[0019] To make those skilled in the art better understand the technical solutions of the present disclosure, the embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0025] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configuration formed based on the manufacturing process. Therefore, the regions exemplified in the drawings have a schematic property, and the shape of the regions shown in the drawings exemplifies a specific shape of the region of the element, but is not intended to be restrictive.

[0026] At present, in the application scenario of sensing and communication integration, the communication device will send a sensing signal while communicating with other devices, to sense the environmental information around the communication device. The increase of the sensing signal will increase the energy consumption of the communication device.

[0027] In some related technologies, the base station switches between sensing mode and communication mode; in the sensing mode, the base station will send a sensing signal to the surrounding environment to sense whether there is a target device around; and in the communication mode, the base station will stop the transmission and reception of the sensing signal, resulting in the inability to dynamically and continuously sense the target device.

[0028] To solve the above problems, the present disclosure provides a target sensing method, an electronic device, a computer readable medium and a computer program product.

[0029] In a first aspect, the embodiments of the present disclosure provide a target sensing method.

[0030] Figure 1 A flowchart of a target sensing method provided by the embodiments of the present disclosure. The target sensing method is applied to a target sensing device, which can be arranged in a base station.

[0031] As shown in the figure, the target sensing method includes but is not limited to the following steps. Figure 1

[0032] Step S101, determining a configuration scheme of a sensing signal according to a sensing result.

[0033] The sensing result is information obtained by a wireless transmitting device sensing a target device within its sensing range, the sensing signal is a wireless signal used for sensing the target device, and the configuration scheme represents a way of carrying the sensing signal in a target sensing frame.

[0034] The configuration scheme of the sensing signal carried in the target sensing frame is a scheme of configuration information such as the format of the sensing signal, the number of the sensing signal and the type of the sensing signal.

[0035] The configuration scheme of the sensing signal is determined through the sensing result, so as to adjust the sensing signal carried in the target sensing frame using the configuration scheme, so that the adjusted target sensing frame is more suitable for sensing the target device.

[0036] In some embodiments, the target sensing frame can also carry a communication signal, and the transmission of the communication signal is performed at the same time as the sensing, so as to reuse the signal transmission channel and improve the utilization efficiency of the signal transmission channel.

[0037] Step S102, configuring the sensing signal based on the configuration scheme of the sensing signal to obtain a target sensing frame.

[0038] The number of the sensing signal carried in the sensing frame can be adjusted, and / or the type of the sensing signal can be adjusted, and / or the position of the sensing signal in the sensing frame can be adjusted, and / or other different configuration manners, so that the obtained target sensing frame is more suitable for sensing the target device.

[0039] Step S103, transmitting the target sensing frame to sense the target device and determine the position information of the target device.

[0040] ​The target perception frame carries a perception signal configured according to a configuration scheme. In the process of perception, the position information of the target device can be determined by the information carried by the reflection signal fed back by the target device.

[0041] In the process of perceiving the target device by sending the target perception frame, it can be determined whether the target device is perceived or the distance between the target device and the base station, and then the position information of the target device is determined according to the obtained perception information.

[0042] Further, when the target device is not perceived, the way in which the perception signal is carried in the target perception frame can also be dynamically adjusted, so that the adjusted target perception frame is more suitable for the perception of the target device and speeds up the perception of the target device.

[0043] In some embodiments, the target perception frame can be sent to the surrounding of the base station every interval of a preset time length. When the target device receives the perception signal carried in the target perception frame, it will feed back a reflection signal, which can carry the position information of the target device, so that the base station can determine the position information of the target device according to the information carried by the reflection signal.

[0044] The target perception method in the embodiments of the present disclosure dynamically determines the way in which the perception signal is carried in the target perception frame through the perception result, so that the perception signal carried in the target perception frame is more suitable for the perception of the target device. The target perception frame is obtained by dynamically configuring the perception signal based on the configuration scheme of the perception signal, so that the power consumption corresponding to the target perception frame is reduced to achieve the effect of energy saving. Moreover, the target perception frame is continuously sent in the embodiments of the present disclosure, so as to continuously perceive the target device. Compared with the scheme in the related art in which the transmission of the perception signal is stopped when the target device is perceived, the perception of the target device can be ensured to be continuous.

[0045] In some exemplary embodiments, the configuration scheme of the perception signal is determined according to the perception result, including: determining that the perception of the target device in the preset number of times in the perception result is not perceived, and adjusting the number and / or type of symbols in the perception signal carried in the target perception frame.

