For the specific description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd generation partnership project (3GPP). The access network device can be a macro base station (such as Figure 1 110a), or a micro base station or an indoor station (such as Figure 1110b), may also be a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the access network device. For ease of description, the following description takes a base station as an example of an access network device.

[0082] The roles of the base station and the UE may be relative, for example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile base station. For the UE 120j that accesses the wireless access network 100 through 120i, UE 120i is a base station; but for the base station 110a, 120i is a UE, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and UEs can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1120a-120j in the figure can be referred to as a communication device with UE function.

The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0083] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem including the base station functions. The control subsystem including the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the UE may also be performed by a module (such as a chip or a modem) in the UE, or by a device including the UE functions.

[0084] In this application, the base station sends a downlink signal or downlink information to the UE, and the downlink information is carried on the downlink channel; the UE sends an uplink signal or uplink information to the base station, and the uplink information is carried on the uplink channel. In order to communicate with the base station, the UE needs to establish a wireless connection with the cell controlled by the base station. The cell with which the UE has established a wireless connection is called the service cell of the UE. When the UE communicates with the service cell, it will also be interfered by signals from neighboring cells.

[0085] In this application, at least one of the core network equipment, base station, UE or operation administration and maintenance (OAM) etc. may be deployed with an AI model, and the AI ​​model is used to implement the corresponding functions. The deployment method can be found in Figure 2As shown. Among them, the AI ​​model characterizes the mapping relationship between the input and output of the AI ​​model. The AI ​​model can be a neural network, a linear regression AI model, a decision tree AI model, a support vector machine (SVM), a Bayesian network, a Q learning AI model or other machine learning AI models. The AI ​​model may include an algorithm or parameter for implementing AI. In the present application, the AI ​​model can be used for load prediction, UE trajectory prediction, channel state information prediction, optimal beam prediction, positioning prediction, measurement configuration information prediction, etc. In addition, the AI ​​model can also perform strategy reasoning from the perspectives of network energy saving and mobility optimization based on the prediction results of the network performance of the base station by the trained AI model, so as to obtain reasonable and efficient energy saving strategies, mobility optimization strategies, etc. In the present application, the AI ​​models deployed in different nodes may be the same or different. The difference in AI models includes at least one of the following differences: different structural parameters of the AI ​​model, for example, different number of layers and / or weights of the AI ​​model; different input parameters of the AI ​​model; or different output parameters of the AI ​​model. Among them, the different input parameters of the AI ​​model and / or the output parameters of the AI ​​model can be described as different functions of the AI ​​model. In addition, AI models can also be distinguished by their applicable scenarios or the different data sets used for training.

[0086] like Figure 3 As shown, it is a schematic diagram of an application architecture of an AI model. The data source is used to store training data and inference data. The AI ​​model training host obtains an AI model by analyzing or training the training data provided by the data source, and deploys the AI ​​model in the AI ​​model inference host. Optionally, the AI ​​model training node can also update the AI ​​model deployed on the AI ​​model inference node. The AI ​​model inference node can also feedback relevant information of the deployed AI model to the AI ​​model training node, so that the AI ​​model training node can optimize or update the deployed AI model.

[0087] Among them, learning and obtaining the AI ​​model through the AI ​​model training node is equivalent to the AI ​​model training node using the training data to learn the mapping relationship between the input and output of the AI ​​model. The AI ​​model reasoning node uses the AI ​​model to perform reasoning based on the reasoning data provided by the data source to obtain the reasoning result. The method can also be described as: the AI ​​model reasoning node inputs the reasoning data into the AI ​​model, and obtains the output through the AI ​​model, and the output is the reasoning result. The reasoning result may indicate: the configuration parameters used (executed) by the execution object, and / or the operation performed by the execution object. The reasoning result can be uniformly planned by the execution (actor) entity and sent to one or more execution objects (for example, network entities) for execution. Optionally, the execution entity or execution object can feed back the parameters or measurements it collects to the data source. This process can be called performance feedback, and the parameters fed back can be used as training data or reasoning data. Optionally, the execution entity or execution object can also determine feedback information related to the AI ​​model performance based on the inference results output by the AI ​​model inference node, and feed the feedback information back to the AI ​​model inference node. The AI ​​model inference node can feed back the performance information of the AI ​​model to the AI ​​model training node based on the feedback information, so that the AI ​​model training node can optimize or update the deployed AI model, etc. This process can be called AI model feedback.

[0088] Cell reselection refers to the process in which the UE, in the radio resource control (RRC) idle state, monitors the signal quality of neighboring cells and the current serving cell (or the currently resident cell) to select a cell with better signal quality than the current serving cell to reside in. Furthermore, when the signal quality and level of the neighboring cell meet the S criterion and certain reselection decision criteria, the UE will reside in the neighboring cell (i.e., complete the cell reselection process). After the UE successfully resides, it will continue to measure the cell and determine again whether to start the decision condition for neighboring cell measurement. The UE can further determine whether to perform cell reselection based on the signal quality of the neighboring cell.

[0089] Normally, a base station in a cell broadcasts the measurement configuration information corresponding to the cell, and accordingly, the UE in the cell can receive the measurement configuration information, and then measure the reference signal and determine the cell reselection according to the measurement configuration information. The measurement configuration information may specify parameters such as the measurement start threshold, measurement interval, measurement cycle, neighbor cell identifier, neighbor cell priority, and reselection threshold.

[0090] The measurement configuration information broadcast by the base station is at the cell granularity, that is, within the cell range, all UEs use the same measurement configuration information for cell reselection. Multiple UEs located in the cell may have different states, for example, different UEs have different moving speeds and / or moving directions, or different UEs may be located in different areas of the cell. The cell-level measurement configuration information cannot adapt to the state of each UE. For example, for UEs with faster moving speeds, a shorter measurement interval can be configured; for UEs located in areas with poor signal quality, a lower measurement start threshold can be configured so that the UE can quickly reselect to a cell with better signal quality. For another example, for UEs with slower moving speeds (or stationary), a longer measurement interval can be configured to achieve UE energy saving.

[0091] To this end, the present application provides a communication method for a base station to generate measurement configuration information adapted to the state of a UE. The steps performed by the UE in the communication method may be implemented by a module in the UE, and the steps performed by the base station may be implemented by a module in the base station. For ease of description, the following takes the execution of the UE and the base station as an example.

[0092] like Figure 4 A flow chart of the first communication method provided for this application:

[0093] Step 401: A first UE sends auxiliary information to a base station, and correspondingly, the base station receives the auxiliary information from the first UE.

[0094] 1. Auxiliary information includes one or more of the following parameter types (1) to (7):

[0095] (1) RRM measurement results when the UE performs cell selection.

[0096] (2) RRM measurement results when the UE performs cell reselection.

[0097] Among them, cell selection refers to which cell the UE first selects to reside in when it is turned on; cell reselection refers to the UE further reselecting to other cells when it resides in a certain cell.

[0098] The RRM measurement result may include, but is not limited to, one or more of the following: the measurement amount of the resident cell entered / left by the UE (or referred to as the measurement result of the measurement amount, similar expressions are given below), the UE type, the state of the UE corresponding to the measurement amount, the time corresponding to the measurement amount, and the cell identifier.

[0099] Optionally, the RRM measurement result may also include one or more of the following: a measurement amount of a neighboring cell when the UE performs cell selection or reselection, a state of the UE corresponding to the measurement amount, a time corresponding to the measurement amount, and a cell identifier.

[0100] Among them, the UE status may include UE location, UE moving speed, and UE moving direction.

[0101] The measurement quantity of the cell is, for example, one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference and noise ratio (SINR), and received signal strength indication (RSSI). The cell identifier is, for example, one or more of a global cell identifier (CGI) and a physical cell identifier (PCI).

[0102] (3) Historical measurement configuration parameters (or current measurement configuration parameters) used by the UE when generating auxiliary information. The historical measurement configuration parameters may be pre-sent by the base station to the first UE. Optionally, the historical measurement configuration parameters may be at a cell granularity.

