Abstract:
1. A radio base station for transferring signals of time division multiplexed frames with respect to a plurality of radio terminals, the radio base station comprising: a beam formation unit configured to form a plurality of space dividing beams simultaneously; a plurality of antenna elements configured to transfer the signals with respect to the radio terminals by transmitting the plurality of space dividing beams toward the radio terminals; and a scheduling processing unit configured to allocate communication bandwidths to the radio terminals such that there is substantially no mutual interference among those signals to be transferred by different frames, with respect to a plurality of frames that are corresponding to at least one of the plurality of space dividing beams, wherein the scheduling processing unit allocates communication bandwidths of an identical time in different frames to different radio terminals such that there is substantially no mutual interference among those signals to be transferred at the identical time with respect to the different radio terminals, and then allocates entire frame configuration information indicating frame configurations of all the time division multiplexed frames to one of the time division multiplexed frames, wherein the entire frame configuration information includes information of locations where the communication bandwidths of the identical time are allocated in all frames.
