Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0002] The network device may configure some configuration information for the terminal device, such as measurement report configuration information, so that the terminal device can execute corresponding measurement events and report corresponding measurement reports to the network device when a trigger condition is met according to the measurement report configuration information.

[0003] For example, in one possible implementation, the H1 event can be represented as when the drone's altitude in the air is greater than threshold A, the drone executes a measurement event, such as measuring signal quality, and reports a measurement report corresponding to the measurement event to the network device; the H2 event can be represented as when the drone's altitude in the air is less than threshold B, the drone executes a measurement event, and reports a measurement report corresponding to the measurement event to the network device.

[0004] In the case where the network configuration configures multiple measurement events for the drone, for example, the network device configures multiple H1 events and / or multiple H2 events for the drone, if the drone is at a certain height A when it accesses the network or the network device reconfigures the H1 event and / or H2 event for the drone at a certain height A, if the height A is greater than the threshold corresponding to the multiple H1 events, or the height A is less than the threshold corresponding to the multiple H2 events. If the height A meets the threshold corresponding to the multiple measurement events, the drone will be triggered to execute multiple measurement events and report multiple measurement reports to the network device, causing the drone to repeatedly report measurement reports, which brings additional signaling overhead.

[0005] Therefore, how to avoid the situation where drones repeatedly report measurement reports becomes a problem that needs to be solved. Summary of the invention

[0006] The present application provides a communication method and a communication device to avoid the situation where a drone repeatedly reports measurement reports.

[0007] In a first aspect, a communication method is provided, which is applied to a terminal device, and the method includes: receiving first configuration information from a network device, the first configuration information including M first measurement events, the first measurement event including a first measurement result and a first threshold; when it is determined that the first measurement result meets the triggering conditions of N first measurement events among the M first measurement events, sending K first measurement reports, the K first measurement reports being measurement reports corresponding to K first measurement events among the N first measurement events, wherein N is greater than or equal to 2, and K is less than or equal to 2; optionally, when K is equal to 2, the N first measurement events include different types of measurement events, and N is greater than or equal to 3, and the K first measurement reports are measurement reports corresponding to the different types of measurement events.

[0008] Optionally, the terminal device may also send K first measurement reports when the first measurement result meets the triggering conditions of N first measurement events among the M first measurement events, without the need for a determination action.

[0009] Based on the embodiment of the present application, when the first measurement result meets the triggering conditions of N first measurement events among M first measurement events, the terminal device sends a measurement report corresponding to one of the measurement events or a measurement report of each type to the network device, thereby avoiding the terminal device from repeatedly sending measurement reports to the network device and saving signaling overhead.

[0010] In one implementation, when K=1, sending K first measurement reports includes: obtaining N measurement reports corresponding to the N first measurement events, wherein each first measurement event corresponds to a measurement report; and sending a first measurement report corresponding to a first trigger condition satisfied by the first measurement result in the N measurement reports, wherein the first trigger condition is one of the trigger conditions satisfied by the N first measurement events.

[0011] Based on the embodiments of the present application, although the terminal device measures multiple measurement reports, it only needs to select one to report to the network device, thereby avoiding repeated reporting of multiple measurement reports and saving signaling overhead.

[0012] In one implementation, when K=1, sending K first measurement reports includes: obtaining the first measurement report corresponding to a first trigger condition satisfied by the first measurement result, where the first trigger condition is one of the trigger conditions satisfied by the N first measurement events; and sending a first measurement report corresponding to the first trigger condition satisfied by the first measurement result.

[0013] Based on the embodiments of the present application, the terminal device only needs to execute one measurement event and send a measurement report of the measurement event to the network device, thereby avoiding repeated reporting of multiple measurement reports and saving signaling overhead.

[0026] Based on the embodiment of the present application, when the terminal device determines that the first measurement result (such as height) meets the first threshold and the second measurement result (such as signal strength) meets the second threshold, the terminal device sends a measurement report to the network device. This technical solution can enable the terminal device to adjust the threshold of the measurement event according to the height, so as to adapt to the different signal strengths received by the terminal device at different heights in practice.

[0131] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0132] First, in this application, "used for indication" may include being used for direct indication and being used for indirect indication. When describing that a certain indication information is used for indicating A, it may include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must carry A.

[0133] The information indicated by the indication information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each piece of information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0134] Second, "at least one" shown in the present application refers to one or more, and "multiple" refers to two or more. In addition, in the embodiments of the present application, "first", "second" and various digital numbers (for example, "1", "2", etc.) are only for the convenience of description, and are not used to limit the scope of the embodiments of the present application. The size of the sequence number of each process below does not mean the order of execution, and the execution order of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application, and it should be understood that the objects described in this way can be interchanged where appropriate, so that the schemes other than the embodiments of the present application can be described.

[0135] Third, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0136] Fourth, in the implementation of this application, "protocol" may refer to a standard protocol in the communication field, for example, it may include the NR protocol and related protocols used in future communication systems, and this application does not limit this.

[0137] Fifth, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0138] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0139] Figure 1 A schematic diagram of a communication system provided in an embodiment of the present application. Figure 1 As shown, the communication system may include one or more terminal devices and one or more network devices.

[0140] Among them, the terminal device can communicate with one or more network devices. The terminal device can be an aerial terminal device, which can fly above the network device and can be connected to the network device through an air interface (Uu interface). In this case, the terminal device mainly communicates with the network device in line of sight. When the flight altitude of the terminal device is different, the number of network devices that can communicate is different. Similarly, the signal strength or signal quality that can be obtained is also different.

[0141] Exemplarily, the terminal device in the embodiments of the present application may be an aerial vehicle, such as a drone, an unmanned spacecraft, etc.

[0142] Exemplarily, the network device in the embodiment of the present application may be an access network device, and the access network device may be any device with wireless transceiver function. The device includes but is not limited to: evolved Node B (eNB), next generation eNB (ng-eNB) connected to the 5th generation core network (5GC), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved node B, or homeNode B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TP) It can also be a gNB or transmission point (TRP or TP) in a 5G (such as a new radio (NR)) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or it can also be a network node constituting a gNB or transmission point, such as a distributed unit (DU), a centralized unit (CU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately or included in the same network element.

[0143] For example, in different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are used as examples for description in this application.

[0144] The network device may configure some configuration information for the terminal device, such as measurement report configuration information, so that the terminal device can execute corresponding measurement events and report corresponding measurement reports to the network device when a trigger condition is met according to the measurement report configuration information.

[0145] For example, for some common terminal devices, such as non-air terminal devices, the measurement events configured by the network device may mainly include A1, A2, A3, A4, A5, etc.

