INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## 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. ## Claims ### Claim 1 A method comprising: determining, by a base station in a wireless communications network, whether there is an active wireless communication data session, based on wireless transmission and reception of the base station, between the base station and a user device while the user device is assigned to the base station;
