[0023] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] In this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0025] It should be noted that in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] With the rapid development of information technology, sixth-generation mobile communication technology, as the next generation of mobile communication technology, will integrate communication, sensing, and computing capabilities, deeply merging the physical, biological, and digital worlds to provide higher communication speeds, more accurate target perception, and broader connectivity for everything. Integrated Sensing and Communication (ISAC) is a key technology of sixth-generation mobile communication. Higher frequency bands, wider bandwidths, and larger antenna arrays enable high-precision, high-resolution sensing and high-speed, high-reliability communication, gradually realizing the vision of intelligent interconnection of everything across air, land, sea, and the internet.

[0027] Currently, the integrated sensing industry is in the small-scale pilot stage in various scenarios and fields such as low-altitude economy, low-altitude security, waterways, and sea surface detection, while large-scale commercial applications are being deployed. At present, the sensing signal waveforms are mainly pulse waves and continuous waves. Here, pulse wave sensing signals are used to achieve short-range and long-range sensing coverage, while continuous wave sensing signals are used to achieve ultra-short-range sensing coverage. In the current sensing signal configuration, pulse wave sensing signals used in different time slots all have the same pulse width. Under the same pulse width, the sensing coverage distance is the same, which is not flexible enough and will result in coverage blind spots (sensing blind spots). Even if continuous waves are used to supplement coverage, continuous wave sensing signals cannot completely guarantee coverage of the blind spots of the current fixed-pulse-width pulse wave sensing signals, and coverage blind spots will still exist, as shown in Figure 1(a). Moreover, this method occupies multiple time-domain symbol resources, making it difficult to stagger time-frequency resource configuration in multi-station networking scenarios, which can easily cause mutual interference between stations.

[0028] However, with the large-scale commercial deployment of integrated sensing networks underway, a new, flexible, and highly adaptable sensing signal configuration method is urgently needed in various scenarios such as low-altitude economy, low-altitude security, waterways, and sea surface detection to achieve blind-spot-free coverage within the sensing area. Researching such a new, flexible, and highly adaptable sensing signal configuration method is of great significance for the commercial development of integrated sensing.

[0029] In view of this, the present disclosure provides a sensing signal configuration method, which involves determining the configuration information of a sensing area; determining the sensing signal configuration corresponding to the sensing area based on the configuration information of the sensing area; the sensing signal configuration is used to configure the sensing signal for sensing the sensing area; the sensing signal includes at least one pulse wave sensing signal with a pulse width and / or a continuous wave sensing signal.

[0030] In this way, for different sensing areas, at least one pulse wave sensing signal and / or continuous wave sensing signal with a specific pulse width can be configured based on the configuration information of that sensing area to provide sensing coverage, thus improving the flexibility of sensing signal configuration. By rationally utilizing the characteristics and complementary advantages of pulse waves and continuous waves with different pulse widths, the defect of sensing blind spots that may occur when using only pulse wave sensing signals and continuous wave sensing signals with a single pulse width to sense the sensing area is effectively overcome, reducing interference in complex networking scenarios and achieving complete sensing coverage of the sensing area.

[0031] For example, referring to Figure 1(b), a pulse wave sensing signal with at least one pulse width and a continuous wave sensing signal are used to sense the sensing area. This utilizes the characteristics of pulse waves with different pulse widths and their complementary advantages, effectively overcoming the defect of sensing blind spots that may occur when using only a single pulse wave sensing signal and a continuous wave sensing signal to sense the sensing area.

[0032] The network architecture of the sensing network (including but not limited to current mobile sensing networks and future mobile sensing networks (such as 6th generation mobile communication networks, 6G)) in this disclosure embodiment may include network devices (e.g., base stations (sensing base stations, sensing stations), core network devices) and terminal devices. Here, the sensing base station can be used for communication and sensing with the terminal device. The number of sensing base stations and terminal-side backups can be one or more, and this disclosure does not limit this.

[0033] In some embodiments, a sensing base station can sense and communicate with multiple terminal devices, and a terminal device can also be sensed and communicated with by multiple sensing base stations.

