[0033] Next, in conjunction with the accompanying drawings, the technical solutions provided in the embodiments of the present application will be described in detail through some embodiments and their application scenarios.
[0034] As Figure 2 shown, it is a schematic flowchart of a method 200 for reporting channel state information provided by an exemplary embodiment of the present application. The method 200 can be, but is not limited to, executed by a terminal, and can be specifically executed by at least one of the hardware and software installed in the terminal. In this embodiment, the method 200 can at least include the following steps.
[0035] S210, the terminal obtains target configuration information.
[0036] Among them, the first indication information is carried or associated in the target configuration information, and the first indication information is used to explicitly or implicitly indicate that the terminal needs to report the beam prediction result. Based on this, for the LTM enhancement scenario with AI or ML assistance introduced, in the present application, it can be determined whether the terminal needs to report the beam prediction result according to the target configuration information. For example, when the first indication information is carried in the target configuration information, it can be determined that the terminal needs to report the beam prediction result; otherwise, the beam prediction result does not need to be reported.
[0037] It can be understood that the beam prediction result is determined based on a beam prediction model. For example, the historical measurement data of the predicted cell can be used as the input of the beam prediction model to predict the beam prediction result corresponding to the predicted cell. Alternatively, the beam measurement result currently actually measured in the measurement cell can be used as the input of the beam prediction model to predict the beam prediction result of the measurement cell, which is not limited herein. Among them, the beam prediction model is trained based on an AI model or an ML model. Herein, the predicted cell mentioned in the context of this application can be understood as a cell for which beam quality prediction is required, such as a serving cell, a neighboring cell, an LTM candidate cell, etc. The measurement cell can be understood as a cell for which beam quality measurement is required, such as a serving cell, a neighboring cell, an LTM candidate cell, etc. In addition, the predicted cell and the measurement cell can be the same or different. For example, when the predicted cell and the measurement cell are the same, it can be determined that the terminal needs to perform beam quality measurement and beam quality prediction based on the predicted cell.
[0038] In this case, as an optional implementation manner, the target configuration information can reuse the configuration information in related technologies and introduce the first indication information therein, or it can be newly introduced configuration information, which is not limited in this embodiment.
[0039] In addition, there can be multiple ways for the terminal to obtain the target configuration information. For example, the terminal can obtain the target configuration information from the network-side device, or it can obtain the target configuration information through protocol agreement or predefined manner, which is not limited herein.
[0040] It should be noted that the AI model mentioned in the context of this application can also be referred to as an AI unit, an ML model, an ML unit, an AI structure, an AI function, an AI feature, a neural network, a neural network function, a neural network capability, etc. Alternatively, the AI model can also refer to a processing unit capable of implementing specific algorithms, formulas, processing flows, capabilities, etc. related to AI. Or the AI model can also be a processing method, algorithm, function, module, or unit for a specific data set. Or the AI model can also be a processing method, algorithm, function, module, or unit running on AI / ML-related hardware such as a Graphics Processing Unit (GPU), a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), an Application Specific Integrated Circuit (ASIC), etc. This application does not make specific limitations in this regard. Optionally, the specific data set includes at least one of the input and output of the AI unit / AI model.
[0041] Optionally, the AI model identifier can be the identifier of the ML model, the AI structure identifier, the AI algorithm identifier, or the identifier of the specific data set associated with the AI unit / AI model, or the identifier of a specific scenario, environment, channel characteristic, or device related to AI / ML, or the identifier of a function, feature, capability, or module related to AI / ML. This application does not make specific limitations in this regard.
[0042] The AI functionality can be understood as an AI algorithm function, and the AI functionality may include multiple AI models.
[0043] S220. The terminal sends a first Channel State Information (CSI) report according to the first indication information.
[0044] Among them, the reporting of the first CSI report can also be understood as the reporting of layer 1 measurement results and layer 1 prediction results of the serving cell, neighboring cell, or LTM candidate cell, which can be used by the network-side device for channel quality assessment, cell handover, etc. The layer 1 prediction results may include, but are not limited to, beam prediction results.
[0045] The terminal sending the first CSI report according to the first indication information can be understood as: the terminal determines to add the beam prediction result obtained by reasoning based on the beam prediction model to the first CSI report according to the first indication information, so as to realize the reporting of the beam prediction result of the serving cell or neighboring cell after introducing the AI- or ML-assisted LTM enhancement.
