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.

Since SCI_pair shares the same SD beam as SCI, it is highly likely that it includes many LC coefficients that affect CSI accuracy. Therefore, if the row corresponding to SCI and the row corresponding to SCI_pair are mapped to the 0th and 1st indexes and given a priority level, it may be effective in reducing the loss of CSI accuracy while performing the UCI omission. An SD permutation embodiment for this may be expressed as Perm2(l)=A1 using
That is, in the above embodiment, it may be expressed as
