[0038] The following briefly describes the technical content related to this application.

[0039] 1. Communication perception integration / sensing and communication integration:

[0040] Future Beyond 5G (B5G) and 6th generation mobile networks (6G) wireless communication systems are expected to provide various high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing in smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are usually designed separately and occupy different frequency bands. Integrated Sensing And Communication (ISAC) enables the sharing of the same frequency band and hardware between sensing and communication systems, improves frequency efficiency, and reduces hardware costs. ISAC will become a key technology for future wireless communication systems to support many important application scenarios. Typical applications of ISAC include: navigation and obstacle avoidance for autonomous vehicles, Wi-Fi-based indoor positioning and activity recognition, communication and sensing for unmanned aerial vehicles, Extended Reality (XR), integration of radar and communication, etc. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted great research interest and attention in both academia and industry.

[0041] ISAC achieves an integrated low-cost implementation of dual functions of communication and sensing through the sharing of hardware devices and software-defined functions. Its main characteristics are: first, the architecture is unified and simplified; second, the functions are reconfigurable and extensible; third, the efficiency is improved and the cost is reduced. The advantages of integrated communication and sensing mainly include three aspects: first, the device cost is reduced and the size is decreased; second, the spectrum utilization rate is improved; third, the system performance is improved.

[0042] Currently, typical scenarios of integrated communication and sensing that are expected to be achieved through technological upgrades based on the 5G communication system architecture are shown in Table 1.

[0043] Table 1 Typical Scenarios of Integrated Communication and Sensing

[0044]

[0045] According to the different sending and receiving nodes of the sensing signal, it is divided into 6 basic sensing methods, as Figure 2 shown, specifically including:

[0046] (1) Base station self-transmitting and self-receiving sensing: In this sensing method, base station A sends a sensing signal and performs sensing measurements by receiving the echo of this sensing signal.

[0047] (2) Air interface sensing between base stations: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0048] (3) Uplink air interface sensing: Base station A receives the sensing signal sent by terminal A and performs sensing measurements.

[0049] (4) Downlink air perception: The terminal B receives the perception signal sent by the base station B and performs perception measurement.

[0050] (5) Terminal self-transmission and self-reception perception: The terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0051] (6) Inter-terminal sidelink perception: The terminal B receives the perception signal sent by the terminal A and performs perception measurement.

[0052] It should be noted that Figure 2 each perception method in takes a perception signal sending node and a perception signal receiving node as examples. In an actual system, one or more different perception methods can be selected according to different perception use cases and perception requirements, and there can be one or more perception signal sending nodes and perception signal receiving nodes for each perception method. Figure 2 The perception targets in take people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal transceiver devices. The perception targets in the actual scenario will be more diverse.

[0053] 2. Feasibility study on communication and sensing integration

[0054] 3GPP TR 22.837 elaborates on 32 perception use cases for communication and sensing integration.

[0055] At the same time, 22.837 also clearly puts forward considerations for privacy in the consideration section of Chapter 6.

[0124] In an embodiment of the present application, optionally, the sensing method further includes: the first device reports its sensing capabilities, where the sensing capabilities include the ability of the first device to generate sensing results based on sensing measurement data, such that the second device can determine, based on the sensing capabilities of the first device, that the first device is a specified device for generating sensing results based on sensing measurement data. Since the ability of the first device to generate sensing results based on sensing measurement data is usually closely related to the storage and computing capabilities of the first device, it can be characterized by reporting the sensing capabilities. The sensing results may be sensing results related to the user's vital signs or the user's private area. Optionally, the sensing results may include at least one of the following: respiratory rate, intrusion detection, gesture recognition, and motion monitoring, etc.

[0125] In an embodiment of the present application, optionally, the first device is a node for generating sensing results based on sensing measurement data, and the sensing method further includes: the first device receives sensing data auxiliary processing information, which is used to assist the first device in generating sensing results.

[0126] Optionally, before the first device receives the sensing data auxiliary processing information, it further includes: the first device sends a sensing data auxiliary processing request, which is used to request the sensing data auxiliary processing information.

[0127] Optionally, the sensing data auxiliary processing information includes at least one of the following: sensing algorithm indication (such as AI model identification), base station location information, etc.

[0128] In an embodiment of the present application, optionally, the sensing method further includes: the first device reports sensing authorization information, where the sensing authorization information includes at least one of the following: the identifier of the application function that is allowed to request the sensing service (such as APP name or IP address port number, etc.), the type of sensing service allowed to be requested by the application function, and the type of sensing data allowed to be requested by the application function. The application function includes at least one of the UE application function and the application function on the network side. Optionally, the information included in the sensing authorization information is related to the user's vital signs or private area. For example, allowing the health monitoring APP 1 to request sensing results / sensing service type 1 (such as respiratory monitoring) within area A (such as a certain private room).

[0129] In an embodiment of the present application, optionally, the first device is a sensing signal sending node, and the sensing method of this embodiment of the present application further includes the following steps:

[0130] The first device generates a first sensing signal;

[0131] The first device encrypts the first sensing signal to generate a first target sensing signal;

[0132] The first device sends the first target sensing signal;

[0133] The first device receives encrypted sensing measurement data based on the first target sensing signal;

[0134] The first device decrypts the encrypted sensing measurement data to obtain the true sensing measurement data.

[0135] An example of the encryption method for the sensing signal is when the required sensing result includes at least one of distance / delay, speed / Doppler. The encryption method of the sensing signal can be: after the sensing signal sending node generates the first sensing signal according to the configuration information of the traditional sensing signal, encrypts the first sensing signal to generate the first encrypted signal, and multiplies the first encrypted signal by the first sensing signal (equivalent to performing phase rotation on the first sensing signal) to obtain the first target sensing signal, and the generation method of the first encrypted signal is determined by the UE.

