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

The second wireless device 200 may include one or more processors 202 and one or more memories 204 and additionally further include one or more transceivers 206 and/or one or more antennas 208. The processor 202 may control the memory 204 and/or the transceiver 206 and may be configured to implement descriptions, functions, procedures, proposals, methods, and/or operation flows disclosed in the present disclosure. For example, the processor 202 may process information in the memory 204 and generate a third information/signal and then transmit a radio signal including the third information/signal through the transceiver 206. Further, the processor 202 may receive a radio signal including a fourth information/signal through the transceiver 206 and then store in the memory 204 information obtained from signal processing of the fourth information/signal. The memory 204 may connected to the processor 202 and store various information related to an operation of the processor 202. For example, the memory 204 may store a software code including instructions for performing some or all of processes controlled by the processor 202 or performing the descriptions, functions, procedures, proposals, methods, and/or operation flowcharts disclosed in the present disclosure. Here, the processor 202 and the memory 204 may be a part of a communication modem/circuit/chip designated to implement the wireless communication technology (e.g., LTE and NR). The transceiver 206 may be connected to the processor 202 and may transmit and/or receive the radio signals through one or more antennas 208. The transceiver 206 may include a transmitter and/or a receiver and the transceiver 206 may be mixed with the RF unit. In the present disclosure, the wireless device may mean the communication modem/circuit/chip.
