  • Patent number: 9288022
    Abstract: A wireless cellular network includes a plurality of cells, each cell including a base station for serving one or more mobile users. For controlling an operation within a cell of the wireless cellular network, a fuzzy logic is used. The input variables for the fuzzy logic include input variables determined on the basis of information only locally available in the cell.
    Type: Grant

  • Patent number: 9071404
    Abstract: To reduce interference that a user terminal connecting to a base station apparatus forming a large-scale cell undergoes from a base station apparatus forming a small-scale cell in a radio communication system in which the small-scale cell is provided in the large-scale cell, a femto-base station forming a femto-cell provided in a macro-cell receives cell identification information of a macro-base station, determines cell identification information of the femto-base station based on the received cell identification information of the macro-base station so as to reduce interference to a control format indicator channel assigned to radio resources by the macro-base station, and controls assignment of control channels to radio resources based on the determined cell identification information of the femto-base station.

  • Publication number: 20130170423
    Abstract: In a radio communication system in which a micro cell is provided in a macro cell, when a user terminal that is connected to the macro base station is located in the micro cell, interference signals which the user terminal receives from the micro base station are reduced.

  • Patent number: 8472886
    Abstract: A mobile transceiver apparatus being adapted for communicating radio signals from/to a base station transceiver. The mobile transceiver apparatus has a receiver module for receiving an information signal from an other base station transceiver, wherein the information signal being received with an information signal strength. The mobile transceiver apparatus further has a transmitter module for communicating a transmit radio signal with a transmit power to the base station transceiver, wherein the transmit power being dependent on the information signal strength received from the other base station transceiver.

  • Publication number: 20130150060
    Abstract: The present invention provides a base station apparatus, a mobile terminal apparatus and a communication control method that support a next-generation mobile communication system and are capable of controlling in an adaptive manner to interference in a heterogeneous network. Provided is a room base station apparatus (30) that covers a femto cell (C2) and shares at least a part of frequency band with a base station apparatus (20) that covers a macro cell (C1), the room base station apparatus (30) comprising: a detecting section (311) configured to detect an unconnected mobile terminal apparatus (10) in the femto cell; an obtaining section (312) configured to obtain resource identification information for identifying a resource of a PDCCH for the unconnected mobile terminal apparatus (10) in the base station apparatus (20); and a blank resource setting section (313) configured to set a resource identified by the resource identification information to be a blank resource.
