[0225] In some embodiments, for example, direct measurements can be performed based on wireless signals transmitted by a sensing target to obtain information such as the time delay, angle, and Doppler frequency of multipath components, thereby determining the location and other parameters of the sensing target. However, the sensing target can cause changes in the environmental multipath components, such as due to the presence or movement of the sensing target, resulting in poor accuracy in determining the sensing target information.
[0226] Figure 2 is a schematic diagram illustrating an example of a perception target influencing an environment, provided by an embodiment of the present disclosure. TX1 represents a transmitter, RX represents a receiver, E, E1, E2, E3, and E4 represent environmental targets, and T1, T2, T3, and T4 represent perception targets. The mutual influence between perception targets and environmental targets may include one or more of the following:
[0227] (1) The presence or movement of a sensing target can block or weaken the wireless signal from a transmitter to an environmental target, causing the target to become invisible or the signal to become weaker at the receiver. For example, in Figure 2, the wireless signal from transmitter TX to environmental target E1 is blocked by sensing target T1.
[0228] (2) The presence and movement of sensing targets may block or weaken the wireless signal reflected from an environmental target to the receiver, causing the environmental target to be invisible at the receiver or the signal to be weak. For example, the wireless signal from environmental target E2 to receiver RX in Figure 2 is blocked by sensing target T1.
[0229] (3) Due to the presence or movement of a sensing target, an environmental target may block or weaken the wireless signal from the transmitter to the sensing target, causing the sensing target to be invisible at the receiver or the signal to be weak. For example, in Figure 2, the wireless signal from transmitter TX to sensing target T2 is blocked by environmental target E3.
[0230] (4) Due to the presence and movement of a sensing target, an environmental target may block or weaken the wireless signal reflected from the sensing target to the receiver, causing the sensing target to be invisible at the receiver or the signal to be weakened. For example, the wireless signal reflected from sensing target T3 to receiver RX in Figure 2 is blocked by environmental target E4.
[0231] (5) The appearance and movement of the sensing target may block or weaken the wireless signal from the transmitter to the receiver, that is, the receiver finds that the transmitter's direct path (LOS) is invisible or the signal is weakened. For example, the direct path of the wireless signal from transmitter TX to receiver RX in Figure 2 is blocked by sensing target T4. In fact, this situation also affects the wireless signal reflected by the sensing target at the receiver. Because the transmitter's wireless signal is blocked or weakened by the sensing target, the signal reflected from the sensing target to the receiver also disappears or weakens accordingly, that is, the sensing target becomes invisible or the signal is weakened at the receiver.
[0232] (6) As the sensing target moves, the wireless signal reflected from the sensing target to the receiver changes. For example, its multipath component at the previous moment disappears or weakens, and a new multipath component is generated. For example, when sensing target T1 moves to position T1', the original reflected multipath component disappears, and a new reflected multipath component is generated.
[0233] (7) Due to the presence and movement of sensing targets, some of the wireless signals reflected by the sensing targets may reach certain environmental targets, causing the wireless signal reflected from the environmental targets to become stronger. Here, because the path from the transmitter to the sensing target to the environmental target is not a direct path, that is, its delay is greater than the direct path from the transmitter to the environmental target, the receiver can discern the increased wireless signal from the delay characteristics.
[0234] (8) The wireless signal of the environmental target E at the receiver RX is not affected by the sensing target
[0235] (9) The wireless signal of the sensing target T1 at the receiver RX is not affected by the environmental targets.
[0236] The following describes in detail a method, apparatus, device, and storage medium for determining perception target parameters provided by an embodiment of the present disclosure with reference to the accompanying drawings.

[0270] For example, in one embodiment of the present disclosure, the parameter determination subject of the perception target of the embodiment of the present disclosure can be, for example, a first receiving terminal, and the first receiving terminal can, for example, receive measurement information sent by the remaining receiving terminals. The measurement information can, for example, include at least one of a first multipath component, a second multipath component, a first measurement timestamp corresponding to the current wireless channel, and a second measurement timestamp corresponding to the reference wireless channel.
[0271] For example, in one embodiment of the present disclosure, when a target is detected to appear or move, the first receiving terminal detects change information of a multipath component of a wireless signal received by the first receiving terminal.
[0272] For example, in one embodiment of the present disclosure, the change information of the multipath component includes at least one of the following:
[0273] Directly receive the multipath component reflected by the corresponding sensing target of the current wireless channel;
[0274] Other changing multipath components except the multipath components directly received from the current wireless channel and reflected by the corresponding perceived target.
[0275] For example, in one embodiment of the present disclosure, the multipath component change information includes a multipath component directly received from a corresponding sensing target on the current wireless channel. For example, the multipath component may be a multipath component from transmitter TX1 to receiver RX via sensing target T1 in FIG2 .
[0276] For example, in one embodiment of the present disclosure, the change information of the multipath component includes change information of the multipath component of the environmental target at the first receiving terminal caused by the appearance or movement of the perceived target.
[0277] For example, in one embodiment of the present disclosure, the change information of the multipath component includes change information of the multipath component at the first receiving terminal caused by the appearance or movement of the perceived target.
[0278] For example, in one embodiment of the present disclosure, the method further includes at least one of the following:
[0279] When the absolute strength of a multipath component received by the first receiving terminal decreases to a first threshold, it is determined that the multipath component received by the first receiving terminal is a multipath component with a multipath component change;
[0280] If a difference between the strength of any one of the multiple multipath components received by the first receiving terminal and the strength of the strongest multipath component among the multiple multipath components is greater than a second threshold, it is determined that any one of the multiple multipath components is a multipath component with a multipath component change.
[0281] In one embodiment of the present disclosure, the first threshold value does not specifically refer to a fixed threshold value. The first value in the first threshold value is used to distinguish it from the second threshold value. The second value in the second threshold value is used to distinguish it from the first threshold value. The first threshold value and the second threshold value may, for example, be predefined, semi-statically configured, or dynamically indicated. This embodiment of the present disclosure does not limit this.
