Abstract:
1. A frame configuration method for time division multiplexed frames to transfer signals between a radio base station and a plurality of radio terminals, the frame configuration method comprising: (a) allocating 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 (b) allocating entire frame configuration information indicating frame configurations of all the time division multiplexed frames to one of the time division multiplexed frames, wherein the step (b) allocates the entire frame configuration information to a frame to which a control information to be transmitted to all the radio terminals simultaneously is allocated, wherein when there is a difference between total sums of the communication bandwidths allocated to the time division multiplexed frames, the step (a) allocates a next communication bandwidth to a frame for which a total sum of allocated communication bandwidths is the smallest among the time division multiplexed frames, wherein the step (a) determines the next communication bandwidth to be allocated such that a total sum of allocated communication bandwidths for a reference frame selected in advance among the time division multiplexed frames is not exceeded by a total sum of allocated communication bandwidths for any other time division multiplexed frames.
