Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: The present invention relates to a method and a device for a New Radio (NR) access technology base station transmitting a signal in a wireless communication system. Specifically, the method comprises the steps of: checking a configuration associated with a subframe assigned to a Long Term Evolution (LTE) band; according to the checked configuration, determining a resource region in which a NR downlink signal may be assigned in the LTE band in a specific subframe shared for NR communication; and transmitting a control resource set (CORSET) via the resource region. The NR UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

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 and a specific condition is met, 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 and the specific condition is not met, the random access preamble is transmitted using the second preamble format.