[0146] Among them, for the A1 event, it can be expressed as when the signal strength of the service cell of the terminal device is greater than the threshold value A1, the terminal device can report a measurement report including the signal strength of the service cell measured by it to the network device. The network device can make the terminal device shut down the measurement of some cells based on the measurement report 1. For the A2 event, it can be expressed as when the signal strength of the service cell of the terminal device is less than the threshold value A2, the terminal device can report a measurement report including the signal strength of the service cell measured by it to the network device, and the terminal device can switch the service cell of the terminal device based on the measurement report. For the A3 event, it can be expressed as when the signal strength of the cell adjacent to the service cell of the terminal device (or neighboring cell) is greater than the signal strength of the service cell of the terminal device, the terminal device can report a measurement report including the signal strength of the neighboring cell to the network, and the network device can decide whether to switch the terminal device to the neighboring cell based on the measurement report. For the A4 event, it can be expressed as when the signal strength of the neighboring cell is greater than the threshold value A4, the terminal device can report a measurement report including the signal strength of the neighboring cell to the network device. For the A5 event, it can be represented that when the signal strength of the service cell of the terminal device is less than the threshold A5 and the signal strength of the neighboring cell is greater than the threshold A6, the terminal device can report a measurement report including the signal strength of the service cell and the neighboring cell to the network device.

[0147] The embodiment of the present application is explained by taking the terminal device as a drone as an example. For example, for a drone, the measurement events configured by the network device for it can mainly include H1 events and H2 events. Among them, in one possible implementation method, the H1 event can be expressed as when the drone's altitude in the air is greater than the threshold A, the drone executes a measurement event, such as measuring the signal quality, and reports the measurement report corresponding to the measurement event to the network device; the H2 event can be expressed as when the drone's altitude in the air is less than the threshold B, the drone executes a measurement event, such as measuring the signal quality, and reports the measurement report corresponding to the measurement event to the network device; in this way, the network device can learn about the current situation of the drone based on the measurement report reported by the drone, and the network device can also make some further decisions, such as switching the drone's service cell.

[0148] For H1 events, the entry conditions are:

[0149] Ms–Hys>Thresh+Offset.

[0150] The conditions for leaving are:

[0151] Ms+Hys <Thresh+Offset。

[0152] Here, Ms represents the altitude of the terminal device in the air, for example, the Ms can be expressed in meters.

[0153] Hys represents the hysteresis value of the second measurement time, and may also be referred to as a hysteresis parameter.

[0154] Thresh represents threshold A, which represents the reference threshold parameter of H1 event.

[0155] Offset represents the offset value of threshold A. By adding the offset value to threshold A, the absolute threshold of the H1 event can be determined.

[0156] It should be understood that the entry condition of the H1 event can be understood as the condition for triggering the execution of the H1 event. When the above parameters meet the entry condition, the drone can be triggered to execute the H1 event and report the measurement report corresponding to the H1 event.

[0157] The departure condition of the H1 event can be understood as when the above parameters meet the departure condition, the triggering condition of the H1 event is not met, and the drone does not need to execute the H1 event.

[0158] For the H2 event, the entry conditions are:

[0159] Ms+Hys <Thresh+Offset。

[0160] The conditions for leaving are:

[0161] Ms–Hys>Thresh+Offset.

[0162] Here, Thresh represents threshold B, which represents the reference threshold parameter of H2 event. The remaining parameters have the same meanings as the above parameters and will not be described here.

[0163] In another possible implementation, the H1 event can be represented as when the drone's altitude becomes greater than threshold A, the drone executes a measurement event, such as measuring signal quality, and reports a measurement report corresponding to the measurement event to the network device; the H2 event can be represented as when the drone's altitude becomes less than threshold B, the drone executes a measurement event, such as measuring signal quality, and reports a measurement report corresponding to the measurement event to the network device.

[0164] In this case, the altitude of the drone needs to change to trigger the H1 event and / or H2 event. For example, the H1 event can be expressed as when the altitude of the drone becomes greater than threshold A, the drone executes the measurement event and reports the corresponding measurement report. For the H2 event, it can be expressed as when the altitude of the drone becomes less than threshold B, the drone executes the measurement event and reports the corresponding measurement report.

[0165] In addition, network devices can configure multiple H1 events and / or multiple H2 events for the drone. For multiple H1 events or H2 events, the threshold corresponding to each event is different.

[0166] See also Figure 2 , Figure 2 It is a schematic diagram of different thresholds corresponding to multiple measurement events.

[0167] Exemplarily, the network device may configure multiple H1 events for the drone. For example, the network device may configure a first H1 event, a second H1 event, and a third H1 event for the drone.

[0168] For example, the network device may send configuration information 1 to the drone, and the configuration information 1 may include a first H1 event, and the threshold corresponding to the first H1 event is 100 meters. When the altitude of the drone is greater than 100 meters, the first H1 event may be executed, and a corresponding measurement report may be sent to the network device.

[0169] The network device may send configuration information 2 to the drone, and the configuration information 2 may include a second H1 event, and the threshold corresponding to the second H1 event is 200 meters. When the altitude of the drone is greater than 200 meters, the second H1 event may be executed, and a corresponding measurement report may be sent to the network device.

[0170] The network device may send configuration information 3 to the drone, and the configuration information 3 may include a third H1 event, and the threshold corresponding to the third H1 event is 300 meters. When the altitude of the drone is greater than 300 meters, the third H1 event may be executed, and a corresponding measurement report may be sent to the network device.

[0171] The measurement report may be a signal strength, for example, the signal strength may be the signal strength of a serving cell of the terminal device, or the signal strength of a neighboring cell of the serving cell of the terminal device, or the signal strength may be the signal strength of a cell detected by the terminal device.

[0172] The measurement report may also be the height of the terminal device, or the measurement report may be other content, which is not limited in the embodiments of the present application.

[0173] It is understandable that when the network device configures multiple H2 events for the drone, the process is similar.

[0174] In the case where the network configuration has configured multiple measurement events for the drone, for example, the network device has configured multiple H1 events and / or multiple H2 events for the drone, if the drone is at a certain altitude A when it accesses the network or the network device reconfigures the H1 event and / or H2 event for the drone at a certain altitude A, in some possible implementations, if the altitude A is greater than the threshold corresponding to multiple H1 events, or the altitude A is less than the threshold corresponding to multiple H2 events, then the altitude A meets the threshold corresponding to multiple measurement events, which will trigger the drone to execute multiple measurement events and report multiple measurement reports to the network device, causing the drone to repeatedly report measurement reports, resulting in additional signaling overhead.