[0282] For example, in one embodiment of the present disclosure, the first threshold value may be, for example, threshold A, and the second threshold value may be, for example, threshold B. Specifically, for a multipath component received by the first receiving terminal, if its absolute strength decreases below threshold A, the first receiving terminal may determine that the multipath component is a multipath component affected by the presence or motion of a perceived target. For a multipath component received by the first receiving terminal, if the difference between the strength of the multipath component and the strength of the strongest multipath component received by the first receiving terminal is greater than threshold B, the first receiving terminal may determine that the multipath component is a multipath component affected by the presence or motion of a perceived target.
[0283] For example, in one embodiment of the present disclosure, the method further includes:
[0284] When the absolute strength of a multipath component received by the first receiving terminal decreases to a first threshold, it is determined that the multipath component received by the first receiving terminal is a multipath component with a multipath component change.
[0285] For example, in one embodiment of the present disclosure, the method further includes:
[0286] If a difference between the strength of any one of the multiple multipath components received by the first receiving terminal and the strength of the strongest multipath component among the multiple multipath components is greater than a second threshold, it is determined that any one of the multiple multipath components is a multipath component with a multipath component change.
[0287] In one embodiment of the present disclosure, determining, based on the first multipath component and the second multipath component, the change information of the multipath component and the parameters of the perceived target includes:
[0288] Determine location information of an environmental target in a reference wireless channel, and determine parameters of the perceived target based on the first multipath component and the second multipath component.
[0289] In one embodiment of the present disclosure, the location information of the environmental target in the reference wireless channel may be determined, and the first receiving terminal may determine the corresponding relationship between the multipath components of the reference wireless channel and the environmental target. Alternatively, based on sensing the reference wireless channel, the first receiving terminal may determine the environmental target and its location in the area to which the first receiving terminal belongs, and establish the corresponding relationship between the multipath components of the reference wireless channel and the environmental target.
[0290] In one embodiment of the present disclosure, based on the current wireless channel and the reference wireless channel, when a perceived target appears or moves, the receiver detects changes in the multipath components of the wireless signal it receives. These changed multipath components are associated with the perceived target and / or environmental targets. For example, the receiver can measure the multipath components of the current wireless channel and compare them with the multipath components measured based on the reference wireless channel to determine the changed multipath components and their associated environmental targets. The new multipath components are directly associated with the perceived target.
[0291] For example, in one embodiment of the present disclosure, for multiple situations in FIG2 , the first receiving terminal can determine the positional relationship between the sensing target and the transmitter, the environmental target, and / or the first receiving terminal based on the first multipath component and the second multipath component. For example:
[0292] For situation (1) in FIG2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the transmitter TX to the environmental target E1.
[0293] For situation (2) in FIG2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the environmental target E2 to the receiver RX.
[0294] For situation (3) in Figure 2, it can be determined that the sensing target T2 is located on the extension line from the transmitter TX to the environmental target E3.
[0295] For situation (4) in FIG2 , it can be determined that the sensing target T3 is located on the extension line from the receiver RX to the environmental target E4.
[0296] For situation (5) in FIG2 , it can be determined that the sensing target T3 is located on the line connecting the transmitter TX to the receiver RX.
[0297] For case (6) in FIG2 , as the perceived target moves, the original multipath component and the new multipath component of the perceived target can be used for joint perception.
[0298] For example, in one embodiment of the present disclosure, the location information of the environmental target, the positional relationship between the perception target and the transmitter, the environmental target and / or the first receiving terminal can be jointly determined together with the multipath component measured by the wireless signal directly reflected by the perception target to determine the location and other parameters of the perception target.
[0299] For example, in one embodiment of the present disclosure, determining parameters of a perception target based on change information of multipath components and location information of an environmental target includes:
[0300] The sensing target blocks the wireless signal of the first environmental target, and the difference between the direction angles of the first multipath component and the second multipath component is greater than the angle difference threshold, thereby determining that the sensing target is located on the line connecting the first transmitting terminal and the first environmental target;
[0301] Parameters of the perception target are determined according to the first multipath component, the first position information of the first environmental target, and the information that the perception target is located on a line connecting the first transmitting terminal and the first environmental target.
[0302] Furthermore, in one embodiment of the present disclosure, FIG4A is a schematic diagram illustrating an example of an assisted sensing operation for environmental target changes provided by the present disclosure. As shown in FIG4A , the first receiving terminal may be, for example, an RX. The first transmitting terminal may be, for example, a TX. As the sensing target reflects a wireless signal to the first receiving terminal, the first receiving terminal may measure the multipath components reflected by the sensing target. These multipath components have different delays, azimuths, and / or Doppler frequencies, for example, different delays, azimuths, and / or Doppler frequencies from those corresponding to the multipath components of the wireless signal reflected by the environmental target in a reference wireless channel. When sensing target T blocks the wireless signal of environmental target E, the first receiving terminal may determine that environmental target E has disappeared or that the signal strength has decreased by more than a first threshold. Therefore, because the azimuths of the new multipath components introduced by the sensing target differ from those of the components of environmental target E (for example, the difference between the azimuths of the new multipath components introduced by the sensing target and the azimuths of the multipath components of environmental target E is greater than an angle difference threshold), it can be determined that the sensing target is located on the line connecting TX and environmental target E, which can be used to assist sensing operations for sensing target T. Based on the measurement of the multipath component reflected by the sensing target T, the position information of the environmental target E, and the information that the sensing target T is located on the line connecting TX to the environmental target E, the first receiving terminal can determine parameters such as the position of the sensing target T.
[0303] For example, in one embodiment of the present disclosure, determining parameters of a perception target based on change information of multipath components and location information of an environmental target includes:
[0304] The perception target blocks the wireless signals of the first environmental target and the second environmental target, and the difference between the directional angles of the first multipath component and the second multipath component of the first environmental target is greater than the angle difference threshold, thereby determining that the perception target is located on the line connecting the first transmitting terminal and the second environmental target; and the difference between the directional angles of the first multipath component and the second multipath component of the second environmental target is less than the angle difference threshold, thereby determining that the perception target is located on the line connecting the first receiving terminal and the first environmental target.
