[0051] In one embodiment, the communication system 100 may further include other network entities such as a Mobility Management Entity (MME) and an Access and Mobility Management Function (AMF), which is not limited in this embodiment of the present application.

[0052] Among them, the network equipment may include access network equipment and core network equipment. That is, the wireless communication system also includes multiple core networks for communicating with the access network equipment. The access network equipment can be an evolutionary base station (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), pico base station, access point (AP), transmission point (TP) or new generation base station (new generation Node B, gNodeB), etc. in a long-term evolution (LTE) system, a next-generation (mobile communication system) (next radio, NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

[0053] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in Figure 1 as an example, the communication device may include a network device and a terminal device having a communication function. The network device and the terminal device may be specific devices in the embodiments of the present application and will not be described in detail here. The communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0054] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0055] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association.

[0057] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0058] Figure 2 illustrates an exemplary 5G network system architecture. The UE establishes an access stratum connection with the access network (AN) via the Uu wireless interface, exchanging access stratum messages and wireless data transmission. The UE establishes a non-access stratum (NAS) connection with the access and mobility management function (AMF) via the N1 interface, exchanging NAS messages. The AMF is the access and mobility management function network element in the core network. The session management function (SMF) is the session management function network element in the core network. In addition to managing UE mobility, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The policy control function (PCF) is the policy management function network element in the core network, responsible for formulating policies related to UE mobility management, session management, and billing. The user plane function (UPF) is the user plane function network element in the core network, communicating with external data networks via the N6 interface and with the AN (or radio access network (RAN)) via the N3 interface.

[0059] Current cellular networks, including 5G networks, are used solely for communication. However, the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception, such as user motion or gesture recognition, respiratory monitoring, terminal speed measurement, environmental imaging, and weather monitoring. Therefore, in the future, cellular networks may be used not only for communication and data transmission but also for acquiring sensory information.

[0060] Currently, discussions are underway to support perception capabilities in Beyond 5G (B5G) networks, and to support perception functions in 3GPP networks by adding a perception control network element (Sensing Function) and corresponding processes. As shown in Figure 3, this is a possible flowchart for controlling access network devices or UEs to perform UE-level perception operations. The application sends a perception request for the target UE to the core network of the 3GPP network. The core network selects the correct access network device or target UE through the perception control network element or AMF, triggers the ability to perform perception-related wireless measurements, starts measuring perception information, and generates perception results. The target UE can also be an auxiliary UE.

[0061] Examples of the main wireless sensing modes of synaesthesia (communication and perception) integration are as follows:

[0062] 1. Base station echo sensing (single gNB autonomous sensing): The base station sends a sensing signal and receives an echo signal.

[0063] 2. Inter-base station sensing (gNB-gNB sensing): Base station B receives the sensing signal sent by base station A.

[0064] 3. Air interface uplink sensing (UE-gNB uplink sensing): The base station receives the sensing signal sent by the terminal;

[0065] 4. Air interface downlink perception (UE-gNB downlink perception): The terminal receives the perception signal sent by the base station;

[0066] 5. Terminal echo perception (single UE autonomous transmission and reception): The terminal sends a perception signal and receives an echo signal;

[0067] 6. Inter-terminal perception (UE-UE perception): Terminal B receives the perception signal sent by terminal A.

[0068] In the early stages of B5G communication perception integration, consideration should be given to reusing relevant air interface signals as much as possible to perform perception behaviors without introducing too much air interface enhancement; and considering the complexity of full-duplex implementation, perception between terminals and / or base stations is the priority.

[0069] Figure 3 shows a UE-level (Per-UE) perception process. Figure 4 shows a region-level (Per-Area) perception process.

[0070] As shown in Figure 3, the perception process may specifically include: Step 301: The application function (AF) sends a perception request for the target UE (which may include UE information, perception type, etc.) to the core network of the 3GPP network. Step 302: The perception control network element sends a perception instruction (which may include UE information, perception type, etc.) to the AMF. Step 303: The AMF determines the UE perception mode or the base station perception mode.

