[0035] The technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0036] Figure 2 is a flow chart of a method 200 for reporting channel state information according to an exemplary embodiment of the present application. This method 200 may be, but is not limited to, executed by a terminal, specifically by at least one of hardware and software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.
[0037] S210: The terminal obtains target configuration information.
[0038] Among them, the target configuration information carries or is associated with first indication 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 that introduces AI or ML assistance, this application can determine whether the terminal needs to report the beam prediction result based on the target configuration information. If the target configuration information carries the first indication information, it can be determined that the terminal needs to report the beam prediction result. Otherwise, it is not necessary to report the beam prediction result.
[0039] It can be understood that the beam prediction result is determined based on a beam prediction model, such as using the historical measurement data of the predicted cell as the input of the beam prediction model to predict the beam prediction result corresponding to the predicted cell, or using the beam measurement result currently actually measured in the measured cell as the input of the beam prediction model to predict the beam prediction result of the measured cell, without limitation here. The beam prediction model is obtained based on training of an AI model or an ML model. The predicted cell mentioned in the context of this application can be understood as a cell that requires beam quality prediction, such as a serving cell, a neighboring cell, an LTM candidate cell, etc., and the measured cell can be understood as a cell that requires beam quality measurement, such as a serving cell, a neighboring cell, an LTM candidate cell, etc. In addition, the predicted cell and the measured cell can be the same or different. For example, when the predicted cell is the same as the measured cell, it can be determined that the terminal needs to perform beam quality measurement based on the predicted cell and also perform beam quality prediction.
[0040] In this case, as an optional implementation method, the target configuration information can reuse the configuration information in the related technology and introduce the first indication information therein, or it can be newly introduced configuration information, which is not limited in this embodiment.
[0041] In addition, there may be multiple ways for the terminal to obtain the target configuration information. For example, the terminal may obtain the target configuration information from the network side device, or may obtain the target configuration information through a protocol agreement or a predefined method, which is not limited here.
[0042] It is worth noting that the AI model mentioned in the context of this application may 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 function, etc., or the AI model may also refer to a processing unit that can implement specific algorithms, formulas, processing procedures, capabilities, etc. related to AI, or the AI model may also be a processing method, algorithm, function, module or unit for a specific data set, or the AI model may 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 processor (NPU), a tensor processing unit (TPU), an application specific integrated circuit (ASIC), etc., and this application does not make specific limitations on this. Optionally, the specific data set includes at least one of the input and output of the AI unit / AI model.
[0043] Optionally, the AI model identifier may be the identifier of the ML model, the AI structure identifier, the AI algorithm identifier, or the identifier of a specific data set associated with the AI unit / AI model, or the identifier of a specific scenario, environment, channel feature, or device related to the AI / ML, or the identifier of a function, feature, capability, or module related to the AI / ML. This application does not specifically limit this.
[0044] AI functionality can be understood as an AI algorithm function, which may include multiple AI models.
[0045] S220: The terminal sends a first channel state information (CSI) report according to the first indication information.
[0046] Among them, the reporting of the first CSI report can also be understood as the reporting of the layer 1 measurement results and layer 1 prediction results of the serving cell, neighboring cell or LTM candidate cell, which can be used by network-side equipment to perform channel quality assessment, cell switching, etc. The layer 1 prediction results may include but are not limited to beam prediction results.
[0047] The terminal sends the first CSI report according to the first indication information, which 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.
[0048] Of course, in a possible implementation, the first CSI report may also include beam measurement results obtained by actual measurement, etc.
[0049] Based on this, in this embodiment, a 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 here.
[0050] In this embodiment, the terminal obtains target configuration information carrying first indication information and sends a first CSI report based on the first indication information, wherein 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 based on the beam prediction model reasoning. As a result, after introducing AI- or ML-assisted LTM enhancement, it is possible to report the beam prediction results of the serving cell or neighboring cell.
[0051] Figure 3 is a flow chart of a channel state information reporting method 300 provided in an exemplary embodiment of the present application. This method 300 may be, but is not limited to, executed by a terminal, specifically by at least one of hardware and software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.
[0052] S310: The terminal obtains target configuration information.
[0053] The target configuration information carries first indication information, and the first indication information is used to instruct the terminal to report the beam prediction result.
[0054] S320, the terminal sends a first CSI report according to the first indication information.
[0055] The first CSI report includes a beam prediction result obtained based on reasoning of a beam prediction model.
