Abstract
A femtocell basestation selects its carrier frequency by detecting a carrier used by at least one other basestation in its network, and selecting its own carrier frequency such that it partially overlaps with the detected carrier. The downlink power of the femtocell basestation is set based on the degree of overlap between the selected carrier and the detected carrier, so that a user equipment having a connection to the other basestation is forced to search for the selected carrier.

1-12. (canceled)
A method of operation of a basestation in a cellular communications network, the method comprising, in the basestation:
- detecting signals transmitted by other basestations of the cellular communications network;
- identifying carrier frequencies on which the detected signals are being transmitted by the other basestations;
- and
- selecting a carrier for transmissions from the basestation, wherein the carrier selected for transmissions from the basestation has a bandwidth that partially overlaps with the carrier frequencies on which the detected signals are being transmitted by the other basestations.
A basestation, for use in a cellular mobile communications network, wherein the cellular mobile communications network comprises a plurality of other basestations, each transmitting signals on respective carrier frequencies, and wherein the basestation is adapted to operate in accordance with the method according to any preceding claim.
