Classification: CPC H  B | IPC H

Claim 7:
8. A control circuit to control a wireless communication apparatus to allocate radio resources, which is a base station or a mobile station to transmit a data series on a frequency channel in a frequency hopping pattern corresponding to a radio resource time slot,
the control circuit causing the wireless communication apparatus to
measure radio waves in a frequency band used in the transmission of the data series and evaluate transmission quality of each frequency channel, and
the radio resources including a reserved resource that is a time slot fixedly allocated to the mobile station located in a cell that is a communication range of the base station, and a spare resource that is a time slot that can be allocated to the mobile station located in the cell,
determine, based on the evaluated transmission quality of each frequency channel, whether the following apply: (1) the mobile station's transmission quality of the frequency channel used in the reserved time slot is lower than or equal to a threshold value, and (2) the spare resource time slot uses a frequency channel that is of the same transmission quality as, but a different frequency band than, the frequency channel used in the reserved resource time slot, and
in response to determining both (1) and (2) apply, allocate the spare resource time slot to the mobile station, wherein

the mobile station transmits the data series, using the spare resource time slot indicated by allocation information that indicates the spare resource allocated by the control circuit when the allocation information is obtained, or using the reserved resource time slot when the allocation information is not obtained.
