[0083] First, the relevant content of this application is introduced.

[0084] (1) Beam prediction

[0085] Refer to Figure 2 , a flowchart of a beam prediction method is shown. As Figure 2As shown in the figure, the beam prediction is performed using an AI method. The reference signal receiving power (RSRP) of some beam pairs is used as the input, and the output of the artificial intelligence (AI) model is the RSRP results of all beam pairs. Here, a beam pair consists of a transmitting beam and a receiving beam. The number of inputs of the AI model is the number of selected partial beam pairs, and the number of outputs is the number of all beam pairs.

[0086] In addition, there is a method to enhance the beam prediction performance. Referring to Figure 3 , a flowchart of another beam prediction method is shown. As Figure 3 shown, correlation information is added on the input side. The correlation information is generally the angle-related information, beam identification (ID) information, etc. corresponding to the selected beam pairs for input. Therefore, the number of inputs of this AI model is still related to the number of selected partial beam pairs, and the number of outputs is still equal to the number of all beam pairs.

[0087] There is also an improved method based on the beam prediction method shown in Figure 2 and Figure 3 . Referring to Figure 4 , a flowchart of yet another beam prediction method is shown. As Figure 4 shown, the desired information can be changed through the AI model to affect the output of the AI model.

[0088] The input types of the AI model include at least one of the following:

[0089] Beam quality-related information;

[0090] Beam information;

[0091] Transmitting beam information at end A;

[0092] Receiving beam information at end B;

[0093] Desired beam information at end B;

[0094] Desired receiving beam information at end B at end B;

[0095] Desired transmitting beam information at end A at end B;

[0096] Time-related information related to beam quality-related information;

[0097] Desired prediction time-related information.

[0098] Optionally, the beam quality information may include, but is not limited to, at least one of the following types: L1 signal-to-noise and interference ratio (L1-SINR), L1 reference signal received power (L1-RSRP), L1-reference signal received quality (L1-RSRQ), L3-SINR, L3-RSRP, L3-RSRQ, etc.

[0099] The beam information may include, but is not limited to, at least one of the following: beam ID information, beam angle information, beam gain information, beam width information, desired information, beam quality information, etc.

[0100] The beam ID information is used to characterize the relevant information for identifying the identity of the beam and may include, but is not limited to, at least one of the following: transmit beam ID, receive beam ID, beam ID, reference signal set ID corresponding to the beam, reference signal resource ID corresponding to the beam, randomly generated unique ID, encoded value after additional AI network processing, beam angle information, resource index information, resource ID, resource set ID, channel state information reference signal resource indicator (CRI), synchronization signal block resource indicator (SSBRI), transmission configuration indication (TCI) state, etc.

[0101] The beam angle information is used to characterize the angle information corresponding to the beam and may include, but is not limited to, at least one of the following: angle information, transmit angle information, receive angle information.

[0102] The angle information is the relevant information used to characterize the angle or identity. For example, angle, radian, index encoded value, ID value, encoded value after additional AI unit processing, etc.

[0103] (2) CSI processing unit

[0104] The CPU in CSI processing (CSI processing units) refers to CSI processing units, that is, the CSI processing unit, rather than the central processing unit.

[0105] The CPU represents the ability of the terminal device to process CSI. When the terminal device performs CSI measurement reporting, resources need to be occupied.

[0106] The UE reports to the network the number of CSI calculations that can be supported simultaneously on one or more carriers. If a UE supports [number] simultaneous CSI calculations, it means that the UE has [number] CSI processing units for processing CSI reporting.

[0107] (3) CSI processing delay

[0108] For aperiodic CSI reporting, it is the CSI reporting triggered by Downlink control information (DCI). Then the time of CSI reporting needs to be no earlier than Z_ref and Z’_ref. Among them, Z_ref is a period of time starting from the first uplink symbol after the last symbol of the Physical Downlink Control Channel (PDCCH) that triggers CSI reporting, including the Cyclic Prefix (CP) length. And Z’_ref is a period of time starting from the first uplink symbol after the last symbol of the aperiodic measurement resource corresponding to the CSI report, including the CP length.

