Abstract: The present invention relates to a method and an apparatus for generating a signal for low latency in a wireless communication system. The method, according to one embodiment of the present invention, for a communication device generating a situation-reporting signal for low latency and transmitting the signal to a base station in a wireless communication system comprises the steps of: generating the situation-reporting signal on the basis of a pre-set, specific situation recognized by the communication device; and transmitting the generated situation-reporting signal to the base station, wherein the situation-reporting signal may be generated so as to have a subcarrier spacing which is a pre-set number of times larger than a subcarrier spacing of a legacy communication system, the pre-set number being an integer.

Abstract: According to one embodiment of the present disclosure, a method and an apparatus for allowing a user equipment (UE) to effectively monitor a control resource set (CORESET) in order to read remaining minimum system information (RMSI) in a wireless communication system are provided. The UE receives a media access control (MAC) control element (CE) indication, performs a random access channel (RACH) procedure, determines a transmission configuration indicator (TCI) state of CORESET 0 on the basis of the most recent of either the MAC CE indication or the RACH procedure, and monitors CORESET 0 on the basis of the determined TCI state.

Abstract: A user equipment of the present invention generates a preamble sequence, which includes a base sequence N number of times. The user equipment maps, by comb-type, the base sequence in a frequency domain, and maps the base sequence to one of N kinds of frequency locations, thereby generating the preamble sequence. The user equipment transmits a random access preamble including the preamble sequence.

Abstract: A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.