[0103] The historical measurement configuration parameters include, for example, one or more of the following: measurement frequency, neighbor cell identifier, measurement start threshold, measurement interval, measurement period, etc. Exemplarily, the measurement period is the period for the UE to read a neighbor cell synchronization signal block (SSB).

[0104] Furthermore, for neighboring cells of different priorities, and whether the neighboring cell and the serving cell are co-frequency or heterodyne, the value of the measurement start threshold of the neighboring cell may be different, specifically as follows:

[0105] When the priority of the neighboring cell is higher than that of the current serving cell, the UE starts measurement unconditionally, i.e., there is no measurement start threshold;

[0106] When the priority of the neighboring cell is the same as that of the current serving cell, if the neighboring cell and the serving cell are of the same frequency and Srxlev <= SIntraSearchP and Squal <= SIntraSearchQ are satisfied, the UE performs intra-frequency measurements. Therefore, the measurement start thresholds are SIntraSearchP and SIntraSearchQ. If the neighboring cell and the serving cell are of different frequencies and Srxlev <= SnonIntraSearchP and Squal <= SnonIntraSearchQ are satisfied, the UE performs measurements on NR inter-frequency cells. Therefore, the measurement start thresholds are SnonIntraSearchP and SnonIntraSearchQ.

[0107] When the priority of the neighboring cell is lower than that of the current serving cell, if Srxlev <= SnonIntraSearchP and Squal <= SnonIntraSearchQ are satisfied, the UE performs measurements on NR inter-frequencies or inter-RAT cells (inter-frequency measurements or inter-system measurements). Therefore, the measurement start thresholds are SnonIntraSearchP and SnonIntraSearchQ.

[0108] The descriptions of the parameters can be found in Table 1 below.

[0109] Table 1

[0110]

[0111] (4) The number of measurements during the period from when the UE starts measuring neighboring cells to when cell reselection ends. It can also be referred to as the average measurement times of the UE during network search, which is used to evaluate the efficiency of the UE for cell reselection or to evaluate the power consumption of the UE for cell reselection. Generally, the fewer the average measurement times of the UE during network search, the lower the power consumption of the UE measurement.

[0112] (5) The cell selection result of the UE. That is, whether the UE selects a suitable cell after power-on.

[0113] (6) The cell reselection result of the UE. That is, whether the UE reselects to a suitable cell. If the neighboring cell meets the reselection criteria, the UE will camp on the suitable cell (the UE is in the camped normally state). Otherwise, the UE is in the any cell selection or camped on any cell state.

[0114] Or,

[0115] (7) UE throughput information. For example, the average throughput of the UE accessing the network, or the change in the throughput of the UE accessing the network before and after the UE reselects a cell. The UE throughput information is mainly used to evaluate the effect of the measurement configuration parameters currently used by the UE. For example, whether the UE throughput (or link quality) is improved after the UE uses the current measurement configuration parameters.

[0116] It can be understood that the auxiliary information here is specifically the auxiliary information of the first UE, and the UE in the above parameters (1) to (7) is the first UE.

[0117] It can also be understood that the specific name of the parameter type included in the auxiliary information is not limited in the present application, and when a parameter type has the same function as a parameter type in the present application, it is also within the protection scope of the present application. This description also applies to the following embodiments.

[0118] 2. The first UE may send auxiliary information to the base station in the following manner:

[0119] Mode 1: The first UE reports the auxiliary information through a logged minimization of drive tests (logged MDT). That is, the logged MDT includes the auxiliary information, for example, the auxiliary information may be carried in a logMeasReport information element.

[0120] Exemplarily, the base station sends the first information to the first UE, and correspondingly, the first UE receives the first information from the base station. The first information includes the configuration information of logged MDT. Optionally, the first information can also be used to instruct the first UE to report auxiliary information through logged MDT. The configuration information of logged MDT in the first information is used to implicitly instruct the first UE to report auxiliary information through logged MDT. For example, the configuration information of logged MDT includes the relevant configuration of the first UE reporting auxiliary information, and the configuration information of logged MDT received by the first UE includes the relevant configuration of the first UE reporting auxiliary information, then the first UE reports the above auxiliary information through logged MDT. Alternatively, the first information also includes first indication information, and the first indication information is used to explicitly instruct the first UE to report auxiliary information through logged MDT. For example, the displayed indication information is a bool value, which takes a value of 0 or 1. When the value is 1, the first UE reports the first information. For example, the first information includes both the first indication information and the configuration information for reporting auxiliary information.

[0121] Exemplarily, the configuration information of Logged MDT includes measurement duration, measurement period, reporting type, etc. The measurement duration is the time range for the first UE to record the content of the measurement quantity. Within this time range, the first UE records and reports the measurement content according to the configuration. The reporting types include periodic reporting and event-triggered reporting. The measurement period is the time interval for recording and / or reporting measurement information. Periodic reporting means that the first UE periodically reports the measurement results within the measurement time range according to the configured period. If it is an event-triggered report, the first UE needs to meet the triggering condition (for example, eventL1) and record and report the measurement results according to the period.

[0122] Optionally, the first information may only indicate that the first UE reports auxiliary information through logged MDT. The first UE reports the auxiliary information according to the default parameter configuration. For example, the first UE may report parameter-related information (for example, the parameter type included in the auxiliary information) based on the protocol provisions or in advance with the base station. After receiving the first information, the first UE can know that the first UE needs to report auxiliary information through logged MDT, and the parameter type included in the auxiliary information. Optionally, the first information may only indicate that the first UE reports auxiliary information through logged MDT. The first UE determines the parameter type included in the auxiliary information by itself.

[0123] Optionally, the first information may also include configuration information corresponding to the reported auxiliary information. Exemplarily, the first information includes at least one of the following: a generation period, a measurement duration (the measurement duration is a time range for the first UE to report the auxiliary information. For example, when the measurement duration is configured to be infinite, the first UE will always collect and report the auxiliary information), information related to the reported parameters (for example, the parameter type included in the auxiliary information), etc. The first UE may generate logMeasReport according to the configuration information of logged MDT, and then report the logMeasReport to the base station.

[0124] Exemplarily, the first information may be a logged measurement configuration message.

[0125] Mode 2: The first UE reports the assistance information via UE assistance information. That is, the UE assistance information includes the assistance information.

[0126] Exemplarily, the base station sends the second information to the first UE, and correspondingly, the first UE receives the second information from the base station. The second information includes configuration information of UE assistance information. Optionally, the second information can also be used to instruct the first UE to report auxiliary information through UE assistance information. Exemplarily, the configuration information of UE assistance information in the second information is used to implicitly instruct the first UE to report auxiliary information through UE assistance information. For example, the configuration information of UE assistance information includes relevant configurations for the first UE to report auxiliary information, and the configuration information of UE assistance information received by the first UE includes relevant configurations for the first UE to report auxiliary information, then the first UE reports the above auxiliary information through UE assistance information. Alternatively, the second information also includes second indication information, and the second indication information is used to explicitly instruct the first UE to report auxiliary information through UE assistance information. For example, the second information includes both the first indication information and the configuration information for reporting auxiliary information.

[0127] Optionally, the configuration information of the UE assistance information includes information related to reporting parameters (for example, parameter types included in the assistance information), etc. The parameter types included in the assistance information may refer to the description in step 401.

[0128] Optionally, the second information includes a reporting type, and the reporting type may be an event-triggered reporting or a periodic reporting.

