[0045] In addition, the embodiments of the present application can be applied to the communication and perception integration scenario, where communication and perception integration refers to the integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system. While transmitting information, the system can perceive information such as direction, distance, speed, and detect, track, and identify target devices or events.

[0047] In the embodiment of the present application, depending on the difference between the sending node and the receiving node of the perception signal, the six types of perception links shown in Figure 2 may be included but not limited to. It should be noted that each perception link in Figure 2 is illustrated by taking a sending node and a receiving node as an example. In the actual system, different perception links can be selected according to different perception needs. Each perception link may have one or more sending nodes and one receiving node, and the actual perception system may include a variety of different perception links. In addition, the perception targets in Figure 2 take people and cars as examples, and assuming that people and cars do not carry or install signal receiving / transmitting equipment, the perception targets of the actual scene will be richer.

[0054] In some embodiments, the signaling transmission between the wireless access network device and the terminal, or between different terminals, may be through Radio Resource Control (RRC) signaling or Medium Access Control Control Element (MAC CE) or Layer 1 signaling or other newly defined perception signaling; the signaling transmission between the perception network function and the terminal may be through Non-Access-Stratum (NAS) signaling (forwarded via AMF) or through RRC signaling or MAC CE or Layer 1 signaling or other newly defined perception signaling; the interaction between the perception network function and the base station may be forwarded to the wireless access network through the N2 interface by the AMF; or the core network perception network function may send it to the UPF, and the UPF may send it to the wireless access network through the N3 interface; or it may be sent to the wireless access network (such as a base station) through a newly defined interface; the signaling transmission between wireless access network devices may be through the Xn interface.

[0055] In some embodiments, the perception network function may also be called a perception network element or a perception management function (Sensing Management Function, Sensing MF), which may be located on the RAN side or the core network side. It refers to a network node in the core network or RAN responsible for at least one function such as perception request processing, perception resource scheduling, perception information interaction, and perception data processing. It may be based on an upgrade of the AMF or LMF in the mobile communication network, or it may be another network node or a newly defined network node. Specifically, the functional characteristics of the perception network function / perception network element may include at least one of the following:

[0056] Target information is exchanged with a wireless signal sending device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area), wherein the target information includes a perception processing request, a perception capability, perception assistance data, a perception measurement quantity type, a perception resource configuration information, etc., to obtain the value of the target perception result or the perception measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal can also be referred to as a perception signal.

[0057] The perception method to be used is determined based on factors such as the type of perception service, perception service consumer information, required perception service quality (QoS) requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception method may include: wireless access network device A sends and wireless access network device B receives, or the wireless access network device sends and the terminal receives, or the wireless access network device A sends and receives by itself, or the terminal sends and the wireless access network device receives, or the terminal sends and receives by itself, or terminal A sends and terminal B receives, etc.

[0058] The perception device serving the perception service is determined based on factors such as the type of perception service, information about the perception service consumer, required perception QoS requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device.

[0060] The sensory measurement values ​​are processed or calculated to obtain sensory results. Furthermore, the sensory results are verified and the sensory accuracy is estimated.

[0061] In the following, in conjunction with the accompanying drawings, a measurement configuration information sending method, receiving method, apparatus and device provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0062] Please refer to FIG3 , which is a flowchart of a method for sending measurement configuration information provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0063] Step 301: A first device obtains event information, where the event information indicates that a measurement switching trigger event is satisfied, and the measurement switching trigger event includes that a perception-related indicator associated with a first signal satisfies a switching condition.

[0064] The first device may be a terminal, a wireless access network device or a core network element.

[0065] The first device acquiring the event information may be that the first device receives event information sent by other devices, such as the first device receives event information sent by a receiving device of the first signal, or the first device obtains the event information through measurement.

[0066] For example, the event information obtained by the first device includes the following:

[0067] The first device measures the first signal to obtain the event information;

[0068] The first device receives the event information.

[0069] The first signal may be a signal sent by the first device and sent and received by the first device itself, or the first device may send the first signal, the second device may measure the first signal, and feed back the event information to the first device.

[0070] Alternatively, the first signal is sent by another device, and the first device measures the first signal to obtain event information.

[0071] In an embodiment of the present application, the above-mentioned first signal may be a dedicated signal for sensing services, or a communication signal, such as a reference signal or a synchronization signal.

[0072] The dedicated signal for the sensing service may be a sensing signal generated based on a chirp or frequency modulated continuous wave (FMCW) signal, or a sensing signal generated based on a pseudo-random (PN) sequence or a ZC sequence.

[0073] The reference signal may 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).

[0074] The synchronization signal may be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS).

[0075] The above-mentioned signal carrying communication data can be a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical downlink control channel (PDCCH) or a physical uplink control channel (PUCCH), etc.

[0076] The above-mentioned measurement switching triggering event indicates that the event is used to trigger measurement switching, such as perception switching (or perception measurement switching).

[0077] The perception-related indicator associated with the first signal may be a perception-related indicator obtained through a measurement process based on the first signal, or may be a perception-related indicator obtained during the process of receiving the first signal.

[0078] The above-mentioned perception-related indicators refer to perception-related indicators, such as indicators that affect perception targets or indicators that affect perception measurements.

[0079] The above-mentioned indicators meeting the switching conditions may be determined by the protocol, network-side equipment, or by the device generating the above-mentioned event information. For example, the perception-related indicators may reach a preset threshold, such as the perception-related indicators being less than the preset threshold, or being within the preset threshold range, or the perception-related indicators indicating deterioration in perception performance, or the perception-related indicators indicating an inability to meet perception requirements. Alternatively, the above-mentioned switching conditions may be met by the perception-related indicators measured multiple times in a row.

[0080] Since the measurement switching trigger event includes that the perception-related indicator associated with the first signal meets the switching condition, it is possible to trigger the switching measurement when the perception-related indicator associated with the first signal meets the switching condition, thereby improving measurement performance.

[0081] Step 302: The first device sends handover measurement configuration information to the second device.

[0082] Specifically, step 302 is that upon receiving the above event information (ie, satisfying the measurement switching trigger event), the first device sends switching measurement configuration information to the second device, or in response to the above event information, the first device sends switching measurement configuration information to the second device.

[0083] The handover measurement configuration information is used to configure handover measurements, such as configuration of measurement objects, configuration of measurement identifiers, configuration of measurement contents, and other information. Handover measurements refer to measurements performed for measurement handover to trigger measurement handover, such as sensory handover. Thus, the handover measurement configuration information can trigger measurement handover, such as sensory handover.

[0084] In some implementations, the handover measurement configuration information may also be used to indicate measurement handover, such as indicating perception handover, or a command indicating measurement handover, such as a handover command for perception handover, may be sent after sending the handover measurement configuration information.

[0085] In the embodiment of the present application, the above steps can realize the transmission of handover measurement configuration information between devices when a measurement handover triggering event is met, so that the devices support handover measurement, thereby improving the perception measurement performance of the devices.

[0086] In an embodiment of the present application, the measurement switching can be a perception switching, so that the device can support perception switching, thereby ensuring the continuity of perception services for mobile targets and improving the perception switching performance, such as switching of perception links due to changes in the mobility of the perception target or perception device or other environmental conditions.

[0087] In some implementations, the second device performs a handover measurement behavior after receiving the handover measurement configuration information.

