    Abstract: A data retransmission method for a polar code, and a device therefor are disclosed. The data retransmission method of the disclosure can comprise the steps of: generating a first data block by allocating a plurality of data bits to input bits, with high priorities, among input bits of a polar code encoding module on the basis of a target encoding rate; transmitting the generated first data block; generating a second data block by allocating first data bits among the plurality of data bits to input bits, with low priorities, among the input bits of the polar code encoding module, on the basis of the target encoding rate and shortening bits; and transmitting the generated second data block as a retransmission of the first data block.

    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: In an aspect of the present invention, provided is a method for measuring a position of a mobile device by reference devices in a wireless communication system. In this case, the method may include: receiving, by a first reference device, reference signals at first and second frequencies from the mobile device; obtaining first phase difference information based on the reference signals received at the first and second frequencies; receiving, by the first reference device, second phase difference information from a second reference device; and measuring the position of the mobile device based on the first and second phase difference information.

    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.
