Abstract: Multicast transmission and inter-cell interference coordination can be flexibly switched using Multicast-Broadcast Single Frequency Network (MBSFN) subframe without reduction of resource utilization efficiency. A transmission data determination unit determines that a first area is used as either of a first subframe performing multicast transmission or a second subframe performing inter-cell interference coordination based on presence or absence of transmission data in each of the first area which is configured to have at least some subframes among a plurality of MBSFN subframes. Wireless communication IF unit performs a transmission process in the first area according to a determination result.

Abstract: A base station receives signals transmitted from one terminal in cooperation with another base station and performs synthesis processing of the received signals of the other base station and the received signals of the local base station. In the base station, a determination circuit determines necessity of synthesis processing using the received signals of the local base station at the time of the first transmission of the terminal. A base station-to-base station communication circuit transmits a message requesting forwarding of the received signals to the other base station in a case where the synthesis processing is determined to be necessary and receives the forwarded signals that are forwarded from the other base station at the time of retransmission of the terminal. A synthesis circuit synthesizes the forwarded signals from the other base station and the received signals of the local base station in a case where the synthesis processing is determined to be necessary.

Abstract: A base station device includes: a receiver, which, in operation, receives signals from one or more other base station devices in a system using an adjacent frequency band; a searcher, which, in operation, searches for one or more center frequencies of signals from the one or more other base station devices; a selector, which, in operation, selects a synchronization target base station device from which a respective center frequency has been acquired from among the one or more other base station devices; and a controller, which, in operation, sets an operation parameter to establish synchronization with transmission and reception timings of the synchronization target base station device.

Abstract: In a base station that transmits data to a first terminal in coordination with a coordination-providing base station, and functions as a connection-making base station that instructs the coordination-providing base station on a transmission parameter that is used for coordinated communication, a reception processor receives first CSI between the connection-making base station and the first terminal from the first terminal, and, receives, from each of at least one or more second terminals other than the first terminal, second CSI between the connection-making base station and a second terminal, and third CSI between the coordination-providing base station and at least one second terminal, a CSI estimator configures the third CSI which corresponds to a terminal, to which the first CSI and the second CSI are the closest, of the at least one or more second terminals, as an estimation value of CSI between the coordination-providing base station and the first terminal.
