[0002] The present disclosure relates to the field of communication technology, and in particular, to a method, device, storage medium and program product for managing measurement reporting event. BACKGROUND

[0003] In a mobile communication network, cell switching of a communication network can ensure that a user equipment (UE) is smoothly transferred from the coverage range (such as a cell) of one base station to the coverage range of another base station (i.e., handover) or between different sectors of the same base station (i.e., intra-cell handover) during movement.

[0004] Currently, in the implementation process of cell switching, the UE needs to measure the communication environment of the cell and the neighboring cell based on the measurement reporting event in the radio resource control (RRC) signaling issued by the base station, and report the measurement data to the base station, and then the base station instructs the UE to access the cell after switching based on the measurement data reported by the UE.

[0025] The technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0026] It should be noted that in the present disclosure, the words “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design scheme described as “exemplary” or “for example” in the present disclosure should not be interpreted as being more preferred or advantageous than other embodiments or design schemes. In fact, the use of the words “exemplary” or “for example” is intended to present concepts in a manner that is easy to understand by those skilled in the art.

[0027] Hereinafter, the terms “first”, “second”, and the like are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with “first”, “second”, and the like can explicitly or implicitly include one or more of the features.

[0028] In the description of the present disclosure, unless otherwise specified, “ / ” means “or”, for example, A / B can mean A or B. “And / or” in the present disclosure is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B can mean: only A, only B, and A and B. In addition, “at least one” means one or more, and “multiple” means two or more.

[0029] It can be understood that, without conflict, the functions, steps, and the like shown in the present disclosure can occur in an order different from that shown in the present disclosure, and there can be other functions, steps, and the like between any two adjacent functions, steps, and the like shown in the present disclosure.

[0030] In mobile communication network (2G, 3G, 4G or 5G), whether a terminal performs handover is determined by a base station according to a measurement report reported by a mobile device (terminal). The terminal has multiple measurement items (such as reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR), etc.) and multiple methods (such as periodicity, event triggering, etc.) to measure the signal quality of a serving cell and a neighboring cell. Ideally, the base station allows the terminal to report the signal quality of the serving cell and the neighboring cell, and triggers handover through a single measurement. However, in reality, frequent ping-pong handover can cause the base station to be overloaded. Therefore, in order to avoid the above situation, the 3rd generation partnership project (3GPP) specification proposes a set of measurement and reporting mechanisms, i.e., the measurement and reporting of traditional radio resource management.

[0031] These measurement and reporting types are called "events", and the "events" that the terminal must report are notified to the terminal by the base station through the RRC signaling message. The above events can include:

[0032] (1) A1 event (serving cell is higher than a threshold value);

[0033] (2) A2 event (serving cell is lower than a threshold value);

[0034] (3) A3 event (neighboring cell is higher than the offset of the primary serving cell);

[0035] (4) A4 event (neighboring cell is higher than a threshold value);

[0036] (5) A5 event (serving cell is lower than a threshold value 1, and neighboring cell is higher than a threshold value 2 of the serving cell);

[0037] (6) A6 event (neighboring cell is higher than the offset of the serving cell);

[0038] (7) B1 event (different system neighboring cell is higher than a threshold of the serving cell);

[0039] (8) B2 event (serving cell is lower than a threshold 1, and different system neighboring cell is higher than a threshold value 2).

[0040] A1 event (serving cell above threshold) is typically used to cancel an ongoing handover procedure. It can be triggered when a UE moves to the cell edge and starts a mobility procedure, but then moves back to a well-covered area before the mobility procedure is completed.

[0041] A2 event (serving cell below threshold) is typically used to trigger a UE to move to the cell edge for a mobility procedure. Event A2 does not involve any measurements of neighbor cells, it can be used to trigger any mobility procedure or to trigger measurements of neighbor cells; it can be used for a measurement-based mobility procedure. The base station can configure measurement gaps and inter- or inter- system measurements after event A2 is triggered. This means that inter- or inter- system measurements need to be done in case the coverage conditions are relatively poor and there is a high probability that a handover is needed.

[0042] A3 event (neighbor cell above offset from primary serving cell): is typically used for intra- or inter- frequency handover procedures. When event A2 is triggered, measurement gaps, measurement inter- frequency objects and event A3 for inter- frequency handover can be configured. Event A3 provides a handover trigger mechanism based on relative measurement results, e.g. it can be configured to trigger when a neighbor cell RSRP is stronger than a certain cell RSRP.

[0043] A4 event (neighbor cell above threshold): A4 event can be used for handover procedures that are not dependent on the coverage of the serving cell. For example, in a load balancing function, a UE is decided to be handed over from a serving cell due to load conditions rather than radio conditions. In this case, the UE only needs to detect that the target cell is better than a certain signal level and can provide sufficient coverage.

[0044] A5 event (serving cell below threshold 1, neighbor cell above threshold 2): A5 event is typically used for intra- or inter- frequency handover procedures. A UE that is configured for inter- frequency handover after event A2 is triggered can be configured with measurement gaps and event A5. Event A5 provides a handover trigger mechanism based on absolute measurement results, it can be used to trigger a time critical handover when the current serving cell becomes poor and a handover to another cell is needed; it does not meet the A3 event handover criteria.

[0045] A6 event (neighbor cell above offset from primary cell): This measurement reporting event is applicable for carrier aggregation, i.e. there is a secondary neighbor cell connected in addition to the primary serving cell.

[0046] However, in the conventional layer 3 (L3) (for example, a radio resource management layer) measurement, the base station generally configures A2 (i.e., the signal quality of the current cell is less than a threshold value) first, and then the base station may further configure A3 (i.e., the service quality of the neighboring cell is better than that of the current cell, and the difference is higher than a threshold value) according to the reporting of A2. However, when the UE reports according to the measurement event triggered by layer 1 (L1) (for example, a physical layer), the mechanism of configuring / switching the event through RRC signaling may introduce an unacceptable measurement delay (for example, the longest time may be 80 ms).

