Description

Method and apparatus for wireless communication Technical Field The present application relates to methods and apparatus in a wireless communication system, and more particularly to schemes and apparatus for AI (ARTIFICIAL INTELLIGENCE ) or ML (MACHINE LEARNING, machine learning) in a wireless communication system. Background In conventional wireless communication, channel coding is used to improve reliability of wireless communication, and typical channel coding techniques include Turbo codes, LDPC (Low DENSITY PARITY CHECK Code), polar codes, and the like. With the popularity of AI (ARTIFICIAL INTELLIGENCE ) or ML (MACHINE LEARNING, machine learning) technologies, AI/ML-based coding or decoding technologies have become a research hotspot, such as joint coding technology of sources and channels, cross-layer coding technology, etc. Since the specification of AI models may be beyond 3GPP (except for the reference model for performance calibration), the specific implementation of AI/ML training and AI/ML reasoning may be determined by the hardware vendors and may be based on classical models such as a transducer structure, RNN (Recurrent NeuralNetwork ), CNN (Conventional Neural Networks, convolutional neural network) or a hybrid model consisting of multiple models. Disclosure of Invention The inventors have found through research that in AI/ML based coding techniques, correlation between multiple data blocks may be used for decoding. However, due to the unreliability of data transmission, the transmitter does not determine whether the receiver obtains all the required data blocks during decoding, thereby affecting the coding and decoding performance. In view of the above, the present application discloses a solution. It should be noted that although the motivation of the present application comes from AI/ML-based decoding, the present application is also applicable to conventional non-AI/ML decoding techniques. Especially considering that a specific encoder/decoder algorithm is likely to be non-standardized or self-implemented by the hardware device manufacturer. Furthermore, the implementation complexity can be reduced or the performance can be improved by adopting a unified UE (user equipment) reporting scheme. Embodiments in a first node of the application and features in embodiments may be applied in a second node without conflict. The embodiments of the application and the features of the embodiments may be combined with each other arbitrarily without conflict. Where necessary, the term in the present application may be explained with reference to the description of the specification protocol TS38 series of 3GPP (3 rd Generation Partner Project, third generation partnership project). The application discloses a method used in a first node of wireless communication, which comprises the following steps: Receiving a first wireless channel; wherein the first signaling indicates Q1 data blocks, the Q1 data blocks and the first data block are both inputs of a first encoder, the first encoder is based on AI, an output of the first encoder is used to generate a signal on the first wireless channel, the Q1 data blocks are transmitted prior to the first wireless channel, and the Q1 is a positive integer. It should be noted that, receiving (or transmitting) the first wireless channel is a common expression in the art, which means receiving (or transmitting) the first wireless channel, or means receiving (or transmitting) the signal (e.g., modulation symbol) on the first wireless channel, where the expression is beneficial to be consistent with the common expression in the art. As an embodiment, the above method ensures that the sender of the first wireless channel and the first node have the same understanding about the input of the first encoder, which is beneficial for improving decoding performance. As an embodiment, the sender of the first wireless channel can flexibly indicate the inputted data block for the first encoder, and flexibility can be improved. In particular, according to one aspect of the present application, the above method is characterized in that the input of the first encoder comprises Q sequentially arranged data blocks, the Q1 data blocks are subsets of the Q data blocks, the Q data blocks do not comprise the first data block, and at least one data block of the Q sequentially arranged data blocks does not belong to the Q1 data blocks. As an embodiment, the above method has the advantage that in order to provide more flexibility for the input of the first encoder, i.e. including other data blocks than the Q1 data block being transmitted, the decoding performance can be effectively improved. As an embodiment, the above method is advantageous in that it facilitates maintaining a fixed data structure of the input of the first encoder, reducing the complexity of encoding and decoding. Specifically, according to one aspect of the present application, the method is characterized by comprising: Rec
