[0020] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0021] In the description of the present disclosure, unless otherwise specified, " / " means "or". For example, A / B can mean A or B. "And / or" in this article is only a way to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not limit them to be different.

[0022] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs in this disclosure. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0023] In the new radio (NR), radio resource management (RRM) measurements play a key role in various scenarios. For example, RRM can be used for measurements of serving cells and neighbor cells in the radio resource control (RRC) state, as well as IDLE / INACTIVE mode measurements in the RRC idle state (RRC IDLE) and RRC inactive state (RRC INACTIVE). In addition, RRM measurements are also used in the cell selection and reselection process in the RRC_IDLE and RRC_INACTIVE states.

[0024] The basis for RRM measurements is reference signals, which primarily include synchronization signal blocks (SSBs) and channel state information reference signals (CSI-RSs). Reference signals provide user equipment (UE) with critical information about cell synchronization, signal quality, and channel status, enabling the UE to make accurate measurements and decisions.

[0025] In addition, the measurement task of the UE can be indicated and configured by configuring a series of measurement identifiers (measId) to the UE. A measurement identifier is associated with a specific measurement object configuration and a measurement report configuration, respectively, to ensure the accuracy and effectiveness of the measurement task. The measurement object configuration includes the frequency at which the measurement is performed, the reference signal to be measured (SSB or CSI-RS), the number of reference signals used to derive the radio quality of the cell, and the SSB timing configuration (SMTC) for the UE to perform SSB measurements. The measurement report configuration defines the conditions for triggering measurement report events. These events are triggered based on the cell measurement results, that is, when the measurement results meet the preset triggering conditions, the UE will generate and send a measurement report to the network. The cell measurement results can be derived from the synchronization signal and physical broadcast channel block (SS / PBCH) block or CSI-RS.

[0026] In some embodiments, the measurement report configuration may be configured to be event triggered or periodic.

[0027] In the case where the measurement report configuration is of event-triggered type, the measurement report configuration also includes the configuration of the measurement event (or simply referred to as event). The event configuration includes the type of event or the ID (identifier) ​​of the event. Exemplarily, the description of the measurement event may include:

[0028] Event A3: The quality of the neighboring cell is stronger than the quality of the primary cell (PCell) / primary secondary cell (PSCell) by an offset.

[0029] Event A4: The neighbor cell quality becomes stronger than an absolute threshold.

[0030] Event A5: The PCell / PSCell quality is worse than an absolute threshold 1, and the neighboring cell / secondary cell (SCell) quality is better than another absolute threshold 2.

[0031] Event H1: The UE altitude in the air exceeds a height threshold.

[0032] Event H2: The UE altitude in the air is lower than a height threshold.

[0033] Additionally, measurement events can be configured with entry and exit conditions.

[0034] Exemplarily, the measurement report associated with a measurement identifier (measId) is configured as an event triggered type, and when all measurement results after layer 3 filtering of one or more applicable concerned cells (concerned cells) meet the entry condition of the event during a preset timer (TTT, time to trigger), at least one of the following operations is performed:

[0035] In the case that the measurement report list does not include an entry containing the measurement identifier, an entry corresponding to the measurement identifier is set in the measurement report list.

[0036] In the measurement report list, if the trigger cell list defined for the measurement identifier does not include the above-mentioned related cell, the related cell is set in the trigger cell list defined for the measurement identifier in the measurement report list.

[0037] When the measurement report configuration does not include the number of triggering cells (in NR, this configuration is the Number Of Triggering Cells information element), a measurement event can be triggered and a measurement report can be sent to the network corresponding to the measurement identifier.

[0038] When the measurement report configuration includes the number configuration of triggering cells and the number of cells included in the triggering cell list is greater than or equal to the number configuration of triggering cells, the UE triggers a measurement event and sends a measurement report to the network corresponding to the measurement identifier.

[0039] In another example, when the measurement report configuration associated with the measurement identifier is an event-triggered type, and in the measurement report list, all measurement results of one or more related cells included in the triggering cell list defined for this measurement identifier after layer 3 filtering meet a leaving condition within the triggering time, at least one of the following operations is performed:

[0040] One or more related cells are deleted from the triggering cell list.

[0041] In a case where the measurement report configuration corresponding to the measurement identifier indicates that a measurement report is sent when a leaving condition of the event is satisfied, reporting of the measurement report corresponding to the measurement identifier is triggered.

[0042] If the cell information included in the triggering cell list defined by the measurement identifier in the measurement report list is empty, the entry corresponding to the measurement identifier is deleted from the measurement report list. In addition, if the periodic report timer is running, the periodic report timer is stopped.

[0043] In the NR system, the above-mentioned measurement report list is the VarMeasReportList defined by the standard, and the trigger cell list is the CellsTriggeredList defined by the standard. The UE maintains one or more measurement report lists VarMeasReportList and one or more trigger cell lists contained in the measurement report list. The measurement report list VarMeasReportList contains information about measurements that meet the entry conditions. In some embodiments, VarMeasReportList contains one or more information associated with a measurement identifier, which includes a measurement identifier and a trigger cell list CellsTriggeredList defined for the measurement identifier or associated with the measurement identifier. The trigger cell list CellsTriggeredList is used to record cells that trigger measurement reports. CellsTriggeredList may contain multiple cell identifiers, each identifier corresponding to a cell that triggers a measurement report. When a measurement event meets the preset trigger condition, there is no measurement identifier corresponding to the event in the measurement report list. At this time, the UE can add a table entry for the measurement identifier (measId) corresponding to the event in the measurement report list. When the quality of one or more cells measured by the UE meets the preset trigger conditions, the information of these cells will be included in the CellsTriggeredList and sent to the network as part of the measurement report.

