In addition, by calculating the perception result based on the measurement results of the two devices, perception measurement of passive targets can be achieved, thereby improving perception performance, and perception measurement can also be multiplexed with ranging signals to save signal transmission overhead.

T +R R -L=c·Δτ, where R T is the distance from the signal sending device (such as the first device) to the sensing target, R Ris the distance from the sensing target to the signal receiving device (such as the second device), and L is the distance between the first device and the second device (baseline distance). If the baseline distance L is known, the distance from the first device to the sensing target and the sensing target to the second device and R can be further calculated. T +R R .

R (horizontal arrival angle information), and the above distance difference information, the distance between the perceived target and the second device can be obtained, which can be expressed as follows:

[0122] For example, the distance R between the sensing target and the second device can be R , arrival angle information θ R , the coordinate information (x0, y0) of the perception target relative to the local coordinate system of the second device can be calculated.

[0123] If three-dimensional space is considered, the arrival angle information θ obtained by measuring the received signal can be used to R1 (horizontal arrival angle information), arrival angle information θ R2 (vertical arrival angle information), and the above distance difference information, the distance between the perceived target and the second device is obtained, which can be expressed as follows:

[0124] For example, the distance R between the sensing target and the second device can be R , arrival angle information θ R1 and θ R2 , the coordinate information (x0, y0, z0) of the perception target relative to the local coordinate system of the second device can be calculated.

[0125] In the above scenario, the sum of the distances R from the perceived target to the first device and the second device can be calculated based on the baseline distance L. T +R R , the distance R from the perceived target to the first device T , the distance R from the target to the second device R , and the location coordinates of the perception target. In some embodiments, the first device and the second device measure the baseline distance L using RTT, while simultaneously performing perception-related measurements such as perception target positioning or ranging. During the measurement process, the ranging signal can be multiplexed as a reference channel signal (such as a direct path signal) in the perception measurement.

[0126] It should be noted that FIG4 is only an example of a scenario, and the embodiments of the present application are not limited to specific application scenarios.

[0127] As an optional implementation manner, the first measurement result includes:

[0128] The arrival time of the first signal.

[0129] The first device can directly calculate the distance between the first device and the second device through the arrival time of the above-mentioned first signal, and can calculate the perception result based on the distance, so that the perception result or ranging result can be simply and quickly calculated through the arrival time of the above-mentioned first signal.

[0130] As an optional implementation, the measurement signal includes a second signal, and the second signal is used to measure the distance between the first device and the second device.

[0131] The distance between the first device and the second device may be referred to as a baseline distance.

[0132] After the distance between the first device and the second device is determined in this way, the passive target can be sensed or measured, for example, as shown in FIG4 , based on multiple distances or sensed results of the distance between the first device and the second device.

[0133] Optionally, when the measurement signal includes only the second signal, the measurement signal is used for sensing measurement and ranging, and the second signal is a signal sent omnidirectionally, or the second signal is a signal sent using a wide beam; or,

[0134] In a case where the measurement signal further includes a third signal, the second signal is used for sensing measurement and ranging, the third signal is used for sensing measurement, the beam direction of the second signal is the direction pointing to the second device, and the beam direction of the third signal is the direction corresponding to the area to be sensed; or

[0135] In the case where the measurement signal also includes a third signal and a fourth signal, the third signal is used for perception measurement, the fourth signal is used for perception measurement, the beam directions of the second signal and the third signal are in the direction pointing to the second device, and the beam direction of the fourth signal is the direction corresponding to the area to be perceived.

[0136] Among them, when the above-mentioned second signal is used for perception measurement and ranging, ranging measurement can be multiplexed with the perception measurement signal, or perception measurement can be multiplexed with the ranging signal. Specifically, the two measurements are implemented through one signal, thereby saving transmission overhead.

[0137] The above-mentioned area to be sensed is the area where the sensing target is located.

