1. General sense integration:

Future mobile communication systems, such as B5G systems or 6G systems, will have a sensing capability in addition to the communication capability. The sensing capability, i.e. one or more devices with sensing capability, can sense information such as the azimuth, distance, speed and the like of the target object through sending and receiving wireless signals, or detect, track, identify, image and the like the target object, event or environment. In the future, along with deployment of small base stations with high-frequency band and large bandwidth capabilities such as millimeter waves and terahertz waves in a 6G network, the perceived resolution is obviously improved compared with the centimeter waves, so that the 6G network can provide finer perceived services. Typical perceptual functions and application scenarios are shown in table 1.

TABLE 1

Communication perception integration, namely through frequency spectrum sharing and hardware sharing in the same system, realizes communication, perception function integration design, and the system can perceive information such as position, distance, speed when carrying out information transfer, detects, tracks, discerns target equipment or incident, and communication system supplements with perception system, realizes promotion in the aspect of overall performance and brings better service experience.

Integration of communication and radar belongs to a typical communication perception integration (communication perception fusion) application, and in the past, a radar system and a communication system are strictly distinguished due to different research objects and focus, and the two systems are independently researched in most scenes. In fact, radar is the same as a communication system as a typical way of information transmission, acquisition, processing and exchange, regardless of the principle of operation or the architecture of the system and the frequency band, there are many similarities. The communication and radar integrated design has great feasibility, and mainly realizes the following aspects: firstly, the communication system and the perception system are based on electromagnetic wave theory, and the information acquisition and transmission are completed by utilizing the emission and the reception of electromagnetic waves; secondly, the communication system and the perception system are provided with structures such as an antenna, a transmitting end, a receiving end, a signal processor and the like, and the structures have great overlapping on hardware resources; along with the development of technology, the two materials are increasingly overlapped on the working frequency band; in addition, the key technologies of signal modulation, reception detection, waveform design and the like have similarity. The integration of communication with radar systems can provide a number of advantages such as cost savings, reduced size, reduced power consumption, improved spectral efficiency, reduced mutual interference, etc., thereby improving overall system performance.

The following 6 kinds of sensing links are divided according to the difference between the sensing signal transmitting node and the receiving node, as shown in fig. 2. It should be noted that, in fig. 2, each sensing link is taken as an example of a transmitting node and a receiving node, in an actual system, different sensing links may be selected according to different sensing requirements, one or more transmitting nodes and receiving nodes of each sensing link may be provided, and the actual sensing system may include a plurality of different sensing links. The perceptions in fig. 2 take people and vehicles as examples, and the perceptions of the actual system will be richer.

1) And (5) sensing echo of the base station. In this way, the base station transmits a sensing signal and obtains a sensing result by receiving an echo of the sensing signal.

2) And perceiving an air interface between base stations. At this time, the base station 2 receives the sensing signal transmitted from the base station 1, and obtains a sensing result.

3) And sensing an uplink air interface. At this time, the base station receives a sensing signal transmitted from the terminal (UE) and obtains a sensing result.

4) And sensing a downlink air interface. At this time, the UE receives a sensing signal sent by the base station, and obtains a sensing result.

5) And (5) terminal echo sensing. At this time, the UE transmits a sensing signal and obtains a sensing result by receiving an echo of the sensing signal.

6) The inter-terminal direct link (Sidelink) perceives. For example, UE 2 receives the sensing signal sent by UE 1, and obtains the sensing result.

2. Bistatic radar:

The radar can be divided into a single-base radar and a double/multi-base radar according to whether a transmitter and a receiver are separated, and the double-base radar generally requires a far distance between a transmitting antenna and a receiving antenna, which is comparable to the radar in working distance. The external radiation source radar is a special case of a bistatic radar, and utilizes related electromagnetic wave detection theory technology and signal processing technology to acquire non-cooperative electromagnetic signals emitted by a third party (such as a communication base station) so as to realize detection, positioning, tracking and identification of a target, which is also called passive radar, bistatic/multistatic passive radar, non-cooperative irradiation source radar or non-cooperative passive detection system.

Bistatic radar sensing result computation typically requires the basis of a reference channel (direct path) signal and a supervisory channel (reflected path) signal, as shown in fig. 3. Taking the distance and Doppler calculation as an example, the measured distance of the bistatic radar is (R _T+R_R)＝2a＝cΔτ_rt+L＝cΔτ_t, namely, the target position is determined to be a certain point on an ellipsoid, wherein c is the speed of light, deltaτ _rt is the time difference between receiving a direct path signal and a target reflected path signal, deltaτ _t is the absolute time delay corresponding to the target reflected path (suitable for the condition of receiving and transmitting clock synchronization), R _T is the distance from a transmitting end to the target, L is the baseline distance, and theta _R is the observation angle of a receiving end, and Doppler shift of the bistatic radar due to the target motion can be expressed as follows

Wherein λ is a wavelength, f _c is a center frequency point, β is a bistatic angle, v is a moving speed of the target object, δ is an included angle between a moving direction of the target object and a bistatic horizon, and R _R is a distance from the target object to the receiving end.

