Abstract: The present invention refers to operating of power amplifiers of base stations in a communications network, wherein each power amplifier is assigned to a corresponding antenna of a base station and enables receiving and/or transmitting of information signals in an area of the communications network covered by the corresponding antenna. The operating comprise& includes switching off of a number of power amplifiers of a base station so that at least one power amplifier of the base station is left on, if level of load in the communications network is detected as being low; and switching of a signal of the at least one power amplifier to antennas, to which power amplifiers of the number of power amplifiers are assigned.

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: A method and apparatus for detecting and determining the location of a coverage hole in a communications network such as a cellular communication system wherein the location is determined from operational parameters and/or by network elements themselves. Additionally is a method to reduce a hole by adjusting antennae parameters preferably remotely and automatically and this can be done in conjunction with hole location to optimise the system.

Abstract: A network node for connecting a network with a terminal is described, wherein the network node includes a sleep control device. The sleep control device includes a terminal linking device and a network linking device. The terminal linking device is adapted to connect to a terminal, wherein the network linking device is adapted to connect to a network. Furthermore, the network node is adapted to enter a standby mode, wherein the sleep control device is further adapted to switch on the network node on appearing of at least one trigger event of (i) appearing of a predefined signal sequence on the terminal linking device during a monitoring period of a listen cycle or (ii) appearing of a terminal paging signal sequence on the network linking device. The sleep control device is adapted to detect during the monitoring period the predefined signal sequence on the terminal linking device.
