Abstract: The present invention discloses a method for a terminal to receive a synchronization signal in a wireless communication system. Particularly, the method includes the steps of receiving a synchronization block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH) and receiving a DMRS (demodulation reference signal) via resource region in which the PBCH is received. In this case, an index of the synchronization block can be determined in consideration of a sequence of the DMRS.

Abstract: Disclosed is a method for transmitting and receiving signals to enable a terminal to perform a random access channel procedure (RACH procedure) in an unlicensed band. In particular, the method comprises: transmitting an uplink signal including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving, from the base station, a downlink signal related to contention resolution in response to the uplink signal, wherein a power ramping counter is used to set the transmission power of the uplink signal, and the value of the power ramping counter may be increased on the basis of a transmission spatial beam for the transmission of the uplink signal being configured in the same manner as a transmission spatial beam for the transmission of a PRACH prior to the uplink signal.

Abstract: The present disclosure relates to a method of monitoring, by a wireless device, a downlink channel or a downlink signal. The method may include a step of receiving configuration information on a power save signal. The power saving signal can be used to signal that the downlink channel or the downlink signal should be monitored later. The configuration information may contain configuration information on an opportunity to omit the power saving signal. The method may include a step of monitoring the downlink channel or the downlink signal without monitoring the energy saving signal during the opportunity to omit. The length and/or position of the opportunity of omission can be determined according to the configuration information of a discontinuous receive cycle (DRX).

Abstract: Disclosed herein are a method and a device for transmitting and receiving uplink data in a wireless communication system. According to the present disclosure, a UE may transmit to a base station information related to a capability 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 Downlink Control Information (DCI) for transmitting the uplink data from the base station and the DCI may include a TPMI used for the UE to transmit the uplink data. Thereafter, the UE may transmit to the base station the uplink data 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.
