Abstract: A telecommunication network includes a telecommunication device and one or more mobile terminals that communicate data over multiple frequency bands. The telecommunication device obtains the carrier aggregation capability of the mobile terminals, as well as its own coordinated carrier aggregation capability. The telecommunication device then transfers this information to a centralizing device, as well as information related to a neighboring telecommunication device. The centralizing device then responds with a frequency band to be used by the telecommunication device for communication with the mobile terminals, as well as control signaling through the frequency band.
