For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

1. communication perception integration or communication perception integration.

Wireless communication and radar sensing have been evolving in parallel, but with limited intersections. They share much in terms of signal processing algorithms, devices, and to some extent system architecture. In recent years, these two systems have received increasing attention from researchers in coexistence, collaborative and joint designs.

In the early days, extensive research was conducted on the coexistence problem of communication systems and radar systems, and the research emphasis was on developing effective interference management techniques so that two systems deployed separately can operate smoothly without interfering with each other. While the radar and communication system may be co-located or even physically integrated, they transmit two different signals in the time/frequency domain. They share the same resources by co-operation to minimize interference that simultaneous operation is with each other. Corresponding measures include beamforming, cooperative spectrum sharing, primary and secondary spectrum sharing, dynamic coexistence, etc. However, effective interference cancellation generally places stringent requirements on mobility of nodes and information exchange between nodes, and thus the improvement of spectral efficiency is practically limited. Since interference in a co-existence system is caused by transmitting two independent signals, it is natural to ask if one transmitted signal can be used simultaneously for communication and radar sensing. Radar systems typically use specially designed waveforms, such as short pulses and chirps, to enable high power radiation and to simplify receiver processing. However, these waveforms are not necessary for radar detection, passive radar or passive sensing with different radio signals as the sensing signal is a good example.

Machine learning, and in particular deep learning techniques, further facilitate the potential of non-dedicated radio signals for radar sensing. With these technologies, conventional radars are moving toward more general wireless awareness. Wireless perception herein may refer broadly to retrieving information from a received radio signal, rather than modulating communication data to a signal at a transmitter. For wireless sensing related to the sensing target position, dynamic parameters such as target signal reflection time delay, angle of Arrival (AOA), angle of departure (Angle of Departure, AOD) and Doppler can be estimated through a common signal processing method; for sensing target physical characteristics this can be achieved by measuring the device, object or natural mode signal. The two sensing modes can be respectively called sensing parameter estimation and pattern recognition. In this sense, wireless sensing refers to more general sensing techniques and applications that use radio signals.

Communication awareness integration (Integrated Sensing and Communication, ISAC) has the potential to integrate wireless awareness into large-scale mobile networks, referred to herein as aware mobile networks (Perceptive Mobile Networks, PMNs). The PMN can be evolved from the current 5G mobile network, and is expected to become a ubiquitous wireless sensor network, and at the same time, stable high-quality mobile communication services are provided. It can be built on top of existing mobile network infrastructure without requiring significant changes to the network architecture and equipment. It will free up the maximum capability of the mobile network and avoid spending high infrastructure costs to build additional new wide area wireless sensor networks separately. As coverage expands, the integrated communication and sensing capabilities are expected to enable many new applications. A perceived mobile network is capable of providing both communication and wireless perceived services and, due to its large broadband coverage and powerful infrastructure, is likely to be a ubiquitous wireless sensing solution. The combined coordinated communication and sensing capability of the sensor network can improve the productivity of our society and is helpful for promoting the generation of a large number of new applications which cannot be effectively realized by the existing sensor network. Some early work with passive sensing using movement signals has demonstrated its potential. Such as traffic monitoring, weather forecast and remote sensing of rainfall based on radio signals of the global system for mobile communications (Global System for Mobile Communications, GSM). The perceived mobile network can be widely applied to communication and sensing in traffic, communication, energy, precision agriculture and security fields, and the existing solutions are either not feasible or inefficient. The sensor network can also provide complementary sensing capability for the existing sensor network, has unique day and night operation function, and can penetrate fog, leaves and even solid objects.

2. And (5) array radar.

Based on the sensing technology of phased array radar, the method has a mature hardware implementation scheme and a signal processing method at present. The phased array radar uses the whole array to carry out beam forming, can form high-gain and high-directivity narrow beams, and is beneficial to improving the perceived signal-to-noise ratio (Signal Noise Ratio, SNR). However, the beam width of the phased array radar determines the angular resolution, and when the sensing area is large, beam scanning is required, and multiple targets cannot be distinguished when the distance between the multiple targets is smaller than the beam width; the maximum number of detectable targets is limited.