[0305] Determine the parameters of the perception target based on the first multipath component, the first position information of the first environmental target, the second position information of the second environmental target, the information that the perception target is located on the line connecting the first transmitting terminal and the second environmental target, and the information that the perception target is located on the line connecting the first receiving terminal and the first environmental target.
[0306] For example, in one embodiment of the present disclosure, determining parameters of a perception target based on change information of multipath components and location information of an environmental target includes:
[0307] The perception target blocks the wireless signals of the first environmental target and the second environmental target, and the difference between the directional angles of the first multipath component and the second multipath component of the first environmental target is greater than the angle difference threshold, thereby determining that the perception target is located on the line connecting the first transmitting terminal and the second environmental target; and the difference between the directional angles of the first multipath component and the second multipath component of the second environmental target is less than the angle difference threshold, thereby determining that the perception target is located on the line connecting the first receiving terminal and the first environmental target.
[0308] Parameters of the perception target are determined according to information that the perception target is located on a line connecting the first transmitting terminal and the second environmental target and information that the perception target is located on a line connecting the first receiving terminal and the first environmental target.
[0309] Furthermore, in one embodiment of the present disclosure, FIG4B is a schematic diagram illustrating an example of an assisted sensing operation for environmental target changes provided by an embodiment of the present disclosure. As shown in FIG4B , the first receiving terminal may be, for example, RX. The first transmitting terminal may be, for example, TX. As the sensing target reflects wireless signals to the first receiving terminal, the first receiving terminal may measure multipath components reflected by the sensing target. These multipath components have different delays, azimuths, and / or Doppler frequencies, for example, they may differ from the delays, azimuths, and / or Doppler frequencies corresponding to the reference wireless channel. Sensing target T blocks the wireless signals of environmental targets E1 and E2. The first receiving terminal may determine that environmental targets E1 and E2 have disappeared or their signal strengths have decreased by more than a first threshold. Therefore, because the azimuths of the new multipath components introduced by the sensing target differ from those of the multipath components of environmental target E2 (for example, the difference between the azimuths of the new multipath components introduced by the sensing target and those of the multipath components of environmental target E2 is greater than an angle difference threshold), the sensing target may be determined to be located on the line connecting TX and environmental target E2. Since the azimuth angle of the new multipath component introduced by the sensing target is the same as or similar to the azimuth angle of the multipath component of the environmental target E, for example, the difference between the azimuth angle of the new multipath introduced by the sensing target and the azimuth angle of the multipath of the environmental target E1 is less than the angle difference threshold, it can be determined that the sensing target is located on the line connecting RX and the environmental target E1, and these two lines can be used to assist in the sensing operation for the sensing target T. Specifically, based on these two lines, for example, the sensing operation for the sensing target T can be completed. Furthermore, based on the measurement of the multipath component reflected by the sensing target, the position information of the environmental target E, the information that the sensing target is located on the line connecting RX and the environmental target E1, and that the sensing target T is located on the line connecting TX and the environmental target E2, the first receiving terminal can determine parameters such as the position of the sensing target T.
[0310] For example, in one embodiment of the present disclosure, determining parameters of a perception target based on change information of multipath components and location information of an environmental target includes:
[0311] The sensing target blocks the wireless signal between the first transmitting terminal and the first environmental target, the second multipath component of the first environmental target changes, and it is determined that the sensing target is located on the line connecting the first transmitting terminal and the first environmental target;
[0312] Parameters of the perception target are determined according to the first position information of the first environmental target, the multipath component reflected by the perception target sent by the second receiving terminal, and the information that the perception target is located on the line connecting the first transmitting terminal and the first environmental target.
[0313] Furthermore, in one embodiment of the present disclosure, FIG4C is a schematic diagram illustrating an example of an auxiliary sensing operation for environmental target changes provided by the embodiment of the present disclosure. As shown in FIG4C , the first receiving terminal may be, for example, RX1. The second receiving terminal may be, for example, RX2. The first transmitting terminal may be, for example, TX. Due to the influence of obstacles, there is no direct path between receiver RX1 and the sensed target. However, when the sensed target is absent, receiver RX1 can receive the reflected signal from environmental target E. When the sensed target appears, it blocks the wireless signal from environmental target E. Accordingly, the receiver detects that environmental target E has disappeared or that the signal strength has decreased by more than a first threshold. The first receiving terminal can determine that the sensed target is located on the line connecting transmitter TX and environmental target E. By jointly processing this line information, the location information of environmental target E, and the measured values of the multipath components reflected from the sensed target received by other receivers RX2, the first receiving terminal can determine parameters such as the location of the sensed target.
[0314] For example, in one embodiment of the present disclosure, determining parameters of a perception target based on change information of multipath components and location information of an environmental target includes:
[0315] The first environmental target blocks the wireless signals of the sensing target and the transmitting terminal, and the multipath component of the sensing target changes, so that the sensing target is determined to be located on an extension line between the first transmitting terminal and the first environmental target.
[0316] Parameters of the perception target are determined according to the first position information of the first environmental target, the multipath component of the second transmitting terminal reflected by the perception target, and the information that the perception target is located on the extension line of the first transmitting terminal and the first environmental target.
[0317] Furthermore, in one embodiment of the present disclosure, FIG4D is a schematic diagram illustrating an example of an auxiliary sensing operation for environmental target changes provided by an embodiment of the present disclosure. As shown in FIG4D , the first receiving terminal may be, for example, RX. The first transmitting terminal may be, for example, TX1. The second transmitting terminal may be, for example, TX2. Through continuous sensing operations, such as continuous measurement operations, when the sensing target T moves behind the environmental target E, the receiver RX determines that the sensing target T disappears or the signal strength decreases by more than a first threshold. The receiver RX can determine that the sensing target T is located on an extension line between the transmitter TX and the environmental target E. By jointly processing this extension line information, the location information of the environmental target E, and the measurement values of the multipath components reflected by the sensing target T from other transmitters TX2, the first receiving terminal can determine parameters such as the location of the sensing target T.
