Claim 0:
1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, information associated with a physical random access channel (PRACH) and a physical uplink shared channel (PUSCH) resource for a 2-step random access type procedure;
mapping a number of N preamble indexes of valid PRACH occasions to a valid PUSCH occasion and an associated demodulation reference signal (DMRS) resource; and
transmitting, to the base station, a PUSCH on the valid PUSCH occasion,
wherein N is the number of preamble indexes mapped to the valid PUSCH occasion and the associated DMRS resource and determined based on:
a total number of valid PRACH occasions per association pattern period multiplied by a number of preambles per valid PRACH occasion, and
a total number of valid PUSCH occasions per PUSCH configuration per association pattern period multiplied by a number of DMRS resource indexes per valid PUSCH occasion.
