    Abstract: An apparatus for removing self-interference in an environment supporting an FDR method according to the present invention may comprise: an analogue self-interference removal unit that is constructed to remove a first analogue self-interference by subtracting a self-interference signal received through a first delay circuit connected between an RF transmission chain and an RF reception chain of the apparatus from a self-interference signal received at a first circuit of the RF reception chain of the apparatus, and that is constructed to remove a second analogue self-interference by subtracting a self-interference signal received through a second delay circuit connected between the RF transmission chain and the RF reception chain of the apparatus from a self-interference signal received at a second circuit of the RF reception chain of the apparatus; and a processor that is constructed to determine whether the first and the second analogue self-interference removals were respectively successful on the basis of the respective residual self-interference signals that are left after removing the first and the second analogue self-interferences.

    Abstract: The present disclosure is an embodiment of a method for operating a terminal, and the method for operating a terminal in a wireless communication system includes requesting, by the terminal, reference signal (RS) group-related configuration information to a base station, receiving RS group-related configuration information from the base station, learning a first parameter related to a meta-learning learning model based on the RS group-related configuration information, and receiving, by the terminal, a RS from the base station or transmitting a RS to the base station based on the first parameter. The RS group-related configuration information includes pattern information, an identifier and a weight value of at least one of a demodulation-reference signal (DM-RS), a phase-tracking reference signal (PTRS), a channel status information-reference signal (CSI-RS), a positioning reference signal (PRS), a synchronization signal block (SSB), a sounding reference signal (SRS), and a meta-learning RS.

    Abstract: A method and a device used in an optical wireless communication (OWC) system are provided. A transmitting terminal transmits a plurality of reference signals to a receiving terminal through each of a plurality of beams. Each of the plurality of beams may have an inhomogeneous polarization beam pattern. The receiving terminal measures signal strength and polarization with respect to the plurality of reference signals. When the receiving terminal transmits feedback information including the measured signal strength information and polarization information to the transmitting terminal, the transmitting terminal may select at least one beam among the plurality of beams on the basis of the feedback information. Alternatively, the receiving terminal may select at least one beam from among the plurality of beams, which corresponds to at least one inhomogeneous polarization beam pattern among a plurality of inhomogeneous polarization beam patterns, on the basis of the measured signal strength and polarization.
