[0043] In some embodiments, the network side devices and terminals may have perception capabilities in addition to communication capabilities. Perception capabilities refer to one or more devices with perception capabilities that can sense the direction, distance, speed and other information of target objects through the transmission and reception of wireless signals, or detect, track, identify, image and the like the target objects, events or environments. Some perception functions and application scenarios are shown in Table 1:

[0044] Table 1

[0045]

[0046] It should be noted that the perception category shown in Table 1 above is only an example, and the category of perception measurement is not limited in the embodiments of the present application.

[0047] In addition, the embodiments of the present application can be applied to the communication and perception integration scenario, where communication and perception integration refers to the integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system. While transmitting information, the system can perceive information such as direction, distance, speed, and detect, track, and identify target devices or events. The communication system and the perception system complement each other to achieve overall performance improvement and bring a better service experience.

[0048] For example: the integration of communication and radar is a typical communication-perception integration (communication-perception fusion) application, and the integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, improved spectrum efficiency, reduced mutual interference, etc., thereby improving the overall performance of the system.

[0049] In the embodiment of the present application, according to the difference between the sensing signal sending node and the receiving node, it may include but is not limited to Figure 2 The six sensing links shown in FIG. Figure 2 Each perception link is illustrated by a sending node and a receiving node. In the actual system, different perception links can be selected according to different perception requirements. Each perception link can have one or more sending nodes and receiving nodes, and the actual perception system can include multiple different perception links. Figure 2 The perception targets in the example are people and cars, and it is assumed that people and cars do not carry or install signal receiving / transmitting equipment. The perception targets in actual scenes will be richer.

[0050] Sensing link 1: The base station sends and receives sensing signals on its own. In this mode, the base station sends sensing signals and obtains sensing results by receiving the echo of the sensing signals.

[0051] Sensing link 2: air interface sensing between base stations. In this mode, base station 2 receives the sensing signal sent by base station 1 and obtains the sensing result.

[0052] Perception link 3: Uplink air interface perception. In this mode, the base station receives the perception signal sent by the terminal and obtains the perception result.

[0053] Perception link 4: Downlink air interface perception. In this mode, the terminal receives the perception signal sent by the base station and obtains the perception result.

[0054] Perception link 5: Terminal self-transmitting and self-receiving perception. In this mode, the terminal sends a perception signal and obtains the perception result by receiving the echo of the perception signal.

[0055] Perception link 6: Sidelink perception between terminals. For example, terminal 2 receives a perception signal sent by terminal 1 to obtain a perception result, or terminal 1 receives a perception signal sent by terminal 2 to obtain a perception result.

[0056] In some embodiments, the above six types of perception links are used as examples for explanation. Different perception links have their own advantages and disadvantages, as shown in Table 1 below. Depending on whether the perception devices are the same device, they can be further divided into two types of perception links: device A sends and device B receives, and device A sends and receives by itself. Device A sends and device B receives means that perception device A and perception device B are not the same device, and are physically separated, that is, perception links 2, 3, 4, and 6; device A sends and receives by itself means that the perception signal is sent and received by the same device, and perception device A perceives by receiving the signal echo sent by itself, that is, perception link 1 and perception link 5. Taking into account the advantages and disadvantages of different perception links, in actual applications, the perception performance can be improved based on the joint perception of multiple links.

[0057] Table 1:

[0058]

[0059] In some embodiments, due to the mobility of the perception target or perception device, or changes in other environmental conditions, it is necessary to switch the perception link. The embodiment of the present application combines multi-link joint perception with switching. In order to ensure the continuity of the perception service for mobile targets and improve the perception switching performance, in the process of switching from the spontaneous self-transmitting and self-receiving perception of perception device A to the spontaneous self-transmitting and self-receiving perception of perception device B, the perception link of device A sending and device B receiving is used for joint perception at the same time, and the perception results sent by device A and received by device B and the spontaneous self-transmitting and self-receiving perception results are used together as switching conditions, which can ensure the perception performance during the switching process. And it can reduce the perception context interaction overhead (device B, as the target device to be switched, and also as the perception receiving device of the A sending and B receiving link, can obtain perception information by itself).

[0060] In some embodiments, the three sensing links involved are as follows: Figure 3 As shown, they are perception link 301, perception link 302 and perception link 303, wherein perception link 301 represents device A sending and device A receiving, perception link 302 represents device A sending and device B receiving, and perception link 303 represents device B sending and device B receiving.