[0047] In summary, the mechanism of configuring / switching the measurement reporting event through RRC signaling may introduce a measurement and switching delay. Therefore, how to reduce the response delay of the measurement reporting event and improve the management efficiency of the measurement reporting event has become a technical problem to be solved.

[0048] The embodiments of the present disclosure provide a measurement reporting event management method, which is applied to the configuration, activation, and reporting management of multiple measurement reporting events. By pre-configuring the measurement reporting events to be managed in the first node, the first node can manage the activation / deactivation of the measurement reporting events configured by the second node without the indication of the second node, and the second node does not need to repeatedly issue the configuration of the measurement reporting events in the process of managing the measurement reporting of the first node each time. In this way, the rapid activation / deactivation of the measurement reporting event can be realized, the response delay of the measurement reporting event can be reduced, and the management efficiency of the measurement reporting event can be improved.

[0049] In the embodiments of the present disclosure, the network architecture of the mobile communication network (including but not limited to 2G, 3G, 4G, 5G, and future mobile communication networks (such as 5th generation mobile communication technology Advanced (5G-A), 6th generation mobile communication technology (6G))) can at least include a first communication node and a second communication node. It should be understood that in the present example, the first communication node can be a terminal side device (including but not limited to a terminal) in the downlink, and the second communication node can be a network (NW) side device (including but not limited to a base station). Of course, in the uplink, the first communication node can also be a network side device, and the second communication node can also be a terminal side device. In device-to-device communication, the first communication node and the second communication node can both be base stations or terminals. The first communication node and the second communication node can be referred to as the first node and the second node, respectively.

[0050] Exemplarily, as shown in FIG. 1, a communication system provided by an embodiment of the present disclosure is shown, which can include a first node 101 and a second node 102. The second node 102 can be one or more, and the number is not limited.

[0051] The second node 102 can pre-configure the first node 101 with a plurality of to-be-managed measurement reporting events, so that the first node 101 is configured with the plurality of measurement reporting events by the second node. Then, the first node 101 can implicitly manage the activation / deactivation of the plurality of measurement reporting events configured by the second node based on the activation / deactivation conditions configured by the second node for the measurement reporting events, that is, the first node 101 can manage the activation / deactivation of the plurality of measurement reporting events configured by the second node without receiving the indication of the second node 102.

[0052] Alternatively, after the second node 102 completes the pre-configuration of the plurality of measurement reporting events for the first node 101, the second node 102 can notify the first node 101 to activate / deactivate any measurement reporting event configured by the second node by issuing indication information, so that the second node 102 does not need to repeatedly configure the measurement reporting events in each process of managing the measurement reporting events of the first node 101.

[0053] It should be noted that, in the embodiments of the present disclosure, the first node can be a mobile device or a terminal device (such as a terminal), and the second node can be a network device (such as a base station).

[0054] The base station (BS) can be a base station or evolved node B (eNB or eNodeB) in LTE or long term evolution advanced (LTE-A), a base station device (gNB) in a 5G network, or a base station in a future communication system, and can include various macro base stations, micro base stations, home base stations, wireless remote units, reconfigurable intelligent surfaces (RISs), routers, relays, transmission and reception points (TRPs), wireless fidelity (WIFI) devices, and various network side devices.

[0055] The terminal can be a device with wireless transceiving function. The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiving function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and the like. Embodiments of the present disclosure are not limited to the application scenarios. The terminal can also be referred to as a user, a user equipment (UE), an access terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE apparatus, and the like. Embodiments of the present disclosure are not limited thereto.

[0056] It should be noted that FIG. 1 is only an exemplary framework diagram, the number of devices included in FIG. 1, and the name of each device are not limited, and in addition to the devices shown in FIG. 1, the communication system can also include other devices, such as core network devices.

[0057] The application scenarios of embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0058] FIG. 2 shows a flow diagram of a management method of a measurement reporting event. As shown in FIG. 2, the management method of the measurement reporting event includes:

[0059] S201, managing, based on an activation / deactivation indication mode, a measurement reporting event configured in the first node.

[0060] As an implementation manner, the first node can be preconfigured with a plurality of to-be-managed measurement reporting events. The first node can manage, based on the activation / deactivation indication mode, a measurement reporting event configured by the second node in the first node.

[0061] For example, activating the measurement reporting event, or deactivating the measurement reporting event.

[0062] It should be noted that when the event (i.e., the measurement reporting event) is activated, it means that the measurement corresponding to the event is started, and when the event is deactivated, it means that the measurement corresponding to the event is terminated.

[0063] It can be understood that, by pre-configuring the measurement reporting event to be managed in the first node, the first node can manage the activation / deactivation of the measurement reporting event configured by the second node without the indication of the second node, and the second node does not need to repeatedly issue the configuration of the measurement reporting event in each process of managing the measurement reporting of the first node. In this way, the measurement reporting event can be quickly activated / deactivated, the response delay of the measurement reporting event can be reduced, and the management efficiency of the measurement reporting event can be improved.

[0064] It should be noted that, in order to reduce the switching interruption delay and reduce the switching signaling overhead, 5G introduces a layer 1 / layer 2 (L2) triggered mobility (i.e., lower-layer triggered mobility (LTM)). The LTM is a process in which the base station triggers cell switching through a cell switching command of a medium access control control element (MAC CE) based on pre-configuration. The cell switching command indicates the LTM candidate cell configuration pre-configured by the base station through RRC signaling, and the UE switches to the corresponding target cell according to the switching command.

[0065] The overall process of LTM includes four parts: LTM preparation, advance synchronization, LTM cell switching execution, and LTM cell switching completion. Continuous LTM can reuse the pre-configured LTM candidate cell configuration, complete the cell switching by repeating the steps of advance synchronization, LTM cell switching execution, and LTM cell switching completion, and does not need to release other LTM candidate cell configurations after each LTM cell switching completion.

[0066] In addition, in the discussion of the multiple-input multiple-output (MIMO) issue of 3GPP standard 19 (release 19, R19), in order to reduce the delay and reduce the signaling overhead, the L1 measurement event reporting based on UE triggering is also proposed. In such a mechanism, the network can configure the relevant event parameters, and when the UE meets the conditions, the corresponding reporting is triggered. However, the management of multiple L1 measurement event reporting is not clear, and if multiple events are measured at the same time, unnecessary resource waste will be caused.