[0088] The performing of the handover measurement behavior may include at least one of the following:

[0089] performing a switching measurement based on the second signal;

[0090] performing a switching measurement based on a third signal;

[0091] sending a fourth signal, where the fourth signal is a measurement signal for switching measurement;

[0092] The second signal is sent by the same device as the first signal, and the second signal may be the same as or different from the first signal.

[0093] The third signal is a signal sent by the second device and measured by the second device, that is, a signal sent and received by the second device itself.

[0094] The fourth signal is a signal sent by the second device. The fourth signal may be measured by the device sending the first signal or by the first device.

[0095] In the above implementation, multiple handover measurements are supported to improve the flexibility of handover measurements.

[0096] As an optional implementation manner, the perception-related indicator includes at least one of the following:

[0097] Perception indicators related to received power;

[0098] Perceptual metrics related to interference or noise power;

[0099] A perceptual metric related to received power, and also to interference or noise power.

[0100] The above-mentioned received power-related perception indicators may include at least one of the following:

[0101] A perception indicator related to the received power of the first signal and a perception indicator related to the received power of a signal path of the first signal associated with a perception target. For example, the perception indicator related to received power may include: a first indicator, the first indicator being used to indicate the received power of the signal path of the first signal associated with the perception target.

[0102] The signal path associated with the aforementioned perception target may be a signal path affected by the perception target or a signal path passing through the perception target.

[0103] In one of the above optional embodiments, since the perception-related indicators include perception indicators related to received power, measurement switching can be triggered based on received power, making measurement switching more reliable. Additionally, measurement switching can be triggered 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 can more intuitively reflect whether measurement switching is necessary. Therefore, using the above first indicator can make measurement switching more reliable.

[0104] In some embodiments, the first indicator may be a linear average value (in W) of the received power of the signal path associated with the perception target in the channel response obtained by measuring the first signal on the resource unit carrying the first signal, and the resource unit is a time domain or frequency domain resource unit. In this way, the received power can be made more accurate and reliable through the linear average value. It should be noted that the embodiments of the present application do not limit the received power to a linear average value. For example, in some embodiments, the median received power, the minimum received power, or the maximum received power may also be taken.

[0105] The above-mentioned perception indicator related to interference or noise power may refer to the perception indicator being associated with at least one of interference and noise, such as a perception indicator associated with interference power, a perception indicator associated with noise power, or an interference indicator associated with both interference and noise power.

[0106] In the above optional implementation manner, since the perception-related indicators include perception indicators related to interference or noise power, it is possible to take interference or noise into consideration when determining measurement switching, thereby making the measurement switching more reliable.

[0107] Optionally, the perception indicator related to the interference or noise power includes at least one of the following:

[0108] a second indicator, where the second indicator is the sum of a linear average of the powers of 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 a linear average of the interference or noise power from 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, where the total received power is the total received power of the first device on the target resource;

[0109] a third indicator, where the third indicator is a linear average of interference or noise power from signals other than the first signal on the second resource, or the third indicator is equal to a difference between a total received power and a received power of the first signal, where the total received power is the total received power of the first device on the target resource;

[0110] a fourth indicator, the fourth indicator being a linear average of the powers of signal paths other than the signal path associated with the perception target in the channel response of the first signal on the target resource; or, the fourth indicator being equal to the difference between the received power of the first signal and the first indicator;

[0111] Among them, the first indicator is used to indicate the receiving power of the signal path of the first signal associated with the perception target, 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.

[0112] The above-mentioned other signal paths may be all or part of the signal paths in the first signal except the signal paths associated with the above-mentioned perception target.

[0113] The other signals other than the above-mentioned first signal may refer to all or part of the signals other than the first signal detected by the first device on the first resource.

[0114] The first resource includes the target resource or at least one resource other than the target resource, which means that the first resource includes at least one of the following:

[0115] a target resource, and at least one resource other than the target resource.

[0116] The second resource includes the target resource or at least one resource other than the target resource, which means that the second resource includes at least one of the following:

[0117] a target resource, and at least one resource other than the target resource.

[0118] Among them, the above-mentioned at least one resource other than the target resource may refer to at least one resource other than the target resource among the resources that the first device needs to detect or receive signals, such as resources configured by high-level signaling or resources that the first device predetermines need to detect or receive signals.

[0119] The above-mentioned interference or noise power includes the sum of interference power and noise power, interference power or noise power.

[0120] The total received power of the first device on the target resource may include the received power of signals of the serving cell and the non-serving cell on the target resource, adjacent channel interference power, and thermal noise power. The total received power may also be a linear average (in W) of the total received power of the first device on the target resource.

[0121] The power corresponding to the received signal strength indication (RSSI) of the first device on the first resource may be total received power = RSSI * K1, where K1 is a coefficient and may be a protocol agreement or network-side configuration. In some embodiments, the power corresponding to the RSSI may also be RSSI, i.e., total received power = RSSI.

[0122] The received power of the first signal refers to the reference signal received power (RSRP) of the first signal.

[0123] The above-mentioned second indicator 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.

[0124] The third indicator equal to the difference between the total received power and the received power of the first signal can be expressed as third indicator = total received power - first signal received power.

[0125] The fourth indicator equal to the difference between the received power of the first signal and the first indicator can be expressed as fourth indicator=received power of the first signal-first indicator.

[0126] In the above embodiment, the second indicator can be used to consider interference or noise of other signal paths other than the signal path associated with the perception target and other signals other than the first signal when determining measurement switching, which can make measurement switching more reliable.

[0127] In the above implementation, the third indicator can be used to consider interference or noise of other signals besides the first signal when determining measurement switching, which can make the measurement switching more reliable.

[0128] In the above implementation, the fourth indicator can be used to consider the power of other signal paths except the signal path associated with the sensing target when determining the measurement switching, which can make the measurement switching more reliable.

[0129] The above-mentioned perception indicator related to the received power and also related to the interference or noise power means that the perception indicator is related to both the received power and the interference or noise power.

[0130] In the above optional implementation, since the perception-related indicators include perception indicators related to the received power and also related to the interference or noise power, it is possible to take the received power and the interference or noise into consideration when determining the measurement switch, so that the measurement switch is more reliable.

[0131] In some embodiments, the perception indicator related to received power and also related to interference or noise power includes at least one of the following:

[0132] a fifth index, the fifth index being equal to a quotient obtained by dividing the first index by the second index;

[0133] a sixth index, the sixth index being equal to a quotient obtained by dividing the first index by the third index;

[0134] a seventh index, the seventh index being equal to a quotient obtained by dividing the first index by the fourth index;

[0135] an eighth indicator, the eighth indicator being equal to the product of a quotient obtained by dividing the first indicator by the total received power and a target coefficient;

[0136] The first indicator is used to indicate the received power of the signal path of the first signal associated with the perception target, and the total received power is the total received power of the first device on the target resource.

[0137] The first, second, third, and fourth indicators mentioned above refer to the above-mentioned embodiments and are not described in detail 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 the present application may include or exclude the first, second, third, and fourth indicators.

[0138] The above target coefficient can be expressed as K2, such as the eighth indicator = K2*first indicator / total received power, K2 is a coefficient, and K2 can be specifically agreed upon in the protocol or configured on the network side.

[0139] In this implementation, by using the fifth indicator, the sixth indicator, the seventh indicator or the eighth indicator, it is possible to take the received power and the interference or noise into consideration when determining the measurement switching, so that the measurement switching is more reliable.

