Abstract: A method of transmitting, by a user equipment (UE), an uplink channel in a wireless communication system comprises transmitting capability information related to a panel for a transmission of the uplink channel, receiving configuration information related to the transmission of the uplink channel, and transmitting the uplink channel based on the configuration information. Based on that the transmission of the uplink channel collides with a transmission of other uplink channel scheduled to the UE in a time domain, i) if a first panel related to the transmission of the uplink channel is different from a second panel related to the transmission of the other uplink channel, the uplink channel and the other uplink channel are simultaneously transmitted, and ii) if the first panel is the same as the second panel, the uplink channel is transmitted in a specific resource.

Abstract: A default subcarrier spacing for use in transmission/reception of a broadcast channel is defined for each frequency range. A base station transmits a broadcast channel in a frequency band, using the default subcarrier spacing defined for a frequency range to which the corresponding frequency band belongs. A user equipment attempts to detect a broadcast channel in the frequency band where a cell search is being attempted, using the default subcarrier spacing defined for a frequency range to which the frequency band belongs.

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: Proposed is a method for transmitting a physical random access channel (PRACH) preamble in a wireless communication system. Specifically, a method performed by user equipment (UE) comprises the steps of: receiving, from a base station, setting information including a first power ramping step for a two-step random access channel (RACH) and a second power ramping step for a four-step RACH; transmitting, to the base station, information including a first preamble and a physical uplink shared channel (PUSCH) for a two-step RACH on the basis of the first power ramping step; and transmitting, to the base station, a second preamble for a four-step RACH by using the second power ramping step, on the basis of the number of retransmissions of the information exceeding a maximum number of retransmissions associated with a preset two-step RACH.