[0136] The first sensing signal at each moment corresponds to a first encrypted signal, and each first encrypted signal contains m elements (the number of elements contained in each first encrypted signal is the same as the number of elements contained in each first sensing signal). The multiplication of the first sensing signal and the first encrypted signal can be the multiplication or conjugate multiplication of the first sensing signal and the first encrypted signal corresponding to the same moment in the frequency domain. Specifically, it includes the following situations:

[0137] a) Phase-rotate the first sensing signal only in the frequency domain through the first encrypted signal, and at this time, the distance / delay information can be encrypted; for example, the sensing signal sending node generates the first sensing signal r(m) at the current moment, where m = 0, 1, 2…, M - 1 corresponds to the frequency domain sampling points or subcarrier numbers. Among them, the first sensing signal is encrypted using a pseudo-random sequence (PN) sequence based on quadrature phase shift keying (QPSK) modulation to generate the first encrypted signal r1(m), where m = 0, 1, 2…, M - 1 corresponds to the frequency domain sampling points or subcarrier numbers. One generation method of the first encrypted signal is the same as the generation method of the first sensing signal, using a PN sequence. However, the initialization factor for generating the PN sequence is determined and configured by the UE. When using this encryption method, the encryption configuration information is the initialization factor for generating the PN sequence.

[0138] b) Phase-rotate the first sensing signal only in the time domain through the first encrypted signal, and at this time, the speed / Doppler information can be encrypted;

[0142] The first device receives the encrypted sensing signal, and decrypts and performs sensing measurement on the encrypted sensing signal according to at least one of the first encryption indication information and the encryption configuration information of the sensing signal to obtain real sensing measurement data.

[0143] In some other embodiments of the present application, the first encryption indication information may also be used to indicate whether the sensing signal is sent through an encryption method.

[0147] The first device encrypts the first sensing result to generate a third encryption signal;

[0148] The first device sends the third encryption signal.

[0149] In an embodiment of the present application, if the first device performs sensing measurement and sensing result processing, the delay for the first device (such as a vehicle or a UE with communication function when the unmanned aerial vehicle (UAV) is a UE) to obtain the sensing result can also be shortened, meeting high-real-time sensing scenarios such as vehicle autonomous driving or UAV collision avoidance.

For the first privacy protection level, other devices that obtain the sensing auxiliary data may also calculate the corresponding sensing results. However, in the second privacy protection level, the sensing auxiliary data does not leave the specified device, which further reduces the probability of non-specified devices obtaining the sensing results in cases where sensing results need to be generated based on the sensing auxiliary data.

[0190] The third privacy protection level (which may also be referred to as level 3 or the third level, etc.), and the third privacy protection level is used to indicate that the sensing measurement data and sensing results are generated or processed by a specified device; this means that the sensing measurement data is generated or processed on the specified device.

[0219] Next, in combination with a specific application scenario, an example of the sensing method of the present application will be described.

[0220] Embodiment 1: Sensing request initiated by a UE modem

[0221] In this embodiment, it is described that the first device sending the sensing request is a UE modem (hereinafter simply referred to as UE), and the specific process is described as follows:

[0222] Step 1: The UE sends a sensing request message to a network-side device (such as an AMF), and the sensing request message includes first indication information. Optionally, the sensing request message may further 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 event notification, and the service requirements include, for example, at least one of the following: sensing resolution, sensing accuracy, frame rate, duration, target area information, time delay, and sensed target information (such as vehicle type, vehicle identifier, location information).

[0223] Optionally, the first indication information includes one of the following:

[0224] 1) Indication information used to indicate whether the sensing service requested by the first device requires privacy protection;

[0225] 2) The specified device;

[0226] Optionally, the specified device includes the UE that sends the sensing request, or other devices associated with the sensing request.

[0227] In an embodiment of the present application, optionally, the specified device includes at least one of a terminal, a base station, and a sensing function.

[0228] In order for the first sensing data to be generated or processed by the specified device, the specified device may be at least one of the following during the sensing process:

[0229] A node that generates a sensing result based on sensing measurement data;

[0230] Perception signal receiving node;

[0231] Perception signal sending node;

[0232] Node for providing perception auxiliary data.

[0233] 3) The specified device and perception method;

[0234] In an embodiment of the present application, optionally, the perception method includes at least one of the following:

[0235] The specified device spontaneously receives and sends perception signals;

[0236] The specified device sends perception signals, and other devices outside the specified device receive the perception signals;

[0237] The specified device receives perception signals, and other devices outside the specified device send the perception signals.

[0238] For example, it is indicated in the first indication information that the perception signal receiving node is the specified device and the perception method is that the specified device spontaneously receives and sends;

[0239] Or, it is indicated in the first indication information that the perception signal receiving node is the specified device and the perception method is that the specified device receives and other devices outside the specified device send perception signals;

[0240] Or, it is indicated in the first indication information that the perception signal sending node is the specified device and the perception method is that the specified device spontaneously receives and sends;

[0241] Or, it is indicated in the first indication information that the perception signal sending node is the specified device and the perception method is that the specified device sends and other devices outside the specified device receive perception signals.

[0242] 4) The type of the first perception data;

[0243] 5) Privacy protection level, which is used to indicate the type of the first perception data, and different privacy protection levels correspond to different types of the first perception data;

[0244] 6) Indication information for indicating whether the perception signal needs to be encrypted and sent;

[0245] 7) Encryption configuration information of the perception signal;

[0246] 8) Indication information for indicating whether the perception result needs to be encrypted and sent;

[0247] 9) Encryption algorithm configuration of the perception result.

[0248] Note: The subsequent process is described by taking the UE that sends the sensing request to the specified device as an example. In other embodiments of the present application, the specified device may also include multiple UEs. For example, multiple UEs of a user in a home environment or UEs of different family members. When the specified device includes multiple UEs, the network-side device needs to determine the sensing node according to the sensing authorization information of other UEs. The process of determining the sensing node according to the sensing authorization information will be described in Embodiment 3.

