Abstract
The invention relates to a method for reporting channel state information from a user equipment (UE) to a eNodeB. In particular, the channel state information report is generated for all component carriers configured by the UE, independent from whether channel state information was actually calculated or not. If no channel state information is calculated for a specific component carrier, then the channel state information encodes information as to the status of said specific component carrier and thus the reason why no channel state information calculation was performed. For instance, the channel state information may encode that the status of the component carrier is deactivated, allowing the base station to check whether a component carrier is indeed activated or deactivated at the UE side.
