The entire contents of the application are incorporated by reference into this application. Technical Field

[0003] The embodiments of the present application relate to the technical field of integrated communication and perception, and in particular to a configuration method and system for perception signals. Background Art

[0004] Synaesthesia integrates communication and perception, enabling the system to possess both communication and perception capabilities. However, due to differences in their implementation mechanisms and application scenarios, the integration of communication and perception often results in different communication and perception coverage. Communication involves signal transmission between base stations and terminals, so signals only experience one-way link transmission losses when traveling between the base station and the terminal.

[0005] The perception process is achieved by receiving the echo signal from the object after the base station transmits the signal. During this process, the signal not only experiences transmission loss in both directions, but also suffers significant energy loss when the signal reflects off the target surface. This reduces the perception coverage of the perception signal, and sometimes even leads to areas that are not covered. Therefore, the range that the perception signal needs to cover is complex and variable, but the synaesthesia system in related technologies cannot flexibly meet the requirements of different perception coverage areas.

[0021] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0022] FIG1 shows a flow chart of a method for configuring a sensing signal provided by an exemplary embodiment of the present application. Referring to FIG1 , the method includes the following steps.

[0023] Step 102: Calculate the target distance that can be perceived using the target perception signal according to the parameters of the base station.

[0024] The target perception signal includes a continuous wave perception signal or a pulse perception signal; the target distance may include a first distance perceivable using the continuous wave perception signal and a second distance perceivable using the pulse perception signal.

[0025] Among them, the base station can be a single-station telepathic base station, and the parameters of the base station include the carrier wavelength of the base station, the maximum transmit power that the base station can provide when sending continuous wave perception signals, the transmit antenna gain, the receive antenna gain, the isolation between the transmit and receive antennas, the saturation power of the receive antenna, the minimum radar cross section (RCS) of the perceived target, and the minimum detectable power of the continuous wave perception signal.

[0026] The first distance that the continuous wave sensing signal can be perceived can be calculated by: first, according to the saturation power S of the receiving antenna r The isolation I between the transmitting and receiving antennas is used to calculate the maximum transmit power S of the transmitting antenna under the premise that the receiving antenna is not saturated. max，c =S r +I. Then, select P max，c and S max，c The smaller value of c , that is, P c =min(S max，c , P max，c ). After determining the actual maximum transmission power P cThen, according to the carrier wavelength λ, the transmitting antenna gain G t，c , receiving antenna gain G r，c , the minimum RCS value of the perceived target σ and the minimum detectable power of the perceived signal S min，c Calculate the first distance that the continuous wave sensing signal can be perceived

[0027] Step 104: Determine the target perception distance range according to the target perception scene.

[0028] Step 106: Determine a target perception signal configured for the base station according to a magnitude relationship between the target distance and a boundary value of the target perception distance range.

[0029] In the embodiment of the present application, due to the limitation of antenna isolation, continuous wave sensing signals can only be sent with a smaller power, and the sensing signal will have bidirectional transmission loss and reflection loss, so that the sensing distance can only be limited to a smaller range. By introducing pulse sensing signals, the pulse sensing signal adopts a time-sharing transmission and reception method for sensing. All antennas first send the pulse sensing signal. After the transmission is completed, all antennas switch to the receiving state to receive the echo. In this process, there is no need to consider the problem of antenna saturation and a larger power can be used for transmission, thereby covering a longer distance. However, this also causes the pulse sensing signal to have a certain blind spot at the near point. Therefore, the target distance that can be perceived by using the target perception signal is calculated according to the parameters of the base station, wherein the target perception signal includes a continuous wave perception signal or a pulse perception signal; the target perception distance range is determined according to the target perception scenario; based on the target distance and target perception distance range obtained above, according to the size relationship between the target distance and the boundary value of the target perception distance range, it is determined to configure the target perception signal for the base station, so that based on the different characteristics of the continuous wave perception signal and the pulse perception signal in the perception distance range, and the size relationship between the target distance and the boundary value of the target perception distance range, the base station can be flexibly configured with a target perception signal that can meet the perception signal coverage requirements, thereby solving the problem of incomplete perception coverage distance when using only continuous wave perception signals or only pulse perception signals in some cases.

[0030] In one implementation, the boundary values ​​of the target perception distance range include the minimum target perception distance d min and the maximum target perception distance d max , the minimum target perception distance is the target perception distance with the smallest value in the target perception distance range, and the maximum target perception distance is the target perception distance with the largest value in the target perception distance range; then the above-mentioned step 106 may include: when the maximum target perception distance does not exceed the first distance, determining to configure the continuous wave perception signal for the base station.

