    Abstract: A method and apparatus for adjusting the transmission power of signals transferred by at least one home base station through a wireless interface to a mobile device, the at least one home base station being located in the cell of a base station. The transmission power is adjusted by first performing an inter cell interference coordination procedure including determining at least one high interference reference zone for the at least one home base station. Then the signal transmission power adjustment for the at least one home base station is determined to ensure a given outage probability that a given function g representing the mobile terminal performance degradation is lower than or equal to a threshold value in the high interference reference zone around the at least one home base station.

  • Patent number: 8781488
    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.
