Abstract: The present invention relates to methods, apparatuses, a system and a computer program product for reducing interference and energy consumption of wireless devices. An apparatus, namely a femto base station or home (e) NodeB, can include a transmitting unit, a receiving unit, a determining unit, a disabling unit, a disabling handshaking unit, and a reassigning unit. If the determining unit determines that there is no active communication between the apparatus and a user device, the disabling unit may disable the transmitting unit and the receiving unit while maintaining a connection between the apparatus and a network. A disabling handshaking can be performed by the disabling handshaking unit to achieve this, wherein the re-assigning unit may re-assign one or more user device(s) to a network apparatus, namely a macro (e) NodeB.

Abstract: There is provided a method and an apparatus for determining an adjustment of a tilt angle (?1, ?2) for a beam emitted from an antenna (130) of a base station (100) which is serving a vertically sectorized cell (150) of a cellular radio telecommunication network.
