Method for reporting channel state information in wireless communication system, and device for same
摘要
說明書
The UE may transmit the CSI to the base station (S1350). The CSI may be transmitted through a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). The reported CSI may include the first part and the second part. For example, the first part may correspond to the above-described uplink control information (UCI) part 1 (i.e., part 1 CSI), and the second part may correspond to UCI part 2 (i.e., part 2 CSI). For example, the CSI may be transmitted based on a specific BWP (e.g., active UL BWP) activated based on the activation information.
Based on the priority rule, some of the CSI may be omitted and transmitted. As an example, a part of the second part of CSI reporting may be omitted. Based on the above-described proposal methods (e.g., proposal 1, proposal 2, etc.), the omission of the second part of the CSI reporting may be performed. For example, each of the elements of the information related to the coefficients (e.g., information on the amplitude coefficient, information on the phase coefficient, bitmap information related to the amplitude coefficient and the phase coefficient) may be classified into a first group and a second group based on a priority value. In addition, the CSI reporting may be configured by the omission of the specific group according to the priority of the first group and the second group. For example, in the priority rule, the priority of the first group may be defined as higher than that of the second group. A group (e.g., second group) with a lower priority may be omitted first. As an example, a specific group to be included in the second part of the CSI reporting may be omitted.
