[0002] In the Channel State Information (CSI) compression feedback use case based on Artificial Intelligence (AI), the terminal device needs to deploy a CSI construction module, and the network device needs to build a CSI recovery module. The terminal device first measures the downlink channel information through the Channel-state information reference signal (CSI-RS), and then compresses the downlink channel information into CSI information with a certain payload through the CSI construction module, and sends the compressed CSI information to the network device. The network device recovers the received CSI information into downlink channel information through the CSI recovery module. At the same time, the CSI construction module and the CSI recovery module should have a certain correlation, and the ideal two modules can ensure that the recovered downlink channel information is the channel information measured by the terminal device.
[0003] However, in actual applications, the AI model is a data-driven model. When the AI model is used, the CSI compression module and CSI recovery module deployed by the base station and terminal device may no longer match due to changes in the configuration parameters or the scenario, and the performance of the AI model may deteriorate.

[0029] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the technical solution of the present application is further elaborated in detail below in combination with the drawings and specific embodiments of the specification. The attached drawings are for reference only and are not used to limit the embodiments of the present application.
[0030] Unless otherwise defined, all technical and scientific terms used in the embodiments of the present application have the same meaning as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the embodiments of the present application are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.
[0031] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict. It should also be noted that the terms "first / second / third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.
[0032] In the CSI reporting configuration, one CSI reporting configuration is associated with at least one CSI resource configuration for channel measurement. The terminal calculates the CSI based on the configured resources and reports the calculated CSI to the base station based on the reporting configuration. There can be multiple CSI reporting amounts configured at the same time, but generally only one or two CSIs are reported at a time.
[0033] At present, the research content of air interface AI includes wireless AI, which includes three major use cases: CSI feedback, beam management, and positioning, as well as AI model deployment, reasoning, updating, simulation evaluation methods, etc. The research project description (SID) of the air interface AI use case is as follows:
[0034]
[0035] In the related technology, in the AI-based CSI compression feedback use case, the terminal device needs to deploy a CSI construction module, and the network device needs to build a CSI recovery module. The terminal device first measures the downlink channel information through CSI-RS, and then compresses the measured downlink channel information into CSI information with a certain load through the CSI construction module, and further sends this CSI information to the network device. The network device recovers the received CSI information into downlink channel information through the CSI recovery module. At the same time, the CSI construction module and the CSI recovery module should have a certain correlation, and the ideal CSI construction module and CSI recovery module can ensure that the recovered downlink channel information is the channel information measured by the terminal device. The schematic diagram of the CSI compression feedback use case is shown below. Figure 1 As shown. Figure 1 In the process, the collected channel information is restored through the user equipment (UE) and the next generation base station (gNB).
[0036] However, as a data-driven model, AI may cause the CSI compression module and CSI recovery module deployed by the base station and terminal equipment to no longer match due to changes in configuration parameters or scenarios, resulting in poor performance of the AI model, which in turn leads to deviations in the accuracy of channel information recovered based on the AI model, resulting in poor network performance.
[0037] To solve the above problems, the present application provides a method for reporting channel state information, such as Figure 2 As shown, applied to a terminal device, the method may include:
[0038] S101. Receive configuration information about CSI sent by a network device; and determine a first type of CSI and a second type of CSI based on the configuration information.
[0039] In some embodiments, the terminal device may be referred to as a UE. The terminal device may be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and the like. The terminal device may also be a smart phone, a tablet computer, a handheld computer, a mobile station (MS), a mobile terminal, and the like. The terminal device may communicate with one or more network devices via a radio access network (RAN). For example, the terminal device may be a mobile phone (or a "cellular" phone) or a computer with a terminal device, and the terminal device may also be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a wireless access network. The terminal device may also be a handheld device with wireless communication function, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future evolving network, and the embodiments of the present application are not limited thereto.
[0040] In an embodiment of the present application, the network device may be a base station, which is a device that provides wireless communication functions for terminal devices, including but not limited to: Long-Term Evolution (LTE) system, New Radio (NR) system or Licensed-Assisted Access using Long-Term Evolution (LAA-LTE) system, evolutionary base station (evolutional Node B, referred to as eNB or e-NodeB), macro base station, micro base station (also referred to as "small base station"), pico base station, etc.
