Abstract: A method of performing, by a user equipment (UE), a random access procedure in a wireless communication system is disclosed. The method includes receiving configuration information related to the random access procedure, transmitting a random access preamble and a physical uplink shared channel (PUSCH), and receiving a random access response (RAR) message. The PUSCH is transmitted based on a predetermined PUSCH transmission power. The predetermined PUSCH transmission power is based on preamble reception power information related to a transmission of the random access preamble and a specific offset.

Abstract: Provided are a method of performing a channel access procedure by an apparatus in an unlicensed band, and an apparatus using same method. The apparatus determines a contention window size (CWS) and performs a channel access procedure with respect to a first channel on the basis of the determined contention window size. The contention window size may be adjusted on the basis of feedback information relating to a second channel. When a transmission history of the second channel, which is to be reflected in determining the contention window size, does not exist, the contention window size may be determined to be a minimum CWS value in a specific channel access priority class.
