Claim 5:
6. A method performed by a base station in a communication system, the method comprising:
transmitting, to a terminal, 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; and
receiving, from the terminal, a PUSCH on a valid PUSCH occasion,
wherein a number of N preamble indexes of valid PRACH occasions are mapped to the valid PUSCH occasion and an associated demodulation reference signal DMRS resource, and
wherein N is the number of preamble indexes mapped to the valid PUSCH occasion and 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.