[0034] The method provided in this disclosure can be applied to a network scenario of integrated sensing base stations. For example, as shown in Figure 2, it includes at least one sensing base station 10 and at least one drone 20. There are no obstructions between the sensing base station 10 and the drone 20, forming a network coverage area. Based on the movement range of the drone 20, the coverage area and link budget of each sensing base station 10 can be determined, thereby further determining the waveform-related parameters on the transmitting side of the sensing base station 10, forming a continuous coverage network.

[0035] Here, the sensing base station includes a baseband processing unit (gNodeB, GNB) and an active antenna unit (AAU). The core network equipment includes at least a sensing function (SF).

[0036] In some embodiments, the sensing network element can flexibly design the length of sensing symbols with different waveforms to achieve blind-spot-free coverage of the sensing area based on factors such as the coverage distance and link budget of the sensing base station.

[0037] For example, Figure 3 is a schematic diagram of a sensing system according to some embodiments, which includes: SF, GNB, and AAU. Here, the AAU integrates multiple radio frequency transceiver units.

[0038] SF is used to determine the configuration information of the sensing area. Here, the configuration information of the sensing area includes a first distance and a second distance, where the first distance is the maximum sensing coverage distance of the sensing area, and the second distance is the minimum sensing coverage distance of the sensing area. Based on the configuration information of the sensing area, SF can determine the sensing signal configuration corresponding to the sensing area. The sensing signal configuration is used to configure the sensing signals for sensing the sensing area, and the sensing signals include at least one pulse wave sensing signal with a pulse width and / or a continuous wave sensing signal.

[0039] The GNB is used to generate the sequence of sensing beams, including the sensing signals configured in different symbols within the sensing time slot, that is, to generate the transmission sequence of sensing signals.

[0040] An AAU (Agent Active Antenna) is used to transmit sensing signals based on a transmission sequence. The AAU antenna sends the sensing signals into the air, where they are transmitted via electromagnetic waves to the terminal within the sensing area. Upon receiving the sensing signal, the terminal reflects the echo signal. The receiving end (base station) receives the echo signal, demodulates and measures it, and finally outputs the terminal's sensing information, including trajectory and velocity information. In this way, pulse wave sensing signals of at least one pulse width and / or continuous wave sensing signals compensate for each other, achieving continuous, blind-spot-free coverage of the sensing area.

[0041] Here, a continuous wave refers to a transmitted signal whose phase is continuous at the corresponding symbol position. A pulse wave refers to a transmitted signal whose phase is discontinuous at the corresponding symbol position, usually transmitted only for a short period of time, typically 1-8 microseconds.

[0042] The continuous wave sensing signal in this disclosure may have other names, such as continuous wave or continuous wave signal, and this disclosure does not limit it.

[0043] The pulse wave sensing signal has other names, such as pulse wave or pulse wave signal, and this disclosure does not limit it.

[0044] The sensing distance in this disclosure may have other names, such as coverage distance, sensing coverage distance, etc., and this disclosure does not limit it.

[0045] The perception blind spot in this disclosure may have other names, such as coverage blind spot, blind spot, perception coverage blind spot, blind spot range, etc., and this disclosure does not limit it.

[0046] In some embodiments, the base station may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station in a 5th generation mobile communication network (5G), or a base station in a future communication system. The base station may include various macro base stations, micro base stations, femtocell base stations, wireless remote extensions, reconfigurable intelligent surfaces (RISS), routers, wireless fidelity (WIFI) devices, or various network-side devices such as primary cells and secondary cells.

[0047] In some embodiments, the terminal can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can also be deployed in the air (e.g., on drones, airplanes, balloons, and satellites). The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments disclosed herein do not limit the application scenarios. The term "terminal" can sometimes also refer to a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent, or UE device, etc., but this disclosure does not limit the terminology used in this embodiment.

[0048] It should be noted that Figure 2 or Figure 3 is only an exemplary framework diagram. The number of devices or devices included in Figure 2 or Figure 3, and the names of each device are not limited. In addition to the devices shown in Figure 2 or Figure 3, the sensing system may also include other devices.

