[0186] FIG. 2 is an interaction diagram of a configuration method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a signal processing method, and the method includes:

[0187] In step S2101, the network device sends a first configuration to a receiving end.

[0188] In some embodiments, the receiving end receives a first configuration sent by the network device. In some embodiments, the first configuration can also be referred to as configuration information, first information, etc., and the embodiments of the present disclosure do not make any limitation in this regard.

[0189] In some embodiments, the first configuration is used to configure a parameter range, and the parameter range is used for the receiving end to measure the signal of at least one path. In some embodiments, the parameter range defines the range of measuring the signal of at least one path, which can ensure that the receiving end refers to it when measuring the signal of at least one path, thereby saving the measurement overhead of the receiving end.

[0190] In some embodiments, the signal of each path is generated by backscattering of the first object, and the signal of each path is transmitted by the transmitting end, and the signal of at least one path is used for sensing the first object.

[0191] In some embodiments, the parameter range includes at least one of the following:

[0192] (1) The time delay of at least one path.

[0193] In some embodiments, the time delay of a path refers to the time length between the transmission of the signal from the transmitting end to the receiving end of the receiving end. Alternatively, it can also be understood as the time length required for the signal to be transmitted on the route.

[0194] (2) The time delay range of at least one path.

[0195] For example, the time delay range includes 20ms-40ms, 60ms-100ms, or other numerical values, and the embodiments of the present disclosure do not make any limitation in this regard.

[0196] (3) The Doppler shift of at least one path.

[0197] In some embodiments, the Doppler shift is used to indicate the change of phase and frequency caused by the path difference during the movement of the object.

[0198] (4) The Doppler shift range of at least one path.

[0199] (5) The received power of at least one path.

[0200] In some embodiments, the received power refers to the received power of the signal when the receiving end receives the signal during the transmission of the signal through any path.

[0201] (6) The received power range of at least one path.

[0202] (7) The arrangement order index of the time when at least one path reaches the receiving end.

[0203] In some embodiments, the signals are arranged in the order of arrival after reaching the receiving end through any path, and are indexed in the order.

[0204] For example, the signal reaches through path A first, and the corresponding arrangement order index of path A is 1; the signal reaches through path C second, and the corresponding arrangement order index of path C is 2.

[0205] (8) The range of the arrangement order index of the time when at least one path reaches the receiving end.

[0206] In some embodiments, the first configuration is further used to configure a valid period of the parameter range, and the valid period is used to indicate the time length during which the parameter range is used by the receiving end to measure the signal of at least one path. In the embodiments of the present disclosure, the receiving end measures according to the valid period corresponding to the first configuration, ensures that the measurement is completed within the valid period of the first configuration, and further ensures that the obtained measurement parameter is within the corresponding first configuration, thereby ensuring the accuracy of the obtained measurement result.

[0207] Optionally, the valid period includes a start time and an end time, and the valid period of the first configuration is specified by the start time and the end time. Optionally, the valid period includes a start time and a validity duration, and the end time can be determined by the validity duration, so that the valid period can be determined by the start time and the validity duration.

[0208] It should be noted that different first configurations can be set for the same signal, and the valid periods of different first configurations can be the same or different, which is not limited in the embodiments of the present disclosure.

[0209] In some embodiments, the first configuration includes a plurality of first configurations, and each first configuration corresponds to a first object. In the embodiments of the present disclosure, the network device can configure a plurality of first configurations, and each first configuration can correspond to a first object, that is, there are a plurality of first objects to be perceived, and the parameter range of each first object is configured separately, thereby ensuring the accuracy of the parameter range configured for different first objects.

[0210] In some embodiments, the first configuration is further used to configure a signal. In the embodiments of the present disclosure, the receiving end needs to determine the time-frequency resource of the signal sent by the sending end, and therefore the network device can configure the signal for the receiving end through the first configuration, thereby ensuring that the receiving end can receive the corresponding signal in the corresponding time-frequency resource.

