[0014] Herein, exemplary embodiments are described in detail, and examples are shown in the drawings. Where the following description relates to the drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present disclosure. On the contrary, they are merely examples of apparatus and methods consistent with some aspects of the embodiments of the present disclosure.

[0015] The terms used in the embodiments of the present disclosure are only for explaining specific embodiments and are not intended to limit the embodiments of the present disclosure. The singular forms "a kind", "the" and "said" used in the present disclosure are intended to include plural forms as well unless the context clearly indicates otherwise. It should be further understood that the term "and / or" used in this specification refers to any or all possible combinations of one or more of the related listed items.

[0016] It should be understood that in the embodiments of the present disclosure, terms such as the first, the second, the third, etc. may be used to explain various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first parameter may be referred to as the second parameter, and similarly, the second parameter may be referred to as the first parameter. Depending on the context, the word "case" used in this specification may be interpreted as "when...", "and...", or "in response to the determined thing".

[0017] Because a line-of-sight connection exists between the UAV and many base stations, there is a possibility of strong interference to adjacent cells or interference from adjacent cells. LTE UAVs support UE-based solutions, where the UE can estimate interference to other cells by performing downlink measurements to adjacent cells. Since the UE performs measurements anyway when there is an uplink and downlink interaction, estimation based on measurements can be a good, low-latency method.

[0018] Furthermore, LTEUAV also enhances other measurements to mitigate UE interference, for example, by adding altitude-based measurement reporting to help base stations deal with potential interference related to UAVs.

[0019] Referring to FIG. 1, a schematic structural diagram of a wireless communication system according to an embodiment of the present disclosure is shown. As shown in FIG. 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include at least one UE 11 and at least two access network devices 12.

[0020] Here, UE11 may be a device that provides voice and / or data connectivity to the user. UE11 may communicate with one or more core networks via a RadioAccess Network (RAN), through which UE may connect to external network devices such as the Internet and other UEs. UE11 may be an Internet of Things UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an Internet of Things UE, and may be, for example, a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. Examples include Station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 may be a device for an unmanned aerial vehicle (UAV). Alternatively, UE11 may be an in-vehicle device such as a vehicle computer with wireless communication capabilities, or a wireless communication device externally connected to a vehicle computer. Alternatively, UE11 may be a roadside device such as a streetlamp, signal light, or other roadside device with wireless communication capabilities.

[0021] The access network device 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth-generation mobile communication (4G) system, also known as the Long-Term Evolution (LTE) system, or the wireless communication system may be a 5G system, also known as the new radio (NR) system or 5G NR system. Alternatively, the wireless communication system may be an even next-generation system of the 5G system. Here, the access network in the 5G system may be referred to as NG-RAN (New Generation - Radio Access Network). Alternatively, it is a machine type communication (MTC) system.

[0022] Here, the access network device 12 may be an evolved access device (eNB) used in a 4G system. Alternatively, the access network device 12 may be an access device (gNB) with a centralized and distributed architecture used in a 5G system. When the access network device 12 uses a centralized and distributed architecture, the access network device 12 usually includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer, and the distributed unit is provided with a protocol stack of the Physical (PHY) layer. The embodiments of the present disclosure do not limit the specific implementation manner of the access network device 12.

[0023] A wireless connection between the access network device 12 and the UE 11 can be established by using a wireless air interface. In different embodiments, the wireless air interface may be a wireless air interface based on the fourth-generation mobile communications network technology (4G) standard, or it may be a wireless air interface based on the fifth-generation mobile communications network technology (5G) standard, for example, the wireless air interface may be a nuradio, or it may be a wireless air interface based on the 5G next-generation mobile communications network technology standard.

[0024] End-to-end (E2E) or device-to-device (D2D) connections may be established between UE11s. Examples include vehicle-to-everything (V2X) communication scenarios such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P).

[0025] The access network device 12 may be located in a communication system integrated with a satellite communication system, and may be able to provide connectivity services to the satellite and access the satellite to the core network. For example, the access network device 12 may be an access network device having satellite gateway functionality in the communication system, such as a gateway device, a ground station device, or a non-terrestrial network gateway / satellite gateway (NTN-Gateway).

[0026] The above wireless communication system may further include a core network device 13. Multiple access network devices 12 are each connected to the core network device 13.

[0027] For example, the core network device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the core network device may be an Enhanced Serving Mobile Location Centre (E-SMLC) or the like.

[0028] In another example, the core network device 13 may be an Access and Mobility Management Function (AMF), a Location Management Function (LMF), a Gateway Mobile Location Center (GMLC), etc. The embodiments of this disclosure are not limited to the implementation of the core network device 13.

[0029] The network architecture shown in Figure 1 is merely one example to which the embodiments of this disclosure apply, and does not limit the scope of application of the embodiments of this disclosure.

[0030] To facilitate understanding for those skilled in the art, the embodiments of this disclosure enumerate several embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, as those skilled in the art will understand, the embodiments provided by the embodiments of this disclosure may be performed individually, in combination with methods of other embodiments in the embodiments of this disclosure, or individually or in combination with some methods in other related technologies, and the embodiments of this disclosure are not limited thereto.

[0031] In a mobile communication system, to support the mobility of UEs and to obtain the current channel status of surrounding cells in a timely manner, the network is configured to allow UEs to perform Radio Resource Management (RRM) measurements. Idle and inactive UEs can autonomously select or re-select cells based on the RRM measurement results. Connected UEs report the RRM measurement results to the network, assisting the network in making switching decisions. During the measurement process of a connected UE, the network can transmit measurement configuration information to the connected UE via Radio Resource Control (RRC) signaling. Based on the content of the measurement configuration information, the UE performs measurements on the same frequency, different frequencies, and / or different systems, and then reports the measurement results to the network. Measurement can be divided into three aspects: measurement configuration, measurement execution, and measurement reporting.

[0032] The network performs measurement placement using the RRC reconfiguration process, and the measurement placement information includes at least one of the following: measurement target, reporting placement, measurement identifier, measurement on threshold, measurement gap, and measurement gap assignment.

[0033] Each group of measurements is associated and arranged according to an indexing scheme, with the overall index being the measurement identifier. All measurements are fully arranged according to the relationships between the measurement identifiers and are delivered to the UE by the network. Each measurement identifier is simultaneously associated with one target identifier and one reporting placement identifier, indicating the combination of target and reporting placement that needs to be measured. Targets and reporting placements not associated with a measurement identifier can also be delivered to the UE, but the UE will not perform any form of measurement on these placements. Each measurement identifier can only be associated with one target identifier and one reporting placement identifier.