[0031] In an embodiment of the present application, when the target perception distance range to be perceived is close to the base station and the maximum target perception distance does not exceed the first distance that can be perceived using the continuous wave perception signal, that is, the first distance that can be perceived using the continuous wave perception signal can meet the target perception distance range, so only the continuous wave perception signal is configured for the base station, which meets the target perception distance range while reducing the resource overhead of the perception signal.

[0032] In one implementation, when the maximum target perception distance exceeds the first distance and the minimum target perception distance exceeds the first distance, it is determined to configure the pulse perception signal for the base station.

[0033] In the embodiment of the present application, when the target perception distance range to be perceived is far from the base station, the maximum target perception distance exceeds the first distance perceivable by the continuous wave perception signal, and the minimum target perception distance also exceeds the first distance perceivable by the continuous wave perception signal, that is, the first distance perceivable by the pulse perception signal can meet the target perception distance range, so only the base station is configured with a transmission power of P max，p , the pulse width is The pulse perception signal meets the target perception distance range while reducing the resource overhead of the perception signal.

[0034] In one implementation, when the maximum target perception distance exceeds the first distance and the minimum target perception distance does not exceed the first distance, the pulse width allowed by the pulse perception signal is calculated based on the blind spot range, wherein the blind spot range is zero to the minimum target perception distance; and the second distance that can be perceived using the pulse perception signal is calculated based on the pulse width and the parameters of the base station.

[0035] In the embodiment of the present application, when the first distance perceivable by only the continuous wave sensing signal cannot cover the longer target sensing distance range, and the second distance perceivable by only the pulse sensing signal has a blind spot, and the use of the two sensing signals alone cannot meet the target sensing distance range requirements, it is considered to configure the base station with both the continuous wave sensing signal and the pulse sensing signal. That is, when the maximum target sensing distance exceeds the first distance perceivable by the continuous wave sensing signal and the minimum target sensing distance does not exceed the first distance, the pulse width allowed by the pulse sensing signal is first calculated based on the determined blind spot range of the pulse sensing signal. Then, based on the pulse width and the base station parameters, the symbol length T and the transmitting antenna gain G are sensed. t，p , receiving antenna gain G r，p , the minimum RCS value of the perceived target σ, the minimum detectable power of the pulse perception signal S min，p, calculate the second distance that can be perceived by using the pulse sensing signal alone when the pulse width is t

[0036] Further, after calculating the second distance at which the pulse perception signal can be perceived, determining the target perception signal configured for the base station based on the size relationship between the target distance and the boundary value of the target perception distance range may include: determining the pulse perception signal, or the continuous wave perception signal and the pulse perception signal, to be configured for the base station based on the size relationship between the second distance and the boundary value of the target perception distance range.

[0037] Among them, after making a preliminary judgment based on the first distance that can be perceived using a continuous wave perception signal, another judgment is made based on the second distance that can be perceived using a pulse perception signal, so that according to the size relationship between the first distance, the second distance and the boundary value of the target perception distance range, it is possible to accurately determine the perception signal configured for the base station that can meet the requirements of the target perception distance range.

[0038] In one implementation, determining to configure a target perception signal for the base station based on a magnitude relationship between the second distance and a boundary value of the target perception distance range may include the following steps.

[0039] (1) When the maximum target perception distance does not exceed the second distance, determine to configure the pulse perception signal for the base station.

[0040] In this case, the pulse sensing signal can meet the requirements of the target sensing distance range, so the base station is configured with a transmission power of P max，p , the pulse width is Pulse sensing signal.

[0041] (2) When the maximum target perception distance exceeds the second distance, determine to configure the continuous wave perception signal and the pulse perception signal for the base station.

[0042] In this case, the pulse sensing signal cannot meet the requirements of the target sensing distance range, and it is necessary to configure a continuous wave sensing signal to cover the blind area of ​​the pulse sensing signal. Therefore, the base station is configured with a transmission power of P c The continuous wave sensing signal and the transmission power are P max，p , the pulse width is Pulse sensing signal.

[0043] In one implementation, before the above-mentioned step 102 calculates the target distance that can be perceived using the target perception signal based on the parameters of the base station, the above-mentioned perception signal configuration method may also include: when the base station only supports the use of the continuous wave perception signal, upgrading the base station, wherein the upgraded base station supports the use of the continuous wave perception signal and the pulse perception signal.