[0175] In view of this, an embodiment of the present application provides a communication method to avoid the situation where a drone repeatedly reports measurement reports.

[0176] Figure 3 is a schematic interaction diagram of a communication method provided in an embodiment of the present application. Figure 3 As shown, the method 300 may include steps 310 to 330 .

[0177] 310. The network device sends first configuration information to the terminal device, where the first configuration information includes M first measurement events, and the first measurement event includes a first threshold. Correspondingly, the terminal device receives the first configuration information.

[0178] The M first measurement events may be the M H1 events mentioned above, or the M first measurement events may be the M H2 events mentioned above, or the M first measurement events may also be the M H1 events and H2 events mentioned above.

[0179] Each first measurement event may correspond to a first threshold. For an H1 event, when the first measurement result is greater than the first threshold, it can be understood that the first measurement result satisfies the triggering condition of the H1 event. For an H2 event, when the first measurement result is less than the first threshold, it can be understood that the first measurement result satisfies the triggering condition of the H2 event. It should be understood that the first configuration information may include but is not limited to one or a combination of at least two of radio resource control signaling (RRC), MAC layer signaling, and physical layer signaling.

[0180] 320. When the terminal device determines that the first measurement result satisfies the triggering conditions of N first measurement events among the M first measurement events, the terminal device sends a first measurement report to the network device, where the first measurement report includes a measurement report corresponding to a target first measurement event among the N first measurement events, where N is greater than or equal to 2. Accordingly, the network device receives the first measurement report.

[0181] The target first measurement event may be one first measurement event, or may be a plurality of first measurement events less than N.

[0182] The first measurement result may be altitude information. For example, the first measurement result may be the altitude at which the terminal device is currently located.

[0183] It should be understood that the first measurement result may also be height difference information, for example, the first measurement result may be the height difference of the terminal device within a preset time (eg, unit time). The first measurement result may also be other content.

[0184] Exemplarily, the first measurement report may include signal strength. For example, the signal strength may be the signal strength of the serving cell of the terminal device, or the signal strength of a neighboring cell of the serving cell of the terminal device, or the signal strength may be the signal strength of a detected cell of the terminal device.

[0185] The first measurement report may also include the height of the terminal device, or the first measurement report may also include other content, which is not limited in the embodiment of the present application.

[0186] Optionally, when determining that the first measurement result satisfies the triggering condition of N first measurement events among the M first measurement events, the terminal device sends K first measurement reports to the network device, where the K first measurement reports are measurement reports corresponding to K first measurement events among the N first measurement events, where N is greater than or equal to 2, and K is less than or equal to 2;

[0187] Optionally, when K is equal to 2, the N first measurement events include measurement events of different types. Optionally, and N is greater than or equal to 3, the K first measurement reports are measurement reports corresponding to measurement events of different types.

[0188] Exemplarily, when K=1, when the terminal device determines that the first measurement result satisfies the triggering conditions of N first measurement events of M first measurement events, it sends a first measurement report to the network device. For example, the first measurement report may be a measurement report corresponding to one measurement event among the N first measurement events. In this way, the terminal device can report one measurement report to avoid repeatedly reporting multiple measurement reports.

[0189] In this case, the N first measurement events may be the N aforementioned H1 events, or the N aforementioned H2 events, or the N first measurement events may include both the aforementioned H1 events and the aforementioned H2 events.

[0190] In some examples where K=1, the terminal device determines that the first measurement result meets the triggering conditions of N first measurement events among M first measurement events, and sends K first measurement reports, including:

[0191] Obtaining N measurement reports corresponding to the N first measurement events, wherein each first measurement event corresponds to one measurement report;

[0192] A first measurement report corresponding to a first trigger condition satisfied by a first measurement result in the N measurement reports is sent, where the first trigger condition is one of the trigger conditions satisfied by the N first measurement events.

[0193] When the first measurement result satisfies the trigger conditions of N first measurement events, the terminal device can respectively execute the N first measurement events and obtain N measurement reports corresponding to the N first measurement events, after which the terminal device can select one measurement report from the N measurement reports and send it to the network device. For example, the terminal device can select a first measurement report corresponding to the first trigger condition among the multiple trigger conditions satisfied by the first measurement result and send it to the network device.

[0194] In this way, even though the terminal device measures multiple measurement reports, it only needs to select one to report to the network device, thereby avoiding repeated reporting of multiple measurement reports and saving signaling overhead.

[0195] In some other examples where K=1, the terminal device determines that the first measurement result satisfies the triggering conditions of N first measurement events among the M first measurement events, and sends K first measurement reports, including:

[0196] Obtaining a first measurement report corresponding to a first trigger condition satisfied by the first measurement result, where the first trigger condition is one of the trigger conditions satisfied by the N first measurement events;

[0197] A first measurement report corresponding to a first trigger condition satisfied by the first measurement result is sent.

[0198] When the first measurement result satisfies the triggering conditions of N first measurement events, the terminal device only needs to select one of the first measurement events without measuring other first measurement events, obtain the first measurement report of the first measurement event, and send the first measurement report to the network device. For example, the terminal device may select to execute the measurement event corresponding to the first triggering condition and send the measurement report of the measurement event.

[0199] In this way, the terminal device only needs to execute one measurement event and send a measurement report of the measurement event to the network device, thereby avoiding repeated reporting of multiple measurement reports and saving signaling overhead.

[0200] Exemplarily, when K=2, when the terminal device determines that the first measurement result satisfies the triggering conditions of N first measurement events of M first measurement events, it sends 2 first measurement reports to the network device. For example, the N first measurement events include both multiple H1 events and one or more H2 events, or the N first measurement events include both one or more H1 events and multiple H2 events, then the first measurement report can be a measurement report corresponding to one of the H1 events and a measurement report corresponding to one of the H2 events. In this way, the terminal device can report one measurement report of each type to avoid repeatedly reporting multiple measurement reports of one type of measurement event.

[0201] In some examples where K=2, when the terminal device determines that the first measurement result satisfies N first measurement events among M first measurement events, sending K first measurement reports includes:

[0202] Obtaining N measurement reports corresponding to the N first measurement events, wherein each first measurement event corresponds to one measurement report;

[0203] K first measurement reports corresponding to the first trigger condition satisfied by the first measurement result in the N measurement reports are sent, where the first trigger condition is one of the trigger conditions satisfied by each type of measurement events of different types.

[0204] When the first measurement result of the terminal device satisfies N first measurement events, in a scenario where the terminal device needs to send two first measurement reports, the terminal device can execute the N first measurement events respectively and obtain N measurement reports corresponding to the N first measurement events; thereafter, the terminal device can select one first measurement report from each type of measurement event and report two first measurement reports.