[0318] For example, in one embodiment of the present disclosure, determining parameters of a perception target based on change information of multipath components and location information of an environmental target includes:
[0319] The sensing target blocks wireless signals of the first transmitting terminal and the first receiving terminal, and determines, based on the first multipath component and the second multipath component, that the sensing target is located on a line connecting the first transmitting terminal and the first receiving terminal;
[0320] Parameters of the perceived target are determined according to the multipath component reflected by the perceived target and information sent by the second receiving terminal that the perceived target is located on a line connecting the first transmitting terminal and the first receiving terminal.
[0321] Furthermore, in one embodiment of the present disclosure, FIG4E is a schematic diagram illustrating an example of an auxiliary sensing operation for environmental target changes provided by an embodiment of the present disclosure. As shown in FIG4E , the first receiving terminal may be, for example, RX1. The second receiving terminal may be, for example, RX2. The first transmitting terminal may be, for example, TX. When the sensing target T is not present, the receiver RX1 may receive the LOS path of the transmitter TX. When the sensing target T appears, it blocks the wireless signal of the transmitter TX. Accordingly, the receiver RX1 determines that the transmitter TX has disappeared or that the signal strength has decreased by more than a first threshold. The receiver RX1 may determine that the sensing target T is located on the line connecting the transmitter TX and the receiver RX1. By jointly processing this line information with the measurement value of the multipath component reflected by the sensing target T received by the other receiver RX2, the receiver RX1 may determine the location and other parameters of the sensing target T.
[0322] For example, in one embodiment of the present disclosure, determining parameters of a perceived target based on change information of multipath components includes:
[0323] Parameters of a perceived target are determined according to the first multipath component and the second multipath component.
[0324] In one embodiment of the present disclosure, the location information of the environmental target in the reference wireless channel may be, for example, undetermined, i.e., the actual location of the environmental target is unknown. The first receiving terminal may jointly process the perceived target and the environmental target to improve the accuracy of parameter determination of the perceived target.
[0325] In one embodiment of the present disclosure, based on the current wireless channel and the reference wireless channel, when a perceived target appears or moves, the first receiving terminal can detect changes in the multipath components of the wireless signal it receives. This multipath component change information reflects the interaction between the perceived target and related environmental objects. For example, the first receiving terminal can measure the multipath components of the current wireless channel and compare them with the multipath components measured based on the reference wireless channel to determine the changed multipath components.
[0326] For example, in one embodiment of the present disclosure, for multiple situations in FIG2 , the first receiving terminal can determine the positional relationship between the sensing target and the transmitter, the environmental target, and / or the first receiving terminal based on the first multipath component and the second multipath component. For example:
[0327] For situation (1) in FIG2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the transmitter TX to the environmental target E1.
[0328] For situation (2) in FIG2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the environmental target E2 to the receiver RX.
[0329] For situation (3) in Figure 2, it can be determined that the sensing target T2 is located on the extension line from the transmitter TX to the environmental target E3.
[0330] For situation (4) in FIG2 , it can be determined that the sensing target T3 is located on the extension line from the receiver RX to the environmental target E4.
[0331] For situation (5) in FIG2 , it can be determined that the sensing target T3 is located on the line connecting the transmitter TX to the receiver RX.
[0332] For case (6) in FIG2 , as the perceived target moves, the original multipath component and the new multipath component of the perceived target can be used for joint perception.
[0333] For example, in one embodiment of the present disclosure, the positional relationship between the perceived target and the transmitter, environmental objects, and / or the first receiving terminal can be combined with multipath components measured for wireless signals directly reflected from the perceived target to determine the position and other parameters of the perceived target. These other parameters may include, for example, velocity.
[0334] For example, in one embodiment of the present disclosure, determining a parameter of a perceived target based on a first multipath component and a second multipath component includes:
[0335] The sensing target blocks the wireless signal of the first environmental target, and the difference between the direction angles of the first multipath component and the second multipath component is greater than the angle difference threshold, thereby determining that the sensing target is located on the line connecting the first transmitting terminal and the first environmental target;
[0336] Parameters of the perceived target are determined according to the first multipath component, the second multipath component, and information that the perceived target is located on a line connecting the first transmitting terminal and the first environmental target.
[0337] Furthermore, in one embodiment of the present disclosure, as shown in FIG4A , if the multipath components of an environmental target E change and the sensing target T is located on the line connecting the transmitter and the environmental target E, this can be used to assist in sensing the sensing target T. For example, based on the measurement of the multipath components reflected by the sensing target T, the changed multipath components, and the information that the sensing target T is located on the line connecting the transmitter and the environmental target E, parameters such as the location of the sensing target T can be determined.
[0338] For example, in one embodiment of the present disclosure, determining a parameter of a perceived target based on a first multipath component and a second multipath component includes:
[0339] The sensing target blocks wireless signals of the first environmental target and the second environmental target, and a difference in direction angle between the first multipath component and the second multipath component of the first environmental target is greater than an angle difference threshold, thereby determining that the sensing target is located on a line connecting the first transmitting terminal and the second environmental target;
[0340] The difference between the direction angle of the first multipath component and the direction angle of the second multipath component of the second environmental target is less than the angle difference threshold, and it is determined that the perception target is located on the line connecting the first receiving terminal and the first environmental target;
[0341] Determine the parameters of the perception target based on the second multipath component corresponding to the first environmental target, the second multipath component corresponding to the second environmental target, the information that the perception target is located on the line connecting the first transmitting terminal and the second environmental target, and the information that the perception target is located on the line connecting the first receiving terminal and the first environmental target.
