Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a communication method, system, apparatus, device, and readable storage medium. Background Technology

[0002] In the same Channel State Information Reference Signals (CSI-RS) resource set, all CSI-RS resources are configured with the same measurement period. The terminal device measures the channel state according to the CSI-RS resources, generates the corresponding channel measurement results, and then reports the channel measurement results corresponding to multiple CSI-RS resources to the network device through the same CSI report. This reporting method is called aggregated reporting.

[0003] However, measuring the channel state of multiple CSI-RS resources in the same period not only increases the measurement and reporting overhead of the terminal equipment, but also requires the use of Radio Resource Control (RRC) signaling to reconfigure the period if the measurement period of the CSI-RS resources is to be changed, resulting in low communication efficiency. Summary of the Invention

[0004] This application provides a communication method, system, apparatus, device, and readable storage medium. When configuring CSI-RS resources from a network device to a terminal device, the solution adds an indication message to indicate the reporting method of the CSI report, wherein the reporting method includes individual reporting or aggregated reporting.

[0005] Firstly, a communication method is provided, which is applied to a terminal device, and the method includes: The system receives a first configuration message from a network device. This first configuration message is used to configure resources for the Channel State Information Reference Signal (CSI-RS). The first configuration message includes first indication information, which indicates the reporting method for the CSI report. Based on the first configuration message, the system measures the CSI-RS resources and generates a CSI report. The reporting method includes any one of the following: individual reporting, indicating a CSI report that includes a single CSI-RS resource; aggregated reporting, indicating a CSI report that includes multiple CSI-RS resources; both individual and aggregated reporting; and no reporting, indicating that no CSI report is reported.

The reporting method includes aggregated reporting, individual reporting, aggregated reporting and individual reporting, and no reporting. This enables the terminal device to use CSI-RS for measurement based on the indicated reporting method and generate a corresponding CSI report. This method is used to flexibly configure the reporting method of CSI reports and achieve different reporting methods without changing the reporting cycle of CSI-RS resources by using RRC reconfiguration, thereby reducing the data overhead and latency of the terminal device.

[0052] RAN1 is discussing whether to allow multiple CSI-RS resources with different periods to be configured for 48 / 64 / 128 ports in the same CSI-RS resource set. Each CSI-RS resource can perform channel state measurements for a maximum of 32 ports. Therefore, in large-scale port scenarios, the measurement results corresponding to multiple CSI-RS resources can be aggregated and reported as a single CSI report.

[0053] Typically, a CSI-RS resource measures the channel state of one panel. A panel can support one or more ports. Therefore, in multi-panel, large-scale port scenarios, network devices usually perform high-frequency, fine-grained tracking on the primary panel (generally the optimal panel), while only low-frequency updates are needed for other alternative panels. That is, for the primary panel, after the CSI-RS resource measures the channel state information corresponding to the primary panel, it reports it separately. For other alternative panels, after the CSI-RS resources corresponding to multiple alternative panels complete the channel state measurement, the CSI measurement results for each alternative panel are aggregated into a single CSI report for measurement. Therefore, forcing the same period not only places a heavy burden on the terminal equipment for measurement and reporting but also leads to frequent RRC reconfiguration due to the need to constantly adjust the measurement period of the CSI-RS resource, resulting in insufficient flexibility in RRC configuration. Therefore, from the perspective of reducing terminal equipment overhead, conforming to multi-panel usage patterns, and reducing signaling complexity, supporting different periods within the same resource set has significant advantages.

[0054] According to 3GPP TS 38.331 (Radio Resource Control Protocol) and TS 38.214 (Physical Layer Data Procedures), CSI configuration is hierarchical, mainly including the CSI resource configuration set (CSI-ResourceConfig), the non-zero power channel state information reference signal resource set (NZP-CSI-RS-ResourceSet), and the non-zero power channel state information reference signal resource (NZP-CSI-RS-Resource). The NZP-CSI-RS-ResourceSet contains three resource sets: periodic, semi-persistent, and aperiodic. The aperiodic resource set is transmitted only after being triggered by the Media Access Control Element (MAC CE); while the periodic resource set cannot be flexibly controlled by the MAC CE. If a period needs to be changed, reconfiguration via RRC signaling is required, making the switching process relatively complex.

[0055] Protocol TS 38.331 explicitly states that at the NZP-CSI-RS-Resource level, each resource is independently configured with its periodicityAndOffset parameter to define the period and slot offset of that CSI-RS resource. Typically, all CSI-RS resources within a resource set are configured with the same period. The reporting period is configured by the ReportingPeriodicity parameter in CSI-ReportConfig. The reporting period is bound to the CSI report configuration; one report configuration can be associated with multiple measurement resources, but the reporting period is independent of the measurement periods of these resources. That is, within a reporting period, for the same CSI-RS resource, there may be one or more measurement periods, meaning that the corresponding CSI report within that reporting period may include the measurement results of one or more CSI-RS.