[0109] When the first uplink symbol (including CP) of the Physical Uplink Share Channel (PUSCH) carrying CSI triggered by DCI is earlier than Z_ref, if the PUSCH is not multiplexed with other HARQ-ACK or transport block and other information, the UE ignores the scheduled DCI, that is, the UE does not send the PUSCH.

[0110] When the first uplink symbol (including CP) of the PUSCH carrying CSI triggered by DCI is earlier than Z’_ref, if there is only one triggered report and the PUSCH is not multiplexed with other HARQ-ACK or transport block and other information, the UE ignores the scheduled DCI, that is, the UE does not send the PUSCH. Otherwise, the UE does not update the CSI information of the triggered CSI report.

[0111] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the transmission method provided by the embodiments of the present application will be described in detail.

[0112] The embodiments of the present application provide a transmission method. Referring to Figure 5 , a flowchart of a transmission method provided by the embodiments of the present application is shown. This method is applied to a terminal device. As Figure 5 shown, this method may specifically include:

[0113] Step 101, the terminal device sends first information to the network-side device; or,

[0114] Step 102, when the first condition is met, the terminal device sends second information to the network-side device;

[0115] Wherein, the first information includes a first indication and channel state information;

[0116] The second information includes the channel state information, or the second information includes the first information;

[0117] The first condition is used to indicate that the acquisition process of the channel state information does not meet the processing requirements;

[0118] The first indication satisfies at least one of the following:

[0119] The first indication is used to indicate whether the channel state information is valid;

[0120] The first indication is used to indicate that the channel state information contains a prediction result corresponding to the channel;

[0121] The first indication is used to indicate that the channel state information contains a partial prediction result corresponding to the channel;

[0122] The first indication is used to indicate that the channel state information contains a partial measurement result corresponding to the channel;

[0123] The channel state information includes at least one of the following:

[0124] The prediction result corresponding to the channel;

[0125] The partial prediction result corresponding to the channel;

[0126] The partial measurement result corresponding to the channel.

[0127] It should be noted that channel state information (CSI) is information used to estimate the characteristics of a communication link. The CSI reported by the terminal device to the network-side device can be composed of a rank indication (RI), a precoding type indicator (PTI), a precoding matrix indicator (PMI), and a channel quality indicator (CQI). The time-frequency resources occupied by it are controlled by the network-side device. As an example, the terminal device can obtain CSI by measuring the received downlink reference signals, such as CRS, channel state information-reference signal (CSI-RS), etc., and report it to the network-side device. The network-side device will take the channel quality into account during downlink scheduling.

[0128] The channel in the embodiments of this application can be a downlink channel. The predicted result corresponding to the channel refers to the channel state information predicted by the terminal device at a future time. For example, the terminal device uses multiple AI models to respectively predict the information at different future times, or the information obtained through multiple AI model inferences, the information at multiple different future times, or the information obtained through multiple model inferences, and so on. The partial predicted result corresponding to the channel refers to the partial content corresponding to the channel state information at a future time. For example, if the terminal device uses multiple AI models to jointly predict the channel state information at a future time, then the output of a single AI model is the partial predicted result; or, if the output of the AI model needs to be obtained through multiple AI model inferences, then the result obtained by each AI model inference is the partial predicted result. The partial measurement result corresponding to the channel can be the CSI that has not been fully calculated. For example, the part that has been calculated in the CSI at a certain moment is not reported temporarily.

[0129] Optionally, the above predicted result can be the predicted result obtained by the terminal device through AI model inference, or the predicted result obtained by the terminal device through a time prediction algorithm, etc., which is not limited here.

