The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0041] Reference Figure 1 , Figure 1 It is a schematic diagram of an application scenario of a perception method in an embodiment of the present application.

[0042] like Figure 1 As shown, the method provided in the embodiment of the present application can be applied to the multi-station sensing scenario, wherein the multi-station sensing refers to obtaining the sensing result through the collaboration between multiple communication devices.

[0043] like Figure 1 As shown, the first communication device is the sender of the perception signal, and the second communication device is the receiver of the perception signal.

[0044] Specifically, the first communication device may send a perception signal, the second communication device may receive the perception signal, and perform perception according to the received perception signal.

[0045] The perception signal may be a defined reference signal, such as a channel state information reference signal (CSI-RS), a synchronization signal block (SSB), a positioning reference signal (PRS), or a sounding reference signal (SRS). Alternatively, the perception signal may also be a newly defined reference signal, which is not limited in this embodiment.

[0046] It should be noted that the perception signal received by the second communication device may be the perception signal itself sent by the first communication device, that is, the perception signal sent by the first communication device may be sent directly to the second communication device without passing through any object; the perception signal received by the second communication device may also be a signal formed by hitting the target, for example, a reflection signal, etc., and the embodiment of the present invention does not impose any restrictions on this. In a specific implementation, the first communication device may be a network device, and the second communication device may be a terminal; or the first communication device may be a first terminal, and the second communication device may be a second terminal; or the first communication device may be a first network device, and the second communication device may be a second network device; or the first communication device may be a terminal, and the second communication device may be a network device.

[0047] In addition, the solution of the embodiment of the present application can be applied to the scenario of single-station perception, where the single-station perception is to obtain the perception result through the self-transmission and self-reception of the same communication device. Specifically, the first communication device can send a perception signal and measure the perception signal sent by itself to obtain the perception result. The communication device that performs single-station perception can be a terminal or a network device.

[0048] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0049] Reference Figure 2 , Figure 2 is a flow chart of a sensing method in an embodiment of the present application. In a multi-station sensing scenario, Figure 2 The method shown can be applied to the second communication device described above, or, Figure 2 The illustrated method may be applied to a communication device that performs single-station awareness.

[0050] Figure 2 The method shown may include S21 and S22. In this application, S in each step number represents a step.

[0051] S21, measuring a first perception signal;

[0052] S22: In response to at least one of the measurement results of the first perception signal satisfying a reporting condition, send a first perception report.

[0053] In a multi-station perception scenario, in S21, the first communication device sends a first perception signal, and accordingly, the second communication device receives the first perception signal and measures the first perception signal to obtain a measurement result of the first perception signal. In S22, in response to at least one measurement result of the first perception signal satisfying a reporting condition, the second communication device sends a first perception report to the first communication device. Specifically, the second communication device may determine whether various measurement results of the first perception signal meet the reporting condition, and in response to at least one measurement result of the first perception signal satisfying the reporting condition, the second communication device may send a first perception report to the first communication device. In a specific implementation, the first perception signal may include multiple perception signals, wherein the multiple perception signals may be configured at different time domain positions and / or frequency domain positions. Exemplarily, the first perception signal may be a group of periodic perception signals.

[0054] The measurement result of the first perception signal is obtained by measuring the first perception signal. Specifically, the measurement result of the first perception signal may include at least one of the following: arrival time of at least one perception signal in the first perception signal, arrival time difference between perception signals in the first perception signal, Doppler information of at least one perception signal in the first perception signal, channel quality information corresponding to at least one perception signal in the first perception signal, and measurement time of at least one perception signal in the first perception signal.

[0055] The channel quality information may be any one of the following: reference signal receiving power (RSRP), signal-to-noise and interference ratio (SINR), or reference signal received quality (RSRQ), but is not limited thereto. In addition, the measurement time may refer to the time or measurement duration of measuring the perception signal.

[0056] In S22, in response to a measurement result of at least one first perception signal satisfying a reporting condition, the second communication device sends a first perception report to the first communication device.

[0057] Exemplarily, if any measurement result of the first perception signal satisfies a reporting condition corresponding to the measurement result, the second communication device sends a first perception report to the first communication device.

