[0060] It should be noted that the perception categories shown in Table 1 above are merely illustrative examples, and the categories of perception measurements are not limited in this application embodiment.

[0061] Furthermore, the embodiments of this application can be applied to integrated communication and sensing scenarios.

The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, improved spectrum efficiency, and reduced mutual interference, thereby improving the overall system performance.

[0063] In this embodiment, depending on the different transmitting and receiving nodes of the sensing signal, there may be, but is not limited to, the six sensing links shown in Figure 2. It should be noted that each sensing link in Figure 2 is illustrated with one transmitting node and one receiving node. In actual systems, different sensing links can be selected according to different sensing requirements. Each sensing link may have one or more transmitting and receiving nodes, and the actual sensing system may include multiple different sensing links. Furthermore, the sensing targets in Figure 2 are people and vehicles as examples, and it is assumed that neither people nor vehicles carry or have installed signal transceiver equipment. The sensing targets in actual scenarios will be much more diverse.

[0069] Sensing Link 6: Sidelink sensing between terminals. For example, terminal 2 receives a sensing signal sent by terminal 1 and obtains a sensing result, or terminal 1 receives a sensing signal sent by terminal 2 and obtains a sensing result.

[0070] In some embodiments, signaling transmission between radio access network devices and terminals, and between different terminals, may be via Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), Layer 1 signaling, or other newly defined sensing signaling; signaling transmission between sensing network functions and terminals may be via Non-Access-Stratum (NAS) signaling (forwarded via AMF), or via RRC signaling, MAC CE, Layer 1 signaling, or other newly defined sensing signaling; interaction between sensing network functions and base stations may be via AMF forwarding to the radio access network through the N2 interface; or the core network sensing network function may send the signal to the UPF, which in turn sends it to the radio access network through the N3 interface; or the signal may be sent to the radio access network (e.g., a base station) through a newly defined interface; signaling transmission between radio access network devices may be via the Xn interface.

[0071] In some embodiments, the sensing network function can also be called a sensing network element or sensing management function (Sensing MF). It can be located on the RAN side or the core network side. It refers to a network node in the core network or RAN that is responsible for at least one of the following functions: sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It can be an upgrade based on the AMF or LMF in the mobile communication network, or it can be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing network function / sensing network element may include at least one of the following:

[0072] The system interacts with wireless signal transmitting devices or wireless signal measuring devices (including target terminals or base stations serving the target terminals or associated with the target area) to exchange target information.

The wireless signal can also be referred to as the sensing signal.

[0073] The sensing method used is determined based on factors such as the type of sensing service, the information of sensing service consumers, the required Quality of Service (QoS) requirements, the sensing capabilities of the wireless signal transmitting equipment, and the sensing capabilities of the wireless signal measuring equipment. This sensing method may include: wireless access network device A transmitting and wireless access network device B receiving, or wireless access network device transmitting and terminal receiving, or wireless access network device A transmitting and receiving, or terminal transmitting and receiving, or terminal A transmitting and terminal B receiving, etc.

[0074] The sensing equipment serving the sensing service is determined based on factors such as the type of sensing service, information about the sensing service consumers, the required sensing QoS requirements, the sensing capabilities of the wireless signal transmitting equipment, and the sensing capabilities of the wireless signal measuring equipment.

[0083] The following description, in conjunction with the accompanying drawings, details a sensing and measurement method, apparatus, and device provided in this application through some embodiments and application scenarios.

[0084] Please refer to Figure 3, which is a flowchart of a sensing measurement method provided in an embodiment of this application. As shown in Figure 3, it includes the following steps:

[0085] Step 301: The first device acquires the first information;

[0086] The first information includes at least one of the following:

[0087] Perception-related indicators obtained by measuring the first signal;

[0088] The sensing measurement results obtained by measuring the first signal;

[0089] Device information of the first device.

[0090] The aforementioned first device can be a terminal or a network-side device.

[0091] The acquisition of the first information can be achieved by the first device through measurement, or by the first device through a sensor.

[0092] The above-mentioned measurement of the first signal can be performed by the first device receiving the first signal sent by the second device and measuring it, that is, the first device is the receiving device of the first signal.

[0093] The above-mentioned measurement of the first signal can be performed by the first device sending the first signal and performing the measurement, that is, the first device is the device that sends the first signal, such as the device transmitting and receiving the measurement itself.

[0094] In this embodiment of the application, the first signal may be a dedicated signal for sensing services or a communication signal, such as a reference signal or a synchronization signal.

[0095] Among them, the dedicated signal for sensing services can be a sensing signal generated based on chirp or frequency modulated continuous wave (FMCW) signals, or a sensing signal generated based on pseudo-random (PN) sequences or ZC (Zadoff Chu) sequences, etc.

[0096] The reference signal can be a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), or a positioning reference signal (PRS), etc.

[0097] The aforementioned synchronization signal can be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS), etc.

[0098] The aforementioned signals carrying communication data can be Physical downlink shared channel (PDSCH), Physical uplink shared channel (PUSCH), Physical downlink control channel (PDCCH), or Physical uplink control channel (PUCCH), etc.

[0099] The aforementioned perception-related indicators may be perception-related indicators obtained by the first device during the measurement process of the first signal, or they may be perception-related indicators obtained by the first device during the process of receiving the first signal.

[0100] The aforementioned perception-related indicators refer to indicators associated with perception, such as indicators that affect the perception target or indicators that affect perception measurement. Specifically, they can be the measured values ​​or values ​​of perception-related indicators.

[0101] The above-mentioned sensing measurement results can be the measurement results of at least one sensing measurement quantity.

