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.

Abstract: The present disclosure provides a method for reporting CSI in a wireless communication system. In the present disclosure, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: receiving, from an eNB, downlink control information (DCI) indicating activation of semi-persistent (SP) CSI reporting, in which the downlink control information is scrambled with a specific RNTI distinguished from a Cell-Radio Network Temporary Identity (C-RNTI); and reporting, to the eNB, the semi-persistent CSI through a physical uplink shared channel (PUSCH) based on the received downlink control information.

Abstract: Disclosed are a method for performing beam failure detection in a wireless communication system and an apparatus therefor. Specifically, a method for performing beam failure detection by means of a user equipment (UE) in a wireless communication system comprises the steps of: receiving a reference signal (RS) from a base station; determining whether a beam fails by measuring the reference signal; and transmitting, to the base station, the determination result on whether the beam fails, wherein by separating a case i) in which the base station does not transmit the reference signal from a case ii) in which the quality of the reference signal transmitted by the base station does not satisfy a specific threshold range, the step of determining whether the beam fails may be determined to be a beam failure only in the case ii).
