In the following, in combination with the accompanying drawings, a measurement configuration information sending method, a receiving method, an apparatus and a device provided in an embodiment of the present application are described in detail through some embodiments and their application scenarios.

Please refer to FIG. 3, which is a flow chart of a method for sending measurement configuration information provided by an embodiment of the present application. As shown in FIG. 3, the method includes the following steps:

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.

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

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 a first signal, or the first device obtains the event information through measurement.

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

The first device measures the first signal to obtain the event information;

The first device receives the event information.

The first signal may be a signal sent by the first device, which is sent and received by the first device itself, or the first device sends the first signal, the second device measures the first signal, and feeds back the event information to the first device.

Alternatively, the first signal is sent by other devices, and the first device measures the first signal to obtain event information.

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

The dedicated signal of 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.

Among them, the reference signal can be a demodulation reference signal (Demodulation Reference Signal, DMRS), a channel state information reference signal (Channel State Information, Reference Signal, CSI-RS), a sounding reference signal (Sounding Reference Signal, SRS) or a positioning reference signal (Positioning Reference Signal, PRS), etc.;

The above-mentioned synchronization signal can be a primary synchronization signal (Primary Synchronization Signal, PSS) or a secondary synchronization signal (Secondary Synchronization Signal, SSS), etc.

The above-mentioned signals carrying communication data may be physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical downlink control channel (PDCCH) or physical uplink control channel (PUCCH), etc.

The above measurement switching triggering event indicates that the event is used to trigger measurement switching, such as perception switching (or referred to as perception measurement switching).

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 a process of receiving the first signal.

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

The above indicators satisfying the switching conditions may be determined by the protocol or the network side equipment, or by the equipment generating the above event information. For example: the perception-related indicators reach the preset threshold, such as the perception-related indicators are less than the preset threshold, or the perception-related indicators are within the preset threshold range, or the perception-related indicators indicate that the perception performance has deteriorated, or the perception-related indicators indicate that the perception requirements cannot be met, etc. Or the perception-related indicators measured multiple times in succession may satisfy the above switching conditions.

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 the measurement performance.

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

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.

The above-mentioned switching measurement configuration information is used to configure the switching measurement, such as configuring the measurement object, configuring the measurement identifier, configuring the measurement content, etc. Among them, the switching measurement means that the measurement is performed for the measurement switching to trigger the measurement switching, such as the perception switching, so that the measurement switching can be triggered by the above-mentioned switching measurement configuration information, such as triggering the perception switching.

In some implementations, the switching measurement configuration information may also be used to indicate measurement switching, such as indicating perception switching, or to send a command indicating measurement switching, such as a switching command for perception switching, after sending the switching measurement configuration information.

In the embodiment of the present application, the above steps can realize the transmission of switching measurement configuration information between devices when a measurement switching trigger event is met, so that the devices support switching measurement, thereby improving the perceived measurement performance of the devices.

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 perception targets or perception devices or other environmental conditions.

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

The above-mentioned execution of the handover measurement behavior may include at least one of the following:

performing a switching measurement based on the second signal;

performing a switching measurement based on a third signal;

Sending a fourth signal, where the fourth signal is a measurement signal for switching measurement;

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.

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.

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.

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

The signal path associated with the above-mentioned perception target may be a signal path affected by the perception target or a signal path passing through the perception target.

In the above optional implementation, since the perception-related indicators include perception indicators related to received power, it is possible to trigger measurement switching based on received power, so that measurement switching is more reliable. In addition, it is also possible to trigger measurement switching by sensing the received power of the signal path associated with the target, and the received power of the signal path associated with the target can more intuitively reflect whether the measurement needs to be switched. Therefore, the above first indicator can make the measurement switching more reliable.

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 sensing 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, so that 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.

The above-mentioned perception indicator related to interference or noise power may refer to that the perception indicator is 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, and an interference indicator associated with both interference and noise power.

In the above optional implementation manner, since the perception-related indicator includes a perception indicator related to interference or noise power, it is possible to take interference or noise into consideration when determining measurement switching, so that the measurement switching is more reliable.

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

A fourth indicator, the fourth indicator being a linear average of the powers of other signal paths except 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;

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.

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.

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.

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:

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.

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

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, the adjacent channel interference power and the thermal noise power, etc. And the total received power may also be the linear average value (in W) of the total received power of the first device on the target resource.

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 K1 may be a protocol agreement or a network side configuration. In some implementations, the power corresponding to the RSSI may also be RSSI, that is, total received power = RSSI.

The above-mentioned received power of the first signal refers to the reference signal received power (Reference Signal Received Power, RSRP) of the first signal.

