Abstract: The present disclosure provides a method for transmitting a random access channel (RACH) by a UE in a wireless communication system. Particularly, the method includes receiving information about actually transmitted synchronization signal blocks (SBBs) and RACH configuration information about RACH resources and transmitting a RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information about actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources by a positive integer multiple of the number of the actually transmitted SSBs in a RACH configuration period based on the RACH configuration information.

Abstract: A base station receives uplink data and a first demodulation reference signal (DMRS) in a physical multiple access (MA) resource, and attempts to decode the uplink data, using the first DMRS. When the base station fails to decode the uplink data, the base station transmits an ACK/NACK for a first MA signature corresponding to the first DMRS among multiple MA signatures. When the ACK/NACK for the first MA signature is a NACK and the received power level of the first DMRS is higher than or equal to a threshold, the base station transmits a MA signature reselection command for the first MA signature together with the ACK/NACK. When the ACK/NACK for the first MA signature is a NACK and the received power level of the first DMRS is lower than the threshold, the base station transmits a MA signature maintenance command for the first MA signature together with the ACK/NACK.