[0211] Optionally, the first configuration includes at least one of the following:

[0212] a start time of the signal;

[0213] a duration of the signal.

[0214] In step S2102, the network device sends the second configuration to the receiving end.

[0215] In some embodiments, the second configuration is used to update a measurement period in which the receiving end measures at least one path and / or a sending period in which the receiving end sends a measurement result of the at least one path.

[0216] Optionally, the measurement period is used to indicate a period in which the receiving end measures each path. In the embodiments of the present disclosure, the network device can configure the measurement period for the receiving end through the second configuration, and then the receiving end can periodically measure the at least one path based on the measurement period.

[0217] Optionally, the sending period is used to indicate a period in which the receiving end sends the measurement result. In the embodiments of the present disclosure, the network device can configure the sending period for the receiving end through the second configuration, and then the receiving end can send the measurement result based on the sending period.

[0218] It should be noted that the second configuration in the embodiments of the present disclosure can also configure a measurement event, and the corresponding measurement result is sent when the measurement event is met.

[0219] In some embodiments, the sending periods of different first objects are different; or, the sending periods of different first objects are the same. In the embodiments of the present disclosure, if multiple first objects need to be perceived, the measurement results of different first objects can be sent according to the same sending period, or the measurement results of different first objects can be sent according to different sending periods. It should be noted that the execution order of steps S2101-S2102 in the embodiments of the present disclosure can be changed, for example, step S2102 is executed first and step S2101 is executed later.

[0220] In step S2103, the sending end sends a signal.

[0221] In the embodiments of the present disclosure, the signal sent by the sending end can be a perception signal or other types of signals, which are not limited in the embodiments of the present disclosure.

[0222] It should be noted that the execution order of steps S2102 and S2103 in the embodiments of the present disclosure can be adjusted, step S2103 can be executed first and step S2102 can be executed later, which are not limited in the embodiments of the present disclosure.

[0223] In step S2104, the first object backscatters the signal to at least one path.

[0224] In the embodiments of the present disclosure, after the sending end sends the signal, the sent signal can reach the first object, and then the first object can backscatter the signal on different paths.

[0225] At step S2105, the receiving end measures the signal of the at least one path based on the first configuration, and obtains a measurement result.

[0226] In the embodiments of the present disclosure, after the receiving end determines the first configuration, the receiving end can obtain the parameter range included in the first configuration, and subsequently, the receiving end can measure the signal of the at least one path based on the parameter range, and obtain a measurement result.

[0227] It should be noted that the parameter range refers to the parameter of the at least one path, and therefore, when the receiving end measures the at least one path based on the parameter range, the measurement result obtained is matched with the parameter range of the first configuration, and therefore, the accuracy of the measurement result obtained can be ensured.

[0228] In some embodiments, the receiving end measures each path in the at least one path, and obtains a measurement result.

[0229] Optionally, the measurement result includes at least one of the following:

[0230] (1) the time delay of each path;

[0231] (2) the Doppler shift of each path;

[0232] (3) the received power of the signal received by each path.

[0233] In some embodiments, the receiving end measures the path located in the parameter range to determine whether the path is visible, and obtains a measurement result.

[0234] Optionally, for one first object, if the parameter range includes multiple paths, if at least one path in the multiple paths is visible, it can be considered that the path in the parameter range is visible, and if none of the paths is visible, it can be considered that the path in the parameter range is not visible.

[0235] Optionally, for one first object, it can be further determined whether each path in the multiple paths with the set parameter range is visible.

[0236] At step S2106, the receiving end sends the measurement result.

[0237] In some embodiments, the measurement result is used for sensing the first object.

[0238] In some embodiments, the measurement result is sent in any of the following manners:

[0240] (2) event-triggered.

[0241] In some embodiments, the event includes at least one of the following:

[0242] (1) At least one path disappears.

