ABSTRACT:
A stochastic method and apparatus schedules airtime in a radio communication system having a plurality of transmission protocols. At a queue measurement time airtimes are measured (402) that are required for transmitting messages stored in queues (222) corresponding to the plurality of transmission protocols. A corresponding plurality of estimated arrival rates are determined (404) equal to estimated rates of increase of the plurality of airtimes due to arriving traffic. An objective function is structured (408) equal to a sum of penalties corresponding to the plurality of transmission protocols, the penalties dependent upon the plurality of airtimes and the plurality of estimated arrival rates, and further dependent upon an optimal airtime allocation decision. The optimal airtime allocation decision is derived (410) by minimizing the objective function, and then airtime is allocated (412) among the plurality of transmission protocols in accordance with the optimal airtime allocation decision.