[0044] The measurement report contains the measurement results obtained by the UE after performing the measurement, which may include measurement results of one or more cells. These measurement results may be based on different measurement objects, such as SSB (synchronization signal block) and CSI-RS (channel state information reference signal).

[0045] It should be noted that, in the above process, an event being triggered means that the condition for sending a measurement report has been met, but a measurement report corresponding to the event has not been sent yet.

[0046] In some embodiments, the 3GPP Rel-18 NR protocol introduces a new measurement event type to implement measurement report configurations related to height (the height provided in this disclosure may be height relative to the ground, or altitude), as well as combinations of different measurement report events. The configuration of the introduced new measurement event type may include thresholds for traditional A3 events, A4 events, or A5 events, and thresholds for H1 events or H2 events. The new event configuration only includes one trigger time (time to trigger). The type of the new event may be generally referred to as an AxHy event, where Ax represents A3, A4, A5 or other events, and Hy represents H1 or H2 or other events. Exemplarily, the AxHy event type may include:

[0047] Event A3H1: The neighbor cell quality is better than the SpCell quality by an offset, and the UE's altitude is higher than a threshold.

[0048] Event A3H2: The neighbor cell quality is better than the SpCell quality by an offset, and the UE's altitude is lower than a threshold.

[0049] Event A4H1: The quality of the neighboring cell is better than Threshold 1, and the UE altitude is higher than Threshold 2.

[0050] Event A4H2: The quality of the neighboring cell is better than Threshold 1, and the UE altitude is lower than Threshold 2.

[0051] Event A5H1: The Spcell quality is worse than Threshold 1, the neighboring cell quality is better than Threshold 2, and the UE altitude is higher than Threshold 3.

[0052] Event A5H2: The Spcell quality is worse than Threshold 1, the neighboring cell quality is better than Threshold 2, and the UE altitude is lower than Threshold 3.

[0053] The following examples illustrate the definitions of the above-mentioned AxHy events (such as event A3H1, event A3H2, event A4H1, event A4H2, event A5H, and event A5H2):

[0054] In addition, the entry conditions for the AxHy event include the configured entry conditions related to the Ax threshold and the configured entry conditions related to the Hy threshold. When both the configured entry conditions related to the Ax threshold and the configured entry conditions related to the Hy threshold are met, the entry conditions for AxHy are met. When either the configured exit conditions related to the Ax threshold or the configured exit conditions related to the Hy threshold are met, the exit conditions for AxHy are met.

[0055] For example, the entry conditions related to the AxH1 event and the H1 threshold can be described as follows:

[0056] Ms–Hys>Thresh.

[0057] The exit conditions for the above AxH1 event related to the H1 threshold are:

[0058] Ms+Hys <Thresh。

[0059] The entry conditions for the above AxH2 event related to the H2 threshold are:

[0060] Ms+Hys <Thresh。

[0061] The exit conditions related to the H2 threshold for the above AxH2 event are:

[0062] Ms–Hys>Thresh.

[0063] Where: Ms is the UE height relative to sea level. Hys is the hysteresis parameter. Thresh is the H1 or H2 threshold for the event.

[0064] It should be noted that the AxHy event here can implement highly correlated measurement report configurations. Through this mechanism, the traditional Ax event threshold is associated with the altitude-based threshold, and the network can configure different measurement report configurations for UEs at different altitude ranges.

[0065] When two events associated with the same MO and the same event type are triggered simultaneously or successively (i.e., when the conditions for sending a measurement report are met), it is necessary to clarify which measurement identifier associated with the event to send the measurement report for, or whether to send the measurement report for the measurement identifier associated with the newly triggered event.

[0066] To address this technical issue, in some technologies, when multiple events are configured at the same time, the network will explicitly configure the UE to report all triggered measurement reports, or select the MR configuration corresponding to the minimum value between the UE's altitude and the altitude threshold. This flag applies to all similar events (Hx and AxHy) and MO (AxHy), which will be a separate capability. However, this method is only applicable when multiple events are configured simultaneously, but the problem of how to send measurement reports when multiple events are triggered at different times or triggered simultaneously at times other than the configured time remains unresolved.

[0067] Based on this, the present disclosure provides a method for sending a measurement report, which is applied to a terminal. The method for sending a measurement report includes: determining a comparison result between a first distance and a second distance when an entry condition related to a height threshold of a first measurement event is met; the first distance is the distance between the height threshold of the first measurement event and the height of the terminal; the second distance is the distance between the height threshold of the second measurement event and the height of the terminal; based on the comparison result, determining whether to send a measurement report corresponding to a first measurement identifier associated with the first measurement event. In this way, when multiple measurement events (for example, the first measurement event and the second measurement event) trigger measurement reports simultaneously or successively, when the measurement report triggering condition of a new measurement event is met, the UE can perform a distance comparison to determine whether to send a measurement report corresponding to the first measurement identifier associated with the first measurement event, thereby avoiding directly reporting multiple measurement reports corresponding to all triggering events for height, and avoiding the waste of radio resources caused by reporting unnecessary measurement reports. In addition, before sending the measurement report, the terminal distance can be compared with the already triggered measurement event, thereby improving the accuracy of the measurement report transmission method and providing a more detailed control mechanism for the network.

[0068] The method provided by the embodiment of the present disclosure can be applied to various communication systems. For example, the communication system can be a long term evolution (LTE) system, a 5G (5th Generation Mobile Communication Technology, fifth generation mobile communication technology) communication system, a Wi-Fi system, a communication system related to the third generation partnership project (3GPP), a future evolved communication system (such as: a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. The method provided by the embodiment of the present disclosure is described below using the communication system 100 shown in Figure 1 as an example. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided by the present disclosure.

