    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: 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.