[0140] In some implementations, the aforementioned perception indicator related to received power and also related to interference or noise power may further include at least one of the following:

[0141] Indicators related to perceived SINR, indicators related to perceived SNR, indicators related to perceived signal-to-interference ratio (SIR), and indicators related to perceived RSRQ.

[0142] As an optional implementation manner, the signal path associated with the perception target satisfies at least one of the following:

[0143] The parameter meets the first preset threshold, or the parameter is within the first preset range;

[0144] The parameters meet the preset modulation rules;

[0145] The parameter difference with the first signal path meets the second preset threshold, or the parameter difference with the first signal path is within the second preset range;

[0146] The parameter difference with the reference signal path meets the third preset threshold, or the parameter difference with the reference signal path is within a third preset interval.

[0147] The above parameters may include at least one of the following:

[0148] Amplitude, power, intensity, energy, phase, Doppler, delay, angle;

[0149] The above parameter difference may include at least one of the following:

[0150] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, delay difference, and angle difference.

[0151] 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 may be agreed upon by the protocol or configured on the network side, or these preset thresholds or preset interval ranges are determined by the receiving device based on the perception prior information or perception requirements. The above-mentioned parameter meeting the first preset threshold may mean that the parameter exceeds or is equal to the first preset threshold, the above-mentioned parameter difference with the first-reaching signal path meets the second preset threshold may mean that the parameter difference with the first-reaching signal path exceeds or is equal to the second preset threshold, and the above-mentioned parameter difference with the reference signal path meets the third preset threshold may mean that the parameter difference with the reference signal path exceeds or is equal to the third preset threshold.

[0152] For example: if the perception service is moving target detection, it is necessary to detect the signal path with Doppler greater than zero as the signal path associated with the perception target; or for the traffic scene where the perception target is a car, the default vehicle speed is 40km / h to 120km / h, then the signal path within the corresponding speed range (Doppler range) is detected as the signal path associated with the perception target; or the distance between the perception target area and the perception signal transceiver needs to meet specific requirements, then the signal path within the corresponding time delay range is detected as the signal path associated with the perception target; or if the perception service is respiratory monitoring, the corresponding normal respiratory rate can be judged based on the person's gender and age (for example, 15 to 30 times / minute can be used as perception prior information, and the corresponding Doppler range can be calculated, 0.25 to 0.5Hz).

[0153] The first-arrival signal path may be a line-of-sight (LOS) path, specifically, the signal path of the first signal that first reaches the receiver. The reference signal path may be a signal path reflected by a known target, such as a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.

[0154] The preset modulation rule may be a protocol agreement or a network-side configuration. The specific modulation rule is a modulation rule of a tag, backscatter device, or RIS, that is, the signal path associated with the sensing target may be a signal path modulated and reflected by the tag, backscatter device, or RIS.

[0155] In one of the above optional implementations, the signal path associated with the perception target can be determined in multiple ways, which can not only improve the flexibility of determining the signal path associated with the perception target, but also improve the accuracy of determining the signal path associated with the perception target based on multiple methods.

[0156] In some implementations, before determining the signal path associated with the perceived target, a signal path set may be determined. The signal path set includes signal paths whose amplitude, power, intensity, or energy exceeds a certain threshold. As shown in FIG4 , the signal path set includes signal paths 0, 1, 2, and 3. The signal path associated with the perceived target is then determined based on at least one of the above items in the signal path set to reduce computational complexity.

[0157] The following example illustrates the calculation of indicators in the embodiment of the present application through an example. It should be noted that the calculation of each indicator in the embodiment of the present application is not limited, and the following example is only an example.

[0158] The first device (such as a terminal) performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain a channel response (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 the first device obtains the channel response H(k), it transforms it into a first dimension and determines the signal path associated with the perception target in the first dimension. The power of the signal path associated with the perception target is then calculated as the first indicator. If the signal path associated with the perception target includes multiple signal paths, the sum of the powers of the multiple signal paths is calculated as the first indicator.

[0159] The first dimension includes one of the following:

[0160] Delay dimension;

[0161] Doplevi;

[0162] Azimuth dimension;

[0163] Pitch angle dimension;

[0164] A dimension that combines at least two of the following: delay, Doppler, azimuth, and elevation dimensions. For example, delay-Doppler, delay-Doppler-angle, etc.

[0165] For example, H(f) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and H(f) can be transformed into the delay dimension (first dimension) by performing an inverse Fourier transform on it. For another example, H(f, t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., OFDM symbol index), and H(f, t) can be transformed into the time domain dimension by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension. Delay-Doppler dimension (first dimension); for another example, H(f,t,s) 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 into the delay-Doppler-angle dimension (first dimension) by performing an inverse Fourier transform along the frequency domain dimension, a Fourier transform along the time domain dimension, and a Fourier transform along the antenna domain dimension.

[0166] Method for determining a signal path associated with a perception target (referred to as a perception path for short) in a channel response obtained by measuring the first signal:

[0167] Determine the signal path set. The signal paths in the signal path set include those whose amplitude, power, intensity, or energy exceeds a certain threshold among all paths after the channel response is transformed into the first dimension. For example, in Figure 4, signal paths 0, 1, 2, and 3 are the paths in the signal path set; the certain threshold can be set to be higher than the noise threshold or higher than the noise interference threshold, or as agreed upon by the protocol. This step (determining the signal path set) is optional, and the signal path associated with the perception target can be determined based on the next step.

[0168] A signal path that satisfies a first condition is selected from the signal path set or from all signal paths of the first signal as the signal path associated with the sensing target. The first condition includes at least one of the following:

[0169] The amplitude, power, intensity or energy of the signal path exceeds a preset threshold or is within a preset range, such as 5 times the noise threshold;

[0170] The Doppler of the signal path exceeds the preset threshold or is within the preset range;

[0171] The signal path delay exceeds the preset threshold or is within the preset range;

[0172] The angle of the signal path exceeds the preset threshold or is within the preset range;

[0173] The difference in amplitude / power / intensity / energy between the signal path and the first-reach path (e.g., LOS path) or a reference path exceeds a preset threshold or is within a preset range. The reference signal path may be a signal path reflected by a known target (e.g., RIS / backscatter / other known passive targets).

[0174] The Doppler difference between the signal path and the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0175] The delay difference between the signal path and the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0176] The angle difference between the path and the first arrival path (such as LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0177] The amplitude, power, intensity, energy or phase of the path meets the specific modulation rule. The specific modulation rule is the modulation rule of the tag / backscatter device or RIS. That is, the path associated with the perceived target can be the signal path modulated and reflected by the tag / backscatter device or RIS.

[0178] The above-mentioned first conditions may also be based on statistical results over a period of time; for example, the ratio of the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding a preset threshold or being within a preset range in a preset time window reaches a preset ratio, or the number of times the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed a preset threshold or are within a preset range in a preset time window reaches a preset number of times;

[0179] The preset threshold or preset interval is sent by another device to the receiving device and is determined by the other device based on prior perception information or perception requirements. Alternatively, the preset threshold or preset interval may be a protocol agreement, or the preset threshold or preset interval is determined by the receiving device based on prior perception information or perception requirements.

