METHODS AND APPARATUS FOR RESOURCE MANAGEMENT IN A MULTI-CARRIER TELECOMMUNICATIONS SYSTEM
First Claim
1. A method in a radio base station, for resource management in a multi-carrier system comprising a cell served by the radio base station and wherein a plurality of component carriers (CCs) are defined for said cell, the method comprising:
- assembling a message comprising information on a structure of the cell, said information including at least one CC used in the cell that is available for a user equipment (UE), for performing initial access in the cell.transmitting said message to the UE; and
indicating to said UE to what at least one resource the UE is to use for random access in the cell.

Abstract
The embodiments of the present invention relate to apparatuses and methods for resource management in a multi-carrier system wherein a plurality of component carriers (CCs) is defined per cell. According to a method in an apparatus corresponding to a radio base station, a message is assembled comprising information on the structure of the cell served by the radio base station; the information including one or more CCs used in the cell that is/are available for a user equipment for performing initial access in the cell. The method also comprises, transmitting the assembled message to the user equipment and indicating to the user equipment to what resources to use for random access in the cell. The exemplary embodiments of the present invention also relates to a method in the user equipment, to a radio base station and to a user equipment.
