摘要： A radio communication system 1 comprises a picocell base station PeNB placed within a communication area of a macrocell base station MeNB and has transmission output lower than the macrocell base station MeNB. A coverage of the picocell base station PeNB is expanded. A usable resource being a radio resource which a high-power base station is allowed to use as PDSCH is determined on the basis of a degree of expansion of coverage of a low-power base station.

摘要： A high power base station (100), when having detected a small cell (PC1) that is formed by a low power base station (200) and that is a source of interference, decides both a cell-edge band, which is used in a cell-edge area (MC1OUT and a cell-center band, which is used in a cell-center area (MC1IN), in such a manner that the cell-edge and cell-center bands are different from each other. Further, the high power base station (100) transmits the decided cell-center band to the low power base station (200). The low power base station (200) then decides, as the small-cell band, the cell-center band received from the high power base station (100).

摘要： PROBLEM TO BE SOLVED: To provide a radio communication system efficiently making adaptive control in an MIMO or the like even if channel fluctuation is large as in high-speed travel of a terminal. SOLUTION: A channel estimation and prediction section 18 estimates a channel and performs channel prediction for a next transmission slot. An SVD section 19 performs singular value decomposition of each channel prediction value. A characteristic value calculation section 20 calculates a characteristic value within a slot, and a characteristic mode quality calculation section 21 calculates the quality of each characteristic mode based on a characteristic value obtained from the characteristic value calculation section 20 for outputting to a transmission adaptive control section 22. The transmission adaptive control section 22 grasps the fluctuation frequency of a channel, for example, from fluctuation in quality of a lower-level characteristic mode, and corrects the quality of the upper-level characteristic mode to a smaller value as the fluctuation frequency of the channel becomes larger as compared with slot length.

摘要： PROBLEM TO BE SOLVED: To shorten a convergence time of weight calculation and improve reception quality in an adaptive array antenna. SOLUTION: A receiver is provided with a weight updating section 17 for adaptively updating a weighting value used for weighting a reception signal of each antenna element so that reception quality of a desired signal can be improved; TS complex correlation calculating sections 15-1 and 2 for executing vector operations between a first known signal included in the desired signal and the reception signal and between a second known signal included in an interference signal and the reception signal, and calculating relation in amplitude and phase between the desired signal included in the reception signal and a first known signal and between an interference signal included in the reception signal and a second known signal; and an initial weight determining section 16 for controlling the update of the weight updating section 17 so that a weight value at which the interference signals included in the reception signals received by each antenna element cancel each other and are suppressed can be calculated from a result of the vector calculations.

摘要： A radio communication system (1) includes a pico-cell base station (PeNB,) which is located in the communication area of a macro-cell base station (MeNB) and the transmission power of which is lower than that of the macro-cell base station (MeNB) . For radio resources that can be used as PDSCH, a resource division ratio that is a ratio between unusable PDSCH resources, which cannot be used by the macro-cell base station (MeNB), and usable PDSCH resources, which can be used by the macro-cell base station (MeNB), is decided, and a radio resource is allocated, out of the usable PDSCH resources defined in accordance with the decided resource division ratio, to a radio terminal that is to connect to the macro-cell base station (MeNB). The resource division ratio is decided based on the traffic load of each base station.