The measurement method provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 4, a measurement method according to an embodiment of the present application includes:

In step 401, the first device acquires measurement instruction information and repeated transmission information of the first data.

Here, the first data is repeatedly transmitted data, and the repeated transmission information is used to indicate how the first data is repeatedly transmitted. The measurement indication information is used to indicate how to measure based on the first data. In this step, the first device may receive the measurement instruction information and the retransmission information sent by the second device, or may use the measurement instruction information and the retransmission information that are defined or configured in advance. The second device is a transmitting device of the first data.

In step 402, the first device measures a plurality of repeated transmission signals carrying the first data according to the measurement indication information and the repeated transmission information.

In this step, the first device performs measurement on a plurality of repeated transmission signals carrying the first data according to the measurement instruction information and the repeated transmission information acquired in step 401.

Thus, according to step 401 and step 402, the first device can obtain the measurement instruction information and the repeated transmission information of the first data, and further realize the measurement of the multiple repeated transmission signals carrying the first data according to the measurement instruction information and the repeated transmission information. Since the first data is the data of repeated transmission, the measurement based on a plurality of repeated transmission signals carrying the first data can overcome the influence of non-ideal factors such as timing and frequency deviation caused by the difference of receiving and transmitting clocks, and a reliable measurement result can be obtained.

Here, since the transmitting direction Of the first signal is the Line Of Sight (LOS) direction between the second device and the first device, and the transmitting direction Of the second signal is the non-Line Of Sight (NLOS) direction between the second device and the first device, measurement is performed based on the first signal and the second information, so that after the first information is subsequently sent to the third device, the third device can determine the sensing result according to the first information, and the quasi-determination Of the sensing result is improved.

In particular, it is agreed which transmission or transmissions are the first signal and which transmission or transmissions are the second signal, for example, default that the first transmission is the first signal, the last transmission is the second signal, or when the number of repeated transmissions N is even, default that the first N/2 transmission is the first signal, the last N/2 transmission is the second signal, or default that the odd transmission is the first signal, and the even transmission is the second signal.

In particular, the (sensing) measurement identification indication in the measurement indication information does not carry out (sensing) measurement based on the repeated transmission signal, the measurement indication information does not need to contain measurement signal resource information, measurement quantity, reporting configuration and measurement auxiliary information, and the first equipment only receives the repeated transmission signal sent by the second equipment based on the repeated transmission information and does not carry out measurement and reporting.

The doppler/velocity, the time/distance resolution, the maximum unambiguous doppler/velocity, the maximum unambiguous time/distance, etc. may be derived from a sensing requirement, which may be from a sensing network function, for example, the sensing network function sends the sensing requirement to the second device.

Further optionally, in this embodiment, the method further includes:

In this way, the first device sends the second information, and when the second information is the position information of the first device, the signal sending end is ensured to be capable of sending a valid first signal; when the second information is channel state information of the first equipment and the second equipment, the first equipment which is suitable for executing measurement is selected, and the acquisition and quality of the first information are ensured. As one embodiment, the first device sends the second information to the second device. Of course, the second information may be transmitted to the third device.

Wherein the location information of the first device may be location coordinates, distance, angle, etc. with respect to the transmitting device of the first signal/second signal, i.e. the second device.

Wherein the channel state information of the first device and the second device (which may be a third device) includes whether an LOS link is present. As an embodiment, the method for determining LOS may be: knowing the distance L or the position of the transceiver, judging whether an LOS path exists according to the measured time delay and the measured L by adopting an RTT mode.

That is, when the first condition is satisfied, the first device transmits retransmission stop instruction information to the second device, so that the second device stops repeating transmission of the first data.

If the first condition includes a threshold of performance index requirement, the condition that the first condition is satisfied may be that the performance index in the measured performance index information reaches the threshold of corresponding performance index requirement, where the threshold of performance index requirement is predefined or preconfigured, or the second device sends the threshold of performance index requirement to the first device. If the first condition includes that the data of the repeated transmission is decoded correctly, the first condition is met, or the first device can recover the first data through decoding after receiving the repeated transmission signal; if the first condition includes a threshold required by the number of repeated transmissions, the condition that the first condition is satisfied may also be that the number of repeated transmissions reaches the threshold required by the number of repeated transmissions, where the threshold required by the number of repeated transmissions is predefined or preconfigured, or the second device sends the threshold required by the number of repeated transmissions to the first device.

