Abstract: A method of low-density parity check (LDPC) code encoding and an apparatus therefor are disclosed. The LDPC code encoding method includes determining whether code block cyclic redundancy check (CRC) is attached to a code block based on a channel state or a required error rate. Signal overhead is reduced via selective application of the code block CRC.

Abstract: A method for a transmission and reception point (TRP) for controlling cross-link interference comprises the steps of: determining a timing advance (TA) value, for measuring or eliminating cross-link interference, in a set subframe if a section in which cross-link interferences occur between the TRP and one or more adjacent TRPs is configured; and transmitting the determined TA value in the set subframe to a terminal, wherein the section in which cross-link interference occurs can correspond to a section that is configured as an uplink section for the TRP, and as a downlink transmission section for the one or more adjacent TRPs.

Abstract: A method by which a first base station removes remote cross-link interference (CLI) can comprise: detecting the occurrence of a remote CLI; broadcasting a first reference signal including information on the first base station, on the basis of the detection of the occurrence of the remote CLI; obtaining information on a second base station; and determining that the remote CLI occurs, based on the information on the second base station. The first base station broadcasts the first reference signal, and the second base station, having received the first reference signal, can determine whether the occurrence of the remote CLI of the first base station is caused, based on the first reference signal.

Abstract: Provided are a method and a device for performing communication using a non-orthogonal code multiple access scheme in a wireless communication system. Specifically, 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, a second reference signal, a third reference signal and a fourth reference signal. On the basis of 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. The first reference signal is selected on the basis of the first field and the maximum number of reference signals. The second reference signal is selected on the basis of the second field and the maximum number of reference signals. The third reference signal is selected on the basis of the third field and the maximum number of reference signals. The fourth reference signal is selected on the basis of the second field and the maximum number of reference signals.