[0049] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0050] This disclosure provides a sensing signal configuration method, as shown in FIG4, the method comprising the following steps:

[0051] S101. Determine the configuration information of the sensing area.

[0052] In some embodiments, the configuration information of the sensing area includes a first distance and a second distance, where the first distance is the maximum sensing coverage distance of the sensing area, and the second distance is the minimum sensing coverage distance of the sensing area. It is understood that to achieve complete sensing coverage of the sensing area, it is necessary to achieve sensing coverage of at least the area between the first distance and the second distance.

[0053] In some embodiments, the configuration information of the sensing area further includes sensing correlation indicators, which include at least one of the following: false detection rate, false negative rate, and sensing accuracy.

[0054] Here, the false detection rate, also known as the false alarm rate or false alarm probability, refers to the probability of incorrectly identifying noise or other non-target signals as target signals during signal detection. The false detection rate refers to the proportion of target signals that are not correctly identified and detected during signal detection. Perception accuracy is an important indicator for measuring the accuracy of a system in identifying target signals.

[0055] In some embodiments, the configuration information of the sensing area further includes configuration information related to the sensing targets within the sensing area. The configuration information related to the sensing targets may include the minimum received power of the sensing targets. Here, the minimum received power refers to the minimum received power required by the sensing target to meet the requirements of sensing-related performance indicators (e.g., false detection rate, missed detection rate, sensing accuracy, etc.). The minimum received power of the sensing targets is also strongly correlated with the performance of the detection algorithm at the receiver of the sensing signal's echo signal.

[0056] S102. Based on the configuration information of the sensing area, determine the sensing signal configuration corresponding to the sensing area.

[0057] Here, the sensing signal configuration is used to configure a sensing signal for sensing a sensing area, the sensing signal including at least one pulse wave sensing signal and / or a continuous wave sensing signal with a pulse width.

[0058] It is understandable that the maximum sensing distance of a pulse wave sensing signal varies depending on its pulse width. Based on these different maximum sensing distances, various pulse widths of pulse wave sensing signals can be defined. For example, there are short pulse (SP) sensing signals, medium pulse (MP) sensing signals, and long pulse (LP) sensing signals. Different pulse widths of pulse wave sensing signals can be used to detect signals at different maximum sensing distances. The greater the required maximum sensing distance, the wider the pulse width of the pulse wave sensing signal needs to be configured. Pulse wave sensing signals with different pulse widths can also compensate for each other's coverage blind spots, thereby achieving flexible symbol sensing and networking.

[0059] In some embodiments, the maximum sensing distance of the sensing signal is determined based on at least one of the following: the minimum received power of the sensing target within the sensing area, the transmitted power of the sensing signal, the processing gain of the link between the transmitting node of the sensing signal and the sensing target, the path loss between the transmitting node of the sensing signal and the sensing target, and the center frequency.

[0060] In some embodiments, the maximum sensing distance of the continuous wave sensing signal can be calculated and determined based on the minimum received power, transmitted power, and continuous wave link processing gain required for the sensing target within the sensing area to be successfully detected.

[0061] For example, the maximum sensing distance of the continuous wave sensing signal, i.e., D1, can be solved based on the following formulas (1) and (2).

[0062] For example, the continuous wave link budget calculation formula is: RP1=Txpower1+Gain1-Pathloss1 (1)

[0063] Here, RP1 is the minimum received power required for the sensing target to be successfully detected, TxPower1 represents the transmit power of the continuous wave sensing signal, Gain1 represents the processing gain of the continuous wave link, Gain1 can be expressed as a formula related to the number of symbols occupied by the continuous wave sensing signal, the specific expression of the formula is strongly related to the processing algorithm of the receiver, Pathloss1 represents the path loss of the continuous wave link, Pathloss1 can be expressed as a formula related to the sensing distance.

