Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a communication method, device, storage medium, and program product. Background Technology

[0002] The integration of Artificial Intelligence (AI) technology has brought revolutionary improvements to wireless networks, overcoming the limitations of traditional network management and opening new avenues for reducing operating costs and enhancing network performance. The 3rd Generation Partnership Project (3GPP) working group is exploring the deep integration of AI with the 5th Generation (5G) New Radio (NR) air interface and wireless network architecture. This integration aims to improve key capabilities such as spectrum efficiency, intelligent operation and maintenance, energy saving, and resource management, while ensuring data security. In 5G-Advanced, a specific area where AI / Machine Learning (ML) enhancements may occur is beam management, such as reducing overhead and latency and improving beam selection accuracy through temporal / spatial domain beam prediction.

[0003] Currently, the use cases for AI / ML models in beam management include: spatial downlink beam prediction of beam set A based on the measurement results of beam set Set B.

[0004] Regardless of whether the AI / ML model is deployed on the network side or the UE side, its performance monitoring phase suffers from problems such as high data transmission overhead or inaccurate model monitoring results due to inflexible resource and cycle configuration. Summary of the Invention

[0061] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0062] To facilitate understanding of the present invention, the relevant content involved in the present invention will be introduced first.

[0063] See Figure 1 For models deployed on the network (NW) side, during the training phase, the network can scan all potential beams, and the user equipment (UE) can use these beams to provide training input measurement results. After model training is complete, the network scans a small set of beams during the inference phase, and the UE feeds back the measurement results to the network. The network infers the IDs of the Top-K beams, then scans these reported candidate beams, and the UE determines the optimal beam ID and feeds it back to the network.

[0064] See Figure 2 For models deployed on the UE side, during the training phase, the network can scan all potential beams, and the UE can determine the best beam ID as the training label based on these beams. After the model training is completed, the network only needs to scan a small group of beams during the inference phase. The UE feeds back the IDs of the inferred Top-K beams to the network, and the network then scans these reported candidate beams. The UE determines the best beam ID and feeds it back to the network.

[0065] When performing performance monitoring, the relevant solutions configure monitoring reports and monitoring resources as follows:

[0066] 1) Enhance the CSI-ReportConfig sent by NW to UE, for example, indicate the monitoring resources in the resourcesForChannelMeasurement field, indicate the reporting period configuration in the reportConfigType field, and indicate the 'BAI-r19' field value in the reportQuantity field, which is used to notify UE to report performance monitoring indicators (such as beam prediction accuracy).

[0067] 2) Configure the period for sending reference signal resources in CSI-ResourceConfig, which is the monitoring resource configuration sent by NW to UE.

[0068] Due to time-varying channel conditions, the monitoring frequency required for model performance monitoring is also time-varying. However, in existing technologies, the model monitoring phase utilizes reference signals with fixed transmission periods and monitoring information reporting with fixed periods, resulting in inflexible resource and period configuration. This leads to the following problems:

[0069] 1. The monitoring phase used too many redundant resources, which increased unnecessary reporting overhead and unnecessary reference signal transmission overhead.

[0070] 2. Untimely adjustment of resource and cycle parameters leads to insufficient monitoring information, resulting in inaccurate monitoring results obtained by the model during the monitoring phase.

[0071] To address the aforementioned problems, this invention provides a communication method, device, storage medium, and program product. The method and device are based on the same concept, and since the principles by which they solve the problems are similar, implementations of the device and method can be mutually referenced; repeated details will not be elaborated further.

[0072] like Figure 3 As shown, this embodiment of the invention provides a communication method applied to a first communication device. Optionally, the first communication device is a terminal. Specifically, the method may include:

[0073] Step 301: Switch the current configuration information from the first configuration information to the second configuration information. The second configuration information is different from the first configuration information. Both the first configuration information and the second configuration information are used for information reporting.

[0074] Step 302: Send a first information report to the second communication device according to the second configuration information.

[0075] Optionally, the second communication device is a network device, such as a base station. It should be noted that the aforementioned information report can be an information report related to model performance monitoring.

[0076] Here, the first information report mentioned in this invention and the second information report mentioned below can both refer to information reports on channel measurement resources, such as channel state information (CSI) reports.

[0077] The communication method of this invention switches the current configuration information from first configuration information to second configuration information, where the second configuration information is different from the first configuration information. Both the first and second configuration information are used for information reporting. Then, based on the second configuration information, a first information report is sent to a second communication device. In this way, by dynamically adjusting the configuration of the information report, flexible configuration of model monitoring is achieved, thereby reducing data transmission overhead and improving the accuracy of model monitoring results.