[0138] In the above embodiment, since the beam direction of the second signal is the direction pointing to the second device, and the beam direction of the third signal is the direction corresponding to the area to be sensed, it is possible to send signals in different directions so that the perception measurement result is more accurate. The second device can measure the arrival time difference of the second signal and the third signal, and can also calculate the distance difference information (such as R T +R R -L), and calculate angle information, such as the arrival angle of the second signal, the arrival angle of the third signal, and the difference between the arrival angles of the second signal and the third signal.

[0139] In the above embodiment, since the measurement signal only includes the second signal, this can save transmission overhead, and since the second signal is an omnidirectional signal transmitted using a wide beam, this allows the second device to calculate the arrival time difference based on the second signal, such as the delay difference between the strongest path / first arrival path of the second signal and other signal paths, and for example: the delay difference between the strongest path / first arrival path of the first signal and at least one path among other signal paths whose strength exceeds a preset threshold, and the distance difference information (R T +R R -L); and calculating angle information, such as the arrival angle of at least one signal path in the second signal, or the difference in arrival angle between two paths.

[0140] In the above embodiment, since the measurement signal includes the second signal, the third signal and the fourth signal, the second device can calculate more usable information to further improve the reliability of the measurement. For example, the second device can calculate the arrival time difference corresponding to the third signal and the fourth signal, and the distance difference information (R T +R R -L); and calculating angle information, such as the arrival angle of the third signal, the arrival angle of the fourth signal, and the difference between the arrival angles of the third signal and the fourth signal.

[0141] In some embodiments, when the measurement signal includes the second signal, the third signal, and the fourth signal, the second signal and the third signal may be sent using the same beam or the same spatial filter coefficient, thereby improving the correlation between the measurement results of the second signal and the third signal, and facilitating improving the accuracy of the final measurement result.

[0142] In some embodiments, at least one of the first signal, the second signal, the third signal, and the fourth signal is the following signal:

[0143] Communication reference signal, synchronization signal, perception signal or communication data signal.

[0144] Among them, the above-mentioned communication reference signal can be a channel state information reference signal (CSI-RS), a physical downlink shared channel (PDSCH) demodulation reference signal (DMRS) or a positioning reference signal (PRS), etc.

[0145] The synchronization signal may be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS).

[0146] The above-mentioned perception signal may be a perception signal designed based on a Gold sequence or a ZC sequence, or a perception signal designed based on a Frequency Modulated Continuous Wave (FMCW), etc.

[0147] The communication data signal is a signal that carries communication data information.

[0148] The first signal, second signal, third signal and fourth signal may be the same signal or different signals, which is not limited.

[0149] In some embodiments, at least two of the second signal, the third signal, and the fourth signal are time-division multiplexed, frequency-division multiplexed, or code-division multiplexed.

[0150] In some embodiments, when the second signal is used only for ranging, the second signal is a subset of the third signal. For example, if the transmission resource corresponding to the third signal includes multiple time domain symbols, the third signal on one of the time domain symbols can be used as the second signal, thereby realizing ranging multiplexing perception signals to save signal management overhead.

[0151] In some embodiments, when transmission resources of the first, second, third, and fourth signals belong to the same frequency band, the timing advances (TAs) corresponding to the first, second, third, and fourth signals belong to the same timing advance group (TAG). Because the TAs corresponding to the first, second, third, and fourth signals belong to the same TAG, measurements performed using these signals can avoid signal timing inaccuracies, thereby improving measurement accuracy.

[0152] As an optional implementation, the method further includes:

[0153] The first device receives the second measurement result sent by the second device.

[0154] In some implementations, the second measurement result may be received by the first device from a third device, such as sent by the second device to the third device, and the third device decides to send the second measurement result to the first device.

[0155] As an optional implementation manner, the second measurement result includes ranging related result information; or

[0156] The second measurement result includes: ranging related result information and perception measurement related result information.

[0161] The above-mentioned arrival time information is the arrival time information of the measurement signal, which is used to calculate the distance. That is, the distance-related information can be reflected through the arrival time information, so the above-mentioned distance measurement-related result information can include the above-mentioned arrival time information.