[0071] Optionally, in step 304, the AMF sends a sensing instruction (which may include a sensing type, etc.) to the access network device. In step 305, the access network device performs access layer signal measurement with the target UE. In step 306, the access network device generates sensing data.

[0072] Optionally, in step 307, the AMF sends a sensing instruction (which may include a sensing type, etc.) to the target UE. In step 308, access layer signal measurements are performed between the access network device and the target UE. In step 309, the target UE generates sensing data.

[0073] As shown in Figure 4, the perception process may specifically include: Step 401, AF sends a perception request to the core network (which may include a first target area, a perception type, etc.). Step 402, the perception control network element of the core network sends a perception instruction to the AMF (which may include a second target area, a perception type, etc.). Step 403, the AMF determines the perception base station. Step 404, the AMF sends a perception instruction to the access network device (which may include a third target area, a perception type, etc.). Step 405, the access network device determines the auxiliary UE or base station. Step 406, access layer signal measurement is performed between the access network device and the auxiliary UE or base station. Step 407, the access network device generates perception data.

[0074] The main difference between the perception processes in Figures 3 and 4 is that the UE-level perception process includes a specific UE as the perception target, which is "active perception"; while in the area-level perception process, its perception target is a specific area or object, which does not belong to 3GPP and does not have a specific UE, which is "passive perception".

[0075] Configuration of relevant positioning reference signals

[0076] The positioning architecture primarily consists of the UE, multiple gNBs, the AMF, and the LMF (Location Management Function). In the first step, the UE and / or gNB transmits an SRS (Sounding Reference Signal) and / or a PRS (Positioning Reference Signal) according to a known configuration pattern. The gNB and / or UE then measures the SRS and / or PRS according to the known configuration pattern, obtaining positioning-related measurements such as angle of departure, angle of arrival, distance, and range difference. Finally, these measurements are aggregated by the UE or LMF for positioning, generating the final positioning result.

[0077] The following describes a positioning method based on multi-RTT (Multi-Round Trip Time) to illustrate the configuration of SRS and PRS and their measurement.

[0078] As shown in Figure 5, in step 3a, the gNB configures uplink SRS resources for the terminal. Then, in step 5a, the network activates the terminal to transmit SRS. In step 6, the LMF (Location Management Function) informs each nearby gNB of the terminal's SRS resource configuration via an NRPPa (New Radio Positioning Protocol A) measurement request and requests each gNB to measure the SRS transmitted by the terminal. Furthermore, in step 9b, the network performs uplink (UL) SRS measurements. In step 11, each gNB reports its collected measurement results to the LMF. Furthermore, for downlink measurements, in steps 7 and 8, the network first sends each gNB's unique downlink (DL) PRS configuration information to the terminal and then activates the terminal to perform downlink measurements, such as the DL PRS measurement in step 9a. Then in step 10, the terminal sends the measurement result to the LMF via the LPP (LTE Positioning Protocol) Provide Location Information message (ProvideLocationInformation msg).

[0079] Related UE positioning measurement result reporting process

[0080] As shown in Figure 6, in step 601, the Request Location Information message in the LPP message is used by the location server (LMF) to request the positioning measurement results or position estimation results from the target device. The Request Location Information message reflects the positioning method and reporting method selected by the positioning system.

[0081] For example, the RequestLocationInformation IE (Information Element) of LPP includes commonIEsRequestLocationInformation (Common Information Element Request Location Information). This field specifies the location information type requested by the location server and optionally other configuration information associated with the requested location information.

[0082] That is, the commonIEsRequestLocationInformation IE included in the LPP RequestLocationInformation specifies the configuration related to the result reporting.

[0083] If the system decides to apply a certain positioning method, the system will further include IE corresponding to the specific method, such as nr-Multi-RTT-RequestLocationInformation-r16.