[0056] Therefore, if CSI-RS resources with different measurement periods exist in the same resource set, without additional constraints, multiple CSI-RS resources participating in the same aggregation may have multiple measurement results based on different measurement times when the same CSI report configuration corresponds to a CSI resource set. This leads to inconsistent effective time references for the aggregation port, affecting aggregation gain. Furthermore, when the network device receives a CSI report, it is difficult to distinguish whether the current report is a fine-grained tracking report for a single resource (primary panel) or an aggregated report for multiple resources (multiple alternative panels), resulting in semantic ambiguity in the report. If multiple CSI report configurations are added to distinguish different modes, it will cause configuration bloat and management complexity.

[0057] Based on this, this application provides a communication method in which a network device sends configuration information of CSI-RS resources to a terminal device, carrying an indication information to indicate the reporting method of CSI reports. The reporting method includes any one of individual reporting, aggregated reporting, individual reporting and aggregated reporting, and no reporting. After the terminal device performs channel state measurement based on the CSI-RS resources, it reports the corresponding CSI report according to the corresponding reporting method. This allows the network device to distinguish the reporting type of CSI report after receiving it, reducing configuration difficulty and improving the flexibility of CSI report reporting, thereby improving communication efficiency.

[0058] One example, illustrative, please refer to Figure 2 It illustrates a flowchart of the communication method interaction provided in an exemplary embodiment of this application, such as... Figure 2 As shown, this embodiment may include the following steps S210 to S220.

[0059] S210, the network device sends the first configuration message to the terminal device.

[0060] The first configuration message is used to configure resources for CSI-RS. The first configuration message includes first indication information, which indicates the reporting method of CIS reports. The reporting method includes any one of the following: separate reporting, which indicates that the CSI report includes a single CSI-RS resource; aggregate reporting, which indicates that the CSI report includes multiple CSI-RS resources; separate reporting and aggregate reporting; and no reporting, which indicates that CSI reports are not reported.

[0061] S220, the terminal device measures the CSI-RS resources based on the first configuration message and generates a CSI report.

[0062] Indicatively, the first configuration message is sent via RRC signaling; that is, the network device sends RRC signaling to the terminal device as the first configuration message.

[0063] Indicatively, the first configuration message is used to configure resources for CSI-RS. The configuration includes: CSI-ResourceConfig, NZP-CSI-RS-ResourceSet, and NZP-CSI-RS-Resource (which may also include CSI Interference Measurement (CSI-IM) resources). At the NZP-CSI-RS-ResourceSet level, there are three resource sets: periodic resource set, semi-persistent resource set, and aperiodic resource set. At the NZP-CSI-RS-Resource level, each resource is configured independently with its periodicityAndOffset parameter to define the period and slot offset of the CSI-RS resource.

[0064] Optionally, the first configuration message is used to configure resources for a single CSI-RS, or the first configuration message is used to configure resources for multiple CSI-RS.

[0065] If the first configuration message is used to configure resources for multiple CSI-RS, the multiple CSI-RS correspond to different measurement periods, or there are at least two CSI-RS corresponding to the same measurement period, for example: the measurement period corresponding to CSI-RS resource 1 is 5 milliseconds (ms), and the measurement period corresponding to CSI-RS resource 2 is also 5 ms.

[0066] Indicatively, one or more CSI-RS configured in the first configuration message are configured for the same CSI report. That is, one or more CSI-RS are used to serve the same measurement target. For example, for channel measurement scenarios, all CSI-RS configured in the first configuration message support the same codebook type (such as Type I or Type II) and the same number of antenna ports (such as 48 ports, 64 ports, or 128 ports). For interference measurement scenarios, all CSI-RS configured in the first configuration message (in this case, CSI-IM) cover the same interference scenario.

[0067] Indicatively, the configuration of a CSI report includes: time-domain behavior (e.g., CSI reports are periodic, non-periodic, and semi-persistent), bandwidth, precoding matrix indicator (PMI), rank indicator (RI), channel quality indicator (CQI), and associated CSI resource set (including one or more CSI-RS).

[0068] Optionally, the reporting methods include the following: 1. Report separately If the reporting method is individual reporting, it means that the terminal device completes the measurement (e.g., channel measurement or interference measurement) based on a single CSI-RS, obtains the measurement result corresponding to that CSI-RS, and then sends the measurement result corresponding to the CSI-RS as a separate CSI report to the network device. In this case, the CSI report only includes the measurement result of one CSI-RS. Furthermore, in the individual reporting scenario, the reporting period of the individual CSI report is related to the measurement period of the CSI-RS, but not to the preset reporting period of the CSI report. For example, CSI-RS resource 1 supports individual reporting, and the corresponding measurement period is 5ms. Therefore, the reporting period of the CSI report corresponding to CSI-RS resource 1 is 5ms (it can also be 6ms, 7ms, etc., and is not limited to this). The preset reporting period of the CSI report is 20ms. It can be seen that the reporting period of the individual CSI report is unrelated to the preset reporting period of the CSI report.