[0078] In some embodiments, step 301 above may include:

[0079] Upon receiving a first switching instruction from the second communication device, the current configuration information is switched from the first configuration information to the second configuration information, wherein the first switching instruction instructs the first communication device to switch to the second configuration information; or,

[0080] When the first timer reaches the preset duration, the current configuration information will be switched from the first configuration information to the second configuration information.

[0081] Based on this, as an optional implementation, the method of this application also includes:

[0082] Receive third configuration information sent by the second communication device, the third configuration information including at least one configuration information;

[0083] When the first communication device performs a handover based on the first handover instruction, the second configuration information is one of the configuration information in the third configuration information; in this case, the first configuration information may be a default configuration indicated by the second communication device. That is, when the first communication device does not receive a handover instruction from the second communication device, it defaults to sending a second information report to the second communication device based on the first configuration information.

[0084] When the first communication device performs a handover based on the first timer, the first configuration information is one of the configuration information in the third configuration information. In this case, the second configuration information may be the default configuration indicated by the second communication device.

[0085] Based on this, as an optional implementation, the method of this application also includes:

[0086] Receive the first configuration information sent by the second communication device;

[0087] Based on the first configuration information, a second information report is sent to the second communication device.

[0088] It should be understood that, in this implementation, the first configuration information is the default configuration indicated by the second communication device, and the first communication device sends a second information report to the second communication device based on the first configuration information sent by the second communication device.

[0089] Optionally, the first configuration information includes: information reporting period, information reporting volume, and channel measurement resources;

[0090] Each configuration information in the third configuration information includes: information reporting period, information reporting quantity, and channel measurement resources;

[0091] Different configuration information corresponds to different information reporting periods, information reporting volumes, and / or channel measurement resources.

[0092] It should be understood that different configuration information corresponds to at least one of the following parameters: information reporting period, information reporting volume, and channel measurement resources.

[0093] In some embodiments, the method of this application further includes:

[0094] The device receives a Radio Resource Control (RRC) message sent by a second communication device. The RRC message includes first configuration information and third configuration information, wherein the third configuration information includes at least one configuration information and the first configuration information is the default configuration information.

[0095] For example, the terminal (i.e., the first communication device) receives a set of selectable CSI report configurations (i.e., the second configuration information) sent by the network device (i.e., the second communication device), as well as the default CSI report configuration (i.e., the first configuration information) configured by the network device.

[0096] Different report configurations may involve different reporting periods, different reporting volumes, or different channel measurement resources. Specifically:

[0097] The network device sends a set of CSI ReportConfigToAddModList to the terminal via RRC messages, which contains selectable CSI-ReportConfigIds and sets the default CSI-ReportConfigId.

[0098] Each CSI-ReportConfigId can be configured with:

[0099] Different reporting periods (reportSlotConfig), different reporting quantities (reportQuantity), or different channel measurement resources (resourcesForChannelMeasurement).

[0100] The following is an RRC message based on the ASN.1 format specification, in which initialReportConfig and ReportConfig-InactivityTimer are newly added information elements.

[0101]

[0102]

[0103] The meanings of the csi-ReportConfigToAddModList field are as follows:

[0104] Function: Used to add or modify the UE's CSI reporting configuration list.

[0105] content:

[0106] It contains one or more CSI-ReportConfig entries (SEQUENCE OF), each entry defining an independent set of CSI reporting configurations (such as reporting type, triggering conditions, measurement resources, etc.).

[0107] The list size is limited to 1..maxNrofCSI-ReportConfigurations (the maximum number of CSI reporting configurations defined by the protocol).

[0108] Optional:

[0109] OPTIONAL: This field is optional, but if it exists, it must contain at least one entry.

[0110] Need N: The network side (base station) needs to explicitly indicate whether this field is required.

[0111] The meanings of the csi-ReportConfigToReleaseModList field are as follows:

[0112] Function: Used to release (delete) the UE's current CSI reporting configuration.

[0113] content:

[0114] It contains one or more CSI-ReportConfigId (integer identifiers), each ID corresponding to a CSI reporting configuration to be released.

[0115] The list size is limited to 1..maxNrofCSI-ReportConfigurations.

[0116] Optional:

[0117] OPTIONAL: This field is optional, but if it exists, it must contain at least one ID.