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.

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.

In the above implementation, 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.

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

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.

The above target coefficient can be expressed as K2, such as the eighth indicator = K2*the first indicator/total received power, K2 is the coefficient, and K2 can be specifically a protocol agreement or a network side configuration.

In this implementation manner, through 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.

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

Indicators related to perceived SINR, indicators related to perceived SNR, indicators related to perceived signal-to-interference ratio (Signal Interference Ratio, SIR), and indicators related to perceived RSRQ.

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

The parameter meets the first preset threshold, or the parameter is within the first preset interval;

The parameters satisfy the preset modulation rules;

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 interval;

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.

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

Amplitude, power, intensity, energy, phase, Doppler, delay, angle;

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

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

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 perceived prior information or perceived requirements. The above-mentioned parameter satisfying the first preset threshold may be that the parameter exceeds or is equal to the first preset threshold, the above-mentioned parameter difference with the first-reaching signal path satisfies the second preset threshold may be 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 satisfies the third preset threshold may be that the parameter difference with the reference signal path exceeds or is equal to the third preset threshold.

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~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 according to the person's gender and age (for example, 15 to 30 times/minute, which can be used as perception prior information, and the corresponding Doppler range can be calculated, 0.25 to 0.5Hz).

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

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 or a backscatter device or a RIS, that is, the signal path associated with the sensing target may be a signal path modulated and reflected by a tag or a backscatter device or a RIS.

In one of the above optional implementations, it is possible to determine the signal path associated with the perceived target in a variety of ways, which can not only improve the flexibility of determining the signal path associated with the perceived target, but also improve the accuracy of determining the signal path associated with the perceived target based on a variety of ways.

In some implementations, before determining the signal path associated with the perceived target, a signal path set may also be determined, the signal path set including 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. Then, the signal path associated with the perceived target is determined based on at least one of the above items in the signal path set to reduce the amount of calculation.

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.

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 to the first dimension and determines the signal path associated with the perception target in the first dimension. Then, the power of the signal path associated with the perception target is 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.

The first dimension includes one of the following:

Delay dimension;

Doplevi;

Azimuth dimension;

Pitch angle dimension;

A dimension that is a combination of at least two of the delay dimension, the Doppler dimension, the azimuth dimension, and the elevation dimension. For example, the delay-Doppler dimension, the delay-Doppler-angle dimension, etc.;

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 to 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.

A method for determining a signal path associated with a perception target in a channel response obtained by measuring a first signal (referred to as a perception path for short):

Determine the signal path set. The signal paths in the signal path set include the paths whose amplitude, power, intensity or energy exceeds a certain threshold among all paths after the channel response is transformed to the first dimension. For example, in Figure 4, signal paths 0, 1, 2, and 3 are the paths of 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 agreed upon by the protocol. Among them, this step (determining the signal path set) is optional, and the signal path associated with the perception target can be determined only based on the next step.

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:

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

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

The delay of the signal path exceeds the preset threshold or is within the preset range;

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

The difference between the amplitude/power/intensity/energy of the signal path and the first-reach path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset interval, wherein the reference signal path may be a signal path reflected by a known target (e.g., RIS/Backscatter/other known passive targets, etc.);

The Doppler difference between the signal path and the first arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset interval;

The delay difference between the signal path and the first arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset interval;

The angle difference between the first arrival path (such as LOS path) or the reference path exceeds a preset threshold or is within a preset interval;

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.

Among them, the above-mentioned first conditions can also be based on the statistical results of 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 the preset threshold or being within the preset interval in the 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 the preset threshold or are within the preset interval in the preset time window reaches a preset number of times;

The preset threshold or the set interval range is sent by other devices to the receiving device, and is determined by other devices according to the prior perception information or perception requirements. Alternatively, the preset threshold or the preset interval range may be a protocol agreement, or the preset threshold or the preset interval range is determined by the receiving device according to the prior perception information or perception requirements.

The perception prior information or perception requirements include the following information:

Perception services or perception service types, the perception services may be, for example, detecting whether a target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, radar cross-section RCS (Radar Cross Section, RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity/brightness/temperature/atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography and geography. Appearance, 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, such as detection-type perception services (such as intrusion detection and fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (action recognition, identity recognition), etc., according to the function, 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 refinement (coarse-grained perception, fine force perception, etc.), according to power consumption/energy consumption, according to resource occupancy, etc. If the perception service is respiratory monitoring, the corresponding normal breathing rate can be determined according to the gender and age of the person (for example, male: 13 to 21 times/minute, female 15 to 20 times/minute; adult: 12 to 20 times/minute, child: about 30 to 40 times/minute), which can be used as perception prior information;

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 according to the approximate location/distance of the perception object;

Perception object type: The perception object is classified according to its possible motion characteristics. Each perception object type contains information such as the motion speed range, motion acceleration range, and typical RCS range of a typical perception object.

