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: 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 method of receiving, by a user equipment (UE), a physical downlink shared channel (PDSCH) in a wireless communication system is disclosed. The method comprises receiving configuration information related to the PDSCH, receiving a message representing an activation of a transmission configuration indicator (TCI) state related to the PDSCH, receiving physical downlink control information (DCI) scheduling the PDSCH, and receiving the PDSCH based on the DCI. Specific frequency domains related to the activation are determined based on the message, and the activated TCI states are related to the specific frequency domains.

Abstract: Disclosed herein are a method and a device for transmitting a message in an initial access procedure by a user equipment (UE) in a wireless communication system. According to the present disclosure, a UE may transmit to a base station capability information associated with transmission power of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive first control information for transmitting a message associated with an initial access and the control information may include a TPMI used for the UE to transmit the message. Thereafter, the UE may transmit to the base station the message by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.
