After obtaining the UE information in the specified area, the positioning management function network element sends the UE information in the specified area to the sensing function network element in the regional positioning response message.

[0055] Optionally, the positioning management function network element sends the UE information in the specified area to the sensing function network element in the regional positioning response message according to the stored UE information (such as the location information of the UE), which is valid within a valid life cycle.

[0064] Optionally, the event includes at least one of the following:

[0065] The UE moves out of the current cell or tracking area;

[0066] The UE enters the current cell or tracking area.

[0067] Taking the case of obtaining the UE information in the specified area through the third node in a request-based manner as an example, optionally, as shown in Figure 4 the above obtaining the UE information in the specified area can include:

[0068] S401, the perception function network element can send a first query request message to the third node.

[0069] The first query request message includes UE information of a specified area.

[0070] Optionally, the UE information of the specified area can include at least one of the following: an identifier of the specified area, global information of the specified area, and relative information of the specified area. The global information and the relative information of the specified area are described above, and will not be described here.

[0072] Optionally, the UE information sent by the third node can include at least one of the following: a cell identifier where the UE is located, a tracking area identifier, and relative position information of the UE in the cell or the tracking area.

[0073] In this embodiment, the perception function network element can obtain the relative position information of the UE in the specified area through the mobility management network element, determine the target UE participating in the perception measurement based on the relative position information of the UE, and make the target UE participate in the perception measurement, without all UEs performing the perception measurement, thereby reducing resource overhead and UE power consumption.

[0074] In a communication system, the base station can also obtain the relative position information of the UE based on measurement or association information, such as a cell where the UE is located, a relative distance or a relative direction from the base station, etc. Based on this, in an embodiment, the above obtaining UE information in the specified area can include: receiving UE information recommended by the fourth node to participate in the perception signal measurement.

[0075] The fourth node here can be a base station or a transmission and reception point. The fourth node can recommend UE information participating in the perception signal measurement to the perception function network element in an active manner or a passive manner. The passive manner means a reporting manner based on a request of the perception function network element. Optionally, the perception function network element can configure the information of the specified area to the base station or the transmission and reception point, and the base station or the transmission and reception point can recommend UE information participating in the perception signal measurement in the specified area to the perception function network element.

[0076] Taking the request-based manner of obtaining UE information in the specified area through the fourth node as an example, optionally, as shown in Figure 5 the above obtaining UE information in the specified area can include:

[0077] S501, the perception function network element can send a second query request message to the fourth node.

[0078] The second query request message is used to request the fourth node to recommend UE information participating in sensing signal measurement in a specified area, and the second query request message includes at least one of the following: an identifier of the specified area, a location and / or a range of the specified area, a sensing resource, and a sensing resource set.

[0079] Optionally, as shown in Figure 6 The sensing resource refers to a time-frequency domain resource used for sensing measurement, and the sensing resource set refers to a combination of multiple sensing resources.

[0080] S502, the sensing function network element receives the second query response message sent by the fourth node.

[0081] The second query response message includes UE information participating in sensing signal measurement in a specified area recommended by a base station or a transmission and reception point.

[0082] Optionally, the UE information recommended by the fourth node includes at least one of the following combinations:

[0083] an identifier of the UE and relative position information of the UE at the fourth node;

[0084] an identifier of the UE and specified area information where the UE is located;

[0085] an identifier of the specified area and UE information in the specified area;

[0086] an identifier of the UE and sensing resource information suitable for measurement by the UE;

[0087] an identifier of the sensing resource and UE information suitable for measurement of the sensing resource;

[0088] an identifier of the UE and sensing resource set information suitable for measurement by the UE;

[0089] a sensing resource set and UE information suitable for measurement of the sensing resource set.

[0090] The relative position information of the UE is relative to the position information of the fourth node. Optionally, the relative position information can be represented by an angle and a distance relative to the fourth node, or by latitude and longitude information or position coordinate information.

[0091] Optionally, the specified area identifier is used to represent a specified area, and one UE identifier can correspond to one or more specified area information.

[0092] Optionally, the fourth node can also send the second query response message in an active manner. The fourth node actively sending the second query response message can be based on an event or a period.

[0093] Optionally, the event is one of the following:

[0094] The UE's movement distance exceeds the first preset threshold;

[0095] The UE's moving speed changes beyond the second preset threshold;

[0096] The optimal channel measurement signal resources reported by the UE have changed;

[0097] The optimal positioning measurement signal resources reported by the UE have changed.

