Abstract
The UE receives a CSI reporting configuration containing multiple subconfigurations and determines a basis for the power control coefficient. The UE determines a power control coefficient for one of the subconfigurations based at least partially on the power control coefficient basis. The UE sends a CSI report associated with the subconfiguration to the network. This CSI report contains one or more CSI quantities. At least one of the one or more CSI quantities is determined based on the power control coefficient for the subconfiguration. Network elements send a CSI reporting configuration containing multiple subconfigurations to the UE and receive a CSI report associated with one of the subconfigurations. The CSI report contains one or more CSI quantities determined based on the power control coefficient for the subconfiguration. Network elements determine a spatial pattern based on the received CSI report.