[0249] Step 2: The network-side device (such as the AMF) selects an appropriate Sensing Function (SF) according to the target area information or the target UE location information. An example of an implementation is that the sensing function is one of the core network functions, responsible for sensing control and / or sensing data processing. The SF can register its service area to the Network Repository Function (NRF). Then, the AMF can select the SF by querying the NRF and send a sensing request message to the SF. When the location management function (LMF) is co-located with the SF, the AMF selects the LMF (SF) and sends a sensing request message to the LMF (SF).

[0250] Step 3: The SF receives the sensing request message and determines the sensing method and the sensing node according to the first indication information in the sensing request message. If the first indication information specifies the device or the sensing method, but the SF cannot configure the specified device or the sensing method, the SF can send a message to reject the sensing request. Optionally, the message rejecting the sensing request carries a rejection reason, and the rejection reason includes that the requirements of the first indication information cannot be met. If the SF continues to perform sensing, the SF shall determine the sensing method and the sensing node according to the first indication information. For example:

[0251] If the first indication information in the sensing request message indicates that the UE that sends the sensing request message is the sensing signal sending node, the SF first determines that the UE is the sensing signal sending node, then determines the sensing method, and determines whether it is necessary to determine a device other than the UE that sends the sensing request message as the sensing signal receiving node according to the sensing method.

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

[0253] If the first indication information in the sensing request message indicates that the UE sending the sensing request message is a sensing signal sending node or a sensing signal receiving node, when the sensing mode is the sensing mode of sensing signal transceiver between the UE and other devices, the SF shall select a device other than the UE as the sensing signal receiving node or the sensing signal sending node according to the corresponding sensing mode; when the sensing mode is the UE's self-transmission and self-reception, then the SF does not need to determine the sensing signal sending node and the sensing signal receiving node.

[0254] Optionally, when the first indication information includes that the sensing signal receiving node is a specified device, the UE may also indicate whether the sensing signal is sent in an encrypted manner through the first indication information. If it is sent in an encrypted manner, optionally, the first indication information may further include the encryption configuration information of the sensing signal. The encryption configuration information of the sensing signal may be carried by the aforementioned sensing request message or by other messages.

[0255] An example of the encryption method of the sensing signal is when the required sensing result includes at least one of distance / delay, speed / Doppler. The encryption method of the sensing signal may be: after the sensing signal sending node generates the first sensing signal according to the configuration information of the traditional sensing signal, encrypt the first sensing signal to generate the first encrypted signal, and multiply the first encrypted signal by the first sensing signal (equivalent to performing phase rotation on the first sensing signal) to obtain the first target sensing signal. The generation method of the first encrypted signal is determined by the UE.

[0256] Each first sensing signal at each moment corresponds to a first encrypted signal. Each first encrypted signal contains m elements (the number of elements contained in each first encrypted signal is the same as the number of elements contained in each first sensing signal). The multiplication of the first sensing signal and the first encrypted signal may be the multiplication or conjugate multiplication in the frequency domain of the corresponding first sensing signal and first encrypted signal at each same moment. Specifically, it includes the following situations:

[0257] a) Phase-rotate the first sensing signal only in the frequency domain by the first encryption signal, at this time, the distance / delay information can be encrypted; for example, the sensing signal sending node generates the first sensing signal r(m) at the current moment, where m = 0, 1, 2…, M-1 corresponds to the frequency domain sampling points or subcarrier numbers. Among them, the first sensing signal is encrypted using a pseudo-random sequence (PN) sequence based on Quadrature Phase Shift Keying (QPSK) modulation to generate the first encryption signal r1(m), where m = 0, 1, 2…, M-1 corresponds to the frequency domain sampling points or subcarrier numbers. One way to generate the first encryption signal is the same as the way to generate the first sensing signal, using a PN sequence. However, the initialization factor for generating the PN sequence is determined and configured by the UE. When using this encryption method, the encryption configuration information is the initialization factor for generating the PN sequence.

[0258] b) Phase-rotate the first sensing signal only in the time domain by the first encryption signal, at this time, the speed / Doppler information can be encrypted;

[0259] c) Phase-rotate the first sensing signal in both the frequency domain and the time domain by the first encryption signal, at this time, the distance / delay information and the speed / Doppler information can be encrypted.

[0260] Step 4: The network-side device (AMF) determines the sensing configuration information based on the sensing request message, etc., and sends the sensing configuration information to the selected sensing signal sending node and sensing signal receiving node. When the UE is the sensing signal receiving node and the sensing signal is sent using an encryption method, the network-side device also needs to send at least one of the first encryption indication and / or the encryption configuration information of the sensing signal to the UE. The first encryption indication is used to indicate that the sensing signal sending node encrypts and sends the sensing signal, and the encryption configuration information of the sensing signal includes the initialization factor information for generating the PN sequence.

[0261] Step 5a: When the UE is the sensing signal receiving node, the UE receives the sensing signal according to the configuration information and performs sensing measurements. If the UE indicates that the sensing signal is sent using an encryption method, the UE decrypts the sensing measurement data based on the encryption configuration of the sent sensing signal to obtain the true sensing measurement data.

[0262] Step 5b: When the UE is the sensing signal sending node, the UE generates and sends the sensing signal. According to the privacy protection requirements, if the sensing measurement can only be generated and processed at the UE, and the sensing method is that the UE does not receive the sensing signal, then the UE shall encrypt the sensing signal generated based on the network configuration (a potential encryption method is as described above, that is, the UE determines and generates the first encryption signal and multiplies it with the first sensing signal (equivalent to performing phase rotation on the first sensing signal), etc.), and then sends the encrypted sensing signal. By encrypting, the real sensing measurement data cannot be obtained on the device other than the UE. Then, the UE also needs to receive the sensing measurement data sent by the sensing signal receiving node or SF of the non-UE according to the network configuration information.

