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.

For example, the operation of the base station (100/200 in FIGS. 15 to 19) of the above-described step S1410 transmitting the configuration information (e.g., BWP configuration information, CSI-related configuration information) to the UE (100/200 in FIGS. 15 to 19) may be implemented by the device in FIGS. 15 to 19 to be described below. For example, referring to FIG. 16, one or more processors 202 may control one or more transceivers 206 and/or one or more memories 204 or the like to transmit the configuration information, and one or more transceivers 206 may transmit the configuration information to the UE.

The base station may transmit activation information to the UE (S1420). For example, the activation information may be transmitted through MAC-CE or DCI. For example, the activation information may include information for activating a specific BWP among one or more BWPs. A specific BWP may be activated based on the activation information.