[0069] FIG1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. As shown in FIG1 , the communication system 100 may include one or more terminals 11 and one or more base stations 12. The base stations 12 may be in communication with the one or more terminals 11.

[0070] In some embodiments, the terminal 11 may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. For example, the terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality terminal, an augmented reality terminal, a wireless terminal used in industrial control, a wireless terminal used in unmanned driving, a wireless terminal used in remote surgery, a wireless terminal used in transportation safety, a wireless terminal used in smart cities, a wireless terminal used in smart homes, etc. The embodiments of the present disclosure do not limit the device form adopted by the terminal.

[0071] The base station 12 can be used to implement functions such as resource scheduling, wireless resource management, and wireless access control of terminal devices. For example, it can be an evolution nodeB (eNB), a next-generation nodeB (gNB), a transmission receive point (TRP), a transmission point (TP), and some other access nodes. Depending on the size of the service coverage area provided, the base station can be divided into a macro base station for providing macro cells (Macro cells), a micro base station for providing micro cells (Pico cells), and a femto base station for providing femto cells (Femto cells). With the continuous evolution of wireless communication technology, future base stations may also adopt other names.

[0072] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices or nodes included in Figure 1 and the names of each device are not restricted. In addition to the functional nodes shown in Figure 1, the communication system may also include other nodes or devices, such as core network devices.

[0073] The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0074] The embodiments provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0075] As shown in FIG2 , the present disclosure provides a method for sending a measurement report, which is applied to a terminal and includes the following S101 - S102 .

[0076] S101 : When an entry condition related to a height threshold of a first measurement event is satisfied, determine a comparison result between a first distance and a second distance.

[0077] The first distance is the distance between the height threshold of the first measurement event and the height of the terminal. The second distance is the distance between the height threshold of the second measurement event and the height of the terminal.

[0078] Exemplarily, the UE is configured with two measurement identifiers measId: measurement identifier measId-1 {MO-1, MR-1}, and measurement identifier measId-2 {MO-1, MR-2}, where measId-1 is associated with MO-1 and MR-1, and measId-2 is associated with MO-1 and MR-2. MR-1 and MR-2 are event trigger types, and the event type is A4H1. The event configured for MR-1 is event 1, which includes A4 threshold-1 and H1 threshold-1. The event configured for MR-2 is event 2, which includes A4 threshold-2 and H1 threshold-2. Assume that H1 threshold-2 is greater than H1 threshold-1.

[0079] Multiple A4H1 events are configured. As shown in Figure 3, when the terminal's height satisfies the entry conditions associated with both H1 threshold-1 and H1 threshold-2, and the entry conditions associated with A4 threshold-1 and A4 threshold-2 are also met, the UE may trigger measurement reports for both measurement identifiers measId-1 and measId-2. At this point, the first distance may be determined based on the distance between the UE's height and H1 threshold-1, and the second distance may be determined based on the distance between the UE's height and H2 threshold-2.

[0080] The measurement report configuration corresponding to the first measurement event is of event triggered type. The configuration includes a first measurement event whose type / name is the first event type. The first measurement event is also configured with a first height threshold, such as an H1 threshold, an H2 threshold, etc., that is, the first measurement event may be a Hy event. A first measurement identifier may also be configured for the UE, associating a first measurement object (MO) with a first measurement report configuration.

[0081] In some embodiments, the first measurement event may further be configured with a first threshold. The first threshold may be understood as a threshold related to radio signal measurement. For example, the first threshold may be a reference signal receiving power (RSRP), a reference signal receiving quality (RSRQ), a signal to interference plus noise ratio (SINR) type threshold, or other types of thresholds. For example, the threshold may be a threshold related to event A3, A4, or A5. That is, the first measurement event may also be an AxHy event.

[0082] In some embodiments, the second measurement event is a measurement event that satisfies at least one of the following conditions:

[0083] The height of the terminal satisfies an entry condition related to a height threshold of a second measurement event;

[0084] The terminal has sent a measurement report corresponding to the second measurement identifier associated with the second measurement event;

[0085] The first measurement report list includes an entry of a second measurement identifier associated with the second measurement event;

[0086] In the first measurement report list, a second triggered cell list defined for the second measurement identifier includes the first cell;

[0087] In the first measurement report list, the second triggered cell list defined for the second measurement identifier includes all cells in the first triggered cell list defined for the first measurement identifier;

[0088] The height of the terminal meets the entry condition related to the height threshold of the second measurement event, and the terminal has sent a measurement report corresponding to the second measurement identifier associated with the second measurement event;

[0089] The first measurement report list includes an entry of a second measurement identifier associated with a second measurement event, and in the first measurement report list, a second triggering cell list defined for the second measurement identifier includes the first cell;

[0090] The first measurement report list includes an entry of a second measurement identifier associated with a second measurement event, and the second measurement event is not configured with information on the number of triggering cells;

[0091] The first measurement report list includes an entry of a second measurement identifier associated with a second measurement event, the number of triggered cells is not configured in the second measurement event, and a second triggered cell list defined for the second measurement identifier in the first measurement report list includes the first cell;

[0092] The first measurement report list includes an entry of a second measurement identifier associated with a second measurement event, the second measurement event is configured with information about the number of triggered cells, and the number of cells in the second triggered cell list defined for the second measurement identifier in the first measurement report list is greater than or equal to the number of triggered cells configured for the second measurement event;

[0093] The first measurement report list includes an entry of a second measurement identifier associated with a second measurement event, the second measurement event is configured with information about the number of triggered cells, and the number of cells in a second triggered cell list defined for the second measurement identifier in the first measurement report list is less than the number of triggered cells configured for the second measurement event;

[0094] The first measurement report list includes an entry of a second measurement identifier associated with a second measurement event, the number of cells in a second triggered cell list defined for the second measurement identifier in the first measurement report list is less than the number of triggered cells configured for the second measurement event, and the second triggered cell list defined for the second measurement identifier in the first measurement report list includes the first cell;

[0095] The second measurement event is configured as periodic reporting, and the periodic reporting timer is running, or the number of measurement reports sent for the second measurement event is less than the preset measurement number.

