[0021] Embodiments of this disclosure propose trigger determination, indication methods and apparatus, terminals, network devices, and storage media.

[0022] In a first aspect, embodiments of this disclosure propose a trigger determination method executed by a terminal, the method comprising: determining a quantity threshold according to a predefined rule or a first indication information of a network device; measuring at least one beam, determining a first beam that satisfies a measurement event, and determining a first quantity of relevant information of the first beam; and triggering the reporting of the measurement result of the first beam when the relationship between the first quantity and the quantity threshold satisfies a first relationship.

[0023] In the above embodiments, the terminal can trigger the reporting of the measurement results of the first beam only when the first quantity and the quantity threshold satisfy the first relationship. For example, if the first quantity and the quantity threshold do not satisfy the first relationship, the reporting of the measurement results of the first beam will not be triggered. Accordingly, when the relevant information of the beam that satisfies the measurement event is relatively small, the reporting of the measurement results will not be triggered, which helps to avoid excessive signaling overhead caused by frequent reporting of measurement results.

[0024] In conjunction with some embodiments of the first aspect, in some embodiments, the quantity threshold is applicable to reporting triggered by all measurement events; or, the quantity threshold is applicable to reporting triggered by a specific measurement event.

[0025] In conjunction with some embodiments of the first aspect, in some embodiments, when the quantity threshold applies to reporting triggered by all measurement events, the first quantity is the number of measurement results satisfying any one type of measurement event; or, when the quantity threshold applies to reporting triggered by a specific measurement event, the first quantity is the number of measurement results satisfying the specific measurement event.

For example, if the second number and the number threshold do not satisfy the first relationship, the reporting of the measurement results of the second beam will not be triggered.

For example, if the third number and the number threshold do not satisfy the first relationship, the reporting of the measurement results of the third number of beams will not be triggered. Accordingly, when the relevant information of the third beam is relatively small, the reporting of measurement results will not be triggered, which helps to avoid excessive signaling overhead caused by frequent reporting of measurement results.

[0099] Event A4H1: Neighbour becomes better than threshold1 and the Aerial UE altitude becomes higher than a threshold2.

[0100] Event A4H2: Neighbour becomes better than threshold1 and the Aerial UE altitude becomes lower than a threshold2.

[0101] Event A5H1: SpCell becomes worse than threshold1, neighbor becomes better than threshold2, and the Aerial UE altitude becomes higher than threshold3.

[0102] Event A5H2: SpCell becomes worse than threshold1, neighbor becomes better than threshold2, and the Aerial UE altitude becomes lower than threshold3.

[0103] In some embodiments, a highly correlated measurement resource configuration may be introduced in RRM (Radio Resource Management) measurements to indicate specific measurement resources within different altitude ranges.

[0104] For example, network devices may deploy dedicated resources (such as upward beams) to provide better coverage for drone terminals.

[0105] In some embodiments, considering that LTM (L1 / L2 Triggered Mobility) can achieve fast and low-latency handover, using LTM for terminals (e.g., drones) can effectively improve the mobility performance of terminals (e.g., drones), reduce handover interruptions, reduce handover latency, and achieve fast and efficient handover.

[0106] LTM refers to the process by which network devices receive L1 measurement reports from terminals. Based on the received L1 measurement results, network devices can send Cell Switch Command signaling to terminals via MAC CE (Media Access Control Control Element) to realize the process of changing the terminal's service cell.

[0107] For example, network devices pre-send multiple LTM candidate configurations to the terminal via RRC (Radio Resource Control) signaling. When LTM is subsequently triggered, a MAC CE is used to indicate the LTM candidate configuration corresponding to the target cell to be accessed. The terminal then applies the corresponding LTM target configuration to complete the serving cell change. Notably, sending a MAC CE based on L1 measurement results to trigger cell handover allows for rapid response to channel changes and timely handover.

[0108] For example, during LTM (Low-Time Measuring) processing, early uplink and downlink synchronization for candidate cells is supported, enabling RACH-less LTM Cell Switching (reducing LTM cell handover via random access channels). For instance, the TA (Timing Advance) values ​​of LTM candidate cells can be obtained in advance through two methods: early TA acquisition and terminal-based TA measurement, to support RACH-less LTM Cell Switching. Performing early uplink and downlink synchronization for candidate cells to achieve RACH-less LTM Cell Switching effectively reduces data interruptions during handover.

[0109] For example, LTM can support Subsequent LTM, where the terminal does not release the LTM candidate configuration after each LTM Cell Switch. This allows the terminal to continue performing subsequent Cell Switches after mobility execution without RRC reconfiguration or reset. Supporting Subsequent LTM can effectively reduce signaling overhead.

[0110] In some embodiments, L1 measurement and measurement reporting may include network-triggered L1 measurement reporting and event-based L1 measurement reporting.

[0111] Regarding network-triggered L1 measurement reporting, L1 measurement has been enhanced in R18 LTM, supporting both intra-frequency and inter-frequency L1 measurements.

[0112] For example, it can support L1-RSRP (Reference Signal Receiving Power) measurement based on SSB (Synchronization Signal Block).

[0113] For example, L1 measurements support semi-persistent and aperiodic reporting on PUSCH (Physical Uplink Shared Channel) and semi-persistent and periodic reporting on PUCCH (Physical Uplink Control Channel).

[0114] Enhancements to support continued L1 measurements in R19 can include the following aspects:

[0115] CSI-RS (Channel State Information Reference Signal) measurement;

[0116] L1-SINR (Signal to Interference plus Noise Ratio) measurement;

[0117] Event-triggered L1 measurement reporting;

[0118] Current L1 measurement is enhanced.