[0205] For example, if the N first measurement events include multiple H1 events and multiple H2 events, the terminal device may first obtain multiple measurement reports corresponding to the multiple H1 events and multiple measurement reports corresponding to the multiple H2 events; then, the terminal device selects one measurement report from the multiple measurement reports corresponding to the multiple H1 events and one measurement report from the multiple measurement reports corresponding to the multiple H2 events, and reports the two measurement reports to the network device. For example, the terminal device may select the first measurement report corresponding to the first trigger condition.

[0206] In this way, since the N first measurement events include different types of measurement events (such as H1 events, H2 events), for each type, the terminal device can report a measurement report to the network device, thereby avoiding repeated reporting of measurement reports for each type of measurement event.

[0207] In some other examples where K=2, the terminal device determines that the first measurement result satisfies N first measurement events among M first measurement events, and sends K first measurement reports, including:

[0208] Obtain K first measurement reports corresponding to a first trigger condition satisfied by the first measurement result, where the first trigger condition is one of the trigger conditions satisfied by each type of measurement event of different types;

[0209] K first measurement reports corresponding to the first trigger condition satisfied by the first measurement result are sent.

[0210] When the first measurement result of the terminal device satisfies N first measurement events, in a scenario where the terminal device needs to send two first measurement reports, the terminal device can select one measurement event of each type respectively, and obtain the corresponding first measurement report; and report one first measurement report of each type. For example, the terminal device can select the first trigger condition to correspond to the first measurement report.

[0211] For example, the N first measurement events include multiple H1 events and multiple H2 events. The terminal device can first select an H1 event corresponding to the multiple H1 events and an H2 event corresponding to the multiple H2 events, and respectively execute the corresponding measurement events to obtain two first measurement reports; thereafter, the terminal device reports the two measurement reports to the network device.

[0212] In this way, the terminal device only needs to execute one measurement event of each type and report one measurement report of each type, thereby avoiding repeated reporting of measurement reports of each type of measurement event.

[0213] Optionally, the terminal device may also send K first measurement reports when the first measurement result meets the triggering conditions of N first measurement events among M first measurement events, without the need for a determination action.

[0214] Exemplarily, the first trigger condition may include one of the following conditions:

[0215] A first threshold value that is closest to the flight height when the terminal device performs measurement among the N first threshold values ​​corresponding to the N first measurement events;

[0216] A maximum first threshold value among N first threshold values ​​corresponding to the N first measurement events;

[0217] The smallest first threshold value among the N first threshold values ​​corresponding to the N first measurement events;

[0218] The first threshold corresponding to the trigger condition with the earliest configuration time; or,

[0219] The first threshold corresponding to the trigger condition with the highest priority.

[0220] Optionally, the first trigger condition may also be the flight altitude when the terminal device receives the configuration information.

[0221] For example, N is 3, and the N first measurement events are three H1 events, namely H1 event 1, H1 event 2, and H1 event 3. Among them, the first threshold corresponding to H1 event 1 is 100 meters, and accordingly, the triggering condition of H1 event 1 is that the height of the terminal device is greater than 100 meters. The first threshold corresponding to H1 event 2 is 200 meters, and accordingly, the triggering condition of H1 event 2 is that the height of the terminal device is greater than 200 meters. The first threshold corresponding to H1 event 3 is 300 meters, and accordingly, the triggering condition of H1 event 3 is that the height of the terminal device is greater than 300 meters.

[0222] If the height of the terminal device is 320, the height satisfies the trigger conditions of three H1 events at the same time, then the terminal device can obtain three measurement reports corresponding to the three H1 events, and send the measurement report corresponding to the 300 meters closest to 320 meters to the network device; or, the terminal device sends the measurement report corresponding to the largest first threshold of 300 meters to the network device; or, the terminal device sends the measurement report corresponding to the smallest first threshold of 100 meters to the network device; or, if the first threshold corresponding to the trigger condition with the earliest configuration time of the network device is 100 meters, then the terminal device can send the measurement report corresponding to the first threshold of 100 meters corresponding to the trigger condition with the earliest configuration time to the network device; or, when configuring the above-mentioned first measurement event, the network device can also configure the priority of the first measurement event. If the first threshold corresponding to the trigger condition with the highest priority is 300 meters, the terminal device can send the measurement report corresponding to the trigger condition with the highest priority of 300 meters to the network device.

[0223] It is understandable that if the N first measurement events are N H2 events, the technical solution thereof can refer to the relevant description of the H1 event, and for the sake of brevity, it will not be repeated here.

[0224] In some embodiments, if the N first measurement events include both one or more H1 events and one or more H2 events, when the first measurement result (height) of the terminal device meets the triggering conditions of the N first measurement events, the terminal device may report the measurement report in the following ways.

[0225] Method 1: The terminal device reports a measurement report corresponding to one H1 event among one or more H1 events.

[0226] It should be understood that how the terminal device specifically reports the measurement report corresponding to the H1 event can be found in the relevant description in the above text.

[0227] Method 2: The terminal device reports a measurement report corresponding to one H2 event among one or more H2 events.

[0228] It should be understood that how the terminal device specifically reports the measurement report corresponding to the H2 event can be found in the relevant description in the above text.

[0229] Method three: The terminal device reports a measurement report corresponding to one H1 event among one or more H1 events and a measurement report corresponding to one H2 event among one or more H2 events.

[0230] It should be understood that how the terminal device specifically reports the measurement report corresponding to the H1 event, and how the terminal device specifically reports the measurement report corresponding to the H2 event can be found in the relevant description in the above text.

[0231] Optionally, the first measurement report may further include an identifier of a corresponding measurement event.

[0232] Optionally, the method may further include step 330. In some exemplary embodiments, step 330 may not be performed.

[0233] 330. The network device makes a decision according to the first measurement report.

[0234] For example, after receiving the first measurement report, the network device may switch the serving cell of the terminal device. Alternatively, after receiving the first measurement report, the network device may configure some new configuration information for the terminal device.

[0235] It should be understood that the embodiment of the present application does not limit the specific action performed by the network device after receiving the first measurement report. In other examples, after receiving the first measurement report, the network device can obtain the current situation of the terminal device, and at this time, the network device may not perform the task action.

[0236] Based on the embodiments of the present application, the network device can configure multiple measurement events for the terminal device. When the first measurement result meets the triggering conditions of N first measurement events among M first measurement events, the terminal device can send one measurement report or one measurement report of each type to the network device, thereby avoiding the terminal device from repeatedly sending measurement reports to the network device and saving signaling overhead of the terminal device and the network device.

