1. A method of performing a random access procedure by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, configuration information related to the random access procedure;
transmitting, to the base station, a first message including (i) a Physical Random Access Channel (PRACH) preamble and (ii) a Physical Uplink Shared Channel (PUSCH) related to random access, based on the configuration information; and
receiving, from the base station, a random access response message in response to the first message including (i) the PRACH preamble and (ii) the PUSCH related to random access,
wherein the PUSCH related to random access is associated with a Demodulation Reference Signal (DMRS) resource related to a scrambling identifier (ID),
wherein the configuration information includes (i) time domain offset information providing an offset between (i) a first resource region for the PUSCH related to random access and (ii) a second resource region for the PRACH preamble and (ii) resource information for the first resource region for the PUSCH related to random access,
wherein the first resource region for the PUSCH related to random access is determined in the time domain based on the offset from a start of a time unit including (i) the first resource region for the PUSCH related to random access and (ii) the second resource region for the PRACH preamble, and
wherein based on the offset, the PUSCH related to random access on the first resource is transmitted (i) after the PRACH preamble on the second resource region is transmitted by the UE and (ii) before the random access response message is received by the UE.
