20140241445 | Method for providing quality of service in a multiuser orthogonal frequency division multiplex (OFDM) system - A method that provides quality of service in a multiuser orthogonal frequency division multiplex system. The method assures quality of service at application level, which directly affects user's satisfaction with the service for interactive applications, such as web browsing, and real-time applications. The method uses advanced dynamic resource allocation to achieve a common subjective user state and/or dynamic resource allocation to optimize the throughput of the system while increasing the quality of service at application level. The method takes advantages of the information of the instantaneous channel gain and information of the objective technical parameters of the system and applications. With the incorporation of the technical parameters of the system and applications into the subcarrier allocation, the method may provide quality of service at application level, allow explicit control of system resources, ensure fairness in resource allocation and achieve the optimal throughput of the multiuser orthogonal frequency division multiplex system. | 08-28-2014 |