[0046] Of course, in a possible implementation manner, the first CSI report may further include the beam measurement result obtained by actual measurement, etc.
[0047] Based on this, in this embodiment, a single reporting instance may include only the beam prediction result, or may include both the beam prediction result and the beam measurement result, which is not limited herein.
[0048] In this embodiment, the terminal obtains the target configuration information carrying the first indication information, and sends the first CSI report according to the first indication information, where the first indication information is used to instruct the terminal to report the beam prediction result, and the first CSI report includes the beam prediction result obtained by reasoning based on the beam prediction model. Thus, after introducing the AI- or ML-assisted LTM enhancement, the reporting of the beam prediction result of the serving cell or neighboring cell can be realized.
[0049] As Figure 3 shown, it is a schematic flowchart of a channel state information reporting method 300 provided by an exemplary embodiment of the present application. The method 300 may but is not limited to be executed by a terminal, and may specifically be executed by at least one of the hardware and software installed in the terminal. In this embodiment, the method 300 may at least include the following steps.
[0050] S310, the terminal obtains the target configuration information.
[0051] Wherein, the target configuration information carries the first indication information, and the first indication information is used to instruct the terminal to report the beam prediction result.
[0052] S320, the terminal sends the first CSI report according to the first indication information.
[0053] Wherein, the first CSI report includes the beam prediction result obtained by reasoning based on the beam prediction model.
[0054] It can be understood that the implementation process of S310 - S320 can refer to the relevant descriptions in the foregoing method embodiment 200. Of course, in addition to referring to the foregoing method embodiment 200, as a possible implementation manner, the target configuration information may include at least one of LTM CSI resource configuration (LTM - CSI - ResourceConfig), first LTM CSI reporting configuration (LTM - CSI - ReportConfig), and second LTM CSI reporting configuration.
[0055] Among them, the LTM CSI resource configuration is used to configure the relevant resources for layer 1 CSI measurement of the serving cell or neighboring cell, and it can be associated with the reference signal configuration (RS Config). In the embodiments of the present application, the LTM CSI resource configuration can also be associated with the first indication information, or the first indication information is carried in the LTM CSI resource configuration, so that the terminal can determine whether to carry the beam prediction result in the LTM CSI report corresponding to the LTM CSI reporting configuration associated with the LTM CSI resource according to whether the LTM CSI resource configuration carries or is associated with the first indication information.
[0056] It should be noted that if the target configuration information is the LTM CSI resource configuration, it means that the beam prediction result needs to be reported in all CSI reports associated with the LTM CSI resource configuration. In other words, when the target configuration information is the CSI resource configuration and the CSI resource configuration is associated with the CSI reporting configuration corresponding to the first CSI report, the terminal determines that the beam prediction result is carried in the first CSI report.
[0057] The first LTM CSI reporting configuration is used for the terminal to report the layer 1 measurement results of the serving cell or neighboring cell. For example, the reporting resources and relevant configurations of the reporting content are configured on the first LTM CSI reporting configuration, and it can be associated with the LTM CSI resource configuration. In the embodiments of the present application, the LTM CSI reporting configuration can also be associated with the first indication information, or the first indication information is carried in the LTM CSI reporting configuration, so that the terminal can determine whether to carry the beam prediction result in the LTM CSI report associated with the first LTM CSI reporting configuration according to whether the first LTM CSI reporting configuration carries or is associated with the first indication information.
[0058] It should be noted that if the target configuration information is the first LTM CSI reporting configuration, it means that the beam prediction result needs to be reported in all CSI reports associated with the first LTM CSI reporting configuration. In other words, when the target configuration information is the first LTM CSI reporting configuration and the first LTM CSI reporting configuration is associated with the first CSI report, the terminal determines that the beam prediction result is carried in the first CSI report.
[0059] Based on this, in an alternative implementation, for the target configuration information being the LTM CSI resource configuration and the first LTM CSI reporting configuration, there can be various implementation manners for the first indication information carried therein. For example, the first indication information can be newly introduced information used to explicitly indicate that the terminal reports the beam prediction result; or other information can be reused to implicitly indicate that the terminal reports the beam prediction result. For example, the model ID (model identifier) or functionality ID (functionality identifier) of the beam prediction model can be reused. When the LTM CSI resource configuration and the first LTM CSI reporting configuration include the model ID or functionality ID of the beam prediction model, it can be determined that the terminal needs to report the beam prediction result.
