Title: METHOD FOR PERFORMING RANDOM ACCESS PROCEDURE FOR SINGLE TONE TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Abstract:
Disclosed in the present application is a method for performing, at a terminal, a random access procedure for narrow band communication in a wireless communication system. Specifically, the method comprises the steps of: receiving information on a starting subcarrier index for a random access channel; allocating a frequency resource to the random access channel in a subcarrier index order from the starting subcarrier index by a predetermined number of subcarriers in one resource block; and transmitting the random access channel to a base station using the allocated frequency resource, wherein the step of allocating the frequency resource comprises a step of allocating the remaining frequency resources to the random access channel in the subcarrier index order from a specific subcarrier in the one resource block if a subcarrier index to be allocated is larger than a maximum subcarrier index in the one resource block.