[0046] The perception result includes information of perceiving the target device for a preset number of times. After n times of perception of the target device by the perception signal carried in the target perception frame, n perception results can be obtained, and n is an integer greater than or equal to 1.

[0047] If at least one of the n perception results is that the target device is perceived, it means that the current target perception frame is suitable for the current perception environment, so the configuration scheme of the perception signal can be kept unchanged, and the target device can be continuously perceived by using the target perception frame subsequently.

[0048] If the n perception results are all that the target device is not perceived, it is necessary to adjust the configuration scheme of the perception signal: for example, adjusting the number and / or type of symbols in the perception signal carried by the target perception frame (such as increasing or decreasing the number of a certain type of symbol carried in the target perception frame, etc.); so that the adjusted target perception frame can be suitable for perceiving the target device in the current perception environment, and improve the perception accuracy of the target device.

[0049] By judging the n perception results as described above, and then changing or keeping unchanged the configuration scheme of the perception signal carried by the target perception frame according to the judgment result, the fine adjustment of the target perception frame can be realized, so as to more accurately perceive the target device.

[0050] In some exemplary embodiments, the symbols in the perception signal include pulse wave symbols and continuous wave symbols; adjusting the number and / or type of symbols in the perception signal carried by the target perception frame includes: reducing the number of continuous wave symbols carried by the target perception frame, and / or reducing the number of pulse wave symbols carried by the target perception frame.

[0051] Among them, the pulse (P) wave symbol has the characteristics of occupying full channel, large transmission power and long detection distance, and its perception accuracy is higher, which is suitable for perceiving the target device at a long distance. The continuous (C) wave symbol has the characteristics of continuously transmitting and receiving signals, and it does not have a perception blind area, which can meet the perception demand at a short distance.

[0052] For example, Figure 2 A structure diagram of a target perception frame is provided for the embodiments of the present disclosure. As shown in the figure, Figure 2 The target perception frame includes uplink communication signals, pulse wave symbols, continuous wave symbols, and downlink communication signals.

[0053] Among them, the pulse wave symbol includes mutually independent transmission signals and reception signals, while the continuous wave symbol includes transmission & reception signals, which are jointed together.

[0054] In the transmission process of the P wave symbol transmission, the transmission signals and reception signals are performed at intervals, and there is an invalid reception window between the transmission and reception of signals, which causes a perception blind area when perceiving at a short distance.

[0055] For example, Figure 3 A transmission and reception window diagram of a perception signal is provided for the embodiments of the present disclosure. As shown in the figure, Figure 3As shown, there is an invalid receiving window between the sending window and the receiving window, and the corresponding sensing distance of the invalid receiving window is generally a fixed distance (for example, 200 meters), thereby causing a sensing blind area in the near distance sensing process.

[0056] Although the C-wave symbol does not have a sensing blind area, since the C-wave symbol is simultaneously used for signal sending and receiving, the sending signal and the receiving signal will respectively occupy half of the channel; compared with the P-wave symbol, the corresponding transmission power is small, and the sensing accuracy is relatively low.

[0057] In some embodiments, the symbols in the sensing signal carried by the target sensing frame can be adjusted in any of the following ways to obtain an adjusted target sensing frame:

[0058] 1) reducing the number of continuous wave symbols carried by the target sensing frame, and keeping the number of pulse wave symbols carried by the target sensing frame unchanged, to obtain an adjusted target sensing frame;

[0059] 2) reducing the number of pulse wave symbols carried by the target sensing frame, and keeping the number of continuous wave symbols carried by the target sensing frame unchanged, to obtain an adjusted target sensing frame;

[0060] 3) reducing the number of pulse wave symbols carried by the target sensing frame, and reducing the number of continuous wave symbols carried by the target sensing frame at the same time, to obtain an adjusted target sensing frame.

[0061] In the process of reducing the number of symbols of each different type, the number of symbols can be reduced one by one or a plurality of symbols can be reduced at one time, that is, the number of symbols to be reduced is adjusted according to the actual sensing situation, and the present disclosure does not limit this.

[0062] By sampling the above different adjustment methods, the number of pulse wave symbols and / or the number of continuous wave symbols in the sensing signal carried by the target sensing frame are adjusted, so that the pulse wave symbols and the continuous wave symbols can play their respective sensing characteristics to sense the target device in different distance ranges and improve the sensing accuracy.

