A base station device includes: a receiver that receives an allocation request that requests allocation of a radio resource that is used to transmit first data; a scheduler that allocates, to the first data when the allocation request is received by the receiver, a part of an uplink radio resource allocated to second data for which a larger delay than a delay allowed for the first data is allowed; and a transmitter that transmits an uplink indication signal indicating that the part of the uplink radio resource is allocated to the first data by the scheduler.