MIMO radars transmit signals independently (quasi-orthogonal or orthogonal) from each other on different antennas, and the general beam is wider. Through reasonable deployment of antenna positions, a large-aperture virtual array can be formed under the condition of the same number of antennas, and the angle resolution is further improved. In addition, the MIMO radar has stronger clutter suppression capability. Quasi-orthogonal refers to that the transmitted signals of different transmitting antennas are not completely orthogonal, and have certain cross-correlation, but the cross-correlation is weaker. For example, if the cross-correlation is expressed by a correlation coefficient of <0.5, the cross-correlation is considered weak.

In future sense-of-general integrated scenes, sensing one or more targets or events in a certain area is often needed to sense based on sensing of radar technology, such as device-free positioning and track tracking of pedestrians, motor vehicles, unmanned aerial vehicles and the like, and before this, an area with larger angular coverage may also need to be detected first to identify an approximate area where the target is located. Different from the traditional radar scene, in the scene of the integrated sense of general, the service coverage distance is tens to hundreds of meters, the surrounding environment and objects easily form obvious clutters, and the perception performance is seriously affected. In the scene of integrated sense of general, multipath propagation of signals can increase capacity for communication, but is more complex for sensing, one part becomes cluttered, and the other part can also help to improve sensing performance.

A large part of future communication systems are MIMO systems, and sensing technology based on array radar is a great development trend. For simplicity, the MIMO-sense integrated system may be simply referred to as a MIMO-ISAC system. MIMO radars are widely used in the radar detection field, but in the communication perception integrated field, the antenna selection method of the MIMO-ISAC system and the corresponding adaptive method are not clear.

3. MIMO radar virtual array principle.

The improvement of the perceived accuracy of the MIMO-ISAC system also makes use of the concept of virtual arrays in MIMO radars, as briefly described below. Considering the total number of the MIMO radar transmitting array antennas as M, and the position coordinates of each transmitting antenna as x _T,m M=0, 1,..m-1, total number of receive array antennas N, each receive antenna coordinate x _R,n N=0, 1,..n-1. Assuming that the transmission signals of the transmission antennas are orthogonal,:

wherein s is _m (t) represents the transmission signal of the mth antenna, s _k (t) represents the transmission signal of the kth antenna, delta _mk Is a dirac function. At this time, the receiver separates the transmission signals using M matched filters for each reception antenna, so that the receiver obtains NM reception signals in total. Considering 1 far field point target, the target response obtained by the mth matched filter of the nth receive antenna can be expressed as:

Wherein u is _t Is 1 unit vector pointing from radar transmitter to point target, alpha ^(t) And lambda is the carrier frequency wavelength of the transmitted signal and is the reflection coefficient of the point target.

It can be seen that the phase of the reflected signal is determined jointly by the transmitting antenna and the receiving antenna. Equivalently, the target response of equation (2) is exactly the same as that obtained for an array with 1 antenna number NM, and equivalent array antenna position coordinates are:

{x _T,m +x _R,n |m＝0,1,...,M-1；n＝0,1,...,N-1} (3)

it should be appreciated that when the MIMO radar is actually deployed, by reasonably setting the positions of the transmitting array and/or the receiving array, an array including NM virtual antennas that do not overlap with each other can be constructed by only n+m physical antennas. Since virtual arrays have been able to form larger array apertures, better angular resolution can be achieved.

If there are L targets, it is assumed that there is a certain correlation between the signals sent by the transmitting antennas, and the received signal (where only the angle estimation is analyzed, and the delay and doppler parameters are assumed to be compensated at the receiver side) after the MIMO radar has undergone distance-doppler filtering is:

wherein alpha is _l For the first target reflectance and reflection delay, T ₀ To transmit the signal length, and a (θ) satisfies:

wherein, the liquid crystal display device comprises a liquid crystal display device,

s(t)＝[s ₁ (t),...,s _M (t)] ^T (8)

wherein A (θ) is an NxM MIMO radar steering vector matrix, equations (6) (7) are the receive and transmit array steering vectors, respectively, τ _T,m M=0, 1, M-1 and τ _R,n N=0, 1..n-1 is the signal propagation delay of the transmit and receive array, respectively, relative to the reference point. Each transmitting antenna transmits a signal correlation matrix as

Wherein beta is _ij And transmitting the correlation coefficients of the signals for the ith transmitting antenna and the jth transmitting antenna.