[0102] The equipment information of the aforementioned first device may include at least one of the following:

[0103] The direction of movement of the equipment, the speed of movement of the equipment, the location information of the equipment, and the orientation information of the equipment.

[0104] The orientation information of the device can refer to the orientation information of specific components of the device, such as the orientation information of antennas, sensors, screens, etc.

[0105] The aforementioned device information may be obtained by the first device based on its own sensor devices, or it may be obtained by the first device based on the first signal it receives.

[0106] The aforementioned preset conditions can be defined by a protocol, or conditions obtained by the first device through receiving information sent by the second device, such as conditions obtained through broadcast signaling, System Information Block (SIB), RRC signaling, MACCE, Layer 1 signaling, or data channels.

[0107] In this embodiment of the application, the second device may be a terminal or a network-side device, or a network sensing function. When the first device is a terminal, the second device may be a terminal or a network-side device, or a network sensing function. When the first device is a network-side device, the second device may be a terminal or a network-side device, or a network sensing function.

[0108] Step 302: When the first information meets the preset conditions, the first device performs sensing and measurement actions.

[0109] The first device performing the sensing and measurement behavior when the first information meets the preset conditions can be understood as the first device performing the sensing and measurement behavior when the first information meets the preset conditions, and not performing the sensing and measurement behavior or stopping the execution of the sensing and measurement behavior when the first information does not meet the preset conditions.

[0110] In this embodiment of the application, the above steps can enable the first device to perform sensing and measurement actions when the first information meets the preset conditions, thereby reducing the number of times the sensing and measurement actions are performed and thus saving the overhead of sensing and measurement.

[0111] In addition, since the aforementioned first information includes perception-related indicators, the first device can perform perception measurement actions more reliably. This is because the validity of the perception measurement results is closely related to the perception-related indicators, making it easier to avoid the first device performing unnecessary perception measurement actions.

[0112] Since the aforementioned first information includes the sensing measurement results, the first device can perform sensing measurement actions more reliably because it is easier to avoid the first device performing unnecessary sensing measurement actions through the sensing measurement results.

[0113] The aforementioned first information includes the device information of the first device, which can effectively prevent the first device from performing unnecessary sensing and measurement actions, thereby making the first device's sensing and measurement actions more reliable.

[0114] As an optional implementation, the sensing and measurement behavior includes at least one of the following:

[0115] The first signal is measured to obtain the sensing measurement result;

[0116] Send the sensing measurement results;

[0117] Send the perception-related indicators;

[0118] Send the device information, which is used for sensing;

[0119] Send an instruction message indicating that the first device can participate in sensing;

[0120] A second signal is sent, which is used for sensing.

[0121] Wherein, if the first information does not include the perception-related indicators obtained by measuring the first signal, that is, if the judgment of the preset conditions does not consider the perception-related indicators obtained by measuring the first signal (such as only considering device information or perception measurement results for the preset conditions), the perception measurement behavior may or may not include the above-mentioned sending perception-related indicators, which can be determined according to actual needs.

[0122] When the aforementioned first information includes the sensing measurement result obtained by measuring the first signal, the sensing measurement behavior does not include the sensing measurement result obtained by measuring the first signal; the sensing measurement behavior including the sensing measurement result obtained by measuring the first signal can be implemented when the first information includes the aforementioned device information or sensing-related indicators.

[0123] If the first information mentioned above does not include the sensing measurement results obtained by measuring the first signal, that is, if the judgment of the above preset conditions does not consider the sensing measurement results obtained by measuring the first signal (such as only considering device information or sensing-related indicators for the above preset conditions), the sensing measurement behavior may or may not include sending the sensing measurement results, which can be determined according to actual needs.

[0124] If the first information does not include the device information of the first device, that is, if the judgment of the above preset conditions does not consider the device information, the above sensing and measurement behavior may or may not include sending the device information of the first device, which can be determined according to actual needs.

[0125] The aforementioned device information for sensing refers to the device receiving the aforementioned device information using the aforementioned device to perform sensing-related calculations during the sensing process.

[0126] The second signal mentioned above can be a dedicated signal used for sensing services, or a communication signal, such as a reference signal or a synchronization signal. For details, please refer to the corresponding description of the first signal mentioned above, which will not be repeated here.

[0127] The aforementioned sending of the second signal refers to the first device sending the second signal to other devices, which then perform sensing-related measurements on the second signal, or the first device sending the aforementioned second signal and performing measurements, i.e., the first device performing self-transmission and self-reception measurements.

[0128] In one of the above optional embodiments, since at least one of the above-mentioned sensing and measurement actions is performed when the first information meets the preset conditions, the overhead of sensing and measurement can be saved.

[0129] As an optional implementation, the perception-related indicators include at least one of the following:

[0130] Sensing metrics related to received power;

[0131] Perception metrics related to interference or noise power;

[0132] Sensing metrics related to received power, as well as interference or noise power.

[0133] The aforementioned sensing metrics related to received power may include at least one of the following:

[0134] Sensing metrics related to the received power of the target signal and sensing metrics related to the received power of the signal path of the target signal associated with the sensing target. For example, the aforementioned sensing metrics related to received power include: a first metric, which indicates the received power of the signal path of the first signal associated with the sensing target, that is, the first metric is used to indicate the received power of the signal path of at least one signal path of the first signal associated with the sensing target.

[0135] The signal path associated with the aforementioned sensing target can be a signal path affected by the sensing target or a signal path that passes through the sensing target.