[0237] In some embodiments, the first measurement report may also include the flight altitude of the terminal device when performing the measurement. For example, the first measurement report may include the above-mentioned first measurement result. This is conducive to the network device obtaining the current situation of the terminal device.

[0238] In some embodiments, the first measurement event further includes one or more second thresholds, wherein:

[0239] The terminal device sends K first measurement reports, including:

[0240] When it is determined that the first measurement result satisfies the N first thresholds corresponding to the N first measurement events, and the one or more second measurement results satisfy the second threshold, K first measurement reports are sent.

[0241] Exemplarily, the second measurement result may be signal strength or signal quality, etc.

[0242] When it is determined that the first measurement result (such as height) satisfies N first thresholds corresponding to N first measurement events, and one or more second measurement results (such as signal strength) satisfies the corresponding second thresholds, the terminal device can determine that the first measurement result satisfies the triggering conditions of N first measurement events out of M first measurement events, and send K first measurement reports to the network device.

[0243] Based on the embodiment of the present application, the terminal device needs to send a measurement report to the network device when the height meets the threshold and the signal strength meets the threshold. In this way, the terminal device can send a measurement report to the network device at the corresponding height. This technical solution can enable the terminal device to adjust the threshold of the measurement event according to the height, and adapt to the different signal strengths received by the terminal device at different heights in practice.

[0244] In some embodiments, the second measurement result is a signal strength, and one or more second measurement results satisfying a corresponding second threshold comprises one of the following:

[0245] The signal strength of the neighboring cell is greater than the signal strength of the serving cell of the terminal device;

[0246] The signal strength of the neighboring cell is greater than the first value; or,

[0247] The signal strength of the serving cell is less than the second value, and the signal strength of the neighboring cell is greater than the third value.

[0248] It should be understood that the neighboring cell may be a cell corresponding to the service cell of the terminal device.

[0249] The embodiment of the present application does not limit the specific values ​​of the first value, the second value, and the third value.

[0250] In some embodiments, before the terminal device sends K first measurement reports to the network device, the method may further include:

[0251] A first measurement configuration is applied, where the first measurement configuration includes a correspondence between a third threshold and the first information.

[0252] It should be understood that the first measurement configuration may be included in the first configuration information.

[0253] Exemplarily, the third threshold may be height information or height difference information, etc. The first information may include the number of triggered cells and / or the beam to be measured.

[0254] The corresponding relationship between the third threshold and the first information can be understood as the content of the corresponding first information under the third threshold.

[0255] For example, the third threshold is 100 meters, the corresponding number of trigger cells is 3, and / or the corresponding beam to be measured is beam 1; the third threshold is 200 meters, the corresponding number of trigger cells is 4, and / or the corresponding beam to be measured is beam 2. When the terminal device is at a height greater than 100 meters, the number of trigger cells applied is 3, and beam 1 is used to measure the signal strength when the conditions are met.

[0256] In some embodiments, when the first measurement configuration includes multiple third thresholds, the terminal device applying the first measurement configuration includes one of the following:

[0257] Applying first information corresponding to a third threshold value closest to the flight height when the terminal device performs measurement among multiple third threshold values;

[0258] Applying first information corresponding to the largest first threshold among a plurality of third thresholds;

[0259] Applying first information corresponding to the smallest first threshold among a plurality of third thresholds;

[0260] the first information corresponding to the third threshold value with the earliest configuration time; or,

[0261] The first information corresponding to the third threshold with the highest priority.

[0262] Based on the embodiments of the present application, the terminal device can determine the first information under the corresponding height threshold.

[0263] In some embodiments, the terminal device sends K first measurement reports, including:

[0264] When it is determined that the first measurement result satisfies the N first thresholds corresponding to the N first measurement events, and the number of cells in the triggering cell list is greater than or equal to the number of triggering cells, and / or,

[0265] When the first measurement result satisfies the N first thresholds corresponding to the N first measurement events, the beam to be measured is measured, and the K first measurement reports are sent.

[0266] It should be understood that the number of cells in the trigger cell list may be the number of cells that the terminal device can measure.

[0267] For example, when the number of triggered cells is 4, when the first measurement result meets N first thresholds (height thresholds), and the number of cells in the trigger cell list of the terminal device is greater than 4, it can be determined that the first measurement result meets the triggering conditions of N first measurement events among M first measurement events. At this time, the terminal device can report K first measurement reports to the network device. This can reduce signaling overhead.

[0268] For another example, the beam to be measured is beam 2, and the terminal device measures beam 2. When the first measurement result meets N first thresholds (height thresholds), the terminal device measures beam 2 and reports the first measurement report. In this way, the terminal device measures the beam to be measured when the height meets the threshold, and then reports the first measurement report, so that the terminal device can meet the needs of different communication environments at different heights.

[0269] In some embodiments, when the first measurement event is an H1 event, the first threshold for each H1 event may include one of the following:

[0270] The height threshold of the H1 event (threshold);

[0271] The sum of the height threshold of the H1 event and the hysteresis value, or the difference between the height threshold of the event H1 and the hysteresis value (Hysteresis);

[0272] The sum of the height threshold and the offset value corresponding to the H1 event; or,

[0273] The sum of the height threshold and the offset value for an H1 event plus the hysteresis value, or the sum of the height threshold and the offset value for an H1 event minus the hysteresis value.

[0274] In some embodiments, when the first measurement event is an H2 event, the first threshold for each H1 event may include one of the following:

[0275] H2 event height threshold (threshold);

[0276] The sum of the height threshold of the H2 event and the hysteresis value, or the difference between the height threshold of the event H2 and the hysteresis value (Hysteresis);

[0277] The sum of the height threshold corresponding to the H2 event and the offset value; or,

[0278] The sum of the height threshold and the offset value for H2 events plus the hysteresis value, or the sum of the height threshold and the offset value for H2 events minus the hysteresis value.

[0279] In some embodiments, the first configuration information also includes first indication information, and the first indication information is used to instruct the terminal device to determine the first trigger condition.

[0280] For example, the network device may configure the first indication information in ReportConfig or ReportConfigToAddModList. The first indication information may be carried in 1 bit of the first configuration information.

[0281] In some embodiments, the terminal device determines the first trigger condition, including:

[0282] If the N first measurement events are of the same type, it is determined, according to the first indication information, to use one of the trigger conditions satisfied by the N first measurement events as the first trigger condition.

[0283] Exemplarily, the N first measurement events are N H1 events, and the terminal device may determine, according to the first indication information, to use trigger condition 1 among the trigger conditions satisfied by the N H1 events as the first trigger condition.