[0067] Therefore, in the embodiments of the present disclosure, the activation indication manner can be an explicit activation manner, or the activation indication manner can be an implicit activation manner. Similarly, the deactivation manner can be an explicit deactivation manner, or the activation indication manner can be an implicit deactivation manner.

[0068] That is, the activation / deactivation indication manner can be divided into an explicit activation / deactivation manner and an implicit activation / deactivation manner. In this way, by providing the local management and upstream indication of the measurement reporting event configured for the second node with the two activation / deactivation manners, the response order of the measurement reporting event can be reasonably arranged, and the management efficiency of the measurement reporting event can be improved.

[0069] The explicit activation / deactivation manner and the implicit activation / deactivation manner can at least meet one of the following (1)-(4) features:

[0070] (1) The explicit activation manner can be to activate the measurement reporting event in a case where the received first information sent by the second node contains activation information corresponding to the measurement reporting event;

[0071] (2) The explicit deactivation manner can be to deactivate the measurement reporting event in a case where the received first information sent by the second node contains deactivation information corresponding to the measurement reporting event;

[0072] (3) The implicit activation manner can be to activate the measurement reporting event in a case where the first node meets a preset condition corresponding to the measurement reporting event;

[0073] (4) The implicit deactivation manner can be to deactivate the measurement reporting event in a case where the first node does not meet a preset condition corresponding to the measurement reporting event.

[0074] The first information is used to manage the measurement reporting event configured in the first node, and the preset condition can be divided into a preset activation condition and a preset deactivation condition.

[0075] The explicit activation / deactivation manner and the implicit activation / deactivation manner will be described below in conjunction with example embodiments.

[0076] As an implementation manner, the first node can pre-configure a preset condition corresponding to the measurement reporting event. In the process of managing the measurement reporting event configured by the second node based on the implicit activation / deactivation manner, the first node can determine whether the preset activation / deactivation condition corresponding to the measurement reporting event configured by the second node is met according to the channel / beam quality of the first node. Then, the first node can manage the measurement reporting event configured by the second node in the first node based on the satisfaction of the preset condition corresponding to the different measurement reporting events of the first node.

[0077] If the first node determines that the first node satisfies the preset condition (i.e., the preset activation condition) corresponding to the first measurement reporting event in the plurality of measurement reporting events configured by the second node, the first node can activate the first measurement reporting event.

[0078] If the first node determines that the first node does not satisfy the preset condition (i.e., the preset activation condition) corresponding to the second measurement reporting event in the plurality of measurement reporting events configured by the second node, the first node can deactivate the second measurement reporting event.

[0079] That is, the network (i.e., the second node) indicates one or more events (i.e., measurement reporting events) to be activated in an implicit manner, which includes indicating the activation / deactivation condition (i.e., the preset condition) of the related event.

[0080] Exemplarily, when the preset condition is satisfied, the UE (i.e., the first node) automatically activates the related event (e.g., the measurement reporting event corresponding to the preset condition); when the preset condition is not satisfied, the UE deactivates the related event, i.e., does not perform measurement on the corresponding measurement object and report.

[0081] In some embodiments, the second node can configure a preset activation condition or a preset deactivation condition respectively, when the preset activation condition is satisfied, the UE activates the related event, and when the preset deactivation condition is satisfied, the UE deactivates the related event.

[0082] It should be noted that in the embodiments of the present disclosure, the preset condition can include a plurality of preset indicators and a plurality of preset thresholds, one preset indicator corresponds to one preset threshold, and the preset threshold is configured by the second node. The preset condition can be that the preset indicator is greater than / less than the corresponding preset threshold.

[0083] The present disclosure does not limit the preset indicator. For example, the preset indicator can be the channel quality (such as the channel quality indicator (CQI)) of the current channel / beam (BM). For another example, the preset indicator can be the RSRP / RSRQ / SINR of the current channel / beam. For another example, the preset indicator can be the block error rate (BLER). For another example, the preset indicator can be the received signal strength indicator (RSSI).

[0084] That is, the activation / deactivation condition (i.e., the preset condition) of the event (i.e., the measurement reporting event) can be that the channel quality of the current beam is less than / greater than a certain threshold, and the threshold is configured by the network (i.e., the second node).

[0085] As an implementation manner, the first node can receive first information from the second node, and determine whether the first information contains activation / deactivation information of a plurality of measurement reporting events configured by the second node. Then, the first node can manage the measurement reporting events configured by the second node in the first node based on the activation / deactivation information contained in the first information.

[0086] If the first information contains activation information corresponding to a third measurement reporting event in the plurality of measurement reporting events configured by the second node, the first node can activate the third measurement reporting event.

[0087] If the first information contains deactivation information corresponding to a fourth measurement reporting event in the plurality of measurement reporting events configured by the second node, the first node can deactivate the fourth measurement reporting event.

[0088] It should be noted that in the embodiments of the present disclosure, the first information can be any one of the following: information of a physical layer, information of a data link layer, and information of a network layer.

[0089] That is, the first information can be L1 / L2 / L3 information, and the second node can issue the activation / deactivation indication to the first node through L1 / L2 / L3. Moreover, compared with L3, the issue of the activation / deactivation indication through L1 and L2 can have lower latency.

[0090] In some embodiments, the information of the physical layer can be downlink control information (DCI), the information of the data link layer can be MAC CE (or lower layer control element), and the information of the network layer can be RRC signaling.

[0091] That is, the network (i.e., the second node) can indicate one or more events (i.e., measurement reporting events) to be activated in an explicit manner, which includes indicating through RRC signaling, MAC CE, or DCI.

[0092] It should be noted that the MAC CE can include one or more bits for indicating the activation / deactivation of the measurement reporting events, and the DCI can also include one or more bits for indicating the activation / deactivation of the measurement reporting events.

