A network apparatus may include a memory and processing circuitry configured to receive first connection metrics of a connection with a user equipment that is using a first configuration during a first connected state; receive second connection metrics of the connection with the user equipment during a transition to a second connected state; choose a selected configuration as (i) the first configuration or (ii) a second configuration for the second connection state based on the first connection metrics and the second connection metrics; and send the selected configuration to the user equipment.

User equipment configuration

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.

There is provided a method and an apparatus for determining an adjustment of a tilt angle (&#x3b1;) for a beam emitted from an antenna () of a base station () which is serving a vertically sectorized cell () of a cellular radio telecommunication network. The method comprises (a) configuring user equipments () being located in the vertically sectorized cell () with dedicated measurements, (b) collecting the dedicated measurements for a specific time interval, (c) obtaining a spatial user equipment distribution among a first sector () of the cell () and a second sector () of the cell () based on the collected dedicated measurements, (d) ascertaining an optimized spatial overlap region between the first sector () and the second sector () based on the obtained spatial user equipment distribution, and (e) determining the adjustment of the tilt angle (&#x3b1;) based on the ascertained optimized spatial overlap region.

Systems and techniques for antenna optimization are described. Information such as statistics relating to conditions are collected, and evaluated against specified criteria in an iterative process. An antenna tilt decision is made based on the evaluation and validated to determine if it should be retained or repeated, or if the tilt should be returned to a previous state.

MIMO communication system

A method and a mobile station for controlling interfrequency handovers of the mobile station is provided. The target value for a quality factor of the received downlink signal is used in determining a need for an interfrequency handover. The target value of the handover control method may be equal to the target value of the downlink outer loop power control, or target value of handover control may depend on the target value of the downlink outer loop power control. As the target value of the downlink outer loop power control is updated, the target value of the handover control is typically updated, too. The same target values, or values that depend on the downlink outer loop power control target values, for example, via a known function, are used in controlling interfrequency handovers. A method according to the preferred embodiments of the invention detects this situation and preparations for an interfrequency handover are typically initiated.

A connection establishment method for establishing a random access type connection using a random access channel, which is used in a radio system having several subscriber terminal equipments (to) and base stations (to) where one or more transceiver units (to) operate, and in which system connection establishment between one of the subscriber terminal equipments (to) and the base station (to) is possible when the one subscriber terminal equip nt (to) is situated in the coverage area of one or more transceiver units (to) of the base station, where the one subscriber terminal equipment (to) evaluates the quality of the connections to be established. Starting from a condition in which no connection is established with the one subscriber terminal equipment, the one subscriber terminal equipment (to) forms a random access type connection to more than one base station transceiver unit (to) included in one or more base stations (to).m
