Description

Method and apparatus in a node for wireless communication Technical Field The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a scheme and apparatus related to CSI (Channel Status Information, channel state information) in a wireless communication system. Background In conventional wireless communications, a UE (User Equipment) reports various auxiliary information, such as channel information, beam Management (Beam Management) related auxiliary information, positioning related auxiliary information, and so on, obtained by measuring downlink signals and/or channels. Wherein the CSI (Channel Status Information, channel state information) includes, but is not limited to, one or more of CRI (CSI-RS Resource Indicator, channel state information reference signal resource indication), RI (Rank Indicator), PMI (Precoding Matrix Indicator, precoding indication), CQI (Channel quality Indicator, channel quality indication), or L1-RSRP (Layer 1Reference Signal Received Power ). The UE may use this information itself to select the appropriate transmission parameters or report this information. The network device selects appropriate transmission parameters for the UE according to the UE reporting, such as parameters of the camping cell, MCS (Modulation and Coding Scheme, modulation coding scheme), TPMI (TransmittedPrecoding Matrix Indicator, transmit precoding matrix indication), TCI (Transmission Configuration Indication, transmit configuration indication), and the like. In addition, UE reporting may be used to optimize network parameters, such as better cell coverage, switching base stations based on UE location, etc. In conventional cellular communications, antenna ports (AntennaPort) are used to describe reference signal resources, and unlike physical antennas, antenna ports can be considered as virtualized/overlapping operations of physical antennas. In NR (release) 18, research on AI (ARTIFICIAL INTELLIGENCE )/ML (MACHINE LEARNING, machine learning) technology is standing to investigate its effect on system performance and system design. AI/ML technology may also play an important role in future 6G communications. In contrast to conventional approaches, AI/ML has characteristics based on training and deployment requirements. According to 3GPP standard TS38.300, the AI/ML model and algorithms are beyond the scope of 3GPP (third Generation partnership project). At RAN (Radio Access Network) bis conferences of Working Group 1, support functions (Supported Functionality) and applicable functions (Applicable Functionality) are passed, wherein the support functions are indicated in the UE capability report, the applicable functions are determined by the UE based on additional conditions on the network side (network side additional condition) and on the UE side (INFERENCE CONFIGURATION) and are indicated to the network, the applicable functions generally meaning that a corresponding AI model is available, or that a corresponding reasoning configuration (INFERENCE CONFIGURATION) can be activated/executed. Disclosure of Invention The applicant finds through research that the existing indication mechanism of the applicable function cannot timely reflect the change of the additional condition of the UE side, and further cannot execute optimal reasoning configuration. 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 the application of the AI/ML model and a number of embodiments are directed to AI/ML expansion, the present application is applicable to other schemes, such as conventional reception algorithms/schemes. Although the description of some AI/ML models and algorithms is referred to in the present specification, those of ordinary skill in the art will appreciate that such descriptions are not necessary or alternative to wireless cellular communication-related solutions. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to AI/ML based schemes and traditional reception algorithms/schemes) also helps to reduce signaling overhead/complexity, hardware complexity and cost. Embodiments in a first node of the application and features in embodiments may be applied to a second node and vice versa without conflict. The embodiments of the application and the features of the embodiments may be combined with each other arbitrarily without conflict. Furthermore, although some embodiments of the present application are described based on the 5G protocol, the present application is applicable to the communication standard after 5G without conflict. The term in the present application is explained with reference to the definition of the specification protocol TS38 series of 3GPP or the definition of the specification protocol TS28 series of 3GPP, as required. The application discloses a method used in a fi
