Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a measurement reporting method and device. Background Art

[0002] As a new type of aircraft, uncrewed aerial vehicle (UAV) is gradually becoming popular due to its flexible and convenient use. Cellular networks can provide UAVs with important features such as wide coverage, high reliability, high security, and continuous mobility. The communication environment of UAVs is somewhat different from that of ordinary terminals. UAVs mainly fly above network devices and can connect to network devices through the Uu port, and mainly communicate in line of sight (LOS) path. Summary of the invention

[0003] The present application provides a measurement reporting method and device, which can determine whether to trigger measurement reporting according to thresholds corresponding to one or more state information, thereby improving the timeliness and accuracy of measurement reporting.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] In a first aspect, a measurement reporting method is provided, which is applied to a terminal, including: obtaining configuration information, the configuration information including at least one state information and at least one threshold, the at least one state information including first state information and second state information, the at least one threshold including a first threshold and a second threshold, the first threshold corresponding to the first state information, the second threshold corresponding to the second state information, the first threshold used to indicate the number of cells detected by the terminal for measurement reporting that meet a trigger event, and the second threshold used to indicate the number of cells detected by the terminal for measurement reporting that meet a trigger event; and performing measurement reporting according to the first threshold and the second threshold.

[0006] This application can determine whether to trigger measurement reporting based on thresholds corresponding to one or more state information, so as to avoid omissions and repeated reporting of measurement results, and improve the timeliness and accuracy of measurement reporting.

[0007] In a possible design, the state of the terminal is switched from a first state to a second state, the first state corresponds to the first state information, and the second state corresponds to the second state information.

[0008] This application can determine whether to trigger measurement reporting based on thresholds corresponding to one or more state information, so as to avoid omissions and repeated reporting of measurement results, and improve the timeliness and accuracy of measurement reporting.

[0009] In one possible design, the first threshold is determined based on the first state and configuration information, and the first state corresponds to the first state information; and / or the second threshold is determined based on the second state and configuration information, and the second state corresponds to the second state information.

[0010] The present application can determine the corresponding threshold value according to the state and configuration information of the terminal, so that the terminal can use the appropriate threshold value to determine whether to trigger measurement reporting in the corresponding state, thereby improving the timeliness and accuracy of measurement reporting.

[0011] In one possible design, measurement reporting is performed based on a first threshold and a second threshold, including: when the number of cells in the second cell list is greater than or equal to the second threshold, and the number of cells in the second cell list is less than or equal to the first threshold, sending a measurement report to a network device, and the second cell list includes cells that meet the trigger event.

[0012] In this application, the terminal can determine to trigger the measurement report reporting according to the first threshold and the second threshold. When the first threshold and the second threshold meet the corresponding conditions, the terminal can timely report the measurement report of the cell in the second cell list to avoid underreporting of the measurement results. This improves the timeliness of the measurement reporting.

[0023] The present application can timely report the measurement results of new cells obtained by measurement to the network device, and can also avoid repeated reporting of measurement results by some cells, reduce the redundancy of measurement reports, and reduce signaling overhead.

[0024] In one possible design, at least one state information also includes at least one third state information, and at least one threshold also includes at least one third threshold, the third threshold corresponds to the third state information, and the third threshold is used to indicate the number of cells detected by the terminal that meet the trigger event for measurement reporting.

[0025] This application can configure the correspondence between multiple groups of status information and thresholds so that the terminal can determine whether to trigger measurement reporting based on the thresholds corresponding to one or more status information, so as to avoid omissions and repeated reporting of measurement results, and improve the timeliness and accuracy of measurement reporting.

[0026] In one possible design, one of the at least one status information includes at least one of the flight altitude information of the terminal, the moving speed information of the terminal, or the location area information of the terminal.

[0027] The present application provides multiple possible representations of status information so that the terminal can determine whether to trigger measurement reporting based on thresholds corresponding to one or more status information, thereby improving universality.

[0070] Figure 1 This is an example diagram of the architecture of the communication system provided in an embodiment of the present application.

Figure 1 This is just a schematic diagram.

[0072] The wireless access network device may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a fifth generation (5G) mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes some functions of a base station, for example, a centralized unit (CU) or a distributed unit (DU). The wireless access network device may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. The wireless access network device is sometimes also referred to as a network device. For ease of description, the following description takes a base station as an example of a wireless access network device, which is uniformly described here and will not be repeated.

[0073] Terminal devices may also be referred to as terminals, user equipment (UE), mobile stations, mobile terminals, etc. Terminal devices can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. Terminal devices may be mobile phones, tablet computers, computers with wireless transceiver functions, wearable devices, vehicles, drones, various devices on drones and other aircraft, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal devices.

[0074] Base stations and terminal devices can be fixed or mobile. Base stations and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons, and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of base stations and terminal devices.

[0075] Base stations and terminal devices, base stations and base stations, and terminal devices and terminal devices can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz.

[0077] UAV is a new type of aircraft. The communication environment of UAV can be referred to as Figure 1 The scene shown.

[0078] Load balancing in new radio (NR) can be achieved through handover, redirection mechanism during radio resource control (RRC) release, and by using absolute priorities preset by heterogeneous frequencies and heterogeneous systems. For each measurement type, one or more measurement objects can be defined, and for each measurement object, one or more measurement report configurations can be defined, and the measurement report configuration defines the measurement report standard. In some instances, there are three measurement reporting criteria. That is, event-triggered reporting, periodic reporting, and event-triggered periodic reporting.

[0079] In some instances, the measurement event may include at least one of an A event and an H event. For example, an A event may include A1, A2, A3, A4, and A5. H events related to drones may include H1 and H2. A events and H events may include: A3H1, A3H2, A4H1, A4H2, A5H1, A5H2, etc. Among them, the A1 event may indicate that the service quality of the serving cell is higher than a certain threshold, and may be used to turn off the measurement of certain cells. The A2 event may indicate that the service quality of the serving cell is lower than a certain threshold, and may be used to turn on the measurement of certain cells. For example, after the A2 event occurs, operations such as cell switching may be triggered. The A3 event may indicate that the service quality of the neighboring cell is better than that of the serving cell, and may be used to determine whether the terminal switches to the neighboring cell. The A4 event may indicate that the service quality of the neighboring cell is higher than a certain threshold. The A5 event may indicate that the service quality of the serving cell is lower than a certain threshold, and the service quality of the neighboring cell is higher than another threshold. The H1 event may indicate that the height of the air terminal is higher than a certain threshold. The H2 event may indicate that the height of the air terminal is lower than a certain threshold. For example, AxHy events such as A3H1 indicate that both the corresponding A event and the corresponding H event need to be satisfied to trigger the terminal to report the measurement report.