[0342] For example, in one embodiment of the present disclosure, determining a parameter of a perceived target based on a first multipath component and a second multipath component includes:
[0343] The sensing target blocks wireless signals of the first environmental target and the second environmental target, and determines that the sensing target is located on a line connecting the first transmitting terminal and the second environmental target based on a difference in direction angle between the first multipath component and the second multipath component of the first environmental target being greater than an angle difference threshold;
[0344] The difference between the direction angle of the first multipath component and the direction angle of the second multipath component of the second environmental target is less than the angle difference threshold, and it is determined that the perception target is located on the line connecting the first receiving terminal and the first environmental target;
[0345] Determine the parameters of the perception target based on the first multipath component, the second multipath component corresponding to the first environmental target, the second multipath component corresponding to the second environmental target, the information that the perception target is located on the line connecting the first transmitting terminal and the second environmental target, and the information that the perception target is located on the line connecting the first receiving terminal and the first environmental target.
[0346] Furthermore, in one embodiment of the present disclosure, as shown in FIG4B , the multipath components of environmental targets E1 and E2 change, and the sensing target T is located on the line connecting the transmitter and environmental target E2, and on the line connecting environmental target E1 to the receiver. The above two line information can be used to assist in the sensing operation of the sensing target T. The sensing operation of the sensing target T can be completed based on the changing multipath components and the information of the above two lines. To improve accuracy, the sensing processing device can determine parameters such as the location of the sensing target T based on the measurement of the multipath components reflected by the sensing target T, the changing multipath components, and the information of the two lines.
[0347] For example, in one embodiment of the present disclosure, determining a parameter of a perceived target based on a first multipath component and a second multipath component includes:
[0348] The sensing target blocks the wireless signal between the first transmitting terminal and the first environmental target, and the second multipath component corresponding to the first environmental target changes, and it is determined that the sensing target is located on the line connecting the first transmitting terminal and the first environmental target;
[0349] Parameters of the perception target are determined according to the second multipath component corresponding to the first environmental target, the multipath component reflected by the perception target sent by the second receiving terminal, and information that the perception target is located on a line connecting the first transmitting terminal and the first environmental target.
[0350] Furthermore, in one embodiment of the present disclosure, as shown in FIG4C , the multipath components of the environmental target E change, and the sensing target T is located on the line connecting the transmitter TX and the environmental target E. This line information can be processed jointly with the changing multipath components and the measured values of the multipath components reflected by the sensing target T received by other receivers RX2 to determine parameters such as the location of the sensing target T.
[0351] For example, in one embodiment of the present disclosure, determining a parameter of a perceived target based on a first multipath component and a second multipath component includes:
[0352] The parameters of the perceived target are determined according to the multipath components of the changes in the perceived target and the multipath components reflected by the second transmitting terminal via the perceived target.
[0353] Furthermore, in one embodiment of the present disclosure, as shown in FIG4D , the multipath component of the environmental target T changes, and the changed multipath component is jointly processed with the measurement value of the multipath component reflected by the sensing target T from other transmitters TX2, thereby determining parameters such as the position of the sensing target T.

[0358] FIG3B is a schematic diagram illustrating an example of a method for determining a perception target parameter provided by an embodiment of the present disclosure. In one embodiment of the present disclosure, the method for determining a perception target parameter shown in FIG3B is a parallel scheme to the method for determining a perception target parameter shown in FIG3A . For example, the embodiment shown in FIG3A can be executed separately from the embodiment shown in FIG3B . The difference between the method for determining a perception target parameter shown in FIG3A and the method for determining a perception target parameter shown in FIG3B can be, for example, that the execution subject of the perception operation on the perception target is different.
[0359] FIG3B is a schematic diagram illustrating an example of a method for determining a perception target parameter provided by an embodiment of the present disclosure. As shown in FIG3B , the method may include the following steps:
[0360] Step S3201: The first transmitting terminal transmits a wireless signal;
[0361] Step S3202: The first receiving terminal obtains a first multipath component and a second multipath component;
[0362] Step S3203: The first receiving terminal sends measurement information to the sensing processing device, where the measurement information includes at least one of a first multipath component reflected by the sensing target corresponding to the current wireless channel, other varying second multipath components, a first measurement timestamp corresponding to the current wireless channel, and a second measurement timestamp corresponding to the reference wireless channel.
[0363] In one embodiment of the present disclosure, the measurement information sent by the first receiving terminal may include, for example, a first multipath component of the current wireless channel corresponding to the perceived target reflection and other changing second multipath components.
[0364] In one embodiment of the present disclosure, the measurement information sent by the first receiving terminal may, for example, include a first multipath component corresponding to the perceived target reflection of the current wireless channel, other changing second multipath components, a first measurement timestamp corresponding to the current wireless channel, and a second measurement timestamp corresponding to the reference wireless channel.
[0365] In one embodiment of the present disclosure, the first timestamp can be used, for example, to indicate the measurement timestamp of the current wireless channel. The first timestamp does not specifically refer to a fixed timestamp. For example, when multiple measurements are performed on the current wireless channel, the first timestamp corresponding to each measurement is different. The first in the first timestamp can be used, for example, to distinguish it from the second timestamp.
[0366] Step S3204: The sensing processing device receives measurement information sent by the first receiving terminal;
[0367] In one embodiment of the present disclosure, the execution subject of the perception operation for the perception target may be, for example, a perception processing device, which may be, for example, a central device different from any receiving terminal, and which may be a device that receives measurement information sent by at least one receiving terminal.
[0368] In step S3205, the perception processing device uses the measurement information to perform a perception operation on the perception target.
[0369] In one embodiment of the present disclosure, using measurement information to perform a sensing operation on a sensing target includes:
[0370] The position information of the environmental target in the reference wireless channel is determined, and a sensing operation is performed on the sensing target using the measurement information and the position information of the environmental target.
