1. A method performed by a user equipment (UE) for a random access procedure in a wireless communication system, the method comprising:
receiving a system information block (SIB) from a base station, wherein the SIB includes time division duplex (TDD) uplink-downlink configuration information for a serving cell of the UE and information on uplink subcarrier spacing (SCS) supported in the serving cell;
transmitting a first message to the base station based on the TDD uplink-downlink configuration information and the uplink SCS of the SIB, the first message being a random access preamble;
receiving a second message from the base station, the second message being a response to the first message; and
transmitting a third message to the base station using a carrier different from a carrier used to transmit the first message,
wherein the uplink SCS of the serving cell is determined depending on the TDD uplink-downlink configuration information of the serving cell, and
wherein i) payload size of scheduling information for resource allocation of the third message in the second message and ii) the number of subcarriers used for transmitting the third message are determined based on the uplink SCS.
