摘要： The present disclosure provides a method of receiving a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system. The method may include: receiving (i) a first parameter related to a bandwidth part (BWP) and (ii) a second parameter related to a plurality of search space (SS) sets included in the BWP through higher layers; monitoring only a specific SS set among the plurality of SS sets; based on that a first PDCCH is received in the specific SS set, monitoring all of the plurality of SS sets; and receiving a second PDCCH in one SS set among the plurality of SS sets. Based on that the one SS set is the specific SS set, monitoring of other SS sets except for the specific SS set among the plurality of SS sets may be terminated.

摘要： 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.