[0041] In an embodiment of the present application, the configuration information received by the terminal device from the network device may include one or more CSI reports.
[0042] In the embodiment of the present application, one CSI report is supported to include two types of CSI, namely, AI CSI and non-AI CSI.
[0043] It should be noted that, in the embodiment of the present application, the first type of CSI is AI CSI, and the second type of CSI is non-AI CSI.
[0044] It should be noted that the CSI specified by the first type CSI and the second type CSI may also be selected according to actual conditions, and is not specifically limited in the embodiments of the present application.
[0045] In an embodiment of the present application, a CSI report can also be configured, which only includes AI-based CSI, so that the base station can control whether pure AI CSI reporting is performed according to the judgment criteria, such as configuring periodic CSI reporting, activation / deactivation of semi-continuous CSI reporting, and triggering of non-periodic CSI reporting.
[0046] In an embodiment of the present application, the multiple CSI reports may include two CSI reports, wherein one CSI report includes 1 AI CSI, and the other CSI report includes 1 non-AI CSI.
[0047] In the embodiment of the present application, one or more CSI reports are associated with the same CSI-RS resource.
[0048] It should be noted that one CSI report includes two types of CSI, and the resource configurations for calculating the two types of CSI are the same CSI resource configuration associated with the one CSI report.
[0049] In an embodiment of the present application, the configuration information further includes the reporting amount of the second type of CSI, that is, the configuration information includes the reporting amount of non-AI CSI.
[0050] The reported amount of the second type of CSI at least includes a precoding matrix indicator (Precoding Matrix Indicator, PMI).
[0051] In an embodiment of the present application, non-AI CSI reporting includes at least PMI, and the parameter combination configured for this type of CSI can ensure CSI reporting with higher accuracy.
[0052] In an embodiment of the present application, after the terminal device receives the configuration information sent by the network device, because the configuration information configured by the network device includes CSI-RS information for channel measurement, the terminal device performs channel measurement based on the CSI-RS resources sent by the network device, and calculates the corresponding first type CSI and second type CSI, that is, AI-based CSI and non-AI-based CSI can be calculated.
[0053] S102: Report the first type CSI and the second type CSI to a network device.
[0054] In an embodiment of the present application, the terminal device can determine the AI CSI and non-AI CSI that need to be reported corresponding to the configuration information based on the configuration information sent by the network device, and report the determined AI CSI and non-AI CSI to the network device.
[0055] In an embodiment of the present application, when AI CSI and non-AI CSI are reported, the reporting is performed based on the reporting configuration type configured by the network device, and the reporting configuration type may include non-periodic reporting or semi-continuous reporting.
[0056] In the embodiment of the present application, when the first type of CSI and the second type of CSI are reported to the network device, the first type of CSI and the second type of CSI are reported to the network device by periodic reporting, non-periodic reporting or semi-continuous reporting. That is to say, the AI CSI and the non-AI CSI are reported to the network device by periodic reporting, non-periodic reporting or semi-continuous reporting.
[0057] In an embodiment of the present application, when two types of CSI are obtained by different CSI reports, if the time domain behaviors of the two CSI reports are non-periodic, the base station can trigger the two CSI reports through a downlink control information (Downlink Control Information, DCI); if the time domain behaviors of the two CSI reports are semi-continuous, the base station can activate the two CSI reports through a network control unit MAC CE. Among them, the two CSI reports are configured with an association relationship to compare and determine whether the performance of the AI meets the requirements, that is, because the two types of CSI are obtained by two different CSI reports, the association relationship between the two CSI reports needs to be configured so that the two types of CSI reported can be calculated to compare and determine whether the performance of the AI meets the requirements.
[0058] In the embodiment of the present application, the performance of AI can be monitored by a combination of two types of CSI. For example, if it is periodic (P) / semi-persistent (SP) AI CSI + aperiodic (AP) non-AI CSI, it is possible to quickly monitor whether the AI performance is ideal.
[0059] If it is the non-AI CSI of P / SP + the AI CSI of AP, it can be monitored whether the AI mode can be enabled.
[0060] If it is AP's non-AI CSI + AP's AI CSI, it can quickly decide which mode to enable. Among them, the resource configuration associated with the AP's CSI is different from the resource configuration associated with the P / SP CSI CSI, and the P / SP CSI cannot be reused.