[0064] For example, the formula for calculating continuous wave link attenuation is: Pathloss1=33+20*log10(f0 / c)+40*log10(D1)-10*log10(RCS) (2)

[0065] Here, f0 represents the center frequency of the continuous wave link, c is the speed of light, RCS is the reflection coefficient of the object being sensed, and D1 represents the maximum sensing distance of the continuous wave sensing signal.

[0066] Link budget refers to the sum of all gains and attenuations from the transmitter through the radio frequency medium and reflections through objects to the receiver. It requires modeling and analyzing various influencing factors in the actual system.

[0067] It is understandable that the transmission power of the continuous wave sensing signal and the number of symbols occupied by the continuous wave sensing signal can be pre-configured, and thus the maximum sensing distance of the continuous wave sensing signal can be pre-determined, for example, the number of symbols occupied by the continuous wave sensing signal is 2.

[0068] Understandably, continuous wave sensing signals are suitable for short-range sensing due to their high stability and resolution at close range. For example, in scenarios such as vehicle collision avoidance systems and underground pipeline detection, continuous wave radar can accurately measure the distance and velocity of targets. However, because continuous wave sensing signals are subject to attenuation and interference during propagation, using them for long-range sensing requires higher transmission power and more symbols, leading to resource waste.

[0069] For long-distance sensing requirements, the coverage distance of continuous wave sensing signals may not be sufficient, making pulse wave sensing signals a better choice. Pulse wave sensing signals can sense farther distances and offer higher accuracy and interference resistance. The pulse width TP of the pulse wave sensing signal is related to at least one of the following: the maximum sensing distance L of the pulse wave sensing signal, the link processing gain of the pulse wave, and performance indicators. Here, the longer the pulse width TP of the pulse wave sensing signal, the greater the maximum sensing distance L, but the greater the sensing blind zone distance. For example, the sensing blind zone distance of the pulse wave sensing signal is BP = c * TP / 2, where c is the speed of light. The sensing blind zone of the pulse wave sensing signal needs to be supplemented by another pulse wave sensing signal or continuous wave sensing signal with a different pulse width to achieve continuous coverage without blind zones within the sensing area.

[0070] In some embodiments, the pulse width of the pulse wave sensing signal can be determined based on the following parameters: the processing gain of the link between the transmitting node of the pulse wave sensing signal and the sensing target within the sensing area, the minimum received power of the sensing target within the sensing area, the maximum sensing distance of the pulse wave sensing signal, the transmitting power of the pulse wave sensing signal, the path loss between the transmitting node of the pulse wave sensing signal and the sensing target, and the center frequency.

[0071] For example, the processing gain Gain2 of the pulse wave link can be solved based on the following formulas (3) and (4), and then the pulse width of the pulse wave sensing signal can be obtained according to the formula between Gain2 and the pulse width of the pulse wave sensing signal.

[0072] For example, the pulse wave link budget calculation formula is: Gain2=RP2-(Txpower2-Pathloss2) (3)

[0073] Here, RP2 represents the minimum received power of the sensing target, TxPower2 represents the transmitted power of the pulse wave sensing signal, Gain2 represents the processing gain of the continuous wave link, Gain2 can be expressed as a formula related to the pulse width of the pulse wave sensing signal, and the specific expression of the formula is strongly related to the processing algorithm of the receiving end, Pathloss2 represents the path loss of the pulse wave link, Pathloss2 can be expressed as a formula related to the sensing distance.

[0074] For example, the formula for calculating pulse wave link attenuation is: Pathloss2=33+20*log10(f2 / c)+40*log10(D2)-10*log10(RCS) (4)

[0075] Here, f2 represents the center frequency of the pulse wave link, D2 represents the maximum sensing distance of the pulse wave sensing signal, c is the speed of light, and RCS is the reflection coefficient of the sensing object.

[0076] In some embodiments, the receiving window length RP of the pulse wave sensing signal is determined based on the maximum sensing distance L of the pulse wave sensing signal. For example, the receiving window length RP of the pulse wave sensing signal is 2L / c, where c is the speed of light.

