurement data and generates the required perception results based on the perception measurement data. Consider that the designated device may need the network side device to assist in providing the perception data processing algorithm, or the designated device may need the network side device to provide perception data auxiliary processing information. For example, gesture recognition may require AI model auxiliary processing, and the network side device may have a more suitable AI model recommendation based on historical data and experience; for example, when the base station serves as a perception signal receiving node, the designated device needs base station location information to assist in the calculation of perception results. Optionally, the designated device may send a perception data auxiliary processing request to the network side device, and then the designated device may receive the perception data auxiliary processing information sent by the network side device. The perception data auxiliary processing information may include a perception algorithm indication (such as an AI model identifier), base station location information, etc.

[0352] Step 10: The designated device (which may be designated device A or another designated device) sends the generated sensing result to the application function. It should be noted that the data sent in this step is user data and is therefore transparent to the 3GPP network function.

[0353] Example 4: A perception method based on privacy protection level indication

[0354] This embodiment describes how to indicate privacy protection through the definition of privacy protection levels. The specific process is as follows:

[0355] Step 1: The first device (UE or application server) sends a perception request message to the network side device (such as AMF), and the perception request message includes first indication information. Optionally, the perception request message may also include at least one of the following: service type and service requirements. The service type may be, for example, dynamic map, vehicle speed detection, vehicle tracking, and emergency notification. The service requirements may include, for example, at least one of the following: perception resolution, perception accuracy, frame rate, duration, target area information, latency, and perceived target information (such as vehicle type, vehicle identification, and location information).

[0356] The first indication information includes a privacy protection level, where the privacy protection level is used to indicate a type of the first perception data. Different privacy protection levels correspond to different types of first perception data.

[0357] An example of a privacy protection level definition is shown below. The numbers in the example are for illustrative purposes only and are not intended to be limiting:

[0358] The first privacy protection level (also referred to as level 1 or first level, etc., is only used to illustrate the number and the name is not limited to this). The first privacy protection level is used to indicate that the perception result is generated or processed by a specified device; that is, the perception result is generated or processed on the specified device, that is, the required perception result based on the perception measurement data is completed on the specified device.

[0359] The second privacy protection level (also referred to as level 2 or level 2, etc.) indicates that the perception assistance data and perception results are generated or processed by a designated device. Perception results are typically generated in conjunction with the location of the UE sending or receiving the perception signal, or perception assistance data such as an environmental map. While the first privacy protection level may allow other devices that obtain the perception assistance data to calculate the corresponding perception results, the second privacy protection level excludes the perception assistance data from the designated device. This further reduces the probability of non-designated devices obtaining the perception results when perception results based on the perception assistance data are required.

[0360] The third privacy protection level (also referred to as level 3 or level 3) indicates that the perception measurement data and perception results are generated or processed by a designated device. This means that the perception measurement data is generated or processed on the designated device. When non-designated devices cannot obtain the perception measurement data, the probability of non-designated devices obtaining the perception results and related information is further reduced compared to the first privacy protection level.

[0361] The fourth privacy protection level (also referred to as level 4 or fourth level, etc.) is used to indicate that the perception assistance data, perception measurement data and perception results are generated or processed by a designated device; this means that the perception assistance data, perception measurement data and perception results are all generated or processed on the designated device.

[0362] The fifth privacy protection level (also referred to as level 5 or level 5, etc.) indicates that the perception-assisted data, perception-measurement data, and perception results are generated or processed by a designated device, and that the perception mode is that the designated device autonomously transmits and receives perception signals. This autonomous transmission and reception of perception signals by designated devices helps avoid the risk of leakage of perception-assisted data, perception-measurement data, or perception results due to leakage of perception information by non-designated devices when transmitting or receiving between non-designated devices and designated devices.

[0363] In an embodiment of the present application, optionally, the perception measurement data includes at least one of the following: real perception measurement data and encrypted perception measurement data, and the third privacy protection level includes at least one of the following:

[0364] The first sub-level (also known as level 3-1, etc.) indicates that the actual perception measurement data and results are generated or processed by a designated device. One implementation involves designating the designated device as a perception signal receiving node, so that the perception measurement data is generated and processed by the designated device and not transmitted to other devices. Alternatively, the designated device is a perception signal receiving node, and the perception signal transmitting node is configured to send the perception signal in an encrypted manner, thereby preventing other nodes that can receive the signal from obtaining the actual perception measurement data.

