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.
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.

COMMUNICATION SYSTEM, BASE STATION AND COMMUNICATION CONTROL METHOD
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. The second base station duplicates a desired data for a second communication terminal located in a cell of the second base station, and transmits the duplicated desired data to the first base station. The first base station generates a transmission signal based on the value of the interference suppression parameter, the desired data for the first communication terminal, the desired data for the second communication terminal received from the second base station and a control information on data cooperative transmission, and the second base station generates a transmission signal of the desired data for the second communication terminal. Each of the base stations cooperatively transmits the transmission signal at a predetermined data cooperative transmission timing.

LOCATION-AWARE "GHOST" PROFILES IN A BALLOON NETWORK
Disclosed embodiments may help a balloon network to provide substantially continuous service in a given geographic area. An example method may be carried out at a balloon that is at a location associated with the first geographic area in a balloon network that includes a plurality of geographic areas. The balloon may determine that it should update its balloon-state in accordance with a balloon-state profile for the first geographic area. Then, in response, the balloon may determine the balloon-state profile for the first geographic area, which may include one or more state parameters for balloons operating in the first geographic area. The balloon may then operate according to the balloon-state profile for the first geographic area.
A balloon may include an optical-communication component, which may have a pointing axis. A pointing mechanism could be configured to adjust the pointing axis. The optical-communication component could be operable to communicate with a correspondent balloon via a free-space optical link. For example, the optical-communication component could include an optical receiver, transmitter, or transceiver. A controller could be configured to determine a predicted relative location of the correspondent balloon. The controller may control the pointing mechanism to adjust the pointing axis of the optical- communication component based on the predicted relative location so as to maintain the free-space optical link with the correspondent balloon.