[0060] It should be noted that when the first indication information reuses the model ID or functionality ID of the beam prediction model, the model ID or functionality ID of the beam prediction model is simultaneously used to indicate that the beam prediction result to be reported by the terminal is determined based on the beam prediction model corresponding to the model ID or functionality ID.
[0061] Of course, for the case where the first indication information explicitly indicates that the terminal reports the beam prediction result, that is, the first indication information is other information except the model ID or functionality ID of the beam prediction model, then the target configuration information may include the model ID or functionality ID of the beam prediction model, or the target configuration information may not include the model ID or functionality ID of the beam prediction model, which is not limited herein.
[0062] Among them, for the case where the target configuration information does not include the model ID or functionality ID of the beam prediction model, the beam prediction model corresponding to the beam prediction result can be implemented through protocol agreement, protocol predefined, the terminal's independent determination, etc., which is not limited herein.
[0063] In an alternative implementation, in addition to the first indication information, the first LTM CSI reporting configuration may further include at least one of the following 1)-6).
[0064] 1) The number of predicted cells to be reported.
[0065] 2) The number of predicted beams to be reported for each predicted cell.
[0066] 3) The number of measured cells to be reported.
[0067] 4) The number of beams to be reported for each measured cell.
[0068] 5) The total number of measured cells and predicted cells to be reported.
[0069] 6) The total number of measured beams and predicted beams to be reported for each measured cell and each predicted cell.
[0070] Among them, the predicted cells described in the foregoing 1)-6) are cells for which beam quality prediction needs to be performed, and the measured cells are cells for which beam quality measurement needs to be performed.
[0071] Among them, through the configuration of the foregoing 1)-6), the terminal can report beam prediction results and beam measurement results according to the quantities configured in the first LTM CSI reporting configuration.
[0072] The second LTM CSI reporting configuration is used for the terminal to report layer 1 prediction results of serving cells or neighboring cells. In the embodiments of the present application, the second LTM CSI reporting configuration is a newly introduced LTM CSI reporting configuration, which is a different information element (IE) from the foregoing first LTM CSI reporting configuration, so that the terminal can determine whether to carry beam prediction results in the LTM CSI report associated with the second LTM CSI reporting configuration according to whether the second LTM CSI reporting configuration carries or is associated with the first indication information.
[0073] It can be understood that the first indication information carried in the second LTM CSI reporting configuration can be understood as implicit indication information. For example, after the terminal obtains the second LTM CSI reporting configuration, the terminal determines that beam prediction results need to be reported.
[0074] Based on this, in one implementation, the second LTM CSI reporting configuration may include, but is not limited to, at least one of the number of predicted cells to be reported and the number of predicted beams to be reported for each predicted cell. In this case, after the terminal determines that the trigger condition for the reporting configuration is satisfied, the terminal reports a first CSI report according to the second LTM CSI reporting configuration, where only the corresponding number of beam measurement results are included in one reporting instance.
[0075] In an alternative implementation, when reporting the first CSI report, if there are multiple beam prediction results, or if there are multiple beam measurement results and multiple beam prediction results to be reported, then the terminal may use a full-reporting method to report the first CSI report, thereby ensuring the integrity of the reported information.
[0076] Alternatively, the terminal may also use a differential quantization method to report the first CSI report to reduce the overhead of reporting resources. Among them, assuming that the first CSI report includes the beam prediction results but does not include the beam measurement results, when the terminal determines that the number of predicted cells to be reported is greater than 1 (i.e., the number of beam prediction results is greater than 1), or when it determines that the number of predicted beams for each predicted cell is greater than 1, with the maximum value in the beam prediction results as a reference, the beam prediction results in the first CSI report are determined according to the differential quantization method.
[0077] For example, the terminal reports the maximum value of multiple beam prediction results in the first CSI report, and uses the maximum value as a reference to perform differential quantization on the other beam prediction results except the maximum value. The differential reporting rule can reuse the differential reporting rule when reporting the LTM measurement results. It can be understood that: the differential reporting rule when reporting the LTM measurement results mentioned in the context of this application may include but is not limited to: assuming that the maximum L1 measurement result is in the range of [-140, -44] dBm, then the maximum L1 measurement result can be quantized into a 7-bit value with a step size of 1 dB, and the other L1 measurement results except the maximum L1 measurement result are quantized into 4 bits and represented with a 2-bit step size with reference to the L1 measurement result.
