An avatar display device (20) includes: an obtaining part (210) that obtains captured image data of a person; a second obtaining part (211) that obtains, from the captured image data, depth data or image data of the person; a generating part (212) that composes a 3D model in accordance with the depth data or image data to generate an avatar; and a display part (213) that displays, in an image display area (31) of an information communication device (30), the avatar that is caused to follow a motion of the person.
Mobile communication systems and radio resource control methods are provided, by which interference between two or more base stations can be suppressed and an inter-cell adjusting control of radio resources for each of the two or more base stations can be simplified in a mobile communication system including two or more base stations, at least a part of each cell of the base stations being mutually overlapped. Two or more cell layers are configured by grouping the two or more base station. An inter-cell adjusting control of radio resources (for example, at least one of a synchmnization control of time slots and an allocation control of time slots) between the two or more cell layers is performed. An inter-cell adjusting control of radio resources between two or more base stations included in the cell layer (for example, at least one of a synchronization control of time slots and an allocation control of time slots) for each of the cell layers is also performed.
The present invention allows a difference between times at which downlink signals synchronously transmitted from a macro cell base station and a small cell base station, respectively, arrive at a communication terminal device to fall within a permissible range without being affected by a transmission delay in transmission cables or a propagation delay in wireless transmission paths of the base stations. A small cell base station is provided with a wireless transmission/reception unit that is connected to an antenna, a wireless communication control unit, a transmission cable that connects the wireless transmission/reception unit and the wireless communication control unit, and a downlink signal reception unit that receives downlink signals transmitted from the macro cell base station and the small cell base station, respectively. The small cell base station measures a reception timing difference between the downlink signals transmitted from the macro cell base station and the small cell base station itself, respectively, on the basis of the reception result of the downlink signals, adjusts the transmission timing of the downlink signal from the station itself on the basis of the reception timing difference, and transmits the downlink signal at the adjusted transmission timing.
Provided are a base station, a mobile communication system, and a handover control method that make it possible to prevent handover failure or a ping-pong handover phenomenon caused by interference from neighboring cells with respect to a serving cell. If a received power difference (S2 - S1) between received power S2 from a neighboring second base station that is fed back from a mobile station and received power S1 from a first base station to which the mobile station is connected is greater than a predetermined threshold, the first base station requests the second base station to terminate transmission of a downlink signal including a data signal and/or a control signal. In response to the request to terminate transmission, the second base station determines a wireless resource for which transmission of the downlink signal is to be terminated and notifies the first base station, and terminates the transmission of the downlink signal. The first base station allocates, as a wireless resource to be used for a downlink signal with respect to the mobile station, a wireless resource notified from the second base station or a wireless resource including a part thereof.
In a mobile communication system using a mobile-type radio relay apparatus that forms a plurality of cells toward the ground or the sea while moving in an upper airspace, a deterioration in communication quality, which is caused by a Doppler shift of a reception signal due to a relative movement of a radio relay apparatus with respect to a terminal apparatus of each of a plurality of cells or a feeder station on the ground or on the sea, is suppressed. The communication system comprises a mobile-type radio relay apparatus that is disposed movably by flying in an upper airspace, forms a plurality of cells from an antenna at a predetermined altitude toward the ground or the sea, and perfoims a radio communication with a terminal apparatus located in each of the plurality of cells.

A communication system, a base station and a communication control method are provided, which are capable of cooperatively transmitting data from a plurality of base stations to a plurality of communication terminals using a same radio resource. A first base station acquires a value of an interference suppression parameter that is applied to a transmission signal from the first base station so as to suppress interference from a second base station in a first communication terminal, when the first communication terminal locates in a cell border area.