[0061] exist Figure 3In the perception link shown, the perception device A and the perception device B can both be network-side devices, or both be terminals, or one of them can be a network-side device and the other can be a terminal. Among them, the signaling transmission between the network-side device and the terminal, and between the terminal A and the terminal B can be through the Radio Resource Control (RRC) signaling or the Media Access Control Element MAC CE or layer 1 signaling or other newly defined perception signaling; the signaling transmission between the perception network function and the terminal can be through NAS signaling (forwarded via AMF) or through RRC signaling or the Media Access Control Element (MAC CE) or layer 1 signaling or other newly defined perception signaling; the interaction between the perception network function and the network-side device can be forwarded to the wireless access network through the N2 interface by using the AMF; or the core network perception network function sends it to the UPF, and the UPF sends it to the wireless access network through the N3 interface; or it is sent to the wireless access network device through a newly defined interface; the signaling transmission between wireless access network devices can be through the Xn interface.

[0062] In the embodiment of the present application, the sensing network function may also be called a sensing network element or a sensing management function (Sensing Management Function, Sensing MF), which may be located on the RAN side or the core network side, and refers to a network node in the core network or RAN responsible for at least one function of sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It may be based on the AMF or LMF upgrade in the mobile communication network, or it may be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing network function / sensing network element may include at least one of the following:

[0063] Target information is interacted with a wireless signal sending device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area), wherein the target information includes a perception processing request, a perception capability, perception auxiliary data, a perception measurement quantity type, a perception resource configuration information, etc., so as to obtain the value of the target perception result or the perception measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal may also be referred to as a perception signal.

[0064] The perception method to be used is determined based on factors such as the type of perception service, perception service consumer information, required perception service quality (QoS) requirement information, the perception capability of the wireless signal sending device, the perception capability of the wireless signal measuring device, and the like. The perception method may include: wireless access network device A sends and wireless access network device B receives, or the wireless access network device sends and the terminal receives, or the wireless access network device A sends and receives by itself, or the terminal sends and the wireless access network device receives, or the terminal sends and the wireless access network device receives by itself, or terminal A sends and terminal B receives, etc.

[0065] The perception device serving the perception service is determined based on factors such as the type of perception service, information about the perception service consumer, required perception QoS requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device, wherein the perception device includes a wireless signal sending device or a wireless signal measuring device.

[0066] Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources of wireless access network equipment or terminals accordingly;

[0067] The values ​​of the perceived measurement quantities are processed or calculated to obtain the perceived results. In addition, the perceived results can be verified and the perceived accuracy can be estimated.

[0068] In the following, in conjunction with the accompanying drawings, a measurement switching method, apparatus and device provided by an embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0069] See also Figure 4 , Figure 4 is a flow chart of a measurement switching method provided in an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0070] Step 401: The first device obtains a measurement report fed back by the second device.

[0071] Among them, the above-mentioned first device can be a terminal or a network side device, such as a wireless access network device or a core network element.

[0072] The second device mentioned above may be a terminal or a wireless access network device.

[0073] The measurement report fed back by the second device obtained by the first device may be a measurement report returned by the first device after the second device performs switching measurement, such as the second device performs switching measurement on the signal sent by the first device or the signal sent by the second device to obtain the measurement report, and feeds it back to the first device.

[0074] Step 402: When determining to switch the perception measurement based on the measurement report, the first device sends a switching command to the second device, where the switching command is used to switch the perception measurement of the perception target from the source node to the second device.

[0075] The above-mentioned determination of the perception measurement switching based on the measurement report may be that the first device decides on the perception measurement switching based on the above-mentioned measurement report, such as the above-mentioned measurement report indicates that the second device performs perception measurement better than the above-mentioned source node performs perception measurement, or the above-mentioned measurement report indicates that the measurement result of the second device meets a preset condition, such as the signal quality is higher than a preset threshold, or the above-mentioned measurement report indicates that the distance between the second device and the perception target is within a preset range, etc.

[0076] The above-mentioned source node is a device that performs perception measurement on the above-mentioned perception target before sending the above-mentioned switching command or when sending the switching command, such as a terminal or a wireless access network device that performs perception measurement on the above-mentioned perception target before sending the above-mentioned switching command or when sending the switching command.

[0077] In some implementations, the first device may be the source node, or the first device may not be the source node, such as the first device is a core network element or a perception network function.

[0078] After the second device receives the switching command, the second device performs perception measurement on the perception target.

[0079] In the embodiment of the present application, the source node may also be referred to as a source device, and the second device may also be referred to as a target node or a target device.

[0080] In an embodiment of the present application, by sending a switching command to the second device, it is supported to switch the perception measurement of the perception target from the source node to the second device, so as to improve the perception measurement performance. In addition, since the switching command is sent to the second device when the perception measurement switching is determined based on the measurement report fed back by the second device, the perception measurement switching is made more reliable, such as being able to implement the perception measurement switching only when the second device supports the perception switching or the measurement report of the second device meets the corresponding conditions, thereby making the perception measurement switching more reliable.