[0080] In some embodiments, a trigger mechanism for triggering terminal measurement reporting is provided. For example, within the trigger time (trigger to time, TTT) of a cell, the layer (layer, L) 3 filtering result always meets the corresponding trigger event. The terminal records the cell in the triggered cell list (cells triggered list) and sends the measurement report of each cell in the triggered cell list. For example, in the process of recording cells in the triggered cell list, when it is greater than or equal to the preset threshold N for the first time, the measurement report of each cell in the triggered cell list is reported. After the number of cells in the triggered cell list is greater than or equal to N, if there is a new cell that meets the trigger event, the terminal can continue to add the cell to the triggered cell list, but does not trigger the measurement report, that is, does not report the measurement result of the new cell.

[0081] It is understandable that the mobile communication system was originally involved in ground terminals, but with the increasing popularity of drones, the 3rd generation partnership project (3GPP) enhanced the measurement mechanism for drones in release (R) 15. The communication environment for drones in the air is very different from that on the ground. First of all, since network devices radiate electromagnetic waves toward the ground, the signals in the air are basically reflections of ground signals and beam sidelobes of base stations. This will cause the signal received by the drone to be relatively weak. In addition, since drones are mainly based on LOS paths in the air, drones can receive more signals sent by network devices, thereby triggering more and more frequent measurement reports.

[0082] In some embodiments, for the above situation, the network device can configure the number of triggering cells for the terminal, that is, the N mentioned above. During the process of the terminal performing cell measurement, if the L3 filtering result of a certain cell within the TTT always meets the corresponding triggering event, the terminal can add the cell to the triggering cell list. For example, when the number of cells in the triggering cell list is greater than or equal to N, the terminal can send a measurement report of each cell in the triggering cell list to the network device.

[0083] In some embodiments, the related technology provides a measurement reporting method, such as Figure 2 As shown, this method can be applied Figure 1 The method may include the following steps:

[0084] S201, the network device sends configuration information to the terminal.

[0085] In some embodiments, the network device may configure configuration information for the terminal, and the configuration information may include a number of trigger cells based on altitude. For example, the terminal may be a drone, and the network device may be a base station.

[0086] For example, the base station configures one or more sets of correspondences between altitude and triggering cell numbers, and / or one or more sets of correspondences between altitude ranges and triggering cell numbers for the UAV, such as correspondence 1, correspondence 2, correspondence 3, and correspondence 4. Among them, correspondence 1 can be 100 meters (m) and the number of triggering cells is 3; correspondence 1 can be 200m and the number of triggering cells is 4; correspondence 3 can be 100m-200m and the number of triggering cells is 3; correspondence 4 can be 200m-300m and the number of triggering cells is 3.

[0087] Of course, the above correspondence is only an exemplary description and is not limited to this in the embodiments of the present application.

[0088] In some embodiments, the network device may send a configured correspondence between one or more sets of heights and the number of trigger cells to the terminal, that is, send configuration information. It is understandable that the configuration information includes a correspondence between one or more sets of heights and the number of trigger cells.

[0089] S202: The terminal determines to trigger measurement reporting according to the number of cells in the triggered cell list.

[0090] In some embodiments, the terminal may determine the current altitude or altitude range of the terminal. Afterwards, the terminal may determine the corresponding number of triggering cells N according to the correspondence between one or more groups of altitudes and the number of triggering cells received in S201, combined with the current altitude of the terminal. Alternatively, the terminal may determine the corresponding number of triggering cells N according to the correspondence between one or more groups of altitude ranges and the number of triggering cells received in S201, combined with the current altitude range of the terminal. Then, the terminal may measure the cells and add the cells that meet the triggering event to the triggering cell list. The terminal may determine whether to trigger reporting of the measurement results based on N and the number of cells in the triggering cell list.

[0091] For example, the terminal measures the cell and adds the cell that meets the triggering event into the triggering cell list. The number of cells in the triggering cell list can be recorded as F. During the process of the terminal measuring the cell, if F changes from less than N to F greater than or equal to N, the measurement report is triggered.

[0092] The cell that meets the triggering event may be a cell that meets the measurement event such as A1, H2, A3H1 as the triggering condition.

[0093] For another example, if F is greater than or equal to N, the terminal adds the cell satisfying the triggering event into the triggering cell list, but does not trigger reporting of the measurement result to the network device.

[0094] However, in the above-mentioned solution, when the drone reaches a new altitude or altitude range, the drone can apply the number of trigger cells corresponding to the new altitude or altitude range. For example, the number of trigger cells corresponding to the original altitude or altitude range is recorded as N1, and the number of trigger cells corresponding to the new altitude or altitude range is recorded as N2. So when the terminal reaches a new altitude or altitude range, how to deal with the cells in the trigger cell list is still undecided.

[0095] The terminal processes the cells in the triggering cell list in the following situations.

[0096] For example, when the drone reaches a new height or height range during flight, but the number of cells F in the trigger cell list has not changed, it is assumed that F changes from less than N1 to F greater than or equal to N2. If the terminal keeps the trigger cell list unchanged after applying N2, the terminal will not trigger the reporting of the measurement results. Because the relevant technology is aimed at the situation where the number of cells in the trigger cell list changes, it regulates the conditions for terminal measurement reporting. However, the above scheme does not consider the situation where the number of trigger cells changes. Therefore, when the number of trigger cells changes, even if the number of cells F in the measurement cell list is greater than or equal to N2, since no new cells are added to the trigger cell list, the measurement results of the reported cells will not be triggered. In other words, for the situation where the number of trigger cells changes, if the terminal does not measure a cell that meets the trigger event in the new height or height range, no new cell will be added to the trigger cell list. The terminal will not trigger the determination of the relationship between the number of cells in the measurement cell list and the number of trigger cells, and will not trigger the reporting of the measurement results of the cells. Of course, even if new cells are added to the trigger cell list, the existing protocol process first determines whether the cells in the trigger cell list are greater than or equal to the number of trigger cells. If it is greater than or equal to the number, only the cells that meet the trigger event are added to the trigger cell list, and measurement reporting is not triggered.

[0097] For another example, when the drone reaches a new altitude or altitude range during flight. However, the number of cells F in the trigger cell list has not changed. Assume that F is greater than or equal to N1 and changes to F greater than or equal to N2. If the terminal removes the cells in the original trigger cell list after applying N2, the terminal may add the previously removed cells to the trigger cell list again during subsequent cell measurements. Then, when the number of cells in the trigger cell list is greater than or equal to N2, the terminal triggers measurement reporting. However, the measurement results of these cells that are added to the trigger cell list again will also be reported again. However, the measurement results of these cells may have been reported before the altitude or altitude range changed, resulting in duplicate reporting.