[0136] In one of the above optional embodiments, since the perception-related indicators include perception indicators related to received power, it is possible to determine whether to perform a perception measurement action based on the received power, thereby making the execution of the perception measurement action more reliable. Alternatively, it is also possible to determine whether to perform a perception measurement action based on the received power of the signal path associated with the perception target. The received power of the signal path associated with the perception target more directly reflects whether the perception measurement action is necessary. Therefore, the above-mentioned first indicator can make the perception measurement action more reliable.

[0137] In some embodiments, the aforementioned first indicator may be the linear average value (in W) of the received power of the signal path associated with the sensing target in the channel response measured from the first signal over the resource unit carrying the first signal. This resource unit can be a time-domain or frequency-domain resource unit. Using a linear average value makes the received power more accurate and reliable. It should be noted that the embodiments of this application do not limit the received power to a linear average value. For example, in some embodiments, it may also be the median received power, the lowest received power, or the highest received power.

[0138] The aforementioned perception index related to interference or noise power can refer to the perception index being associated with at least one of interference and noise, such as a perception index associated with interference power, a perception index associated with noise power, or an interference index associated with both interference and noise power.

[0139] In one of the above optional embodiments, since the perception-related indicators include perception indicators related to interference or noise power, interference or noise can be taken into account when determining whether to perform a perception measurement action, so as to make the perception measurement action more reliable.

[0140] Optionally, the perception metric related to the interference or noise power includes at least one of the following:

[0141] The second indicator is the sum of the linear average power of the signal paths other than the signal path associated with the sensing target in the channel response of the first signal on the target resource and the linear average power of the interference or noise power from other signals other than the first signal on the first resource; or, the second indicator is equal to the difference between the total received power and the first indicator, wherein the total received power is the total received power of the first device on the target resource, or the total received power is the power corresponding to the Received Signal Strength Indication (RSSI) of the first device on the first resource;

[0142] The third indicator is the linear average of the interference or noise power from signals other than the first signal on the second resource, or the third indicator is equal to the difference between the total received power and the received power of the first signal, where the total received power is the total received power of the first device on the target resource, or the total received power is the power corresponding to the RSSI of the first device on the first resource.

[0143] The fourth indicator is the linear average power of the signal paths other than the signal path associated with the sensing target in the channel response of the first signal on the target resource; or, the fourth indicator is equal to the difference between the received power of the first signal and the first indicator.

[0144] Wherein, the first index is used to indicate the received power of the signal path associated with the sensing target in the signal path of the first signal, the target resource is the transmission resource of the first signal, the first resource includes the target resource or at least one resource other than the target resource, and the second resource includes the target resource or at least one resource other than the target resource.

[0145] The aforementioned other signal paths can be all or part of the signal paths in the first signal other than those associated with the perceived target.

[0146] Other signals besides the first signal mentioned above can refer to all or some of the signals detected by the first device on the first resource, excluding the first signal.

[0147] The aforementioned first resource, including the target resource or at least one resource other than the target resource, means that the first resource includes at least one of the following:

[0148] The target resource, and at least one other resource besides the target resource.

[0149] The aforementioned second resource, including the target resource or at least one resource other than the target resource, means that the second resource includes at least one of the following:

[0150] The target resource, and at least one other resource besides the target resource.

[0151] In this context, at least one resource other than the target resource can refer to at least one resource other than the target resource among the resources that the first device needs to detect or receive signals from, such as resources configured by higher-layer signaling or resources that the first device has predetermined to detect or receive signals from.

[0152] The aforementioned interference or noise power includes the sum of interference power and noise power, or interference power or noise power.

[0153] The total received power of the first device on the target resource may include the received power of signals from the serving cell and non-serving cells on the target resource, adjacent channel interference power, and thermal noise power, etc. Furthermore, the total received power may also be a linear average of the total received power of the first device on the target resource (in W).

[0154] The power corresponding to the RSSI of the first device on the first resource can be the total received power = RSSI * K1, where K1 is a coefficient, which can be a protocol convention or a network-side configuration. In some embodiments, the power corresponding to the RSSI can also be the RSSI itself, i.e., the total received power = RSSI.

[0155] The received power of the first signal mentioned above refers to the reference signal received power (RSRP) of the first signal.

[0156] The second indicator mentioned above is equal to the difference between the total received power and the first indicator, which can be expressed as: Second indicator = Total received power - First indicator.

[0157] The aforementioned third indicator is equal to the difference between the total received power and the received power of the first signal, and can be expressed as: Third indicator = Total received power - First signal received power.

[0158] The aforementioned fourth index is equal to the difference between the received power of the first signal and the first index, and can be expressed as: Fourth index = Received power of the first signal - First index.

[0159] In the above embodiments, the second index allows interference or noise from signal paths other than the signal path associated with the sensing target and signals other than the first signal to be considered when determining whether to perform a sensing measurement action, thus making the sensing measurement action more reliable.

[0160] In the above embodiments, the third indicator allows interference or noise from signals other than the first signal to be considered when determining whether to perform a sensing measurement action, thus making the sensing measurement action more reliable.

[0161] In the above embodiments, the fourth index allows the power of signal paths other than those associated with the sensing target to be considered when determining whether to perform a sensing measurement action, thus making the sensing measurement action more reliable.

[0162] The aforementioned perception index, which is related to both received power and interference or noise power, refers to a perception index that is related to both received power and interference or noise power.

[0163] In one of the above-mentioned alternative embodiments, since the sensing-related indicators include sensing indicators related to received power as well as those related to interference or noise power, it is possible to take into account received power and interference or noise when determining whether to perform a sensing measurement action, so as to make the sensing measurement action more reliable.