[0069] 2. Aggregated reporting If the reporting method is aggregated reporting, it means that after the terminal device completes the measurement (e.g., channel measurement or interference measurement) based on a single CSI-RS and obtains the measurement result corresponding to that CSI-RS, it does not report it immediately. Instead, it waits until it obtains the measurement results corresponding to a preset number of CSI-RSs, and then sends these measurement results as a single CSI report to the network device. In this case, the CSI report only includes the measurement results of multiple CSI-RSs. The preset number is related to the CSI report reporting cycle; for example, the preset CSI report reporting cycle is 20ms. If the measurement period of CSI-RS resource 1 is 5ms and the measurement period of CSI-RS resource 2 is 20ms, then within one reporting period, there can be 4 measurement results corresponding to CSI-RS resource 1 (measured at 5ms, 10ms, 15ms and 20ms respectively) and 1 measurement result corresponding to CSI-RS resource 2 (measured at 20ms). Therefore, the CSI report can include the above 5 measurement results. It can be seen that in the aggregated reporting scenario, the reporting period of the CSI report using the aggregated reporting method is the preset reporting period.

[0070] Optionally, in the aggregated reporting scenario, within a preset reporting period corresponding to the CSI report, the CSI report includes the measurement results corresponding to all CSI-RS resources configured in the first configuration message; or, the CSI report includes the measurement results corresponding to some CSI-RS resources configured in the first configuration message, and the other part of the CSI-RS resources can be reported in the CSI report generated in the next reporting period.

[0071] 3. Aggregated reporting and individual reporting If the reporting method is aggregated reporting and individual reporting, it means that the terminal device completes the measurement (e.g., channel measurement or interference measurement) based on a single CSI-RS, obtains the measurement result corresponding to the CSI-RS, and then performs an individual report. After obtaining the measurement results corresponding to a preset number of CSI-RS, the measurement results corresponding to the multiple CSI-RS are sent to the network device as a CSI report. At this time, the aggregated CSI report includes the individually reported CSI report.

[0072] It is worth noting that, in this scenario, taking a separately reported CSI report as Report 1 corresponding to CSI-RS resource 1 and a collectively reported CSI report as Report 2 as an example, the content of the CSI-RS resource 1 report included in Report 2 may be the same as or different from the content of the report in Report 1. For example, if Report 2 includes PMI, CQI, and RI measured by CSI-RS resource 1, and Report 1 includes CQI and RI measured by CSI-RS resource 1, then the content of the CSI-RS resource 1 report included in Report 2 is different from the content of the report in Report 1. Conversely, if Report 2 includes CQI and RI measured by CSI-RS resource 1, and Report 1 includes CQI and RI measured by CSI-RS resource 1, then the content of the CSI-RS resource 1 report included in Report 2 is the same as the content of the report in Report 1. Typically, PMI can only be reported through aggregated reporting; therefore, the PMI measured by CSI-RS resource 1 is usually reported through aggregated reporting.

[0073] 4. Failure to report If the reporting method is "no reporting", it means that after the terminal device completes the measurement based on a single CSI-RS, it will not report the measurement result of that CSI-RS; or, it means that the terminal device does not use that CSI-RS for measurement, and therefore there is no corresponding CSI-RS measurement result.

[0074] In some implementations, after receiving the first configuration message, the terminal device performs measurements (including channel measurements or interference measurements) according to the configured CSI-RS and obtains the corresponding measurement results of the CSI-RS.

[0075] The following section explains how network devices determine whether to perform individual reporting and the process of CSI-RS involving individual and aggregated reporting.

[0076] In 5G New Ratio (NR) systems, the signal used to detect the uplink channel status from the terminal device to the network device is called the SRS (Sounding Reference Signal), and the signal used to detect the downlink channel from the network device to the terminal device is called the CSI-RS (Current Sequence Indicator Signal).

[0077] SRS refers to the uplink reference signal used for channel estimation or beam management. SRS measurement resources refer to the time-frequency resources configured by network devices for SRS, used for beam alignment between network devices and terminal devices. During beam alignment, terminal devices can send SRS to network devices on SRS measurement resources, while network devices can receive and measure the SRS sent by user equipment on SRS measurement resources.

[0078] Therefore, network devices configure SRS resources for terminal devices by sending configuration messages (e.g., RRC signaling), specifying parameters such as the SRS transmission period, port mapping relationship, and frequency domain location, ensuring that the SRS port is associated one-to-one with the multi-panel resources within the CSI resource set (each panel resource corresponds to one CSI-RS). The terminal device sends an SRS reference signal to the network device through a specified uplink port. This SRS reference signal carries the association identifier between its own port and the corresponding panel, ensuring that the network device can accurately identify the measurement object.

[0079] After receiving the SRS sent by the terminal device, the network device uses signal demodulation and channel estimation algorithms to obtain the uplink channel quality corresponding to each SRS port, and maps it to the potential downlink channel quality of the corresponding panel. The network device compares the SRS estimation results of all panels bound to resources, selects the panel with the best quality and its corresponding downlink port, and determines the reporting method of the CSI-RS corresponding to the best panel as either individual reporting or individual reporting and aggregate reporting. The reporting method of the CSI-RS corresponding to other panels is determined as aggregate reporting or no reporting.

[0080] Optionally, the configuration message used to configure SRS and the configuration message used to configure CSI-RS may be the same configuration message. For example, the first configuration message may be used for both SRS and CSI-RS resource configuration. Alternatively, the configuration message used to configure SRS and the configuration message used to configure CSI-RS may be different configuration messages. That is, before the network device sends the first configuration message to the terminal device, another configuration message (e.g., the fifth configuration message) may be sent for SRS resource configuration.