[0061] If it is the CSI of non-AI of P / SP + the CSI of AI of P / SP, the performance of AI can be monitored periodically.
[0062] It can be understood that in a channel state information reporting method provided in an embodiment of the present application, the terminal device can determine the first type of CSI and the second type of CSI from the configuration information sent by the network device, and after determining the two types of CSI, send the two types of CSI to the network device. The network device can judge whether the first type of CSI reported by the reporting model is close to the actual channel information based on the first type of CSI and the second type of CSI reported by the terminal device, and then use the judgment result as a basis for judging the impact on network performance, and determine whether to use the reporting model for reporting, so as to ensure the reporting accuracy of the first type of CSI obtained by using the reporting model and ensure the performance of the network.
[0063] In one embodiment of the present application, considering that the uplink resources configured by the network device or the maximum number of available central processing units (CPUs) of the terminal device is limited, it is necessary to design the priority of CSI reporting to ensure that high-priority CSI reports have sufficient uplink resources to carry the CSI reporting amount, or that there are sufficient CPUs to calculate the CSI.
[0064] In an embodiment of the present application, the design of the priority of two types of CSI may include: receiving parameter information about the priority of first type CSI and second type CSI sent by a network device; based on the parameter information, determining a first priority corresponding to the first type CSI and a second priority corresponding to the second type CSI; and determining a priority order according to the first priority and the second priority; and reporting the first type CSI and the second type CSI in order of priority.
[0065] In the embodiment of the present application, the parameter information may include priority information corresponding to the first type of CSI and the second type of CSI. That is, the priority information corresponding to the first type of CSI and the second type of CSI is directly set in the network device, the terminal device receives the priority information sent by the network device, and determines the first priority and the second priority corresponding to the two types of CSI respectively based on the priority information.
[0066] In an embodiment of the present application, the parameter information may also include reporting parameters of CSI reporting corresponding to different types of CSI, and the reporting parameters may include the cell number in the base station, the CSI reporting type, the reporting configuration ID, and whether to report based on AI, etc., and may also include the base station through radio resource control (Radio Resource Control, RRC), MAC control element (MAC Control Element, MAC CE) or DCI indication. That is, the terminal device receives some reporting parameters or parameter information of the indication sent by the network device, and determines the first priority and the second priority corresponding to the two types of CSI respectively.
[0067] In the embodiment of the present application, after obtaining the first priority and the second priority, the priority order of reporting the two types of CSI is determined according to the first priority and the second priority, that is, the CSI with a high priority is reported first, and the CSI with a low priority is reported last.
[0068] In an embodiment of the present application, when a first type of CSI and a second type of CSI are obtained based on the same CSI report, a first priority corresponding to the first type of CSI and a second priority corresponding to the second type of CSI are determined based on parameter information. Priority information about the first priority of the first type of CSI and the second priority of the second type of CSI may be determined from the parameter information; based on the priority information, a first priority corresponding to the first type of CSI and a second priority corresponding to the second type of CSI are determined.
[0069] In an embodiment of the present application, if two types of CSI are obtained based on the same CSI report, the terminal device receives priority information about the first priority of the first type of CSI and the second priority of the second type of CSI configured by the network device, and the priority information includes the first priority corresponding to the first type of CSI and the second priority corresponding to the second type of CSI, then the priorities corresponding to the two types of CSI can be directly determined.
[0070] In an embodiment of the present application, regarding the design of the priorities of the two types of CSI, if the AI CSI priority is higher, then because the AI CSI usually has higher performance than the non-AI CSI, increasing the AI CSI priority can make the base station more likely to obtain higher-precision CSI.
[0071] If the non-AI CSI priority is higher, the non-AI CSI priority is increased. When only this non-AI CSI is reported successfully, the base station can combine this non-AI CSI with another CSI report that only contains pure AI to compare the performance of the AI model.