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.

For example, in Figure 4, signal paths 0, 1, 2, and 3 are paths in the signal path set, where 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.

In FIG4 , the channel response is a schematic diagram of multiple signal paths in the first dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation dimension), wherein the horizontal axis is the first dimension and the vertical axis is the normalized amplitude, power, intensity or energy.

For frequency range 1, the reference point of the first indicator can be the antenna connector of the receiving device such as the terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first indicator measured and reported by the receiving device cannot be lower than the indicator of any single receiving channel. For frequency range 2, the first indicator measured by a receiving channel needs to be measured on the combined signals of the multiple antenna units corresponding to the receiving channel.

Calculation method 2 of the first indicator:

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 taken as the first indicator, where N ₁ 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.

The calculation method of the received power of the first signal is:

The received power of the first signal can be obtained by the receiving device obtaining the channel response (Channel Response) H(k), transforming it 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.

Method 2 for calculating the received power of the first signal:

The received power of the first signal may also be the sum of the powers of all signal paths in the signal path set in the first dimension and The difference between , where N ₂ represents the number of signal paths in the signal path set.

The total received power is calculated as:

Total received power

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.

The calculation method of the second indicator is:

The channel response H(k) is subjected to a first filtering process to obtain H _filter1 (k), and then the received signal Y _filter1 (k) after the first filtering process is calculated based on H _filter1 (k) and the first signal X(k), that is, Y _filter1 (k) = H _filter1 (k)X(k). Then, the received signal Y(k) after the first filtering process is subtracted from the received signal Y _filter1 (k) to obtain the interference and noise signal Y _σ1 (k), that is, Y _σ1 (k) = Y(k)-Y _filter1 (k), and then the second indicator is calculated:

The first filtering process is used to eliminate the noise and interference in the first dimension and the path associated with the non-perceptual target. For example, the first filtering process sets the amplitude, power, intensity or energy of the paths other than the signal path associated with the perceptual target in FIG4 to zero. The channel response H _filter1 (k) after the first filtering process does not include the noise and interference and the path associated with the non-perceptual target, but only includes the path associated with the perceptual target.

The calculation method of the third indicator is:

The channel response H(k) is subjected to a second filtering process to obtain H _filter2 (k), and then the received signal Y _filter2 (k) after the second filtering process is calculated based on H _filter2 (k) and the first signal X(k), that is, Y _filter2 (k) = H _filter2 (k)X(k). Then, the received signal Y(k) is subtracted from the received signal Y _filter2 (k) after the second filtering process to obtain the interference and noise signal Y _σ2 (k), that is, Y _σ2 (k) = Y(k)-Y _filter2 (k), and then the third indicator is calculated:

The second filtering process may be a noise interference suppression process in the first dimension (for example, setting the amplitude, power, intensity or energy of the paths other than the signal path set in FIG4 to zero), or a minimum mean square error (MMSE) filter. The channel response H _filter2 (k) after the second filtering process does not contain noise and interference, but only contains the paths in the signal path set.

Calculation method 2 of the third indicator:

According to the average power of multiple signal paths outside the signal path set in the first dimension The third index P _σ2 is calculated, that is Where N represents the number of sampling points in the first dimension.

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 according to sensing prior information or sensing requirements, there are the following methods:

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; at this time, when calculating the second indicator corresponding to a 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 that 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 that there are two perception targets: A and B)

Method 2: Calculate a perception-related index for multiple perception targets. For example, in FIG4 , the signal path associated with any perception target is determined, and then these signal paths are determined 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.

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

The preset threshold may be agreed upon by the 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, 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.

Step 2: Perform the measurement.

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 quantity, the value of the perception-related indicator or the communication-related indicator, and an identifier that satisfies the corresponding measurement event.

Alternatively, device A 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.

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.

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, and device A receives the fourth signal and performs switching measurement.

Step 3: Switch judgment.

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

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 decides whether to initiate a handover request; or, the perception network function decides whether to initiate a handover according to the handover measurement report received from the second device; or, device A obtains a handover measurement report based on a 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 decides whether to initiate a handover request;

If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, to still perform the perception measurement based on the first signal sent by device A and received by device B, or to stop the perception measurement.

If a 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.

Switching type, including hard switching and soft switching.