[0058] Also exemplarily, when one or more specific measurement results of the first perception signal meet their respective corresponding reporting conditions, the second communication device sends a first perception report to the first communication device.

[0059] In a specific implementation, the reporting condition may be a value range, and satisfying the reporting condition may mean that the actual measurement result belongs to the corresponding value range. Specifically, for each measurement result, the second communication device may determine whether the measurement result is within the value range corresponding to the measurement result, and if the determination result is yes, the second communication device may determine that the measurement result satisfies the reporting condition.

[0060] Taking RSRP as an example, if the RSRP actually measured is greater than or equal to the received power threshold, it can be determined that the RSRP meets the reporting condition.

[0061] In the solution of the embodiment of the present application, the second communication device sends a first perception report to the first communication device to inform the first communication device that a target object is perceived or a target event is detected.

[0062] In one embodiment of the present application, the first perception report may include: notification information, which may be used to notify the first communication device that a target event is perceived or detected. Taking the application scenario of intrusion detection as an example, if at least one of the measurement results of the first perception signal meets the reporting condition, the second communication device may determine that an intrusion is perceived, thereby sending a first perception report to the first communication device to inform the first communication device that an intrusion event is detected.

[0063] In a specific implementation, the first perception report may include: at least one of the measurement results of the first perception signal. Specifically, the first perception report may include at least one of the following: the arrival time of at least one perception signal in the first perception signal, the arrival time difference between the perception signals in the first perception signal, the arrival angle of at least one perception signal in the first perception signal, the Doppler information of at least one perception signal in the first perception signal, and the channel quality information corresponding to at least one perception signal in the first perception signal.

[0064] In an embodiment of the present application, the first perception report may further include at least one of the following: resource index information of at least one perception signal in the first perception signal, and a measurement time corresponding to the first perception report. The perception signal corresponding to the resource index information in the first perception report may be a perception signal whose measurement result meets the reporting condition in the first perception signal, and the measurement time corresponding to the first perception report may be the measurement time of the perception signal that meets the reporting condition in the first perception signal.

[0065] In another embodiment of the present application, the first perception report may include the perceived physical state of the object, the position of the object, the motion state (such as the moving speed, etc.), the distance between the object and the second communication device, etc. The physical state of the object may be calculated based on the measurement result of the first perception signal.

[0066] Further, the first perception report may be sent via a physical layer channel or a high-layer signaling. For example, the second communication device is a terminal, the first communication device is a network device, and the first perception report may be carried on a physical random access channel (PRACH), or carried on a physical uplink control channel (PUCCH), or carried on a medium access control-control element (MAC CE) signaling.

[0067] Therefore, in the above scheme, in the multi-station perception scenario, when the second communication device determines that at least one measurement result of the first perception signal meets the reporting conditions, it sends a first perception report to the first communication device. This not only enables the first communication device to promptly know that the second communication device perceives the target event or target object, but also enables it to further configure a more reasonable perception signal for subsequent perception based on the content of the first perception report.

[0068] In the single-station perception scenario, in S21, the third communication device may send and receive a first perception signal, and measure the received first perception signal to obtain a measurement result of the first perception signal.

[0069] In S22, the third communication device sends or reports a first perception report in response to at least one of the measurement results of the first perception signal satisfying a reporting condition.

[0070] Exemplarily, if any measurement result of the first perception signal satisfies a reporting condition corresponding to the measurement result, the third communication device may send a first perception report to the fourth communication device.

[0071] Also exemplarily, if one or more specific measurement results of the first perception signal meet their respective corresponding reporting conditions, the third communication device sends a first perception report to the fourth communication device.

[0072] In the solution of the embodiment of the present application, the third communication device sends a first perception report to the fourth communication device, which can promptly inform the fourth communication device that the target object is perceived or the target event is detected.

[0073] In a specific implementation, if the third communication device is a terminal, the fourth communication device is an access network device. If the third communication device is an access network device, the fourth communication device is a core network device. In an application scenario where a communication device is used for perception, in order to ensure the real-time nature of perception, the second communication device needs to continuously perform perception measurements. In addition, in order to ensure the accuracy of perception, it is expected that the perception signal can occupy more time-frequency resources. However, in some scenarios, when the probability of occurrence of the perception target is low, continuously measuring the perception signal that occupies more time-frequency resources will cause a waste of resources.