[0044] Optionally, when the base station supports the use of continuous wave perception signals and also supports the use of pulse perception signals, the above-mentioned perception signal configuration method can be directly executed to configure the perception signal.

[0045] FIG2 shows a flow chart of another method for configuring a sensing signal provided by an exemplary embodiment of the present application. Referring to FIG2 , the method includes the following steps.

[0046] Step 201: Calculate the first distance L that can be perceived using a continuous wave sensing signal based on the parameters of the base station. c .

[0047] Specifically, the maximum transmission power P that the base station can provide when sending continuous waves is based on the carrier wavelength λ of the base station. max，c , transmit antenna gain G t，c , receiving antenna gain G r，c , the isolation between the transmitting and receiving antennas I, the saturation power of the receiving antenna S r , the minimum RCS value of the perceived target σ, the minimum detectable power of the continuous wave perception signal S min，c , calculate the first distance that the continuous wave sensing signal can perceive

[0048] Step 202: Determine the distance range to be sensed according to the requirements of the sensing scene. min ,d max ].

[0049] Among them, d min Indicates the minimum distance required for perception, d max Indicates the maximum distance that needs to be sensed.

[0050] Step 203, determine d max ≤L c Compare d max With L c The size between, if d max ≤L c Then only configure the base station to have a transmission power of P c If the continuous wave sensing signal is received, the sensing signal configuration process ends; otherwise, step 204 is executed.

[0051] Step 204, determine dmin ≤L c Compare d min With L c The size between, if d min ≤L c , then execute step 205; otherwise, only configure the base station to have a transmission power of P max，p , the pulse width is The pulse sensing signal is sent, and the sensing signal configuration process ends. Where c represents the speed of light, τ represents the antenna transmit and receive state switching delay, P max，p Indicates the maximum transmit power that the base station can provide when sending pulses.

[0052] Step 205: According to the blind area range [0, d min ), calculate the maximum pulse width t allowed by the pulse perception signal, and calculate the second distance L that the pulse perception signal can perceive p First, according to the blind area range [0, d min ) Calculate the maximum pulse width allowed by the pulse sensing signal On this basis, according to the perceived symbol length T, the transmitting antenna gain G t，p , receiving antenna gain G r，p , the minimum RCS value of the perceived target σ, the minimum detectable power of the pulse perception signal S min，p , calculate the second distance that can be perceived by the pulse signal alone when the pulse width is t

[0053] Step 206, determine d max ≤L p Compare d max With L p The size between, if d max ≤L p , then only configure the base station to have a transmission power of P max，p , the pulse width is Otherwise, the base station is configured to simultaneously send two types of perception signals, continuous wave and pulse, in which the transmission power of the continuous wave perception signal is P c , the transmission power of the pulse sensing signal is P max，p , the pulse width is

[0054] In the embodiment of the present application, the first distance L that can be perceived by using the continuous wave sensing signal is first calculated by the parameters of the base station. c , the distance range to be perceived is determined according to the requirements of the perception scene [d min ,d max ]After that, compare d max With L c The size between, if dmax ≤L c At this time, only continuous wave sensing signals can meet the required sensing distance range, so only the base station is configured with a transmission power of P c Continuous wave sensing signal; if d max >L c , then further comparison d is needed min With L c The size between, if d min >L c , then only the pulse sensing signal can meet the required sensing distance range, and only the base station is configured with a transmission power of P max，p , the pulse width is The pulse perception signal; if d min ≤L c , then there is a blind spot in the pulse sensing signal. The maximum pulse width t allowed by the pulse sensing signal can be calculated according to the blind spot range [0, dmin), as well as the second distance L that the pulse sensing signal can perceive. p , and then compare d max With L p The size between, if d max ≤L p , then only configure the base station to have a transmission power of P max，p , the pulse width is The pulse perception signal; if d max >L p , then the base station is configured with a transmission power of P c The continuous wave sensing signal and the transmission power are P max，p , the pulse width is When using only a continuous wave sensing signal or a pulse sensing signal to meet the sensing coverage requirements, only the continuous wave sensing signal or the pulse sensing signal is configured for the base station to reduce resource usage. If using only a continuous wave or pulse signal to meet the sensing coverage requirements, the base station is configured with both a continuous wave sensing signal and a pulse sensing signal to meet the sensing coverage requirements. This allows the base station to flexibly configure the target sensing signal that meets the sensing signal coverage requirements.

