Abstract: Disclosed are a method for transmitting and receiving downlink signals between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting same. More specifically, as one applicable embodiment in the present disclosure, the terminal can control/change a monitoring period of a physical downlink control channel on the basis of whether a downlink signal transmission burst is transmitted from a base station, and in response thereto, the base station sets a transmission period of the physical downlink control channel in the downlink signal transmission burst so as to transmit the same to the terminal.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: The present invention discloses a method for a terminal to receive a synchronization signal in a wireless communication system. Particularly, the method includes the steps of receiving a synchronization block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH) and receiving a DMRS (demodulation reference signal) via resource region in which the PBCH is received. In this case, an index of the synchronization block can be determined in consideration of a sequence of the DMRS.

Abstract: A method of transmitting and receiving a random access channel is proposed. In particular, the method includes receiving information on a specific bandwidth for transmitting a RACH preamble and information on the number of RACH frequency resources allocated in the specific bandwidth, and transmitting the RACH preamble over at least one RACH frequency resource among a plurality of RACH frequency resources allocated by the number of the RACH frequency resources in the specific bandwidth, wherein the specific bandwidth is configured as a portion of an entire system bandwidth.

Abstract: A user equipment in a wireless communication system receives RACH configuration information including preamble format information indicating a first format and transmits a RACH preamble with the first format. The RACH preamble with the first format includes a cyclic prefix (CP) part and a sequence part in a time domain. The RACH preamble with the first format satisfies: a CP length of the RACH preamble of the first format is N times a CP length NCP of an orthogonal frequency division multiplexing (OFDM) symbol, where N is the number of OFDM symbols used to transmit a RACH preamble and is greater than 1.
