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: Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.

Abstract: The present specification provides a method whereby a terminal receives a preconfigured uplink resource from a base station, and a device for same. In particular, the method whereby a terminal receives a preconfigured uplink resource from a base station comprises: receiving a preconfigured uplink (UL) resource (PUR) configuration through RRC signaling from the base station; and if the terminal is in idle mode, transmitting uplink data to the base station by using a preconfigured uplink resource, wherein the preconfigured uplink resource comprises 12 subcarriers, the uplink data comprises a de-modulated reference signal (DMRS) sequence having a first length and including six subcarriers, and the de-modulated reference signal sequence may be transmitted using six of the 12 subcarriers.