[0077] For example, this disclosure provides a schematic diagram of a sensing signal configuration process, as shown in Figure 5. The method includes the following steps:

[0078] S201. Determine the configuration information of the sensing area, which includes a first distance and a second distance. Here, the first distance is the maximum sensing coverage distance of the sensing area, and the second distance is the minimum sensing coverage distance of the sensing area.

[0079] S202. Determine the continuous wave link budget and the pulse wave sensing link budget.

[0080] S203. Determine the maximum sensing distance of the continuous wave sensing signal based on the continuous wave link budget.

[0081] S204. Determine if the maximum sensing distance of the continuous wave sensing signal is greater than the first distance. If the maximum sensing distance of the continuous wave sensing signal is greater than the first distance, determine that the sensing signal used to sense the sensing area includes the continuous wave sensing signal, and end the sensing signal configuration process. This means that allocating only the continuous wave sensing signal is sufficient to meet the coverage requirements, and there is no need to use the pulse wave sensing signal for further coverage. Otherwise, it means that the continuous wave sensing signal alone cannot provide complete sensing coverage of the sensing area, and it is necessary to allocate the pulse wave sensing signal to achieve sensing coverage of the sensing area, and continue to execute S205.

[0082] S205. Based on the minimum received power required for the target to be successfully detected, and using the pulse wave link budget calculation method, the first distance is taken as the current maximum required sensing distance. The pulse wave sensing signal corresponding to the minimum pulse width required to cover the current maximum required sensing distance is determined. The sensing blind zone distance corresponding to the pulse wave sensing signal is calculated, and then the pulse wave sensing signal is added to the sensing signal set.

[0083] S206. Determine whether the blind zone distance of the pulse wave sensing signal is less than the second distance. If the blind zone distance of the pulse wave sensing signal is less than the second distance, determine that at least one pulse wave sensing signal with a pulse width in the currently obtained sensing signal set is the sensing signal for sensing the sensing area, and end the sensing signal configuration process. Otherwise, execute S207.

[0084] S207. Determine whether the sensing blind zone distance of the pulse wave sensing signal is less than the maximum sensing distance of the continuous wave sensing signal; if it is less, proceed to S208. Otherwise, take the sensing blind zone distance of the pulse wave sensing signal as the current maximum required sensing distance, and return to S205 to proceed with the next round of sensing signal allocation.

[0085] S208. Determine at least one pulse wave sensing signal and a continuous wave sensing signal with a pulse width in the currently obtained set of sensing signals as sensing signals for the sensing area, and end the sensing signal configuration process.

[0086] Other details and specific descriptions related to steps S201 to S208 can be found in the descriptions in the above embodiments or examples, and will not be repeated here.

[0087] In some embodiments, the sensing signal for sensing the sensing area includes only a pulse wave sensing signal with at least one pulse width; or, the sensing signal for sensing the sensing area includes only a continuous wave sensing signal; or, the sensing signal for sensing the sensing area includes both a pulse wave sensing signal with at least one pulse width and a continuous wave sensing signal.

[0088] In some embodiments, when the maximum sensing distance of the continuous wave sensing signal is greater than the first distance, the sensing signal for sensing the sensing area includes the continuous wave sensing signal; when the maximum sensing distance of the continuous wave sensing signal is less than or equal to the first distance, the sensing signal for sensing the sensing area includes at least one pulse wave sensing signal with a pulse width.

[0089] In some embodiments, when the maximum sensing distance of the continuous wave sensing signal is less than or equal to the first distance, the sensing signal used to sense the sensing area includes only a pulse wave sensing signal with a pulse width, the maximum sensing distance of the pulse wave sensing signal is greater than or equal to the first distance, and the sensing blind zone distance of the pulse wave sensing signal is less than the second distance.

[0090] In some embodiments, when the maximum sensing distance of the continuous wave sensing signal is less than or equal to a first distance, the sensing signal for sensing the sensing area includes a pulse wave sensing signal with a pulse width and a continuous wave sensing signal. The maximum sensing distance of the pulse wave sensing signal is greater than or equal to the first distance, and the sensing blind zone distance of the pulse wave sensing signal is greater than or equal to a second distance and less than the maximum sensing distance of the continuous wave sensing signal.