[0081] As an optional implementation manner, the measurement report is a measurement report obtained by performing a switching measurement based on at least one of the first signal and the second signal;

[0082] The first signal is a signal sent by the source node, and the second signal is a signal sent by the second device.

[0083] The above-mentioned switching measurement may be a perception measurement or a communication measurement.

[0084] The above measurement report is a measurement report obtained by the second device performing a switching measurement on at least one of the first signal and the second signal, and the switching measurement may be a perception measurement or a communication measurement.

[0085] The measurement report may include at least one of the following:

[0086] a measurement report based on the first signal;

[0087] a measurement report based on the second signal;

[0088] A measurement report is generated based on the measurement report based on the first signal and the measurement report based on the second signal.

[0089] In this implementation, since the measurement report is a measurement report obtained by switching measurements based on at least one of the first signal and the second signal, the measurement report can reflect more measurement-related information of the second device, so that the first device can better decide whether to perform perception measurement switching, thereby making the perception measurement switching more reliable.

[0090] Optionally, the measurement report includes at least one of the following:

[0091] The measurement results of the perceived measurement quantity, the performance indicator information of the signal, and the measurement event information;

[0092] The measurement event information includes at least one of the following:

[0093] Event information associated with the measurement results of the perceived measurement quantity;

[0094] Event information associated with the signal's performance indicator.

[0095] In the embodiment of the present application, the perceptual measurement quantities can be divided into the following categories:

[0096] The first-level measurement quantity (also called received signal / original channel information) includes at least one of the following:

[0097] Received signal / channel response complex result, amplitude / phase, I-channel / Q-channel and related operation results (operations include addition, subtraction, multiplication and division, matrix addition, subtraction, multiplication and division, matrix transposition, trigonometric relationship operation, square root operation and power operation, as well as threshold detection results, maximum / minimum value extraction results, etc. of the above operation results; wherein, the operation also includes Fast Fourier Transform (FastFourier Transform, FFT) / Inverse Fast Fourier Transform (Inverse Fast Fourier Transform, IFFT), Discrete Fourier Transform (Discrete Fourier Transform, DFT) / Inverse Discrete Fourier Transform (InverseDiscrete Fourier Transform, IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform and digital filtering, as well as threshold detection results, maximum / minimum value extraction results, etc. of the above operation results;

[0098] The second-level measurement quantity (also called basic measurement quantity) includes at least one of the following: delay, Doppler, angle, intensity, and their multi-dimensional combination representation;

[0099] The third level of measurement (also called basic attributes / states) includes at least one of the following: distance, speed, direction, spatial position, acceleration;

[0100] The fourth level of measurement (also known as advanced attributes / states) includes at least one of the following: target presence, trajectory, movement, expression, vital signs, quantity, imaging results, weather, air quality, shape, material, and composition.

[0101] For example, the measurement results of the above-mentioned perception measurement quantities may be measurement results of received signals, original channel information, distance, delay, Doppler, angle, intensity, direction, spatial position, acceleration, trajectory, motion, whether a target exists, etc.

[0102] In this implementation, since the measurement report includes the measurement result of the perception measurement amount, the first device can better determine whether to perform the perception measurement switching, so as to improve the reliability of the perception measurement switching.

[0103] The performance indicator information of the above signal may be at least one of the following:

[0104] Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indication (RSSI), Signal to Noise Ratio (SNR), Signal to Interference plus Noise Ratio (SINR), Perceived SNR, Perceived SINR.

[0105] In this implementation, since the first measurement result includes performance indicator information, the first device can better determine whether to perform perception measurement switching, so as to improve the reliability of perception measurement switching.

[0106] In some embodiments, the perceived SNR may be a ratio of the perceived target associated signal power to the noise power, and the perceived SINR may be a ratio of the perceived target associated signal power to the sum of the powers of noise and interference.

