The disclosed subject matter relates to an architecture that can leverage Universal Mobile Telecommunication System (UMTS) Terrestrial Radio Access Network (UTRAN) features to facilitate more efficient or more robust communication with a femtocell network. In particular, features such as a UMTS localized common pilot channel along with various UTRAN features can enable communications to be directed to specific targets such as to a specific home nodeB (HNB) or to a specific mobile device served by the HNB, while also reducing macro network load.