[0119] Regarding event-based L1 measurement reporting, in order to reduce measurement reports and improve mobility robustness, R19 supports event-triggered measurement reporting. Event-triggered measurement reporting can assist the network side in selecting the target beam and / or cell to trigger early synchronization, or assist the network side in selecting the target cell and / or the corresponding beam when triggering LTM Cell Switch.

[0120] A measurement report can be triggered when the measurement result of L1 meets the following event:

[0121] First measurement event (e.g., denoted as Event LTM2): Beam of serving cell becomes worse than absolute threshold;

[0122] The second measurement event (e.g., denoted as Event LTM3): The beam of the candidate cell becomes the amount of offset better than the beam of the serving cell.

[0123] The third measurement event (e.g., denoted as Event LTM4): The beam of candidate cell becomes better than the absolute threshold.

[0124] The fourth measurement event (e.g., denoted as Event LTM5): The beam of the serving cell becomes worse than absolute threshold1 and the beam of the candidate cell becomes better than another absolute threshold2.

[0125] For example, the serving cell's beam is the current beam, which is the beam indicated by the indicated TCI (Transmission Configuration Indicator) state. The candidate cell's beam is any one or more beams configured in the candidate reference signal configuration (or measurement resource configuration).

[0126] For example, event-based L1 measurement reporting is sent to the network via MAC CE messages.

[0127] For example, measurement events are configured in the serving cell configuration, and the configuration of measurement events is associated with the configuration of measurement resources.

[0128] In some embodiments, when measurement and reporting technologies are applied to airborne terminals such as drones, for example, LTM is applied to airborne terminals such as drones, it is beneficial to improve the handover performance of airborne terminals, such as increasing the handover rate, reducing handover latency, and reducing handover signaling overhead.

[0129] However, this situation also presents some technical challenges. Because aerial terminals such as drones have a longer line-of-sight transmission range than ground terminals, they have more neighboring cells compared to the opposite terminal. Furthermore, aerial terminals are more mobile than ground terminals, passing through more cells, which also results in them having more neighboring cells compared to the opposite terminal.

[0130] Since the air terminal has a relatively large number of neighboring cells, the total number of beams in the neighboring cells is also relatively large. This will result in beams that meet measurement events appearing more frequently, thus triggering reporting. However, whenever a new beam meets a measurement event, a report is triggered. The terminal will not only report the measurement results of the new beam, but also report the measurement results of the beams that have already been reported to meet the measurement event. This will lead to frequent reporting and increase signaling overhead.

[0131] Figure 2 is an interactive schematic diagram illustrating a trigger determination method according to an embodiment of the present disclosure.

[0132] In some embodiments, the trigger determination method may be executed by the terminal.

[0133] For example, the terminal may include a traditional terminal (such as a mobile phone or other ground terminal) or an aerial terminal (such as a drone). The following mainly uses a drone as an example to illustrate the technical solution of this disclosure.

[0134] As shown in Figure 2, the trigger determination method may include the following steps:

[0135] In some embodiments, the terminal may determine the quantity threshold based on predefined rules or first indication information from the network device.

[0136] For example, the quantity threshold can be specified by predefined rules (e.g., protocol agreement), or the network device can send a first indication information to the terminal, which is used to indicate the quantity threshold to the terminal.

[0137] In some embodiments, the indication information includes a measurement configuration, which includes a quantity threshold.

[0138] For example, when a network device indicates a quantity threshold to a terminal via indication information, the indication information may include a measurement configuration, and the quantity threshold may be carried in the measurement configuration.

[0139] For example, a measurement configuration may include an L1 measurement configuration, which may include a measurement resource configuration and a measurement reporting configuration. Quantity thresholds can be included in either the measurement resource configuration or the measurement reporting configuration.

[0140] For example, L1 measurement may include at least one of the following: LTM measurement, CSI measurement, L2 measurement, beam measurement, measurement with measurement results reported via UCI (Uplink Control Information), and measurement with measurement results reported via MAC CE.

[0141] For example, measurement resource configuration can be used to configure the resources of the reference signal under test, such as the reference signal under test may include at least one of the following: SSB, CSI-RS.

[0142] For example, measurement reporting configuration can be used to configure reporting criteria (e.g., what measurement events trigger reporting) and related parameters (e.g., thresholds in measurement events).

[0143] For example, the measurement events include at least one of the following:

[0144] The measurement result of the serving cell's beam is less than the first threshold (e.g., denoted as Event LTM2);

[0145] The measurement result of the serving cell's beam is less than or equal to the first threshold (e.g., denoted as Event LTM2);

[0146] The measurement result of the candidate cell's beam is greater than the measurement result of the serving cell's beam by a first offset (e.g., denoted as Event LTM3);

[0147] The measurement result of the candidate cell's beam is greater than or equal to the measurement result of the serving cell's beam by a first offset (e.g., denoted as Event LTM3).

[0148] The beam measurement result of the candidate cell is greater than the second threshold (e.g., denoted as Event LTM4);

[0149] The measurement result of the beam of the candidate cell is greater than or equal to the second threshold (e.g., denoted as Event LTM4);

[0150] The measurement result of the serving cell's beam is less than the first threshold, and the measurement result of the candidate cell's beam is greater than the second threshold (e.g., denoted as Event LTM5).

[0151] The measurement result of the serving cell's beam is less than or equal to a first threshold, and the measurement result of the candidate cell's beam is greater than or equal to a second threshold (e.g., denoted as Event LTM5).

[0152] In step S201, at least one beam is measured to determine a first beam that satisfies the measurement event, and a first quantity of relevant information of the first beam is determined.

[0153] In some embodiments, the terminal can measure at least one beam.

