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.
