Abstract

The embodiment of the present disclosure relates to methods and apparatuses for enhancing the reporting of the channel state information (CSI) with respect to multiple downlink resources. A method performed by a UE comprises: receiving, from a network node, a CSI report configuration which provides a number N of reference signal resources for channel measurement; performing measurements on said N RS resources; calculating or determining one or more CSI quantities for a number M of selected RS resources; and transmitting, to the network node, a CSI report including the calculated or determined CSI quantities, wherein the CSI report comprises two parts—part 1 and part 2—, and wherein the content contained in part 1 indicates the size of part 2. There is also disclosed a UE, a method performed in a network node and a network node.