It can be demonstrated that [5, appdix 4a ], the maximum likelihood estimate of the parameter θ of equation (4) can be derived from the NM x 1 vector:

generally for simplicity of receiver algorithm complexity, it is desirable that η be a statistically independent sufficient statistic [5 ]]. Performing eigenvalue decomposition on the correlation matrix of the transmitted signal, wherein R is _s ＝UΛU ^H Accordingly, the actual transmitted signal can be regarded as a set of orthogonal signalsIs a linear transformation of (a), namely:

substituting equation (4) and due toThe method comprises the following steps:

accordingly, equation (10) becomes

Wherein the equivalent virtual steering vector with dimension NM×1 is expressed as:

d(θ _l )＝vec(A(θ _l )UΛ ^1/2 ) (14)

for phased array radar, the transmit antenna signals are coherent, where R _s ＝uu ^H Contains only 1 non-zero eigenvalue, soAt this time, the liquid crystal display device,

the effective array element number of the virtual array is only N. For MIMO radar with completely orthogonal transmitting signals of each transmitting antenna, R is _s ＝I _M×M U lambda ^1/2 ＝I _M×M At this time

From the above, orthogonality (correlation) between the signals transmitted by each transmitting antenna affects the number of effective array elements of the virtual array of the MIMO radar, and thus affects the flexibility of signal processing at the receiver side. For this purpose, the perception processing method of the present application is proposed.

The following describes in detail the perception processing method provided by the embodiment of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a sensing processing method, as shown in fig. 2, including:

step 201, in the case that the target information changes, the first device determines first configuration information based on the target information;

step 202, the first device sends first configuration information;

Alternatively, the above-described target information may be understood as information for determining whether or not to perform the updating of the antenna selection information and the signal configuration information. In some embodiments, the target information may include at least one of:

executing a perception result obtained by a first service associated with the first signal in a preset time period;

the target sensing device executes antenna selection information of the first service in the preset time period;

Antenna array information of the target sensing device;

sensing first state information of a target;

channel information;

resource information associated with the first service;

first information for determining a perceiving device.

It should be noted that, when the preset condition is satisfied, the target information will be changed, where the preset condition may include at least one of the following:

the dynamic parameters of the perception target are changed, and the dynamic parameters comprise at least one of speed, angle and distance;

the quantity or the density of the sensing targets in the sensing area is changed;

the environmental clutter in the sensing area changes;

the environmental interference of the sensing area changes;

the available service time-frequency resources change;

the available antenna resources change;

the first signal changes.

The change of the target number, the density and the environmental interference can be understood that the change of the corresponding parameter value is larger than a preset threshold value. The change of the parameters can influence the perceived performance, and the antenna selection information is adaptively adjusted, so that the perceived performance can be maintained or improved. The change of the available antenna resources may be understood as that the antenna resources that are integrally available to all sensing devices that perform the first service change, for example, the change of the antenna resources that are available to a certain sensing device may cause the change of the antenna resources that are integrally available, or may also cause the change of the antenna resources that are integrally available to increase or decrease or update the sensing device. The above-mentioned change of the first signal may be understood as a change of the orthogonal manner, the sequence of the first signal, or a change of the sequence of the signal of at least one transmitting antenna in the first signal.

In the embodiment of the application, the first device may receive the target information from at least one sensing device associated with the first signal, the first device may also receive part of information in the target information from at least one sensing device, and the first sensing device may calculate and determine another part of information in the target information, and the first device may also directly calculate and determine the target information, which is not limited herein. The sensing device may be called as a sensing node, and the sensing device includes the transmitting device and the receiving device. The transmitting device and the receiving device may be the same device or different devices. The first device may be understood as a network-side device, and specifically may be a device in a core network or a base station. It should be understood that determining the first configuration information based on the target information may be understood as determining the first configuration information based on the target information of the target sensing device, or determining the first configuration information based on a combination of the target sensing device and the target information of other sensing devices of the at least one sensing device. For example, in some embodiments, when the distance between the sensing target and the target sensing device changes such that the antenna resources of the target sensing device need to be increased or decreased, the first configuration information may be determined in conjunction with the target information of all the sensing devices. For example, in some embodiments, the first configuration information may be determined based on the target information of the target sensing device in the event that the channel information of the target sensing device changes.

Alternatively, the first configuration information may include first configuration information of the transmitting device and first configuration information of the receiving device. The target sensing device comprises a transmitting device when antenna selection information of the transmitting device needs to be updated; in case that the antenna selection information of the receiving device needs to be updated, the target sensing device includes the receiving device.