[0091] In some embodiments, when the maximum sensing distance of the continuous wave sensing signal is less than or equal to a first distance, the sensing signal for sensing the sensing area includes N pulse wave sensing signals with different pulse widths, where N is a positive integer greater than or equal to 1; among the N pulse wave sensing signals, the maximum sensing distance of the first pulse wave sensing signal is greater than or equal to the first distance; the maximum sensing distance of the i-th pulse wave sensing signal is greater than or equal to the sensing blind zone distance of the (i-1)-th pulse wave sensing signal, where i is a positive integer less than or equal to N.

[0092] In some embodiments, if the blind zone distance of the Nth pulse wave sensing signal among the N pulse wave sensing signals is less than the second distance, it is determined that the sensing signals used to sense the sensing area include only the N pulse wave sensing signals.

[0093] In some embodiments, if the blind zone distance of the Nth pulse wave sensing signal among the N pulse wave sensing signals is greater than or equal to the second distance and less than the maximum sensing distance of the continuous wave sensing signal, the sensing signal for determining the sensing area to be sensed also includes the continuous wave sensing signal.

[0094] In some embodiments, the sensing signal configuration corresponding to the sensing region further includes at least one of the following: the symbol position and / or the number of symbols occupied by the sensing signal (including continuous wave sensing signal and / or pulse wave sensing signal with at least one pulse width) in the sensing time slot, the number of sensing time slots, the starting position of the sensing time slot, the time interval between adjacent sensing signals, and the reception time window of the sensing signal.

[0095] In some embodiments, the sensing signal configuration corresponding to the sending sensing region is sent. For example, the sensing network element sends the sensing signal configuration to at least one base station that senses the sensing region. The at least one base station performs sending and receiving processing of the sensing signal according to the sensing signal configuration.

[0096] In some embodiments, the same network device that senses the sensing region transmits the sensing signal in a time division manner. In this way, the problem of signal interference during the transmission of the sensing signal by the same network device is avoided.

[0097] Exemplarily, as shown in FIG. 6, the sensing time slot includes 14 symbols. The 14 symbols of the sensing time slot are configured into a combination of different continuous wave symbols (i.e., the symbols occupied by the continuous wave sensing signal), short pulse symbols (i.e., the symbols occupied by the pulse wave sensing signal with a short pulse width), medium pulse symbols (i.e., the symbols occupied by the pulse wave sensing signal with a medium pulse width), and long pulse symbols (i.e., the symbols occupied by the pulse wave sensing signal with a long pulse width) according to the actual system requirements. FIG. 6 shows that the sensing time slot is configured with one long pulse symbol (i.e., LP in the figure), placed at symbol 5 (the symbol index starts counting from 0), with a coverage distance of d, where d3 < d < d4; one short pulse symbol (i.e., SP in the figure), placed at symbol 0, with a coverage distance of d, where d1 < d < d2; and two continuous wave symbols (i.e., C in the figure), placed at symbol 11 and symbol 12 respectively, with a coverage distance of d, where d5 < d < d6. The continuous wave sensing signal can be sent or received in a frequency division or comb division or code division错开方式 (the specific meaning of "错开方式" needs to be further determined according to the context, and it may be a misaligned or staggered manner). The transmission window timing represents the corresponding transmission time window of the pulse wave sensing signal and the continuous wave sensing signal, and the reception window timing represents the corresponding reception time window of the pulse wave sensing signal and the continuous wave sensing signal. In FIG. 6, the transmission and reception of the continuous wave sensing signal are simultaneous, while the transmission and reception of the pulse wave sensing signal are not simultaneous.