[0098] This example illustrates a scenario where the base station or transmitting / receiving point sends a second query response message triggered by the event "the best channel measurement signal resource reported by the UE has changed." For instance, suppose the UE needs to measure the channel conditions of beams 1 through 16 and report the measurement results for these 16 beams to the base station or transmitting / receiving point. If at one moment the UE's reported measurement results for these 16 beams show that beam 2 has the best channel, and at the next moment the UE's reported measurement results show that beam 14 has the best channel, then the base station or transmitting / receiving point can determine that the UE's location has changed, causing the measurement difference. Based on this event, the base station or transmitting / receiving point can then send a second query response message to the sensing function network element.

[0099] This example illustrates a scenario where the event "the best positioning measurement signal resource reported by the UE has changed" triggers the base station or transmitting / receiving point to send a second query response message. For instance, the UE needs to measure the positioning status of beams 1 to 8 and report the measurement results for these eight beams. If at one moment the UE's reported measurement results for these eight beams show that beam 2 is the best, and at the next moment the UE's reported measurement results show that beam 8 is the best, then the base station or transmitting / receiving point can determine that the UE's location has changed, causing the measurement discrepancy. Based on this event, the base station or transmitting / receiving point can then send a second query response message to the sensing function network element.

[0100] Optionally, such as Figure 7 As shown, a perception method is also provided, which includes:

[0101] S701, the fourth node sends perception measurement training signals and measurement reporting strategies to the UEs within the designated area.

[0102] The fourth node sends a sensing measurement training signal to find suitable UEs to participate in the sensing measurement process.

[0103] S702. Each UE in the designated area receives the perception measurement training signal and reports the measurement data for the perception measurement training signal to the fourth node according to the measurement reporting strategy.

[0104] The UE receives the sensing measurement training signal and acquires measurement data of the sensing measurement training signal, and reports the measurement data based on a measurement reporting strategy configured by the fourth node.

[0105] Optionally, the measurement reporting strategy configured by the fourth node for the UE can include at least one of the following: reporting measurement data of each path, reporting measurement data of paths exceeding a first signal strength threshold, reporting the number of paths exceeding the first signal strength threshold, and reporting whether there are paths exceeding the first signal strength threshold.

[0106] S703, the fourth node determines the UE to be recommended according to the measurement data of each UE for the sensing measurement training signal, and sends the recommended UE information participating in the sensing signal measurement to the first node.

[0107] After obtaining the measurement data reported by each UE, the fourth node can determine which UEs are suitable for participating in the sensing measurement process according to the measurement data of each UE, or can determine which UEs are not suitable for participating in the sensing measurement process, and all or part of the UEs suitable for participating in the sensing measurement process are taken as the UE to be recommended, and the UE information to be recommended is reported to the sensing function network element. For example, the more the number of paths exceeding the first signal strength threshold that can be measured, the more the UE to be recommended.

[0108] S704, the first node sends the sensing measurement configuration to the target UE.

[0109] S705, the target UE reports the measurement data of the sensing signal.

[0110] In the embodiment, the sensing function network element can also receive the UE information participating in the sensing signal measurement recommended by the fourth node, and determine the target UE participating in the sensing signal measurement based on the recommended UE information, send the sensing measurement configuration to the target UE, and complete the sensing measurement by the target UE, without the need for all UEs to participate in the sensing measurement process, thereby reducing resource overhead and UE power consumption.

[0111] The base station / transmission and reception point is the sensing sending end, and the UE is the sensing receiving end. The UE can also actively report its sensing measurement status information to the base station / transmission and reception point or the sensing function network element. In an embodiment, optionally, the above acquiring UE information in the specified area can include: receiving the sensing measurement status information reported by the UE in the specified area.

[0112] Optionally, the sensing measurement status information includes at least one of the following:

[0113] The measurement range that the UE can currently sense;

[0114] The direction of the UE relative to the fourth reference point;

[0115] a location of the UE relative to a fourth reference point;

[0116] a moving speed of the UE;

[0117] measurement data of the UE for a reference signal.

[0118] Optionally, the measurement range currently perceivable by the UE can comprise at least one of the following: a location of the UE, a measurement area of the UE.