[0162] Since the above-mentioned second measurement result includes at least one of the ranging-related result information and the perception measurement-related result information, this enables the first device to calculate the above-mentioned perception result or ranging result based on the more measurement results, which is conducive to improving the accuracy of the perception result or ranging result.

[0163] In some embodiments, the above-mentioned ranging-related result information is not limited to the above-mentioned arrival time information. For example, it can also be the distance between the first device and the second device, such as the sending time of the measurement signal sent by the first device to the second device, so that the second device can calculate the distance between the first device and the second device based on the arrival time information.

[0164] Optionally, the arrival time information includes at least one of the following:

[0168] The strongest path may be a signal path with the largest signal strength or receiving power.

[0169] The time delay information of the strongest path of the measurement signal may include the time delay information of the strongest path of at least one of the second signal, the third signal and the fourth signal.

[0170] The delay information of the first arrival path of the measurement signal may include the delay information of the first arrival path of at least one of the second signal, the third signal and the fourth signal.

[0171] The delay information of the signal path where the strength of the measured signal exceeds the first threshold may include the delay information of the signal path where the strength of at least one of the second signal, the third signal, and the fourth signal exceeds the first threshold. The first threshold may be a protocol agreement or a network-side configuration.

[0173] In this implementation, since only the delay information of the strongest path, the first-reaching path, or the signal path whose strength exceeds the first threshold is required, the measurement result reporting overhead can be used.

[0174] Optionally, the delay information included in the perception measurement-related result information includes at least one of the following:

[0175] First arrival time difference information, second arrival time difference information, and third arrival time difference information; wherein, the first arrival time difference information includes the arrival time difference information of the second signal and the third signal, the second arrival time difference information includes the arrival time difference of multiple signal paths of the second signal, and the third arrival time difference information includes the arrival time difference information of the third signal and the fourth signal.

[0176] The above-mentioned multiple signal paths of the second signal can be the arrival time difference information of the multiple signal paths of the second signal when the measurement signal only includes the second signal, such as the delay difference between the strongest path / first arrival path of the second signal and other signal paths, such as the delay difference between the strongest path / first arrival path of the first signal and at least one path among the other signal paths whose strength exceeds a preset threshold.

[0177] The first device may calculate a perception result or a ranging result based on the arrival time difference information to improve the reliability of the perception result or the ranging result.

[0182] The time delay difference information between the first path of the second signal and the signal path of the third signal that meets the first condition.

[0183] The first condition is agreed upon in the protocol or configured on the network side. For example, the first condition includes at least one of the following:

[0184] The strength of the signal path exceeds the second threshold;

[0190] The angular difference between the signal path and the first arrival path is within a sixth interval.

[0191] The above thresholds and interval ranges are agreed upon in the protocol or configured on the network side.

[0192] In the above implementation, since only the delay difference information between signal paths needs to be reported, the measurement result reporting overhead can be saved.

[0193] In some embodiments, the arrival time difference information of the third signal and the fourth signal may include at least one of the following:

[0198] Among them, the above-mentioned first condition refers to the corresponding description of the above-mentioned embodiment and is not repeated here.

[0199] In the above implementation, since only the delay difference information between signal paths needs to be reported, the measurement result reporting overhead can be saved.

[0205] The distance difference information calculated based on the arrival time difference information may be distance difference information calculated based on the arrival time difference information and the speed of the signal.

[0206] In the above embodiment, since the measurement result includes the distance difference information, the arrival time information does not need to be reported, thereby saving the measurement result reporting overhead.

[0216] The above angle information may be a specific angle value or an angle range.

[0217] The first device can calculate the distance from the perceived target to the second device based on the above angle information, and can also be used to calculate the distance from the perceived target to the first device, etc.

[0218] As an optional implementation, the method further includes:

[0246] Alternatively, the perception service type 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 intensity perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc.

[0265] Frequency domain resource spacing, which indicates the spacing between adjacent signal frequency domain resource units, can be expressed as the number of REs or RBs, or as a density value (Density). For example, Density = 1 means 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 OFDM systems, when subcarriers are continuously mapped, the frequency domain spacing is equal to the subcarrier spacing.