[0093] Moreover, in the case where the first information is DCI, the second information (or other RRC layer configuration information) sent by the second node and received by the first node contains information indicating whether the DCI contains activation information / deactivation information.

[0094] That is, in the DCI manner, an activation / deactivation bit can be designed for the corresponding event (i.e., the measurement reporting event), and whether the event activation / deactivation bit is included in the DCI can be indicated in the RRC signaling (e.g., the second information).

[0095] For the MAC CE manner, multiple bits can be included in the MAC CE, each bit corresponding to an event (i.e., a measurement reporting event) configured by the network (i.e., the second node), for example, the network configures 2 events, the first bit can be used for the first event, and the second bit can be used to indicate the second event.

[0096] For the RRC signaling manner, the activation or deactivation corresponding to each event can be indicated by the RRC signaling.

[0097] It should be noted that the above three manners can also be mixed, for example, the initial activation / deactivation state is indicated by the RRC signaling, and then the activation / deactivation state update is indicated by the DCI / MAC CE.

[0098] In some embodiments, before the first node manages the measurement reporting events configured in the first node based on the activation / deactivation indication manner (i.e., S201), the first node can receive the second information sent by the second node. The second information is used to configure one or more measurement reporting events for the first node.

[0099] In some embodiments, the second information can include a preset activation / deactivation condition corresponding to each measurement reporting event.

[0100] It can be understood that the second node first configures multiple events (i.e., measurement reporting events) corresponding to the candidate cells or beams, and then explicitly or implicitly indicates one or more events to be activated. In this way, the second node pre-configures all measurement reporting events in the first node, so that the second node does not need to repeatedly issue the configuration of the measurement reporting event in the process of managing the measurement reporting of the first node, so as to improve the response speed of the first node to the measurement reporting event and improve the management efficiency of the measurement reporting event.

[0101] In some embodiments, the measurement reporting event can be an event based on L1 measurement, or the measurement reporting event can be an event based on L3 measurement. Moreover, the event can be used for different purposes, such as beam management and inter-cell mobility management.

[0102] As an implementation manner, the measurement reporting event can be any one of the following (1)-(8):

[0103] (1) a measurement reporting event in beam management;

[0104] (2) Measurement reporting events in inter-cell mobility management;

[0105] (3) Measurement reporting events based on physical layer measurements;

[0106] (4) Measurement reporting events based on radio resource management layer measurements;

[0107] (5) Measurement reporting events based on physical layer measurements in beam management;

[0108] (6) Measurement reporting events based on radio resource management layer measurements in beam management;

[0109] (7) Measurement reporting events based on physical layer measurements in inter-cell mobility management;

[0110] (8) Measurement reporting events based on radio resource management layer measurements in inter-cell mobility management.

[0111] Exemplarily, the events in beam management can include: event BM1, event BM2, event BM3, event BM4, and event BM5.

[0112] Event BM1: Channel quality of a current beam is lower than a threshold;

[0113] Event BM2: Channel quality of a new beam is better than channel quality of a current beam, and a difference between channel quality of the new beam and channel quality of the current beam is greater than a threshold;

[0114] Event BM3: Channel quality of a new beam is better than <Mth best / worst beam among reference signals corresponding to activated transmission configuration indication (TCI) states>, and a difference between channel quality of the new beam and channel quality of the Mth beam is greater than a threshold;

[0115] Event BM4: Channel quality of a current beam is higher than a threshold;

[0116] Event BM5: Channel quality of a new beam is higher than a threshold.

[0117] The events in inter-cell mobility management can include: event LTM1, event LTM2, event LTM3, event LTM4, event LTM5, event LTM6, event LTM7, and event LTM8.

[0118] Event LTM1: Channel quality of a beam of a current serving cell is lower than a threshold;

[0119] Event LTM2: Channel quality of a beam of a current serving cell is higher than a threshold;

[0120] Event LTM3: Channel quality of a beam of a candidate cell is better than channel quality of a beam of a current serving cell, and a difference between the channel quality of the beam of the candidate cell and the channel quality of the beam of the current serving cell is greater than a threshold value;

[0121] Event LTM4: Channel quality of a beam of a current serving cell is lower than a threshold value, and channel quality of a beam of a candidate cell is better than the threshold value;

[0122] Event LTM5: Channel quality of a beam of a neighbor cell is higher than a threshold value;

[0123] Event LTM6: Channel quality of a beam of a neighbor cell is higher than a bias of a beam of a serving cell;

[0124] Event LTM7: Channel quality of a beam of a neighbor cell of a different system is higher than a threshold value of a beam of a serving cell;

[0125] Event LTM8: Channel quality of a beam of a serving cell is lower than a threshold value 1, and channel quality of a beam of a neighbor cell of a different system is higher than a threshold value 2.

[0126] It should be noted that, in the embodiments of the present disclosure, the beam in the beam management is a beam of a current serving cell accessed by the first node, or the beam in the beam management is a beam of another serving cell or a non-serving cell.

[0127] That is, the beam can be a serving beam of the current serving cell, or can be another beam of the current serving cell, or can be a beam of a non-serving cell (for example, a candidate cell).

[0128] In the embodiments of the present disclosure, the configuration information of the measurement reporting event can include at least one of the following: a type of a reference signal, a measurement index of the reference signal, a threshold value of the measurement index, and a reporting parameter of the measurement reporting event.

[0129] The reporting parameter of the measurement reporting event can include at least one of the following: a monitoring duration, a threshold value of a number of samples in the monitoring duration, a reporting period, and a threshold value of a number of continuous reports.

[0130] That is, the network (i.e., the second node) can configure: one or more events (i.e., measurement reporting events), which can be used for beam management or mobility management; a reference signal type corresponding to each event, such as a channel state information-reference signal (CSI-RS) or a synchronization signal block (SSB); a measurement quantity (i.e., a measurement index) of the reference signal, such as RSRP, RSRQ, or SINR; a threshold value (i.e., a threshold value of the measurement index) corresponding to each event; and related configurations of event triggering (i.e., reporting parameters of the measurement reporting event), including, for example, a length of a statistical time window (a monitoring duration), a maximum number of times of triggering within the time window (i.e., a threshold value of the number of samples within the monitoring duration), an event reporting interval (i.e., a reporting period), and the like.

