The number and form of the entities are arbitrary. The entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected. The connection may be in any manner, whether direct or indirect, and may be wired or wireless.

[0147] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0148] In some embodiments of the present disclosure, for terminal devices moving at medium to high speeds, due to the rapid changes in channel information in the time domain, if the traditional 3rd Generation Partnership Project (3GPP) Rel-15 / 16 / 17 Type II codebook is still used to feedback Channel Status Information (CSI), system performance will be degraded. To address this problem, the 3GPP Rel-18 standardization introduced the additional codebook of Rel-18 Type II.

[0149] In some embodiments, the Rel-18 Type II codebook uses an existing traditional autoregressive or linear minimum mean squares error (LMMSE) algorithm to predict the downlink channel information at a future time based on the downlink channel information estimated by the terminal side based on historical time points. The precoding information corresponding to the future time point is then calculated based on the predicted downlink channel information. In medium- and high-speed mobility scenarios, the Rel-18 Type II codebook can significantly improve system performance compared to the Rel-16 / 17 Type II codebook.

[0150] In some embodiments, with the development of AI technology, AI has been widely applied to the physical layer of wireless communications. The aforementioned traditional CSI prediction algorithm can also predict future channel information through AI model reasoning. Current simulation evaluations show that AI-based prediction performance outperforms traditional non-AI algorithms.

[0151] In some embodiments, when using AI or non-AI prediction algorithms, CSI at multiple historical moments is required. Downlink channel information is estimated based on the Channel Status Information-Reference Signal (CSI-RS) sent at multiple historical moments. This range (the time range corresponding to multiple historical moments) is called the observation window. The range within which CSI at multiple future moments is predicted (the time range corresponding to multiple future moments) is called the prediction window.

[0152] Figure 1B is a schematic diagram of an observation window and a prediction window according to an embodiment of the present disclosure. As shown in Figure 1B, three observation windows and prediction windows under different parameter configurations are listed. Wherein, N represents the N moments of sending CSI-RS in the observation window, for example, N = 4 / 5 / 8 / 10; M represents the interval of sending CSI-RS in the observation window, for example, M = D = 2.5 / 4 / 5 slots, K represents that there are K moments in the prediction window to predict CSI, for example, K = 1 / 3 / 4 slots, D represents the interval between adjacent moments of predicting CSI in the prediction window, for example, D = 1 / 2.5 / 4 / 5 / 8 slots; the length of the prediction window w d =K·D.

[0153] It should be noted that the observation window and prediction window in FIG1B are for illustration only, and the values ​​of the four parameters N, M, K, and D can be arbitrarily combined, which is not limited in the embodiment of the present disclosure.

[0154] In some embodiments, the AI ​​function or AI model on the UE side can realize function or model identification between the UE and the network (Network, NW) through corresponding function identification or model identification methods.

[0155] In some embodiments, function identification can be achieved by the UE reporting its supported functions to the NW through capability reporting. A function supported by the UE may include one or more artificial intelligence / machine learning (AI / ML) models. Model ID can also be used in life cycle management (LCM) based on function identification.

[0156] In some embodiments, model identification may be achieved by the NW identifying the models supported by the UE through the Model ID, and the UE may indicate the supported models to the NW through the Model ID.

[0157] In some embodiments, model identification must be completed before model inference. UE-side model identification includes the following types:

[0158] (1) Identify NW and UE side models offline

[0159] During the offline identification of the model, the corresponding model can be assigned a corresponding Model ID.

[0160] (2) Model recognition is achieved through air interface signaling, which includes the following two methods:

[0161] Method 1: The UE actively initiates model identification, and the NW can assist in completing the remaining steps of model identification.

[0162] During model identification, the corresponding model can be assigned a corresponding Model ID.

[0163] Method 2: The NW actively initiates model identification, and the UE can assist in completing the remaining steps of model identification.

[0164] During model identification, the corresponding model can be assigned a corresponding Model ID.

[0165] In some embodiments, after completing the relevant function identification or model identification, for an AI model on the UE side, additional conditional information can be used to ensure that the UE side model used for reasoning is consistent with the trained model. The additional conditional information can be conditional information on the NW side or conditional information on the UE side. However, when the additional conditional information corresponds to multiple AI models, the AI ​​model used for reasoning cannot be uniquely determined based on the additional conditional information. For example, in a channel scenario of an urban macro cell (UMa), multiple AI models corresponding to different N, M, D, and K parameter configurations can be trained. Therefore, it is necessary to select one model from multiple models for reasoning.

[0166] In some embodiments, based on model performance monitoring, a model with better performance can be selected from multiple models for inference. Performance monitoring of the CSI prediction model on the UE side includes the following three methods:

[0167] Method 1: UE-side performance monitoring:

[0168] The UE calculates the performance criteria of the AI ​​model based on the measured channel information to monitor the model performance.