[0081] The following is a detailed explanation of the instructions for reporting methods.

[0082] In some embodiments, when the first indication information is a first value, the first value is used to indicate individual reporting; or, when the first indication information is a second value, the second value is used to indicate aggregated reporting; or, when the first indication information is a third value, the third value is used to indicate both individual reporting and aggregated reporting; or, when the first indication information is a fourth value, the third value is used to indicate no reporting.

[0083] Schematic, the first configuration message introduces a resource-level parameter defaultReportMode (usually represented by 2 bits) mapping table (i.e., the first indication information) to indicate the reporting mode within a preset time period (e.g., 1 minute). In one example, if defaultReportMode is 00 (i.e., the second value), it indicates that the reporting method is aggregated reporting (AggOnly); if defaultReportMode is 01 (i.e., the first value), it indicates that the reporting method is single reporting (SingleOnly); if defaultReportMode is 10 (i.e., the third value), it indicates that the reporting method is single reporting and aggregated reporting (Single+Agg); if defaultReportMode is 11 (i.e., the fourth value), it indicates that the reporting method is no reporting (Frozen).

[0084] Therefore, the mapping table includes four indication methods: 00, 01, 10, and 11.

[0085] In one implementation, when the first configuration message includes resource configurations for multiple CSI-RSs, each CSI-RS corresponds to a first indication message, which indicates the reporting method for each CSI-RS.

[0086] In one implementation, when the first configuration message includes resource configurations for multiple CSI-RSs, the first configuration message includes only one first indication message, which indicates that the multiple CSI-RSs configured in the first configuration message adopt the same reporting method.

[0087] In one implementation, when the first configuration message includes resource configurations for multiple CSI-RSs, each CSI-RS corresponds to a resource index. The first configuration message contains one or more first indication messages, and each first indication message is associated with one or more resource indexes. Therefore, the first indication message indicates that the CSI-RSs corresponding to the resource indexes associated with it all adopt the same reporting method indicated by the first indication message. For example, the first configuration message is used to configure resource 1, resource 2, and resource 3. Resource 1 corresponds to index 1, resource 2 corresponds to index 2, and resource 3 corresponds to index 3. Therefore, the first configuration message includes first indication information 1 and first indication information 2. First indication information 1 is associated with index 1, and first indication information 2 is associated with index 2 and index 3. First indication information 1 is 00, and first indication information 2 is 01. It can be seen that the reporting method corresponding to resource 1 is aggregate reporting, and the reporting methods corresponding to resource 2 and resource 3 are both individual reporting.

[0088] In some embodiments, the CSI-RS resource includes a first CSI-RS resource, which corresponds to a first CSI report; when the first indication information is a first value, the CSI report is the first CSI report, and the reporting period of the first CSI report is a first period; or, when the first indication information is a second value, the CSI-RS report includes at least one CSI report corresponding to a CSI-RS resource, wherein the CSI report includes the first CSI report, and the reporting period of the CSI report is a second period; or, when the first indication information is a third value, the CSI report includes both a first CSI report and a third CSI report, wherein the third CSI report includes at least one CSI report corresponding to a CSI-RS resource, the third CSI report includes the first CSI report, and the reporting period of the third CSI report is a second period; or, when the first indication information is a fourth value, the CSI report does not include the first CSI report; wherein the first period is the measurement period of the first CSI-RS resource, the second period is a preset reporting period of the CSI report, and the first period is shorter than the second period.

[0089] To illustrate, taking the CSI-RS resource in the first configuration message as the first CSI-RS resource as an example, the first period refers to the measurement period of the first CSI-RS resource, for example: 5ms, and the second period refers to the CSI report reporting period preset in the first configuration message, for example: 20ms.

[0090] In one implementation, if the first indication information is a first numerical value, it indicates that the reporting method of the first CSI-RS resource is separate reporting. In this case, the CSI report generated after the measurement of the first CSI-RS resource is the first CSI report corresponding to the first CSI-RS resource. That is, the first CSI report only includes the measurement results of the first CSI-RS resource. The reporting period of the first CSI report is a first period (e.g., 5ms), meaning that the first CSI report is reported immediately after the terminal device completes the measurement using the first CSI-RS resource.

[0091] In one implementation, if the first indication information is a second value, it indicates that the reporting method for the first CSI-RS resource is aggregated reporting. In this case, after the first CSI-RS resource is measured, the final generated CSI report includes the measurement results corresponding to multiple CSI-RS resources, including the first CSI report corresponding to the first CSI-RS resource. The reporting period for the CSI report is a pre-set second period. That is, after the terminal device completes the measurement using the first CSI-RS resource, until the end of the second period, the CSI report corresponding to the measurement results of the multiple CSI-RS resources measured within the second period is reported.