[0096] In one embodiment, the triggering cell list of the measurement identifier associated with the second measurement event also includes the first cell that triggered the first measurement event. In another embodiment, the first measurement event and the second measurement event have the same measurement event type / ID / name. In yet another embodiment, the first measurement event and the second measurement event are associated with the same measurement object (MO).

[0097] In some embodiments, the first cell provided by the present disclosure may be a cell that currently triggers a first measurement event.

[0098] In some embodiments, the first cell provided by the present disclosure may be a cell in a second triggered cell list defined for a second measurement identifier in the first measurement report list.

[0099] The measurement report configuration corresponding to the second measurement event may also be of an event-triggered type, and the second measurement event may also be configured with a second height threshold, such as an H1 threshold, an H2 threshold, or the like. That is, the second measurement event may be a Hy event. In some embodiments, the first measurement event may also be configured with a threshold related to radio signal measurements, such as a threshold for RSRP, RSRQ, or signal-to-interference-and-noise ratio (SINR), or other types of thresholds. For example, the threshold may be a threshold related to events A3, A4, or A5. That is, the second measurement event may also be an AxHy event. Furthermore, a second measurement identifier may be configured for the UE to associate the second measurement object with the second measurement report configuration.

[0100] In addition, in the NR system, the above-mentioned measurement report list (for example, the first measurement report list) can be VarMeasReportList, and the above-mentioned triggered cell list (for example, the second triggered cell list) can be cellsTriggeredList.

[0101] In some embodiments, the second measurement event further satisfies at least one of the following conditions:

[0102] The second measurement event has the same event type as the first measurement event;

[0103] The second measurement event has the same event name as the first measurement event;

[0104] The second measurement event has the same event identifier as the first measurement event;

[0105] The second measurement event is associated with the same measurement object as the first measurement event;

[0106] The second measurement event is configured to be reported individually when it is triggered simultaneously.

[0107] In one embodiment, in an NR system, a UE is configured with MultiTriggerSingleMeasReport. When multiple measurement events (such as A3 and A4) are triggered simultaneously and all configured with MultiTriggerSingleMeasReport, the MultiTriggerSingleMeasReport mechanism allows the UE (user equipment) to send only one measurement report from the multiple measurement events, rather than sending a report for each triggered event. This reduces network signaling overhead.

[0108] In some embodiments, when an entry condition related to a height threshold of the first measurement event is satisfied and a preset trigger condition is satisfied, a comparison result between the first distance and the second distance is determined.

[0109] The above-mentioned preset trigger conditions may include any of the following:

[0110] An entry condition of a first measurement event is satisfied; wherein the entry condition of the first measurement event includes an entry condition related to a height threshold of the first measurement event;

[0111] The measurement result of the first cell within the triggering time meets the entry conditions of the first measurement event and the entry conditions related to the height threshold of the first measurement event, and the number of triggering cells is not configured for the first measurement event;

[0112] The first measurement event is configured with information about the number of triggered cells, and the number of cells in the first triggering cell list defined for the first measurement identifier is greater than or equal to the number of triggering cells configured for the first measurement event;

[0113] When the terminal decides whether to send a measurement report for the first measurement identifier associated with the first measurement event;

[0114] A measurement report trigger condition of a first measurement event is satisfied;

[0115] When the first measurement event is configured with a periodic reporting condition, the periodic reporting condition is met.

[0116] That is, in a scenario where the entry condition related to the height threshold of the first measurement event is met, a comparison result between the first distance and the second distance can be determined to execute the measurement report sending method provided by the present disclosure.

[0117] Alternatively, in a scenario where the entry conditions of the first measurement event are met, a comparison result between the first distance and the second distance can be determined to execute the measurement report sending method provided by the present disclosure. Exemplarily, the first measurement event can be a Hy event, so that the entry conditions of the first measurement event can be entry conditions related to the height threshold. Alternatively, the first measurement event can also be an AxHy event, so that the entry conditions of the first measurement event can include entry conditions related to the height threshold and entry conditions related to the first threshold (or referred to as a threshold related to radio signal measurement) such as RSRP, RSRQ, SINR and other parameter thresholds.

[0118] Alternatively, in a scenario where the measurement result of the first cell after layer 3 filtering meets the entry conditions of the first event within the trigger time, the entry conditions related to the height threshold of the first event are met, and the first event is not configured with the number of triggered cells, the comparison result between the first distance and the second distance can be determined to execute the measurement report sending method provided by the present disclosure.

[0119] Alternatively, in a scenario where the first measurement event is configured with information about the number of triggering cells, and the number of cells in the first triggering cell list defined by the first measurement identifier is greater than or equal to the number of triggering cells configured by the first measurement event, the comparison result between the first distance and the second distance can be determined to execute the measurement report sending method provided in the present disclosure.

[0120] Alternatively, in a scenario where the first event is configured with periodic reporting and the number of triggering cells whose periodic reporting timer times out (and triggers reporting of the measurement report), the comparison result between the first distance and the second distance can be determined to execute the measurement report sending method provided in the present disclosure.

