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.

Abstract: The present disclosure discloses a method of receiving a synchronization signal block by a user equipment (UE) in a wireless communication system. The method includes receiving, in one of two half frames included in a frame, a synchronization signal block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), and receiving a demodulation reference signal (DMRS) in a resource region carrying the PBCH. Information about the half frame in which the synchronization signal block is received may be obtained from a sequence of the DMRS.

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: Disclosed are a method for transmitting and receiving channel state information in wireless communication system and an apparatus therefor. Specifically, a method for transmitting, by a user equipment (UE), Channel State Information (CSI) in a wireless communication system may include: receiving, from a base station, a channel state information reference signal (CSI-RS) through multiple antenna ports; and reporting, to the base station, CSI, in which the CSI may include selection information indicating a plurality of codewords used for generating a precoding matrix in a codebook for reporting the CSI, and a power coefficient, a phase offset, and a phase shift value applied to each of the plurality of codewords in terms of a configured bandwidth, and the precoding matrix may be generated in units of subbands within the configured bandwidth based on a linear combination of the power coefficient, the phase offset, and the phase change value.

Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.
