Abstract:
1. A method of allocating a plurality of sub carriers among a plurality of applications in a wireless network, said plurality of applications being executed on corresponding terminal devices, said plurality of sub carriers being formed by dividing a frequency spectrum, each of said plurality of applications having a corresponding required quality of services (QoS), said method comprising: determining a first set of parameters representing said required QoS and a second set of parameters representing an observed QoS for each of said plurality of applications; computing a corresponding number of sub carriers to be allocated in each of a sequence of time slots to respective ones of said plurality of applications using said first set of parameters and said second set of parameters; and allocating said corresponding number of sub carriers to respective ones of said plurality of applications in the corresponding one of said sequence of time slots; wherein said computing calculates a difference of the observed and the required values of the corresponding parameters in determining said corresponding number of sub carriers; and wherein said first set of parameters comprises at least one of a required delay bound, a required throughput, a required average delay for each of said plurality of applications and wherein said second set of parameters comprises at least one of an observed queue length, an observed throughput, an observed average delay, and an observed delay bound for each of said plurality of applications.