[0098] Therefore, the embodiment of the present application provides a measurement reporting method, which determines whether to perform measurement reporting through thresholds corresponding to different state information, so that the measured cell can be reported to the network device in time to avoid omissions, repeated reports, etc.

[0099] Figure 3 A schematic diagram of another measurement reporting method interaction provided in an embodiment of the present application.

[0100] like Figure 3 As shown, the cell measurement process can be applied to Figure 1In the communication scenario shown or other similar communication scenarios, the method may include the following steps:

[0101] S301, the network device sends configuration information to the terminal.

[0102] In some embodiments, the network device may generate configuration information, wherein the configuration information may include at least one state information and at least one threshold value, wherein the threshold value may be used by the terminal to determine whether to trigger measurement reporting in the state corresponding to the corresponding state information.

[0103] In some embodiments, the network device may send configuration information, and the terminal may receive the configuration information sent by the network device.

[0104] In some embodiments, the configuration information may also be pre-configured on the terminal, and the terminal may obtain the pre-stored configuration information.

[0105] In some embodiments, at least one state information may include first state information and second state information. The first state information may correspond to a first state of the terminal, and the second state information may correspond to a second state of the terminal. At least one threshold may include a first threshold and a second threshold. The first threshold may correspond to the first state information, and the second threshold may correspond to the second state information.

[0106] For example, the first threshold value may be used to indicate the number of cells for which the terminal detects a trigger event and performs measurement reporting. For example, when the terminal is in a first state corresponding to the first state information, the first threshold value may be used to determine whether to trigger the measurement report. For another example, the second threshold value may be used to indicate the number of cells for which the terminal detects a trigger event and performs measurement reporting. For example, when the terminal is in a second state corresponding to the second state information, the second threshold value may be used to determine whether to trigger the measurement report.

[0107] For example, the first threshold is N1 and the second threshold is N2. Then, in the first state, the terminal can determine whether to trigger measurement reporting according to N1; and in the second state, the terminal can determine whether to trigger measurement reporting according to N2.

[0108] In some embodiments, the at least one state information may further include more other state information, for example, at least one third state information. The at least one threshold may further include more other thresholds, for example, at least one third threshold. The third threshold corresponds to the third state information, and the third threshold may be used to indicate the number of cells detected by the terminal that meet the trigger event for measurement reporting.

[0109] For example, the third threshold may be used to indicate the number of cells detected by the terminal that meet the triggering event for measurement reporting. For example, when the terminal is in the third state corresponding to the third state information, the third threshold may be used to determine whether to trigger measurement reporting.

[0110] The third state information is different from both the first state information and the second state information. The third state information can be considered as other state information except the first state information and the second state information.

[0111] This application can configure the correspondence between multiple groups of status information and thresholds so that the terminal can determine whether to trigger measurement reporting based on the thresholds corresponding to one or more status information, thereby avoiding omissions and repeated reporting of measurement results and improving the timeliness and accuracy of measurement reporting.

[0112] In some embodiments, the terminal may be a drone. The drone may support communication with a network device.

[0113] Of course, the terminal may also be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a flying vehicle, a helicopter, an airplane, a flying robot, any possible aerial vehicle, etc. The embodiment of the present application does not limit the specific device form adopted by the terminal.

[0114] In some embodiments, the network device may be an access network device. For example, the network device may be a base station, which may perform access management and handover management on the network device. Furthermore, the base station may communicate with a core network.

[0115] Of course, the network device can also be an access node such as eNodeB, TRP, gNB, and the next generation base station in 6G. The embodiment of the present application does not limit the specific device form adopted by the network device.

[0116] S302: The terminal performs measurement reporting according to the first threshold and / or the second threshold.

[0117] In some embodiments, the terminal may perform measurement reporting according to the first threshold and the second threshold.

[0118] For example, the terminal may perform measurement reporting according to the first threshold and the second threshold. For example, the terminal may determine whether to trigger measurement reporting according to the relationship between the number of cells in the current triggered cell list and the first threshold, and the relationship between the number of cells in the current triggered cell list and the second threshold.

[0119] For example, the terminal may determine a threshold value corresponding to the height or height range, such as a second threshold value, based on the current height or height range of the terminal. The terminal may perform measurement reporting based on the second threshold value and the first threshold value corresponding to the original height or height range of the terminal. For example, the terminal may determine a threshold value N2 corresponding to the height 2 or height range 2 based on the current height 2 or height range 2. The terminal may perform measurement reporting based on N2 and N1 corresponding to the original height 1 or height range 1 of the terminal.

[0120] This application can determine whether to trigger measurement reporting based on thresholds corresponding to one or more state information, so as to avoid omissions and repeated reporting of measurement results, and improve the timeliness and accuracy of measurement reporting.

[0121] In a measurement reporting method provided in an embodiment of the present application, the state of the terminal is switched from a first state to a second state, wherein the first state corresponds to the first state information, and the second state corresponds to the second state information.

[0122] In some embodiments, when the state of the terminal is switched from the first state to the second state, measurement reporting may be performed according to the first threshold and the second threshold.

[0123] For example, when the state of the terminal switches from the first state to the second state, it may be determined to trigger measurement reporting according to the first threshold and the second threshold, that is, the terminal sends a measurement report.

[0124] For another example, when the state of the terminal switches from the first state to the second state, it may be determined not to trigger measurement reporting according to the first threshold and the second threshold, that is, the terminal does not send a measurement report.

[0125] This application can determine whether to trigger measurement reporting according to thresholds corresponding to one or more state information when the state of the terminal switches, so as to avoid omissions and repeated reporting of measurement results, and improve the timeliness and accuracy of measurement reporting.

[0126] In a measurement reporting method provided in an embodiment of the present application, a first threshold is determined according to a first state and configuration information; and / or a second threshold is determined according to a second state and configuration information.

[0127] In some embodiments, the terminal may determine a corresponding threshold value according to the current state and configuration information of the terminal.

[0128] For example, when the terminal is in the first state, the terminal can determine the corresponding first threshold value according to the first state and the configuration information. The first state corresponds to the first state information, so the terminal in the first state can determine the first threshold value corresponding to the first state information according to the configuration information.

[0129] For another example, the terminal is in the second state, and the terminal can determine the corresponding second threshold value according to the second state and the configuration information. The second state corresponds to the second state information, so the terminal in the second state can determine the second threshold value corresponding to the second state information according to the configuration information.

[0130] Similarly, the third threshold value can also be determined by referring to the above process, which will not be elaborated in the embodiment of the present application.