[0084] For example, CommonIEsRequestLocationInformation carries a common IE of the LPP message type requesting location information. Some fields of CommonIEsRequestLocationInformation are as follows:

[0085] triggeredReporting TriggeredReportingCriteria OPTIONAL,--Cond ECID

[0086] periodicalReporting PeriodicalReportingCriteria OPTIONAL,--Need ON

[0087] triggeredReporting (trigger reporting), this IE indicates a request for triggered reporting. It is configurable only for the Enhanced Cell-ID (E-CID) or NR E-CID method and contains the following subfields:

[0088] cellChange: If this field is set to TRUE, the target device provides requested location information each time the primary cell has changed.

[0089] reportingDuration: Maximum duration of triggered reporting in seconds. A value of zero is interpreted to mean an unlimited(ie "infinite") duration. The target device should continue triggered reporting for the reportingDuration or until an LPP Abort or LPP Error message is received.

[0090] Periodical Reporting: This IE indicates a request for periodic reporting and contains the following subfields:

[0091] reportingAmount: Indicates the number of periodic location information reports requested. Enumerated values ​​correspond to 1, 2, 4, 8, 16, 32, 64, or infinite / indefinite number of reports. If the reportingAmount is 'infinite / indefinite', the target device shou-ld continue periodic reporting until an LPP Abort message is received. The value 'ra1' shall not be used by a sender.

[0092] The reportingInterval represents the interval between location information reports and the response time requirement for the first location information report. Enumeration values ​​may include ri0-25, ri0-5, ri1, ri2, ri4, ri8, ri16, ri32, and ri64, corresponding to reporting intervals of 1, 2, 4, 8, 10, 16, 20, 32, and 64 seconds, respectively. When the reportingInterval expires before the target device can obtain a new measurement value or a new position estimate, a measurement report that does not contain a measurement value or a position estimate is required. A value of "noPeriodicalReporting" indicates that it should not be used by the sender (reportingInterval indicates the interval between location information reports and the response time requirement for the first location information report. Enumerated values ​​ri0-25,ri0-5,ri1,ri2,ri4,ri8,ri16,ri32,ri64correspond to reporting intervals of 1,2,4,8,10,16,20,32,and 64 seconds, respectively. Measurement reports containing no measurements or no location estimate are required when a reportingInterval expires before a target device is able to obtain new measurements or obtain a new location estimate. The value 'noPeriodicalReporting'shall not be used by a sender.).

[0093] Based on the above field description, it can be seen that the periodic reporting field is included to configure periodic reporting. In particular, for the E-CID method, the triggered reporting field is included to configure event-triggered reporting. During the maximum duration of the triggered reporting, when the primary cell changes, the terminal reports the requested location information to the network.

[0094] In the relevant positioning measurement result reporting process, the main supported reporting method is periodic reporting, and event-triggered reporting is only supported in the E-CID method. Positioning measurement results can be reported by providing a message with location information (PrivideLocationInformation) (see steps S602 and S603).

[0095] Regarding perception, on the one hand, perception measurement results may contain a larger amount of data than positioning measurement results. On the other hand, in certain perception scenarios (such as intrusion detection), although the network may configure perception nodes to periodically measure perception reference signals, in most cases, perception measurement results are likely to be stable with minimal variance. Therefore, periodically transmitting a large number of redundant perception measurement results with minimal variance would result in unnecessary data and / or signaling transmission overhead.

[0096] FIG7 is a schematic flow chart of a method 700 for reporting perception information according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0097] S710. A first communication device receives first configuration information, where the first configuration information is used to indicate a perception information reporting event.

[0098] In an embodiment of the present application, the first communication device may be a terminal device. The first communication device may receive first configuration information from a second communication device, such as a network device or another terminal device. The first configuration information may indicate a perception information reporting event for the first communication device. After receiving the first configuration information, the first communication device may determine whether the perception information satisfies the perception information reporting event, and thereby determine the information to be reported. Compared to periodic reporting, reporting by the first communication device based on the perception information reporting event can reduce redundancy, thereby reducing unnecessary data and / or signaling transmission overhead.

[0099] In the embodiment of the present application, the perception information reporting event can be understood as the perception information reporting criteria. Satisfying the perception information reporting event can be understood as satisfying the perception information reporting criteria, or can be understood as the occurrence or emergence of the perception information reporting event.