[0130] The terminal device can directly send the first information to the network-side device, and the first information includes a first indication and CSI. For example, the reporting content of the UE is divided into two parts, part 1 and part 2. The prediction result is reported in part 2, and part 1 is used to indicate that the result is a prediction result. Or, the reporting content of the UE is divided into two parts, part 1 and part 2. Part of the prediction result is reported in part 2, and part 1 is used to indicate that the result is a partial prediction result. Or, the reporting content of the UE is divided into two parts, part 1 and part 2. Part of the measurement result is reported in part 2, and part 1 is used to indicate that the result is a partial measurement result.

[0131] Alternatively, the terminal device can send the second information to the network-side device when the first condition is met. Among them, the first condition is used to indicate that the acquisition process of the channel state information does not meet the processing requirements. For example, it does not meet the processing time requirements corresponding to the timeline, and / or does not meet the requirements for the number of processing units, and so on. The second information can include CSI, or the second information can include the first information, that is, the second information can include a first indication and CSI.

[0132] In the embodiments of the present application, the terminal device can directly report the first indication and CSI to the network-side device synchronously, or the terminal device can also report the first indication and CSI to the network-side device synchronously when the acquisition process of the channel state information does not meet the processing requirements. Based on the first indication, the network-side device can determine whether the CSI report is valid and determine the valid results included in the CSI report, so that the network-side device can clearly know whether the CSI information reported by the terminal device is valid and which part is valid, improving the accuracy of the network-side device in using the CSI information and avoiding waste of uplink resources at the same time. Or, when the acquisition process of the channel state information does not meet the processing requirements, the terminal device can also directly report at least one of the prediction result, the partial prediction result, and the partial measurement result to the network-side device, without the network-side device having to analyze which part of the CSI information is valid.

[0133] Optionally, the method further includes:

[0134] The terminal device performs a first operation when the first condition is met.

[0135] Among them, the first operation includes at least one of the following:

[0136] Reducing the data volume of the input parameters of the first artificial intelligence (AI) model; the first AI model is used to obtain the channel state information;

[0137] Reducing the model complexity of the first AI model;

[0138] Only use N AI models in the first AI model for inferring the channel state information; N is a positive integer;

[0139] Deactivate M AI models in the first AI model, where M is a positive integer.

[0140] In the embodiments of the present application, when the terminal device meets the first condition, it can perform a first operation, thereby reducing the acquisition complexity of the channel state information as much as possible and improving the acquisition efficiency. For example, the terminal device can reduce the amount of data of the input parameters of the first AI model for obtaining CSI, reduce the model complexity of the first AI model, and so on. If the first AI model includes multiple AI models, the terminal device can also deactivate M AI models in the AI models included in the first AI model, thereby reducing the number of models of the first AI model in the active state and reducing the computing resources occupied by CSI acquisition.

[0141] It should be noted that the AI model in the embodiments of the present application can also be referred to as an AI unit, an AI structure, etc., or the AI model can also refer to a processing unit that can implement specific algorithms, formulas, processing flows, capabilities, etc. related to AI, or the AI model can be a processing method, algorithm, function, module or unit for a specific data set, or the AI model can be a processing method, algorithm, function, module or unit running on AI-related hardware such as a Graphics Processing Unit (GPU), a Neuralnetwork Processing Unit (NPU), a Tensor Processing Unit (TPU), an Application Specific Integrated Circuit (ASIC), etc. The present application does not make specific limitations on this. Optionally, the specific data set includes the input and / or output of the AI model.

[0142] Optionally, the identifier of the AI model can be an AI unit identifier, an AI structure identifier, an AI algorithm identifier, or the identifier of a specific data set associated with the AI model, or the identifier of a specific scenario, environment, channel characteristic, device related to the AI, or the identifier of a function, feature, ability or module related to the AI. The present application does not make specific limitations on this.

[0143] Optionally, the method further includes:

[0144] The terminal device sends third information to the network side device.

