Method for reporting channel state information in wireless communication system, and device for same
摘要
說明書
In the above scheme, when the UE wants to report CSI to the base station, if the corresponding PUSCH resource capacity does not satisfy the CSI payload, some or all of the UCI part 2 components of the CSI are dropped to allow the UE to transmit the channel information to the base station within the available resource capacity range. In addition, whether the UE configures UCI by performing the CSI omission may be indicated to the base station.
As described above, the UCI part 2 may include information such as a bitmap per layer, an SD/FD basis indicator, LC coefficients per layer (amplitude/phase), and SCI per layer (the strongest coefficient indicator). For example, the information on the LC coefficients may include an indicator indicating amplitude coefficients and an indicator indicating phase coefficients. Also, the bitmap information for each layer may be bitmap information for indicating an indicator indicating reported amplitude coefficients and an indicator indicating phase coefficients. In this case, the information on the LC coefficients (amplitude coefficient/phase coefficient) and the bitmap information corresponding thereto may have the greatest influence on the payload size among the components. Therefore, it is necessary to specify an omission method for these parameters (components) (e.g., amplitude coefficient, phase coefficient, bitmap, etc.), and the omission method can be configured by utilizing SCI for each layer.