[0365] The second sublevel (also known as level 3-2, etc.) indicates that real perception measurement data, encrypted perception measurement data, and perception results are generated or processed by designated devices. In one implementation, the designated device is the sensing signal sending node, and the sensing signal is sent in an encrypted manner, so that only the designated device can obtain the real perception measurement data.

[0366] In this embodiment of the present application, optionally, the perception measurement data includes first perception measurement data (also referred to as a first perception measurement quantity) and second perception measurement data (also referred to as a second perception measurement quantity), the perception result includes a first perception result (also referred to as a third perception measurement quantity) and a second perception result (also referred to as a fourth perception measurement quantity), and the third privacy protection level includes at least one of the following:

[0367] a third sublevel (or referred to as level 3-1, etc.), the third sublevel being used to indicate that the first perception measurement data, the first perception result, and the second perception result are generated or processed by a designated device;

[0368] a fourth sublevel (or referred to as level 3-2, etc.), the fourth sublevel being used to indicate that the first perception measurement data, the second perception measurement data, the first perception result, and the second perception result are generated or processed by a designated device;

[0369] a fifth sublevel (or referred to as level 3-3, etc.), the fifth sublevel being used to indicate that the first perception measurement data and the first perception result are generated or processed by a designated device;

[0380] Step 2: Optionally, the network-side device selects a suitable SF and performs a perception privacy check, wherein the perception privacy check at least includes whether the designated device allows the first device to request the perception result.

[0381] Step 3: The network side device determines the sensing mode and sensing node according to the first indication information and sends the sensing configuration information. The sensing node generates and processes the sensing data according to the configuration information. The specific implementation method is detailed in the corresponding steps of Examples 1 to 3 and will not be repeated here.

[0382] The functions performed by the network side device in the above embodiment (such as the functions performed by any one of AMF, NEF, SF, etc. or the superposition of any multiple functions performed) correspond to the functions performed by the above second device.

[0383] The following describes the perception configuration information involved in the above embodiments.

[0384] The perception configuration information includes at least one of perception measurement object configuration information / perception signal configuration information, perception measurement quantity configuration, perception report configuration, and perception data transmission configuration.

[0385] Wireless sensing is achieved by measuring received signals and then processing the measurement results to obtain the desired sensing results. Therefore, the configuration of the sensing signal can also be called the configuration of the sensing measurement object, which includes at least one of the following:

[0386] 1) Waveforms, such as 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;

[0387] 2) Subcarrier spacing: For example, the subcarrier spacing of the OFDM system is 30KHz;

[0388] 3) Guard interval: The time interval between the moment a signal ends and the moment its latest echo signal is received. This parameter is proportional to the maximum sensing distance. For example, it can be calculated as 2dmax / c, where dmax is the maximum sensing distance (a sensing requirement). For example, for a self-transmitting and self-receiving sensing signal, dmax represents the maximum distance between the sensing signal receiving and transmitting point. In some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval. c is the speed of light.

[0389] 4) Bandwidth: 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 (a perception requirement);

[0390] 5) Burst duration: This parameter is inversely proportional to the rate resolution (a perception requirement). It is the time span of the perceived signal and is primarily used to calculate Doppler frequency offset. This parameter can be calculated as c / 2 / delta_v / fc, where delta_v is the rate resolution and fc is the carrier frequency or the center frequency of the signal.

[0391] 6) Time interval: This parameter can be calculated as c / 2 / fc / v_range; where v_range is the maximum rate minus the minimum rate (which belongs to the sensing requirement); this parameter is the time interval between two adjacent sensing signals;

[0392] 7) Sense the transmit power of the signal, for example, taking a value every 2dBm from -20dBm to 23dBm;

[0393] 8) Information about the sending port of the sensing signal, including quantity and port number;

[0394] 9) Signal formats, such as Channel State Information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), Positioning Reference Signals (PRS), or other predefined signals, as well as related sequence format information;

[0395] 10) Signal direction; for example, the direction of the perceived signal (e.g., base station transmits and UE receives, base station receives and UE transmits, base station transmits and receives, base station transmits and receives, UE transmits and receives, UE transmits and receives, UE transmits and receives, and UE transmits and receives)

[0396] 11) Sense the beam information of the signal;

[0397] 12) Time resources, such as the time slot index or symbol index of the time slot where the perception signal is located; there are two types of time resources: one is a one-time time resource, for example, one symbol sends an omnidirectional first signal; the other is a non-one-time time resource, such as multiple groups of periodic time resources or discontinuous time resources (which may include start time and end time). Each group of periodic time resources sends a perception signal in the same direction, and different groups of periodic time resources have different beam directions.

