RADIO BASE STATION, RADIO COMMUNICATION TERMINAL AND RADIO COMMUNICATION SYSTEM
First Claim
1. A radio base station that receives data transmission requests from a plurality of radio terminals and, based on information included in the data transmission requests, schedules the data transmission requests from said plurality of radio terminals and assigns bandwidths to said plurality of radio terminals, comprising:
- a device management unit that determines a duration time of bandwidth assignment to each of the radio terminals based on information on transmission data, which is included in the data transmission request from said radio terminal, and continues the bandwidth assignment to the radio terminal for the duration time.

Abstract
A radio base station, a radio communication terminal, and a radio communication system that can efficiently utilize broadband resources even if many packets of different sizes and different QoS requirements are mixed when sent and received. When a data transmission request is sent from a radio terminal to a base station, at least one of a data transmission duration time, a transmission data transmission interval, and an expiration time is included in the data transmission request. The base station receives data transmission requests from multiple radio terminals, schedules the data transmission requests from multiple radio terminals, assigns bandwidths to the multiple radio terminals based on the duration time, transmission interval, and expiration time included in each of the data transmission requests and continues the assignment of bandwidths to the radio terminals during the duration time based on the received duration time.