[0119] Optionally, the measurement area of the UE refers to an area that can be measured by the UE, which can comprise at least one of the following: a measurement distance of the UE, a measurement direction of the UE.

[0120] Optionally, the measurement distance of the UE refers to a distance or distance range that can be measured by the UE, and the measurement direction of the UE refers to a direction that can be measured by the UE.

[0121] Optionally, the fourth reference point can be a base station / transmission and reception point to which the UE belongs, or a preset reference point.

[0122] Optionally, the reference signal can be a channel state information-reference signal (CSI-RS), a data and demodulation reference signal (DM-RS), a positioning reference signal (PRS), or the like. Here, the measurement data for the reference signal does not need to report detailed information as required by channel estimation, positioning, and the like, and can comprise at least one of the following: a signal strength and a time delay of a path exceeding a measurement threshold, a number of paths exceeding the measurement threshold, a signal strength and a time delay of a strongest path.

[0123] Optionally, the measurement threshold can be configured by a perception function network element or a base station / transmission and reception point.

[0124] Optionally, the perception measurement status information can be reported in an active manner or in a passive manner. Optionally, the perception measurement status information is reported after the UE satisfies a preset event. Optionally, the UE can periodically report the perception measurement status information of the UE to the perception function network element.

[0125] Optionally, the perception function network element or the base station can configure a reporting condition of the perception measurement status information to the UE, and the UE reports the perception measurement status information after satisfying a preset event.

[0126] Optionally, the preset event can be that a location change of the UE exceeds a location change threshold, or a speed change of the UE exceeds a speed change threshold.

[0127] The awareness function network element selects a target UE participating in the awareness signal measurement based on the awareness measurement condition information reported by the UE, and sends awareness signal receiving configuration to the target UE, so that the target UE completes the awareness signal measurement. All UEs do not need to participate in the awareness measurement, which reduces resource overhead and UE power consumption.

[0128] In the awareness system, as shown in Figure 8 The transmission of radio waves usually has multiple propagation paths between the transmitting and receiving ends, so after the base station sends the awareness signal, the receiving end (such as a UE) will receive multiple path signals with different time delays and power sizes.

[0129] Based on this, in an embodiment, the awareness function network element can also send measurement feedback condition information to the UE.

[0130] The measurement feedback condition information is used by the UE to determine whether to feed back the measurement data for the awareness signal. For example, the UE only reports the measurement data when it is determined that the measurement data for the awareness signal meets the measurement feedback condition information.

[0131] Optionally, the measurement feedback condition information can include at least one of the following:

[0132] A second signal strength threshold value;

[0133] A second signal strength threshold value and a path quantity threshold value exceeding the second signal strength threshold value.

[0134] Optionally, the second signal strength threshold value can be a reference signal receiving power (RSRP) threshold value, a reference signal receiving quality (RSRQ) threshold value, or a signal to interference plus noise ratio (SINR) threshold value, etc.

[0135] Optionally, the second signal strength threshold value is used to indicate that the UE reports the measurement data when there is a path exceeding the second signal strength threshold value in the obtained multi-path measurement information. The measurement data refers to the path exceeding the second signal strength threshold value in the obtained multi-path measurement information.

[0136] Optionally, the second signal strength threshold is used to indicate that the UE reports the measurement data of the path exceeding the second signal strength threshold when there is a path exceeding the second signal strength threshold in the obtained multipath measurement information.

[0137] Optionally, the combination of the second signal strength threshold and the path quantity threshold is used to indicate that the UE reports the measurement data of the path exceeding the second signal strength threshold when there is a path exceeding the second signal strength threshold in the obtained multipath measurement information, and the quantity of the path exceeding the second signal strength threshold also exceeds the path quantity threshold.

[0138] Optionally, the combination of the second signal strength threshold and the path quantity threshold is used to indicate that the UE reports the measurement data of the path exceeding the second signal strength threshold when there is a path exceeding the second signal strength threshold in the obtained multipath measurement information, and the quantity of the path exceeding the second signal strength threshold also exceeds the path quantity threshold. The measurement data refers to the fact that there is a path exceeding the second signal strength threshold in the obtained multipath measurement information, and the quantity of the path exceeding the second signal strength threshold also exceeds the path quantity threshold.

[0139] That is, the base station sends a sensing signal, the UE measures the sensing signal, and when the measurement data of the sensing signal meets the measurement feedback condition information, the UE reports the measurement data of the sensing signal.
