Abstract
System(s) and method(s) are provided to manage signaling in a femto cell access point. A pilot signal power profile, or pilot signal gating, determines transmitted a time-dependent pilot signal power. The power profile displays a duty cycle well below 100% and a power depth, which is the amplitude between maximum and minimum pilot signal power, determined partially upon radio link conditions. The time-dependent power profile can be established through a schedule based at least in part on attachment data or subscriber input; machine-learning method facilitate inferring the schedule. Pilot signal gating profile can be reused in a femto cell deployment to broaden femto cell identification and thus facilitate macro-to-femto handover. Activating/deactivating pilot signal in a femto cell in the scheduled and synchronized manner provided herein leads to macro-femto interference mitigation and mobility improvement(s), and improved battery life of wireless devices that operate in a wireless environment that includes femto cells.
