[0231] Optionally, the sensing receiving node can also be referred to as a "sensing signal receiving node", a "sensing receiving node", a "sensing signal receiving node", and the like. The disclosure does not limit the name of the sensing receiving node. The sensing sending node can also be referred to as a "sensing signal sending node", a "sensing sending node", a "sensing signal sending node", and the like. The disclosure does not limit the name of the sensing sending node.

[0232] In some embodiments, the first signal can be a signal for sensing measurement.

[0233] In some embodiments, the first signal sent by the second device can be used for sensing the sensing target.

[0234] Optionally, the perception target can be considered as a target that needs to be perceived. For example, the perception target can be a certain building, a certain moving object, an external environment, etc. The external environment can include, for example, temperature, humidity, whether it is raining, etc.

[0235] It can be understood that the first signal reaches the perception target after being transmitted by the second device, and the first signal can be reflected by the perception target so that the first device receives the reflected first signal. The first device can measure the reflected first signal to realize perception of the perception target, such as positioning, etc.

[0236] In some embodiments, the first signal can be reflected by the perception target. For example, the first signal can be reflected by an obstacle.

[0237] In some embodiments, the name of the first signal is not limited, which is, for example, “perception information”, “first signal”, “perception information”, “perception signal”, etc.

[0241] In some embodiments, the first signal can include at least one of the following information: PRS; CSI-RS; perception reference signal.

[0242] S204, the first signal is measured to obtain first information corresponding to the first signal.

[0243] In some embodiments, the first device receives the first signal, and can measure the first signal based on the configuration information, so that the first device can obtain the first information corresponding to the first signal.

[0244] In some embodiments, the first information includes a measurement value obtained by measuring the first signal. Therefore, the first information can represent the measurement of the first signal.

[0245] In some embodiments, the first information can also be referred to as “signal measurement information”, “perception signal measurement information”, “perception signal measurement information”, “measurement value”, “measurement quantity”, etc., which are not limited in the disclosure.

[0246] In some embodiments, the first information can comprise at least one first parameter. The first parameter can be used to indicate which aspect of the first signal is measured by the first device. Each first parameter can correspond to one or more first values. The first value represents a value of the measurement of the first signal by the first device for the first parameter.

[0247] For example, the first signal is a sensing signal, the first device is a sensing receiving node, the first parameter is a time of arrival (ToA), and the first value is a measurement value. The sensing receiving node can measure the sensing signal to obtain the first information. The first information can comprise one or more measurement values of the ToA corresponding to the sensing signal. Different measurement values of the ToA corresponding to the sensing signal correspond to different sensing targets.

[0248] In some embodiments, the configuration information can comprise the first parameter required to be reported by the first device.

[0249] In some embodiments, after the first device receives the first signal, the first device measures the first signal based on the first parameter required to be reported by the first device configured by the second device to obtain the first information corresponding to the first signal.

[0250] In some embodiments, the first parameter can comprise at least one of:

[0251] a time of arrival (ToA) of the first signal;

[0252] a reference signal received power (RSRP) of the first signal;

[0258] In some embodiments, the first parameters can further include a distance between the perception target and the first device. The first device is configured to receive the first signal.

[0260] In some embodiments, the first parameters can further include a moving speed of the perception target.

[0261] In some embodiments, each of the first parameters in the first information can correspond to one or more measurement values. In the case that a first parameter corresponds to multiple measurement values, different measurement values can correspond to different perception targets.

[0262] Optionally, the first device can measure the same perception signal arriving at different times to obtain measurement values corresponding to different perception targets. One perception signal arriving at one time can be used to perceive one perception target. Because the second device sends the perception signal, the perception signal arrives at different perception targets at different times due to different locations of the perception targets. Therefore, the perception signal reflected by different perception targets arrives at the first device at different times.

[0263] For example, the first parameter is ToA of the perception signal. In the case that the perception signal directly arrives at the first device without being reflected by a perception target, ToA-0 is obtained. In the case that the perception signal is used to perceive a first perception target, ToA-1 is obtained. In the case that the perception signal is used to perceive a second perception target, ToA-2 is obtained. Therefore, the first information can include multiple measurement values of ToA, i.e., ToA-0, ToA-1 and ToA-2.

[0264] In some embodiments, the configuration information can further include a threshold related to the value corresponding to the first parameter.

[0265] In some embodiments, the configuration information can not only include which first parameters the first device needs to report, but also include a threshold related to the value corresponding to the first parameter.

[0266] In some embodiments, the threshold is used to determine the first information to be sent.

[0267] In some embodiments, the first device receives the first signal and can measure the first signal based on the configuration information to obtain the first information corresponding to the first signal. Optionally, the at least one first value corresponding to the at least one first parameter included in the first information can include a second value and / or at least one third value.

[0268] Optionally, the second value is a value of the first parameter corresponding to the first signal directly reaching the first device.

[0269] Optionally, the third value is a value of the first parameter corresponding to the first signal reaching the first device after reflecting off a sensing target.

[0270] In some embodiments, the first value in the first information reported by the first device can include: a second value of the first parameter corresponding to the first signal directly reaching the first device, and at least one third value of the first parameter corresponding to the first signal reaching the first device via at least one reflection path.

[0271] In some embodiments, the first value is a value of the first parameter corresponding to the first signal directly reaching the first device.