[0180] The priori perception information or perception requirements include the following information:

[0181] Perception services or perception service types, such as detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section RCS (Radar Cross Section, RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, population statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type can be to classify multiple different perception services according to certain characteristics, for example, according to function, it can be divided into detection-type perception services (for example, including intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (motion recognition, identity recognition), etc., and can also be divided according to the range of perception (close-range perception, medium-range perception, long-range perception), according to the degree of perception fineness (coarse-grained perception, fine force perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the sensing service is respiratory monitoring, the corresponding normal respiratory rate can be determined based on the person's gender and age (for example, 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 perception prior information;

[0182] Perception target area: refers to the location area of ​​the perception object, or the location area where imaging or environmental reconstruction is required; for example, the preset interval range of the delay of the signal path associated with the perception target is determined based on the approximate location / distance of the perception object;

[0183] Perception object type: Classifies the perception object according to its possible motion characteristics. Each perception object type contains information such as the typical perception object's motion speed range, motion acceleration range, and typical RCS range.

[0184] The number of perceived targets; for example, the camera perception result is used as a perception prior information to obtain the number of perceived targets.

[0185] For example, in Figure 4, signal paths 0, 1, 2, and 3 are paths in the signal path set, among which signal paths 2 and 3 are perception paths that meet the first condition (for example, their delays meet the preset threshold), and paths 0 and 1 are paths associated with other scatterers.

[0186] In Figure 4, the channel response is a schematic diagram of multiple signal paths in the first dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation angle dimension), where the horizontal axis is the first dimension and the vertical axis is the normalized amplitude, power, intensity or energy.

[0187] For frequency range 1, the reference point for the first metric can be the antenna connector of a receiving device, such as a terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first metric measured and reported by the receiving device cannot be lower than the metric of any single receiving channel. For frequency range 2, the first metric measured for a particular receiving channel requires measuring the combined signals of the multiple antenna elements corresponding to that receiving channel.

[0188] Calculation method 2 of the first indicator:

[0189] When calculating the received power of the signal path associated with the sensing target, it can also be the power of the signal path associated with the sensing target in the first dimension and The difference between is used as the first indicator, where N1 represents the number of signal paths associated with the perception target. is the average power of multiple signal paths outside the signal path set in the first dimension.

[0190] The calculation method of the received power of the first signal is:

[0191] The receiving power of the first signal may be obtained by the receiving device, transforming the channel response (Channel Response) H(k) into the first dimension, determining a signal path set in the first dimension, and then calculating the power sum of all signal paths in the signal path set.

[0192] Method 2 for calculating the received power of the first signal:

[0193] The received power of the first signal can also be the sum of the powers of all signal paths in the signal path set in the first dimension and , where N2 represents the number of signal paths in the signal path set.

[0194] The total received power is calculated as follows:

[0195] Total received power

[0196] Wherein, Y(k) is the received signal corresponding to the first signal, k=0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units.

[0197] The calculation method of the second indicator is:

[0198] The channel response H(k) is processed by the first filter to obtain H filter1 (k), then according to H filter1 (k) and the first signal X(k) to obtain the received signal Y after the first filtering process filter1 (k), that is, Y filter1 (k)=H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the first filtering process. filter1 (k) Thus we get the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate the second indicator:

[0199] The first filtering process is used to eliminate noise and interference in the first dimension and paths not associated with the perceived target. For example, the first filtering process sets the amplitude, power, intensity or energy of all paths other than the signal path associated with the perceived target in FIG4 to zero. The channel response H after the first filtering process is filter1 (k) does not include noise, interference, or paths associated with non-perceived targets, but only includes paths associated with perceived targets.

[0200] Calculation method of the third indicator:

[0201] The channel response H(k) is processed by the second filter to obtain H filter2 (k), then according to H filter2 (k) and the first signal X(k) to obtain the second filtered received signal Y filter2 (k), that is, Y filter2 (k)=H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the second filtering process. filter2 (k) Thus we get the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then calculate the third indicator:

[0202] The second filtering process can be a noise interference suppression process in the first dimension (for example, the amplitude, power, intensity or energy of the paths other than the signal path set in FIG4 is set to zero), or a minimum mean square error (MMSE) filter. The channel response H after the second filtering process is filter2 (k) does not include noise and interference, and only includes the paths in the signal path set.

[0203] Calculation method 2 for the third indicator:

[0204] According to the average power of multiple signal paths outside the signal path set in the first dimension Calculate the third index P σ2 ,Right now Where N represents the number of sampling points in the first dimension.

[0205] It should be noted that if the receiving device determines that there are multiple sensing targets, or the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, the following methods are available:

[0206] Method 1: Calculate the perception-related indicators (also called target indicators) of each perception target separately. For example, in Figure 4, the signal path associated with each perception target is determined separately, and then the perception-related indicators corresponding to each perception target are calculated separately; when calculating the second indicator corresponding to a certain perception target (such as perception target A), there are two methods: namely: the second indicator of perception target A = total received power - the first indicator of perception target A; or, the second indicator of perception target A = total received power - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B); similarly, there are two ways to calculate the fourth indicator: the fourth indicator of perception target A = the RSRP of the first signal - the first indicator of perception target A; or, the fourth indicator of perception target A = the RSRP of the first signal - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B)

[0207] Method 2: Calculate a perception-related index for multiple perception targets. For example, in Figure 4, determine the signal path associated with any perception target, and then determine these signal paths as signal paths associated with the perception target. This is equivalent to treating multiple perception targets as a virtual perception target and then calculating the perception-related index corresponding to the virtual perception target.

[0208] It should be noted that the above calculation method is only an example, and the embodiments of this application do not limit the specific calculation method of the indicator.

Alternatively, the communication-related indicator may be measured multiple times in a row to meet the switching condition.

[0259] The above-mentioned measurement identifier is used to indicate at least one of the measurement report configuration and the measurement object, which can be understood as that the indication of at least one of the measurement report configuration and the measurement object can be achieved through the measurement identifier. For example, if the measurement report configuration and the measurement object are pre-agreed between devices or protocols, then the identifier can be used for direct indication to save transmission overhead.

[0271] The perception-related indicator associated with the second signal satisfies the first indicator condition, which may be that the perception-related indicator associated with the second signal exceeds a preset threshold, or that the perception-related indicator associated with the second signal is better than the perception-related indicator associated with the first signal; the perception-related indicator associated with the third signal satisfies the second indicator condition, which may be that the perception-related indicator associated with the third signal exceeds a preset threshold, or that the perception-related indicator associated with the third signal is better than the perception-related indicator associated with the first signal; for example, the received power of the signal path associated with the perception target obtained based on the second signal or the third signal or the perception SINR / SNR / SIR / RSRQ-related indicator exceeds the preset threshold. The preset threshold may be agreed upon by protocol or configured on the network side, or may be associated with the value of at least one indicator obtained based on the measurement of the first signal. For example, if the received power of the signal path associated with the perception target obtained based on the first signal is P1, then the preset threshold value is α*P1, where α is a scaling factor.

[0272] The perception measurement quantity of the second signal satisfies the first measurement quantity condition by, for example, the perception measurement quantity of the second signal exceeding a preset threshold, or the perception measurement quantity of the second signal being better than the perception measurement quantity of the first signal. The perception measurement quantity of the third signal satisfies the second measurement quantity condition by, for example, the perception measurement quantity of the third signal exceeding a preset threshold, or the perception measurement quantity of the third signal being better than the perception measurement quantity of the first signal. For example, the distance d1 from the first device to the perception target measured based on the second signal is ≥ α*the distance d2 from the perception target to the second device, where α is a scaling factor; or d1-d2 exceeds a preset threshold; or the distance d3 from the perception target to the second device measured based on the third signal is lower than a preset threshold.

