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.

Abstract: Disclosed is a method of transmitting a physical uplink control channel (PUCCH) by a user equipment (UE) in a wireless communication system. The method includes receiving information related to an index of a PUCCH resource set for the PUCCH and to the number of resource blocks (RBs) for the PUCCH, and transmitting the PUCCH through a PUCCH resource based on a first RB offset. A second RB offset of the PUCCH resource set is obtained based on the index, and the first RB offset is obtained by multiplying the number of RBs by the second RB offset.

Abstract: A UE performs PDCCH monitoring for at least one serving cell by switching a search space set of a first SSSG to a search space of a second SSSG at a search space set group (SSSG) switching time. When PDCCH monitoring is performed in a unit of a slot-group for the at least one serving cell, the UE determines the SSSG switching time based on a largest Xs value among Xs values for the at least one serving cell.