[0056] It can be understood that the implementation process of S310-S320 can refer to the relevant description in the aforementioned method embodiment 200. Of course, in addition to referring to the aforementioned method embodiment 200, as a possible implementation method, the target configuration information may include at least one of the LTM CSI resource configuration (LTM-CSI-ResourceConfig), the first LTM CSI reporting configuration (LTM-CSI-ReportConfig), and the second LTM CSI reporting configuration.
[0057] The LTM CSI resource configuration is used to configure relevant resources for layer 1 CSI measurement of a serving cell or a neighboring cell, and may be associated with a reference signal configuration (RS Config). In an embodiment of the present application, the LTM CSI resource configuration may also be associated with the first indication information, or the first indication information may be carried in the LTM CSI resource configuration, so that the terminal may determine whether to carry a beam prediction result in an LTM CSI report corresponding to the LTM CSI reporting configuration associated with the LTM CSI resource based on whether the LTM CSI resource configuration carries or is associated with the first indication information.
[0058] It is worth noting that if the target configuration information is the LTM CSI resource configuration, this indicates that all CSI reports associated with the LTM CSI resource configuration need to report the beam prediction result. In other words, if 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 first CSI report carries the beam prediction result.
[0059] The first LTM CSI reporting configuration is used by the terminal to report layer 1 measurement results of a serving cell or a neighboring cell. If the first LTM CSI reporting configuration is configured with related configurations of reporting resources and reporting content, it can be associated with the LTM CSI resource configuration. In an embodiment of the present application, the LTM CSI reporting configuration can also be associated with the first indication information, or the first indication information can be 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 based on whether the first LTM CSI reporting configuration carries or is associated with the first indication information.
[0060] It is worth noting that if the target configuration information is the first LTM CSI reporting configuration, it indicates 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.
[0061] Based on this, in an optional implementation, for the target configuration information being the LTM CSI resource configuration and the first LTM CSI reporting configuration, there may be multiple implementation methods for the first indication information carried therein. For example, the first indication information may be newly introduced information for explicitly indicating that the terminal reports the beam prediction result; other information may also be multiplexed to implicitly indicate that the terminal reports the beam prediction result, such as the model identifier (model ID) or function ID (functionality ID) of the beam prediction model may be multiplexed, so that when the LTM CSI resource configuration and the first LTM CSI reporting configuration include the model identifier or function ID of the beam prediction model, it can be determined that the terminal needs to report the beam prediction result.
[0062] It is worth noting that when the first indication information reuses the model identification ID or function ID of the beam prediction model, the model identification ID or function ID of the beam prediction model is also used to indicate that the beam prediction result that the terminal needs to report is determined based on the beam prediction model corresponding to the model identification ID or function ID.
[0063] Of course, for the situation where the first indication information explicitly instructs the terminal to report the beam prediction result, if the first indication information is other information in addition to the model ID or function ID of the beam prediction model, then the target configuration information may include the model ID or function ID of the beam prediction model, or the target configuration information may not include the model ID or function ID of the beam prediction model, and there is no limitation here.
[0064] Among them, in the case where the target configuration information does not include the model ID or function ID of the beam prediction model, the beam prediction model corresponding to the beam prediction result can be implemented through protocol agreement or protocol pre-definition, autonomous determination by the terminal, etc., and no restrictions are made here.
[0065] In an optional 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).
[0066] 1) The number of predicted cells that need to be reported.
[0067] 2) The number of predicted beams that each predicted cell needs to report.
[0068] 3) The number of measurement cells that need to be reported.
[0069] 4) The number of beams that need to be reported for each measurement cell.
[0070] 5) The total number of measurement cells and prediction cells that need to be reported.
[0071] 6) The total number of measurement beams and prediction beams that need to be reported by each measurement cell and each prediction cell.
[0072] Among them, the predicted cell described in the above 1)-6) is a cell that needs to perform beam quality prediction, and the measurement cell is a cell that needs to perform beam quality measurement.
[0073] Among them, through the configuration of 1)-6), the terminal can report the beam prediction results and beam measurement results according to the quantity configured in the first LTM CSI reporting configuration.
[0074] The second LTM CSI reporting configuration is used by the terminal to report the layer 1 prediction result of the serving cell or the neighboring cell. In the embodiment of the present application, the second LTM CSI reporting configuration is a newly introduced LTM CSI reporting configuration, which is a different pheromone (IE) from the aforementioned first 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 second LTM CSI reporting configuration based on whether the second LTM CSI reporting configuration carries or is associated with the first indication information.