[0164] In some implementations, the sensing metrics related to received power, and also related to interference or noise power, include at least one of the following:

[0165] The fifth indicator is equal to the quotient obtained by dividing the first indicator by the second indicator;

[0166] The sixth indicator is equal to the quotient obtained by dividing the first indicator by the third indicator;

[0167] The seventh indicator is equal to the quotient obtained by dividing the first indicator by the fourth indicator;

[0168] The eighth index is equal to the product of the quotient of the first index divided by the total received power and the target coefficient.

[0169] The first, second, third, and fourth indicators mentioned above are the same as those described in the above implementation method, and will not be repeated here. It should be noted that, when at least one of the fifth, sixth, seventh, and eighth indicators is included, the perception-related indicators in the embodiments of this application may or may not include the first, second, third, and fourth indicators.

[0170] The aforementioned target coefficient can be represented as K2, such as the eighth indicator = K2 * the first indicator / total received power, where K2 is the coefficient, and K2 can be a protocol agreement or a network-side configuration.

[0171] In this embodiment, by using the fifth, sixth, seventh or eighth indicators mentioned above, the receiving power and interference or noise can be taken into account when determining whether to perform a sensing measurement action, so as to make the sensing measurement action more reliable.

[0172] In some implementations, the aforementioned sensing metrics related to received power, and also related to interference or noise power, may include at least one of the following:

[0173] Metrics related to the perceived signal-to-interference plus-noise ratio (SINR), perceived signal-to-noise ratio (SNR), perceived signal-to-interference ratio (SIR), and perceived reference signal received quality (RSRQ).

[0174] As an optional implementation, the signal path associated with the sensing target satisfies at least one of the following:

[0175] The parameter meets the first preset threshold, or the parameter is within the first preset range.

[0176] The parameters meet the preset modulation rules;

[0177] The parameter difference with the first signal path satisfies the second preset threshold, or the parameter difference with the first signal path is within the second preset range;

[0178] The parameter difference with the reference signal path satisfies the third preset threshold, or the parameter difference with the reference signal path is within the third preset range.

[0179] The above parameters may include at least one of the following:

[0180] Amplitude, power, intensity, energy, phase, Doppler, time delay, angle.

[0181] The above parameter difference may include at least one of the following:

[0182] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, time delay difference, and angle difference.

[0183] The first preset threshold, the first preset interval range, the second preset threshold, the second preset interval range, the third preset threshold, and the third preset interval range can be agreed upon by the protocol or configured on the network side. Alternatively, these preset thresholds or preset interval ranges can be determined by the receiving device based on prior sensing information or sensing requirements. The parameters satisfying the first preset threshold can be defined as the parameters exceeding or equaling the first preset threshold. The parameter difference between the parameters and the first received signal path satisfying the second preset threshold can be defined as the parameter difference between the parameters and the first received signal path exceeding or equaling the second preset threshold. The parameter difference between the parameters and the reference signal path satisfying the third preset threshold can be defined as the parameter difference between the parameters and the reference signal path exceeding or equaling the third preset threshold.

[0184] For example, if the sensing service is moving target detection, then the signal path with a Doppler greater than zero needs to be detected as the signal path associated with the sensing target; or for a traffic scenario where the sensing target is a vehicle, with a default vehicle speed of 40km / h to 120km / h, then the signal path within the corresponding speed range (Doppler range) needs to be detected as the signal path associated with the sensing target; or if the distance between the sensing target area and the sensing signal transceiver needs to meet specific requirements, then the signal path within the corresponding time delay range needs to be detected as the signal path associated with the sensing target; or if the sensing service is respiratory monitoring, then the corresponding normal breathing rate can be determined based on the person's gender and age (e.g., 15 to 30 breaths / minute, which can be used as prior information for sensing, and the corresponding Doppler range of 0.25 to 0.5Hz can be calculated).

[0185] The aforementioned first-arrival signal path can be a line-of-sight (LOS) path, specifically the path of the first signal to reach the receiver. The aforementioned reference signal path can be a signal path reflected by a known target, such as a signal path reflected by a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.

[0186] The aforementioned preset modulation rules can be agreed upon by the protocol or configured on the network side. Specific modulation rules are the modulation rules of tags, backscatter devices, or RIS, that is, the path associated with the sensed target can be the signal path that has been modulated and reflected by the tag, backscatter device, or RIS.

[0187] In one of the above optional embodiments, the signal path associated with the sensing target can be determined in multiple ways, which can improve the flexibility of determining the signal path associated with the sensing target, and can also improve the accuracy of determining the signal path associated with the sensing target by combining multiple methods.

[0188] In some implementations, before determining the signal path associated with the sensing target, a set of signal paths can be determined. This set includes signal paths whose amplitude, power, intensity, or energy exceeds a certain threshold, as shown in Figure 4. The signal path set includes signal paths 0, 1, 2, and 3. The signal path associated with the sensing target is then determined from this set based on at least one of the aforementioned criteria to reduce computational complexity.

[0189] The following example illustrates the calculation of indicators in the embodiments of this application. It should be noted that the calculation of each indicator in the embodiments of this application is not limited, and the following example is only an illustration.

[0190] The first indicator is calculated in the following way:

[0191] The first device (e.g., a terminal) performs channel estimation based on the transmitted target signal X(k) and the corresponding received signal Y(k), obtaining the channel response H(k) = Y(k) / X(k), where k = 0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units. After obtaining the channel response H(k), the first device transforms it to the target dimension and determines the signal path associated with the perceived target in the target dimension. Then, it calculates the power of the signal path associated with the perceived target as a first indicator. If the signal path associated with the perceived target includes multiple signal paths, the sum of the power of the multiple signal paths is calculated as the first indicator.