[0118] Need N: The network side needs to explicitly indicate whether this field is required.

[0119] The meaning of the initialReportConfig field is as follows:

[0120] Purpose: Used to identify the default CSI reporting configuration.

[0121] Content: CSI-ReportConfigId (integer identifier).

[0122] Value range: 0..maxNrofCSI-ReportConfigurations-1, where maxNrofCSI-ReportConfigurations represents the maximum number of CSI reporting configurations defined by the protocol.

[0123] Optional:

[0124] OPTIONAL: This field is optional.

[0125] The meanings of the ReportConfig-InactivityTimer field are as follows:

[0126] Function: Used to control the waiting time for returning the default CSI reporting configuration.

[0127] Triggering condition: The UE sends a report according to the CSI reporting configuration after the handover and then starts.

[0128] Timeout behavior: After the timeout, the UE will report using the default CSI reporting configuration.

[0129] Optionally, the switching instruction used to indicate switching configuration information in this invention (which may be the first switching instruction mentioned above, and the second switching instruction mentioned below) is a Media Access Control Layer (MAC) control element (CE).

[0130] Specifically, the MAC CE reuses the semi-persistent channel state information SP CSI reporting on PUCCH Activation / Deactivation MAC CE based on the physical uplink control channel PUCCH, and the A / S field in the MAC CE is 1, and the Si field in the MAC CE indicates the activation or deactivation based on the periodic CSI reporting configuration.

[0131] It should be noted that the MAC CE used to indicate switching configuration information in this invention can reuse the SP CSI reporting on PUCCH Activation / Deactivation MAC CE. The information structure of the SP CSI reporting on PUCCH Activation / Deactivation MAC CE is described below. Figure 4 .

[0132] The A / S field indicates that the MAC CE is activated / deactivated based on the SP CSI report of PUCCH when the field is 0; and that the MAC CE is used to indicate the switching configuration information when the field is 1, i.e., the MAC CE is configured based on the periodic CSI report.

[0133] Serving Cell ID field: This field represents the serving cell identity used by MAC CE. This field is 5 bits long.

[0134] BWPID (Bandwidth Part Identifier): This field indicates the UL BWP (Uplink Bandwidth Part) applicable to MAC CE, corresponding to the code point in the Downlink Control Information (DCI) Bandwidth Part Indicator field. The BWP ID field is 2 bits long.

[0135] Si field: This field indicates the activation or deactivation status of the SP CSI report configuration (A / S set to 0) or the periodic CSI report configuration (A / S set to 1) in csi-ReportConfigToAddModList.

[0136] S0 represents a report configuration that includes the PUCCH resources used for CSI reports in the specified BWP and has the smallest CSI-ReportConfigId value in the list (where A / S is 0, the type is set to PUCCH-based semi-persistent; A / S is 1, the type is set to periodic); S1 represents a report configuration that includes the PUCCH resources used for CSI reports in the specified BWP and has the second smallest CSI-ReportConfigId value in the list, and so on.

[0137] If the number of reports configured in the specified BWP with type set to PUCCH-based semi-persistent (A / S set to 0) or periodic (A / S set to 1) is less than i+1, the MAC entity should ignore the Si field.

[0138] When the Si field is set to 1, it means that the corresponding SP CSI report configuration i (A / S set to 0) or the corresponding periodic CSI report configuration i (A / S set to 1) should be activated; when the Si field is set to 0, it means that the corresponding SP CSI report configuration i (A / S set to 0) or the corresponding periodic CSI report configuration i (A / S set to 1) should be deactivated.

[0139] R field: This field represents reserved bits, set to 0.

[0140] In some embodiments, after the first communication device receives a first handover instruction sent by the second communication device, and if it sends a PUCCH carrying HARQ-ACK in time slot n, the first handover instruction continues until time slot n. Effective, where μ is the subcarrier spacing configuration of PUCCH.

[0141] In other words, the first switching instruction (such as MAC CE configured based on periodic CSI reports) does not take effect immediately, but is subject to a certain delay.

[0142] Assuming that after the UE receives a PDCCH indicating handover configuration information (e.g., a MAC CE configured based on periodic CSI reports), and then sends a PUCCH carrying HARQ-ACK in time slot n, this MAC CE will continue until time slot n. Effective.