[0129] For event-triggered reporting, it may be that a parameter included in the auxiliary information has changed, for example, a parameter in the auxiliary information exceeds the threshold corresponding to the parameter, or multiple parameter changes exceed the thresholds corresponding to each parameter. It can be understood that different parameters correspond to different thresholds. The multiple thresholds may be configured by the base station, for example, they may be carried in the second information. Or the threshold may also be a default value, which is specified by the protocol. For example, if the change in the neighboring area RSRP measured by the first UE relative to the neighboring area RSRP reported last time exceeds the threshold corresponding to RSRP, the first UE is triggered to report the auxiliary information; or if it is specified that the change in certain parameters exceeds the threshold corresponding to each parameter, the first UE is triggered to report the auxiliary information, for example, if the configuration RSRP and the first UE position change both exceed their respective thresholds, the first UE is triggered to report the auxiliary information. The parameter types included in the auxiliary information listed in step 401 may be arbitrarily combined, and this application does not list them one by one. Optionally, for event-triggered reporting, if the first UE obtains a certain parameter for the first time, the reporting of the auxiliary information is triggered. The parameter change greater than the threshold also includes the following situations: new parameters are added, for example, the last reported auxiliary information does not contain a certain parameter (for example, the parameter cannot be obtained, or has not been generated, or a new parameter type is added), and the current auxiliary information obtains this parameter, then the parameter change is considered to be greater than the threshold.

[0130] For periodic reporting, the second information also carries a reporting period (or reporting time interval). The first UE periodically reports the auxiliary information according to the configured reporting time interval. Optionally, for periodic reporting, the first UE does not need to determine whether the auxiliary information has changed.

[0131] Optionally, the first UE may also report auxiliary information in combination with periodic reporting and event-triggered reporting. For example, the first UE periodically determines whether the auxiliary information has changed, and reports the auxiliary information if it has changed, otherwise does not report the auxiliary information.

[0132] Optionally, the second information may only instruct the first UE to report auxiliary information through UE assistance information. The first UE reports the auxiliary information according to the default parameter configuration. For example, the first UE may report parameter-related information (for example, the parameter type included in the auxiliary information) based on the protocol provisions or in advance with the base station. After receiving the second information, the first UE can know that the first UE needs to report auxiliary information through UE assistance information, and the parameter type included in the auxiliary information. Optionally, the second information may only instruct the first UE to report auxiliary information through UE assistance information. The first UE determines the parameter type included in the auxiliary information by itself.

[0133] Exemplarily, the second information may be an RRC configuration (RRC reconfiguration) message.

[0134] Further, when the first UE is in the RRC idle state, if the first UE determines that auxiliary information needs to be reported, the first UE may first enter the RRC connected state.

[0135] Example a: Once the first UE needs to report auxiliary information (such as generating logged MDT or UEassistance information), it initiates a random access process to the base station and then enters the RRC connection state. Optionally, the first UE sends a scheduling request to the base station, which is used to request uplink resources from the base station, and then the first UE reports auxiliary information based on the requested uplink resources.

[0136] Example b: After generating auxiliary information (such as generating logged MDT or UE assistance information), the first UE does not report the auxiliary information immediately. Instead, when it is necessary to transmit service data (such as uplink service data or downlink service data), it initiates a random access process to the base station. If the uplink resources are sufficient to send the auxiliary information, the auxiliary information is sent. If the uplink resources are insufficient to send the auxiliary information, the first UE also sends a scheduling request to the base station to request uplink resources, and reports the auxiliary information based on the uplink resources received by the request.

[0137] Step 402: The base station determines measurement configuration information according to the auxiliary information.

[0138] The measurement configuration information includes at least one set of measurement configuration parameters and at least one set of validity conditions of the measurement configuration parameters.

[0139] The base station generates N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters according to the auxiliary information (see Table 2 for details), where N is a positive integer. Exemplarily, N is an integer greater than 1. Subsequently, the base station combines the N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters into measurement configuration information.

[0140] Table 2

[0141] Effective conditions Measurement Configuration Parameters Effective Condition 1 Measurement configuration parameters 1 Effective Condition 2 Measurement Configuration Parameters 2 …… …… Effective Conditions N Measurement configuration parameter N

[0142] The measurement configuration parameters include but are not limited to one or more of the following parameter types: neighbor cell identifier, measurement frequency, measurement start threshold, measurement stop threshold, measurement interval, measurement cycle, measurement priority, or gain information.

[0143] The identifier of the neighboring cell is the identifier of the neighboring cell to be measured. Each neighboring cell may correspond to a measurement frequency point, and the measurement priority may specifically be the measurement priority of the neighboring cell, the measurement priority of the measurement frequency point, etc. The gain information includes one or more gain intervals and a probability interval corresponding to each gain interval, for example, it is expressed as that the UE has an x% probability of obtaining a y% gain.

[0144] In one possible example, the measurement configuration parameters include a neighbor list (list), and the neighbor list includes one or more neighbor identifiers. The neighbor identifier is, for example, CGI or PCI. Further, the measurement configuration parameters include at least one of the following: a measurement frequency corresponding to each neighbor, a measurement start threshold, a measurement stop threshold, a measurement interval, a measurement cycle, and a measurement priority. Alternatively, the measurement configuration parameters include at least one of the following: a measurement start threshold, a measurement stop threshold, a measurement interval, a measurement cycle, and a measurement priority corresponding to each measurement frequency.

[0145] Alternatively, in other possible examples, multiple neighboring cells may correspond to the same measurement frequency, or multiple neighboring cells correspond to the same measurement start threshold, or multiple neighboring cells correspond to the same measurement stop threshold, or multiple neighboring cells correspond to the same measurement interval, or multiple neighboring cells correspond to the same measurement priority, etc. For example, the neighboring cell list includes cells 1 to 5, wherein cells 1 and 2 correspond to the same measurement frequency, cells 1 and 3 correspond to the same measurement start threshold, cells 1 and 4 correspond to the same measurement stop threshold, cells 1 and 5 correspond to the same measurement interval, cells 2 and 5 correspond to the same measurement priority, etc.

[0146] The effective condition includes, but is not limited to, one or more of the following parameter types: area information, mobile information, or an effective period corresponding to the measurement configuration parameter. Among them, the area information is, for example, a geographical area, a cell identifier, etc. For example, the geographical area can be an area determined by a reference position and a radius, or an area determined by a regional boundary, or an area determined by a boundary line; the area information can also be a set of cell identifiers, that is, an area represented by a cell identifier, or an area represented by a mapped cell identifier (mapped cell ID), wherein the geographical area corresponding to the mapped cell ID is smaller than the geographical area corresponding to the cell identifier, and the mapping relationship between the mapped cell ID and the geographical area can be determined by the base station. The mobile information includes, for example, one or more of the moving speed and the moving direction. Optionally, the moving speed can be a value or a range; the moving direction can be a value or a range. The effective period includes, for example, one or more of the effective deadline, the starting time, the remaining effective time, and the effective duration. If the current time is within the effective period corresponding to the measurement configuration parameter, the measurement configuration parameter is effective. If the current time is outside the effective period corresponding to the measurement configuration parameter, the measurement configuration parameter is not effective (or invalid).

[0147] In one possible example, an AI model is deployed in the base station, and the AI ​​model is used to infer N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters according to the auxiliary information. Exemplarily, the base station inputs the received auxiliary information into the AI ​​model, and then obtains the N sets of measurement configuration parameters output by the AI ​​model and the effectiveness conditions corresponding to the N sets of measurement configuration parameters.

[0148] In another possible example, an AI model is deployed in OAM, and the AI ​​model is used to infer N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters based on the auxiliary information. Exemplarily, the base station sends the received auxiliary information to OAM, and OAM inputs the auxiliary information into the AI ​​model, thereby obtaining the N sets of measurement configuration parameters output by the AI ​​model and the effectiveness conditions corresponding to the N sets of measurement configuration parameters. Subsequently, OAM sends the N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters to the base station. In addition, the AI ​​model can also be deployed in the core network equipment. For this implementation method, please refer to the implementation method of deploying the AI ​​model in OAM.

[0149] Furthermore, the base station can also obtain the status information of the second UE, determine the measurement configuration parameters corresponding to the status information of the second UE according to the status information of the second UE, N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters, and use the determined measurement configuration parameters and the effectiveness conditions of the measurement configuration parameters as the measurement configuration information.