[0192] The target dimension includes one of the following:

[0193] Time delay dimension;

[0194] Dopplerweis;

[0195] Azimuth dimension;

[0196] Pitch angle;

[0197] A dimension that combines at least two of the following: time delay dimension, Doppler dimension, azimuth dimension, and pitch dimension. For example, time delay-Doppler dimension, time delay-Doppler-angle dimension, etc.

[0198] For example, H(f) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling points (e.g., subcarrier index). Then, by performing an inverse Fourier transform on H(f), it can be transformed to the time delay dimension (target dimension). As another example, H(f,t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling points (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling points (e.g., orthogonal frequency-division multiplexing). For example, if H(f,t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), t = 0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., OFDM symbol index), and s = 0, 1, 2, ..., P-1 represents the spatial domain sampling point (antenna index or port index), then H(f,t,s) can be transformed to the time delay-Doppler-angle dimension (target dimension) by performing an inverse Fourier transform along the frequency domain, a Fourier transform along the time domain, and a Fourier transform along the antenna domain.

[0199] The methods for determining the signal path (referred to as the sensing path) associated with the sensed target in the channel response obtained from the measurement of the target signal can include the following:

[0200] Determine the set of signal paths. The signal paths in the set include those whose amplitude, power, intensity, or energy exceeds a certain threshold after the channel response is transformed to the target dimension. For example, in Figure 4, signal paths 0, 1, 2, and 3 are paths in the signal path set; the certain threshold can be set to be higher than a noise threshold or a noise interference threshold, or as agreed upon by the protocol. This step (determining the set of signal paths) is optional; it can be based solely on the next step to determine the signal paths associated with the sensing target.

[0201] Signal paths that satisfy the target conditions are selected from the set of signal paths or from all signal paths of the target signal, and are used as the signal paths associated with the sensing target. The target conditions include at least one of the following:

[0202] The amplitude, power, strength, or energy of the signal path exceeds a preset threshold or falls within a preset range, such as a preset threshold that exceeds 5 times the noise threshold;

[0203] The Doppler signal path exceeds a preset threshold or falls within a preset range;

[0204] The delay of the signal path exceeds a preset threshold or falls within a preset range;

[0205] The angle of the signal path exceeds the preset threshold or is within the preset range;

[0206] The difference in amplitude / power / intensity / energy between the signal path and the first-reach path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range. The reference signal path can be a signal path reflected by a known target (e.g., RIS / Backscatter / other known passive targets, etc.).

[0207] The Doppler difference between the signal path and the first-reach path (e.g., the LOS path) or the reference path exceeds a preset threshold or falls within a preset range;

[0208] The time delay difference between the signal path and the first path (e.g., the LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0209] The angle difference between the diameter and the first-arrival diameter (e.g., the LOS diameter) or the reference diameter exceeds a preset threshold or falls within a preset range.

[0210] The amplitude, power, intensity, energy, or phase of the path satisfies a specific modulation rule, which is the modulation rule of the Tag / Backscatter device or RIS. That is, the path associated with the sensing target can be a signal path that has been modulated and reflected by the Tag / Backscatter device or RIS.

[0211] Among them, the above target conditions can also be based on the statistical results over a period of time; for example, the proportion of the above indicators (such as Doppler of the path, the time delay of the path, etc.) exceeding the preset threshold or falling within the preset range within the preset time window reaches the preset proportion, or the number of times the above indicators (such as Doppler of the path, the time delay of the path, etc.) exceed the preset threshold or fall within the preset range within the preset time window reaches the preset number.

[0212] The preset threshold or set range is sent to the receiving device by other devices, and determined by those devices based on prior sensing information or sensing requirements. Alternatively, the preset threshold or preset range can be agreed upon in a protocol, or it can be determined by the receiving device based on prior sensing information or sensing requirements.

[0213] Among them, prior information for perception or perception needs includes the following information:

[0214] Sensing services or types of sensing services, such as detecting the presence of a target, localization, velocity detection, distance detection, angle detection, acceleration detection, material analysis, composition analysis, shape detection, category classification, and radar cross section (RCS). The sensing services include: Section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, terrain and landform, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc. The sensing service types can be classified according to certain characteristics, such as by function (detection-type sensing services, including intrusion detection and fall detection), parameter estimation-type sensing services (distance, angle, and speed calculation), and recognition-type sensing services (action recognition, identity recognition), etc. They can also be classified by sensing range (near-range sensing, medium-range sensing, and long-range sensing), by sensing fineness (coarse-grained sensing, fine-grained sensing, etc.), by power consumption / energy consumption, and by resource usage, etc. If the sensing service is respiratory monitoring, the corresponding normal respiratory rate can be determined based on the person's gender and age (e.g., male: 13-21 breaths / minute, female: 15-20 breaths / minute; adult: 12-20 breaths / minute, child: approximately 30-40 breaths / minute), which can be used as prior information for sensing.

[0215] Perception target area: refers to the location area of ​​the perceived object, or the location area that needs to be imaged or reconstructed; for example, the preset range of the time delay of the perception target association path is determined based on the approximate location / distance of the perceived object.

[0216] Sensing object type: Sensing objects are classified according to their possible motion characteristics. Each sensing object type contains information such as the motion velocity range, motion acceleration range, and typical RCS range of typical sensing objects.

[0217] The number of perceived targets; for example, the number of perceived targets can be obtained from the camera's perception results as a priori information.

[0218] For example, in Figure 4, signal paths 0, 1, 2, and 3 are paths in the set of signal paths, where signal paths 2 and 3 are sensing paths that meet the target conditions (e.g., their time delay meets a preset threshold), and paths 0 and 1 are paths associated with other scatterers.