Further, optionally, in this embodiment, the first device measures, according to the measurement instruction information, a first signal and a second signal in the repeated transmission signal, to obtain the first information, including:

the first device obtains first channel information according to the first data and the first signal;

the first device obtains second channel information according to the first data and the second signal;

The first device obtains the first information according to the first channel information and the second channel information.

That is, after the first device receives the retransmission information (including the first signal and the second signal), the first device may obtain the first information in a manner that: and obtaining first channel information according to the first data and the first signal, obtaining second channel information according to the first data and the second signal, and obtaining first information according to the first channel information and the second channel information. Here, the first data is data recovered by the first device after receiving the repeated transmission signal, demodulating and decoding based on the repeated transmission signal.

For example, the repeated transmission signal contains a data signal, and the receiving end is unknown, so that the data reconstruction of the transmitting end and then the perception measurement are needed. In the repeated transmission signals, a first signal (reference channel signal) and a second signal (monitoring channel signal) are subjected to beam forming by using different beam forming vectors, the first signal is sent by using a beam pointing to the direction of a first device, the second signal is sent by using a beam pointing to a sensing area, after the repeated transmission signals (including the first signal and/or the second signal) are received by the first device, demodulation and decoding are carried out on the basis of the repeated transmission signals, transmission data (first data) is restored, channel estimation is carried out on the basis of the transmission data and the first signal to obtain channel response information H1 (first channel information), channel estimation is carried out on the basis of the transmission data and the second signal to obtain channel response information H2 (second channel information), and further, the first information is obtained according to the channel response information.

Here, assuming that the time-frequency domain resources corresponding to the first signal and the second signal are N OFDM symbols and M subcarriers, the H1 and H2 matrix sizes are m×n (row corresponds to the time domain and column corresponds to the frequency domain). Assuming that a single moving target exists in the target sensing area, performing IFFT calculation along the frequency domain dimension according to H1 to obtain reference channel time delay domain information (taking a single OFDM symbol as an example), wherein the time delay value of the strongest path/first arrival path of the first signal is τ1=20.35 (ns); according to H2, performing IFFT calculation along the frequency domain dimension to obtain reference channel delay domain information (taking a single OFDM symbol as an example), where the delay value of the strongest path of the second signal is τ2=315.4 (ns); the delay difference between the first signal strongest path/first-reach path and the second signal strongest path is Δτ= 295.05 (ns). It should be noted that, the quantization result reported by the first device may be the quantization result of the actual delay information, or may be an index value corresponding to a path (the strongest path or a path with strength exceeding a preset threshold) that satisfies the condition after performing IFFT along the frequency domain.

Similarly, according to H1, performing DFT/FFT computation along the time domain dimension to obtain reference channel doppler domain information (taking a single subcarrier as an example), where the doppler shift value of the strongest path/first arrival path of the first signal is 26.67 (Hz); according to H2, carrying out IDFT/IFFT calculation along the frequency domain dimension to obtain reference channel time delay domain information (taking a single subcarrier as an example), wherein the Doppler frequency shift value of the strongest path of the second signal is 315.4 (Hz); the doppler shift difference between the first signal strongest path/first-arrival path and the second signal strongest path is 288.73 (Hz). It should be noted that, the quantization result of the real doppler information may be reported by the first device, or may be an index value corresponding to a path (a strongest path or a path with strength exceeding a preset threshold) that satisfies a condition after DFT/FFT is performed along a time domain dimension.

Similar to the calculation of angle information (multiple receiving antennas), based on channel information H1 and H2 of different antennas, the angle information can be obtained by performing calculation through DFT/FFT operation along the antenna dimension or a MUSIC and other super-resolution algorithms, such as the arrival angle of the strongest path/first arrival path of the first signal is 0.9 degrees; the arrival angle of the strongest path of the second signal is 58.2 degrees; the difference in arrival angle between the first signal strongest path/first arrival path and the second signal strongest path is 57.3. It can be understood that the angle information calculated here is angle information in a local coordinate system of the receiver, and the angle information in the first information may be angle information in the local coordinate system or angle information converted into angle information in a global coordinate system.

Or based on two-dimensional DFT/FFT operation on H1 and H2 to obtain delay-Doppler domain information, and further obtain delay and Doppler measurement results in the first information; or based on three-dimensional DFT/FFT operation on H1 and H2, obtaining time delay-Doppler-angle domain information, and further obtaining time delay, doppler and angle measurement results in the first information.