[0034] The UE performs measurements based on measurement placements delivered by the network, obtains cell measurement results, and then reports a baseline evaluation. Measurement reports are divided into event-triggered reports and periodic reports based on the reporting evaluation criteria. The reporting evaluation criteria are determined by the reporting placements that the network sends to the UE.

[0035] Regarding event trigger reporting, RRM events (Events) supported by the NR system may include events A1 / A2 / A3 / A4 / A5 / A6 from the same system and events B1 / B2 from different RATs (RadioAccess Technology).

[0036] Event A1: The measurement result of the serving cell is greater than the threshold. Event A2: The measurement result for the serving cell is below the threshold. Event A3: The measurement result of an adjacent cell is better than that of a SpCell (SpecialCell), and the SpCell may be a PCell (PrimaryCell) or a PSCell (Primary Secondary cell). Event A4: The measurement result of an adjacent cell is greater than the threshold. Event A5: The measurement result of SpCell (which may also be PCell or PSCell) is less than threshold 1, and at the same time, the measurement result of an adjacent cell is greater than threshold 2. Event A6: The measurement result of an adjacent cell is better than the measurement result of a secondary cell (SCell). Event B1: The measurement result of adjacent cells in different RATs is greater than the threshold. Event B2: The measurement result of the primary cell (PCell) is less than threshold 1, and at the same time, the measurement result of an adjacent cell in a different RAT is greater than threshold 2.

[0037] Event-triggered reports may include single reports triggered by an event and periodic reports triggered by an event.

[0038] For a single report triggered by an event, the UE triggers the submission of the measurement report only after a measurement event that meets the network configuration threshold has entered the threshold and persisted for a certain period of time. After the measurement report has been submitted once, the process terminates.

[0039] For event-triggered periodic reporting, the UE triggers the transmission of a measurement report only after a measurement event that meets the network configuration threshold has entered the threshold and persisted for a certain period of time. After the report is triggered, it turns on the timer and measurement count counter between multiple measurements, and the process terminates after the number of reports meets the requirement.

[0040] For periodic reporting, after the network measurement setup is complete, the UE performs measurements at the corresponding frequency points according to the setup and transmits measurement reports according to the predetermined reporting period and interval. If the trigger type is "periodic," after the maximum number of reports has been reached, the UE automatically removes the corresponding measurement identifier in the measurement setup variable.

[0041] In addition to the two measurement report types described above, a single measurement trigger report has been introduced for several specific use cases, including a single measurement trigger report introduced to support the ANR (Automatic Neighbor Relations) function, which is used to trigger a single measurement report when a UE obtains specific cell-related information (including information such as the cell global identifier, the Tracking Area Code (TAC) to which the cell belongs, and the Public Land Mobile Network (PLMN) list to which the cell belongs).

[0042] If the reporting conditions are met, the UE triggers and reports the measurement. The contents of the measurement report are: Measurement identifier and All available serving cell measurement results and, Based on the reported placement, the measurement results of the optimal adjacent cell at each service frequency point that is selectively carried, It includes at least one of the following: the measurement result of an adjacent cell that satisfies the trigger condition.

[0043] Because aerial UEs (UAVs) and many base stations have a line-of-sight connection, they can cause strong interference to neighboring cells or receive interference from neighboring cells. Interference detection can be performed at the base station or estimated by the UE. In base station-based detection, the base station must negotiate with neighboring cells and collect interference from neighboring cells in order to know when an aerial UE has begun to interfere with multiple cells. This method is more accurate but has low real-time capability, high latency, and requires signaling interaction between base stations. Therefore, LTE UAVs support a UE-based solution, where the UE can estimate interference to other cells by performing downlink measurements to neighboring cells. Since the UE is performing measurements anyway when there is an uplink and downlink interaction, estimation based on measurements is a good, low-latency method.

[0044] Airborne UEs can cause interference to multiple adjacent cells, potentially increasing the frequency of measurement reports. Therefore, to address the problem of frequently triggered measurement reports in LTEUAVs, a feature is provided where measurement reports are not sent when one cell satisfies the event, but only after a number of positioned cells have satisfies the event, thereby reducing the number of times measurement reports are triggered.

[0045] The LTE UAV process introduced a mechanism to trigger measurement reports based on the network's request for a number of cells that simultaneously meet the trigger condition (i.e., more than one). However, the corresponding reporting process only triggers a measurement report if the number of cells meeting the trigger condition changes from less than or equal to the deployed number to greater than or equal to the deployed number. Subsequently, even if the number of cells meeting the trigger condition exceeds the deployed number, the UE will not trigger a measurement report.

[0046] However, a large number of measurement reports are triggered when exit conditions are met, and reducing the frequency of measurement reports requires not only reducing the number of measurement reports triggered by meeting measurement events, but also considering the number of measurement reports triggered by meeting exit conditions. There are several solutions to this problem, as follows: Solution a: Trigger a measurement report when the number of cells that meet the exit conditions exceeds a certain number. Solution b: The UE triggers a measurement report only if the previously reported cell meets the exit conditions. Solution c: Trigger a measurement report when the total number of cells that meet the condition is less than a threshold.

[0047] Solutions a and c prevent the UE from updating the measurement results of adjacent cells in a timely manner, leading to delays in measurement results and potentially causing the network to assign an inappropriate target cell to the UE. For example, if an adjacent cell does not meet the threshold, but the UE does not report the measurement results in a timely manner, the network may not be able to obtain the signal strength of this adjacent cell in a timely manner and may assign this adjacent cell as a target cell based on previously reported measurement results, which could lead to a switching failure. Solution b prevents timely updates of highly interfering adjacent cells, and if exit conditions are applied only to units included in the previous measurement report, it becomes difficult to continuously notify of interference.

[0048] Regarding the problem of UEs frequently triggering measurement reports, some solutions result in the UE being unable to continuously report interference, affecting interference detection performance, and potentially allowing the UE to experience interference from unreported cells that the network side is unaware of. Some solutions result in delayed reporting, which could lead the network side to place incorrect switching commands or fail to update interference suppression policies in a timely manner.

[0049] For some measurement reports, such as altitude-based measurement reports, the evaluation and measurement reporting are not related to the applicable cells, and when the UE performs operations related to cell list placement, it may cause measurement anomalies or measurement reporting delays.

[0050] Figure 2 is a schematic flowchart of a measurement reporting method according to an exemplary embodiment. As shown in Figure 2, the method is If the trigger conditions for a measurement report are met, step 201 may include the UE determining whether or not to report the measurement report to the network device based on the measurement report.

[0051] In the technical solution according to the embodiments of this disclosure, when the trigger condition for measurement reporting is met, the UE decides whether or not to report the measurement report to the network device based on the measurement report. In this way, since the UE does not directly perform the measurement report when the trigger condition for measurement reporting is met, the number of frequently triggered measurement reports can be reduced, and unnecessary measurement reports can be reduced.

