[0143] The embodiments of this disclosure present a channel state information (CSI) reporting method with timestamp information. The AI-based time-domain CSI prediction of the embodiments of this disclosure utilizes time-domain correlation and inputs historical information with timestamps to predict CSI information at future moments, thereby assisting the network in resisting CSI feedback aging and achieving more accurate CSI recovery.

[0144] The embodiments of this disclosure specifically define the feedback report for CSI prediction based on AI / ML. The embodiments of this disclosure also design the time-frequency resource allocation, occupancy, and indication methods for CSI prediction feedback reporting based on AI / ML.

[0146] There is currently no relevant configuration method for CSI reporting in AI / ML-based CSI prediction.

[0147] The embodiments of this disclosure support a variety of flexible configuration schemes for time-frequency resources based on AI / ML-based CSI prediction and for traditional 5G NR services, including partial / full occupation of time-frequency resources and configuration of continuous and discontinuous time-frequency resources. This enables base stations to make flexible and adaptive CSI feedback reporting configurations and adjustments for all UEs / partial UEs / UE groups / individual UEs within the cell coverage area based on information such as the network environment, channel conditions, UE / UE group location movement speed, and inference accuracy of the cell. Thus, the embodiments of this disclosure can, on the one hand, achieve cell-level / UE(group)-level dedicated configurations based on customer / scenario / service requirements for different cell and UE service conditions, and obtain high-precision CSI information; on the other hand, they can also meet the terminal energy-saving requirements by adaptively adjusting the time-frequency resource configuration.

[0148] The embodiments of this disclosure, for CSI reporting types based on AI / ML CSI prediction, select high-precision channel information such as feature vectors and / or full-channel matrices with Doppler information, along with corresponding timestamp information, as the report content. These are then used as input to the CSI predictor to obtain future high-precision CSI information. This effectively solves the problem of outdated CSI information, eliminates the need for additional radio resources, and improves system performance and resource utilization.

[0149] The above embodiments of this disclosure allow the UE to adaptively select reporting methods, including: 1) The UE acquires CSI measurement information operating in multiple frequency bands, co-frequency bands, adjacent frequency bands, and multiple historical moments, and stores it in the UE-side cache. The UE can adaptively select one frequency band and / or one or more moments of CSI from multiple frequency bands to report together; 2) The UE reports one CSI measurement information for each moment of CSI measurement information acquired from multiple frequency bands, co-frequency bands, and adjacent frequency bands. Therefore, the above embodiments of this disclosure allow for flexible multi-frequency collaborative measurement information reporting, enabling AI to intrinsically improve network resource utilization and system performance, meeting the intelligent, high-precision, high-efficiency, and low-power requirements of future 6G ultra-large-scale antenna technology and multi-spectrum fusion technology.

[0150] In addition, the adaptive full-spectrum reporting method of the above embodiments of this disclosure can effectively reduce unnecessary signaling interactions between base stations and terminals, enabling base stations and terminals to use their own resources more rationally and efficiently, and reducing energy consumption.

[0151] The relevant 3GPP has determined to study and design a time-domain CSI prediction scheme based on AI / ML. The above-disclosed embodiment of time-domain CSI prediction based on AI / ML uses CSI information for training during the model training phase. After the model training is completed, inference prediction is performed. This phase does not require frequent CSI information reporting, thereby occupying fewer RB / REs and achieving the goal of saving uplink resources.

[0152] The embodiments disclosed above can be applied to 5G / 6G and wireless AI CSI prediction. For current communication systems, the physical layer is the foundation for ensuring communication services; MIMO is a fundamental supporting technology for the physical layer; and for MIMO, accurately acquiring real-time channel quality and providing effective feedback and efficient utilization are essential key issues. In high-speed mobile scenarios, rapid channel changes caused by Doppler shift will lead to aging of the CSI obtained from channel estimation, resulting in nonlinear channel characteristics. This severely degrades the performance of high-speed mobile communication systems. AI / ML-based channel prediction, because it can predict future CSI in advance and offset delays through time spans, can effectively solve the problems of CSI aging and nonlinearity in high-speed mobile scenarios. Therefore, the embodiments of this disclosure have significant application value.

[0153] The above embodiments of this disclosure mainly address the problem of CSI information reporting by networks and terminals based on AI / ML-based CSI prediction. The above embodiments of this disclosure propose specific design schemes for CSI reporting configuration based on AI / ML and coexistence with traditional CSI reporting.