[0169] Method 2: NW-side performance monitoring:

[0170] The UE reports the measured channel information to the NW, allowing the NW to calculate the performance criteria of the AI ​​model to monitor the model performance.

[0171] Method 3: Hybrid monitoring on the UE side and the NW side:

[0172] The UE calculates the performance criteria of the AI ​​model based on the measured channel information and reports the performance criteria calculation results to the NW so that the NW can monitor the model performance.

[0173] In some embodiments, AI / ML model performance monitoring based on the UE side and / or NW side is a method for selecting a model, but this method may result in high computational complexity of the UE or high data transmission overhead (a method of hybrid monitoring on the UE side and the NW side). In particular, when there are many AI models on the UE side, the UE needs to traverse and monitor each AI model and calculate the performance indicators of each AI model. The computational complexity of the UE will increase exponentially with the number of AI models on the UE side. Therefore, how the UE selects an AI model or AI function becomes an urgent problem to be solved.

For another example, the terminal device may report the second information to the network device via MAC-CE. For another example, the terminal device may report the second information to the network device via UCI.

[0203] Step S2103: The network device determines fourth indication information according to the second information.

[0204] In some embodiments, the network device may determine the fourth indication information based on the first indication information. For example, the network device may determine at least one of the parameters N, M, K, and D based on the value or value range of TDCP.

[0206] In some embodiments, the network device may determine the fourth indication information based on the seventh indication information. For example, the network device may determine at least one of the parameters N, M, K, and D based on the fifth AI model or the fifth AI function.

[0207] In some embodiments, the network device may also determine the fourth indication information according to multiple of the first indication information, the second indication information, and the seventh indication information.

[0208] Step S2104: The network device sends fourth indication information to the terminal device.

[0209] In some embodiments, the terminal device may receive the fourth indication information. For example, the terminal device may receive the fourth indication information sent by the network device. For another example, the terminal device may also receive the fourth indication information sent by another entity.

[0210] Step S2105: The network device sends third indication information to the terminal device.

[0211] In some embodiments, the third indication information may be used to indicate additional conditions corresponding to the network device.

[0219] For example, the additional condition corresponding to the network device is the channel scenario. Table 1 shows the AI ​​models under different channel scenarios. As shown in Table 1, multiple AI models include A0, B0, C0, A1, B1, C1, A2, B2, and C2. Each channel scenario corresponds to three AI models, among which the AI ​​models corresponding to the UMa scenario include A0, B0, and C0, the AI ​​models corresponding to the UMi scenario include A1, B1, and C1, and the AI ​​models corresponding to the indoor scenario include A2, B2, and C2. If the third indication information is UMa, the terminal device can determine that A0, B0, and C0 are the third AI model from A0, B0, C0, A1, B1, C1, A2, B2, and C2.

[0221] Step S2107: The terminal device determines the first AI model or the first AI function from at least one third AI model or third AI function according to the fourth indication information.

[0222] In some embodiments, the terminal device may determine an AI model that matches the fourth indication information from at least one third AI model as the first AI model.

[0223] In some embodiments, the terminal device may determine an AI function matching the fourth indication information from at least one third AI function as the first AI function.

[0224] For example, if the parameter N corresponding to A0 is 4, the parameter N corresponding to B0 is 5, the parameter N corresponding to C0 is 8, and the fourth indication information is N=5, then B0 can be used as the first AI model.

[0225] In some embodiments, if the third AI model or the third AI function includes one, step S2106 can be omitted, and the third AI model or the third AI function can be used as the first AI model or the first AI function. For example, the third AI model can be used as the first AI model, and the third AI function can be used as the first AI function.

[0485] In some embodiments, the above method may include the method described in the embodiments of the above communication system, terminal equipment, network equipment, etc., which will not be repeated here.

[0486] In some embodiments, the NW can send signaling to query the UE's ability to support the AI ​​function of AI CSI prediction. The UE reports the AI ​​function supported by the UE to the NW based on the received signaling, thus completing the function identification. Alternatively, the model identification has been completed between the UE and the NW through the model identification method. Due to changes in the UE's own hardware conditions or channel environment, the UE can select a suitable AI model based on relevant parameter information associated with the training AI model or additional condition information on the UE / NW side to reduce the number of candidate AI models, thereby reducing the computational complexity of the UE's model selection or reducing the overhead of the UE's feedback monitoring data.

[0487] In some embodiments, the AI ​​function or model selection method for CSI prediction may include the following embodiments:

[0488] Example 1: The trained AI model is associated with at least first parameter information, where the first parameter information characterizes channel characteristics. For example, the first parameter information may be TDCP.

