摘要
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.

In Table 7, a density (D) represents a density of the CSI-RS resource measured in RE/port/physical resource block (PRB), and nrofPorts represents the number of antenna ports.
The UE reports the measured CSI to the BS (step S730).
Here, in the case that a quantity of CSI-ReportConfig of Table 7 is configured to ‘none (or No report)’, the UE may skip the report.
However, even in the case that the quantity is configured to ‘none (or No report)’, the UE may report the measured CSI to the BS.
The case where the quantity is configured to ‘none (or No report)’ is a case of triggering aperiodic TRS or a case where repetition is configured.