[0284] For example, the first indication information instructs the terminal device to use the maximum altitude threshold among the altitude thresholds corresponding to multiple H1 events as the first trigger condition. Alternatively, the first indication information instructs the terminal device to use the minimum altitude threshold among the altitude thresholds corresponding to multiple H1 events as the first trigger condition. Alternatively, the first indication information instructs the terminal device to use the altitude threshold closest to the flight altitude when the terminal device performs measurement as the first trigger condition. Alternatively, multiple H1 events have different priorities (or the altitude thresholds corresponding to multiple H1 events have different priorities), and the first indication information may instruct the terminal device to use the altitude threshold with the highest priority as the first trigger condition. Alternatively, when the configuration times of multiple H1 events are different, the first indication information may instruct the terminal device to use the altitude threshold corresponding to the H1 event with the earliest configuration time as the first trigger condition.

[0285] Correspondingly, the N second measurement events may also be N H2 events. The manner in which the terminal device determines the first trigger condition according to the first indication information may refer to the relevant description in the foregoing text.

[0286] In some embodiments, the terminal device determines the first trigger condition, including:

[0287] If the N measurement events are first measurement events of different types, it is determined according to the first indication information to use one of the trigger conditions satisfied by the N first measurement events as the first trigger condition.

[0288] Exemplarily, the N measurement events include both one or more H1 events and one or more H2 events.

[0289] In one embodiment, the first indication information may indicate that the terminal device uses one of the trigger conditions satisfied in one or more H1 events as the first trigger condition. The specific result indicated by the first indication information may refer to the above description.

[0290] In another manner, the first indication information may instruct the terminal device to use one of the trigger conditions satisfied in one or more H2 events as the first trigger condition. The specific result indicated by the first indication information may refer to the above description.

[0291] In another embodiment, the first indication information may also instruct the terminal device to use one of the trigger conditions satisfied in one or more H1 events and one of the trigger conditions satisfied in one or more H2 events as the first trigger condition. For the H1 event or H2 event, the specific result indicated by the first indication information can be found in the description above.

[0292] In some optional embodiments, when multiple H1 events and / or multiple H2 events are configured in the first configuration information, the first configuration information may include the above-mentioned first indication information, so that the terminal device can report the measurement report of a specific measurement event according to the first indication information, avoid repeated reporting of the measurement report, and thus save signaling overhead.

[0293] It should be understood that in the absence of the first indication information, the terminal device can also determine the first trigger condition according to the above logic, and the embodiments of the present application are not limited to this.

[0294] In some embodiments, the first configuration information is initial configuration information or reconfiguration configuration information.

[0295] In this technical solution, when the first configuration information is the configuration information of the initial configuration or the configuration information of the reconfiguration, the terminal device can report a measurement report to the network device once, avoiding the situation where the measurement report is not reported to the network device.

[0296] In some embodiments, when the first configuration information is configuration information for the initial configuration or configuration information for the reconfiguration, and the terminal device has reported a first measurement report, when the terminal device determines that its height becomes greater than a threshold value C, it can execute measurement event C and report measurement report C of measurement event C to the network device; when the terminal device determines that its height becomes less than a threshold value D, it can execute measurement event D and report measurement report D of measurement event D to the network device.

[0297] It is understandable that the measurement event C and measurement event D are configured by the network device for the terminal device. When the network device is configured with multiple measurement events C and / or measurement events D, the terminal device can also select a measurement report of one of the measurement events to report according to the relevant description in the foregoing text, which will not be repeated here.

[0298] It should be understood that the specific description of the terminal device reporting the first measurement report in this embodiment can be found in the relevant description in the previous text, and for the sake of brevity, it will not be repeated here.

[0299] Optionally, the measurement report C or the measurement report D may also include the flight altitude at which the terminal device performs the measurement.

[0300] In some embodiments, the above-mentioned first indication information can also be used to instruct the terminal device to report measurement report C or measurement report D to the network device when conditions are met when the first configuration information is initial configuration information or reconfiguration configuration information and the terminal device has reported the first measurement report.

[0301] In some embodiments, the first configuration information may also include second indication information, and the second indication information is used to instruct the terminal device to determine that the first measurement result meets the triggering conditions of N first measurement events based on the relationship between the height difference information within a preset time and the first threshold.

[0302] For example, for an H1 event, when the height difference information within the preset time is greater than the corresponding first threshold, it can be determined that the first measurement result meets the trigger condition of the corresponding measurement event. For an H2 event, when the height difference information within the preset time is less than the corresponding first threshold, it can be determined that the first measurement result meets the trigger condition of the corresponding measurement event.

[0303] Exemplarily, the preset time is a unit time. The preset time may also be other values, such as 2 seconds or 3 seconds.

[0304] Exemplarily, the second indication information may be in a 1-bit byte in the first configuration information.

[0305] It should be understood that in some possible implementations, when the network device includes a CU-DU, step 310 may be specifically performed by the DU. For example, the CU may send the first configuration information to the DU, and the DU may specifically send the first configuration information to the terminal device.

[0306] For another example, the network device receives a first measurement report sent by the terminal device. Specifically, the DU may receive the first measurement report sent by the terminal device, and then the DU may send the first measurement report to the CU for processing and decision making.

[0307] For another example, step 330 may be performed by the CU.

[0308] In some cases, the network device may also configure a new measurement event for the terminal device, so that the terminal device sends a measurement report to the network device when the new measurement event meets the triggering condition. Figure 4 Introduce the technical solution.

[0309] Figure 4 is a schematic flow chart of a communication method provided in an embodiment of the present application. Figure 4 As shown, the method 400 may include steps 410 to 430 .

[0310] 410, the network device sends second configuration information to the terminal device, the second configuration information includes a target measurement event, and the target measurement event is a measurement event triggered according to the relationship between the height difference information and the threshold information. Correspondingly, the terminal device receives the second configuration information.

[0311] In some embodiments, the target measurement event may include a second measurement event and / or a third measurement event, wherein the second measurement event is a measurement event triggered when the height difference of the terminal device is greater than a first threshold, and the third measurement event is a measurement event triggered when the height difference of the terminal device is less than a second threshold.

[0312] The height difference information may be a difference between a first height and a second height of the terminal device, wherein the first height is the height of the terminal device at a first moment, and the second height is the height of the terminal device at a second moment.

[0313] For example, the first moment may be the moment at which the terminal device is currently located. Alternatively, the first moment is the moment at which the terminal device performs a measurement event, and accordingly, the first height is the height at which the terminal device is located when performing the measurement event.

[0314] The second moment may be a moment before the first moment, for example, the second moment may be a moment 1 second before the first moment, or a moment 5 seconds before the first moment.

