    Abstract: The document relates to a method for performing communication using multiple transmission time interval (TTI) structures in a wireless communication system. In this method, a terminal transmits and receives a signal through a resource region in which a first subframe corresponding to a TTI (short TTI) of a first length and a second subframe corresponding to a TTI (short TTI) of a second length longer than the first length are multiplexed in a frequency divisional multiplexing (FDM) manner, and when a second link direction of a signal transmitted through the second subframe in a specific time interval is different from a first link direction of a signal transmitted through the first subframe, the specific time interval of the second subframe is not used for signal transmission in the second link direction.

    Abstract: A method and corresponding user equipment (UE) for configuring a circular buffer in a wireless communication system. The method includes: generating a code block including a payload, a first outer code parity, and a second outer code parity from an input signal based on an outer code in a higher layer; generating a codeword from the code block based on an inner code in a physical layer; and configuring a circular buffer including the codeword and one or more second outer code parities. The first outer code parity is generated based on a first portion of the payload, the one or more second outer code parities, to which an encoding is not applied in the physical layer, are generated based on a second portion of the payload, at least a part of the second portion is different from the first portion, the codeword includes the payload, the first outer code parity, and an inner code parity generated from at least part of the code block based on the inner code, and a number of the one or more second outer code parities in the circular buffer is determined according to a maximum size of the codeword or an amount of resources for transmission.

    Abstract: A method for performing self-interference cancellation (SIC) by an apparatus of a full duplex radio (FDR) mode in a wireless communication system including: performing a channel estimation of a received self-interference reference signal; calculating a power value of two order components of a non-linear self-interference signal based on the channel estimation; and establishing a non-linear digital self-interference cancellation order to be considered in the self-interference cancellation based on the power value of each for the two order components.

    Abstract: The present disclosure relates to a quantum communication system, and specifically to a method and a device for the method, wherein the method comprises the steps of: acquiring configuration information about a quantum signal used for quantum communication; receiving, through a quantum channel, a first block sequence which includes a plurality of first single photons that correspond to the quantum signal, and generating a plurality of second single photons on the basis of the configuration information; inputting, to a beam splitter (BS), the first and second single photons which correspond to each other; and determining whether there is an error in the quantum channel on the basis of the number of detection paths of photons output from the beam splitter.
