    摘要： The wireless communication apparatus includes transmitter modules and receiver modules for carrying out transmission/reception via a plurality of antenna beams formed by an adaptive array antenna between stations. The apparatus is provided with an end time detecting section and a maximum reception end time is detected by detecting section based on reception signals on the receiver modules. A reception end signal is generated from a notifying section, when current time counted by a counter is reached to the maximum reception end time. The transmission enabling section causes the transmitter modules to transmit data in response to the reception end signal.

    摘要： In a radio base station, a plurality of time division multiplexed frames are transmitted through a plurality of space dividing beams such that it becomes possible for the radio base station to realize the radio communications with different radio terminals at the same time using the same frequency, by using a scheduling processing which allocates 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.

    摘要： According to one embodiment, a wireless communication apparatus includes a determination unit, a first setting unit, a second setting unit and a wireless unit. The determination unit determines whether a signal degradation degree is higher than a threshold value. The first setting unit sets first parameters relating to a first data rate and a first communication robustness. The second setting unit sets second parameters relating to a second data rate and a second communication robustness if an instruction signal is received and if the signal degradation degree is higher than the threshold value. The wireless unit communicates with a communication partner using one of the first parameters and the second parameters.