[0121] It should be noted that in the RRC protocol of Rel-18, it is described that after the AS is securely activated, the terminal can trigger a measurement report based on the configured measurement object and report configuration. When the measurement report configuration contains an event trigger or a periodic report type, and the measurement object is related to NR, the UE will check whether events related to altitude (such as eventH1, eventH2, etc.) or traditional A3, A4, A5 events combined with altitude (such as eventA3H1, eventA4H2, etc.) are configured. If these events are configured and the triggering conditions of the events are met, the UE will decide how to handle multiple simultaneously triggered events according to the setting of simulMultiTriggerSingleMeasReport. If simulMultiTriggerSingleMeasReport is set to true, the UE will only consider the event with the smallest difference between the UE's altitude and the corresponding altitude threshold as the event that triggers the measurement report, which helps to reduce redundant reports in the network and optimize performance.

[0122] The above process includes the following:

[0123] If AS security has been activated successfully, the UE shall:

[0124] 1>for each measId included in the measIdList within VarMeasConfig:

[0125] 2>if the corresponding reportConfig includes a reportType set to eventTriggered or periodical:

[0126] 3>if the corresponding measObject concerns NR:

[0127] <irrelevant part>

[0128] 4>if the eventH1 or eventH2 is configured in the corresponding reportConfig:

[0129] 5>for all the events of the same type for which simulMultiTriggerSingleMeasReport is set to true and the entry condition applicable for the event has been satisfied:

[0130] 6>consider only the event with the smallest value between the altitude of the UE and the corresponding altitude threshold to be applicable;

[0131] 4>else if the eventA3H1 or eventA3H2 or eventA4H1 or eventA4H2 or eventA5H1 or eventA5H2 is configured in the corresponding reportConfig:

[0132] 5>for all the events of the same type associated with the same measObjectNR for which simulMultiTriggerSingleMeasReport is set to true and the entry conditions applicable for the event has been satisfied:

[0133] 6>consider only the event with the smallest value between the altitude of the UE and the corresponding altitude threshold to be applicable;

[0134] <irrelevant part>

[0135] The terminal can select an event (measurement report configuration) to apply from multiple events that meet the entry conditions. However, the selected event may not be triggered, or the measurement result may not meet the entry conditions within the continuous trigger time, or for an event configured with the number of triggering cells, the number of cells in the triggering cell list does not exceed the configured threshold for the number of triggering cells.

[0136] Therefore, the present disclosure provides a method for determining a comparison result between a first distance and a second distance when an entry condition related to a height threshold of a first measurement event is met and a preset trigger condition is met, so that in the above case, it can be determined based on the comparison result whether to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0137] S102: Determine, based on the comparison result, whether to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0138] In some embodiments, the terminal may further determine whether to perform at least one of the following:

[0139] determining whether to apply measurement report configuration information corresponding to the first measurement identifier of the first measurement event;

[0140] determining whether to send a measurement report corresponding to a first measurement identifier associated with the first measurement event;

[0141] determining whether to set an entry of the first measurement identifier in the first measurement report list;

[0142] determining whether to add the first cell to a triggering cell list of the first measurement event;

[0143] determining whether to delete an entry of a measurement identifier corresponding to the second measurement identifier included in the first measurement report list;

[0144] If the second triggered cell list defined for the second measurement identifier in the first measurement report list includes information of the first cell, determining whether to delete the information of the first cell included in the second triggered cell list defined for the second measurement identifier in the first measurement report list;

[0145] If the measurement report configuration information of the second measurement event configures a periodic reporting configuration, and the periodic reporting timer of the second measurement event is running, it is determined whether to stop the periodic reporting timer.

[0146] In some embodiments, when the first distance is less than or equal to the second distance, it is determined to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0147] Exemplarily, when the first distance is less than or equal to the second distance, the terminal may determine to apply measurement report configuration information corresponding to the first measurement identifier used to indicate the first measurement event; and / or determine to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0148] In some embodiments, it may also be determined whether the second measurement event occurs. If the second measurement event does not occur, or the first distance is less than or equal to the second distance, the terminal may determine to apply measurement report configuration information corresponding to the first measurement identifier used to indicate the first measurement event; and / or determine to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0149] In some embodiments, if there is a second measurement event and the first distance is less than or equal to the second distance, the terminal may delete the table entry of the measurement identifier corresponding to the second measurement identifier included in the first measurement report list; or, if the second trigger cell list defined for the second measurement identifier in the first measurement report list contains information about the first cell, the terminal may delete the information of the first cell contained in the second trigger cell list defined for the second measurement identifier in the first measurement report list; or, if the measurement report configuration information of the second measurement event is configured with a periodic reporting configuration and the periodic reporting timer of the second measurement event is running, the terminal may stop the periodic reporting timer.

[0150] In some embodiments, when the first distance is greater than the second distance, it is determined not to send the measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0151] In some embodiments, it may also be determined whether the second measurement event exists. If the second measurement event exists and the first distance is greater than the second distance, the terminal may determine not to apply the measurement report configuration information corresponding to the first measurement identifier of the first measurement event, or not to send the measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0152] It should be understood that at this time, the first measurement event and the first measurement identifier are events and measurement identifiers that meet the measurement report triggering condition, but may not send a measurement report, and the first cell may be a cell for which no measurement report is sent.

[0153] In some embodiments, when the first distance is greater than the second distance and the first measurement report list does not include an entry corresponding to the first measurement identifier, the first measurement report list may further include an entry corresponding to the first measurement identifier.

[0154] Exemplarily, the first measurement report list does not include an entry for the first measurement identifier, and the first measurement report list may include an entry for the first measurement identifier.

[0155] In some embodiments, when the first distance is greater than the second distance and the first measurement report list contains a table entry corresponding to the first measurement identifier, the first cell can also be added to the first trigger cell list defined for the first measurement identifier in the first measurement report list.

[0156] In some embodiments, the terminal may further mark the first measurement identifier as “no measurement report is sent corresponding to the measurement identifier” or “equivalent to sending a measurement report”, or similar marks.

[0157] Alternatively, when the first measurement report list does not include an entry corresponding to the first measurement identifier, the entry corresponding to the first measurement identifier may not be set in the first measurement report list.