[0145] Wherein, the third information includes at least one of the following:

[0146] A first identifier, which is used to indicate the number of measurement results included in the channel state information;

[0147] A second identifier, which is used to indicate the number of prediction results included in the channel state information;

[0148] A third identifier, which is used to indicate the number of prediction periods corresponding to the prediction results;

[0149] A fourth identifier, which is used to indicate the prediction period position corresponding to the prediction results.

[0150] In an embodiment of the present application, the terminal device may further indicate, to the network-side device through third information, at least one of the number of measurement results, the number of prediction results, the number of prediction periods corresponding to the prediction results, and the prediction period position included in the CSI.

[0151] It can be understood that the third information in the present application may be included in the first information or the second information. For example, the terminal device may send the first information and the third information to the network-side device through the same signaling, or, when the first condition is met, the terminal device may send the second information and the third information to the network-side device through the same signaling. Of course, the terminal device may also send the first information, the second information, and the third information to the network-side device through different signaling. For example, the terminal device may send the first information to the network-side device through the first signaling, and when the first condition is met, the terminal device may send the second information to the network-side device through the second signaling, and then send the third information to the network-side device through the third signaling, and so on. The embodiments of the present application do not make specific limitations in this regard.

[0152] In an embodiment of the present application, the signaling for transmitting the first information, the second information, and the third information may include, but is not limited to: Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, and so on.

[0153] Optionally, before the terminal device sends the first information to the network-side device, the method further includes:

[0154] The terminal device determines the channel state information to be reported according to the reporting priority of the channel state information; the reporting priority of the channel state information is configured by the network-side device or specified by the protocol.

[0155] In an embodiment of the present application, before reporting CSI, the terminal device may first determine the CSI information to be reported according to the reporting priority of CSI. The reporting priority of CSI may be configured by the network-side device or specified by the protocol. Exemplarily, the reporting priority indication of CSI may indicate some results to be reported preferentially, such as: the results with the most recent time are reported preferentially, the results with the farthest time are reported preferentially, at least one result at a specified time domain position is reported preferentially, the results indicating beam information are reported preferentially, the results with a smaller ID corresponding to the beam information are reported preferentially, the results with a larger ID corresponding to the beam information are reported preferentially, the results with better beam quality corresponding to the beam information are reported preferentially, and so on.

[0156] In the case where the acquisition process of CSI does not meet the processing requirements, in order to better utilize the uplink resources, the results with higher priority may be reported to the network-side device preferentially according to the reporting priority of CSI.

[0157] Optionally, the acquisition process of the channel state information not meeting the processing requirements includes at least one of the following:

[0158] The acquisition process of the channel state information does not meet the processing time requirements;

[0159] The acquisition process of the channel state information does not meet the processing unit quantity requirements.

[0160] In an embodiment of the present application, the acquisition process of CSI not meeting the processing requirements may include at least one of the acquisition process of CSI not meeting the processing time requirements and the processing unit quantity requirements. Among them, the processing unit refers to the unit for acquiring CSI, such as: the unit for measuring CSI, the unit for predicting CSI, the unit for reporting CSI, and so on.

[0161] Optionally, the acquisition process of the channel state information not meeting the processing time requirements includes at least one of the following:

[0162] The acquisition process of the channel state information does not meet the processing time requirements corresponding to the reference signal measurement;

[0163] The acquisition process of the channel state information does not meet the processing time requirements corresponding to the AI model inference.

[0164] Optionally, the acquisition process of the channel state information not meeting the processing unit quantity requirements includes at least one of the following:

[0165] The quantity of the first processing unit used in the acquisition process of the channel state information does not meet the processing unit quantity requirements corresponding to the reference signal measurement; the first processing unit is used for measuring the reference signal;

[0166] The number of second processing units used in the process of obtaining the channel state information does not meet the requirement of the number of processing units corresponding to the AI model inference; the second processing unit is used to run the AI model.