[0263] Step 6: The UE generates the required sensing result based on the sensing measurement data. Considering that the UE may need the network-side device to assist in providing the sensing data processing algorithm, or the UE may need the network-side device to provide the sensing data auxiliary processing information. For example, for gesture recognition, an AI model may be required for auxiliary processing, and the network-side device may have a more suitable AI model recommendation based on historical data and experience, etc.; another example is that when the base station is the sensing signal receiving node, the UE needs the base station location information to assist in calculating the sensing result. Optionally, the UE may send a sensing data auxiliary processing request to the network-side device, and then the UE can receive the sensing data auxiliary processing information sent by the network-side device. The sensing data auxiliary processing information may include a sensing algorithm indication (such as an AI model identifier), base station location information, etc.

[0264] Embodiment 2: Sensing request initiated by the UE application function (AF)

[0265] This embodiment describes that the first device sending the sensing request is the UE application function, and usually the UE application function is processed by the application processor of the UE. The main differences from Embodiment 1 are: the network functions for receiving the sensing request message are different, and the process of selecting the sensing node based on the UE IP address included in the sensing request message sent by the UE application function. The specific process is described as follows:

[0266] Step 1: The UE application function sends a sensing request message to the NEF. The sensing request message includes first indication information. Optionally, the sensing request message further includes the UE IP address. One implementation is that the source address in the IP header of the sensing request message indicates the UE IP address, or a certain information element in the sensing request message indicates the UE IP address. Optionally, the sensing request message may further 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 event notification. The service requirements include, for example, at least one of the following: sensing resolution, sensing accuracy, frame rate, duration, target area information, time delay, sensed target information (such as vehicle type, vehicle identifier, location information).

[0267] Optionally, the first indication information includes one of the following:

[0268] 1) Indication information used to indicate whether the sensing service requested by the first device requires privacy protection;

[0269] 2) The specified device;

[0270] Optionally, the specified device includes the UE that sends the sensing request, or other devices associated with the sensing request.

[0271] In an embodiment of the present application, optionally, the specified device includes at least one of a terminal, a base station, and a sensing function.

[0272] In order for the first sensing data to be generated or processed by the specified device, the specified device may be at least one of the following during the sensing process:

[0273] A node that generates a sensing result based on sensing measurement data;

[0274] A sensing signal receiving node;

[0275] A sensing signal sending node;

[0276] A node that provides sensing auxiliary data.

[0277] 3) The specified device and the sensing method;

[0278] In an embodiment of the present application, optionally, the sensing method includes at least one of the following:

[0279] The specified device spontaneously sends and receives sensing signals;

[0280] The specified device sends sensing signals, and other devices outside the specified device receive the sensing signals;

[0281] The specified device receives the sensing signal, and other devices outside the specified device send the sensing signal.

[0282] For example, the first indication information indicates that the sensing signal receiving node is the specified device and the sensing method is that the specified device sends and receives by itself;

[0283] Or, the first indication information indicates that the sensing signal receiving node is the specified device and the sensing method is that the specified device receives and other devices outside the specified device send the sensing signal;

[0284] Or, the first indication information indicates that the sensing signal sending node is the specified device and the sensing method is that the specified device sends and receives by itself;

[0285] Or, the first indication information indicates that the sensing signal sending node is the specified device and the sensing method is that the specified device sends and other devices outside the specified device receive the sensing signal.

[0286] 4) The type of the first sensing data;

[0287] 5) The privacy protection level, which is used to indicate the type of the first sensing data, and different privacy protection levels correspond to different types of the first sensing data;

[0288] 6) Indication information used to indicate whether the sensing signal needs to be encrypted for transmission;

[0289] 7) Encryption configuration information of the sensing signal;

[0290] 8) Indication information used to indicate whether the sensing result needs to be encrypted for transmission;

[0291] 9) Encryption algorithm configuration of the sensing result.

[0292] Note: The subsequent process is described by taking the specified device as the UE where the UE application function that sends the sensing request is located as an example.

[0293] Step 2: The NEF performs a sensing authorization check on the sensing request of the UE application function. After the sensing authorization is passed, the NEF selects a suitable SF according to the target area information or the target object location information. One implementation of the NEF performing a sensing authorization check on the sensing request of the UE application function is as follows: The sensing authorization information of the UE can be stored in the NEF or the UDM. If it is stored in the UDM, the NEF can request authorization verification from the UDM. The NEF obtains the sensing authorization information from the UDM and performs the sensing authorization check. For example, if the UE does not allow a certain type of service or APP to obtain the sensing measurement data or sensing results related to the UE, the NEF rejects the sensing request. From the perspective of the UE user, the sensing measurement data or sensing results include the environmental information around the UE, which is a relatively private type of data. If a certain type of service or APP hopes to obtain the sensing measurement data or sensing 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.

[0294] Step 3: After the NEF sensing authorization check is passed, in one implementation, the NEF selects a suitable AMF and sends a sensing request message to the AMF. Then the AMF selects a suitable SF. The specific method can be: The NEF queries the UE ID in the mobile network (such as the Subscription Permanent Identifier (SUPI), etc.) from the SMF according to the UE IP address information contained in the sensing request message. The NEF selects a suitable AMF according to the AMF to which the UE is attached. Then the AMF selects a suitable SF according to the first indication information and the sensing service type, etc. In another implementation, the NEF selects a suitable SF and sends a sensing request message to the SF. The specific method can be: The NEF determines a suitable SF according to the sensing request message (such as including the first indication information, the sensing service type, the sensing area, the sensing target, etc.). Then the SF queries the UE ID in the mobile network (such as SUPI, etc.) from the SMF according to the UE IP address information contained in the sensing request message. The SF can obtain the AMF to which the UE is attached according to the UE ID and send the UE ID to the AMF to query the serving cell and the neighboring cells of the serving cell of the UE, etc.

