摘要： The present specification provides a method for transmitting uplink data (UL data) requiring a low latency in a wireless communication system. The method performed by a terminal comprises: receiving control information related to a contention-based PUSCH zone from a base station; and transmitting uplink data to the base station on the basis of the received control information. The contention-based PUSCH zone is a resource area where uplink data of the terminal can be transmitted without allocation of a UL grant from the base station. Further, in order to distinguish between kinds of specific procedures performed by the terminal, the control information includes procedure-distinguishing information allocated for each kind of the specific procedures.

摘要： A transmission method or a transmission apparatus maps input information of K+n bits to a polar code, encodes the input information on the basis of the polar code, and transmits the encoded input information. The input information includes n parity check bits. n1 bits of the n parity check bits are mapped to least reliable bit positions of K+n bit positions of the polar code, and n−n1 parity check bits (where n−n1>0) are mapped to n−n1 bit positions having a minimum row weight among K+n−n1 bit positions excluding the n1 least reliable bit positions among the K+n bit positions.

摘要： 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.

摘要： In a wireless communication system, a transmission device generates (K+J) bits by adding J cyclic redundancy check (CRC) bits to K information bits, and interleaves the (K+J) bits according to a seed value-based interleaving pattern. The transmission device encodes the bits interleaved according to the interleaving pattern, using a polar code. The seed value permutates the CRC bits, and a value previously determined according to K is used as the seed value.