[0063] In some exemplary embodiments, the method further comprises: determining that the number of pulse wave symbols carried by the target sensing frame is 1 and / or the number of continuous wave symbols is 1; and stopping sensing the target device if the target device is not sensed within a preset time period after sending the target sensing frame.

[0064] When the number of pulsed wave symbols carried by the target sensing frame is one, or the number of continuous wave symbols carried by the target sensing frame is one, or both the number of pulsed wave symbols and the number of continuous wave symbols carried by the target sensing frame are one, if the target device is still not sensed when the target device is sensed by the sensing signal carried by the target sensing frame, it indicates that there is no target device around the base station, and at this time, the sensing of the target device can be stopped to save communication resources.

[0065] In some example embodiments, the method further comprises: determining that the configuration scheme of the sensing signal changes, and adjusting the sending period of the target sensing frame.

[0066] If the configuration scheme of the sensing signal changes, for example, the number of a certain type of symbol is reduced, or the number of a certain type of symbol is increased, the sending period of the target sensing frame needs to be adjusted correspondingly, so that there is enough time for sensing in the process of sensing the target device by the target sensing frame carrying the sensing signal, thereby realizing the sensing accuracy of the target device.

[0067] For example, when the number of pulsed wave symbols carried in the target sensing frame is increased, it indicates that the target device far away from the base station needs to be sensed, and the sending period of the target sensing frame can be appropriately extended, thereby facilitating sufficient sensing of the target device far away from the base station to obtain the position information of the target device.

[0068] For another example, when the number of continuous wave symbols carried in the target sensing frame is increased, it indicates that the target device close to the base station needs to be sensed, and the sending period of the target sensing frame can be shortened to facilitate sensing the target device as soon as possible.

[0069] In some example embodiments, the symbols in the sensing signal include pulsed wave symbols and continuous wave symbols; adjusting the sending period of the target sensing frame comprises: shortening the sending period of the target sensing frame when the number of pulsed wave symbols carried by the target sensing frame is reduced; and lengthening the sending period of the target sensing frame when the number of continuous wave symbols carried by the target sensing frame is reduced.

[0070] The adjustment of the sending period of the target sensing frame according to the change in the number of different types of sensing signals carried in the target sensing frame can match the sending period of the target sensing frame with the type and number of the sensing signals carried in the target sensing frame, thereby realizing more accurate sensing.

[0071] For example, in the case that the number of pulse wave symbols carried by the target sensing frame is reduced, it can be determined that the continuous wave symbol needs to be used at present, i.e., the target device close to the base station is sensed, at this time, the transmission period of the target sensing frame can be shortened to facilitate sensing the target device as soon as possible. For example, the transmission period of the target sensing frame is adjusted from 2 ms (milliseconds) to 1 ms. The saved time period can be used to transmit other communication signals to improve the transmission efficiency of the communication signals, or the saved time period can be used for no operation to save energy.

[0072] In the case that the number of continuous wave symbols carried by the target sensing frame is reduced, it can be determined that the pulse wave symbol needs to be used at present, i.e., the target device far away from the base station is sensed, at this time, the transmission period of the target sensing frame can be appropriately extended to facilitate sufficient sensing of the target device far away from the base station to obtain the position information of the target device.

[0073] Compared with the prior art, the transmission period of the target sensing frame is shortened, which not only saves the communication resources, but also maintains the continuous sensing of the target device. The transmission period of the target sensing frame is extended, which can realize sufficient sensing of the target device far away from the base station and improve the sensing accuracy of the target device.

[0074] In some exemplary embodiments, before the step S101 of determining the configuration scheme of the sensing signal according to the sensing result, the method further comprises: determining an initial configuration scheme according to an application scenario in which the target device is located; configuring the sensing signal based on the initial configuration scheme to obtain the target sensing frame; transmitting the target sensing frame to sense the target device and determine the position information of the target device.

[0075] The application scenario in which the target device is located is the current working scenario of the target device. For example, the application scenario includes any one of the following: a low-altitude application scenario, a small-range water application scenario, and a large-range water application scenario.

[0076] In the low-altitude application scenario (e.g., the scenario of sensing small flying devices such as unmanned aerial vehicles), in the downlink direction, the initial configuration scheme can be determined as carrying 4 P wave symbols and 3 C wave symbols in the sensing frame; in the uplink direction, the initial configuration scheme can be determined as carrying 4 P wave symbols and 2 C wave symbols in the sensing frame.