[0371] For example, in one embodiment of the present disclosure, using measurement information and location information of an environmental target to perform a sensing operation on a sensing target includes:
[0372] The sensing target blocks the wireless signal of the first environmental target, and the difference between the direction angles of the first multipath component and the second multipath component is greater than the angle difference threshold, thereby determining that the sensing target is located on the line connecting the first transmitting terminal and the first environmental target;
[0373] Parameters of the perception target are determined according to the first multipath component, the first position information of the first environmental target, and the information that the perception target is located on a line connecting the first transmitting terminal and the first environmental target.

[0388] Parameters of the perceived target are determined according to the multipath component reflected by the perceived target and information sent by the second receiving terminal that the perceived target is located on a line connecting the first transmitting terminal and the first receiving terminal.

[0419] For example, within a certain area, such as an indoor or outdoor setting, a receiver can sense its location based on received wireless signals. The receiver can detect multipath components in the received wireless signals. Different multipath components differ from other multipath components in at least one of the following aspects: delay, angle, and Doppler frequency. Furthermore, the strength of each multipath component is an important parameter. These multipath parameters, namely delay, angle, Doppler frequency, and strength, reflect the characteristics of the environmental targets and perceived targets in the area.
[0420] Among them, in one embodiment of the present disclosure, the appearance and movement of the perception target will have a mutual impact on the wireless signal propagation of the environmental target. The above Figure 2 is a schematic diagram of the mutual impact between the perception target and the environment. In Figure 2, TX1 represents the transmitter, RX represents the receiver, E, E1, E2, E3 and E4 represent the environmental targets, and T1, T2, T3 and T4 represent the perception target. The following describes the situation where the perception target and the environmental target influence each other. The mutual impact between the perception target and the environmental target may include one or more of the following situations:
[0421] 1) The presence or movement of a sensing target may block or weaken the wireless signal from a transmitter to an environmental target, making the target invisible or weakening the signal at the receiver. For example, in Figure 2, the wireless signal from transmitter TX to environmental target E1 is blocked by sensing target T1.
[0422] 2) The presence and movement of sensing targets may block or weaken the wireless signal reflected from an environmental target to the receiver, causing the environmental target to be invisible at the receiver or the signal to be weak. For example, the wireless signal from environmental target E2 to receiver RX in Figure 2 is blocked by sensing target T1.
[0423] 3) Due to the presence or movement of a sensing target, an environmental object may block or weaken the wireless signal from the transmitter to the sensing target, causing the sensing target to be invisible or the signal to be weak at the receiver. For example, in Figure 2, the wireless signal from transmitter TX to sensing target T2 is blocked by environmental object E3.
[0424] 4) Due to the presence and movement of sensing targets, an environmental object may block or weaken the wireless signal reflected from the sensing target to the receiver, causing the sensing target to be invisible at the receiver or the signal to be weak. For example, the wireless signal reflected from sensing target T3 to receiver RX in Figure 2 is blocked by environmental object E4.
[0425] 5) The presence or movement of a sensing target may block or weaken the wireless signal from the transmitter to the receiver, meaning the receiver detects that the transmitter's direct path of sight (LOS) is invisible or the signal is weakened. For example, in Figure 2, the wireless signal's direct path from transmitter TX to receiver RX is blocked by sensing target T4. This also affects the wireless signal reflected from the sensing target at the receiver. Because the transmitter's wireless signal is blocked or weakened by the sensing target, the signal reflected from the sensing target to the receiver also disappears or weakens, meaning the sensing target becomes invisible or the signal is weakened at the receiver.
[0426] 6) As the sensing target moves, the wireless signal reflected from the sensing target to the receiver changes. For example, the multipath component at the previous moment disappears or weakens, and a new multipath component is generated. For example, when sensing target T1 moves to position T1', the original reflected multipath component disappears, and a new reflected multipath component is generated.
[0427] 7) Due to the presence and movement of sensing targets, some of the wireless signals reflected by the sensing targets may reach certain environmental objects, causing the wireless signal reflected from these environmental objects to be stronger at the receiver. Here, because the path from the transmitter to the sensing target to the environmental object is not a direct path—that is, its delay is greater than the direct path from the transmitter to the environmental object—the receiver can detect the increased wireless signal based on the delay characteristics.
[0428] 8) The wireless signal of the environmental target E at the receiver RX is not affected by the sensing target.
[0429] 9) The wireless signal of the sensing target T1 at the receiver RX is not affected by the environmental targets.
[0430] In some embodiments, when there are multiple transmitters or multiple receivers in the area, the impact of the appearance and movement of the sensing target on different pairs of transmitters and receivers is generally different. The above-mentioned impact on the environmental target and / or the transmitter's received signal at the receiver due to the appearance and movement of the sensing target can be used to assist the sensing operation of the sensing target. It is not general. The embodiments of the present disclosure describe the sensing operation of a pair of transmitters and receivers on the sensing target. The measurement and reporting are applicable to the situation where multiple pairs of transmitters and receivers work together. The judgment of the position and characteristics of the sensing target can be obtained based on the measurement results of a pair of transmitters and receivers; or, the position and characteristics of the sensing target can be obtained by jointly processing the measurement results of multiple pairs of transmitters and receivers, thereby improving the sensing performance. The processing entity for the position and characteristics of the sensing target can be located in one receiver, that is, other receivers can report measurement information to the receiver including the sensing entity. Alternatively, the sensing processing entity can be a central device located in a different device from any receiver, and all receivers must report measurement information to the central device.
[0431] In some embodiments, the receiver may perform multiple measurements on an area. The receiver first obtains a reference wireless channel for the area. The reference wireless channel may be one of the following wireless channels:
[0432] a wireless channel received by the receiver before a sensing target appears, wherein the wireless channel includes wireless signals reflected by environmental targets in the area and / or wireless signals directly received by the receiver from a transmitter;
[0433] The wireless channel received by the receiver before the perceived target moves, including wireless signals reflected from environmental targets in the area, wireless signals directly received from the transmitter, and / or wireless signals reflected from the perceived target before the movement. As shown in Figure 2, the perceived target and environmental targets in the area may affect each other;
[0434] When there are multiple sensing targets, when it is necessary to focus on one or more sensing targets, other sensing targets can actually be processed as environmental targets and thus included in the reference wireless channel.