[0295] Step 4: The SF determines the sensing method and the sensing node according to the first indication information. When the first indication information has specified the device or the sensing method, if the SF cannot configure the specified device or the sensing method, then the SF can send a message rejecting the sensing request. Optionally, the message rejecting the sensing request carries a rejection reason, and the rejection reason includes the requirement that cannot be met by the first indication information. If the SF continues to perform sensing, then the SF should determine the sensing method and the sensing node according to the first indication information. For example:

[0296] If the first indication information in the sensing request message indicates that the UE where the UE application function sending the sensing request message is located is a sensing signal sending node, then the SF first determines that the UE is a sensing signal sending node, then determines the sensing method, and determines whether it is necessary to determine a device other than the UE sending the sensing request message as a sensing signal receiving node according to the sensing method.

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

[0298] If the first indication information in the sensing request message indicates that the UE where the UE application function sending the sensing request message is located is a sensing signal sending node or a sensing signal receiving node, when the sensing method is the sensing method of sensing signal transceiver between the UE and other devices, the SF shall select a device other than the UE as a sensing signal receiving node or a sensing signal sending node according to the corresponding sensing method; when the sensing method is self-transmission and self-reception of the UE, then the SF does not need to determine a sensing signal sending node and a sensing signal receiving node.

[0299] Optionally, when the first indication information includes that the sensing signal receiving node is a specified device, the UE can also indicate whether the sensing signal is sent in an encrypted manner through the first indication information. If it is sent in an encrypted manner, optionally, the first indication information can also include the encryption configuration information of the sensing signal. The encryption configuration information of the sensing signal can be carried by the foregoing sensing request message or by other messages.

[0300] An example of the encryption method of the sensing signal is when the required sensing result includes at least one of distance / delay, speed / Doppler. The encryption method of the sensing signal can be: after the sensing signal sending node generates a first sensing signal according to the configuration information of the traditional sensing signal, encrypts the first sensing signal to generate a first encrypted signal, and multiplies the first encrypted signal by the first sensing signal (equivalent to performing phase rotation on the first sensing signal) to obtain a first target sensing signal. The generation method of the first encrypted signal is determined by the UE.

[0301] Each first sensing signal at each moment corresponds to a first encrypted signal. Each first encrypted signal contains m elements (the number of elements contained in each first encrypted signal is the same as the number of elements contained in each first sensing signal). The multiplication of the first sensing signal and the first encrypted signal can be the multiplication or conjugate multiplication of the corresponding first sensing signal and first encrypted signal in the frequency domain at each same moment. Specifically, it includes the following situations:

[0302] a) Rotate the phase of the first sensing signal only in the frequency domain through the first encryption signal, and at this time, the distance / delay information can be encrypted. For example, the sensing signal sending node generates the first sensing signal r(m) at the current moment, where m = 0, 1, 2…, M - 1 corresponds to the frequency domain sampling points or subcarrier numbers. Among them, the first sensing signal is encrypted using a pseudo-random sequence (PN sequence) based on quadrature phase shift keying (QPSK) modulation to generate the first encryption signal r1(m), where m = 0, 1, 2…, M - 1 corresponds to the frequency domain sampling points or subcarrier numbers. One way to generate the first encryption signal is the same as the generation method of the first sensing signal, using a PN sequence. However, the initialization factor for generating the PN sequence is determined and configured by the UE. When using this encryption method, the encryption configuration information is the initialization factor for generating the PN sequence.

[0303] b) Rotate the phase of the first sensing signal only in the time domain through the first encryption signal, and at this time, the speed / Doppler information can be encrypted.

[0304] c) Rotate the phase of the first sensing signal in both the frequency domain and the time domain through the first encryption signal, and at this time, the distance / delay information and the speed / Doppler information can be encrypted.

[0305] Step 5: The network-side device determines the sensing configuration information based on the sensing request message, etc., and sends the sensing configuration information to the selected sensing signal sending node and sensing signal receiving node. When the UE is the sensing signal receiving node and the sensing signal is sent in an encrypted manner, the network-side device also needs to send at least one of the first encryption indication and / or the encryption configuration information of the sensing signal to the UE. The first encryption indication is used to indicate that the sensing signal sending node encrypts the sensing signal before sending, and the encryption configuration information of the sensing signal includes the initialization factor information for generating the PN sequence.

[0306] Step 6a: When the UE is the sensing signal receiving node, the UE receives the sensing signal according to the configuration information and performs sensing measurements. If the UE indicates that the sensing signal is 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 real sensing measurement data.

[0307] Step 6b: When the UE is a sensing signal sending node, the UE generates and sends a sensing signal. According to the privacy protection requirements, if the sensing measurement can only be generated and processed at the UE and the sensing method is that the UE does not receive the sensing signal, then the UE should encrypt the sensing signal generated based on the network configuration (a potential encryption method is as described above, that is, the UE determines and generates a first encryption signal and multiplies it with the first sensing signal (equivalent to performing phase rotation on the first sensing signal), etc.), and then sends the encrypted sensing signal. Through encryption, the real sensing measurement data cannot be obtained on the device other than the UE. Then, the UE also needs to receive the sensing measurement data sent by the sensing signal receiving node or SF of the non-UE according to the network configuration information.

[0308] Step 7: The UE generates the required sensing result based on the sensing measurement data. Considering that the UE may need the network-side device to assist in providing the sensing data processing algorithm, or the UE may need the network-side device to provide the sensing data assistance processing information. For example, for gesture recognition, an AI model may be required for assistance processing, and the network-side device may have a more suitable AI model recommendation based on historical data and experience, etc.; another example is that when the base station is a sensing signal receiving node, the UE needs the base station location information to assist in calculating the sensing result. Optionally, the UE may send a sensing data assistance processing request to the network-side device, and then the UE can receive the sensing data assistance processing information sent by the network-side device. The sensing data assistance processing information may include a sensing algorithm indication (such as an AI model identifier), base station location information, etc.

