METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM

摘要

The present invention relates to a method and arrangement in a user equipment unit for activation of downlink component carriers. Even though configured to monitor multiple component carriers,a user equipment does not start to monitor them immediately but only one, or very few, carriers. Only if it decodes a DL assignment it will start to monitor multiple component carriers. After one, or possibly multiple, subframes where the UE is not scheduled anymore it falls back to its original state, i.e. it only monitors one (or very few) component carriers.