[0154] For example, the beam being measured may include at least one of the following:

[0155] The beam that serves the community;

[0156] Beams from neighboring cells;

[0157] Beams of candidate cells.

[0158] In some embodiments, the terminal may determine the first beam that satisfies the measurement event based on the measurement results obtained from measuring at least one beam.

[0159] For example, determining the first beam that satisfies the measurement event may include at least one of the following:

[0160] A beam that satisfies a single measurement event;

[0161] A beam that satisfies multiple measurement events within a time window;

[0162] The beam that satisfies each measurement event within the time window.

[0163] In some embodiments, the relevant information of the first beam includes at least one of the following:

[0164] First beam;

[0165] The cell where the first beam is located.

[0166] For example, the relevant information of the first beam is the first beam, and the terminal measures at least one beam, so that the number of the first beams that satisfy the measurement event can be determined as the first quantity.

[0167] For example, the relevant information of the first beam is the cell where the first beam is located. The terminal measures at least one beam, which can determine the first beam that meets the measurement event, and then determine the number of cells where the first beam is located as the first number.

[0168] In step S202, if the relationship between the first quantity and the quantity threshold satisfies the first relationship, the measurement results of the first beam are triggered to be reported.

[0169] In some embodiments, after obtaining a first quantity by measuring the beam, the terminal can compare the first quantity with a quantity threshold to determine whether the relationship between the first quantity and the quantity threshold satisfies a first relationship.

[0170] For example, the relevant information for the first beam is the first beam. After the terminal determines the first number of the first beams that satisfy the measurement event, it can compare the first number with a quantity threshold to determine whether the relationship between the first number and the quantity threshold satisfies the first relationship. For example, if the first number of beams that satisfy the measurement event is greater than the quantity threshold, the measurement result of the first beam can be reported.

[0171] For example, the relevant information for the first beam is the cell where the first beam is located. After the terminal determines the first number of cells where the first beam meets the measurement event, it can compare the first number with a quantity threshold to determine whether the relationship between the first number and the quantity threshold satisfies the first relationship. For example, if the first number of cells where the first beam meets the measurement event is greater than the quantity threshold, the measurement result of the first beam can be reported.

[0172] It should be noted that the quantity threshold used for comparison with the first quantity can be different when the relevant information of the first beam is the first beam and when the relevant information of the first beam is the cell where the first beam is located. For example, when the relevant information of the first beam is the first beam, the quantity threshold can be the beam quantity threshold (e.g., denoted as X). When the relevant information of the first beam is the cell where the first beam is located, the quantity threshold can be the cell quantity threshold (e.g., denoted as Y).

[0173] Furthermore, the relevant information of the first beam may only include the first beam, or only include the cell where the first beam is located, or may include both the first beam and the cell where the first beam is located. In the case where the relevant information of the first beam includes both the first beam and the cell where the first beam is located, the terminal triggers the reporting of the measurement results of the first beam when the relationship between the first quantity and the quantity threshold satisfies the first relationship. This can be triggered only when the first beam that satisfies the measurement event satisfies the first relationship with X, and the cell where the first beam satisfies the measurement event satisfies the first relationship with Y.

[0174] For example, a first relation may include at least one of the following:

[0175] The first quantity is greater than the quantity threshold;

[0176] The first quantity equals the quantity threshold;

[0177] The first quantity is less than the quantity threshold.

[0178] The following embodiments mainly use the example of a first relationship including a first quantity greater than a quantity threshold to illustrate the technical solution of this disclosure.

[0179] In some embodiments, the terminal determines whether the relationship between the first quantity and the quantity threshold satisfies the first relationship. The first quantity can be considered statically, for example, the terminal can directly determine whether the obtained first quantity is greater than the quantity threshold; or the first quantity can be considered dynamically, for example, the terminal can record the quantity obtained after the most recent measurement (for example, called the historical quantity), and then compare the historical quantity with the first quantity to determine whether the first quantity has become greater than the quantity threshold relative to the historical quantity (for example, the historical quantity is not greater than the quantity threshold).

[0180] Taking the relevant information of the first beam as an example, if the terminal, after measuring at least one beam, determines that the first beam satisfying the measurement event includes beam#1, beam#2, beam#3, and beam#4, and the first quantity is 4 (for example, if the quantity threshold is 3), then the first quantity is greater than the quantity threshold, satisfying the first relationship, and the measurement results of beam#1, beam#2, beam#3, and beam#4 can be triggered for reporting. However, if it is determined that the first beam satisfying the measurement event includes beam#1 and beam#2, and the first quantity is 2 (for example, if the quantity threshold is 4), then the first quantity is not greater than the quantity threshold, not satisfying the first relationship, and the measurement results of beam#1 and beam#2 will not be triggered for reporting.

[0181] Taking the relevant information of the first beam, including the cell where the first beam is located, as an example, after the terminal measures at least one beam, it determines that the first beam that satisfies the measurement event includes beam#1, beam#2, beam#3, and beam#4. Among them, the cell where beam#1 and beam#2 are located is cell#1, and the cell where beam#3 and beam#4 are located is cell#2. The first quantity is 2. For example, if the quantity threshold is 3, then the first quantity is less than the quantity threshold and does not satisfy the first relationship. Therefore, the measurement results of beam#1, beam#2, beam#3, and beam#4 may not be triggered for reporting.

[0182] Taking the relevant information of the first beam, including the first beam and its cell, as an example, we need to consider the beam number threshold X and the cell number threshold Y in the quantity threshold, for example, X=3, Y=3. After the terminal measures at least one beam, it determines that the first beams that satisfy the measurement event include beam#1, beam#2, beam#3, and beam#4. Among them, beam#1 and beam#2 are located in cell#1, and beam#3 and beam#4 are located in cell#2. It can be determined that the number of first beams that satisfy the measurement event is 4, which is greater than the beam number threshold X. The number of cells where the first beams that satisfy the measurement event are located is 2, which is less than the cell number threshold Y. Therefore, the measurement results of beam#1, beam#2, beam#3, and beam#4 are not triggered for reporting.