[0131] Exemplarily, taking beam management as an example, the events in beam management can include event BM1, event BM2, and event BM3. The network (i.e., the second node) configures configuration 1 of event BM1, configuration 2 of event BM2, and configuration 3 of event BM3 through RRC signaling (such as a reconfiguration message) as follows.

[0132] (1) Configuration 1 of event BM1:

[0133] Reference signal (RS) type: i.e., a reference signal type, which can be SSB or CSI-RS, or the like;

[0134] Report threshold A: i.e., a threshold value of event BM1;

[0135] Window length: i.e., a monitoring duration, which is a sliding window duration. Within an event window of this length, the number of samples of event BM1 is counted;

[0136] Instance max count: i.e., a maximum value of samples. When the number of samples of event BM1 within the window reaches the set maximum number, corresponding event reporting can be performed;

[0137] Report interval: i.e., a frequency or period of event reporting. This duration can be one or more periods of the corresponding reference signal.

[0138] Report amount: the total number of consecutive reports of this event. When the total number reaches this value, stop reporting. This value is cleared to 0 after beam switching;

[0139] Report on leave: indicates to the network when the channel quality of the beam measured by the UE no longer meets the condition.

[0140] (2) Configuration 2 of event BM2:

[0141] Reference signal configuration of new beam: the configuration of the reference signal corresponding to the new beam includes the reference signal type, such as SSB or CSI-RS, and the corresponding configuration, etc.

[0142] Report threshold B: the threshold of event BM2.

[0143] Window length: the monitoring duration, which is the sliding window duration. Within an event window of this length, the number of samples of event BM2 is counted.

[0144] Maximum sample count: the maximum number of samples. When the number of samples of event BM2 within the window reaches the maximum number set, the corresponding event report can be made.

[0145] Report interval: the frequency or period of event reporting. This duration can be one or more periods of the corresponding reference signal.

[0146] Report amount: the total number of consecutive reports of this event. When the total number reaches this value, stop reporting. This value is cleared to 0 after beam switching;

[0147] Report on leave: indicates to the network when the channel quality of the beam measured by the UE no longer meets the condition.

[0148] (3) Configuration 3 of event BM3:

[0149] Reference signal configuration of new beam: the configuration of the reference signal corresponding to the new beam includes the reference signal type, such as SSB or CSI-RS, and the corresponding configuration, etc.

[0150] Report threshold C: the threshold of event BM3.

[0151] Window length: the monitoring duration, which is the sliding window duration. Within an event window of this length, the number of samples of event BM3 is counted.

[0152] Maximum sample count: the maximum number of samples. When the number of samples of event BM3 within the window reaches the maximum number set, the corresponding event report can be made.

[0153] Reporting interval: i.e. the frequency or period of reporting of the event, the duration can be one or more periods of the corresponding reference signal.

[0154] Reporting amount: i.e. the total number of consecutive reporting of the event, when the total number reaches the value, stop reporting. The value is cleared 0 after beam switching;

[0155] Reporting stop: i.e. indicating the network when the channel quality of the beam measured by the UE no longer meets the condition.

[0156] In some embodiments, the configuration information of the measurement reporting event can also include the cell identification accessed by the UE.

[0157] That is, in the process of reporting measurement data to the upstream device (such as a base station) based on the measurement reporting event, the UE can also report the identification of the cell currently accessed by the UE, so that the upstream device can subsequently manage the UE based on the measurement data.

[0158] In some embodiments, the configuration granularity of the measurement reporting event includes at least one of the following: user equipment, frequency point, cell, resource set (a set of resources for transmitting a specific type of control information or data, such as control resource set (CORESET)), type of reference signal.

[0159] That is, the network (i.e. the second node) can configure events (i.e. measurement reporting events) of different granularities, and this granularity can be based on UE, or based on each frequency point, or based on each cell, or based on each resource set, or based on each type of reference signal. The granularity based on UE, i.e. the configuration is for all cells in a UE, i.e. applicable to any cell, any frequency point, any resource set, and any reference signal type of the UE. The granularity based on frequency point, i.e. the configuration is for a certain frequency point. The granularity based on cell, i.e. the configuration is for the corresponding cell. The granularity based on resource set, i.e. the configuration is for the corresponding resource set.

[0160] Exemplarily, taking the measurement reporting event configured by the network (second node) of different cell granularities as an example, other granularities can refer to the same logic. That is, the same granularity (such as cell, frequency point, resource set) can be indicated for its event (i.e. measurement reporting event), or the same event can be indicated for its associated granularity (such as cell, frequency point, resource set). For example, in the granularity configuration at the cell level, each cell can be defined as an event, or each (per) event can indicate the related cell.

[0161] For example, in the reconfiguration message, the configuration of event BM1 for cell 1 (as configuration 1 above), the configuration of event BM2 for cell 1 (as configuration 2 above), and the configuration of event BM3 for cell 1 (as configuration 3 above), the configuration of event BM1 for cell 2 (as configuration 1 above), the configuration of event BM2 for cell 2 (as configuration 2 above), and the configuration of event BM3 for cell 2 (as configuration 3 above).

[0162] That is, the configuration of event BM1 for cell 1:

[0163] {the configuration of event BM1: configuration 1;

[0164] the configuration of event BM2: configuration 2;

[0165] the configuration of event BM3: configuration 3}.

[0166] the configuration of event BM1 for cell 2:

[0167] {the configuration of event BM1: configuration 1;

[0168] the configuration of event BM2: configuration 2;

[0169] the configuration of event BM3: configuration 3}.

[0170] For another example, in the reconfiguration message, the configuration of event BM1 includes: the parameters of cell 1 (as configuration 1 above), the parameters of cell 2 (as configuration 2 above), and the parameters of cell 3 (as configuration 3 above), the configuration of event BM2 includes: the parameters of cell 1 (as configuration 1 above) and the parameters of cell 2 (as configuration 2 above), and the configuration of event BM3 includes: the parameters of cell 1 (as configuration 1 above) and the parameters of cell 2 (as configuration 2 above).