[0131] For example, assuming that the terminal is in the state of flying at an altitude of 100m, the terminal can determine the corresponding threshold value according to the state of flying at an altitude of 100m and the configuration information. Among them, the configuration information includes the corresponding relationship between 100m and the threshold value N01, that is, the state information is 100m. 100m corresponds to the state of flying at an altitude of 100m. Then the terminal flying at an altitude of 100m can determine the threshold value N01 according to the corresponding relationship between 100m and N01.

[0132] It can be understood that since the configuration information configures a correspondence between one or more groups of state information and thresholds, the terminal can determine a suitable threshold according to the state information corresponding to the current state of the terminal and the configuration information, so that the terminal performs measurement reporting based on the threshold.

[0133] In a measurement reporting method provided in an embodiment of the present application, performing measurement reporting according to a first threshold and a second threshold may include: when the number of cells in the second cell list is greater than or equal to the second threshold, and the number of cells in the second cell list is less than or equal to the first threshold, sending a measurement report to a network device. The second cell list includes cells that meet the triggering event.

[0134] In some embodiments, the terminal may use the first threshold and the second threshold to determine to perform measurement reporting. For example, the terminal may determine to send a measurement report based on the number of cells in the second cell list being greater than or equal to the second threshold and the number of cells in the second cell list being less than the first threshold.

[0135] Those skilled in the art will appreciate that it is worth noting that in each embodiment of the present application, the second cell list can be used to represent the trigger cell list mentioned above. For example, the terminal is in state B, and the trigger cell list of the terminal in state B can be considered to be the second cell list mentioned above.

[0136] For example, assume that the number of cells in the second cell list is recorded as F1, the first threshold is N1, and the second threshold is N2. When the terminal is in the second state, if F1 is greater than or equal to N2, and F1 is less than N1, the terminal can determine to send a measurement report to the network device. The measurement report includes the measurement results of one or more cells in the second cell list. For example, the measurement report may include the measurement results of each cell in the second cell list. Among them, the cells in the second cell list may include cells that meet the trigger event in the first state, and may also include cells where the terminal meets the trigger event in the second state.

[0137] It should be noted that in each embodiment of the present application, the trigger events satisfied in different states may be the same or different, and the embodiments of the present application are not limited thereto.

[0138] For example, assuming that the second cell list includes cell 1, cell 2, and cell 3, N1 corresponding to the first height information is 5, and N2 corresponding to the second height information is 2. If the terminal is at the second height, the second height information N2, that is, 2, can be determined according to the second height information corresponding to the second height and the configuration information. The terminal can determine the number of cells in the second cell list, that is, F1 is 3. Obviously, 3 is greater than 2 and 3 is less than 5, which satisfies that F1 is greater than or equal to N2, and F1 is less than N1. The terminal can send a measurement report to the network device, which includes the measurement results of cell 1, the measurement results of cell 2, and the measurement results of cell 3.

[0139] In the present application, the terminal can determine to trigger the measurement report reporting according to the first threshold and the second threshold, so that when the first threshold and the second threshold meet the corresponding conditions, the terminal can timely report the measurement report of the cell in the second cell list to avoid underreporting of the measurement results, thereby improving the timeliness of the measurement reporting.

[0140] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0141] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. Among them, the position can be considered as the state information mentioned in the above embodiments, and the trigger cell number can be the threshold mentioned in the above embodiments. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. In some cases, the drone can retain the cells in the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11, the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22, and the number of cells in the trigger cell list is X33. In this case, when X33 is less than N11 and becomes X33 greater than or equal to N12, the drone can trigger the measurement report to ensure that the drone can report the measurement report of the cells in the trigger cell list in a timely manner.

[0142] For example Figure 4 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding trigger cell number N11 is 4; when the drone is at altitude 2 or altitude range 2, the corresponding trigger cell number N22 is 3; the number of cells X33 in the second cell list is 3. In this case, X33 is equal to N22, and X33 is less than the previously configured N11, and the drone triggers the measurement report.

[0143] In a measurement reporting method provided in an embodiment of the present application, measurement reporting is performed according to a first threshold and a second threshold, which may include one or more of the following situations.

[0144] In some embodiments, the terminal may use the first threshold and the second threshold to determine to perform measurement reporting. For example, the terminal may determine not to trigger measurement reporting based on the number of cells in the second cell list being greater than or equal to the second threshold and the number of cells in the second cell list being greater than or equal to the first threshold. That is, the terminal does not send a measurement report to the network device.

[0145] For example, assume that the number of cells in the second cell list is recorded as F1, the first threshold is N1, and the second threshold is N2. When the terminal is in the second state, if F1 is greater than or equal to N2, and F1 is greater than or equal to N1, the cells in the second cell list can maintain the cells in the triggering cell list unchanged, and continue to perform cell measurement. For example, the original triggering cell list of the terminal includes cell 1, cell 2 and cell 3. When the terminal is in the second state, the cells in the second cell list can be maintained as cell 1, cell 2 and cell 3. If the terminal determines that a certain cell meets the triggering event, the terminal can add the cell to the second cell list, but the terminal does not send a measurement report. It can be understood that in this example, since F1 is greater than or equal to N1, it can be considered that the terminal has reported a measurement report when it is in the first state corresponding to N1. To avoid repeated reporting, the terminal may not trigger measurement reporting.

[0146] For example, assuming that the number of cells in the second cell list is F1, the first threshold corresponding to height 1 or height range 1 is N1, and the second threshold corresponding to height 2 or height range 2 is N2. When the terminal is at height 2 or height range 2, if F1 is greater than or equal to N2, and F1 is greater than or equal to N1, the cells in the second cell list remain unchanged from the cells in the original triggering cell list. At this time, the terminal does not trigger the sending of the measurement report. Even if the terminal determines that a cell meets the corresponding trigger event, the terminal can add the cell to the second cell list, but still will not send a measurement report.

[0147] Of course, the number of cells in the second cell list may be less than N2 due to some reasons. When the number of cells in the second cell list is greater than or equal to N2 again, the measurement report may be triggered again.

[0148] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0149] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. The drone can retain the cells in the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11, the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22, and the number of cells in the trigger cell list is X33. Figure 4 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding trigger cell number N11 is 2; when the drone is at altitude 2 or altitude range 2, the corresponding trigger cell number N22 is 3; the number of cells in the second cell list X33 is 3. In this case, X33 is greater than N22, and X33 is greater than the previously configured N11, and the drone maintains the cells in the trigger cell list. Optionally, the drone does not trigger measurement reporting.

[0150] In some embodiments, the terminal may use the first threshold and the second threshold to determine to perform measurement reporting. For example, the terminal may determine not to trigger measurement reporting based on the number of cells in the second cell list being less than the second threshold and the number of cells in the second cell list being greater than or equal to the first threshold. That is, the terminal does not send a measurement report to the network device.