[0052] In some examples, the UE may be an aerial UE and / or a mobile device for ground travel. Here, the aerial UE may be, for example, an unmanned aerial vehicle. In some other examples, the aerial UE may be a UE carried by a person on board an aircraft.

[0053] In some examples, the UE may be located on the UAV or integrated with the UAV, and for example, the UE may provide data connectivity for controlling the UAV or for communicating with the UAV.

[0054] In some cases, the UE may be the payload of a UAV and may perform functions separate from the UAV.

[0055] The aforementioned UAVs can include any type of unmanned aerial vehicle. For example, a UAV may be an unmanned fixed-wing aircraft, an unmanned airship, an unmanned helicopter, or any other flyable and remotely controlled device.

[0056] In some examples, the UE can perform corresponding measurements and measurement reports according to measurement arrangements delivered via the network. The measurements may include, for example, at least one of cell measurements, altitude measurements, velocity measurements, and position measurements.

[0057] Cell measurement is configured to measure the serving cell and / or adjacent cells. Cell measurement may include same-frequency cell measurement, different-frequency cell measurement, or different-system cell measurement.

[0058] The altitude measurement is configured to measure altitude information of the UE, such as the altitude value and / or altitude offset value of the UE.

[0059] The velocity measurement is configured to measure UE velocity information, such as the UE's velocity and / or velocity change. The UE's velocity may include the UE's horizontal velocity, the UE's vertical velocity, or the UE's velocity in any direction.

[0060] The location measurement is configured to measure the location information of the UE, for example, the location of the UE and / or the amount of change in location. The location of the UE may include at least one of a geographic location and an area identifier.

[0061] In the embodiments of this disclosure, the measurement report of the UE is associated with a measurement identifier. Based on the measurement identifier associated with the measurement report, the UE can transmit the measurement report to the network.

[0062] Here, the measurement identifier is configured so that the network retrieves information from measurement locations stored within itself, and includes, but is not limited to, the measurement target, measurement location, and other details corresponding to this report.

[0063] In some cases, the measurement report of the UE is, Measurement reports triggered based on RRM events, Measurement reports triggered based on altitude, Measurement reports triggered based on speed, Includes at least one of the following: a measurement report triggered based on location.

[0064] In some cases, altitude-based measurement reports may be triggered by either event H1 or event H2.

[0065] Event H1 means that the altitude of the airborne UE exceeds the first threshold, and Event H2 means that the altitude of the airborne UE falls below the second threshold.

[0066] In some cases, a velocity-triggered measurement report may be triggered based on whether the UE's velocity is greater than a first velocity threshold and / or whether the velocity is less than a second velocity threshold.

[0067] In some cases, location-based measurement reports may be triggered by event D1.

[0068] Event D1 means that the distance between the UE and the first reference location is greater than the first distance threshold, and the distance between the UE and the second reference location is less than the second distance threshold.

[0069] In some examples, if the trigger condition for the measurement report is related to the measurement results of an adjacent cell, the measurement report is configured to cause the network to place a cell switching command on the UE, or to cause the network to update an interference suppression policy. Here, the interference suppression policy may be configured to suppress downlink interference to the UE of an adjacent cell and / or uplink interference to the UE of an adjacent cell.

[0070] In some examples, the measurement results of the adjacent cells are The Reference Signal Receiving Power (RSRP) of the adjacent cell, The Reference Signal Received Quality (RSRQ) of adjacent cells, The signal-to-interference plus noise ratio (SINR) of adjacent cells, and at least one of the following:

[0071] In some examples, if the trigger condition for the measurement report is related to the measurement result of an adjacent cell, the measurement report may be a measurement report triggered based on event A3, event A4, event A5, event A6, event B1, or event B2.

[0072] In some examples, if the trigger condition for the measurement report is not related to the cell measurement result, the measurement report may be a measurement report that is triggered based on altitude, velocity, or position. For example, the measurement report may be a measurement report that is triggered based on event H1 or event H2. In this example, the cell measurement result may include the measurement result of the serving cell and / or adjacent cells.

[0073] In the embodiments of this disclosure, the trigger condition for the measurement report may be the trigger condition for reporting the measurement event.

[0074] In some examples, when the UE determines that a cell has met the reporting trigger conditions for a measurement event, it may decide, based on the measurement report, whether or not to report the measurement report to the network device.

[0075] For example, if the measurement event is A3 and the UE has four neighboring cells, it is possible to sequentially determine whether neighboring cells 1 through 4 meet the reporting trigger conditions. If it is determined that neighboring cells 1 and 2 do not meet the reporting trigger conditions and neighboring cell 3 does, it is no longer necessary to continue determining whether neighboring cell 4 meets the reporting trigger conditions; in other words, it is possible to decide whether or not to report the measurement report to the network device based on the measurement report.

[0076] In some other examples, the UE may sequentially determine whether multiple adjacent cells satisfy the reporting trigger condition, and if there are cells that satisfy the reporting trigger condition, then decide whether to report the measurement report to the network device based on the measurement report.

[0077] In some cases, the measurement report includes signal quality values ​​for adjacent cells.

[0078] In some examples, the signal quality value of the adjacent cell is The measured value of the Reference Signal Receiving Power (RSRP) of the adjacent cell, The measured Reference Signal Received Quality (RSRQ) of the adjacent cell, This includes at least one of the following: a measurement of the signal-to-interference plus noise ratio (SINR) of an adjacent cell.

[0079] In some examples, step 201 above is: When the trigger conditions for a measurement report are met, the UE may include deciding whether or not to report the measurement report to the network device based on whether or not the content of the measurement report has changed.

[0080] Thus, since the UE does not directly execute measurement reports, the frequency of triggering measurement reports can be reduced. Also, if the content of the measurement report does not change, the UE does not need to execute the measurement report, and if the content of the measurement report changes, the UE executes the measurement report, and if the measurement report is used for cell switching, the UE can report the changed measurement report to the network in a timely manner, allowing the network to place the appropriate target cell in a timely manner and reducing the occurrence of switching failures. Furthermore, if the measurement report is used for interference estimation, the UE can perform interference reporting without interruption, and the network can update the interference suppression policy in a timely manner.

[0081] In one embodiment, the method is: If the trigger condition for the measurement report relates to the measurement result of an adjacent cell, the step may include determining whether the UE has an arrangement in the list of permitted cells for the measurement event that triggers the measurement report.

[0082] In this embodiment, if the trigger for the UE's measurement report is related to the measurement result of an adjacent cell, the measurement event for triggering the measurement report may be a measurement event other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2.

