METHOD FOR TRANSMITTING RANDOM ACCESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR METHOD

摘要

Disclosed is a method for transmitting a random access signal in a wireless communication system, the method carried out by a terminal according to the present specification comprising the step of transmitting a random access signal to a base station by means of a physical random access channel (PRACH) resource area of a narrow band (NB) having a system bandwidth of 180 kHz, wherein the PRACH resource area comprises a first PRACH resource area and a second PRACH resource area, each of which comprising at least one subcarrier having a particular subcarrier spacing, and any one from among the first PRACH resource area and second PRACH resource area is utilized for data transmission.