[0072] In an embodiment of the present application, when a first type of CSI and a second type of CSI are obtained based on two different CSI reports, a first priority corresponding to the first type of CSI and a second priority corresponding to the second type of CSI are determined based on parameter information, and a first CSI reporting parameter of a first CSI report corresponding to the first type of CSI and a second CSI reporting parameter of a second CSI report corresponding to the second type of CSI are determined from the parameter information; wherein the two different CSI reports are associated with each other; a first operation result is determined based on a preset rule and the first CSI reporting parameter; and a second operation result is determined based on the preset rule and the second CSI reporting parameter; when the first operation result is less than the second operation result, a priority order is determined as follows: the first priority of the first type of CSI is higher than the second priority of the second type of CSI; when the first operation result is greater than the second operation result, a priority order is determined as follows: the first priority of the first type of CSI is lower than the second priority of the second type of CSI; when the first operation result is equal to the second operation result, a priority order is determined as follows: the first priority of the first type of CSI is equal to the second priority of the second type of CSI.
[0073] In an embodiment of the present application, when the first type of CSI and the second type of CSI are obtained based on two different CSI reports, the terminal device calculates the first priority and the second priority corresponding to the two types of CSI respectively based on some reporting parameters or indicated parameter information sent by the network device.
[0074] It should be noted that there is a certain association between two different CSI reports, and the resource configurations included in or associated with the two CSI reporting configurations are consistent.
[0075] In an embodiment of the present application, considering that AI-based CSI reporting and non-AI-based CSI reporting may coexist in the network, there will be corresponding rules: the priority of CSI reporting can be calculated according to the formula specified by the preset rules, and is related to the base station cell number (cell ID), CSI reporting type (periodic reporting, non-periodic reporting, semi-continuous reporting carried on the physical uplink control channel (Physical Uplink Control Channel, PUCCH) , Semi-continuous reporting carried on the downlink physical shared channel (Physical Uplink Shared Channel, PUSCH)), reporting configuration ID, and whether the reported CSI is based on AI and other factors; or it may be obtained by the base station through RRC, MAC CE or DCI indication.
[0076] In an embodiment of the present application, the first CSI is used to report the first type of CSI, and the second CSI is used to report the second type of CSI. The first CSI reporting parameter of the first type of CSI and the second CSI reporting parameter of the second type of CSI can be obtained from the parameter information. The first CSI reporting parameter and the second CSI reporting parameter can include the parameter information in the above rules.
[0077] In the embodiment of the present application, the priorities corresponding to the two types of CSI are determined in combination with preset rules and parameter information.
[0078] In one embodiment, in order to improve the priority of the AI-based CSI and ensure that it has a higher chance of occupying CPU or uplink resources, the priority corresponding to a CSI report may be related to whether the CSI is obtained based on AI. Specifically, it can be calculated by the following formula (1):
[0079] Pri iCSI (y,k,c,s,x)=6·N cells ·M s ·x+2·N cells ·M s y+N cells ·M s ·k+M s ·c+s (1)
[0080] Among them, for AI-based CSI reporting, x=0; for non-AI-based CSI reporting, x=1.
[0081] For aperiodic CSI reporting carried on PUSCH, y=0; for semi-persistent CSI reporting carried on PUSCH, y=1; for semi-persistent CSI reporting carried on PUCCH, y=2; for periodic CSI reporting carried on PUCCH, y=3.
[0082] For CSI reporting carrying L1-reference signal received power (RSRP) or L1-signal to interference noise ratio (SINR), k=0; for CSI reporting not carrying L1-RSRP or L1-SINR, k=1.
[0083] c is the serving cell index (Serving Cell Index) configured by high-level signaling, N cells It is the value of the high-level parameter maxNrofServingCells.
[0084] s is the measurement report identifier (reportConfigID) configured by the higher-level signaling. s It is the value of the higher-level parameter maxNrofCSI-ReportConfigurations.
[0085] The first operation result and the second operation result can be calculated by the above formula (1) and the parameter information. The first type of CSI reporting is recorded as CSI reporting #1, and the second type of CSI reporting is recorded as CSI reporting #2. If the first operation result Pri calculated by CSI reporting #1 according to the above formula (1) is iCSI (y, k, c, s, x)#1 is less than the second operation result Pri corresponding to CSI reporting #2 iCSI (y,k,c,s,x)#2, then the first priority corresponding to CSI reporting #1 is higher than the second priority corresponding to CSI reporting #2.