[0219] Figure 4 shows a schematic diagram of the channel response in the target dimension (time delay dimension, Doppler dimension, azimuth dimension, or elevation dimension), where the horizontal axis represents the target dimension and the vertical axis represents the normalized amplitude, power, intensity, or energy.

[0220] For frequency range 1, the reference point for the first indicator can be the antenna connector of the receiving device, such as the terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first indicator measured and reported by the receiving device cannot be lower than the indicator of any single receiving channel. For frequency range 2, the first indicator measured for a certain receiving channel needs to be obtained by measuring the combined signal on multiple antenna elements corresponding to that receiving channel.

[0221] Method 2 for calculating the first indicator:

[0222] When calculating the received power of the signal path associated with the perceived target, it can also be the power of the signal path associated with the perceived target in the target dimension and... The difference is used as the first indicator, where N1 represents the number of signal paths associated with the perceived target. The average power of multiple signal paths outside the set of signal paths in the target dimension.

[0223] Method 1 for calculating the received power of the target signal:

[0224] The received power of the target signal can be obtained by the receiving device after obtaining the channel response H(k), transforming it to the target dimension, determining the set of signal paths in the target dimension, and then calculating the sum of the power of all signal paths in the set of signal paths.

[0225] Method 2 for calculating the received power of the target signal:

[0226] The received power of the target signal can also be the sum of the power of all signal paths in the set of signal paths in the target dimension. The difference, where N2 represents the number of signal paths in the signal path set.

[0227] How to calculate total received power:

[0228] Total received power:

[0229] Where Y(k) is the received signal corresponding to the target signal, k = 0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units.

[0230] The calculation method for the second indicator:

[0231] The channel response H(k) is processed by the first filter to obtain H. filter1 (k), then according to H filter1 The received signal Y after the first filtering process is calculated from the target signal X(k) and the target signal X(k). filter1 (k), i.e., Y filter1 (k)=H filter1 (k)X(k). Then subtract the received signal Y(k) after the first filtering process from the received signal Y(k). filter1 (k) thus obtaining the interference and noise signal Y σ1 (k), i.e., Y σ1 (k)=Y(k)-Y filter1 (k), and then calculate the second index:

[0232] The first filtering process is used to eliminate noise and interference in the target dimension, as well as paths associated with non-perceptible targets. For example, the first filtering process sets the amplitude, power, intensity, or energy of paths other than those associated with perceptible targets in Figure 4 to zero. The channel response H after the first filtering process... filter1 (k) does not contain noise and interference, nor does it contain paths associated with non-perceived targets; it only contains paths associated with perceived targets.

[0233] The third indicator is calculated in the following way:

[0234] The channel response H(k) is processed by a second filter to obtain H. filter2 (k), then according to H filter2 The received signal Y after the second filtering process is calculated from the target signal X(k) and the target signal X(k). filter2 (k), i.e., Y filter2 (k)=H filter2 (k)X(k). Then subtract the received signal Y(k) after the second filtering process from the received signal Y(k). filter2 (k) thus obtaining the interference and noise signal Y σ2 (k), i.e., Y σ2 (k)=Y(k)-Y filter2 (k), and then calculate the third index:

[0235] The second filtering process described above can be noise interference suppression processing on the target dimension (e.g., setting the amplitude, power, intensity, or energy of other paths besides the signal path set in Figure 4 to zero), or minimum mean squared error (MMSE) filtering. The channel response H after the second filtering process... filter2(k) does not contain noise and interference, but only contains paths from the set of signal paths.

[0236] The third indicator is calculated in the second way:

[0237] Based on the average power of multiple signal paths outside the target dimension's signal path set The third index P was calculated. σ2 ,Right now Where N represents the number of sampling points in the target dimension.

[0238] It should be noted that if the receiving device identifies multiple sensing targets, or if the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, the following methods are available:

[0239] Method 1: Calculate the perception-related indicators (also called target indicators) for each sensing target separately. For example, in Figure 4, determine the signal path associated with each sensing target, and then calculate the perception-related indicators for each sensing target. When calculating the second indicator for a certain sensing target (such as sensing target A), there are two methods: namely, the second indicator of sensing target A = total received power - the first indicator of sensing target A; or, the second indicator of sensing target A = total received power - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets: A and B). Similarly, there are two ways to calculate the fourth indicator: the fourth indicator of sensing target A = the RSRP of the target signal - the first indicator of sensing target A; or, the fourth indicator of sensing target A = the RSRP of the target signal - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets: A and B).

[0240] Method 2: Calculate a perception-related index for multiple sensing targets. For example, in Figure 4, determine the signal paths associated with any sensing target, and then determine these signal paths as signal paths associated with the sensing target; this is equivalent to treating multiple sensing targets as a virtual sensing target, and then calculating the perception-related index corresponding to this virtual sensing target.

[0241] As an optional implementation, the first information satisfying a preset condition includes at least one of the following:

[0242] The perception-related indicators meet the preset indicator threshold requirements;

[0244] The device information of the first device includes at least one of the following: direction of movement, speed of movement, position information, or orientation information, which meets the preset device threshold requirements.

[0245] Among them, the aforementioned preset indicator threshold requirements, preset perception requirements, and preset device threshold requirements can be agreed upon by the protocol or configured on the network side, or determined by the aforementioned first device.

[0246] The above-mentioned perception-related indicators meeting the preset threshold requirements can mean that the perception-related indicators reach the preset threshold, or that the perception-related indicators are within the preset threshold range.

[0247] The above-mentioned sensing measurement results satisfying the preset sensing requirements can be that the sensing measurement results indicate whether a sensing target or a signal path associated with the sensing target is detected, or the sensing measurement results (such as time delay, Doppler, angle, etc.) are within the preset sensing threshold range, or the target position coordinates calculated based on the sensing measurement results are within the preset position range.