[0183] According to embodiments of this disclosure, the terminal may trigger the reporting of the measurement results of the first beam only when the first quantity and the quantity threshold satisfy the first relationship. For example, if the first quantity and the quantity threshold do not satisfy the first relationship, the reporting of the measurement results of the first beam will not be triggered. Accordingly, when the relevant information of the beam that satisfies the measurement event is relatively small, the reporting of the measurement results will not be triggered, which helps to avoid excessive signaling overhead caused by frequent reporting of measurement results.

[0184] In some embodiments, the quantity threshold is applicable to reporting triggered by a specific measurement event.

[0185] For example, when the quantity threshold applies to reporting triggered by a specific measurement event, the first quantity is the number of measurement results that satisfy the specific measurement event.

[0186] The terminal measures at least one beam and determines a first number of relevant information for a first beam that satisfies a measurement event, which may be determining a first number of relevant information for a first beam that satisfies a specific measurement event.

[0187] For example, a specific measurement event can be one or more measurement events. Taking Event LTM2 as an example, the terminal can determine a first number of relevant information for the first beam that satisfies Event LTM2. For example, the first beam that satisfies the specific measurement event can be recorded in the trigger beam list. If the number of beams in the trigger beam list is greater than a threshold, the measurement result of the first beam can be triggered for reporting.

[0188] It should be noted that the terminal can perform beam measurements based on measurement resources (or sets of measurement resources). Different beams can correspond to different measurement resources (or sets of measurement resources), and different measurement resources (or sets of measurement resources) can correspond to different identifiers (e.g., IDs). For example, the identifier of a measurement resource set can be an LTM CSI resource set ID. Beams in a measurement resource (or set of measurement resources) can come from different cells (e.g., serving cell, neighboring cells, candidate cells).

[0189] In some embodiments, the quantity threshold applies to reporting triggered by all measurement events.

[0190] For example, if the quantity threshold applies to reporting triggered by all measurement events, the first quantity is the number of measurement results that satisfy any one type of measurement event.

[0191] For example, all measurement events can be predefined, such as Event LTM2, Event LTM3, Event LTM4, and Event LTM5, or all measurement events can be configured by the network device, such as Event LTM2, Event LTM3, and Event LTM4.

[0192] The terminal measures at least one beam and determines a first quantity of relevant information for a first beam that satisfies a measurement event. This first quantity can be obtained by determining the quantity of relevant information for the first beam that satisfies each measurement event for each measurement time, and then summing the quantities determined for each measurement event. For example, a measurement report can be generated based on the measurement results corresponding to each measurement event and reported to the network device.

[0193] In some embodiments, at least one beam is measured again to determine a second beam outside the first beam that satisfies the measurement event, and a second quantity of relevant information of the second beam is determined; then, if a first relationship is satisfied between the second quantity and a quantity threshold, the measurement result of the second beam is triggered to be reported.

[0194] For example, after measuring at least one beam, the terminal can record relevant information about the first beam that satisfies the measurement event. After the terminal measures at least one beam again (which may be the same as or different from the beam measured previously), it can identify a second beam other than the first beam that satisfies the measurement event, determine a second quantity of relevant information about the second beam, and then compare the second quantity with a quantity threshold to determine whether a first relationship is satisfied between the second quantity and the quantity threshold.

[0195] In some embodiments, the relevant information of the second beam includes at least one of the following:

[0196] Second beam;

[0197] The cell where the second beam is located.

[0198] The application of information related to the second beam is similar to that of the first beam, and will not be repeated here.

[0199] Taking the information related to the second beam as an example, after measuring at least one beam, the terminal determines that the first beams satisfying the measurement event include beam#1, beam#2, and beam#3. When measuring at least one beam again, it determines that the beams satisfying the measurement event include beam#1, beam#3, beam#4, beam#5, and beam#6. Among them, beam#4, beam#5, and beam#6 are second beams that satisfy the measurement event, other than the first beams, and the second quantity is 3. For example, if the quantity threshold is 2, the second quantity is greater than the quantity threshold, thus satisfying the first relationship, which can trigger the reporting of the measurement results of beam#4, beam#5, and beam#6.

[0200] Taking the information related to the second beam, including the cell where the second beam is located, as an example, after the terminal measures at least one beam, it determines that the first beams satisfying the measurement event include beam#1, beam#2, and beam#3. When at least one beam is measured again, it determines that the beams satisfying the measurement event include beam#1, beam#3, beam#4, beam#5, and beam#6. Among them, beam#4, beam#5, and beam#6 are second beams that satisfy the measurement event, other than the first beams. For example, the cell where beam#4 is located is cell#4, the cell where beam#5 is located is cell#5, and the cell where beam#6 is located is cell#6, and the second quantity is 3. For example, if the quantity threshold is 2, the second quantity is greater than the quantity threshold, thus satisfying the first relationship, thereby triggering the reporting of the measurement results of beam#4, beam#5, and beam#6.

[0201] Taking the information related to the second beam, including the second beam and its cell, as an example, the beam number threshold X and cell number threshold Y in the quantity threshold need to be considered separately. For example, X = 2, Y = 2. After the terminal measures at least one beam, it determines that the beams that satisfy the measurement event include beam#1, beam#2, and beam#3. When at least one beam is measured again, it determines that the beams that satisfy the measurement event include beam#1, beam#3, beam#4, beam#5, and beam#6. Among them, beam#4, beam#5, and beam#6 are second beams that satisfy the measurement event, other than the first beam. For example, the cell where beam#4 is located is cell#4, the cell where beam#5 is located is cell#5, and the cell where beam#6 is located is cell#6. Then it can be determined that the number of second beams is 3, which is greater than the beam number threshold X, and the number of cells where the second beam is located is 3, which is greater than the cell number threshold Y. Therefore, the measurement results of beam#4, beam#5, and beam#6 can be triggered for reporting.