[0077] In a small range of water application scenarios (such as hydrological monitoring in a lake water area), in the downlink direction, the initial configuration scheme can be determined as carrying 4 P-wave symbols and 3 C-wave symbols in the sensing frame; in the uplink direction, the initial configuration scheme can be determined as carrying 4 P-wave symbols and 3 C-wave symbols in the sensing frame.

[0078] In a large range of water application scenarios (such as sensing by devices in a river channel or a sea channel), in the downlink direction, the initial configuration scheme can be determined as carrying 1 P-wave symbol and 3 C-wave symbols in the sensing frame; in the uplink direction, the initial configuration scheme can be determined as carrying 4 P-wave symbols and 3 C-wave symbols in the sensing frame.

[0079] Based on the determination of the initial configuration scheme in different scenarios corresponding to different application scenarios, and then determining the target sensing frame based on the initial configuration scheme, different target sensing frames can be used in different application scenarios to sense the target device, thereby improving the sensing accuracy of the position of the target device.

[0080] In some embodiments, the target device is regarded as a "point" regardless of its volume or shape, and then the sensing ranges of different wireless transmitting devices for sensing the target device can be distinguished based on the scattering cross-sectional area, so as to facilitate subsequent sensing of the target device within the sensing range of the wireless transmitting device, thereby improving the sensing accuracy of the target device.

[0081] For example, the symbols in the sensing signal in the initial configuration scheme include pulse wave symbols; the target sensing frame is used to sense the target device to determine the position information of the target device, including:

[0082] According to the maximum value and the minimum value of the pulse wave symbol, a maximum measurable distance point and a minimum measurable distance point are determined respectively; using the pulse wave symbol carried by the target sensing frame, the devices at the maximum measurable distance point and the minimum measurable distance point are sensed respectively to determine a target sensing area; according to the target sensing area and the reflection power information corresponding to the target sensing frame obtained, the sensing range of the wireless transmitting device is determined.

[0083] The sensing range of the wireless transmitting device is the range for sensing the target device. The sensing range of the wireless transmitting device includes the position information of the target device. The maximum measurable distance point is the farthest distance point that can be sensed according to the maximum value of the pulse wave symbol; the minimum measurable distance point is the nearest distance point that can be sensed according to the minimum value of the pulse wave symbol; the above distance points can be represented by horizontal and vertical values.

[0084] For example, if the value of the horizontal direction corresponding to the maximum measurable distance point is x1, and the value of the vertical direction is y1, then the corresponding maximum perception angle is The maximum perception area is

[0085] If the value of the horizontal direction corresponding to the minimum measurable distance point is x2, and the value of the vertical direction is y2, then the corresponding minimum perception angle is The maximum perception area is

[0086] Further, the perception range of the target perception angle θ is [α, β], and the corresponding value range of the target perception area S is [S1, S2].

[0087] In some embodiments, the reflection power information corresponding to the target perception frame includes: the power of the electromagnetic wave reflected back by the target device, and the power of the signal reflected back by the target device reaching the receiving antenna.

[0088] If the power of the electromagnetic wave emitted by the transmitting antenna of the AAU is P1, the formula is used to represent; the power of the electromagnetic wave reflected back by the target device is P2, the formula is used to represent; and the power of the signal reflected back by the target device reaching the receiving antenna of the AAU is P3, the formula is used to represent.

[0089] Wherein, P t represents the transmission power of the transmitting antenna;

[0090] R represents the target distance between the base station and the target device;

[0091] S represents the scattering cross-sectional area corresponding to the perception of the target device;

[0092] G t represents the gain of the transmitting antenna; λ represents the wavelength of the electromagnetic wave, and Ar represents the effective receiving area of the receiving antenna.

[0093] According to the above three power formulas, the following can be calculated

[0094] As can be seen from the formula of P3, the power P3 of the signal reflected back by the target device reaching the receiving antenna of the AAU is proportional to the scattering cross-sectional area S and inversely proportional to the target distance R.

[0095] Therefore, in the case that the power of the electromagnetic wave emitted by the transmitting antenna of the AAU is the same, the value range of the power reflected back by the corresponding target device is: In other words, the perception range of the wireless sending device is

[0096] The perception range corresponding to the wireless sending device is determined in the manner, so as to narrow the perception range of the target device, accelerate the perception speed of the target device, and improve the perception accuracy of the target device.

