Method and an apparatus for enabling at least one mobile terminal to transfer and/or receive data through multiple frequency bands

Method for determining which frequency bands have to be used, in a wireless cellular telecommunication network, to communicate with at least one mobile terminal, the at least one mobile terminal being served by a telecommunication device which is able to communicate with the at least one mobile terminal through at least one frequency band, wherein the method comprises the steps, executed by a centralizing device of the wireless cellular telecommunication network, of:

• receiving from the telecommunication device, a coordinated mobile terminal carrier aggregation capability C of the telecommunication device,
• receiving from the telecommunication device, information related to at least one neighbouring telecommunication device of the telecommunication device,
• determining for the telecommunication device and the at least one neighbouring telecommunication device, the at least one frequency band the telecommunication device has to use for communicating with the at least one mobile terminal and the at least one frequency band the at least one neighbouring telecommunication device has to use for communicating with the at least one mobile terminal or another mobile terminal,
• transferring to the telecommunication device, information indicating to the telecommunication device, the at least one frequency band the telecommunication device has to use for communicating with the at least one mobile terminal.
