PROBLEM TO BE SOLVED: To reduce discard/retransmission of packet data even when the total value of communication bandwidth used for data transmission to radio terminals exceeds bandwidth available to a base station. ! SOLUTION: A base station includes: a downstream resource management unit for allocating a communication resource defined with unit time and a division band obtained by performing division in the frequency direction into a plurality of bands to a radio terminal, depending on a downlink data amount required by the radio terminal; an upstream resource management unit for allocating a communication resource for transmitting an uplink signal, to the radio terminal; and a first transmission/reception control unit which executes control of transmitting a downlink signal to the radio terminal on the basis of the communication resource allocated by the downstream resource management unit and executes control of receiving an uplink signal from the radio terminal on the basis of the communication resou |