[0275] The position information of the perceived target, or the direction information relative to the second device, is used to help the candidate target device adjust the spatial filter / spatial filter coefficient (the received beam used) when receiving the second signal, or adjust the spatial filter / spatial filter coefficient when sending and receiving the third signal, or adjust the spatial filter / spatial filter coefficient when sending the fourth signal;

[0276] The location information of the first device, or the direction information of the first device relative to the candidate target device, or the distance information between the first device and the second device

[0282] In a case where measurement switching is determined based on the measurement report, the first device sends a switching command to the second device, where the switching command is used to indicate that measurement of the perception target will be switched to the second device.

[0283] The measurement report of the second signal or the third signal may be received by the first device as feedback from the second device, such as when the second device performs handover measurement, obtains the measurement report, and sends it to the first device. Alternatively, the handover measurement report of the fourth signal may be obtained by the first device performing handover measurement on the fourth signal, or by the receiving device of the first signal performing measurement and sending the handover measurement report to the first device.

[0286] The above-mentioned determination of measurement switching based on the measurement report may be that the first device decides on measurement switching based on the above-mentioned switching measurement report, such as the above-mentioned switching measurement report indicates that the second device performs perception measurement better than the above-mentioned source node performs perception measurement, or the above-mentioned switching measurement report indicates that the measurement result of the second device meets the preset conditions, such as the signal quality is higher than the preset threshold, or the above-mentioned switching measurement report indicates that the distance between the second device and the perception target is within a preset range, etc.

[0287] The switching command may switch the signal sending device that measures the perception target to the second device, or switch the signal receiving device that measures the perception target to the second device. Furthermore, the switching command may switch at least one of the signal sending device or the signal receiving device that measures the perception target, such as switching the signal sending device and the signal receiving device, or switching only the signal sending device, or switching only the signal receiving device. When switching the signal sending device and the signal receiving device, the switching command is sent to both devices, respectively.

[0288] In one of the above optional implementations, a switching command is sent to the second device, thereby switching the measurement of the perception target to the second device, thereby improving the perception performance.

[0289] It should be noted that the embodiments of the present application are not limited to sending the above-mentioned switching command based on the above-mentioned switching measurement report. For example, the switching command can also be sent without obtaining the switching measurement report. For example, the first device directly sends the switching command based on the above-mentioned event information. There is no specific limitation on this.

[0292] The candidate device for signal transmission in the switching measurement is a device that may transmit signals before and after the switching. If the switching measurement does not meet the requirements, it will not be used as the target device for the final switching. If the switching measurement meets the requirements, the device will be switched to.

[0293] The signal receiving candidate device of the above switching measurement refers to the device that may receive signals before and after switching. If the switching measurement does not meet the requirements, it will not be used as the final switching target device. If the switching measurement meets the requirements, switching will be carried out to the device.

Its specific implementation can refer to the relevant description of the embodiment shown in Figure 3. In order to avoid repeated description, this embodiment will not be repeated.

[0359] The following describes the method provided in the embodiments of the present application through multiple examples:

[0360] Example 1:

[0361] This embodiment mainly describes a process in which the perception signal sending device remains unchanged and the perception signal receiving device is switched.

[0362] In this embodiment, device A sends a sensing signal, and device B receives and measures the sensing signal. Switching to device A sending a sensing signal, and device C receiving and measuring the sensing signal includes the following steps:

[0363] Step 1: Trigger the measurement.

[0364] Device A transmits a first signal, device B receives the first signal and performs perception measurement. When a measurement switching trigger event is met, device A or the perception network function (first device) sends switching measurement configuration information to the candidate target device (second device).

[0365] The measurement switching triggering event includes at least one of the following:

[0371] The above-mentioned perception-related indicators or communication-related indicators reaching the preset threshold value can be based on the perception SINR / SNR / SIR / RSRQ-related indicators obtained by measuring the first signal being less than the preset value. Optionally, the perception SINR / SNR / SIR / RSRQ-related indicators measured for multiple consecutive times can be less than the preset value.

[0372] The above-mentioned sensed measurement value reaching the preset threshold may be, for example, that the distance d1 between the sensed target and device B exceeds a preset value; or that the position coordinates of the sensed target meet specific conditions, i.e., are located in a specific area; or that the movement speed of the sensed target exceeds a preset value;

For example, if other high-priority sensing / communication / synaesthesia services suddenly occur, it is necessary to evaluate whether to initiate a sensing switching process based on the remaining available sensing resources.

[0380] Alternatively, device A or device B may receive an awareness switching instruction or an instruction to stop providing awareness services from the first device.

[0391] The above signal resource identifier is used to distinguish different signal resource configurations;

[0392] The signal usage indicates whether the target signal is used for communication (e.g., channel measurement, channel estimation, synchronization, carrying data information, etc.), a signal used for sensing, or a signal used for both communication and sensing. Specifically, it may also indicate which sensing service the signal is used for, or which type of sensing service the signal is used for.

[0397] The guard interval can be the time interval from the moment the signal ends to the moment the latest echo signal of the signal is received.

[0399] The frequency domain resource length may be a frequency domain bandwidth, which is inversely proportional to the distance resolution. The frequency domain bandwidth of each signal is B≥c / (2ΔR), where c is the speed of light and ΔR is the distance resolution.

[0400] The frequency domain resource spacing represents the spacing between adjacent signal frequency domain resource units and can be expressed as the number of REs or RBs, or as a density value (Density). For example, Density = 1 indicates that there is one RE in each RB used to carry the signal. The frequency domain resource spacing is inversely proportional to the maximum unambiguous distance / delay. For an OFDM system, when subcarriers are mapped continuously, the frequency domain spacing is equal to the subcarrier spacing.

[0401] The above-mentioned time domain starting position can be a starting time point, or a starting symbol, time slot, or frame index.

[0402] The time domain resource length may be a burst duration, and the time domain resource length is inversely proportional to the Doppler resolution.

[0403] The time domain resource interval may be a time interval between two adjacent signal resource units, and the time domain resource interval is associated with a maximum unambiguous Doppler frequency shift or a maximum unambiguous speed.

[0404] The above-mentioned time domain resource characteristics may be periodic transmission, semi-persistent transmission or aperiodic transmission.

[0406] The above sequence information may include sequence type information (such as ZC sequence, PN sequence, etc.), sequence generation method or sequence length, etc.

[0407] The above-mentioned signal direction may be angle information or beam information of signal transmission.

[0408] The above-mentioned QCL relationship may indicate that the above-mentioned signal includes multiple resources, each resource is associated with a synchronization signal block (Synchronization Signal Block, SSB) QCL, and the QCL includes type A, type B, type C or type D.

[0409] The above antenna port information may be the maximum number of antenna ports or an antenna port index.

[0410] The above-mentioned cyclic prefix (CP) information may include a CP type or a CP length, etc., wherein the CP type may include a normal cyclic prefix (NCP), an extended cyclic prefix (ECP) or a newly designed perception measurement-specific CP, etc.

[0431] After receiving the switching measurement configuration information, the second device performs switching measurement based on the second signal or the third signal, and feeds back a switching measurement report to the perception network function or device A; the switching measurement report includes at least one of the value of the perception measurement amount, the value of the perception-related indicator or the communication-related indicator, and an identifier that satisfies the corresponding measurement event.

[0432] Alternatively, device A performs switching measurement based on the fourth signal sent by the second device to obtain a switching measurement report and sends the report to the perception network function.

