Classification: CPC H | IPC H

Claim 10:
11. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
receive, from a base station, first information on first uplink resources for a first message of a 2-step random access procedure, second information on second uplink resources for the first message of the 2-step random access procedure, third information on a threshold size to determine the first uplink resources or the second uplink resources for the first message of the 2-step random access procedure, and fourth information on a reference signal received power (RSRP) threshold for selection between the 2-step random access procedure and a 4-step random access procedure,
select a random access type as the 2-step random access procedure based on an RSRP for downlink being above the RSRP threshold,
identify whether a size of information to be included in the first message is greater than the threshold size based on the 2-step random access procedure being selected,
in case that the size of the information is greater than the threshold size, select a resource from the first uplink resources,
in case that the size of the information is not greater than the threshold size, select the resource from the second uplink resources, and
transmit, to the base station, the first message of the 2-step random access procedure using a resource from the selected uplink resources.