Step 4: Perform the switch.

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

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

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 perception measurement.

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

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;

After receiving the switching 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 switching, and device A or the perception network function sends a switching command to the target device to notify the target device to perform perception measurement;

Specifically, the following situations are included:

After device A or the perception network function sends a switching 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 to device B for perception measurement, and the signal sent by device A to the target device for switching measurement (that is, the first signal and the second signal are the same signal), and the target device reuses the signal for subsequent perception measurement;

After device A or the perception network function sends a switching command to the target device, the target device performs perception measurement based on the second signal. When 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 value), 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, and device A stops sending the first signal to release the occupied resources. Among them, the first signal is the signal sent by the original device A to device B for perception measurement, and the second signal is the signal sent by device A to the target device for switching measurement. The target device reuses the signal for subsequent perception measurement;

After device A or the perception network function sends a switching command to the target device, it sends a fifth signal to the target device, and the target device performs perception measurement based on the fifth signal. When 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 value), 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, and device A stops sending the first signal to release the occupied resources. Among them, the first signal is the original signal sent by device A to device B for perception measurement, and the fifth signal is a new signal sent by device A for perception measurement, and the target device performs subsequent perception measurement based on the fifth signal;

After device A or the perception network function sends a switching command to the target device, device A continues to send the first signal, and the target device performs perception measurement based on the first signal. When 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 value), 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. Among them, the first signal is the signal sent by the original device A to device B for perception measurement, and the signal sent by device A to the target device for switching measurement (that is, the first signal and the second signal are the same signal), and the target device reuses the signal for subsequent perception measurement.

Among them, the first signal is the signal sent by the original device A to device B for perception measurement, and the fourth signal is the signal sent by the target device to device B for switching measurement. The target device reuses the signal for subsequent perception measurement;

After device B or the perception network function sends a switching command to the target device, it notifies device A to end the perception measurement operation, and device A stops sending the first signal to release 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. Among them, the first signal is the signal sent by the original device A and received by device B for perception measurement, and the fifth signal is a new signal sent by the target device for perception measurement. The target device performs subsequent perception measurement based on the fifth signal;

After device B or the perception network function sends a switching command to the target device, device B performs perception measurement 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 indicator or communication-related indicator exceeds a preset threshold value), device B or the perception network function notifies device A to end the perception measurement operation, and device A stops sending the first signal to release the occupied resources. Among them, the first signal is the signal sent by the original device A to device B for perception measurement, and the fourth signal is the signal sent by the target device to device B for switching measurement. The target device reuses the signal for subsequent perception measurement;

After device B or the perception network function sends a switching command to the target device, the target device sends a fifth signal, and device B performs perception measurement 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 indicator or communication-related indicator exceeds a preset threshold value), device B or the perception network function notifies device A to end the perception measurement operation, and device A stops sending the first signal to release the occupied resources.

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

Step 1: Trigger the measurement.

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).

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

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

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;

The preset threshold may be associated with a 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;

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 a bistatic distance d_bi (d_bi=d1+d2) obtained based on the measurement of the second signal is less than a preset threshold;

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 a distance from a perception target to device A obtained based on the first signal, or a distance from a perception target to device B, or the sum of a distance from a perception target to device A and a distance to device B.

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

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

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 value of the measurement quantity/indicator measured multiple times in succession meets the preset conditions, thereby avoiding the randomness/ping-pong effect brought about by judging based on a single result.

If the second device is a terminal, it also includes status information of the terminal.

Step 3: Switch judgment.

The perception network function decides whether to initiate a handover based on the handover measurement report reported by the second device.

If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, to still perform the perception measurement based on the first signal sent by device A and received by device B, or to stop the perception measurement.

If a handover is initiated, the perception network function determines the second device and sends a handover request message to it, and the handover request message is defined the same as in the first embodiment.

Step 4: Perform the switch.

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

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

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

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;

After receiving the switching 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 a device for performing perception measurement after switching. The perception network function sends a switching command to the target device to notify the target device to perform perception measurement;

Specifically, the following situations are included:

Among them, the first signal is the signal sent by the original 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 switching measurement. The target device reuses the signal for subsequent perception measurement;

Among them, 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 for perception measurement sent by the first target device to the second target device, and the target device performs subsequent perception measurement based on the third signal;

After the perception network function sends a switching 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. When 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 value), the perception network function notifies device A and device B to end the perception measurement operation, and device A stops sending the first signal to release the occupied resources. Among them, the first signal is the signal sent by the original 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 switching measurement. The target device reuses the signal for subsequent perception measurement;

After the perception network function sends a switching 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 measurement.