[0309] Embodiment 3: Sensing request initiated by an application function not deployed on the UE

[0310] This embodiment describes that the first device sending the sensing request is an application function, and 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:

[0311] Step 1: Optionally, the UE reports its sensing capabilities, and the sensing capabilities include the ability of the first device to generate a sensing result based on the sensing measurement data. Since the ability of the first device to generate a sensing result based on the sensing measurement data is usually closely related to the storage and computing capabilities of the first device, it can be characterized by reporting the sensing capabilities. The sensing result may be a sensing result related to the user's vital signs or the user's private area. Optionally, the sensing result may include at least one of the following: respiratory rate, intrusion detection, gesture recognition, and motion monitoring, etc.

[0312] Step 2: Optionally, the UE sends sensing authorization information to the network-side device. The sensing authorization information includes at least one of the following: the identifier of the application function that is allowed to request the sensing service (such as the APP name or IP address and port number, etc.), the type of sensing service allowed to be requested by the application function, and the type of sensing data allowed to be requested by the application function. The application function includes at least one of the UE application function and the network-side application function. Optionally, the information included in the sensing authorization information is related to the user's vital signs or private area. For example, it allows the health monitoring APP 1 to request the sensing results / sensing service type 1 (such as breathing monitoring) in area A (such as a certain private room).

[0313] Step 3: The application function sends a sensing request message to the NEF. The sensing request message includes first indication information. Optionally, the first indication information may include a specified device identifier list (such as a mobile phone number, IP address, etc.). Optionally, the first indication information may further include: indication information for indicating whether the sensing signal needs to be encrypted for transmission and / or encryption configuration information of the sensing signal. Optionally, the first indication information may further include: indication information for indicating whether the sensing result needs to be encrypted for transmission and / or encryption algorithm configuration of the sensing result. Optionally, the sensing request message may further 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 event notification. The service requirements include, for example, at least one of the following: sensing resolution, sensing accuracy, frame rate, duration, target area information, time delay, sensed target information (such as vehicle type, vehicle identifier, location information).

[0314] Optionally, the first indication information includes one of the following:

[0315] 1) Indication information for indicating whether the sensing service requested by the first device requires privacy protection;

[0316] 2) The specified device;

[0317] Optionally, the specified device includes the UE that sends the sensing request, or other devices associated with the sensing request.

[0318] In an embodiment of the present application, optionally, the specified device includes at least one of a terminal, a base station, and a sensing function.

[0319] In order for the first sensing data to be generated or processed by the specified device, the specified device may be at least one of the following during the sensing process:

[0320] A node that generates a sensing result based on sensing measurement data;

[0321] A sensing signal receiving node;

[0322] Perception signal sending node;

[0323] Node for providing perception auxiliary data.

[0324] 3) The specified device and perception method;

[0325] In an embodiment of the present application, optionally, the perception method includes at least one of the following:

[0326] The specified device spontaneously sends and receives perception signals;

[0327] The specified device sends perception signals, and other devices outside the specified device receive the perception signals;

[0328] The specified device receives perception signals, and other devices outside the specified device send the perception signals.

[0329] For example, the first indication information indicates that the perception signal receiving node is the specified device and the perception method is that the specified device spontaneously sends and receives;

[0330] Or, the first indication information indicates that the perception signal receiving node is the specified device and the perception method is that the specified device receives and other devices outside the specified device send perception signals;

[0331] Or, the first indication information indicates that the perception signal sending node is the specified device and the perception method is that the specified device spontaneously sends and receives;

[0332] Or, the first indication information indicates that the perception signal sending node is the specified device and the perception method is that the specified device sends and other devices outside the specified device receive perception signals.

[0333] 4) The type of the first perception data;

[0334] 5) Privacy protection level, which is used to indicate the type of the first perception data, and different privacy protection levels correspond to different types of the first perception data;

[0335] 6) Indication information for indicating whether the perception signal needs to be encrypted and sent;

[0336] 7) Encryption configuration information of the perception signal;

[0337] 8) Indication information for indicating whether the perception result needs to be encrypted and sent;

[0338] 9) Encryption algorithm configuration of the perception result.

[0339] Step 4: The NEF performs a sensing authorization check on the sensing request of the application function. After the sensing authorization is passed, the NEF selects a suitable SF according to the target area information or the target object location information. One implementation method for the NEF to perform a sensing authorization check on the sensing request of the application function is as follows: The sensing authorization information of the UE can be stored in the NEF or the UDM. If it is stored in the UDM, the NEF can request authorization verification from the UDM. The NEF obtains the sensing authorization information from the UDM and performs the sensing authorization check. For example, if the UE does not allow a certain type of service or APP to obtain the sensing measurement data or sensing results related to the UE, the NEF rejects the sensing request. From the perspective of the UE user, the sensing measurement data or sensing results include the environmental information around the UE, which is a relatively private type of data. If a certain type of service or APP hopes to obtain the sensing measurement data or sensing 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.

[0340] Step 5: After the NEF sensing authorization check is passed, in one implementation method, the NEF selects a suitable AMF and sends a sensing request message to the AMF. Then the AMF selects a suitable SF. The specific method can be: The NEF queries the UE ID in the mobile network (such as the Subscription Permanent Identifier (SUPI), etc.) from the SMF according to the UE IP address information contained in the sensing request message. The NEF selects a suitable AMF according to the AMF to which the UE is attached. Then the AMF selects a suitable SF according to the first indication information and the sensing service type, etc. in the sensing request message. In another implementation method, the NEF selects a suitable SF and sends a sensing request message to the SF. The specific method can be:

[0341] The NEF determines a suitable SF according to the sensing request message (such as including the first indication information, sensing service type, sensing area, sensing target, etc.). Then the SF queries the UE ID in the mobile network (such as SUPI, etc.) from the SMF according to the UE IP address information contained in the sensing request message. The SF can obtain the AMF to which the UE is attached according to the UE ID and send the UE ID to the AMF to query the serving cell and the neighboring cells of the serving cell of the UE, etc.

