CPC H04W 4/42 (2018.02) [H04B 17/309 (2015.01); H04W 4/44 (2018.02); H04W 72/044 (2013.01); H04W 72/542 (2023.01); H04W 84/005 (2013.01)] | 9 Claims |
1. 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 apparatus comprising:
a transmission quality measurement circuitry 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, a resource allocation circuitry to
determine, based on the transmission quality of each frequency channel evaluated by the transmission quality measurement circuitry, 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 resource allocation circuitry when the allocation information is obtained, or using the reserved resource time slot when the allocation information is not obtained.