[0078] Alternatively, assuming that the first CSI report includes the beam prediction results and the beam measurement results, when the terminal determines that the total number of measurement cells and predicted cells to be reported is greater than 1, or when it determines that the number of predicted beams for each measurement cell or predicted cell is greater than 1, with the maximum value in the beam prediction results and the beam measurement results as a reference, the beam prediction results in the first CSI report are determined according to the differential quantization method.
[0079] For example, the terminal reports the maximum value of multiple beam prediction results and multiple beam measurement results in the first CSI report, and uses the maximum value as a reference to perform differential reporting on the other beam prediction results and beam measurement results except the maximum value. The differential reporting rule can reuse the differential reporting rule when reporting the LTM measurement results.
[0080] In an alternative implementation, when the maximum value is the maximum value in the beam prediction result, the time-frequency resource mapping order corresponding to the first CSI report is to map the beam prediction result first and then map the beam measurement result; or, when the maximum value is the maximum value in the beam measurement result, the time-frequency resource mapping order corresponding to the first CSI report is to map the beam measurement result first and then map the beam prediction result.
[0081] It should be noted that the time-frequency resource mapping order can be implemented by protocol agreement, protocol agreement definition, or network-side device configuration, or can be independently determined by the terminal and then indicate the time-frequency resource mapping order to the network-side device through indication information such as 1 bit, so that the network-side device and the terminal have a consistent understanding of the time-frequency resource mapping order in the first CSI report, ensuring the accuracy of the first CSI report parsing result.
[0082] Among them, the case of indicating the time-frequency resource mapping order to the network-side device through indication information such as 1 bit can be understood as: the first CSI report may further include second indication information, and the second indication information is used to indicate the time-frequency resource mapping order corresponding to the first CSI report.
[0083] In a possible implementation, when the terminal reports the first CSI report, if the reported first CSI report conflicts or collides with the second CSI report or the third CSI report, such as the time-frequency resources corresponding to the first CSI report conflict or collide with the time-frequency resources of the second CSI report or the third CSI report, then the terminal can report according to a predetermined priority rule. Thus, through the definition of the predetermined priority rule, it is possible to clarify the terminal behavior in the event of a time-domain resource conflict or collision, such as making the terminal clear which CSI report to transmit first, ensuring the performance of the communication system. Among them, the second CSI report carries the layer 1 measurement results of the serving cell or neighboring cells, and the third CSI report carries the CSI measurement results of the serving cell.
[0084] Optionally, the predetermined priority rule may include at least one of the following Rules 1 - 4.
[0085] Rule 1: The priority of the first CSI report is higher than the priority of the second CSI report, so as to ensure that the beam prediction result is reported first when the first CSI report conflicts or collides with the second CSI report, avoiding too late cell handover.
[0086] Rule 2: When the inference accuracy of the beam prediction model is lower than the first threshold, the priority of the first CSI report is lower than that of the second CSI report, so as to ensure that the measurement results with higher reliability are reported first, and to avoid the network-side device making a cell handover decision based on unreliable prediction results, resulting in cell handover errors.
[0087] Rule 3: When the inference accuracy of the beam prediction model is not lower than the first threshold, the priority of the first CSI report is higher than that of the second CSI report, so as to ensure that relatively accurate prediction results are reported first and to avoid late cell handover.
[0088] Among them, the first threshold in Rule 2 and Rule 3 can be determined by means such as network-side configuration or protocol predefined, and no limitation is made here.
[0089] In addition, the inference accuracy can be the sum of squares due to error (SSE), mean squared error (MSE), root mean squared error (RMSE) between the beam prediction value and the actually measured beam measurement value, or the inference accuracy can also be cosine similarity, etc., and no limitation is made here.
[0090] Rule 4: The priority of the first CSI report is higher than the priority of the third CSI report, so as to ensure handover performance first.
[0091] In this embodiment, a method for L1 reporting of beam prediction results is provided, which supports reporting the prediction results of beam signal quality to the network-side device through L1.
