    Abstract: Disclosed in the present invention are a method for performing uplink transmission in a wireless communication system and a device for same. Specifically, a method, by which a user equipment (UE) transmits a sounding reference signal (SRS) in a wireless communication system, may include: a step for receiving setting information related to the transmission of the SRS; and a step for transmitting the uplink control channel on the basis of the setting information, wherein the setting information includes settings indicating at least one of i) a transmission unit or ii) a beam related to the transmission of the SRS. The transmission unit and the beam may be determined on the basis of i) an uplink reference signal transmitted by the UE or ii) a downlink reference signal received by the UE.

    Abstract: A method of transmitting channel state information (CSI) in a wireless communication system includes: receiving, from a base station, configuration information related to CSI; receiving, from the base station, a CSI-reference signal (CSI-RS) on a plurality of CSI-RS resources; and transmitting, to the base station, first CSI based on the configuration information. The plurality of CSI-RS resources corresponding to the configuration information are configured with (i) one or more channel measurement resources (CMRs) configured to be used to derive CSI based on a single CMR and (ii) one or more CMR pairs configured to be used to derive CSI based on a single CMR pair, unless there is a specific configuration by the configuration information, based on the first CSI being CSI derived based on a single CMR, any CMR included in the one or more CMR pairs may be not used to derive the first CSI.

    Abstract: Systems and techniques for transmitting channel state information (CSI) include: receiving configuration information related to the CSI from a base station, the configuration information including information on a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI to the base station based on the configuration information and the CSI-RS. The CSI-RS resource set includes M CSI-RS resource groups; in addition, N CSI-RS resource groups (N≤M) for reporting the CSI are determined from the M CSI-RS resource groups; the CSI includes N CSI sets generated based on a CSI-RS resource combination in the N CSI-RS resource groups. To generate an n-th (1≤n≤N) CSI set, a specific CSI-RS resource in an n-th (1≤n≤N) CSI-RS resource group is used for channel measurement; and a specific CSI-RS resource in the remaining CSI-RS groups other than the n-th CSI-RS resource group is used for interference measurement.

    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.
