In the present invention, a user equipment (UE) receives physical random access channel (PRACH) configuration information. The UE determines a part of PRACH resources among PRACH resources configured based on the PRACH configuration information, if a random access (RA) procedure is triggered. The UE performs the RA procedure using only the determined part of the PRACH resources. The PRACH configuration information includes a periodicity value N, expressed in number of configured PRACH resources. The determined part of PRACH resources are every N-th configured PRACH resource, starting from a specific PRACH resource for the RA procedure, among the PRACH resources configured based on the PRACH configuration information.