[0150] Among them, the first UE is a UE that reports auxiliary information, and the second UE is a UE that receives measurement configuration information. The first UE is one or more, and the second UE can also be one or more. It should be pointed out that for a certain UE, the UE can report auxiliary information to the base station based on historical measurement configuration parameters, and can also receive new measurement configuration information from the base station; or, the UE is only used to report auxiliary information to the base station based on historical measurement configuration parameters, or, the UE is only used to receive new measurement configuration information from the base station.

[0151] The status information of the second UE includes one or more of the following: movement information of the second UE (such as the movement speed of the second UE, the movement direction of the second UE, etc.), location information of the second UE (such as the geographical location, the cell identifier, etc.).

[0152] When the base station determines the measurement configuration parameters corresponding to the state information of the second UE, specifically, the base station may select n sets of measurement configuration parameters that are in effect from the N sets of measurement configuration parameters according to the effective time periods corresponding to the N sets of measurement configuration parameters, where n is an integer less than or equal to N. Subsequently, the base station selects measurement configuration parameters whose area information includes the location information of the second UE, whose speed interval includes the moving speed of the second UE, and whose moving direction is the same as the moving direction of the second UE from the n sets of measurement configuration parameters according to the location information, speed interval and moving direction corresponding to the n sets of measurement configuration parameters, and then uses the selected measurement configuration parameters as the measurement configuration parameters corresponding to the state information of the second UE. In combination with the example in Table 2 above, effective condition 1 includes real geographical area 1, speed interval 1, moving direction 1, and effective time period 1, effective condition 2 includes real geographical area 1, speed interval 2, moving direction 2, and effective time period 2, and effective condition 3 includes real geographical area 3, speed interval 3, moving direction 3, etc. The geographical location in the status information of the second UE is located in the real geographical area 1, the moving direction in the status information of the second UE matches the moving direction 1, and the moving speed in the status information of the second UE is located in the moving interval 1, and the current time is located in the effective time period 1, then the base station can determine that the measurement configuration parameter 1 corresponding to the effective condition 1 is the measurement configuration parameter corresponding to the status information of the second UE, and then the measurement configuration parameter 1 can be used as the measurement configuration information.

[0153] The base station may also directly generate measurement configuration parameters that match the state information of the second UE without selecting one from the N groups of measurement configuration parameters according to the state information of the second UE. Specifically, the base station generates measurement configuration parameters corresponding to the state information of the second UE and the effectiveness conditions corresponding to the measurement configuration parameters according to the auxiliary information and the state information of the second UE. It can be understood that if the second UE determines that the effectiveness conditions are not met according to the current state information of the second UE and the effectiveness conditions corresponding to the measurement configuration parameters, this group of measurement configuration parameters will not be effective.

[0154] When the base station acquires the status information of the second UE, specifically, the second UE sends a measurement configuration request to the base station, and correspondingly, the base station receives the measurement configuration request from the second UE, where the measurement configuration request includes the status information of the second UE.

[0155] Step 403: The base station sends measurement configuration information. Correspondingly, the second UE receives the measurement configuration information from the base station.

[0156] Mode 1: The base station sends a broadcast message, the broadcast message includes measurement configuration information, the measurement configuration information includes N sets of measurement configuration parameters and effectiveness conditions corresponding to the N sets of measurement configuration parameters. Correspondingly, the second UE receives the broadcast message.

[0157] Optionally, the second UE may also send a first request message to the base station, where the first request message is used to request system information, for example, a system information block (SIB) for requesting measurement configuration information. Exemplarily, the first request message may be carried in MSG1 or MSG3. In response to the first request message, the base station sends a broadcast message, where the broadcast message carries the measurement configuration information.

[0158] Example 1: The measurement configuration information may be carried in an existing SIB, such as SIB2, SIB3, and SIB4. For example, the base station broadcasts SIB2, which carries the measurement configuration information. Accordingly, the second UE receives SIB2 and obtains the measurement configuration information from SIB2.

[0159] Example 2, defining a new SIB (e.g., SIB x), which carries measurement configuration information. For example, the base station broadcasts SIB x, and correspondingly, the second UE receives SIB x and obtains measurement configuration information from SIB x. In Example 2, it can be implemented that only UEs that support this feature read SIB x. Specifically, the UE reads the scheduling information of SIBx in SIB1, and further reads SIBx if the UE capability supports this feature; illustratively, the UE capability refers to whether the UE supports measurement configuration enhancement capability. This capability can be reported by the UE to the base station, or can be obtained by the base station from the core network; if the UE does not support this feature, or the UE does not have the capability, the UE does not read SIBx.

[0160] In addition, in order to further reduce power consumption of the second UE in reading SIB x, the second UE may read SIB x when current measurement configuration information (such as legacy measurement configuration information or last enhanced measurement configuration information) fails or when the current measurement configuration information is unavailable.

[0161] It can be understood that the measurement configuration information here is enhanced measurement configuration information performed by the base station.

[0162] For the convenience of description, unless otherwise specified, the “measurement configuration information” in the following description refers to “enhanced measurement configuration information”.

[0163] Possible mode 2: the base station sends measurement configuration information to the second UE via RRC dedicated signaling. Correspondingly, the second UE receives the measurement configuration information from the base station via RRC dedicated signaling, wherein the RRC dedicated signaling is, for example, an RRCreconfiguration message.

[0164] In one example, the base station sends measurement configuration information to the second UE through RRC dedicated signaling, and the measurement configuration information includes N sets of measurement configuration parameters and effectiveness conditions corresponding to the N sets of measurement configuration parameters. Optionally, before sending the measurement configuration information to the second UE through RRC dedicated signaling, the base station may first obtain the identifiers of one or more UEs subscribed to the measurement configuration information from a core network device (such as unified data management (UDM)), wherein the one or more UEs include the second UE.

[0165] Optionally, if the second UE sends a measurement configuration request to the base station, the base station sends measurement configuration information to the second UE via RRC dedicated signaling. The measurement configuration information includes N sets of measurement configuration parameters and effectiveness conditions corresponding to the N sets of measurement configuration parameters.

[0166] Optionally, before sending the measurement configuration information to the second UE through RRC dedicated signaling, the base station may first obtain information about the second UE subscribing to the enhanced feature from the core network device. If the base station determines that the second UE has subscribed to the enhanced feature, the base station sends the measurement configuration information to the second UE.

[0167] Optionally, before sending measurement configuration information to the second UE through RRC dedicated signaling, the base station may first obtain a capability indication of whether the second UE supports the feature. The base station may obtain a capability indication of whether the second UE supports the feature from a core network device (e.g., an access and mobility management function (AMF)), or the base station may obtain a capability indication of whether the second UE supports the feature from a UE radio capability reported by the second UE.

[0168] In another example, the base station sends measurement configuration information to the second UE through RRC dedicated signaling, and the measurement configuration information includes measurement configuration parameters corresponding to the state information of the second UE, and the validity conditions of the measurement configuration parameters. Optionally, before sending the measurement configuration information to the second UE through RRC dedicated signaling, the base station may first receive a measurement configuration request from the second UE, and the measurement configuration request includes the state information of the second UE, and the details can be seen in the description of the above step 402.

[0169] Optionally, when the second UE determines that the current measurement configuration information (such as legacy measurement configuration information or last enhanced measurement configuration information) is invalid, or the current measurement configuration information is unavailable, the invalid or unavailable measurement configuration information is deleted. Further, the second UE sends a measurement configuration request to the base station.

[0170] It should be added that if the second UE receives both legacy measurement configuration information and enhanced measurement configuration information, the enhanced configuration information is used preferentially. Specifically, the second UE may use all enhanced configuration information, or use part of the enhanced configuration information and the rest of the legacy measurement configuration information. If the second UE determines that the currently used enhanced measurement configuration information is expired or unavailable (for example, the effective conditions cannot be matched, such as UE position mismatch, UE speed mismatch, effective period mismatch), the legacy measurement configuration information is used.

[0171] Step 404: The second UE performs cell measurement according to the measurement configuration information.

