Abstract: Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.

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: 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: Disclosed herein is a method for reporting channel state information (CSI) of a terminal in a wireless communication system. The method includes: measuring a CSI-RS (reference signal) transmitted from a base station through multiple panels; and reporting CSI generated based on the CSI-RS measurement to the base station, wherein, when the terminal reports a WB (Wideband) panel corrector and SB (Subband) panel corrector for the multiple panels as the CSI, the WB panel corrector and the SB panel corrector are reported with different bit widths.