[0083] Here, any measurement event other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2 may be any event other than one or more of the events listed above.

[0084] In one embodiment, the method is For each measurement identifier in the measurement identifier list, if the reporting type in the reporting configuration corresponding to the measurement identifier is set as the trigger for the event, then for measurement events other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2, perform at least one of the following operations:

[0085] If the measurement placement parameters for the measurement identifier include a related cell in the permitted cell addition / modification list defined therein, the operation of determining that any adjacent cell detected based on the parameters in the measurement target related to the measurement identifier is the applicable cell, If the measurement identifier does not contain any cells in the exclusion cell addition / modification list defined in the measurement placement parameters, perform at least one of the following operations: determine that any adjacent cell detected based on the parameters in the measurement target associated with the measurement identifier is the applicable cell.

[0086] In one embodiment, as shown in Figure 3, in step 201, if the trigger condition for the measurement report is met, the UE decides whether or not to report the measurement report to the network device based on the measurement report. If the trigger condition for a measurement report is met, step 301 may include the UE deciding whether or not to report the current measurement report to the network device based on the contents of the current measurement report and the contents of the previous measurement report.

[0087] In this embodiment, the measurement report described above is a measurement report that the UE needs to send to the network device in response to the trigger condition for the measurement report being met.

[0088] The aforementioned previous measurement report is the measurement report that the UE most recently sent to the network device. It should be understood that the previous measurement report is one that has already been sent to the network device.

[0089] Here, the measurement identifier in the previous measurement report and the measurement identifier in the current measurement report may be the same or different.

[0090] In some examples, the previous measurement report is the one in which the UE sent a measurement identifier related to the most recent measurement report to the network device. In this example, the measurement identifier in the previous measurement report is the same as the measurement identifier in the current measurement report.

[0091] In some cases, the content of this measurement report may include a list of adjacent cells that need to report measurement results.

[0092] In some cases, the content of the previous measurement report may include a list of adjacent cells for which the most recent measurement results were reported.

[0093] In some examples, the adjacent cells that need to report the measurement results may include adjacent cells that satisfy the trigger condition.

[0094] In some examples, the trigger condition may include an entry condition for a measurement event or an exit condition for a measurement event.

[0095] Here, if one adjacent cell satisfies the conditions for entering a measurement event, that adjacent cell moves from a state where it does not satisfy the measurement event to a state where it does.

[0096] Here, if one adjacent cell satisfies the exit condition for the measurement event, that adjacent cell moves from a state that satisfies the measurement event to a state that does not satisfy the measurement event.

[0097] In some examples, step 301 above is: If the trigger conditions for a measurement report are met, the UE may decide whether or not to report the current measurement report to the network device based on whether the content of the current measurement report has changed compared to the content of the previous measurement report.

[0098] For example, if the content of the current measurement report differs from that of the previous measurement report, the UE decides to report the current measurement report to the network device. Alternatively, if the content of the current measurement report does not differ from that of the previous measurement report, the UE decides not to report the current measurement report to the network device.

[0099] For example, if the content of the current measurement report differs from that of the previous measurement report, the UE will report the current measurement report to the network device; or, if the content of the current measurement report does not differ from that of the previous measurement report, the UE will not report the current measurement report to the network device.

[0100] In the embodiments of this disclosure, when the trigger conditions for a measurement report are met, the UE decides whether or not to report the current measurement report to the network device based on the content of the current measurement report and the content of the previous measurement report. If the content of the current measurement report has not changed compared to the content of the previous measurement report, the UE does not need to perform the measurement report. If the content of the current measurement report has changed compared to the content of the previous measurement report, the UE performs the measurement report. In this way, not only can the frequent triggering of measurement reports be reduced, but if the measurement report is used for cell switching, the UE can also report the changed measurement report to the network in a timely manner, allowing the network to place the appropriate target cell for the UE in a timely manner and reducing the occurrence of switching failures. Furthermore, if the measurement report is used for interference estimation, the UE can perform interference reporting without interruption, and the network can update the interference suppression policy in a timely manner.

[0101] In one embodiment, as shown in Figure 4, step 301 may include at least one of steps 301a, 301b, and 301c in determining whether or not to perform the current measurement report based on whether or not the content of the current measurement report has changed compared to the previous measurement report.

[0102] 301a: When the trigger condition for a measurement report is met, the UE decides whether or not to report the current measurement report to the network device based on the adjacent cells in the current measurement report and the adjacent cells in the previous measurement report.

[0103] In some cases, the UE can decide whether or not to report the current measurement report to the network device based on whether the adjacent cells in the current measurement report have changed compared to the adjacent cells in the previous measurement report.

[0104] For example, UE can compare the identification information of adjacent cells included in the current measurement report with the identification information of adjacent cells included in the previous measurement report. If the comparison matches, the adjacent cells in the current measurement report remain unchanged compared to the adjacent cells in the previous measurement report. If the comparison does not match, the adjacent cells in the current measurement report have changed compared to the adjacent cells in the previous measurement report.

[0105] In some examples, in step 301a above, the UE decides whether or not to report the current measurement report to the network device based on the adjacent cells in the current measurement report and the adjacent cells in the previous measurement report.

[0106] If the adjacent cells in the current measurement report have changed compared to the adjacent cells in the previous measurement report, the UE decides to report the current measurement report to the network device.

[0107] This may include one of the following: if the adjacent cells in the current measurement report have not changed compared to the adjacent cells in the previous measurement report, the UE decides not to report the current measurement report to the network device.

[0108] In some cases, the adjacent cells in the current measurement report have changed compared to the adjacent cells in the previous measurement report. The adjacent cells in this measurement report may include one or more combinations of increases, replacements, and omissions compared to the adjacent cells in the previous measurement report.

[0109] As an example, the change is a substitution. For instance, the adjacent cells included in the previous measurement report include cells A, B, and C, and the adjacent cells included in the current measurement report include cells A, D, and E, and as a result, the report of the current measurement results is executed.

[0110] For example, the change is an increase. For instance, the adjacent cells included in the previous measurement report include cells A, B, and C, and the adjacent cells included in the current measurement report include cells A, B, C, and D, and as a result, the report of the current measurement results is executed.

[0111] As an example, the aforementioned change is a omission. For instance, the adjacent cells included in the previous measurement report include cells A, B, and C, and the adjacent cells included in the current measurement report include cells A and B, and as a result, the report of the current measurement results is executed.

[0112] As an example, the changes include increases and substitutions. For instance, the adjacent cells included in the previous measurement report include cells A, B, and C, and the adjacent cells included in the current measurement report include cells A, B, D, and E, and as a result, the report of the current measurement results is performed.