[0172] Mode a, when the measurement configuration information includes N sets of measurement configuration parameters and the effective conditions corresponding to the N sets of measurement configuration parameters, the second UE determines the state information of the second UE, and then determines the measurement configuration parameters corresponding to the state information of the second UE according to the state information of the second UE, the N sets of measurement configuration parameters and the effective conditions corresponding to the N sets of measurement configuration parameters. For specific implementation, refer to the description of the base station determining the measurement configuration parameters corresponding to the state information of the second UE in step 402. Further, the second UE performs cell measurement according to the selected measurement configuration parameters corresponding to the state information of the second UE.

[0173] Mode b: When the measurement configuration information includes measurement configuration parameters corresponding to the state information of the second UE, the second UE may directly perform measurement according to the measurement configuration parameters in the measurement configuration information. For example, the measurement configuration information includes a set of measurement configuration parameters. Alternatively, the measurement configuration information includes a set of measurement configuration parameters and corresponding validity conditions. After determining that the current state information of the second UE matches the validity conditions of the measurement configuration parameters, the second UE performs measurement according to the measurement configuration parameters.

[0174] Optionally, after performing cell measurement according to the measurement configuration information, the second UE may obtain an RRM measurement result. The second UE performs cell reselection according to the RRM measurement result.

[0175] Optionally, the second UE further generates new auxiliary information according to the RRM measurement result or the cell reselection result, and sends the new auxiliary information to the base station, wherein the parameter type included in the new auxiliary information may be the same as the parameter type included in the auxiliary information in step 401, or the parameter type included in the new auxiliary information is part of the parameter type included in the auxiliary information in step 401, such as including the cell reselection result of the UE, the number of measurements made by the UE in the period from the start of the neighboring cell measurement to the end of the cell reselection, the throughput information of the UE, etc. Alternatively, it includes an indication of whether the UE uses the enhanced measurement configuration parameter configured by the base station, and the indication may be a Boolean value, taking a value of 0 or 1. It can be understood that the auxiliary information here is specifically the auxiliary information of the second UE, and the UE in the above parameters (1) to (7) is the second UE.

[0176] Optionally, in the scenario where the AI ​​model is included in the base station, the base station may also optimize the AI ​​model according to the new auxiliary information after receiving the new auxiliary information from the second UE. In the scenario where the AI ​​model is included in OAM, the base station may also send new auxiliary information to OAM after receiving the new auxiliary information from the second UE, and OAM optimizes the AI ​​model according to the new auxiliary information. The scenario where the AI ​​model is included in the core network device is similar to the scenario where the AI ​​model is included in OAM. Among them, the AI ​​model is optimized, for example, by updating the model parameters, model structure, etc. in the AI ​​model.

[0177] In a possible manner, the second UE performs measurement according to the measurement configuration parameter corresponding to the state information of the second UE, as follows:

[0178] The second UE needs to consider two parameters when initiating neighboring cell measurement: cell priority and signal quality of the serving cell.

[0179] Specifically, when the priority of the neighboring cell is higher than that of the current serving cell, the second UE starts measurement unconditionally; when the priority of the neighboring cell is the same as that of the current serving cell, or when the priority of the neighboring cell is lower than that of the current serving cell, the second UE compares the measured signal quality of the currently resident serving cell with the measurement start threshold sent by the base station. If the second UE determines that the signal quality of the currently resident serving cell is higher than the measurement start threshold, the neighboring cell measurement is not started; if the second UE determines that the signal quality of the currently resident serving cell is lower than or equal to the measurement start threshold, the neighboring cell measurement is started.

[0180] Further, the second UE may determine whether to perform cell reselection according to the signal quality of the neighboring cell. Still based on the priority of the serving cell and the neighboring cell, the following description is given:

[0181] (1) When the priority of the neighboring cell is higher than that of the current serving cell:

[0182] If threshServingLowQ is broadcasted in SIB2 and more than 1 second has elapsed since the second UE started camping on the current serving cell, cell reselection to an NR frequency or inter-RAT frequency with higher priority than the serving frequency shall be performed if:

[0183] The cell with higher priority NR or EUTRAN RAT / frequency is selected in the time interval Treselection RAT During this period, the following conditions are met: The current serving cell signal quality Squal> the high priority cell reselection threshold Thresh X,HighQ ;

[0184] Otherwise, cell reselection to an NR frequency or inter-RAT frequency with higher priority than the serving frequency shall be performed in the following cases:

[0185] The cell with higher priority RAT / frequency is selected in the time interval Treselection RAT During this period, the current serving cell signal quality Srxlev>Thresh X,HighP ; The second UE stays in the current serving cell for more than 1 second.

[0186] (2) When the priority of the neighboring cell is the same as that of the current serving cell:

[0187] The reselection of cells with the same priority is based on the R criterion. The so-called R criterion is to calculate the R value of each neighboring cell and the current serving cell based on the cell signal quality. The calculation method is as follows:

[0188] Rs=Qmeas,s+Qhyst-Qoffsettemp

[0189] Rn=Qmeas,n-Qoffset-Qoffsettemp

[0190] Then sort them according to the R value, that is, select the best cell according to the R value.

[0191] a. The cell needs to meet the S criterion, which is Srxlev>0AND Squal>0.

[0192] Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp

[0193] Squal=Qqualmeas-(Qqualmin+Qqualminoffset)-Qoffsettemp;

[0194] If rangeToBestCell is not configured, the second UE selects the cell with the highest R value as the target cell;

[0195] If rangeToBestCell is configured, find the maximum R value and all cells whose R values ​​fall within the range of the maximum R value rangeToBestCell, and select the cell with the largest number of beams exceeding the threshold (ieabsThreshSS-BlocksConsolidation) as the target cell; if there are multiple cells with the largest number of beams exceeding the threshold, select the cell with the largest R value as the target cell.

[0196] If the target cell selected by the above steps is not the current serving cell, determine whether the target cell meets the following conditions:

[0197] If the target cell is not the current serving cell and the following conditions are met, the second UE reselects to the cell; otherwise, the second UE continues to reside in the original serving cell:

[0198] The target cell continues to meet the cell reselection criteria in the above steps during TreselectionNR;

[0199] The second UE stays in the current serving cell for more than 1 second.

[0200] (3) When the priority of the neighboring cell is lower than that of the current serving cell:

[0201] If threshServingLowQ is broadcasted in SIB2 and more than 1 second has elapsed since the second UE camped on the current serving cell, cell reselection to an NR frequency or inter-RAT frequency cell with lower priority than the serving frequency shall be performed if:

[0202] The serving cell meets Squal <Thresh Serving,LowQ

[0203] Lower priority NR or EUTRAN RAT / frequency cells in time interval Treselection RAT During the period, Squal>Thresh X,LowQ .

[0204] Otherwise, cell reselection to an NR frequency or inter-RAT frequency cell with lower priority than the serving frequency shall be performed in the following cases: the serving cell satisfies Srxlev <Thresh Serving,LowP ; Lower priority RAT / frequency cells in time interval Treselection RAT During the period, Srxlev>Thresh X,LowP ; and more than 1 second has passed since the second UE camped on the current serving cell.

[0205] The description of each parameter can be found in Table 3 below.

[0206] Table 3

[0207]

[0208] In the above technical solution, the first UE generates auxiliary information based on historical measurement configuration parameters and reports the auxiliary information to the base station. Accordingly, the base station (or OAM) can generate measurement configuration information based on the auxiliary information, and the measurement configuration information includes at least one measurement configuration parameter and an effective condition of at least one measurement configuration parameter, wherein the measurement configuration information includes a measurement configuration parameter whose effective condition is adapted to the status information of the second UE. When the second UE uses the measurement configuration parameter whose effective condition is adapted to the status information of the second UE to perform cell measurement, it helps to improve the efficiency of cell measurement and reduce the measurement power consumption of the second UE.

[0209] like Figure 5 A flow chart of the second communication method provided for this application:

[0210] Step 501: A first UE sends auxiliary information of the first UE to a base station, and correspondingly, the base station receives the auxiliary information from the first UE.