[0248] The device information of the first device mentioned above, including at least one of the following: direction of motion, speed of motion, position information, or orientation information, must satisfy a preset device threshold requirement:

[0249] The equipment information of the first device includes a movement direction that matches a preset direction, or a movement direction that is within a preset orientation range;

[0250] The speed of the first device exceeds a preset speed threshold, or the speed of the first device is within the preset speed threshold range;

[0251] The location information of the first device is within the preset location range;

[0252] The orientation information of the first device matches the preset direction, or the angle between the orientation of the device and the direction of the area where the sensing target is located is less than the preset threshold.

[0253] In one of the above optional implementations, it is possible to determine whether to perform perception measurement behavior based on multiple dimensions to meet more perception-oriented business needs and improve the compatibility of perception measurement.

[0254] In some implementations, the first information further includes communication-related metrics, wherein the communication-related metrics may include at least one of the following:

[0255] Reference Signal Received Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Received Quality (RSRQ), Channel Quality Indicator (CQI), Signal to Interference plus Noise Ratio (SINR), and Signal to Noise Ratio (SNR).

[0256] The aforementioned first information meeting the preset conditions also includes communication-related indicators meeting preset communication requirements, such as communication-related indicators reaching preset thresholds, or communication-related indicators being within preset threshold ranges.

[0257] This allows for the execution of sensing and measurement actions while ensuring that communication-related indicators meet preset communication requirements. For example, sensing and measurement actions can be performed when communication-related indicators indicate a favorable communication condition, thereby further improving the reliability of sensing and measurement actions.

[0258] As an optional implementation, the above method further includes:

[0259] The first device receives second information, the second information including at least one of the following:

[0260] The relevant information of the preset conditions, the configuration information of the first signal, the configuration information of the second signal, the measurement configuration information, the perception requirement information, and the perception prior information;

[0261] The second signal is a sensing signal sent by the first device.

[0262] The aforementioned second information may be second information received by the first device from the second device.

[0263] The relevant information of the aforementioned preset conditions may be information used to determine the aforementioned preset conditions, such as the relevant information of the aforementioned preset conditions may include at least one of the following:

[0264] The indication information of the perception-related indicators, the threshold information related to the perception-related indicators, the requirement information of the perception measurement results, and the requirement information of the device information.

[0265] The aforementioned perception-related indicator information is used to indicate the perception-related indicators in the first information, that is, to indicate the perception-related indicators used to determine whether to perform perception measurement behavior, such as indicating at least one of the first to eighth indicators in the above embodiment as the perception-related indicators used to determine whether to perform perception measurement behavior.

[0266] Since the second information includes information related to the preset conditions, the first device determines the preset conditions based on this information, thereby making the first device and the device that sent the second information have a consistent understanding of the sensing and measurement behavior, thus improving the sensing and measurement performance between the devices.

[0267] The configuration information of the first signal or the configuration information of the second signal may include at least one of the following:

[0268] Signal configuration identifier (ID) is used to distinguish different signal configurations;

[0269] The time-domain resource length T, also known as the burst duration, is inversely proportional to the Doppler resolution.

[0270] The time-domain resource interval ΔT refers to the time interval between two adjacent signal resource units. The time-domain resource interval is related to the maximum unambiguous Doppler frequency or the maximum unambiguous velocity.

[0271] The frequency domain resource length B, i.e. the frequency domain bandwidth, is inversely proportional to the distance resolution. The frequency domain bandwidth B of each first signal or second signal is greater than or equal to c / (2ΔR), where c is the speed of light and ΔR is the distance resolution.

[0272] Frequency domain resource spacing ΔF is inversely proportional to the maximum unambiguous distance / delay. For OFDM systems, when subcarriers are continuously mapped, the frequency domain spacing is equal to the subcarrier spacing.

[0273] Signal direction, the angle or beam information of the signal transmission, or the spatial filtering parameters of the transmission.

[0274] The configuration information of the first signal enables the first device to measure the first signal more accurately, thereby improving the sensing and measurement performance. The configuration information of the second signal enables the first device to send the second signal more accurately, and the second signal is used for sensing, thereby improving the sensing and measurement performance.

[0286] The aforementioned sensing requirement information represents the sensing requirement information corresponding to the aforementioned sensing measurement behavior, and the aforementioned sensing prior information can be used to assist the first device in performing the aforementioned sensing measurement behavior. Thus, the sensing performance of the first device can be improved through the aforementioned sensing requirement information or sensing prior information.

[0287] In some implementations, the aforementioned perceived demand information may include at least one of the following:

Perception services can be categorized into several types: detection-based (e.g., intrusion detection, fall detection), parameter estimation-based (distance, angle, speed calculation), and recognition-based (action recognition, identity recognition); or target detection and tracking-based (e.g., target presence detection, target ranging / angle measurement / positioning / trajectory tracking), environmental monitoring-based (e.g., rainfall detection, flood monitoring), and action detection-based (e.g., gesture / action recognition, breathing / heartbeat detection, fall detection). They can also be categorized by perception range (near-range, medium-range, long-range), perception fineness (coarse-grained, fine-grained), perception scenario (indoor, outdoor, home, factory, highway, etc.), power consumption / energy consumption, and resource usage.

[0289] The target area for perception can refer to the area where the object being perceived may exist, or the area where imaging or environmental reconstruction is required.

[0290] The sensing object type can be a classification of sensing objects based on their possible motion characteristics. Each sensing object type contains information such as the motion velocity, motion acceleration, and typical RCS of typical sensing objects.