[0074] For example, in the scenario of intrusion monitoring, the probability of an intruder as a perception target is low. On the one hand, it will lead to an increase in the complexity and energy consumption of terminal measurement. If the network device configures the terminal to continuously measure and report high-precision perception results, not only will the time-frequency resource overhead of the perception signal be large, but it will also lead to an increase in the complexity and energy consumption of terminal measurement. To this end, in one embodiment of the present application, a first perception signal is first used for preliminary perception, and when the target is perceived, the perception of the second perception signal is triggered to obtain a high-precision perception result.

[0075] After S12, the measuring communication device may measure the second perception signal. The measuring communication device may refer to a device that measures the second perception signal, for example, the second communication device or the third communication device.

[0076] In an embodiment of the present application, the second perception signal may be configured according to the first perception report. In other words, the first perception report may be used at least to configure the second perception signal.

[0077] Exemplarily, the communication device (such as the first communication device or the fourth communication device) that receives the first perception report may configure the second perception signal to the measuring communication device.

[0078] As another example, the measuring communication device may configure the second perception signal based on the first perception report.

[0079] Furthermore, by measuring the second perception signal, a second perception report may be generated. In the solution of the embodiment of the present application, the accuracy of the second perception report is higher than the accuracy of the first perception report.

[0080] For more information about the second perception signal and the second perception report, please refer to the relevant description below.

[0081] Reference Figure 3 , Figure 3 It is a flowchart of another perception method in an embodiment of the present application. Figure 3 The method shown can be applied to the second communication device or the third communication device mentioned above. Figure 3The method shown may include: S31 to S33.

[0082] S31, measuring a first perception signal.

[0083] S32: In response to at least one of the measurement results of the first perception signal satisfying a reporting condition, sending a first perception report, and measuring a second perception signal.

[0084] S33, sending a second perception report.

[0085] For details about sending the first perception report in S31 and S32, please refer to the above Figure 2 The relevant description will not be repeated here.

[0086] In a specific implementation, after determining that at least one of the measurement results of the first perception signal meets the reporting condition, the first perception report is sent within a preset time period. That is, the measuring communication device reports the first perception report immediately after determining that the target is perceived.

[0087] In addition, when at least one of the measurement results of the first perception signal meets the reporting condition, in the solution of this embodiment, the measuring communication device also measures the second perception signal. Specifically, in response to at least one of the measurement results of the first perception signal meeting the reporting condition, the measuring communication device measures the second perception signal.

[0088] It should be noted that this embodiment does not limit the order of measuring the communication device sending the first perception report and measuring the second perception signal.

[0089] As a possible implementation manner, the measuring communication device may first measure the second perception signal and then send the first perception report.

[0090] As another possible implementation manner, the measuring communication device may first send a first perception report and then measure the second perception signal.

[0091] As another possible implementation, the measuring communication device may simultaneously measure the second perception signal and send the first perception report. Specifically, the second perception signal may include multiple perception signals, wherein the multiple perception signals may be configured at different time domain positions and / or frequency domain positions. Exemplarily, the second perception signal may be a group of periodic perception signals.

[0092] In one embodiment of the present application, the second perception signal may be the same as the first perception signal. Specifically, the second perception signal may be CSI-RS, SSB, PRS, but is not limited thereto. The type of the second perception signal may be the same as the type of the first perception signal, or the type of the second perception signal may be different from the type of the first perception signal. In addition, the configuration of the second perception signal may be the same as the configuration of the first perception signal.

[0093] Further, in S32, when the configuration of the second perception signal is the same as the configuration of the first perception signal, the measurement method of the second perception signal may be more complex than the measurement method of the first perception signal. In other words, the measuring communication device measures the second perception signal in a more complex measurement manner to obtain a higher precision measurement result.

[0094] In another embodiment of the present application, compared with the first perception signal, the second perception signal occupies more time-frequency resources. In other words, the resource overhead of the second perception signal may be greater than the resource overhead of the first perception signal. Since the resource overhead of the second perception signal is greater than the resource overhead of the first perception signal, a more accurate perception result can be obtained by measuring the second perception signal.