[0211] For the description of the auxiliary information, please refer to the description in step 401.

[0212] Step 502: The second UE sends a measurement configuration request to the base station, where the measurement configuration request includes state information of the second UE.

[0213] The first UE is a UE that reports auxiliary information, and the second UE is a UE that receives measurement configuration information. The first UE is one or more, and the second UE can also be one or more. For details, refer to the description in step 402.

[0214] For details about the status information of the second UE, please refer to the description in step 402.

[0215] Step 503: The base station determines measurement configuration information according to the auxiliary information of the first UE and the state information of the second UE, wherein the measurement configuration information includes measurement configuration parameters corresponding to the state information of the second UE.

[0216] In one possible manner, the base station determines N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters respectively according to the auxiliary information of the first UE. For specific implementation, refer to the description in step 402. Further, the base station determines the measurement configuration parameters corresponding to the state information of the second UE according to the state information of the second UE, the N sets of measurement configuration parameters, and the effectiveness conditions corresponding to the N sets of measurement configuration parameters respectively, and uses the measurement configuration parameters corresponding to the state information of the second UE as the measurement configuration information. For specific implementation of the base station determining the measurement configuration parameters corresponding to the state information of the second UE, refer to the description in step 402.

[0217] In another possible manner, the base station generates a measurement configuration parameter corresponding to the state information of the second UE according to the auxiliary information and the state information of the second UE, and uses the measurement configuration parameter corresponding to the state information of the second UE as the measurement configuration information. For the description of the state information and measurement configuration parameter of the second UE, please refer to the description in step 402.

[0218] In one possible example, an AI model is deployed in the base station, and the AI ​​model is used to infer the measurement configuration parameters corresponding to the state information of the second UE based on the auxiliary information and the state information of the second UE. Exemplarily, the base station inputs the received auxiliary information and the state information of the second UE into the AI ​​model, and then obtains the measurement configuration parameters corresponding to the state information of the second UE output by the AI ​​model.

[0219] In another possible example, an AI model is deployed in OAM, and the AI ​​model is used to infer the measurement configuration parameters corresponding to the status information of the second UE based on the auxiliary information and the status information of the second UE. Exemplarily, the base station sends the auxiliary information and the status information of the second UE to OAM, and OAM inputs the auxiliary information and the status information of the second UE into the AI ​​model, thereby obtaining the measurement configuration parameters corresponding to the status information of the second UE output by the AI ​​model. Subsequently, OAM sends the measurement configuration parameters corresponding to the status information of the second UE to the base station. In addition, the AI ​​model can also be deployed in the core network equipment, and the implementation method can refer to the implementation method of deploying the AI ​​model in OAM.

[0220] Step 504: The base station sends measurement configuration information to the second UE, and correspondingly, the second UE receives the measurement configuration information from the base station.

[0221] In one example, the base station sends measurement configuration information to the second UE through RRC dedicated signaling, where the measurement configuration information includes measurement configuration parameters corresponding to the state information of the second UE, and the second UE subscribes to the measurement configuration information.

[0222] Step 505: The second UE performs cell measurement according to the measurement configuration information.

[0223] Optionally, after the second UE performs cell measurement according to the measurement configuration parameters in the measurement configuration information, it can obtain the RRM measurement result. The second UE performs cell reselection according to the RRM measurement result. Optionally, the second UE also generates new auxiliary information based on the RRM measurement result, and sends the new auxiliary information to the base station. Optionally, the network side (base station, OAM or core network equipment) can also optimize the AI ​​model based on the new auxiliary information from the second UE. For details, please refer to the description in step 404.

[0224] For specific implementation of the second UE performing cell measurement (starting neighboring cell measurement, performing cell reselection, etc.) according to the measurement configuration information, refer to the description in step 404.

[0225] In the above technical solution, the first UE generates auxiliary information of the first UE according to the historical measurement configuration parameters, and reports the auxiliary information of the first UE to the base station. When the second UE needs to obtain the measurement configuration parameters corresponding to the state information of the second UE, it can send a measurement configuration request to the base station, and the measurement configuration request includes the measurement configuration parameters corresponding to the state information of the second UE. Subsequently, the base station can generate the measurement configuration parameters corresponding to the state information of the second UE according to the auxiliary information of the first UE and the state information of the second UE, and send the measurement configuration parameters corresponding to the state information of the second UE as the measurement configuration information to the second UE. The second UE performs cell measurement according to the measurement configuration parameters corresponding to the state information of the second UE, which helps to improve the efficiency of the second UE in performing cell measurement and reduce the power consumption of the second UE.

[0226] like Figure 6 A flowchart of the third communication method provided in this application.

[0227] Step 601: The first UE determines first measurement configuration information according to auxiliary information.

[0228] In a specific implementation, the first UE generates auxiliary information according to historical measurement configuration parameters, and then determines the first measurement configuration information according to the auxiliary information.

[0229] The historical measurement configuration parameters include one or more of the following: measurement frequency, neighboring cell identifier, measurement start threshold, measurement interval, or measurement cycle, etc. For details, please refer to the description in step 401.

[0230] The auxiliary information includes one or more of the following parameter types (1) to (7): (1) RRM measurement results when the UE performs cell selection. (2) RRM measurement results when the UE performs cell reselection. (3) Historical measurement configuration parameters used by the UE when generating auxiliary information. (4) The number of measurements made by the UE from the start of neighboring cell measurement to the end of cell reselection. (5) Cell selection results of the UE. (6) Cell reselection results of the UE. (7) Throughput information of the UE. For detailed descriptions of parameter types (1) to (7), please refer to the description in step 401.

[0231] The first measurement configuration information includes the state information of the first UE and the measurement configuration parameters corresponding to the state information of the first UE, or the first measurement configuration information includes at least one set of measurement configuration parameters and the effectiveness condition of at least one set of measurement configuration parameters.

[0232] The state information of the first UE includes one or more of the following: mobility information of the first UE and location information of the first UE, for details, refer to the description in step 402. The measurement configuration parameters include at least one of the following: a measurement frequency corresponding to each neighboring area, a measurement start threshold, a measurement stop threshold, a measurement interval, a measurement cycle, and a measurement priority, for details, refer to the description in step 402. The effectiveness condition includes at least one of the following: area information, mobility information, or an effective period corresponding to the measurement configuration parameter, for details, refer to the description in step 402.

[0233] In method (1), the first UE generates N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters according to the auxiliary information, where N is a positive integer, and illustratively, N is an integer greater than 1. The first UE combines the N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters into first measurement configuration information.

[0234] In one possible example, an AI model is deployed in the first UE, and the AI ​​model is used to infer N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters according to the auxiliary information. Exemplarily, the first UE inputs the auxiliary information into the AI ​​model, and then obtains the N sets of measurement configuration parameters output by the AI ​​model and the effectiveness conditions corresponding to the N sets of measurement configuration parameters.

[0235] Furthermore, the first UE may also determine the measurement configuration parameters corresponding to the state information of the first UE based on the state information and auxiliary information of the first UE. In a specific implementation, the first UE may also obtain the state information of the first UE, and determine the measurement configuration parameters corresponding to the state information of the first UE based on the state information of the first UE, N sets of measurement configuration parameters, and the effectiveness conditions corresponding to the N sets of measurement configuration parameters. Subsequently, the first UE performs cell measurement based on the measurement configuration parameters corresponding to the state information of the first UE.

[0236] Mode (ii): The first UE generates measurement configuration parameters corresponding to the state information of the first UE based on the auxiliary information and the state information of the first UE, and uses the measurement configuration parameters corresponding to the state information of the first UE as the first measurement configuration information. Here, the first measurement configuration information can be considered as the measurement configuration parameters recommended by the first UE. Optionally, the first measurement configuration information also includes the state information of the first UE, and the first UE state information includes at least one of the following: UE position, UE moving speed, and UE moving direction. Furthermore, the first UE also performs cell measurement based on the first measurement configuration information.