[0342] Step 6: The SF determines the sensing method and sensing nodes according to the first indication information. When the first indication information has specified a device or a sensing method, the SF needs to perform a sensing authorization check on the specified device. One 5G protocol-based method is for the SF to obtain sensing authorization information from the UDM and perform the sensing authorization check. For example, if a UE in the specified device identifier list included in the sensing request message does not allow the APP to make the request or does not allow the APP to request a certain sensing service, the SF rejects the sensing request. The reason for rejection is that the specified device authorization has not been obtained. If the sensing continues, then the SF shall determine the sensing method and sensing nodes according to the first indication information. For example:

[0343] If the first indication information in the sensing request indicates that the sensing service requested by the first device requires privacy protection, but does not indicate the sensing signal sending node, the sensing signal receiving node, the sensing method, etc. Then the SF can determine the sensing signal sending node, the sensing signal receiving node, the sensing method, etc. according to the specified device identifier list, the sensing authorization information, etc.

[0344] If the first indication information in the sensing request indicates that the specified device A is the sensing signal sending node, then the SF first determines that the device A is the sensing signal sending node, then determines the sensing method, and determines whether a device other than the device A needs to be used as the sensing signal receiving node according to the sensing method.

[0345] If the first indication information in the sensing request indicates that the specified device A is the sensing signal receiving node, then the SF first determines that the device A is the sensing signal receiving node, then determines the sensing method, and determines a device other than the device A as the sensing signal sending node according to the sensing method.

[0346] If the first indication information in the sensing request indicates that the specified device A is the sensing signal sending node or the sensing signal receiving node, when the sensing method is the sensing method of sensing signal transceiver between the device A and other devices, the SF shall select a device other than the device A as the sensing signal receiving node or the sensing signal sending node according to the corresponding sensing method; when the sensing method is self-transmission and self-reception of the device A, then the SF does not need to determine the sensing signal sending node and the sensing signal receiving node.

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

[0348] Step 7: The network-side device determines the sensing configuration information based on the sensing request message, etc., and sends the sensing configuration information to the selected sensing signal sending node and sensing signal receiving node. When it is indicated in the sensing request message that the sensing signal needs to be sent in an encrypted manner, the network-side device also needs to send at least one of a first encryption indication and / or the encryption configuration information of the sensing signal to the sensing signal sending node. The first encryption indication is used to indicate that the sensing signal sending node encrypts the sensing signal before sending, and the encryption configuration information of the sensing signal includes PN sequence generation initialization factor information. At the same time, the network-side device also needs to send the encryption configuration information of the sensing signal to the sensing signal receiving node. If the application function that sends the sensing request message requires the sensing result, then the network-side device sends the sensing result transmission configuration information to the specified device that generates the sensing result. The sensing result transmission configuration information includes an application function identifier (such as APP name or IP address and port number, etc.). Optionally, if the sensing request message indicates that the sensing result needs to be sent in an encrypted manner, then the network-side device also needs to send an encryption indication for encrypting the sensing result and / or the encryption algorithm configuration for the sensing result to the specified device that generates the sensing result. The encryption algorithm is, for example, AES, SNOW 3G, ZUC, etc. Among them, in order to avoid the sensing result being parsed when transmitted over the 3GPP network, the key information, etc. used in each encryption algorithm is configured by the application function.

[0349] Step 8a: When the specified 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, then the specified 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 specified device A is the sensing signal sending node, the specified device A generates and sends the sensing signal according to the configuration information.

[0351] Step 9: The designated device (which can be designated device A or other designated devices) obtains the perception measurement data and generates the required perception results based on the perception measurement data. Considering 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 the perception data assistance processing information. For example, for gesture recognition, an AI model may be required for assistance processing, and the network-side device may have a more suitable AI model recommendation based on historical data and experience, etc.; for another example, when the base station is used as the perception signal receiving node, the designated device needs the base station location information to assist in calculating the perception results. Optionally, the designated device may send a perception data assistance processing request to the network-side device, and then the designated device can receive the perception data assistance processing information sent by the network-side device. The perception data assistance 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 can be designated device A or other designated devices) sends the generated perception results to the application function. It should be noted that the data sent in this step belongs to user data, so it is transparent to the 3GPP network function.

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

[0354] This embodiment elaborates on indicating privacy protection through the definition of privacy protection levels. The specific process is elaborated 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). The perception request message includes first indication information. Optionally, the perception request message may further 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 event notification. The service requirements include, for example, at least one of the following: perception resolution, perception accuracy, frame rate, duration, target area information, time delay, perceived target information (such as vehicle type, vehicle identifier, location information).

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

[0357] An example of the definition of a privacy protection level is shown as follows. The numbers in the example are for illustration only and are not specifically limited:

[0358] The first privacy protection level (which can also be referred to as level 1 or the first level, etc., only for the purpose of explaining the number, and the name is not limited to this), and the first privacy protection level is used to indicate that the perception result is generated or processed by a specified device; that is to say, 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 (which can also be referred to as level 2 or the second level, etc.), and the second privacy protection level is used to indicate that the perception auxiliary data and the perception result are generated or processed by a specified device; usually, the perception result needs to be generated in combination with the location of the UE that sends or receives the perception signal, or perception auxiliary data such as an environmental map. For the first privacy protection level, other devices that obtain the perception auxiliary data may also calculate the corresponding perception result, while in the second privacy protection level, the perception auxiliary data does not leave the specified device, which further reduces the probability of non-specified devices obtaining the perception result in the case where the perception result needs to be generated based on the perception auxiliary data.

[0360] The third privacy protection level (which can also be referred to as level 3 or the third level, etc.), and the third privacy protection level is used to indicate that the perception measurement data and the perception result are generated or processed by a specified device; this means that the perception measurement data is generated or processed on the specified device. When a non-specified device cannot obtain the perception measurement data, compared with the first privacy protection level, it also further reduces the probability of non-specified devices obtaining the perception result and related information.

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

[0362] The fifth privacy protection level (which can also be referred to as level 5 or the fifth level, etc.), and the fifth privacy protection level is used to indicate that the perception auxiliary data, the perception measurement data, and the perception result are generated or processed by a specified device, and the perception method is that the specified device spontaneously sends and receives perception signals.

