1. A method of transmitting and receiving a signal by a user equipment (UE) operating in a wireless communication system, the method comprising:
transmitting a physical random access channel (PRACH); and
receiving a random access response (RAR) based on the PRACH,
wherein the PRACH is transmitted in one or two PRACH slots,
wherein the one or two PRACH slots are determined among N slots corresponding to a reference slot,
wherein, based on one of 480 kHz subcarrier spacing (SCS) and 960 kHz SCS being used for the N slots, 60 kHz SCS is used for the reference slot,
wherein a number of PRACH slots in the reference slot is 1, a value for the one PRACH slot is N-1,
wherein the number of PRACH slots in the reference slot is 2, values for the two PRACH slots are N/2−1 and N-1, and
wherein the N is 8 for the 480 kHz SCS and the N is 16 for the 960 kHz SCS.