[0237] Optionally, in method (1) and method (2), the first measurement configuration information generated by the first UE may also include a network search result, and the parameter type included in the network search result may be part or all of the parameter types included in the auxiliary information.

[0238] Exemplarily, the network search result includes at least one of the following parameter types: the configuration parameters currently used by the UE (i.e., historical measurement configuration parameters), the RRM measurement results when the UE performs cell reselection, the average number of UE network search measurements, the UE's cell reselection results, and the UE's throughput information. For specific instructions, please refer to the description of the parameter types included in the auxiliary information in step 401.

[0239] Optionally, the network search result also includes third indication information, and the third indication information is used to indicate whether the configuration parameters currently used by the UE are appropriate. The third indication information can be of bool type, with a value of 1 or 0. When the third indication information has a value of 1, it indicates that the configuration parameters currently used by the UE are reasonable, and the base station does not need to adjust the measurement configuration parameters. When the third indication information has a value of 0, it indicates that the configuration parameters currently used by the UE are unreasonable, and the base station needs to adjust the measurement configuration parameters. Optionally, the third indication information may include multiple indications, and the multiple indications can be used to indicate whether the values ​​of the corresponding parameter types are reasonably configured. For example, different indications are defined in the third indication information, which can be used to indicate whether the values ​​of parameters such as the start-up threshold and the measurement interval are reasonably configured.

[0240] In one possible example, an AI model is deployed in the first UE, and the AI ​​model is used to infer the measurement configuration parameters corresponding to the UE's state information based on the auxiliary information and the UE's state information. Exemplarily, the first UE inputs the auxiliary information and the first UE's state information into the AI ​​model, and then obtains the measurement configuration parameters corresponding to the first UE's state information output by the AI ​​model, and uses the measurement configuration parameters corresponding to the first UE's state information as the first measurement configuration information.

[0241] Step 602: The first UE sends first measurement configuration information to a base station.

[0242] The first UE may send the first measurement configuration information to the base station in the following manner:

[0243] Mode (1): The first UE reports the first measurement configuration information through logged MDT. That is, the logged MDT includes the first measurement configuration information. For example, the first measurement configuration information may be carried in a logMeasReport information element.

[0244] Exemplarily, the base station sends first information to the first UE, and the first information includes configuration information of logged MDT. The first information can be used to instruct the first UE to report the first measurement configuration information through logged MDT. Optionally, the configuration information of logged MDT in the first information is used to implicitly instruct the first UE to report the first measurement configuration information through logged MDT. Alternatively, the first information also includes first indication information, and the first indication information is used to explicitly instruct the first UE to report the first measurement configuration information through logged MDT.

[0245] Exemplarily, the configuration information of Logged MDT includes but is not limited to: the generation interval of measurement configuration information, the reporting type, etc. Among them, the generation interval of measurement configuration information is used to indicate the time interval for the first UE to generate measurement configuration information. It can be considered that the first UE periodically generates measurement configuration information. The reporting types include periodic reporting and event-triggered reporting.

[0246] Optionally, the first information may only indicate that the first UE reports the first measurement configuration information through logged MDT. The first UE reports the first measurement configuration information according to the default parameter configuration. For example, the first UE may report parameter-related information based on the protocol provisions or in advance with the base station. After receiving the first information, the first UE can know that the first UE needs to report the first measurement configuration information through logged MDT, and the parameter type included in the first measurement configuration information. Optionally, the first information may also include configuration information corresponding to the reported first measurement configuration information. Exemplarily, the first information includes information related to the reported parameters. The reported parameter-related information includes the content of the reported parameters. For details, refer to the description of the parameter type included in the first measurement configuration information in step 601. The first UE can generate logMeasReport based on the configuration information of logged MDT, and then report logMeasReport to the base station.

[0247] Exemplarily, the first information may be a log measurement configuration message.

[0248] For the contents not described in detail in this application, please refer to the method 1 in the above sub-step 401. Specifically, the "auxiliary information" in the method 1 can be replaced with "first measurement configuration information" for understanding.

[0249] In mode (2), the first UE reports the first measurement configuration information through UE assistance information. That is, the UE assistance information includes the first measurement configuration information. For specific implementation, please refer to mode 2 in step 401 above.

[0250] Exemplarily, the base station sends second information to the first UE, and the second information includes configuration information of UE assistance information. Optionally, the second information is used to instruct the first UE to report the first measurement configuration information through UE assistance information. Among them, the configuration information of UE assistance information in the second information is used to implicitly instruct the first UE to report the first measurement configuration information through UE assistance information. Alternatively, the second information also includes second indication information, and the second indication information is used to explicitly instruct the first UE to report the first measurement configuration information through UE assistance information.

[0251] Optionally, the configuration information of the UE assistance information includes reporting parameter related information (for example, parameter types included in the first measurement configuration information), etc. The parameter types included in the first measurement configuration information may refer to the description in step 601.

[0252] Optionally, the second information includes a reporting type, and the reporting type may be an event-triggered reporting or a periodic reporting.

[0253] For event-triggered reporting, it may be that a parameter included in the first measurement configuration information has changed, for example, a parameter in the first measurement configuration information exceeds the threshold corresponding to the parameter, or multiple parameter changes exceed the thresholds corresponding to each parameter. It can be understood that different parameters correspond to different thresholds. The multiple thresholds may be configured by the base station, for example, they may be carried in the second information. Or the threshold may also be a default value, which is specified by the protocol. For example, if the change in the measurement start threshold exceeds the threshold corresponding to the measurement start threshold, the first UE is triggered to report the first measurement configuration information; or, it is specified that the change in certain parameters exceeds the threshold corresponding to each parameter to trigger the first UE to report the first measurement configuration information, for example, if the measurement start threshold and the measurement interval change are configured to exceed their respective thresholds, the first UE is triggered to report the first measurement configuration information. The parameters listed in step 601 may be arbitrarily combined, and this application does not list them one by one. Optionally, for event-triggered reporting, if the first UE obtains a certain parameter for the first time, the reporting of the first measurement configuration information is triggered. The parameter change greater than the threshold also includes the following situations: new parameters are added, for example, the first measurement configuration information reported last time does not contain a certain parameter (for example, the parameter cannot be obtained, or has not been generated, or a new parameter type is added), and the current first measurement configuration information obtains this parameter, then the parameter change is considered to be greater than the threshold.

[0254] For periodic reporting, the second information also carries a reporting period (or reporting time interval). The first UE periodically reports the first measurement configuration information according to the configured time interval. Optionally, for periodic reporting, the first UE does not need to determine whether the first measurement configuration information has changed.

[0255] Optionally, the first UE may also report the first measurement configuration information in combination with periodic reporting and event-triggered reporting. For example, the first UE periodically determines whether the first measurement configuration information has changed. If the first measurement configuration information has changed, the first measurement configuration information is reported; otherwise, the first measurement configuration information is not reported.

[0256] In method (3), the UE sends the first measurement configuration information as uplink data to the base station.

[0257] Optionally, when the UE generates the first measurement configuration information, or when the UE determines that a parameter in the first measurement configuration information is updated, the UE sends the first measurement configuration information to the base station.

[0258] Exemplarily, the UE determines that a parameter in the first measurement configuration information is updated, which may be that a parameter in the first measurement configuration information exceeds a threshold corresponding to the parameter, or that changes in multiple parameters exceed thresholds corresponding to each parameter. It can be understood that different parameters correspond to different thresholds. The multiple thresholds may be configured by the base station, or the threshold may be a default value, which is specified by the protocol. For example, if the change in the measurement start threshold exceeds the threshold corresponding to the measurement start threshold, the first UE is triggered to report the first measurement configuration information; or, it is specified that the change in certain parameters exceeds the threshold corresponding to each parameter to trigger the first UE to report the first measurement configuration information, for example, if the measurement start threshold and the measurement interval change are both configured to exceed their respective thresholds, the first UE is triggered to report the first measurement configuration information. The parameters listed in step 601 may be arbitrarily combined, and are not listed one by one in this application. Optionally, if the first UE obtains a certain parameter for the first time, reporting of the first measurement configuration information is triggered. The parameter change greater than the threshold also includes the following situations: new parameters are added, for example, the first measurement configuration information reported last time does not contain a certain parameter (for example, the parameter cannot be obtained, or has not been generated, or a new parameter type is added), and the current first measurement configuration information obtains this parameter, then the parameter change is considered to be greater than the threshold.