[0097] In a second aspect, the embodiments of the present disclosure provide a communication system.

[0098] Figure 4 A constituent block diagram of a communication system provided by the embodiments of the present disclosure is shown in FIG. 4. Figure 4 As shown in the figure, the communication system includes, but is not limited to, the following devices: an operation and maintenance server 410, a core network device 420, a base station 430, an active antenna unit (AAU) 440, a back wave generator 450, and a terminal 460.

[0099] The base station 430 includes a main control board card 431, a perception board card 432, a communication board card 433, an intelligent fusion board card 434, and a baseband processing unit 435.

[0100] The perception board card 432 is configured to send a perception signal to the AAU 440, so that the AAU 440 sends the perception signal and performs perception on a target device. When the perception signal detects the target device and reflects a reflected signal back to the back wave generator 450 from the target device, the back wave generator 450 performs multiple sampling detections on the reflected signal to determine the distance between the target device and the base station 430.

[0101] The communication board card 433 is configured to send / receive a communication signal, which is a signal for information interaction between the base station 430 and the terminal 460.

[0102] The intelligent fusion board card 434 is configured to process the communication signal and the perception signal, so as to realize the perception on the target device and determine the motion trajectory of the target device on the base station side.

[0103] By superimposing the communication signal and the perception signal on the base station side, the communication signal and the perception signal share the radio spectrum resource. In a radio frame, the communication information can be transmitted and the target device can be perceived, the spectrum resource is saved, and the spectrum utilization rate can be improved.

[0104] For example, Figure 5 A structure diagram of a radio frame provided by the embodiments of the present disclosure is shown in FIG. 5. Figure 5 As shown in the figure, the duration corresponding to the radio frame is 10 ms, and the radio frame includes 20 slots, i.e., slot0, slot1, …, slot19.

[0105] Each slot corresponds to 0.5ms, and a slot includes 14 symbols; two slots constitute a radio subframe, and the duration of a radio subframe is 1ms.

[0106] For example, if a cycle consists of 10 time slots, and the sensing signal is transmitted only in the first time slot (D0) and the sixth time slot (D5), while the remaining time slots are used for communication signal transmission; then through Figure 5 When transmitting communication signals and sensing signals in the wireless frame shown, sensing signals can be transmitted in the D0, D5, 11th time slot (D10), and 16th time slot (D15) of the wireless frame.

[0107] Figure 6 This is a flowchart illustrating another target perception method provided in an embodiment of this disclosure. This target perception method can be applied to a base station. For example... Figure 6 As shown, the target perception method includes, but is not limited to, the following steps.

[0108] Step S601: Determine the initial configuration scheme according to the application scenario of the target device, and configure the sensing signal based on the initial configuration scheme to obtain the target sensing frame.

[0109] The application scenarios in which the target equipment is used include any of the following: low-altitude application scenarios, small-scale water application scenarios, and large-scale water application scenarios.

[0110] In low-altitude application scenarios, the initial configuration is as follows: in the downlink direction, the sensing frame carries 4 P-wave symbols and 3 C-wave symbols, and is used as the transmit frame; in the uplink direction, the sensing frame carries 4 P-wave symbols and 2 C-wave symbols, and is used as the receive frame. The carrier bandwidth for low-altitude application scenarios is 100 MHz, each P-wave symbol occupies 1 microsecond (μs), and the sensing range is 500 meters horizontally and 600 meters vertically, facilitating the detection of low-altitude flying targets such as drones.

[0111] In small-scale water area applications (such as hydrological monitoring in lakes), the initial configuration is as follows: in the downlink direction, the sensing frame carries 4 P-wave symbols and 3 C-wave symbols, and is used as the transmit frame; in the uplink direction, the sensing frame carries 4 P-wave symbols and 3 C-wave symbols, and is used as the receive frame. The carrier bandwidth for this small-scale water area application is 50MHz, each P-wave symbol occupies 2μs, and the sensing range is 360 meters to 3.9312 kilometers horizontally, facilitating the sensing of target equipment performing water quality detection (or hydrological monitoring) in small water areas.

[0112] In large-scale water area applications (e.g., sensing devices in river channels or sea lanes), the initial configuration is as follows: in the downlink direction, the sensing frame carries one P-wave symbol and three C-wave symbols, and is used as the transmit frame; in the uplink direction, the sensing frame carries four P-wave symbols and three C-wave symbols, and is used as the receive frame. The carrier bandwidth for this large-scale water area application is 20MHz, each P-wave symbol occupies 8μs, and the sensing range is 720 meters to 19.920 kilometers horizontally, facilitating the sensing of target devices in large water areas.