[0433] Among them, the first signal and the second signal can be the same signal, that is, device A transmits the first signal and device B receives it and performs perception measurement; the second device receives the first signal and performs switching measurement (when the first signal and the second signal are the same signal, that is, the configuration information of the second signal is the configuration information of the first signal); or, the second device sends a third signal and receives the echo signal of the third signal to perform switching measurement; or, the second device sends a fourth signal, device A receives the fourth signal and performs switching measurement.

[0434] The first signal and the second signal can be different signals, that is, device A transmits the first signal and device B receives it and performs perception measurement. When the measurement switching trigger event is met, device A sends the second signal and the second device receives the second signal to perform switching measurement; or, the second device sends the third signal and receives the echo signal of the third signal to perform switching measurement; or, the second device sends the fourth signal, device A receives the fourth signal and performs switching measurement.

[0435] Step 3: Switch judgment.

[0436] Device A decides whether to initiate handover based on the handover measurement report reported by the candidate target device, or based on measurement of the fourth signal sent by the second device.

[0437] Optionally, device A receives a handover measurement report from the second device and reports the handover measurement report to the perception network function, and the first device determines whether to initiate a handover request; or, the perception network function determines whether to initiate a handover based on the handover measurement report received from the second device; or, device A obtains a handover measurement report based on measurement of a fourth signal sent by the second device and reports the handover measurement report to the perception network function, and the perception network function determines whether to initiate a handover request;

[0438] If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, still perform perception measurement based on device A sending the first signal and device B receiving it, or stop the perception measurement.

[0439] If handover is initiated, device A or the perception network function determines a candidate target device and sends a handover request message to the candidate target device, requesting the at least one second device to perform perception measurement.

[0440] The handover request information also includes at least one of the following information:

[0441] Perception requirements, which may include perception target area / object type, required perception function, perception purpose, perception results, etc.);

[0442] Perception service quality (QoS), including at least one of the following: perception resolution (which can be subdivided into: ranging resolution, angular resolution, velocity resolution, imaging resolution), perception accuracy (which can be subdivided into: ranging accuracy, angular accuracy, velocity accuracy, positioning accuracy, etc.), perception range (which can be subdivided into: ranging range, velocity range, angular range, imaging range, etc.), perception latency (the time interval from the sending of the perception signal to the acquisition of the perception result, or the time interval from the initiation of the perception request to the acquisition of the perception result), perception update rate (the time interval between two adjacent perception executions and the acquisition of the perception result), detection probability (the probability of correctly detecting the perception object when it is present), false alarm probability (the probability of incorrectly detecting the perception target when the perception object is not present), perception security, and perception privacy);

[0443] Perceptual measurement quantity;

[0444] Perceptual measurement results, such as perception results directly or indirectly obtained based on at least one perceptual measurement quantity;

[0445] Perception conditions, such as at least one of the perception start time, perception end time, and perception duration;

[0446] Prior information of the sensing target or sensing area, such as at least one of the sensing target type, sensing target location / area, and sensing target historical state (speed, angle, distance, acceleration, spatial orientation);

[0447] A sensing mode switching success decision condition (for example, indicating that a measurement result of at least one sensing measurement quantity and / or communication measurement quantity reaches a preset threshold within a preset time / preset number of times);

[0448] Handover type, including hard handover and soft handover.

[0449] Step 4: Perform the switch.

[0450] After receiving the handover request message, the second device decides whether to accept the handover / execute the sensing. There are two cases:

[0451] If agreed, the second device sends a handover response message to the handover request message sender (device A or the perception network function), where the handover response message indicates to the handover request message sender that the handover response message sender agrees to perform the perception measurement.

[0452] Optionally, the second device feeds back suggested second signal configuration information in the handover response information. The second signal configuration information is used for signal configuration for the second device to perform sensing measurement.

[0453] If not agreed, the second device sends a switching rejection message to the first request information sender (device A or perception network function), where the switching rejection message indicates to the first request information sender that the switching rejection message sender does not perform perception.

[0454] The subsequent processing may be one of the following: i. Device A or the perception network function re-determines the second device; ii. Maintains the current perception; iii. Ends the current perception;

[0455] After receiving the handover response information, device A or the perception network function determines at least one target device in the second device as a device for performing perception measurement after the handover, and device A or the perception network function sends a handover command to the target device to notify the target device to perform perception measurement;

[0456] Specifically, the following situations are included:

[0457] After device A or the perception network function sends a handover command to the target device, it notifies device B to end the perception measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.); device A continues to send the second signal, and the target device performs perception measurement based on the second signal. The first signal is the signal originally sent by device A to device B for perception measurement, and the second signal is the signal sent by device A to the target device for handover measurement. The target device reuses this signal for subsequent perception measurement.

[0458] After device A or the perception network function sends a handover command to the target device, it notifies device B to end the perception measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.); device A sends a fifth signal, and the target device performs perception measurement based on the fifth signal. The first signal is the original signal sent by device A and received by device B for perception measurement, and the fifth signal is the new signal sent by device A for perception measurement. The target device performs subsequent perception measurement based on the fifth signal.

[0459] After device A or the perception network function sends a handover command to the target device, it notifies device B to end the perception measurement operation. Device A continues to send the first signal, and the target device performs perception measurement based on the first signal. The first signal is the signal originally sent by device A and received by device B for perception measurement, and the signal sent by device A to the target device for handover measurement (i.e., the first signal and the second signal are the same signal). The target device reuses the signal for subsequent perception measurement.

[0460] After device A or the perception network function sends a handover command to the target device, the target device performs a perception measurement based on the second signal. After the target device completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related indicator or communication-related indicator exceeds a preset threshold), the target device sends feedback information to device A or the perception network function. Device A or the perception network function notifies device B to end the perception measurement operation. Device A stops sending the first signal, releasing the occupied resources. The first signal is the signal originally sent by device A to device B for perception measurement, and the second signal is the signal sent by device A to the target device for handover measurement. The target device reuses this signal for subsequent perception measurements.

[0461] After device A or the perception network function sends a handover command to the target device, it sends a fifth signal to the target device. The target device performs perception measurements based on the fifth signal. After the target device completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related indicator or communication-related indicator exceeds a preset threshold), the target device sends feedback information to device A or the perception network function. Device A or the perception network function notifies device B to end the perception measurement operation. Device A stops sending the first signal and releases occupied resources. The first signal is the original signal sent by device A and received by device B for perception measurement. The fifth signal is a new signal sent by device A for perception measurement. The target device performs subsequent perception measurements based on the fifth signal.

[0462] After device A or the perception network function sends a handover command to the target device, device A continues to send the first signal, and the target device performs perception measurements based on the first signal. After the target device completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related or communication-related indicator exceeds a preset threshold), the target device sends feedback information to device A or the perception network function, and device A or the perception network function notifies device B to end the perception measurement operation. The first signal is the original signal sent by device A to device B for perception measurement, and the signal sent by device A to the target device for handover measurement (i.e., the first signal and the second signal are the same signal). The target device reuses this signal for subsequent perception measurements.

[0463] Example 2:

[0464] This embodiment mainly describes a process in which the perception signal receiving device remains unchanged and the perception signal sending device is switched.

[0465] In this embodiment, device A sends a sensing signal, device B receives the sensing signal and measures, and then the process switches to device C sending a sensing signal, device B receiving the sensing signal and measures.

[0466] Step 1: Trigger the measurement.

