A method for distributing uplink bandwidth of wideband radio access system includes calculating out parameter of desired distribution bandwidth on next uplink sub frame at user station as per service quality parameter and historical connection state of user station service stream by base station, updating bandwidth parameter of current uplink sub frame at user station as per calculated out parameter and using it as bandwidth parameter of next uplink sub frame, reupdating bandwidth parameter of next uplink sub frame as per bandwidth parameter of system interface and using reupdated bandwidth parameter as actual bandwidth distributed to user station. |
