Original Abstract Submitted

In accordance with an example embodiment of the present invention, provided are methods, apparatuses and computer program products configured at least to: select an integer number NO of channel state information reference signal (CSI-RS) resources out of an integer number of NTRP network configured CSI-RS resources to a resource set associated with a CSI report configuration, wherein N<N; determine a scaling factor for the resource set; determine at least one CSI component, based at least in part on an assumption that a ratio of a transmitted energy per resource element (EPRE) of a PDSCH signal and a transmitted EPRE of the nCSI-RS resource is equal to the scaling factor times a power control offset configured for the nCSI-RS resource of the resource set, wherein n ϵ [1, N]; and transmit a CSI report to a network comprising the determined at least one CSI component.