Optionally, in some embodiments, the first signal is a set of signals transmitted by each transmitting antenna in a MIMO-ISAC system with multiple input multiple output communication perception integration, and the signals transmitted by each transmitting antenna in the MIMO-ISAC system are mutually orthogonal or quasi-orthogonal. It should be understood that in the MIMO-ISAC system, each transmitting antenna signal may be a signal that has only a sensing function and does not include transmission information, such as pseudo-random sequences used in existing synchronization and reference signals, including m-sequences, zadoff-Chu sequences, gold sequences, etc., and may also be a single-frequency Continuous Wave (CW), a frequency modulated Continuous Wave (Frequency Modulated CW, FMCW), ultra-wideband gaussian pulse, etc., which are commonly used by radar; the method can also be a newly designed special sensing signal with good correlation characteristics and low peak-to-average power ratio (PAPR), or a newly designed general sense integrated signal which not only carries certain information, but also has better sensing performance.

Alternatively, the first state information may include one or more measurement parameter values, for example, may include measurement parameter values such as a position coordinate of the sensing target, a distance between the sensing target and the transmitting device, and a moving speed of the sensing target, and the first state information may be determined based on a priori information of the sensing target before the sensing target is sensed, and may be updated based on the measurement parameter values obtained by the sensing after the sensing is performed. The above-described sensing result may be determined based on measurement parameter values obtained by one or more sensing measurements. This is illustrated by the following:

in some embodiments, the sensing result may be a sensing parameter value obtained by one sensing measurement, for example, in a sensing scene where a sensing target is location-sensed, the sensing result may be location coordinates of the sensing target.

In some embodiments, the sensing result may be a target result determined based on a sensing parameter value obtained by a sensing measurement, for example, in a sensing scene in which a sensing target is contour-sensed, the sensing result may be computationally determined based on a plurality of sensing parameter values such as a position coordinate of the sensing target, a departure azimuth angle and a departure pitch angle of the sensing target.

In some embodiments, the sensing result may be determined based on sensing parameter values obtained by a plurality of sensing measurements, for example, in a sensing scene in which a sensing target is subjected to track sensing, the sensing result may be a track determined by position coordinates of the sensing target obtained by performing the sensing measurements a plurality of times.

The first service may be understood as a sensing service or a sense of general integration service. The above-mentioned preset period of time may be understood as a period of time before the first device determines the first configuration information, i.e. a period of time before the antenna selection information and the signal configuration information are updated. That is, the antenna selection information and the signal configuration information may be updated based on the sensing result of performing the sensing service for a preset period of time before the antenna selection information and the signal configuration information are updated. In this way, the first configuration information is determined according to the target information, so that the antenna selection information and the signal configuration information of the target sensing equipment can be updated according to the current sensing environment, and further the sensing performance can be effectively improved.

Optionally, the signal configuration information includes at least one of:

a resource cycle class parameter for controlling at least one of a time domain repetition period, a time domain repetition number, a frequency domain repetition period, and a frequency domain repetition number of the first signal resource;

A resource location class parameter, the resource location class parameter being used to control a time-frequency location of the first signal resource;

a resource pattern class parameter for controlling a basic time-frequency pattern of the first signal resource;

a resource modulation class parameter, the resource modulation class parameter being used to control the phase modulation of the first signal;

a resource coding class parameter for controlling orthogonal code resource allocation of the first signal based on code division multiplexing CDM;

a signal sequence type;

signal sequence length;

an initial seed for producing the first signal.

Optionally, the resource cycle class parameter is at least one of: resource set period, resource repetition coefficient, resource time interval and subcarrier spacing.

The resource location class parameter includes at least one of: resource start frequency, resource set slot offset, resource unit offset, resource slot offset, and resource symbol offset.

Optionally, the resource pattern class parameter includes at least one of: number of symbols in resource time slot, resource comb size and silent pattern.

Optionally, the orthogonal type of the transmission signal of each transmission antenna includes at least one of the following: time division multiplexing (Time division multiplexing, TDM), frequency division multiplexing (Frequency Division Multiplex, FDM), doppler frequency division multiplexing (Doppler Division Multiplexing, DDM), and code division multiplexing (Code Division Multiplexing, CDM).