[0143] In some embodiments, the third configuration information further includes a preset duration of the first timer; correspondingly, the method of the present invention further includes:

[0144] When the first communication device performs a handover based on the first timer, the first timer is started at the same time as the second information report is sent to the second communication device for the first time with the first configuration information;

[0145] After the first timer reaches the preset duration, a first information report is sent to the second communication device according to the second configuration information.

[0146] Here, the third configuration information also includes the preset duration of the first timer, which means that in addition to including at least one configuration information, the third configuration information also includes the preset duration of the first timer.

[0147] It should be noted that when the first communication device sends the second information report to the second communication device for the first time using the first configuration information, it also starts a first timer (such as the ReportConfig-InactivityTimer newly added in the RRC message of the ASN.1 format specification). During the running time of the first timer, resource measurement reporting can be performed based on the first configuration information indicated by the switching instruction (such as CSI-ReportConfig). After the first timer expires (i.e., the corresponding duration is reached), the first communication device uses the second configuration information (i.e., the default configuration information, such as initialReportConfig) to perform CSI reporting.

[0148] This invention introduces a first timer. After the first timer expires, the system automatically reverts to the default reporting configuration. This avoids manual intervention or additional signaling triggers, ensuring monitoring accuracy in temporary high-demand scenarios while flexibly controlling resource usage time through timer parameters (configurable), preventing over-adjustment or resource leakage, and improving system robustness.

[0149] In some embodiments, the method of the present invention further includes:

[0150] If a second switching instruction is received from the second communication device during the operation of the first timer, the first timer is reset. The second switching instruction is used for the first communication device to switch to the fourth configuration information, which is one of the configuration information in the third configuration information.

[0151] In other words, if a MAC CE indicating CSI-ReportConfigId is received again during the operation of the first timer, the first timer is reset (that is, the first timer starts counting down again).

[0152] The following examples illustrate the specific implementation process of the communication method of the present invention.

[0153] Example 1

[0154] See Figure 5 The terminal receives an RRC message sent by the network device. The RRC message includes a selectable CSI-ReportConfigId (Id includes 1, 2, 3 and 4) and a default CSI-ReportConfigId (Id is 0).

[0155] Subsequently, the terminal receives a MAC CE sent by the network device, which indicates a switch to the reporting configuration with Id 2. Simultaneously with the terminal sending its first CSI report to the network device using the reporting configuration with Id 2, a timer is started. During the execution of this timer, the terminal receives another MAC CE sent by the network device, which indicates a switch to the reporting configuration with Id 3. Then, the timer is reset, and the timer is started again simultaneously with the terminal sending its first CSI report to the network device using the reporting configuration with Id 3. Finally, after the timer expires, the terminal sends a CSI report to the network device based on the default reporting configuration (i.e., the reporting configuration with Id 0).

[0156] This first embodiment, based on the RRC initial configuration (L3 layer) + MAC CE (L2 layer) + timer (L1 / L2 layer) mechanism, does not require changes to the physical layer reference signal structure. It achieves communication only through the coordination of upper-layer signaling and timer logic, and can be seamlessly integrated into the existing 5G / 6G protocol framework, significantly reducing standardization and deployment costs.

[0157] Example 2

[0158] See Figure 6 The implementation process of the communication method of the present invention will be described from the perspective of the interaction between the first communication device and the second communication device. In this embodiment, the terminal serves as the first communication device, and the base station serves as the second communication device.

[0159] Step 601: The terminal receives the CSI report configuration sent by the network device via RRC message;

[0160] Step 602: The terminal sends a PUCCH carrying a CSI report to the base station based on the configured first cycle;

[0161] Step 603: The terminal sends a PUCCH carrying a CSI report to the base station based on the configured first cycle;

[0162] That is, the terminal sends CSI reports to the base station twice in a row based on the first cycle (long cycle).

[0163] At this point, if the base station determines the model's performance monitoring indicators based on the two consecutive CSI reports received, such as the beam prediction accuracy being less than a preset threshold, the base station internally determines that a second cycle (short cycle) of rapid monitoring is required, and executes step 604.

[0164] Step 604: The base station sends a PDCCH carrying a MAC CE to the terminal. The MAC CE is used to switch the CSI report configuration.

[0165] Step 605: After receiving the MAC CE, the terminal sends a PUCCH carrying HARQ-ACK to the base station.

[0166] Step 606, MAC CE takes effect;

[0167] In other words, MAC CE does not take effect immediately, but rather there is a certain delay. After the terminal receives the PDCCH indicating the switching of the CSI report configuration MAC CE, if it sends a PUCCH carrying HARQ-ACK in time slot n, the MAC CE will not take effect until time slot n. Effective.