[0202] In this embodiment, the terminal can trigger the reporting of the measurement results of the second number of beams only when the second number and the number threshold satisfy the first relationship. For example, if the second number and the number threshold do not satisfy the first relationship, the reporting of the measurement results of the second beam will not be triggered. Accordingly, when the relevant information of the second beam is relatively small, the reporting of the measurement results will not be triggered, which helps to avoid excessive signaling overhead caused by frequent reporting of measurement results.

[0203] In some embodiments, the terminal can determine the third beam corresponding to the unreported measurement results in the measurement results of the first beam, determine the third quantity of relevant information of the third beam, and trigger the reporting of the measurement results of the third beam if the third quantity satisfies the first relationship with the quantity threshold.

[0204] For various reasons, some beam measurement results were not reported. For example, the terminal did not send the beam measurement results to the network device, or the terminal sent the beam measurement results to the network device, but the network device failed to successfully receive the beam measurement results.

[0205] For example, one reason why a terminal may not send beam measurement results to the network device could be that the information available for carrying the measurement results is full. For instance, the terminal might carry measurement results via a MAC CE, but due to the size priority of the MAC CE, a single MAC CE cannot carry the measurement results for every beam. Therefore, it can only carry and report the measurement results for a portion of the beams in the MAC CE, while the remaining measurement results are considered unreported.

[0206] When the terminal triggers the reporting of measurement results again, it can prioritize carrying the measurement results of the second number of beams in the previous embodiment through the MAC CE (e.g., the first uplink grant (UL grant) corresponding to the MAC CE), or prioritize carrying the measurement results of the third number of beams in this embodiment.

[0207] For example, after measuring at least one beam, the terminal can record the relevant information of the first beam that satisfies the measurement event. After reporting the measurement results, the terminal can record the third quantity of the relevant information of the third beam that was not reported. Then, the third quantity is compared with the quantity threshold to determine whether the third quantity and the quantity threshold satisfy the first relationship.

[0208] In some embodiments, the relevant information for the third beam includes at least one of the following:

[0209] Third beam;

[0210] The cell where the third beam is located.

[0211] The application of information related to the third beam is similar to that of the first beam, and will not be repeated here.

[0212] Taking the information related to the third beam as an example, after the terminal measures at least one beam, it determines that the first beams satisfying the measurement event include beam#1, beam#2, beam#3, beam#4, beam#5, and beam#6. Due to the limited size of the MAC CE, the terminal only reports the measurement results of beam#1, beam#2, and beam#3 to the network device through a single MAC CE. Therefore, the third beams corresponding to the unreported measurement results are beam#4, beam#5, and beam#6, meaning the third quantity is 3. For example, if the quantity threshold is 2, the third quantity is greater than the threshold, thus satisfying the first relationship and triggering the reporting of the measurement results of beam#4, beam#5, and beam#6.

[0213] Taking the information related to the third beam, including the cell where the beam is located, as an example, after the terminal measures at least one beam, it determines that the first beams satisfying the measurement event include beam#1, beam#2, beam#3, beam#4, beam#5, and beam#6. Due to the limited size of the MAC CE, the terminal only reports the measurement results of beam#1, beam#2, and beam#3 to the network device through a single MAC CE. Therefore, the third beams corresponding to the unreported measurement results are beam#4, beam#5, and beam#6. Among them, beam#4 is located in cell#4, beam#5 in cell#5, and beam#6 in cell#6, meaning the third quantity is 3. For example, if the quantity threshold is 2, the third quantity is greater than the quantity threshold, thus satisfying the first relationship, which triggers the reporting of the measurement results of beam#4, beam#5, and beam#6.

[0214] Taking the information related to the third beam, including the beam and its cell, as an example, we need to consider the beam number threshold X and cell number threshold Y in the quantity threshold, for example, X=2, Y=2. After measuring at least one beam, the terminal determines that the first beams that satisfy the measurement event include beam#1, beam#2, beam#3, beam#4, beam#5, and beam#6. Since the MAC CE has a limited size, the terminal only reports the measurement results of beam#1, beam#2, and beam#3 to the network device through a single MAC CE. The third beams corresponding to the unreported measurement results are beam#4, beam#5, and beam#6. Among them, beam#4 is located in cell#4, beam#5 is located in cell#5, and beam#6 is located in cell#6. Therefore, it can be determined that the number of third beams is 3, which is greater than the beam number threshold X, and the number of cells where the third beams are located is 3, which is greater than the cell number threshold Y. Therefore, the reporting of the measurement results of beam#4, beam#5, and beam#6 can be triggered.

[0215] In this embodiment, the terminal can trigger the reporting of the measurement results of the third number of beams only when the third number and the number threshold satisfy the first relationship. For example, if the third number and the number threshold do not satisfy the first relationship, the reporting of the measurement results of the third number of beams will not be triggered. Accordingly, when the relevant information of the third beam is relatively small, the reporting of measurement results will not be triggered, which helps to avoid excessive signaling overhead caused by frequent reporting of measurement results.

[0216] In some embodiments, the terminal may determine (e.g., based on predefined rules or second indication information from the network device) that if the first beam meets the departure condition, it may trigger the reporting of the first measurement result of the first beam; if it is determined that the first measurement result has been reported, it may trigger the reporting of the first measurement result if the first beam meets the departure condition.