[0266] The time domain resource interval is 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.

[0282] In some embodiments, the time information of the first signal may not be received. For example, the second device sends the first signal immediately after receiving the measurement signal, so that the first device can predict the sending time of the first signal based on the arrival time of the measurement signal or the sending time of the measurement signal.

[0283] In an embodiment of the present application, a first device sends a measurement signal to a second device, the measurement signal being used for ranging.

In this way, the first device calculates at least one of a perception result and a ranging result based on the first measurement result of the first device and the second measurement result of the second device. Alternatively, by sending the first measurement result to the third device, the third device calculates at least one of a perception result and a ranging result based on the measurement results of the two devices. This allows for calculation of at least one of a perception result and a ranging result based on the measurement results of the two devices when the distance between the devices is unknown, thereby improving device measurement performance.

[0429] The following describes the method provided in the embodiments of the present application through multiple examples:

[0430] Example 1:

[0431] In this embodiment, a first device sends a measurement signal (including a perception signal or a first ranging signal) to a second device. The second device performs a measurement to obtain a first measurement result and sends it to the first device. The second device then sends a second ranging signal (i.e., the first signal) to the first device. The first device then performs a measurement and calculates a perception result or ranging result based on the measurement result sent by the second device. In this embodiment, for RTT ranging, the ranging signal needs to be sent back and forth. The ranging signal sent first is called the first ranging signal, and the signal sent second is called the second ranging signal.

[0432] In this embodiment, the sensing signal and the first ranging signal are jointly transmitted or multiplexed, and the first device calculates the sensing result or the ranging result. The specific process is as follows:

[0433] Step 1: The first device sends a first request message to the second device. The first request message includes at least one of the following:

[0434] A perception measurement request, i.e., a request for ranging or positioning at least one perception target in an environment; optionally, since the perception target ranging or positioning requires measuring the distance between devices, the perception measurement request includes a device ranging request by default;

[0435] The device distance measurement request is to measure the distance between the first device and the second device.

[0436] Step 2: The second device receives the first request information sent by the first device, and (optionally) sends a first response information to the first device, confirming participation in the perception measurement or device ranging initiated by the first device.

[0437] Step 3: The first device sends a signal to the second device according to the signal configuration information, including the following situations:

[0438] Case 1: The first device sends a second signal and a third signal to the second device based on the second signal configuration information and the third signal configuration information, where the second signal is a signal used for device ranging and perception (i.e., the second signal serves as both a perception signal and a first ranging signal), and the third signal is a signal used for perception. The second and third signals are sent using different beams (spatial filter coefficients), with the second signal's beam direction being the LOS direction (i.e., directed toward the second device), and the third signal's beam direction being the direction corresponding to the area to be perceived (i.e., directed toward the perception target).

[0439] Case 2: The first device sends a second signal to the second device according to the second signal configuration information, where the second signal is a signal used for device ranging and perception (i.e., the second signal serves as both the perception signal and the first ranging signal). The second signal is an omnidirectional signal or a signal sent using a wide beam.

[0440] Case 3: The first device sends the second signal, the third signal, and the fourth signal to the second device according to the second signal configuration information, the third signal configuration information, and the fourth signal configuration information, wherein the second signal is a signal for device ranging, and the third signal and the fourth signal are signals for perception. The second signal and the third signal are sent using the same beam (spatial filter coefficient), and the fourth signal is sent using a different beam. The beam directions of the second and third signals are LOS directions (i.e., pointing to the second device), and the beam direction of the fourth signal is the direction corresponding to the area to be sensed (i.e., pointing to the perception target).

[0453] In this embodiment, each item in the indication information may be sent in the same signaling or in different signalings.