[0086] If the first operation result Pri calculated by CSI reporting #1 according to the above formula (1) is iCSI (y, k, c, s, x)#1 is greater than the second operation result Pri corresponding to CSI reporting #2 iCSI (y,k,c,s,x)#2, then the first priority corresponding to CSI reporting #1 is lower than the second priority corresponding to CSI reporting #2.
[0087] If the first operation result Pri calculated by CSI reporting #1 according to the above formula (1) is iCSI (y, k, c, s, x) #1 is equal to the second operation result Pri corresponding to CSI reporting #2 iCSI (y,k,c,s,x)#2, then the first priority corresponding to CSI reporting #1 is equal to the second priority corresponding to CSI reporting #2.
[0088] In one embodiment, the base station flexibly controls the priority corresponding to a CSI report by indicating the value of a factor in the priority calculation formula corresponding to the CSI report. The priority corresponding to a CSI report can be calculated by the following formula (2):
[0089] Pri iCSI (y,k,c,s,f)=6·N cells ·M s ·f+2·N cells ·M s y+N cells ·M s ·k+M s ·c+s (2)
[0090] Wherein, f is a priority weight factor, which the base station can indicate to the terminal device UE through RRC, MAC CE or DCI.
[0091] It should be noted that the value of f may be related to whether the CSI is obtained based on AI.
[0092] It should be noted that the meanings of the remaining parameters can refer to the meanings indicated in the above formula (1), which will not be repeated here.
[0093] Similarly, the first calculation results and the second calculation results corresponding to the two CSI reports are calculated using formula (2), and the priorities of the two types of CSI are determined based on the first calculation results and the second calculation results.
[0094] It should be noted that the method for determining the two types of CSI priorities based on the first calculation result and the second calculation result can refer to the method of making judgment based on the calculation result in formula (1) in the above embodiment, which will not be repeated here.
[0095] In the embodiment of the present application, after the first priority corresponding to the first type of CSI and the second priority corresponding to the second type of CSI are determined, the first type of CSI and the second type of CSI are reported to the network device in sequence according to the priority order.
[0096] In one embodiment of the present application, the terminal device also needs to determine the first number of bits that the uplink resources configured by the network device can carry, and the second number of bits occupied by the first type of CSI and the second type of CSI reported by the terminal device; if the first number of bits is less than the second number of bits, and the first priority is lower than the second priority, the first type of CSI is discarded; if the first number of bits is less than the second number of bits, and the first priority is higher than the second priority, the second type of CSI is discarded.
[0097] In an embodiment of the present application, if the first number of bits of the available uplink resource limit configured by the network device is less than the second number of bits carried by the AI, the first priority corresponding to the CSI of the AI is lower than the second priority corresponding to the CSI of the non-AI, all the CSI of the AI is discarded, and the CSI of the non-AI is arranged in a traditional priority manner, that is, the CSI of the non-AI is transmitted according to the existing protocol. If the first number of bits of the available uplink resource limit configured by the network device is less than the second number of bits carried by the AI, and the second priority corresponding to the CSI of the non-AI is lower than the first priority corresponding to the CSI of the AI, the CSI of the non-AI is discarded.
[0098] It should be noted that the AI CSI is completely discarded, the non-AI CSI is partially discarded, and the non-AI CSI that is not discarded is arranged according to the traditional priority method.
[0099] In one embodiment of the present application, the terminal device will also send a performance parameter threshold to the network device, wherein the performance parameter threshold is associated with the first type of CSI and / or the second type of CSI, so that the network device determines whether to report CSI based on the performance parameter threshold.
[0100] Based on the above embodiments, the present application also proposes a channel state information reporting method, such as Figure 3 As shown, applied to a network device, the method includes:
[0101] S201. Configure configuration information about CSI, and send the configuration information to a terminal device.
[0102] In an embodiment of the present application, the network device configures the configuration information of the CSI, and the configuration information may include one or more CSI reports.
[0103] In the embodiment of the present application, a CSI report may include two types of CSI, namely, AI CSI and non-AI CSI.
[0104] In an embodiment of the present application, the multiple CSI reports may include two CSI reports, wherein one CSI report includes 1 AI CSI, and the other CSI report includes 1 non-AI CSI.
[0105] In the embodiment of the present application, one or more CSI reports are associated with the same CSI-RS resource.