Further, the sum of the distance of the target object relative to the first device (receiver) and the distance relative to the second device (transmitter), and the distance of the transceiver can be further reduced, which can be calculated according to the time delay information (the time difference Δτ between the arrival of the first signal and the arrival of the second signal): r _T+R_R -l= Δτ c (c is the speed of light); the target object distance relative to the receiver can be calculated from the time delay and angle information: and thetar is the angle of the target object relative to the receiver.

Knowing the departure angles of the first signal and the second signal, combining the arrival angles of the first signal and the second signal can further calculate a bistatic angle beta; according to the bistatic angle and Doppler shift and formulasThe velocity v x cos delta of the target object relative to the bistatic horizon can be calculated. Further, the actual movement velocity v of the target object can be further obtained according to the prior information of the movement direction of the target or by obtaining the movement direction information of the target through multiple measurements.

It should be noted that this type is merely illustrative, and the specific calculation method used is not limited.

On the other hand, optionally, in this embodiment, the first device measures, according to the measurement instruction information, a first signal and a second signal in the repeated transmission signal, to obtain the first information, including:

The first device obtains third channel information through the cross-correlation operation of the first signal and the second signal;

and the first device obtains the first information according to the third channel information.

That is, after the first device receives the retransmission information (including the first signal and the second signal), the second manner of obtaining the first information may be: and obtaining third channel information through the cross-correlation operation of the first signal and the second signal, and further obtaining first information according to the third channel information.

At this time, the first signal and the second signal used for the cross-correlation operation have the same corresponding data content (i.e., the symbol sequences obtained after the originating processing such as code modulation are the same), that is, the scrambling sequences and/or redundancy version numbers of the first signal and the second signal used for the cross-correlation operation are required to be the same. Namely, when the (perception) measurement identification in the measurement indication information indicates (perception) measurement based on the repeated transmission signal, the scrambling sequence and/or redundancy version number of the second signal in the repeated transmission signal are identical to those of the first signal, the first information is obtained in a second mode; or when the (perception) measurement identification in the measurement indication information indicates that (perception) measurement is performed based on the repeated transmission signal, the scrambling sequence and/or the redundancy version number of the repeated transmission signal are/is the same as each other, and the first information is obtained in the second mode. The scrambling sequence and/or redundancy version number of the second signal is the same as that of the first signal, and may be the same as that of the first signal (for example, the first signal with the closest time domain transmission resource) with the smallest repeated transmission interval relative to the second signal.

For example, the repeated transmission signal contains a data signal, the receiving end is unknown, and the channel information can be obtained by performing a cross-correlation operation on the first signal and the second signal, so that the data at the transmitting end does not need to be restored through demodulation and/or decoding. In the repeated transmission signals, the first signal (reference channel signal) and the second signal (monitoring channel signal) are subjected to beam forming by using different beam forming vectors, the first signal is sent by using a beam pointing to the direction of the first device, the second signal is sent by using a beam pointing to the sensing area, after the first device receives the repeated transmission signals (including the first signal and/or the second signal), the cross-correlation operation result of the first signal and the second signal is calculated, specifically, the received first signal is assumed to be R1 (k, l), wherein k is a frequency domain sampling point index (such as a subcarrier index), and l is a time domain sampling point index (e.g. OFDM symbol index), the received second signal is R2 (k, l), the time-frequency domain resources corresponding to the first signal and the second signal are assumed to be N OFDM symbols and M subcarriers, and the cross-correlation operation between the first signal and the second signal may be dividing (R2 (k, l)/R1 (k, l)) or conjugate multiplying (R2 (k, l) x conj (R1 (k, l)) by conj () to obtain a third channel information matrix H3, where the H3 matrix size is M x N (row corresponds to time domain and column corresponds to frequency domain).

Here, assuming that a single moving target exists in the target sensing area, according to H3, IDFT/IFFT calculation along the frequency domain dimension may obtain reference channel delay domain information (taking a single OFDM symbol as an example), where a delay value in the first information reported by the first device is 295.1 (ns) (a delay value of a strongest path corresponding to H3 or a path with strength exceeding a preset threshold). It should be noted that, the quantization result of the real delay information may be reported by the first device, or may be an index value corresponding to a path (a strongest path or a path with strength exceeding a preset threshold) that satisfies a condition after IDFT/IFFT is performed along the frequency domain.

Similarly, according to H3, reference channel doppler domain information (for example, a single subcarrier) may be obtained by performing DFT/FFT calculation along the time domain dimension, where the doppler shift value in the first information reported by the first device is 293.3 (Hz) (the strongest path corresponding to H3 or the doppler shift value with intensity exceeding the preset threshold path).