[0171] That is, the configuration of event BM1:

[0172] {the parameters of cell 1: configuration 1;

[0173] the parameters of cell 2: configuration 2;

[0174] the parameters of cell 3: configuration 3}.

[0175] the configuration of event BM2:

[0176] {the parameters of cell 1: configuration 1;

[0177] the parameters of cell 2: configuration 2;}.

[0178] the configuration of event BM3:

[0179] {the parameters of cell 1: configuration 1;

[0180] the parameters of cell 2: configuration 2;}.

[0181] It should be noted that the above various granularities can be combined, for example, based on the configuration of a certain resource set under a cell.

[0182] As an implementation manner, one measurement reporting event configuration can be associated with multiple cells, or one cell can be associated with multiple measurement reporting event configurations.

[0183] Exemplarily, cell 1 can be configured in multiple measurement reporting events (such as event 1, event 2, event 3), and the configuration of event 1 can include multiple cells (such as cell A, cell B, and cell C).

[0184] Similarly, one measurement reporting event configuration can be associated with multiple cells, or one cell can be associated with multiple measurement reporting event configurations.

[0185] One measurement reporting event configuration can be associated with multiple UEs, or one UE can be associated with multiple measurement reporting event configurations.

[0186] One measurement reporting event configuration can be associated with multiple frequency points, or one frequency point can be associated with multiple measurement reporting event configurations.

[0187] One measurement reporting event configuration can be associated with multiple resource sets, or one resource set can be associated with multiple measurement reporting event configurations.

[0188] One measurement reporting event configuration can be associated with multiple reference signal types, or one reference signal type can be associated with multiple measurement reporting event configurations.

[0189] In some embodiments, in combination with the above-mentioned activation / deactivation indication manner, the above-mentioned activation / deactivation indication manner can also synchronize the configuration granularity corresponding to the measurement reporting event.

[0190] That is, different granularities of activation / deactivation indication (i.e. the above-mentioned activation / deactivation indication manner) can be defined, and this granularity can be based on UE, or based on each frequency point, or based on each cell, or based on each reference signal type, or based on each resource set. And this granularity can be indicated in the preset condition of activation / deactivation (i.e. implicit activation / deactivation), or can be indicated in the underlying control resource such as MAC CE (i.e. explicit activation / deactivation).

[0191] Exemplarily, various granularities are further represented as shown in (1)-(5) as follows:

[0192] (1) UE-based granularity, i.e., the indication is for all cells in one UE, i.e., applicable to any cell, any frequency point, any resource set, and any reference signal type of the UE;

[0193] (2) Frequency point-based granularity, i.e., the indication is for a certain frequency point, i.e., the activation / deactivation indication is only valid for the frequency point or events associated with the frequency point;

[0194] (3) Cell-based granularity, i.e., the indication is for a corresponding cell, i.e., the activation / deactivation indication is only valid for the cell or events associated with the cell;

[0195] (4) Resource set-based granularity, i.e., the indication is for a corresponding resource set configuration, i.e., the activation / deactivation indication is only valid for the resource set or events associated with the resource set;

[0196] (5) Reference signal type-based granularity, i.e., the indication is for a corresponding reference signal type, i.e., the activation / deactivation indication is only valid for the reference signal type or events associated with the reference signal type.

[0197] It should be noted that various granularities can be indicated in the activation / deactivation condition (i.e., preset condition), i.e., when the activation / deactivation condition is configured, the granularity to which the condition applies is indicated. Alternatively, various granularities can be indicated in the underlying control resource (i.e., first information) such as MAC CE, i.e., when the activation / deactivation is indicated in the underlying control resource such as MAC CE, the applicable granularity is also indicated.

[0198] As an implementation manner, taking the indication in the first information with cell granularity as an example, the first information can be indication information of the cell in which the first node is located (e.g., the cell in which the MAC CE is received), or the first information can be cross-cell indication information.

[0199] Similarly, the first information can also be applicable to other granularities (i.e., UE granularity, frequency point granularity, resource set granularity, and reference signal type granularity).

[0200] The embodiments of the present disclosure also provide a measurement reporting event management method, which is executed by a second node, as shown in FIG. 3, and can include the following steps:

[0201] S301, sending first information to a first node.

[0202] As an implementation manner, the second node can send the first information to the first node in response to a user operation / preset management strategy.

[0203] It should be noted that the introduction of the first information can refer to the description of the first information in the above embodiments, which will not be repeated here.

[0204] In some embodiments, before the second node sends the first information to the first node (i.e., before S301), the second node can also send the second information to the first node.

[0205] It should be noted that the introduction of the second information can refer to the description of the second information in the above embodiments, which will not be repeated here.

[0206] The management method of the measurement reporting event provided by the embodiments of the present disclosure will be introduced below in combination with example embodiments. As shown in FIG. 4, the management method of the measurement reporting event in the embodiments of the present disclosure can include:

[0207] S401, the second node sends the second information to the first node.

[0208] S402, the first node receives the second information from the second node.

[0209] S403, the first node locally configures the measurement reporting event in the second information.

[0210] In some embodiments, after the first node completes the pre-configuration of the measurement reporting event, the measurement reporting event configured by the second node can be managed by an explicit activation / deactivation mode (i.e., S404-S408) or an implicit activation / deactivation mode (i.e., S409-S411).

[0211] S404, the second node sends the first information to the first node.

[0212] S405, the first node receives the first information from the second node.

[0213] S406, the first node determines whether the first information contains the activation / deactivation information corresponding to the measurement reporting event.

[0214] The first node can determine whether the first information contains the activation information corresponding to the unactivated measurement reporting event or the deactivation information corresponding to the activated measurement reporting event.

[0215] In some embodiments, if the first node determines that the first information contains the activation information corresponding to the unactivated measurement reporting event, the first node can perform S407.

[0216] S407, the first node activates the measurement reporting event.

[0217] In other embodiments, if the first node determines that the first information contains the deactivation information corresponding to the measurement reporting event, the first node can perform S408.