[0151] For example, assume that the number of cells in the second cell list is recorded as F1, the first threshold is N1, and the second threshold is N2. When the terminal is in the second state, if F1 is less than N2, and F1 is greater than or equal to N1, the cells in the second cell list can maintain the cells in the triggering cell list unchanged and continue to perform cell measurement. If the terminal determines that a certain cell meets the triggering event, the terminal can add the cell to the second cell list. Until F1 is greater than or equal to N2, the terminal is triggered to report the measurement report. The measurement report includes the measurement results of one or more cells in the current second cell list, for example, the measurement report includes the measurement results of each cell in the current second cell list. Of course, if a cell that meets the triggering event appears again, the terminal can continue to add the cell to the second cell list. In the case where the terminal continues to determine that F1 is greater than or equal to N2, the sending of the measurement report is not triggered. However, in the case where F1 is less than N2 due to some reasons and F1 is greater than or equal to N2 again, the terminal can trigger the measurement report again.

[0152] For example, assuming that the number of cells in the second cell list is F1, the first threshold corresponding to height 1 or height range 1 is N1, and the second threshold corresponding to height 2 or height range 2 is N2. When the terminal is at height 2 or height range 2, if F1 is less than N2, and F1 is greater than or equal to N1, the cells in the second cell list remain unchanged in the original trigger cell list. At this time, continue to perform cell measurement, and add the cells that meet the corresponding trigger event to the second cell list. Until F1 is greater than or equal to N2, the terminal is triggered to report the measurement report.

[0153] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0154] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. The drone can retain the cells in the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11, the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22, and the number of cells in the trigger cell list is X33. Figure 4 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding trigger cell number N11 is 3; when the drone is at altitude 2 or altitude range 2, the corresponding trigger cell number N22 is 5; the number of cells X33 in the second cell list is 3. In this case, X33 is less than N22, and X33 is equal to the previously configured N11, and the drone maintains the cells in the trigger cell list.

[0155] In some embodiments, the terminal may use the first threshold and the second threshold to determine to perform measurement reporting. For example, the terminal may determine not to trigger measurement reporting based on the number of cells in the second cell list being less than the second threshold and the number of cells in the second cell list being less than the first threshold. That is, the terminal does not send a measurement report to the network device.

[0156] Among them, the implementation process of this embodiment is similar to the implementation process of the above-mentioned "the terminal determines not to trigger measurement reporting based on the number of cells in the second cell list being less than the second threshold, and the number of cells in the second cell list being greater than or equal to the first threshold". For the convenience of description, the embodiment of the present application will not be repeated here.

[0157] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0158] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. The drone can retain the cells in the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11, the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22, and the number of cells in the trigger cell list is X33. Figure 4 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding trigger cell number N11 is 4; when the drone is at altitude 2 or altitude range 2, the corresponding trigger cell number N22 is 5; the number of cells X33 in the second cell list is 3. In this case, X33 is less than N22, and X33 is less than the previously configured N11, and the drone maintains the cells in the trigger cell list.

[0159] It can be understood that when the number of cells in the second cell list is less than the second threshold, F1 is not greater than or equal to N2. Therefore, regardless of whether the terminal satisfies F1 greater than or equal to N1 in the first state, the terminal can maintain the cells in the triggered cell list unchanged and not trigger measurement reporting in the second state. In this case, the terminal continues to perform cell measurement until F1 is greater than or equal to N2 and then triggers measurement reporting.

[0160] The embodiments of the present application provide multiple situations in which the terminal determines whether to trigger measurement report reporting based on the first threshold and the second threshold, so that the terminal may not trigger measurement reporting in some situations to avoid repeated reporting and reduce signaling overhead.

[0161] In some possible implementations, in S302, the terminal may also perform a measurement reporting process according to the second threshold.

[0162] In some embodiments, the terminal may receive configuration information sent by the network device. The terminal determines a threshold corresponding to the current state based on the state information and configuration information corresponding to the current terminal state. If the terminal is in the second state, the second threshold may be determined based on the second state information and configuration information corresponding to the second state. The terminal performs measurement reporting based on the second threshold.

[0163] For example, when the terminal is in the second state, it can be determined according to the second threshold whether to trigger the measurement report. That is, the terminal sends a measurement report. The measurement report includes measurement results corresponding to one or more cells. The one or more cells are cells in the second cell list. For another example, when the terminal is in the second state, it can be determined according to the second threshold whether to trigger the measurement report. That is, the terminal does not send a measurement report.

[0164] In some embodiments, the terminal may determine to send the measurement report according to the number of cells in the second cell list being greater than or equal to a second threshold.

[0165] For example, assume that the number of cells in the second cell list is recorded as F1, the first threshold is N1, and the second threshold is N2. When the terminal is in the second state, if F1 is greater than or equal to N2, the terminal can determine to send a measurement report to the network device. The cells in the second cell list can maintain the cells in the triggering cell list unchanged, or the cells in the triggering cell list can be adjusted, which is not limited in the embodiment of the present application. The measurement report includes the measurement results of the cells in the second cell list.

[0166] For example, assuming that the number of cells in the second cell list is recorded as F1, and the second threshold corresponding to height 2 or height range 2 is N2. When the terminal is at height 2 or height range 2, if F1 is greater than or equal to N2, the terminal can send a measurement report to the network device. The measurement report includes the measurement results of one or more cells in the second cell list. It can be understood that the cells in the second cell list can maintain the cells in the original trigger cell list unchanged, and the cells in the second cell list can also be obtained by adjusting the cells in the original trigger cell list.

[0167] In some embodiments, the terminal may determine not to trigger measurement reporting according to the number of cells in the second cell list being less than the second threshold, that is, the terminal does not send a measurement report to the network device.

[0168] For example, assuming that the number of cells in the second cell list is F1, the first threshold is N1, and the second threshold is N2. When the terminal is in the second state, if F1 is less than N2, the terminal may determine not to send a measurement report.

[0169] For example, assuming that the number of cells in the second cell list is recorded as F1, and the second threshold corresponding to height 2 or height range 2 is N2. When the terminal is at height 2 or height range 2, if F1 is less than N2, the terminal does not trigger the measurement report, that is, the terminal does not send a measurement report. In this case, the terminal can continue to perform cell measurements, and if some cells meet the corresponding triggering events, these cells are added to the second cell list. Until the number of cells in the second cell list is greater than or equal to N2, the terminal can trigger the sending of a measurement report to the network device.

[0170] Of course, if a cell that meets the triggering event appears again, the terminal can continue to add the cell to the second cell list. If the terminal continues to determine that F1 is greater than or equal to N2, the sending of the measurement report is not triggered. However, if F1 is less than N2 due to some reasons and F1 is greater than or equal to N2 again, the terminal can trigger the measurement report again.