[0272] In some embodiments, the first value of the first parameter reported by the first device is a value of the first parameter corresponding to the first signal directly reaching the first device. With this scheme, valid measurement results for positioning can be filtered out, so that the positioning result is more accurate.

[0273] In some embodiments, the first condition is satisfied when the difference between the second value and each of the at least one fourth value is greater than a threshold value. Optionally, the at least one fourth value is all or part of the at least one third value.

[0274] In some embodiments, the first condition is satisfied when the difference between the second value and each of the at least one fourth value is greater than a threshold value. Optionally, the at least one fourth value is all or part of the at least one third value.

[0275] In some embodiments, the threshold value can include a first threshold value and a second threshold value, and the first condition is satisfied when at least one of the following conditions is satisfied:

[0276] The second value is greater than the first threshold value.

[0277] Each of the at least one fourth value is greater than the second threshold value. Optionally, the at least one fourth value is all or part of the at least one third value.

[0278] In some embodiments, different threshold values can be configured for measurement values obtained via different paths, for example: a first threshold value is configured to determine whether the second value of the first parameter corresponding to the first signal directly reaching the first device satisfies the condition, and a second threshold value is configured to determine whether the third value of the first parameter corresponding to the first signal reaching the first device via the reflection path satisfies the condition.

[0279] In some embodiments, the first device can report the second value if the second value is greater than the first threshold.

[0280] In some embodiments, the first device can report the third value if the third value is greater than the second threshold. Alternatively, the third value greater than the second threshold can be one or more.

[0281] It can be understood that in the embodiments of the present disclosure, the third value greater than the second threshold is described as the fourth value.

[0282] In some embodiments, the first device can report the second value and the third value if the second value is greater than the first threshold and the third value is greater than the second threshold. The third value can be one or more.

[0283] In some embodiments, the second threshold can be one or more.

[0284] In some embodiments, if the second threshold is one, the third values obtained by the reflected path measurement can correspond to the same second threshold.

[0285] In some embodiments, if the second threshold is multiple, the third values obtained by the reflected path measurement can correspond to different second thresholds.

For example, similar to the positioning measurement in NR. As shown in the method of FIG. 6a, it can include the following steps:

[0433] Step 1), the network node LMF (which can correspond to the third device in the above) can trigger the sensing measurement, and optionally, send the sensing measurement request message (which can correspond to the second message in the above) to the gNB (which can correspond to the second device in the above).

[0434] Step 2), the gNB allocates resources for the sensing measurement of the UE. Optionally, configure the signal for sensing measurement and its resources.

[0435] Step 3), the UE will perform sensing measurement with the configured reference signal (which can correspond to the first signal in the above). The detailed process can be as shown in FIG. 6b.

[0436] Step 4), the UE reports the measurement result to the LMF.

[0437] Step 5), the LMF can calculate the position of the target based on the measurement result reported by the UE.

[0438] The implementation process of the above step 3) will be described in detail below in combination with the content shown in FIG. 6b:

[0439] Step 1: obtain "ToA_direct1" by measuring the arrival time of the direct path (e.g., LOS path / first path) of the sensing reference signal between TRP1 and the UE;

[0440] Step 2-1: obtain "ToA_reflect1-0" by measuring the arrival time of another path (e.g., second arrival) of the sensing reference signal between TRP1 and the UE, which is reflected by target 0;

[0441] • Step 2-2: Obtain ToA_reflect1-1 by measuring the time of arrival of another path (e.g.: the third arrival) of the sensing reference signal between TRP1 and UE reflected by target 1;

[0442] • Note: There is a threshold between the two adjacent paths detected (see Figure 6c).

[0443] • Step 2-3: UE reports ToA_set1 = {ToA_direct1, ToA_reflect1-0, ToA_reflect1-1,... ToA_refract1-K1} to LMF;

[0444] • Step 3: Same as step 2, UE reports ToA_set2 = {ToA_direct2, ToA_reflect2-0, ToA_reflect2-1,... ToA_refract2-K1} to LMF; and

[0445] • ToA_set3 = {ToA_direct3, ToA_reflect3-0, ToA_reflect3-1,... ToA_refract3-K1};

[0446] • Step 4: On the LMF side (e.g.: LPP server), the coordinates of "ellipse 1, ellipse 2, ellipse 3" can be calculated, and then the overlapping points between ellipse 1, ellipse 2, ellipse 3 are checked.

[0447] • Ideally, if there is only one point overlapping all three ellipses, the coordinates of the target (e.g.: target 0) can be known.

[0448] In some embodiments, in order to support the implementation of the above-mentioned position estimation method in a double-static sensing topology network, some parameters can be introduced. These parameters are the parameters that the UE needs to report the related measurement results.

[0449] In some embodiments, the reception time of the downlink sensing reference signal (DL sensing reference signal) of the signal on each transmission path can be introduced. That is: the UE needs to report the measurement results of the reception time of the downlink sensing reference signal of the signal on each transmission path.

[0450] In some embodiments, the DL sensing reference signal reception time of each path is defined as: the time of arrival of the i-th path delay of the resource element carrying the DL sensing measurement signal configured for measurement detected on the UE side.

[0451] Optionally, the first path delay is a power contribution corresponding in time to the first detected path, which can be referred to as a direct time of arrival.

[0452] In some embodiments, a new field or information element can be introduced in the ISAC (ISAC Common IEs Provide Location Information) to indicate the threshold to distinguish the ToA of the first path and the ToA of other paths to be reported.
