    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). Particularly, a method for operating a UE in a wireless communication system according to various embodiments of the present disclosure may include a step of receiving, from a base station, information indicating that CLI measurement is triggered by identifying the UE as a victim UE, a step of receiving one or more cell-level reference signals from one or more UEs in a second cell adjacent to a first cell in which the UE is positioned, after the CLI measurement is triggered, and a step of transmitting, to the base station, a cell-level measurement report including a result of measuring RSRP of the one or more received cell-level RSs.

    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The present disclosure relates to a method by a transmitting/receiving device, the method enabling: acquiring a time axis digital transmission signal; receiving a reception signal including a self-interference signal; extracting a time axis nonlinear signal sample from the time axis digital transmission signal; converting the time axis digital transmission signal and the time axis nonlinear signal sample into a frequency axis digital transmission signal and a frequency axis nonlinear signal sample; converting the reception signal into a frequency axis digital reception signal; estimating channel information of a self-interference channel, and a nonlinear signal coefficient of the self-interference signal, on the basis of the frequency axis digital transmission signal, the frequency axis nonlinear signal sample and the frequency axis digital reception signal; estimating the self-interference signal on the basis of the channel information and the nonlinear signal coefficient; and carrying out digital self-interference cancellation for the frequency axis digital reception signal by using the self-interference signal.

    Abstract: The present disclosure relates to a 5G or a 6G communication system for supporting higher data rates beyond a 4G communication system such as LTE. The present disclosure provides a method for an AI-based CSI report in a 5G or 6G communication system. The method performed by a base station in a wireless communication system include receiving capability information indicating whether the UE supports generation of AI-based CSI, receiving information on a change in inference time related to the AI-based CSI generation and information on a change in a channel state, based on the capability information, identifying information on a CSI report timing, based on the information on the change in the inference time and the change in the channel state, transmitting RRC configuration information including the CSI report timing, transmitting a CSI-RS, and receiving the CSI report based on the CSI-RS and the information on the CSI report timing.