[0092] In one implementation, if the first indication information is a third value, it indicates that the reporting method for the first CSI-RS resource is individual reporting or aggregated reporting. In this case, the CSI report is implemented as a first CSI report and a third CSI report. After the first CSI-RS resource is measured, the first CSI report is generated and reported. At this time, the reporting period for the first CSI report is a first period. At the end of the second period, the third CSI report is generated. The third CSI report includes the CSI reports corresponding to the measurement results of multiple CSI-RS resources measured during the second period. At this time, the third CSI report includes the first CSI report, or the third CSI report includes the PMI measured by the first CSI-RS resource during the first period. In this case, the reporting period for the third CSI report is a pre-set second period, and the reporting period for the first CSI report is the first period.

[0093] In one implementation, if the first indication information is the fourth value, it indicates that the reporting method of the first CSI-RS resource is step reporting. At this time, at the end of the second cycle, the generated CSI report does not include the measurement results corresponding to the first CSI-RS resource, but may include the measurement results corresponding to multiple other CSI-RS resources. In this case, the reporting cycle of the CSI report is also the second cycle.

[0094] As can be seen from the above four examples, the first instruction information is used to change the reporting cycle of the CSI report corresponding to CSI-RS, but not the measurement cycle corresponding to CSI-RS.

[0095] The activation methods for semi-persistent CSI-RS and aperiodic CSI-RS will be explained in detail below.

[0096] In one example, please refer to Figure 3 It illustrates a flowchart of the communication method interaction provided in an exemplary embodiment of this application, such as... Figure 3 As shown, S220 is preceded by S230.

[0097] S230, the network device sends the first instruction message to the terminal device.

[0098] The first indication message is used to determine the activation status of the CSI-RS resource. The first indication message includes the second indication information corresponding to the first CSI-RS resource. The second indication information is used to indicate any one of the following: deactivation; activation and aggregated reporting; activation and separate reporting; separate reporting and aggregated reporting.

[0099] Indicatively, the first indication message is usually sent in the form of MAC CE, that is, the network device sends MAC CE to the terminal device as the first indication message.

[0100] For illustrative purposes, if the CSI-RS is a semi-persistent or non-periodic resource, the network device needs to issue a MACCE to indicate whether the resource is activated. If only the activation of the resource is indicated, the terminal device can use the activated CSI-RS to perform measurements and obtain the corresponding measurement results.

[0101] Optionally, taking the CSI-RS resource as the first CSI-RS resource as an example, the activation states include the following: 1. Activate and report separately If the activation status is "Active" and reported separately, it indicates that the first CSI-RS resource is activated. The terminal device can use the first CSI-RS resource to perform measurements. After completing the measurement (e.g., channel measurement or interference measurement) based on the first CSI-RS and obtaining the measurement result corresponding to the CSI-RS, the terminal device sends the measurement result corresponding to the CSI-RS as a separate CSI report to the network device. At this time, the CSI report only includes the measurement result of the first CSI-RS. In the separate reporting scenario, the reporting period of the separately reported CSI report is related to the measurement period of the CSI-RS, but not to the preset reporting period of the CSI report. For example, CSI-RS resource 1 supports separate reporting, and the corresponding measurement period is 5ms. Therefore, the reporting period of the CSI report corresponding to CSI-RS resource 1 is 5ms (it can also be 6ms, 7ms, etc., and is not limited to this). The preset reporting period of the CSI report is 20ms. It can be seen that the reporting period of the separately reported CSI report is not related to the preset reporting period of the CSI report.

[0102] 2. Activate and aggregate reports If the activation status is "Active" and aggregated reporting is enabled, it indicates that the first CSI-RS resource is activated. The terminal device can utilize the first CSI-RS resource for measurement. After completing the measurement (e.g., channel measurement or interference measurement) based on a single CSI-RS and obtaining the measurement result corresponding to that CSI-RS, the terminal device does not report it immediately. Instead, it waits until it obtains the measurement results corresponding to a preset number of CSI-RSs, and then sends the measurement results corresponding to the multiple CSI-RSs as a single CSI report to the network device. At this point, the CSI report only includes the measurement results of the multiple CSI-RSs. The preset number corresponds to the CSI report reporting cycle. For example, if the preset reporting period for a CSI report is 20ms, the measurement period for CSI-RS resource 1 is 5ms, and the measurement period for CSI-RS resource 2 is 20ms, then within one reporting period, there can be 4 measurement results corresponding to CSI-RS resource 1 (measured at 5ms, 10ms, 15ms, and 20ms respectively) and 1 measurement result corresponding to CSI-RS resource 2 (measured at 20ms). Therefore, the CSI report can include the above 5 measurement results. It can be seen that in the aggregated reporting scenario, the reporting period of the CSI report using the aggregated reporting method is the preset reporting period.

[0103] Optionally, in the aggregated reporting scenario, within a preset reporting period corresponding to the CSI report, the CSI report includes the measurement results corresponding to all CSI-RS resources configured in the first configuration message; or, the CSI report includes the measurement results corresponding to some CSI-RS resources configured in the first configuration message, and the other part of the CSI-RS resources can be reported in the CSI report generated in the next reporting period.

