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. Although radar and communication systems 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 the 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.

In a mobile communication network, a base station (including 1 or more TRP, user Equipment (UE) on the base station (including 1 or more subarrays/panels) on the UE) can be used as a sensing node participating in ISAC service.

Depending on whether the sensing node is the same device, two sensing modes can be divided: a sends out B and receives, A spontaneously self-receives. The A-sending B-receiving means that the sensing node A and the sensing node B are not the same equipment and are separated in physical position; a self-receiving means that the sensing signal transmission and the sensing are performed by the same device, and the sensing node A senses by receiving a signal echo sent by itself. The following unifies the above A, B and receive perceptions as the first perceptions, and the corresponding perceptions are the second perceptions; a self-receiving perception is a second perception, and the corresponding perception mode is a first perception mode.

The following describes in detail the sensing mode switching processing method provided by the embodiment of the 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 method for processing switching between sensing modes, as shown in fig. 2, where the method for processing switching between sensing modes includes:

step 201, under the condition that it is determined that a sensing mode of a sensing target is switched from a first sensing mode to a second sensing mode, a first device sends a first request message to at least one first candidate node, where the first request message is used to request the first candidate node to execute a sensing operation of the sensing target in the second sensing mode;

Step 202, the first device receives a first response message from the first candidate node;

In the embodiment of the present application, the switching of the first sensing mode to the second sensing mode to determine whether to initiate the sensing mode of the sensing target may be performed by the first device or may be performed by another device, which is not limited herein. Before the fact that the sensing mode of the sensing target is switched from the first sensing mode to the second sensing mode is determined, the sensing mode of the sensing target is the first sensing mode, and the first sensing node for executing sensing operation on the sensing target according to the first sensing mode is a terminal or network side equipment.

Alternatively, the first candidate node may be understood as a node that may perform a sensing operation on the sensing target in the second sensing manner, and may include at least one of a candidate terminal and a candidate network side device. Further the first candidate node may or may not comprise a first aware node.

Wherein the candidate terminal may be determined based on at least one of:

position information of the terminal;

terminal antenna panel orientation information;

the state information of the terminal may include, for example, information of a moving speed, a moving direction, a period of time for keeping stationary/moving, and the like;

the sensing capability information of the terminal may include, for example, sensing coverage of the terminal, maximum bandwidth available for sensing, maximum sustainable time of sensing service, type of sensing signal and frame format which can be supported, and terminal antenna array information (such as array type, number of antennas, array aperture, antenna polarization characteristic, array element gain and directivity characteristic, etc.);

the current available Resource information of the terminal for sensing may include, for example, time resources (symbol number, slot number, frame number, etc.), frequency resources (such as Resource Block (RB) number, resource Element (RE) number, total bandwidth, available frequency band position, etc.), antenna resources (such as antenna array number/antenna sub-array number), phase modulation resources (such as hardware phase shifter number), orthogonal code resources (such as orthogonal code length and number), etc.;

The channel state information of the terminal may include at least one of channel transfer function/channel impulse response, channel quality indication (Channel Quality Indicator, CQI), precoding matrix indication (Precoding Matrix Indicator, PMI), CSI-RS resource indication, SSB resource indication, layer Indicator (LI), rank Indicator (RI), and Layer 1 reference signal received power (L1-Reference Signal Received Power, L1-RSRP) of at least one communication link, for example.

The candidate network-side device may be determined based on at least one of:

the sensing requirements can include, for example, a sensing target area, an object type, a required sensing function, a sensing purpose, a sensing result, and the like;

perceived quality of service (Quality of Service, qoS), for example, may include at least one of: the sensing resolution (further, may be divided into ranging resolution, angular resolution, speed measurement resolution, imaging resolution, etc.), sensing accuracy (further, may be divided into ranging accuracy, angular accuracy, speed measurement accuracy, positioning accuracy, etc.), sensing range (further, may be divided into ranging range, speed measurement range, angular range, imaging range, etc.), sensing time delay (e.g., time interval from sensing signal transmission to obtaining sensing result, or time interval from sensing requirement initiation to obtaining sensing result), sensing update rate (e.g., time interval between performing sensing twice and obtaining sensing result), detection probability (e.g., probability of being correctly detected in case of sensing object existence), false alarm probability (e.g., probability of erroneously detecting sensing object in case of sensing object absence), sensing security, and sensing privacy;

Sensing the measurement quantity;

the sensing measurements may include, for example, sensing results obtained directly or indirectly based on at least one sensing measurement;

the sensing condition may include, for example, at least one of a sensing start time, a sensing end time, a sensing duration, and the like;

the prior information of the sensing target or the sensing region can comprise at least one of the type of the sensing target, the approximate position/region of the sensing target, the historical state (speed, angle, distance, acceleration and space orientation) of the sensing target and the like;

the perceptual handover success decision condition (e.g., may indicate that the measurement of the at least one perceptual measurement and/or the measurement of the communication measurement reaches a preset threshold within a preset time/a preset number of times).

