Methods and apparatuses for resource management in a multi-carrier telecommunications system
First Claim
1. A radio base station operable in a multi-carrier system comprising a plurality of component carriers (CCs), comprising:
- a processing unit; and
a memory including computer program code, wherein the processing unit, the memory, and the computer program code are collectively configured to;
assemble a message including information on the plurality of CCs, of which only one CC is identified along with a dedicated preamble for a physical random access channel (PRACH) resource within the CC for random access within the multi-carrier system; and
provide the message and an indication of the PRACH resource to direct a user equipment to use the dedicated preamble for the PRACH resource within the CC to perform the random access within the multi-carrier system.

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.
