摘要： According to one embodiment, an allocating unit of a wireless communication device finds for each user an unallocated radio channel having maximum communication quality as a first radio channel, and calculates a first metric matching a communication state using communication quality in the first radio channel, selects one user from the plurality of users based on the first metric and allocates the first radio channel to the selected user. Further, the allocating unit repeats allocating an unallocated radio channel adjacent to a radio channel allocated to the selected user on a frequency domain until predetermined conditions are satisfied.

摘要： According to one embodiment, a communication device communicates with N remote units. Each remote unit includes a plurality of antennas, wireless transmitting units, and wireless receiving units. The communication device is provided with a received signal processing unit, to which received signals by a plurality of the wireless receiving units are combined and input, and which specifies the remote unit subjected to interference, and a switch which decreases a reception gain of the wireless receiving unit included in N−1 remote units out of the N remote units in a predetermined measurement section. The received signal processing unit calculates a correlation value between the combined received signals and a reference signal transmitted by a user terminal connected to another base station system in the measurement section and specifies the remote unit subjected to the interference by the second user terminal based on the correlation value.

摘要： A first extended base station that forms a first cell and a second extended base station that forms a second cell operate for a cooperative communication of transmitting same data to a user terminal located in the first cell. A second signal processor that corresponds to the second extended base station generates a training signal specific to the first extended base station and the first extended base station and the second extended base station transmit same data and same training signals. Thus, a cooperative communication can be realized in a system that uses a training signal specific to a base station.
