Abstract  Abstract

This invention relates to a method (and a corresponding communication apparatus) for reporting to an eNodeB a power headroom for a non-scheduled uplink component carrier the method comprising the following steps performed by a user equipment:
receiving resource assignment information for allocating an uplink resource or a downlink resource to the user equipment the resource assignment information including a plurality of bits wherein each of a plurality of component carriers corresponds to one bit of the plurality of bits the one bit indicating whether a corresponding component carrier is to be activated or deactivated and wherein when any one bit of the plurality of bits indicates that its corresponding component carrier is to be activated the plurality of bits further indicate a request for a power headroom report;
calculating a power headroom for a scheduled uplink component carrier based on the received resource assignment information;
calculating a virtual power headroom for a non-scheduled uplink component carrier based on a pre-configured virtual uplink resource assignment for the non-scheduled uplink component carrier; and
transmitting to the eNodeB the calculated power headroom for the scheduled uplink component carrier and the calculated virtual power headroom for the non-scheduled uplink component carrier using an activated component carrier.