[0243] In some embodiments, if at least one path disappears, the receiving end can send the measurement results corresponding to the paths other than the disappeared path.

[0244] Optionally, at least one path disappearing can be understood as at least one path from being able to obtain measurement results to being unable to obtain measurement results.

[0245] (2) At least one path appears.

[0246] In some embodiments, if at least one path appears, the receiving end can send the measurement results corresponding to the appeared path. Alternatively, the receiving end can send the measurement results of all paths.

[0247] (3) The measurement values of the paths at adjacent times are greater than a threshold value.

[0248] In some embodiments, the threshold value is agreed by a communication protocol, or is configured by a network device, or is configured in other manners, and the embodiments of the present disclosure do not limit this.

[0249] (4) The received power of the received signal of at least one path is lower than a first power threshold.

[0255] (7) The time delay of at least one path is higher than a second time delay threshold.

[0256] In some embodiments, the second time delay threshold is agreed by a communication protocol, or is configured by a network device, or is configured in other manners, and the embodiments of the present disclosure do not limit this.

[0257] (8) The Doppler shift is lower than a first shift threshold.

[0258] In some embodiments, the first frequency shift threshold is agreed by a communication protocol, or configured by a network device, or configured in other manners, which are not limited in the embodiments of the present disclosure.

[0270] In some embodiments, the network device can determine the volume, speed, shape, etc. of the first object according to the measurement result, which are not limited in the embodiments of the present disclosure.

For example, the SRN only needs to measure one or more paths in the estimated range, without the need to measure all paths, which can reduce the measurement overhead of the SRN.

[0312] Optionally, the setting parameters can include:

[0313] i. a delay of one or more paths, a delay range;

[0314] ii. a doppler frequency shift of one or more paths, a doppler frequency shift range;

[0315] iii. a received power of one or more paths, a received power range;

[0316] iv. a sorting index of the arrival time of one or more paths at the SRN, a sorting index range.

[0317] It should be noted that when the SRN needs to track multiple SOs, the parameters of one or more paths related to the multiple SOs can be configured respectively.

[0318] In some embodiments, the network can also configure a time period corresponding to the configured parameter range of the to-be-tested SensingRS, including a start time, an end time, or a start time and a valid time length. Within the corresponding time period, the SRN is expected to be able to measure the configured parameters in the above configured range. When the corresponding time period is exceeded, the SRN can not be able to measure the configured parameters in the above configured range. It can be understood that within the corresponding time period, the sensing target is located within the estimated geographical position, so the SRN can measure the configured parameters in the above configured range of the to-be-tested SensingRS (sensing reference signal), and outside the corresponding time period, the sensing target is not within the above estimated geographical position, so the SRN can not be able to measure the above configured parameters in the configured range of the to-be-tested SensingRS, or even not be able to measure the to-be-tested SensingRS. For the same to-be-tested signal, different configured parameter ranges can correspond to different time periods.

[0319] It should be noted that the network device can know the parameter range of different paths due to the following factors: (1) Since the network has performed initial detection on the sensing target, there is prior information related to the sensing target, and the network can configure the network device with the estimated configured parameters of one or more paths related to the SO (i.e., reflected by the SO). (2) For the movement of a sensing target with a predetermined orbit, for example, the movement of a sensing target on a highway, railway, or fixed flight path, the network can accurately predict the range of the configured parameters according to the predetermined movement trajectory.

[0320] In some embodiments, the SRN needs to measure all the information of the paths in the configured parameter range, including the time delay value, the doppler shift value, the received power value, etc.

[0321] Optionally, the measurement method is applicable if the configured parameter is the time delay, the time delay range, the doppler shift, the doppler shift range, the received power, the received power range, the sorting index of the reception time of the path, or the sorting index range.

[0322] In some embodiments, the SRN only needs to detect whether the path in the configured parameter range is still visible.