[0100] In one embodiment, the first configuration information includes at least one of the following:

[0101] Perception information threshold;

[0102] The change threshold of the perceived information;

[0103] A timer that triggers the reporting of perception information;

[0104] The counter that triggers the reporting of perception information.

[0105] In the embodiment of the present application, the perception information may also be referred to as a perception measurement result. The first communication device may measure the perception reference signal to obtain the perception measurement result.

[0106] In this embodiment of the present application, the perception information reporting event indicated by the first configuration information may include the perception information meeting a perception information threshold, the change in the perception information meeting a perception information change threshold, the timer meeting a certain value, the counter meeting a certain value, etc. A corresponding relationship may exist between the perception reference signal, the perception information, and the perception information reporting event. Based on the perception reference signal and the corresponding relationship between the perception reference signal and the perception information reporting event, the first communications device determines whether the perception information obtained by measuring the perception reference signal meets the corresponding perception information reporting event, and further determines how to perform subsequent reporting operations.

[0107] In an embodiment of the present application, a perception information reporting event of the first communication device may be determined based on a combination of one or more of a threshold, a timer, and a counter included in the first configuration information. For example, a perception information reporting event may be determined based on a timer and a counter that triggers perception information reporting. For another example, a perception information reporting event may be determined based on a perception information change threshold and a timer that triggers perception information reporting.

[0108] In one embodiment, the perception information reporting event corresponding to the first configuration information includes at least one of the following:

[0109] The signal strength measured by the sensing reference signal is less than the configured signal strength threshold;

[0110] The signal strength measured by the sensing reference signal is greater than or equal to the configured signal strength threshold;

[0111] The signal strength change obtained by measuring the sensing reference signal is less than the configured signal strength change threshold;

[0112] The signal strength change obtained by measuring the sensing reference signal is greater than or equal to the configured signal strength change threshold;

[0113] The delay variation obtained by measuring the sensing reference signal is greater than or equal to the configured delay variation threshold;

[0114] The Doppler frequency shift change obtained by measuring the sensing reference signal is greater than or equal to the configured frequency shift change threshold;

[0115] The change in original channel information obtained by measuring the sensing reference signal is greater than or equal to the configured channel information change threshold;

[0116] The variation of the elements in the perception information matrix obtained by measuring the perception reference signal is greater than or equal to the variation threshold of the signal strength;

[0117] The value of the timer corresponding to the sensing target is greater than or equal to the value of the configured timer for triggering sensing information reporting;

[0118] The value of the counter corresponding to the perception target is greater than the value of the configured trigger perception information reporting counter.

[0119] The above examples of perception information reporting events are not exhaustive. In actual application scenarios, more types of perception information reporting events may be provided depending on the perception reference signal to be measured and the perception information to be requested. The first communications device may, when one perception information reporting event is satisfied, report the perception information measured for the perception reference signal for the perception information reporting event, or may, when multiple perception information reporting events are satisfied, report the perception information measured for the perception reference signal involved in the perception information reporting event.

[0120] In one implementation, the first configuration information is in a first message, and the first message is sent via Radio Resource Control (RRC) signaling and / or NAS signaling.

[0121] In one embodiment, the first message is a request for awareness information message. The first message can reuse the request for awareness information message or be a message with another name, which can be configured according to specific needs. For example, the first configuration information can be a triggered reporting information element (triggeredReporting IE) in the first message.

[0122] In one embodiment, as shown in FIG8 , based on the above method 700, the method 800 further includes: S810, the first communication device receives second configuration information, and the second configuration information is used to configure a perception reference signal. There are many types of perception reference signals, such as CSI-RS (Channel-State-Information Reference Signal, downlink channel state information reference signal), PRS (Positioning Reference Signal), SRS, or a reference signal specifically used for perception. The second configuration information includes configuration information of the time-frequency domain resources of the reference signal, such as subcarrier spacing, cyclic prefix length, frequency domain resource bandwidth, frequency domain starting frequency position, frequency domain reference point, comb tooth size, transmission period and time slot offset, repetition factor, etc. After receiving the second configuration information, the first communication device can determine the perception reference signal that needs to be measured. For example, if the second configuration information includes the configuration information of PRS, the perception reference signal that the first communication device needs to measure is the PRS resource.