[0217] For example, predefined rules can stipulate, or network devices can instruct, via second indication information to the terminal, that if the first beam meets the departure condition, the first measurement result of the first beam should be reported.

[0218] In this scenario, the terminal can trigger the reporting of the first measurement result of the first beam only if the first beam has already reported its measurement result and the departure condition is met; otherwise, if the first measurement result of the first beam has not been reported, the terminal will not trigger the reporting of the first measurement result of the first beam if the departure condition is met.

[0219] For example, the departure condition for the first beam can include at least one of the following:

[0220] The first beam satisfies the departure condition for a measurement event;

[0221] The first beam satisfies the departure condition of multiple measurement events within the time window;

[0222] The first beam satisfies the departure condition for each measurement event within the time window.

[0223] This disclosure does not limit the specific departure conditions, for example, they can correspond to Event LTM2, Event LTM3, Event LTM4, and Event LTM5 in the previous embodiments.

[0224] In some embodiments, when a terminal determines that a first measurement result has been reported, triggering the reporting of the first measurement result when the first beam meets the departure condition may include:

[0225] Once the terminal confirms that the first measurement result has been reported, and the first beam meets the departure condition, and the relationship between the relevant information of the first beam and the quantity threshold satisfies the first relationship, the terminal triggers the reporting of the first measurement result.

[0226] For example, if the first measurement result has been reported and the first beam meets the departure condition, the terminal can also determine whether the relationship between the number of the first beam or the number of cells where the first beam is located and the number threshold satisfies the first relationship. If the first relationship is satisfied, the first measurement result will be reported. If the first relationship is not satisfied, the first measurement result will not be reported.

[0227] Take, for example, determining whether the relationship between the number of the first beams and the number threshold satisfies the first relationship. For instance, if the first beams include beam#1, beam#2, and beam#3, and the measurement results of these three beams have been reported, the terminal can determine that the number of the first beams is 3. If the number threshold is 2, the number of the first beams is greater than the number threshold, thus satisfying the first relationship. This triggers the reporting of measurement results for beam#1, beam#2, and beam#3 that meet the departure condition.

[0228] Taking the determination of whether the relationship between the number of cells containing the first beam and the number threshold satisfies the first relationship as an example. For example, the first beam includes beam#1, beam#2, and beam#3, and the measurement results of these three beams have been reported. Among them, the cell containing beam#1 is cell#1, the cell containing beam#2 is cell#2, and the cell containing beam#3 is cell#3. It can be determined that the number of cells containing the first beam is 3. For example, if the number threshold is 2, the number of cells containing the first beam is greater than the number threshold, so the first relationship is satisfied, and the reporting of the measurement results of beam#1, beam#2, and beam#3 meeting the departure condition can be triggered.

[0229] Taking the determination of whether the relationship between the number of the first beam and the number of cells containing the first beam and the number threshold satisfies the first relationship as an example, it is necessary to determine whether the relationship between the number of the first beam and the beam number threshold X satisfies the first relationship, and whether the relationship between the number of cells containing the first beam and the cell number threshold Y satisfies the first relationship, for example, X=2, Y=2. For example, the first beam includes beam#1, beam#2, and beam#3, and the measurement results of these three beams have been reported. Among them, the cell containing beam#1 is cell#1, the cell containing beam#2 is cell#2, and the cell containing beam#3 is cell#3. It can be determined that the number of the first beam is 3, and the number of cells containing the first beam is 3. The number of the first beam is greater than X, and the number of cells containing the first beam is greater than Y, both satisfying the first relationship. Therefore, the reporting of the measurement results of beam#1, beam#2, and beam#3 that meet the departure condition can be triggered.

[0230] In some embodiments, the terminal determines the quantity threshold based on predefined rules or first indication information from the network device, which may include:

[0231] Determine (e.g., based on predefined rules or first indication information of network devices) the correlation between terminal height and quantity thresholds; determine the quantity threshold corresponding to terminal height based on the correlation.

[0232] For example, predefined rules can specify association relationships, or network devices can indicate association relationships to terminals through first indication information. Here, the association relationship is the relationship between the terminal's height and a certain number threshold.

[0233] For example, in the case where the terminal includes a drone, since the drone's altitude is related to the number of beams that can be measured, different quantity thresholds can be determined for different altitudes to be applicable to measurement reporting at the terminal's current altitude.

[0234] For example, in association relationships, height can be positively correlated with a quantity threshold, or height can be negatively correlated with a quantity threshold.

[0235] For example, in a relationship, the height associated with a quantity threshold can be a height value or a height range.

[0236] For example, taking the height related to the quantity threshold in the association relationship as an example, each height range can include an upper height limit (altitudeMax) and a lower height limit (altitudeMin). For example, when the terminal's height is in height range #1 (altitudeMin#1 to altitudeMax#1), ​​the terminal can determine the quantity threshold as the quantity threshold #1 corresponding to height range #1, and thus perform the steps in the previous embodiment based on the quantity threshold #1. For example, when the terminal's height is in height range #2 (altitudeMin#2 to altitudeMax#2), the terminal can determine the quantity threshold as the quantity threshold #2 corresponding to height range #2, and thus perform the steps in the previous embodiment based on the quantity threshold #2.

[0237] For example, a hysteresis value, altitudeHyst, can be set for the height of the terminal. When the height of the terminal changes, the hysteresis value can be used to determine whether the height range corresponding to the terminal's height in the association relationship has changed.