[0467] Device A transmits a first signal, device B receives the first signal and performs perception measurement. When a measurement switching trigger event is met, device B or the perception network function sends switching measurement configuration information to the candidate target device (second device);

[0468] The definition of the measurement switching triggering event is the same as that in the first embodiment.

[0469] The handover measurement configuration information includes at least one of the following:

[0470] Measurement object information, measurement report configuration, measurement identification, measurement content information, measurement event information, and measurement auxiliary information.

[0471] The measurement object information includes at least one of the following:

[0472] Configuration information of a second signal that the second device needs to receive, where the second signal is sent by device B and received and measured by the second device;

[0473] Configuration information of a third signal, wherein the third signal is a signal that the second device needs to send and is received and measured by the second device;

[0474] Configuration information of a fourth signal, where the fourth signal is a signal sent by the second device and received and measured by device B.

[0475] The measurement report configuration includes a measurement report configuration for the second signal or the third signal, such as a reporting principle of the second device to device B or the perception network function, which may be periodic reporting or event-triggered reporting; the type of reference signal used for measurement; and a measurement report format, such as the number of beams reported.

[0476] The measurement content information may include at least one of the following:

[0477] At least one perception-related indicator or communication-related indicator associated with the second signal or the third signal, such as a received power of a signal path associated with the perception target obtained based on the second signal or an indicator related to perception SINR / SNR / SIR / RSRQ; or a received power of a signal path associated with the perception target obtained based on the third signal or an indicator related to perception SINR / SNR / SIR / RSRQ; the preset threshold may be associated with the value of at least one perception-related indicator or communication-related indicator obtained based on the measurement of the first signal, for example, if the received power of the signal path associated with the perception target obtained based on the first signal is P1, then the threshold value is α*P1, where α is a scaling factor;

[0478] At least one perception measurement quantity associated with the second signal or the third signal (which may be one or a combination of several), such as the distance d1 from device B to the perception target or the distance d2 from the perception target to the second device measured based on the second signal; or the difference or ratio of d1 and d2; or the bistatic distance d_bi (d_bi=d1+d2) measured based on the second signal; or the distance d3 from the perception target to the second device measured based on the third signal;

[0479] The measurement event information is used to indicate the measurement event and related parameters, and may include at least one of the following:

[0480] The value of at least one perception-related indicator or communication-related indicator obtained based on the measurement of the second signal or the third signal meets a preset condition, for example, the received power of the signal path associated with the perception target or the perception SINR / SNR / SIR / RSRQ-related indicator obtained based on the measurement of the second signal or the third signal exceeds a preset threshold;

[0481] A value of at least one perceptual measurement quantity measured based on the second signal or the third signal satisfies a preset condition, for example, d1 ≥ α * d2, where α is a scaling factor, measured based on the second signal; or d1 - d2 exceeds a preset threshold; or d3 measured based on the third signal is lower than a preset threshold;

[0482] The measurement assistance information may include at least one of the following:

[0483] sensing the location information of the target, or the direction information relative to the second device (to help the second device adjust the spatial filter / spatial filter coefficient (the received beam used) when receiving the second signal, or adjust the spatial filter / spatial filter coefficient when sending and receiving the third signal, or adjust the spatial filter / spatial filter coefficient when sending the fourth signal);

[0484] The location information of device B, or the direction information of device B relative to the second device, or the distance information between device B and the second device

[0485] Recommended transmit or receive configuration, such as whether to use omnidirectional transmission or reception, or the transmit or receive beam index used.

[0486] Device B or the second device may determine whether a measurement event is satisfied based on an average value of multiple measurement quantities / indicators at different times (layer 1 filtering and / or layer 3 filtering), or based on whether the values ​​of the measurement quantities / indicators measured multiple times in succession meet preset conditions, thereby avoiding randomness / ping-pong effects caused by judging based on a single result.

[0487] The determination of the second device is based on second device status information (which may be sent by the second device to device B or the perception network function, and device B or the perception network function determines the second device list based on the second device status information; or device B obtains the second device list from the perception network function), where the second device status information includes at least one of the following:

[0488] The location information of the second device, or the distance and direction information relative to device B;

[0489] second device antenna panel orientation information;

[0490] sensing capability information of the second device;

[0491] Resource information currently available for sensing by the second device;

[0492] channel state information of the second device;

[0493] If the second device is a terminal, it also includes UE status information.

[0494] Step 2: Perform the measurement.

[0495] After receiving the switching measurement configuration information, the second device performs switching measurement based on the second signal or the third signal, and feeds back a switching measurement report to the perception network function or device B; the switching measurement report includes at least one of the value of the perception measurement amount, the value of the perception-related indicator or the communication-related indicator, and an identifier that satisfies the corresponding measurement event.

[0496] Alternatively, device B performs switching measurement based on the fourth signal sent by the second device to obtain a switching measurement report and sends it to the perception network function.

[0497] Step 3: Switch judgment.

[0498] Device B decides whether to initiate handover based on the handover measurement report reported by the second device, or based on measurement of the fourth signal sent by the second device.

[0499] Optionally, device B receives the handover measurement report from the second device and reports the handover measurement report to the perception network function, and the perception network function determines whether to initiate a handover request; or, the perception network function determines whether to initiate a handover based on the handover measurement report received from the second device; or, device B obtains the handover measurement report based on the measurement of the fourth signal sent to the candidate target and reports it to the perception network function, and the perception network function determines whether to initiate a handover request;

[0500] If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, still perform perception measurement based on device A sending the first signal and device B receiving it, or stop the perception measurement.

[0501] If switching is initiated, device B or the perception network function determines the second device and sends a switching request message to it. The switching request message is defined in the same manner as in the first embodiment.

[0502] Step 4: Perform the switch.

[0503] After receiving the handover request message, the second device decides whether to accept the handover / execute the sensing. There are two cases:

[0504] If agreed, the second device sends a switching response message to the sender of the switching request message (device B or the cognitive network function).

[0505] If not agreed, the second device sends a switching rejection message to the sender of the first request message (device B or the perception network function).

[0506] The subsequent processing may be one of the following: i. Device B or the perception network function re-determines the second device; ii. Maintains the current perception; iii. Ends the current perception;

[0507] After receiving the handover response information, device B or the perception network function determines at least one target device in the second device as a device for performing perception measurement after the handover, and device B or the perception network function sends a handover command to the target device to notify the target device to perform perception measurement;

[0508] Specifically, the following situations are included:

[0509] After device B or the perception network function sends a handover command to the target device, it notifies device A to end the perception measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.). The target device sends a fourth signal, and device B performs perception measurement based on the fourth signal. The first signal is the signal originally sent by device A and received by device B for perception measurement, and the fourth signal is the signal sent by the target device to device B for handover measurement. The target device reuses this signal for subsequent perception measurement.

[0510] After device B or the perception network function sends a handover command to the target device, it notifies device A to end the perception measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.). The target device sends a fifth signal, and device B performs perception measurement based on the fifth signal. The first signal is the original signal sent by device A and received by device B for perception measurement, and the fifth signal is the new signal sent by the target device for perception measurement. The target device performs subsequent perception measurement based on the fifth signal.

[0511] After device B or the perception network function sends a handover command to the target device, device B performs perception measurements based on the fourth signal. After device B completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related or communication-related indicator exceeds a preset threshold), device B or the perception network function notifies device A to end the perception measurement operation. Device A stops sending the first signal, releasing the occupied resources. The first signal is the signal originally sent by device A to device B for perception measurement, and the fourth signal is the signal sent by the target device to device B for handover measurement. The target device reuses this signal for subsequent perception measurements.