In the embodiment of the present application, when the orthogonal type of the transmission signal of each transmission antenna includes TDM, it may be understood that the transmission signal of the transmission antenna includes a TDM signal; when the orthogonal type of the transmission signal of each transmission antenna includes FDM, it may be understood that the transmission signal of the transmission antenna includes FDM signal; when the orthogonal type of the transmission signal of each transmission antenna includes DDM, it can be understood that the transmission signal of the transmission antenna includes DDM signal; when the orthogonal type of the transmission signal of each transmission antenna includes CDM, it can be understood that the transmission signal of the transmission antenna includes CDM signal. Further, in the case where the orthogonal type of the transmission signal of each transmission antenna includes two orthogonal types, the transmission signal of the transmission antenna may be understood as a combination of two signals, for example, when the orthogonal type of the transmission signal of each transmission antenna includes TDM and FDM, the transmission signal of the transmission antenna may be understood as a combination of TDM signal and FDM signal.

Optionally, the transmitting signals of the transmitting antennas in the MIMO-ISAC system are orthogonal or quasi-orthogonal to each other, including at least one of:

transmitting signals of at least two transmitting antennas in the MIMO-ISAC system respectively use mutually orthogonal time domain resources;

Logically, 1 Antenna array element or 1 Antenna sub-array corresponds to 1 Antenna Port (Antenna Port) or resource ID (Resource Identity), and thus the selected object can also be regarded as an Antenna Port or resource ID.

For a better understanding of the application, the following description of antenna selection and signal configuration joint adaptation is provided by some embodiments.

Optionally, in some embodiments, in the track-following perception scenario of the perceived target, the distance or direction changes, requiring a change in antenna spacing or a change in antenna spacing and number, and a change in signal configuration information, to maintain or increase the angular resolution. The perceived target may be a moving target of a motor vehicle, a bicycle, an unmanned aerial vehicle, a pedestrian, etc. The sensing mode may be a mode that the node a sends the first signal, and the node B receives the first signal, or the node a spontaneously receives the first signal.

As shown in fig. 3, taking unmanned plane track tracking as an example, it is assumed that node a is a terminal, and node B is a base station, and track tracking sensing is performed on the unmanned plane in a certain sensing area. The unmanned aerial vehicle is flown upwards from far to near relative to the base station and changing direction at position 3. In the position 1, since the unmanned aerial vehicle is far away from the base station, a higher angular resolution is required for positioning the unmanned aerial vehicle, the antenna array elements { A1, A2} of the terminal send a first signal, and the antenna array elements { B1, B2, B3, B4, B5} of the base station are received, so that the constructed virtual array can have a larger aperture in the horizontal direction. At this time, the first signal (TDM+FDM signal) in the stage 1 can be used to ensure that the MIMO-ISAC system has a certain distance resolution, a lower distance and Doppler sidelobes, and the Doppler non-ambiguity range is properly reduced; when the unmanned aerial vehicle arrives at the position 2, the unmanned aerial vehicle is close to the base station, at the moment, the antenna array elements { A1, A2} of the terminal send a first signal, and the base station antenna array elements { B1, B2, B3} can meet the angle resolution requirement after receiving, so that a part of antenna resources are saved. Since the target distance is relatively short and the total number of transmitting and receiving antennas is relatively small, the first signal (TDM signal) of the stage 2 can be used at the moment, so that the total transmitting power and the Doppler no-ambiguity range can be properly reduced; when the unmanned aerial vehicle is at the position 3 and the position 4, the first device adjusts the antennas used for sensing by the terminal and the base station based on the first state information and/or the sensing result (such as the statistical mean/variance/standard deviation of the difference between the historical measured value and the predicted value of at least 1 item of sensing target distance, speed and angle) fed back by the computing node. For example, the terminal antenna elements { A1, A2, A3, A4} send the first signal, and the base station antenna elements { B1, B2, B3, B6, B7} receive, so that the constructed virtual array can have a larger aperture in the vertical direction, and the unmanned aerial vehicle track tracking position sensing precision is ensured. The first signal of stage 3 (TDM + FDM signal) may be used at this point to properly reduce the range resolution, but to ensure lower range and doppler sidelobes, as well as higher doppler resolution.

The time-frequency pattern of the first signal in the stage 1 is shown in fig. 4A, the time-frequency pattern of the first signal in the stage 2 is shown in fig. 4B, and the time-frequency pattern of the first signal in the stage 3 is shown in fig. 4C.

