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.

說明書

For example, the priority value may increase in an order in which a higher index and a lower index of the indexes of the frequency domain associated with/related to the components are sequentially crossed based on a predefined specific index. The predefined specific index may be associated with/related to an index in the frequency domain of a strongest coefficient among the coefficients. For example, the predefined specific index may be ‘0’. As another example, the priority value may increase in an ascending order of the index of the spatial region.

For example, the operation of the base station (100/200 in FIGS. 15 to 19) of the above-described step S1440 receiving the CSI from 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 receive the CSI, and one or more transceivers 206 may receive the CSI from the UE.

In addition, the UE and/or the base station operating according to each step of the above-described methods and embodiments (e.g., proposal 1/proposal 2, etc.), FIG. 12, 13 or 14, etc., may be specifically implemented by the device in FIGS. 15 to 19. For example, the base station may correspond to a first radio device, the UE may correspond to a second radio device, and vice versa may be considered in some cases.