[0113] As an example, the aforementioned changes include omissions and substitutions. The adjacent cells included in the previous measurement report include cells A, B, and C, and the adjacent cells included in the current measurement report include cells A and D, and as a result, the report of the current measurement results is performed.

[0114] 301b: When the trigger condition for a measurement report is met, the UE decides whether or not to report the current measurement report to the network device based on the adjacent cells that satisfy the first condition in the current measurement report and the adjacent cells that satisfy the first condition in the previous measurement report.

[0115] In some cases, the adjacent cells that satisfy the first condition in the previous measurement report are: The first sort of adjacent cells in the previous measurement report may include adjacent cells that are ranked in the top N positions, where N is a positive integer of 1 or more, and where the first sort includes adjacent cells in descending order of their signal quality values ​​in the previous measurement report.

[0116] The adjacent cells that satisfy the first condition in the aforementioned measurement report are: The second sort of adjacent cells in the measurement report may include adjacent cells that are ranked in the top N positions, where the second sort includes adjacent cells in the measurement report in descending order of signal quality value.

[0117] In some examples, the value of N may be 1, 2, or 3, and this embodiment does not limit the specific value of N.

[0118] Here, the signal quality value may be a measured value of a quantifier determined by the UE based on network configuration or protocol agreement, or determined autonomously by the UE.

[0119] In some examples, the measured quantity may be RSRP, RSRQ, or SINR.

[0120] For example, when determining adjacent cells that satisfy the first condition based on RSRP, the UE, before performing the current measurement report, compares the top N adjacent cells determined according to a second sorting order of RSRP values ​​of adjacent cells included in the current measurement report, with the top N adjacent cells determined according to a first sorting order of RSRP values ​​of adjacent cells included in the previous measurement report, to determine whether the adjacent cells that satisfy the first condition included in the current measurement report have changed compared to the adjacent cells that satisfy the first condition included in the previous measurement report.

[0121] In some examples, in step 301b above, the UE may decide whether or not to report the current measurement report to the network device based on the adjacent cells that satisfy the first condition in the current measurement report and the adjacent cells that satisfy the first condition in the previous measurement report. If the adjacent cells that satisfy the first condition in the current measurement report have changed compared to the adjacent cells that satisfy the first condition in the previous measurement report, the UE decides to report the current measurement report to the network device. The UE may also include deciding not to report the current measurement report to the network device if the adjacent cell that satisfies the first condition in the current measurement report has not changed compared to the adjacent cell that satisfies the first condition in the previous measurement report.

[0122] For example, if the adjacent cells included in the previous measurement report are sorted in descending order of RSRP value as cell A, cell B, cell C, etc., and N=2, and the adjacent cells included in the current measurement report are sorted in descending order of RSRP value as cell A, cell B, cell D, cell C, cell E, etc., then the network device will not report the current measurement report.

[0123] For example, if the adjacent cells included in the previous measurement report are sorted in descending order of RSRP value as cell A, cell B, cell C, cell D, where N=2, and the adjacent cells included in the current measurement report are sorted in descending order of RSRP value as cell A, cell D, cell B, cell C, cell E, then the system will report the current measurement report to the network device.

[0124] In some cases, the adjacent cells that satisfy the first condition in the current measurement report have changed compared to the adjacent cells that satisfy the first condition in the previous measurement report. The order of adjacent cells in the top N positions in the first sort is changed compared to the order of adjacent cells in the top N positions in the second sort, if the adjacent cells in the top N positions in the first sort are the same as the adjacent cells in the top N positions in the second sort.

[0125] For example, if the adjacent cells included in the previous measurement report are sorted in descending order of RSRP value as cell A, cell B, cell C, cell D, and so on, with N=2, and the adjacent cells included in the current measurement report are sorted in descending order of RSRP as cell A, cell B, cell C, cell D, cell E, then the network device will not report the current measurement report.

[0126] For example, if the adjacent cells included in the previous measurement report are sorted in descending order of RSRP as cell A, cell B, cell C, cell D, where N=2, and the adjacent cells included in the current measurement report are sorted in descending order of RSRP as cell A, cell D, cell B, cell C, cell E, then the system will report the current measurement report to the network device.

[0127] For example, if the adjacent cells included in the previous measurement report are sorted in descending order of RSRP as cell A, cell B, cell C, cell D, where N=2, and the adjacent cells included in the current measurement report are sorted in descending order of RSRP as cell A, cell D, cell B, cell C, cell E, then the system will report the current measurement report to the network device.

[0128] 301c: If the trigger condition for a measurement report is met, the UE decides whether or not to report the current measurement report to the network device based on the difference between the measurement result of the first adjacent cell that satisfies the second condition in the previous measurement report and the measurement result of the first adjacent cell in the current measurement report.

[0129] Here, the UE can determine the first adjacent cell that satisfies the second condition based on the cell's signal quality value in the previous measurement report.

[0130] In some cases, the first adjacent cell that satisfies the second condition in the previous measurement report is, This is the M-th adjacent cell in the first sort of adjacent cell signal quality values ​​in the previous measurement report, where M is a positive integer greater than or equal to 1.

[0131] The signal quality value of an adjacent cell may be a measurement of a quantifier determined by the UE based on the network configuration or protocol agreement, or determined autonomously by the UE.

[0132] In some examples, the measured quantity may be RSRP, RSRQ, or SINR.

[0133] In some examples, the value of M may be 1, 2, or 3, and this embodiment does not limit the specific value of M.

[0134] For example, when determining an adjacent cell that satisfies the second condition based on RSRP measurements, the UE can sort the adjacent cells included in the previous measurement report in descending order of RSRP value, identify the adjacent cell with the highest RSRP measurement as the first adjacent cell, determine the RSRP measurement for the first adjacent cell included in the current measurement report, and then determine the difference between the two RSRP measurements for the first adjacent cell.

[0135] As an example, in step 301c above, the UE may decide whether or not to report the current measurement report to the network device based on the difference between the measurement result of the first adjacent cell that satisfies the second condition in the previous measurement report and the measurement result of the first adjacent cell in the current measurement report. If the signal quality value of the first adjacent cell in the previous measurement report is less than or equal to the signal quality value of the first adjacent cell in the current measurement report, it is decided not to report the current measurement report to the network device. If the signal quality value of the first adjacent cell in the previous measurement report is greater than the signal quality value of the first adjacent cell in the current measurement report, it is decided to report the current measurement report to the network device. The system may include one of the following: if the difference between the signal quality value of the first adjacent cell in the previous measurement report and the signal quality value of the first adjacent cell in the current measurement report exceeds a preset threshold, the system decides to report the current measurement report to the network device.