[0323] Optionally, the measurement method is applicable if the configured parameter is the time delay, the time delay range, the doppler shift, the doppler shift range, the received power, the received power range;

[0324] Optionally, when the configured parameter is the sorting index of the path or the index range, the measurement method is generally not applicable.

[0325] It should be noted that for one SO, if the range of the set parameter contains multiple paths, if at least one of the multiple paths is visible, it can be considered that the range of the set parameter is visible, and if none of the multiple paths is visible, it can be considered that the range of the set parameter is invisible.

[0326] It should be further noted that for one SO, it can be further distinguished whether each path in the multiple paths of the set parameter range is visible.

[0327] In some embodiments, the SRN needs to measure the set parameter of the to-be-measured signal in the corresponding period, and judge the measurement result.

[0328] In some embodiments, the network can dynamically update the measurement period and the reporting period of the SRN. The period of the sensing measurement / reporting is related to the moving speed of the SO. Generally speaking, in order to enable the network to accurately and timely grasp the motion trajectory of the SO, the faster the SO moves, the shorter the measurement and reporting period of the SRN should be.

[0329] Optionally, if the SRN is used to track multiple SOs, the measurement / reporting period can be configured for the SRN, that is, for multiple SOs, the measurement / reporting period is the same. Optionally, since the moving speeds of different SOs can be different, the measurement and reporting periods corresponding to different SOs can also be configured respectively. That is, it can be understood that the measurement and reporting periods are configured in units of sensing targets, rather than in units of SRNs.

[0330] In some embodiments, the sensing reporting content of the SRN includes:

[0331] a) The reporting content can be the delay value, the doppler shift value, the received power value, etc. of each path measured;

[0332] b) The reporting content can be the indication information of whether one or more paths in the set range of the set parameter of the to-be-measured sensing RS are visible;

[0333] c) The reporting content can also directly report the measured original channel. For example, the original channel includes the channel response value on each frequency domain subchannel, the autocorrelation matrix of the MIMO channel, etc.

[0334] In some embodiments, the sensing reporting manner of the SRN includes:

[0335] a) The reporting manner can be periodic reporting according to the network configured reporting period. If the SRN is used to track multiple sensing targets, different reporting periods can be configured for the measurement results of different sensing targets.

[0336] b) The reporting manner can also be event triggered reporting. Possible event types include:

[0337] i. One or more or all of the set of parameters of the set range disappear. The occurrence of this event indicates that the SO disappears. For example, being blocked, moving out of the sensing region, etc.

[0338] ii. One or more of the set of parameters of the set range appear. The occurrence of this event indicates that the SO reappears, for example, moving out of the shadow region, etc.

[0339] iii. The difference between two adjacent measurements exceeds a threshold. The occurrence of this event indicates that the position, moving speed, etc. of the SO between the two adjacent measurement intervals changes beyond the threshold.

[0340] iv. The received power of one or more of the set of parameters of the set range is below a first threshold. This event indicates that the distance between the SO and the SRN exceeds the threshold, or that an occlusion appears between the SO and the SRN, resulting in a penetration loss.

[0341] v. The received power of one or more of the set of parameters of the set range is above a second threshold. This event indicates that the distance between the SO and the SRN is less than the threshold, or that the occlusion between the SO and the SRN disappears.

[0342] vi. The time delay of one or more of the set of parameters of the set range is below a third threshold. The occurrence of this event indicates that the distance between the SO and the SRN is less than the threshold.

[0343] vii. The time delay of one or more of the set of parameters of the set range is above a fourth threshold. The occurrence of this event indicates that the distance between the SO and the SRN is greater than the threshold.

[0344] viii. The Doppler shift is below a fifth threshold. The occurrence of this event indicates that the moving speed of the SO is less than the threshold.

[0345] ix. The Doppler shift is above a sixth threshold. The occurrence of this event indicates that the moving speed of the SO is greater than the threshold.