[0104] 3. Activation and aggregated reporting as well as individual reporting. If the activation status is active and both aggregated and individual reporting are performed, it indicates that the first CSI-RS resource is activated. The terminal device can use the first CSI-RS resource to perform measurements. This means that the terminal device completes the measurement (e.g., channel measurement or interference measurement) based on a single CSI-RS. After obtaining the measurement result corresponding to the CSI-RS, it performs an individual report. After obtaining the measurement results corresponding to a preset number of CSI-RS, the measurement results corresponding to the multiple CSI-RS are sent to the network device as a CSI report. At this time, the aggregated CSI report includes the individually reported CSI report.

[0105] It is worth noting that, in this scenario, taking a separately reported CSI report as Report 1 corresponding to CSI-RS resource 1 and a collectively reported CSI report as Report 2 as an example, the content of the CSI-RS resource 1 report included in Report 2 may be the same as or different from the content of the report in Report 1. For example, if Report 2 includes PMI, CQI, and RI measured by CSI-RS resource 1, and Report 1 includes CQI and RI measured by CSI-RS resource 1, then the content of the CSI-RS resource 1 report included in Report 2 is different from the content of the report in Report 1. Conversely, if Report 2 includes CQI and RI measured by CSI-RS resource 1, and Report 1 includes CQI and RI measured by CSI-RS resource 1, then the content of the CSI-RS resource 1 report included in Report 2 is the same as the content of the report in Report 1. Typically, PMI can only be reported through aggregated reporting; therefore, the PMI measured by CSI-RS resource 1 is usually reported through aggregated reporting.

[0106] 4. Deactivate If the activation status is deactivated, it means that the terminal device cannot complete the measurement using the first CSI-RS.

[0107] In some embodiments, when the second indication information is a first value, the first value is used to indicate that the first CIS-RS resource is activated and reported separately; or, when the second indication information is a second value, the second value is used to indicate that the first CIS-RS resource is activated and reported aggregatedly; or, when the second indication information is a third value, the third value is used to indicate that the first CIS-RS resource performs separate reporting and aggregated reporting; or, when the second indication information is a fourth value, the fourth value is used to indicate that the first CIS-RS resource is not activated.

[0108] MAC CE (i.e., the first indication message) introduces a new parameter, ResourceBitmap (i.e., the second indication information, where each 2 bits correspond to a set of resource-level parameters, defaultReportMode): a bitmap, each bit containing 2 bits, with a maximum of 3. Each bit sequentially corresponds to a CSI-RS resource within the resource set. When the second indication information is set to '00' (i.e., the first value), it indicates that the activation state is deactivated; when the second indication information is set to '01' (i.e., the second value), it indicates that the activation state is active and only aggregated reporting is performed; when the second indication information is set to '10' (i.e., the third value), it indicates that the activation state is active and only reported individually; when the second indication information is set to '11', it indicates that the activation state is active and both individual and aggregated reporting are performed. The purpose is to allow network devices to selectively activate a specific resource within a resource set when activating the resource set via MAC CE, ensuring correct activation. For example: activating resources 1 and 3, where resource 1 can be reported individually: ResourceBitmap: 11 0001 ... Therefore, the mapping table includes four indication methods: 00, 01, 10, and 11.

[0109] In one implementation, when the second configuration message includes the activation status configuration of multiple CSI-RS, each CSI-RS has a corresponding second indication information to indicate the activation status of each CSI-RS.

[0110] In one implementation, if the second configuration message includes the activation status configurations of multiple CSI-RS, the first configuration message includes only one second indication message, which indicates that the multiple CSI-RS configured in the first configuration message adopt the same activation status and reporting method.

[0111] In one implementation, when the second configuration message includes the activation status configuration of multiple CSI-RS, each CSI-RS corresponds to a resource index. The second configuration message contains one or more second indication information, and each first indication information is associated with one or more resource indexes. Therefore, the first indication message indicates that the CSI-RS corresponding to its associated resource index all adopt the same activation status and reporting method indicated by the second indication information. For example, the second configuration message is used to configure the activation status of resource 1, resource 2, and resource 3. Resource 1 corresponds to index 1, resource 2 corresponds to index 2, and resource 3 corresponds to index 3. Therefore, the second configuration message includes second indication information 1 and second indication information 2. Second indication information 1 is associated with index 1, and second indication information 2 is associated with index 2 and index 3. Second indication information 1 is 00, and second indication information 2 is 01. It can be seen that the activation status and reporting method corresponding to resource 1 is active and aggregated reporting, while the activation status and reporting method corresponding to resource 2 and resource 3 are both active and reported individually.

[0112] In some embodiments, the first indication message further includes third indication information, which is used to indicate the measurement time window of the CSI-RS resource; the measurement time window includes the following: a first time window, which corresponds to a third period; a second time window, which corresponds to a fourth period, and the fourth period is greater than or equal to the third period.

[0113] When the same CSI resource set corresponds to the same CSI report configuration, the CSI resource set can simultaneously support "independent reporting of a single resource" and "aggregated reporting of all resources," with the corresponding activation status subsequently determined using MAC CE. When a CSI resource is configured for independent reporting, the reporting period for that CSI resource is shortened according to the actual measurement period of that resource. For example, if resource A has defaultReportMode=10 and a measurement period of 5ms, while the default reporting period for the resource set is 20ms, then resource A's reporting period will be 5ms when reported independently, but aggregate reporting will still be triggered at 20ms. A time window configuration table is added to the configuration parameters of the default reporting period bound to the resource set to accommodate aggregate reporting, as shown in Table 1. Four "one-time time window combinations" are predefined, as detailed in Table 1 below.