[0123] In one implementation, the second configuration information is in a second message, and the first message is sent via RRC signaling and / or NAS signaling.

[0124] In one embodiment, the second message is a provide auxiliary data message. The second message can be multiplexed into the provide auxiliary data message, or can be a message with another name, which can be set according to specific needs.

[0125] In one implementation, the second configuration information carries information of the second communication device that sends the perception reference signal.

[0126] In one embodiment, the second communication device includes at least one of the following:

[0127] Network equipment;

[0128] a terminal device that sends the first message;

[0129] The terminal device receives the first message.

[0130] In this embodiment of the present application, the device that transmits the perception reference signal can be a network device or a terminal device. For example, the second configuration information received by terminal device A carries information about the perception reference signal and information about the network device that transmits the perception reference signal. For another example, the second configuration information received by terminal device A carries information about the perception reference signal and information about terminal device A that transmits the perception reference signal. For another example, the second configuration information received by terminal device A carries information about the perception reference signal and information about terminal device B that transmits the perception reference signal.

[0131] In one embodiment, the method 800 further includes: S820, the first communications device receives third configuration information, where the third configuration information is used to indicate requested perception information. There are various types of perception information or perception measurement results, such as RSRP (Reference Signal Received Power), latency, Doppler shift, channel information, whether a perception target exists, etc. After receiving the third configuration information, the first communications device may determine the type of perception information of the perception reference signal that needs to be measured. For example, if the third configuration information includes RSRP, the first communications device needs to measure the RSRP of the PRS resource.

[0132] In one embodiment, the third configuration information is used to indicate at least one of the following perception information requested by the second communication device:

[0133] Original channel information;

[0134] Basic measurement quantities;

[0135] Perceive the target's attributes;

[0136] Sense the target's status.

[0137] For example, the original channel information may also be referred to as received signal information, which may include the complex result, amplitude, phase, I path, Q path, and related operation results of the received signal or channel response.

[0138] Basic modulation schemes include amplitude, frequency, and phase modulation. The modulated signal can be represented using polar coordinates of amplitude and phase (vector). I / Q modulation is widely used in digital communications due to its high spectral efficiency. IQ modulation uses two carrier waves: an in-phase (I) component and a quadrature (Q) component, with a 90° phase shift between them. Therefore, the I channel represents the in-phase component, and the Q channel represents the quadrature component.

[0139] For another example, the basic measurement quantity may include one or more of time delay, Doppler frequency shift, angle, signal strength, etc.

[0140] For example, the properties or states of the perceived target may include distance, speed, direction, acceleration, whether the target exists, spatial position, trajectory, movement, expression, etc.

[0141] In one implementation, the third configuration information is in a third message, and the third message is sent via RRC signaling and / or NAS signaling.

[0142] In one embodiment, the third message is a request for awareness information message. The third message can reuse the request for awareness information message, or can be a message with another name, which can be set according to specific needs.

[0143] In one embodiment, the method 800 further includes:

[0144] S830: The first communication device measures a perception reference signal to obtain the perception information.

[0145] In one embodiment, the method 800 further includes:

[0146] S840: When the perception information satisfies a perception information reporting event, the first communication device sends the perception information to the second communication device.

[0147] In one embodiment, the sensing information is in a Provide Sensing Information message (ProvideSensingInformation). The first communication device may report the sensing information obtained by measuring the sensing reference signal by sending the Provide Sensing Information message to the second communication device.

[0148] In one embodiment, the method 800 further includes:

[0149] S850: When the perception information does not satisfy a perception information reporting event, the first communication device sends indication information to the second communication device, where the indication information is used to indicate a change in the perception information.

[0150] In one embodiment, the indication information is in a provide perception information message. The first communication device can report changes in perception information obtained by measuring the perception reference signal by sending the provide perception information message to the second communication device.