[0107] Taking radar detection as an example, the method for acquiring the power of the perceived target associated signal may be at least one of the following options:

[0108] Based on the time delay one-dimensional graph obtained by fast time dimension FFT processing of the echo signal, a constant false alarm rate detector (CFAR) is performed. The maximum amplitude sample point of the CFAR over-threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude to calculate the perceived target associated signal power, such as Figure 5 As shown;

[0109] Based on the Doppler one-dimensional image obtained by slow time dimension FFT processing of the echo signal, CFAR is performed, and the maximum amplitude sample point over the CFAR threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude to calculate the perceived target associated signal power. Figure 5 As shown;

[0110] Based on the delay-Doppler two-dimensional map obtained by 2D-FFT processing of the echo signal, the CFAR is used to calculate the power of the perceived target-related signal by taking the maximum amplitude sample point that exceeds the threshold of the CFAR as the target sample point and its amplitude as the target signal amplitude;

[0111] CFAR is performed based on the delay-Doppler-angle three-dimensional graph obtained by 3D-FFT processing of the echo signal, and the maximum amplitude sample point of CFAR over the threshold is used as the target sample point, and its amplitude is used as the target signal amplitude to calculate the perceived target associated signal power;

[0112] In addition to the above method of using the maximum amplitude sample point of CFAR over-threshold as the target sample point, the method of determining the target signal amplitude can also be to use the maximum amplitude sample point of CFAR over-threshold and the average of several of its nearest over-threshold sample points as the target signal amplitude to calculate the perceived target associated signal power.

[0113] The method for obtaining the SNR / SINR of the echo signal may be at least one of the following options:

[0114] CFAR is performed based on the one-dimensional delay graph obtained by fast time dimension FFT processing of the echo signal. The maximum amplitude sample point that exceeds the CFAR threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude. All sample points in the one-dimensional graph that are ±ε sample points away from the target sample point are taken as interference / noise sample points, and their average interference / amplitude is counted as the interference / noise signal amplitude. Finally, the SNR / SINR is calculated based on the target signal amplitude and the interference / noise signal amplitude.

[0115] CFAR is performed based on the Doppler one-dimensional image obtained by slow time dimension FFT processing of the echo signal. The maximum amplitude sample point of the CFAR threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude. All sample points in the one-dimensional image other than ±η sample points from the target sample point are taken as interference / noise sample points, and their average amplitude is counted as the interference / noise signal amplitude. Finally, the SNR / SINR is calculated based on the target signal amplitude and the interference / noise signal amplitude.

All sample points in the two-dimensional map that are ±ε (fast time dimension) and ±η (slow time dimension) away from the target sample point are taken as interference / noise sample points, and their average amplitude is counted as the interference / noise signal amplitude. Finally, the SNR / SINR is calculated based on the target signal amplitude and the interference / noise signal amplitude;

[0117] CFAR is performed based on the delay-Doppler-angle three-dimensional graph obtained by 3D-FFT processing of the echo signal. The maximum amplitude sample point that exceeds the CFAR threshold is taken as the target sample point, and its amplitude is taken as the target signal amplitude. All sample points in the three-dimensional graph that are ±ε (fast time dimension), ±η (slow time dimension) and ±δ (angle dimension) away from the target sample point are taken as interference / noise sample points, and their average amplitude is counted as the interference / noise signal amplitude. Finally, the SNR / SINR is calculated using the target signal amplitude and the interference / noise signal amplitude.

[0118] In addition to the above method of using the maximum amplitude sample point of CFAR over-threshold as the target sample point, the target signal amplitude can also be determined by using the maximum amplitude sample point of CFAR over-threshold and the average of several adjacent over-threshold sample points as the target signal amplitude;

For example, the measurement event indicates an event in which the second device is able to perform a perception measurement switch, or the measurement event indicates an event in which the first device decides to perform a perception measurement switch, etc.

[0125] Since the measurement report carries the above measurement event information, the overhead of the measurement report can be saved, such as carrying the identification or indication information of the measurement event.

[0126] Optionally, the event information associated with the measurement result of the perception measurement quantity includes: event information of a perception measurement quantity event, where the perception measurement quantity event is that the measurement result of the perception measurement quantity satisfies a first condition;

[0131] In this implementation, it is possible to indicate the measurement event in the measurement report, thereby saving measurement report overhead.

[0132] In some embodiments, the source node or the second device determines whether the corresponding measurement event is satisfied based on the average value of multiple measurement quantities or indicators at different times (such as layer 1 filtering or layer 3 filtering), or based on whether the values ​​of the measurement quantities or indicators measured multiple times in succession meet preset conditions, thereby avoiding the randomness / ping-pong effect caused by judging based on a single result.

[0140] The measurement result of the perception measurement quantity includes at least one of the above items, which may be defined by a protocol or configured on the network side, or indicated by the first device.

[0141] In this implementation, the second device can flexibly indicate the at least one distance to the first device, so that the first device can better decide whether to perform measurement switching.

[0299] When the first device receives the end perception indication information sent by the core network element, the first device ends the measurement operation;

[0300] When the first device receives the end perception indication information sent by the second device, the first device ends the measurement operation.

