1. A method of reporting channel state information (CSI) through physical uplink shared channel (PUSCH), by a user equipment (UE), in a wireless communication system, the method comprising:
receiving, from a base station, configuration information,
wherein the configuration information includes (i) a CSI related configuration and (ii) a configuration related to transmission power control of the PUSCH;
receiving, from the base station, a CSI-reference signal (CSI-RS) based on the CSI related configuration;
obtaining CSI based on the CSI-RS,
wherein the CSI includes information related to coefficients,
wherein each of elements of the information related to the coefficients is classified as a plurality of groups based on a priority value,
wherein the priority value is determined based on i) a layer index, ii) an index of a spatial domain related to each of the element and iii) an index of a frequency domain related to each of the elements, and
wherein the priority value increases 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
transmitting, to the base station, a CSI report configured by omitting, among the plurality of groups, a portion of the plurality of groups based on a pre-defined priority of the plurality of groups, through the PUSCH,
wherein a transmission power of the PUSCH is determined based on the configuration information.