[0218] S408, the first node deactivates the measurement reporting event.

[0219] S409, the first node determines whether the first node satisfies a preset activation / deactivation condition corresponding to the measurement reporting event.

[0220] In some embodiments, if the first node determines that the first node satisfies the preset activation condition corresponding to the measurement reporting event, the first node can perform S410.

[0221] S410, the first node activates the measurement reporting event.

[0222] In other embodiments, if the first node determines that the first node does not satisfy the preset activation condition corresponding to the measurement reporting event or satisfies the preset deactivation condition corresponding to the measurement reporting event, the first node can perform S411.

[0223] S411, the first node deactivates the measurement reporting event.

[0224] The implicit activation / deactivation manner and the explicit activation / deactivation manner are described below in conjunction with examples.

[0225] I. Implicit activation / deactivation manner.

[0226] Exemplarily, as shown in FIG. 5, the gNB (i.e., the second node) can send a reconfiguration message (containing event configuration) to the UE, and then the UE can feed back a reconfiguration complete message to the gNB. After that, the UE can determine whether the event activation condition is satisfied, and in the case that the event activation condition is satisfied, trigger the event related measurement (i.e., trigger the measurement reporting event). Then, the UE can determine whether the event reporting condition is satisfied, and in the case that the event reporting condition is satisfied, send an event report to the gNB.

[0227] That is, the network (i.e. the second node) indicates one or more events (i.e. measurement reporting events) to be activated in an implicit manner, which includes indicating the activation condition of the relevant event, when the condition is met, the UE automatically activates the relevant event, i.e. starts to do the measurement / reporting of the corresponding measurement object (when the reporting condition is met), when the condition is not met, the UE deactivates the relevant event, i.e. does not do the measurement / reporting of the corresponding measurement object.

[0228] In some embodiments, the measurement reporting event based on the implicit activation / deactivation manner can further include a preset condition corresponding to the measurement reporting event itself.

[0229] Exemplarily, taking event BM1 and event BM2 as examples, in the case of implicit activation / deactivation manner, the network (i.e. the second node) can configure the activation condition (i.e. preset condition D) corresponding to event BM2 at the same time. For example, when the channel quality of the current beam is less than a certain threshold (denoted as threshold C), the relevant measurement of event BM2 is triggered. Then the network can configure event BM2 as follows:

[0230] The configuration of event BM1 is the same as the above configuration 1;

[0231] The configuration of event BM2 includes the following (1)-(8):

[0232] (1) Reference signal configuration (config) of new beam: that is, the configuration of the reference signal corresponding to the new beam includes the reference signal type, which can be SSB or CSI-RS, etc. and the corresponding configuration, etc.

[0233] (2) Reporting threshold B: that is, the threshold of event BM2;

[0234] (3) Window length: that is, the monitoring duration, with this duration as the sliding window duration, within such a length of event window, the samples of event BM2 are counted;

[0235] (4) Maximum sample count: that is, the maximum value of the sample, when the sample of event BM2 within the window reaches the maximum number set, the corresponding event reporting can be done;

[0236] (5) Reporting interval: that is, the frequency or period of event reporting, this duration can be one or more periods of the corresponding reference signal.

[0237] (6) Reporting amount: that is, the total number of consecutive reporting of the event, when the total number reaches the value, the reporting is stopped. The value is cleared to 0 after beam switching;

[0238] (7) Reporting stop: that is, instructing the network when the channel quality of the beam measured by the UE no longer meets the condition;

[0239] (8) Event activate threshold: the preset condition D mentioned above, for example, the threshold is used to indicate when the UE triggers the measurement corresponding to the event BM2, for example, the threshold can be set as a reference of the signal quality of the current beam, that is, when the signal quality of the current beam is lower than the threshold (that is, the signal quality is worse than a value), the measurement corresponding to the event BM2 is activated, for example, the measurement of the new beam configured in the event BM2. When the signal quality of the current beam is higher than the threshold, the measurement corresponding to the event BM2 can be closed. For the closing condition, the network can also configure another threshold, for example, D1. Here, the measurement (that is, the index) of D and D1 can be RSRP / RSRQ / SINR, etc. Here, an event deactivation threshold can also be configured, which is used to indicate when the UE triggers the measurement corresponding to the event BM2, for example, the threshold can be set as a reference of the signal quality of the current beam, that is, when the signal quality of the current beam is better than the threshold (that is, the signal quality is better than a value), the measurement corresponding to the event BM2 is deactivated. Here, the measurement can also be RSRP / RSRQ / SINR, etc.

[0240] (1)-(7) are the same as configuration 2.

[0241] That is, when the UE receives such a configuration, it will only measure the beam corresponding to the event BM1, that is, the current beam at the beginning. When the measured value is less than the threshold D, the UE will start the beam measurement corresponding to the event BM2. When the measured value of the current beam is greater than the threshold D (or D1 if configured), the UE will stop the measurement corresponding to the event BM2 and the reporting. The event BM3 is similar, and the network can also configure the threshold for starting the measurement corresponding to the event BM3. Different events can be configured with the same set of thresholds or different thresholds.

[0242] In some embodiments, for the implicitly activated / deactivated measurement reporting events of different granularities configured by the network (that is, the second node), the granularity of activation / deactivation can be indicated as described in the above embodiments. Here, for the implicit method, the activation / deactivation conditions are configured, so that when the activation / deactivation conditions are configured, the granularity applicable to these conditions is indicated. For example, the granularity mentioned in the above embodiments.

[0243] Exemplarily, taking the granularity of a cell as an example, when the activation / deactivation conditions are set, the activation / deactivation conditions can be set for each cell, or the related cell can be indicated for the activation / deactivation conditions.

[0244] For example, for each cell, the conditions for activation / deactivation are set in the reconfiguration message:

[0245] {Cell 1:

[0246] {Configuration of event BM1:

[0247] Configuration 1;

[0248] Configuration of event BM2:

[0249] Configuration 2

[0250] Event triggering threshold D;

[0251] Configuration of event BM3:

[0252] Configuration 3};

[0253] Cell 1:

[0254] {Configuration of event BM1:

[0255] Configuration 1;

[0256] Configuration of event BM2:

[0257] Configuration 2

[0258] Event triggering threshold D;

[0259] Configuration of event BM3:

[0260] Configuration 3}.