[0301] The above-mentioned perception measurement feedback information is a perception measurement result obtained by the second device performing perception measurement on the perception target, wherein the above-mentioned perception measurement feedback information may be measurement feedback information fed back after the second device performs one or more perception measurements.

[0302] In some implementations, the above-mentioned perception measurement feedback information may be measurement feedback information fed back after the measurement result of the second device meets corresponding conditions, such as a measurement performance indicator exceeding a preset threshold.

[0303] In this implementation, the measurement operation may be terminated only after the above-mentioned perception measurement feedback information or the perception termination indication information is received, so that the perception measurement switching may have better continuity, thereby improving the perception measurement performance.

[0304] For example: after the source node sends a switching command to the second device, the second device performs a self-transmitting and self-receiving sensing measurement based on the second signal, or the second device performs a self-transmitting and self-receiving sensing measurement based on the third signal. After the second device completes at least one sensing measurement and obtains a sensing result (optionally, and the corresponding first performance indicator exceeds a preset threshold value), the second device sends feedback information to the source node, and the source node ends the sensing measurement operation, stops sending the first signal, and releases the occupied resources.

[0305] As an optional implementation manner, the first device is the core network element, and after the first device sends the switching command to the second device, the method further includes:

[0306] The first device sends end perception indication information to the source node.

[0307] In this implementation, the core network element can instruct the source node to end the perception measurement after sending the switching command, so as to save the power consumption of the source node.

[0308] Optionally, the first device sending the end perception indication information to the source node includes:

[0309] In a case where the first device receives the perception measurement feedback information sent by the second device, the first device sends end perception indication information to the source node.

[0310] The above-mentioned perception measurement feedback information refers to the above-mentioned implementation manner and will not be described in detail here.

[0311] In this implementation, it is possible to instruct the source node to end the measurement operation only after receiving the above-mentioned perception measurement feedback information, so that the perception measurement switching can have better continuity, thereby improving the perception measurement performance.

[0312] For example: after the first device sends a switching command to the second device, it sends an end perception indication message to the source node, instructing the source node to end the perception measurement operation, stop sending the first signal, and release the occupied resources (including time-frequency resources, antenna port resources, etc.); the second device performs autonomous transmission and reception perception measurement based on the second signal, or the target node performs autonomous transmission and reception perception measurement based on the third signal.

[0313] For another example: after the first device sends a switching command to the second device, the second device performs a self-transmitting and self-receiving sensing measurement based on the second signal, or the second device performs a self-transmitting and self-receiving sensing measurement based on the third signal. After the second device completes at least one sensing measurement and obtains a sensing result (optionally, and the corresponding first performance indicator exceeds a preset threshold value), the first device sends an end sensing indication message to the source node, instructing the source node to end the sensing measurement operation, stop sending the first signal, and release the occupied resources.

[0314] In some implementations, after sending the switching command, end perception indication information may be sent to the source node.

[0315] In an embodiment of the present application, a first device obtains a measurement report fed back by a second device; when determining to switch the perception measurement based on the measurement report, the first device sends a switching command to the second device, and the switching command is used to switch the perception measurement of the perception target from the source node to the second device. In this way, by sending the switching command to the second device, it is supported to switch the perception measurement of the perception target from the source node to the second device, so as to improve the perception measurement performance.

The following steps are included:

[0381] Step 1: Trigger the measurement.

[0382] The source node transmits a signal (which may be referred to as the fourth signal) and receives an echo signal for perception measurement.

[0408] Among them, the source node or the candidate target node can judge whether the measurement event is satisfied, and can judge according to the average value of multiple measurement quantities / indicators at different times (layer 1 filtering or layer 3 filtering), or the value of the measurement quantity / indicator measured multiple times in succession meets the preset conditions, so as to avoid the randomness / ping-pong effect caused by judging according to a single result.

[0409] Determine the candidate target nodes based on their status information, wherein the status information may be sent by the candidate target nodes to the source node or the first device, and the source node or the first device determines a list of candidate target nodes based on the status information of the candidate target nodes; or the source node obtains the list of candidate target nodes from the first device.

[0417] Step 2: Perform the measurement

[0418] After receiving the switching measurement configuration information, the candidate target node performs switching measurement based on the first signal or the second signal, and feeds back a switching measurement report to the first device or the source node; the switching measurement report includes at least one of the value of the perceived measurement amount, the value of the first performance indicator, and an identifier that satisfies the corresponding measurement event.

[0419] Among them, the fourth signal and the first signal can be the same signal, that is, the source node transmits the fourth signal and receives the echo signal for perception measurement; the candidate target node receives the fourth signal, and transmits the second signal and receives the echo signal of the second signal for switching measurement. When the fourth signal and the first signal are the same signal, that is, the configuration information of the first signal is the configuration information of the fourth signal.