[0098] For example, the maximum sensing distance of a sensing cell is 2000 meters, the receiving window length is 13.3 μs, and the minimum sensing distance is 600 meters. To meet the performance requirements of continuous wave sensing signals, such as false detection and missed detection, the minimum received power required for the sensing target within the sensing cell is -71 dBm. The corresponding received power of the continuous wave sensing signal is: 28 + 24.5 - 32 - 28 * log10(4.9) - 28 * log10(3000) = -96 dBm. In this case, using only the continuous wave sensing signal is insufficient to meet the sensing requirements; that is, the continuous wave sensing signal cannot cover 2000 meters, but only 400 meters. Therefore, pulse wave sensing signals are needed to address the coverage issue between 400 and 2000 meters. A pulse wave sensing signal with a pulse width of 4µs was designed, with a blind zone distance of 600 meters. Since this blind zone distance is greater than the maximum sensing distance of 400 meters for continuous waves, pulse wave sensing signals with a pulse width less than 4µs need to be allocated. Therefore, a pulse wave sensing signal with a pulse width of 1µs was allocated, with a blind zone distance of 150 meters, which is less than the maximum sensing distance of 400 meters for continuous waves. The allocation is then complete. In other words, the sensing signals allocated to the sensing cell include pulse wave sensing signals with a pulse width of 4µs, pulse wave sensing signals with a pulse width of 1µs, and continuous wave sensing signals. The specific numerical calculation methods in this example can be found in the descriptions of the above embodiments or examples, and will not be repeated here.

[0099] In some embodiments, different network devices sensing a sensing area transmit sensing signals using time-division and / or frequency-division multiplexing. Compared to traditional sensing signals where different time slots use the same pulse width, resulting in the same coverage distance and occupying multiple time-domain symbol resources, this method is less effective in multi-site networking scenarios due to difficulties in staggering time-frequency resource configurations and potential inter-site interference. This disclosure allows different stations sensing a sensing area to transmit sensing signals based on sensing signal configuration using time-division and / or frequency-division multiplexing. The sensing signals include at least one pulse wave sensing signal and a continuous wave sensing signal with different pulse widths, and the transmission resources for these sensing signals are staggered, effectively reducing inter-signal interference.

[0100] For example, referring to Figure 7, a schematic diagram of two sensing stations forming a network for coverage, the number of pulse waves and pulse widths to be covered by sensing station 1 and sensing station 2 are determined by applying the methods in the above embodiments or examples. One sensing time slot includes 14 symbols. To reduce interference, sensing stations 1 and 2 respectively use receiving window timing 1 and receiving window timing 2 to transmit sensing signals. The short-pulse-width pulse wave sensing signal SP0 and the medium-pulse-width pulse wave sensing signal MP0 transmitted by sensing station 1 are time-division multiplexed with the short-pulse-width pulse wave sensing signal SP1 and the medium-pulse-width pulse wave sensing signal MP1 transmitted by sensing station 2. The long-pulse-width pulse wave sensing signal LP0 transmitted by sensing station 1 and the long-pulse-width pulse wave sensing signal LP1 transmitted by sensing station 2 are frequency-division multiplexed with the same method. The continuous wave sensing signals C0 and C1 transmitted by sensing station 1 and the continuous wave sensing signals C0 and C1 transmitted by sensing station 2 are frequency-division multiplexed with the same method. Therefore, the sensing signals transmitted by sensing station 1 and sensing station 2 are completely separate, so there is no interference between the two stations. Moreover, the sensing signal configuration on which sensing station 1 transmits sensing signals and the sensing signal configuration on which sensing station 2 transmits sensing signals can be flexibly adjusted according to the networking situation, which can reduce interference and flexibly form a network, avoid interference between sensing stations, and solve the problem of window over-coverage caused by excessively dense pulse waves.

[0101] Based on this, for different sensing areas, at least one pulse wave sensing signal and / or continuous wave sensing signal with a specific pulse width is configured to cover the sensing area based on the configuration information of that sensing area, thereby improving the flexibility of sensing signal configuration. By rationally utilizing the characteristics and complementary advantages of pulse waves and continuous waves with different pulse widths, the defect of sensing blind spots that may occur when using only pulse wave sensing signals and continuous wave sensing signals with a single pulse width to sense the sensing area is effectively overcome, achieving complete sensing coverage of the sensing area.