[0158] When the first measurement report list includes an entry corresponding to the first measurement identifier, the first cell may not be added to the first triggering cell list defined for the first measurement identifier in the first measurement report list.

[0159] Alternatively, when the first measurement report list includes a table entry corresponding to the first measurement identifier, the terminal may delete the table entry of the measurement identifier corresponding to the first measurement identifier included in the first measurement report list; or, if the measurement report configuration information of the first measurement event is configured with a periodic reporting configuration, and the periodic reporting timer of the first measurement event is running, the terminal may stop the periodic reporting timer.

[0160] In some embodiments, it is determined that the second measurement event occurs, and that a second cell exists that satisfies the following conditions: for all / any second measurement events, the second cell is not included in the second triggering cell list corresponding to the second measurement event, and the second cell is a cell included in the first triggering cell list corresponding to the first measurement event, or the first cell that triggers the first measurement event, then, if the first distance is greater than, equal to, or less than the second distance, at least one of the following is performed:

[0161] determining measurement report configuration information corresponding to a first measurement identifier of the first measurement event;

[0162] Determining to send a measurement report corresponding to a first measurement identifier associated with a first measurement event;

[0163] Determine an entry in the first measurement report list for setting the first measurement identifier;

[0164] Determine to add the first cell to a first triggering cell list of a first measurement event.

[0165] If the second event occurs and the first distance is greater than or equal to the second distance, the terminal includes only the measurement result information of the second cell in the measurement report sent for the first measurement identifier.

[0166] That is, when there is a second event that is closer, the terminal can send a measurement report for a cell that is not included in the triggering cell list of the second event. This ensures that the network can obtain measurement information of cells that have not sent measurement reports.

[0167] It should be noted that the technical solution provided by the present disclosure also provides a cell-based comparison condition, that is, when a new event (first measurement event) is triggered, the triggering cell list of its comparison object (that is, the second measurement cell) also includes the cell that triggered the new event (that is, both events meet the entry conditions in the same cell). This allows for more detailed comparison and avoids comparison between measurement events that meet the entry conditions in different cells. This also avoids the situation where measurement events that meet the entry conditions in different cells do not send measurement reports for them due to the result of distance comparison. In this way, a more detailed control mechanism can be provided for the network.

[0168] In some embodiments, when the first distance is greater than the second distance, a first measurement event or a first measurement identifier may be added to a second measurement report list, which is used to record measurement events or measurement identifiers corresponding to unsent measurement reports. In some embodiments, the second list also includes information about the first cell. Furthermore, the terminal may establish and maintain the second list in local memory or storage.

[0169] It should be noted that, taking the scenario shown in Figure 3 above as an example, when the terminal's altitude simultaneously meets the entry conditions associated with H1 threshold-1 and H1 threshold-2, and when the entry conditions associated with A4 threshold-1 and A4 threshold-2 are simultaneously met, the terminal may simultaneously trigger measurement reports for both measurement identifiers measId-1 and measId-2. In this case, when triggering the measurement report for a measId, the terminal generates an RRC message for the triggered measId to send the measurement result for that measId. This requires sending two different RRC messages for measId-1 and measId-2 to report the measurement reports. However, for practical purposes, these two measurement reports are not necessary, as this clearly wastes radio resources on the radio interface. Alternatively, when the terminal receives an RRC message containing the configurations for measId-1 and measId-2, it evaluates the relationship between the terminal's current altitude and H1 threshold-1 and H1 threshold-2. If the terminal's current altitude is higher than both H1 threshold-1 and H1 threshold-2, the terminal triggers two measurement reports simultaneously. Alternatively, when the current height of the terminal meets the entry conditions related to the above-mentioned H1 threshold-1 and H1 threshold-2, the terminal will trigger two measurement reports at the same time. At time 1, the measurement result of cell 1 meets the entry conditions related to the A4 threshold-1, and the terminal triggers measurement report 1 for measId-1. At time 2, the measurement results of the same cell 1 or different cells 2 meet the entry conditions related to the A4 threshold-2, and the terminal triggers measurement report 2 for measId-2. At time 3, the measurement results of cell 2 or cell 3 meet the entry conditions related to the A4 threshold-1, and the terminal triggers measurement report 3 for measId-1. In this scenario, measId-1 and measId-2 are triggered for measurement reports at different times. From the network's perspective, after measId-2 has triggered the measurement report, the measurement report triggered by measId-1 is not needed.

[0170] In addition, the network configures multiple measurement events to use different measurement configurations at different altitudes. At one altitude, the terminal applies two different measurement configurations and triggers measurement reports for each, making it impossible to implement the requirement of using different measurement configurations at different altitudes.

[0171] Therefore, when the network configures multiple measurement events with height thresholds for the terminal, when the height of the terminal changes, multiple measurement events may be triggered to trigger measurement reports simultaneously or successively. Through the method provided by this embodiment, when the measurement report triggering condition of a new measurement event is met, the terminal determines whether to send a measurement report for the newly triggered measurement event by checking whether there is a measurement event with a height closer to the terminal than the height threshold of the new measurement event that has triggered a measurement report. That is, the application of the distance comparison method can be extended from only simultaneously triggered events to measurement events that have been triggered and are still active (the measurement identifier associated with the measurement event is included in the measurement report list).

[0172] Based on the technical solution provided by the present disclosure, when multiple measurement events may be triggered simultaneously or successively to trigger multiple measurement reports, the distance between the terminal and the height threshold of the previously triggered measurement event and the height threshold of the currently triggered measurement event can be compared, and based on the comparison result, it is determined whether to send a measurement report for the newly triggered measurement event. In this way, it is possible to avoid directly reporting multiple measurement reports corresponding to all triggering events for height, and avoid the waste of wireless resources caused by reporting unnecessary measurement reports. In addition, before sending the measurement report, the terminal distance can be compared with the measurement event that has been triggered, thereby improving the accuracy of the measurement report transmission method and providing a more detailed control mechanism for the network.