[0420] The fourth signal and the first signal can be different signals, that is, the source node transmits the fourth signal and receives the echo signal for perception measurement. When the first trigger event is met, the source node sends the first signal, the candidate target node receives the first signal, and transmits the second signal and receives the echo signal of the second signal for switching measurement.

[0421] Optionally, at least two of the fourth signal, the first signal, and the second signal adopt frequency division multiplexing, time division multiplexing, or code division multiplexing.

[0422] Step 3: Switch Verdict

[0423] The source node decides whether to initiate a handover based on the handover measurement report reported by the candidate target node.

[0424] Optionally, the source node receives a switching measurement report from the candidate target node and reports the switching measurement report to the first device, and the first device decides whether to initiate a switching request; or the first device decides whether to initiate a switching based on the switching measurement report received from the candidate target node.

[0425] If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, the source node still performs the perception measurement based on the self-transmitted and self-received fourth signal, or the source node stops the perception measurement.

[0426] If a handover is initiated, the source node or the first device determines a candidate target node and sends a handover request message thereto, requesting the at least one candidate target node to perform a perception measurement.

[0435] Switching type, including hard switching and soft switching.

[0436] Step 4: Perform the Switch

[0437] After receiving the handover request message, the candidate target node decides whether to accept the handover / execute the perception. There are two cases:

[0438] If agreed, the candidate target node sends a switching response message to the switching request information sender (source node or first device), and the switching response message is used to indicate to the switching request information sender that the candidate target node agrees to perform the perception measurement. Optionally, the candidate target node feeds back the recommended second signal configuration information in the switching response information, and the second signal configuration information is used for the signal configuration of the candidate target node to perform the perception measurement.

[0439] If not agreed, the candidate target node sends a switching rejection message to the switching request information sender (source node or first device), wherein the switching rejection message is used to indicate to the switching request information sender that the switching information sender is rejected and no perception is performed.

[0440] Subsequent processing can be one of the following:

[0441] The source node or the first device re-determines the candidate target node;

[0442] Maintain current perception;

[0443] End the current perception.

[0444] After receiving the handover response information, the source node or the first device determines at least one target node from the candidate target nodes as a device for performing perception measurement after the handover, and the source node or the first device sends a handover command to the target node to notify the target node to perform the perception measurement;

[0445] Specifically, the following situations are included:

[0446] After the source node sends a switching command to the candidate target node, the sensing measurement operation is terminated, the fourth signal and the first signal are stopped, and the occupied resources (including time-frequency resources, antenna port resources, etc.) are released; the target node performs a self-transmitting and self-receiving sensing measurement based on the second signal, or the target node performs a self-transmitting and self-receiving sensing measurement based on the third signal. The second signal is a signal for performing a switching measurement, and the target node can reuse the signal for subsequent sensing measurements. The third signal is a new signal sent by the target node for sensing measurements;

[0447] After the first device sends a switching command to the candidate target node, it sends end perception indication information to the source node, instructing the source node to end the perception measurement operation, stop sending the fourth signal and the first signal, and release the occupied resources (including time-frequency resources, antenna port resources, etc.); the target node performs self-transmitting and self-receiving perception measurement based on the second signal, or the target node performs self-transmitting and self-receiving perception measurement based on the third signal;

[0448] After the source node sends a switching command to the candidate target node, the target node performs a self-transmitting and self-receiving sensing measurement based on the second signal, or the target node performs a self-transmitting and self-receiving sensing measurement based on the third signal. When the target node completes at least one sensing measurement and obtains a sensing result (optionally, and the corresponding first performance indicator exceeds a preset threshold value), the target node sends feedback information to the source node, and the source node ends the sensing measurement operation, stops sending the fourth signal and the first signal, and releases the occupied resources;

[0449] After the first device sends a switching command to the candidate target node, the target node performs a self-transmitting and self-receiving sensing measurement based on the second signal, or the target node performs a self-transmitting and self-receiving sensing measurement based on the third signal. After the target node completes at least one sensing measurement and obtains a sensing result (optionally, and the corresponding first performance indicator exceeds a preset threshold value), the first device sends an end sensing indication message to the source node, instructing the source node to end the sensing measurement operation, stop sending the fourth signal and the first signal, and release the occupied resources.