[0169] The number of third processing units is less than the number of first reference processing units; the third processing unit is used to process the channel state information.

[0170] In the embodiments of the present application, if the first moment is earlier than the first reference moment, or the number of third processing units for processing CSI is less than the number of first reference units, it can be determined that the first condition is not met. Among them, the first moment is any processing moment in the process of the terminal device obtaining CSI, and the first reference moment is the reference moment in the time line. The number of first reference units can be specified by the protocol, or configured by the network side device, or can also be configured locally by the terminal device and then reported to the network side device.

[0171] Optionally, the first moment includes at least one of the following:

[0172] The first first target moment of the Physical Uplink Shared Channel (PUSCH) or Physical Uplink Control Channel (PUCCH) carrying the channel state information;

[0174] The moment specified by the protocol.

[0175] Optionally, the first reference moment includes at least one of the following:

[0176] The moment after the first fourth target moment after the last symbol of the Physical Downlink Control Channel (PDCCH) that triggers the terminal device to report the channel state information, after a first time period;

[0179] Optionally, the third processing unit includes at least one of the following:

[0180] The processing unit in the terminal device for reporting channel state information;

[0181] The processing unit in the terminal device for measuring channel state information;

[0182] The processing unit in the terminal device for predicting channel state information;

[0183] The processing unit in the terminal device for running an AI model.

[0184] In summary, for the transmission method provided in the embodiments of the present application, the terminal device can directly synchronously send the first indication and the CSI report to the network-side device. Alternatively, when the acquisition process of the channel state information does not meet the processing requirements, the terminal device can also synchronously report the first indication and the CSI to the network-side device. Based on the first indication, the network-side device can determine whether the CSI report is valid and determine the valid results included in the CSI report, so that the network-side device can clearly know whether the CSI information reported by the terminal device is valid and which part is valid, improving the accuracy of the network-side device in using the CSI information and avoiding waste of uplink resources. Alternatively, when the acquisition process of the channel state information does not meet the processing requirements, the terminal device can directly report at least one of the prediction result, partial prediction result, and partial measurement result to the network-side device, without the network-side device having to analyze which part of the CSI information is valid.

[0185] The embodiments of the present application also provide another transmission method. Referring to Figure 6 , a flowchart of another transmission method provided by the embodiments of the present application is shown. This method is applied to a network-side device. As Figure 6 shown, this method may specifically include:

[0186] Step 201, the network-side device receives the first information or the second information sent by the terminal device.

[0187] Wherein, the first information includes a first indication and channel state information;

[0188] The second information includes the channel state information, or the second information includes the first information;

[0189] The first indication satisfies at least one of the following:

[0190] The first indication is used to indicate whether the channel state information is valid;

[0191] The first indication is used to indicate that the channel state information includes a prediction result corresponding to the channel;

[0192] The first indication is used to indicate that the channel state information includes a partial prediction result corresponding to the channel;

[0193] The first indication is used to indicate that the channel state information includes a partial measurement result corresponding to the channel;

[0194] The channel state information includes at least one of the following:

[0195] The prediction result corresponding to the channel;

[0196] The partial prediction result corresponding to the channel;

[0197] The partial measurement result corresponding to the channel.

[0198] The channel state information reported by the terminal device to the network - side device can be composed of RI, PTI, PMI, and CQI, and the time - frequency resources it occupies are controlled by the network - side device. As an example, the terminal device can obtain CSI by measuring the received downlink reference signals, such as CRS, CSI - RS, etc., and report it to the network - side device. The network - side device will consider the channel quality during downlink scheduling.

[0199] The channel in the embodiments of this application can be a downlink channel, and the prediction result corresponding to the channel refers to the channel state information predicted by the terminal device at a future time. Optionally, the above - mentioned prediction result can be the prediction result obtained by the terminal device through AI model reasoning, or the prediction result obtained by the terminal device through a time prediction algorithm, etc., which is not limited here.