[0238] For example, if a terminal's height is within height range #1, and the terminal's height subsequently changes, we can determine whether the terminal's height falls within range #1 (from altitudeMin#1 - altitudeHyst to altitudeMax#1 + altitudeHyst). If it remains within range #1, then the terminal's height is still within height range #1, and the corresponding height threshold remains at height threshold #1. If it falls outside range #1, then the terminal's height is no longer within height range #1, and the quantity threshold needs to be re-determined. This helps avoid resource waste caused by frequent changes in the quantity threshold due to terminal height fluctuations.

[0239] For example, the terminal can also determine the effective height range of the association. The terminal only determines the quantity threshold based on the association if the height is within the effective height range. For example, the effective height range can be represented by one of the following: upper height limit (altitudeMax) or lower height limit (altitudeMin).

[0240] For example, if the effective altitude range is only represented by the altitude limit altitudeMax, then the terminal will determine that the association takes effect when the altitude is lower than altitudeMax;

[0241] For example, if the effective altitude range is only represented by the lower altitude limit altitudeMin, then the terminal will determine that the association takes effect when the altitude is higher than altitudeMin;

[0242] For example, the effective altitude range is represented by the lower altitude limit (altitudeMin) and the upper altitude limit (altitudeMax). Then, the terminal determines that the association takes effect when the altitude is higher than altitudeMin but lower than altitudeMax.

[0243] For example, if the height of the terminal is not within the effective height range, then a default quantity threshold (e.g., 1) can be applied, or the default quantity threshold may not be specified or configured.

[0244] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.

[0245] In some embodiments, steps S201 and S202 may be performed in an alternate order or simultaneously.

[0246] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0247] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0248] In some embodiments, other optional implementations described before or after the specification corresponding to FIG2 may be referred to.

[0249] The technical solutions of this disclosure will be further illustrated by several embodiments below. The quantity threshold mentioned above may include a beam quantity threshold (e.g., denoted as X) or a cell quantity threshold (e.g., denoted as Y).

[0250] In some embodiments, the terminal triggers measurement reporting based on a beam count threshold configured on the network side. When the number of beams satisfying a measurement event is greater than (or greater than or equal to) the beam count threshold, the terminal initiates the measurement reporting process. The measurement event is an LTM measurement event.

[0251] For example, the number of beams that satisfy the measurement event is greater than (or greater than or equal to) a beam number threshold, wherein these beams that satisfy the measurement event come from at least a number of different neighboring cells (or candidate cells) of the cell number threshold, for example, the cell number threshold is also configured by the network side.

[0252] Example 1: The network side configures measurement configuration for the terminal. For example, the measurement configuration is used to configure L1 measurement, which includes measurement resource configuration and measurement reporting configuration.

[0253] For example, L1 measurement can be any one or more of the following: LTM measurement, CSI measurement, L2 measurement, beam measurement, measurement results reported by UCI, and measurement results reported by MAC CE.

[0254] For example, measurement resource configuration is used to configure the reference signal under test, such as configuring the SSB or CSI-RS under test. For example, measurement resource configuration can be CSI resource configuration.

[0255] For example, the measurement reporting configuration is used to configure the criteria and related parameters for measurement reporting, such as configuring the related parameters for measurement events, where measurement events include any one or more of Event LTM2 to 5.

[0256] Example 2: The network device configures a beam number threshold for the terminal. The beam number threshold configuration can be included in the measurement configuration. The beam number threshold is applicable to measurement reporting triggered by all measurement events; or, the beam number threshold configuration can be included in the measurement reporting configuration and is applicable to measurement reporting triggered by measurement events (e.g., specific measurement events) configured in this measurement reporting configuration.

[0257] Example 3: Based on Examples 1 and 2, the terminal performs measurement reporting based on the measurement configuration and beam count threshold (X), for example:

[0258] If the beam number threshold applies to a specific measurement event (e.g., the first measurement event), when the first number of beams in the beams corresponding to the measurement resource (or measurement resource set) associated with the specific measurement event satisfies the first relationship with X, then this event triggers a measurement report.

[0259] For example, different measurement resources (or measurement resource sets) correspond to different measurement resource (or measurement resource set) IDs, such as LTM CSI resource set ID. One measurement resource (or measurement resource set) corresponds to multiple beams and multiple neighboring cells or candidate cells or candidate cell configurations; that is, beams in the same measurement resource (or measurement resource set) can come from different neighboring cells or candidate cells.

[0260] For example, if the number of beams in the trigger beam list corresponding to a specific measurement event is greater than (or greater than or equal to) X, then this event triggers a measurement report; or if the number of beams in the trigger beam list corresponding to this event becomes greater than (or greater than or equal to) X (for example, from less than X to greater than (or greater than or equal to) X), then this event triggers a measurement report.

[0261] If the beam count threshold applies to all events, and if the total number of beams satisfying different events currently satisfies the first relationship with X, then the terminal generates a measurement report (e.g., Measurement Report MAC CE) based on the measurement results of these events and sends it to the network.

[0262] For example, if the total number of beams in the trigger beam list corresponding to all events is greater than (or greater than or equal to) X, the terminal will perform a measurement report; or if the total number of beams in the trigger beam list corresponding to all events becomes greater than (or greater than or equal to) X (for example, from less than X to greater than (or greater than or equal to) X), the terminal will perform a measurement report.

[0263] Example 4: The network device can also configure a cell number threshold (Y) for the terminal. The cell number threshold configuration can be included in the measurement configuration. This parameter applies to measurement reporting triggered by all measurement events; or, the configuration of this parameter can be included in the measurement reporting configuration, which applies to measurement reporting triggered by measurement events configured in this measurement reporting configuration.

[0264] Example 5: Based on Examples 3 and 4, if Y is configured on the network side, the terminal also needs to determine whether to trigger measurement reporting based on Y.