[0113] Step S602: Send a target perception frame to perceive the target device.

[0114] In the case of transmitting a target sensing frame with a transmission period of T2, if the duration of a wireless frame is T1, then the number of times the corresponding sensing signal is transmitted is N = T1 / T2. T2 is less than or equal to T1.

[0115] For example, if T1 is 10ms and T2 is 2ms, then the sensing signal is sent 5 times. That is, it takes 5 transmissions of the sensing signal to complete a complete wireless frame.

[0116] Step S603: Determine whether the target device was detected in the previous n sensing results.

[0117] Where n is an integer greater than or equal to 1. The sensing result can be judged once at preset intervals. For example, the sensing result can be judged once at a preset interval of T3 (e.g., 0.5ms) to achieve echo detection.

[0118] If the target device is detected at least once in the first n sensing results, proceed to step S604; if the target device is not detected in any of the first n sensing results, proceed to step S605.

[0119] Step S604: Keep the configuration scheme of the sensing signal unchanged.

[0120] If the target device is detected at least once in the first n sensing results, it means that the configuration scheme of the sensing signal carried in the target sensing frame is suitable for the current sensing environment. The configuration scheme can be kept unchanged so that the sensing signal carried in the target sensing frame can continue to be used to sense the target device.

[0121] After completing step S604, return to continue executing step S602.

[0122] Step S605: Adjust the number and / or type of symbols in the sensing signal carried by the target sensing frame.

[0123] The symbols in the sensing signal carried by the target sensing frame include C-wave symbols and P-wave symbols. Different target sensing frames can be obtained depending on the ratio of C-wave symbols to P-wave symbols carried in the target sensing frame.

[0124] In some embodiments, the adjustment of the sensing signal carried by the target sensing frame can be achieved by reducing the number of C-wave symbols carried by the target sensing frame, and / or reducing the number of P-wave symbols carried by the target sensing frame.

[0125] In the above adjustment process, one C-wave symbol (and / or one P-wave symbol) can be reduced each time to obtain an adjusted target sensing frame. The sensing signal carried by the adjusted target sensing frame is then used to sense the target device, so that the adjusted target sensing frame is more suitable for sensing the target device.

[0126] P-wave symbols are suitable for long-range sensing but have a blind spot, while C-wave symbols are suitable for short-range sensing. Adjusting the number of C-wave and / or P-wave symbols can balance the sensing range for both long and short distances.

[0127] Furthermore, when the target device is not detected, the above adjustment scheme is used to adjust the number and / or type of symbols in the sensing signal carried by the target sensing frame, and the sensing signal carried by the adjusted target sensing frame is used to continuously sense the target device. This enables the target device in motion to be sensed at different times, thereby achieving continuous sensing of the target device in different ranges and improving the accuracy of the sensing of the target device.

[0128] In some embodiments, while performing step S605, the transmission period of the target sensing frame can also be adjusted if the configuration scheme of the sensing signal changes.

[0129] The adjustment of the transmission period of the target sensing frame includes: shortening the transmission period of the target sensing frame when the number of pulse wave symbols carried by the target sensing frame decreases; and extending the transmission period of the target sensing frame when the number of continuous wave symbols carried by the target sensing frame decreases.

[0130] In the absence of a target device and by reducing the number of P-wave symbols carried in the target sensing frame, the transmission cycle of the target sensing frame can be shortened so that the C-wave symbols carried in the target sensing frame can play a role in quickly sensing the target device within a short range, thereby accelerating the sensing speed of the target device.

[0131] For example, if a target sensing frame carries 4 P-wave symbols and 3 C-wave symbols, and the target device is not detected using this frame, the number of symbols in the sensing signal can be adjusted to carry 3 P-wave symbols and 3 C-wave symbols to obtain an adjusted target sensing frame. Simultaneously, the transmission cycle of this target sensing frame can be shortened (e.g., changing from sending the target sensing frame once every 2ms to sending it once every 1ms, thus saving time). When using this adjusted target sensing frame for sensing, compared to using the original target sensing frame carrying 4 P-wave symbols and 3 C-wave symbols, both the transmission and reception power are reduced by 25%, achieving energy savings and making the adjusted target sensing frame more suitable for sensing target devices within a short range.