[0173] In some embodiments, the present disclosure further provides another method for sending a measurement report, which is applied to a terminal and includes:

[0174] If an exit condition of the first measurement event is met, it is determined whether to send a measurement report corresponding to a first measurement identifier associated with the first measurement event.

[0175] Exemplarily, the first measurement event may be configured with a report on leave. Alternatively, the measurement report triggering condition for the first measurement event is met, but the terminal does not send a measurement report for the first measurement identifier associated with the first measurement event according to the method shown in S101-S102 above. In addition, the first measurement report list may include an entry for the first measurement identifier related to the first measurement event, or the second list may include an entry for the first measurement identifier.

[0176] The exit condition of the first measurement event includes: an exit condition related to a height threshold of the first measurement event, and / or an exit condition related to a first threshold of the first measurement event (or referred to as a threshold related to radio signal measurement).

[0177] Exemplarily, at this time, all measurement results of the first cell that have passed layer 3 filtering meet the exit condition of the first event within the triggering time, or the exit condition related to the height threshold of the first event is met.

[0178] In some embodiments, a measurement report is sent if the leave condition is met.

[0179] In some embodiments, a measurement report corresponding to the first measurement identifier associated with the first measurement event is sent when any one of the following conditions is met:

[0180] The departure condition associated with the altitude threshold of the first measurement event is met;

[0181] In case the first measurement event is configured with the first threshold value, the exit condition of the first measurement event related to the height threshold value is satisfied and the exit condition of the first measurement event related to the first threshold value is also satisfied.

[0182] It should be noted that, in combination with the conditions provided above, a measurement report is only sent when all of the above-mentioned departure conditions are met. A measurement report is not sent when only one of the departure conditions of the first measurement event is met. For example, when the first measurement event is configured with an altitude threshold and a first threshold, the departure conditions of the first measurement event include both departure conditions related to the altitude threshold and departure conditions related to the first threshold. If only the departure condition related to the first threshold is met but the departure condition related to the altitude threshold is not met, in accordance with the above-mentioned requirement of "meeting the departure condition related to the altitude threshold of the first measurement event," the corresponding measurement report is not sent.

[0183] In some embodiments, it may also be determined whether a second measurement event exists. If the second measurement event exists, the first distance and the second distance are obtained, and a comparison result between the first distance and the second distance is determined. Furthermore, based on the comparison result, it is determined whether to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0184] In one embodiment, the exit condition related to the height threshold of the first measurement event is met, and the terminal triggers a measurement report corresponding to the first measurement identifier. It should be noted that the height of the terminal has changed at this time, and the height of the terminal may be lower than the height threshold of the first measurement event. Therefore, although the terminal did not send a measurement report for the first measurement identifier when the entry condition was met, the measurement report when the exit condition is met at this time helps the network obtain changes in the height information of the terminal.

[0185] In another embodiment, if the exit condition of the first measurement event is met, and there is a second measurement event, and the second distance is less than the first distance, etc., it is still possible to send a measurement report based on the second measurement event, and the terminal's altitude still meets the altitude threshold of the second event. In this case, the terminal may choose not to send a corresponding measurement report for the first measurement identifier. Otherwise, if the second event does not exist or the second distance is greater than the first distance, the terminal sends a measurement report corresponding to the first measurement identifier.

[0186] In some embodiments, the network side network element may indicate, through a system message or an RRC message, whether the terminal needs to judge the above conditions to decide whether to send a measurement report.

[0187] In some embodiments, when the terminal determines to send a measurement report corresponding to the first measurement identifier associated with the first measurement event, the reason for triggering the measurement report may also be indicated in the measurement report, for example, an exit condition related to the height threshold of the first measurement event is met, and / or an exit condition related to the first threshold of the first measurement event is met. For another example, when a second measurement event occurs, a comparison result between the first distance and the second distance may also be indicated in the measurement report.

[0188] Based on the technical solution provided in this embodiment, it is possible to determine whether to trigger a measurement report for a measurement event (e.g., a first measurement event) for which a trigger condition is met but for which no measurement report has been sent, when the exit condition is met. Based on this solution, even if the exit condition of the measurement event is met, a measurement report can still be sent for it to report measurement data such as altitude data related to the measurement event. This helps provide more detailed and accurate terminal measurement data, thereby supporting network planning, design, optimization, and maintenance.

[0189] In some embodiments, when the exit condition of the second measurement event is met, the terminal may further perform at least one of the following operations:

[0190] When an entry condition of the first measurement event is met, sending a measurement report corresponding to the first measurement identifier associated with the first measurement event;

[0191] If a cell in the first triggering cell list corresponding to the first measurement identifier does not meet the entry condition of the first measurement event within a preset trigger time, remove the cell from the first triggering cell list;

[0192] sending a measurement report corresponding to a first measurement identifier associated with the first measurement event when an entry condition related to a height threshold of the first measurement event is met;

[0193] If a cell in the first triggering cell list corresponding to the first measurement identifier meets the entry condition of the first measurement event within a preset trigger time, and the first measurement event is configured with the number information of the triggering cells, sending a measurement report corresponding to the first measurement identifier associated with the first measurement event;

[0194] When the first measurement event is configured with information about the number of triggered cells and the number of cells in the first triggering cell list of the first measurement identifier is greater than or equal to the number of triggered cells configured for the first measurement event, sending a measurement report corresponding to the first measurement identifier associated with the first measurement event;

[0195] When a periodic reporting condition is configured for the first measurement event, and when the periodic reporting condition is met, a measurement report corresponding to the first measurement identifier associated with the first measurement event is sent.