[0171] In the case where the terminal determines to trigger measurement reporting according to the second threshold, it can also be implemented in the following manner.

[0172] In a measurement reporting method provided in an embodiment of the present application, Figure 5 This is another interactive diagram of a measurement reporting method provided in an embodiment of the present application. Figure 5 As shown, the cell measurement process can be applied to Figure 1 In the communication scenario shown or other similar communication scenarios, the method may include the following steps:

[0173] S501, the network device sends configuration information to the terminal.

[0174] In some embodiments, the configuration information includes at least one state information and at least one threshold value. Any state information corresponds to a threshold value. The at least one state information may include first state information and second state information. Of course, the at least one state information may also include other state information, such as third state information.

[0175] The first state information may correspond to a first threshold, the second state information may correspond to a second threshold, and the third state information may correspond to a third threshold.

[0176] It can be understood that the implementation process of S501 is similar to that of S301. For details, please refer to the description of each embodiment in S301, and this application will not go into details here.

[0177] S502: The terminal saves the cell identifiers in the first cell list.

[0178] In some embodiments, the terminal may save the cell identities of the cells included in the first cell list.

[0179] For example, the identifier may be an identity (ID) or an index.

[0180] Among them, when the state of the terminal is the second state, the cells in the triggered cell list of the terminal may also change. The first cell list is the triggered cell list of the terminal. For example, when the terminal meets the corresponding height or height range, the cells in the triggered cell list of the terminal may also change.

[0181] In some embodiments, the change of the cell in the triggering cell list may be a cell addition, a cell removal or a cell replacement, which is not limited in this application.

[0182] For example, when the terminal is in the second state, the cell identifiers of one or more cells in the first cell list may be saved. For example, when the terminal meets the corresponding height or height range, the terminal may save the cell identifiers of each cell in the first cell list.

[0183] It is understandable that S502 is an optional step, that is, S503 can be directly executed after S501, and the embodiment of the present application does not limit this. Moreover, the embodiment of the present application does not limit the execution order between S502 and S503.

[0184] S503: The terminal removes some or all of the cells in the first cell list.

[0185] In some embodiments, the terminal may remove some cells in the first cell list, or remove all cells in the first cell list.

[0186] For example, the terminal adds the cell that satisfies the triggering event to the triggering cell list to obtain the first cell list. When the terminal is in the second state, for example, when the terminal reaches the corresponding height or height range, some or all cells that already exist in the first cell list can be removed. In some examples, after removing some or all cells, the terminal can add the cell that satisfies the corresponding triggering event to the first cell list after removing some or all cells to obtain a new first cell list.

[0187] In some examples, the first cell list before the cell change can be referred to as the third cell list, and the new first cell list is still referred to as the first cell list.

[0188] In some embodiments, before a cell changes, or before a cell changes, may be before a portion of cells or all cells are removed.

[0189] In some embodiments, before a cell changes, or before a cell changes, may be before a new cell satisfying a triggering event is added.

[0190] In some embodiments, before a cell changes or before a cell changes may include before a portion of cells or all cells are removed, and before a new cell that meets a triggering event is added.

[0191] Adding a new cell that meets the triggering event may, for example, refer to performing cell measurement when the terminal is in the second state, and adding the cell that meets the triggering event to the first cell list.

[0192] It can be understood that the first cell list and the second cell list mentioned in the aforementioned embodiment are both represented as the triggered cell list of the terminal. The only difference is that for the convenience of description, the triggered cell list is called differently in different embodiments. There is no correlation between the first cell list and the second cell list mentioned in the aforementioned embodiment.

[0193] In some examples, when S502 is executed, since the saved cell identifier is the cell identifier of the cell in the first cell list before removing some or all cells, the saved cell identifier of the cell included in the first cell list can also be understood as the saved cell identifier of the cell included in the third cell list, which can be referred to as the cell identifier of the first cell. In other examples, the terminal can also refer to the cell identifier of the cell included in the new first cell list as the cell identifier of the second cell.

[0194] In some examples, the removal of cells can be executed before adding cells that meet the corresponding trigger event to the first cell list, or it can be executed synchronously during the process of adding cells that meet the corresponding trigger event to the first cell list. Of course, it can also be executed after adding cells that meet the corresponding trigger event to the first cell list, and the embodiments of the present application are not limited to this.

[0195] For example, when the terminal is in the second state, the terminal may save the cell identifiers of each cell in the first cell list. Afterwards, the terminal may remove some or all of the cells in the first cell list. Then, the cell measurement is performed again. During the cell measurement process performed by the terminal, the cell that meets the corresponding trigger event may be added to the first cell list to obtain a new first cell list.

[0196] For example, if the terminal meets the corresponding height or height range, the terminal can save the cell identifiers of each cell in the first cell list and remove some or all cells in the first cell list. The terminal can continue to perform cell measurement and add cells that meet the corresponding trigger event to the first cell list.

[0197] S504: The terminal performs measurement reporting according to the second threshold.

[0198] In some embodiments, the terminal may determine whether to trigger measurement reporting according to the second threshold.

[0199] For example, the terminal may determine to trigger the measurement report or determine not to trigger the measurement report according to the relationship between the number of cells in the new first cell list and the second threshold.

[0200] For example, when the terminal reaches the corresponding height or height range, it determines the second threshold corresponding to the height or height range. The terminal removes some or all cells in the first cell list, and triggers measurement reporting based on the relationship between the number of cells in the new first cell list and the second threshold. Alternatively, the terminal does not trigger measurement reporting based on the relationship between the number of cells in the new first cell list and the second threshold. It can be understood that the new first cell list may also include cells that meet the triggering event obtained by new measurement.

[0201] In some embodiments, when the terminal is in the second state, the second threshold value may be determined according to the configuration information. The terminal may perform measurement reporting based on the relationship between the current first cell list and the second threshold value. Among them, the current first cell list of the terminal may be a first cell list without removing cells. In this case, the terminal may also add cells that meet the triggering event to the first cell list. In other words, the first cell list of the terminal may not remove cells, and may also add new cells. The terminal may perform measurement reporting based on such a first cell list and the second threshold value.

[0202] This application can save the cell identifiers in the first cell list, and the terminal can also remove some or all cells in the first cell list, so that the terminal can accurately report the cells that meet the triggering event measured by the terminal, thereby improving the accuracy of cell measurement.

[0203] In a measurement reporting method provided in an embodiment of the present application, when the number of cells in the first cell list is greater than or equal to a second threshold, a measurement report is sent to a network device.

[0204] In some embodiments, when the number of cells in the new first cell list is greater than or equal to the second threshold, the terminal may trigger a measurement report. That is, the terminal may send a measurement report to the network device. In this case, the measurement report may include measurement results of one or more cells in the current first cell list. For example, the measurement report may include measurement results of each cell in the current first cell list.