[0136] Here, the pre-configured threshold may be set by the network, agreed upon by a protocol, or determined autonomously by the UE.

[0137] In one embodiment, the cell measurement result includes the signal quality value of the adjacent cell, and the measurement report is, Measurement reports are triggered based on the fulfillment of entry conditions for a measurement event, Includes at least one of the following: a measurement report triggered based on the fulfillment of exit conditions for a measurement event.

[0138] Here, the measurement event may be event A3, event A4, event A5, event A6, event B1, or event B2.

[0139] The conditions for entering the aforementioned measurement event are those that cause an adjacent cell to move from a state where it does not satisfy the measurement event to a state where it does satisfy the measurement event.

[0140] The exit condition for the aforementioned measurement event is the condition under which an adjacent cell moves from a state that satisfies the measurement event to a state that does not satisfy the measurement event.

[0141] In one embodiment, the measurement report triggered based on the fulfillment of the entry conditions for the measurement event is the first measurement report triggered based on the fulfillment of the entry conditions for the measurement event.

[0142] For example, in the case of periodic reporting triggered based on the entry conditions of a measurement event, when performing the initial measurement report, it is necessary to decide whether or not to perform the initial measurement report based on whether or not the content of the measurement report has changed. However, when performing measurement reports after the initial measurement report, it is not necessary to decide whether or not to perform the measurement report based on whether or not the content of the measurement report has changed.

[0143] For example, if one or more adjacent cells meet the entry conditions for a measurement event, a decision is made based on the content of the measurement report whether or not to perform the measurement report. If the measurement report is not performed this time, the periodic report timer corresponding to the measurement event is not stopped and the report counter is not reset to zero.

[0144] In one embodiment, the measurement report triggered based on the fulfillment of the exit conditions for the measurement event is triggered when the exit conditions for the measurement event are met, based on an exit report instruction placed by the network by the UE.

[0145] Here, the exit reporting instruction is configured to trigger a measurement report based on the fulfillment of the exit conditions for the measurement event when the UE fulfills the exit conditions for the measurement event.

[0146] In one example, the exit notification instruction may be delivered to the UE by the network using dedicated signaling (e.g., RRC relocation).

[0147] For example, if one or more adjacent cells in the trigger cell list meet the exit conditions for a measurement event, a decision is made on whether or not to perform a measurement report based on whether or not the content of the measurement report has changed.

[0148] In one embodiment, deciding whether or not to perform the measurement report based on whether or not the content of the measurement report has changed is not applicable to periodic measurement reports.

[0149] For example, if a measurement report is triggered by a periodic timer timeout, the system will execute the measurement report directly and will not determine whether or not to execute the measurement report based on its content.

[0150] In one embodiment, the method is If the measurement event associated with a measurement identifier is a first measurement event, the UE may further include ignoring the adjacent cell list arrangement corresponding to the measurement identifier, wherein the first measurement event is different from a second measurement event for an adjacent cell.

[0151] Figure 5 is a schematic flowchart of a measurement reporting method according to an exemplary embodiment. As shown in Figure 5, the method is If the measurement event associated with a measurement identifier is a first measurement event, the UE may include step 501 of ignoring the adjacent cell list arrangement corresponding to the measurement identifier, wherein the first measurement event is different from a second measurement event for an adjacent cell.

[0152] In the technical solution according to the embodiments of this disclosure, if the measurement event associated with a measurement identifier is a first measurement event, the UE ignores the adjacent cell list arrangement corresponding to the measurement identifier. Because the first measurement event is different from the second measurement event for an adjacent cell, it indicates that the first measurement event does not involve the measurement of the adjacent cell, and by ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the first measurement event, the effective execution of the measurement process can be ensured and the occurrence of measurement failures can be reduced.

[0153] In some examples, the UE may be an aerial UE and / or a mobile device for ground travel. Here, the aerial UE may be, for example, an unmanned aerial vehicle. In some other examples, the aerial UE may be a UE carried by a person on board an aircraft.

[0154] In some examples, the UE may be located on the UAV or integrated with the UAV, and for example, the UE may provide data connectivity for controlling the UAV or for communicating with the UAV.

[0155] In some cases, the UE may be the payload of a UAV and may perform functions that allow it to detach from the UAV.

[0156] The aforementioned UAVs can include any type of unmanned aerial vehicle. For example, a UAV may be an unmanned fixed-wing aircraft, an unmanned airship, an unmanned helicopter, or any other flyable and remotely controlled device.

[0157] In some examples, the first measurement event is Altitude-based measurement events, Speed-based measurement events, Includes at least one of the following: a location-based measurement event.

[0158] Altitude-based measurement events are configured to determine whether the altitude information of the UE meets the trigger conditions for a measurement report. For example, the altitude information of the UE may include the altitude value and / or altitude offset value of the UE.

[0159] Altitude-based measurement events are configured to determine whether the UE's velocity information meets the trigger conditions for a measurement report.

[0160] For example, the UE's velocity information may include the UE's velocity and / or velocity change values. The UE's velocity may include the UE's horizontal velocity, the UE's vertical velocity, or the UE's velocity in any direction.

[0161] Location-based measurement events are configured to determine whether the UE's altitude information meets the trigger conditions for measurement reporting.

[0162] For example, UE location information can indicate the UE's location and / or the amount of change in location. The UE's location may include at least one of a geographic location and an area identifier.

[0163] In some examples, the altitude-based measurement event may be either event H1 or event H2.

[0164] Event H1 means that the altitude of the airborne UE exceeds the first threshold, and Event H2 means that the altitude of the airborne UE falls below the second threshold.

[0165] In some examples, a velocity-based measurement event may be that the UE's velocity is greater than a first velocity threshold and / or that the velocity is less than a second velocity threshold.

[0166] In some cases, location-based measurement reports may be triggered by event D1.

[0167] Event D1 means that the distance between the UE and the first reference location is greater than the first distance threshold, and the distance between the UE and the second reference location is less than the second distance threshold.

[0168] In some examples, the second measurement event for an adjacent cell may include one or more of the following: Event A3, Event A4, Event A5, Event A6, Event B1, and Event B2.

[0169] In some examples, the adjacent cell list arrangement is configured to determine the applicable cells.

[0170] In some examples, the UE's ignoring of the adjacent cell list arrangement corresponding to the measurement identifier may include the UE determining the applicable cell without using the adjacent cell list arrangement corresponding to the measurement identifier.

