PROBLEM TO BE SOLVED: To provide a technique for reducing overhead system information between nodes and user equipment (UE).SOLUTION: Among the carriers, it is beneficial to have some special carriers designated by configurations in order to provide synchronization, system information, paging, data and control for multi-carrier enabled UE. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UE for access, synchronization, broadcast, and new control region within data regions of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages. |
