RADIO SCHEDULING DEVICE AND METHOD, AND RADIO DEVICE

PROBLEM TO BE SOLVED: To provide a radio scheduling device capable of supplying delay guarantee in a radio zone, and improving a radio frequency utilization efficiency. SOLUTION: The radio scheduling device comprises a long zone selector 23 and a short zone selector 24. The long zone selector 23 conducts screening a radio flow candidate to be assigned with an access right in a long zone including a plurality of periods when one access right becomes effective based on urgency of a radio flow, and conducts classification for a type of the radio flow, based on a request to delay quality. The short zone selector 24 selects a radio flow to be assigned with an access right for each period when the access right becomes effective out of the screened candidates, and controls selection of radio flows in response to the request to delay quality according to the type of the radio flow.