[0450] Embodiment 2:

[0451] In this embodiment, based on Figure 3 The sensing link 302 shown in the figure performs switching measurement, and in this embodiment, the source node senses by self-transmitting and self-receiving signals, and then switches to the target node self-transmitting and self-receiving sensing by judging the source node's self-transmitting and self-receiving, and the source node sending and receiving the candidate target node's sensing results. Compared with the first embodiment, during the switching measurement, there is no need for the candidate target node to actively send signals and receive echoes for measurement. It includes the following steps:

[0452] Step 1: Trigger the measurement

[0453] The source node transmits a fourth signal and receives an echo signal to perform perception measurement, and when the first trigger event is met, sends switching measurement configuration information to the candidate target node (optionally, the first device of the core network (see Explanation 1) may also send the switching measurement configuration information to the candidate target node);

[0464] The value of at least one first performance indicator obtained based on the measurement of the first signal meets a preset condition, for example, the RSRP, RSRQ or SNR obtained based on the measurement of the first signal exceeds a preset threshold.

[0465] Toggles measurement assistance information.

[0466] Step 2: Perform the measurement

[0467] After receiving the switching measurement configuration information, the candidate target node performs switching measurement based on the first signal, and feeds back a switching measurement report to the first device of the core network or the source node; the switching measurement report includes at least one of the value of the perceived measurement quantity, the value of the first performance indicator, and an identifier that satisfies the corresponding measurement event.

[0468] The fourth signal and the first signal may be the same signal, that is, the source node transmits the fourth signal and receives the echo signal to perform perception measurement; the candidate target node receives the fourth signal to perform switching measurement.

[0469] The fourth signal and the first signal may be different signals, that is, the source node transmits the fourth signal and receives the echo signal for perception measurement. When the first trigger event is met, the source node sends the first signal, and the candidate target node receives the first signal for switching measurement.

[0470] Step 3: Switch Verdict

[0471] The source node decides whether to initiate a handover based on the handover measurement report reported by the candidate target node.

[0472] Optionally, the source node receives a switching measurement report from the candidate target node and reports the switching measurement report to the first device, and the first device decides whether to initiate a switching request; or the first device decides whether to initiate a switching request based on the switching measurement report received from the candidate target node.

[0473] If the handover is not initiated, the subsequent processing may be to maintain or end the current perception measurement, that is, the source node still performs the perception measurement based on the self-transmitted and self-received fourth signal, or the source node stops the perception measurement.

[0474] If a handover is initiated, the source node or the first device determines a candidate target node and sends a handover request message thereto, requesting the at least one candidate target node to perform a perception measurement.

[0475] The handover request information definition and the method for determining the candidate target node are the same as those in the first embodiment and are not described in detail here.

[0476] Step 4: Perform the Switch

[0477] After receiving the handover request message, the candidate target decides whether to accept the handover / execute the perception. There are two cases:

[0478] If agreed, the candidate target node sends a switching response message to the handover request message sender (source node or first device), and the switching response message is used to indicate to the handover request message sender that it agrees to perform the perception measurement. Optionally, the candidate target node feeds back the recommended second signal configuration information in the handover response message. The second signal configuration information is used for the signal configuration of the candidate target node to perform the perception measurement.

[0479] If not agreed, the candidate target node sends a switching rejection message to the switching request information sender (source node or first device), wherein the switching rejection message is used to indicate to the switching request information sender that the switching information sender is rejected and no perception is performed.

[0480] Subsequent processing can be one of the following:

[0481] The source node or the first device re-determines the candidate target node;

[0482] Maintain current perception;

[0483] End the current perception.

[0484] After receiving the handover response information, the source node or the first device determines at least one target node from the candidate target nodes as a device for performing perception measurement after the handover, and the source node or the first device sends a handover command to the target node to notify the target node to perform the perception measurement;

[0485] Specifically, the following situations are included:

[0486] After the source node sends a switching command to the candidate target node, the sensing measurement operation is terminated, the fourth signal and the first signal are stopped, and the occupied resources (including time-frequency resources, antenna port resources, etc.) are released; the target node performs self-transmitting and self-receiving sensing measurement based on the second signal;

[0487] After the first device sends a switching command to the candidate target node, it sends end perception indication information to the source node, instructing the source node to end the perception measurement operation, stop sending the fourth signal and the first signal, and release the occupied resources (including time-frequency resources, antenna port resources, etc.); the target node performs self-transmitting and self-receiving perception measurement based on the second signal;

[0488] After the source node sends a switching command to the candidate target node, the target node performs a self-transmitting and self-receiving sensing measurement based on the second signal. When the target node completes at least one sensing measurement and obtains a sensing result (optionally, and the corresponding first performance indicator exceeds a preset threshold value), the target node sends feedback information to the source node, and the source node ends the sensing measurement operation, stops sending the fourth signal and the first signal, and releases the occupied resources;

[0489] After the first device sends a switching command to the candidate target node, the target node performs a self-transmitting and self-receiving sensing measurement based on the second signal. When the target node completes at least one sensing measurement and obtains a sensing result (optionally, and the corresponding first performance indicator exceeds a preset threshold value), the first device sends an end sensing indication message to the source node, instructing the source node to end the sensing measurement operation, stop sending the fourth signal and the first signal, and release the occupied resources.