[0114] Table 1

[0115] As shown in Table 1, each combination corresponds to an indicator (i.e., the third indicator message), causing the MAC CE to select one of the indicators to activate CSI-RS (usually a 2-bit indicator). Let winprofileId (indicator) ∈ {0,1,2,3}, where, if using a 2-bit indicator, 00 corresponds to indicator "0", 01 corresponds to indicator "1", 10 corresponds to indicator "2", and 11 corresponds to indicator "3". Each combination contains three parameters: ΔT_strict: represents the strict consistency window, in units of CSI reporting cycles or the number of time slots corresponding to CSI; ΔT_loose: represents the upper limit of the soft mismatch window (ΔT_strict≤ΔT_loose); β_soft: represents the weight of CSI resources participating in aggregation within the soft window (0<β_soft<1); and Δt: represents the time difference between the measurement time and the reporting time of the CSI resource.

[0116] In some embodiments, the CSI-RS resource corresponds to a single reporting period; when the third indication information is a fifth value, the fifth value is used to indicate that the third period is a single reporting period and the fourth period is a single reporting period; or, when the third indication information is a sixth value, the sixth value is used to indicate that the third period is a single reporting period and the fourth period is two reporting periods; or, when the third indication information is a seventh value, the seventh value is used to indicate that the third period is two reporting periods and the fourth period is four reporting periods; or, when the third indication information is an eighth value, the eighth value is used to indicate that the third period is n reporting periods and the fourth period is m reporting periods, where m > 4, n > 4, and m and n are integers.

[0117] To illustrate, the first time window is set as a strict consistency window, the second time window is set as a soft mismatch window, the first time window corresponds to the third period, and the second time window corresponds to the fourth period.

[0118] For the first scenario in Table 1, the third and fourth cycles are both CSI cycles. In this case, the CSI report is an aggregated CSI report. The measurement time of the CSI resource is within the preset reporting cycle corresponding to the CSI report. If the preset reporting cycle is 20ms, then the measurement results in the CSI report are all CSI measurement results obtained within 20ms.

[0119] In the second scenario in Table 1, the third period is one CSI period and the fourth period is two CSI periods. In this case, the CSI report is an aggregated CSI report. The measurement time of the CSI resource is within one preset reporting period corresponding to the CSI report, or within two preset reporting periods corresponding to the CSI report. If one preset reporting period is 20ms, the measurement result in the CSI report is the CSI measurement result obtained within 20ms. If there are measurement results before or after the current preset previous period, they can also be used as the measurement results in this CSI report. Therefore, there is a certain lag.

[0120] For the fourth scenario in Table 1, the third period is two CSI periods and the fourth period is four CSI periods. In this case, the CSI report is an aggregated CSI report. The measurement results of the CSI report are the CSI measurement results obtained within at least two preset reporting periods and at most four preset reporting periods. In this case, the lag is greater than that in the second scenario.

[0121] For the fourth scenario in Table 1, the third period is at least four CSI periods, and the fourth period is at least four CSI periods. In this case, the CSI report is an aggregated CSI report, and the measurement results in the CSI report are the measurement results corresponding to multiple preset reporting periods.

[0122] As an example, add a small field to the MAC CE: winProfileselect (third indication information): 2 bits, with values ​​0 / 1 / 2 / 3, corresponding to the 4 combinations in Table 1. Whenever a MAC CE with winProfileselect is received, update the CurwinProfileId (current status) to this value. This configuration remains in effect until the next MAC CE is received and adjusted accordingly.

[0123] In some embodiments, when the third indication information is a fifth value, the weight value corresponding to the fifth value is 0; or, when the third indication information is a sixth value, the weight value corresponding to the sixth value is a preset weight value; or, when the third indication information is a seventh value, the weight value corresponding to the seventh value is a preset weight value; or, when the third indication information is an eighth value, the weight value corresponding to the eighth value is 1.

[0124] In some embodiments, the first indication information is used to indicate that the reporting method corresponding to multiple CSI-RS resources is aggregated reporting. The multiple CSI-RS resources include a second CSI-RS resource. The second CSI-RS resource measures at a first time and generates a fourth CSI report at a second time. The first time and the second time correspond to a first time difference. The weight value corresponding to the second CSI-RS resource is determined based on the first time difference, the first time window, and the second time window. The CSI report is obtained by weighting and combining the measurement results and weight values ​​corresponding to the multiple CSI-RS resources respectively.

[0125] During aggregated reporting, at the reporting time of a specific CSI resource set: The first step is for the terminal device to read the currently effective curwinProfileId (current status): if the MAC CE has issued winProfileselect, use the latest value; otherwise, leave it unchanged.

