Patent ID: 11838952

Abstract:
The present invention relates to a method for performing a random access procedure in a wireless communication system and a device therefor, the method comprising a step for receiving NPRACH configuration information and a step for transmitting a random access preamble on the basis of the NPRACH configuration information, wherein the NPRACH configuration information includes information indicating whether only a first preamble format is supported, only a second preamble format is supported, or both the first preamble format and the second preamble format are supported. If both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the first preamble format, and, if both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the second preamble format.