The first signal adaptation of the above 3 stages may be implemented by changing a Resource cycle class parameter (including a Resource set period, a Resource repetition coefficient, a Resource time slot, a subcarrier interval, etc.), a Resource location class parameter (including a Resource start frequency, a Resource set slot offset, a Resource Element (RE) offset, a Resource Block (RB) offset, a Resource slot offset, a Resource symbol offset, etc.) in the signal configuration information; the MIMO-ISAC antenna selection adaptation may be achieved by changing the antenna selection information (including the antenna element ID used to transmit and/or receive the first signal, the location information of the antenna element relative to a certain local reference point on the antenna array, the antenna selection bitmap information, etc.).

Optionally, in some embodiments, the number of perceived targets is changed in the perceived area, requiring a change in the number of antennas or a change in the antenna density, and a change in the signal configuration information, to change the maximum number of simultaneously perceivable perceived targets, as well as the range or doppler perception accuracy.

The method of the application can also be used for ensuring or improving the perception performance of the preset dynamic environment. For example, traffic sensing for an intersection (which may include sensing the number of vehicles passing over a period of time, the speed and location of each vehicle (the lane in which it is located), etc.).

As shown in fig. 5, the roadside base station senses traffic on a certain section of road by self-receiving means. The MIMO-ISAC system may enable differentiation of vehicles and speed and position determination of individual vehicles by measuring the first signal echo delay, angle and doppler frequency. The maximum simultaneous perceivable perceived target number of the MIMO-ISAC is determined by the number of antennas of the transmitting array and the receiving array [3,5], namely:

wherein L is _max The maximum simultaneous perception target number is represented, M is the number of transmitting antennas, and N is the number of receiving antennas.

In a period of traffic non-congestion, vehicles on a road are sparse, at the moment, a base station (or first equipment indication base station) selects antenna array elements { A1, A2} to send a first signal, and the antenna array elements { B2, B3, B5, B6} are received, so that the requirement of perception performance can be met (the requirement of perception in first information and/or the QoS of perception/communication integration are met). At this point, the first signal of stage 1 (FDM signal) shown in fig. 5A can be used, with appropriate sacrifice of range resolution, but with guaranteed low range and doppler sidelobes for the system, and moderate maximum simultaneous perceivable target number L, under limited bandwidth resources _max ；

If the traffic congestion period is entered, the first device adjusts the first signal receiving antenna array elements of the base station to { B1, B2, B3, B4, B5, B6, B7, B8, B9}, based on the first status information and/or the sensing result (e.g. the number/density of sensing targets in the sensing area) fed back by the computing node, thereby increasing the maximum simultaneously perceivable sensing target number L of the MIMO-ISAC system _max . Meanwhile, the first signal (DDM signal) of the stage 2 shown in fig. 5B can be used to properly reduce the Doppler non-ambiguity range, but ensure that the system has very low distance and Doppler side lobe, and has optimal clutter suppression performance, thereby being suitable for sensing multiple moving targets and ensuring comprehensive sensing performance.

Optionally, in some embodiments, the available time/frequency/doppler frequency/orthogonal code resources of the sensing node are changed, requiring adaptation through signal and antenna selection, maintaining sensing performance.

In the MIMO-ISAC system, a certain constraint relation exists between antenna resources and time-frequency resources as well as orthogonal code resources. Still taking fig. 5 traffic perception as an example, assuming that the first signal (FDM signal) of phase 1 shown in fig. 5A is initially employed, for some reason (e.g., other high priority traffic resource preemption) the available frequency resources are reduced by 50%, one solution is to switch to the perception of TDM signals in combination with dynamic antenna selection in order to maintain a predetermined perceived performance.

In a traffic non-congestion period, respectively selecting A1 and A2 to transmit a first signal and receiving antenna array elements { B2, B3, B5 and B6} at different 2 moments within a preset time; in the traffic congestion period, the first signal receiving antenna array element is { B1, B2, B3, B4, B5, B6, B7, B8, B9}. Alternatively, the number of transmitting antenna array elements can be increased appropriately, and the tdm+ddm signal is adopted to realize the maintenance of the perceptual performance.

It should be noted that, in the above-mentioned scenario, it is required to ensure that the sensing target state or the sensing area environment does not change significantly within the preset time of antenna selection. In addition, in the above embodiment, only several optional first signal configurations and antenna selection schemes are given, and the configuration can be flexibly and adaptively configured according to practical situations when the method is applied. Where the signal configuration gives only a signal time-frequency pattern of 1 RB and 1 slot as an example, the first signal may occupy multiple RBs and slot resources in practical applications.