[0126] The second step is to retrieve the following values ​​from Table 1 based on curwinprofilerd: ΔT_strict, ΔT_loose, β_soft The third step is to determine the resource set S participating in the aggregation based on ResourceBitmap / defaultReportmode. The fourth step is to assign an aggregation weight w_i to each resource based on (ΔT_strict, ΔT_loose, β_soft) in the current combination. For example, the second CSI-RS resource is measured at the first time and generates the fourth CSI report at the second time. The difference between the first time and the second time corresponds to the first time difference, which is represented by Δt_i.

[0127] 1. If Δt_i ≤ ΔT_strict, it means w_i = 1 (strict consistency window), and the weight value is 1. 2. If ΔT_strict < Δt_i ≤ ΔT_loose, it means w_i = β_soft (soft mismatch compensation window). In this case, the weight value is β_soft. Based on the third indication information in MAC CE, the corresponding combination in Table 1 selected by MAC CE is determined, and the β_soft corresponding to the combination is used as the weight value of the second CSI-RS resource.

[0128] 3. Δt_i>ΔT_loose means w_i=0 (the time is too old, and the resource is discarded in this aggregation). At this time, the weight value is 0.

[0129] 4. Perform weighted calculations based on the measured CSI and w_i: aggregate PMI, CQI, CRI, RI, and other required aggregate amounts.

[0130] 5. Construct a ReportBitmap to represent the usage status of each resource in this aggregation. For example, when the bit is set to: '00': indicates that the resource was not measured (w_i=0 or not measured); '01': used within a strict window (w_i=1); '10': used within a soft window (w_i=β_soft). Inform the base station whether the measurement results of CSI1 (short cycle) have been weighted.

[0131] The fifth step is to weight and calculate the measurement results of each CSI resource, aggregate them together, and report them to the terminal device. In some embodiments, if the first time difference is less than or equal to the first time window, the weight value is determined to be 1; or if the first time difference is greater than the first time window and less than the second time window, the weight value is determined to be a preset weight value; or if the first time difference is greater than the second time window, the weight value is determined to be 0.

[0132] In one example, such as Figure 4 As shown, it illustrates a flowchart of the communication method interaction provided in an exemplary embodiment of this application, as follows: Figure 4 As shown, the embodiment also includes S240.

[0133] S240, the network device sends a second instruction message to the terminal device.

[0134] The second indication message is used to indicate the measurement cycle of the first CSI-RS resource; the second indication message includes third indication information. The second indication message includes a preset number of bits: When the bit is the first value, the bit is used to indicate the measurement of the first CSI-RS resource in the first period; When the bit is the second value, the bit is used to indicate that the measurement of the first CSI-RS resource should be stopped within the first cycle.

[0135] Indicatively, a new parameter, Skip_Time (i.e., the second indication message), is introduced, consisting of six bits (or four bits, the specific number is not limited). This parameter is used to skip the current measurement of a (short-period) CSI resource, thereby enabling flexible scheduling of the CSI resource reception period from the perspective of the terminal device, achieving the purpose of changing the CSI resource measurement period. For example, if a resource is measured with a period of 5ms, setting Skip_Time to '101010' means stopping the measurement after each measurement, where the first value is 1 and the second value is 0. This changes the period of the resource to 10ms. Some resources initially have short periods, but later, when they become less important, they can be adjusted to longer periods using skip time.

[0136] Similarly, if Skip_Time is set to '100100', meaning the measurement is stopped twice after each measurement, the resource's period becomes 15ms.

[0137] Network devices send third-party instruction information to terminal devices at fixed intervals to promptly adjust the measurement time of certain resources. (If no adjustment is needed, the default value is Skip_Time='111111').

[0138] This is illustrative; please refer to it. Figure 5 It illustrates a schematic diagram of the communication method interaction process provided in an exemplary embodiment of this application, such as... Figure 5 As shown, the method includes the following steps.

[0139] S501, the network device sends an RRC pre-configuration message to the terminal device.

[0140] S502, the terminal device sends the SRS measurement results to the network device.

[0141] S503, network devices perform port quality measurements.

[0142] S504: The network device activates the time window corresponding to the terminal device at the MAC layer and sends skiptime to the terminal device.

[0143] S505: The terminal device performs CSI measurements and reports the CSI data to the network device.

[0144] The CSI report can be submitted in several ways, including individual submission, aggregated submission, individual submission and aggregated submission, and no submission.

[0145] S506, network devices adjust resource measurements based on CSI report feedback.

[0146] As an illustration, after the network device receives the report from the terminal device: 1. Directly use the aggregated PMI / CQI provided by the terminal device for precoding and scheduling; 2. Determine the consistency of the aggregation using ReportBitmap: If most critical resources are in the strict window (01), it means that the currently selected WinProfile is well adapted; If a large amount of resources are soft windows (10) or unused (00), it indicates that there is a significant time mismatch. You can adjust the currently active WinProfile or adjust ResourceBitmap and Skip_Time in MAC CE (to guide the retransmission every 6 short cycles).

[0147] 3. In the long term, based on the trends reported by SRS + CSI, gNB determines which panel / resource enters a short cycle and which reverts to a long cycle, and updates the measurement strategy of the terminal device through ResourceBitmap and Skip_Time.