It should be understood that the switching of the sensing modes in the mobile communication network is divided into two cases of switching the first sensing mode to the second sensing mode and switching the second sensing mode to the first sensing mode. Fig. 2a shows a case where the first sensing mode is switched to the second sensing mode, and fig. 2b shows a case where the second sensing mode is switched to the first sensing mode. Wherein, considering that the sensing node in the network may change before and after the handover, and the sensing node may be a network side device or UE after the handover, each of the two cases has 6 combinations. Taking the example of switching the first sensing mode to the second sensing mode, the method specifically includes: based on the difference between the first sensing node and the first sensing node, the corresponding switching scenario may include the following scenarios:

Switching scenario 1: the network side equipment executes the sensing operation according to the first sensing mode and switches to the network side equipment and the terminal execute the sensing operation according to the second sensing mode;

switching scenario 2: the network side device executes the sensing operation according to the first sensing mode and switches to the terminal and the terminal executes the sensing operation according to the second sensing mode;

switching scenario 3: the terminal executes the sensing operation according to the first sensing mode and switches to the network side equipment and the terminal executes the sensing operation according to the second sensing mode;

switching scenario 4: the terminal executes the sensing operation according to the first sensing mode and switches to the terminal and executes the sensing operation according to the second sensing mode;

switching scenario 5: the method comprises the steps of carrying out a first treatment on the surface of the The terminal executes the sensing operation according to the first sensing mode and switches to the terminal and executes the sensing operation according to the second sensing mode;

switching scenario 6: the network side device executes the sensing operation according to the first sensing mode and switches to the network side device and the network side device executes the sensing operation according to the second sensing mode.

Fig. 2c presents a schematic view of a different combination of switching the first perception mode to the second perception mode. The network side equipment is a base station, and in order to indicate that the sensing node may be different equipment, a base station A, a base station B and a base station C are used for distinguishing UE A, UE B and UE C.

Optionally, the first response message is used to indicate whether the first candidate node agrees to participate in the perception of the perception target in the second perception manner. The first device may determine, based on the received first response message, a first candidate node that agrees to participate in sensing, thereby further determining a target candidate node that performs a sensing operation on the sensing target according to a second sensing mode after the sensing mode of the sensing target is switched.

Further, in some embodiments, the first response message may be used to indicate whether the first candidate node and the corresponding second candidate node agree to participate in the perception of the perception target in the second perception manner. For example, in the case that the first candidate node is a network side device, the first candidate node may feed back whether the first candidate node and a second candidate node (i.e., a terminal) that performs a sensing operation in a second sensing manner together with the first candidate node agree with the second sensing manner to participate in sensing of the sensing target.

It should be noted that, in the embodiment of the present application, the sensing measurement may include at least one of the following:

the first-stage measurement quantity can comprise a complex result of received signal/channel response, amplitude/phase, I/Q circuit and operation results thereof (operation comprises addition, subtraction, multiplication, matrix addition, multiplication, matrix transposition, trigonometric relation operation, square root operation, power operation and the like, and threshold detection results, maximum/minimum value extraction results and the like of the operation results, and operation also comprises fast Fourier transform (Fast Fourier Transform, FFT)/inverse fast Fourier transform (Inverse Fast Fourier Transform, IFFT), discrete Fourier transform (Discrete Fourier Transform, DFT)/inverse discrete Fourier transform (Inverse Discrete Fourier Transform, IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform, digital filtering and the like, and threshold detection results, maximum/minimum value extraction results and the like of the operation results);

Fourth-level measurement quantity (advanced property/state), the fourth-level measurement quantity including: sensing at least one of the presence, trajectory, motion, expression, vital sign, quantity, imaging result, weather, air quality, shape, material, and composition of the target.

Optionally, the perceived measurement further includes corresponding tag information, which may include, for example, at least one of: sensing signal identification information, sensing measurement configuration identification information, sensing traffic information (e.g., sensing traffic ID), data subscription ID, measurement volume usage (e.g., communication, sensing, sense), time information, sensing node information (e.g., terminal ID, node location, device orientation), sensing link information (e.g., sensing link sequence number, transceiving node identification), measurement volume specification information (form, e.g., magnitude value, phase value, complex value of magnitude and phase combination; resource type, e.g., time domain measurement, frequency domain resource measurement), measurement volume index information (e.g., signal to noise ratio (Signal Noise Ratio, SNR), sensing SNR).

Optionally, in some embodiments, the first response message includes at least one of first indication information and a first perception measurement;

The first indication information is used for indicating whether the first candidate node agrees to execute the sensing operation on the sensing target according to the second sensing mode or whether the first candidate node and a second candidate node associated with the first candidate node agree to execute the sensing operation on the sensing target according to the second sensing mode; the first sensing measurement result is obtained after the first candidate node executes sensing operation on the sensing target according to the second sensing mode.