[0489] The first parameter information in Example 2 and Example 1 may correspond to a value or a value range.

[0490] In Example 3, the trained AI model is also associated with at least second parameter information, which may be additional condition information on the UE side or the NW side, or parameter information configured by the network for the terminal. The additional condition information on the UE side may be related hardware information such as the UE's memory or power, and the additional condition information on the NW side may be channel scenarios, data sets, etc. related to the trained AI model.

[0491] Example 4: The UE proactively reports one or more of the following information to the NW through signaling such as RRC / MAC-CE / UCI, or the NW triggers or instructs the UE to report one or more of the following information through signaling such as RRC / MAC-CE / DCI:

[0492] First parameter information calculated by the UE according to the pilot information configured by the network;

[0493] Second parameter information, i.e., additional condition information on the UE side;

[0494] AI functions or models available on the UE side.

[0495] In embodiment 5, the NW reconfigures configuration information related to the AI ​​model to be selected based on one or more information received in embodiment 4.

[0496] Optionally, the NW may also send second parameter information to the UE, that is, additional condition information indicating the NW side.

[0497] Example 6: The UE may select a corresponding AI function or model for inference based on the received configuration information related to the selected AI model or the received second parameter information.

[0498] The following two examples illustrate the model selection method:

[0499] Example 1:

[0500] If the gNB is configured with the parameters N, M, K, and D and the corresponding CSI-RS resources, the UE can complete the collection of data for training the CSI prediction AI model based on the received CSI-RS resources. Due to UE mobility, different movement speeds will result in different time-varying channel characteristics, that is, different TDCPs. Accordingly, the values ​​of the parameters N, M, K, and D may also vary, which will cause the UE to train different models based on these parameter configurations and collected data. Therefore, the trained AI model can be associated with at least one value corresponding to the TDCP.

[0501] The TDCP measurement is obtained by the UE based on the Tracking Reference Signals (TRS) resources configured by the gNB. Based on the received TRS, the UE can calculate the correlation of the time domain channel at different time intervals. The correlation of the time domain channel includes the amplitude value and phase, where the amplitude value is the normalized result and the value range is between 0 and 1. The trained AI model has a certain degree of generalization, and it is not necessary to make each TDCP amplitude value correspond to an AI model, that is, a certain TDCP amplitude range corresponds to an AI model. For example, the UE trained four models A, B, C, and D, and the correspondence between each model and the TDCP amplitude value range is shown in Table 3.

[0502] Table 3

[0503] Optionally, if multiple CSI prediction AI models correspond to the same TDCP amplitude value, the UE or gNB can select the corresponding AI model based on one or more of the configuration parameter information N, M, K, and D.

[0504] Example 2:

[0505] If the gNB is configured with the parameters N, M, K, and D and the corresponding CSI-RS resources, the UE can complete the collection of AI models for training CSI prediction based on the received CSI-RS resources, thereby training AI models corresponding to different parameter configurations. As shown in Example 1, different trained AI models can also be associated with different TDCP amplitude values ​​or amplitude ranges.

[0506] The collected dataset can be a dataset for a specific channel scenario, including UMa, Urban Micro Cell (UMi), indoor, and rural. The channel scenario is conditional information on the gNB side, and different channel scenarios can correspond to different AI models. For example, Table 1 shows the different AI models corresponding to different channel scenarios. Each channel scenario includes three AI models. If the UE does not know the current channel scenario, it will need to select from nine models, significantly increasing the UE's computational complexity. The channel scenario is a condition on the gNB side, and the gNB can send this condition information to the UE via RRC signaling. For example, the current channel scenario can be indicated as UMa using indication information in the RRC signaling. In this way, the UE can select one of A0, B0, and C0 corresponding to the UMa scenario, significantly reducing the UE's computational complexity.

[0507] If a UE's hardware capabilities, such as battery life, degrade during AI model inference, causing it to lose some of the AI ​​models' processing power, the UE will no longer be able to use them. In this case, the UE can proactively report available AI models to the gNB. Alternatively, the gNB can send signaling to query the UE for supported AI models, prompting the UE to report available AI models. Changes in the UE's processing capabilities or hardware capabilities constitute additional conditional information on the UE side. Only after receiving the additional conditional information or available AI models reported by the UE will the gNB configure the corresponding N, M, K, or D parameters based on the received information or the UE's reported AI model. Finally, the UE can select an AI model from a limited set of one or more AI models based on the reconfigured parameters from the gNB and the UE's additional conditional information. This avoids the UE having to select candidate models from a larger number of AI models, thereby reducing the complexity of the UE's model selection process.