[0075] 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 the beam prediction result needs to be reported.
[0076] 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 determining that the triggering conditions for the reporting configuration are met, the terminal may report the first CSI report according to the second LTM CSI reporting configuration, where only the corresponding number of beam measurement results are included in a single reporting instance.
[0077] In an optional implementation, when reporting the first CSI report, if there are multiple beam prediction results, or there are multiple beam measurement results and multiple beam prediction results that need to be reported, then the terminal can use a full reporting method to report the first CSI report, thereby ensuring the integrity of the reported information.
[0078] Alternatively, the terminal may also report the first CSI report using a differential quantization method to reduce the overhead of reporting resources. Assuming that the first CSI report includes the beam prediction result but does not include the beam measurement result, when the terminal determines that the number of predicted cells that need to be reported is greater than 1 (such as the number of beam prediction results is greater than 1), or when it is determined that the number of predicted beams for each predicted cell is greater than 1, the terminal uses the maximum value of the beam prediction results as a reference and determines the beam prediction result in the first CSI report using a differential quantization method.
[0079] 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 beam prediction results other than the maximum value. The differential reporting rule can reuse the differential reporting rule for reporting the LTM measurement result. It is understandable that the differential reporting rule for reporting the LTM measurement result 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 to 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 to 4 bits and represented with a step size of 2 bits with reference to the L1 measurement result.
[0080] Alternatively, assuming that the first CSI report includes the beam prediction result and the beam measurement result, the terminal may, when determining that the total number of measured cells and predicted cells that need to be reported is greater than 1, or when determining that the number of predicted beams for each measured cell or predicted cell is greater than 1, use the maximum value of the beam prediction result and the beam measurement result as a reference and determine the beam prediction result in the first CSI report in a differential quantization manner.
[0081] 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 differentially report other beam prediction results and beam measurement results except the maximum value. The differential reporting rules can reuse the differential reporting rules when reporting LTM measurement results.
[0082] In an optional implementation, when the maximum value is the maximum value among the beam prediction results, 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 among the beam measurement results, 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.
[0083] It is worth noting that the time-frequency resource mapping order can be achieved by protocol agreement, protocol definition, and network side device configuration, or it can be determined autonomously by the terminal and then indicated to the network side device through an indication message 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, thereby ensuring the accuracy of the first CSI report parsing result.
[0084] Among them, the situation where the time-frequency resource mapping order is indicated to the network side device through an indication information such as 1 bit can be understood as: the first CSI report can also 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.
[0085] In one 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 if 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 may report according to a predetermined priority rule. Thus, by defining a predetermined priority rule, it is possible to clarify terminal behavior in the event of a time domain resource conflict or collision, such as making it clear to the terminal which CSI report to transmit first, thereby ensuring the performance of the communication system. The second CSI report carries the layer 1 measurement result of the serving cell or the neighboring cell, and the third CSI report carries the CSI measurement result of the serving cell.
[0086] Optionally, the predetermined priority rule may include but is not limited to at least one of the following rules 1 to 4.
[0087] Rule 1: The priority of the first CSI report is higher than the priority of the second CSI report, so that when the first CSI report conflicts or collides with the second CSI report, the beam prediction result is reported first to avoid cell switching too late.
[0088] 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, thereby ensuring that measurement results with higher reliability are reported first, avoiding the network side equipment making cell switching decisions based on unreliable prediction results, resulting in cell switching errors.
[0089] 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 the second CSI report, thereby ensuring that more accurate prediction results are reported first and avoiding late cell switching.
[0090] The first threshold in Rule 2 and Rule 3 may be determined by network-side configuration or protocol pre-definition, and is not limited here.
[0091] In addition, the inference accuracy can be the sum of squares due to error (SSE), mean squared error (MSE), or root mean squared error (RMSE) between the beam prediction value and the actual measured beam measurement value, or the inference accuracy can also be cosine similarity, etc., which is not limited here.
[0092] Rule 4: The priority of the first CSI report is higher than the priority of the third CSI report, so as to prioritize handover performance.
[0093] In this embodiment, an L1 reporting method for beam prediction results is provided, which supports reporting the prediction results of beam signal quality to the network side device through L1.