[0315] Alternatively, the height difference may also be described as the height difference of the terminal device within a preset time. Alternatively, the height difference may also be the height difference of the terminal device within a unit time.

[0316] Taking the height difference as the height difference per unit time as an example, when the height difference is a positive value, it means that the terminal device is in the process of ascending and the height of the terminal device is constantly rising; when the height difference is a negative value, it means that the terminal device is in the process of descending and the height of the terminal device is constantly descending.

[0317] In some examples, the second configuration information may also include the second height, in which case the second height may be a fixed value, for example, 50 meters or 100 meters, etc. Alternatively, the second height may also be the height at which the terminal device receives the second configuration information, and the second height may also be referred to as the initial height.

[0318] The embodiment of the present application does not limit the specific value of the first threshold. For example, the first threshold may be 5 meters or 10 meters.

[0319] For the second measurement event and the third measurement event,

[0320] The entry conditions are:

[0321] Ms–Height-origin–Hys>Thresh+Offset; or,

[0322] |Ms–Height-origin–Hys|>Thresh+Offset; or,

[0323] |Ms–Height-origin|>Thresh;

[0324] Its departure condition is:

[0325] Ms–Height-origin-Hys<Thresh+Offset; or,

[0326] |Ms–Height-origin–Hys|<Thresh+Offset; or,

[0327] |Ms–Height-origin|<Thresh;

[0328] Wherein, Ms represents the air height of the terminal device, that is, the first height in the previous text. For example, Ms can be expressed in meters.

[0329] Height-origin represents the initial height of the terminal device, that is, the second height in the previous text.

[0330] Hys represents the hysteresis value of the second measurement event, which can also be called the hysteresis parameter.

[0331] Thresh represents the above threshold information. When Thresh is a positive value, that is, the above first threshold, it represents the situation where the terminal device rises. When Thresh is a negative value, that is, the above first threshold, it represents the situation where the terminal device descends.

[0332] Offset represents the offset value of the above threshold information.

[0333] It can be understood that when the second height is the height configured by the network device, that is, when the second configuration information includes the second height. Height-origin in the above formula can be denoted as Height-configured.

[0334] 420. When the target measurement event of the terminal device meets the trigger condition, the terminal device sends a measurement report of the target measurement event to the network device. Correspondingly, the network device receives the measurement report.

[0335] For the second measurement event, when the height difference of the terminal device is greater than the first threshold, it can be determined that the second measurement event meets the trigger condition, or when the height of the terminal device meets the entry condition of the second measurement event, the terminal device sends a measurement report of the second measurement event to the network device.

[0336] For the third measurement event, when the height difference of the terminal device is less than the second threshold, it can be determined that the third measurement event meets the trigger condition, or when the height of the terminal device meets the entry condition of the third measurement event, the terminal device sends a measurement report of the third measurement event to the network device.

[0337] Exemplarily, the measurement report may be a signal strength. For example, the signal strength may be the signal strength of a serving cell of the terminal device, or the signal strength of a neighboring cell of the serving cell of the terminal device, or the signal strength may be the signal strength of a cell detected by the terminal device.

[0338] The measurement report may also be the height of the terminal device, or the measurement report may be other content, which is not limited in the embodiments of the present application.

[0339] 430, the network device makes a decision based on the measurement report.

[0340] For example, after receiving the measurement report, the network device may switch the serving cell of the terminal device. Alternatively, after receiving the measurement report, the network device may configure some new configuration information for the terminal device.

[0341] It should be understood that the embodiment of the present application does not limit the specific actions performed by the network device after receiving the measurement report. In other examples, after receiving the measurement report, the network device can obtain the current situation of the terminal device, and at this time, the network device may not perform the task action.

[0342] It should be understood that step 430 is an optional step. In some embodiments, step 430 may not be performed.

[0343] Based on the embodiments of the present application, the network device can configure a measurement event for the terminal device so that the terminal device reports a measurement report when the conditions are met based on the relationship between the height difference information and the threshold information. This can avoid the situation where the terminal device repeatedly reports the measurement report when the conditions are met only based on the height and the threshold, thereby saving the signaling overhead of the terminal device and the network device.

[0344] It should be understood that in some possible implementations, when the network device includes a CU-DU, step 510 may be specifically performed by the DU. For example, the CU may send the second configuration information to the DU, and the DU may specifically send the second configuration information to the terminal device.

[0345] For another example, the network device receives a measurement report sent by the terminal device. Specifically, the DU may receive the measurement report sent by the terminal device. After that, the DU may send the measurement report to the CU, which processes and makes a decision.

[0346] For another example, step 530 may be performed by the CU.

[0347] In some embodiments, the target measurement event may also be combined with the above-mentioned A3 event, or A4 event, or A5 event.

[0348] In this case, the second measurement event can also be understood as the terminal device sending a measurement report to the network device when the height difference of the terminal device is greater than the first threshold and the signal strength information of the terminal device meets the second condition.

[0349] Correspondingly, the third measurement event can also be understood as the terminal device sending a measurement report to the network device when the height difference of the terminal device is less than the second threshold and the signal strength of the terminal device meets the second condition.

[0350] Exemplarily, the second condition may include one of the following conditions:

[0351] The signal strength of the neighboring cell of the terminal device is greater than the signal strength of the serving cell of the terminal device;

[0352] The signal strength of the neighboring cell of the terminal device is greater than the threshold;

[0353] The signal strength of the service cell of the terminal device is less than threshold 1, and the signal strength of the neighboring cell is greater than threshold 2.

[0354] In this case, the terminal device will send a measurement report to the network device only when the terminal device determines that the above two conditions are met. This technical solution enables the terminal device to adjust the threshold of the measurement event according to the height, so as to meet the different needs of the signal strength received by the terminal device at different heights in practice.

[0355] In some embodiments, the target measurement event may also be combined with first information, and the first information may include the number of triggered cells and / or the number of measurement beams.

[0356] In this technical solution, before sending the measurement report, the terminal device may also first apply the first measurement configuration, where the first measurement configuration includes a correspondence between the third threshold and the first information.

[0357] It can be understood that the first measurement configuration may be included in the first configuration information.

[0358] Exemplarily, the third threshold is a threshold of the height difference of the terminal device. When the first information is the number of triggered cells, the first measurement configuration may be a correspondence between the height difference threshold and the corresponding number of triggered cells.

[0359] In this case, the second measurement event can also be understood as the terminal device sending a measurement report to the network device when the height difference of the terminal device is greater than the first threshold and the number of cells in the trigger cell list is greater than or equal to the trigger cell number, thereby saving signaling overhead.

