  • Patent number: 10454507
    Abstract: The communication device includes a switching controller. In a case where the communication band to be used is a second frequency band between a second lower edge frequency and a second upper edge frequency or in a case where the communication band to be used is a first frequency band between a first lower edge frequency and a first upper edge frequency and a frequency of the signal to be used is included in a first passband, the switching controller controls a filter switcher to switch to a first filter. In a case where the communication band to be used is a third frequency band between a third lower edge frequency and a third upper edge frequency or in a case where the communication band to be used is a first frequency band and the frequency of the signal to be used is included in a second passband, the switching controller controls the filter switcher to switch to a second filter.

  • Publication number: 20180316411
    Abstract: A relay apparatus is provided which is capable of properly executing beamforming for radio communication from the relay apparatus to a donor base station, while inhibiting occurrence of beam interference in its surrounding area as much as possible. A relay apparatus 20 includes: an amplitude and phase measurement unit 25 that measures an amplitude and phase of radio communication from a donor base station 30 to the relay apparatus 20; a beam adjuster 27 that performs beamforming by adjusting a combination of a plurality of antennas; and a base station judgment unit 29 that judges base stations; wherein the adjustment for the beamforming is made so that a relatively strong beam is directed towards the donor base station 30 and a relatively weak beam is directed towards base stations other than the donor base station 30.

  • Publication number: 20180279196
    Abstract: In order to implement a relay apparatus capable of suppressing frequency of handover which may occur between macro cell base stations, a relay apparatus 20 relays communication between a terminal device 10 and a macro cell base station 30 and establishes a connection to a specified macro cell base station 30 on the basis of connection point identification information for identifying the macro cell base station 30 which is a connection point; and even when the relay apparatus 20 receives a connection switching request form a core network side to switch the connection from a macro cell base station 30-1 to another macro cell base station 30-2, the relay apparatus 20 prohibits switching of the connection to the other macro cell base station 30-2 pursuant to the connection switching request.

  • Publication number: 20180279205
    Abstract: The fairness of radio communication between a donor base station and terminal devices is maintained. A relay apparatus 20 for relaying radio communication between one or more terminal devices 10 and a donor base station 30, wherein when the relay apparatus 20 receives a cell restriction instruction from the donor base station 30 to restrict a quantity of terminals capable of existing in a service area of a cell formed by the donor base station 30, the relay apparatus 20 executes processing for avoiding cell restriction operation on itself and transfers the cell restriction instruction received from the donor base station 30 to the terminal devices 10 existing in a service area of a cell formed by the relay apparatus itself.

  • Publication number: 20180270810
    Abstract: A relay apparatus is a relay apparatus that relays communication between a terminal device and macro cell base station in order to implement a relay apparatus capable of preventing a disconnection between the macro cell base station and the relay apparatus, wherein when starting a new connection for radio communication, the relay apparatus acquires identification information for identifying the other end of the radio communication, checks connectability information for defining whether connection to the other end of the radio communication can be established or not against the identification information, and determines whether the connection for the radio communication can be established or not.