[0151] For example, the first communications device determines whether the perception information obtained by measuring the perception reference signal satisfies a corresponding perception information reporting event. If so, the first communications device may report the measured perception information to the device requesting the perception information. If not, the first communications device may not report the measured perception information; may report partial measured perception information; or may only report indication information indicating that the perception information has a minor change.

[0152] In the embodiments of the present application, the first configuration information, the second configuration information, and the third configuration information can be transmitted via the same message, or via different messages, or any two configuration information can be transmitted via the same message. Therefore, the steps of receiving the first configuration information, the second configuration information, and the third configuration information can be combined or separated depending on the different transmission messages. In addition, in the embodiments of the present application, there is no restriction on the timing of the steps of receiving the first configuration information, the second configuration information, and the third configuration information.

[0153] In this embodiment of the present application, after receiving the first, second, and third configuration information, the first communications device may measure the perception reference signal indicated by the second configuration information to obtain the perception information requested by the second communications device as indicated by the third configuration information. Based on the first configuration information, the first communications device then determines whether the measured perception information meets the perception information reporting event. If so, the perception information is reported. If not, indication information may be reported to indicate that the perception information has changed slightly.

[0154] In the embodiment of the present application, the perception information reporting event is used to more reasonably report the perception information and reduce unnecessary reporting overhead.

[0173] In one implementation, the first configuration information is in a first message, and the first message is sent via RRC signaling and / or NAS signaling.

[0175] In one embodiment, as shown in FIG10 , based on the above method 900 , the method 1000 further includes:

[0176] S1010. A second communication device sends second configuration information, where the second configuration information is used to configure a perception reference signal.

[0187] Original channel information;

[0188] Basic measurement quantities;

[0191] In one implementation, the third configuration information is in a third message, and the third message is sent via RRC signaling and / or NAS signaling.

[0198] In one embodiment, the indication information is in a providing awareness information message.

[0199] For a specific example of the second communication device executing method 800 of this embodiment, reference can be made to the relevant description of the network device, such as a base station, or the receiving terminal device in the above method 700, which will not be repeated here for the sake of brevity.

[0200] Example 1: Interaction between UE and network equipment:

[0201] When a network device (e.g., gNB, LMF, AMF, or SF) initiates a sensing session between the UE and the network device (e.g., gNB, LMF, AMF, or SF) based on a sensing request (e.g., MT-SR, MO-SR, or NI-SR), the following steps are included, as shown in Figure 11:

[0202] S1110 and S1120. The UE and network device (gNB, LMF, AMF, or SF) perceive capabilities and interact. A server (e.g., a network device) sends a RequestCapabilities message to a target device (e.g., a UE). The target device returns a ProvideCapabilities message to the server.

[0203] S1130. The UE receives a Provide Assistance Data message sent by a network device (gNB, LMF, AMF, or SF), where the message carries configuration information of the perception reference signal (i.e., an example of the second configuration information). The message may be sent via RRC (Radio Resource Control) and / or NAS dedicated signaling.

[0204] The above-mentioned perception reference signal can be sent by the gNB (UE-gNB downlink perception), sent by other UEs participating in perception (UE-UE perception), or sent by the current UE itself (UE autonomous perception). Therefore, the message can also carry gNB and / or UE ID information related to the perception reference signal sending node.

[0205] S1140. The UE receives a Request Sensing Information message sent by a network device (gNB, LMF, AMF, or SF), which includes configuration information for indicating the requested sensing information (i.e., an example of the third configuration information) and configuration information for event-triggered sensing information reporting (such as triggeredReporting IE) (i.e., an example of the first configuration information). The message can be sent via RRC and / or NAS dedicated signaling.

[0206] a. The configuration information used to indicate the requested perception information is mainly used to indicate that the network device (gNB, LMF, AMF or SF) requires different levels of perception information. For specific examples, see Table 1:

[0207] Table 1

[0208]

[0209] b. The configuration information for event-triggered perception information reporting (triggeredReporting IE) may include at least one of a perception information threshold, a perception information change threshold, a perception information reporting timer, and a counter for triggering perception information reporting.

