1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
in case that a size of uplink data to be transmitted is less than or equal to a threshold value and a set of random access (RA) resources for early data transmission (EDT) is configured, transmitting to a base station, a message A including the uplink data, in a 2-step RA procedure; and
receiving, from the base station, a message B
including a UE contention resolution identifier (ID) and a physical uplink control channel (PUCCH) resource indicator for an acknowledgement (ACK) for the message B,
wherein the set of RA resources for the EDT is different from a set of RA resources for non-EDT.
