Systems, methods, devices, and computer program products are described for mitigating macrocell interference during femtocell discovery in a wireless communications system. In one example, a mobile device may be camped on a macrocell. A femtocell transmits out-of-band (OOB) discovery signals to, or receives OOB band discovery signals from, the mobile device to facilitate presence detection. The femtocell may also be configured to use various techniques to transmit in-band beacon bursts (e.g., low or high power beacon bursts) to the mobile device in the macrocell frequency range to trigger the mobile device to perform an inter-frequency scan for cell reselection. The femtocell may transmit communications signals to the mobile device in a femtocell frequency range (different from the macrocell frequency range) after the mobile device has discovered and selected the femtocell. |