[0435] In some embodiments, based on the current wireless channel and the reference wireless channel, when a perceived target appears or moves, the receiver can detect changes in the multipath components of the wireless signal it receives. Specifically, the multipath component changes that may occur may include one or more of the situations shown in Figure 2. Specifically, for example, the multipath components can be divided into the following two types:
[0436] Category 1: Multipath components of the current wireless channel directly received by the receiver, which are reflected from the sensing target. For example, in Figure 2, the multipath components are from the transmitter TX1 to the sensing target T1 and then to the receiver RX.
[0437] Category 2: Other changing multipath components other than the multipath components reflected from the sensing target of the current wireless channel directly received by the receiver. For example, the changing multipath components of the environmental targets and / or transmitters at the receiver caused by the appearance and movement of the sensing target. For a multipath component received by the receiver, if its absolute strength is weakened to below threshold A, the receiver may consider the multipath component to be an affected multipath component. Alternatively, for a multipath component received by the receiver, if the difference in strength from the strongest multipath received by the receiver exceeds threshold B, the receiver may consider the multipath component to be an affected multipath component. The threshold A or B may be predefined, semi-statically configured, or dynamically indicated.
[0438] Each of the above multipath components may include one or more of the above multipath components. In some embodiments, a receiver may report at least part of the following parameters to the device where the sensing processing entity is located:
[0439] Timestamp, representing the time when the receiver measures the above two multipath components
[0440] Information such as time delay, angle, Doppler frequency and / or strength of each of the two multipath components mentioned above.
[0441] Therefore, the device where the perception processing entity is located can perform perception operations on the perception target based on the information such as the time delay, angle, Doppler frequency and / or strength of one or more of the above two multipath components.
[0442] In some embodiments, a receiver may perform multiple measurements of an area. Assuming the true location of an environmental target is known, the sensing and processing entity may determine a corresponding relationship between the multipath components of a reference wireless channel and the environmental target. Alternatively, based on sensing of the reference wireless channel, the sensing and processing entity may determine the environmental target and its location within the area and establish a corresponding relationship between the multipath components of the reference wireless channel and the environmental target.
[0443] Based on the current wireless channel and the reference wireless channel, when a perceived target appears or moves, the receiver detects changes in the multipath components of the received wireless signal. These changed multipath components are associated with the perceived target and / or environmental objects. For example, the receiver can measure the multipath components of the current wireless channel and compare them with the multipath components measured based on the reference wireless channel to determine the changed multipath components and their associated environmental objects. The new multipath components are directly associated with the perceived target.
[0444] Based on the changing multipath components, the positional relationship between the sensing target and the transmitter, environmental targets and / or receiver can be obtained. Taking Figure 1 as an example,
[0445] For situation 1) in FIG. 2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the transmitter TX to the environmental target E1 .
[0446] For case 2) in FIG. 2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the environmental target E2 to the receiver RX.
[0447] For case 3) in FIG2 , it can be determined that the sensing target T2 is located on the extension line from the transmitter TX to the environmental target E3.
[0448] For case 4) in FIG2 , it can be determined that the sensing target T3 is located on the extension line from the receiver RX to the environmental target E4.
[0449] For case 5) in FIG. 2 , it can be determined that the sensing target T3 is located on the line connecting the transmitter TX to the receiver RX.
[0450] For case 6) in FIG2 , as the sensing target moves, the original multipath component and the new multipath component of the sensing target can be used for joint sensing.
[0451] The above-mentioned location information of the environmental target, the positional relationship between the perception target and the transmitter, the environmental target and / or the receiver can be jointly determined with the multipath component of the wireless signal directly reflected from the perception target to determine the location and other parameters of the perception target, which may include, for example, speed.
[0452] In some embodiments, FIG4A is a schematic diagram illustrating an assisted sensing operation based on the impact of a sensing target on the received signal of an environmental target at a receiver. As shown in FIG4A , on the one hand, the sensing target reflects a wireless signal to the receiver, thereby detecting new multipath components with different delays, azimuths, and / or Doppler frequencies. On the other hand, the sensing target T blocks the wireless signal of the environmental target E, and accordingly, the receiver detects that the environmental target E has disappeared or that the signal strength has decreased by a certain threshold. In FIG4A , because the azimuths of the new multipath components introduced by the sensing target T differ from the azimuths of the multipath components of the disappeared environmental target E, the sensing target T is definitely located on the line connecting the transmitter and the environmental target E, and can be used to assist in sensing the sensing target T. For example, based on the measurement of the multipath components reflected by the sensing target T, the location of the environmental target E, and the information that the sensing target T is located on the line connecting the transmitter and the environmental target E, parameters such as the location of the sensing target T can be obtained.
[0453] In some embodiments, Figure 4B is another schematic diagram of assisting sensing operations based on the impact of sensing targets on the received signal of environmental targets at a receiver. As shown in Figure 4B , on the one hand, sensing target T reflects wireless signals to the receiver, thereby enabling the receiver to detect new multipath components with different delays, azimuths, and / or Doppler frequencies. On the other hand, sensing target T blocks the wireless signals of environmental targets E1 and E2, resulting in the receiver detecting that environmental targets E1 and E2 have disappeared or their signal strength has decreased by a certain threshold. In Figure 4B , because the azimuths of the new multipath components introduced by sensing target T differ from the azimuths of the disappeared environmental target E2, sensing target T is definitely located on the line connecting the transmitter and environmental target E2. Furthermore, because the azimuths of the new multipath components introduced by sensing target T are the same or approximately the same as the azimuths of the disappeared environmental target E1, sensing target T is located on the line connecting environmental target E1 to the receiver. These two line information can be used to assist sensing operations for sensing target T. In fact, sensing operations for sensing target T can be completed based solely on the information from these two lines. In order to improve accuracy, the perception processing entity can still obtain parameters such as the position of the perception target T based on the measurement of the multipath component reflected by the perception target T, the position information of the environmental target E1 and the environmental target E2, and the information of the two connecting lines.