[0205] The current first cell list may include cells that have not been removed by the terminal, and may also include cells that meet the corresponding triggering event and are newly measured by the terminal.

[0206] In some embodiments, the terminal may determine to send the measurement report based on the number of cells in the new first cell list being greater than or equal to the second threshold, and the number of cells in the third cell list being greater than or equal to the first threshold.

[0207] For example, assuming that the first threshold is N1, the second threshold is N2, the number of cells in the third cell list is recorded as F1, and the number of cells in the new first cell list is recorded as F2. When the terminal is in the second state, it is assumed that the second state information corresponding to the second state is associated with the second threshold. The second state may be to meet a certain height or a certain height range. If F2 is greater than or equal to N2, and F1 is greater than or equal to N1, the terminal can determine to send a measurement report to the network device. In some examples, consider the case where N1 is less than N2. For example, assuming that N1 is 3, N2 is 6, F1 is 3, and F2 is 6. Then when the terminal is in the first state, since F1 is greater than or equal to N1, it is considered that the measurement report has been performed, that is, the measurement results of the three cells corresponding to F1 are reported to the network device. When the terminal is in the second state, the number of cells in the triggering cell list becomes F2. But obviously at least three cells in F2 have not been reported by the terminal before. Then the terminal can trigger the measurement report. So that the measurement results corresponding to these cells can also be reported to the network device in a timely manner.

[0208] Of course, in this example, the new first cell list may also replace the first cell list of cells that have not been removed. That is, the first cell list in this example may not remove cells. For example, when the terminal is in the second state, if F1 is greater than or equal to N2, and F1 is greater than or equal to N1, the terminal may determine to send a measurement report to the network device. The implementation process is the same as the above example, and will not be repeated here for the convenience of description.

[0209] Obviously, compared with the situation in the related art where measurement reporting is not triggered according to the second threshold, triggering measurement reporting when the second threshold is met can avoid underreporting of some cells.

[0210] The present application can trigger measurement reporting when the number of cells in the first cell list is greater than or equal to the second threshold, so that the terminal can promptly report the cells that meet the triggering event measured in the second state, thereby improving the accuracy of cell measurement.

[0211] In a measurement reporting method provided in an embodiment of the present application, when the cells in the first cell list are different from the cells in the third cell list, a measurement report is sent to a network device.

[0212] In some embodiments, when the terminal is in the second state, when the number of cells in the first cell list is greater than or equal to the second threshold, and the cells in the first cell list are different from the cells in the third cell list, the terminal may trigger a measurement report. That is, the terminal may send a measurement report to the network device. In this case, the measurement report may include measurement results of one or more cells in the current first cell list. For example, the measurement report may include measurement results of each cell in the current first cell list.

[0213] It can be understood that the first cell list in this example should be understood as a new first cell list, that is, the first cell list after some or all cells are removed.

[0214] For example, the terminal meets the corresponding height or height range, and the height or height range corresponds to the second threshold. When the terminal determines that the number of cells in the first cell list is greater than or equal to the second threshold, the terminal can determine whether the cells in the first cell list are the same as the cells in the third cell list through the saved cell identifiers. It can be understood that since the third cell list is the first cell list before removing some cells or all cells, the cell identifiers of the first cell list saved by the terminal can also be considered as the cell identifiers of each cell in the third cell list.

[0215] For example, according to the cell identifier of the first cell and the cell identifier of the second cell mentioned in the embodiment of S503, the terminal can determine whether the cell in the first cell list is the same as the cell in the third cell list by comparing whether the cell identifier of the first cell and the cell identifier of the second cell are the same.

[0216] For example, if there is at least one cell only in the first cell list or the third cell list, it can be considered that the cells in the first cell list are different from the cells in the third cell list. Of course, it is also possible that only when the cells in the first cell list are completely different from the cells in the third cell list, the cells in the first cell list are considered different from the cells in the third cell list. This embodiment of the present application does not limit this.

[0217] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0218] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. In some cases, the drone removes cells from the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11', the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22', the number of cells in the trigger cell list before removing some or all cells is X33', and the number of cells in the trigger cell list after removing some or all cells is X44.

[0219] In this case, the drone can remove some or all cells in the triggered cell list. Optionally, the drone saves the cell identifiers of the cells included in the triggered cell list before removing some or all cells. That is, the drone can remove some or all of the X33' cells in the triggered cell list, and the terminal can also save the cell identifiers of the X33' cells. When X44 is greater than or equal to N22', if the cells in the triggered cell list after removing some or all cells are inconsistent with the cells in the triggered cell list before removing some or all cells, the measurement report is triggered.

[0220] like Figure 6 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding number of triggered cells N11' is 3; when the drone is at altitude 2 or altitude range 2, the corresponding number of triggered cells N22' is 4; the number of cells X33' in the third cell list is 3, namely cell 1, cell 2 and cell 3; the number of cells X44 in the first cell list is 4, namely cell 1, cell 3, cell 4 and cell 5. In this case, X44 is equal to N22', and the cells in the triggered cell list after removing some or all cells are inconsistent with the cells in the triggered cell list before removing some or all cells, the drone can trigger measurement reporting.

[0221] In other examples, if it is assumed that when the drone is at altitude 1 or altitude range 1, the corresponding number of triggered cells N11' is 3; when the drone is at altitude 2 or altitude range 2, the corresponding number of triggered cells N22' is 3; the number of cells X33' in the third cell list is 3, namely cell 1, cell 2 and cell 3; the number of cells X44 in the first cell list is 3, namely cell 1, cell 2 and cell 3. In this case, X44 is equal to N22', and the cells in the triggered cell list after removing some or all cells are consistent with the cells in the triggered cell list before removing some or all cells, the drone may not trigger measurement reporting.

[0222] The present application may also trigger measurement reporting when the number of cells in the first cell list is greater than or equal to the second threshold, and when the cells in the first cell list are different from the cells in the third cell list, so as to ensure that the terminal can timely report the measurement results of the new cells obtained by measurement, thereby improving the timeliness and accuracy of the cell measurement.

[0223] In a measurement reporting method provided in an embodiment of the present application, the measurement report includes measurement reports of different cells in the first cell list and the third cell list.

[0224] In some embodiments, the measurement report reported by the terminal to the network device may include the measurement results of each cell in the current first cell list. Then the measurement report may include the measurement results of the cells that meet the corresponding trigger event obtained by the terminal's new measurement. It can be understood that these cells will not appear in the third cell list because they are newly measured. Of course, the measurement report may also include the measurement results of cells that are repeated with the cells in the third cell list, which is not limited in the embodiments of the present application.