[0261] And if another, that is, can be additional indication of the conditions for activation / deactivation of the cell, or the applicable event, or its applicable reference signal type, resource set, frequency point, etc.

[0262] For example, in the reconfiguration message:

[0263] {Cell 1:

[0264] {Configuration of event BM1: Configuration 1;

[0265] Configuration of event BM2: Configuration 2;

[0266] Configuration of event BM3: Configuration 3};

[0267] Cell 2:

[0268] {Configuration of event BM1: Configuration 1;

[0269] Configuration of event BM2: Configuration 2;

[0270] Configuration of event BM3: Configuration 3;

[0271] Event triggering threshold D;

[0272] Applicable cell IDs: cell 1, cell 2, …, cell n;

[0273] Applicable events: event 1, event 2, …, event m;

[0274] Adaptive resource set: resource set 1, resource set 2, …, resource set x;

[0275] Applicable frequency points: frequency point 1, frequency point 2, …, frequency point y;

[0276] Type of applicable reference signal: type 1, type 2, …, type z.

[0277] Another implicit deactivation method is based on a clock, i.e., when the measurement reporting event activation time exceeds a time threshold, the measurement reporting event is deactivated. The clock can be configured by the network or specified by the protocol. The time threshold can be defined separately for a single measurement reporting event or for multiple measurement reporting events.

[0278] II. Explicit activation / deactivation method

[0279] For example, as shown in FIG. 6, the gNB (i.e., the second node) can send a reconfiguration message (containing event configuration) to the UE, and then the UE can feed back a reconfiguration complete message to the gNB. After that, the gNB can send a MAC CE or DCI (containing event activation / deactivation indication) to the UE. Then, the UE can determine whether the event activation indication is contained in the MAC CE or DCI from the gNB, and in the case of determining that the event activation indication is contained, trigger event related measurement (i.e., trigger the measurement reporting event), and in the case of satisfying the event report condition, send an event report to the gNB.

[0280] That is, the network (i.e. the second node) indicates the one or more events (i.e. measurement reporting events) to be activated by explicit way, which includes RRC signaling, MAC CE or DCI, etc.

[0281] If explicit way is used, the network can indicate the activation status of each event by RRC signaling, MAC CE or DCI, etc., i.e. set the initial activation status when doing event configuration, and then indicate the change of the activation status by MAC CE / DCI. For example, in the initial event configuration, event 1 is activated and event 2 is deactivated, then the network can indicate event 2 to be activated by MAC CE or DCI. When an event is activated, the UE starts the corresponding measurement and reporting (when the reporting condition is met), and when the event is deactivated, the UE stops the corresponding measurement and reporting.

[0282] In some embodiments, taking the explicit activation / deactivation way based on MAC CE as an example, for the MAC CE scheme, multiple bits can be included in the MAC CE, each bit corresponding to an event configured by the network (i.e. the second node), for example, the network configures 2 events, the first bit can be used for the first event, and the second bit can be used to indicate the second event.

[0283] Exemplarily, as shown in Table 1, the bit distribution of the measurement reporting event and the corresponding activation / deactivation indication in the MAC CE is shown.

[0284] Table 1 Bit distribution of MAC CE

[0285] Wherein, event bits set to 1 means activating the corresponding event;

[0286] event bits set to 0 means deactivating the corresponding event.

[0287] When the event is activated, it means starting the measurement corresponding to the event, and deactivation means terminating the measurement corresponding to the event.

[0288] As described above, the event can be used for different purposes, such as beam management and mobility management. The MAC can set different MAC CEs for different purposes, or use the same MAC CE.

[0289] For different MAC CEs, such as beam management MAC CE, mobility management MAC CE, the mobility management MAC CE can be further divided into MAC CE of LTM, and MAC CE for traditional L3 measurement. Here, taking the beam management MAC CE as an example, as shown in Table 2 and Table 3, which respectively show the MAC CE of the beam event and the MAC CE of the LTM event.

[0290] Table 2 Bit distribution of MAC CE of beam event

[0291] Revent bits

[0292] Table 3 Bit distribution of MAC CE of LTM event

[0293] Revent bits

[0294] It should be noted that in the event bit, the correspondence between each bit and the event configured by the RRC signaling in the configuration 1, the configuration 2 and the configuration 3 above can be defined, for example, the first bit corresponds to the event BM1, the second bit corresponds to the event BM2, and so on. The same bit is set to 1: which represents activating the corresponding event, and the bit is set to 0: which represents deactivating the corresponding event, and vice versa. If the MAC CE is defined for the LTM event, the same logic is adopted.

[0295] Here, the measurement reporting event identifier can also be displayed in the MAC CE. In the MAC CE, the bit of the measurement reporting event identifier (i.e. report bits) is adjacent to the bit occupied by the activation / deactivation indication corresponding to the event (i.e. event bit).

[0296] If some integrated MAC CEs are used, such as the event management of the integration of beam management and mobility management, the correspondence between each bit and the related event configured by the RRC signaling can be defined, as shown in Table 4, which shows the MAC CE of the integration of the beam event and the LTM event.

[0297] Table 4 Bit distribution of MAC CE of the integration of beam event and LTM event

[0298] For example, if there are 3 beam management and 4 mobility management events, 7 bits can be used, 1-3 bits indicate the activation / deactivation of the beam management event, and 4-7 bits indicate the activation / deactivation of the corresponding mobility management event. Some indications can also be added in the MAC CE to indicate whether the corresponding bits of the beam management or mobility management event are included, or to indicate which type of event activation / deactivation indication is included in the MAC CE.

[0299] As an implementation manner, taking the explicit activation / deactivation based on different granularity of MAC CE as an example, the network (i.e., the second node) can further indicate the granularity to which the activation / deactivation is applicable, for example, the cell granularity.