[0095] More specifically, the resource overhead of the second perception signal being greater than the resource overhead of the first perception signal may include at least one of the following:

[0096] (1) The bandwidth of the second perception signal is greater than the bandwidth of the first perception signal;

[0097] Specifically, the bandwidth of the second perception signal is greater than the bandwidth of the first perception signal, and a more accurate perception distance can be obtained by measuring the second perception signal.

[0098] (2) The frequency domain density of the second perception signal is greater than the frequency domain density of the first perception signal;

[0099] Specifically, the frequency domain density of the second perception signal is greater than the frequency domain density of the first perception signal, so that the perception range of the second perception signal can be greater than the perception range of the first perception signal.

[0100] (3) The time domain interval of the second perception signal is smaller than the time domain interval of the first perception signal;

[0101] In other words, the time domain density of the second perception signal is greater than the time domain density of the first perception signal. Exemplarily, the second perception signal may be a group of periodic perception signals, and the period of the second perception signal is less than the period of the first perception signal.

[0102] In a specific implementation, the time domain interval of the second perception signal is smaller than the time domain interval of the first perception signal. By measuring the second perception signal, a more accurate perception speed can be obtained.

[0103] (4) The duration of the second perception signal is greater than the duration of the first perception signal;

[0104] Specifically, the duration of the second perception signal is greater than the duration of the first perception signal, and the range of perception speed obtained by measuring the second perception signal is greater than the range of perception speed of the first perception signal.

[0105] Further, the second communication device measures the second perception signal to obtain a measurement result of the second perception signal. In the solution of this embodiment, the resource overhead of the second perception signal may be greater than that of the first perception signal, and a more accurate measurement result may be obtained by measuring the second perception signal.

[0106] In a specific implementation, the measurement result of the second perception signal may include at least one of the following: the arrival time of at least one perception signal in the second perception signal, the arrival time difference between the perception signals in the second perception signal, the arrival angle of at least one perception signal in the second perception signal, the Doppler information of at least one perception signal in the second perception signal, and the channel quality information corresponding to at least one perception signal in the second perception signal.

[0107] In S33, the measuring communication device sends a second perception report.

[0108] Exemplarily, in response to obtaining a measurement result of the second perception signal, the second communication device may send a second perception report to the first communication device.

[0109] Also illustratively, in response to obtaining the measurement result of the second perception signal, the third communication device may send a second perception report to the fourth communication device.

[0110] In a specific implementation, the second perception report may include a measurement result of the second perception signal. Specifically, various measurement results of the second perception signal may be included in the second perception report.

[0111] More specifically, the second perception report may include at least one of the following: the arrival time of at least one perception signal in the second perception signal, the arrival time difference between the perception signals in the second perception signal, the arrival angle of at least one perception signal in the second perception signal, the Doppler information of at least one perception signal in the second perception signal, and the channel quality information corresponding to at least one perception signal in the second perception signal.

[0112] In an embodiment of the present application, the second perception report may further include at least one of the following: resource index information of at least one perception signal in the second perception signal, measurement time corresponding to the second perception report, etc. The perception signal corresponding to the resource index information in the second perception report may be a perception signal corresponding to the measurement result in the second perception report, and the measurement time corresponding to the second perception report may be a measurement time of the perception signal corresponding to the measurement result.

[0113] In a specific implementation, the second perception report may be sent via physical layer or high layer signaling.

[0114] From the above, the scheme of this embodiment reports the perception result twice, the first time reports the preliminary perception result through the first perception report, and the second time reports the high-precision perception result through the second perception report. The first perception signal is measured with low precision, and the high-precision measurement of the second perception signal is triggered when at least one measurement result of the first perception signal meets the reporting condition. For example, in an intrusion detection scenario, the first perception signal is used to monitor the intrusion event, and the second perception signal is triggered to measure the intrusion target after receiving the intrusion event report.

[0115] By adopting such a solution, it is possible to avoid continuously using perception signals with large resource overhead for measurement in order to obtain high-precision measurement results, which is beneficial to reducing the overall resource overhead of perception signals, or it is possible to avoid continuously using measurement methods with high complexity for measurement, which is beneficial to reducing the complexity and energy consumption of perception measurements.
