Abstract: A user equipment (UE) in a wireless communication system receives configuration information for random access channel (RACH) resources. The UE transmits a first preamble of a random access procedure using a first RACH resource among the RACH resources based on the configuration information, and monitors a RAR message of the random access procedure based on a first random access radio network temporary identifier (RA-RNTI). In the present invention, the first RA-RNTI is computed based on an index of a time unit of the first RACH resource and an index of the first symbol of the first RACH resource, where each time unit consists of 14 symbols in a time domain, and the index of the first symbol of the first RACH resource is a non-negative integer value smaller than 14.