[0055] FIG3a, FIG3b, FIG3c, and FIG3d respectively show schematic diagrams of configuration of sensing signals in different scenarios provided by an exemplary embodiment of the present application.

[0056] Referring to Figure 3a, in this scenario, the target perception distance range is close to the base station. For example, when a user enters the area near the base station, the maximum value of the target perception distance range is smaller than the maximum coverage range of the continuous wave perception signal. Therefore, only the continuous wave perception signal is configured for the base station.

[0057] Refer to Figure 3b. In this scenario, the target perception distance range is at the middle point. For example, there is a certain distance between the vehicle and the base station. The pulse perception signal designed according to the minimum value of the target perception distance range can meet the requirements of the target perception distance range. Therefore, only the pulse perception signal is configured for the base station.

[0058] Referring to Figure 3c, in this scenario, the target perception distance range includes three areas: far, medium and near. For example, a communication cell, the pulse perception signal designed according to the minimum value of the target perception distance range cannot meet the requirements of the target perception distance range. Therefore, the base station is configured with both continuous wave perception signals and pulse perception signals.

[0059] As shown in Figure 3d, in this scenario, the target perception distance range is far away from the base station, such as a drone intrusion. The minimum value of the target perception distance range also exceeds the coverage range of the continuous wave perception signal. The continuous wave perception signal cannot provide assistance, so only the pulse perception signal is configured for the base station.

[0060] The present application also provides an exemplary embodiment, in which the base station parameters are: the carrier wavelength λ of the base station is 0.06m, the maximum transmission power P that the base station can provide when sending continuous waves max，c =50dBm, transmitting antenna gain G t，c =15dB, receiving antenna gain G r，c =15dB, the isolation between the transmitting and receiving antennas is I = 65dB, and the saturation power of the receiving antenna is S r =-45dB, the minimum RCS value of the perceived target σ = 1, the minimum detectable power of the continuous wave perception signal S min，c =-90dBm, antenna transmit / receive state switching delay τ = 80ns, according to the perceived symbol length T = 33us, the maximum transmit power P that the base station can provide when sending a pulse max，p =53dBm, transmitting antenna gain G t，p =18dB, receiving antenna gain G r，p =18dB, the minimum detectable power of the pulse sensing signal S min，p =-90dBm. The target sensing distance range required for the target sensing scenario is set to 30m-300m. For this scenario, the configuration method for sensing signals may include the following steps.

[0061] Step 1: Calculate the maximum distance L that can be sensed using continuous wave sensing signals based on the base station parameters. c .

[0062] First, calculate the maximum transmit power S of the transmitting antenna under the premise that the receiving antenna is not saturated. max，c =S r +I=20dBm.

[0063] Then, select Pmax，c and S max，c The smaller value of the two is used as the actual maximum transmission power when sending continuous wave sensing signals, that is, P c =min(S max，c , P max，c )=min(20dBm, 50dBm)=20dBm.

[0064] After determining the actual maximum transmit power P c Then, according to the carrier wavelength λ, the transmitting antenna gain G t，c , receiving antenna gain G r，c , the minimum RCS value of the perceived target σ and the minimum detectable power of the perceived signal S min，c , calculate the maximum distance that the continuous wave sensing signal can perceive

[0065] Step 2: According to the requirements of the target perception scenario, determine the target perception distance range as [30m, 300m].

[0066] Step 3, compare d max With L c Comparing the sizes, we found that d max =300m>L c =116.06m, indicating that only continuous wave sensing signals cannot cover the target sensing scene area, so continue to step 4.

[0067] Step 4, compare d min With L c Comparing the sizes, we found that d min =30m <L c =116.06m, so proceed to step 5.

[0068] Step 5: According to the blind area range [0, d min ), calculate the maximum pulse width allowed by the sensing pulse Further calculation of the maximum distance that can be covered by the pulse signal alone when the pulse width is 120ns

[0069] Step 6, compare d max With L p Comparing the sizes, we found that d max =300m>L p =269.05m, so the base station is configured with continuous wave sensing signals and pulse sensing signals that are sent in time division, where the transmission power of the continuous wave sensing signal is P c =20dBm, the transmission power of the pulse sensing signal is P max，p =53dBm, pulse width is configured as At this pulse width, the maximum range that the pulse sensing signal can cover is At this point, the continuous wave sensing signal can cover the range of [0m, 116.06m], and the pulse sensing signal can cover the range of [116.06m, 417.19m]. The combination of the two can fully meet the coverage requirements of 30m-300m from the base station.
