Abstract

The present disclosure relates to methods for reporting channel state information. The present disclosure also provides mobile stations for performing these methods, and computer readable media the instructions of which cause the mobile station to perform the methods described herein. For this purpose, the mobile station receives a trigger message that triggers the reporting of channel state information for at least one of the plurality of downlink component carriers, the trigger message being received in a subframe nTrigger, and reports the triggered channel state information for the at least one of the plurality of downlink component carriers based on reference signals present on the at least one of the plurality of downlink component carriers, in a subframe nReport later than nTrigger. The received trigger message indicates that the reference signals are present in a subframe nRS on the at least one of the plurality of downlink component carriers, where nTrigger≤nRS<nReport.