[0225] In some embodiments, the measurement report reported by the terminal to the network device may only include measurement reports of cells that are different from the first cell list and the third cell list. That is, the measurement report only includes measurement results of cells that meet the corresponding triggering event obtained by the terminal's new measurement. In this case, the measurement report does not include measurement results of cells that are repeated with cells in the third cell list.

[0226] It can be understood that in this case, the terminal may not report the measurement report of the same cell in the first cell list and the third cell list, so as to save signaling overhead.

[0227] The embodiment of the present application can timely report the measurement results of the newly measured cells that meet the triggering event to the network device. In some cases, it can also avoid repeated reporting of measurement results by some cells, reduce the redundancy of measurement reports, and reduce signaling overhead.

[0228] Of course, in some possible implementations, when the number of cells in the first cell list is less than the second threshold, measurement reporting may not be triggered.

[0229] In some embodiments, when the number of cells in the new first cell list is less than the second threshold, the terminal does not trigger measurement reporting. Alternatively, when the number of cells in the first cell list before removing the cell is less than the second threshold, the terminal does not trigger measurement reporting.

[0230] It can be understood that since the number of cells in the triggered cell list of the terminal does not meet the condition of being greater than or equal to the second threshold, that is, triggering the measurement report. In this case, the terminal can continue to perform cell measurements and add cells that meet the corresponding triggering event to the triggered cell list until the number of cells in the triggered cell list is greater than or equal to the second threshold, triggering the terminal to report the measurement report. The measurement report includes the measurement results of one or more cells in the current triggered cell list. For example, the measurement report includes the measurement results of each cell in the current triggered cell list. Of course, if a cell that meets the triggering event appears again, the terminal can continue to add the cell to the triggered cell list. In the case where the terminal continues to determine that the number of cells in the triggered cell list is greater than or equal to the second threshold, the sending of the measurement report is not triggered. However, in the case where the number of cells in the triggered cell list is less than the second threshold due to some reasons, and the number of cells in the triggered cell list is greater than or equal to the second threshold again, the terminal can trigger the measurement report again.

[0231] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0232] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. In some cases, the drone removes cells from the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11', the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22', the number of cells in the trigger cell list before removing some or all cells is X33', and the number of cells in the trigger cell list after removing some or all cells is X44.

[0233] like Figure 6 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding number of triggered cells N11' is 3; when the drone is at altitude 2 or altitude range 2, the corresponding number of triggered cells N22' is 5; the number of cells X33' in the third cell list is 3, namely cell 1, cell 2 and cell 3; the number of cells X44 in the first cell list is 4, namely cell 1, cell 3, cell 4 and cell 5. In this case, X44 is less than N22', and the drone continues to perform cell measurement. For cells that meet the trigger event, the drone can be added to the first cell list. And further determine whether the number of cells in the first cell list to which the new cell is added is greater than or equal to N22'. Until the number of cells in the first cell list is greater than or equal to N22', the drone can trigger the measurement report.

[0234] In some other possible implementations, when the terminal is in the second state, if the number of cells in the new first cell list is greater than or equal to the second threshold, or the number of cells in the first cell list before the cell is removed is greater than or equal to the second threshold, the terminal does not trigger measurement reporting.

[0235] It can be understood that in this case, since the number of cells in the triggered cell list of the terminal has satisfied the condition that the number of cells is greater than or equal to the second threshold. For cells that meet the corresponding triggering event, they can continue to be added to the triggered cell list. In the case where the number of cells in the triggered cell list is continuously greater than or equal to the second threshold, the sending of the measurement report is not triggered. However, in the case where the number of cells in the triggered cell list is less than the second threshold due to some reasons, and the number of cells in the triggered cell list is greater than or equal to the second threshold again, the terminal can trigger the measurement report again.

[0236] In some more specific embodiments, the terminal is described as a drone and the network device is described as a base station.

[0237] For example, the base station can configure one or more groups of trigger cell numbers based on altitude or altitude range for the drone. When the drone is at altitude 2 or altitude range 2, the drone can determine the number of trigger cells corresponding to altitude 2 or altitude range 2. In some cases, the drone removes cells from the trigger cell list. Assume that the number of trigger cells corresponding to altitude 1 or altitude range 1 is N11', the number of trigger cells corresponding to altitude 2 or altitude range 2 is N22', the number of cells in the trigger cell list before removing some or all cells is X33', and the number of cells in the trigger cell list after removing some or all cells is X44.

[0238] like Figure 6 As shown, assuming that when the drone is at altitude 1 or altitude range 1, the corresponding trigger cell number N11' is 3; when the drone is at altitude 2 or altitude range 2, the corresponding trigger cell number N22' is 4; the number of cells in the third cell list X33' is 3, namely cell 1, cell 2 and cell 3; the number of cells in the first cell list X44 is 4, namely cell 1, cell 3, cell 4 and cell 5. In this case, X44 is equal to N22', and the drone continues to perform cell measurement. For cells that meet the trigger event, the drone can be added to the first cell list, but the drone can trigger the measurement report.

[0239] In one or more embodiments provided above, one of the at least one status information includes at least one of the flight altitude information of the terminal, the moving speed information of the terminal, or the location area information where the terminal is located.

[0247] The present application provides multiple possible representations of status information so that the terminal can determine whether to trigger measurement reporting based on thresholds corresponding to one or more status information, thereby improving universality.

[0248] Figure 7 A schematic diagram of interaction of yet another measurement reporting method provided in an embodiment of the present application.

[0249] like Figure 7 As shown, the cell measurement process can be applied to Figure 1 In the communication scenario shown, the method may include the following steps:

[0250] S701, a network device generates configuration information.

[0251] In some embodiments, the network device may generate configuration information. The configuration information may include at least one state information and at least one threshold value.

[0252] The at least one state information may include first state information and second state information. Optionally, the at least one state information may also include at least one third state information. The at least one threshold may include a first threshold and a second threshold. Optionally, the at least one threshold may also include at least one third threshold.

[0253] For example, the network device determines the first state information and the first threshold value; and / or, the second state information and the second threshold value; and / or, the third state information and the third threshold value. The network device generates configuration information based on the determined state information and the corresponding threshold value. It is understandable that each third state information corresponds to a third threshold value. The threshold values ​​corresponding to different state information may be the same or different, which is not limited in the embodiments of the present application.

[0258] In some embodiments, for the above Figure 3 , Figure 5 and Figure 7 In each embodiment of the method shown, before the terminal meets the second state, the terminal may be in the first state. For example, the terminal switches from the first state to the second state.

[0259] It is worth noting that in the above embodiments, different status information may correspond to the same threshold or different thresholds, which is not limited in the embodiments of the present application.