[0458] Corresponding to the above situation 2: the arrival time difference calculated based on the second signal (specifically, it can be the delay difference between the second signal's strongest path / first arrival path and other signal paths, such as the delay difference between the second signal's strongest path / first arrival path and at least one path whose strength exceeds a preset threshold among other signal paths); the distance difference information (R T +R R -L); angle information, such as the arrival angle of at least one signal path in the second signal, or the difference in arrival angle between two paths.

[0459] Corresponding to the above situation 3: the arrival time difference corresponding to the third signal and the fourth signal (specifically, it can be the delay difference between the strongest path / first arrival path of the third signal and the strongest path of the fourth signal, or the delay difference between the strongest path / first arrival path of the third signal and at least one path of the fourth signal that meets the preset conditions); the distance difference information (R T +R R -L); angle information, such as the arrival angle of the third signal, the arrival angle of the fourth signal, and the difference between the arrival angles of the third signal and the fourth signal.

[0462] The difference between the Doppler of the signal path and the Doppler of the first arrival path (LOS path) exceeds a preset threshold (eg, indicating that the reflecting target corresponding to the signal path is a target that meets certain motion characteristics).

[0463] Step 6: The second device sends the first signal (second ranging signal) to the first device according to the first signal configuration information, and the sending time T2 of the first signal or the time difference (T2-T1) between the sending time of the first signal and the arrival time of the second signal.

[0464] The first signal configuration information may be sent by the first device to the second device.

[0465] Step 7. The first device receives the first signal and measures it to obtain the arrival time T3 of the first signal, for example: the delay value of the strongest path / first arrival path of the first signal (relative to a specific moment, such as the delay value at the start of the downlink time slot / downlink subframe / uplink time slot / uplink subframe / radio frame), or the delay value of at least one path in which the strength of the path in the first signal exceeds a preset threshold.

[0474] Optionally, at least two of the second signal, the third signal, and the fourth signal are time-division multiplexed, frequency-division multiplexed, or code-division multiplexed.

[0475] Among them, if the second signal is only used for ranging (corresponding to the above situation 3), the second signal can be a subset of the third signal, that is, for example, the sending resource corresponding to the third signal contains multiple time domain symbols, then the third signal on one of the time domain symbols can be used as the second signal.

[0476] The first signal, the second signal, the third signal, and the fourth signal are transmitted in the same frequency band and belong to the same TAG.

[0477] Example 2:

[0478] In this embodiment, the first device sends a measurement signal (including a perception signal or a first ranging signal) to the second device, the second device performs measurement to obtain a first measurement result and sends it to the third device, the second device sends a second ranging signal (the above-mentioned first signal) to the first device, the first device performs measurement to obtain a second measurement result and sends it to the third device, and the third device calculates a perception result or a ranging result based on the first measurement result and the second measurement result.

[0479] In this embodiment, the sensing signal and the first ranging signal are jointly transmitted or multiplexed, and the third device initiates a demand and calculates the sensing result or the ranging result. The specific process is as follows:

[0485] Step 6: The second device receives the signal sent by the first device, performs measurement to obtain a measurement result (ie, the value of the measured quantity), and sends it to the third device. The content of the measurement result is the same as that in the first embodiment.

[0486] Step 7: The second device sends the first signal (second ranging signal) to the first device according to the first signal configuration information.

[0490] Step 10: The first device sends the arrival time T3 of the first signal to the third device, or the time difference between the arrival time of the first signal and the sending time of the second signal.

[0491] Step 11: The third device calculates and obtains the perception measurement and ranging results.

[0492] In an embodiment of the present application, a method for bistatic sensing and ranging is provided. A first device transmits a sensing signal or a first ranging signal to a second device. The second device performs a measurement to obtain a first measurement result and transmits it to the first device. The second device transmits a second ranging signal to the first device. The first device performs a measurement to obtain a second measurement result and calculates a sensing result or ranging result based on the first measurement result transmitted by the second device. Alternatively, the first and second devices feed their measurement results back to a third device, which then calculates the sensing result or ranging result. The first ranging signal can be multiplexed as a reference channel signal for bistatic sensing. This method can save signal resource and signaling overhead, ensuring bistatic sensing performance.