[0106] In the embodiment of the present application, the configuration information may also include the reporting amount of the second type of CSI.
[0107] The reported amount of the second type of CSI at least includes PMI.
[0108] In an embodiment of the present application, the network device sends the configured configuration information for CSI to the terminal device, so that the terminal device determines the first type of CSI and the second type of CSI to be reported based on the configuration information.
[0109] S202: Receive first-type CSI and second-type CSI reported by a terminal device.
[0110] In an embodiment of the present application, after the terminal device determines the first type of CSI and the second type of CSI to be reported based on the CSI configuration information sent by the network device, the first type of CSI and the second type of CSI are sent to the network device, and the network device determines whether to report the first type of CSI based on the received first type of CSI and second type of CSI.
[0111] In the embodiment of the present application, the network device determines whether to report the first type of CSI based on the first type of CSI and the second type of CSI.
[0112] In an embodiment of the present application, after receiving the first type CSI and the second type CSI sent by the terminal device, the network device also receives a performance parameter threshold sent by the terminal device. The network device determines whether to report the first type CSI based on the performance parameter threshold, the first type CSI and the second type CSI.
[0113] The performance parameter threshold is associated with the first type of CSI and / or the second type of CSI.
[0114] In an embodiment of the present application, the performance parameter threshold is sent by the terminal device to the network device in a reporting manner.
[0115] In an embodiment of the present application, the network device compares the first type CSI and the second type CSI with the performance parameter threshold to determine whether the performance of the AI can meet the CSI reporting conditions. When the performance of the AI meets the requirements, the AI model is used to report the first type CSI. Otherwise, the AI model is not used to report the first type CSI.
[0116] In the embodiment of the present application, based on the performance parameter threshold, the first type CSI and the second type CSI, it is determined whether to report the first type CSI. The first type CSI and the second type CSI can be firstly calculated for Sequential Gaussian Conditional Simulation (SGCS) or Normalized MeanSquare Error (NMSE), and compared with the performance parameter threshold corresponding to SGCS / NMSE. If the SGCS / NMSE of the two types of CSI is less than the performance parameter threshold corresponding to SGCS / NMSE, it indicates that the AI performance cannot meet the requirements and the conditions for CSI reporting are not met, and the first type CSI reporting is not performed. Otherwise, it indicates that the first type CSI reporting can be performed.
[0117] In an embodiment of the present application, the performance parameter threshold may also be pre-configured by the network device, and then based on the preset performance parameter threshold, the first type CSI and the second type CSI pre-configured by the network device, it is determined whether to report the first type CSI.
[0118] It should be noted that the calculation method for determining whether the CSI reporting conditions are met based on the preset performance parameter thresholds, the first type CSI and the second type CSI pre-configured by the network device, and thus determining whether to perform the first type CSI reporting, can refer to the above embodiment and will not be repeated here.
[0119] In an embodiment of the present application, the result of comparing the SGCS / NMSE corresponding to the first type of CSI and the second type of CSI with the performance parameter threshold corresponding to the SGCS / NMSE can be a long-term statistical result, and the network device determines whether the performance of the AI meets the requirements based on the long-term statistical result.
[0120] In the embodiment of the present application, the performance of the AI model is effectively monitored by the detection method set, which can help the network to manage the life cycle of the model, including activation / deactivation, switching, and fallback of the model. By monitoring whether the CSI recovered by the AI-based model is close enough to the real channel or the measured channel, it is ensured that the deployed model can be used to obtain channel information with sufficient accuracy, thereby ensuring network performance.
[0121] In one embodiment of the present application, a network device configures parameter information about the priorities of a first type of CSI and a second type of CSI, and sends the parameter information to a terminal device; so that the terminal device can determine a first priority corresponding to the first type of CSI and a second priority corresponding to the second type of CSI based on the parameter information; and determine a priority order according to the first priority and the second priority.
[0122] In the embodiment of the present application, the parameter information may include priority information corresponding to the first type of CSI and the second type of CSI. That is, the priority information corresponding to the first type of CSI and the second type of CSI is directly set in the network device, the terminal device receives the priority information sent by the network device, and determines the first priority and the second priority corresponding to the two types of CSI respectively based on the priority information.