[0132] Similarly, after performing the above adjustments, the number and / or type of symbols of the sensing signal carried in the target sensing frame can be continuously adjusted. For example, a target sensing frame originally carrying m P-wave symbols and m C-wave symbols can be gradually adjusted to a target sensing frame carrying (m-1) P-wave symbols and (m-1) C-wave symbols, until it is changed to a target sensing frame carrying 1 P-wave symbol or 1 C-wave symbol. During the above adjustment process, the transmission power and reception power of the sensing signal are reduced accordingly, achieving energy saving. Here, m is an integer greater than 1.

[0133] In some embodiments, since base stations supporting different protocol versions have different power consumption, if a base station supporting a high protocol version can save 3.5 to 4 kilowatts (kW) of power consumption by using the above method, then multiple base stations supporting high protocol versions will save even more power consumption, thereby saving energy.

[0134] In some embodiments, after shortening the transmission period of the target sensing frame, continuous sensing of the target device can be ensured within the adjusted transmission period of the target sensing frame. At the same time, the time saved can be used to carry communication signals or to save energy.

[0135] In the absence of a target device and with a reduction in the number of C-wave symbols carried in the target sensing frame, extending the transmission period of the target sensing frame enables the P-wave symbols carried in the target sensing frame to function, allowing for long-term sensing of target devices within a long distance range, thus facilitating the detection of target devices located far from the base station.

[0136] For example, if the target sensing frame carries one P-wave symbol and three C-wave symbols, and the target device is not detected when using the target sensing frame, the transmission period of the target sensing frame is adjusted (e.g., the transmission period of the target sensing frame is extended (e.g., from sending the target sensing frame once every 2ms to sending the target sensing frame once every 4ms)), and the target sensing frame is used to continue to sense the target device.

[0137] If the target device is still not detected, the number of symbols of the sensing signal carried in the target sensing frame needs to be adjusted (e.g., adjust the number of symbols of the sensing signal carried in the target sensing frame to carry 2 P-wave symbols and 3 C-wave symbols) to obtain an adjusted target sensing frame. Then, the adjusted target sensing frame is used to sense the target device. Compared with the original target sensing frame carrying 1 P-wave symbol and 3 C-wave symbols, it can sense target devices at a greater distance from the base station, thereby improving the accuracy of target device sensing.

[0138] By using the sensing signals carried in the adjusted target sensing frame to sense the target device, the configuration scheme of the sensing signals carried in the target sensing frame can be dynamically adjusted according to real-time sensing information while continuously carrying out sensing services, so as to meet the sensing needs in different application scenarios.

[0139] After completing step S605, return to continue executing step S602.

[0140] Step S606: If the number of pulse wave symbols and / or the number of continuous wave symbols carried by the target sensing frame is one, and the target device is not sensed by the sensing signal carried by the target sensing frame, the sensing of the target device shall be stopped.

[0141] Since the number of pulse wave symbols and the number of continuous wave symbols carried by the target sensing frame are both one, the corresponding sensing range is fixed. If the target device is still not detected, it means that there is no target device within the sensing range. At this time, the sensing of the target device can be stopped (e.g., closing the signal transmission and reception channel).

[0142] Thirdly, embodiments of this disclosure provide a target sensing device.

[0143] Figure 7 This is a block diagram illustrating the composition of a target sensing device according to an embodiment of the present disclosure. The target sensing device can be installed in a base station.

[0146] The configuration module 702 is used to configure the sensing signal based on the configuration scheme of the sensing signal to obtain the target sensing frame.

[0147] The sending module 703 is used to send target perception frames to perceive the target device and determine the location information of the target device.

[0148] It should be noted that the target perception device in this embodiment can implement any one of the target perception methods in this disclosure.

[0149] According to the target sensing device of this disclosure, by determining the sensing signal carried in the target sensing frame through the sensing result by the determining module, the sensing signal carried in the target sensing frame can be made more suitable for sensing the target device; by using the configuration module to dynamically configure the sensing signal based on the configuration scheme of the sensing signal to obtain the target sensing frame, the power consumption of the target sensing frame can be reduced to achieve the effect of energy saving; and, the target sensing frame is continuously sent by the sending module to facilitate continuous sensing of the target device. Compared with the related technology, which stops the transmission and reception of sensing signals when the target device is sensed, the continuous sensing of the target device can be guaranteed.
