Abstract: A UE transmits a random access channel (RACH) preamble and a BS receives the RACH channel. The BS configures the RACH preamble to align boundaries of the RACH preamble with boundaries of OFDM symbols on which the RACH preamble is configured in the time domain. The UE generates/transmits the RACH preamble to align the boundaries of the RACH preamble with the boundaries of OFDM symbols on which the RACH preamble is configured in the time domain.

Abstract: A method by which a terminal measures channel state information (CSI) in an unlicensed band is disclosed. Particularly, the method comprises: receiving at least one channel state information-reference signal (CSI-RS) through at least one listen before talk (LBT) sub-band of a plurality of LBT sub-bands for transmitting a plurality of CSI-RSs within one transmit opportunity (TxOP) section; determining each measurement use for at least one CSI-RS; and measuring the CSI on the basis of each measurement use for the at least one determined CSI-RS, wherein the determination of each measurement use for the at least one CSI-RS is the determining of whether the CSI-RS is for an interference measurement or the CSI-RS is for a signal measurement.

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.

Abstract: According to one embodiment, a distance technique between a transmitter and a receiver for processing a signal in symbol units is presented. According to the embodiment, the transmitter transmits a transmission signal to the receiver through preset first and second frequencies. Then, the transmitter receives, from the receiver, a reception signal corresponding to the transmission signal. The reception signal includes a first reception component corresponding to the first frequency and a second reception component corresponding to the second frequency. The phase difference set by the receiver is applied between the phase of the first reception component and the phase of the second reception component. The phase difference is set on the basis of the difference between a reception time at which the transmission signal is received by the receiver and a processing time at which the transmission signal is processed in the receiver.