[0123] In the embodiment of the present application, the parameter information may also include reporting parameters of CSI reporting corresponding to different types of CSI, and the reporting parameters may include the cell number in the base station, the CSI reporting type, the reporting configuration ID, and whether to report based on AI, etc., and may also include the base station through RRC, MAC CE or DCI indication. That is, the terminal device receives some reporting parameters or indicated parameter information sent by the network device, and determines the first priority and the second priority corresponding to the two types of CSI respectively.
[0124] In an embodiment of the present application, the network device configures the above-mentioned parameter information and sends the above-mentioned parameter information to the terminal device, and the terminal device can determine the first priority corresponding to the first type of CSI and the second priority corresponding to the second type of CSI according to the configured parameter information; and determine the priority order according to the first priority and the second priority.
[0125] In one embodiment of the present application, when the first type of CSI and the second type of CSI are obtained based on the same CSI report, priority information about the first type of CSI and the second priority of the second type of CSI are configured in the parameter information, and the parameter information is sent to the terminal device, so that the terminal device can determine the first priority corresponding to the first type of CSI and the second priority corresponding to the second type of CSI based on the parameter information; and determine the priority order according to the first priority and the second priority.
[0126] In an embodiment of the present application, if the first type of CSI and the second type of CSI are obtained based on the same CSI report, the network device can directly configure priority information about the two types of CSI and send the priority information to the terminal device.
[0127] In an embodiment of the present application, when the first type of CSI and the second type of CSI are obtained based on two different CSI reports, a first CSI reporting parameter of a first CSI report corresponding to the first type of CSI and a second CSI reporting parameter of a second CSI report corresponding to the second type of CSI are configured in the parameter information; and the first CSI reporting parameter and the second CSI reporting parameter are sent to a terminal device, so that the terminal device determines a first priority corresponding to the first type of CSI and a second priority corresponding to the second type of CSI based on the first CSI reporting parameter and the second CSI reporting parameter; and determines a priority order according to the first priority and the second priority.
[0128] In an embodiment of the present application, if the first type of CSI and the second type of CSI are obtained based on different CSI reports, the network device configures reporting parameters or indication parameter information and sends it to the terminal device. Among them, the reporting parameters may include factors such as the base station cell number, CSI reporting type (periodic reporting, non-periodic reporting, semi-continuous reporting on PUCCH, semi-continuous reporting on PUSCH), reporting configuration ID, and whether the reported CSI is based on AI; or it may be obtained by the base station through RRC, MAC CE or DCI indication. The terminal determines the priority of the first type of CSI and the second type of CSI according to the reporting parameters.
[0129] In one embodiment of the present application, a network device configures uplink resources, where the uplink resources are used for a terminal device to determine whether to discard a first type of CSI or a second type of CSI based on a first number of bits that the uplink resources can carry.
[0130] In an embodiment of the present application, the network device can configure the first number of bits that can be carried according to actual conditions, and send the configured first number of bits to the terminal device.
[0131] The first number of bits may be the maximum number of bits that the network device can carry.
[0132] It should be noted that the implementation process of the terminal device determining whether to discard the first type of CSI or the second type of CSI based on the first number of bits that the uplink resource can carry can refer to the above embodiment and will not be repeated here.
[0133] It can be understood that in a channel state information reporting method provided in an embodiment of the present application, the terminal device can determine the first type of CSI and the second type of CSI from the configuration information sent by the network device, and after determining the two types of CSI, send the two types of CSI to the network device. The network device can judge whether the first type of CSI reported by the reporting model is close to the actual channel information based on the first type of CSI and the second type of CSI reported by the terminal device, and then use the judgment result as a basis for judging the impact on network performance, and determine whether to use the reporting model for reporting, so as to ensure the reporting accuracy of the first type of CSI obtained by using the reporting model and ensure the performance of the network.
[0134] Based on the above embodiments, through a smaller reference signal and CSI reporting overhead, it is possible to monitor whether the CSI recovered by the AI-based model is close enough to the real channel or the measured channel. If the CSI accuracy is insufficient, you can choose to switch to another model, or update the model, or roll back the model (switch to the traditional CSI reporting method) to ensure that the network can obtain channel information with sufficient accuracy, thereby ensuring network performance.