[0454] In some embodiments, FIG4C is another schematic diagram of an auxiliary sensing operation based on the influence of a sensing target on the received signal of an environmental target at a receiver. As shown in FIG4C , due to the influence of an obstacle, there is no direct path between the receiver RX1 and the sensing target T. However, when the sensing target T is not present, the receiver RX1 can receive the reflected signal of the environmental target E. When the sensing target T appears, it blocks the wireless signal of the environmental target E. Accordingly, the receiver finds that the environmental target E has disappeared or the signal strength has decreased by more than a certain threshold. Based on the above information, it can be determined that the sensing target T is located on the line connecting the transmitter TX and the environmental target E. This connection information can be jointly processed with the location information of the environmental target E and the measurement value of the multipath component reflected by the sensing target T received by other receivers RX2 to obtain parameters such as the location of the sensing target T.
[0455] In some embodiments, Figure 4D is a schematic diagram of an auxiliary sensing operation based on obstruction of a sensing target by an environmental target. As shown in Figure 4D , through continuous sensing operations, when sensing target T moves behind environmental target E, the receiver detects that sensing target T has disappeared or its signal strength has decreased by a certain threshold. Based on this information, it can be determined that sensing target T is located on an extension line between transmitter TX and environmental target E. This extension line information can be combined with the location information of environmental target E and the measured multipath components of other transmitters TX2 reflected by sensing target T to obtain parameters such as the location of sensing target T.
[0456] In some embodiments, Figure 4E is a schematic diagram illustrating an assisted sensing operation based on the impact of a sensing target on the transmitter's LOS path at the receiver. As shown in Figure 4E , when sensing target T is absent, receiver RX1 can receive the LOS path of transmitter TX. When sensing target T appears, it blocks the wireless signal from transmitter TX. Accordingly, receiver RX1 detects that transmitter TX has disappeared or its signal strength has decreased by a certain threshold. Based on this information, it can be determined that sensing target T is located on the line connecting transmitter TX and receiver RX1. This line information can be combined with the measured multipath components reflected by sensing target T received by another receiver RX2 to obtain parameters such as the location of sensing target T.
[0457] In some embodiments, a receiver may perform multiple measurements of an area. Assuming the true location of an environmental target is unknown, the location and other parameters of the environmental target determined based on sensing operations using a reference wireless channel are generally subject to error. One possible approach is to jointly process the perceived target and the environmental target to improve the performance of sensing operations for the perceived target. This approach eliminates the need to determine the location and other parameters of the perceived environmental target in advance.
[0458] Based on the current wireless channel and the reference wireless channel, when a sensing target appears or moves, the receiver detects changes in the multipath components of the received wireless signal. These changes in multipath components reflect the interaction between the sensing target and related environmental objects. For example, the receiver can measure the multipath components of the current wireless channel and compare them with the multipath components measured based on the reference wireless channel to determine the changed multipath components.
[0459] In some embodiments, based on the changing multipath components, the positional relationship between the sensing target and the transmitter, environmental targets and / or receiver can be obtained. Taking Figure 2 as an example,
[0460] For situation 1) in FIG. 2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the transmitter TX to the environmental target E1 .
[0461] For case 2) in FIG. 2 , combined with other information, it can be determined that the sensing target T1 is located on the line connecting the environmental target E2 to the receiver RX.
[0462] For case 3) in FIG2 , it can be determined that the sensing target T2 is located on the extension line from the transmitter TX to the environmental target E3.
[0463] For case 4) in FIG2 , it can be determined that the sensing target T3 is located on the extension line from the receiver RX to the environmental target E4.
[0464] For case 5) in FIG. 2 , it can be determined that the sensing target T3 is located on the line connecting the transmitter TX to the receiver RX.
[0465] For case 6) in FIG2 , as the sensing target moves, the original multipath component and the new multipath component of the sensing target can be used for joint sensing.
[0466] The above-mentioned changing multipath components and the positional relationship between the sensing target and the transmitter, environmental targets and / or receiver can be used together with the multipath components measured for the wireless signal directly reflected from the sensing target to jointly determine the position and other parameters of the sensing target.
[0467] In some embodiments, in FIG. 4A , the multipath components of the environmental target E change, and the sensing target T is located on the line connecting the transmitter and the environmental target E. This can be used to assist in sensing the sensing target T. For example, based on the measurement of the multipath components reflected by the sensing target T, the changed multipath components, and the information that the sensing target T is located on the line connecting the transmitter and the environmental target E, parameters such as the position of the sensing target T are obtained.
[0468] In some embodiments, in FIG4B , the multipath components of environmental targets E1 and E2 change, and the sensing target T is located on the line connecting the transmitter and environmental target E2, and also on the line connecting environmental target E1 to the receiver. Information about these two lines can be used to assist in sensing target T. In practice, sensing target T can be performed solely based on the changing multipath components and information about these two lines. To improve accuracy, the sensing processing entity can still obtain parameters such as the location of sensing target T based on measurements of the multipath components reflected by sensing target T, the changing multipath components, and information about the two lines.
[0469] In some embodiments, in FIG4C , the multipath components of the environmental target E change, and the sensing target T is located on the line connecting the transmitter TX and the environmental target E. This line information can be processed jointly with the changing multipath components and the measured values of the multipath components reflected by the sensing target T received by other receivers RX2 to obtain parameters such as the location of the sensing target T.
[0470] In some embodiments, in FIG4D , the multipath component of the sensing target T changes, and the changed multipath component is jointly processed with the measured value of the multipath component reflected by the sensing target T from other transmitters TX2 to obtain parameters such as the position of the sensing target T.