[0490] Embodiment three:

[0491] In this embodiment, based on Figure 3 The sensing link 301 and the sensing link 302 shown trigger the switching measurement

[0492] In this embodiment, the source node performs sensing measurements based on sensing link 301 and sensing link 302, and determines whether to initiate a switching process. The following steps are included:

[0493] Step 1: Trigger the measurement

[0494] The source node transmits a fourth signal and receives an echo signal to perform perception measurement to obtain a first measurement result. At the same time, the candidate target node receives the first signal sent by the source node to perform perception measurement to obtain a second measurement result, and feeds back the second measurement result to the source node or the first device. The first / second measurement result includes at least one of the value of the perception measurement quantity and the value of the first performance indicator.

[0495] When the first trigger event is met, the source node sends the switching measurement configuration information to the candidate target node, and optionally, the first device of the core network sends the switching measurement configuration information to the candidate target node;

[0496] The first triggering event includes at least one of the following:

[0497] Event 1: A first measurement result obtained by the source node based on the measurement of the fourth signal reaches a preset threshold, or a second measurement result obtained by the candidate target node based on the measurement of the first signal reaches a preset threshold, or a specific relationship is satisfied between the first measurement result and the second measurement result, and the first / second measurement result includes at least one of the following:

[0498] The value of the perceived measurement quantity. The value of the perceived measurement quantity reaching the preset threshold may be, for example, that the distance d1 between the perceived target and the source node exceeds a preset value; or, the distance d2 between the perceived target and the candidate target node is lower than a preset value; or, d1-d2 exceeds a preset value; or, the position coordinates of the perceived target meet a specific condition, i.e., are located in a specific area; or, the movement speed of the perceived target exceeds a preset value;

[0499] The value of the first performance indicator. The first performance indicator includes at least one of the following:

[0500] Fourth signal received power (e.g., RSRP, RSRQ, RSSI), SNR or SINR;

[0501] Perceived received power, perceived SNR, or perceived SINR.

[0502] The first performance indicator reaching the preset threshold value may be, for example, that the RSRP or SNR measured based on the fourth signal is less than a preset value (optionally, the RSRP or SNR measured for multiple consecutive times may be less than the preset value); or the RSRP or SNR measured based on the first signal is less than a preset value (optionally, the RSRP or SNR measured for multiple consecutive times may be less than the preset value); or the SNR measured based on the first signal is ≥ (γ*SNR measured based on the fourth signal), where γ is a scaling factor.

[0503] Event 2: The communication index of the source node reaches a preset threshold. The communication index includes at least one of the following: bit error rate, block error rate, bit error rate, throughput, spectrum efficiency, etc.

[0504] Event 3: The available sensing resources of the source node change. For example, if other high-priority sensing / communication / synaesthesia services suddenly occur, it is necessary to evaluate whether to initiate the sensing switching process based on the remaining available sensing resources.

[0505] Event 4: The source node receives a perception switching instruction or an instruction to stop providing perception services from the first device in the core network.

[0506] In addition to the method in Example 1, the determination of the candidate target node in this embodiment also includes: judging based on the second measurement result, for example, satisfying the distance d2 between the candidate target node and the perception target ≤ the preset value, or the sum of the distance from the source node to the perception target and the distance from the perception target to the candidate target node d1+d2 ≤ the preset value, or taking the perception node with RSRP ≥ the preset value obtained based on the first signal measurement as the candidate target node, or taking the N perception nodes with the largest RSRP obtained based on the first signal measurement as the candidate target nodes.

[0507] Step 2: Perform the measurement.

[0508] Step 3: Switch judgment.

[0509] Step 4: Perform the switch.

[0510] Among them, step 2, step 3 and step 4 can refer to embodiment 1 and are not described in detail here.

[0511] In order to ensure the continuity of perception services for mobile targets and improve perception switching performance, in the embodiment of the present application, during the process of switching from the spontaneous and self-receiving perception of perception device A to the spontaneous and self-receiving perception of perception device B, the A-B-receiving perception link is used for joint perception, and the perception results of A-B-receiving and the spontaneous and self-receiving perception results are used together as switching conditions, which can ensure the perception performance during the switching process and reduce the perception context interaction overhead.