[0291] Sensing QoS can be a performance indicator for sensing target areas or objects, including at least one of the following:

[0292] Perception resolution can be categorized into: ranging resolution, angle measurement resolution, velocity measurement resolution, and imaging resolution, etc.

[0300] Optionally, the relevant information of the preset conditions is associated with the perception requirement information or the perception prior information;

[0301] or,

[0302] The configuration information of the first signal is associated with the sensing requirement information or the sensing prior information;

[0303] or,

[0304] The configuration information of the second signal is associated with the perception requirement information or the perception prior information.

[0305] The association between the relevant information of the aforementioned preset conditions and the perception requirement information or the perception prior information can be understood as the relevant information of the preset conditions being determined based on at least one of the perception requirement information or the perception prior information.

[0306] The association between the configuration information of the first signal and the perception requirement information or the perception prior information can be understood as the configuration information of the first signal being determined based on at least one of the perception requirement information or the perception prior information.

[0307] The association between the configuration information of the second signal and the perception requirement information or the perception prior information can be understood as the fact that the configuration information of the second signal can be determined based on at least one of the perception requirement information or the perception prior information.

[0308] In some implementations, various preset conditions or signal configuration information can be pre-configured or agreed upon by protocol. The first device is based on the aforementioned sensing requirement information or sensing prior information, corresponding to the preset conditions or signal configuration information. For example, the sensing type in the sensing requirement or sensing prior information is associated with the detection range corresponding to the measured quantity, and it can also be associated with different signal configurations, such as the configuration information of several different signals predefined by the protocol, or the configuration information of several different signals pre-configured through higher-layer signaling. In this way, the configuration information of the first signal or the second signal can be determined through the sensing requirement or sensing prior information.

[0309] Assuming that each parameter in the configuration information of the first or second signal has two configurations, with the time-domain resource length T1, time-domain resource interval ΔT1, frequency-domain resource length B1, and frequency-domain resource interval ΔF1 being smaller, and the time-domain resource length T2, time-domain resource interval ΔT2, and frequency-domain resource length B2, and frequency-domain resource interval ΔF2 being larger, one association method can be shown in Table 2:

[0310] Table 2:

[0311] Thus, Table 2 above allows us to perceive the measured quantity and detection range in the measurement results, as well as determine the configuration information of the first or second signal. Table 2 is merely an example.

[0312] Since the information related to the preset conditions is associated with the perception requirement information or the perception prior information, the perception measurement behavior performed based on the preset conditions can be better matched with the perception service, thereby improving perception performance.

[0313] Since the configuration information of the first signal is associated with the perception requirement information or the perception prior information, the first signal can be better matched with the perception service, thereby improving the perception performance.

[0314] Since the configuration information of the second signal is associated with the perception requirement information or the perception prior information, the second signal can be better matched with the perception service, thereby improving the perception performance.

[0315] In some implementations, the configuration information of the first signal or the second signal may further include at least one of the following:

[0316] The purpose of the signal indicates whether the target signal is used for communication (e.g., channel measurement, channel estimation, synchronization, carrying data information, etc.), for sensing, or for both communication and sensing. Specifically, it can also specify which sensing service the signal is used for, or which type of sensing service it is used for.

[0318] Waveforms can be OFDM, Single-carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), or pulse signals, etc.

[0319] Subcarrier spacing, which can be the subcarrier spacing of an OFDM system, for example: 30KHz.

[0320] The guard interval can be the time interval from the end of signal transmission to the moment when the latest echo of the signal is received. This parameter is proportional to the maximum sensing distance; for example, it can be expressed as c / (2R). max )Calculations show that R max For the maximum sensing distance (belonging to sensing demand information), such as for spontaneously generated and received sensing signals, R max This represents the maximum distance from the signal transmission / reception point to the signal reflection point; in some cases, the OFDM signal cyclic prefix (CP) can serve as a minimum guard interval, where c is the speed of light.

[0321] The starting position in the frequency domain can be the starting frequency point, or it can be the index of the starting resource element (RE) or resource block (RB).

[0322] The frequency domain start position and the time domain start position can be the start time point, or the start symbol, time slot, or frame index.

[0323] Time-domain resource characteristics can be periodic transmission, semi-persistent transmission, or aperiodic transmission.

[0324] Signal power can be an interval power value, for example: a value is taken every 2dBm from -20dBm to 23dBm.

[0325] Sequence information can include sequence type information (such as ZC sequence, PN sequence, etc.), sequence generation method, or sequence length.

[0326] Quasi-co-location (QCL) relationships can represent that the above signals include multiple resources, each resource is associated with a synchronization signal block (SSB) QCL, and QCLs include type A, type B, type C, or type D.

[0327] Antenna port information, which can be the maximum number of antenna ports or the antenna port index.

[0328] Cyclic Prefix (CP) information can include CP type or CP length, etc. The CP type can include normal cyclic prefix (NCP), extended cyclic prefix (ECP), or newly designed sensing measurement-specific CP, etc.

[0329] The configuration information of the first or second signal mentioned above may be the same or different for different types of sensing targets.

[0330] In some implementations, the configuration information of the first signal or the second signal may include one or more of the following: it may be agreed upon by the protocol or pre-configured, and there is no limitation on this.

[0331] In some implementations, at least one of the aforementioned second information may also be a protocol agreement or a network-side configuration, and there is no limitation on this.

[0332] As an optional implementation, the method further includes:

[0340] The aforementioned third information not meeting the preset condition may be that all of the third information obtained consecutively does not meet the preset condition, or it may be that any one of the third information does not meet the preset condition.
