1. A method performed by a user equipment in a wireless communication system, the method comprising:
obtaining, from a higher layer signaling, an indication to perform a random access procedure;
transmitting a random access signal including a physical random access channel (PRACH) preamble and a data part to a base station in a transmission interval; and
receiving, from the base station, a random access response (RAR) signal including a timing advance (TA) command in response to the random access signal; and
based on the RAR signal including a contention resolution identity: transmitting, to the base station, a physical uplink control channel (PUCCH) including hybrid automatic repeat request-acknowledge (HARQ-ACK) information; and
based on the RAR signal including an uplink grant: transmitting, to the base station, a physical uplink shared channel (PUSCH),
wherein a beam direction for the PRACH preamble and a beam direction for the data part are equal to each other, and
wherein a TA value of the PRACH preamble is configured to zero and a TA value of the data part is configured to zero.
