Abstract: Disclosed herein is a concatenated code encoding method for improving a turbo code. The concatenated code encoding method of the present disclosure includes encoding an input signal based on a repetition-accumulation (RA) code as an outer code, adding a tail bit to the encoded input signal, and encoding the encoded input signal based on the a turbo code. The concatenated code encoding method may further include interleaving the encoded input signal after application of the outer code.

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 of transmitting a signal by adaptively controlling windowing or filtering by a user equipment in a wireless communication system, includes the steps of receiving a message including a timing advance (TA) value from a base station, determining a windowing type or a filtering type corresponding to the TA value, and transmitting an uplink signal to which the determined windowing type is applied. In this case, the windowing type is distinguished according to a length of a valid symbol and the filtering type can be distinguished according to a filter coefficient value.

Abstract: An improved layered decoding method for a low density parity check (LDPC) code and a device therefor are disclosed. Disclosed is the layered decoding method for an LDPC code, capable of determining whether decoding is successful by performing a syndrome check on each check node at every variable node update. In addition, the syndrome check can be performed by using reduced variable nodes, thereby reducing decoding power consumption and decoding time consumption.

Abstract: Provided are a method and a device for performing communication using a non-orthogonal code multiple access scheme in a wireless communication system. A terminal divides a terminal identifier into a first field, a second field, a third field and a fourth field and selects a first reference signal based on the first field and a maximum number of reference signals, a second reference signal based on the second field and the maximum number of reference signals, a third reference signal based on the third field and the maximum number of reference signals, and a fourth reference signal based on the fourth field and the maximum number of reference signals. Based on the first reference signal, the second reference signal, the third reference signal or the fourth reference signal, the terminal transmits contention-based data to a base station.
