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

FIG. 13 illustrates an example of an operation flowchart of a UE to which the method and/or embodiment proposed in the present disclosure may be applied. FIG. 13 is only for convenience of description, and does not limit the scope of the present disclosure. Referring to FIG. 13, it is assumed that the UE and/or the base station operate based on the methods and/or embodiments of the above-described proposals 1 and 2. Some of the steps described in FIG. 13 may be merged or omitted. In addition, in performing the procedures described below, the CSI-related operation of FIG. 7 may be considered/applied.

The UE may receive the configuration information including the BWP configuration related to the bandwidth part (BWP) from the base station (S1310). For example, the BWP configuration may include information such as a cyclic prefix related to the BWP, a location of a frequency domain, and a subcarrier interval. For example, on or more BWPs may be configured based on the BWP configuration information. For example, the BWP configuration information may be received through higher layer signaling (e.g., RRC).
