    Abstract: Disclosed are a method for reporting channel state information in a wireless communication system, and a device for same.
    Specifically, a method for a user equipment (UE) to report channel state information (CSI) in a wireless communication system includes: receiving bandwidth part (BWP) configuration information related to a BWP; receiving information for activating a specific bandwidth part among one or more bandwidth parts based on the BWP configuration information; receiving a reference signal; calculating CSI based on the reference signal; and transmitting the CSI by omitting a part of the CSI in the activated specific bandwidth part, based on a priority rule, wherein the CSI includes information related with coefficients, and each of elements of the information related to the coefficients is classified as a first group and a second group based on a priority value, wherein the priority value is determined as an order in which a higher index and a lower index of indexes of a frequency domain related to the elements are sequentially crossed based on a predefined specific index, and wherein a priority of the first group is defined as being higher than a priority of the second group in the priority rule.

    Abstract: The present disclosure provides a method for reporting channel state information (CSI) in a wireless communication system, and a device therefor. Specifically, the present invention provides a method for reporting CSI via a physical uplink shared channel (PUSCH) by a user equipment (UE) in a wireless communication system, the method comprising the steps of: receiving configuration information from a base station (BS), wherein the configuration information comprises (i) a CSI-related configuration and (ii) a configuration related to a transmission power control of the PUSCH; receiving a CSI-reference signal (CSI-RS) from the base station on the basis of the CSI-related configuration; calculating the CSI on the basis of the CSI-RS, wherein the CSI comprises information related with coefficients, elements of the information related with coefficients are classified into multiple groups on the basis of priority values thereof, and the priority values have an ascending sequence in which, with reference to a predefined particular index, a higher index and a lower index of frequency-domain indices related to the elements sequentially alternate; and on the basis of predetermined priorities of the multiple groups, transmitting a CSI report configured by omitting a portion of the multiple groups, to the base station via the PUSCH, wherein transmission power of the PUSCH is determined on the basis of the configuration information.

    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.