[0360] For example, the height difference threshold is the first threshold 1, and the corresponding number of triggering cells is 3; the height difference threshold is the first threshold 2, and the corresponding number of triggering cells is 4.

[0361] When the terminal device determines that the height difference is greater than the first threshold 1 and the number of cells in the triggering cell list is greater than 3, it sends a measurement report to the network device.

[0362] Correspondingly, the third measurement event can also be understood as the terminal device sending a measurement report to the network device when the height difference of the terminal device is less than the second threshold and the number of cells in the trigger cell list is greater than or equal to the trigger cell number.

[0363] It can be understood that the number of cells in the triggering cell list is the number of cells measured by the terminal device.

[0364] Correspondingly, when the height difference meets the threshold, when the number of cells in the trigger cell list is less than the number of trigger cells, the terminal device does not send a measurement report to the network device. In this way, the terminal device only needs to report a measurement report once when the condition is met, which can avoid the terminal device from reporting measurement reports frequently.

[0365] Exemplarily, the third threshold is a threshold of the height difference of the terminal device. When the first information is a beam to be measured, the first measurement configuration may be a correspondence between the height difference threshold and the corresponding beam to be measured.

[0366] In this case, the second measurement event can also be understood as the terminal device measuring the beam to be measured when the height difference of the terminal device is greater than the first threshold, and sending a measurement report to the network device, so that the terminal device can adapt to the requirements of different communication environments at different heights.

[0367] For example, the height difference threshold is the first threshold 1, and the corresponding beam to be measured is beam 1; the height difference threshold is the first threshold 2, and the corresponding beam to be measured is beam 2.

[0368] When the terminal device measures beam 1 and the height difference of the terminal device is greater than the first threshold 1, a measurement report is sent to the network device.

[0369] Correspondingly, the third measurement event can also be understood as the terminal device measuring the beam to be measured when the height difference of the terminal device is less than the second threshold, and sending a measurement report to the network device.

[0370] Exemplarily, when the third threshold is the height difference threshold and the first information is the number of trigger cells and the beam to be measured, the second measurement event can also be used to instruct the terminal device to measure the beam to be measured, and when the height difference of the terminal device is greater than the first threshold and the number of cells in the trigger cell list is greater than or equal to the number of trigger cells, a measurement report is sent to the network device.

[0371] The third measurement event can also be understood as the terminal device measuring the beam to be measured and sending a measurement report to the network device when the height difference of the terminal device is less than the second threshold and the number of cells in the trigger cell list is greater than or equal to the number of trigger cells.

[0372] In this way, the terminal device can report the measurement report to the network device when it is determined that multiple conditions are met. This technical solution can avoid the terminal device from frequently reporting the measurement report to the network device.

[0373] The current communication standards (such as R18) support the configuration of a dedicated aircraft to everything (A2X) resource pool for drones. Only A2X communication can be performed on this A2X dedicated resource pool, and other sidelink communications cannot be performed. At the same time, the current communication standards also support A2X communication on the ordinary vehicle to everything (V2X) communication resource pool. Therefore, if the network device connected to the drone is a network device that supports a lower version of the communication standard (such as R17 and below), the drone may not be able to determine whether A2X communication is possible.

[0374] Figure 5 is a schematic interaction diagram of a communication method provided in an embodiment of the present application. Figure 5 As shown, the method 500 may include steps 510 to 520 .

[0375] 510. The network device sends second information, where the second information includes the type of communication mode supported by the network device, where the type of communication mode includes the first communication mode and / or the second communication mode.

[0376] In some possible embodiments, the second information may be indication information for indicating the type of communication mode supported by the network device, and / or the second information may be configuration information of a resource pool of the communication mode supported by the network device.

[0377] Exemplarily, the first communication mode may be A2X, and the second communication mode may be V2X. It is understandable that the first communication mode and the second communication mode may also be other communication modes.

[0378] In some examples, when the second information is information indicating the communication mode supported by the network device, the second information may include information indicating A2X communication supported by the network device and / or information indicating V2X communication supported by the network device. For example, the indication information is carried in a 1-bit byte of the second information.

[0379] In other examples, when the second information includes configuration information of a resource pool for a communication mode supported by a network device, the configuration information may indicate an A2X-specific resource pool configuration and / or a V2X-specific resource pool configuration.

[0380] In other examples, the second information may also include both the above-mentioned indication information and corresponding configuration information.

[0381] Exemplarily, the second information may be sent by a network device in a broadcast or multicast manner, and the embodiment of the present application does not limit the specific manner in which the second information is sent.

[0382] In some possible implementations, when the network device includes a CU-DU, step 510 may be specifically performed by the DU. For example, the CU may send the second information to the DU, and the DU may specifically send the second information.

[0383] 520, the terminal device 1 communicates with other terminal devices using a target communication mode according to the second information, where the target communication mode is the first communication mode and / or the second communication mode.

[0384] In some optional embodiments, before step 520, the terminal device 1 may also first determine, based on the second information, that it can communicate with other terminal devices in the target communication manner.

[0385] In one example, if terminal device 1 determines based on the second information that the network device supports A2X communication and is configured with an A2X-dedicated resource pool, terminal device 1 can determine that it can perform A2X communication with other terminal devices in the A2X-dedicated resource pool, then terminal device 1 performs A2X communication with other terminal devices in the A2X-dedicated resource pool.

[0386] In one example, if the terminal device 1 determines based on the second information that the network device supports A2X communication, but the A2X-dedicated resource pool is not configured, it means that the network device is configured with a V2X-dedicated resource pool. The terminal device 1 can determine that it can perform A2X communication with other terminal devices in the V2X-dedicated resource pool. Then the terminal device 1 performs A2X communication with other terminal devices in the V2X-dedicated resource pool.

[0387] In one example, if the terminal device 1 determines according to the second information that the network device does not support A2X communication and no A2X-specific resource pool is configured, the terminal device 1 may determine that it cannot perform A2X communication with other terminal devices. In this case, the terminal device 1 may perform V2X communication with other terminal devices on the V2X resource pool.

[0388] In one example, if terminal device 1 determines based on the second information that the network device supports A2X and V2X communications, and resource pools for A2X and V2X are configured, terminal device 1 can perform A2X communication with other terminal devices on the A2X resource pool, and perform V2X communication with other terminal devices on the V2X resource pool.

[0389] Based on the embodiment of the present application, the network device can send second information to the terminal device for indicating the communication method supported by the network device, thereby facilitating the terminal device to determine the capabilities of the network device, so that the terminal device can determine whether it can perform A2X communication with other terminal devices, and determine to ultimately adopt the corresponding communication method to communicate with other terminal devices.
