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

Embodiments of the present disclosure can be implemented by various means, for example, hardware, firmware, software, or combinations thereof. When embodiments are implemented by hardware, one embodiment of the present disclosure can be implemented by one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, microcontrollers, microprocessors, and the like.

When embodiments are implemented by firmware or software, one embodiment of the present disclosure can be implemented by modules, procedures, functions, etc. performing functions or operations described above. Software code can be stored in a memory and can be driven by a processor. The memory is provided inside or outside the processor and can exchange data with the processor by various well-known means.

It is apparent to those skilled in the art that the present disclosure can be embodied in other specific forms without departing from essential features of the present disclosure. Accordingly, the aforementioned detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the present disclosure should be determined by rational construing of the appended claims, and all modifications within an equivalent scope of the present disclosure are included in the scope of the present disclosure.

INDUSTRIAL APPLICABILITY

The method for mapping channel state information in a wireless communication system of the present disclosure has been described focusing on examples applied to the 3GPP LTE/LTE-A system and 5G system (New RAT system), but can be applied to various wireless communication systems.