[0196] Exemplarily, at this time, the measurement report triggering condition for the first event has been met, but the terminal does not send a measurement report corresponding to the first measurement identifier associated with the first measurement event according to the method shown in S101-S102 above. In addition, the first measurement report list may include an entry for the first measurement identifier related to the first measurement event, or the second list may include an entry for the first measurement identifier. And / or, a second measurement event exists, and the second distance is less than the first distance.

[0197] Furthermore, at this time, all measurement results of the first cell that have passed layer 3 filtering meet the exit condition of the first event within the triggering time, or the exit condition related to the height threshold of the first event is met.

[0198] In some embodiments, at this time, the terminal may also determine whether to send a measurement report corresponding to the first measurement identifier associated with the first measurement event according to the method shown in S101-S102 above, which will not be described in detail here.

[0199] The technical solution provided in this embodiment can be applied to measurement events in which the triggering conditions of a measurement event are met, but the corresponding measurement report is not sent due to the existence of another measurement event at a closer distance. When the entry conditions of the other event are no longer met, or the conditions for sending a measurement report of the other event are no longer met, the terminal can again detect those events that previously met the triggering conditions but did not send a measurement report, and determine whether the corresponding measurement report can be sent. In other words, when the triggering conditions / entry conditions of the previous measurement events at a closer distance are no longer met, the terminal can detect the measurement events that were blocked by these measurement events at a closer distance to determine whether to trigger the corresponding measurement report.

[0200] In some embodiments, a measurement reporting configuration may be configured for a terminal, and the measurement reporting configuration may include a "single reporting upon simultaneous triggering" configuration. The single reporting upon simultaneous triggering configuration is included in an information element in the measurement reporting configuration. The information element is an integer value, the number of which may be greater than or equal to 1. For example, the value of the single reporting upon simultaneous triggering configured for measurement reporting configuration-1 may be n1, and the value of the single reporting upon simultaneous triggering configured for measurement reporting configuration-2 may be n2.

[0201] In some embodiments, the terminal may perform measurement reporting according to a value of a single report when simultaneously triggered configured in a measurement reporting configuration associated with a measurement identifier.

[0202] Exemplarily, the terminal may compare measurement events associated with measurement reporting configurations having the same single reporting value when triggered simultaneously, and determine, based on the comparison result, whether to perform at least one of the following operations:

[0203] Apply one of the above measurement reporting configurations;

[0204] sending a measurement report for the above-mentioned one measurement identifier;

[0205] An entry of the measurement identifier is configured in a measurement report list. For example, in NR, the measurement report list is VarMeasReportList.

[0206] In some embodiments, the terminal implements any of the above methods of this document for measurement events with the same single reported value when triggered simultaneously, that is, the first event and the second event are configured with the same single reported value when triggered simultaneously.

[0207] For example, in an NR system, the MultiTriggerSingleMeasReport information element is used to configure a single report when triggering simultaneously. The value of this information element is an integer. Different measurement events can be configured with different MultiTriggerSingleMeasReport values, or they can be configured with the same MultiTriggerSingleMeasReport value. For example, the MultiTriggerSingleMeasReport value configured for events 1 and 2 is 1, and the MultiTriggerSingleMeasReport value configured for events 3 and 4 is 2.

[0208] By configuring different MultiTriggerSingleMeasReport values, the network can group multiple measurement events into different groups and perform a "single report when triggered simultaneously" comparison between measurement events in the same group. For example, compare event 1 with event 2, and event 3 with event 4.

[0209] In this way, a more refined grouping method for comparison between control events can be provided to the network. For events associated with the same measurement object and with the same measurement event type, different events can also be grouped and compared using this method. For example, events configured with numberOfTriggeringCells are grouped together, and events not configured with numberOfTriggeringCells are grouped together. The distances (between the event's height threshold and the UE's height) are compared between events in the same group, and no distance comparison is performed between events in different groups.

[0210] The above mainly introduces the solution provided by the present disclosure from the perspective of the interaction between various communication nodes. It is understandable that, in order to implement the above functions, each communication node includes a hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present disclosure.

[0211] FIG4 is a schematic diagram showing the composition of a communication device provided by an embodiment of the present disclosure. As shown in FIG4 , the communication device 40 includes a first determination module 401 , a second determination module 402 , and a processing module 403 .

[0212] The first determination module 401 is used to determine a comparison result between a first distance and a second distance when an entry condition related to a height threshold of a first measurement event is met; the first distance is the distance between the height threshold of the first measurement event and the height of the terminal; the second distance is the distance between the height threshold of the second measurement event and the height of the terminal.

[0213] The second determining module 402 is configured to determine, based on the comparison result, whether to send a measurement report corresponding to the first measurement identifier associated with the first measurement event.

[0234] In some embodiments, the first cell is a cell that triggers the first measurement event, or the first cell is a cell in a second triggered cell list defined for the second measurement identifier in the first measurement report list.

[0235] In some embodiments, the second determination module 402 is used to: determine to send a measurement report corresponding to the first measurement identifier associated with the first measurement event when the first distance is less than or equal to the second distance; or, determine not to send a measurement report corresponding to the first measurement identifier associated with the first measurement event when the first distance is greater than the second distance.

[0236] In some embodiments, the processing module 403 is configured to set an entry corresponding to the first measurement identifier in the first measurement report list if the first measurement report list does not include an entry corresponding to the first measurement identifier.

[0237] In some embodiments, when the first distance is greater than the second distance, the processing module 403 is further used to add the first cell to the first trigger cell list defined for the first measurement identifier in the first measurement report list when the first measurement report list includes a table entry corresponding to the first measurement identifier.
