Abstract
A method for performing self-interference cancellation by a terminal may comprise the steps of: receiving RS configuration information for phase estimation of self-interference from a base station; when the terminal operates, with a distributed antenna structure, in a full duplex radio (FDR) mode or operates in a space division duplex (SDD) mode between panels, transmitting an RS on the basis of the RS configuration information; and performing phase estimation for self-interference between the panels on the basis of the RS. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, a base station or a network.