[0200] The partial prediction result corresponding to the channel refers to a partial content corresponding to the channel state information at a future time. For example, if the terminal device uses multiple AI models to jointly predict the channel state information at a future time, then the output of a single AI model is the partial prediction result; or, if the output of the AI model needs to be obtained through multiple AI model inferences, then the result obtained by each AI model inference is the partial prediction result. The partial measurement result corresponding to the channel can be the CSI that has not been fully calculated. For example, for the CSI at a certain moment, the part that has been calculated is reported, and the part that has not been calculated is not reported temporarily.

[0201] In an embodiment of the present application, the terminal device may directly synchronously send the first indication and the CSI report to the network-side device. Alternatively, when the acquisition process of the channel state information does not meet the processing requirements, the terminal device may synchronously report the first indication and the CSI to the network-side device. Based on the first indication, the network-side device can determine whether the CSI report is valid and determine the valid results included in the CSI report, so that the network-side device can clearly know whether the CSI information reported by the terminal device is valid and which part is valid, improving the accuracy of the network-side device in using the CSI information and avoiding waste of uplink resources. Alternatively, when the acquisition process of the channel state information does not meet the processing requirements, the terminal device may directly report at least one of the prediction result, the partial prediction result, and the partial measurement result to the network-side device, without the network-side device having to analyze which part of the CSI information is valid.

[0202] Optionally, the method further includes:

[0203] The network-side device receives the third information sent by the terminal device.

[0204] Wherein, the third information includes at least one of the following:

[0205] A first identifier for indicating the number of measurement results included in the channel state information;

[0206] A second identifier for indicating the number of prediction results included in the channel state information;

[0207] A third identifier for indicating the number of prediction periods corresponding to the prediction result;

[0208] A fourth identifier for indicating the position of the prediction period corresponding to the prediction result.

[0209] In an embodiment of the present application, the terminal device may also use the third information to indicate to the network-side device at least one of the number of measurement results, the number of prediction results, the number of prediction periods corresponding to the prediction result, and the position of the prediction period included in the CSI.

[0210] It can be understood that the third information in this application may be included in the first information or the second information. For example, the terminal device may send the first information and the third information to the network-side device through the same signaling, or the terminal device may, when the first condition is met, send the second information and the third information to the network-side device through the same signaling. Of course, the terminal device may also send the first information, the second information, and the third information to the network-side device through different signaling. For example, the terminal device may send the first information to the network-side device through the first signaling, and when the first condition is met, the terminal device may send the second information to the network-side device through the second signaling and then send the third information to the network-side device through the third signaling, and so on. The embodiments of this application do not make specific limitations on this.

[0211] Optionally, before the network-side device receives the first information or the second information sent by the terminal device, the method further includes:

[0212] The network-side device sends a second indication to the terminal device, and the second indication is used to indicate the reporting priority of the channel state information.

[0213] In the embodiments of this application, the network-side device may also send a second indication to the terminal device to indicate the reporting priority of the CSI. Exemplarily, the CSI reporting priority indication may be partial results that can be reported preferentially, such as: the results with the most recent time are reported preferentially, the results with the farthest time are reported preferentially, at least one result at a specified time domain position is reported preferentially, the results indicating beam information are reported preferentially, the results with a smaller ID corresponding to the beam information are reported preferentially, the results with a larger ID corresponding to the beam information are reported preferentially, the results with better beam quality corresponding to the beam information are reported preferentially, and so on. The terminal device may determine the CSI information to be reported according to the reporting priority of the CSI.

[0214] In summary, for the transmission method provided in this application, the network-side device can determine whether the CSI report is valid and which part is valid based on the first indication included in the received first information or second information, improving the accuracy of the network-side device in using the CSI information. Or, when the network-side device only receives the CSI information, it defaults that the prediction results, partial prediction results, and partial measurement results in the CSI information are valid results, and there is no need to analyze the validity of the CSI information anymore.