For the specific implementation method, please refer to the corresponding steps in Embodiments 1 - 3, which will not be elaborated here.

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

[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 measures the received signals and then processes the measurement results to obtain the desired sensing results. Therefore, the configuration of the sensing signal can also be referred to as the configuration of the sensing measurement object, including at least one of the following:

[0386] 1) Waveform, 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), pulse signals, etc.;

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

[0388] 3) Guard interval: The time interval between the end of signal transmission and the time when the latest echo signal of the signal is received; this parameter is proportional to the maximum sensing distance; for example, it can be calculated by 2dmax / c, where dmax is the maximum sensing distance (belonging to the sensing requirement). For a self-transmitting and self-receiving sensing signal, dmax represents the maximum distance from the sensing signal transceiver point to the signal transmission point; in some cases, the Cyclic Prefix (CP) of an OFDM signal can act 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 (belonging to the sensing requirement);

[0390] 5) Burst duration: This parameter is inversely proportional to the rate resolution (belonging to the sensing requirement). This parameter is the time span of the sensing signal, mainly for calculating the Doppler frequency shift; this parameter can be calculated by c / 2 / delta_v / fc; where, delta_v is the velocity resolution; fc is the signal carrier frequency or the center frequency of the signal;

[0391] 6) Time domain interval: This parameter can be calculated by c / 2 / fc / v_range; where, v_range is the maximum speed minus the minimum speed (belonging to the sensing requirement); this parameter is the time interval between two adjacent sensing signals;

[0392] 7) Transmission power of the sensing signal, e.g., taking values every 2 dBm from -20 dBm to 23 dBm;

[0393] 8) Transmission port information of the sensing signal, including the number and port number, etc.;

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

[0395] 10) Signal direction; e.g., the direction of the sensing signal (such as the base station transmits and the UE receives, or the base station receives and the UE transmits, or the base station transmits and receives by itself, base station-to-base station transmission and reception, UE transmits and receives by itself, UE-to-UE transmission and reception)

[0396] 11) Beam information of the sensing signal;

[0397] 12) Time resources, e.g., the time slot index or symbol index of the time slot where the sensing signal is located; Among them, time resources are divided into two types. One is one-time time resources, e.g., transmitting an omnidirectional first signal in one symbol; the other is non-one-time time resources, e.g., multiple groups of periodic time resources or discontinuous time resources (which may include start time and end time), and the same direction of sensing signal is transmitted in each group of periodic time resources, and the beam directions are different on different groups of periodic time resources;

[0398] 13) Frequency resources, including the center frequency point, bandwidth, Resource Block (RB) or subcarrier, etc. of the sensing signal. When the first node transmits the information of the second node, this center frequency point is the center frequency point of the second node. If the second node supports multiple cells, then this list of center frequencies includes the center frequency points corresponding to multiple cells. For communication modes such as Sidelink in New Radio (NR), the sensing measurement object is a set of transmission resource pools used for Sidelink communication in NR on a single carrier frequency.

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

[0400] The sensing measurement parameters are configured to indicate the sensing measurement parameters for the sensing measurement node to measure at least one of the following:

[0401] 1) First-level measurement parameters (also known as received signal / raw channel information), including at least one of the following: received signal / channel response complex result, amplitude / phase, I / Q channels and their operation results (operations include at least one of the following: addition, subtraction, multiplication, division, matrix addition, subtraction, multiplication, matrix transpose, trigonometric relationship operations, square root operation, power operation, etc., and threshold detection results, maximum / minimum value extraction results, etc. of the above operation results; optionally, operations also include 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, digital filtering, etc., and threshold detection results, maximum / minimum value extraction results, etc. of the above operation results);

[0402] 2) Second-level measurement parameters (also known as basic measurement parameters), including at least one of the following: delay, Doppler, angle, signal strength, and their multi-dimensional combined representation;

[0403] 3) Third-level measurement parameters (also known as sensing results), including at least one of the following: whether the target exists, distance, speed, angle / orientation, RCS, acceleration, position, trajectory, action, expression, breathing frequency, heart rate, imaging result, weather, air quality, material and composition, etc.

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

[0405] 1) Indication of the access type used for report transmission, 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 indication of the access type used for report transmission is 5G and 4G, it means that 5G is preferred to transmit the report.

[0406] 2) Report criteria: The criteria for triggering the sensing measurement node to send a measurement report can be periodic, event-triggered, or indication-based reporting. The events include but are not limited to the following:

[0407] 2a) The quality of the sensed signal detected by the receiving end reaches the threshold requirement, such as at least one of the ratio of the average signal power to the average noise power (Signal-to-Noise Ratio, SNR), the reference signal received power (Reference Signal Received Power, RSRP), the received signal strength indication (Received Signal Strength Indication, RSSI), and the signal clutter ratio threshold. If the threshold is reached, then measure the sensed measurement quantities and reports in the sensed measurement item configuration;

[0408] 2b) The sensed measurement results obtained by the receiving end do not meet the sensing requirements, that is, the sensing performance indicators corresponding to the calculated sensed measurement results meet or are not lower than the preset threshold. For example, sensed SNR (one potential definition is the ratio of the effective signal power of the signal propagation path corresponding to the sensing target to the noise power, or defined as the ratio of the effective signal power of the signal propagation path corresponding to the sensing target to the sum of the noise power and the signal power of the signal propagation paths corresponding to non-sensing targets);

[0409] 2c) The receiving end correctly demodulates the data (such as passing the cyclic redundancy check (CRC)). Sensing is performed based on the communication data, and the method of demodulating first and then estimating the sensing parameters is adopted. If the communication demodulation is incorrect, the sensed measurement results are affected and become unreliable;

[0410] 2d) The mandatory perception measurement options meet the requirements. For example, the time delay, Doppler, and Global Positioning System (GPS) location information of the perception signal are mandatory perception measurement options, while the Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) are optional. In this case, a report is made only when multiple mandatory perception measurement items are available.

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