[0171] Embodiments of this disclosure provide a measurement reporting method in which, if the measurement event associated with a measurement identifier is a first measurement event, the UE ignores the adjacent cell list arrangement corresponding to the measurement identifier. Because the first measurement event is different from a second measurement event for an adjacent cell, it indicates that the first measurement event does not involve the measurement of the adjacent cell, and by ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the first measurement event, the effective execution of the measurement process can be ensured and the occurrence of measurement failures can be reduced.

[0172] In one embodiment, the adjacent cell list arrangement is as follows: The placement of the permitted cell list, The arrangement of the excluded cell list and at least one of the following.

[0173] Here, the placement of the allowed cell list and the excluded cell list may be included in the placement of the useAllowedCellList placed by the network.

[0174] In one embodiment, the method is If the measurement event associated with the measurement identifier is the first measurement event, the UE further includes not performing a determination of whether or not it has a list of permitted cells.

[0175] Thus, when the measurement event associated with the measurement identifier is the first measurement event, it indicates that the first measurement event is not involved in cell measurement. Compared to the UE using cells in the permitted cell list and / or excluded cell list based on whether the permitted cell list is present, the UE does not perform the task of determining whether the permitted cell list is present, thereby suppressing abnormalities in the measurement process and further reducing the occurrence of measurement failures.

[0176] In one embodiment, the method is If the trigger conditions for a measurement report are met, the user equipment (UE) may further include deciding whether or not to report the measurement report to the network device based on the measurement report.

[0177] In one embodiment, a measurement reporting method is provided, and the said method is With respect to altitude-based measurement reports, the UE may include ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the said measurement report.

[0178] In one embodiment, a measurement reporting method is provided, and the said method is With respect to speed-based measurement reports, the UE may include ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the measurement report.

[0179] In one embodiment, a measurement reporting method is provided, and the said method is With respect to location-based measurement reports, the UE may include ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the measurement report.

[0180] In one embodiment, a measurement reporting method is provided, and the said method is For measurement events triggered based on altitude, the UE may include ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the measurement event.

[0181] In one embodiment, a measurement reporting method is provided, and the said method is For measurement events triggered based on speed, the UE may include ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the measurement event.

[0182] In one embodiment, a measurement reporting method is provided, and the said method is For measurement events triggered based on location, the UE may include ignoring the adjacent cell list arrangement corresponding to the measurement identifier associated with the measurement event.

[0183] To further illustrate any embodiment of this disclosure, several specific embodiments are provided below.

[0184] Example 1 Embodiments of this disclosure provide a measurement reporting method that determines whether to trigger a measurement report based on the report content, and, assuming the trigger conditions are met, can determine whether to initiate a measurement report based on whether the list of adjacent cells that need to report measurement results has changed, thereby avoiding unnecessary measurement reports, and allowing the network to timely identify the latest adjacent cell interference and adjacent cells that meet the trigger conditions.

[0185] The measurement reporting method relating to the embodiments of this disclosure is: In response to the UE triggering the measurement reporting process, this may include deciding whether or not to perform measurement reporting based on the content of the measurement report.

[0186] In one example, the measurement report is executed only if the adjacent cells included in the measurement report have changed compared to the content of the previous measurement report.

[0187] For example, if the top N adjacent cells with the highest signal intensity included in the measurement report have changed compared to the previous measurement report, a new measurement report will be generated.

[0188] For example, if the change between the measurement results of the optimal adjacent cell in the previous measurement report and the measurement results in the current measurement report exceeds the threshold for placement in the network, a measurement report will be executed.

[0189] Here, the process by which the UE triggers a measurement report includes a measurement report process triggered when the UE meets the entry conditions for a measurement event, and / or a measurement report triggered when the UE meets the exit conditions for a measurement event (if a measurement report instruction is placed in the network).

[0190] In one example, the UE determines the content of the measurement report and decides whether or not to perform the measurement report based on the differences between the content of the current measurement report and the content of the previous measurement report.

[0191] For example, deciding whether or not to perform the current measurement report based on the differences between the contents of the current measurement report and the contents of the previous measurement report is: If the adjacent cells included in this measurement report have changed compared to the previous measurement report, this measurement report will be executed.

[0192] For example, if the adjacent cells included in the previous measurement report are cells A, B, and C, and the adjacent cells included in the current measurement report are cells A, D, and E, then the report will be executed.

[0193] For example, if the adjacent cells included in the previous measurement report are cells A, B, and C, and the adjacent cells included in the current measurement report are cells A, B, C, and D, then the report will be executed.

[0194] For example, if the adjacent cells included in the previous measurement report are cells A, B, and C, and the adjacent cells included in the current measurement report are cells A and B, then the report will be executed.

[0195] In one example, deciding whether or not to perform the current measurement report based on the distinction between the contents of the current measurement report and the contents of the previous measurement report is: If the N adjacent cells with the best measurement results included in this measurement report have changed compared to the previous measurement report, then this measurement report is performed, where N is a positive integer greater than or equal to 1.

[0196] In this embodiment, the measurement results of adjacent cells may include the signal quality values ​​of adjacent cells.

[0197] For example, signal quality values ​​may include measured values ​​of RSRP, RSRQ, and / or SINR.

[0198] In this embodiment, the best measurement results for the N adjacent cells refer to the adjacent cells ranked in the top N positions according to the measured values ​​of RSRP, RSRQ, or SINR of the adjacent cells.

[0199] For example, the N adjacent cells with the best measurement results included in this measurement report are the adjacent cells that rank in the top N positions in terms of the highest RSRP measurements of the adjacent cells in this measurement report.

[0200] The N adjacent cells with the best measurement results included in the previous measurement report are the adjacent cells that are ranked in the top N positions in terms of the highest RSRP measurements of the adjacent cells in the previous measurement report.

[0201] The best N neighboring cells may be determined based on the measured values ​​of the quantifiers to be placed in the network, or based on the measured values ​​of the quantifiers specified in the protocol or determined by the UE.

[0202] Here, a change in the N adjacent cells that yield the best measurement results may mean that the N adjacent cells change and / or that the order of the N adjacent cells changes.

[0203] For example, if the adjacent cells included in the previous measurement report were cells A, B, C, and D in descending order of RSRP, with N=2, and the current cells are A, B, D, C, and E, then the report will not be performed.

[0204] For example, if the adjacent cells included in the previous measurement report were cells A, B, C, and D in descending order of RSRP, with N=2, and the current cells are A, D, B, C, and E, then the report is executed.

[0205] For example, if the adjacent cells included in the previous measurement report were cells A, B, C, and D in descending order of RSRP, with N=2, and the current cells are B, A, D, C, and E, then the report is executed.

[0206] For example, deciding whether or not to perform the current measurement report based on the differences between the content of the current measurement report and the content of the previous measurement report is: This includes determining the adjacent cell with the best measurement result in the previous measurement report and the corresponding first measurement result, determining the second measurement result for this adjacent cell in the current measurement report, and obtaining the difference between the first and second measurement results.