[0259] Further, when the first UE is in the RRC idle state, if the first UE determines that it is necessary to report or send the first measurement configuration information, the first UE may first enter the RRC connected state.

[0260] Example (a), once the first UE needs to report the first measurement configuration information (such as generating logged MDT, or UE assistance information, or sending the first measurement configuration information as uplink data), it initiates a random access process to the base station (or synchronizes with the base station through a random access-free process), and then enters the RRC connection state. Optionally, the first UE sends a scheduling request to the base station, the scheduling request is used to request uplink resources from the base station, and then the first UE reports the first measurement configuration information based on the requested uplink resources.

[0261] Example (b), after generating the first measurement configuration information (such as generating logged MDT, or UE assistance information, or sending the first measurement configuration information as uplink data), the first UE does not immediately report the first measurement configuration information. Instead, when service data (such as uplink service data or downlink service data) needs to be transmitted, a random access process is initiated to the base station (or synchronization with the base station is achieved through a random access-free process). If the uplink resources are sufficient to send the first measurement configuration information, the first measurement configuration information is sent. If the uplink resources are insufficient to send the first measurement configuration information, the first UE also sends a scheduling request to the base station to request uplink resources, and reports the first measurement configuration information based on the uplink resources requested.

[0262] Step 603: The base station determines second measurement configuration information according to the first measurement configuration information.

[0263] The first UE may be one or more. The base station may determine the second measurement configuration information according to the first measurement configuration information of the one or more first UEs.

[0264] For example, the network search result reported by the first UE shows that the measurement threshold configured by the base station for the first UE is too high. The base station can refer to the network search result when configuring parameters and lower the measurement threshold. For example, the network search result reported by the first UE includes the cell reselection result, the historical measurement configuration parameters used by the first UE corresponding to the cell reselection result, the average number of network search measurements of the first UE, and the throughput information of the first UE. The historical parameter configuration includes at least one of the following: measurement threshold, measurement period, etc. If the network search result reported by the first UE shows that when the first UE measures with measurement threshold A and measurement period B, the first UE selects a suitable cell to reside in, and the average number of cell reselection measurements is reduced, and the throughput is not reduced, the base station can adjust the measurement configuration information sent to the second UE according to the measurement threshold reported by the first UE, or the measurement period. For example, the base station shows that the measurement threshold configured by the base station is too high, or the measurement period is too small, according to the measurement threshold or measurement period reported by the first UE. The base station lowers the measurement threshold or increases the measurement period. Exemplarily, the base station may directly use the measurement start threshold or measurement period reported by the first UE. For example, the first measurement configuration information reported by each first UE is a set of measurement configuration parameters recommended by the first UE, and the measurement configuration parameters include the measurement start threshold, measurement interval, etc. The base station determines the measurement configuration parameters sent to the second UE based on the multiple sets of measurement configuration parameters reported by multiple first UEs. For example, the base station generates a set of measurement configuration parameters (i.e., second measurement configuration parameters) sent to the UE by integrating multiple sets of measurement configuration parameters. Exemplarily, the base station receives measurement start thresholds reported by multiple UEs, and the base station selects the measurement start threshold with the highest measurement start threshold from the measurement start thresholds reported by each first UE as the measurement start threshold in the second measurement configuration information; and / or, the base station selects the measurement interval with the smallest measurement interval from the measurement interval corresponding to each first UE as the measurement interval in the second measurement configuration information. It can be understood that there is no limitation on how the base station integrates multiple sets of configuration parameters to generate the second measurement configuration information.

[0265] For another example, the first measurement configuration information reported by each first UE includes N sets of measurement configuration parameters and the effectiveness conditions corresponding to the N sets of measurement configuration parameters. The base station integrates multiple sets of configuration parameters to generate the configuration parameter configuration sent to the second UE. What is sent to the second UE may be one set of measurement parameter configuration or M sets of measurement parameter configuration. Exemplarily, the base station selects M sets of measurement configuration parameters and the effectiveness conditions corresponding to the M sets of measurement configuration parameters from all the received measurement configuration parameters and the effectiveness conditions corresponding to the measurement configuration parameters to form the second measurement configuration information. It can be understood that the method for how the base station integrates multiple sets of configuration parameters to generate the second measurement configuration information is not limited.

[0266] In one possible manner, the second measurement configuration information includes a set of measurement configuration parameters, or includes M sets of measurement configuration parameters and effectiveness conditions corresponding to the M sets of measurement configuration parameters, where M is a positive integer and M may be greater than, equal to, or less than N.

[0267] Step 604: The base station sends second measurement configuration information.

[0268] The manner in which the base station sends the second measurement configuration information may refer to the description of the base station sending the measurement configuration information in step 403, and the "measurement configuration information" in step 403 may be replaced with "second measurement configuration information" for understanding.

[0269] Optionally, the base station may also broadcast a set of measurement configuration information (i.e., second measurement configuration information) in the cell managed by the base station based on the prior art. The second measurement configuration information is the same as the configuration information in the prior art, for example, only one set of configuration parameters, and optionally, no validity conditions are included. After receiving the configuration parameters, the UE directly applies the configuration parameters for measurement.

[0270] Correspondingly, the second UE receives second measurement configuration information from the base station.

[0271] The first UE is a UE that reports the first measurement configuration information, and the second UE is a UE that receives the second measurement configuration information. The first UE is one or more, and the second UE may also be one or more.

[0272] It should be pointed out that, for a certain UE, the UE can not only report the first measurement configuration information to the base station based on the historical measurement configuration parameters, but also receive new measurement configuration information (i.e., the second measurement configuration information) from the base station. At this time, the UE can choose to use the first measurement configuration information or the second measurement configuration information; or, the UE is only used to report the first measurement configuration information to the base station based on the historical measurement configuration parameters, or, the UE is only used to receive the second measurement configuration information from the base station.

[0273] Step 605: The second UE performs cell measurement according to the second measurement configuration information.

[0274] In one example, if the second measurement configuration information includes a set of measurement configuration parameters, the second UE can perform cell measurement according to the set of measurement configuration parameters. In another example, if the second measurement configuration information includes M sets of measurement configuration parameters and the effective conditions corresponding to the M sets of measurement configuration parameters, the second UE can determine its own state information, and then determine the measurement configuration parameters corresponding to the state information of the second UE according to the state information of the second UE, the M sets of measurement configuration parameters, and the effective conditions corresponding to the M sets of measurement configuration parameters. For specific implementation, refer to the description of the base station determining the measurement configuration parameters corresponding to the state information of the second UE in step 402. Further, the second UE performs cell measurement according to the measurement configuration parameters corresponding to the selected state information of the second UE.

[0275] For specific implementation of the second UE performing cell measurement (starting neighboring cell measurement, performing cell reselection, etc.) according to the measurement configuration information, refer to the description in step 404.

[0276] In the above technical solution, the first UE generates auxiliary information according to the historical measurement configuration parameters, and then generates the first measurement configuration information according to the auxiliary information. The first UE reports the first measurement configuration information to the base station, and accordingly, the base station can obtain the second measurement configuration information according to the first measurement configuration information, and the second measurement configuration information includes the measurement configuration parameters corresponding to the state information of the second UE. The second UE can perform cell measurement according to the measurement configuration parameters corresponding to the state information of the second UE, which helps to improve the efficiency of the second UE in performing cell measurement and reduce the power consumption of the second UE. Furthermore, the UE that cannot generate the first measurement configuration information according to the auxiliary information can also receive the second measurement configuration information from the base station, thereby improving the efficiency of cell measurement.
