The present disclosure relates to a method performed by a user equipment, UE, in a wireless communication system, the method comprising: receiving, from a base station, a system information block, SIB; transmitting, to the base station, a random access preamble for a random access procedure; receiving, from the base station, a random access response for the random access procedure; performing, to the base station, a physical uplink shared channel, PUSCH, transmission in the RACH procedure according to uplink resource allocation information included in the random access response, wherein application information of transform precoding for the PUSCH in the RACH procedure is identified based on the received SIB; receiving, from the base station, a radio resource control, RRC, setup message; entering into an RRC_CONNECTED state, based on the reception of the RRC setup message; and performing, to the base station, a PUSCH transmission, wherein application information of transform precoding for the PUSCH is identified based on the received SIB, in case that UE-specific application information of transform precoding for the PUSCH is not included in the RRC setup message.