In an embodiment of the present application, the sensing measurement result may include a measurement value of the sensing measurement amount and/or a sensing result determined based on the measurement value of the sensing measurement amount (may be a final sensing result or an intermediate sensing result used for calculating the final sensing result).

And the second device can determine whether to take the first device and the first candidate node associated with the first device as target candidate nodes or not based on the third sensing measurement result by feeding back the third sensing measurement result through the second response message, so that the second device can determine the sensing performance of the sensing operation of the first device and the first candidate node on the sensing target according to the second sensing mode. Thus, the perceptibility of the target candidate node to the perception target after the switching can be improved.

In order to better understand the present application, the following description is made based on different handover scenarios.

Switching scenario 1: the network side device performs the sensing operation switching according to the first sensing mode, and the network side device and the terminal perform the sensing operation according to the second sensing mode (i.e. the source base station first sensing switching is the base station-UE second sensing), which specifically comprises the following procedures.

Step 11, the network side device performs handover measurement.

The core network equipment (for example, a sensing function network element) sends a switching measurement request to the source base station (network side equipment for executing sensing operation in a first sensing mode), and the source base station receives the switching measurement request, performs switching measurement and feeds back a switching measurement report to the core network equipment;

or the source base station actively performs handover measurement to acquire a handover measurement report. Optionally, the source base station sends a handover measurement report to the core network device.

Alternatively, the core network device may send handover measurement configuration information necessary for handover measurement to the source base station before the source base station makes the handover measurement. Alternatively, the handover measurement configuration information is included in a handover measurement request. The handover measurement configuration information may be described in detail herein with reference to the above embodiments.

Alternatively, step 11 may be triggered based on a target event. The content of the target event may be omitted herein with reference to the above embodiments.

Step 12, the source base station decides whether to initiate a handover or not based on the handover measurement report, or the core network device decides whether to initiate a handover request according to the handover measurement report acquired from the source base station.

If a handoff is not initiated, the subsequent processing may be to maintain or end the current first sense (i.e., the sense operations performed in the first sense manner).

If a handover is initiated, the core network device or the source base station decides which node is to be switched to the second sensing mode, which is specifically one of the following cases:

case 1: the source base station decides to switch to the base station-UE second perception.

The source base station sends request information A to at least one candidate target base station, the request information A is a request information A receiving party, and the second perception of the base station-UE is carried out after the perception mode switching is completed.

And the candidate target base station sends request information B to at least one candidate target UE, wherein the request information B is a request information B receiving party, and the base station-UE second perception is carried out after the perception mode switching is completed.

Optionally, the source base station sends indication information a to the core network device, the indication information a informs the receiving side of the indication information a, and the second perception of the base station-UE is performed after the perception mode is switched.

Case 2: the core network device decides to switch to the base station-UE second perception.

The core network device sends request information a to at least one candidate target base station.

The candidate target base station transmits request information B to at least one candidate target UE.

Optionally, the core network device sends the indication information a to the source base station.

Optionally, the candidate target base station comprises a source base station.

Case 3: the source base station decides to actively switch to the base station-UE second perception. In this case, the source base station is a candidate target base station.

The source base station transmits request information B to at least one candidate target UE.

Optionally, the source base station sends indication information B to the core network device, where the indication information B indicates an indication information B receiver, and after the sensing mode switching is completed, the indication information B sender performs a second sensing.

Optionally, case 3 further includes case 1, where at least one candidate target base station in case 1 is another candidate target base station other than the source base station.

Optionally, the source base station or the core network device includes suggested third parameter configuration information in the request information a and/or the request information B. And the third parameter configuration information is used for executing second perceived perception parameter configuration of any one of the candidate target base station, the candidate target UE, the target base station and the target UE.

If the request information a and the request information B include a soft handover request, optionally, the third parameter configuration information includes parameter configuration information corresponding to soft handover.

And step 13, the candidate target base station and the candidate target UE decide whether to accept the second perception after switching the perception mode. The following 2 cases are classified:

case one: the candidate target base station and the candidate target UE agree to the handover. The following procedure is performed in sequence:

13-1) the candidate target base station and the candidate target UE perform the sensing parameter configuration based on at least one of the request information a, the request information B and the third parameter configuration information, and perform the second sensing.

13-2) after performing at least one sensing measurement, the candidate target base station transmits first response information to the source base station or the core network device, where the first response information indicates a first request information sender, and after the sensing mode is switched, the first response information sender agrees to execute second sensing.

The first response information content includes at least one of:

performing a measurement and/or a perception result of the at least one perception measurement of the first perception;

and (5) measuring a preset measurement result of at least one perception performance evaluation index.

Optionally, the first response information content may further include at least one of:

And first parameter configuration information for performing second perceived parameter configuration by the target perceived node (target base station and/or target UE).

After the handover, the second perceived sensing node (base station/UE) information (including ID of the perceived node, location information, antenna panel orientation information, status information, perceived capability information, currently available resource information for perception, etc.) is participated in with the candidate target base station;

and measuring the result of the communication measurement.