[0168] Step 607: When the terminal sends a PUCCH carrying a CSI report to the base station for the first time in the second cycle, the ReportConfig-InactivityTimer timer is started.

[0169] Step 608: The terminal sends a PUCCH carrying a CSI report to the base station in the second cycle;

[0170] Step 609: The terminal side determines that the ReportConfig-InactivityTimer timer has timed out;

[0171] Step 610: After the ReportConfig-InactivityTimer timer expires, the terminal sends a PUCCH carrying a CSI report to the base station in the first cycle.

[0172] In this second embodiment, when the channel is stable, a first cycle, i.e. a long cycle, is used for resource measurement and reporting, which can reduce overhead (reduce the frequency of reference signal transmission and terminal reporting load); when the channel changes drastically or the model monitoring requirements increase, a second cycle, i.e. a short cycle, is used for resource measurement and reporting (increase resource allocation to ensure monitoring accuracy). This can fundamentally solve the problem of fixed cycles.

[0173] Example 3

[0174] See Figure 7 The specific implementation process of the communication method of the present invention is described from a timeline. First, the terminal receives the CSI report configuration sent by the base station; then, the terminal sends the CSI report of the first resource to the base station in a first period (default); then, if the terminal receives a MAC CE sent by the base station indicating a switch of the CSI report configuration, the MAC CE takes effect after a certain delay; then, the terminal sends the CSI report of the second resource to the base station in accordance with the second period in the switched CSI report configuration; simultaneously, when the terminal first sends the CSI report of the second resource to the base station in the second period, a timer is started, and during the timer's operation, the terminal continuously sends the CSI report of the second resource to the base station in the second period; finally, after the timer expires, the terminal sends the CSI report of the first resource to the base station in the first period (default).

[0175] like Figure 8 As shown, this embodiment of the invention also provides a communication method, which is applied to a second communication device. Specifically, the method may include:

[0176] Step 801: Receive a first information report sent by the first communication device. The first information report is sent by the first communication device after switching the current configuration information from the first configuration information to the second configuration information, based on the second configuration information. The second configuration information is different from the first configuration information. Both the first configuration information and the second configuration information are used for information reporting.

[0177] Here, the method of this embodiment corresponds to the method on the first communication device side. For explanations of the relevant steps and terms, please refer to the description of the method on the first communication device side, which will not be repeated here.

[0178] In some embodiments, the method of this application further includes:

[0179] If the first preset condition is met, a first switching instruction is sent to the first communication device, the first switching instruction being used to instruct the first communication device to switch to the second configuration information.

[0180] The first preset condition may be a change in channel conditions or a change in monitoring requirements. When the channel conditions or monitoring requirements change, the second communication device sends a first switching command to the first communication device, instructing the first communication device to switch to the second configuration information.

[0181] Based on this, in some embodiments, the method of this application further includes:

[0182] Send third configuration information to the first communication device, the third configuration information including at least one configuration information;

[0183] When the first communication device performs a handover based on the first handover instruction, the second configuration information is one of the configuration information in the third configuration information; in this case, the first configuration information may be a default configuration indicated by the second communication device. That is, when the first communication device does not receive a handover instruction from the second communication device, it defaults to sending a second information report to the second communication device based on the first configuration information.

[0184] When the first communication device performs a handover based on a first timer, the first configuration information is one of the configuration information in the third configuration information. In this case, the second configuration information may be the default configuration indicated by the second communication device.

[0185] Based on this, as an optional implementation, the method of this application also includes:

[0186] Send the first configuration information to the first communication device;

[0187] Receive a second information report sent by the first communication device based on the first configuration information.

[0188] It should be understood that, in this implementation, the first configuration information is the default configuration indicated by the second communication device. The second communication device sends the first configuration information to the first communication device so that the first communication device sends a second information report to the second communication device based on the first configuration information sent by the second communication device. After that, the second communication device receives the second information report sent by the first communication device based on the first configuration information.

[0189] Optionally, the first configuration information includes: information reporting period, information reporting volume, and channel measurement resources;

[0190] Each configuration information in the third configuration information includes: information reporting period, information reporting quantity, and channel measurement resources;

[0191] Different configuration information corresponds to different information reporting periods, information reporting volumes, and / or channel measurement resources.