[0210] If the perception information required by the network device (gNB, LMF, AMF or SF) is a combination of different perception information, multiple different thresholds can be configured for different perception information, and the reporting criteria (or reporting events) can be that one of these perception information meets the conditions, or all of them meet the conditions.

[0211] In Example 1, the network configures the UE to report signal strength and indicates a corresponding signal strength threshold: when the RSRP (Reference Signal Received Power) of the UE's measured reference signal is greater than / less than the RSRP threshold, the measurement result is triggered to be reported.

[0212] Example 2: For the intrusion detection scenario (perception target detection), the network configures the reporting delay, Doppler shift, or original channel information reflecting the channel response, and indicates the corresponding change threshold: when the UE measures the delay, Doppler shift, or original channel information reflecting the channel response obtained by measuring the perception reference signal, the measurement result is triggered to be reported.

[0213] Example 3: For an intrusion detection scenario (sensing target detection), the network is configured to report whether the target exists, and to configure a sensing information reporting timer and a counter to trigger sensing information reporting:

[0214] (1) The counter that triggers the reporting of perception information is initially set to 0.

[0215] (2) If the UE receives indication information from the lower layer, it indicates that the presence of the sensing target is detected.

[0216] (2-1) The UE starts or restarts the perception information reporting timer.

[0217] (2-2) The counter for triggering the reporting of perception information increases by 1.

[0218] (2-3) If the counter that triggers the perception information reporting is greater than or equal to the maximum value set by the network:

[0219] (2-3-1) Triggering the reporting of perception information, the UE reports the presence of the detected perception target.

[0220] (2-3-2) Set the counter for triggering perception information reporting to 0.

[0221] (3) If the perception information reporting timer times out, the counter for triggering perception information reporting is set to 0.

[0222] Example 4: The network configures a range-Doppler matrix for reporting sensing information, where the horizontal axis represents delay / distance, the vertical axis represents Doppler shift / speed, and the value represents signal strength. Furthermore, a signal strength change threshold is configured to trigger reporting. A criterion for triggering reporting is:

[0223] (1) If the UE has not reported the perception information since it configured perception measurement and reporting; or

[0224] (2) If the change of any element in the range-Doppler matrix obtained by the UE measuring the sensing reference signal is greater than or equal to the signal strength change threshold, the UE triggers the reporting of the sensing information range-Doppler matrix (Range-Doppler Matrix).

[0225] S1150. The UE performs measurement of the perception reference signal according to the above configuration and obtains corresponding perception information.

[0226] S1160. If the perception information obtained by the UE meets the configured perception information reporting criteria, the UE sends a Provide Sensing Information message to the network device (gNB, LMF, SF or AMF), which carries the corresponding perception information.

[0227] Optionally, if the perception information reporting criteria are not met, the complete perception information may not be reported, but only indication information may be reported to indicate that the perception information has a minor change.

[0228] S1170. The network device (gNB, LMF, SF or AMF) obtains the perception result based on the perception information reported by the UE, and chooses to complete or continue the current perception session, or start a new perception session.

[0229] Example 2: Interaction between UEs

[0230] In the OOC (Out of Coverage) scenario, the UE cannot access the network, so sensing operations cannot be performed under the control of the network device (gNB, LMF, AMF, or SF). In the OOC scenario, the network / network device (gNB, LMF, AMF, or SF) in Example 1 can be changed to a sensing server UE (a terminal with sensing server functionality).

[0231] After the Sensing server UE initiates a sensing session (Sensing Session) between the UE and the Sensing server UE based on the sensing request, the specific implementation process is similar to that of Example 1.

[0232] In an embodiment of the present application, the terminal triggers the reporting of perception information based on a configured perception information reporting event. For example, the UE performs perception reference signal measurement and obtains the requested perception information based on the configuration information of the perception reference signal sent by the network device (gNB, LMF, AMF, or SF) or the Sensing server UE, the configuration information for indicating the requested perception information, and the configuration information for event-triggered perception information reporting, and decides whether to trigger perception information reporting. The solution of the embodiment of the present application can reduce unnecessary reporting overhead by introducing event-triggered perception information reporting.