[0265] If the beam count threshold applies to a specific measurement event (e.g., the first measurement event), when the first number of beams corresponding to the measurement resource / measurement resource set associated with the event satisfies a first relationship with X, and these beams satisfying the first measurement event come from at least Y cells, then this event triggers a measurement report.

[0266] For example, different measurement resources (or measurement resource sets) correspond to different measurement resource (or measurement resource set) IDs, such as LTM CSI resource set ID. One measurement resource (or measurement resource set) corresponds to multiple beams and multiple neighboring cells or candidate cells or candidate cell configurations; that is, beams in the same measurement resource (or measurement resource set) can come from different neighboring cells or candidate cells.

[0267] If the beam count threshold applies to all events, and if the total number of beams satisfying different events satisfies the first relationship with X, and the beams satisfying these events come from at least Y cells, then the terminal generates a measurement report (e.g., Measurement Reporting MAC CE) based on the measurement results of these events and sends it to the network.

[0268] In some embodiments, the network device configures the association between terminal height and beam number threshold X and / or cell number threshold Y, for example, different height ranges correspond to different beam number thresholds. The height range can be determined by a height threshold or by height-based events.

[0269] Example 6: For example, in Examples 2 and 4, the configuration of the beam number threshold X and / or cell number threshold Y includes the association between the terminal's height and the beam number threshold X and / or cell number threshold Y. The terminal can determine whether X and Y are effective based on its height, and the values ​​of effective X and Y. Then, based on the effective X and Y, it can perform the relevant operations in Examples 1 to 5, for example:

[0270] Network devices can configure one or more groups of terminal height ranges and corresponding beam number thresholds X and / or cell number thresholds Y; if a terminal is outside the configured height range, X and Y are default values, which can be 1 or it can be assumed that X and Y are not configured on the network side.

[0271] For example, the parameters for the height range are as follows:

[0272] Minimum altitude threshold: altitudeMin

[0273] Maximum altitude threshold: altitudeMax

[0274] Hysteresis value: altitudeHyst

[0275] If both the minimum height threshold and the maximum height threshold are configured, the height range is: altitudeMin ≤ terminal height ≤ altitudeMax.

[0276] If a minimum height threshold is configured, the height range is altitudeMin ≤ terminal height;

[0277] If a maximum height threshold is configured, the height range is terminal height ≤ altitudeMax.

[0278] For example, the hysteresis value is used to assess whether the terminal has left this altitude range. When the terminal altitude satisfies altitudeMin≤terminalalheight≤altitudeMax, if the terminal altitude satisfies (altitudeMin-altitudeHyst)≤terminalalheight≤(altitudeMax+altitudeHyst), then the terminal is considered to still be within this altitude range; otherwise, the terminal is considered to have left this altitude range (or is not within this altitude range).

[0279] For example, network devices can configure altitude events for the effective beam number threshold X and / or cell number threshold Y. If the terminal meets the corresponding altitude event, the corresponding beam number threshold X and / or cell number threshold Y will be effective; otherwise, they will be ineffective. If there are no effective X or Y, X and Y will be default values, which can be 1 or it can be assumed that X and Y are not configured on the network side.

[0280] For example, an event may include at least one of the following:

[0281] Event H1: Aerial UE altitude becomes higher than a threshold.

[0282] Event H2: Aerial UE altitude becomes lower than a threshold;

[0283] Event H3: The terminal altitude becomes higher than a threshold 1 and the terminal altitude becomes lower than a threshold 2.

[0284] In some embodiments, when the number of beams satisfying a measurement event is greater than (or greater than or equal to) a beam number threshold, the terminal initiates the measurement reporting process. For the next measurement reporting trigger, the terminal will only trigger measurement reporting again if the number of newly satisfied beams for this event is greater than (or greater than or equal to) the beam number threshold, or if the number of unreported beams is greater than (or greater than or equal to) the beam number threshold.

[0285] For example, in the corresponding measurement report MAC CE, the terminal prioritizes reporting the measurement results of the newly satisfied beam.

[0286] Example 7: The terminal can compare previously reported measurement results (e.g., the most recent measurement report for this measurement event). If a beam not included in the previous report, or a beam that did not meet the event in the previous report, becomes the event, and the number of these beams is greater than (or greater than or equal to) X, then a measurement report is triggered again. (This example can also simultaneously evaluate whether requirement Y is met).

[0287] For example, the number of newly added beams in the trigger beam list corresponding to this event is greater than (or greater than or equal to) X, and these newly added beams come from at least Y cells.

[0288] Example 8: Due to the limited size of the MAC CE, the terminal may not be able to report all measurement results at once. For example, a truncated measurement report MAC CE can be used, with the terminal prioritizing the reporting of measurement results for beams that newly satisfy this event. Alternatively, the first UL grant corresponding to this measurement report MAC CE should prioritize sending the measurement results of beams that newly satisfy this event.

[0289] In some embodiments, for measurement reporting triggered by a departure condition, the corresponding departure report will only be triggered if the beam that has been reported in a previous measurement report meets the departure condition. If the beam meets the measurement event but its measurement result is not included in a previous measurement report, the measurement report will not be triggered even if the departure condition is met.

[0290] Example 9: If the network side is configured with a first indication, the first indication is used to indicate whether to perform measurement reporting when the terminal evaluates that a specific beam meets the departure condition. Then, by comparing the previously reported measurement results (e.g., the most recent measurement report for this measurement event), if the beam included in the previous report, or the beam that met the event in the previous report, meets the departure condition, then a departure measurement report is triggered.

[0291] In some embodiments, if X and / or Y are configured, the number of beams that meet the departure conditions described in Embodiment 9 needs to meet the requirements of X, and / or the corresponding number of cells needs to meet the requirements of Y.