[0512] After device B or the perception network function sends a handover command to the target device, the target device sends a fifth signal. Device B performs perception measurements based on the fifth signal. After device B completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related or communication-related indicator exceeds a preset threshold), device B or the perception network function notifies device A to terminate the perception measurement operation. Device A stops sending the first signal, releasing occupied resources. The first signal is the original signal sent by device A and received by device B for perception measurement, and the fifth signal is the new signal sent by the target device for perception measurement. The target device and device B perform subsequent perception measurements based on the fifth signal.

[0513] Example 3:

[0514] This embodiment mainly describes a process in which both the perception signal sending device and the perception signal receiving device are switched.

[0515] In this embodiment, device A sends a sensing signal, device B receives the sensing signal and measures, and then the process switches to device C sending a sensing signal, device D receiving the sensing signal and measures.

[0516] Step 1: Trigger the measurement.

[0517] Device A transmits a first signal, device B receives the first signal and performs perception measurement. When the measurement switching trigger event is met, the perception network function (perception network function) sends switching measurement configuration information to the second device (including the signal sending candidate device and the signal receiving candidate device).

[0518] The definition of the measurement switching trigger event is the same as that in the first embodiment.

[0525] At least one sensing measurement associated with the second signal (which may be one or a combination of several), such as the distance d1 from the candidate signal transmitting device to the sensing target or the distance d2 from the sensing target to the candidate signal receiving device measured based on the second signal; or the difference or ratio of d1 to d2; or the bistatic distance d_bi (d_bi=d1+d2) measured based on the second signal;

[0526] The measurement event information is used to indicate the measurement event and related parameters, and may include at least one of the following:

[0527] The value of at least one perception-related indicator or communication-related indicator obtained based on the measurement of the second signal meets a preset condition, for example, the received power of the signal path associated with the perception target or the perception SINR / SNR / SIR / RSRQ-related indicator obtained based on the measurement of the second signal exceeds a preset threshold;

[0528] The preset threshold may be associated with a value of at least one perception-related indicator or communication-related indicator obtained based on measurement of the first signal. For example, if the received power of the signal path associated with the perception target obtained based on the first signal is P1, then the threshold value is α*P1, where α is a scaling factor.

[0529] The value of at least one perception measurement quantity obtained based on the measurement of the second signal satisfies a preset condition, for example, d1 or d2 obtained based on the measurement of the second signal is less than a preset threshold, or the bistatic distance d_bi (d_bi=d1+d2) obtained based on the measurement of the second signal is less than a preset threshold;

[0530] The preset threshold may be associated with a value of at least one perception measurement quantity obtained based on the measurement of the first signal, such as the distance from the perception target to device A obtained based on the first signal, or the distance from the perception target to device B, or the sum of the distance from the perception target to device A and the distance to device B.

[0531] The measurement assistance information may include at least one of the following:

[0532] sensing the location information of the target, or the direction information relative to the second device (to help the second device adjust the spatial filter / spatial filter coefficient (the received beam used) when receiving the second signal, or adjust the spatial filter / spatial filter coefficient when sending and receiving the third signal, or adjust the spatial filter / spatial filter coefficient when sending the fourth signal);

[0533] Location information of device A or device B, or direction information of device A or device B relative to a second device, or distance information between device A or device B and a second device

[0534] Recommended transmit or receive configuration, such as whether to use omnidirectional transmission or reception, or the transmit or receive beam index used.

[0535] Among them, the second device determines whether the measurement event is met based on the average value of multiple measurement quantities / indicators at different times (layer 1 filtering and / or layer 3 filtering), or whether the values ​​of the measurement quantities / indicators measured multiple times in succession meet the preset conditions, thereby avoiding the randomness / ping-pong effect brought about by judgment based on a single result.

[0536] The determination of the second device is based on second device status information (which may be sent by the second device to the perception network function, and the perception network function determines the second device list based on the second device status information). The second device status information includes at least one of the following:

[0537] The location information of the second device, or the distance and direction information relative to device A or device B;

[0538] second device antenna panel orientation information;

[0539] sensing capability information of the second device;

[0540] Resource information currently available for sensing by the second device;

[0541] channel state information of the second device;

[0542] If the second device is a terminal, it also includes terminal status information.

[0543] Step 2: Perform the measurement.

[0544] After receiving the switching measurement configuration information, the second device performs switching measurement based on the second signal, and feeds back a switching measurement report to the perception network function; the switching measurement report includes at least one of the value of the perception measurement amount, the value of the perception-related indicator or the communication-related indicator, and an identifier that satisfies the corresponding measurement event.

[0545] Step 3: Switch judgment.

[0546] The perception network function determines whether to initiate a handover based on the handover measurement report reported by the second device.

[0547] If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, still perform perception measurement based on device A sending the first signal and device B receiving it, or stop the perception measurement.

[0548] If switching is initiated, the perception network function determines the second device and sends switching request information to it. The switching request information is defined the same as in the first embodiment.

[0549] Step 4: Perform the switch.

[0550] After receiving the handover request message, the second device decides whether to accept the handover / execute the sensing. There are two cases:

[0551] If agreed, the second device sends a switching response message to the switching request message sender (perceptual network function).

[0552] If not agreed, the second device sends a switching rejection message to the first request information sender (perceptual network function).

[0553] The subsequent processing may be one of the following: i. the perception network function re-determines the second device; ii. maintains the current perception; iii. ends the current perception;

[0554] After receiving the handover response information, the perception network function determines at least one target device in the second device, including determining at least one first target device (signal sending device) from the signal sending candidate devices and determining at least one second target device (signal receiving device) from the signal receiving candidate devices as the device for performing perception measurement after the handover. The perception network function sends a handover command to the target device to notify the target device to perform perception measurement;

[0555] Specifically, the following situations are included:

[0556] After the perception network function sends a handover command to the target device, it notifies device A and device B to end the perception measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.); the first target device sends a second signal, and the second target device performs perception measurement based on the second signal. The first signal is the signal originally sent by device A and received by device B for perception measurement, and the second signal is the signal sent by the first target device and received by the second target device for handover measurement. The target device reuses this signal for subsequent perception measurement.

[0557] After the perception network function sends a handover command to the target device, it notifies device A to end the perception measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.). The first target device sends a third signal, and the second target device performs perception measurement based on the third signal. The first signal is the original signal sent by device A to device B for perception measurement, and the third signal is a new signal sent by the first target device to the second target device for perception measurement. The target device performs subsequent perception measurement based on the third signal.

[0558] After the perception network function sends a handover command to the target device, the first target device sends a second signal, and the second target device performs perception measurement based on the second signal. After the target device completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related indicator or communication-related indicator exceeds a preset threshold), the perception network function notifies device A and device B to end the perception measurement operation. Device A stops sending the first signal, releasing the occupied resources. The first signal is the signal originally sent by device A to device B for perception measurement, and the second signal is the signal sent by the first target device to the second target device for handover measurement. The target device reuses this signal for subsequent perception measurement.

[0559] After the perception network function sends a handover command to the target device, the first target device sends a third signal, and the second target device receives the third signal to perform perception measurements. After the target device completes at least one perception measurement and obtains a perception result (optionally, and the corresponding perception-related or communication-related indicator exceeds a preset threshold), the perception network function notifies device A and device B to end the perception measurement operation.
