A wireless resource setting method comprising: a priority band acquisition step of acquiring, based on a notification from a neighboring wireless base station in a neighboring communication area next to a local station communication area of a wireless base station, a neighboring priority band preferentially used in the neighboring communication area; a communication path quality acquisition step of acquiring, based on a notification from a wireless terminal existing in the local station communication area, communication path quality concerning wireless communication of the wireless terminal with the wireless base station; a transmission rate calculation step (S102, S103) of calculating a first transmission rate when performing transmission to the wireless terminal with the communication path quality by a first transmission power in a first candidate band selected as a candidate from first wireless bands including the neighboring priority band out of wireless bands usable in the local station communication area and calculating a second transmission rate when performing transmission to the wireless terminal with the communication path quality by a second transmission power in a second candidate band selected as a candidate from second wireless bands that do not include the neighboring priority band out of the wireless bands usable in the local station communication area; and a wireless resource setting step (S104, S105, S106) of setting, out of a first wireless resource including the first transmission power and the first candidate band and a second wireless resource including the second transmission power and the second candidate band, a wireless resource for a higher transmission rate obtained by the calculation as a wireless resource allocatable to the wireless terminal. a priority band acquisition step of acquiring, based on a notification from a neighboring wireless base station in a neighboring communication area next to a local station communication area of a wireless base station, a neighboring priority band preferentially used in the neighboring communication area; a communication path quality acquisition step of acquiring, based on a notification from a wireless terminal existing in the local station communication area, communication path quality concerning wireless communication of the wireless terminal with the wireless base station; a transmission rate calculation step (S102, S103) of calculating a first transmission rate when performing transmission to the wireless terminal with the communication path quality by a first transmission power in a first candidate band selected as a candidate from first wireless bands including the neighboring priority band out of wireless bands usable in the local station communication area and calculating a second transmission rate when performing transmission to the wireless terminal with the communication path quality by a second transmission power in a second candidate band selected as a candidate from second wireless bands that do not include the neighboring priority band out of the wireless bands usable in the local station communication area; and a wireless resource setting step (S104, S105, S106) of setting, out of a first wireless resource including the first transmission power and the first candidate band and a second wireless resource including the second transmission power and the second candidate band, a wireless resource for a higher transmission rate obtained by the calculation as a wireless resource allocatable to the wireless terminal.