[0398] 13) Frequency resources, including the center frequency, bandwidth, resource block (RB) or subcarrier of the perception signal. When the first node transmits information about the second node, the center frequency is the center frequency of the second node. If the second node supports multiple cells, the center frequency list includes the center frequencies corresponding to the multiple cells. For sidelink communication methods like New Radio (NR), the perception measurement object is a set of transmission resource pools used for NR sidelink communication on a single carrier frequency.

[0399] 14) Quasi Co-Location (QCL) relationship, for example, the sensing signal includes multiple resources, each resource is associated with a synchronization signal block (Synchronization Signal and PBCH block, SSB) QCL, and QCL includes Type A, B, C or D.

[0400] The sensing measurement parameters configuration is used to instruct the sensing measurement node to measure at least one of the following sensing measurement parameters:

[0401] 1) First-level measurement quantity (also called received signal / original channel information), including at least one of the following: received signal / channel response complex result, amplitude / phase, I-path / Q-path and operation results thereof (operations include at least one of the following: addition, subtraction, multiplication, division, matrix addition, subtraction, multiplication, matrix transposition, trigonometric relationship operation, square root operation, and power operation, as well as threshold detection results, maximum / minimum value extraction results, etc. of the above operation results; optionally, the operation also includes at least one of the following: Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT) / Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform and digital filtering, as well as threshold detection results, maximum / minimum value extraction results, etc. of the above operation results);

[0402] 2) Second-level measurement quantities (also called basic measurement quantities), including at least one of the following: delay, Doppler, angle, signal strength, and their multi-dimensional combination representations;

[0403] 3) Level 3 measurements (also known as perception results) include at least one of the following: target presence, distance, speed, angle / direction, RCS, acceleration, position, trajectory, movement, expression, breathing rate, heart rate, imaging results, weather, air quality, material and composition, etc.

[0404] The perception measurement report configuration includes at least one of the following:

[0405] 1) The access type used for report transmission is indicated, which can be 3GPP access or non-3GPP access. Further, 3GPP access can be indicated as 4G (LTE), 5G (NR), 6G, etc., and non-3GPP can be indicated as wireless local area networks (WLAN), Bluetooth, and wired networks, etc. If there are multiple, the priority order can also be reflected through a list. For example, if the access type used for report transmission is indicated as 5G or 4G, it means that 5G is used to transmit the report first.

[0406] 2) Reporting criteria: The criteria that triggers the sensing measurement node to send measurement reports can be periodic, event-triggered, or indicated. Events include but are not limited to the following:

[0407] 2a) The perceived signal quality detected by the receiving end meets the threshold requirements, such as at least one of the following: the signal-to-noise ratio (SNR), the reference signal received power (RSRP), the received signal strength indication (RSSI), and the signal-to-clutter ratio threshold. If the threshold is met, the perceived measurement quantity in the perception measurement item configuration is measured and reported.

[0408] 2b) The perception measurement results obtained by the receiving end do not meet the perception requirements, that is, the perception performance indicator corresponding to the calculated perception measurement results meets or exceeds a preset threshold, such as the perception SNR (a potential definition is the ratio of the effective signal power of the signal propagation path corresponding to the perception target to the noise power, or the ratio of the effective signal power of the signal propagation path corresponding to the perception target to the sum of the noise power and the signal power of the signal propagation paths corresponding to non-perception targets);

[0409] 2c) The receiving end correctly demodulates the data (e.g., passes a cyclic redundancy check (CRC) check) and performs perception based on the communication data, using a demodulation-first, then perception parameter estimation approach. If the communication demodulation is incorrect, the perception measurement results will be affected and become unreliable.

[0410] 2d) Mandatory perception measurements meet requirements. For example, the latency, Doppler, and Global Positioning System (GPS) location information for the perception signal are mandatory perception measurements, while RSRP and Reference Signal Received Quality (RSRQ) are optional. Therefore, they are reported only when multiple mandatory perception measurements are available.

[0411] 3) Report format: The report includes the maximum number of cells under the radio access technology (Radio Access Technology, RAT) supported by the second node, the maximum number of measurement quantities for each cell, etc.
