Abstract: Performing a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, a method may include: transmitting message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein a power ramping counter is used to configure transmission power of message A, and the power ramping counter has a value which increases based on that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.

Abstract: A UE can perform first uplink transmission on the basis of a first scheduling message without NDI, receive a second scheduling message including an NDI field, and perform i) retransmission for the first uplink transmission or ii) new uplink transmission on the basis of the NDI field in the second scheduling message. Performing the retransmission for the first uplink transmission or the new uplink transmission can comprise: determining, in a state in which an NDI value for the first scheduling message is considered a specific value, whether the value of the NDI field is toggled in comparison to the specific value; performing the retransmission for the first uplink transmission on the basis of the non-toggling of the value of the NDI field in comparison to the specific value; and performing the new uplink transmission on the basis of the toggling of the value of the NDI field in comparison to the specific value.

Abstract: Disclosed are a method for transmitting and receiving a synchronization signal in a wireless communication system and an apparatus therefor. Specifically, a method for performing synchronization signal by transmitting and receiving a synchronization signal includes: receiving, from a base station, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); and performing synchronization by using the received PSS and the received SSS, in which a sequence for the SSS may be generated by a product between a first sequence and a second sequence and the number of first sequences may be configured to be larger than the number of second sequences.

Abstract: Disclosed herein is a method for transmitting a physical random access channel (PRACH) by a user equipment in a wireless communication system. In particular, the method includes receiving information about PRACH resource allocation, and transmitting, based on the information, the PRACH on any one of one or more PRACH occasions allocated in a PRACH slot, wherein a number of the one or more PRACH occasions is based on a preamble format and a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol for the PRACH.