[0207] In this embodiment, the measurement results of adjacent cells may include the signal quality values ​​of adjacent cells.

[0208] For example, the signal quality value may be a measured value of RSRP, RSRQ, and / or SINR.

[0209] In this embodiment, the adjacent cell with the best measurement result in the previous measurement report is the M-th adjacent cell sorted based on the measured values ​​of RSRP, RSRQ, or SINR of the adjacent cell. The value of M may be 1 or 2, etc.

[0210] For example, the adjacent cell with the best measurement result in the previous measurement report is the adjacent cell that ranks first in terms of the highest RSRP measurement value among adjacent cells in the previous measurement report.

[0211] For example, if the first measurement result is worse than the second measurement result, reporting may not be required.

[0212] For example, if the first measurement result is better than the second measurement result, a report is submitted.

[0213] For example, if the first measurement result is better or worse than the second measurement result by a certain threshold, a report is generated.

[0214] For example, deciding whether or not to perform the current measurement report based on the differences between the content of the current measurement report and the content of the previous measurement report applies to the initial measurement report triggered by an event, but not to periodic measurement reports.

[0215] For example, if one or more adjacent cells satisfy a measurement event (entry condition), the system determines whether or not to trigger a measurement report based on the content of the measurement report. If a measurement report is not triggered this time, the system does not stop the periodic reporting timer corresponding to this event, nor does it reset the reporting counter to zero.

[0216] For example, if a measurement report is triggered by a periodic timer timeout, the system will not directly execute the measurement report and will not determine whether or not to execute the measurement report based on its contents.

[0217] For example, deciding whether or not to perform the current measurement report based on the differences between the contents of the current measurement report and the contents of the previous measurement report applies to measurement reports triggered based on the fulfillment of event exit conditions.

[0218] For example, if one or more adjacent cells in the trigger cell list meet the exit conditions for a measurement event, the system determines whether or not to trigger the measurement report once, based on the content of the measurement report.

[0219] For example, if the network has placed an exit reporting instruction, the UE will trigger a measurement report when the exit conditions for the corresponding measurement event are met.

[0220] Example 2 The embodiments of this disclosure provide a measurement reporting method, which is a method that With respect to measurement identifiers associated with event H1 and / or event H2, this may include ignoring the placement of permitted cell lists and / or excluded cell lists corresponding to the said measurement identifiers.

[0221] In one example, for measurement identifiers associated with measurement events triggered based on altitude, the placement of the corresponding allowed cell list and / or excluded cell list is ignored.

[0222] In one example, it is not necessary to determine whether a useAllowedCellList is present for a measurement identifier associated with a measurement event triggered based on altitude.

[0223] In one example, the method may further include at least one of the following: For measurement identifiers associated with speed-triggered measurement events, it is not necessary to determine whether a useAllowedCellList is present.

[0224] For measurement identifiers associated with location-triggered measurement events, it is not necessary to determine whether a useAllowedCellList is present.

[0225] For measurement identifiers associated with location-triggered measurement events, it is not necessary to determine whether a useAllowedCellList is present.

[0226] In one example, it is necessary to determine whether a useAllowedCellList is present for a measurement identifier associated with a measurement event triggered based on signal strength.

[0227] Here, when evaluating the measurement events triggered based on the aforementioned signal strength, it is necessary to consider the signal strength of adjacent cells. For example, the measurement events may be event A3, event A4, event A5, event A6, event B1, event B2, or event X1, etc.

[0228] Event X1 refers to a situation where the measurement value of an Application Layer 2 (L2) U2N relay (UE-to-Network Relay) UE exceeds a threshold.

[0229] In one embodiment, as shown in Figure 6, a measurement reporting method is provided, and this method is If the reporting type in the reporting placement corresponding to one measurement identifier is set to an event trigger, then for measurement events other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2, if the relevant cell is included in the permitted cell addition modification list defined in the measurement placement parameters for that measurement identifier, step 601 determines that any adjacent cell detected based on the parameters in the relevant measurement target is the applicable cell, and / or If the reporting type in the reporting placement corresponding to one measurement identifier is set to an event trigger, and for measurement events other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2, if the relevant cell is not included in the exclusion cell addition / modification list defined in the measurement placement parameters of the measurement identifier, step 602 includes determining that any adjacent cell detected based on the parameters in the relevant measurement target is the applicable cell.

[0230] In this embodiment, for each measurement identifier (measId) in the measurement identifier list (e.g., measIdList) included in the measurement configuration parameter (e.g., VarMeasConfig), if the report type (reportType) in the report configuration (reportConfig) corresponding to this measurement identifier is set as an event trigger (eventtrigger) and the useAllowedCellList is set to true, then at least one of the following operations may be performed for measurement events other than event A1, event A2, event D1, event X2, event H1, or event H2.

[0231] If the relevant cell is included in the allowedCellsToAddModList defined in the measurement placement parameters for the measurement identifier (e.g., VarMeasConfig), it is applied to any adjacent cell found based on the parameters in the relevant measurement object (e.g., measObjectNR). If the relevant cell is not included in the excludedCellsToAddModList defined in the measurement placement parameters for the measurement identifier (e.g., VarMeasConfig), it is determined that any adjacent cell found based on the parameters in the relevant measurement object is the cell to which the modification is applied.

[0232] Here, event X2 refers to the measurement value of the Application Layer 2 (L2) U2N relay (UE-to-Network Relay) UE falling below a threshold.

[0233] For example, a measurement event other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2 may be any one or more events other than Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2.

[0234] Other measurement events besides Event A1, Event A2, Event D1, Event X2, Event H1, or Event H2 may be any one or more events other than Event A1, Event A2, Event D1, Event X2, Event H1, and Event H2.

[0235] for example, 1> for each measId includedin the measIdListwithin VarMeasConfig: 2> if the corresponding reportConfigincludes a reportType setto eventTriggered orperiodical: 3> if the corresponding measObjectconcerns NR: ... 4> if corresponding reportConfig includes reportType set to periodical; or 4> for measurement events other thaneventA1, eventA2, eventD1, eventX2, eventH1 or eventH2: 5> if useAllowedCellList is set totrue: 6> considerany neighboring celldetected based on parameters in the associatedmeasObjectNR to be applicable when the concernedcell is included in the allowedCellsToAddModListdefined within theVarMeasConfig for this measId; 5> else: 6> considerany neighboring celldetected based on parameters in the associatedmeasObjectNR to be applicable when the concernedcell is not included in the excludedCellsToAddModListdefined within theVarMeasConfig for this measId.