[0192] It should be understood that different configuration information corresponds to at least one of the following parameters: information reporting period, information reporting volume, and channel measurement resources.

[0193] In some embodiments, the method of this application further includes:

[0194] An RRC message is sent to the first communication device. The RRC message includes first configuration information and third configuration information, wherein the third configuration information includes at least one configuration information and the first configuration information is the default configuration information.

[0195] For example, the network device (second communication device) sends a set of selectable CSI report configurations (i.e., second configuration information) to the terminal (first communication device), as well as the configured default CSI report configuration (i.e., first configuration information).

[0196] Different report configurations may have different reporting periods, different reporting volumes, or different channel measurement resources.

[0197] Optionally, the switching instruction used to indicate switching configuration information in this invention (which may be the first switching instruction mentioned above, and the second switching instruction mentioned below) is a Media Access Control Layer (MAC) control element (CE).

[0198] Specifically, the MAC CE reuses the semi-persistent channel state information SP CSI reporting on PUCCH Activation / Deactivation MAC CE based on the physical uplink control channel PUCCH, and the A / S field in the MAC CE is 1, and the Si field in the MAC CE indicates the activation or deactivation of the periodic CSI reporting configuration.

[0199] Optionally, the third configuration information may also include the preset duration of the first timer.

[0200] In some embodiments, the method of the present invention further includes:

[0201] If the second preset condition is met, a second switching instruction is sent to the first communication device. The second switching instruction is used to instruct the first communication device to switch to the fourth configuration information, which is one of the configuration information in the third configuration information.

[0202] The second preset condition can be a change in channel conditions or a change in monitoring requirements. In other words, once the second communication device determines that the preset condition is met, it can send a switching command to the first communication device, instructing the first communication device to switch its configuration information and perform resource measurement and reporting according to the indicated configuration information.

[0203] The communication method of this invention receives a first information report sent by a first communication device. The first information report is sent by the first communication device after switching the current configuration information from the first configuration information to the second configuration information. The second configuration information is different from the first configuration information. Both the first configuration information and the second configuration information are used for information reporting. In this way, by dynamically adjusting the configuration of the information report, flexible configuration of model monitoring is realized, thereby reducing data transmission overhead and improving the accuracy of model monitoring results.

[0207] In some embodiments, the processor 900 is further configured to:

[0208] Upon receiving a first switching instruction from the second communication device, the current configuration information is switched from the first configuration information to the second configuration information, wherein the first switching instruction instructs the first communication device to switch to the second configuration information; or,

[0209] When the first timer reaches the preset duration, the current configuration information will be switched from the first configuration information to the second configuration information.

[0210] In some embodiments, transceiver 910 is further configured to:

[0211] Receive third configuration information sent by the second communication device, the third configuration information including at least one configuration information;

[0212] When the first communication device performs a handover based on the first handover instruction, the second configuration information is one of the configuration information in the third configuration information;

[0213] When the first communication device performs a handover based on the first timer, the first configuration information is one of the configuration information in the third configuration information.

[0214] In some embodiments, transceiver 910 is further configured to:

[0215] Receive the first configuration information sent by the second communication device;

[0216] Based on the first configuration information, a second information report is sent to the second communication device.

[0217] Optionally, the first configuration information includes: information reporting period, information reporting volume, and channel measurement resources;

[0218] Each configuration information in the third configuration information includes: information reporting period, information reporting quantity, and channel measurement resources;

[0219] Different configuration information corresponds to different information reporting periods, information reporting volumes, and / or channel measurement resources.

[0220] In some embodiments, the third configuration information further includes a preset duration of the first timer; correspondingly, the processor 900 is further configured to:

[0221] When the first communication device performs a handover based on the first timer, the first timer is started at the same time as the second information report is sent to the second communication device for the first time with the first configuration information;

[0222] After the first timer reaches the preset duration, a first information report is sent to the second communication device according to the second configuration information.

[0223] In some embodiments, the processor 900 is further configured to:

[0224] If a second switching instruction is received from the second communication device during the operation of the first timer, the first timer is reset. The second switching instruction is used for the first communication device to switch to the fourth configuration information, which is one of the configuration information in the third configuration information.

[0225] The first communication device in this embodiment of the invention switches the current configuration information from first configuration information to second configuration information, where the second configuration information is different from the first configuration information. Both the first and second configuration information are used for information reporting. Then, based on the second configuration information, a first information report is sent to the second communication device.
